[0049] The pressure rod arm hole grinding assembly also includes a movable frame 19, which is fixedly connected to the sliding frame 18. The right end of the movable frame 19 is fixedly connected to a second drive motor 20. The movable frame 19 is internally rotatably connected to a second threaded rod 21.

The output end of the electric telescopic rod 27 is fixedly connected to the movable seat 24. A fine grinding tool 26 is installed on the upper end of the movable seat 24. A connecting flange 25 is provided at the upper end of the movable seat 24. The internal thread of the connecting flange 25 is connected to a fixing bolt. The movable seat 24 is fixed to the movable seat 24 by the fixing bolt.

[0050] A chip removal groove 29 is provided on the surface of the grinder 2 , and the front side of the chip removal groove 29 is inclined. A chip pusher 28 is fixedly connected to the lower end of the sliding frame 18 , and a chip collection box 30 is provided on the surface of the base 1 .

[0051] The lower end of the grinder 2 is fixedly connected with four supporting legs, which are distributed at the four corners of the bottom of the grinder 2. The lower end of the grinder 2 is fixedly connected with a plurality of reinforcing ribs, which are respectively fixedly connected with the corresponding supporting legs.

[0052] When using the device, first place the flange 8 inside the chuck 7, place the positioning plate 9 on the front side of the flange 8, and use two pins 10 to clamp the flange 8 and the positioning plate 9 to facilitate positioning between the flange 8 and the positioning plate 9, and then place the counterweight 13 on the surface of the flange 8. Through the use of the counterweight 13, it is convenient to counterweight the upper and lower sides of the flange 8, and it is convenient to maintain balance during the rotation of the flange 8, and improve the stability of the flange 8 during rotation. Fix the flange 8 and the positioning plate 9 by multiple fixing bolts, and fix the flange 8 to the chuck 7 at the same time, which is convenient for positioning and fixing the flange 8 and the positioning plate 9, and improves the stability of the flange 8 and the positioning plate 9 during installation.

[0053] Since a groove is provided at the upper end of the positioning disk 9, it is convenient to insert the positioning pin 12 into the flange 8 and the first pressure lever arm positioning pin 11 into the positioning disk 9, and there is an interference fit between the first pressure lever arm positioning pin 11 and the positioning disk 9. The interference fit uses the elasticity of the material to expand and deform the hole on the surface of the positioning disk 9 and sleeve it on the first pressure lever arm positioning pin 11. When the hole on the surface of the positioning disk 9 is restored, a tightening force is generated on the first pressure lever arm positioning pin 11, so that the first pressure lever arm positioning pin 11 and the positioning disk 9 are tightly connected and not easy to fall off, thereby improving the stability of the connection. Due to the tightening force generated by the interference fit, the first pressure lever arm positioning pin 11 and the positioning disk 9 can be tightly connected, thereby effectively preventing the first pressure lever arm positioning pin 11 from rotating in the positioning disk 9.

[0054] Then, the special-shaped pressure lever arm that needs to be ground is sleeved on the first pressure lever arm locating pin 11, and the second pressure lever arm locating pin 14 passes through the grooves on the surface of the special-shaped pressure lever arm and the locating plate 9, and the second pressure lever arm locating pin 14 is inserted into the interior of the locating pin 12, so as to facilitate the positioning of the second pressure lever arm locating pin 14 and the first pressure lever arm locating pin 11, and to facilitate the fixing of the special-shaped pressure lever arm, and the special-shaped pressure lever arm is fixed to the surface of the first pressure lever arm locating pin 11 with a screw 31, and then the second pressure lever arm locating pin 14 is pulled outward to make the second pressure lever arm The arm locating pin 14 is separated from the special-shaped pressure lever arm and 12. Due to the cooperation between the second pressure lever arm locating pin 14 and the locating pin 12, the hole of the special-shaped pressure lever arm is exactly in a straight line with the locating pin 12, that is, the hole of the special-shaped pressure lever arm that needs to be fine-ground is located at the center of the flange 8. Fixing the special-shaped pressure lever arm can ensure its stable position and avoid deviation caused by movement or shaking, thereby improving the fine grinding effect. Stable fixation can prevent the special-shaped pressure lever arm from falling off or moving during the fine grinding process, reducing safety hazards during operation.

