Abstract

The invention discloses a quick centering fixture for a tyre. The quick centering fixture comprises a fixture main body assembly, a gear and rack driving mechanism, and a locking mechanism, wherein the fixture main body assembly comprises a seat body and three guiding rails outwards extending, a sliding seat is configured on each guiding rail, and a clamping claw used for clamping the tyre is fixed on each sliding seat; the gear and rack driving mechanism comprises three racks, one end of each rack is fixedly connected with the corresponding sliding seat and parallel to the reverse direction of the corresponding guiding rail, a center shaft sleeve is mounted in the seat body, a gear is fixed on the center shaft sleeve, and each of the three racks are meshed with the gear for transmission;and the locking mechanism comprises a ratchet, a positioning pin rod and a positioning pin telescopic member, the ratchet is fixed on the center shaft sleeve, and the positioning pin telescopic memberdrives the positioning pin rod to be engaged or separated from the ratchet. The quick centering fixture adopts the gear and rack driving mechanism, the regulating stroke of the fixture can be improved, the adjusting speed is high, and the working efficiency is improved; and the locking mechanism can quickly control the rotation direction of the gear and rack driving mechanism and the corresponding clamping claw during the working, rotating in one direction is achieved, and the safety is improved.

Description

technical field [0001] The invention belongs to the technical field of angle measurement of automobile wheels, and in particular relates to a quick centering fixture for tires. Background technique [0002] The wheel fast center positioning fixtures on the market mainly include four-point fixtures and three-point fixtures. The clamping methods include screw form, 3-point or ring positioning, two-claw tire-holding clamping and three-claw tire-holding. Since the vast majority of vehicles now use aluminum alloy wheels or wheel decoration covers, in order to ensure that the decoration of the wheel surface is not damaged during maintenance, more and more customers use the three-claw grip tire clamp. At present, most of the clamps with three claws holding the tire adopt the crank connecting rod transmission method to ensure the synchronous centering of the three claws. The worm and worm method ensures locking or the screw method is used for locking. The stroke is small, the adju...
