Description

Technical Field

[0001] This utility model relates to the field of automotive parts disassembly devices, specifically to a star-shaped sleeve disassembly device. Background Technology

[0002] The automotive half-shaft assembly consists of three main components: the fixed-end universal joint, the intermediate shaft, and the sliding-end universal joint. The connection and power transmission between the intermediate shaft and the fixed-end universal joint are achieved by the engagement of the external spline of the intermediate shaft and the internal spline of the star-shaped sleeve in the fixed-end universal joint, with axial movement prevented by a wire retaining ring through a hole.

[0003] To prevent circumferential clearance (which can cause vibration and noise during product use), the external spline of the intermediate shaft and the internal spline of the star sleeve are usually tightly fitted, making disassembly difficult. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a star-shaped sleeve disassembly device, which mainly solves the problem that the current intermediate shaft external spline and the star-shaped sleeve internal spline are tightly fitted, making disassembly difficult.

[0005] The technical solution of this utility model is as follows: A star-shaped sleeve disassembly device includes a frame, on which a power source is mounted, and further includes... The push rod is driven by a power source to move up and down. The platform is provided with at least two slides, the distance between the two slides is adjustable, and the upper surface of the slides is used for star-shaped sleeve placement; A rod groove is provided between the two slide plates, corresponding to the lower part of the push rod, and is used for the passage of the intermediate shaft.

[0006] The push rod is the drive rod of the power source or is connected to the drive rod of the power source via a coupling.

[0007] The power source is a hydraulic cylinder.

[0008] The skateboard is connected to the platform by fasteners.

[0009] The slide plate is provided with a long groove, and the platform is provided with mounting holes that are opposite to the long groove.

[0010] It also includes a protective cover, which is located on the upper surface of the slide plate and has a cavity inside for placing the star-shaped sleeve. The top of the protective cover has a through hole for the push rod to pass through.

[0011] The power source is installed on the top of the bracket.

[0012] The beneficial effects of this utility model are: This utility model provides a star-shaped sleeve disassembly device that does not require forceful hammering for disassembly, but adopts mechanical disassembly, which greatly reduces the labor intensity of workers and is more efficient.

[0014] Figure 2 This is a partial side view of one embodiment of the present invention.

[0015] Figure 3 This is a perspective view of one embodiment of the present invention. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings. A star-shaped sleeve disassembly device includes a frame 1, on which a power source 2 is provided, and a push rod 21 driven by the power source to move up and down; a platform 3, on which at least two sliding plates 31 are provided, the distance between the two sliding plates is adjustable, and the upper end surface of the sliding plates is used to place the star-shaped sleeve 91; a rod groove 32 is provided between the two sliding plates, corresponding to the push rod below, and is used for the passage of the intermediate shaft 92. In use, the two sliding plates are opened, the workpiece is placed in, and then the sliding plates are closed to provide support for the star-shaped sleeve, with the intermediate shaft passing through the rod groove, ensuring that the intermediate shaft is located below the push rod. Then the sliding plates are fixed, the power source is turned on, and the push rod pushes the intermediate shaft to achieve disassembly.

[0017] In this embodiment, as shown in the figure, the push rod is the drive rod of the power source or is connected to the drive rod of the power source via a coupling.

[0018] In this embodiment, as shown in the figure, the power source is a hydraulic cylinder. Hydraulics offer advantages such as lower cost and greater controllability.

[0019] In this embodiment, as shown in the figure, the skateboard and the platform are connected by fasteners 33. The fasteners can be screws or bolts, etc.

[0020] In this embodiment, as shown in the figure, the slide plate is provided with a long groove 34, and the platform is provided with mounting holes opposite to the long groove. This facilitates position adjustment.

[0021] In this embodiment, as shown in the figure, a protective cover 5 is also included. The protective cover is disposed on the upper end surface of the slide plate, and its interior has a cavity for placing the star-shaped sleeve. The top of the protective cover has a through hole 51 for the push rod to pass through. This enhances safety.

[0022] In this embodiment, as shown in the figure, the power source is installed on the top of the bracket.
