Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] like Figure 1-7As shown, an automatic grinding device for partitions includes a crossbeam 1. A guide cylinder 2 is fixed to one side of the bottom end of the crossbeam 1. A connecting structure 3 is slidably disposed inside the guide cylinder 2. The connecting structure 3 can reciprocate up and down along the axial direction of the guide cylinder 2. The bottom end of the connecting structure 3 extends to the bottom of the guide cylinder 2. A lead screw 15 is disposed inside the guide cylinder 2. The bottom of the lead screw 15 passes through the top end of the connecting structure 3 and extends into the connecting structure 3. The upper part of the lead screw 15 passes through the bottom end of the crossbeam 1 and extends into the inner side of the crossbeam 1. A second motor 13 is fixed to the top end of the crossbeam 1. The output end of the second motor 13 passes through the top end of the crossbeam 1 and extends into the inner side of the crossbeam 1. A transmission assembly 14 is connected between the output end of the second motor 13 and the top end of the lead screw 15. The transmission assembly 14 consists of two first synchronous pulleys and a first synchronous belt. The two first synchronous pulleys are fixed to the output end of the second motor 13 and the top end of the lead screw 15, respectively. The first synchronous belt drives the two first synchronous pulleys. The second motor 13 drives the first synchronous pulley connected to it to rotate. The first synchronous belt drives the other first synchronous pulley to rotate, causing the lead screw 15 to rotate. The lead screw 15 rotates in conjunction with the crossbeam 1. As the lead screw 15 rotates, it drives the connecting structure 3 to move up and down reciprocally inside the guide cylinder 2.

[0028] A mounting structure 4 is rotatably sleeved on the lower part of the connecting structure 3. A seat 5 is embedded at the bottom end of the mounting structure 4 and is fixed to the bottom end of the connecting structure 3 by bolts. A ball bearing 51 is embedded at the top of the seat bearing 5 and rolls with the mounting structure 4. A first motor 6 is installed on one side of the connecting structure 3. A drive gear 61 is fixed at the output end of the first motor 6 and is connected to the mounting structure 4 for transmission. The first motor 6 drives the drive gear 61 to rotate, causing the mounting structure 4 to rotate on the connecting structure 3. Through the ball bearing 51 between the seat bearing 5 and the mounting structure 4, the mounting structure 4 will not fall off the connecting structure 3 during the process of rotating relative to the seat bearing 5.

[0029] Two clamping cylinders 9 are hinged to the middle of the outer surface of the seat bucket 5, and two clamping frames 8 are hinged to the lower part of the outer surface of the seat bucket 5. The output ends of the two clamping cylinders 9 are respectively hinged to the two clamping frames 8. Under the action of the two clamping cylinders 9, the two clamping frames 8 can perform closing or opening actions to clamp the partition and release it after clamping. After the partition is clamped by the two clamping frames 8, it can perform up and down reciprocating motion in cooperation with the No. 2 motor 13 and the lead screw 15.

[0030] Mounting beams 7 are fixed to the upper part of the outer surface of mounting structure 4. Two mounting beams 7 are provided. A coarse adjustment structure 10 is installed at the bottom end of each of the two mounting beams 7. A fine adjustment structure 11 is installed at the ends of the two coarse adjustment structures 10 that are far apart from each other. A grinding structure 12 is installed on each of the two fine adjustment structures 11. The grinding structure 12 grinds the partition and can rotate along the partition as the mounting structure 4 rotates, grinding the partition 360 degrees. The coarse adjustment structure 10 and the fine adjustment structure 11 work together to adjust the grinding force of the grinding structure 12, so that the grinding structure 12 can move along the grinding surface of the partition and adapt to the contour of the partition, thereby ensuring the grinding effect and improving the grinding efficiency.

[0031] The lines connecting the two clamping frames 8 and the two coarse adjustment structures 10 are arranged in a cross shape. Driven by the No. 1 motor 6, the two mounting beams 7 rotate on the outside of the clamping frames 8.

