[0002] The automotive drive shaft is a core component connecting the transmission and drive wheels. Made of high-strength alloy steel, it possesses torsional and fatigue-resistant properties, enabling it to withstand dynamic loads under complex road conditions. Its universal joint structure achieves angle compensation through a ball-cage design, adapting to wheel movement. Some models utilize constant velocity universal joints to further enhance steering power continuity, making it a crucial component for ensuring vehicle handling and driving stability.

[0003] In current factory operations involving the disassembly of reworked drive shafts, the workbenches generally suffer from limited functionality. When dealing with drive shafts of different rework fault types, workers need to repeatedly disassemble the drive shaft components. During this disassembly, matching fixtures are required. However, due to the limited functionality of existing fixtures, it is necessary to frequently change the appropriate fixtures. This frequent fixture change not only significantly extends the disassembly time of a single machine but also wastes the rework efficiency of the drive shaft.

[0004] Therefore, a rework disassembly workbench for automotive drive shafts is proposed. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Please refer to Figure 1-6 This utility model provides a technical solution: a rework disassembly workbench for automotive drive shafts, including a workbench body 1 and a drive shaft body 2. A first clamp, a second clamp, a third clamp, a fourth clamp, and a fifth clamp are installed on the upper end of the workbench body 1. A receiving mechanism is fixedly installed on the lower end of the workbench body 1. The receiving mechanism is adapted to the fourth clamp. The first clamp includes a tripod clamp 3, which is fixedly installed on the workbench body 1. The closed ring design of the tripod clamp 3 forms a naturally stable structure. The weight of the drive shaft body 2 is evenly distributed through three support points, avoiding the risk of shaft tilting or slipping caused by single-point force in traditional clamps.

[0016] Furthermore, the second fixture includes a support rod 4, which is fixedly mounted on the worktable body 1. A fixing plate 46 is threadedly fixed to the top of the support rod 4. A transmission rod 42 is slidably mounted on the fixing plate 46. A clamping plate 43 is fixedly mounted to the bottom of the transmission rod 42 and engages with the upper end of the drive shaft body 2. A movable table 41 is fixedly mounted on the top of the transmission rod 42. A first drive screw 44 is threaded onto the movable table 41. The bottom end of the first drive screw 44 is rotatably mounted on the fixing plate 46. The worktable body 1 is fixedly mounted with a fixed plate 46. A fixing block 45 is fixedly installed and is engaged with the lower side of the upper end of the drive shaft body 2. When it is necessary to disassemble the parts on the drive shaft body 2, the upper end of the drive shaft body 2 is fixed on the fixing block 45 and the clamping plate 43 respectively. Then, the first drive screw 44 is manually rotated. The rotation of the first drive screw 44 drives the movable table 41 to move upward. The movable table 41 drives the transmission rod 42 to move. The transmission rod 42 drives the clamping plate 43 to move upward, so that the parts at one end of the drive shaft body 2 can be easily disassembled.

[0017] Furthermore, the third clamp includes a fixing rod 5, the lower end of which is fixedly mounted on the workbench body 1, and the upper end of which is threadedly fixed with a positioning plate 51. A mounting platform 52 is fixedly mounted on the positioning plate 51, and a second drive screw 53 is threadedly engaged on the mounting platform 52. The bottom end of the second drive screw 53 contacts the top end of the drive shaft body 2. When it is necessary to remove the shaft on the drive shaft body 2, the entire part of one end of the drive shaft body 2 is placed in the slot on the workbench body 1. Then, the second drive screw 53 on the mounting platform 52 is manually rotated. By rotating the second drive screw 53 downward, the drive shaft body 2 can be easily removed from the part at one end.

