Technical Field
[0001] This utility model relates to the field of automotive interior parts testing technology, and in particular to a high and low temperature stiffness test bench. Background Technology
[0002] The stiffness of automotive interior components is a key indicator of a vehicle's comfort and durability. Effectively testing automotive stiffness under varying environmental temperatures has long been a challenge for the industry. Existing technologies and equipment often limit testing to room temperature and cannot perform tests under high and low temperature conditions. Laboratories typically employ a "high and low temperature storage + room temperature testing" approach, storing parts in high and low temperature environments for a period before immediately testing them at room temperature. However, because the testing environment is room temperature, the surface temperature of the parts changes rapidly, leading to poor accuracy of the test results. Furthermore, in existing technologies, the position of the testing head is relatively fixed, making it difficult to adjust the testing position, which also affects the results.
[0003] Therefore, we propose a high and low temperature stiffness test bench. Utility Model Content
[0004] The present invention aims to solve the technical problems existing in the prior art and provide a high and low temperature stiffness test bench.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high and low temperature stiffness test bench, comprising:
[0006] The base has a gantry frame fixedly installed on its top, and a detection head is provided on one side of the gantry frame.
[0007] An adjustment assembly is installed on the side wall of the gantry for adjusting the detection position. The adjustment assembly includes a vertical guide rail, a first slider, a horizontal guide rail, and a second slider. The vertical guide rail is fixedly installed on the gantry, the first slider is slidably connected to the vertical guide rail, the horizontal guide rail is fixedly connected to the first slider, and the second slider is slidably connected to the horizontal guide rail. Both the first slider and the second slider are fixed in position by the same first locking structure.
[0008] A mounting base assembly is disposed on the wall of the second slider for mounting the detection head. The mounting base assembly includes a base head, a thrust hole, and a limiting ring. The base head is rotatably connected to the second slider, and the limiting ring is elastically connected to the base head. A plurality of thrust holes are formed on the wall of the second slider, and the limiting ring can engage with the thrust holes.
[0009] In a preferred embodiment of this utility model, the first locking structure includes a socket and a positioning pin. The first slider and the second slider are slidably connected to the same positioning pin. The horizontal guide rail and the vertical guide rail are each provided with several identical sockets, and the positioning pin is inserted into the corresponding socket.
[0010] In a preferred embodiment of this utility model, the insertion hole is a round hole, and the positioning pin is used in conjunction with the insertion hole.
[0011] In a preferred embodiment of the present invention, the mounting base assembly further includes a protrusion, which is fixedly connected to a limiting ring and can be inserted into a thrust hole.
[0012] In a preferred embodiment of this utility model, the end face of the second slider is provided with a shaft hole, the seat head is rotatably disposed in the shaft hole, a clamp is installed on the end face of the seat head away from the second slider, and the detection head is fixedly installed in the clamp.
[0013] In a preferred embodiment of this utility model, the limiting ring forms a ring structure, the protrusion is located on the end face of the limiting ring and is integrally formed with the limiting ring, and the thrust holes at the end of the second slider are distributed in a ring array.
[0014] In a preferred embodiment of the present invention, the mounting base assembly further includes a guide block, which is fixedly connected to a limiting ring. A groove is provided radially on the wall of the base head, and the guide block is slidably disposed within the groove.
[0015] Beneficial effects
[0016] This utility model provides a high and low temperature stiffness test bench. It has the following beneficial effects:
[0017] 1. This high and low temperature stiffness test bench, by setting vertical and horizontal guide rails, allows the first slider to slide vertically along the vertical guide rail to adjust the detection height of the detection head, and the second slider to slide horizontally along the horizontal guide rail to adjust the horizontal position of the detection head. By inserting the insertion hole into the corresponding positioning pin, the positions of the second slider and the first slider can be locked, thereby locking the position of the detection head. It has multi-directional adjustment of the detection head position and does not need to be removed from the high and low temperature test chamber for use under high and low temperature conditions. Other tests can also be carried out directly in the high and low temperature test chamber, providing better flexibility in use.
[0018] 2. This high and low temperature stiffness test bench allows for adjustment of the detection head position by rotating the seat head. Before rotating the seat head, a limiting ring is pushed. A spring is fitted onto the seat head, and the limiting ring drives a guide block to slide within a groove. The limiting ring compresses the spring, causing the protrusion to disengage from the thrust hole. After rotating the seat head to a predetermined angle, the limiting ring is released, and the spring pushes the limiting ring back to its original position. The protrusion then engages with the corresponding thrust hole, thus locking the seat head angle. This provides a simple and quick way to lock the seat head position, while also allowing for other adjustments to the detection head position, making it convenient to operate and use.

[0025] A high and low temperature stiffness test rig, such as Figure 1 and Figure 2 As shown, it includes:
[0026] A base 10 is provided, and a gantry frame 11 is fixedly installed on the top of the base 10. A detection head is provided on one side of the gantry frame 11.
