[0003] Before grinding a metal workpiece, the existing device usually fixes the metal workpiece in the area to be processed by a fixed structure and then grinds it. However, when impurities on the surface of the metal workpiece are distributed at different heights, it is necessary to adjust the height between the metal workpiece and the grinding sheet when processing the metal workpiece, so that the contact distance between the metal workpiece and the grinding sheet changes, thereby grinding the metal workpiece with different intensities. However, when adjusting, the existing device usually releases the metal workpiece and adjusts the height of the fixed structure to change the height of the metal workpiece. However, in this process, due to the different heights of impurities on the metal workpiece, frequent adjustments are required to grind it, which increases the difficulty of adjusting the height of the metal workpiece. In view of this, we propose a fine grinding device for servo equipment production. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the fine grinding device used for the production of servo equipment, through the coordination setting between the connecting column, the connecting column, the connecting block and the positioning frame and other structures, the weight of the metal workpiece itself causes the supporting plate and the connecting block and other structures to move to the side away from the positioning frame. During the movement of the connecting block, the first swing rod and the rectangular block drive the positioning frame to fix the metal workpiece to be processed placed inside the sliding frame. Then, when the height of the metal workpiece needs to be adjusted, the cooperation between the sliding plate and the connecting member drives the second swing rod to swing. When the second swing rod swings, the pin shaft drives the first adjusting plate to swing. At this time, the first adjusting plate squeezes the metal workpiece above the sliding frame and the supporting plate, causing the metal workpiece to move to the side away from the supporting plate, thereby adjusting the distance between the metal workpiece and the grinding sheet, so that the grinding sheet can grind the surface of the metal workpiece with different intensities.

[0023] 2. In the fine grinding device used for servo equipment production, during the process of adjusting the height of the metal workpiece through the adjustment structure, the sliding plate drives the first rack to move, and when the first rack moves, the connecting column is driven to rotate through the gear, and the positioning structure and the processing table are limited by the rotation of the connecting column to avoid that when the metal workpiece is not in contact with the support plate, the positioning frame no longer fixes the metal workpiece. At the same time, when the first rack moves, the first adjustment plate and the second adjustment plate away from the servo cylinder side are driven to swing through the cooperation between the limit block, the gear and the second rack, so that the metal workpiece above the support plate is smoothly raised and lowered.

[0035] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The metal products industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers, stainless steel and similar daily metal products, etc. With the progress of society and the development of science and technology, metal products are being used more and more widely in industry, agriculture and all areas of people's lives, creating more and more value for society.

[0037] See also Figure 1-Figure 9 As shown, this embodiment provides a fine grinding device for servo equipment production, including a processing table 1, a positioning structure 2 for fixing a metal workpiece before grinding is arranged on the top of the processing table 1, an adjustment structure 3 for grinding the metal workpiece to different degrees is arranged on the top of the processing table 1, and a fixing structure 4 is arranged at the bottom of the processing table 1;

[0038] After the metal workpiece is placed on the positioning structure 2, the weight of the metal workpiece drives the positioning structure 2 and the adjusting structure 3 to move in the direction close to the metal workpiece. At this time, the adjusting structure 3 is started to lift the metal workpiece without contact with the positioning structure 2, and at the same time drives the fixed structure 4 to slide in the direction close to the positioning structure 2. When the fixed structure 4 moves, it drives the positioning structure 2 to rotate.

