Special fixture for machining the round cap of special-shaped integrated parts

Abstract

The invention discloses a special machining fixture for round caps of special-shaped integrated components. The special machining fixture comprises a flat cylindrical fixture body, a positioning block, a balance bolt and a balance block. The positioning block, the balance bolt and the balance block are arranged on the upper surface of the fixture body, the positioning block and the balance block are respectively arranged on the left side and the right side of the balance bolt, a workpiece round cap accommodating station is formed between the positioning block and the balance block, the balance bolt is arranged in the middle of the upper surface of the fixture body and corresponds to a boss of a workpiece round cap, the positioning block comprises a block-shaped body, a workpiece shaft positioning hole and a seam, the workpiece shaft positioning hole is perforated through the block-shaped body in the left-right direction, the seam is perforated through the rear side surface of the workpiece shaft positioning hole and the rear side surface of the block-shaped body, a clamping screw hole which is perpendicularly perforated through the seam is formed in the block-shaped body, and a clamping bolt is arranged in the clamping screw hole. The special machining fixture has the advantages that the special machining fixture is reasonable and simple in structure, low in cost, high in clamping force, easy to maintain in follow-up procedures and applicable to large-scale production, and brings convenience for clamping operation, to-be-machined workpieces can be quickly clamped by the special machining fixture, machined workpieces are dimensionally stable and reliable, and the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to a special fixture for machining the round cap of a special-shaped integrated part, which is used for clamping the workpiece during the process of machining the special-shaped integrated part. Background technique [0002] Such as image 3 , Figure 4 As shown, the special-shaped integrated part is composed of a cylindrical shaft part 12 and a round cap part 13 positioned at the side of the shaft part 12. The upper end surface of the round cap part 13 is an arc surface, and the lower end surface of the round cap part 13 is provided with two A circular boss 14. When machining the arc-shaped surface of the round cap portion of the special-shaped integrated part, the shaft portion 12 of the workpiece needs to be clamped in the fixture, and the arc-shaped surface of the round cap portion 13 is exposed to facilitate processing. [0003] However, the existing fixtures used here have complex structures, high cost of the fixture itsel...

Problems solved by technology

[0003] However, the existing fixtures used here have complex structures, high cost of the fixture itself, inconvenient clamping, slow workpiece clamping speed, insufficient clamping force, unstable workpiece dimensions after processing, and are not suitable for mass production and production. The disadvantage of high cost, the structure of the existing fixture used here is not reasonable enough, and needs to be further improved