[0055] Start the first drive motor 15 to drive the first threaded rod 16 to rotate inside the threaded rod frame 4, the first threaded rod 16 drives the sliding frame 18 to slide inside the threaded rod frame 4, and the sliding frame 18 slides on the surface of the sliding rod 17 and the sliding rod frame 6, start the second drive motor 20 to drive the second threaded rod 21 to rotate, the second threaded rod 21 drives the slider 22 to slide inside the movable frame 19, and the slider 22 drives the mold fixing seat 23 to move. Since the sliding frame 18 is in an "M" shape as a whole, that is, the sliding frame 18 is high on both sides and low in the middle, it is convenient to lower the center of gravity of the sliding frame, and to maintain stability during the movement of the sliding frame 18, ensuring that the movable frame 19 and the mold fixing seat 23 can move smoothly along the predetermined path, which can not only change the movement direction of the movable frame 19 and the mold fixing seat 23, but also provide stable support to ensure the smoothness and safety of the movement of the movable frame 19 and the mold fixing seat 23.

[0056] The mold fixing seat 23 drives the movable seat 24, the connecting flange 25 and the fine grinding hole tool 26 to move. Through the forward and backward movement of the sliding frame 18 and the left and right movement of the mold fixing seat 23, it is convenient to drive the fine grinding hole tool 26 to move in the direction of the special-shaped pressure rod arm. Through the setting of the connecting flange 25 and the movable seat 24, and the fixing of the movable seat 24 and the connecting flange 25 by fixing bolts, it is convenient to limit the fine grinding hole tool 26. Starting the electric telescopic rod 27 drives the movable seat 24 to slide inside the mold fixing seat 23, so as to adjust the height of the fine grinding hole tool 26 according to the height of the hole of the special-shaped pressure rod arm, so that the fine grinding hole tool 26 can contact the inner wall of the hole of the special-shaped pressure rod arm during the movement.

[0057] At the same time, the driving motor on the inner wall of the grinder 2 is started to drive the chuck 7 to rotate, and the chuck 7 drives the flange 8, the positioning plate 9 and the first pressure rod arm positioning pin 11 to rotate, thereby driving the special-shaped pressure rod arm on the surface of the first pressure rod arm positioning pin 11 to rotate, so as to facilitate the fine grinding of the hole of the special-shaped pressure rod arm.

[0058] When the fine-grinding hole tool 26 is used to fine-grind the hole of the special-shaped pressure rod arm, some waste chips will be ground out on the inner wall of the hole of the special-shaped pressure rod arm. After the waste chips are ground out, the waste chips may splash during the rotation of the chuck 7. The arrangement of the first support block 3, the threaded rod frame 4, the second support block 5 and the slide rod frame 6 facilitates the blocking of the waste chips, and facilitates the blocking of the waste chips between the threaded rod frame 4 and the slide rod frame 6 during the fine-grinding hole processing, thereby keeping the working environment clean and tidy. At the same time, it also helps to protect the safety of the operator and prevent accidental injuries caused by waste chips. The openings of the threaded rod frame 4 and the slide rod frame 6 are arranged toward the outside and downward of the grinder 2, which facilitates operation and maintenance, effectively removes chips, improves safety and optimizes the grinding effect. It can avoid the accumulation of waste chips inside the threaded rod frame 4 and the slide rod frame 6, prevent the waste chips from causing wear to the first threaded rod 16 and the slide rod 17, and increase the service life of the first threaded rod 16 and the slide rod 17.

[0059] Since the waste chips generated during the fine grinding of the special-shaped pressure rod arm holes are accumulated between the threaded rod frame 4 and the sliding rod frame 6, when a large amount of waste chips are accumulated between the first support block 3 and the second support block 5, the sliding frame 18 slides back and forth to facilitate the waste chip pusher plate 28 to slide on the surface of the grinder 2, so as to facilitate pushing the waste chips on the surface of the grinder 2, and to facilitate pushing the waste chips into the chip groove 29. The front side of the chip groove 29 is inclined, so as to facilitate guiding the waste chips from the chip groove 29 to the inside of the waste chip collection box 30, and collecting the waste chips through the waste chip collection box 30. Timely collection and cleaning of waste chips can avoid the accumulation of waste chips affecting the processing process, thereby improving production efficiency. Timely collection and cleaning of waste chips help to keep the working environment clean and improve the overall hygiene level of the workplace.

