Description

TECHNICAL FIELD

[0001] The utility model relates to metal clamp technical field especially relates to a metal surface treatment processing fixing clamp. BACKGROUND

[0002] In the metal surface treatment processing, the fixing clamp as the important tool of ensuring workpiece stability and machining precision, its function can not be ignored. However, the existing metal surface treatment processing fixing clamp when dealing with different shapes and sizes of workpiece, often show certain limitation, this not only affects the processing efficiency, also challenges the product quality.

[0003] The fixing clamp on the current market is designed for specific size and shape, lack enough flexibility to adapt to various types of workpiece. Although this special type of design can guarantee the clamping effect for specific workpiece to a certain extent, but once involving non-standard or special-shaped workpiece, its applicability is greatly discounted. Because unable to flexibly adjust the clamping position and force, these fixing clamps are difficult to meet the diversified production needs, leading enterprises to face complex orders must frequently change equipment or customize special clamps, increase cost and time consumption.

[0004] In actual operation, the fixing clamp is not flexible enough to clamp different shapes and sizes of workpiece. For those workpieces with complex geometric structure, the traditional clamp can not provide uniform and stable support, so that some parts are prone to looseness or deformation in the machining process. This not only affects the quality of the final product, but also may lead to the increase of scrap rate. In addition, due to the inability to accurately control the clamping force, too tight may damage the workpiece surface or even cause permanent damage, while too loose cannot ensure the stability of the workpiece in the whole machining process, thereby affecting the machining precision.

[0005] Another significant problem is that the existing fixing clamp has limited processing capacity for small workpieces. When facing small size and light weight parts, the traditional clamp either cannot be effectively positioned due to the excessive clamping area, or the workpiece is displaced due to uneven pressure distribution. This is particularly serious in the field of precision machining, and even a small positional deviation can cause irreparable quality loss. Moreover, when carrying out batch production, it is a time-consuming and laborious work to adjust the clamp parameters every time to adapt to the new workpiece shape and size, greatly reducing the overall efficiency of the production line.

[0006] Therefore, how to provide a metal surface treatment processing fixing clamp is a problem that the skilled in the art needs to solve. UTILITY MODEL CONTENT
