[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0018] The existing oilstone repair mechanism has the following problems: 1. Defects of the oilstone pressing plate: When the oilstone is inserted and the grinding wheel is repaired, the oilstone pressing plate remains in a compressed state. Long-term friction causes the oilstone pressing plate to wear and fail to be compressed, resulting in the oilstone becoming loose.

[0019] 2. Defects of the side spring pressure plate: The outlet side spring pressure plate presses the oilstone for a long time, and friction occurs when the oilstone slides, causing wear of the spring plate and the side block, resulting in obvious looseness on the left and right when repairing the oilstone.

[0020] 3. Defects in the oilstone pushing mechanism: The oilstone is driven by a chain and is pushed back and forth by a cylinder to provide power. The one-way bearing at the chain position is easily damaged, resulting in the oilstone being unable to be pushed.

[0021] 4. Design defect of the oilstone placement block: The placement position of the oilstone is composed of columns, and it is difficult to place and remove the oilstone after deformation.

[0022] 5. Defects of the oilstone repair method: The oilstone and the overall bracket move into the grinding wheel water cover at the same time. The movement of the overall device is driven by the cylinder, and the speed is unstable. The oilstone cannot be guaranteed to be stable and reliable when repairing the grinding wheel.

[0023] The above-mentioned problems lead to the problems that the oil stone repair mechanism has a short service life, a high probability of failure, high maintenance cost and great difficulty in maintenance. Therefore, in response to the above-mentioned technical problems, the present application provides a grinding and repair device and method, which can automatically detect, locate and trim the oil stone, significantly improve the efficiency and quality of grinding wheel repair, and make the grinding and repair equipment more durable. Among them, the present application takes the application scenario of grinding wheel grinding as an example, that is, the equipment to be ground is a grinding wheel, and the grinding piece 6 is an oil stone piece, and introduces the structure of the grinding and repair equipment in the present application and its use. The grinding and repair equipment provided in the present application is not only suitable for the scenario of grinding wheel grinding, but also suitable for the application scenarios of grinding of other equipment, specifically: Please refer to Figure 1-Figure 3 A grinding and repairing device comprises a clamping component 1, a placing component 2, a pushing component 3, a bracket 4 and a main pushing component 5; the pushing component 3 is arranged on the bracket 4; the placing component 2 is arranged on the pushing component 3, and the placing component 2 has a stacking cavity that can match the grinding piece 6; the clamping component 1 is arranged on the discharge side of the placing component 2, and a feeding channel for the grinding piece 6 to pass through is formed between the clamping component 1 and the top of the pushing component 3, and the clamping component 1 can pressurize or release the grinding piece 6 located in the feeding channel; the main pushing component 5 is movably connected to the bracket 4, and is used to control the bracket 4 to move along the grinding direction; the equipment to be ground is installed outside the discharge side of the grinding and repairing equipment through a fixing device. By setting up the bracket 4 and the main pushing component 5, and setting the pushing component 3, the clamping component 1 and the placing component 2 on the bracket 4, the main pushing component 5 can push the bracket 4 to realize the movement of the overall structure on the bracket 4, so as to adjust the distance between the pushing component 3 and the equipment to be polished; and the polishing piece 6 can be pushed out by the pushing component 3, so as to realize the polishing of the equipment to be polished by the polishing piece 6. Since the overall movement of the bracket 4 and the movement of the polishing piece 6 can be controlled separately, the resistance of the polishing piece 6 when it moves is reduced, so as to achieve the purpose of keeping the polishing piece 6 stable when it is pushed.