[0060] The arrangement of the support legs makes it easier to support the grinder 2. The support legs, as the main load-bearing structure of the grinder 2, can effectively disperse and bear the weight of the grinder 2 and its equipment to ensure the stability of the grinder 2. The arrangement of the reinforcing ribs further enhances the connection strength between the grinder 2 and the support legs to form a more stable triangular support structure, which can effectively resist external forces and vibrations and improve the stability of the overall structure. The synergistic effect of the support legs and the reinforcing ribs enables the processing table to withstand a greater load and meet various processing requirements. The reinforcing ribs can share part of the vertical load, reduce the burden on the support legs, and improve the bearing capacity of the entire structure. During the processing, the grinder 2 may be subjected to various forces, resulting in deformation or tilting. The arrangement of the support legs and the reinforcing ribs can effectively resist these forces and keep the grinder 2 flat and stable. The presence of the reinforcing ribs can also prevent the grinder 2 from sinking or tilting during long-term use, thereby extending its service life.

[0061] When the fine-grinding hole tool 26 is used for a long time, its surface will produce certain wear. When the wear reaches a certain degree, the fine-grinding hole tool 26 needs to be replaced in time. At this time, use a wrench or other tools to remove the fixing bolts on the connecting flange 25, separate the connecting flange 25 from the movable seat 24, and facilitate the disassembly of the fine-grinding hole tool 26. The decrease in processing efficiency caused by the wear of the fine-grinding hole tool 26 can be avoided, thereby improving the overall work efficiency. The wear of the fine-grinding hole tool 26 will affect the processing accuracy and surface quality of the fine-grinding hole. Timely replacement can ensure the stable quality of the special-shaped pressure rod arm. Timely replacement of the fine-grinding hole tool 26 can protect the equipment and extend its service life.

[0062] Furthermore, by providing the first pressure lever arm locating pin 11, the locating pin 12 and the second pressure lever arm locating pin 14, it is convenient to use bolts to fix the special-shaped pressure lever arm on the surfaces of the first pressure lever arm locating pin 11 and the second pressure lever arm locating pin 14. At the same time, through the interference fit between the first pressure lever arm locating pin 11 and the positioning disk 9, the first pressure lever arm locating pin 11 and the positioning disk 9 are tightly connected and not easy to fall off, thereby improving the stability of the connection. Due to the tightening force generated by the interference fit, the first pressure lever arm locating pin 11 and the positioning disk 9 can be tightly connected, thereby effectively avoiding the rotation of the first pressure lever arm locating pin 11 in the positioning disk 9. Fixing the special-shaped pressure lever arm can ensure its stable position and avoid deviations caused by movement or shaking, thereby improving the fine grinding effect. Stable fixation can prevent the special-shaped pressure lever arm from falling off or moving during the fine grinding of the hole, reduce safety hazards during operation, and improve processing accuracy and product quality.

[0063] The height of the fine-grinding hole tool 26 is adjusted by moving the movable seat 24 up and down inside the mold fixing seat 23. At the same time, the sliding frame 18 moves forward and backward, and the mold fixing seat 23 moves left and right, so that the fine-grinding hole tool 26 is easily aligned with the hole that needs to be fine-grinded on the special-shaped pressure rod arm. At the same time, the driving motor inside the grinder 2 drives the chuck 7 to rotate, so as to facilitate the fine-grinding of the hole of the special-shaped pressure rod arm. The position of the fine-grinding hole tool 26 can be quickly adjusted according to the processing requirements, which can reduce the adjustment time during the processing and improve the overall processing efficiency, thereby improving the fine-grinding effect, enhancing the versatility and flexibility of the equipment, improving the fine-grinding efficiency, and enhancing the adaptability of the equipment.

[0064] The setting of the support legs makes it easier to support the grinder 2. The support legs, as the main load-bearing structure of the grinder 2, can effectively disperse and bear the weight of the grinder 2 and its equipment to ensure the stability of the grinder 2. The setting of the reinforcement ribs further enhances the connection strength between the grinder 2 and the support legs to form a more stable triangular support structure, which effectively resists external forces and vibrations and improves the stability of the overall structure. The synergistic effect of the support legs and the reinforcement ribs enables the processing table to withstand a greater load, meet various processing requirements, improve the stability of the device, improve the carrying capacity of the device, and improve the safety of the device.

[0065] The fine grinding hole tool 26 is fixed by the movable seat 24 and the connecting flange 25, which is convenient for disassembly of the fine grinding hole tool 26, and can avoid the decrease in processing efficiency due to the wear of the fine grinding hole tool 26, thereby improving the overall work efficiency. The wear of the fine grinding hole tool 26 will affect the processing accuracy and surface quality of the fine grinding hole. Timely replacement can ensure the stable quality of the special-shaped pressure rod arm. Timely replacement of the fine grinding hole tool 26 can protect the equipment and extend its service life.

