Automatic Press-fitting Mechanism for Sealing Steel Ball in Oil Channel Hole of Engine Cylinder Head

Abstract

The invention discloses an automatic press-fitting mechanism for sealing steel balls in an engine cylinder head oil channel hole, which includes a workbench and a press-fitting unit for horizontally pressing the steel balls under the control of the main program of the PLC control system and positioned respectively. The positioning unit, the positioning unit used to position the workpiece, that is, the engine cylinder head, the feeding unit used to load and unload the workpiece for the positioning unit, the press-fitting unit has the ability to be positioned when the steel ball is detached from the press-fitting unit when the steel ball is pressed. The ball outlet of the oil passage hole of the engine cylinder head after the unit is positioned, and the orifice of the oil passage hole of the engine cylinder head is located above the working surface. The automatic press-fit mechanism of the engine cylinder head oil passage hole sealing steel ball of the present invention can realize the automatic press-fit of the engine cylinder head steel ball, improve production efficiency, reduce labor intensity, improve the assembly quality of the product, and has the advantages of compact structure, easy production Low cost and reliable operation. The invention is suitable for the automatic press-fitting of the steel balls in the oil passage hole of the engine cylinder head.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to the processing technology of a vehicle engine, in particular to an automatic press-fitting mechanism for sealing steel balls in an oil passage hole of an engine cylinder head. Background technique [0002] At present, steel balls are used to block the oil passage hole of the engine cylinder head after the machining is completed. In the process of pressing steel balls, manual pressing or semi-automatic hydraulic pressing is mostly used, among which: [0003] (1) Manual press-fitting method, the press-fitting steel ball needs to be manually loaded during the press-fitting process, the operation is cumbersome, the labor intensity of the press-fitting personnel is high, the production efficiency is low, and there is a safety hazard of the punch pressing the hand , The assembly quality cannot be effectively guaranteed, and there are often missing or improper assembly, which affects...

AI Technical Summary

Problems solved by technology

[0003] (1) Manual press-fitting method, the press-fitting steel ball needs to be manually loaded during the press-fitting process, the operation is cumbersome, the labor intensity of the press-fitting personnel is high, the production efficiency is low, and there is a safety hazard of the punch pressing the hand , the assembly quality cannot be effectively guaranteed, and there are often missing or improper assembly, which affects the performance of the engine

In addition, with the increase of engine output, the manual press-fitting method can no longer meet the customer's demand for engine output and quality;

[0004] (2) The semi-automatic hydraulic press-fitting method, in addition to the indispensable steel ball press-fitting mechanism, in order to meet the smooth press-fitting of the steel balls and ensure that the workpiece remains in the same position during the steel ball press-fitting process, additional equipment must be added. The workpiece locking device is used to balance the press-fitting force, which increases the production cost of the equipment, resulting in complex structure of the equipment, high production cost, and cumbersome press-fitting action

The patented solution belongs to semi-automatic operation. This mechanism requires manual loading and unloading, and manual precise positioning of the workpiece. Due to the limitation of the structure of the stamping rod, the force on the connection between the head of the stamping rod and the guide part is relatively concentrated during the press-fitting process, and frequent movements are likely to cause The head of the stamping rod is broken, resulting in pressure leakage of the steel ball
