Pneumatic chucking tool capable of milling two faces of track link section piece

Abstract

The invention discloses a pneumatic chucking tool capable of milling two faces of a track link section piece. The pneumatic chucking tool comprises positioning pins 2 and a screw 1, wherein the positioning pins 2 are arranged on a positioning base 6 and located at the upper portion of the pneumatic chucking tool and the lower portion of the positioning base 6 respectively, and the screw 1 is arranged in the middle of the positioning base 6 and used for penetrating the track link section piece to be machined. The front end of the screw 1 penetrates through an L-shaped pressing plate 4 and is then connected with a nut 5 in a rotating mode. The rear end of the screw 1 is hinged to the middle of a lever 7. The lower end of the lever 7 is fixedly hinged to the positioning base 6. The upper end of the lever 7 is hinged to one end of a piston rod 9. A telescopic unit is arranged at the rear portion of the piston rod 9. By means of the pneumatic chucking tool, pressing is conducted according to the principle that the lever is pushed through three hinge points and an air cylinder, labor intensity is greatly lowered, and work efficiency is improved by more than one time; meanwhile, electricity is saved for an enterprise, losses are reduced, chucking can be conveniently conducted and is more stable compared with manual chucking, and product quality is guaranteed.

Description

technical field [0001] The present invention relates to a fixture device, more specifically, to a fixture used for milling double sides in chain rail segment processing. Background technique [0002] Crawler-type traveling mechanisms are widely used in construction machinery, and most of them work in harsh environments such as ore mining and construction excavation. Therefore, there are strict requirements for the processing of their parts. [0003] Tracks and chains are an integral part of crawler-type traveling mechanisms such as bulldozers and excavators. However, the most important part of the track and chain is the segment, which plays a vital role in the normal operation of the crawler. However, machining chain rail segments is often difficult. [0004] Such as figure 1 As shown, two surfaces need to be processed to process chain rail segments, that is, two surfaces A and B, but the clamping process is relatively difficult, and workers need to use double-sided milli...
