Description

Technical Field

[0001] This utility model relates to the field of spindle testing technology, and in particular to a spindle testing fixture for clutch driven disc assembly. Background Technology

[0002] The spindle is connected to the driven plate via splines or keyways, effectively transmitting the power from the engine to the driven plate to ensure normal vehicle operation. The spindle provides necessary support to ensure the driven plate remains stable during operation, reducing vibration and wear.

[0003] Currently, the spindles of the products on the automated production line are rectangular spline spindles. If new product series are added to the existing automated production line, the rectangular spline of the inner hub will be changed to an involute spline. This makes it impossible to test directly on the testing machine. The product needs to be transferred to another production line for testing, which affects production efficiency. Changing the testing fixtures is too troublesome. Repeatedly changing the testing fixtures will consume a lot of time and also affect efficiency. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 7 This utility model provides an embodiment of a spindle inspection fixture for a clutch driven disc assembly, comprising a base plate 1 and a base plate 2, a mounting base 3, and a limiting block 4. The base plate 2 is positioned above the base plate 1, and the mounting base 3 is rotatably connected to the upper end of the base plate 2. Limiting blocks 4 are evenly distributed on the surface of the mounting base 3. A base 5 is fixedly mounted on the upper end of the mounting base 3, and limiting grooves are evenly distributed on the lower end of the base 5. The limiting grooves of the base 5 are adapted to the limiting blocks 4. A spline column 6 is provided on the upper end of the base 5, and a [missing information - likely a component or part] is provided on one side of the base plate 2. The rotating handle 12 drives the base plate 2 to rotate. The lower end of the base plate 1 is provided with a roller 20 for movement. When the spindle testing fixture of the clutch driven plate assembly is in use, during testing, the rotating handle 12 is rotated according to the type of spline column 6 to be tested. The base plate 2 rotates at the same time, thus realizing the replacement of the spline column 6 type. When another type of spline column 6 needs to be tested, the rotating handle 12 is rotated again to change the position of the spline column 6. There is no need to disassemble and replace the spline column 6, which greatly improves the testing efficiency.

[0025] Please see Figure 1 and Figure 3In this embodiment, a bearing seat 7 is fixedly installed on the upper end of the base plate 1. A connecting shaft 8 is rotatably connected to the end of the bearing seat 7. A worm gear 9 is fixedly connected to the surface of the connecting shaft 8. A bearing seat 10 is fixedly installed on the upper end of the base plate 1. A worm 11 is rotatably connected to the end of the bearing seat 10. The worm 11 meshes with the worm gear 9. A rotating handle 12 is fixedly connected to one end of the worm 11. The base plate 2 is fixedly connected to the upper end of the connecting shaft 8. A support frame 13 is fixedly connected to the upper end of the base plate 1. A sliding rod 14 is slidably connected to the surface of the support frame 13. A positioning head 15 is fixedly connected to the upper end of the sliding rod 14. Positioning holes are evenly distributed at the lower end of the base plate 2. The positioning holes at the lower end of the base plate 2 are adapted to the positioning head 15. A spring 16 is sleeved on the surface of the sliding rod 14. A guide shaft 17 is fixedly installed on the upper end of the base plate 1. A guide shaft 17 is fixedly connected to the lower end of the sliding rod 14. A slider 18 is connected to a guide shaft 17. The end of the positioning head 15 is also connected to the guide shaft 17. In use, the base 5 is first placed on the upper end of the mounting base 3 and the base 5 is fitted with the limiting block 4. Then, the base 5 is fixed with bolts, thus completing the installation of the spline column 6. The base plate 1 is fixedly installed on the testing machine next to the production line. During testing, the rotating handle 12 is rotated according to the type of spline column 6 to be tested. The base plate 2 rotates at the same time, thus realizing the replacement of the spline column 6 type. Before rotating the base plate 2, the sliding rod 14 is pulled down. The positioning head 15, which is fixedly connected to the upper end of the sliding rod 14, moves down and disengages from the positioning hole at the lower end of the base plate 2. At this time, the base plate 2 can be rotated. The positioning head 15 is used to determine the position of the base plate 2 and prevent the position of the spline column 6 from changing due to accidental contact with the rotating handle 12.

