If the size is out of tolerance, it is easy to cause assembly failure or safety hazard, and needs to be detected 100% in production.

However, in the related art, the three-coordinate measuring machine has high equipment cost, low detection efficiency, complex operation and depends on professional personnel, which is difficult to meet the full detection demand of production line. In addition, the size difference of insert holes of different models of wheel hub is small, and the inspector is easy to cause misjudgment due to standard confusion or fatigue. Therefore, a gauge is needed to complete the detection of the size precision of the insert hole. SUMMARY

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the utility model will be described in further detail below with reference to the drawings.

[0024] It should be noted that the terms "first", "second", and the like (if any) in the specification of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of the utility model consistent with some aspects of the present application.

[0025] The hub is the core support component of the automobile tire, and its structural precision directly affects the safety, stability and assembly reliability of the vehicle. With the upgrading of automobile lightweight and manufacturing process, the hub gradually adopts low pressure casting process, and its structural complexity is improved. The plug-in hole, as a key position for assembling subsequent components such as sensors and air valves, has increasingly strict requirements on size tolerance. If the plug-in hole size is out of tolerance, it may cause the components to be unable to be installed, loose or sealing failure, and further cause safety hazards. Therefore, the plug-in hole size needs to be strictly detected in the hub production process.

[0026] At present, the size detection of the hub plug-in hole in the industry mainly relies on a three-coordinate measuring machine. This technology collects three-dimensional coordinate data of the hole position through a high-precision probe, and analyzes whether the size meets the standard by combining with software. However, the three-coordinate measurement has high cost, and the equipment procurement and maintenance cost is extremely high, especially for small and medium-sized enterprises, which constitutes an economic burden; the single measurement takes a long time, which cannot meet the rapid full detection demand of the production line, and only the quality can be controlled through sampling inspection, which leads to the risk of missing detection; professional technicians are needed for programming and operation, and the detection result depends on the experience of personnel, which is easy to introduce human error; the size difference of the plug-in hole of different types of hubs is small, and the inspector needs to frequently switch the detection standard, which is easy to cause misjudgment due to memory confusion; long-term repeated measurement operation is easy to make the inspector tired, further increasing the misjudgment rate and affecting the quality control.

[0027] The utility model provides a kind of hub insert hole go-stop gauge gauge, to solve the above problems, thereby offer.

[0028] The gauge includes mutually independent insert hole stop gauge and insert hole go gauge;The insert hole stop gauge includes gauge main body 5, gauge handle 6, gauge square column 3, gauge cylinder 1 and gauge reference block 2;Gauge handle 6 is fixed on the upper surface of gauge main body 5;Gauge square column 3 and gauge cylinder 1 are arranged on the lower surface of gauge main body 5;Gauge reference block 2 is distributed on the four edges of the lower surface of gauge main body 5;The position of gauge square column 3 and gauge cylinder 1 is matched with hub insert hole, and the size of gauge square column 3 and gauge cylinder 1 corresponds to the upper difference standard of hub insert hole respectively;The insert hole go gauge includes go gauge main body 11, go gauge handle 12, go square column 9, go cylinder 7 and go reference block 8;Go gauge handle 12 is fixed on the upper surface of go gauge main body 11;Go square column 9 and go cylinder 7 are arranged on the lower surface of go gauge main body 11;Go reference block 8 is distributed on the four edges of the lower surface of go gauge main body 11;The position of go square column 9 and go cylinder 7 is matched with hub insert hole, and the size of go square column 9 and go cylinder 7 corresponds to the lower difference standard of hub insert hole respectively;Wherein, the shape of gauge main body 5 and go gauge main body 11 is similar to quadrilateral, material is steel, and all burrs and flash are removed.

[0029] Detection structure is arranged on the lower surface of gauge main body 5, and operating part is fixed on the upper surface.Gauge handle 6 is fixed on the upper surface of gauge main body 5, for holding when operating.Gauge square column 3 and gauge cylinder 1 are arranged on the lower surface of gauge main body 5, and the position is completely matched with hub insert hole distribution;The size of gauge square column 3 is the upper difference standard (maximum allowable size) of hub insert square hole, and the diameter of gauge cylinder 1 is the upper difference standard of hub insert round hole.Gauge reference block 2 is distributed on the four edges of the lower surface of gauge main body 5, for being attached with hub surface when gauge is placed, to ensure that detection positioning stability.