[0024] In some embodiments, the main pushing assembly 5 includes a support seat 51, a cylinder pushing member 52 and a motor pushing member 53; the support seat 51 may include a support plate 511 and a connecting member 512, the connecting member 512 is connected to the bottom of the support plate 511 in an adjustable position according to the spacing between the equipment to be polished and the polishing piece 6, and the support seat 51 is connected to the fixed equipment through the connecting member 512; the cylinder pushing member 52 is arranged on the support seat 51; the driving end of the cylinder pushing member 52 is connected to the bracket 4, driving the bracket 4 to move along the polishing direction; the driving end of the motor pushing member 53 is transmission-connected to the control end of the cylinder pushing member 52, so that the cylinder pushing member 52 drives the bracket 4 to move secondary along the polishing direction, and the motor pushing member 53 can more accurately adjust the forward distance of the polishing piece as the polishing piece 6 is consumed. By changing the advancing mode of the crude oil stone piece repair to that of pushing the oil stone piece out and then pressing the piece to fix it, the oil stone piece bracket 4 is designed to be movable in parallel, and is respectively controlled in parallel twice by the cylinder pusher 52 and the motor pusher 53. After being pushed out to the repair position by the cylinder pusher 52, the bracket 4 is pushed by the motor pusher 53 to repair the grinding wheel, thereby improving the stability of the bracket 4 during the movement process.

[0025] In some embodiments, the cylinder pusher 52 includes a supporting rail 521, a supporting slider 522 and a pushing cylinder 523; the supporting rail 521 is arranged on the supporting plate 511; the supporting slider 522 is slidably arranged on the supporting rail 521; the bracket 4 is connected to the supporting slider 522; the driving end of the pushing cylinder 523 is connected to the bracket 4; the driving end of the motor pusher 53 is movably connected to the control end of the pushing cylinder 523, so as to further control the displacement of the grinding piece 6 through the bracket 4.

[0026] In some embodiments, the motor pusher 53 includes a distance-adjusting motor 531, a connecting disk 532, a connecting rod 533, a guide block 356 and a guide rod 357; the distance-adjusting motor 531 and the guide block 356 are respectively connected to the support plate 511, the connecting disk 532 is preferably circular, the center of the connecting disk 532 is connected to the output end of the distance-adjusting motor 531, and the guide rod 357 is slidably connected to the guide block 356 along the grinding direction; one end of the connecting rod 533 is hinged to the side of the connecting disk 532 away from the center, and the other end of the connecting rod 533 is hinged to the guide rod 357, and the end of the guide rod 357 away from the connecting rod is connected to the side of the cylinder pusher 52 away from the output end.

[0027] The cylinder pusher 52 first pushes the bracket 4 forward quickly, so that the grinding piece 6 quickly approaches or leaves the equipment to be ground, and then the pitch-adjusting motor 531 rotates to push the cylinder pusher 523 to adjust the position of the bracket 4. It should be noted that the pitch-adjusting motor 531 can adjust the speed according to the speed of the grinding wheel to be repaired. When the grinding piece 6 contacts the equipment to be ground and starts to be repaired, the eccentrically driven pitch-adjusting motor 531 can better adjust the moving speed of the grinding piece 6. When the grinding wheel is repaired, the speed is slower, which improves stability.

[0028] In some embodiments, the pushing assembly 3 includes a pushing rail 31, a rack 32, a gear 33, a pushing motor 34 and a pushing block 35; the pushing rail 31 and the pushing motor 34 are fixedly mounted on the bracket 4; the clamping assembly 1 and the placing assembly 2 are arranged on the pushing rail 31, and a gap is formed between the clamping assembly 1 and the pushing rail 31 for the single-piece grinding piece 6 to pass through; the pushing block 35 is slidably arranged in the track of the pushing rail 31, and is used to push the grinding piece 6 in the track; the side of the pushing block 35 away from the pushing rail 31 is connected to the rack 32; the pushing motor 34 is arranged on the bracket 4; the gear 33 is coaxially connected to the driving end of the pushing motor 34, and the gear 33 is geared with the rack 32; a reinforcing plate is fixed on the bracket 4, and a bearing is arranged between the driving end of the pushing motor 34 and the reinforcing plate, so as to improve the stability of the pushing motor driving the pushing block 35 to slide. By changing the way of pushing the grinding piece 6 to direct pushing, instead of the existing way of driving the grinding piece 6 to move by a cylinder and a chain, the push block 35 is driven by a motor to push the oilstone from the bottom to move, so that the push block 35 can obtain a more stable output power. The way of driving the bottom push block 35 to move by the motor output can meet the needs of pushing the oilstone to move, and solve the problems of the original oilstone stuck, empty piece, and unable to push out.

