The second fixing component 40 is used to fix the second pipe 103 to cooperate with the bracket detection component 50 to detect the installation position of the guard plate 104 and the bracket 105 of the muffler 10.

[0042] Combined with Figure 1 and attached Figure 3 The first fixing component 20 includes at least one support member 21 and an adjusting member 22. The adjusting member 22 is detachably mounted on the support member 21. The two adjusting members 22 are spaced apart on the support member 21 along the front-to-back direction. The spacing dimensions of the two adjusting members 22 in the front-to-back direction are configured to be adjustable relative to the support member 21 to match the dimensions of the shell 101 in the front-to-back direction.

[0043] In an optional solution, the adjusting member 22 can be used to detect whether the size of the shell 101 in the front-to-back direction meets the requirements. The spacing size between the two adjusting members 22 can be set according to the size of the shell 101 in the front-to-back direction that meets the requirements. If the shell 101 cannot be placed between the two adjusting members 22, the size of the shell 101 in the front-to-back direction does not meet the requirements.

[0046] Exemplarily, the adjusting member 22 is configured as a cylindrical member, and of course, it can also be configured as a prismatic member, etc. Those skilled in the art can set the shape specifications of the adjusting member 22 according to actual needs.

[0047] Exemplarily, the first adjustment hole 211 is set as a screw hole, and the outer wall of the adjustment member 22 close to the support member 21 is provided with a thread, and the adjustment member 22 is screwed into the first adjustment hole 211 by screwing to achieve detachable installation of the adjustment member 22.

[0048] Exemplarily, the adjusting member 22 is interference fit with the first adjusting hole 211 , and the side of the adjusting member 22 close to the supporting member 21 is interference installed in the first adjusting hole 211 , which is convenient for assembly and disassembly.

[0049] In one embodiment, as shown in the attached Figure 3 As shown, the first fixing component 20 also includes a positioning member 23 located on one side of the support member 21 and connected to the support member 21. The positioning member 23 is used to cooperate with the left end or the right end of the shell 101 to enable the shell 101 to be quickly positioned. The positioning member 23 includes a base 231 and a side block 232. The base 231 extends in the left and right directions, and one end of the base 231 is detachably connected to the support member 21. The side block 232 is located at one end of the base 231 away from the support member 21 and is connected to the base 231.

[0050] In an optional solution, a plurality of second adjustment holes 212 are provided on the support member 21, and the plurality of second adjustment holes 212 are distributed on the support member 21 along the front-to-back direction, and the second adjustment holes 212 are provided along the left-to-right direction and penetrate the support member 21, and a connecting hole is provided at one end of the base 231 close to the support member 21, and the connecting hole can cooperate and connect with the second adjustment holes 212, and the number of the second adjustment holes 212 is greater than the number of the connecting holes.

The setting of the functional groove 213 allows a gap to be left between the lower end of the shell 101 and the upper surface of the support member 21 through the functional groove 213, thereby reducing the contact area between the shell 101 and the support member 21, making it easy to separate the shell 101 from the first fixing component 20 and to remove the muffler 10. A pin can be used to extend into the functional groove 213 along the left and right directions to lift the shell 101 upward to remove the muffler 10.

[0053] In one embodiment, in combination with Figure 4 and attached Figure 5 The automobile muffler detection tooling proposed in the utility model also includes a pipe diameter detection component 30, which is used to detect the pipe diameter of the first pipe fitting 102. The pipe diameter detection component 30 includes a first support 31 and a pipe diameter detection member 32. The pipe diameter detection member 32 can be movably installed on the first support 31.

The set outer diameter of the first pipe 102 is defined as the outer diameter size of a qualified first pipe 102, or the maximum size of the outer diameter of a qualified first pipe 102 that can be allowed within the error range. The sleeve 322 detects the outer diameter of the first pipe 102 through the detection hole 323. By sleeve-mounting the sleeve 322 on the first pipe 102, the detection hole 232 is matched with the first pipe 102 to determine whether the outer diameter of the first pipe 102 meets the requirement. If the sleeve 322 cannot be sleeved on the first pipe 102, the outer diameter of the first pipe 102 does not meet the requirement.

[0055] In one alternative, if Figure 5As shown, a protrusion 324 coaxially connected to the socket 322 is provided in the detection hole 323, and the outer diameter size of the protrusion 324 is set to the set inner diameter of the first pipe fitting 102 of the muffler 10. The set inner diameter of the first pipe fitting 102 is defined as the inner diameter size of the qualified first pipe fitting 102. When the socket 322 is sleeved on the first pipe fitting 102, the protrusion 324 is used to penetrate into the first pipe fitting 102. Through the setting of the protrusion 324, it is possible to detect whether the inner diameter size of the first pipe fitting 102 meets the requirements. The protrusion 324 cooperates with the socket 322 to realize the detection of the inner and outer diameters of the first pipe fitting 102.
