Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub runout detection, in particular to a runout detection device for a spindle tooling. Background Art

[0002] The wheel hub is a cylindrical metal part that supports the tire with its inner profile and is centrally mounted on an axle.

[0003] The wheel hub is an important part of the vehicle drive system. The wheel hub will deform during the production, processing and heat treatment process, resulting in deviations in the shape and size of the wheel hub, which requires the use of testing equipment to detect its runout. The current testing equipment will extend the main shaft into the center hole of the wheel hub and contact the wheel hub flange position, and then clamp the main shaft through the positioning slider to limit the wheel hub on the main shaft. This limiting method causes a height difference between the positioning slider and the main shaft, resulting in a M-shaped gap at the flange position, which makes it impossible for the main shaft and the hub flange position to fully fit. This results in inaccurate positioning of the wheel hub during runout detection, which in turn affects the accuracy of the wheel hub runout detection. Utility Model Content

[0004] The utility model aims to solve the problem of height difference between a positioning slide block and a main shaft during hub runout detection in the prior art, and proposes a main shaft jig runout detection device.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A spindle jig runout detection device comprises a spindle 1 which is arranged on the detection device and extends into the center hole of a wheel hub, a rubber sleeve 2 is sleeved on the wheel hub, and a limit strip 3 which is circumferentially distributed and extends into the wheel hub wire groove is arranged on the rubber sleeve 2;

[0022] A movable plate 5 is provided in the sliding sleeve of the limit bar 3, and a limit plate 6 is fixedly installed on the movable plate 5 to resist the main rod 1. A slide groove 4 for guiding the movable rod 9 is provided on the limit bar 3. The limit plate 6 and the movable plate 5 extend to the upper end position outside the limit bar 3, and the limit plate 6 is an arc-shaped structure adapted to the main rod 1. When the movable plate 5 slides in the slide groove 4, the limit plate 6 is driven to gradually approach the main rod 1 and surround the main rod 1. By setting the limit plate 6 as an arc-shaped structure adapted to the main rod 1, the contact area between the limit plate 6 and the main rod 1 is increased.

[0023] A clamping sleeve 7 is provided on the limit plate 6 for sliding, and a positioning plate 8 extending to the wheel hub is fixedly installed on the clamping sleeve 7, and a moving rod 9 evenly distributed is provided on the sliding sleeve of the positioning plate 8, and a bracket 11 is fixedly installed on the moving rod 9, and the clamping sleeve 7 is an annular structure, and the bracket 11 and the moving rod 9 extend to the upper end position outside the clamping sleeve 7. By setting the clamping sleeve 7 on the limit plate 6, the clamping sleeve 7 can surround and clamp the limit plate 6, and then the positioning plate 8 is driven by the clamping sleeve 7 to cover the position on one side of the main rod 1, thereby increasing the contact degree between the positioning plate 8 and the wheel hub;

[0024] A pressure plate 10 is fixedly installed on the moving rod 9, which extends into the wheel hub wire groove and movably contacts the limit strip 3 and the moving plate 5. The pressure plate 10 and the moving rod 9 extend to the lower end position outside the positioning plate 8. The positioning plate 8 is vertically arranged on one side of the wheel hub. By applying pressure to the bracket 11, the bracket 11 drives the moving rod 9 to slide on the positioning plate 8. When the moving rod 9 moves, it drives the pressure plate 10 to extend into the wheel hub wire groove. When the pressure plate 10 moves downward, it can press and limit the limit strip 3 and the moving plate 5, so that the M-shaped gap can be covered by the pressure plate 10;

[0025] A connecting plate 12 is connected to the main rod 1 by screws, a reinforcing rod 13 extending to the connecting plate 12 is provided on the clamping sleeve 7, and a bolt corresponding to the connecting plate 12 is provided on the reinforcing rod 13. A guide groove is opened on the clamping sleeve 7, and a connecting ear 14 extending into the guide groove is fixedly installed on the bracket 11, and a fixing bolt corresponding to the bracket 11 is threadedly connected on the connecting ear 14. The position of the clamping sleeve 7 can be locked by the mutual cooperation of the reinforcing rod 13 and the connecting plate 12. When the clamping sleeve 7 is clamping the limit plate 6, the pressure plate 10 can cover the M-shaped gap, so that the main rod 1 can be positioned more accurately when driving the wheel hub runout detection, thereby improving the accuracy of the wheel hub runout detection.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] The rubber sleeve 2 is mounted on the wheel hub, so that the rubber sleeve 2 drives the limit strip 3 to extend into the wheel hub wire groove, and applies pressure to the movable plate 5, so that when the multiple movable plates 5 slide in the slide groove 4, the limit strip 6 is driven to apply pressure to the main rod 1;

[0028] The clamping sleeve 7 is sleeved on the limiting plate 6, so that the clamping sleeve 7 surrounds the limiting plate 6 distributed in the circumferential direction by clamping;

[0029] Connect the connecting plate 12 and the main rod 1 by screws, so that the reinforcing rod 13 on the sleeve 7 extends into the connecting plate 12, and use bolts to lock the reinforcing rod 13 on the connecting plate 12;

[0030] The bracket 11 is pressed, so that the bracket 11 drives the moving rod 9 to slide on the positioning plate 8, and the moving rod 9 drives the pressure plate 10 to move downward. When the pressure plate 10 moves downward, it extends to the limit strip 3 and resists the moving plate 5;

[0031] At the same time, the bracket 11 drives the connecting ear 14 to extend into the guide groove, and the connecting ear 14 is connected to the bracket 11 using a fixing bolt;

[0032] After the detection device is powered on, the main rod 1 drives the wheel hub to rotate, and the detection device can perform a runout detection on the wheel hub.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
