Technical Field
[0001] This utility model relates to the field of inspection tools, and in particular to an inspection tool for the position of an automotive exhaust treatment valve body. Background Technology
[0002] The automotive exhaust treatment valve body 21 is tubular, such as Figure 2 , Figure 5 As shown, the automotive exhaust treatment valve body 21 requires machining holes and pillars 23. The valve body 21 has two radially protruding strips 22, and the opposite end faces of these strips are machined with pillars 23 and first holes 24. The circumference of the valve body 21 has two second holes 19 and one third hole 20. A ring of connecting holes 26 is also machined around the bottom of the valve body 21. After machining, the positions of the holes and pillars 23 on the valve body need to be inspected to check the machining accuracy of the automotive exhaust treatment valve body 21. However, currently there is no inspection tool for machining the pillars 23 and various holes of the automotive exhaust treatment valve body 21. Therefore, there is an urgent need to design an inspection tool for inspecting the pillars 23 and various holes of the automotive exhaust treatment valve body 21. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a position gauge for automotive exhaust treatment valve bodies that improves the efficiency of operators' inspections and ensures the accuracy of inspections.
[0004] To achieve the above objectives, one of the technical solutions adopted by this utility model is: a position gauge for an automotive exhaust gas treatment valve body, comprising:
[0005] Base plate;
[0006] A circular limiting seat is provided on the base plate, which is used to support the bottom of the automobile exhaust treatment valve body;
[0007] The base plate is provided with a plurality of bottom gauge seats with holes. The plurality of bottom gauge seats are distributed along the circumference of the circular limiting seat and correspond one-to-one with a ring of connecting holes at the bottom of the automobile exhaust treatment valve body. A connecting hole detection tool can be vertically inserted into each bottom gauge seat.
[0008] A pressure plate is provided on the base plate, and the pressure plate is driven by a quick clamp to press against the top of the vehicle exhaust treatment valve body;
[0009] The base plate is provided with two protrusion detection seats, and each of the protrusion detection seats is horizontally inserted with two column detection tools for detecting the column and two first hole detection tools for detecting the first hole;
[0010] The base plate is provided with two first detection seats, and a second hole detection tool is horizontally inserted into each of the first detection seats;
[0011] A second detection seat is provided on the base plate, and a third hole detection tool is horizontally inserted on the second detection seat.
[0012] The beneficial effects of this utility model's automotive exhaust treatment valve body position gauge are as follows: The bottom of the automotive exhaust treatment valve body is limited by a circular limiting seat, and then a quick clamp drives a pressure plate to rotate, pressing the top of the automotive exhaust treatment valve body and limiting it on the circular limiting seat. After the automotive exhaust treatment valve body is fixed, various testing tools are manually moved to perform position measurement. These testing tools include a connection hole testing tool, two cylindrical testing tools, two first hole testing tools, a second hole testing tool, and a third hole testing tool. There is no necessary order in which these tools are inserted. Adopting this technical solution improves the operator's testing efficiency and ensures testing accuracy.
[0013] Preferably, both the column detection tool and the first hole detection tool are cylindrical in shape, with a column limiting plane and a first limiting plane respectively provided on their sides. Each of the protruding detection seats is provided with four protruding bolts, each located on one side of its corresponding column limiting plane or first limiting plane. When the column detection tool and the first hole detection tool move outward, the column limiting plane and the first limiting plane are respectively limited by their corresponding protruding bolts. By cooperating with the column limiting plane, the outward movement of the column detection tool is limited, preventing it from detaching from the fixture; by cooperating with the first limiting plane, the outward movement of the first hole detection tool is limited, preventing it from detaching from the protruding detection seat, thus solving the problem of fixture loss.
[0014] Preferably, the second hole detection tool is cylindrical, and its outer surface is provided with a limiting flange. When the second hole detection tool moves outward, it is limited by the limiting flange on the first detection seat. The limiting flange is provided to limit the outward movement of the second hole detection tool, preventing it from detaching from the first detection seat and solving the problem of easy loss of the inspection tool.
[0015] Preferably, the third hole detection tool has a cylindrical structure, and a third limiting plane is provided on the side of the third hole detection tool. A detection limiting bolt is provided on the second detection seat. When the third hole detection tool moves outward, the third limiting plane of the third hole detection tool is limited by the detection limiting bolt. Similarly, the cooperation between the third limiting plane and the detection limiting bolt is used to limit the outward movement of the third hole detection tool, preventing it from detaching from the second detection seat and solving the problem of easy loss of the inspection tool.
[0016] Preferably, the connecting hole detection tool has a cylindrical structure, and a connecting hole limiting plane is provided on the side of the connecting hole detection tool. A connecting hole limiting bolt is provided on the bottom fixture seat. The connecting hole limiting bolt corresponds to the connecting hole limiting plane. When the connecting hole detection tool moves downward, the connecting hole limiting plane of the connecting hole detection tool is limited by the connecting hole limiting bolt. Similarly, by the cooperation of the connecting hole limiting plane and the connecting hole limiting bolt, the downward movement of multiple connecting hole detection tools below is limited, so that the connecting hole detection tools do not detach from the bottom fixture seat, thus solving the problem of easy loss of fixtures.
[0017] Preferably, the bottom of the base plate is provided with multiple support columns, which are located at the four right angles of the base plate. The base plate is suspended in the air, which facilitates the operator to check the position of the connection holes at the bottom.
[0018] Preferably, a positioning post is provided on the base plate, the positioning post corresponds to one of the connection holes at the bottom of the vehicle exhaust treatment valve body, and the total number of the positioning post and the bottom inspection seat is the same as the number of connection holes.

