Detailed Description
The technical scheme of the present invention is further described in non-limiting detail below with reference to the preferred embodiments and the accompanying drawings.
As shown in fig. 1, an oil seal pressing mechanism according to a preferred embodiment of the present invention is used for pressing an oil seal 1 into a mounting hole 2a of a workpiece 2, the mounting hole 2a is provided on an end face 2b of the workpiece 2, and the workpiece 2 further includes a positioning shoulder 2c annularly surrounding the mounting hole 2 a.
The oil seal pressing mechanism comprises a guide block 11 and a pressing block 12, wherein a guide hole 3 and a positioning opening 10 matched and positioned with a positioning shoulder 2c are formed in the center of the guide block 11, and after the positioning opening 10 and the positioning shoulder 2c are matched and installed, the guide hole 3 and a mounting hole 2a are mutually aligned. The pressing block 12 includes a guide portion 4, a pressing portion 5, and a supporting portion 6 coaxially provided in this order.
The guide part 4 is matched with the guide hole 3, and the pressing block 12 can move linearly relative to the guide block 11 through the matching of the guide part 4 and the guide hole 3.
The diameter of the pressing portion 5 is slightly smaller than the outer diameter of the oil seal 1 so as not to interfere with the mounting hole 2a when the oil seal 1 is pressed in. The oil seal 1 can be sleeved on the supporting portion 6, and the diameter of the supporting portion 6 is slightly smaller than the inner diameter of the oil seal 1, so that the oil seal 1 is sleeved on the supporting portion 6 with higher positioning accuracy. The terminal surface of oil blanket 1 can laminate with extrusion 5, extrusion 5 and supporting part 6 cooperation location oil blanket 1 prevent that oil blanket 1 from taking place the slope in the extrusion process.
The extrusion part 5 is provided with a limiting part 7, the diameter of the limiting part 7 is larger than the outer diameter of the oil seal 1, and after the oil seal 1 is installed in place, the limiting part 7 just contacts with the end face 2b of the workpiece 2, so that the pressing-in block 12 is limited to be pressed down continuously. The guide block 11 is provided with a receiving hole 8 at the center for receiving the pressing portion 5.
In order to further increase the positioning accuracy of the limiting portion 7, it is preferable that the diameter of the limiting portion 7 is slightly smaller than the diameter of the accommodating hole 8, and the press-in block 12 and the guide block 11 have higher coaxial accuracy by the cooperation of the limiting portion 7 and the accommodating hole 8 and the cooperation of the guide portion 4 and the guide hole 3.
