Description

Technical Field

[0001] The utility model relates to the technical field of oil seal assembly tooling, in particular to an oil seal pressing tool. Background Art

[0002] In the machinery manufacturing industry, oil seals are key components to prevent leakage of lubricating oil, hydraulic oil and other media, and are widely used in key parts such as bearings, gearboxes, and transmission shafts of various mechanical equipment. The installation quality of oil seals directly affects the performance, service life and operational safety of mechanical equipment. However, during the press-fitting process of oil seals, due to improper operation, insufficient equipment precision or the material of the oil seal itself, the oil seal is often easily damaged, resulting in seal failure.

[0003] Traditional oil seal press-fitting methods often use simple mechanical pressure for press-fitting. For example, in an automated production line, the oil seal is mainly installed by a robot that grabs and places it on the workpiece oil seal installation position. After the oil seal is in place, the hydraulic press drives the press to press the oil seal into place. Although this method is simple to operate, it has many shortcomings. First, due to the inaccurate control of the press force, it is easy to cause the oil seal lip to deform, tear or crack, affecting the sealing performance. Secondly, the lack of buffering and guiding mechanisms during the press-fitting process makes it easy for the oil seal to deviate or skew during the press-fitting process and cause damage, further increasing the risk of damage.

[0004] In order to solve the above problems, a variety of oil seal press-fitting auxiliary tools have appeared on the market, but these tools still have certain limitations in function and structure. For example, although some tools can reduce the press-fitting force, they lack precise guiding and positioning functions and cannot guarantee the stability and accuracy of the oil seal during the press-fitting process. Summary of the invention

[0005] The utility model provides a telescopic oil seal pressing tool, which is not only simple in structure but also has guiding and positioning functions, can effectively prevent the oil seal from being damaged during the pressing process, improves product quality, and thus solves the problems existing in the above-mentioned existing oil seal pressing tools.

The positioning guide device 2 is installed inside the press body 1, in front of the press-fitting position of the oil seal 7. The positioning guide device 2 has a positioning groove 2-2 that matches the oil seal 7, which is used to accurately locate the position of the oil seal 7 to ensure that the oil seal 7 will not shift or skew during the press-fitting process. The design of the positioning guide device 2 takes into account the size and shape of the oil seal 7 to ensure that the oil seal 7 can be accurately placed in the workpiece.

[0032] The positioning guide device 2 is connected to the press body 1 through the positioning guide rod 3. The positioning guide rod 3 is located in the cavity 1-1 and the cavity 2-1, and the positioning guide rod 3 passes through the positioning guide device 2 through the perforation on the positioning guide device 2 and extends out. A baffle can be provided at the end. The positioning guide rod 3 is usually designed to be long and has a certain rigidity and wear resistance to ensure the stability and accuracy of the oil seal 7 during the press-fitting process.

[0041] (2) The robot sets the oil seal 7 on the upper end of the positioning guide device 2;

[0042] (3) The hydraulic press drives the utility model to descend, and the positioning groove 2-2 of the positioning guide device 2 enters the inner cavity of the workpiece 6 to play a guiding role until the end face contacts the end face of the workpiece 6. After the contact, the spring 4 is compressed, and then the positioning guide positioning device 2 shrinks upward until the oil seal 7 is pressed into place;

[0043] (4) After the press-fitting is completed, the hydraulic press drives the utility model to rise, completing the entire press-fitting process.
