Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub blank processing, in particular to a simple automobile wheel hub valve hole size detection tool. Background Art

[0002] As one of the most important safety components of a car, the wheel hub not only bears the weight of the car, but also needs to withstand the irregular stress generated by various dynamic loads from all directions during driving due to starting, braking, turning, wind resistance, stone impact, uneven road surface, etc., and these stress loads will be partially absorbed by the tire. However, if the tire is deflated or leaking, the driving risk factor will increase.

[0003] The size of the valve hole in wheel hub production will directly affect the installation accuracy of the valve mouth. Improper size will cause air leakage or cause cracks due to insufficient strength of the valve hole. Therefore, the valve hole size is 100% inspected. The current measurement method is to use a depth gauge and a plug to first measure the depth of the valve hole, and then measure the valve hole thickness by measuring the valve hole depth. The diameter of the valve needs to be measured with a vernier caliper. Although this measurement is accurate, it is cumbersome to operate.

[0004] Existing valve hole detection tools need to measure both the valve hole score depth and the hole depth for valve hole thickness detection, and then calculate the valve hole thickness. This requires the use of a depth gauge and a plug at the same time, and calculations are required, and the process is relatively cumbersome. The diameter of the valve hole requires a vernier caliper to measure the inner diameter of the main valve hole, which is inconvenient to operate and easily causes inaccurate readings. In this way, three measuring tools must be used to detect whether the size of the valve hole is qualified, which not only wastes manpower but also greatly reduces the productivity of the production line. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 2The utility model provides an embodiment: a simple automobile wheel hub valve hole size detection tool, including a baffle 1, a first-order column 2 is fixedly connected to the middle of the top of the baffle 1, a second-order column 3 is fixedly connected to the middle of the top of the first-order column 2, a measuring column 4 is fixedly connected to the middle of the top of the second-order column 3, a first-level U-shaped groove 5 is opened in the middle and lower part of the outer side of the measuring column 4, a second-level U-shaped groove 6 is opened in the middle and upper part of the outer side of the measuring column 4, and a guide ball 7 is fixedly connected to the middle of the top of the measuring column 4. The worker puts the sling 13 on the wrist, and then the worker holds the anti-slip rubber pad 9 on the handle 8. The anti-slip groove prevents the detection tool from falling off the hand during use. At the same time, the sling 13 on the wrist can hang the fallen detection tool on the wrist to prevent the detection tool from being damaged by hitting the ground. Then, the detection tool is inserted into the valve hole under the guidance of the guide ball 7. First, the primary U-shaped groove 5 and the secondary U-shaped groove 6 are placed in the sides of the valve hole in turn. When the secondary U-shaped groove 6 cannot enter, the primary U-shaped groove 5 can just enter, then it is determined that the thickness size of the valve hole is qualified. If the secondary U-shaped groove 6 is put in, or the primary U-shaped groove 5 cannot be put in, it is considered that the size is unqualified.

[0032] Reference Figure 1 and Figure 3-Figure 4 A handle 8 is fixedly connected to the middle part of the bottom end of the baffle 1, and a tail stock 10 is fixedly connected to the bottom end of the handle 8. A non-slip rubber pad 9 is inserted into the outside of the handle 8. A hanging ring seat 11 is threadedly connected to the middle part of the bottom end of the tail stock 10. A hanging ring 12 is rotatably connected to the bottom end of the hanging ring seat 11, and a sling 13 is inserted into the middle part of the inner side of the hanging ring 12. Then insert the stepped cylindrical detection tool into the valve hole. If the second-order column 3 passes through smoothly and the first-order column 2 does not pass through, the valve hole diameter size is qualified. If the second-order column 3 cannot pass through or the first-order column 2 passes through, they are both deemed unqualified.

[0033] Reference Figure 1-Figure 4 The top outer side of the first-order column 2 is chamfered, the top outer side of the second-order column 3 is chamfered, the anti-slip rubber pad 9 is made of hard rubber material, the anti-slip rubber pad 9 is provided with an anti-slip groove on the outside, a threaded hole is provided in the middle of the bottom end of the handle 8, a threaded column is fixedly connected to the middle of the top end of the hanging ring seat 11, and a rotating groove is provided in the middle of the bottom end of the hanging ring seat 11. The sling 13 is a ring rope woven with acrylic fiber. After use, the worker only needs to hang the sling 13 on the detection tool on the hook on the tool rack to reduce the damage rate of the detection tool.

[0034] Working principle: the worker puts the sling 13 on the wrist, and then the worker holds the anti-skid rubber pad 9 on the handle 8. The anti-skid groove on the anti-skid rubber pad 9 prevents the detection tool from falling off the hand during use. At the same time, the sling 13 on the wrist can hang the dropped detection tool on the wrist to prevent the detection tool from being damaged by hitting the ground. Then, the detection tool is inserted into the valve hole under the guidance of the guide ball 7. First, the primary U-shaped groove 5 and the secondary U-shaped groove 6 are respectively placed in the sides of the valve hole. When the secondary U-shaped groove 6 cannot enter, the primary U-shaped groove 5 can just enter, then it is determined that the thickness of the valve hole is qualified. If the secondary U-shaped groove 6 is put in, or the primary U-shaped groove 5 cannot be put in, it is considered that the size is unqualified. Then insert the stepped cylindrical detection tool into the valve hole. If the second-order column 3 passes through smoothly but the first-order column 2 does not, the valve hole diameter is qualified. If the second-order column 3 cannot pass through or the first-order column 2 passes through, both are considered unqualified. After use, the worker only needs to hang the sling 13 on the detection tool on the hook on the tool rack to reduce the damage rate of the detection tool.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
