Description

Technical Field

[0001] The utility model belongs to the technical field of plastic parts processing, and in particular relates to a fixing clamping device used for plastic parts processing. Background Art

[0002] Plastic parts are widely used. Before use, plastic parts often need to be further processed into shapes that meet the requirements, such as grinding burrs, chamfering, and fine-cutting slots. At present, when processing the surface of plastic parts, the plastic parts need to be fixed and clamped before processing. Due to the different specifications of plastic parts when fixing the plastic parts, the existing fixing and clamping is prone to loose fixation after the plastic parts are fixed, causing the plastic parts to have positional displacement during the processing. This is not only inefficient, but also easily leads to a low plastic product qualification rate and a high scrap rate, which is not conducive to production cost control.

[0003] Therefore, developing a clamping device suitable for plastic parts processing is the key to solving the problem. Utility Model Content

[0006] Furthermore, the four corners of the workbench are respectively provided with limiting mechanisms, which include a support, a limiting plate, and a spring. The supports are respectively fixedly provided at the four corners of the workbench, and a limiting plate is provided on the inner side of the support, and each limiting plate points to the center of the workbench.

[0009] Furthermore, an air bag is arranged on the inner side of the splint, and the air bag is connected to the air source through a flexible air pipe.

[0010] The beneficial effects of the utility model are as follows: the utility model has a compact structure and is easy to use and operate. It can quickly limit and clamp plastic parts, and adopts air bags to adapt to the clamping and fixing needs of plastic parts of different sizes, shapes and specifications in a flexible clamping and fixing manner, thereby further improving stability and avoiding the situation where brute force clamping causes damage to the surface of plastic parts.
