Simultaneous moving bidirectional oil pressure chuck device and dual-machining system with same power source

Abstract

The invention discloses a simultaneous moving bidirectional oil pressure chuck device and a dual-machining system with the same power source. The simultaneous moving bidirectional oil pressure chuck device comprises an engine base, a fixing seat, a connection seat, a transmission part, a cylinder pressing unit, a front chuck unit and a rear chuck unit; the cylinder pressing unit is provided with a cylinder body sleeve connected with the connection seat and a driving ring moving relative to the cylinder body sleeve; the front chuck unit is provided with a front drum clamp and a front connection pipe; the rear chuck unit is provided with a rear drum clamp and a linkage assembly; the front drum clamp and the rear drum clamp can move between a loosening position and a clamping position relative to a front shaft cover and a rest shaft cover respectively. The dual-machining system with the same power source comprises a rack, the simultaneous moving bidirectional oil pressure chuck device and a machining device. The simultaneous moving bidirectional oil pressure chuck device and the dual-machining system with the same power source can synchronously act and clamp workpieces of different sizes, so the stability and convenience in clamping are improved.

Description

technical field [0001] The invention relates to a machine tool chuck, in particular to a co-moving two-way hydraulic chuck device and a same power source double processing system with the co-moving bi-directional hydraulic chuck device. Background technique [0002] refer to figure 1 , which is the No. 201130596 "Oil Hydraulic Chuck" Taiwan Invention Application, which the applicant has previously applied for and published. A fixed seat 40, a hydraulic cylinder 50, an internal positioning unit 60, a bearing unit 70, a connecting seat 80, a first oil circuit control unit 90, a second oil circuit control unit 95, and a brake seat 100 , a transmission member 110, a pull rod 120, a front axle cover 130, a rear axle cover 140, a front collet 150, a rear collet 160, a front end cover 170, and a rear end cover 180. Wherein, when the oil pressure is injected from a fourth oil hole 45 of the fixed seat 40, the oil pressure will flow into a communication hole 89, and then push a dri...

Problems solved by technology

In this way, during the clamping action, the rear collet 160 is bound to be affected by the interlocking connection of the tie rod 120 and slightly moves toward the front collet 150 in the direction of an axis L. This phenomenon easily leads to clamping accuracy On the other hand, because the pull rod 120 is used to make the front collet 150 and the rear collet 160 link to produce an open and close state, so that the front collet 150 and the rear collet 160 open and close the same degree, if when the front collet 150 and the rear collet 160 clamp a workpiece (not shown) with non-uniform outer diameter at the same time, as long as the front collet 150 and the rear collet 160 One of them clamps the workpiece first, and one of the collets will inevitably fail to clamp the workpiece, resulting in the workpiece not achieving the effect of two-point clamping. In this way, when the hydraulic chuck is running at high speed, then It will cause the workpiece to shake, which will affect the accuracy of processing. Another disadvantage is that the opening and closing of the front collet 150 and the rear collet 160 of the hydraulic chuck are the same, so they cannot be clamped synchronously. It can support workpieces of different sizes, and it is less adaptable and convenient in use.
