[0002] In recent years, as users' requirements for heavy trucks to change oil every 300,000 or 600,000 kilometers and maintenance-free are becoming increasingly strong, the quality requirements for wheel hub assembly parts are also getting higher and higher, which is conducive to the large-scale and wider use of maintenance-free wheel hub assemblies. In order to ensure the quality of oil seals and ABS gear rings in wheel hub assemblies, improve the service life and performance of wheel hub assemblies, and improve the quality of factory inspection, it is necessary to strengthen the inspection of the end face runout of oil seals and ABS gear rings. The inner diameter of the bearing unit in the wheel hub assembly is different, and the tooling used for the oil seal and ABS gear ring end face runout that need to be inspected is different. In addition, in order to improve the inspection quality, it is necessary to appropriately increase the inspection frequency. If the tooling used is different, the inspection tooling needs to be frequently replaced, which is cumbersome. In order to meet the needs of bearing unit inspection of different diameters, a new type of auxiliary tooling for oil seal and ABS gear ring end face runout inspection with strong compatibility and reduced labor time is urgently needed to replace the original special single-type inspection auxiliary tooling that needs to be frequently replaced.

[0036] The embodiment of the present application discloses a novel auxiliary tool for detecting end face runout of an oil seal gear ring.

[0037] Example

[0038] according to Figures 1 to 10 As shown, a novel auxiliary tooling for detecting end face runout of an oil seal gear ring comprises a fixed column 1, a cavity 16 is arranged inside the fixed column 1, an adjusting bolt 7 is vertically inserted at the top of the fixed column 1, the adjusting bolt 7 is threadedly connected to the fixed column 1, a slider 8 is fixedly connected to the lower end of the adjusting bolt 7, the slider 8 is located in the cavity 16, four inclined surfaces A10 are arranged at intervals along the circumferential direction on the outer side of the slider 8, four channels 17 corresponding to the inclined surfaces A10 are arranged at intervals along the circumferential direction on the outer side of the fixed column 1, a rising block 12 is inserted in the channel 17, an inclined surface B11 is arranged on the side surface of one end of the rising block 12 close to the slider 8, the inclined surface B11 abuts against the inclined surface A10, four guide blocks 15 are arranged at intervals along the circumferential direction on the outer side of the slider 8, the inclined surface A10 and the guide block 15 are arranged crosswise, the end of the rising block 12 is located between two adjacent guide blocks 15, the outer side of the guide block 15 is arc-shaped, and the guide block 15 slides up and down along the inner side wall of the fixed column 1.

[0039] The outer side of the expansion block 12 is sleeved with a spring 9, and the outer side of the expansion block 12 close to the slider 8 is sleeved with a fixed limit ring A13, the side of the limit ring A13 contacts the end of the spring 9 for limit, and the diameter of the limit ring A13 is larger than the diameter of the spring 9. The channel 17 is fixedly connected with a limit ring B14, and the side of the limit ring B14 is fixedly connected with the end of the spring 9 away from the slider 8. The adjusting bolt 7 drives the slider 8 to move up and down, and drives the expansion block 12 to move back and forth in the horizontal direction, so that the end of the expansion block 12 tightens the inner diameter of the bearing in the wheel hub assembly 22.

[0040] The bottom of the fixed column 1 is fixedly connected with the base 2, and the base 2 includes an upper disc 5 and a lower disc 6. The diameter of the upper disc 5 is larger than the diameter of the fixed column 1, and the diameter of the lower disc 6 is larger than the diameter of the upper disc 5. The fixed column 1 includes an upper column 3 and a lower column 4. The upper column 3 and the lower column 4 symmetrically divide the cavity 16 and the channel 17. The top of the upper column 3 is provided with a threaded hole 18, and the adjusting bolt 7 is threadedly connected with the threaded hole 18. The upper column 3 and the lower column 4 are fixedly connected by four fixing bolts 19. The adjusting bolt 7 is located at the center of the four fixing bolts 19. The bottom of the lower column 4 is fixedly connected with a guide column 20, and the top of the upper disc 5 is provided with a mounting hole 21, and the guide column 20 is inserted into the mounting hole 21.

