The use of limit switch in machine tool industry

Limit switch in the use of machine tools have many, can be used to control the workpiece movement or automatic feed stroke, to prevent the occurrence of collision. Sometimes, the controlled object can automatically reverse between the two positions by using the limit switch, and then obtain continued reciprocating motion. For example, when cars that deliver data automatically reach the end, they hit a limit switch, connect to the rollover arrangement, and then flip the data inside the car back to the starting point. Arriving at the starting point, we hit the starting point of the travel switch, connected to the loading arrangement of the circuit, the initial automatic loading. Always, it became an automated, unguarded production line, working day and night to save manpower.

Limit switches usually refer to switches that are assembled in a housing, especially where there are special requirements for mechanical strength and environmental adaptability to maintain the built-in microswitches from external forces, water, oil, gas and dust. Shapes can be roughly divided into horizontal, vertical, and composite.

Limit switch products are widely used in the control of binding engineering construction, ports, mines and other operations of lifting and transmission machinery equipment space three coordinate. The limit switch consists of a high precision gear ratio reducer and a mechanical recall control device and sensor synchronized with the output shaft. Limit switch is widely used in construction machinery because of its small size, many functions, high precision, adjustable limit, strong versatility, maintenance, equipment, convenient adjustment and other characteristics.

Limit switch is divided into operation limit switch and upper limit switch. The job limit switch is more suitable for indicating that the arranged action is in place. The upper limit switch is to prevent the scheduling action beyond the planning and the occurrence of accidents. Operating limit switchgear The equipment can change the position of operating environmental conditions. After the switch action, supply signal, turn over some other action. The upper switchgear is at the far end of the scheduled action to maintain the scheduled damage caused by the scheduled overaction.
