Description

Technical Field

[0001] This utility model belongs to the field of wheel hub inspection, specifically relating to a wheel hub end face flatness inspection device. Background Technology

[0002] Many car manufacturers use aluminum alloy wheels directly when launching new cars. However, due to the deformation of the machining reference plane, aluminum alloy wheels will undergo various deformations after casting, which has a great impact on the balance of the wheel. If not properly controlled, it can easily lead to car safety accidents. Therefore, the flatness of the wheel blank is an important indicator for judging the product yield.

[0003] Currently, when inspecting the flatness of the wheel hub end face, the wheel hub is usually placed on a testing plate first. Then, a feeler gauge is used to measure the gap between the wheel hub and the testing plate, and the flatness of the wheel hub end face is judged based on the gap between the wheel hub and the testing plate. For example, a wheel hub blank flatness inspection device disclosed in Chinese Patent Publication No. CN207395642U. However, during the inspection, it is necessary to rely on the inspection experience of the inspector to judge whether the gap between the wheel hub and the testing plate is qualified. As a result, the accuracy of the inspection is often low due to the lack of experience of the inspector. Utility Model Content

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0029] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention.

[0030] Please see Figure 1 As shown, this utility model provides a wheel hub end face flatness detection device, including a worktable 1. A bearing seat 3 and a column 8 are fixedly connected to the upper surface of the worktable 1. A first bearing 4 is fixedly connected to the inner wall of the bearing seat 3. A first cylinder 5 is fixedly connected to the inner ring of the first bearing 4. A detection disk 6 is fixedly connected to the upper surface of the first cylinder 5. A gasket 7 is fixedly connected to the upper surface of the detection disk 6.

[0031] like Figures 2 to 9As shown, a rectangular tube 9 is fixedly connected to the upper surface of the column 8. The rectangular tube 9 has slotted holes 10 on both its upper and lower sides. A first slider 11 is fitted inside the slotted holes 10. A first limiting ring 12 is fitted to both the upper and lower sides of the inner wall of the rectangular tube 9. The inner wall of the first limiting ring 12 is fixedly connected to the outer surface of the first slider 11. A first U-shaped plate 13 is fixedly connected to the upper surface of the rectangular tube 9. A second limiting ring 14 is fitted to the surface of the first U-shaped plate 13. A second slider 15 is fixedly connected to the inner wall of the second limiting ring 14. The left and right sides of the second slider 15 are fitted to the inner walls of the first U-shaped plate 13. A semi-circular groove 16 is provided at the bottom of the first slider 11. A semi-circular block 17 is fitted to the inner wall of the semi-circular groove 16. The diameter of the semi-circular groove 16 is equal to the diameter of the semi-circular block 17. The bottom of the semi-circular block 17 is fixedly connected to the upper surface of the first slider 11. A mounting bracket 18 is fixedly connected to the upper surface of the first U-shaped plate 13. An electronic micrometer 19 is fixedly connected to the front of the mounting bracket 18. A horizontal plate 20 is fitted to the measuring end of the electronic micrometer 19. The back of the horizontal plate 20 is fixedly connected to the front of the second limiting ring 14. A rectangular hole 21 is provided inside the first slider 11. A feeler gauge 22 is fixedly connected to the inner wall of the rectangular hole 21. The bottom of the feeler gauge 22 is fitted to the upper surface of the detection plate 6.

[0032] A connecting post 26 is fixedly connected to the bottom of the detection disk 6. A ring 27 is fixedly connected to the end of the connecting post 26 away from the detection disk 6. The diameter of the ring 27 is larger than the diameter of the detection disk 6, and the axis of the ring 27 coincides with the axis of the detection disk 6.

[0033] In this invention, the first bearing 4 causes the detection disk 6 to rotate around the first cylinder 5. The shim 7 creates a certain gap between the end face of the hub and the detection disk 6. The cooperation of the strip hole 10 and the first limiting ring 12 allows the first slider 11 to move only forward and backward. The second limiting ring 14 allows the second slider 15 to move only upward or downward within the first U-shaped plate 13. When the first slider 11 moves forward or backward, the cooperation of the semicircular groove 16 and the semicircular block 17 causes the horizontal plate 20 to move upward, changing the reading on the electronic micrometer 19. After the hub is placed on the detection disk 6, the gap between the hub and the detection disk 6 is detected by the feeler gauge 22.

[0034] A vertical plate 23 is fixedly connected to the upper surface of the workbench 1, an electric telescopic rod 24 is fixedly connected to the front of the vertical plate 23, and a positioning bracket 25 is fixedly connected to the front of the electric telescopic rod 24.

[0035] like Figure 10 , 11As shown, the positioning bracket 25 includes an arc-shaped plate 251, a connecting block 252, a second U-shaped plate 253, a second cylinder 254, and a second bearing 255. The back of the arc-shaped plate 251 is fixedly connected to the front of the connecting block 252, and the back of the connecting block 252 is fixedly connected to the front of the electric telescopic rod 24. The back of the second U-shaped plate 253 is fixedly connected to the front of the arc-shaped plate 251. The upper and lower sides of the second cylinder 254 are fixedly connected to the inner wall of the second U-shaped plate 253, and the surface of the second cylinder 254 is fixedly connected to the inner ring of the second bearing 255.

[0036] In one specific embodiment, a support leg 2 is fixedly connected to the bottom of the workbench 1.

[0037] In one specific embodiment, when the hub on the detection disc 6 contacts the second bearing 255 on the positioning bracket 25, the hub can be positioned by the positioning bracket 25, thereby enabling the inspection personnel to quickly and accurately align the hub with the first cylinder 5. At the same time, the position of the positioning bracket 25 can be adjusted according to hubs of different sizes by means of the electric telescopic rod 24.

[0038] The working principle of this utility model is as follows:

[0039] Place the wheel hub on the test plate 6 so that the surface of the wheel hub contacts the surface of the second bearing 255. Align the wheel hub with the first cylinder 5 using the positioning bracket 25 and create a certain gap between the wheel hub and the test plate 6 using the shim 7.

[0040] Rotate ring 27 to make the hub rotate around the first cylinder 5, and determine whether the gap between the hub and the detection disc 6 meets the standard. Specifically:

[0041] If the gap between the hub and the test disc 6 meets the standard, the friction between the feeler gauge 22 and the hub is of a specified magnitude. The friction causes the first slider 11 to move a certain distance, and through the cooperation of the semicircular groove 16 and the semicircular block 17, the horizontal plate 20 applies a specified magnitude of thrust to the electronic dial indicator 19. At this time, the value displayed on the electronic dial indicator 19 is the specified value.

[0042] If the gap between the hub and the detection disc 6 is large, the friction between the feeler gauge 22 and the hub is less than the specified value. At this time, the friction reduces the moving distance of the first slider 11, and the cooperation of the semicircular groove 16 and the semicircular block 17 reduces the pushing force applied by the horizontal plate 20 to the electronic dial indicator 19. At this time, the value displayed on the electronic dial indicator 19 is less than the specified value.

[0043] If the gap between the hub and the detection disc 6 is small, the friction between the feeler gauge 22 and the hub is greater than the specified value. At this time, the friction increases the moving distance of the first slider 11, and through the cooperation of the semicircular groove 16 and the semicircular block 17, the thrust applied by the horizontal plate 20 to the electronic dial indicator 19 increases. At this time, the value displayed on the electronic dial indicator 19 is greater than the specified value.

[0044] When inspecting the flatness of the wheel hub end face, the inspector only needs to rotate the wheel hub and observe the reading on the electronic dial indicator 19 to quickly and accurately determine the flatness of the wheel hub end face.
