Spline Hub Boring Center Hole Pneumatic Fixture

Abstract

The invention discloses a pneumatic clamp for a boring central hole of a splined hub. The pneumatic clamp for the boring central hole of the splined hub comprises a base which comprises a horizontal plate and a vertical plate; the horizontal plate is fixedly connected with an air cylinder; two sliding linings are arranged at the top of the vertical plate; guide rods are arranged inside the two sliding linings in a sliding mode; the two guide rods which are in the same structure comprise main body portions which are arranged in the middle and screw portions which are arranged at the left ends and the right ends; a rotation pressure plate is connected between right side screw portions of the two guide rods; a clamp screw is in screw joint with the middle of the rotation pressure plate; a cylinder connecting plate is connected between left side screw portions of the two guide rods; a pull rod is in screw joint with the middle of the cylinder connecting plate; the pull rod penetrates into a sliding base in a sliding mode; the right end of the sliding base is fixedly connected to the vertical plate; a vertical through hole is formed in the middle of the sliding base; a wedge-shaped sliding block is arranged at the top of a piston rod; the wedge-shaped sliding block penetrates the vertical through hole; the vertical plate is fixedly connected with a V-shaped block. The pneumatic clamp for the boring central hole of the splined hub has the advantages of overcoming the time and labor wasting disadvantage of previous clamps, reducing the labor intensity, improving the production efficiency, reducing the production costs and improving yield of processed products.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a spline hub boring center hole jig. Background technique [0002] With the rapid development of my country's industry and the continuous advancement of science and technology, the competition in the field of mechanical processing has become increasingly fierce, and has now entered the era of meager profits. This situation forces the machining industry to continuously innovate and improve, abandon the previous production methods with high energy consumption, high consumables, high labor intensity and low efficiency, and actively look for new ways to save energy and reduce consumption, manpower and material resources. [0003] The spline hub is an important part of the non-constant velocity transmission shaft assembly. According to its design requirements, the center hole needs to be bored. The traditional spline hub boring method is to position and clamp the spline...

AI Technical Summary

Problems solved by technology

The traditional spline hub boring method is to position and clamp the spline hub on the three-jaw chuck on the fixed workbench for processing. When clamping the workpiece, it is necessary to manually tighten and loosen the screw many times, which is labor-intensive and expensive. Low efficiency, becoming a bottleneck process restricting production capacity

In short, the existing spline hub boring center hole fixture needs to be clamped by manually tightening the screw rod, which has low processing efficiency and relatively high labor intensity for workers.
