Description

Technical Field

[0001] This invention relates to the field of drive shaft assembly technology, specifically to an automotive drive shaft assembly device. Background Technology

[0002] A driveshaft is the shaft in a universal joint drive system that transmits power. It is a high-speed, low-support rotating body, composed of a shaft tube, a telescopic sleeve, and universal joints. The driveshaft connects or assembles various components and is a movable or rotating circular component, generally made of lightweight alloy steel tubing with good torsional strength. In front-engine, rear-wheel-drive vehicles, it transmits the rotation of the transmission to the final drive. It can consist of several sections connected by universal joints. The driveshaft is a crucial component in the automotive transmission system, its function being to work with the gearbox and drive axle to transmit the engine's power to the wheels, thus generating driving force for the vehicle.

[0003] The assembly process for drive shafts involves four steps: first, pressing in the universal joint; second, pressing in the shaft tube; third, welding; and fourth, balancing the drive shaft. During the pressing in of the shaft tube, workers need to move the drive shaft end with the universal joint installed above the press machine and fix it using the clamping mechanism. Then, the worker places the shaft tube between the ends of the two drive shafts and presses both ends of the tube to the ends. However, the increased flexibility of the drive shaft end after the universal joint is installed necessitates that workers straighten the drive shaft end before clamping it to prevent tilting, and ensure coaxiality. This results in slow installation speed and low production efficiency. After assembly, the different weights of the two ends of the shaft tube require workers to support the drive shaft as it is pushed out by the press machine to prevent it from tilting and falling on the heavier side. Therefore, we propose an automotive drive shaft assembly device. Summary of the Invention

[0008] Preferably, the rotating component includes a first transmission gear fixedly connected to the outer side of one end of the support rod, a transmission chain meshing with the outer side of the first transmission gear, a second transmission gear meshing with one end of the transmission chain, one end of the second transmission gear being rotatably connected to the inner wall of the movable seat, and an adjusting gear fixedly connected to the other end of the second transmission gear. One end of the adjusting gear is rotatably connected to the inner wall of the movable seat, a driving gear meshing below the adjusting gear, both ends of the driving gear being rotatably connected to the inner wall of the movable seat, a transmission rack meshing below the driving gear, and the transmission rack being fixedly connected to the inner wall of the press machine body.

[0009] Preferably, the clamping component includes two L-shaped plates located above one end of the placement plate. A fixing rod is fixedly connected to the inner side of the L-shaped plates, and a telescopic rod is slidably connected to the inner wall of the fixing rod. A compression spring is fixedly connected to one end of the telescopic rod, and one end of the compression spring is fixedly connected to the inner wall of the fixing rod. A compression pad is fixedly connected to the end of the telescopic rod away from the compression spring. A limit block is fixedly connected to the lower part of the L-shaped plates. A limit groove is provided on the inner wall of the movable seat, which can slide and connect with the limit block. A return spring is fixedly connected to one end of the limit block, and one end of the return spring is fixedly connected to the inner wall of the limit groove. A connecting groove is provided on the inner wall of the L-shaped plates, and a limit component is provided on the inner wall of the connecting groove, which can clamp the side of the end of the transmission shaft and drive the L-shaped plates to move.

[0010] Preferably, the limiting component includes a sliding block that is slidably connected to the inner wall of the connecting groove. One end of the sliding block is fixedly connected to a compression pad II. The upper and lower sides of the end of the sliding block away from the compression pad II are respectively fixedly connected to sliders. The inner wall of the connecting groove is provided with a sliding groove that can be slidably connected to the sliders.

