A linkage self-locking automobile wheel hub fixing device

Abstract

The invention discloses a linkage self-locking type car hub fixing device. The device comprises a first rod body, a second rod body, a driving mechanism, a supporting platform, a first clamping jaw and a second clamping jaw, wherein the first rod body and the second rod body are arranged in a crossed mode, the driving mechanism is used for driving the first rod body and the second rod body to rotate, and the supporting platform is used for supporting a hub. According to the linkage self-locking type car hub fixing device, a first thread part and a second thread part are arranged on the first rod body and the second rod body correspondingly, the thread rotation directions of the first thread part and the second thread part are opposite, the supporting platform is located between the first thread part and the second thread part, and the first clamping jaw and the second clamping jaw are matched with the first thread part and the second thread part in a threaded mode correspondingly, so that when the first rod body and the second rod body rotate, the first clamping jaw and the second clamping jaw simultaneously move towards the supporting platform so as to clamp and fix the hub placed on the supporting platform. The device is simple and compact in structure, good retaining and locking capacities are achieved, the clamping jaws cannot be loosened, and clamping is steady and firm.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing equipment, in particular to a linkage and self-locking automobile wheel hub fixing device. Background technique [0002] The wheel hub is a cylindrical metal part that is centered on the shaft in a car tire and is used to support the tire. It is an important part that connects the brake disc, wheel disc and half shaft. The fixing fixture is one of the necessary auxiliary tools for processing the wheel hub. In the fixing device for processing the wheel hub disclosed in the prior art, there is no linkage between the clamping points, and during the processing, the clamping parts are prone to loosening due to the influence of vibration. Causes the problem that the clamping is not firm and affects the machining accuracy. Contents of the invention [0003] Based on the technical problems existing in the above-mentioned background technology, the present invention proposes a linkag...
