[0028] 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.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A rubber seal trimming machine includes a base 1 and a trimming head 2 disposed above the base 1. A motor 3 is fixedly installed inside the base 1. A disc 4 is rotatably mounted on the base 1. The output shaft end of the motor 3 is fixedly mounted to the bottom surface of the disc 4. The disc 4 has evenly distributed movable openings 5. Evenly distributed knobs 6 are rotatably mounted on the side of the disc 4. The number of sets of knobs 6 is the same as the number of sets of movable openings 5, and the knobs 6 are directly opposite the movable openings 5. A bidirectional lead screw 7 is rotatably mounted in each movable opening 5. The rotating shaft ends of the knobs 6 are respectively connected to the rotating shaft ends of the bidirectional lead screw 7. The base is fixedly installed. Symmetrical adjusting blocks 8 are slidably arranged on each of the movable ports 5. The adjusting blocks 8 are threadedly connected to the bidirectional lead screws 7. An arc plate 9 is snapped onto the top of each adjusting block 8. A top frame 10 is fixedly installed directly above the base 1. An electric telescopic column 11 is fixedly installed on the side of the top frame 10. A movable block 12 is slidably arranged on the top frame 10. The end of the output shaft of the electric telescopic column 11 is fixedly installed to the side of the movable block 12. An electric telescopic column 23 is fixedly installed on the movable block 12. The trimming head 2 is fixedly installed to the end of the output shaft of the electric telescopic column.

[0031] In the rubber seal trimming machine, the base 1 and the top frame 10 are used to support the entire device;

[0032] When trimming the sealing ring, the operator rotates the knob 6 on the side of the disc 4 according to the position and size of the annular groove on the sealing ring. The rotation of the knob 6 drives the double-acting screw 7 to rotate in the movable port 5. When the double-acting screw 7 rotates, the symmetrical adjustment blocks 8, which are threaded to the double-acting screw 7 and slidably set on the movable port 5, will move towards or away from each other along the double-acting screw 7. This will drive the arc plates 9, which are locked on the top of the adjustment blocks 8, to move closer or further away from each other. After adjusting the position of the arc plates 9, the annular groove of the sealing ring is inserted into each arc plate 9. The annular groove of the sealing ring is limited by each arc plate 9.

[0033] Start the electric telescopic column 11 on the side of the top frame 10. The output shaft of the electric telescopic column 11 pushes the movable block 12, which is slidably set on the top frame 10, to move. Adjust the position of the movable block 12, and then start the electric telescopic column 23 on the movable block 12. The output shaft of the electric telescopic column 23 drives the trimming head 2 to move to the appropriate trimming position.

[0034] Start the motor 3 installed in the base 1. The output shaft of the motor 3 rotates and drives the disc 4 fixedly installed thereto to rotate on the base 1. The rotation of the disc 4 drives the sealing ring to rotate. During the rotation of the sealing ring, the edge trimming head 2 performs circumferential edge trimming on the sealing ring.

[0035] Since the arc plate 9 is snapped onto the adjusting block 8, the corresponding arc plate 9 can also be removed according to the size of the sealing ring. Only one arc plate 9 is left above each movable opening 5. Then, the position of the arc plate 9 is adjusted according to the size of the sealing ring. After adjustment, the sealing ring is directly laid on the top edge of each arc plate 9 for limiting, and then the trimming operation can be carried out.

[0036] This rubber seal trimming machine can stably trim seal rings of different sizes, significantly improving trimming efficiency and quality.

[0037] The disc 4 is located on the side of the movable opening 5, and the top frame 10 is located on the side of the movable block 12, both of which are equipped with scales 14;

[0038] Both the disc 4 located on the side of the movable opening 5 and the top frame 10 located on the side of the movable block 12 are equipped with scales 14. When the operator rotates the knob 6 on the side of the disc 4 to move the adjusting block 8 and the arc plate 9, the operator can accurately determine the distance and final position of the arc plate 9 by observing the scale 14 on the side of the movable opening 5. When the electric telescopic column 11 is activated to push the movable block 12 to move on the top frame 10, the operator can accurately control the moving distance of the movable block 12 according to the scale 14 on the side of the top frame 10, thereby determining the position of the trimming head 2. This facilitates precise adjustment of the positions of the arc plate 9 and the trimming head 2, improving the trimming stability and accuracy of the sealing ring.

[0039] A positioning strip 15 is fixedly installed on the bottom side of the arc plate 9, and the positioning strip 15 is directly opposite the scale 14.

[0040] A positioning strip 15 is fixedly installed on the bottom side of the arc plate 9. The positioning strip 15 is directly opposite the scale 14. The operator can observe the scale 14 value corresponding to the positioning strip 15 to more accurately determine the adjustment position of the arc plate 9, further improving the accuracy of the adjustment of the arc plate 9, thereby improving the stability and accuracy of the sealing ring trimming.