[0030] The lower surface of the go - gauge fixture body 11 is provided with a detection structure, and the upper surface is fixed with an operating component. The go - gauge fixture handle 12 is fixed on the upper surface of the go - gauge fixture body 11 for holding during operation. The go - gauge square column 9 and the go - gauge cylindrical column 7 are arranged on the lower surface of the go - gauge fixture body 11, and their positions are completely matched with the distribution of the hub plug holes; the size of the go - gauge square column 9 is the lower tolerance standard (the minimum allowable size) of the square hole of the hub plug, and the diameter of the go - gauge cylindrical column 7 is the lower tolerance standard of the round hole of the hub plug. The go - gauge reference blocks 8 are distributed on the four sides of the lower surface of the go - gauge fixture body 11, and their functions are the same as those of the no - go reference blocks 2.

[0031] If the no - go square column 3 and the no - go cylindrical column 1 cannot be inserted into the hub plug hole, and the no - go reference block 2 does not fit the hub surface, it is determined that the hole size does not exceed the upper tolerance limit. If the go - gauge square column 9 and the go - gauge cylindrical column 7 can be completely inserted into the hub plug hole, and the go - gauge reference block 8 fits the hub surface, it is determined that the hole size is not lower than the lower tolerance limit. It is necessary to meet the detection conditions of both the no - go and go - gauge fixtures simultaneously to determine that it is qualified.

[0032] Optionally, 1 no - go square column 3 and 2 no - go cylindrical columns 1 are arranged on the lower surface of the no - go - gauge fixture body 5, and their positions are the same as those of the hub plug holes, which are determined by the 3D model of the hub. 1 go - gauge square column 9 and 2 go - gauge cylindrical columns 7 are arranged on the lower surface of the go - gauge fixture body 11, and their positions are the same as those of the hub plug holes, which are determined by the 3D model of the hub. 4 no - go reference blocks 2 are arranged near the four sides of the lower surface of the no - go - gauge fixture body 5 to achieve a smooth fit between the fixture and the hub; 4 go - gauge reference blocks 8 are arranged in four directions on the lower surface of the go - gauge fixture body 11 to achieve a smooth fit between the fixture and the hub.

[0033] In a possible implementation, the no - go - gauge fixture body 5 and the go - gauge fixture body 11 are of a quadrilateral structure; a no - go weight - reducing cavity 4 is provided between the no - go square column 3 and the no - go cylindrical column 1; a go - gauge weight - reducing cavity 10 is provided between the go - gauge square column 9 and the go - gauge cylindrical column 7.

[0034] The contour of the quadrilateral structure is adapted to the shape of the hub measurement area, ensuring that the fixture can cover the distribution area of the hub plug holes and avoiding missed or misdetected inspections caused by structural misalignment during the detection process. A no - go weight - reducing cavity 4 is provided between the no - go square column 3 and the no - go cylindrical column 1, and a go - gauge weight - reducing cavity 10 is provided between the go - gauge square column 9 and the go - gauge cylindrical column 7. The no - go weight - reducing cavity 4 and the go - gauge weight - reducing cavity 10 are concave structures located between the square column and the cylindrical column on the lower surface of the fixture body. The weight - reducing cavity reduces the overall weight of the fixture by removing part of the material of the main body, improving the operation convenience, and at the same time ensuring that the structural strength of the fixture body is not affected.

[0035] In one possible implementation, the surfaces of the no-go gauge handle 6 and the go gauge handle 12 are provided with anti-slip stripes. These anti-slip stripes are raised or recessed patterns distributed along the length or circumference of the handle and are directly machined onto the handle surface. By increasing the friction between the handle and the operator's hand, the anti-slip stripes prevent the gauge from shifting or falling off during inspection due to hand slippage, thus ensuring operational stability.