[0039] The present invention takes into account that in the existing device, before grinding the metal workpiece, the metal workpiece is usually fixed in the area to be processed by a fixed structure and then ground. However, when the impurities on the surface of the metal workpiece are distributed at different heights, it is necessary to adjust the height between the metal workpiece and the grinding sheet when processing the metal workpiece, so that the contact distance between the metal workpiece and the grinding sheet changes, thereby grinding the metal workpiece with different intensities. However, when adjusting, the existing device usually releases the metal workpiece and adjusts the height of the fixed structure to change the height of the metal workpiece. However, in this process, due to the different heights of the impurities on the metal workpiece, frequent adjustments are required to grind it. The present invention uses the sliding plate 31 and the connecting member 32 to adjust the height of the fixed structure. The cooperation between them drives the second swing rod 33 to swing. When the second swing rod 33 swings, it drives the first adjustment plate 34 to swing through the pin shaft. At this time, the first adjustment plate 34 squeezes the sliding frame 36 and the metal workpiece above the support plate 21, so that the metal workpiece moves to the side away from the support plate 21, thereby adjusting the distance between the metal workpiece and the grinding sheet 13, so that the grinding sheet 13 can grind the surface of the metal workpiece with different intensities. The sliding plate 31 drives the first rack 41 to move. When the first rack 41 moves, it drives the connecting column 22 to rotate through the gear 42. The rotation of the connecting column 22 limits the positioning structure 2 and the processing table 1 to avoid that when the metal workpiece is not in contact with the support plate 21, the positioning frame 27 no longer fixes the metal workpiece.

[0040] In the above embodiments, the following specific structures need to be disclosed in detail:

[0041] A controller 11 is installed on the top of the processing table 1. A grinding structure 12 is arranged on the top of the processing table 1. A driving component is installed on one side of the grinding structure 12. A grinding sheet 13 is fixedly connected to the output shaft end of the driving component. A cleaning structure 14 is installed on one side of the grinding structure 12. The cleaning structure 14 is located on one side of the grinding sheet 13. A servo cylinder 15 is installed on the bottom of the processing table 1. The controller 11 is electrically connected to the servo cylinder 15.

[0042] A limiting groove is provided on the top of the processing table 1 , a guide groove is provided on the top of the processing table 1 for discharging the cleaning liquid used by the cleaning structure 14 , and a groove is provided on the top of the processing table 1 .

[0043] refer to Figure 1 As shown, considering that the surface of the metal workpiece needs to be cleaned and cooled when it is polished, during the use of the present invention, the driving component drives the polishing plate 13 to polish the metal workpiece fixed by the positioning structure 2, and the polishing plate 13 cleans the surface of the processed metal workpiece through the output shaft end of the cleaning structure 14 during the polishing process.

[0044] The positioning structure 2 includes a support plate 21 located on the top of the processing table 1, and a connecting column 22 rotatably connected to the processing table 1 is slidably connected to the bottom of the support plate 21;

[0045] The connection column 22 is fixedly connected to the outer wall of the support plate 21 with a limit block 23 . The distance between the limit block 23 and the support plate 21 is slightly larger than the thickness of the processing table 1 . The limit block 23 and the limit groove opened on the top of the processing table 1 are adapted to each other.

[0046] The connecting column 22 is rotatably connected to the outer wall of the supporting plate 21, and a spring is arranged between the bottom of the connecting block 24 and the processing table 1 to elastically connect the two. The side of the connecting block 24 away from the supporting plate 21 is rotatably connected to the first swing arm 25, and the side of the first swing arm 25 away from the connecting block 24 is rotatably connected to the rectangular block 26. The rectangular block 26 and the top of the processing table 1 are provided with a groove for sliding connection. The top of the rectangular block 26 is fixedly connected to a positioning frame 27, and the depth of the positioning frame 27 away from the connecting column 22 is slightly greater than the width of the second adjustment plate 35.

[0047] Considering that the metal workpiece can be clamped stably before processing, the limit block 23 , the connecting block 24 , the first swing arm 25 , the rectangular block 26 and the positioning frame 27 are symmetrically arranged along the vertical center line of the support plate 21 .

[0048] refer to Figure 2 and Figure 3Before grinding the metal workpiece, the metal workpiece is placed inside the two sliding racks 36. Since the sliding rack 36 is slidably connected to the positioning rack 27 through the elastic column, after the metal workpiece is placed inside the sliding rack 36, the metal workpiece presses the sliding rack 36 to slide toward the side close to the support plate 21 according to its own weight. During the movement of the metal workpiece, the support plate 21 is simultaneously pressed, so that the support plate 21 slides toward the side away from the positioning rack 27. At this time, the support plate 21 drives the limit block 23 and the connecting block 24 to move toward the side away from the positioning rack 27 through the connecting column 22;

[0049] refer to Figure 3 When the connecting block 24 moves, it drives the first swing rod 25 to swing toward the side close to the support plate 21. When the first swing rod 25 swings, it drives the rectangular block 26 connected to it to slide in the groove opened on the top of the processing table 1. When the rectangular block 26 slides, it drives the positioning frame 27 to slide toward the side close to the support plate 21.

