Spindle servo positioning transmission device during slot shaping machine machining

Abstract

The invention discloses a spindle servo positioning transmission device during slot shaping machine machining. The device comprises a table board, and a first linear guide rail and a second linear guide rail are arranged on the outer surface of the table board; a rack and a gear are arranged on one side of the first linear guide rail, and a drag chain is arranged on the other side of the first linear guide rail; and a translation supporting plate is arranged above the second linear guide rail, a lifting tool rest is arranged on the translation supporting plate, and a right-angle speed reducerand a servo motor are arranged on one side of the lifting tool rest. According to the spindle servo positioning transmission device during slot shaping machine machining, through the mode of bevel gear rack, shaking can be well avoided; meanwhile, bevel gear rack meshing is good so that the basic precision can be guaranteed; and meanwhile, the device is provided with three soft positions includinga translation left limit, a translation right limit and a translation original point and two mechanical hard limits so that repeated errors and extreme conditions occurring in the machining process can be avoided.

Description

technical field [0001] The invention relates to the technical field of planing machines, in particular to a spindle servo positioning transmission device in planing machine processing. Background technique [0002] The two most important transmission mechanisms for grooving processing are one for lifting and lowering, and the other for left and right movement; inaccurate left and right movements will also lead to inaccurate machining accuracy and even accidents; the general left and right movements on the market currently pass through long-distance ball wires. The ball screw with this structure has a large vibration and high operating noise. The ball screw is easily damaged by the shaving force of the board for a long time. Contents of the invention [0003] (1) Solved technical problems [0004] The main purpose of the present invention is to provide a spindle servo positioning transmission device in planing machining, which can effectively solve the problems in the back...

[0002] The two most important transmission mechanisms for grooving processing are one for lifting and lowering, and the other for left and right movement; inaccurate left and right movements will also lead to inaccurate machining accuracy and even accidents; the general left and right movements on the market currently pass through long-distance ball wires. The ball screw itself with this structure has a lot of jitter and high noise, and the ball screw is easily damaged by the shaving force of the board for a long time.
