Cylindrical workpiece spring clamping device used for linear cutting

Abstract

The invention discloses a cylindrical workpiece spring clamping device used for linear cutting. The cylindrical workpiece spring clamping device comprises a base plate, a V-shaped groove cushion table, a sliding pressing head, unthreaded rods, a pressure spring and a T-shaped pull rod. A cushion table support and a pull rod support are fixedly installed at the two ends of the upper side of the base plate correspondingly. The two unthreaded rods are fixedly installed between the cushion table support and the pull rod support. The V-shaped groove cushion table is fixedly installed on the inner side of the upper end of the cushion table support. The sliding pressing head is slidably installed on the two unthreaded rods. The T-shaped pull rod is slidably installed in the middle of the pull rod support through an unthreaded hole. The end of the T-shaped pull rod is fixedly connected with the sliding pressing head. The portion, located between the sliding pressing head and the pull rod support, of the T-shaped pull rod is sleeved with the pressure spring. The cylindrical workpiece spring clamping device has the following characteristics that the design is reasonable, the structure is simple, the machining accuracy is high, the workpiece assembling and disassembling efficiency is high, the labor intensity of workers is low, maintenance is easy, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of machining and relates to a clamp, in particular to a clamping device used for machining a cylindrical workpiece by a wire cutting machine. Background technique [0002] The wire-cut electric discharge machine was invented in the Soviet Union in 1960. Because the wire-cutting process is suitable for the processing of high hardness, difficult-to-machine materials and complex cavities, it plays a very important role in manufacturing, especially mold processing. When using a wire cutting machine to process a thin-walled cylinder, it is necessary to use a clamping device to tighten the thin-walled cylinder. At that time, because the thin-walled cylinder had the characteristics of thin wall, poor rigidity and weak strength, it was easily deformed during the clamping process. As a result, the accuracy requirements of its dimensional accuracy and geometric tolerance are affected. SUMMARY OF THE INVENTION [00...
