AI Technical Summary

Technical Problem

In the existing technology, the clamping structure of hollow hardware is complex and costly, and clamping from the outside will damage the appearance of the parts and cause quality problems.

Method used

Design a fixture for clamping and releasing hollow cylindrical parts. By setting a transfer rod between a fixed plate and a movable plate, the transfer rod is inserted into the inner hole of the part for internal clamping. Combined with an elastic clamping structure, such as an elastic clamping part or a spring ball, the internal clamping and release of the part can be realized.

Benefits of technology

It achieves internal clamping protection of parts, avoids external damage, has a simple structure, reduces costs, and is suitable for parts with different internal hole structures.

Abstract

The utility model discloses a hollow cylindrical part clamping jig, including fixed plate and movable plate, movable plate sets up in the upside of fixed plate, and movable plate is equipped with the material shifting rod that projects downward, and material shifting rod is used for the hole of the extension of the part of waiting for processing, and the clamping force is applied from the inside of the part of waiting for processing, and the inside clamping of the part of waiting for processing is realized, and the lower extreme of fixed plate is equipped with the hole of the material shifting rod passing through, when pulling movable plate, fixed plate restricts the part with material shifting rod upward movement, makes material shifting rod and the hole of the part of waiting for processing separate and realizes the material of discharging. Through the hole of material shifting rod in the part of waiting for processing and the inside of the part of waiting for processing, the inside clamping of the part of waiting for processing is carried out, and the blanking is completed with fixed plate cooperation, and the workpiece integrity is protected through internal support, and the simple structure.
