The slide plates 101 are rotatably connected with rotating blocks 107, and the rotating blocks 107 and The rotating shaft 5 is spline-connected. When the rotating shaft 5 rotates, it will drive the rotating block 107 to rotate, but will not drive the sliding plate 101 to rotate; the rotating block 107 and the adjacent sliding block 100 are both rotatably connected with the hinge rod 102, and the lifting plate 81 is provided with a long groove for the hinge rod 102 to pass through and move; the grinding block control mechanism also includes an upper arc plate 104 and a lower arc plate 105, and a feed port 120 is provided on the side of the outer cylinder 1. The upper arc plate 104 and the lower arc plate 105 are fixedly connected inside the outer cylinder 1, such as Fig.10 As shown, the positions of the upper arc plate 104, the lower arc plate 105 and the feed port 120 are staggered, and the left end of the upper arc plate 104 and the right end of the lower arc plate 105 are bent upward to form an inclined surface 106; when the slide plate 101 rotates around the rotating column 2, the six slide plates 101 on the upper side will contact the inclined surface 106 of the upper arc plate 104, and the six slide plates 101 on the lower side will contact the inclined surface 106 of the lower arc plate 105, so as to squeeze the slide plate 101 to move downward through the inclined surface 106.

[0037] Initially, refer to Figure 3 There are six groups of upper grinding discs 7 and lower grinding discs 6, each group of upper grinding discs 7 and lower grinding discs 6 is a station, and the station at the rightmost position at the feed port 120 is called station one. Figure 3 The clockwise direction is station two, station three, station four, station five and station six; the movable rod of the electric cylinder of station one is Figure 4 In the extended state shown, the lifting frame 4 and the upper grinding disk 7 of the station one are in the ascending state, and the upper grinding disk 7 and the lower grinding disk 6 of the station one are separated, so that the seal 70 to be ground can be placed at the center of the lower grinding disk 6 from the feed port 120; while the movable rods of the electric cylinders of other stations are in the shortened state, and the upper grinding disk 7 and the lower grinding disk 6 of other stations are close to each other, so that the inner clamping block 9 and the electric inner grinding column 11 can extend into the interior of the seal 70, and the upper grinding disk 7 and the lower grinding disk 6 of other stations can contact the top and bottom surfaces of the seal 70 respectively.

[0038] The method of switching the workstations is as follows: control the servo motor to drive the rotating column 2 to rotate intermittently clockwise, and the rotating column 2 will drive the fixed frame 3, the lifting frame 4, the rotating shaft 5, the lower grinding disc 6, the upper grinding disc 7, the outer clamping block 8, the inner clamping block 9, the electric outer grinding column 10 and the electric inner grinding column 11 to rotate intermittently clockwise around the rotating column 2 as a whole, and each rotation angle is 60 degrees, that is, the position of a workstation is switched.

[0039] The control method of the outer clamp block 8 and the inner clamp block 9 is as follows: Figure 7 , control the electric push rod 1 83 on the fixed frame 3 to drive the push block 84 thereon to move downward. The shape of the push block 84 is shown in the figure. The push block 84 contacts the top and bottom surfaces of the lifting plate 81. The downward moving push block 84 will push the lifting plate 81 to move downward, and the lifting plate 81 will move away from the lower grinding plate 6. Through the transmission of the hinge rod 1 82, the two outer clamping blocks 8 can be brought close to each other along the straight groove 2 72, so that the two outer clamping blocks 8 are in contact with the outer surface of the sealing member 70, thereby clamping the sealing member 70; conversely, control the electric push rod 1 83 on the fixed frame 3 to drive The push block 84 thereon moves upward, and the push block 84 pushes the lifting plate 81 to rise, and the two outer clamping blocks 8 are moved away from each other through the transmission of the hinged rod 82, and the two outer clamping blocks 8 are separated from the outer surface of the sealing member 70; similarly, the electric push rod 83 on the lifting frame 4 is controlled to drive the push block 84 thereon to rise or fall, which can respectively make the two inner clamping blocks 9 approach each other and move away from each other, and the two inner clamping blocks 9 are separated from the inner surface of the sealing member 70 when they are approaching each other, and they can contact the inner surface of the sealing member 70 to clamp the sealing member 70 when the two inner clamping blocks 9 move away from each other.

