[0022] See also Figure 9-13 When this embodiment is used for motorcycle rack detection, its operation method is as follows: first, the middle parts of both sides of the load-bearing elbow N-1 of the motorcycle rack are respectively inserted into the two positioning grooves 4-1 of the two positioning seats 4 for positioning and symmetrical support; at the same time, the two outer ears N-3 are respectively located on the front and rear sides of the detection block 2-1, and the two inner ears N-4 are attached to the inclined block 3-1; then, the two first detection pins 2-2 are respectively passed through the first connecting holes N-31 on the two outer ears N-3 and then respectively inserted into the front and rear ends of the first detection hole 2-11; then, the two second detection pins 3-2 are respectively passed through the second connecting holes N-41 on the two inner ears N-4 and then respectively inserted into the two second detection holes 3-11; then, the two third detection pins 5-2 are pressed and respectively inserted into the third connecting holes N-51 of the two U-shaped arch plates N-5. If the two first detection pins 2-2, the two second detection pins 3-2 and the two third detection pins 5-2 can be inserted into place, it means that the product is qualified; otherwise, the product is judged to be unqualified (as long as any one of the detection pins cannot be inserted normally or cannot be inserted into place, it is considered unqualified). Therefore, the detection operation is simple, and the result judgment of whether it is qualified is also very simple.
[0023] In this embodiment, the two first detection pins 2-2 of the first detection assembly 2 can simultaneously detect the front-to-back symmetry and concentricity of the first connecting holes N-31 on the two outer ears N-3.
[0024] In this embodiment, the two second detection pins 3-2 of the second detection assembly 3 can simultaneously detect the front-to-back symmetry and parallelism of the second connecting holes N-41 on the two inner ears N-4.
[0025] In this embodiment, the third detection pins 5-2 of the two third detection components 5 can simultaneously detect the front-to-back symmetry and parallelism in the third connecting holes N-51 of the two U-shaped arch plates N-5.
[0026] In this embodiment, see Figure 6 The first detection pin 2-2 includes a first holding section 2-21, a first shoulder section 2-22 and a first detection section 2-23; the outer diameter of the first shoulder section 2-22 is larger than the outer diameter of the first detection section 2-23; the first detection section 2-23 is used to be inserted into the first detection hole 2-11.
[0027] Specifically, combined Figure 4-13 When the first detection pin 2-2 is used to detect the first connecting hole N-31 on the outer ear N-3, the first holding section 2-2 is held by hand, and then the first detection section 2-23 is inserted into one end of the first detection hole 2-11 after passing through the first connecting hole N-31 on the outer ear N-3. If the first shoulder section 2-22 can contact the outer ear N-3, it means that it has been inserted into place. At this time, the shape and position of the first connecting hole N-31 on the outer ear N-3 detected are qualified; otherwise, it is judged to be unqualified (such as unable to be inserted normally or cannot be inserted into place).
[0028] In this embodiment, see Figure 7 The second detection pin 3-2 includes a second holding section 3-21, a second shoulder section 3-22 and a second detection section 3-23; the outer diameter of the second shoulder section 3-22 is larger than the outer diameter of the second detection section 3-23; the second detection section 3-23 is used to be inserted into the second detection hole 3-11.
[0029] Specifically, see Figure 9-13When the second detection pin 3-2 is used for detecting the second connecting hole N-41 on the inner support ear N-4, the second holding section 3-21 is held by hand, and then the second detection section 3-23 is inserted into the second detection hole 3-11 after passing through the second connecting hole N-41 on the inner support ear N-4. If the second shoulder section 3-22 can contact the inner support ear N-4, it means that it has been inserted into place. At this time, the shape and position of the second connecting hole N-41 on the support ear N-4 detected are qualified; otherwise, it is judged to be unqualified (such as unable to be inserted normally or cannot be inserted into place).
[0030] In this embodiment, see Figure 8 The third detection pin 5-2 includes a third holding section 5-21, an orientation section 5-22, a third shoulder section 5-23 and a third detection section 5-24; the outer diameter of the third shoulder section 5-23 is larger than the outer diameter of the third detection section 5-24; the orientation section 5-22 is installed on the orientation hole 5-11 and can slide in a directional manner with a clearance fit.
[0031] Specifically, see Figure 9-13 When the third detection pin 5-2 is used to detect the third connecting hole N-51 on the U-shaped arch plate N-5, the third holding section 5-21 is held by hand, and then the orientation section 5-22 slides downward on the orientation hole 5-11 of the bracket 5-1, and the third detection section 5-24 is inserted downward into the third connecting hole N-511. If the third shoulder section 5-23 can contact the U-shaped arch plate N-5, it means that it has been inserted into place. At this time, the shape and position of the third connecting hole N-51 on the U-shaped arch plate N-5 detected are qualified; otherwise, it is judged to be unqualified (such as unable to be inserted normally or cannot be inserted into place).
[0032] When the inspection is completed, first pull out the two first inspection pins 2-2, the two second inspection pins 3-2 and the two third inspection pins 5-2, and then directly take the inspected motorcycle rack away from the inspection fixture, so the operation is very simple, saving time and effort.

[0034] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
