Pneumatic rapid clamping device

Abstract

The invention relates to a pneumatic rapid clamping device which comprises a bottom plate, side plates, a rear back plate, an air cylinder and an ejector block. The two side plates are arranged on theupper surface of the bottom plate; the rear back plate is arranged on the bottom plate behind the two side plates; the air cylinder is arranged on the rear back plate; a piston rod of the air cylinder penetrates through the rear back plate; a wedge block is arranged at the front end of the piston rod and is located between the two side plates; a horizontal positioning pin rod is arranged on the lower part of the inner side wall of the left side plate; the ejector block is arranged on the upper part of the inner side wall of the left side plate; the ejector block and the wedge block are in diagonal-face contact; a hard spot positioning block is arranged on the upper part of the inner side wall of the left side plate; and a workpiece clamping area is formed between the hard spot positioningblock and the front part of the ejector block. The pneumatic rapid clamping device has a reasonable structure and a high automation degree; and by utilizing the device, the processing accuracy of a workpiece is improved, the processing speed is accelerated, the production cost is reduced, and the labor intensity of working personnel is reduced.

Description

technical field [0001] The invention relates to a clamping tool in the technical field of automobile engine pawl processing, in particular to a pneumatic fast clamping device. Background technique [0002] Such as Figure 5 As shown, the automobile engine pawl is a part with a relatively special shape. Its shape is irregular, and the surface has many curved surfaces, bosses and slopes, etc., and there are many parts that need to be processed. At present, when processing the top groove at the back of the pawl, since there is no special clamping tool, common tools such as ordinary pressure plates can only be used for simple fixing, and the matching degree between the workpiece and the clamping tool is low, resulting in low clamping accuracy 1. The processing accuracy of the product is low, and rework is often required, and even the workpiece is directly scrapped, resulting in an increase in the production cost of the enterprise and a decrease in work efficiency. Therefore, th...
