Friction welding machine limiting rod clearance-eliminating device

Abstract

The invention provides a friction welding machine limiting rod clearance-eliminating device, which comprises a shell, an ejector rod, a wedge block and a power device. The ejector rod is horizontally arranged in the shell; the wedge block is vertically arranged in the shell; a first inclined surface of the ejector rod and a second inclined surface of the wedge block overlap together; the power device is connected with the wedge block; upward movement of the wedge block is transformed into horizontal movement of the ejector rod; and through arranging a sliding chute or a spring, automatic reset can be realized after use. According to the friction welding machine limiting rod clearance-eliminating device provided by the invention, the ejector rod is pushed through the wedge block so as to move axially, so that an axial clearance generated during welding piece clamping is eliminated; and the inclined surfaces are self-locked, so that the friction welding machine limiting rod clearance-eliminating device is reliable in eliminating the clearance, simple and effective in structure, and more accurate in abrasion value measurement.

Description

technical field [0001] The invention relates to the field of friction welding, in particular to a backlash elimination device for a limit rod of a friction welding machine Background technique [0002] During friction welding, it is necessary to accurately control the amount of wear. There is a gap between the weldment and the ejector rod. If there is a gap, errors will occur when measuring the amount of wear. However, since the position of the weldment clamping is different each time, the gap are different, the measured errors are also different, and the amount of wear cannot be accurately controlled. Contents of the invention [0003] The purpose of the present invention is to provide a friction welding machine limit rod anti-backlash device for the deficiencies of the prior art [0004] In order to realize the purpose of the present invention, the present invention adopts following technical scheme: [0005] A backlash elimination device for a limit rod of a friction ...
