Cylindrical workpiece processing fixture

Abstract

The invention belongs to the technical field of mechanical part tools and fixtures, and particularly relates to a cylindrical workpiece processing fixture which comprises a rack, wherein the rack is of a frame structure; the cylindrical workpiece processing fixture is characterized by further comprising two V-shaped clamping jaws, a top clamping jaw used for applying a force on the top of the cylindrical workpiece, bottom drivers, a top driver and a support; the V-shaped clamping jaws comprise clamping edges and driving edges; the clamping edges of the two V-shaped clamping jaws are mutually hinged; the driving edges of the two V-shaped clamping jaws are connected with the bottom drivers separately; the bottom drivers are connected with the rack; a sliding block is arranged at the included angle of each V-shaped clamping jaw; the sliding blocks are in sliding fit with an arc-shaped sliding groove formed in the support; the radius of the arc-shaped sliding groove is the same as the distance between the hinge point of the clamping edges of the V-shaped clamping jaws and the included angle of each V-shaped clamping jaw; the top clamping jaw is connected with the top driver; and the top driver is arranged at the top of the rack. The cylindrical workpiece processing fixture adopting the technical scheme has the characteristics of being simple in structure, convenient to operate, strong in adaptability and good in clamping effect.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures for mechanical parts, and in particular relates to a columnar workpiece processing fixture. Background technique [0002] During the processing of casting molds, it is usually necessary to process the cylindrical workpiece. When the workpiece is processed, it is usually necessary to clamp and position it first, and then make the tool with the adjusted position to process it. At present, when processing a columnar workpiece, two splints are usually used to clamp it from both sides of the columnar workpiece respectively. The center hole is machined in the center of the two ends of the columnar workpiece. While clamping the columnar workpiece from both sides with a splint, two tops are used to tighten the columnar workpiece from both ends of the columnar workpiece respectively. However, this clamping method It will make the operation complicated and the structure complicated. Contents of ...
