Embodiment Construction

[0043] The embodiment of the present invention provides an electrolytic machining machine tool with a large-lead multi-raceway ball nut arc spiral groove. By setting the hollow rotating platform and the XY precision slide table above the workbench, the cathode guide provided with the cathode ball head is driven. The rod performs electrolytic machining on the blank of the ball nut, which solves the problem of the rotation accuracy of the rotating shaft caused by placing the XY slide table or the rotating mechanism under the workbench and installing the workpiece on the rotating shaft drawn from the XY sliding table or rotating mechanism in the prior art. Technical problem with reduced sealing effect.

[0044] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings i...

Abstract

The embodiment of the invention discloses an electrolytic machining machine tool for a large-lead multi-roller-path rolling ball nut circular-arc spiral groove. A hollow rotary platform and an XY precise sliding table are arranged above a workbench; a cathode guide rod with a cathode ball head is driven to carry out electrolytic machining on a rolling ball nut semi-finished product piece, so that the technical problem that rotation precision and sealing effect of a rotary shaft are reduced due to the fact that the XY sliding table or a rotating mechanism is arranged under the workbench, and a workpiece is mounted on the rotary shaft which is guided out from the XY sliding table or the rotary mechanism in the prior art. According to the embodiment of the invention, the electrolytic machining machine tool comprises a machine tool body, an electrolyte circulating box, a power supply and a control cabinet.

Description

technical field [0001] The invention relates to the field of electrolytic machining, in particular to an electrolytic machining machine tool for arc spiral grooves of ball nuts with large leads and multiple raceways. Background technique [0002] The traditional processing technology of nut internal thread raceway is: 1. Rough turning nut raceway (with grinding allowance); 2. Nut quenching; 3. Internal thread grinder grinding nut raceway. With the development of mechanical products in the direction of high speed, high efficiency and automation, there are requirements for ball screw pairs with large lead, multiple raceways and high precision. Increase, the difficulty of manufacturing the internal thread raceway of the nut is greatly increased. With the traditional processing technology, the processing equipment is difficult to guarantee the accuracy, and it is easy to cause excessive errors. Therefore, the arc spiral groove of the large-lead multi-track ball nut is now electr...
