Plastic gear rack transmission device for mechanical arm

Abstract

A plastic gear rack transmission device for a mechanical arm is used for the reciprocating motion of a mechanical arm slide arm of a knockout machine. A motor is fixed to a speed reducer, a drive gear is in shaft connection with the speed reducer, the speed reducer is arranged on a speed reducer fixing plate, the speed reducer fixing plate is connected with a unit support, a guide rail is arranged on the left side face of the slide arm, sliding blocks are arranged on the unit support, the sliding blocks are fixedly locked with the guide rail, a plastic gear rack moulded in an injection mode is assembled parallel to the guide rail on the left side face of the slide arm, the plastic gear rack is of a two-side symmetric structure, the drive gear is meshed with the plastic gear rack, and the unit support is provided with an adjusting screw. The motor rotates to drive the drive gear to rotate, the drive gear rotates to drive the plastic gear rack to move, and each unit of the mechanical arm is made to carry out reciprocating motion under the matching action of a power device and a guide mechanism. Cost is greatly lowered, meanwhile, the defects that the mechanical arm of an existing knockout machine is heavy and high in transmission noise are overcome, and the plastic gear rack transmission device is simple in structure and production process, convenient to mount and maintain, light and low in transmission noise.

Description

technical field [0001] The invention relates to the technical field of industrial automation, in particular to a transmission device for a manipulator of a take-out machine, which uses a gear to drive a plastic rack to convert rotary motion into linear motion. Background technique [0002] At present, the transmission methods used by common take-out machine manipulators can be divided into the following two types: one is driven by a synchronous belt pulley, which is too cumbersome to install and adjust, and is inconvenient to disassemble and maintain; the other is made of iron The gear drives the iron rack to drive. This transmission method solves the problem of the former being too cumbersome to install and adjust, and it is inconvenient to disassemble and maintain. However, the iron rack has the disadvantages of large transmission noise and heavy weight, and it also cannot satisfy the light weight of modern take-out machine manipulators. , fast speed and low noise requirem...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of complex structure, bulky and high transmission noise of the existing take-out machine manipulator, the purpose of the invention is to provide a plastic rack gear for the manipulator, so as to realize the purpose of easy installation and maintenance, and low transmission noise

[0005] The present invention replaces the synchronous belt drive and the iron rack and pinion drive of the existing take-out machine manipulator with the plastic rack dr