[0050] refer to Figure 4 After the positioning frame 27 clamps the metal workpiece through the sliding frame 36 slidably connected thereto, the limiting block 23 is now at the bottom of the processing table 1 .

[0051] The adjustment structure 3 includes a sliding plate 31 fixedly connected to the output shaft end of the servo cylinder 15, and two connecting members 32 are fixedly connected to one side of the sliding plate 31 away from the connecting column 22. The two connecting members 32 are located on both sides of the sliding plate 31, and a second swing rod 33 is arranged outside the connecting member 32 away from the sliding plate 31;

[0052] Guide grooves are formed on both sides of the second swing rod 33, and convex columns are fitted inside the guide grooves, and the outer wall of the convex column is fixedly connected to the side of the connecting member 32 away from the sliding plate 31;

[0053] A first adjustment plate 34 and a second adjustment plate 35 are fixedly connected to one side of the second swing rod 33 away from the connecting member 32 via a pin shaft, and a sliding frame 36 is arranged on the top of the second adjustment plate 35 .

[0054] refer to Figure 6 , considering that when the positioning frame 27 moves toward the side close to the connecting column 22, the inside of the positioning frame 27 squeezes the side of the second adjustment plate 35 away from the first adjustment plate 34, the depth of the positioning frame 27 away from the connecting column 22 is slightly greater than the width of the second adjustment plate 35. After the sliding frame 36 clamps the metal workpiece, the bottom of the sliding frame 36 is above the second adjustment plate 35, so that when the second adjustment plate 35 swings toward the side away from the processing table 1, the second adjustment plate 35 supports the sliding frame 36, thereby adjusting the height of the metal workpiece after being fixed inside the sliding frame 36.

[0055] The second adjustment plate 35 is located on one side of the positioning frame 27 close to the support plate 21 , the first adjustment plate 34 is located on both sides of the support plate 21 , and the first adjustment plate 34 is located in the middle of the two positioning frames 27 , and the sliding frame 36 is slidably connected to the positioning frame 27 through elastic columns.

[0056] refer to Figure 5 and Figure 6 After the metal workpiece to be polished is clamped by the positioning structure 2, the staff controls the controller 11 to start the servo cylinder 15, so that the output shaft end of the servo cylinder 15 drives the sliding plate 31 to move toward the side close to the connecting column 22. When the sliding plate 31 moves, it drives the connecting member 32 to slide toward the side close to the connecting column 22. When the connecting member 32 slides, it drives the convex column fixedly connected inside it to slide in the guide grooves provided on both sides of the second swing rod 33, so that the convex column squeezes the second swing rod 33, so that it drives the first adjustment plate 34 and the second adjustment plate 35 fixedly connected to it by the pin shaft to swing toward the side away from the processing table 1.

[0057] refer to Figure 8 As shown, when the first adjustment plate 34 and the second adjustment plate 35 swing toward the side away from the processing table 1, the second adjustment plate 35 squeezes the sliding frame 36 to slide toward the side away from the support plate 21. At the same time, after the positioning structure 2 clamps the metal workpiece to be polished, the bottom of the metal workpiece is above the first adjustment plate 34. When the first adjustment plate 34 swings, it squeezes the bottom of the second adjustment plate 35 to move toward the side away from the processing table 1.

[0058] The first adjustment plate 34 and the second adjustment plate 35 are used to move the metal workpiece to the side away from the support plate 21. At this time, the support plate 21 will no longer contact the metal workpiece, thereby preventing the heat generated by the metal workpiece being polished by the polishing sheet 13 from being transferred to the surface of the support plate 21 and causing damage to the support plate 21.