[0029] In some embodiments, the placement assembly 2 includes a baffle 21, a front baffle 22, and a rear baffle 23; the front baffle 22 and the rear baffle 23 together form a stacking cavity, which is rectangular in top view; the front baffle 22 abuts against the feeding side of the clamping assembly 1, and the rear baffle 23 is arranged at the end of the front baffle 22 away from the clamping assembly 1; the baffle 21 is slidably arranged between the front baffle 22, and a gap is formed between the baffle 21 and the push rail 31 for a single piece of oilstone to pass through. That is, the original stacking cavity composed of columns is changed to a rectangular support structure formed by the baffle 21, the front baffle 22, and the rear baffle 23 for placing the oilstone, thereby reducing the possibility of deformation of the support structure and ensuring that the oilstone is easy to take.

[0030] In some embodiments, the clamping assembly 1 includes a clamping plate 11 and a clamping cylinder 12; the clamping cylinder 12 is arranged on the discharge side of the placement assembly 2; one end of the clamping plate 11 is arranged on the clamping end of the clamping cylinder 12, and the other end is in contact with the push assembly 3, and an acute angle is formed between the clamping plate 11 and the push assembly 3, that is, the clamping plate is tilted downward toward the push rail along the pushing direction. The clamping plate is clamped by the clamping cylinder 12 to clamp the oilstone, so that the clamping cylinder 12 is released when the oilstone is pushed, and the wear of the clamping plate 11 is reduced while the oilstone is pushed out more smoothly, and the clamping plate is kept clamped to the oilstone to ensure stability when the grinding wheel is repaired, thereby reducing maintenance time and cost.

[0031] In some embodiments, the push rail 31 is set as a discharging section at the discharging side, and the track width of the discharging section is adapted to the width of the grinding piece 6; fixed blocks 13 are set on both sides of the discharging section along the pushing direction. That is, the fixed blocks 13 are set to replace the original method of pressing the oilstone piece by the spring pressure piece to restrict its left and right movement, thereby reducing the force on both sides and minimizing the wear on both sides; at the same time, since the clamping assembly 1 is set, the problem of oilstone piece jumping when repairing the grinding wheel can be solved.

[0032] In some further embodiments, a distance detector 38 is further provided on the discharge side of the pushing slide rail 31 to detect the distance of the oilstone being pushed out.

[0033] In an optional embodiment, in order to further improve the repair effect, the motor pusher 53 also includes a third signal detector 534 and a fourth signal detector 535. Before repair, the length of the grinding piece 6 consumed for each repair of a grinding wheel will be set according to the size of the grinding wheel to be repaired and the size of the grinding piece 6, that is, the angle that the distance adjustment motor 531 needs to rotate for each repair side is determined. Two detection columns are arranged at intervals on the connecting plate 532 for detection by the third signal detector 534 and the fourth signal detector 535 respectively. When the cylinder pusher 52 pushes the grinding piece 6 to contact the grinding wheel, the distance adjustment motor 531 rotates forward to drive the entire bracket 4 to drive the grinding piece 6 forward to repair the grinding wheel until the third signal detector 534 is triggered, indicating that the repair of a grinding wheel is completed; the distance adjustment motor 531 rotates, and when the fourth signal detector 535 is triggered, it indicates that the bracket 4 retreats to the initial position, and the distance adjustment motor 531 rotates forward again, and the next grinding wheel is in place.

[0034] In order to replenish the grinding piece 6 in time and further improve the repair accuracy and repair efficiency, the pusher assembly 3 also includes a first signal detector 36 and a second signal detector 37; the first signal detector 36 and the second signal detector 37 are respectively arranged at the two ends of the moving direction of the rack 32, and the distance pushed by the push motor 34 is detected by detecting the rack 32. Specifically, as the grinding piece 6 is consumed during the repair process, the push motor 34 will rotate and push the grinding piece 6 in the gap after each grinding wheel repair is completed (and while the distance adjustment motor 531 rotates), until the distance detector 38 detects that the grinding piece 6 is in place, however, when the first signal detector 36 detects that the rack 32 advances to the detection position, it means that a grinding piece 6 is consumed, the first signal detector 36 is triggered, and the push motor 34 is reversed through the control circuit, thereby driving the push block 35 to return, until the second signal detector 37 detects that the rack has retreated to the initial position, the second signal detector 37 is triggered, and the push motor 34 is forward rotated through the control circuit, thereby pushing out the next grinding piece 6 until the distance detector 38 is triggered.