The quick clamp 6 is driven and can press against the top of the vehicle exhaust treatment valve body 21; the base plate 1 is provided with two protrusion detection seats 7, and each protrusion detection seat 7 is horizontally inserted with two column detection tools 8 for detecting column 23 and two first hole detection tools 9 for detecting first hole 24; the base plate 1 is provided with two first detection seats 10, and each first detection seat 10 is horizontally inserted with a second hole detection tool 11; the base plate 1 is provided with a second detection seat 12, and the second detection seat 12 is horizontally inserted with a third hole detection tool 13.

Each convex bolt is located on one side of the column limiting plane 14 or the first limiting plane 15 corresponding to it. When the column detection tool 8 and the first hole detection tool 9 move outward, the column limiting plane 14 and the first limiting plane 15 are respectively limited by the convex bolts corresponding to them.
[0028] The second hole detection tool 11 is cylindrical, and a limiting flange 16 is provided on its outer surface. When the second hole detection tool 11 moves outward, the second hole detection tool 11 is limited on the first detection seat 10 by the limiting flange 16.
[0029] The third hole detection tool 13 has a cylindrical structure. A third limiting plane 17 is provided on the side of the third hole detection tool 13. A detection limiting bolt is provided on the second detection seat 12.

[0030] The connecting hole inspection tool 4 has a cylindrical structure. A connecting hole limiting plane 18 is provided on the side of the tool, and a connecting hole limiting bolt is provided on the bottom fixture base 3. The connecting hole limiting bolt corresponds to the connecting hole limiting plane. When the connecting hole inspection tool 4 moves downward, the connecting hole limiting plane 18 is limited by the connecting hole limiting bolt. Similarly, the cooperation between the connecting hole limiting plane 18 and the connecting hole limiting bolt limits the downward movement of the multiple connecting hole inspection tools 4 below, preventing the connecting hole inspection tools 4 from detaching from the bottom fixture base 3.
[0031] Multiple support columns 20 are provided at the bottom of the base plate 1, and the support columns 20 are located at the four right angles of the base plate 1. The base plate 1 is suspended, which makes it convenient for operators to check the position of the connection holes 26 at the bottom.

In this embodiment, the outward movement of the column inspection tool 8 is limited by the cooperation between the convex bolt and the column limiting plane 14. The outward movement of the first hole inspection tool 9 is limited by the cooperation between the convex bolt and the first limiting plane 15. The outward movement of the second hole inspection tool 11 is limited by the setting of the limiting flange 16, so that it does not detach from the first inspection seat 10. The outward movement of the third hole inspection tool 13 is limited by the cooperation between the third limiting plane 17 and the inspection limiting bolt, so that it does not detach from the second inspection seat 12. In the end, all inspection tools do not detach from the fixture, thus solving the problem of inspection tool loss.
