[0002] A weeding machine, also known as a lawn mower, grass trimmer, lawn pruning machine, etc., is a mechanical device used for trimming lawns, vegetation, etc.

[0003] Its working principle is to cut weeds through a high-speed rotating blade, which has the advantages of fast cutting speed and high efficiency, and can adapt to weeds of different heights and densities.

[0004] When producing the tool of the weeding machine, it is usually necessary to grind the edge of the tool to ensure the sharpness of the edge. When loading the tool for grinding, the tool is usually controlled by a clamping device to be inserted into the rotating shaft of the grinding rotating platform.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0034] Please refer to Figures 1 to 12 , in the embodiments of the present invention, a tool processing platform for automatic feeding and positioning includes: Lifting bracket 1, on which a longitudinal translation plate 101 is slidably installed. On the longitudinal translation plate 101, a first activity chamber 2 and a second activity chamber 3 are slidably installed. On the first activity chamber 2 and the second activity chamber 3, a first transmission shaft 201 and a second transmission shaft 301 are respectively rotatably installed. A receiving plate 7 is fixed to the top of the second activity chamber 3; It also includes: Grinding frame body 4, fixedly installed on the lifting bracket 1. On the grinding frame body 4, a plurality of support rollers 5 are rotatably installed. A grinding belt 6 is sleeved on the support rollers 5; Multi-directional displacement mechanism, arranged on the receiving plate 7. An activity plate 15 is connected to the multi-directional displacement mechanism, and the multi-directional displacement mechanism can drive the activity plate 15 to move in the vertical and horizontal directions; Clamping mechanism, arranged on the activity plate 15. A plurality of clamping rollers 23 distributed at equal circumferential intervals are connected to the clamping mechanism; Follow-up regulation mechanism, arranged on the clamping mechanism. A pushing component connected to the follow-up regulation mechanism is arranged on the activity plate 15. The pushing component can drive the follow-up regulation mechanism to move through the clamping mechanism to control the clamping rollers 23 to move towards the direction of approaching or separating from each other; Trigger rotation component, arranged on the clamping mechanism and connected to the clamping rollers 23. The trigger rotation component can drive the clamping rollers 23 to rotate when the clamping rollers 23 move.

[0035] Specifically, when machining a tool, the tool to be polished can be placed between the clamping rollers 23. Under the action of the pushing component, the clamping mechanism is driven to move, so that the follow-up regulation mechanism moves to control the clamping rollers 23 to move towards each other, thereby fixing the tool between the clamping rollers 23, and one end of the tool abuts against the fixed ring 2301. Under the action of the multi-directional displacement mechanism, the tool is controlled to move to the same axis position as the first transmission shaft 201. At this time, the pushing component continues to move, and through the follow-up regulation mechanism and the clamping mechanism, the clamping rollers 23 are controlled to move towards the first transmission shaft 201. When the rotating shaft of the tool abuts against the first transmission shaft 201, the clamping mechanism continues to move. Under the action of the fixed ring 2301, a yielding action occurs between the clamping rollers 23 and the clamping mechanism, and under the action of the triggering rotation component, the clamping rollers 23 rotate to control the tool to rotate, ensuring that the rotating shaft of the tool can rotate to the matching position with the first transmission shaft 201. After the tool is matched with the first transmission shaft 201, the pushing component continues to move, and under the action of the follow-up regulation mechanism, the clamping rollers 23 move away from each other to release the tool. At this time, the pushing component resets, and the movable plate 15 is controlled to reset through the multi-directional displacement mechanism. At the same time, the second activity room 3 is controlled to move towards the first activity room 2, so that the second transmission shaft 301 is also matched with the rotating shaft of the tool. The longitudinal translation plate 101 will control the tool to move to the position matching the grinding belt 6. Under the action of the first transmission shaft 201 and the second transmission shaft 301, the tool is controlled to rotate to polish the tool through the grinding belt 6. By controlling the movement and yielding of the clamping rollers 23, when positioning the tool, the tool can be controlled to rotate a certain angle, ensuring that the rotating shaft of the tool can move to the matching position with the first transmission shaft 201 at any angle, and after the tool positioning is completed, the clamping rollers 23 are automatically controlled to release the tool, thereby achieving the effect of automatic feeding and positioning.

[0036] Please refer to Figures 1 - 4 As shown in Figures 1 - 4 , the multi-directional displacement mechanism includes a first chute 701 opened on the receiving plate 7. A sliding plate 8 is slidably installed in the first chute 701. A first cylinder 9 fixedly connected to the sliding plate 8 is fixed on the receiving plate 7. A lifting component is arranged on the sliding plate 8. Among them, the lifting component includes a motor 10 fixedly installed on the sliding plate 8. A lead screw 11 connected to the output shaft of the motor 10 is rotatably installed on the sliding plate 8. A threaded sleeve 12 threadedly engaged with the lead screw 11 is movably installed on the lead screw 11. The threaded sleeve 12 is fixedly connected to the movable plate 15. It also includes a guide post 13 fixedly installed on the sliding plate 8. A guide sleeve 14 fixedly connected to the threaded sleeve 12 is slidably installed on the guide post 13.

