Technical Field

[0001] This utility model relates to the field of production and testing technology for top adhesive bushings, and in particular to a testing fixture for top adhesive bushings. Background Technology

[0002] Automotive top mount bushings (also known as shock absorber top mounts, suspension top mounts, or buffer bushings) are crucial components of automotive suspension systems, primarily used for shock absorption, cushioning, noise reduction, and supporting suspension system movement. Automotive top mount bushings consist of an elastic element and a metal frame. Before leaving the factory, the elastomer of the automotive top mount bushing undergoes a series of rigorous tests to ensure its durability, mechanical properties, and reliability, including multi-dimensional tests of mechanical properties, environmental durability, fatigue life, and adhesive strength. One test involves applying a certain force to the elastic element to test its adhesion within the frame housing.

[0003] Existing testing equipment requires operators to manually load and unload materials one by one, and to frequently operate under the pressure components. Due to the limited space, there is a risk of operational errors, which can lead to hand injuries to operators and affect testing efficiency and safety. Utility Model Content

[0019] Figure 2 This is a schematic diagram of the connection structure of the moving board;

[0020] Figure 3 This is a schematic diagram of the material placement component structure;

[0021] Figure 4 This is a schematic diagram of the bushing structure. Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1As shown, a bushing testing fixture for top adhesive of this utility model includes a worktable 1, a movable plate 2, a material placement component 3, a pressure rod 4, and a driving component 5;

[0024] The movable plate 2 is located on the workbench 1, and the number of material placement components 3 is one or more. The material placement components 3 are located on the movable plate 2, such as... Figure 3 As shown, the top of the material placement component 3 is provided with a material placement groove 31; as Figure 2 As shown, the workbench 1 is provided with a positioning block 12, and the positioning block 12 is provided with a positioning groove 121, which faces the corner of the moving plate 2.

[0025] The pressure rod 4 is vertically arranged above the moving plate 2. The pressure rod 4 is connected to the driving component 5. The number of pressure rods 4 is matched with the number of material placement components 3.

[0026] This utility model provides a bushing testing fixture for top adhesive, such as... Figure 4 As shown, the bushing 7 has an elastic element 71 inside. The moving plate 2 is pulled to the material feeding station, which is away from the test station, and the bushing 7 is placed on the material placement component 3 to position the bushing 7 and prevent it from being misaligned with the pressure rod 4 due to inaccurate placement, which would affect the test. The moving plate 2 is then pushed to the test station, and the corner of the moving plate 2 abuts against the positioning groove 121 of the positioning block 12, so that the bushing 7 is directly below the corresponding pressure rod 4. The driving component 5 can be an existing cylinder, which controls the pressure rod 4 to press down the elastic element 71 inside the corresponding bushing 7, thereby testing the bonding strength of the elastic element 71. After the test is completed, the moving plate 2 is pulled out of the test station, which makes it convenient for the staff to quickly and safely remove the material.

[0027] A linear guide rail assembly 11 is provided between the movable plate 2 and the worktable 1. The linear guide rail assembly 11 can be an existing combination of slider and straight rail, which guides the back and forth movement of the movable plate 2, so that the movable plate 2 always moves along the same straight line, avoiding misalignment and causing the test position to shift.

[0028] The positioning block 12 is a magnetic block. When the moving plate 2 is pushed to the test station, the positioning block 12 comes into contact with the moving plate 2 and magnetically attracts the moving plate 2, which further positions the moving plate 2. This prevents the moving plate 2 from being significantly misaligned due to the influence of the slider after the force is released, thus avoiding affecting the connection between the pressure rod 4 and the bushing 7.

[0029] The movable plate 2 is equipped with a lever 23 on its side, which allows the operator to push and pull the movable plate 2, improving the convenience and safety of operation.

[0030] The material placement groove 31 of the material placement component 3 is used to place the bushing 7. The bottom of the material placement groove 31 is provided with a pad 32. When the pressure rod 4 applies a certain force downward to the bushing 7, the bottom of the bushing 7 is squeezed to the bottom of the material placement groove 31. The pad 32 can be made of soft rubber material, which plays a certain protective role for the metal shell of the bushing 7 and avoids the metal shell from being indented.

[0031] The movable plate 2 is provided with a connecting groove 21, and the bottom of the connecting groove 21 is provided with a connecting hole 22. The bottom of the material placement component 3 is provided with a first fastener 33. The material placement component 3 is detachably connected to the connecting groove 21 through the first fastener 33 and the connecting hole 22. Depending on the size of the bushing 7, the material placement component 3 can be quickly disassembled and replaced through the first fastener 33 to improve the test applicability.

[0032] A connecting ring 6 is provided between the pressure rod 4 and the driving component 5. The pressure rod 4 has a vertical mounting groove 41, and the connecting ring 6 has a mounting hole 62. The second fastener 61 connects the pressure rod 4 to the bottom of the connecting ring 6 through the mounting hole 62 and the mounting groove 41. According to testing requirements, the initial height of the pressure rod 4 can be adjusted by selecting different installation positions of the mounting groove 41. Alternatively, a matching pressure rod 4 can be replaced according to the different sizes of the bushing 7.

[0033] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
