Semiautomatic pressing machine

Abstract

The invention provides a semiautomatic pressing machine which comprises a pressing machine shell and an electrical cabinet, wherein a spiral coder, a motor, a motor bracket, a coupling and a screw rod are sequentially arranged in the pressing machine shell from top to bottom; a guide rail assembly is composed of a guide rail bracket, a guide rail base for fixing the guide rail bracket and a guide rail connection plate for fixing the guide rail bracket, and a square guide rail arranged on the guide rail bracket; the back surface of a sliding connection plate is in contact with the square guide rail; the front surface of the sliding connection plate is fixed with a screw rod connection frame and a pressing device; the screw rod connection frame is in threaded connection with the screw rod; and the pressing device comprises a pressing plate, a cylinder and a press head. The semiautomatic pressing machine performs dual monitoring on the pressure and the stroke of the spiral coder through a pressure sensor and effectively controls the clamping force among parts, thereby ensuring that the clamping force can be kept in a relative position and workpieces contained in the pressing machine can not be damaged; and a method of pressing multiple workpieces in one step and cross-using two positioning tools is used, thereby improving the work efficiency.

Description

technical field [0001] The invention belongs to a press-fitting machine, in particular to a semi-automatic press-fitting machine for assembling small parts. Background technique [0002] In the assembly of the workpiece, it is often encountered in the assembly process that needs to be press-fitted, such as the contained part and the containing part are in a clearance fit, and the holding force on the contained part is generated by deforming the containing part. As an important equipment in the factory, the press-fitting machine is widely used in the press-fitting process of bearings, couplings, gears, impellers, pulleys, etc. Commonly used press-fitting machines generally adopt a hydraulic method, which can provide a large tonnage of press-fitting force. Its control accuracy directly affects the final assembly accuracy of the press-fitting parts, and plays a key role in the performance of the assembled mechanism components. [0003] Most of the press-fitting machines in the...

Problems solved by technology

[0003] Most of the press-fitting machines in the prior art are general-purpose press-fitting machines, which use position sensors to limit the position. The pressure and press-fit depth cannot be effectively monitored. When the contained parts to be pressed are fragile materials (glass or gemstones, etc.), the press-fit force The control of the pressure becomes the key parameter of the press-fitting process, therefore, the press-fitting machine of the prior art is not suitable for the press-fitting of small parts with higher requirements on the pressure and the depth of the press-fitting
