Abstract

The invention provides an improved type reinforcing screw rod type heavy-duty four-jaw independent chuck, which can realize reasonable selection of workpiece clamping force under different working requirements and solve the problem of insufficient clamping force when loaded with a heavy type workpiece. The improved type reinforcing screw rod type heavy-duty four-jaw independent chuck comprises a chuck body, a pressure block, four jaws and screw rods, wherein the pressure block is positioned on a central position on the surface at one end of the chuck body; and one end of the chuck body is provided with the four jaws. The improved type reinforcing screw rod type heavy-duty four-jaw independent chuck is characterized in that the screw rods are reinforcing screw rods; the four jaws are connected with corresponding reinforcing screw rods respectively; and the reinforcing screw rods are supported on the chuck body.

Description

(1) Technical field [0001] The invention relates to tooling for mechanical processing, in particular to an improved force-increasing lead screw type heavy-duty four-jaw single-action chuck. (2) Background technology [0002] The clamping force of the existing four-jaw single-action chuck is not large enough, especially when clamping large-scale and heavy workpieces. When holding the workpiece, due to simply relying on the workers to clamp through the wrench, the labor intensity is high. (3) Contents of the invention [0003] In view of the above problems, the present invention provides an improved force-increased lead screw type heavy-duty four-jaw single-action chuck, which can realize the reasonable selection of workpiece clamping force under different work requirements, and solve the problem of insufficient clamping force when carrying heavy workpieces. The problem. [0004] Its technical solution is as follows: it includes a disc body, a pressing block, four claws, a...