[0026] Please see Figure 4 - Figure 6In this embodiment, the lower end of the base plate 1 is provided with a groove, and a frame 19 is slidably connected in the groove at the lower end of the base plate 1. The roller 20 is rotatably connected to the surface of the frame 19. Connecting rods 21 are fixedly connected to the four corners of the upper end of the frame 19. The upper ends of the connecting rods 21 pass through the base plate 1 and are slidably connected to the base plate 1. A support frame 22 is fixedly connected to the upper end of the base plate 1, and the connecting rods 21 are slidably connected to the support frame 22. A spring 23 is sleeved on the surface of the connecting rods 21. The lower ends of the frame 19 are provided with grooves on both sides, and magnets 24 are slidably arranged in the grooves at the lower end of the frame 19. A sliding rod 25 is fixedly connected to the upper end of the magnet 24. The end passes through the frame 19, and the surface of the slide bar 25 is fitted with a spring 3 26. When the tooling needs to be moved during the installation of the base plate 1, the roller shaft 20 connected to the surface of the frame 19 facilitates the movement of the tooling. The spring 23 is used to pop the roller shaft 20 out of the groove at the lower end of the base plate 1. The connecting rod 21 is used to drive the frame 19 to move. The magnet 24 is used to attract the installation location. In this way, when the installation is not horizontal, the attraction force provided by the magnet 24 plays a certain positioning role. This makes it easier for the workers to align the mounting holes of the base plate 1 with the screw holes at the installation location, greatly improving the installation speed. After the base plate 1 is installed, the roller shaft 20 retracts into the groove at the lower end of the base plate 1.

[0027] When using it, first place the base 5 on the upper end of the mounting base 3 and make the base 5 fit with the evenly distributed limit blocks 4 on the surface of the mounting base 3. Then use bolts to fix the base 5, thus completing the installation of the spline column 6.

[0028] The base plate 1 is fixedly installed on the testing machine next to the production line. During testing, various types of spline columns 6 are installed on the upper end of the base plate 2. Rotate the handle 12 according to the type of spline column 6 to be tested. Rotating the handle 12 drives the worm gear 11 to rotate at the bearing seat 10. The worm wheel 9, which is meshed with the worm gear 11, rotates at the bearing seat 7 through the connecting shaft 8. The base plate 2 is fixedly connected to the connecting shaft 8. The base plate 2 rotates at the same time, thus realizing the replacement of the spline column 6 type. When another type of spline column 6 needs to be tested, continue to rotate the handle 12 to change the position of the spline column 6.

[0029] Before rotating the base plate 2, pull down the slide bar 14. The positioning head 15, which is fixedly connected to the upper end of the slide bar 14, moves down and disengages from the positioning hole at the lower end of the base plate 2. At this time, the base plate 2 can rotate. When rotating to the next type of spline column 6, the positioning head 15 is re-fitted with the positioning hole at the lower end of the base plate 2 under the push of the spring 16. The positioning head 15 is used to determine the position of the base plate 2 and prevent the position of the spline column 6 from changing due to accidental contact with the rotating handle 12. The guide shaft 17 is used to ensure the stability of the movement of the positioning head 15 and to ensure the support strength of the slide bar 14. The slider 18 is slidably connected to the guide shaft 17 and fixedly connected to the slide bar 14 to further ensure the stability of the movement of the positioning head 15.

[0030] When installing the base plate 1, if the fixture needs to be moved, the roller 20 rotatably connected to the surface of the frame 19 facilitates the movement of the fixture. The spring 23 is used to pop the roller 20 out of the groove at the lower end of the base plate 1. The connecting rod 21 is used to drive the frame 19 to move. The magnet 24 is used to attract the fixture to the installation location. In this way, when installing on a non-horizontal surface, the attraction force provided by the magnet 24 plays a certain positioning role, which makes it easier for the workers to align the mounting holes of the base plate 1 with the screw holes of the installation location, greatly improving the installation speed. The slide bar 25 is used to ensure the stability of the movement of the magnet 24 and to ensure that the magnet 24 can be tightly attracted to the installation location. After the base plate 1 is installed, the roller 20 retracts into the groove at the lower end of the base plate 1.

[0031] Through the above steps, when using the spindle testing fixture of the clutch driven plate assembly, during testing, the handle 12 is rotated according to the type of spline 6 to be tested, and the base plate 2 rotates simultaneously. This achieves the replacement of the spline 6 type. When testing another type of spline 6, the position of the spline 6 can be changed by continuing to rotate the handle 12, without the need to disassemble and replace the spline 6, which greatly improves the testing efficiency. The positioning head 15 is used to determine the position of the base plate 2 to prevent the position of the spline 6 from changing due to accidental activation of the handle 12.