[0066] Working principle: When using the device, first place the flange 8 inside the chuck 7, place the positioning plate 9 on the front side of the flange 8, and use two pins 10 to clamp the flange 8 and the positioning plate 9 to facilitate positioning between the flange 8 and the positioning plate 9, and then place the counterweight 13 on the surface of the flange 8. Through the use of the counterweight 13, it is convenient to counterweight the upper and lower sides of the flange 8, and it is convenient to maintain balance during the rotation of the flange 8, and improve the stability of the flange 8 during rotation. Fix the flange 8 and the positioning plate 9 with multiple fixing bolts, and fix the flange 8 to the chuck 7 at the same time, which is convenient for positioning and fixing the flange 8 and the positioning plate 9, and improves the stability of the flange 8 and the positioning plate 9 during installation.

[0067] Since a groove is provided at the upper end of the positioning disk 9, it is convenient to insert the positioning pin 12 into the flange 8 and the first pressure lever arm positioning pin 11 into the positioning disk 9, and there is an interference fit between the first pressure lever arm positioning pin 11 and the positioning disk 9. The interference fit uses the elasticity of the material to expand and deform the hole on the surface of the positioning disk 9 and sleeve it on the first pressure lever arm positioning pin 11. When the hole on the surface of the positioning disk 9 is restored, a tightening force is generated on the first pressure lever arm positioning pin 11, so that the first pressure lever arm positioning pin 11 and the positioning disk 9 are tightly connected and not easy to fall off, thereby improving the stability of the connection. Due to the tightening force generated by the interference fit, the first pressure lever arm positioning pin 11 and the positioning disk 9 can be tightly connected, thereby effectively preventing the first pressure lever arm positioning pin 11 from rotating in the positioning disk 9.

[0068] Then, the special-shaped pressure lever arm that needs to be ground is sleeved on the first pressure lever arm locating pin 11, and the second pressure lever arm locating pin 14 passes through the grooves on the surface of the special-shaped pressure lever arm and the locating plate 9, and the second pressure lever arm locating pin 14 is inserted into the interior of the locating pin 12, so as to facilitate the positioning of the second pressure lever arm locating pin 14 and the first pressure lever arm locating pin 11, and to facilitate the fixing of the special-shaped pressure lever arm, and the special-shaped pressure lever arm is fixed to the surface of the first pressure lever arm locating pin 11 with a screw 31, and then the second pressure lever arm locating pin 14 is pulled outward to make the second pressure lever arm The arm locating pin 14 is separated from the special-shaped pressure lever arm and 12. Due to the cooperation between the second pressure lever arm locating pin 14 and the locating pin 12, the hole of the special-shaped pressure lever arm is exactly in a straight line with the locating pin 12, that is, the hole of the special-shaped pressure lever arm that needs to be fine-ground is located at the center of the flange 8. Fixing the special-shaped pressure lever arm can ensure its stable position and avoid deviation caused by movement or shaking, thereby improving the fine grinding effect. Stable fixation can prevent the special-shaped pressure lever arm from falling off or moving during the fine grinding process, reducing safety hazards during operation.

[0069] Start the first drive motor 15 to drive the first threaded rod 16 to rotate inside the threaded rod frame 4, the first threaded rod 16 drives the sliding frame 18 to slide inside the threaded rod frame 4, and the sliding frame 18 slides on the surface of the sliding rod 17 and the sliding rod frame 6, start the second drive motor 20 to drive the second threaded rod 21 to rotate, the second threaded rod 21 drives the slider 22 to slide inside the movable frame 19, and the slider 22 drives the mold fixing seat 23 to move. Since the sliding frame 18 is in an "M" shape as a whole, that is, the sliding frame 18 is high on both sides and low in the middle, it is convenient to lower the center of gravity of the sliding frame, and to maintain stability during the movement of the sliding frame 18, ensuring that the movable frame 19 and the mold fixing seat 23 can move smoothly along the predetermined path, which can not only change the movement direction of the movable frame 19 and the mold fixing seat 23, but also provide stable support to ensure the smoothness and safety of the movement of the movable frame 19 and the mold fixing seat 23.

[0070] The mold fixing seat 23 drives the movable seat 24, the connecting flange 25 and the fine grinding hole tool 26 to move. Through the forward and backward movement of the sliding frame 18 and the left and right movement of the mold fixing seat 23, it is convenient to drive the fine grinding hole tool 26 to move in the direction of the special-shaped pressure rod arm. Through the setting of the connecting flange 25 and the movable seat 24, and the fixing of the movable seat 24 and the connecting flange 25 by fixing bolts, it is convenient to limit the fine grinding hole tool 26. Starting the electric telescopic rod 27 drives the movable seat 24 to slide inside the mold fixing seat 23, so as to adjust the height of the fine grinding hole tool 26 according to the height of the hole of the special-shaped pressure rod arm, so that the fine grinding hole tool 26 can contact the inner wall of the hole of the special-shaped pressure rod arm during the movement.

