Twin-spindle numerical-control device used for composite sliding block machining

Abstract

The invention discloses a twin-spindle numerical-control device used for composite sliding block machining. The device comprises a base. An X shaft, a Y shaft, first Z shaft supporting seats and second Z shaft supporting seats are installed on the base. An X shaft linear workbench, a Y shaft linear workbench, a first Z shaft linear workbench and a second Z shaft linear workbench are installed on the X shaft, the Y shaft, the first Z shaft supporting seats and the second Z shaft supporting seats respectively. A Y shaft supporting seat is fixedly installed on the X shaft linear workbench. The movement direction of the Y shaft linear workbench is perpendicular to that of the X shaft linear workbench. A first spindle machining mechanism and a second spindle machining mechanism which are opposite to each other are arranged on the first Z shaft linear workbench and the second Z shaft linear workbench respectively. A workpiece clamping seat is installed on the Y shaft linear workbench. According to the composite sliding block machining device, the first spindle machining mechanism and the second spindle machining mechanism which are opposite to each other can be adopted to machine sliding block ball return holes, threaded holes and chamfers in the two end faces of a sliding block at the same time, the machining efficiency is greatly improved, and the defect that the symmetry is poor due to the fact that clamping is conducted twice is overcome; the machining accuracy is improved, production cost is reduced easily, and the product reject ratio is decreased easily.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to a processing device for a guide rail auxiliary slider. Background technique [0002] In the production process of the auxiliary slider of the guide rail, it is necessary to carry out different mechanical processing on the end surface of the slider, including the ball return hole, threaded hole and chamfering processing of the slider. In the prior art, to carry out the above-mentioned processing, some use a variety of mechanical processing equipment and workers to cooperate, the processing efficiency is low and the quality is poor, and some use a general-purpose processing center plus a fourth-axis turntable fixture to cooperate, the processing efficiency is low and the production cost is low. high. Moreover, in the drilling process of the slider, the above-mentioned processing methods are to process one end face first and then the other end face. It is difficult to control th...

In the prior art, to carry out the above-mentioned processing, some use a variety of mechanical processing equipment and workers to cooperate, the processing efficiency is low and the quality is poor, and some use a general-purpose processing center plus a fourth-axis turntable fixture to cooperate, the processing efficiency is low and the production cost is low. high

Moreover, in the drilling process of the slider, the above-mentioned processing methods are to process one end face first and then the other end face. It is difficult to control the symmetry of the processing, and the factors of manual clamping and adjustment are greatly affected, resulting in a high defect rate of the product.
