Application of Light Sensing Technology in CNC Machine Tools
Xinggan Technology, the application of CNC numerical control, Qinghai Heavy Machinery Machine Tool Co., Ltd., the 808 machine tool is a special machine tool for processing the train wheel to the rim tread. Its tool routing is a plane curve, in order to determine the tool in two directions. On the initial position, we used a two-contact positioning device as follows. The entire tool setting device is mounted on the upper cover of the tool holder, the two contacts 6, 6 are mounted on the guide bars 1 and 2, and the guide bars 1 and 2 are mounted on the casing 3 of the tool setting device, the rear portions of the two guide bars are The return springs are mounted in different directions, and the guides are also provided with a finger 4 and 6. When the tool is turned, the spring is compressed, and the contacts approach the sensitive portion of the switch 5 to generate a signal. The proximity switch 5 is mounted in the casing 3, and the thrust cylinder 7 at the rear of the casing 3 is used to control the extension and retraction of the tool setting device. The underside of the cutter device casing is associated with the tool holder cover plate, and the matching size is 1867. Ding-shaped guide keys.
5. Proximity switch 7. Thrust cylinder 1. Working principle The thrust cylinder 7 pushes the casing 3 to the operable position, and then the entire tool setting process is completed under the control of the numerical control system.
Press the program run command on the control panel to start the tooling process. The tool holder first advances in the negative direction of the shaft. When the contact element hits a certain point on the rim surface and compresses the spring to make the contact finger 6 reach the sensing distance of the proximity switch 5, the proximity switch 5 sends a signal, and the tool holder Start moving along the 2 axis, while the contact retracts the distance, disconnects the signal, and gives up part of the moving space. When the contact 3 touches the wheel end face and compresses the spring, the finger 4 also causes the proximity switch 5 to signal, at which time the tool holder moves again in the negative direction of the long axis.
When the contacts are compressed again and the two proximity switches have signals at the same time, the thrust cylinder 7 contracts, and the tool box casing 3 is retracted. The tool setting process ends, and the position of the tool holder at this time is the cutting initial position of the tool. The machine can be cut according to the existing cutting program.
The proximity switch is selected to be 23, the sensing distance is 3, the highest switching frequency is 15, the voltage is 1030, the maximum load current is 120, and the sensing distance is 18,18. The optical sensing technology is an advanced sensing technology, and the proximity switch is sensitively installed. Simple, small size, high strength and high anti-interference ability. After being applied to the tool setting device, the manual tool setting is changed into automatic tool setting, which improves the accuracy of the tool setting and improves the machining accuracy, especially the processing of the special profile surface, and also reduces the labor efficient MAG of the tool setting. The new development of welding, the status quo of the real-life lost foam casting, the compound gestation technology and the application of the inverted gestation technology on the diesel engine body. The shell size of the ductile iron castings is oversized to prevent the improvement of the Pochang system to reduce the experience of the hydraulic coupling of the steel pipe parts. Squeeze Casting Process of Die Casting Die Metal Cylinder Control of Diesel Engine Cylinders The Influence of the Shape of the Clamping Punch Shape of the Behind-Rear Bevel Gears on the Material Flow of the Rear Axle Reduces the Closed Height of the Composite Blanking Die Suspension New, hot steel welding process research stainless steel composite steel plate container welding adjustment head cutting instrument escalator skeleton group, process improvement Ding 10 tungsten argon arc welding torch improvement welding bevel processing method selection spray nine strengthening Discussion on heat treatment of single-column hydraulic cylinder live column of seepage gear fatigue strength analysis of rolling straight shank twist drill performance test failure analysis before blasting Blue liquid degreasing to improve blasting quality and efficiency of blackening workpiece quality Dong control jack hydraulic cylinder cold extrusion process and wedge tool 镦 hot forging 蜾 bolt head forming mold design double bevel edge cutting tongue bending die Design automatic crimping and deepening leveling die elastic lock washer composite die design fast and suitable computer drawing six quenching media selection and use maintenance
Humidification can also moisturize the skin, promote blood circulation and metabolism of facial cells, relieve nervous tension and eliminate fatigue.
According to experts' experiments on the comfort of human activity environment, people feel most comfortable when living and working in an environment with relative humidity of 40% - 60%, and the work efficiency is also high. At this time, the air also has a good protective effect on furniture and decoration.
Some plants can be placed when the indoor air is dry. It is recommended to choose tiger tail orchid, aloe or Chlorophytum, which can release oxygen at night. Don't put too much in the bedroom. You can sprinkle some water on the leaves of plants.
If you want to better solve the problem of indoor dryness or the indoor air is too dry, it is recommended to use a humidifier. This is a relatively simple method. You can directly use tap water when choosing fog free humidification products. Remember not to add essential oils or fungicides in the humidifier indiscriminately. Sometimes adding things indiscriminately will have an adverse impact on your health, It is prone to bronchitis and lung diseases
Professional doctors suggest that you buy an ultrasonic Aroma Diffuser, which can effectively and immediately solve the problem of air drying!
Dry air is the main reason for the increase of dust and suspended particles, while bacteria can not exist alone and often adhere to dust. The elderly and young children have weak physical resistance and are vulnerable to bacteria and viruses. Warm and dry is the best environment for the breeding and transmission of many viruses and bacteria. Second, it is easy to cause excessive loss of body water, infect diseases and accelerate aging. In a dry environment, when we get up every morning, we will feel dry mouth, tight muscles and low mood.
In this case, professional doctors suggest you buy an ultrasonic aroma diffuser, which can effectively solve the problem of air drying. Through the high-frequency vibration generated by the ultrasonic vibration equipment, the aromatherapy machine decomposes water molecules and dissolved plant essential oils into nano cold fog with a diameter of 0.1-5 microns, which can be distributed into the surrounding air, which can moisturize the air and skin, Add some plant essential oils to make the air more fresh and fragrant and moisturize the skin
When the air is dry, the reproduction speed of influenza virus and Gram-positive bacteria that can cause infection is accelerated, and it is also easy to spread with the dust in the air and cause diseases. Dry air dehydrates human epidermal cells and reduces sebaceous gland secretion, resulting in rough, wrinkled and even cracked skin. Therefore, allergic diseases such as allergic dermatitis, skin itching and discomfort are also related to air dryness. Air drying also has an adverse impact on human immunity. At this time, the doctor suggested that it is necessary to buy a fumigant humidifier aroma diffuser to help us solve the problem of air drying
