[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] As Figures 1-7 shown, the present application relates to a go-no-go gauge inspection tool for structural parts. The go-no-go gauge inspection tool for structural parts includes: a base 1, a first inspection block 2 disposed on one side of the top of the base 1; a second inspection block 3 disposed on the other side of the top of the base 1; the first inspection block 2 has a first inspection area 21 for inspecting the first feature of the structural part 4, and is used to inspect the first feature of the structural part 4.

[0034] When the first inspection block 2 inspects that the first feature of the structural part 4 is qualified, the second inspection block 3 is used to inspect the second feature of the structural part 4. When the inspected first feature is unqualified, the inspection of the second inspection block 3 is no longer carried out; the second inspection block 3 has a second inspection area 31 for inspecting the second feature of the structural part 4, and is used to inspect the second feature of the structural part 4. When the first feature is inspected to be qualified and the second feature is inspected to be qualified, the structural part 4 is qualified; when the first feature is inspected to be qualified but the second feature is inspected to be unqualified, the structural part 4 is unqualified.

[0035] The first inspection area 21 includes: a first mounting seat 22, a first inspection column 23 mounted on the top of the first mounting seat 22, and a second inspection column 24 mounted on the top of the first inspection column 23; the outer diameter of the first inspection column 23 is greater than the outer diameter of the second inspection column 24; the difference between the outer diameters of the first inspection column 23 and the second inspection column 24 is between 0.05 - 0.15 mm.

[0036] The second inspection area 31 includes: a second mounting seat 32, a third inspection column 33 mounted on the top of the second mounting seat 32; the third inspection column 33 is successively provided with a first inspection groove 331 and a second inspection groove 332 from bottom to top; the first inspection groove 331 and the second inspection groove 332 are communicated with each other, and the aperture of the first inspection groove 331 is smaller than the aperture of the second inspection groove 332; the difference between the apertures of the first inspection groove 331 and the second inspection groove 332 is between 1 - 1.5 mm.

[0037] Taking a certain model of structural part 4 as an example, as Figures 1-3 shown, the structural part 4 includes a 27.5 mm square inner hole and three external threads. Among them, the middle thread is a key dimension, and the width of the middle thread is 7 mm. Correspondingly, the outer diameter of the first inspection column 23 is set to 27.8 mm, the outer diameter of the second inspection column 24 is set to 27.6 mm, the size of the first inspection groove 331 is set to 8.1 mm, and the size of the second inspection groove 332 is set to 6.9 mm.

[0038] During inspection, the structural member 4 is reversely installed on the second inspection column 24. If the structural member 4 completely passes through the second inspection column 24 but fails to pass through the first inspection column 23, the structural member 4 is qualified; if the structural member 4 fails to pass through the first inspection column 23 or the structural member 4 passes through the second inspection column 24, the structural member 4 is unqualified;

[0039] After the reverse inspection is qualified, the structural member 4 is installed forward on the second inspection column 24. At this time, the intermediate tooth can just be stuck into the second inspection groove 332. If the intermediate tooth completely passes through the second inspection groove 332 but fails to pass through the first inspection groove 331, the structural member 4 is qualified; if the intermediate tooth fails to pass through the second inspection groove 332 or can pass through the first inspection groove 331, the structural member 4 is unqualified;

[0040] When the results of both the forward inspection and the reverse inspection are qualified, the structural member 4 is a qualified structural member 4; when any one of the inspection results is unqualified, the structural member 4 is an unqualified structural member 4.

[0041] As can be seen from the above description, in the embodiment of the present application, the first inspection block 2 and the second inspection block 3 are respectively used to inspect the first feature and the second feature of the structural member 4. Through the base 1, the first inspection block 2 is disposed on one side of the top of the base 1; the second inspection block 3 is disposed on the other side of the top of the base 1; the first inspection block 2 has a first inspection area 21 for inspecting the first feature of the structural member 4; the second inspection block 3 has a second inspection area 31 for inspecting the second feature of the structural member 4, achieving the purpose of respectively inspecting the first feature and the second feature of the structural member 4, thereby realizing the technical effect of improving the inspection efficiency without switching different inspection toolings, and further solving the technical problem of low inspection efficiency caused by only being able to inspect the inner hole of the structural member 4.

[0042] Preferably, the first mounting seat 22, the first inspection column 23, and the second inspection column 24 are integrally formed; the second mounting seat 32 and the third inspection column 33 are integrally formed.

[0043] Preferably, the first mounting seat 22 is detachably connected to the first inspection column 23, the first inspection column 23 is detachably connected to the second inspection column 24; the second mounting seat 32 is detachably connected to the third inspection column 33.

[0044] Preferably, there is a first guiding angle 25 between the first inspection column 23 and the second inspection column 24, facilitating the sliding of the structural member 4 from the first inspection column 23 to the second inspection column 24; there is a second guiding angle 333 between the first inspection groove 331 and the second inspection groove 332, facilitating the sliding of the structural member 4 from the first inspection groove 331 into the second inspection groove 332; the top of the second inspection column 24 has an upward-facing frustum of a cone, facilitating the alignment of the square inner hole of the structural member 4 with the second inspection column 24 and the insertion of the workpiece.

