Automatic pressing mechanism of engine cylinder head oil passage hole sealing steel ball

Abstract

The invention discloses an automatic pressing mechanism of an engine cylinder head oil passage hole sealing steel ball. The automatic pressing mechanism comprises a worktable, a pressing unit, a positioning unit and a feeding unit, wherein the pressing unit, the positioning unit and the feeding unit are located in a PLC control system and under the control of a main program, the pressing unit is arranged in a positioning mode and used for horizontally pressing the steel ball, the positioning unit is arranged in a positioning mode and used for positioning a workpiece, namely an engine cylinder head, and the feeding unit is used for loading and unloading the workpiece for the positioning unit. The pressing unit is provided with a ball outlet according to which when the steel ball pressing work is performed, the steel ball disengages from the pressing unit and instantly faces an engine cylinder head oil passage hole positioned by the positioning unit, and the opening of the engine cylinder head oil channel hole is located above a working item face. According to the automatic pressing mechanism of the engine cylinder head oil passage hole sealing steel ball, automatic pressing of the engine cylinder head steel ball can be achieved, production efficiency is improved, labor intensity is relieved, the assembling quality of a product is improved, and the automatic pressing mechanism has the advantages of being compact in structure, low in manufacturing cost and reliable in operation. The automatic pressing mechanism is suitable for automatic pressing of the engine cylinder head oil passage hole sealing steel ball.

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...

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