[0016] In use, this application features a clamping mechanism that can clamp both ends of the drive shaft, and a supporting mechanism that supports the drive shaft tube. Compared to existing technologies, where workers need to straighten the drive shaft ends before fixing them to prevent tilting, and ensure coaxiality, resulting in slow installation and low production efficiency, and where the different weights of the two ends of the shaft tube cause the press machine to push the drive shaft out, requiring workers to support it to prevent it from tilting and falling to the heavier side, this application's clamping mechanism allows workers to simply place the drive shaft ends into the clamping mechanism. As the clamping mechanism moves towards both ends of the press machine, it automatically adjusts and clamps the drive shaft ends, reducing the workload of workers and increasing the pressing speed. Furthermore, after the drive shaft ends are pressed into the tube, the supporting mechanism automatically adjusts the support position of the tube, preventing the drive shaft from tilting to one side when it is pushed out.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figure 1-7This invention provides a technical solution: an automotive driveshaft assembly device, comprising a press-fit machine body 1; two limiting rods 2 located on the inner wall of the press-fit machine body 1, with both ends of the limiting rods 2 fixedly connected to the inner wall of the press-fit machine body 1; two clamping mechanisms 3 located at both ends of the limiting rods 2, capable of clamping and fixing the driveshaft end 7 to be assembled; and a supporting mechanism 4 located between the two clamping mechanisms 3, capable of supporting the driveshaft tube 8. In use, the operator first places the end of the driveshaft into the clamping mechanism 3, which then moves along the surface of the limiting rods 2 towards the end of the press-fit machine body 1. During movement, the clamping mechanism 3 automatically adjusts the shape of the driveshaft end 7 and clamps it, ensuring that one end of the driveshaft end 7 abuts against the abutment post 6 of the press-fit machine body 1, reducing the workload of the operator and eliminating the need for... The worker carries the drive shaft end 7 towards the end of the press machine body 1 to increase the pressing speed. After the two drive shaft ends 7 are placed, the worker places the drive shaft tube 8 above the support mechanism 4. Through the clamping mechanism 3 and the support mechanism 4, the end of the drive shaft and the tube are aligned on the same axis. The worker starts the press machine body 1, which pushes the clamping mechanism 3 at one end to move. The clamping mechanism 3 moves the drive shaft end 7 and squeezes the tube, so that both ends of the tube are connected to the end of the drive shaft. After the drive shaft is pressed, the press machine body 1 moves backward, and the clamping mechanism 3 moves the end of the drive shaft away from the abutment post 6 of the press machine body 1. At the same time, the support mechanism 4 automatically adjusts the support position of the drive shaft according to the model of the drive shaft. Thus, the press-pressed drive shaft is pushed upward by the support mechanism 4, preventing the drive shaft from tilting to one side when it is pushed out.

[0029] The clamping mechanism 3 includes a movable seat 30 slidably connected to the limiting rod 2. One end of the movable seat 30 is fixedly connected to a pneumatic telescopic rod 31, and one end of the pneumatic telescopic rod 31 is fixedly connected to the main body 1 of the press machine. A groove 32 is provided on the inner wall of the movable seat 30. A placement member 33 is provided on the inner wall of the groove 32 to place the end of the drive shaft 7. A clamping member 34 is provided above the placement member 33 to clamp the surface of the end of the drive shaft 7. When the clamping mechanism 3 is working, the operator places the end of the drive shaft 7 into the placement member 33, which supports the end of the drive shaft 7. The operator then activates the pneumatic telescopic rod 31, which drives the movable seat 30 along the limiting rod. 2. The surface slides, so that the movable seat 30 approaches the abutment post 6 at one end of the press body 1. During the movement, the movable seat 30 adjusts and clamps the posture of the drive shaft end 7 through the clamping member 34, so that one end of the drive shaft end 7 abuts against the abutment post 6 of the press body 1. The universal joints at both ends of the drive shaft end 7 are clamped to prevent bending at the universal joints during the press. Since the two ends of the drive shaft are connected to different parts of the car, the two ends of the drive shaft are of different sizes and models. The movable seats 30 at both ends of the press body 1 are of different sizes to clamp the two ends of the drive shaft respectively and to facilitate the loading of the drive shaft end 7 by the staff.

[0030] The placement component 33 includes a placement plate 35 located on the inner wall of the groove 32. The placement plate 35 is slidably connected to the inner wall of the groove 32. A concave groove 331 is provided on the upper part of the placement plate 35 to support the drive shaft. A support rod 36 is fixedly connected to the inner wall of the placement plate 35. The two ends of the support rod 36 are rotatably connected to the inner wall of the groove 32. One end of the support rod 36 protrudes through the inner wall of the movable seat 30 and is provided with a rotating component 37 that can drive the support rod 36 to rotate according to the movement of the movable seat 30. When the placement component 33 is working, initially, the two movable seats 30 are in the middle position of the press body 1, which makes it convenient for the operator to place the end 7 of the drive shaft on the placement plate 35 without the operator having to carry the end 7 of the drive shaft to both ends of the press body 1. The movable seats 30 are located in the middle position of the press body 1. In the middle position, the placement plate 35 is tilted to one side. The operator places the end 7 of the drive shaft into the surface of the tilted placement plate 35. Under the action of gravity, the end 7 of the drive shaft slides down along the surface of the placement plate 35, so that the end 7 of the drive shaft abuts against the inner wall of one end of the groove 32. As the moving seat 30 moves toward the end of the press machine body 1, the rotating component 37 drives the support rod 36 to rotate. The support rod 36 drives the placement plate 35 to rotate in the inner wall of the groove 32, thereby rotating the end of the drive shaft to a horizontal state. During the rotation, the end of the drive shaft is squeezed by the clamping component 34 at one end of the universal joint of the end of the drive shaft 7, thereby preventing the universal joint of the end of the drive shaft 7 from bending and not unfolding. In addition, the horizontal state of the end of the drive shaft 7 makes it easy to fit with the abutment post 6 at the end of the press machine body 1.