[0045] Preferably, there is an inspection gap between the first inspection block 2 and the second inspection block 3, and the inspection gap is adapted to the structural member 4. As Figures 2-3 shown, in this embodiment, the square inner hole of the structural member 4 is aligned with the first inspection post 23, and the middle teeth of the structural member 4 are aligned with the second inspection post 24. If the square inner hole of the structural member 4 can just pass through the first inspection post 23 but cannot pass through the second inspection post 24, and the middle teeth can just pass through the first inspection groove 331 but cannot pass through the second inspection groove 332, then the structural member 4 is a qualified structural member 4; otherwise, the structural member 4 is unqualified. Such a design can inspect the middle teeth of the structural member 4 while inspecting the square inner hole of the structural member 4, greatly improving the inspection efficiency.

[0046] Preferably, the first inspection post 23 and the second inspection post 24 are square; the third inspection post 33 is circular, and this shape is adapted to the shape of the structural member 4.

[0047] Preferably, the base 1 includes: a bottom plate 11, and a top plate 12 detachably installed on the top of the bottom plate 11, which is convenient to replace the top plate 12 according to needs; first waist holes 121 and second waist holes 122 are oppositely formed on the top plate 12; the first mounting seat 22 is connected to the first waist hole 121 by a bolt; the second mounting seat 32 is connected to the second waist hole 122 by a bolt. When inspecting structural members 4 of different sizes, the positions of the first mounting seat 22 and the second mounting seat 32 relative to the first waist hole 121 or the second waist hole 122 can be adjusted according to needs; during adjustment, first loosen the bolt, then place the structural member 4 on the first inspection block 2 and the second inspection block 3, so that the positions of the first inspection block 2 and the second inspection block 3 can just be adapted to the structural member 4, then tighten the bolt, and then remove the structural member 4, and the adjustment is completed; third waist holes and fourth waist holes are formed on the bottom plate 11 at positions corresponding to the top plate 12, so that the bolt can pass through the first waist hole 121 and the second waist hole 122 at the same time, and can pass through the third waist hole and the fourth waist hole at the same time. In this way, the bolt can fix the mounting seat on the one hand and fix the bottom plate 11 and the top plate 12 on the other hand.

[0048] Preferably, a connecting block 13 is fixedly installed at the bottom of the bottom plate 11. A polygonal sub-connecting hole is formed on one side of the connecting block 13, and a circular hole is formed on the other side; the connecting block 13 is hinged with a hinged rod 14. A polygonal mother-connecting hole is formed on one side of the hinged rod 14, and a circular hole is formed on the other side; the polygonal sub-connecting hole matches the polygonal mother-connecting hole. A connecting bolt is inserted into the circular holes of the connecting block 13 and the hinged rod 14 at the same time, so that the connecting block 13 and the hinged rod 14 can rotate relative to each other; by inserting the polygonal pin 15 into the polygonal mother-connecting hole and the polygonal sub-connecting hole at the same time, the connecting block 13 and the hinged rod 14 can be fixedly connected; when it is necessary to adjust the angle between the connecting block 13 and the hinged rod 14, take out the polygonal pin 15, then rotate the bottom plate 11, and then insert the polygonal pin 15 again after the rotation is completed. The angle of the traditional go-no-go gauge inspection tooling cannot be adjusted. And the inspectors will get tired after a long inspection time. It is impossible to adjust the posture. In addition, due to the different heights of the inspectors, the suitable inspection angles are also different. This device enables the inspectors to adjust to a suitable angle according to their own needs, improving the use experience.

[0049] The other end of the hinged rod 14 is fixedly connected with a telescopic member 16; the telescopic member 16 is composed of a support plate 161 fixedly connected with the hinged rod 14, a first rod body 162 fixedly installed at the bottom of the support plate 161, a second rod body 163 slidably connected with the first rod body 162, and a knob 164 rotatably passing through the second rod body 163 and abutting against the first rod body 162. When it is necessary to adjust the height, first rotate the knob 164 to separate the knob 164 from the second rod body 163, then pull the base 1, and after pulling to the appropriate position, tighten the knob 164 again. The staff can adjust the height according to their needs; moreover, both the angle adjustment and the height adjustment are very simple.

[0050] In this embodiment, the detachable connection can be common connection methods such as snap connection and bolt connection.

[0051] Optionally, the outer diameter of the bottom of the first inspection column 23 to the outer diameter of the top of the second inspection column 24 gradually decreases to form a continuous whole. A mark can be made at the connection between the first inspection column 23 and the second inspection column 24 to determine whether the structural member 4 can pass through the second inspection column 24. Since the outer diameter of the bottom of the first inspection column 23 to the outer diameter of the top of the second inspection column 24 gradually decreases, after the structural member 4 passes through the first inspection column 23, it will naturally move towards the second inspection column 24, avoiding the situation that the structural member 4 is not easy to transition from the first inspection column 23 to the second inspection column 24 due to deviation during the downward movement, such as the bottom of the inner hole of the workpiece abuts against the top of the second inspection column 24, making the staff think that the workpiece cannot pass through the second inspection column 24; similarly, the first inspection groove 331 and the second inspection groove 332 can be designed as continuous grooves and marks can be made at the connection.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
