Rotary jig arm clamping device for workpiece processing

Abstract

The invention discloses a rotary type clamping arm clamping device for workpiece machining. The rotary type clamping arm clamping device comprises piston rods, a rotating shaft, a fixed seat plate, a rotating platform, clamping claws and a positioning pin, wherein the rotating platform is of a disk-like structure; a middle fixed seat is mounted at the circle center of the upper end of the rotating platform; the positioning pin is arranged at the middle part of the middle fixed seat; a rotating motor is mounted at the center of the upper end of the fixed seat plate; the upper end of the rotating motor is connected with the rotating shaft; the top of the rotating shaft is connected with the rotating platform; a plurality of movable holes which run through from top to bottom are formed in the rotating platform; shaft pins are mounted in the movable holes; the shaft pins are connected with clamping arms; the clamping claws are arranged at the upper ends of the clamping arms; female tenons are arranged at the bottom ends of the clamping arms, and are connected with male tenons; the male tenons are connected with pushing blocks; the inner sides of the pushing blocks are hinged with the piston rods. The rotary type clamping arm clamping device for workpiece machining can realize location, clamping and fixing of a workpiece, is firm and reliable in fixing, and is convenient for lateral machining of the workpiece; the operation time is saved, and the production efficiency is improved.

[0002] In the field of automobile production or lathe processing, for different processing methods such as drilling, welding, reaming and other processing methods on the surface of tubular workpieces, it is necessary to fix the workpiece first, especially during the processing of cylindrical workpieces, what are the conventional fixing methods? Stable, usually fixed and processed by hand, the processing quality and safety are difficult to guarantee, and the processing efficiency is also low

When the clamp is used for clamping, people need to manually tighten or press the clamp vigorously. The operation is complicated, the assembly efficiency is low, time-consuming and laborious, and when the workpiece needs to be processed at different positions, it needs to be reassembled to adjust the workpiece position, which is not suitable for the production and processing of the workpiece.