[0031] Rotating component 37 includes a transmission gear 38 fixedly connected to the outer side of one end of the support rod 36. A transmission chain 39 meshes with the outer side of the transmission gear 38. A transmission gear 310 meshes with one end of the transmission chain 39. One end of the transmission gear 310 is rotatably connected to the inner wall of the movable seat 30. An adjusting gear 311 is fixedly connected to the other end of the transmission gear 310. One end of the adjusting gear 311 is rotatably connected to the inner wall of the movable seat 30. A drive gear 312 meshes below the adjusting gear 311. Both ends of the drive gear 312 are rotatably connected to the inner wall of the movable seat 30. A transmission rack 313 meshes below the drive gear 312. The transmission rack 313 is fixedly connected to the inner wall of the press body 1. When rotating component 37 is working, the transmission gear 38 moves... The moving seat 30 drives the driving gear 312 to move along the surface of the transmission rack 313. The driving gear 312 meshes with the transmission rack 313, causing the driving gear 312 to rotate. The driving gear 312 drives the adjusting gear 311 to rotate. The adjusting gear 311 drives the transmission gear 310 to rotate. The transmission gear 310 drives the transmission chain 39 to rotate. The transmission chain 39 drives the transmission gear 38 to rotate. The transmission gear 38 drives the support rod 36 to rotate. Thus, the support rod 36 drives the placement plate 35 to rotate to a horizontal state. After the moving seat 30 moves to the end of the pressing machine body 1 through the driving gear 312 and the adjusting gear 311, the placement plate 35 rotates to a horizontal state.

[0032] The clamping member 34 includes two L-shaped plates 314 located above one end of the placement plate 35. A fixing rod 315 is fixedly connected to the inner side of the L-shaped plate 314. A telescopic rod 316 is slidably connected to the inner wall of the fixing rod 315. A compression spring 317 is fixedly connected to one end of the telescopic rod 316. One end of the compression spring 317 is fixedly connected to the inner wall of the fixing rod 315. A compression pad 318 is fixedly connected to the end of the telescopic rod 316 away from the compression spring 317. A limit block 319 is fixedly connected below the L-shaped plate 314. A limit block 319 is provided on the inner wall of the movable seat 30, which can slide with the limit block 319. The positioning groove 320 has a limit block 319 with a fixed end connected to a return spring 321. One end of the return spring 321 is fixedly connected to the inner wall of the positioning groove 320. The inner wall of the L-shaped plate 314 has a connecting groove 322. The inner wall of the connecting groove 322 has a limit member 323 that can clamp the side of the end 7 of the drive shaft and drive the L-shaped plate 314 to move. When the clamping member 34 is working, the placement plate 35 rotates, causing one end of the drive shaft 7 to tilt upward. The tilted end of the drive shaft 7 presses against the compression pad 318. The compression pad 318 drives the telescopic rod 316 along the fixed rod 315. The inner wall slides and compresses the compression spring 317, causing the compressed spring 317 to push the compression pad 318 to press against the end of the drive shaft 7, preventing the universal joint at the end of the drive shaft 7 from bending. The compression pad 318 is made of rubber, thus avoiding damage to the surface of the end of the drive shaft 7. When the placement plate 35 rotates to a horizontal position, the limiting member 323 clamps the horizontal sides of the end of the drive shaft 7, preventing the end of the drive shaft 7 from bending in the horizontal direction and facilitating the press-fitting of the drive shaft. After the drive shaft is press-fitted, the limiting member 323 releases the clamp. In addition to the compression of the outer periphery of the drive shaft end 7, while the limiting member 323 moves away from the drive shaft end 7, the limiting member 323 drives the two L-shaped plates 314 to move away from each other. The L-shaped plates 314 drive the limiting block 319 to slide along the inner wall of the limiting groove 320 and compress the return spring 321, so as to release the upper limit of the drive shaft, making it easier to lift the press-fitted drive shaft. When the drive shaft is pushed out, the limiting member 323 resets, and the return spring 321 in the compressed state pushes the limiting block 319 to slide along the inner wall of the limiting groove 320 and drives the two L-shaped plates 314 to move closer to each other.

