[0029] 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.

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] A clamping fixture for gear ring machining includes a base 1, a clamping platform 2 above the base 1, symmetrical slide rails 3 on the clamping platform 2, a double-headed motor 4 fixedly mounted in the middle of the clamping platform 2, lead screws 5 rotatably mounted in each slide rail 3, the output shaft ends of the double-headed motor 4 being fixedly mounted to the ends of the lead screws 5 respectively, movable blocks 6 slidably mounted on each slide rail 3, each movable block 6 being threadedly connected to the lead screws 5, pressure blocks 7 being provided on the top surface of each movable block 6, a second symmetrical slide rail 8 on the clamping platform 2, symmetrical electric push rods 9 fixedly mounted on both sides of the clamping platform 2, movable blocks 10 slidably mounted on each slide rail 8, the output shaft ends of the electric push rods 9 being fixedly mounted to the sides of each movable block 10, clamping plates 11 being provided on the top surface of each movable block 10, and both the pressure blocks 7 and the clamping plates 11 being arc-shaped.

[0032] When in use, the base 1 provides stable support for the entire device. When machining the gear ring, the appropriate positioning method should be selected according to the machining position.

[0033] When pressing the inner wall of the shaft hole of the gear ring, the operator installs two sets of pressure blocks 7 on the movable block 6 respectively. Then, the shaft hole of the gear ring to be processed is placed on the clamping table 2 through the two sets of pressure blocks 7. At this time, the double-head motor 4 is started. The output shaft end of the double-head motor 4 drives the lead screw 5 fixedly installed with it to rotate in the slide rail 3. Since the movable block 6 is threadedly connected to the lead screw 5, the rotation of the lead screw 5 will drive the movable block 6 to slide away from each other on the slide rail 3, thereby driving the pressure block 7 on the top surface of the movable block 6 to move away from each other and press the hole. After the shaft hole is pressed and fixed, the gear ring is processed.

[0034] When it is necessary to clamp the outer ring of the gear ring, the operator fixes the two sets of clamping plates 11 on the movable block 2 10 respectively, and then places the gear ring in the middle of the clamping table 2. At this time, the gear ring is located between the two sets of clamping plates 11. At the same time, the electric push rods 9 on both sides of the clamping table 2 are activated. The output shaft end of the electric push rod 9 pushes the movable block 2 10 fixedly installed thereto to slide on the slide rail 2 8. The clamping plates 11 on the top surface of the movable block 2 10 move closer to each other and clamp the outer ring of the gear ring from both sides. After clamping, the gear ring is processed.

[0035] This clamping fixture for gear ring machining can clamp the outer ring of the gear ring separately or press the shaft hole of the gear ring. The clamping position can be flexibly adjusted according to different machining methods, making it highly applicable, significantly improving machining efficiency, and highly practical.

[0036] A pad is laid on the surface of the pressure block 7, and the pad is made of rubber.

[0037] The surface of the pressure block 7 is covered with a rubber pad, which can improve the stability of pressing the gear ring shaft hole.

[0038] The inner wall of the clamp 11 is provided with evenly distributed teeth 12;

[0039] When the clamping plate 11 is used to clamp the outer ring, the teeth 12 on the inner wall of the clamping plate 11 can be embedded in the gear ring, improving the stability of clamping the outer wall of the gear ring.

[0040] Both movable block 6 and movable block 10 are provided with slots 13. The bottom edges of the pressing block 7 and the clamping plate 11 are fixedly installed with insert plates 14. The size of the insert plate 14 is adapted to the size of the slot 13.

[0041] When it is necessary to replace the pressure block 7 or the clamping plate 11, the operator can directly pull out the insert plate 14 of the pressure block 7 or the clamping plate 11 from the insertion port 13 of the movable block 1 6 or the movable block 2 10. Since the size of the insert plate 14 is compatible with the size of the insertion port 13, during installation, simply align the insert plate 14 of the new pressure block 7 or the clamping plate 11 with the insertion port 13 and insert it to complete the simple disassembly and assembly. This makes it easy for the operator to quickly replace the pressure block 7 and the clamping plate 11 of the appropriate size according to the different sizes of the gear rings, so as to meet the processing requirements of different specifications of gear rings, thereby improving the applicability of the device.

[0042] A damper is provided between the insert plate 14 and the socket 13;

[0043] After the insert plate 14 is inserted into the socket 13, the damping between the insert plate 14 and the socket 13 causes the insert plate 14 to be subjected to a certain resistance within the socket 13. This prevents the insert plate 14 from easily coming out of the socket 13 due to vibration, external force, or other factors during the processing, ensuring the stability of the pressure block 7 and the clamping plate 11 after installation. This also prevents the pressure block 7 or the clamping plate 11 from affecting the fixing effect of the gear ring due to loose connection when clamping or pressing the gear ring.

