Problems solved by technology

[0003] When the existing hub clamping mechanism clamps the hub, the moving process of its claws is unstable when they are facing each other synchronously or away from each other. It is often easy for multiple claws to clamp on the surface of the hub one after another. It is subtle and difficult to detect, but it will cause the clamping center of the hook to be out of axis with the hub circle center, which will affect the machining accuracy of the hub

Abstract

The invention discloses a hub concentric clamping mechanism, and relates to the field of hub machining, the hub concentric clamping mechanism comprises a cam lifting plate located on the upper portion and a cam rear plate arranged on the lower side of the cam lifting plate, a cam front plate is arranged on the lower side of the cam rear plate, and at least three sets of claw hooks are arranged on the lower side of the cam front plate; the multiple sets of claw hooks are arranged in an equal-angle radial mode with the center of the cam front plate as the center, transmission structures are arranged on the cam rear plate and the cam front plate, and the transmission structures are used for achieving synchronous movement of the multiple sets of claw hooks in the direction away from or close to the center of the cam front plate. When the claw hooks move towards the center of the cam front plate, the hub can be clamped at the moment, and due to the fact that each set of claw hooks synchronously advance, the time for each set of claw hooks to reach the inner ring face of the hub is the same, the hub can be positioned and clamped at a time, follow-up adjustment is not needed, and the machining efficiency of the hub is greatly improved.

Description

technical field [0001] The invention relates to the field of hub processing, in particular to a hub concentric clamping mechanism. Background technique [0002] The hub is an intermediate component that fixes the tire and connects the tire to the axle. After continuous improvement, under the conditions of modern industrial technology, the wheel hub has become a fully functional integral component. In the production of the wheel hub, it is generally necessary to go through the wheel hub blank for many times, milling and cutting with various lathes to make the wheel hub preliminary shape, and the wheel hub needs to be clamped many times during the processing process. [0003] When the existing hub clamping mechanism clamps the hub, the moving process of its claws is unstable when they are facing each other synchronously or away from each other. It is often easy for multiple claws to clamp on the surface of the hub one after another. It is subtle and difficult to detect, but ...
