Description

Technical Field

[0001] This utility model relates to the technical field of shaft performance testing equipment, specifically to a device for testing the performance of an automotive starter motor armature shaft. Background Technology

[0002] The armature shaft provides support for the armature core, armature windings, and commutator, ensuring their stable rotation during starter operation. It also transmits the electromagnetic torque generated by the armature windings to the starter's transmission mechanism, thereby driving the engine flywheel to rotate and starting the engine.

[0003] Because of the importance of the armature shaft, its quality requirements are very high. Therefore, it is necessary to test the manufactured armature shafts. However, current testing equipment has limited functionality and is not easy to adjust, lacking flexibility in clamping and positioning shafts of different diameters. Therefore, this paper proposes a performance testing device for automotive starter motor armature shafts. Utility Model Content

[0004] The technical problem this invention aims to solve is that current testing equipment has limited functionality and is not easily adjustable, resulting in poor flexibility in clamping and positioning shafts of different diameters. This invention provides a performance testing device for automotive starter armature shafts, enabling simultaneous testing of two performance parameters, facilitating the replacement of different testing components as needed, and allowing for flexible adjustment and clamping positioning of shafts of different sizes.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a vehicle starter armature performance testing device, including a base, a door panel fixedly connected to the top side wall of the base, an adjustment groove through the top side wall of the door panel, three connecting blocks slidably connected in the adjustment groove, a lifting telescopic rod detachably connected to the middle of the bottom side wall of each connecting block, and a dial indicator and a roughness tester detachably connected to the output end of the lifting telescopic rod, respectively, with two roughness testers provided and located on both sides of the dial indicator.

[0006] As a preferred technical solution of this utility model, a movable groove is provided in the middle of the top side wall of the base, and a threaded rod is rotatably connected in the movable groove. The threaded rod has a bidirectional thread structure. A vertical plate is provided on the top side wall of the base located in the movable groove. A slider is fixed at the bottom end of the vertical plate, and the slider is threadedly sleeved on the threaded rod. A driver is detachably connected to one side wall of the base, and the output end of the driver is detachably connected to one end of the threaded rod.

[0007] As a preferred technical solution of this utility model, a clamping plate is rotatably connected to the opposite sidewalls of the two vertical plates, and a motor is detachably connected to the top sidewall of one of the vertical plates. The output end of the motor passes through the vertical plate and is detachably connected to one sidewall of the clamping plate.

[0008] As a preferred technical solution of this utility model, the inner wall of the clamping plate is provided with insertion steps in stages, and the side wall of each insertion step is fixed with an anti-slip rubber pad. A screw is threadedly connected to the side wall of the clamping plate near the opening, and a positioning arc plate is rotatably connected to one end of the screw extending into the interior of the clamping plate. The inner wall of the positioning arc plate is connected with an anti-slip rubber pad.

[0009] As a preferred technical solution of this utility model, the base has a moving groove on the top and on both sides of the moving groove. A displacement block is slidably connected in the moving groove, and the displacement block is detachably connected to a follower plate through the top end. A bottom groove is formed in the follower plate. A top support telescopic rod is detachably connected to the bottom side wall of the bottom groove. A support plate is detachably connected to the output end of the top support telescopic rod. A wear plate is detachably connected to the top side wall of the support plate.

[0010] This utility model has the following advantages: The corresponding testing equipment is connected to the top of the door panel through a connecting block. The bending degree of the armature shaft can be detected by the dial indicator, while the surface roughness and wear resistance of the armature shaft can be detected by the roughness tester at both ends. The wear plate is attached to one end of the armature shaft. By rotating the armature shaft, the wear resistance can be obtained by comparing the test data of the corresponding roughness tester with the test data of the roughness tester at the other end. Different testing equipment can be replaced and connected to the lifting telescopic rod when needed, so as to achieve the effect of multiple tests being performed simultaneously by one device, thereby improving the functionality of the test.

[0011] By creating multiple layers of insertion steps within the clamping plate, it can accommodate armature shafts of different diameters, effectively positioning both ends of the armature shaft. In conjunction with a positioning arc plate driven by a screw, the armature shaft is clamped, thus driving the armature shaft to smoothly rotate with the clamping plate, thereby enabling the armature shaft to be inspected.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 This utility model discloses a device for testing the performance of an automotive starter armature, comprising a base 1, a door panel 2 fixedly connected to the top side wall of the base 1, an adjustment groove 3 extending through the top side wall of the door panel 2, three connecting blocks 4 slidably connected within the adjustment groove 3, and a lifting telescopic rod 5 detachably connected to the middle of the bottom side wall of each connecting block 4, the output end of the lifting telescopic rod 5 being detachably connected to a dial indicator 6 and a roughness tester 7, and two roughness testers 7 being provided on both sides of the dial indicator 6.

