The telescopic rod of the cylinder 30 is connected to the hanging rod 31, which can drive the hanging rod 31 to move up and down (that is, the cylinder 30 is used to drive the hanging rod 31 to move up and down along the Z direction in the figure, and the Z direction is the height direction of the frame 10); the plurality of upper fixtures 20 can move in the length direction of the frame 10 (that is, the X direction in the figure). After the upper fixture 20 moves along the X direction, it can be hung and fixed together with the hanging rod 31, so that the upper fixture 20 is connected to the hanging rod 31, and the upper fixture can be driven by the cylinder 30. 20 moves downward so that the upper fixture 20 can move downward and dock with the vehicle thermal management module to be tested to test the vehicle thermal management module; a mounting seat 40 and a support rod 14 are provided on the frame 10, and multiple upper fixtures 20 are mounted on the mounting seat 40 and arranged along the length direction of the frame 10. Each upper fixture 20 is mounted on the mounting seat 40 through a first linear guide pair extending along the Z direction, so that the upper fixture 20 and the mounting seat 40 have the freedom to move in the height direction of the frame 10; the mounting seat 40 is mounted on the frame 10 through a second linear guide pair extending along the length direction of the frame 10, thereby, the mounting seat 40 can be used to drive the upper fixture 20 along the direction shown in the figure X-direction movement in the machine frame 10, specifically, the mounting seat 40 drives the upper clamp 20 to move in the length direction of the frame 10, so that the upper clamp 20 can move between a first position below the hanging rod 31 and a second position offset from the hanging rod 31; an avoidance groove 141 is provided on the support rod 14, which is recessed downward from its upper surface, and the avoidance groove 141 is located below the hanging rod 31; a hanging flange 32 is provided at the lower end of the hanging rod 31; a hanging seat 22 and a limit seat 23 are provided on the upper clamp 20, and a card slot 223 is provided on the hanging seat 22, and the card slot 223 forms an opening on the side of the hanging seat 22, or the card slot 223 forms an opening on both sides of the hanging seat 22, and the hanging rod 31 The hanging flange 32 can be inserted from the opening on the side of the card slot 223, so that the hanging flange 32 can be placed in the card slot 223, and the hanging rod 31 is connected to the hanging seat 22 by using the hanging flange 32 to cooperate with the hanging seat 22.

At this time, the limit seat 23 and the support rod 14 form a limit mechanism to prevent the upper clamp 20 from moving downward relative to the frame 10.
[0030] In the above structure of the utility model, a plurality of upper clamps 20 are arranged along the length direction of the frame 10 on the mounting seat 40. When the corresponding upper clamp 20 is needed, the mounting seat 40 is moved along the X direction, and the corresponding upper clamp 20 moves along the mounting seat 40 along the X direction toward the bottom of the hanging rod 31, so that the hanging flange 32 at the bottom of the hanging rod 31 can be inserted into the groove 223 from the side of the groove 223 at the top of the hanging seat 22, and the upper clamp 20 is connected to the telescopic rod of the cylinder 30, and the corresponding upper clamp 20 can be driven to move downward by the cylinder 30; when the upper clamp 20 needs to be replaced, the cylinder 30 drives the upper clamp 20 to move upward, and the mounting seat 40 moves along the X direction, driving the upper clamp 20 that needs to be replaced to move to the bottom of the hanging rod 31. Compared with the prior art, when replacing the clamp, the utility model only needs to use the horizontal movement of the mounting base to drive the corresponding upper clamp to move to the bottom of the hanging rod, so that the upper clamp is hung with the hanging rod, and the upper clamp can be quickly replaced, thereby improving the replacement efficiency of the upper clamp, and can make the replaced upper clamp directly in the position to be tested, thereby improving the testing efficiency of the automotive thermal management module, eliminating the need for hoisting, transferring and other processes on the upper clamp, and reducing labor costs.
[0031] In a preferred embodiment, the upper clamp 20 includes a clamp seat 21 and a plurality of detection rods 24 extending downward from the bottom surface of the clamp seat 21, wherein the hanging seat 22 is fixedly connected to the top surface of the clamp seat 21, and the hanging seat 22 includes two opposite side walls 221, the tops of the two side walls 221 are bent toward each other to form a limiting wall 222, and the slot 223 is surrounded by the two side walls 221 and the two limiting walls 222, and a through slot 224 for avoiding the hanging rod 31 is formed between the two limiting walls 222, and an opening is formed on both sides of the hanging seat 22 between the opposite edges of the two side walls 221. In this way, no matter whether the upper clamp 20 leans against the hanging rod 31 from the left or right side, the hanging flange 32 can be inserted into the slot 223. The above-mentioned limit seat 23 is fixedly connected to the rear side of the clamp seat 21, and the rear side surface of the limit seat 23 is provided with a guide groove 231 that is recessed forward, and the parts on the limit seat 23 located on the upper and lower sides of the guide groove respectively form a limit portion 232, and the support rod 14 slides in the limit groove 231 in front, and the two limit portions 232 are respectively located above and below the support rod 14, wherein the upper limit portion 232 is mounted on the upper surface of the support rod 14. When the upper clamp 20 is in a non-detection state, that is, when the upper clamp 20 is in the above-mentioned second position, the upper limit portion 232 cooperates with the support rod 14 to prevent the upper clamp 20 from moving downward relative to the frame 10. In addition, the lower limit portion 232 cooperates with the support rod 14 to prevent the upper clamp 20 from being disturbed by other factors and moving upward relative to the frame 10.

