Bent tube frock clamp

Abstract

The invention discloses a bent tube frock clamp which comprises a clamp base. A connecting piece is arranged under the clamp base. Sliding rails are arranged on the clamp base. A plurality of rectangular sliding pieces are arranged on the sliding rails. A sliding bar is arranged in the front portion of each rectangular sliding piece. A fixing piece is arranged on the rear portion of each rectangular sliding piece. A clamping device is arranged on each sliding bar and comprises a sliding groove, a turnplate and a bent tube fixing plate, wherein the lower portion of the turnplate is rotationally connected with the upper portion of the sliding groove, the upper portion of the turnplate is fixedly connected with the bent tube fixing plate, an arc-shaped through hole is formed in the bent tube fixing plate, and a locking device is further arranged between the turnplate and the sliding groove. According to the frock clamp provided by the invention, clamping is convenient, stable and reliable, the frock clamp is applicable to bent tubes of different radians and sizes, and the machining efficiency and machining precision of the bent tubes can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of workshop fixture equipment, and more specifically, relates to a tooling fixture for bent pipe parts. Background technique [0002] Fixtures are devices used to quickly fasten workpieces so that the props on the machine tool and the workpiece maintain the correct relative position. In order to make the surface of the workpiece meet the technical requirements such as the size, geometry and position accuracy of other surfaces specified in the drawings, processing The workpiece must be clamped and stabilized beforehand. Among them, the bent pipe has a special shape and the bending arcs are also different. Ordinary tooling fixtures cannot meet the processing requirements, which affects the processing efficiency and causes processing accuracy errors. Contents of the invention [0003] The object of the present invention is to provide a tooling fixture for bent pipe fittings, which is convenient to clamp, stab...
