Problems solved by technology

Therefore, broaching is mainly used for mass production in batches; at present, for spline holes, round holes and keyways, etc., which need to be processed by broaching technology, various machinery manufacturing enterprises have been purchasing special broaching machines for processing or outsourcing production. However, the purchase of special machine tools requires more funds, which increases the cost of the enterprise; due to the different standards of each processing enterprise in outsourcing production, the quality of the produced workpieces will be different, which is not conducive to subsequent production

Embodiment Construction

[0019] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0020] As can be seen from the accompanying drawings, the broaching device for a lathe of this program includes a lathe support 20 and a lathe main shaft 4, the front support 7 is arranged at the lathe main shaft 4, and a rear support 13 is also fixed on the lathe support 20. The front bracket 7 is provided with a lead screw 8, and a first nut 1 engaged with the lead screw 8 is arranged. The first nut 1 is fixed on the lathe spindle 4, and the end of the lead screw 8 away from the first nut 1 is fixed. There is a broach chuck 14; the rear support 13 is provided with a positioning sleeve 19, and the outside of the positioning sleeve 19 is provided with a spherical ring 18, and the outside of the spherical ring 18 is provided with a spherical support 17. The positioning sleeve 19 is fi...

Abstract

The invention provides the technical scheme of a broaching device for a lathe. According to the technical scheme, the broaching device for the lathe comprises a lathe support and a lathe main shaft, wherein a front support is arranged on the lathe main shaft, a rear support is further fixed to the lathe support, a lead screw and a first nut which is meshed with the lead screw are arranged on the front support, the first nut is fixed to the lathe main shaft, a broach clamping head is fixed to the end, away from the first nut, of the lead screw, a positioning sleeve is arranged on the rear support, a spherical ring is arranged outside the positioning sleeve, and a spherical support is arranged outside the spherical ring. According to the technical scheme, the rotational motion of the lathe is converted into the linear reciprocating motion through lead screw connection so that the broaching function can be achieved, the lathe main shaft is guaranteed to output the torque and not to bear tension force through a positioning support and is guaranteed to be easy to detach, the broaching device is used for various ordinary lathes, and therefore the efficient broaching function is achieved.

Description

technical field [0001] The invention relates to a processing device, in particular to a broaching device for a lathe used for processing workpieces such as spline holes, round holes and key grooves. Background technique [0002] In the prior art, broaching is a cutting process using a broach as a tool. When the broach moves in a straight line relative to the workpiece, the machining allowance of the workpiece is cut off sequentially by the teeth on the broach with incrementally increasing sizes. Rough-semi-finishing-finishing can be completed in one working stroke, which greatly shortens the basic Process time and auxiliary time, is a high-efficiency finishing method. Therefore, broaching is mainly used for mass production in batches; at present, for spline holes, round holes and keyways, etc., which need to be processed by broaching technology, various machinery manufacturing enterprises have been purchasing special broaching machines for processing or outsourcing producti...
