Description

Technical Field

[0001] This utility model relates to the field of thyristor switch processing technology, and in particular to a thyristor switch test bench. Background Technology

[0002] As the application of thyristor switches becomes more widespread, it drives the progress and development of related processing industries. In addition, the production process requires the use of related testing equipment to detect whether the parts are qualified.

[0003] Chinese Patent Publication No. CN216848058U, published on 20220628, discloses a test bench for a thyristor switch, including a base, a limiting seat, and a limiting plate. The limiting seat is installed on the top of the base, and the limiting plate is installed on all four sides of the outer surface of the limiting seat. A limiting box is installed at the bottom of the base, and a motor box is installed on the inner top wall of the limiting box. A servo motor is installed inside the motor box, and a limiting screw is installed at the output end of the servo motor. A limiting sleeve is threaded to the outer surface of the limiting screw, and a limiting frame is provided on the top of the limiting sleeve.

[0004] Existing thyristor switch test benches, such as those described above, utilize a base, limit box, servo motor, limit screw, and limit slider. The rotation of the limit screw enhances the device's adjustability during use. Furthermore, the connecting rod on the limit frame, after being inserted into the rotating seat, provides both good rotational flexibility and easy disassembly. However, in practice, because the connecting rod is directly inserted into the rotating seat, it is prone to vertical jumping during rotation, affecting the stability of the thyristor switch test. Therefore, there is an urgent need to propose a corresponding thyristor switch test bench to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a test bench for thyristor switches in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A test bench for a thyristor switch includes a limit seat, a base, and a rotating tray. The base integrates a lifting platform and a lifting assembly for vertical movement of the lifting platform. The top of the lifting platform is rotatably connected to a rotating seat via a rotating shaft. The rotating tray is fixedly connected to the top of the rotating seat via a locking rod, and a constraint assembly is provided between the rotating seat and the rotating tray to limit the axial loosening of the locking rod.

[0008] Preferably, the lifting assembly includes a rotating component fixed to the inner wall of the bottom of the base, a transmission rod fixedly connected to the output end of the rotating component, a lifting sleeve fixedly connected to the bottom of the lifting platform screwed onto the outer wall of the transmission rod, and a limiting part for limiting the axial displacement of the lifting sleeve provided on the inner wall of the horizontal end of the guide plate.

[0009] Preferably, the limiting part includes a protrusion fixedly connected to the inner surface wall of the horizontal end of the guide plate, and the outer surface wall of the protrusion is slidably connected to the inner surface wall of the lifting sleeve through a vertical groove.

[0010] Preferably, the constraint assembly includes a rectangular block fixedly connected to the bottom of the rotating tray, the outer wall of the rectangular block engaging with the top of the rotating seat via a slot, and the inner wall of the rectangular block being screwed into a locking rod.

[0011] Preferably, the rectangular block is integrally formed with the bottom of the rotating tray.

[0012] Preferably, the top of the rotating tray is interference-fitted with a rubber stopper, and the bottom of the rubber stopper abuts against the top of the locking rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the rectangular block at the bottom of the rotating tray is integrated into the slot at the top of the rotating seat. By simultaneously screwing the rotating tray, the rectangular block, and the rotating seat together with the locking rod, the rotating seat and the rotating tray are fixed. This retains the axial rotation function of the lifting platform, while the rotating tray can be quickly disassembled and assembled by rotating the locking rod. Furthermore, the cooperation between the rectangular block and the slot can prevent the locking rod from loosening during the rotation of the rotating tray due to the coaxiality between the locking rod and the rotating plate, thus ensuring the stability of the rotating tray and improving the stability of the thyristor switch test bench.

[0015] 2. In this application, the rotating component drives the transmission rod to rotate, and the transmission rod provides a driving force to the lifting sleeve by engaging with the lifting sleeve. The protrusion on the inner surface of the guide plate and the mating block of the vertical groove can limit the axial deflection of the lifting sleeve. The lifting sleeve drives the rotating tray and the lifting platform to adjust the vertical position. The hollowed-out mating guide plate on the lifting platform can ensure the rapid transmission of unqualified products. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A test bench for a thyristor switch includes a limit seat 1, a base 2 and a rotating tray 4. The base 2 integrates a lifting platform 3 and a lifting assembly for vertical movement of the lifting platform 3. The top of the lifting platform 3 is rotatably connected to a rotating seat 13 via a rotating shaft. The rotating tray 4 is fixedly connected to the top of the rotating seat 13 via a locking rod 10. A constraint assembly is provided between the rotating seat 13 and the rotating tray 4 to limit the axial loosening of the locking rod 10.