[0027] like Figure 2 and Figure 3 An adjustment assembly, located on the side wall of the gantry 11, is used to adjust the detection position. The adjustment assembly includes a vertical guide rail 12, a first slider 13, a horizontal guide rail 14, and a second slider 15. The vertical guide rail 12 is fixedly installed on the gantry 11. The first slider 13 is slidably connected to the vertical guide rail 12. The horizontal guide rail 14 is fixedly connected to the first slider 13. The second slider 15 is slidably connected to the horizontal guide rail 14. Both the first slider 13 and the second slider 15 are fixed in position by the same first locking structure. The first locking structure includes a socket 20 and a positioning pin 21. Both the first slider 13 and the second slider 15 are slidably connected to the same positioning pin 21. The horizontal guide rail 14 and the vertical guide rail 12 are provided with several identical sockets 20. The positioning pin 21 is inserted into the corresponding socket 20. The socket 20 is a round hole, and the positioning pin 21 and the socket 20 cooperate with each other.
[0028] In this solution, by setting a vertical guide rail 12 and a horizontal guide rail 14, the first slider 13 slides vertically along the vertical guide rail 12 to adjust the detection height of the detection head, and the second slider 15 slides horizontally along the horizontal guide rail 14 to adjust the horizontal position of the detection head. By inserting the insertion hole 20 into the positioning pin 21 at the corresponding position, the positions of the second slider 15 and the first slider 13 can be locked, thereby locking the position of the detection head. It has multi-directional adjustment of the position of the detection head. The detection head can be a pressure sensor, and the base 10 can be fixed in the high and low temperature chamber by bolts.
[0029] like Figure 3 , Figure 4 and Figure 5 As shown, a mounting base assembly is disposed on the wall of the second slider 15 for mounting the detection head. The mounting base assembly includes a seat head 16, a thrust hole 30, and a limiting ring 31. The seat head 16 is rotatably connected to the second slider 15, and the limiting ring 31 is elastically connected to the seat head 16. Several thrust holes 30 are formed on the wall of the second slider 15, and the limiting ring 31 can engage with the thrust holes 30. The mounting base assembly also includes a protrusion 32, which is fixedly connected to the limiting ring 31. The protrusion 32 can be inserted into the thrust hole 30. The protrusion 32 is a cylinder. The second slider 15... The end face is provided with a shaft hole, and the seat head 16 is rotatably set in the shaft hole. A clamp is installed on the end face of the seat head 16 away from the second slider 15. The detection head is fixedly installed in the clamp. The limiting ring 31 forms a ring structure. The protrusion 32 is located on the end face of the limiting ring 31 and is integrally formed with the limiting ring 31. The thrust holes 30 at the end of the second slider 15 are distributed in a ring array. The mounting seat assembly also includes a guide block 33. The guide block 33 is fixedly connected to the limiting ring 31. The wall surface of the seat head 16 is provided with a sliding groove along the radial direction. The guide block 33 is slidably set in the sliding groove.
[0030] The position of the detection head can be adjusted by rotating the seat head 16. Before rotating the seat head 16, push the limiting ring 31. The seat head 16 is fitted with a spring. The limiting ring 31 drives the guide block 33 to slide in the slide groove. The limiting ring 31 compresses the spring and deforms it. The protrusion 32 disengages from the thrust hole 30. After rotating the seat head 16 to the predetermined angle, release the limiting ring 31. The spring pushes the limiting ring 31 to reset. The protrusion 32 is inserted into the thrust hole 30 at the corresponding position, thereby locking the angle of the seat head 16. In addition to achieving another position adjustment of the detection head, locking the position of the seat head 16 is simple and quick, making it convenient to operate and use.
[0031] The working principle of this utility model is as follows: A vertical guide rail 12 and a horizontal guide rail 14 are set. The first slider 13 slides vertically along the vertical guide rail 12 to adjust the detection height of the detection head. The second slider 15 slides horizontally along the horizontal guide rail 14 to adjust the horizontal position of the detection head. By inserting the insertion hole 20 into the corresponding positioning pin 21, the positions of the second slider 15 and the first slider 13 can be locked, thereby locking the position of the detection head. The limiting ring 31 is pushed. The seat head 16 is fitted with a spring. The limiting ring 31 drives the guide block 33 to slide in the slide groove. The limiting ring 31 compresses the spring and deforms. The protrusion 32 disengages from the thrust hole 30. After rotating the seat head 16 to a predetermined angle, the limiting ring 31 is released. The spring pushes the limiting ring 31 to reset. The protrusion 32 is inserted into the corresponding thrust hole 30, thereby locking the angle of the seat head 16. This can realize the adjustment and fixation of the detection head height, horizontal position and circumferential angle to meet the detection of a variety of interior parts.