[0040] When it is necessary to grind the seal 70, first place the seal 70 at the center of the lower grinding disk 6 of the station one from the feed port 120, control the movable rod of the electric cylinder of the station one to shorten, and drive the corresponding lifting frame 4, rotating shaft 5, upper grinding disk 7, lifting disk 81, slide plate 101, inner clamp block 9 and electric inner grinding column 11 to move downward as a whole, so that the inner clamp block 9 and the electric inner grinding column 11 extend into the seal 70. At this time, the inner clamp block 9, outer clamp block 8, electric inner grinding column 11 and electric outer grinding column 10 of the station one are all in a state of separation from the surface of the seal 70; then the "control method of the outer clamp block 8 and the inner clamp block 9" is used to make the two inner clamp blocks 9 move away from each other, and the two inner clamp blocks 9 clamp the seal 70.

[0041] When the workstation is switched for the first time, the lower slide plate 101 will contact the inclined surface 106 at the right end of the lower arc plate 105 during the switching process. The lower arc plate 105 squeezes the slide plate 101, causing the lower slide plate 101 to rotate and move downward along the inclined surface 106. The corresponding spring 103 is compressed, and the corresponding two sliders 100 are driven by the hinge rod 82 to approach each other along the straight groove 71, driving the two electric outer grinding columns 10 to approach each other and contact the outer surface of the seal 70; after the workstation switching is completed, the drive motor located above the second workstation is controlled to drive the rotating shaft 5 thereon to rotate, driving the upper grinding disk 7 of the second workstation, the upper lifting disk 81, the inner clamping block 9, the upper slide plate 101, the upper rotating block 107, the electric inner grinding column 11 and the seal 70 clamped by the inner clamping block 9 to rotate around the rotating shaft 5. Since the lower grinding disk 6 contacts the bottom of the seal 70, the lower grinding disk 6 can grind the bottom surface of the seal 70.

[0042] The second time the workstation is switched, the drive motor located above the workstation three is controlled to continue driving the rotating shaft 5 thereon to rotate, and the upper grinding disc 7, the inner clamping block 9, the electric inner grinding column 11 of the workstation three and the seal 70 clamped by the inner clamping block 9 continue to rotate around the rotating shaft 5. At the same time, the electric outer grinding column 10 of the workstation three is controlled to rotate, and the electric outer grinding column 10 grinds the outer surface of the seal 70.

[0043] When the workstation is switched for the third time, the slide plate 101 below the workstation four will separate from the lower arc plate 105, and the slide plate 101 will move upward and reset under the action of the spring 103, and the two sliders 100 will be driven away from each other by the hinge rod 102, and the two electric outer grinding columns 10 of the workstation four will be separated from the seal 70; then the "control method of the outer clamping block 8 and the inner clamping block 9" will be used to make the two inner clamping blocks 9 of the workstation four approach each other to loosen the seal 70, and make the two outer clamping blocks 8 approach each other and contact with the outer surface of the seal 70, and the two outer clamping blocks 8 will clamp the seal 70.

[0044] The fourth station switching process, during which the upper slide 101 will contact the inclined surface 106 at the left end of the upper arc plate 104, the upper arc plate 104 squeezes the slide 101, causing the upper slide 101 to rotate while moving downward along the inclined surface 106, and the corresponding spring 103 is stretched. Similarly, the two corresponding sliders 100 are driven away from each other through the transmission of the hinge rod 1 82, driving the two electric inner grinding columns 11 to move away from each other and contact the inner surface of the seal 70; after the station switching is completed, the drive motor located below the station five is controlled to drive the rotating shaft 5 thereon to rotate, driving the lower grinding disk 6 of the station five, the lower lifting disk 81, the outer clamping block 8, the lower slide 101 and the seal 70 clamped by the outer clamping block 8 to rotate around the rotating shaft 5. Since the upper grinding disk 7 is in contact with the top of the seal 70, the upper grinding disk 7 can grind the top surface of the seal 70.

[0045] The fifth workstation switch controls the drive motor located below workstation six to continue driving the rotating shaft 5 thereon to rotate. The lower grinding disc 6, the outer clamping block 8 and the seal 70 clamped by the outer clamping block 8 of workstation six continue to rotate around the rotating shaft 5. At the same time, the electric inner grinding column 11 of workstation six is ​​controlled to rotate, and the electric inner grinding column 11 grinds the inner surface of the seal 70.

[0046] At the sixth workstation switch, the ground seal 70 moves back to the position of workstation one. At this time, the electric cylinder controlling workstation one drives the lifting frame 4 to rise and reset, driving the upper grinding disk 7 of workstation one to rise and reset, and controlling the two outer clamping blocks 8 of workstation one to move away from each other to loosen the seal 70, so that the ground seal 70 can be removed.

