Description

A machining center fixture

Technical Field

The utility model relates to the technical field of clamps, in particular to a machining center clamp.

Background Art

In the manufacturing of tire accessories for vehicles, the valve stem is a key component for maintaining stable tire pressure. Its processing quality and efficiency have a significant impact on the safety, performance and manufacturing cost of the vehicle. Traditionally, CNC lathes are generally used for valve stem processing, whether for automobiles or electric vehicles, but this processing method faces many challenges.

First of all, the single-piece processing mode of the CNC lathe greatly limits production efficiency. It can only clamp and process one valve at a time, causing the machine tool to be idle or in auxiliary operations such as tool changing and adjustment most of the time, thereby reducing the utilization rate of the overall production line.

Secondly, the clamping accuracy issue cannot be ignored. During high-frequency clamping processes, due to the operator's technical level, fluctuations in machine tool accuracy, and differences in workpiece materials, it is difficult to maintain consistent clamping accuracy. This will not only affect the valve processing accuracy, but may also increase the scrap rate and have an adverse effect on product quality.

Furthermore, with the popularization of electric vehicles, cars and other means of transportation, the market demand for accessories such as valve stems is also growing rapidly. The traditional CNC lathe single-piece processing method is unable to cope with large-scale and high-efficiency production needs and is unable to meet the rapidly changing market needs.

Based on this, the applicant proposed a machining center fixture to solve the above technical problems.
