Description

Technical Field

[0001] The present invention relates to the field of press-fitting, and more particularly to an automatic press-fitting machine for steel ball pins. Background Art

[0002] In modern manufacturing, the press-fitting operation of steel ball pins is a key link in the production processes of many products, and is widely used in many fields such as automobile manufacturing, machining, and electronic equipment. The traditional press-fitting method of steel ball pins mainly relies on manual operation, which has a series of problems that cannot be ignored. Firstly, manual press-fitting faces the dilemma of low efficiency. In the manual operation mode, workers need to position and press each steel ball pin one by one, and each press-fitting operation takes a long time. From picking and placing workpieces to applying pressure to complete press-fitting, the entire process is cumbersome and slow. With the continuous increase in the market demand for products, the efficiency of manual press-fitting far cannot meet the needs of large-scale production, which not only limits the production capacity of enterprises, but also may lead to an extended delivery cycle, affecting the competitiveness of enterprises in the market. Manual operation is affected by various factors such as the technical level, working state, and fatigue degree of workers. There are differences in the operation methods and forces of different workers, and even for the same worker operating at different times, it is difficult to ensure that the force, depth, and perpendicularity of each press-fitting are exactly the same. And the press-fitting quality of steel ball pins has a crucial impact on the performance and service life of products. In addition, manual press-fitting also has the problem of high labor intensity. Workers repeatedly perform high-intensity press-fitting operations for a long time, which easily causes physical fatigue and occupational diseases, damaging the physical health of workers. This not only increases the labor cost of enterprises, but also may further reduce work efficiency due to the health problems of employees, and even lead to safety accidents, affecting the normal production order of enterprises. With the intelligent development trend of the manufacturing industry, higher requirements are put forward for steel ball pin press-fitting equipment. However, some existing automatic press-fitting equipment also has many deficiencies in practical applications. Some equipment has a single function and cannot meet the press-fitting requirements of products of different specifications; the accuracy and stability of some equipment need to be improved, and errors are likely to occur during the press-fitting process; some equipment has complex operations and high maintenance costs, increasing the use cost of enterprises. Therefore, it is of great practical significance to develop an automatic press-fitting machine for steel ball pins that is efficient, accurate, easy to operate, and reasonable in cost.