[0041] A pad is laid on the surface of the arc plate 9, and the pad is made of rubber.

[0042] The surface of the arc plate 9 is covered with a rubber pad. The rubber material has a certain elasticity and friction. When the sealing ring comes into contact with the pad, the pad can increase the friction between the sealing ring and the sealing ring, making the sealing ring more stable during rotation and less prone to slipping or displacement, thereby further improving the stability and accuracy of the sealing ring trimming.

[0043] A damping mechanism is provided between the knob 6 and the disc 4;

[0044] During equipment operation, a certain amount of vibration will be generated. Since there is a damper between the knob 6 and the disc 4, the damper will hinder the rotation of the knob 6. Even if the equipment vibrates, the knob 6 will not be accidentally deflected due to the vibration, ensuring the stability of the arc plate 9. This will also improve the stability and accuracy of the sealing ring trimming.

[0045] The knob 6 has evenly distributed anti-slip textures.

[0046] The knob 6 has evenly distributed anti-slip textures to facilitate the operator's rotation of the knob 6.

[0047] A controller is provided on the base 1, and the controller is electrically connected to the motor 3, the electric telescopic column 11, and the electric telescopic column 13 respectively.

[0048] The base 1 is equipped with a controller that can automatically control the various components of the device.

[0049] Working principle:

[0050] In the rubber seal trimming machine, the base 1 and the top frame 10 are used to support the entire device;

[0051] When trimming the sealing ring, the operator rotates the knob 6 on the side of the disc 4 according to the position and size of the annular groove on the sealing ring. The rotation of the knob 6 drives the double-acting screw 7 to rotate in the movable port 5. When the double-acting screw 7 rotates, the symmetrical adjustment blocks 8, which are threaded to the double-acting screw 7 and slidably set on the movable port 5, will move towards or away from each other along the double-acting screw 7. This will drive the arc plates 9, which are locked on the top of the adjustment blocks 8, to move closer or further away from each other. After adjusting the position of the arc plates 9, the annular groove of the sealing ring is inserted into each arc plate 9. The annular groove of the sealing ring is limited by each arc plate 9.

[0052] Start the electric telescopic column 11 on the side of the top frame 10. The output shaft of the electric telescopic column 11 pushes the movable block 12, which is slidably set on the top frame 10, to move. Adjust the position of the movable block 12, and then start the electric telescopic column 23 on the movable block 12. The output shaft of the electric telescopic column 23 drives the trimming head 2 to move to the appropriate trimming position.

[0053] Start the motor 3 installed in the base 1. The output shaft of the motor 3 rotates and drives the disc 4 fixedly installed thereto to rotate on the base 1. The rotation of the disc 4 drives the sealing ring to rotate. During the rotation of the sealing ring, the edge trimming head 2 performs circumferential edge trimming on the sealing ring.

[0054] Since the arc plate 9 is snapped onto the adjusting block 8, the corresponding arc plate 9 can also be removed according to the size of the sealing ring. Only one arc plate 9 is left above each movable opening 5. Then, the position of the arc plate 9 is adjusted according to the size of the sealing ring. After adjustment, the sealing ring is directly laid on the top edge of each arc plate 9 for limiting, and then the trimming operation can be carried out.

[0055] This rubber seal trimming machine can stably trim seal rings of different sizes, significantly improving trimming efficiency and quality.

[0056] in,

[0057] Both the disc 4 located on the side of the movable opening 5 and the top frame 10 located on the side of the movable block 12 are equipped with scales 14. When the operator rotates the knob 6 on the side of the disc 4 to move the adjusting block 8 and the arc plate 9, the operator can accurately determine the distance and final position of the arc plate 9 by observing the scale 14 on the side of the movable opening 5. When the electric telescopic column 11 is activated to push the movable block 12 to move on the top frame 10, the operator can accurately control the moving distance of the movable block 12 according to the scale 14 on the side of the top frame 10, thereby determining the position of the trimming head 2. This facilitates the precise adjustment of the positions of the arc plate 9 and the trimming head 2, improving the trimming stability and accuracy of the sealing ring.

[0058] A positioning strip 15 is fixedly installed on the bottom side of the arc plate 9. The positioning strip 15 is directly opposite the scale 14. The operator can observe the scale 14 value corresponding to the positioning strip 15 to more accurately determine the adjustment position of the arc plate 9, further improve the accuracy of the adjustment of the arc plate 9, and thus improve the stability and accuracy of the sealing ring trimming.

[0059] The surface of the arc plate 9 is covered with a rubber pad. The rubber material has a certain elasticity and friction. When the sealing ring comes into contact with the pad, the pad can increase the friction between the sealing ring and the sealing ring, making the sealing ring more stable during rotation and less prone to slipping or displacement, thereby further improving the stability and accuracy of the sealing ring trimming.

[0060] 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.
