[0029] like Figure 1-3 As shown, this utility model provides a tool for easily inspecting car bumpers, which has a tool table 1. A suction cup 4 for supporting the middle of the bumper is vertically slidably connected on the middle of the tool table 1. Two horizontally slidably connected movable plates 20 are provided on the tool table 1 and on both sides of the suction cup 4. Each movable plate 20 is provided with a side support component 2 and a pressing component 3 for supporting the two sides of the bumper.

[0030] Optionally, in the above technical solution, a through hole A11 is provided in the middle of the inspection table 1, a nut 41 is fixedly installed in the through hole A11, a lead screw 42 is threaded into the nut 41, and a suction cup 4 is rotatably connected to the top of the lead screw 42.

[0031] Optionally, in the above technical solution, the inspection table 1 is also provided with a through hole B12 located on one side of the through hole A11. A guide rod 44 is slidably connected in the through hole B12. The top end of the guide rod 44 is fixedly connected to the suction cup 4. A handle 43 is fixedly installed on the bottom wall of the lead screw 42.

[0032] Optionally, in the above technical solution, the side support component 2 includes a rotating plate 21 and a lower curved surface template 22. The rotating plate 21 is rotatably connected to the moving plate 20, and a plurality of support rods 23 for supporting the lower curved surface template 22 are fixedly installed on the rotating plate 21 at equal intervals.

[0033] Optionally, in the above technical solution, the bottom end of the base rod 24 is fixedly installed on the movable plate 20, the top end of the base rod 24 is hinged to the rotating plate 21, and the fixed end of the telescopic cylinder A25 is also hinged to the movable plate 20, and the movable end of the telescopic cylinder A25 is hinged to the rotating plate 21.

[0034] Optionally, in the above technical solution, the pressing component 3 includes a telescopic cylinder 31 fixedly installed on the movable plate 20. The movable end of the telescopic cylinder 31 extends upward and is fixedly installed at one end of a connecting plate 32. The other end of the connecting plate 32 extends above the side support component 2 and is fixedly installed at the end of a hinge seat A33. A hinge seat B34 is hinged to the hinge seat A33, and an upper curved template 35 is fixedly installed on the bottom wall of the hinge seat B34.

[0035] Furthermore, the inspection table 1 has two symmetrical and horizontally arranged slide grooves 13. A slider 14 driven by a cylinder is slidably connected in the slide groove 13. The slider 14 is fixedly connected to the middle of the bottom wall of the moving plate 20 on the same side. The cylinders in the two slide grooves 13 are symmetrically arranged and fixedly installed in the slide grooves 13. The moving end of the cylinder is fixedly connected to the slider 14. This arrangement is used to drive the moving plate 20 to slide.

[0036] In this application, the support rod 23 can be replaced with a telescopic cylinder structure, with the aim of adjusting the curvature of the lower curved template 22.

[0037] The lead screw 42 and guide rod 44 are at the same height, and the height of the lead screw 42 is less than the height from the top to the bottom of the fixture table 1, so that the suction cup 4 can move down to the position of fitting the fixture table 1.

[0038] Working principle:

[0039] In use, the distance between the two side support components 2 is adjusted by moving the plate 20 according to the length of the bumper to be inspected. The height of the suction cup 4 relative to the lower curved template 22 is adjusted according to the arc height. The angle of the lower curved template 22 is adjusted according to the arc. Then, the bumper is placed on the inspection fixture in a "high on both sides and low in the middle" shape. First, the middle of the bumper is placed on the suction cup 4, and the two sides are in contact with the lower curved template 22 (the bumper only needs to partially contact the lower curved template 22 for stable placement). Then, the upper curved template 35 is moved down to position the bumper. At this time, the inspection fixture fits the bumper and can clamp the two sides of the bumper, so the bumper can be inspected.

[0040] The height adjustment method of suction cup 4 is as follows: while rotating handle 43 to drive lead screw 42 to rotate, lead screw 42 moves up or down under the action of threaded connection, which drives the rotating suction cup 4 to move in the same direction. The suction cup 4 moves vertically in the left and right directions of guide rod 44, that is, it will not rotate.

[0041] The angle adjustment method of the lower curved template 22 is as follows: start the telescopic cylinder A25 to extend its movable end (in the initial state, the movable end of the telescopic cylinder A25 extends half of its total length, at which time the rotating plate 21 is in a horizontal state). Under the action of the hinge, the rotating plate 21 rotates clockwise or counterclockwise relative to the end connected to the bottom rod 24, adjusting the angle of the lower curved template 22 so that the lower curved template 22 fits the bumper better.

[0042] The working method of the pressing component 3 is as follows: the pressing component 3 moves simultaneously with the side support component 2 on the moving plate 20. The suction cup 4 is always below the lower curved template 22. After the curvature of the lower curved template 22 is adjusted, the telescopic cylinder 31 is activated to retract its movable end (in the initial state, the movable end of the telescopic cylinder 31 is fully extended). The connecting plate 32 drives the hinge seat A33 to move down. Under the action of the hinge, the upper curved template 35 bottom wall abuts against the bumper, thus completing the clamping of the bumper.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
