The head tube tightening cylinder 31 is connected to the cylinder positioning plate 32 and is used to clamp and fix the upper port of the head tube of the vehicle frame 7.

[0026] As Figure 3 shown, the slide rail mechanism 4 is arranged between the bottom plate 1 and the head tube bottom plate 36, and includes an X-direction slide rail 41, a Y-direction slide rail 42, an X-direction slider 43, a Y-direction slider 44, a slide rail mounting plate 45, and a slide rail platform 6. As Figure 4 shown, the slide rail platform 6 among them includes a slide rail platform end plate 61, a slide rail platform vertical plate 62, and a slide rail platform bottom plate 63 connected in sequence from top to bottom. The slide rail platform bottom plate 63 is connected to the bottom plate 1. As Figure 3As shown in the figure, two X-direction slide rails 41 are arranged on the top of the slide rail platform end plate 61 parallel to the direction of the vehicle frame 7. The bottom of the slide rail mounting plate 45 is slidably connected to the X-direction slide rail 41 through an X-direction slider 43. The Y-direction slide rail 42 is arranged on the top of the slide rail mounting plate 45 perpendicular to the direction of the vehicle frame 7. The bottom of the head tube bottom plate 36 is slidably connected to the Y-direction slide rail 42 through a Y-direction slider 44.

[0027] The scale mechanism 5 includes an X-direction scale 51 and an X-direction pointer 52 arranged parallel to the X-direction slide rail 41, and a Y-direction scale 53 and a Y-direction pointer 54 arranged parallel to the Y-direction slide rail 42. The X-direction scale 51 is fixedly connected to the top of the slide rail platform end plate 61. The X-direction pointer 52 is fixedly connected to the side of the slide rail mounting plate 45. When the X-direction slider 43 moves along the X-direction slide rail 41, the X-direction pointer 52 points to different scales on the X-direction scale 51. The Y-direction scale 53 is fixedly connected to the top of the slide rail mounting plate 45. The Y-direction pointer 54 is fixedly connected to the lower edge of the head tube bottom plate 36. When the Y-direction slider 44 moves along the Y-direction slide rail 42, the Y-direction pointer 54 points to different scales on the Y-direction scale 53.

[0028] A slide rail locking guide post 8 is movably connected between the head tube bottom plate 36, the slide rail mounting plate 45, and the slide rail platform end plate 61. X-direction protective blocks 64 are connected to the front and rear sides of the slide rail platform end plate 61. Y-direction protective blocks 46 are connected to the left and right sides of the slide rail mounting plate 45.

[0029] Preferably, as Figure 1 shown in the figure, the flat fork fixing mechanism 2 includes left and right pushing cylinders 21 symmetrically arranged on both sides of the vehicle frame 7. The left and right pushing cylinders 21 are connected to the bottom plate 1 through a mounting frame 22. A plurality of reference blocks 10 are arranged on the bottom plate 1.

[0030] As Figure 4 shown in the figure, a flat fork shaft point backward propulsion positioning mechanism 9 is further arranged on the bottom plate 1, including a backward pushing cylinder 91 and a pushing block 92. The backward pushing cylinder 91 is fixedly connected to the bottom plate 1. The pushing block 92 is slidably connected to the bottom plate 1 and is connected to the output shaft of the backward pushing cylinder 91.

[0031] The working process of the above embodiment is as follows:

[0032] First, position according to the reference blocks 10 on the bottom plate 1, place the vehicle frame 7 stably in the corresponding position of the inspection tool, pull out the slide rail locking guide post 8 upward, start the backward pushing cylinder 91, the left and right pushing cylinders 21, and the head tube pushing cylinder 31, and clamp the vehicle frame 7 from the rear end, the flat fork mounting point, and the upper port of the head tube of the vehicle frame 7 respectively.

[0033] Then, perform numerical reading, as Figure 5As shown, taking the X direction as an example, the scale mechanism consists of an X-direction scale 51 and an X-direction pointer 52. If the X-direction pointer 52 points to the center line mark of the X-direction scale 51, it indicates that there is no dimensional deviation in the front-back direction of the fabricated frame 7. If the Y-direction pointer 54 points to the center line mark of the Y-direction scale 53, it indicates that there is no dimensional deviation in the left-right direction of the fabricated frame 7.

[0034] When reading the X-direction scale 51, if the X-direction pointer 52 deflects to the left, it indicates that the head tube is offset forward from the standard position, and the reading is the forward offset dimension; if the X-direction pointer 52 deflects to the right, it indicates that the head tube is offset backward from the standard position, and the reading is the backward offset dimension. Generally, it is required that the offset dimensions do not exceed 3 mm each.

[0035] When reading the Y-direction scale 53, if the Y-direction pointer 54 deflects to the left, it indicates that the head tube is offset to the left from the standard position, that is, the symmetry of the frame 7 is abnormal, and the reading is the left offset dimension; if the Y-direction pointer 54 deflects to the right, it indicates that the head tube is offset to the right from the standard position, and it also indicates that the symmetry of the frame 7 is abnormal, and the reading is the right offset dimension. Generally, it is required that the offset dimensions do not exceed 2 mm each.

[0036] The X-direction protective block 64 and the Y-direction protective block 46 are used for the limiting function during the movement of the slide rail mechanism 4, respectively limiting the front and back of the slide rail mounting plate 45 and the left and right of the head tube bottom plate 36.

[0037] The above specific implementation manners are only for explaining the technical concept and structural features of the present invention, aiming to enable those skilled in the art to implement it accordingly. However, the above content does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention shall fall within the protection scope of the present invention.