[0025] The rectangular block 11 at the bottom of the rotating tray 4 is attached to the slot 12 at the top of the rotating seat 13. The rotating tray 4, the rectangular block 11 and the rotating seat 13 are simultaneously engaged by the locking rod 10, thereby fixing the rotating seat 13 and the rotating tray 4. While retaining the axial rotation function of the lifting platform 3, the rotating tray 4 can also be quickly disassembled and assembled by rotating the locking rod 10. Furthermore, the cooperation between the rectangular block 11 and the slot 12 can prevent the locking rod 10 from loosening during the rotation of the rotating tray 4 due to the coaxiality between the locking rod 10 and the rotating seat 13, thus ensuring the stability of the rotation of the rotating tray 4 and improving the stability of the thyristor switch test bench.

[0026] Specifically, such as Figure 2 and Figure 4As shown, the lifting assembly includes a rotating component 6 fixed to the inner wall of the bottom of the base 2. A transmission rod 7 is fixedly connected to the output end of the rotating component 6. A lifting sleeve 8, which is fixedly connected to the bottom of the lifting platform 3, is screwed onto the outer wall of the transmission rod 7. A limiting part is provided on the inner wall of the horizontal end of the guide plate 5 to limit the axial displacement of the lifting sleeve 8. The limiting part includes a protrusion fixedly connected to the inner wall of the horizontal end of the guide plate 5. The outer wall of the protrusion is slidably connected to the inner wall of the lifting sleeve 8 through a vertical groove 9. The rotating component 6 drives the transmission rod 7 to rotate. The transmission rod 7 provides a pushing force to the lifting sleeve 8 by screwing it onto the lifting sleeve 8. The cooperation between the protrusion on the inner wall of the guide plate 5 and the vertical groove 9 can limit the axial deflection of the lifting sleeve 8. The lifting sleeve 8 drives the rotating tray 4 to adjust the vertical position of the lifting platform 3. The hollow on the lifting platform 3, combined with the inclined surface of the guide plate 5, can ensure the rapid transmission of defective products.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the constraint assembly includes a rectangular block 11 fixedly connected to the bottom of the rotating tray 4. The outer wall of the rectangular block 11 engages with the top of the rotating seat 13 through a slot 12. The inner wall of the rectangular block 11 is screwed to the locking rod 10. Through the cooperation between the rectangular block 11 and the slot 12, the locking rod 10 can be prevented from loosening during the rotation of the rotating tray 4 due to the coaxiality between the locking rod 10 and the rotating seat 13. The rectangular block 11 and the bottom of the rotating tray 4 are integrally formed to ensure the connection strength between the rotating tray 4 and the rectangular block 11. A rubber plug is interference-fitted on the top of the rotating tray 4, and the bottom of the rubber plug abuts against the top of the locking rod 10. The interference fit ensures the stability of the rubber plug's position and the rubber plug can isolate the locking rod 10.

[0028] Working principle: The rectangular block 11 at the bottom of the rotating tray 4 is engaged with the slot 12 at the top of the rotating seat 13. Simultaneously, the rotating tray 4, the rectangular block 11, and the rotating seat 13 are screwed together by the locking rod 10, thus fixing the rotating seat 13 to the rotating tray 4. This retains the axial rotation function of the lifting platform 3, while allowing for quick assembly and disassembly of the rotating tray 4 by rotating the locking rod 10. Furthermore, the cooperation between the rectangular block 11 and the slot 12 prevents the locking rod 10 from becoming misaligned with the rotating seat 13. The loosening of the rotating tray 4 during rotation ensures the stability of the rotating tray 4, thereby improving the stability of the thyristor switch test bench. The rotating component 6 drives the transmission rod 7 to rotate. The transmission rod 7 provides a pushing force to the lifting sleeve 8 by engaging with the lifting sleeve 8. The cooperation between the protrusion on the inner wall of the guide plate 5 and the vertical groove 9 can limit the axial deflection of the lifting sleeve 8. The lifting sleeve 8 drives the rotating tray 4 and the lifting platform 3 to adjust their vertical positions. The hollow on the lifting platform 3, combined with the inclined surface of the guide plate 5, can ensure the rapid transmission of unqualified products.
