Semi-automatic press for mechanical assembly

Abstract

The invention belongs to machinery production technological devices and particularly relates to a semi-automatic press for mechanical assembly. A pneumatic control system (26) and an electrical control system (27) are fixedly mounted on a lower framework (25), a work panel (11) is fixedly mounted at the upper end of the lower framework (25), an optoelectronic switch (8) a safety limited post (30), an upper framework (12) and four guide optical axes (4) are respectively and fixedly mounted on the work panel (11), a gas-liquid pressurized cylinder (13) is fixed on an upper fixed plate (2), a pressure head (7) used for mounting a workpiece in a pressing mode is fixed below a movable guide plate (6), a press block (20) used for triggering a sensor is fixed on one side face of the movable guide plate (6), and a fixture (9) is fixedly mounted at a place, corresponding to the pressure head (7), in the middle of the upper face of a lower fixed plate (10). The semi-automatic press for the mechanical assembly is reasonable in structure and safe, convenient and fast to operate, can accurately judge the press-in position of a part and whether pressure is right and appropriate or not, and can realize accurate measurement of displacement and the pressure and achieve an automatic alarming function when an out-of-tolerance situation happens.

Description

technical field [0001] The invention belongs to mechanical manufacturing process equipment, in particular to a semi-automatic press for mechanical assembly. Background technique [0002] In the automotive steering pump manufacturing industry, sliding bearings, steel balls, pulleys, flanges and other parts are often press-fitted during assembly. In order to completely ensure the quality of the press-in, it is necessary to accurately judge whether the press-in position and the press-in force of the press-in parts are correct. Whether it is correct or not is used to judge the degree of cooperation between parts and prevent loosening of parts during work. The above two points are the key to ensure the normal operation of the steering pump. Once it fails, it will cause steering failure and personal injury to the driver. However, the existing air-fuel pressurized press can only achieve a simple pressing action, and cannot For accurate measurement of displacement and pressure, th...

Problems solved by technology

The above two points are the key to ensure the normal operation of the steering pump. Once it fails, it will cause steering failure and personal injury to the driver. However, the existing air-fuel pressurized press can only achieve a simple pressing action, and cannot For accurate measurement of displacement and pressure, the position of parts after press-fitting of this equipment can only be accurately judged by visual inspection or by measuring with the help of inspection tools. The judgment of pressing force can only be judged by visual inspection of the instantaneous pressure value of the pressure gauge on the gas-liquid booster cylinder. Roughly calculated, it is not very accurate. This obviously cannot meet the demand for the strict press-fitting process, and will also invisibly bury the hidden danger of sudden quality accidents, which poses a great threat to the safety of automobile use.
