Magnetic attraction type locking and positioning device

Abstract

The invention discloses a magnetic attraction type locking and positioning device. The magnetic attraction type locking and positioning device comprises a base, a cover plate, an electromagnetic suction cup, an electromagnetic suction cup supporting base, spring guiding rods and supporting type compression springs. The electromagnetic suction cup is arranged on the electromagnetic suction cup supporting base, and the electromagnetic suction cup supporting base bearing the electromagnetic suction cup is arranged in the base. The spring guiding rods sleeved with the supporting type compression springs are arranged between the electromagnetic suction cup supporting base and the base, and the cover plate is arranged on the base. The device can adjust the pre-tightening force, low-voltage direct current power supply is utilized, and the beneficial effects of stability, strong attraction force and small residual magnetism after the power failure are achieved; and functions are safer and morereliable, the structure is simple and economical, and mounting, dismounting, maintaining and component replacement are convenient.

Description

technical field [0001] The invention relates to a positioning device used for locking, positioning and fixing of magnetic induction materials, and belongs to the technical field of equipment manufacturing. Background technique [0002] For some movable equipment parts, it is often necessary to lock and locate reliably at a specific location to meet specific functions or working conditions. For this reason, locking and positioning devices have emerged and are widely used in various mechanical equipment. Traditional In machinery, the self-locking properties of mechanical structures, such as threads, eccentric wheels, and connecting rod mechanisms, are often used to achieve the purpose of locking equipment, and these mechanisms are either cumbersome to operate and limited in use; or the structure is relatively complex and the accuracy of the parts is relatively high high; or the service life of the parts is too short, the replacement is inconvenient, etc., which limit the devel...

[0002] For some movable equipment parts, it is often necessary to lock and locate reliably at a specific location to meet specific functions or working conditions. For this reason, locking and positioning devices have emerged and are widely used in various mechanical equipment. Traditional In machinery, the self-locking properties of mechanical structures, such as threads, eccentric wheels, and connecting rod mechanisms, are often used to achieve the purpose of locking equipment, and these mechanisms are either cumbersome to operate and limited in use; or the structure is relatively complex and the accuracy of the parts is relatively high high; or the service life of the parts is too short, the replacement is inconvenient, etc., which limit the development and application of the locking and positioning device; therefore, developing a locking and positioning device that can overcome the above defects has become a technology to be urgently solved by those skilled in the art question
