A high-precision grinding machine double-tightening self-centering mechanism fixture and its grinding machine

Abstract

The invention discloses a high-precision grinding machine coupled twin tensioning self-centering mechanism fixture and a grinding machine thereof. The high-precision grinding machine coupled twin tensioning self-centering mechanism fixture comprises a fixture body provided with a step hole, a first auxiliary wedge-caulking mechanism and a second auxiliary wedge-caulking mechanism are arranged in the step hole, the second auxiliary wedge-caulking mechanism is slidably arranged on the outer side of the first auxiliary wedge-caulking mechanism in a sleeving mode, and the second auxiliary wedge-caulking mechanism is slidably mounted in the step hole in a matched mode. A first wedge-shaped tensioning block set, a second wedge-shaped tensioning block set and a workpiece tensioning sleeve are arranged on the fixture body, the first wedge-shaped tensioning block set is in wedge fit with the first auxiliary wedge-caulking mechanism, the second wedge-shaped tensioning block set is in wedge fit with the second auxiliary wedge-caulking mechanism, and the peripheral surfaces of the first wedge-shaped tensioning block set and the second wedge-shaped tensioning block set are matched with the inner wall of the workpiece tensioning sleeve. The high-procession grinding machine coupled twin tensioning self-centering mechanism fixture effectively achieves high-precision positioning and high efficiency production of the grinding machine, the risks of damage to equipment and workpieces caused by traditional power off, gas off and hydraulic off are effectively controlled, and self protection effects on the workpieces and the equipment are achieved through a fixture gas inspection device.

Description

technical field [0001] The invention relates to a high-precision grinding machine double-linkage tensioning self-centering mechanism fixture, which belongs to the technical field of high-precision grinding processing for grinding machines, and in particular relates to the application of a high-precision double-linkage tensioning self-centering clamping mechanism. Background technique [0002] In the automobile braking system, the matching and positioning design accuracy of the hub, the bearing and the brake disc are relatively high, and the matching surface area of ​​the hub and the bearing has high requirements for shape and position accuracy, which is a major problem in hub processing. The diamond roller is used to grind the forming grinding wheel to ensure the shape and position accuracy of the workpiece processing surface, which requires the workpiece to be accurately positioned in the grinding machine, and the stability of the workpiece during the grinding process and th...

Problems solved by technology

[0003] Although there are a variety of high-precision processing fixtures for grinding machines in the prior art, these fixtures are generally designed with elastic expansion sleeves, which have poor positioning accuracy, low efficiency, and short service life. Many unobjective factors are likely to cause damage to equipment and workpieces. damage, greatly prolonging the working hours and labor intensity of processing workers
