The clamping mechanism of the reaming and flanging machine of the pneumatic actuator spring

Abstract

The invention provides a mold closing mechanism of a reaming and flanging machine for a pneumatic actuator spring. By using the mold closing mechanism, synchronous reaming and flanging operations for two ends of a copper tube of the pneumatic actuator spring can be realized, and further the processing efficiency is improved. The mold closing mechanism comprises push units and a driving device and is characterized in that the driving device comprises a mold closing air cylinder; a push rod is connected to the output end of the mold closing air cylinder, and a striking block is arranged on the push rod; each push unit comprises a limiting seat, a driving rod, a rotating shaft, a push block, a first bevel gear, a second bevel gear, a lead screw, a lead screw nut and a support; each rotating shaft is supported on the corresponding support; each first bevel gear is fixedly arranged on the corresponding rotating shaft; one end of each driving rod is fixedly connected with the corresponding rotating shaft, and the other end of each driving rod is positioned between the corresponding limiting seat and the corresponding striking block; each push block is provided with a perforating hole, and each lead screw nut is fixed in the corresponding perforating hole; the threaded part of each lead screw is in threaded connection with the corresponding lead screw nut; each second bevel gear meshed with the corresponding first bevel gear is fixedly arranged at the polished part of the corresponding lead screw; the number of the push units is two, and thread directions of the lead screws of the two push units are oppositely arranged.

Description

technical field [0001] The invention relates to processing equipment for pneumatic actuator springs, in particular to a mold clamping mechanism of a hole reaming and flanging machine for pneumatic actuator springs. Background technique [0002] The pneumatic actuator spring includes a spring body, a spring sleeve and a hollow connecting rod. The connecting rod runs through the spring sleeve fixed at both ends of the spring body, and the connecting rod guides the expansion and contraction of the spring; the end of the connecting rod is provided with a reaming and flanging structure to prevent the spring sleeve from moving outward in the axial direction of the connecting rod. The existing pneumatic actuator spring reaming and flanging machine needs to reverse the direction of the pneumatic actuator spring and reinstall it in the mold after reaming and flanging one end of the copper pipe, and then perform reaming and flanging on the other end of the copper pipe. Side operation...

Problems solved by technology

The existing pneumatic actuator spring reaming and flanging machine needs to reverse the direction of the pneumatic actuator spring and reinstall it in the mold after reaming and flanging one end of the copper pipe, and then perform reaming and flanging on the other end of the copper pipe. Side operation, that is, the reaming and flanging at both ends of the copper tube of the pneumatic actuator spring needs to be processed in two processes, and the processing efficiency is low
