Problems solved by technology

Therefore, when the automobile hub is running at high speed in its working state, in order to ensure the safety of the running car, there are high requirements for the strength and roundness of the wheel hub, otherwise there will be great safety hazards, and automobile driving accidents will occur.
[0003] Therefore, in the process of processing automobile wheels, tightening tooling is one of the necessary auxiliary tools for processing automobile wheels. To achieve accurate clamping, positioning and pressing is a necessary condition to ensure the roundness of automobile wheels and an important factor in wheel processing; , the traditional t

Abstract

The invention patent discloses an automobile hub clamping fixture with an automatic centering function, and belongs to the technical field of clamping fixtures. The automobile hub clamping fixture comprises a machine body and a rotary worktable arranged above the machine body; a PLC (Programmable Logic Controller) control unit and an electric control unit for driving the rotary worktable to rotate are arranged in the machine body; a pneumatic expansion shaft is fixedly arranged at the center of the rotary worktable; circumferentially uniformly distributed pneumatic blocks are arranged on the pneumatic expansion shaft; radially uniformly distributed positioning slots are arranged on the upper surface of the rotary worktable; a pressing module is arranged on the positioning slot; and the pneumatic expansion shaft and the pressing module are both connected with the PLC control unit. The automobile hub clamping fixture disclosed by the invention is simple in structure, reasonable in design, strong in university, and wide in applicable range. The automatic centering positioning can be realized, the processing efficiency of the product is greatly improved, the processing period is shortened, and the processing cost is saved.

Description

technical field [0001] The invention relates to the technical field of tooling for processing auto parts, in particular to an automotive hub clamping tool with an automatic centering function. Background technique [0002] The wheel hub is also called the rim, the wheel, and the tire bell. It is a barrel-shaped, center-mounted metal part that supports the tire on the inner profile of the tire. The wheel hub is an important driving part of the car, which bears most of the load generated during the driving process of the car. Therefore, the structure of the wheel hub affects the performance of the car to a large extent. Therefore, when the working state of the automobile hub is running at high speed, in order to ensure the safety of the running car, there are high requirements for the strength and roundness of the wheel hub, otherwise there will be great safety hazards and automobile driving accidents. [0003] Therefore, in the process of processing automobile wheels, tighte...