[0032] As a further explanation of the above technical solution, the connecting structure 3 includes a guide post 31. The upper part of the guide post 31 is inserted into the guide cylinder 2 through the bottom opening. A threaded hole 33 is provided at the top of the guide post 31. The lower part of the lead screw 15 is threaded into the threaded hole 33. A connecting post 34 is fixed at the bottom of the guide post 31. A rotary table 35 is fixed at the bottom of the connecting post 34. Through the cooperation between the lead screw 15 and the threaded hole 33, the rotation of the lead screw 15 is converted into the up-and-down reciprocating movement of the guide post 31, thereby realizing the transformation of the motion mode. A base 36 is fixedly sleeved on the circumferential side of the connecting column 34, and the first motor 6 is fixed on the base 36; an mounting strip 21 is fixed axially on the inner circumferential side of the guide cylinder 2, and a slider 17 is fixed on the mounting strip 21; an mounting groove 32 is opened axially on the outer circumferential side of the guide column 31, and a guide rail 16 is fixed in the mounting groove 32; the slider 17 is slidably mounted on the guide rail 16, and the cooperation between the slider 17 and the guide rail 16 causes the guide column 31 to move linearly up and down reciprocally inside the guide cylinder 2.

[0033] The mounting structure 4 includes a connecting cylinder 41, the outer surface of which is fixed to the mounting beam 7. A connecting ring 42 is fixed at the top of the connecting cylinder 41, and a transmission gear 44 is fixed at the top of the connecting ring 42. The transmission gear 44 is rotatably sleeved on the connecting column 34 and meshes with the drive gear 61. The transmission gear 44 is located below the base 36. The connecting ring 42 is rotatably sleeved on the rotary table 35. The first motor 6 and the drive gear 61 cooperate to drive the transmission gear 44 to rotate, causing the connecting cylinder 41 and the connecting ring 42 to rotate, thereby realizing the rotation of the mounting beam 7 around the clamping frame 8.

[0034] The upper part of the seat 5 is inserted into the connecting cylinder 41 through the bottom opening and is positioned below the connecting ring 42. The seat 5 is connected to the bottom of the rotary table 35 by bolts. A rotary groove 43 is provided at the bottom of the connecting ring 42. The ball bearing 51 is rolled in the rotary groove 43 to reduce the frictional resistance experienced by the connecting ring 42 during rotation and improve the smoothness of movement.

[0035] Before grinding the partition, the partition is conveyed down to the bottom of the clamping frame 8 by the conveying device. The second motor 13 and the lead screw 15 work together to drive the guide column 31 to move down, so that the mounting structure 4 moves down and the clamping frame 8 moves down a suitable distance. Then, the two clamping cylinders 9 drive the two clamping frames 8 to close together, and the two clamping frames 8 clamp and fix the partition, realizing the limit before grinding the partition. Then, the second motor 13 and the lead screw 15 work together to move the clamping frame 8 and the partition up a certain distance together, so that the partition is separated from the conveying device, completing the preparation before grinding.

[0036] Furthermore, the coarse adjustment structure 10 includes a fixing frame 103 fixed to the bottom end of the mounting beam 7. A coarse adjustment cylinder 101 is fixed to the bottom end of the fixing frame 103. A bracket 102 is fixed to the output end of the coarse adjustment cylinder 101. A second slider 105 is fixed to the top of the bracket 102 near the coarse adjustment cylinder 101. A second guide rail 104 is slidably mounted on the second slider 105. The second guide rail 104 is fixed to the bottom end of the mounting beam 7. The coarse adjustment cylinder 101 pushes the bracket 102 to move a relatively large distance. The cooperation between the second guide rail 104 and the second slider 105 makes the movement of the bracket 102 linear and transmits the force on the bracket 102 to the mounting beam 7, maintaining the stability of the bracket 102 in use.