[0047] In this reciprocating operation, the bottom surface, top surface, outer surface and inner surface of the seal 70 can be ground respectively through the lower grinding disc 6, the upper grinding disc 7, the electric outer grinding column 10 and the electric inner grinding column 11. The grinding is complete and the grinding effect is good, thereby ensuring the sealing of the seal 70. Moreover, through the setting of multiple workstations, multiple seals 70 can be ground at the same time, and the loading and grinding work are carried out simultaneously. The grinding process is automated and the working efficiency is high.

By adjusting the position of the baffle 136, it can adapt to seals 70 of different heights in the placement frame 135, so that only one seal 70 in the placement frame 135 will not be blocked by the baffle 136. Two bolts are threadedly connected to the baffle 136. When the bolts are tightened, the bolts are in close contact with the side of the placement frame 135, thereby fixing the position of the baffle 136.

[0050] refer to Figure 1 and Fig.11 The grinding device for lifting mechanical seals further comprises a collecting frame 141 and a filter frame 142 . The collecting frame 141 is fixedly connected to the front of the fixing plate 121 , and the filter frame 142 is disposed on the collecting frame 141 .

[0051] refer to Figure 1 The grinding device for lifting machinery seals also includes a guide hopper 152. A plurality of water inlets 151 are provided on the side of the outer cylinder 1. The bottom of the outer cylinder 1 is connected to the guide hopper 152. A pipeline is connected between the bottom of the collecting frame 141 and the guide hopper 152. Cooling water is introduced through the water inlet 151 to facilitate cooling of the seal 70 being ground. The sewage generated after cooling flows to the guide hopper 152, and the water in the collecting frame 141 also flows to the guide hopper 152 through the pipeline, thereby facilitating centralized treatment of the sewage.

In this process, the lower rotating plate 1242 first moves with the lower long plate 1243 and the lower short plate 1244. The upper plate 1244 separates, and then the rear end of the upper rotating plate 1241 contacts the right end of the upper long plate 1245. The rear end of the upper rotating plate 1241 is blocked, and the upper rotating plate 1241 moving left will rotate 90 degrees clockwise and drive the lower rotating plate 1242, the electric push rod 124, the connecting frame 125, the electric clamp 126 and the grasped seal 70 to rotate 90 degrees clockwise. The upper short plate 1246 will not block the rotating upper rotating plate 1241, and the upper rotating plate 1241 continues to move left, and the upper rotating plate 1241 enters between the upper long plate 1245 and the upper short plate 1246 again. For details, refer to Fig.14The upper rotating plate 1241 is limited by the upper long plate 1245 and the upper short plate 1246, so that the upper rotating plate 1241, the lower rotating plate 1242, the electric push rod 124, the connecting frame 125, the electric clamp 126 and the grasped seal 70 maintain the position after rotation, the upper rotating plate 1241, the lower rotating plate 1242, the electric push rod 124, the connecting frame 125, the electric clamp 126 and the grasped seal 70 continue to move to the left, and the electric clamp 126 and the grasped seal 70 enter the outer cylinder 1 from the feed port 120. When the seal 70 is located directly above the lower grinding disk 6 of the workstation one, the seal 70 can be placed on the lower grinding disk 6 by controlling the electric push rod 124 and the electric clamp 126.

[0054] The electric slide rail 122 is controlled to drive the translation block 123 to translate to the right, so that the electric clamp 126 moves to the right and temporarily leaves the inner part of the outer cylinder 1. After the workstation is switched, the grinding seal 70 moves to the workstation 1, and the electric slide rail 122 is controlled to drive the translation block 123 and the electric clamp 126 to move to the left, and the electric clamp 126 enters the outer cylinder 1 again, and the electric clamp 126 grabs the grinding seal 70 on the workstation 1; then the electric slide rail 122 is controlled to drive the translation block 123 and the electric clamp 126 to move to the left, and the electric clamp 126 enters the outer cylinder 1 again, and the electric clamp 126 grabs the grinding seal 70 on the workstation 1; 122 causes the translation block 123, the upper rotating plate 1241, the lower rotating plate 1242, the electric push rod 124, the connecting frame 125, the electric clamp 126 and the captured seal 70 to move to the right. During this process, the upper rotating plate 1241 is first separated from the upper long plate 1245 and the upper short plate 1246, and then the rear end of the lower rotating plate 1242 contacts the left end of the lower long plate 1243, and the rear end of the lower rotating plate 1242 is blocked, and the lower rotating plate 1242 moves to the right. The lower rotating plate 1242 is moved by the electric clamp 126 and the lower rotating plate 1244 is moved by the electric clamp 126, and the upper rotating plate 1242 is moved by the electric clamp 126.
