[0032] See attached document Figure 1-4 A torsion damper shape inspection fixture includes a workbench 1, a support inspection platform 2 on one side of the top of the workbench 1, the top of the support inspection platform 2 can hold the torsion damper to be inspected, a concave receiving groove 3 on the side of the support inspection platform 2, a rotating platform 4 inside the concave receiving groove 3, a lifting cylinder 5 connected to the top of the rotating platform 4, a lifting column 6 connected to the top of the lifting cylinder 5, and telescopic support parts 7 spaced apart on the top side of the lifting column 6, with different inspection fixtures 8 connected to the ends of the telescopic support parts 7. When the device is in operation, the torsion damper to be inspected is placed on the support inspection platform 2. Then, the rotating platform 4 on the side rotates the lifting cylinder 5 at a preset angle, thereby moving the inspection fixture 8 to a preset position. Subsequently, the lifting cylinder 5 descends, causing the lifting column 6 to descend, thus lowering the torsion damper to be inspected. The top inspection fixture 8 descends to a predetermined position for inspection. After the inspection is completed, the lifting cylinder 5 resets, and the rotating table 4 drives the lifting cylinder 5 to rotate at a preset angle again. The inspection fixture 8 at another station descends again for inspection. This process is repeated, and all the inspection fixtures 8 automatically move to the torsion damper to be inspected for inspection. There is no need for manual disassembly and assembly of the inspection fixtures 8. The inspectors only need to observe and make simple adjustments to the inspection fixtures 8 to carry out the inspection, which improves work efficiency. The rotating table 4 can be a rotating motor, which is located at the bottom of the workbench 1. The rotating shaft of the rotating motor is connected to the rotating base, which is located in the concave receiving groove 3 of the workbench 1. The top of the rotating base is connected to the lifting cylinder 5. The rotating table 4 can also adopt other existing technologies, which will not be described in detail here.

[0033] The support testing platform 2 includes a support plate 21 with symmetrically arranged concave grooves 22. Multiple first connecting posts 23 are symmetrically arranged in the middle of the top surface of the support plate 21. The first connecting posts 23 have connecting protrusions 24 on their sides. The first connecting posts 23 and connecting protrusions 24 correspond to the connecting holes of the torsion dampers to be tested. Before operation, the bottom of the torsion dampers to be tested can be manually aligned with the first connecting posts 23 and connecting protrusions 24 for installation. At this time, all the torsion dampers to be tested are in the same position, which is convenient for subsequent testing operations. The concave grooves 22 on both sides facilitate the placement and removal of the torsion dampers.

[0034] The lifting cylinder 5 is provided with a support platform 51 on its outer side. The four corners of the bottom of the support platform 51 are connected to the worktable 1 through support columns 52. The support platform 51 is provided with a sliding hole in the middle. The sliding hole is matched and connected to the lifting column 6. The lifting column 6 can slide up and down in the sliding hole of the support platform 51, thereby playing a certain limiting support role for the lifting column 6 and ensuring that the lifting column 6 rises and falls in the vertical direction.

[0035] The telescopic support 7 includes a first support plate 71, on the side of which a sliding groove 72 is formed. The sliding groove 72 is matched and connected to a second support plate 73. A fixing hole is formed on the outer side of the top of the sliding groove 72. A fixing block 74 is connected to the top of the fixing hole. A set screw 75 is internally threaded onto the fixing block 74. When the device is not working, the detection fixture 8 can be retracted inward to prevent workers from accidentally touching the end of the detection fixture 8 while working nearby, which could cause personal injury or damage to the instrument. The set screw 75 can be used to fix the second support plate 73 after it has been extended to a preset position.

[0036] The top of the support platform 51 is connected to the inner ring of the rotating bearing 56, and the outer ring of the rotating bearing 56 is connected to the rotating plate 53. The rotating plate 53 is provided with a concave limiting frame 54. The concave limiting frame 54 has symmetrical vertical sliding grooves 55 inside. The vertical sliding grooves 55 are matched and connected to the sliding protrusions on both sides of the first support plate 71. When the first support plate 71 slides up and down under the action of the lifting cylinder 5, it will slide vertically along the vertical sliding groove 55 to ensure that the testing fixture 8 and the torsion damper can make vertical contact for testing, thereby improving the accuracy of the test. When the lifting column 6 rotates, it will drive the rotating plate 53 to rotate along the rotating bearing 56. After the testing fixture 8 is lowered, it can also be finely adjusted manually so that the testing fixture 8 can perform testing on the torsion damper.

[0037] The testing fixture 8 includes a coaxiality tester 81, a spline tester 82, and a clearance hole tester 83. The coaxiality tester 81 includes a second connecting column 811, the bottom of which is connected to a third support plate 812. A drive motor 813 is mounted on the side of the third support plate 812. A central shaft 814 is connected to the bottom of the third support plate 812. The central shaft 814 is rotatably connected to a rotating disk 815. A first gear 816 is connected to the top of the rotating disk 815. The first gear 816 is matched with a second gear 817, which is mounted on the rotating shaft of the drive motor 813. A rotating roller 818 is connected to one side of the bottom of the rotating disk 815. A coaxiality testing plate 819 is rotatably connected to the central shaft 814. The rotating roller 818 can drive the coaxiality testing plate 819 to rotate, thus performing coaxiality testing. Instrument 81 can detect whether the outer shell of the torsion damper is coaxial after assembly by using the coaxiality detection plate 819. The coaxiality detection plate 819 is made according to the outer shell of the torsion damper and is existing technology, so it will not be described again. During operation, the lifting column 6 drives the coaxiality detection instrument 81 to descend until the central shaft 814 is inserted into the intermediate shaft hole of the torsion damper. Then the drive motor 813 starts to rotate. Through the meshing of the first gear 816 and the second gear 817, the rotating disk 815 is driven to rotate along the central shaft 814. When the rotating disk 815 rotates, it will drive the rotating roller 818 at the bottom to rotate. The rotating roller 818 will resist the coaxiality detection plate 819 to rotate around the torsion damper. If the coaxiality is not high, the drive motor 813 will have difficulty rotating. The staff next to it will stop and shut down the equipment for testing. The equipment is unqualified. Then the torsion damper is replaced and tested again.

[0038] The spline tester 82 includes a third connecting column 821, with a test column 822 at the bottom of the third connecting column 821 and a test gear at the end of the test column 822. The test gear matches the spline hole in the middle of the torsion damper. During testing, the lifting column 6 drives the second first connecting column 23 to descend, so that the test gear is aligned with the spline hole. The operator can rotate and adjust the test column 822. If the test gear cannot be inserted into the spline hole, the equipment is unqualified, and the torsion damper is then replaced and tested again.

[0039] The clearance hole detector 83 includes a fourth connecting column 831. The bottom of the fourth connecting column 831 is provided with a support roller 832. The bottom of the support roller 832 is connected to a detection support plate 833. The bottom of the detection support plate 833 has three corresponding insertion posts 834. The bottom of the insertion posts 834 has a concave slot 835. When clearance hole detection is required, the lifting column 6 drives the fourth connecting column 831 to descend. The angle of the detection support plate 833 can be adjusted appropriately by the operator so that the insertion posts 834 at the bottom are inserted into the clearance hole and engage with the first connecting column 23 at the bottom. If the concave slot 22 can be inserted into the first connecting column 23, it indicates that the clearance hole of the torsion damper is coaxial with the flywheel connection hole at the bottom, and the torsion damper is qualified, which facilitates the subsequent installation of the torsion damper. Otherwise, it indicates that it is unqualified.

[0040] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
