Description

Gear drives puncher

Technical field

Punch device is the utility model is related to, more particularly to a kind of gear driving puncher.

Background technology

In production process of today, increasing product is required for carrying out a series of punching processings, will Puncher for processing spare and accessory parts is equipped with pliers to keep and move the processed spare and accessory parts on table surface.This A little pliers are installed on a Horizontal dividing baseline rod in such a way, and these pliers positions are according to processing spare and accessory parts Size and determined with adapting to different demands, and in punch operation, the drift carried in machine tool will not be with These pliers disturb.

Index lever can move on the working face of puncher along two-dimensional direction, so that the plate still kept by pliers is presented To the machine tool carried by drift, the task by dominating and controlling each puncher is so just able to carry out.The hand of pliers Dynamic positioning action need to take much time, and can have a strong impact on the production efficiency of puncher, and thus also by influence product into This.

Utility model content

To solve above technical problem, the utility model provides a kind of gear driving puncher, to solve using fixed manually Position punching, efficiency is low, and the accuracy that it is punched is inadequate, it may appear that the problems such as larger error.

The technical solution adopted in the utility model is as follows：A kind of gear drives puncher, it is characterised in that：Including drift and The knife rest of the drift is supported, the knife rest is horizontally disposed with, and tool rest bracket, the tool rest bracket and institute are provided with below the knife rest Knife rest is stated to connect by knife rest lowering or hoisting gear；

The knife rest includes main rotary shaft and the second secondary rotary shaft, consolidates respectively on the main rotary shaft and the second secondary rotary shaft Driving gear and the second driven gear are cased with, second driven gear engages with the driving gear, the described second secondary rotation The bottom of axle connects the drift；

The knife rest lowering or hoisting gear includes the lead screw motor that Z-direction is set, and the ball screw Z-direction of the lead screw motor is stretched out, Screw thread is equipped with pilot sleeve on the ball screw of the lead screw motor, and the base of the lead screw motor is consolidated with the tool rest bracket Fixed connection, the top of the pilot sleeve are fixedly connected by knife rest support member with the knife rest, the second secondary rotary shaft Bottom is connected by the rotating shaft connecting rod with the drift.

The beneficial effect of above scheme is the height that knife rest lowering or hoisting gear can adjust knife rest as needed, and drift then can be with The adjustment angle in the presence of main rotary shaft and the second secondary rotary shaft, so as to quickly determine the position of required drilling, improve and bore The accuracy and accuracy in hole.

Preferably, the knife rest support member includes two rotary shaft mounting discs that upper and lower face is set, and described second is driven Gear and the driving gear are respectively positioned between two rotary shaft mounting discs, the top of the main rotary shaft and the second secondary rotary shaft It is arranged on by bearing in the rotary shaft mounting disc, the top of two rotary shaft mounting discs and the pilot sleeve, which is fixed, to be connected Connect.The effect of the program is the position that rotary shaft mounting disc secures driving gear and driven gear, support fixed gear with from Moving gear, which cooperates, makees gear motion, and rotary shaft is arranged in mounting disc by bearing, avoids rotary shaft in operation process Middle situations such as swinging, improve the stability for adding rotary shaft in rotation process.

Preferably, the drift is fixedly connected with the described second secondary rotary shaft by knife rest connecting rod.The effect of the program Be drift can under the drive of the second secondary rotary shaft adjustment angle.

Preferably, the upper end stretching rotary shaft mounting disc of the main rotary shaft is connected with motor.

Beneficial effect：Compared with prior art, gear driving puncher provided by the utility model, clever structure, operation Simply, using effect is good, service life length, height, the anglec of rotation of drift can be adjusted, and is matched somebody with somebody with adapting to be processed zero Part can effectively improve the machining accuracy for processing spare and accessory parts to hole depth, the requirement of gradient.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model Mode is applied to elaborate to the utility model.

A kind of as shown in figure 1, gear driving puncher, it is characterised in that：Knife including drift 1 and the support drift 1 Frame, the knife rest are horizontally disposed with, and are provided with tool rest bracket 2 below the knife rest, the tool rest bracket 2 and the knife rest pass through knife rest Lowering or hoisting gear connects；

The knife rest includes main rotary shaft a1 and second secondary rotary shaft a3, the secondary rotary shaft a3 of main rotary shaft a1 and second Upper to be installed with driving gear c1 and the second driven gear c3 respectively, the second driven gear c3 nibbles with the driving gear c1 Close, the drift 1 is fixedly connected with the described second secondary rotary shaft a3 by knife rest connecting rod d6；

The knife rest lowering or hoisting gear includes the lead screw motor d1 that Z-direction is set, and the ball screw Z-direction of the lead screw motor d1 is stretched Go out, screw thread is equipped with pilot sleeve d2 on the ball screw of the lead screw motor d1, the base of the lead screw motor d1 with it is described Tool rest bracket 2 is fixedly connected, and the top of the pilot sleeve d2 is fixedly connected by knife rest support member with the knife rest, and described Second mate's rotary shaft a3 bottom is connected by the rotating shaft connecting rod d6 with the drift 1.