[0033] The limiting member 323 includes a sliding block 324 that is slidably connected to the inner wall of the communicating groove 322. One end of the sliding block 324 is fixedly connected to a compression pad 325. Sliding blocks 326 are fixedly connected to the upper and lower sides of the end of the sliding block 324 away from the compression pad 325, respectively. The inner wall of the communicating groove 322 has a sliding groove 327 that can slidably connect with the sliding blocks 326. A concave plate 328 is fixedly connected to the end of the sliding block 324 near the sliding blocks 326. A clamping arm 329 is fixedly connected to one end of the concave plate 328. The inner side of the holding arm 329 is provided with an arc-shaped end 332. A pneumatic telescopic rod 330 is fixedly connected to the end of the concave plate 328 away from the sliding block 324. One end of the pneumatic telescopic rod 330 is fixedly connected to the inner wall of the movable seat 30. When the limiting member 323 clamps the end 7 of the transmission shaft, the pneumatic telescopic rod 330 extends and drives the concave plate 328 to move. The concave plate 328 drives the clamping arm 329 to approach the end 7 of the transmission shaft. The arc-shaped end 332 of the clamping arm 329 is used to clamp the arc-shaped part of the surface of the end 7 of the transmission shaft. The compression limit is applied, and simultaneously, the concave plate 328 drives the sliding block 324 to slide along the inner wall of the connecting groove 322. The sliding block 324 drives the slider 326 to slide along the inner wall of the sliding groove 327. The sliding block 324 pushes the compression pad 325 to compress the end of the transmission shaft 7 to limit the end of the transmission shaft 7. When the press-fitted transmission shaft is ejected, the pneumatic telescopic rod 330 retracts, and the pneumatic telescopic rod 330 drives the concave plate 328 to move. The concave plate 328 simultaneously drives the clamping arm. 329 and sliding block 324 move away from the end 7 of the drive shaft. Sliding block 324 drives slider 326 to slide along the inner wall of groove 327. When slider 326 slides to the end of groove 327, sliding block 324 drives slider 326 to continue moving away from the end 7 of drive shaft, thereby causing slider 326 to drive L-shaped plate 314 to move away from the end 7 of drive shaft, so that L-shaped plate 314 no longer limits the upper end of drive shaft, and thus cooperates to push drive shaft out.

[0034] The supporting mechanism 4 includes a support base 40 fixedly connected to the main body 1 of the press machine. A pneumatic telescopic rod 41 is fixedly connected above the support base 40. A connecting plate 42 is fixedly connected to the end of the pneumatic telescopic rod 41 away from the support base 40. A support plate 43 is slidably connected to the inner wall of the connecting plate 42. A concave arc 45 is formed on the surface of the support plate 43. An electric telescopic rod 44 is fixedly connected to one end of the support plate 43. One end of the electric telescopic rod 44 is fixedly connected to the inner wall of the connecting plate 42. When the drive shaft is pushed out, the electric telescopic rod 44 is extended according to the model of the drive shaft. The electric telescopic rod 44 drives the support plate 43 to slide along the surface of the connecting plate 42, thereby allowing the support plate 43 to move along the surface of the drive shaft to cooperate with the support plate 43 to move to the center of gravity position of the assembled drive shaft. The pneumatic telescopic rod 41 pushes the connecting plate 42 to move upward, and the connecting plate 42 drives the support plate 43 to move upward to cooperate in smoothly pushing out the drive shaft.

[0035] Example 2

[0036] like Figure 8 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that pressure sensors 5 are fixedly connected to both ends of the support plate 43. When the pneumatic telescopic rod 41 extends, it drives the connecting plate 42 upward. The connecting plate 42 then drives the support plate 43 upward to lift the transmission shaft above the support plate 43. Since the ends 7 of the transmission shaft pressed into the two ends of the shaft tube have different weights, the pressure on both ends of the support plate 43 is measured by a pressure transmitter. After measurement, the pneumatic telescopic rod 41 retracts, allowing the transmission shaft to be supported again by the placement plate 35 and the support plate 43. Based on the pressure measured by the pressure sensors 5 at both ends, the electric telescopic rod 44 extends, driving the support plate 43... The movement is coordinated to support different positions of the drive shaft, so that when the pneumatic telescopic rod 41 drives the connecting plate 42 to move upward again, the support plate 43 can stably lift the drive shaft upward. Furthermore, the pressure sensor 5 can automatically adjust the extension of the electric telescopic rod 44 according to the different models of the ends pressed into the shaft tube. It is not necessary to calculate the center of gravity of the drive shaft after pressing in advance and then control the extension of the electric telescopic rod 44. It is only necessary to adjust the extension of the electric telescopic rod 44 by sensing the pressure on both ends of the support plate 43 by the pressure sensors 5 at both ends. It is not necessary to measure the center of gravity of the drive shaft after pressing and then adjust the extension of the electric telescopic rod 44 for each batch of new drive shafts.
