A hub clamping mechanism

Abstract

The invention discloses a wheel hub clamping mechanism, which relates to the technical field of wheel hub processing, and comprises a fixing part, a bearing plate, a plurality of sliding rods, a rotating plate, a first elastic unit and a loose assembly, wherein the bearing plate is arranged on the fixing part, The end surface of the bearing plate is provided with a plurality of guide grooves in the radial direction; the rotating plate and the carrying plate are coaxially arranged, and the two can rotate relative to each other. There are multiple inclined guide parts on the rotating plate; the tops of the sliding rods are fixedly connected There is a clamping head, and each sliding rod, each guiding portion and each guiding groove are grouped in one-to-one correspondence, and the sliding rod in each group is slidably connected to the corresponding guiding portion and guiding groove at the same time. In the present invention, the loose assembly can keep the clamping heads apart, so that there is a distance between the adjacent clamping heads that is greater than the width of the spokes, which is convenient for placing the wheel hub, unfastening the loose assembly, and the elastic force of the first elastic unit drives the rotating disk to rotate , through the sliding rod to drive the clamping heads to slide and close synchronously to clamp and fix the hub.

Description

technical field [0001] The invention relates to the technical field of wheel hub processing, in particular to a wheel hub clamping mechanism. Background technique [0002] The wheel hub is the rotating part of the wheel core connected by the inner profile steel of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft. In the industry, for small-diameter wheels such as two-wheeled electric vehicles and balance vehicles, the parts other than the tires are also collectively referred to as hubs. The hub is a rigid wheel that fixes the inner edge of the tire, supports the tire and bears the load together with the tire. The rim is the part that is assembled with the tire and directly supports the tire. The spoke is the part that is installed and connected with the axle hub and supports the rim; the central axis is the part of the wheel. The wheel rim is connected to the wheel core rotating part through the spokes, an...

Problems solved by technology

[0004] In the prior art, the clamping operation of the wheel hub is very inconvenient. Before fixing the wheel hub, the wheel hub needs to be placed on the fixed position of the fixing device very accurately, and the angle of the spokes must be taken into account, which requires a lot of labor for the operator. In addition, there are often inaccurate situations, which lead to unstable fixation or need to be relocated, making it inconvenient to clamp the hub. On the assembly line that needs to process a large number of hubs, the accumulation of a small amount will greatly affect the overall processing. Progress, production efficiency is difficult to improve
