Friction welding spindle head based on support rod type transverse movement

Abstract

The invention relates to the technical field of friction welding, in particular to a friction welding spindle head based on support rod type transverse movement. The friction welding spindle head comprises a spindle head, a transverse moving mechanism and a transmission mechanism arranged on the top of the transverse moving mechanism, wherein the transverse moving mechanism comprises a support rod; the two ends of the support rod are equipped with supporting bases; each supporting base comprises a supporting block, a splicing hole is formed in the middle position of the top of the supporting block, and the support rod is in splicing fit to the splicing hole; a supporting rod is arranged on the top of each supporting block; the transmission mechanism comprises a power device which comprisesa motor; and the left side of the motor is equipped with a lead screw. The motor drives the lead screw to rotate, and drives a transmission block and a transverse moving block to move, and the transverse moving block drives a spindle head on the bottom to move, so that separation of the spindle head and the motor is realized, and influences, on the spindle head, of motor vibration are reduced.

Description

technical field [0001] The invention relates to the technical field of friction welding, in particular to a friction welding spindle head based on a support bar type lateral movement. Background technique [0002] Friction welding is under the action of pressure, under the action of constant or increasing pressure and torque, using the relative motion between the welding contact end faces to generate friction heat and plastic deformation heat on the friction surface and its surrounding areas, so that the surrounding areas The temperature rises to a temperature range close to but generally lower than the melting point. Generally, the rotation of the spindle head provides torque for the welding contact end surface, and then the motor drives the spindle head to move laterally. Usually, the motor and the spindle head in the factory are fixed on a support frame. superior. [0003] But when the motor and the spindle head are installed in one piece, the motor will vibrate when it ...

AI Technical Summary

Problems solved by technology

[0003] But when the motor and the spindle head are installed in one piece, the motor will vibrate when it works, and then bring it to the spindle head to vibrate together, so the spindle head will shake, so that the torque generated by the rotation will change, and the applied pressure will not be constant. state, thereby reducing the quality of friction welding, resulting in a decline in the quality of products produced by the factory
