The top of the adjustment slider is connected to the bottom of the detection support through a connecting column. A fixed rack is fixed on the side wall of the adjustment groove, and rack blocks that can be controlled to extend or retract are slidably installed on the two corresponding side walls of the adjustment slider. When the rack blocks are in the extended state, they cooperate with the fixed rack.

[0008] A further technical improvement of this utility model is that: a rotating disk is fixed coaxially with the connecting column inside the adjusting slider, an involute groove is opened on the rotating disk, a roller is rolled in the involute groove, and the roller is connected to the rack and pinion block through a connecting rod.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figure 1-6 As shown, an automatic inspection tool for a front suspension support of an automobile includes an electrical control box 1 and a mounting plate 2 fixed on its top. A central positioning pin 4 is fixedly installed at the middle position of the top of the mounting plate 2. Three fan-shaped grooves 201 are evenly opened around the central positioning pin 4 on the top of the mounting plate 2. An angle adjustment block 5 is slidably installed in each fan-shaped groove 201. A detection support 6 is slidably installed on the top of each angle adjustment block 5 along the radial direction.

[0026] Each detection support 6 has a detection port at its top, and a distance sensor 12 is fixedly installed at the bottom of the detection port;

[0027] Each angle adjustment block 5 is provided with an adjustment groove 502 that provides a sliding path for the detection support 6. An adjustment slider 14 is slidably arranged in the adjustment groove 502. A connecting column 15 is rotatably connected to the top of the adjustment slider 14, and the top of the connecting column 15 is fixed to the bottom of the detection support 6.

[0028] Furthermore, the mounting plate 2 has an angle scale on the inner side of the fan-shaped groove 201, and the top inner side of the angle adjustment block 5 has an indicator mark scale; the angle adjustment block 5 has a transmission cavity 501, and a bevel gear 9 and a bevel gear 10 are rotatably arranged in the transmission cavity 501. The top of the bevel gear 9 is coaxially fixed with a stop adjustment bolt 8, and a section of external thread is coaxially arranged on one side of the bevel gear 10. A stop screw sleeve 11 is sleeved on the outer side of the external thread, and the stop screw sleeve 11 and the external thread are threadedly driven; when the stop adjustment bolt 8 is turned by a wrench, the stop screw sleeve 11 can be driven to translate through gear transmission and thread transmission. After translating outward, it can make contact and squeeze with the groove wall of the fan-shaped groove 201, thereby fixing the position of the angle adjustment block 5.

[0029] Furthermore, a fixed rack 13 is fixed to the middle side wall of the adjusting slide 502, and a rack block 16 is slidably installed at the middle position of the corresponding side wall of the adjusting slider 14. A rotating disk 17 is rotatably installed in the central cavity of the adjusting slider 14, and the rotating disk 17 is coaxially fixed with the connecting column 15. A progressive groove 1701 is symmetrically opened on the center of the rotating disk 17, and a roller 19 is rolled in the progressive groove 1701. A connecting rod 18 is provided between each roller 19 and the corresponding rack block 16. The roller 19 and the connecting rod 18 are rotatably connected, and the other end of the connecting rod 18 is fixedly connected to the rack block 16.

[0030] It should be noted that the bottom connecting wire of the distance sensor 12 is electrically connected to the electrical control box 1 through the connecting post 15, the adjusting slider 14 and the clearance through hole on the rotating disk 17; two handles 7 are also symmetrically installed on the top of the mounting plate 2; the outer diameter of the connecting screw at the triangular position of the component to be tested 3 is clearance-fitted with the inner diameter of the detection port.

[0031] When using this utility model, turn on the power, put the component to be tested 3 on the center positioning pin 4, and let the connecting screw at the triangular position enter the detection port. The distance sensor 12 detects the depth of the connecting screw entering the detection port, thereby determining whether its protrusion length is qualified.

[0032] The distance sensor 12 transmits the signal to the microcontroller in the control box 1 for processing, calculates its extension length, and compares the extension length with a set threshold. If it is qualified, the green light installed on the outside of the control box will light up; if it is not qualified, the red light will light up; if no component is detected, the yellow light will light up.

[0033] Since the parts to be inspected 3 may be different for different vehicle models, it is necessary to adjust the positions of the three inspection supports 6. After the angle adjustment block 5 supporting the inspection support 6 is adjusted in the sector groove 201, the stop adjustment bolt 8 is rotated to make the stop screw sleeve 11 move to contact and squeeze the groove wall of the sector groove 201, thus completing the limit fixation. After the relative position of the inspection support 6 and the angle adjustment block 5 is adjusted, the inspection support 6 is rotated, thereby driving the rotating disk 17 to rotate through the connecting column 15. The involute groove 1701 on the rotating disk 17 squeezes the roller 19, thereby driving the rack and pinion block 16 to move outward until it cooperates with the fixed rack 13, thus completing the positioning of the inspection support 6.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