[0041] The tooling in the utility model is simple to operate and has good compatibility. It can be applicable to the inner hole diameter size range of the bearing unit in the hub unit from Φ86 to Φ105mm. One set of tooling can simultaneously meet the use of 10 types of hub assemblies 22. It can effectively solve the problem of repeated switching of tooling due to the change of the inner hole diameter size of the bearing unit in the hub assembly 22 during detection, and reduce a large amount of labor time for replacing auxiliary tooling. It saves time and labor, is convenient and quick to operate, and can also simultaneously meet the auxiliary detection of oil seal assembly and ABS gear ring end face runout, and has strong versatility. The adjusting bolt 7 drives the slider 8 to move up and down by rotating. In the process of moving up and down, the slider 8 makes the inclined surface A10 abut against the inclined surface B11, so that the slider 8 pushes the expansion block 12 to move back and forth, so that the end of the expansion block 12 can hold the inner diameter of the bearing unit in the wheel hub assembly 22 outward, thereby tightening and fixing the wheel hub assembly 22, making it convenient for the subsequent dial indicator to detect the runout of the oil seal end face and the ABS gear ring end face. After the operation is completed, the expansion block 12 can be automatically reset under the action of the spring 9, and the operation is convenient and quick, saving time and effort.

[0042] The fixing column 1 is detachably connected by the upper column 3 and the lower column 4 through the fixing bolt 19, which is convenient for the installation and removal of the adjusting bolt 7, the slider 8, the expansion block 12, the spring 9 and other components, and is also convenient for the subsequent replacement and maintenance of individual components. The base 2 can support the hub assembly 22, so that the hub assembly 22 can be placed on the base 2 to improve the stability during the detection process. The design of the guide column 20 and the mounting hole 21 enables the fixing column 1 to be detachably connected to the base 2, which is convenient for installation and removal.

[0043] The guide block 15 can contribute to the stability of the slider 8 during the up and down movement, and prevent the inclined surface A10 from being offset when the slider 8 moves up and down, so that the slider 8 can drive the expansion block 12 to move back and forth smoothly through the inclined surface A10. The position distribution between the adjusting bolt 7 and the fixing bolt 19 is conducive to improving the stability of the up and down movement of the adjusting bolt 7, and is also conducive to the firmness and stability of the connection between the upper column 3 and the lower column 4. The limiting ring A13 can limit the spring 9, and is also conducive to the expansion block 12 to tighten and fix the inner diameter of the bearing unit outward under the elastic action of the spring 9, thereby improving stability. The limiting ring B14 can limit the spring 9 to prevent the spring 9 from being displaced during the movement of the expansion block 12, so that the spring 9 can always exert elastic force during the movement of the expansion block 12, and ensure that the expansion block 12 can automatically reset after tightening the bearing unit.

[0044] Working principle:

[0045] Put the hub assembly 22 on the auxiliary tooling in a positive direction ( Fig. 9), the lower end face of the hub assembly 22 contacts the upper disc 5 of the base 2, and the adjusting bolt 7 is turned downward. The adjusting bolt 7 drives the slider 8 to move downward. During the downward movement, the slider 8 pushes the extrusion inclined surface B11 through the inclined surface A10, and the slider 8 drives the expansion block 12 to move outward. During the movement, the expansion block 12 compresses the spring 9 through the limit ring A13. After the end of the expansion block 12 moves to the inner diameter of the bearing unit and is tightened, stop turning the adjusting bolt 7. The elastic force of the spring 9 keeps the expansion block 12 in a tightened state. Press the dial indicator head to the inner oil seal end face and the ABS gear ring end face detection point to detect the end face runout. After the detection is completed, rotate the adjusting bolt 7 in the opposite direction. The adjusting bolt 7 drives the slider 8 to move upward. The slider 8 drives the expansion block 12 to move in the opposite direction through the cooperation of the inclined surface A10 and the inclined surface B11. The expansion block 12 gradually breaks away from the inner diameter of the bearing, and the expansion block 12 automatically resets under the elastic action of the spring 9. Finally, place the hub assembly 22 upside down on the base 2 ( Fig.10 ), repeat the above operation and use the dial indicator to detect the vibration of the outer oil seal end face.