[0044] The clamping table 2 is rotatably mounted on the base 1. The base 1 is provided with a rotating component 15 for driving the clamping table 2 to rotate. The rotating component 15 includes a rotating motor 151 fixedly mounted on the base 1, a gear disk 152 rotatably mounted on the base 1, and an outer gear ring 153 fixedly mounted on the outer wall of the clamping table 2. The output shaft end of the rotating motor 151 is fixedly mounted to the rotating shaft end of the gear disk 152. The gear disk 152 and the outer gear ring 153 are meshed and connected for transmission.

[0045] After the gear ring is fixed on the clamping table 2 by the pressure block 7 or the clamping plate 11, the rotating motor 151 is started. The output shaft of the rotating motor 151 drives the gear plate 152 to rotate. Since the gear plate 152 is meshed and connected to the outer gear ring 153 on the outer wall of the clamping table 2, the rotation of the gear plate 152 drives the outer gear ring 153 to rotate, thereby driving the clamping table 2 to rotate on the base 1, so that the gear ring rotates accordingly. This allows the gear ring to be adjusted to a suitable processing position, further facilitating the processing of the gear ring.

[0046] Working principle:

[0047] When in use, the base 1 provides stable support for the entire device. When machining the gear ring, the appropriate positioning method should be selected according to the machining position.

[0048] When pressing the inner wall of the shaft hole of the gear ring, the operator installs two sets of pressure blocks 7 on the movable block 6 respectively. Then, the shaft hole of the gear ring to be processed is placed on the clamping table 2 through the two sets of pressure blocks 7. At this time, the double-head motor 4 is started. The output shaft end of the double-head motor 4 drives the lead screw 5 fixedly installed with it to rotate in the slide rail 3. Since the movable block 6 is threadedly connected to the lead screw 5, the rotation of the lead screw 5 will drive the movable block 6 to slide away from each other on the slide rail 3, thereby driving the pressure block 7 on the top surface of the movable block 6 to move away from each other and press the hole. After the shaft hole is pressed and fixed, the gear ring is processed.

[0049] When it is necessary to clamp the outer ring of the gear ring, the operator fixes the two sets of clamping plates 11 on the movable block 2 10 respectively, and then places the gear ring in the middle of the clamping table 2. At this time, the gear ring is located between the two sets of clamping plates 11. At the same time, the electric push rods 9 on both sides of the clamping table 2 are activated. The output shaft end of the electric push rod 9 pushes the movable block 2 10 fixedly installed thereto to slide on the slide rail 2 8. The clamping plates 11 on the top surface of the movable block 2 10 move closer to each other and clamp the outer ring of the gear ring from both sides. After clamping, the gear ring is processed.

[0050] This clamping fixture for gear ring machining can clamp the outer ring of the gear ring separately or press the shaft hole of the gear ring. The clamping position can be flexibly adjusted according to different machining methods, making it highly applicable, significantly improving machining efficiency, and highly practical.

[0051] in,

[0052] The surface of the pressure block 7 is covered with a rubber pad, which can improve the stability of pressing the gear ring shaft hole;

[0053] When the clamping plate 11 is used to clamp the outer ring, the teeth 12 on the inner wall of the clamping plate 11 can be embedded in the gear ring, improving the stability of clamping the outer wall of the gear ring.

[0054] When it is necessary to replace the pressure block 7 or the clamping plate 11, the operator can directly pull out the insert plate 14 of the pressure block 7 or the clamping plate 11 from the insertion port 13 of the movable block 1 6 or the movable block 2 10. Since the size of the insert plate 14 is compatible with the size of the insertion port 13, during installation, simply align the insert plate 14 of the new pressure block 7 or the clamping plate 11 with the insertion port 13 and insert it to complete the simple disassembly and assembly. This makes it easy for the operator to quickly replace the pressure block 7 and the clamping plate 11 of the appropriate size according to the different sizes of the gear rings, so as to meet the processing requirements of different specifications of gear rings and thus improve the applicability of the device.

[0055] After the insert plate 14 is inserted into the socket 13, the damping between the insert plate 14 and the socket 13 causes the insert plate 14 to be subjected to a certain resistance in the socket 13. This prevents the insert plate 14 from easily coming out of the socket 13 due to vibration, external force or other factors during the processing, ensuring the stability of the pressure block 7 and the clamping plate 11 after installation. This also prevents the pressure block 7 or the clamping plate 11 from affecting the fixing effect of the gear ring due to loose connection when clamping or pressing the gear ring.

[0056] After the gear ring is fixed on the clamping table 2 by the pressure block 7 or the clamping plate 11, the rotating motor 151 is started. The output shaft of the rotating motor 151 drives the gear plate 152 to rotate. Since the gear plate 152 is meshed and connected to the outer gear ring 153 on the outer wall of the clamping table 2, the rotation of the gear plate 152 drives the outer gear ring 153 to rotate, thereby driving the clamping table 2 to rotate on the base 1, so that the gear ring rotates accordingly. This allows the gear ring to be adjusted to a suitable processing position, further facilitating the processing of the gear ring.

[0057] 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.
