Description

Technical Field

[0001] This utility model relates to the field of testing fixtures, specifically to a vibration testing fixture for a DHT hydraulic control module. Background Technology

[0002] The hydraulic control module plays a crucial role in a hydraulic system, directing the various actions of the hydraulic actuators. For the DHT hydraulic control module, its performance directly affects the stability and efficiency of the entire hydraulic system. The DHT hydraulic control module is a highly integrated and high-precision hydraulic control system that achieves precise control of mechanical motion by accurately controlling the parameters of the hydraulic fluid. This type of module plays an important role in modern industrial automation. Vibration testing can evaluate the performance stability of the DHT hydraulic control module under vibration environments. In actual use, the module may be affected by various vibrations, such as the bumps and vibrations of a vehicle in motion. If the module's performance is unstable under vibration environments, it may lead to inaccurate hydraulic control and affect the normal operation of the entire system.

[0003] The existing vibration testing fixtures still have the following problems when used: the current DHT control module is relatively small in size, which means that only one set of modules can be tested at a time, resulting in low testing efficiency.

[0004] Therefore, it is necessary to invent a vibration testing fixture for a DHT hydraulic control module to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a vibration testing fixture for DHT hydraulic control modules, in order to solve the problem mentioned in the background art that the current DHT control modules are small in overall size, which means that only one set of modules can be tested at a time, resulting in low testing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration testing fixture for a DHT hydraulic control module, comprising a base plate, an upright plate inserted into the base plate, and a threaded groove I inside the upright plate, with a threaded rod threadedly connected inside the threaded groove I. A mounting piston is threadedly connected to the side of the upright plate via the threaded rod. A threaded groove II inside the mounting piston is threadedly connected to the threaded rod, and a shift fork is mounted on the mounting piston. The threaded rod is anti-disengaged from the threaded groove I via an anti-disengagement component, and a saw gear is fixedly mounted at the end of the threaded rod.

[0007] Preferably, the two upright plates are arranged side by side with a gap between them, and the two upright plates are symmetrically arranged with reference to the central axis of the base plate. This allows for simultaneous vibration testing of two sets of modules, ensuring the efficiency of the operation.

[0008] Preferably, the two threaded rods are arranged side by side on the upright plate, with a total of two sets of threaded rods on each upright plate. The two threaded rods are arranged symmetrically with reference to the central axis of the upright plate as the left and right axis, and the outer threads of the two threaded rods have different directions.

[0009] Preferably, two saw gears fixedly installed at the ends of the two threaded rods are symmetrically arranged with reference to the central axis of the upright plate as the axis of symmetry, and the two saw gears are meshed together. In this way, turning one of the saw gears will cause the two threaded rods arranged side by side to rotate in opposite directions, so that the two threaded rods rotate synchronously and move in the same direction inside the first and second threaded grooves. After the two threaded rods move in the same direction and leave the second threaded groove, the installation piston can be removed and threadedly connected to another set of threaded rods at different height positions, which facilitates the adjustment of the height position of the shift fork.

[0010] Preferably, the anti-detachment component includes an annular groove disposed inside the upright plate and communicating with the threaded groove, and an annular block is rotatably installed inside the annular groove. The limiting block fixedly installed on the inner wall of the annular block is slidably connected with the limiting transverse groove provided on the threaded rod. In this way, the movement of the threaded rod and the inside of the threaded groove is restricted, so as to prevent the threaded rod and the threaded groove from falling off and affecting the subsequent connection between the piston and the upright plate.

[0011] Preferably, the two limiting blocks are arranged symmetrically on the inner ring wall of the annular block with the central axis of the annular block as the reference. The outer wall of the limiting block is attached to the inner wall of the limiting transverse groove to achieve a sliding connection, and both ends of the limiting transverse groove are closed.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. The shift fork is pushed by the piston installed at the end and limits the module to be tested. In this way, two products can be carried in one vibration test, which can greatly save the test cost and help control the cost. Turning one of the saw gears rotates and moves two threaded rods arranged side by side in opposite directions. This causes the two threaded rods to rotate synchronously and move in the same direction inside the first and second threaded grooves. After the threaded rods have completely moved out of the second threaded groove in the same direction, the installation piston can be removed and connected to another set of threaded rods at different heights to achieve threaded connection. This facilitates the adjustment of the height position of the shift fork. The synchronous movement of the two threaded rods in the side by side results in high disassembly and assembly efficiency. 2. When the threaded rod rotates and moves, the sliding connection between the limiting block and the limiting transverse groove is restricted. The limiting block and the limiting transverse groove at both ends are in a closed state to achieve a non-detached connection. This ensures that the threaded rod and the threaded groove are connected without detachment, preventing the threaded rod from falling and being lost after twisting. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-4 The vibration testing fixture for a DHT hydraulic control module shown includes a base plate 1, on which a vertical plate 2 is inserted. The vertical plate 2 has a threaded groove 6 inside, and a threaded rod 5 is threadedly connected inside the threaded groove 6. A mounting piston 3 is threadedly connected to the side of the vertical plate 2 via the threaded rod 5. A pre-set threaded groove 7 inside the mounting piston 3 is threadedly connected to the threaded rod 5. A shift fork 4 is mounted on the mounting piston 3. The threaded rod 5 is anti-detached from the threaded groove 6 via an anti-detachment component 9. A saw gear 8 is fixedly mounted at the end of the threaded rod 5. The shift fork 4 is pushed by the end-mounted piston 3 and limits the module under test. In this way, two products can be mounted in one vibration test, which can greatly save the test cost and help control costs.

