Precision machining tooling for mechanical press parts

Abstract

A precision machining tool for mechanical press parts, comprising: a card body, the card body includes a bottom plate, two support plates and a side plate arranged vertically at intervals are arranged on the bottom plate, and support shafts are arranged on the top of the two support plates, so that There is a 90° angle between the end surface and the front end surface of the support plate and the transition is through a rounded corner. The bottom plates outside the two support plates are respectively provided with arc-shaped guide rail grooves; the 90° rotating worktable, the 90° rotating workbench includes Worktable, support rods and arc-shaped guide rails. The worktable is hinged to the support shaft through a self-lubricating bushing at the bottom. There are trapezoidal grooves and V-shaped positioning blocks on the top and bottom of the worktable. The arc-shaped guide rails are movably installed on the arc In the surface guide rail groove; the internal gear pair, the internal gear pair includes a sector-shaped internal gear installed on the lower surface of the worktable. It has the advantages of stable structure, high rigidity, improved processing efficiency, high clamping and positioning accuracy, high rotary repeat positioning accuracy, firm and reliable braking, etc., which improves the processing quality and efficiency of parts.

Description

Technical field: [0001] The invention relates to a precision machining tool for parts of a mechanical press. Background technique: [0002] At present, the main parts such as flywheels and support sleeves widely used in mechanical presses usually need to process long and deep oblique holes inside to lubricate the main drive rotating parts of mechanical presses, and some disc parts also need to be processed on the side. Straight, inclined hole drilling, reaming or milling of inclined surfaces. How to firmly clamp and fix parts such as flywheels, support sleeves or discs on the workbench of gantry drills, milling machines and other equipment or ground platforms, and realize the precision of long and deep inclined hole drilling, reaming or milling on oblique vertical planes , high-efficiency processing, and the existing process tooling can satisfy ordinary parts of this type with low requirements. There are many problems in the existing technical structure: on the one hand, d...

AI Technical Summary

Problems solved by technology

[0003] In order to make up for the deficiencies in the prior art, the present invention provides a precision machining tool for mechanical press parts, which solves the problem of movement in the axial and radial gaps of the workpiece and the bending plate of the fixture during the rotation process after the parts are clamped, and the rotation guide , The problem of poor positioning accuracy solves the problem of repeated positioning accuracy of the rotation tilt angle or low display resolution; solves the problem that the rigidity of the process tooling is insufficient, and it is easy to cause deformation or loosening during processing, which greatly affects the accuracy of the processed parts.