[0018] The technical effects of this solution are as follows: As needed, the corresponding testing tools are connected to the output end of the lifting telescopic rod 5. After the armature shaft is positioned, the lifting telescopic rod 5 is activated to lower the dial indicator 6. The probe at the bottom of the dial indicator 6 contacts the surface of the armature shaft. By driving the armature shaft to rotate, the curvature of the armature shaft is determined based on the change in the value on the dial indicator 6 during rotation. Similarly, the roughness tester 7 is lowered so that its probe contacts the armature shaft. Roughness is then detected by rotation. The two roughness testers 7 can simultaneously detect the roughness at both ends of the armature shaft, improving the accuracy of the test. Because the connecting block 4 is movable, the entire area of ​​the armature shaft can be tested, improving the reliability and flexibility of the test.

[0019] A movable groove 11 is formed in the middle of the top side wall of the base 1, and a threaded rod is rotatably connected within the movable groove 11. The threaded rod has a bidirectional threaded structure. A vertical plate 8 is provided on the top side wall of the base 1 located in the movable groove 11. A slider is fixed to the bottom end of the vertical plate 8, and the slider is threaded onto the threaded rod. A driver is detachably connected to one side wall of the base 1, and the output end of the driver is detachably connected to one end of the threaded rod. A clamping plate 10 is rotatably connected to the opposite side walls of the two vertical plates 8. A motor 9 is detachably connected to the top side wall of a vertical plate 8. The output end of the motor 9 passes through the vertical plate 8 and is detachably connected to one side wall of the clamping plate 10. The inner wall of the clamping plate 10 is provided with a series of insertion steps 17. Each layer of insertion steps 17 has a non-slip rubber pad fixed to its side wall. A screw 18 is threadedly connected to the side wall of the clamping plate 10 near the opening. The end of the screw 18 that extends into the interior of the clamping plate 10 is rotatably connected to a positioning arc plate 19. The inner wall of the positioning arc plate 19 is connected to a non-slip rubber pad.

[0020] The technical effect of this solution is as follows: To accommodate armature shafts of different sizes, multiple insertion steps 17 are provided inside the clamping plate 10. These insertion steps 17 gradually decrease in size, so that the ends of armature shafts of different diameters can be inserted into the corresponding insertion steps 17, improving the positioning effect of the armature shaft. The driver is started to drive the bidirectional threaded rod to rotate, thereby adjusting the spacing of the clamping plate 10 to accommodate armature shafts of different lengths, improving the overall flexibility of the equipment. In conjunction with the screw 18 driving the positioning arc plate 19 to clamp the end of the armature shaft, when the motor 9 drives the clamping plate 10 to rotate, it can drive the armature shaft to rotate smoothly, thereby performing testing.

[0021] The base 1 has a moving groove 11 on its top and on both sides of the moving groove 11. A displacement block is slidably connected in the moving groove 11, and a follower plate 12 is detachably connected to the top of the displacement block. A bottom groove 15 is provided in the follower plate 12. A top support telescopic rod 16 is detachably connected to the bottom side wall of the bottom groove 15. A support plate 14 is detachably connected to the output end of the top support telescopic rod 16. A wear plate 13 is detachably connected to the top side wall of the support plate 14.

[0022] The technical effect of this solution is as follows: Activating the top support telescopic rod 16 adjusts the connecting block 4 and the wear plate 13 to a suitable position, ensuring that the wear plate 13 is in contact with the surface of the armature shaft. Before this, the follower plate 12 is moved to a suitable position along the moving groove 11. At the same time, the corresponding roughness meter 7 is adjusted to a position opposite to the wear plate 13. Then, the armature shaft is driven to rotate. The contact between the armature shaft and the wear plate 13 will cause friction on the surface of the armature shaft. By comparing the roughness of the friction position with the roughness of the non-friction position, and in combination with the running time, the wear resistance of the armature shaft can be tested.

[0023] Specifically, in use, the armature shaft to be tested is placed between two clamping plates 10. Then, the drive screw is rotated to clamp the armature shaft. The rotating screw 18 drives the positioning arc plate 19 to clamp the armature shaft a second time, ensuring the stability of the armature shaft and allowing it to rotate smoothly. The follower plate 12 is pre-adjusted to a suitable position, and the corresponding connecting block 4 is adjusted accordingly to adjust the dial indicator 6 and roughness tester 7 to a suitable position. Then, the lifting telescopic rod 5 is activated to lower the dial indicator 6 and roughness tester 7 so that their probes are in contact with the surface of the armature shaft. The top support telescopic rod 16 is activated to drive the wear plate 13 to contact the armature shaft. Then, the motor 9 drives the armature shaft to rotate, first at full speed, to detect the curvature of the armature shaft. After that, the dial indicator 6 is raised and then rotated quickly, and the roughness and wear resistance are tested in conjunction with the wear plate 13 and the roughness tester 7.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
