DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0017] A vehicle frame inspection tool for placing a tricycle frame, in combination with Figure 1 as shown, includes a go - no - go gauge 1, a head tube detection plate 2, a tricycle frame 3, a fixed fixture 4, a left - right deviation detection plate 5, a detection table 6, a support table 7, and a detection rod 8. The fixed fixture 4 includes a movable seat 41, a clamping seat 42, a pressing block 43, and an adjusting rod 44; the left - right deviation detection plate 5 includes a base 51, a vertical plate 52, and a reinforcing plate 53.

[0018] The inspection table 6 is horizontally arranged, and through holes are evenly arranged on the inspection table 6 to facilitate the installation and fixation of components on the inspection tool.

[0019] At the center of the left end of the upper end surface of the inspection table 6, a support table 7 is arranged. On the support table 7, a head tube inspection plate 2 is arranged along the placement direction of the vehicle frame. The head tube inspection plate 2 is vertically arranged, and a go-no-go gauge 1 for detecting the distance between the head tube and the head tube inspection plate is arranged on the head tube inspection plate 2.

[0020] On the right side of the inspection table 6, two juxtaposed clamping mechanisms are arranged, and the two clamping mechanisms are respectively located at the left part and the middle part of the inspection table 6. The clamping mechanism includes a detection rod 8 longitudinally arranged on the inspection table 6, and the extending direction of the detection rod 8 is perpendicular to the extending direction of the vehicle frame. A number of uniformly arranged fixing holes are arranged on the detection rod 8, and a pair of symmetrically arranged fixing jigs 4 are movably arranged on the detection rod 8. The vehicle frame is clamped by the fixing jigs in the two clamping mechanisms.

[0021] The fixing jig 4 includes a moving seat 41 in an L shape for placing the vehicle frame. The moving seat 41 is connected to the upper end surface of the detection rod 8 by bolts. On the outer side of the upper end surface of the moving seat 41, a clamping seat 42 is arranged. The fixation of the position of the clamping seat 42 can realize the fixation of the outer side of the vehicle frame. A pressing block 43 for pressing the vehicle frame from above is arranged on the clamping seat 42. The pressing block 43 is connected with an adjusting rod 44 for adjusting the height of the pressing block 43. A thread is arranged in the middle of the adjusting rod 44. The adjusting rod 44 is screwed on the clamping seat 42 through the thread. By rotating the adjusting rod, the height of the pressing block can be adjusted to realize the pressing or loosening of the vehicle frame.

[0022] On the right part of the inspection table 6, three pairs of relatively arranged left-right deviation inspection plates 5 are arranged, and the three pairs of left-right deviation inspection plates 5 are evenly arranged on the right part of the inspection table 6.

[0023] The left-right deviation inspection plate 5 is in an L shape and includes a base 51 arranged horizontally. Bolt holes for positioning are arranged on the base 51 for connecting the base to the inspection table. A vertical plate 52 is connected to the base 51, and a reinforcing plate 53 for increasing stability is connected between the vertical plate 52 and the base 51.

[0024] When the utility model is actually used, the tricycle frame to be detected is placed on the inspection table, and the positions of the left-right deviation inspection plates are fixed according to the standard size of the vehicle frame. The pressing block is controlled to press the vehicle frame through the adjusting rod, and the fixing jig clamps and fixes the vehicle frame. Then, the left-right deviation amount (error range 1-2 mm) of the head tube of the vehicle frame is detected by the go-no-go gauge; the distance between the vehicle frame and the left-right deviation inspection plates is measured by a scale (error range 1-3 mm). If the detection result exceeds the error range, it is determined as unqualified, and the welding tooling of the vehicle frame needs to be adjusted.
