Detailed implementation manners

[0023] In order to enable those skilled in the art of this technology to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 4 shown, an inspection fixture for an automotive instrument assembly in an embodiment of the present utility model, the instrument includes an instrument body 24, a group of fixing ears 25 are fixedly connected to the instrument body 24, and a second fixing hole 26 is provided in the fixing ears 25. A first detection plate 21 is arranged inside the fixed plate 11, and a plurality of support legs 12 are fixedly connected to the bottom of the fixed plate 11. A plurality of detection grooves 22 matching the instrument body 24 are provided inside the first detection plate 21.

[0025] A first fixing hole 23 is arranged inside the detection groove 22, a second detection plate 31 is arranged above the fixed plate 11, a plurality of positioning holes 32 corresponding to the first fixing holes 23 are provided inside the second detection plate 31, a detection rod 33 is arranged inside the positioning holes 32, and a lifting structure is arranged between the second detection plate 31 and the fixed plate 11.

[0026] Specifically, the detection slot 22 and the first fixing hole 23 correspond to the installation positions on the vehicle body. The instrument main body 24 can be fixed in the detection slot 22. The second fixing hole 26 is aligned with the first fixing hole 23 under normal circumstances, that is, the second fixing hole 26 is aligned with the fixing hole on the vehicle body. The second detection plate 31 can move up and down, thereby driving the detection rod 33 to move up and down. The detection rod 33 matches the first fixing hole 23, the detection rod 33 matches the second fixing hole 26, and the detection rod 33 can pass through the second fixing hole 26 and the first fixing hole 23, then the second fixing hole 26 is aligned with the first fixing hole 23.

[0027] When the second fixing hole 26 is not aligned with the first fixing hole 23, the position of the second fixing hole 26 is deviated, the detection rod 33 cannot move downward, the detection rod 33 will abut against the fixing ear 25, and the remaining detection rods 33 will continue to move downward. The detection rod 33 that cannot move downward will protrude from the upper end surface of the second detection plate 31 as the second detection plate 31 moves. After the detection, move the second detection plate 31 upward, and the second fixing hole 26 corresponding to the protruding detection rod 33 represents a deviation in position, which is convenient for detecting the positions of the second fixing holes 26 on multiple instrument main bodies 24 at the same time.

[0028] A limiting slot 28 is provided in the first detection plate 21. A limiting plate 27 that matches the limiting slot 28 is fixedly connected to the fixing plate 11. A pull rod 29 is fixedly connected to the first detection plate 21. There can be multiple first detection plates 21, which is convenient for installing and disassembling the instrument main body 24 in the first detection plate 21. Through the pull rod 29, it is convenient to pull out the detected first detection plate 21, and then install the undetected first detection plate 21 in the fixing plate 11, which can increase the detection speed.

[0029] A limiting frame 41 is fixedly connected to the fixing plate 11. An insertion plate 42 is arranged in the limiting frame 41. The insertion plate 42 is located in the limiting frame 41, and the insertion plate 42 can move to a position where it abuts against the first detection plate 21 to prevent the first detection plate 21 from shifting outward and affecting the detection accuracy.

[0030] Anti-slip lines are provided in the positioning hole 32. The detection rod 33 can slide in the positioning hole 32 with resistance. In the initial state, the upper end surface of the detection rod 33 is flush with the upper end surface of the second detection plate 31. When the detection rod 33 moves into the second fixing hole 26 and the first fixing hole 23, it can prevent the detection rod 33 from moving upward and protruding from the positioning hole 32 when contacting the inner walls of the second fixing hole 26 and the first fixing hole 23 and generating resistance, which affects the detection.

[0031] The lifting structure includes a shaft rod 13 fixedly connected to the fixed plate 11 and a threaded rod 14 rotatably connected to the fixed plate 11. A limiting hole 34 matching the shaft rod 13 is formed in the second detection plate 31, and a threaded hole 35 matching the threaded rod 14 is formed in the second detection plate 31. A bearing 15 is fixedly connected between the threaded rod 14 and the fixed plate 11, and a handle 16 is fixedly connected to the bottom end of the threaded rod 14. By rotating the handle 16, it is convenient to drive the threaded rod 14 to rotate, so as to move the second detection plate 31 up and down for detection. A limiting block 17 is fixedly connected to the fixed plate 11, and the second detection plate 31 can be limited by the limiting block 17 to prevent the bottom end surface of the second detection plate 31 from contacting the instrument main body 24 and causing wear to the instrument main body 24.

[0032] A rubber hammer 37 is arranged on the second detection plate 31. A fixing part 36 is fixedly connected to the second detection plate 31. The rubber hammer 37 is fixed in the fixing part 36 when not in use. The protruding detection rod 33 can be knocked by the rubber hammer 37 to make the detection rod 33 retract back into the positioning hole 32.

[0033] A support plate 51 is fixedly connected between the support legs 12. A support arm 52 is fixedly connected to the support plate 51. A bottom plate 53 is fixedly connected to the support arm 52. A plurality of electric telescopic rods 54 are fixedly connected to the bottom plate 53. A moving plate 55 corresponding to the detection groove 22 is arranged on the electric telescopic rod 54. The electric telescopic rod 54 can drive the moving plate 55 to move upward to eject the deviated instrument main body 24, and the problematic instrument main body 24 can be taken out of the detection groove 22 in the first time. The electric telescopic rod 54 is a prior art, and its specific structure and working principle will not be elaborated here. A rubber pad is arranged on the moving plate 55, and the rubber pad can play a buffering role to avoid damaging the instrument main body 24.

[0034] During use, refer Figures 1 - 4 As shown, by providing a detection groove 22 and a first fixing hole 23 at the same position as the installation position of the instrument main body 24 on the vehicle body, during detection, the instrument main body 24 is installed in the detection groove 22, and the second fixing hole 26 is located above the first fixing hole 23. By driving the detection rod 33 sliding in the positioning hole 32 downward by the second detection plate 31, when the second fixing hole 26 is aligned with the first fixing hole 23, the detection rod 33 can smoothly pass through the second fixing hole 26 and the first fixing hole 23.

[0035] When there is a deviation in the position of the second fixing hole 26, the detection rod 33 cannot pass through the second fixing hole 26 and will abut against the fixing ear 25. As the second detection plate 31 continues to move downward, the detection rod 33 abutting against the fixing ear 25 will protrude from the positioning hole 32. Until the second detection plate 31 moves onto the limit block 17 and cannot move any further, move the second detection plate 31 upward and observe the position of the detection rod 33. The detection rod 33 protruding from the positioning hole 32 indicates that the second fixing hole 26 located below it is deviated.

[0036] An automobile instrument assembly inspection tool, which can detect the fixing holes on the instrument and align with the fixing holes on the vehicle body during assembly.
