[0002] The main functions of bearings are to bear loads and provide precise guidance for the rotation of the wheel hubs. They bear both axial loads and radial loads, and are very important components. Automotive bearings are a large part of the bearing industry, including wheel hub bearings, air-conditioning fan bearings, pulley bearings, etc., and are divided into high-speed automotive bearings and low-speed automotive bearings. However, no matter what kind of bearing, when it is processed and manufactured, the outer ring raceway needs to be processed by cutting tools.

[0003] Although the existing fixing devices for high-precision bearing processing tools can meet the processing requirements to a certain extent, there are still some defects and deficiencies. When the tool processes the bearing, if the clamping part does not match the shape of the tool, it may cause the tool to shift during the processing, affecting the processing accuracy of the final workpiece. In view of this technical problem, this application proposes a fixing device for high-precision bearing processing tools. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Refer to Figures 5 - 7 , an embodiment provided by the present utility model: a fixing device for a high-precision bearing processing tool, including a mounting base 1. A connecting column 14 is arranged inside the mounting base 1. Two engaging pieces 15 are arranged inside the connecting column 14. The adjacent sides of the two engaging pieces 15 are connected by a spring 16. The top of the connecting column 14 is fixedly connected to an adjusting base 2. On the left and right sides of the top of the adjusting base 2, first clamping pieces 3 are arranged. In the middle of the top of the adjusting base 2, two protective shells 8 are fixedly connected. Inside each of the two protective shells 8, a mounting plate 5 is connected through a lifting arm 7. At the bottom of each of the two mounting plates 5, a second clamping piece 4 is connected through a positioning pin 13. An engaging groove 17 is opened inside the mounting base 1. The engaging piece 15 is arranged inside the engaging groove 17. On the top of each of the two protective shells 8, a rotating handle 9 is arranged. The bottom of the rotating handle 9 is fixedly connected to the top end of a threaded rod 10;

[0028] Specifically, install the tool required for bearing processing between the first clamping member 3 and the second clamping member 4. Since the first clamping member 3 and the second clamping member 4 are installed at both ends of the device, tools with two different processing effects can be installed. When different processing of the bearing is required, by rotating the adjustment base 2, due to external force, the engaging members 15 inside the mounting base 1 will be under the pressure of the special nature of the engaging groove 17, causing the spring 16 between the two engaging members 15 to deform, resulting in the engaging members 15 retracting into the inside of the connecting column 14, so that the connecting column 14 drives the adjustment base 2 to rotate inside the mounting base 1. When the engaging member 15 inside the connecting column 14 reaches the engaging groove 17 inside the mounting base 1 again, it is pushed into the engaging groove 17 by the action of the internal spring 16 to be engaged, that is, the switching of the tool above the adjustment base 2 is completed.

[0029] Refer to Figure 3 and Figure 4 , in which threaded rods 10 are rotatably connected to both the left and right sides inside the protective shell 8. Lifting arms 7 are threadedly connected to the outer circumferences of the two threaded rods 10. The right sides of the bottoms of the two lifting arms 7 are fixedly connected to the top of the mounting plate 5. Gears 12 are fixedly connected to the upper ends of the outer circumferences of the two threaded rods 10. The outer circumferences of the two gears 12 are connected by a synchronous rack 11. The inner walls of the outer circumferences of the two gears 12 are meshed with the synchronous rack 11. Chutes are provided on both the upper left and right sides of the adjustment base 2. The right ends of the lifting arms 7 are slidably connected inside the chutes;

[0030] Specifically, when the tool needs to be replaced, by rotating the rotary handle 9, the threaded rod 10 and the gear 12 connected thereto below are rotated. When the gear 12 rotates, it drives the gear 12 on the other threaded rod 10 to rotate together through the synchronous rack 11 engaged therewith, so that the lifting arm 7 on the threaded rod 10 drives the mounting plate 5 to rise, destroying the clamping state of the second clamping member 4 on the tool below the mounting plate 5, so as to disassemble and replace the tool.

[0031] Refer to Figure 1 and Figure 2 , in which positioning pins 13 are fixedly connected to both the top of the second clamping member 4 and the bottom of the first clamping member 3, and a connecting member 6 is provided on the top of the mounting plate 5. The outer circumference of the connecting member 6 is threadedly connected inside the positioning pin 13. A connecting groove is provided on the top of the mounting plate 5. The second clamping member 4 is arranged inside the connecting groove;

[0032] Specifically, after the second clamping member 4 is separated from the tool through the mounting plate 5, the tool is removed. By rotating the connecting member 6, it is removed from the inside of the positioning pin 13 at the top of the second clamping member 4. At this time, the second clamping member 4 can be disassembled from below the mounting plate 5. After removing the tool from the first clamping member 3, the first clamping member 3 can be removed from the adjusting base 2 by lifting the first clamping member 3. Then, the first clamping member 3 and the second clamping member 4 that match the shape of the replaced tool are installed in their original positions.

[0033] Working principle: When different machining operations need to be performed on the bearing, by rotating the adjusting base 2, the spring 16 between the two engaging members 15 is deformed, causing the engaging members 15 to retract into the connecting column 14. As a result, the connecting column 14 drives the adjusting base 2 to rotate inside the mounting base 1. When the engaging member 15 inside the connecting column 14 reaches the engaging groove 17 inside the mounting base 1 again, the spring 16 inside it will push it into the engaging groove 17 to engage, thus completing the switching of the tool above the adjusting base 2. When the tool needs to be replaced, by rotating the rotary handle 9, the threaded rod 10 and the gear 12 connected to it below rotate. When the gear 12 rotates, it drives another gear 12 to rotate together through the synchronizing rack 11 engaged with it, causing the lifting arm 7 on the threaded rod 10 to drive the mounting plate 5 to rise, thereby disassembling and replacing the tool. After the second clamping member 4 is separated from the tool through the mounting plate 5, the tool is removed. By rotating the connecting member 6, it is removed from the inside of the positioning pin 13 at the top of the second clamping member 4. At this time, the second clamping member 4 can be disassembled from below the mounting plate 5. Then, the first clamping member 3 and the second clamping member 4 that match the shape of the replaced tool are installed in their original positions.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