[0018] In use, rotating one of the saw gears 8 causes the two parallel threaded rods 5 to rotate in opposite directions, resulting in the two threaded rods 5 rotating synchronously and moving in the same direction inside the first threaded groove 6 and the second threaded groove 7. After the two threaded rods 5 have completely moved out of the second threaded groove 7, the mounting piston 3 can be removed and threadedly connected to another set of threaded rods 5 at different heights, which facilitates the adjustment of the height of the shift fork 4.

[0019] Two upright plates 2 are arranged side by side with intervals, and the two upright plates 2 are symmetrically arranged with reference to the central axis of the base plate 1. In this way, two products can be carried in one vibration test, which can greatly save the test cost and help control costs.

[0020] Two threaded rods 5 are arranged side by side on the vertical plate 2. Each vertical plate 2 has two sets of threaded rods 5, one upper and one lower. The two threaded rods 5 are symmetrical about the central axis of the vertical plate 2, and the outer threads of the two threaded rods 5 have different directions. Two saw gears 8 are fixedly installed at the ends of the two threaded rods 5, and are symmetrical about the central axis of the vertical plate 2. The two saw gears 8 are meshed. Turning one saw gear 8 will drive the other pre-meshed saw gear 8 to rotate in different directions, thereby causing the two threaded rods 5 arranged side by side to rotate in different directions. Because the two threaded rods 5 are arranged side by side with different directions, the two threaded rods 5 that are threaded to the first threaded groove 6 and the second threaded groove 7 will move in the same direction when they rotate.

[0021] By rotating one of the saw gears 8, the two parallel threaded rods 5 rotate in opposite directions, causing them to rotate synchronously and move in the same direction within the threaded groove 1 6 and the threaded groove 2 7. After the two threaded rods 5 move out of the threaded groove 2 7 in the same direction, the mounting piston 3 can be removed and threadedly connected to another set of threaded rods 5 at different heights, facilitating the adjustment of the height of the shift fork 4.

[0022] The anti-detachment component 9 includes an annular groove 901 disposed inside the upright plate 2 and communicating with the threaded groove 6. An annular block 902 is rotatably mounted inside the annular groove 901. A limiting block 903 fixedly mounted on the inner annular wall of the annular block 902 is slidably connected to a limiting transverse groove 904 provided on the threaded rod 5. This restricts the movement of the threaded rod 5 and the threaded groove 6, preventing the threaded rod 5 and the threaded groove 6 from falling off and affecting the subsequent connection between the piston 3 and the upright plate 2. The two limiting blocks 903 are a set and are symmetrically arranged on the inner annular wall of the annular block 902 with reference to the central axis of the annular block 902. The outer wall of the limiting block 903 is attached to the inner wall of the limiting transverse groove 904 to achieve a sliding connection. Both ends of the limiting transverse groove 904 are closed.

[0023] When the threaded rod 5 rotates, the limiting block 903, which is slidably installed in the upper limit transverse groove 904 of the threaded rod 5, causes the annular block 902 to rotate synchronously in the annular groove 901. In this way, the rotation of the threaded rod 5 is not affected. At the same time, when the threaded rod 5 moves, the limiting block 903 and the limiting transverse groove 904 are slidably connected, so that the position movement of the threaded rod 5 is not affected. At the same time, the sliding connection between the limiting block 903 and the limiting transverse groove 904 is restricted, and the limiting block 903 and the limiting transverse groove 904, which are in a closed state at both ends, are connected without falling off. This ensures that the threaded rod 5 and the threaded groove 6 are connected without falling off, avoiding the threaded rod 5 from falling off and being lost after twisting.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
