Description

Technical Field

[0001] This utility model relates to the field of drive shaft assemblies, and specifically to a disassembly tool with a cross-shaped flange fork. Background Technology

[0002] After the cross shaft is installed on the flange fork, rework and disassembly are extremely difficult due to the lack of a good stress point. The bushing must be completely removed before the cross shaft can be easily removed. The current method involves fixing the flange fork, removing the retaining circlip, and then forcibly hammering the bushing out with a hammer before removing the cross shaft. However, hammering the flange fork cross shaft is extremely inefficient, physically demanding for operators, and repeated impacts can damage the bushing, rendering it unusable. This method needs improvement. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a disassembly tool with a cross-shaft flange fork, which reduces the labor intensity of disassembling the cross-shaft flange fork, improves work efficiency, and ensures that the parts are not damaged during disassembly.

[0004] The purpose of this utility model is achieved through the following technical solution: This disassembly fixture with a cross shaft flange fork includes an upper base plate and a lower base plate arranged symmetrically, with both sides of the two plates connected and fixed by a side plate; the journals at the upper and lower ends of the cross shaft are mounted on the flange fork through bushings; a disassembly slot is symmetrically opened at the front and rear ends of the upper base plate, and a disassembly slot is also opened at the corresponding position on the lower base plate, for a total of four disassembly slots; the disassembly slot includes an inner U-shaped groove that matches the outer diameter of the bushing and an outer U-shaped groove that matches the ear of the flange fork, and the inner U-shaped groove and the outer U-shaped groove are connected by a step.

[0005] As a further technical solution, the outer U-shaped grooves of the four disassembly slots are provided with different sizes to meet the disassembly and assembly of universal joints of different specifications.

[0006] As a further technical solution, the side plate is connected to the upper base plate and the lower base plate by fixing bolts.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. Improved disassembly efficiency of the cross shaft on the flange fork, applicable to batch rework, and disassembly will not damage the cross shaft or bushing, allowing for reuse;

[0009] 2. The multiple U-shaped groove (disassembly slot) structure can meet the disassembly and assembly of universal joints of different specifications, with strong versatility and multiple uses. Attached Figure Description

[0014] Mark explanation: side plate 1, upper bottom plate 2, lower bottom plate 3, inner U-shaped groove 4, outer U-shaped groove 5, step 6, flange fork 7, ear 8, cross shaft 9, shaft sleeve 10, fixed bolt 11. Specific implementation

[0015] The utility model will be introduced in detail in combination with the drawings below:

[0016] Embodiment: as shown in the accompanying Figures 1-4 , this cross shaft flange fork disassembly tool includes side plate 1, upper bottom plate 2, lower bottom plate 3, inner U-shaped groove 4, outer U-shaped groove 5, step 6, flange fork 7, ear 8, cross shaft 9, shaft sleeve 10 and fixed bolt 11.

[0017] Reference accompanying Figure 1 , 3 , upper bottom plate 2 and lower bottom plate 3 are symmetrically arranged up and down, and one side plate 1 is arranged on the left and right sides of upper bottom plate 2 and lower bottom plate 3 simultaneously, and the side plate 1 is connected between upper bottom plate 2 and lower bottom plate 3 by fixed bolt 11.

[0018] As shown in Figure 4 , the shaft necks of the upper and lower ends of cross shaft 9 are installed in the corresponding ear holes of flange fork 7 ear 8 through shaft sleeve 10 and snap spring. Figure 2 、 3 As shown, one disassembly clamping groove is symmetrically provided at the front and rear ends of upper bottom plate 2, and disassembly clamping grooves are also provided at the corresponding positions on lower bottom plate 3, a total of four disassembly clamping grooves, preferably, the disassembly clamping grooves are located at the middle positions of the front and rear ends. Further, each disassembly clamping groove includes an inner U-shaped groove 4 and an outer U-shaped groove 5, and the inner U-shaped groove 4 and the outer U-shaped groove 5 are connected by a step 6, wherein the inner U-shaped groove 4 is matched with the outer diameter of the shaft sleeve 10 (the inner U-shaped groove 4 is slightly larger than the shaft sleeve 10), and the outer U-shaped groove 5 is matched with the ear 8 of the flange fork 7, so that the ear 8 front end can be clamped into the outer U-shaped groove 5, and the shaft sleeve 10 extends downward from the inner U-shaped groove 4.

[0019] Preferably, the four dismounting clamping grooves are provided with different size specifications, which are determined according to the size of the ear 8 of the flange fork 7, so as to ensure that the ear 8 can be perfectly stressed when embedded, and the size of the ear 8 of the flange fork 7 is generally related to the size of the universal joint, and the size of the ear of the flange fork is basically the same when the size of the universal joint is the same, so the four dismounting clamping grooves can be designed to be different in size to realize universality and meet the dismounting of universal joints of different sizes.

[0020] The working process of the utility model is as follows:

[0021] When dismounting, the device is placed on the workbench of a hydraulic machine, then the ear 8 of the flange fork 7 of the cross shaft 9 to be dismounted is embedded into the outer U-shaped groove 5 of the upper bottom plate 2, and the shaft sleeve 10 is passed out downward from the inner U-shaped groove 4. Then, the bottom of the flange fork 7 is held by one hand, the clamping spring at both ends is removed by using a clamping spring pliers, then the hydraulic machine is started, the pressure head is directed to the center of the shaft sleeve 10 and gradually pressed downward, and the shaft sleeve 10 at the top will be completely pressed out of the ear hole of the flange fork 7. After being turned over by 180°, the other shaft sleeve 10 is also completely pressed out of the ear hole of the flange fork 7, and the cross shaft 9 is removed, at this time, the flange fork 7 and the cross shaft 9 are completely separated and not damaged.

[0022] It can be understood that, for those skilled in the art, equivalent replacement or change of the technical scheme and the utility model concept of the utility model should belong to the protection range of the claims of the utility model.