[0036] In one possible implementation, the no-go gauge reference block 2 and the go gauge reference block 8 have a planar contact structure to achieve a fit between the fixture body and the wheel hub. The surfaces of the reference blocks that contact the wheel hub are flat surfaces. The no-go gauge reference blocks 2 are distributed on the four sides of the lower surface of the no-go gauge fixture body 5, and the go gauge reference blocks 8 are distributed on the four sides of the lower surface of the go gauge fixture body 11. The planar contact structure ensures that when the fixture is placed, the reference blocks form a gapless, full contact with the wheel hub surface, avoiding measurement errors caused by local tilting or uneven force on the fixture, thereby ensuring the stability and reliability of the test results.

[0037] exist Figure 1 and Figure 2 In the process of fitting the plug-in hole no-go gauge, hold the handle 6 of the no-go gauge with one hand and place the body 5 of the no-go gauge directly above the wheel hub plug-in hole, aligning the no-go gauge square post 3 and the no-go gauge cylinder 1 with the wheel hub plug-in hole, and slowly move it downwards. If the no-go gauge square post 3 and the no-go gauge cylinder 1 cannot completely pass through the plug-in hole, and the no-go gauge reference block 2 cannot fit with the wheel hub, the no-go gauge is deemed to be fit and qualified; otherwise, it is deemed unqualified.

[0038] exist Figure 3 and Figure 4 In the process of fitting the plug-in hole go gauge, grasp the handle 12 of the go gauge with one hand and place the body 11 of the go gauge directly above the wheel hub plug-in hole, aligning the square post 9 and the cylindrical post 7 of the go gauge with the wheel hub plug-in hole. Slowly move it downwards. If the square post 9 and the cylindrical post 7 of the go gauge can enter the plug-in hole and the reference block 8 of the go gauge fits tightly with the wheel hub, the go gauge is deemed to be fit and qualified; otherwise, it is unqualified. Only when both the plug-in hole no-go gauge and the plug-in hole go gauge are fit and qualified can the size of the plug-in hole be deemed qualified, and the process can proceed to the next step.

[0039] In summary, the technical solution provided by this utility model uses independent no-go and go gauges to correspond to the upper and lower tolerances of the wheel hub insertion hole. The no-go gauge square post and no-go gauge cylinder are designed with the upper tolerance; if they cannot be inserted into the hole and the reference block is not in contact with the wheel hub, the hole size is determined to be within the upper limit. The go gauge square post and go gauge cylinder are designed with the lower tolerance; if they can be fully inserted and the reference block is in contact with the wheel hub, the hole size is determined to be within the lower limit. Both go gauge fit and no-go gauge limit must be satisfied simultaneously to ensure that the hole size is strictly controlled within the tolerance zone, eliminating the risk of missed inspections in traditional sampling inspections.

[0040] The square and cylindrical positions of the no-go and go gauges perfectly match the distribution of the wheel hub insertion holes, allowing for coverage of all test holes in a single operation, significantly improving testing efficiency compared to traditional hole-by-hole measurements. The gauge's main body shape adapts to the wheel hub's inspection area contour, ensuring full hole coverage and preventing missed or false inspections due to structural misalignment. Weight-reducing recesses between the square and cylindrical columns of the no-go and go gauges lower the gauge's weight, enhancing operational flexibility while maintaining structural strength. Anti-slip stripes on the handle surface increase friction, preventing gauge shifting or detachment during testing and ensuring operational stability. Four-sided planar contact reference blocks ensure a seamless fit between the gauge and the wheel hub surface, eliminating measurement errors caused by tilting or shifting and improving testing reliability.

[0041] The planar contact reference block forces the inspection tool to align with the hub surface, simplifying the operation logic and avoiding misjudgments caused by inspector fatigue or confusion with standards. Separate use of the go and no-go gauges adapts to different tolerance criteria, avoiding the inspection confusion caused by the complex structure of traditional tools.

[0042] Those skilled in the art will understand that Figures 1-4 The structure shown does not constitute a limitation on the structure of this utility model. It may include more or fewer components than shown, or combine certain components, or use different component arrangements.
