[0002] In the field of machining, ring-shaped parts (such as bearing rings and sealing rings) are widely used in various types of equipment. To ensure their assembly accuracy and performance, their inner and outer circles usually need to be machined simultaneously to ensure concentricity and dimensional accuracy.

[0003] Currently, traditional processing methods often employ a step-by-step processing approach, which involves processing the outer or inner circle first, and then changing tooling or equipment to process the other side. This method is not only inefficient, but also prone to misalignment of the inner and outer circles due to positioning errors, thus affecting product quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing processing methods cannot process the inner and outer rings of annular parts simultaneously, and to propose a device for simultaneously cutting the inner and outer circles of annular parts.

[0005] To achieve the above objectives, the present invention employs the following technology: a device for cutting the inner and outer circles of annular parts simultaneously, comprising a frame and parts, wherein the frame is equipped with a bearing component capable of supporting the parts and a cutting component capable of cutting the parts;

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 6 This embodiment provides a device for cutting the inner and outer circles of an annular part at the same time, including a frame 10 and a part 11. The part 11 is annular in shape. The frame 10 is equipped with a support component 20 that can support the part 11 and a cutting component 30 that can cut the part 11.

[0028] The support assembly 20 includes a support frame 21 fixedly mounted on the frame 10, an annular frame 22 rotatably mounted on the support frame 21, and a part 11 placed on the annular frame 22. The rubber pad on the annular frame 22 can increase the friction between the annular frame 22 and the part 11, so that the annular frame 22 can drive the part 11 to rotate. Teeth 23 are fixedly mounted on the outside of the annular frame 22, and several gears 24 are respectively mounted on the support frame 21. A timing belt 25 meshes between the teeth 23 and the several gears 24. Through the rotation of the gears 24, the timing belt 25 can allow the annular frame 22 to rotate through the teeth 23. A protective frame is set at the top of the support frame 21, and the gears 24 and the timing belt 25 are located inside the protective frame.

[0029] Reference Figure 1 - Figure 4Specifically, in order to allow part 11 to rotate and cooperate with cutting lines 35 and 375 to cut surface burrs, one of the gears 24 is fixedly connected to the output end of the drive unit (a servo motor in the prior art). The drive unit can drive the connected gear 24 to rotate. Box doors are hinged to both sides of the frame 10 to block debris during cutting. A controller is also provided on the frame 10 to control the operation of the carrying assembly 20 and the cutting assembly 30. In use, the annular part 11 is placed on top of the annular frame 22, such as... Figures 3 to 2 As shown, the cutting assembly 30 is moved so that cutting line 35 contacts the outer surface of part 11 and cutting line 375 contacts the inner surface of part 11. Cutting lines 35 and 375 are then rotated. Subsequently, the drive unit is activated to drive the gear 24 connected to it to rotate. The timing belt 25 meshes with the ring frame 22, which rotates through the teeth 23, thereby driving part 11 to rotate. When part 11 rotates one revolution, the outer and inner walls of part 11 can be cut simultaneously by cutting lines 35 and 375 respectively.

[0030] Reference Figure 2 - Figure 6 Specifically, in order to cut the outer wall of part 11, a cutting assembly 30 is provided. The cutting assembly 30 includes a vertical plate 31 fixedly installed on the frame 10, a guide rail 32 symmetrically installed on the vertical plate 31, a fixed frame 33 slidably installed on the guide rail 32, the fixed frame 33 being kept stable during movement by the guide rail 32, a turntable 34 symmetrically arranged on the fixed frame 33, and a cutting wire 35 wound and connected between the two turntables 34. The rotation of the turntables 34 can drive the cutting wire 35 to rotate, and a motor 36 is fixedly installed on the fixed frame 33.

[0031] In more detail, the turntable 34 and the fixed frame 33 are rotatably connected. One of the turntables 34 is fixedly connected to the output end of the motor 36. The motor 36 can drive the turntable 34 connected to it to rotate. The cutting line 35 contacts the outer surface of the part 11. The outer surface of the part 11 can be cut by the rotating cutting line 35.

[0032] Reference Figure 5 Specifically, in order to cut the inner wall of part 11, an inner cutting component 37 is also assembled on the vertical plate 31.

[0033] The inner cutting component 37 includes a second fixed frame 371 that is slidably mounted on the guide rail 32. The first fixed frame 33 and the second fixed frame 371 are respectively fixedly connected to the output end of the electric telescopic rod, thereby driving the movement of the first fixed frame 33 and the second fixed frame 371. Several turntables 372 are rotatably mounted on the second fixed frame 371. A third turntable 373 is set on the second fixed frame 371 by an electric push rod 374. The position of the third turntable 373 can be adjusted by the electric push rod 374. The second cutting line 375 is wound and connected between the several turntables 372 and the third turntable 373. The rotation of the several turntables 372 and the third turntable 373 can make the second cutting line 375 rotate.

[0034] In more detail, the fixing frame 371 is also provided with an auxiliary component 376. The cutting line 375 contacts the roller surface on the auxiliary component 376. The roller on the auxiliary component 376 enables the cutting line 375 to remain stable during cutting, reducing the shaking of the cutting line 375. The cutting line 375 contacts the inner surface of the part 11.

[0035] In more detail, a slide is slidably connected to the second fixed frame 371, and a turntable 373 is rotatably mounted on the slide. The slide is fixedly connected to the output end of the electric actuator 374. After the part 11 is placed, the electric actuator 374 is activated to drive the slide to move. The slide drives the turntable 373 to move. After the turntable 373 moves, the second cutting line 375 will no longer be taut, thus becoming loose. The second cutting line 375 is then moved out from between the turntables 272 and 373. Subsequently, the first fixed frame 33 and the second fixed frame 371 are moved by the electric telescopic rods on both sides. The first fixed frame 33 drives the cutting line. Cutting wire 35 contacts the outer surface of part 11, while fixing bracket 371 drives turntable 372 to move towards part 11, so that part 11 is located between several turntables 372. Then, cutting wire 375 is wound around several turntables 372 and turntable 373 again, so that cutting wire 375 is located inside part 11. Then, the electric push rod 374 drives the slide to reset turntable 373, thereby tightening cutting wire 375 again, so that the tightened cutting wire 375 contacts the inner wall of part 11. Then, the part 11 is cut by rotating cutting wire 35 and cutting wire 375.

[0036] After processing is completed, repeat the above operation to loosen and disassemble the second cutting line 375, then reset the first fixing bracket 33 and the second fixing bracket 371, reinstall the second cutting line 375, and then take out the processed part 11.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