[0035] Install the grinding and repair equipment: The equipment is connected to the fixed equipment mechanism through the lower support seat 51, and the grinding piece 6 is placed in the placement assembly 2 and the grinding distance is set. After the center of the grinding piece 6 is aligned with the grinding wheel, the lower end bolt is tightened. The bracket 4 is pushed out by pushing the cylinder 523, at which time the front end of the grinding piece 6 contacts the grinding wheel, and the adjusting nut of the pushing cylinder 523 is locked.

[0036] Another embodiment of the present invention provides a grinding wheel oilstone repair method, which is applied to the above-mentioned grinding and repairing equipment, and includes the following steps: Before repair, the grinding wheel speed, the driving motor 34 speed and the pitch-adjusting motor 531 speed are adjusted through the circuit control system.

[0037] When the grinding element 6 (oilstone) is not completely consumed during the repair of a grinding wheel: S1, control the pusher assembly 3 to push out the grinding piece 6 in the placement assembly 2, and press the grinding piece 6 through the pressing assembly 1: the pressing cylinder 12 drives the pressing plate 11 to move upward, pushing the motor 34 to rotate forward, and driving the push block 35 to push out the oilstone in the pusher slide rail 31 through the action of the gear 33 and the rack 32. After the distance detector 38 detects that the front end of the oilstone is in place, the motor 34 stops rotating, and the pressing cylinder 12 drives the pressing plate 11 to press the oilstone; S2, control the main push component 5 to push the bracket 4 in the grinding direction, so that the front end of the grinding piece 6 contacts the grinding wheel, and the grinding wheel is repaired until the grinding piece 6 is repaired: push the cylinder 523 to move forward, push the bracket 4 out and make the front end of the oilstone contact the grinding wheel, the grinding wheel starts to rotate, the pitch adjustment motor 531 rotates forward to push the bracket 4 to continue to move forward, the grinding wheel rotates and the oilstone grinds forward to repair the grinding wheel, until the pitch adjustment motor 531 moves to the third signal detector 534 and lights up to complete a single grinding wheel repair process; S3, control the main push component 5 to retract the bracket 4 away from the grinding direction to complete the repair: push the driving end of the cylinder 523 to retract, and the distance detector 38 cannot detect the oilstone; the distance adjustment motor 531 reverses until the fourth signal detector 535 lights up and the distance adjustment motor 531 rotates back to its original position, so that the oilstone is away from the grinding wheel, so that the next grinding wheel to be repaired can be in place, and the retraction process ends and enters the waiting state. It should be noted that, at the same time, because the oilstone has been consumed by a certain amount, the push motor 34 rotates forward to push the front end of the current oilstone until the distance detector 38 detects that it is in place. At this time, the repair of a grinding wheel is completed.

[0038] Or, when the grinding element 6 (the oilstone) is consumed during the repair of a grinding wheel: S1, controlling the pushing component 3 to push out the grinding piece 6 in the placing component 2, and pressing the grinding piece 6 through the pressing component 1; S2, controlling the main push assembly 5 to push the bracket 4 in the grinding direction, so that the front end of the grinding member 6 contacts the grinding wheel, and the grinding wheel is repaired; S3, when the grinding piece 6 is consumed, the pushing assembly 3 is controlled to move the pushing block 35 back in the grinding direction and then forward to replenish the grinding piece 6: the pushing motor 34 pushes the oilstone piece forward until the first signal detector 36 detects the rack 32, which indicates that the current oilstone piece is consumed, and the pushing motor 34 is reversed at this time, driving the rack 32 to retreat until the second signal detector 37 detects the rack 32, and the pushing motor 34 is rotated forward again to push the new oilstone piece through the gap; S4, repeat steps S1-S2 until a single grinding wheel repair process is completed, and control the main push assembly 5 to retract the bracket 4 to complete the repair.
