Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing and relates to a pressing tool for an oil seal cover and a grease cover for a drive shaft sleeve. Background Technology

[0002] The universal joint drive shafts are connected by drive shaft sleeves 3. Sleeves 3 require press-fitting of an inner grease cap 2 and an outer oil seal cap 1. Figure 1 As shown, the existing press-fitting method involves first pressing the inner grease cap with a press-fitting tool, and then pressing the outer oil seal cap with another press-fitting tool. This method is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems existing in the prior art and provide a press-fit tool for the oil seal cover and grease cover of the drive shaft slide sleeve. This press-fit tool can press-fit the inner grease cover and the outer oil seal cover of the slide sleeve in one go, saving time and effort and increasing efficiency. It can also ensure that the inner grease cover and the outer oil seal cover are on the same central axis, without affecting the installation accuracy of the drive shaft and avoiding the occurrence of oil leakage problems.

[0004] To achieve the above objectives, the solution of this utility model is: a pressing tool for an oil seal cover and a grease cover of a drive shaft sleeve, comprising a support frame, a servo motor linear push rod, an upper pressing head, and a lower tooling; the support frame includes a pressing platform at the lower end, a vertical support fixed to one end of the pressing platform, and a horizontal support plate fixed to the upper end of the vertical support; the servo motor linear push rod is fixed to the lower end face of the horizontal support plate; the upper pressing head is T-shaped and fixed to the lower end of the servo motor linear push rod, with a circular groove on its bottom surface that matches the outer diameter of the flange of the oil seal cover and three or more identical magnet mounting slots on the same circumference around the circular groove, wherein identical magnets are embedded in the magnet mounting slots; the lower tooling is a cylinder or hollow cylinder with a diameter matching the bottom diameter of the inner end of the grease cover, its lower end is fixed to the upper end face of the pressing platform, and its central axis coincides with the central axis of the servo motor linear push rod, the upper pressing head and the circular groove of the upper pressing head, the drive shaft sleeve, the oil seal cover, and the grease cover.

[0005] In use, insert the outer oil seal cover into the circular groove of the upper pressure head. The upper end face of the bottom wall of the outer oil seal cover is attracted to the bottom surface of the upper pressure head by a magnet. Place the inner grease cover on the upper end face of the lower fixture, place the drive shaft sleeve on the lower fixture, start the servo motor linear push rod, and the upper pressure head presses against the upper end face of the drive shaft sleeve. After the inner grease cover and the outer oil seal cover are pressed into shape, the servo motor linear push rod retracts.

[0006] The advantages of this invention compared to existing technologies are as follows: This press-fit tool can press-fit the inner grease cap and outer oil seal cap of the sliding sleeve in one step, saving time and effort and increasing efficiency. It also ensures the coaxiality of the inner grease cap and outer oil seal cap, preventing any impact on the installation accuracy of the drive shaft and avoiding oil leakage. Furthermore, it can adapt to different models of drive shaft sliding sleeves simply by changing the upper press head and lower tooling, making it widely applicable. Attached Figure Description

[0009] The present invention will be further described below with reference to specific embodiments.

[0010] like Figure 2 As shown, this embodiment includes a support frame 4, a servo motor linear actuator 5, an upper pressure head 6, and a lower tooling 7. The support frame 4 includes a lower pressing platform 41, a vertical support 42 fixed to one end of the pressing platform 41, and a horizontal support plate 43 fixed to the upper end of the vertical support 43. The servo motor linear actuator 5 is fixed to the lower end face of the horizontal support plate 43. The upper pressure head 6 is T-shaped and fixed to the lower end of the servo motor linear actuator 5. Its bottom surface has a circular groove 61 that matches the outer diameter of the flange of the oil seal cover 1, and three (or four, five, etc.) identical magnet mounting slots on the same circumference around the circular groove 61. Identical magnets 8 are embedded in the magnet mounting slots. The lower fixture 7 is a cylinder or hollow cylinder whose diameter matches the bottom diameter of the inner end grease cap 3. Its lower end is fixed to the upper end face of the pressing platform 41. Its central axis coincides with the central axis of the servo motor linear push rod 5, the upper pressure head 6 and the circular groove 61 of the upper pressure head, the drive shaft sleeve 2, the oil seal cover 1 and the grease cap 3.

[0011] In use, insert the outer oil seal cover 1 into the circular groove 61 of the upper pressure head. The upper end face of the bottom wall of the outer oil seal cover 1 is attracted to the bottom surface of the upper pressure head 6 by the magnet 8. Place the inner grease cover 3 on the upper end face of the lower fixture 7, place the drive shaft sleeve 2 on the lower fixture 7, start the servo motor linear push rod, and the upper pressure head 6 presses against the upper end face of the drive shaft sleeve 2. After the inner grease cover 3 and the outer oil seal cover 1 are pressed into shape, the servo motor linear push rod retracts.

[0012] The above-described embodiments are merely preferred and exemplary, and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