[0018] Furthermore, the fourth clamp includes two slide rails 6, each with two sets of pneumatic sliders 61 slidably mounted on it. Each set of pneumatic sliders 61 has a vertical plate 62 fixedly mounted on it by bolts. Each vertical plate 62 has a placement groove, and the two drive shaft bodies 2 are respectively placed inside the two placement grooves. A cylinder 63 is fixedly mounted on each pneumatic slider 61 by bolts. An adapter rod 64 is fixedly mounted on the upper end of the cylinder 63. A connecting plate 65 is fixedly mounted on the top of the adapter rod 64. Two locking blocks 66 are fixedly mounted on the lower side of the connecting plate 65. Each locking block 66 has a locking groove. The two drive shaft bodies 2 are respectively snapped onto the upper surfaces. When both ends of the drive shaft body 2 need to be removed at the same time, simply place the drive shaft body 2 on the upright plate 62, then drive the cylinder 63 to move the adapter rod 64 downward, the adapter rod 64 moves the connecting plate 65, and the connecting plate 65 moves the snap-fit ​​block 66 to snap onto the upper surface of the drive shaft body 2, thereby fixing the drive shaft body 2. Then, start the pneumatic slider 61 and use the pneumatic slider 61 to slide on the slide rail 6 to both sides, so that the parts on both ends of the drive shaft body 2 can be easily removed using the upright plates 62 on both sides.

[0019] Furthermore, the fifth clamp includes a tiger-mouth clamp 8, which is fixedly installed on the worktable body 1. The tiger-mouth clamp 8 forms a ring-shaped wrapping clamp on the drive shaft body 2, and evenly distributes the axial tensile force and radial impact force to the clamp surface.

[0020] Furthermore, the receiving mechanism includes a receiving box 7, which is fixedly installed on the workbench body 1. Multiple buffer springs 71 are fixedly installed on the inner wall of the receiving box 7. The other end of each buffer spring 71 is fixedly installed with an inner box 72. A silicone buffer pad 73 is fixedly installed on the inner wall of the inner box 72. The silicone buffer pad 73 is in contact with the drive shaft body 2. A damper 74 is fixedly installed on the inner wall of the receiving box 7. The other end of the damper 74 is fixedly installed on the outer surface of the inner box 72. The disassembled shaft will fall downward into the silicone buffer pad 73 on the inner box 72. When the shaft falls into the silicone buffer pad 73, the impact force of the falling shaft will be offset by the silicone buffer pad 73 and the buffer springs 71, thereby effectively protecting and receiving the shaft. At the same time, the damper 74 can effectively prevent the buffer springs 71 from constantly rebounding and causing abnormal use of the buffer springs 71.

[0021] The working principle is as follows: When it is necessary to disassemble the drive shaft body 2, different fixtures installed on the worktable body 1 are used to handle different problems on the drive shaft body 2, and different sizes of drive shaft bodies 2 can also be disassembled. When it is necessary to disassemble the parts on the drive shaft body 2, the upper end of the drive shaft body 2 is fixed on the fixing block 45 and the clamping plate 43 respectively. Then, the first drive screw 44 is manually rotated. The rotation of the first drive screw 44 drives the movable table 41 to move upward. The movable table 41 drives the transmission rod 42 to move. The transmission rod 42 drives the clamping plate 43 to move upward, so that the parts at one end of the drive shaft body 2 can be easily disassembled. When it is necessary to remove the shaft on the drive shaft body 2, the entire part at one end of the drive shaft body 2 is placed in the slot on the worktable body 1. Then, the second drive screw 53 on the mounting table 52 is manually rotated. The second drive screw 53 rotates to the... The downward movement allows for easy removal of the drive shaft body 2 from one end of the component. The removed shaft will fall into the silicone buffer pad 73 on the inner housing 72. When the shaft falls into the silicone buffer pad 73, the silicone buffer pad 73 and the buffer spring 71 will counteract the impact of the falling shaft, effectively protecting it. When both ends of the drive shaft body 2 need to be removed simultaneously, simply place the drive shaft body 2 on the upright plate 62, then drive the cylinder 63 to move the adapter rod 64 downwards. The adapter rod 64 moves the connecting plate 65, and the connecting plate 65 engages the locking block 66 on the upper surface of the drive shaft body 2, thus securing the drive shaft body 2. Next, activate the pneumatic slider 61, which slides on the slide rail 6 to both sides, allowing for easy removal of the components from both ends of the drive shaft body 2 using the upright plates 62 on both sides.