[0059] refer to Figure 8 When the metal workpiece moves toward the side away from the support plate 21 through the sliding frame 36, the sliding frame 36 gradually reduces the distance between the metal workpiece and the grinding sheet 13. At this time, the staff observes the distance between the metal workpiece and the grinding sheet 13. When the metal workpiece and the grinding sheet 13 are at a suitable distance, the staff controls the controller 11 to close the servo cylinder 15. Due to the different contact distances between the metal workpiece and the cleaning structure 14, the pressure exerted by the cleaning structure 14 on the metal workpiece is different, and the grinding intensity of the cleaning structure 14 on the metal workpiece will also change. Therefore, by adjusting the distance between the cleaning structure 14 and the metal workpiece, the metal workpiece can be ground to different degrees.

[0060] The fixing structure 4 includes a first rack 41 fixedly connected to the side of the sliding plate 31 away from the servo cylinder 15 , and a gear 42 is provided on the side of the first rack 41 close to the connecting column 22 , and the gear 42 is fixedly connected to the outer wall of the connecting column 22 .

[0061] When the servo cylinder 15 drives the second adjustment plate 35 and the first adjustment plate 34 to swing toward the side away from the support plate 21 through the cooperation among the structures such as the sliding plate 31, the second swing rod 33 and the connecting member 32, the sliding plate 31 synchronously drives the first rack 41 fixedly connected thereto to move toward the side close to the support plate 21, and at this time, the support plate 21 drives the connecting column 22 to be in a direction away from the positioning frame 27 due to the weight of the metal workpiece, and at this time, the gear 42 fixedly connected to the outer wall of the connecting column 22 is on the same horizontal line as the first rack 41, and at this time, when the first rack 41 moves toward the side close to the support plate 21, it drives the connecting column 22 to rotate through the gear 42;

[0062] Because the connecting column 22 is rotatably connected to the support plate 21 and the connecting block 24, when the connecting column 22 rotates, the support plate 21 and the connecting block 24 will not rotate synchronously, so as to avoid the support plate 21 and the connecting block 24 being unable to clamp the metal workpiece when they rotate;

[0063] refer to Fig. 9 , considering that the positioning structure 2 can be locked when the adjustment structure 3 moves, when the gear 42 drives the connecting column 22 to rotate, the connecting column 22 drives the limit block 23 fixedly connected thereto to rotate, and the limit block 23 is now in the space between the first rack 41 and the processing table 1. After the limit block 23 rotates, the limit block 23 will be separated from the limit groove opened on the top of the processing table 1, so as to avoid that when the sliding frame 36 drives the metal workpiece to move away from the support plate 21, the connecting block 24 will drive the first swing rod 25 and the rectangular block 26 to move away from the support plate 21 through the spring between the processing table 1, so as to avoid that the distance between the positioning frame 27 and the metal workpiece changes, resulting in the metal workpiece being unable to be fixed;

[0064] The sliding plate 31 , the connecting member 32 , the second swing rod 33 , the first adjusting plate 34 and the second adjusting plate 35 are symmetrically arranged along the center line of the connecting column 22 .

[0065] A side of the gear 42 away from the first rack 41 is meshedly connected with the second rack 43 , and a side of the second rack 43 away from the first rack 41 is fixedly connected with another sliding plate 31 .

[0066] refer to Fig. 9, considering that the metal workpiece can be lifted and lowered smoothly when the distance between the metal workpiece and the cleaning structure 14 is adjusted, when the gear 42 rotates, it drives the second rack 43 to move toward the side close to the servo cylinder 15. When the second rack 43 moves, it synchronously drives the sliding plate 31 away from the side of the servo cylinder 15 and the second swing rod 33 close to the side of the servo cylinder 15 to move synchronously. At this time, according to the description of the sliding plate 31 close to the servo cylinder 15, the first adjustment plate 34 and the second adjustment plate 35 away from the side of the servo cylinder 15 will also move synchronously with the first adjustment plate 34 and the second adjustment plate 35 close to the side of the servo cylinder 15, so that the metal workpiece can be lifted and lowered smoothly.

[0067] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
