A hydraulic cylinder 4 is fixedly connected to the top of the device body 1. A telescopic shaft 3 extending into the device body 1 is connected to the output end of the hydraulic cylinder 4. A housing 5 is detachably connected to the movable end of the telescopic shaft 3. A threaded groove 21 is fixedly connected to the top of the housing 5. A rotatable threaded connector 20 is connected to the movable end of the telescopic shaft 3, and the threaded connector 20 is threadedly connected to the threaded groove 21. A first mounting block 22 is fitted onto the surface of the threaded groove 21, and the first mounting block 22 is connected to the threaded groove 21 by screws. The bottom end of the housing 5 is open. The device has a groove 28, and a tester 24 is detachably connected inside the groove 28. Multiple electrical terminals 27 are fixedly connected to the top of the tester 24. A power receiving groove 29 corresponding to the electrical terminals 27 is fixedly connected to the top wall of the groove 28, and the electrical terminals 27 and the power receiving groove 29 are engaged. A power wire 23 is provided at the top of the outer shell 5, and the two ends of the power wire 23 are respectively connected to the power supply equipment and the power receiving groove 29. Multiple test plugs 6 are detachably connected to the bottom of the tester 24. Electric slide rails 9 are symmetrically embedded in the device body 1. A test platform 7 is slidably connected to the electric slide rails 9 through a first slider 10.

[0027] The bottom of the tester 24 is provided with multiple second slots 30 corresponding to the test plug 6, and the test plug 6 engages with the second slots 30 and is fixed to the bottom of the tester 24 by screws and the second mounting block 31. The controller of the control cylinder 4, servo motor 12, electric guide rail and electric push rod 19 is fixedly connected to the main body 1 of the device.

[0028] Working principle: Before testing the body controller, select a suitable tester 24 according to the size of the batch of body controllers, insert it into the groove 28, and then fix it with screws. At this time, the power terminal 27 on the top of the tester 24 is engaged with the power slot 29 in the groove 28, and power is supplied through the power wire 23. Then, the outer shell 5 is threaded to the threaded connector 20 through the threaded groove 21, and the first mounting block 22 is fixed to the cross section of the threaded groove 21 with screws, thereby strengthening the tester 24. Finally, according to the test hole model on the body controller, select a matching test plug 6 and insert it into the second slot 30. Then, fix it to the tester 24 with screws and the second mounting block 31. At this time, the controller can start the cylinder 4 to drive the telescopic shaft 3 to move the outer shell 5, and insert the test plug 6 into the body controller for testing.

[0029] The tester 24 adopts existing technology, and a suitable tester 24 from the existing technology shall be selected and installed by a person skilled in the art, such as SG-CDD13 (TC-6001).

[0030] This invention, by setting up a detachable and replaceable tester 24 and test plug 6, allows for the selection of a suitable tester 24 and test plug 6 based on the vehicle body control to be tested, and enables testing of the vehicle body control. Furthermore, the test plug 6 can be automatically connected to the vehicle body controller via the hydraulic cylinder 4 and the telescopic shaft 3, reducing labor and improving testing efficiency.

[0031] Second implementation method:

[0032] Figures 1-2 and Figures 6-7 The device body 1 has symmetrically embedded threaded sleeves 16 on its inner wall. A lead screw 13 is movably connected inside the detection plug 6, and two lead screws 13 are detachably connected to a clamping plate 8 at one end near each other. A bracket is fixedly connected to the side of the device body 1, and a servo motor 12 is fixedly connected to the bracket. The output end of the servo motor 12 is connected to one of the lead screws 13. A first slot 26 is fixedly connected to the end of the clamping plate 8 near the lead screw 13. Limiting holes are symmetrically formed on the surfaces of the first slot 26 and the lead screw 13. After the lead screw 13 engages with the first slot 26, the first slot 26 passes through the limiting holes and is fixed by bolts 25. The device body 1 is symmetrically rotated below the electric slide rail 9. There is a rotating shaft 17 extending outside the device body 1. Two rotating shafts 17 are fitted with gears on their surfaces close to each other, and the two gears are meshed together. A set of belt pulleys 15 are fitted on the surfaces of the rotating shafts 17 and the corresponding threaded sleeves 16, and each set of belt pulleys 15 is connected to each other by a belt 14. An electric push rod 19 is embedded in the back of the device body 1. The movable end of the electric push rod 19 is connected to a side plate 18. An inner compartment is opened at the side end of the device body 1 below the rotating shafts 17. A storage box 11 is provided in the inner compartment. Electric guide rails are symmetrically fixedly connected to the side end of the device body 1 near the storage box 11. A transparent protective door 2 is slidably connected to the electric guide rails through a second slider.

[0033] Working principle: After placing the vehicle body controller to be tested on the test platform 7, the controller activates the first slider 10 to drive the test platform 7 to move directly below the tester 24. At this time, the servo motor 12 can be activated to drive one of the lead screws 13, and through the belt 14 and belt pulley 15, the rotating shaft 17 is driven to rotate synchronously. Then, through two gears, the two rotating shafts 17 are driven to rotate in opposite directions, thereby indirectly driving the lead screws 13 on both sides to rotate synchronously in opposite directions. The adjustable clamp 8 can clamp and position the vehicle body controller to prevent displacement during the test. Then, the electric push rod 19 is activated to drive the side plate 18 to fix the vehicle body controller in place. The storage box 11 contains multiple replacement clamps 8. If the clamps are damaged after long-term use, the bolts 25 can be loosened to disassemble the first slot 26 from the lead screw 13, so that the clamps 8 can be replaced. When the device body 1 is not in use, the protective door 2 can be opened by opening the electric guide rail to seal the inside of the device body 1, which has a protective function.

[0034] This utility model, by setting adjustable clamping plate 8 and side plate 18, can perform positioning tests on different models of vehicle body controllers.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