When the upper clamp 20 is located in the second position, the lower surface of the limit seat 23 and the bottom surface of the recess 401 are spaced apart by a distance D, that is, there is a certain distance between the limit seat 23 and the bottom surface of the recess 401. When the upper clamp 20 is replaced, the recess 401 corresponding to the upper clamp 20 moves to a position corresponding to the avoidance groove 141. At this time, the upper clamp 20 can move up and down relative to the mounting seat 40, and the recess 401 is used to provide an avoidance space for the limit seat 23 to move downward, so that the upper clamp 20 can move downward for a certain distance to test the vehicle thermal management module. The above-mentioned distance D is the maximum displacement that the upper clamp 20 can move downward. The first linear guide pair comprises two first linear guides 42 fixed on the mounting seat 40 and extending along the Z direction, and a first slider 421 slidably mounted on the two first linear guides 42 , and the fixture seat 21 of the upper fixture 20 is fixedly connected to the first slider 421 .

A positioning protrusion 151 is arranged on the positioning block 15, and the positioning protrusion 151 is clamped into the positioning groove 431. In this way, the positioning block 15 cooperates with the positioning seat 43 to limit the freedom of movement of the mounting seat 40 relative to the frame 10 in the X direction. When the upper fixture 20 needs to be replaced, the positioning block 15 is automatically loosened and separated from the positioning groove 431, and the mounting seat 40 can be moved along the X direction. When the upper fixture 20 is replaced, the positioning block 15 is fixed to the frame 10, and the positioning protrusion 151 on the positioning block 15 is clamped into the positioning groove 431 to prevent the mounting seat 40 from moving, thereby ensuring that the replaced upper fixture 20 can work normally.
[0034] Two mounting beams 11 extending along the length direction of the frame 10 are fixed on the frame 10, and the two mounting beams 11 are staggered with each other in the height direction of the frame 10; the second linear guide pair includes two second linear guides 12 respectively fixed on the two mounting beams, and a second slider 13 slidably mounted on the two second linear guides, and the mounting seat 40 is fixedly connected to the two second sliders 13. The support rod 14 is fixed on the upper mounting beam 11, and the support rod 14 is detachably fixed to the upper mounting beam 11 by bolts, and the support rod 14 is detachably fixed to the frame 10. When the support rod 14 is worn, a new support rod 14 can be replaced.
[0035] Two mounting longitudinal beams 103 are fixedly connected to the top of the frame 10. The mounting longitudinal beams 103 extend along the width direction of the frame 10 (i.e., the Y direction in the figure). The cylinder body of the cylinder 20 is fixed on a mounting plate 104. Both sides of the mounting plate 104 are overlapped and fixed on the two mounting longitudinal beams 103 respectively.
[0036] It should be pointed out that in the above scheme, the cylinder 20 is used as a driving member to drive the hook rod 31 to move up and down. In other embodiments, the driving member can also be an oil cylinder or other driving mechanism. In short, it can drive the hook rod 31 to move up and down.
[0037] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
