Linear motor anti-fall protection apparatus

Abstract

The invention relates to the technical field of linear motors and specifically to a linear motor anti-fall protection apparatus. The linear motor anti-fall protection apparatus comprises a solenoid, an iron core, a torsion spring, a hook, a slide block, a spring, and a pin roll. The solenoid is connected with the iron core. The slide block and the spring successively sleeve the iron core. The iron core is connected with the torsion spring through the hook. The linear motor anti-dropout protection apparatus is designed for protecting a motion mechanism and a contact surface in order that the mover of a linear motor, when motioning in the vertical direction, can be prevented from falling caused by disappearance of a motor enable signal due to a mistake of a driver or other reasons, solves a defect that the linear motor does not have a brake function, has a good practical application value, is simple and ingenious in structure and fast in overall response time, achieves common protection, and can be well used in actual production. It is believed that such protection structure can be well integrated into motor protection design and has good application prospect.

Description

technical field

[0001] The invention relates to the technical field of linear motors, in particular to an anti-drop protection device for linear motors. Background technique

[0002] Linear motors are also called linear motors or linear motors, which can be seen as being cut radially and flattened by a rotating motor. With the maturity of technology and the development of industry, the application of linear motors in engineering is becoming more and more common. At present, the most commonly used linear motors are plate type, U-shaped groove type and tube type. The typical mover coil is generally three-phase.

[0003] With the maturity of linear motor technology, linear motion can be directly provided by linear motors, eliminating intermediate motion conversion. Admittedly, linear motors have many unique advantages over conventional rotating mechanical systems in terms of efficiency and precision. It is these advantages of linear motors that are of great significance to pr...
