Description

Technical Field

[0001] This utility model relates to the field of triangular shaft technology, and in particular to a testing fixture for the production of universal triangular shafts. Background Technology

[0002] The universal three-way shaft consists of a swing rod, a sleeve, a shaft, and three rollers. The outer wall of the sleeve has three slots, and the end of the shaft is equipped with three rollers. The three rollers are embedded in the slots of the sleeve, and one end of the outer wall of the sleeve is connected to the swing rod through a bearing.

[0003] Before leaving the factory, the three-way shaft needs to undergo activity testing, which is usually done manually by the operator. However, since the direction of movement of the three-way shaft is not fixed and is random during operation, the operator cannot simulate the dynamics of the three-way shaft during operation by manually testing it a few times, and the accuracy of the test results is insufficient. Utility Model Content

[0004] The purpose of this application is to provide a testing fixture for the production of universal three-way shafts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A testing fixture for the production of a universal three-way shaft includes a support platform and a testing assembly mounted on the support platform. The testing assembly includes a mounting ring, a fixing plate, and a rotating plate. The mounting ring is fixedly mounted on the surface of the support platform. A fixing plate is fixedly mounted on the outer wall of one side edge of the mounting ring. Both the fixing plate and the rotating plate are arc-shaped curved plates. The end of the rotating plate is connected to the outer wall of the mounting ring via a bearing. The mounting direction of the fixing plate is perpendicular to the surface of the support platform, and the mounting direction of the rotating plate is parallel to the surface of the support platform. A groove is formed on the outer wall of the fixing plate, and a second magnetic ring is fixedly mounted on the inner wall of the rotating plate, passing through the groove.

[0007] Preferably, a second motor is mounted on the outer wall of one end of the rotating plate. The second motor is fixedly mounted on the support platform, and its output end is fixedly connected to the outer wall of the rotating plate. A sliding cylinder is fixedly mounted on the bottom of the support platform. A moving groove is formed on the surface of the support platform. A moving plate is fixedly mounted on the output end of the sliding cylinder. The moving plate is installed inside the moving groove, and a first motor is fixedly mounted on the top of the moving plate. The output end of the first motor faces the mounting ring, and a first magnetic ring is fixedly mounted on the output end of the first motor. The mounting height of the first magnetic ring corresponds to that of the second magnetic ring.

[0008] The beneficial effects of this utility model are: by setting up a test component, the reagent working conditions of the triangular shaft can be simulated from multiple angles, and the triangular shaft can be tested from multiple angles, thereby improving the accuracy of the test results.

[0013] like Figure 1-2 The test fixture shown includes a support platform 1 and a test assembly mounted on the support platform 1. The test assembly includes a mounting ring 3, a fixing plate 4, and a rotating plate 5. The mounting ring 3 is fixedly mounted on the table surface of the support platform 1. The fixing plate 4 is fixedly mounted on the outer wall of one side edge of the mounting ring 3. Both the fixing plate 4 and the rotating plate 5 are arc-shaped curved plates. The end of the rotating plate 5 is connected to the outer wall of the mounting ring 3 through a bearing. The mounting direction of the fixing plate 4 is perpendicular to the table surface of the support platform 1, and the mounting direction of the rotating plate 5 is parallel to the table surface of the support platform 1. The outer wall of the fixing plate 4 is provided with a sliding groove 6. A magnetic ring 12 is fixedly mounted on the inner wall of the rotating plate 5, and the magnetic ring 12 passes through the sliding groove 6.

[0014] A second motor 9 is mounted on the outer wall of one end of the rotating plate 5. The second motor 9 is fixedly mounted on the support platform 1, and its output end is fixedly connected to the outer wall of the rotating plate 5. A sliding cylinder 10 is fixedly mounted on the bottom of the support platform 1. A moving groove 2 is provided on the surface of the support platform 1. A moving plate 8 is fixedly mounted on the output end of the sliding cylinder 10. The moving plate 8 is installed inside the moving groove 2, and a first motor 7 is fixedly mounted on the top of the moving plate 8. The output end of the first motor 7 is mounted facing the mounting ring 3, and a first magnetic ring 11 is fixedly mounted on the output end of the first motor 7. The mounting height of the first magnetic ring 11 corresponds to that of the second magnetic ring 12.

[0015] Example: The end of the universal three-way shaft is attracted and fixed inside the magnetic ring 11. Then, the slide cylinder 10 is started. The output end of the slide cylinder 10 drives the moving plate 8 to slide in the moving groove 2 and move towards the mounting ring 3. The motor 7 on the top of the moving plate 8 moves accordingly, driving the swing rod of the three-way shaft to approach the magnetic ring 12. The end of the swing rod is attracted and fixed inside the magnetic ring 12. Then, the motor 9 drives the rotating plate 5 to rotate. The rotating plate 5 drives the magnetic ring 12 to slide in the sliding groove 6 of the fixed plate 4. The magnetic ring 12 drives the swing rod to move up and down. The operator can directly observe the swing of the swing rod.

[0016] The motor 7 on the support platform 1 can drive the shaft to rotate, and the shaft drives the sleeve to rotate, causing the rollers fitted in the sleeve to change their position. After changing their position, the motor 9 drives the rotating plate 5 to rotate again, so that the swing rod can drive the rollers in different positions to rotate, making it convenient for the operator to observe the movement of different rollers.

[0017] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.

[0018] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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.