[0071] At the same time, the driving motor on the inner wall of the grinder 2 is started to drive the chuck 7 to rotate, and the chuck 7 drives the flange 8, the positioning plate 9 and the first pressure rod arm positioning pin 11 to rotate, thereby driving the special-shaped pressure rod arm on the surface of the first pressure rod arm positioning pin 11 to rotate, so as to facilitate the fine grinding of the hole of the special-shaped pressure rod arm.

[0072] When the fine-grinding hole tool 26 is used to fine-grind the hole of the special-shaped pressure rod arm, some waste chips will be ground out on the inner wall of the hole of the special-shaped pressure rod arm. After the waste chips are ground out, the waste chips may splash during the rotation of the chuck 7. The arrangement of the first support block 3, the threaded rod frame 4, the second support block 5 and the slide rod frame 6 facilitates the blocking of the waste chips, and facilitates the blocking of the waste chips between the threaded rod frame 4 and the slide rod frame 6 during the fine-grinding hole processing, thereby keeping the working environment clean and tidy. At the same time, it also helps to protect the safety of the operator and prevent accidental injuries caused by waste chips. The openings of the threaded rod frame 4 and the slide rod frame 6 are arranged toward the outside and downward of the grinder 2, which facilitates operation and maintenance, effectively removes chips, improves safety and optimizes the grinding effect. It can avoid the accumulation of waste chips inside the threaded rod frame 4 and the slide rod frame 6, prevent the waste chips from causing wear to the first threaded rod 16 and the slide rod 17, and increase the service life of the first threaded rod 16 and the slide rod 17.

[0073] Since the waste chips generated during the fine grinding of the special-shaped pressure rod arm holes are accumulated between the threaded rod frame 4 and the sliding rod frame 6, when a large amount of waste chips are accumulated between the first support block 3 and the second support block 5, the sliding frame 18 slides back and forth to facilitate the waste chip pusher plate 28 to slide on the surface of the grinder 2, so as to facilitate pushing the waste chips on the surface of the grinder 2, and to facilitate pushing the waste chips into the chip groove 29. The front side of the chip groove 29 is inclined, so as to facilitate guiding the waste chips from the chip groove 29 to the inside of the waste chip collection box 30, and collecting the waste chips through the waste chip collection box 30. Timely collection and cleaning of waste chips can avoid the accumulation of waste chips affecting the processing process, thereby improving production efficiency. Timely collection and cleaning of waste chips help to keep the working environment clean and improve the overall hygiene level of the workplace.

[0074] The arrangement of the support legs makes it easier to support the grinder 2. The support legs, as the main load-bearing structure of the grinder 2, can effectively disperse and bear the weight of the grinder 2 and its equipment to ensure the stability of the grinder 2. The arrangement of the reinforcing ribs further enhances the connection strength between the grinder 2 and the support legs to form a more stable triangular support structure, which can effectively resist external forces and vibrations and improve the stability of the overall structure. The synergistic effect of the support legs and the reinforcing ribs enables the processing table to withstand a greater load and meet various processing requirements. The reinforcing ribs can share part of the vertical load, reduce the burden on the support legs, and improve the bearing capacity of the entire structure. During the processing, the grinder 2 may be subjected to various forces, resulting in deformation or tilting. The arrangement of the support legs and the reinforcing ribs can effectively resist these forces and keep the grinder 2 flat and stable. The presence of the reinforcing ribs can also prevent the grinder 2 from sinking or tilting during long-term use, thereby extending its service life.

[0075] When the fine-grinding hole tool 26 is used for a long time, its surface will produce certain wear. When the wear reaches a certain degree, the fine-grinding hole tool 26 needs to be replaced in time. At this time, use a wrench or other tools to remove the fixing bolts on the connecting flange 25, separate the connecting flange 25 from the movable seat 24, and facilitate the disassembly of the fine-grinding hole tool 26. The decrease in processing efficiency caused by the wear of the fine-grinding hole tool 26 can be avoided, thereby improving the overall work efficiency. The wear of the fine-grinding hole tool 26 will affect the processing accuracy and surface quality of the fine-grinding hole. Timely replacement can ensure the stable quality of the special-shaped pressure rod arm. Timely replacement of the fine-grinding hole tool 26 can protect the equipment and extend its service life.