[0037] The fine-tuning structure 11 includes a slide block 112 and a fine-tuning cylinder 111. A third slider 114 is fixed at the bottom of the slide block 112. A third guide rail 115 is slidably mounted on the third slider 114. The third guide rail 115 is fixed to the top of the bracket 102 on the side away from the coarse-tuning cylinder 101. The fine-tuning cylinder 111 is fixed on the bracket 102. A tension / compression sensor 113 is fixed between the output end of the fine-tuning cylinder 111 and the slide block 112. The fine-tuning cylinder 111 pushes the tension / compression sensor 113 to move slightly, thereby realizing the slight movement of the slide block 112. The cooperation between the third guide rail 115 and the third slider 114 maintains the smooth movement of the slide block 112. The tension / compression sensor 113 is used for force measurement.

[0038] The grinding structure 12 includes a grinding motor 121 and a bearing 122. The grinding motor 121 is fixed to one side of the top end of the slide 112, and the bearing 122 is fixed to the other side of the top end of the slide 112. A grinding shaft 123 is rotatably mounted inside the bearing 122, and the grinding shaft 123 passes through the top and bottom ends of the bearing 122. A second transmission assembly 125 is connected between the top end of the grinding shaft 123 and the output end of the grinding motor 121. The second transmission assembly 125 passes through the slide 112. Specifically, the second transmission assembly 125 consists of two second synchronous pulleys and a... It consists of two No. 2 synchronous belts. Two No. 2 synchronous pulleys are fixed on the grinding motor 121 and the grinding shaft 123 respectively. The No. 2 synchronous belt passes through the slide 112 and drives the two No. 2 synchronous pulleys. The grinding motor 121 directly drives the No. 2 synchronous pulley connected to it to rotate, and then drives the other No. 2 synchronous pulley to rotate through the No. 2 synchronous belt, so as to realize the rotation of the grinding shaft 123. A grinding wheel 124 is fixed at the bottom end of the grinding shaft 123. The grinding wheel 124 rotates with the rotation of the grinding shaft 123. During the rotation of the grinding wheel 124, it contacts the partition to grind the partition.

[0039] The output direction of the coarse adjustment cylinder 101, the output direction of the fine adjustment cylinder 111, the sliding direction of the second slider 105 on the second guide rail 104, and the sliding direction of the third slider 114 on the third guide rail 115 are consistent, so that the tension and compression sensor 113 can accurately detect the force of the partition on the grinding wheel 124 during the grinding process of the grinding wheel 124, thereby accurately adjusting the grinding force of the grinding wheel 124.

[0040] During the grinding of the partition, the coarse adjustment cylinder 101 pushes the bracket 102 to move, causing the bracket 102 to move quickly toward the partition, bringing the grinding wheel 124 into rapid contact with the partition. When the grinding wheel 124 contacts the partition, the tension and pressure sensor 113 detects the pressure between the grinding wheel 124 and the partition. When this pressure matches the grinding force required for grinding, the grinding motor 121 drives the grinding shaft 123 to rotate through the second transmission assembly 125, causing the grinding wheel 124 to rotate and grind the partition. When the pressure does not match the grinding force required for grinding, the fine adjustment cylinder 111 pushes the slide 112 to move, performing a micro-movement of the slide 112. When the pressure is less than the grinding force, the fine adjustment cylinder 111 pushes the grinding wheel 124 further toward the partition. When the pressure is greater than the grinding force, the fine adjustment cylinder 111 moves the grinding wheel 124 a certain distance toward the side of the coarse adjustment cylinder 101, adjusting the pressure to match the grinding force.

[0041] During the grinding process, motor 6 and drive gear 61 work together to drive transmission gear 44 to rotate, causing connecting cylinder 41 and mounting beam 7 to rotate, and grinding wheel 124 to move along partition while rotating. Tension sensor 113 monitors the pressure between grinding wheel 124 and partition in real time, and fine-tuning cylinder 111 fine-tunes the position of slide 112 in real time according to pressure changes, so as to continuously adjust the pressure between grinding wheel 124 and partition to be consistent with grinding force.

[0042] The foregoing has shown and described 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 to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