[0037] Specifically, rotating shafts are installed at both ends of the tool, and keys are arranged on the rotating shafts. The first drive shaft 201 and the second drive shaft 301 are used to drive the tool to rotate, and key grooves are provided thereon that cooperate with the keys. When grinding the tool, the keys on the rotating shaft of the tool need to be inserted into the key grooves to ensure that there is no idling between the first drive shaft 201 and the second drive shaft 301 and the tool. When the first activity room 2 and the second activity room 3 are combined with each other, a processing chamber is formed. In the initial state, the threaded sleeve 12 is at the end of the stroke in the direction towards the sliding plate 8, so that the clamping rollers 23 are located outside the processing chamber. At this time, the tool to be processed can be placed between the clamping rollers 23. Under the action of the clamping mechanism, the clamping rollers 23 are controlled to move towards each other until the clamping rollers 23 abut against the end of the tool, thereby fixing the tool. Under the action of the first cylinder 9, the sliding plate 8 is controlled to move along the length direction of the first chute 701 to ensure that the tool can completely enter the processing chamber. At the same time, under the action of the motor 10, the lead screw 11 is driven to rotate to drive the threaded sleeve 12 to move. The threaded sleeve 12 also drives the guide sleeve 14 to move along the length direction of the guide post 13. Since the guide sleeve 14 and the guide post 13 have a guiding effect, it is ensured that the threaded sleeve 12 moves along the length direction of the lead screw 11 and does not rotate with the lead screw 11. The threaded sleeve 12 also drives the movable plate 15 to move, so as to control the tool to enter the processing chamber through the clamping mechanism and the clamping rollers 23. When the rotation center of the rotating shaft of the tool and the first drive shaft 201 are located on the same axis, the motor 10 stops working.

[0038] Preferably, by adjusting the height of the clamping rollers 23, feeding can be achieved outside the processing chamber. It can be used in cooperation with conveyor belt feeding or cylinder feeding, so as to achieve the effect of convenient feeding. At the same time, it can avoid manually holding the tool and entering the processing chamber for feeding, thus ensuring the safety of the staff. Conveyor belt feeding and cylinder feeding are both applications of existing technologies, and will not be elaborated in this application.

[0039] Please refer to Figures 3 - 6 、 Figures 8 - 12, the clamping mechanism includes a rotating sleeve 16 rotatably mounted on the movable plate 15. A clamping groove 1601 is formed on the circumferential side wall of the rotating sleeve 16. An activity rod 17 is slidably mounted in the rotating sleeve 16. A groove 1701 is formed on the activity rod 17. A follower ring 18 rotatably mounted in the groove 1701 and slidably connected with the clamping groove 1601 is provided. A support assembly is arranged on the activity rod 17. Specifically, the support assembly includes a support plate 19 fixedly mounted at the end of the activity rod 17. A plurality of second sliding grooves 1901 are formed on the support plate 19 at circumferentially equidistant distribution. A sliding block 20 is slidably mounted in the second sliding groove 1901. The sliding block 20 is slidably connected with the clamping roller 23. A first spring 21 abutted against the sliding block 20 is fixed in the second sliding groove 1901.

[0040] It should be noted that in the initial state, under the action of the pushing component, the activity rod 17 is located at the end of the stroke in the rotating sleeve 16, so as to control the follower ring 18 to be located at the end of the stroke on the side of the clamping groove 1601 facing the movable plate 15 through the groove 1701. Under the action of the follower control mechanism, the distance between the three sliding blocks 20 is relatively large, and there is a certain distance left from the end of the second sliding groove 1901 far away from the rotating sleeve 16. The first spring 21 is in a compressed state. When it is necessary to clamp the tool, at this time, under the action of the pushing component, the rotating sleeve 16 is controlled to rotate, thereby driving the follower control mechanism to move, so that the three sliding blocks 20 move towards the direction of approaching each other, so that the first spring 21 is compressed. The sliding block 20 will also drive the clamping roller 23 to move. When all the three clamping rollers 23 are in contact with the tool and the end of the tool is in contact with the fixed ring 2301, it means that the clamping is completed. At this time, under the action of the multi-directional displacement mechanism, the clamping roller 23 is controlled to enter the processing chamber, and the rotating shaft of the tool is in the same axis position as the first transmission shaft 201. At the same time, the tool is controlled to approach the first transmission shaft 201 through the first cylinder 9, and when the rotating shaft of the tool is about to be in contact with the first transmission shaft 201, the operation is stopped to facilitate the subsequent feeding and positioning of the tool.

[0041] Preferably, a plurality of friction grooves are formed on the clamping roller 23, which can increase the friction force between the clamping roller 23 and the tool, thereby increasing the clamping force on the tool.

[0042] Please refer to Figures 3 - 10, the follow-up control mechanism includes a guiding groove formed on the circumferential outer wall of the rotating sleeve 16. A support ring 30 is slidably mounted on the rotating sleeve 16, and a third limit block 3001 fixedly connected to the inner wall of the support ring 30 and slidably engaged with the guiding groove is provided. It further includes a support sleeve 34 fixedly mounted on the sliding block 20. A support rod 33 fixedly connected to the support ring 30 is slidably mounted in the support sleeve 34. An elastic component connected to the support ring 30 is provided on the rotating sleeve 16. Among them, the elastic component includes a limit ring 29 fixedly mounted on the rotating sleeve 16. A fourth spring 31 and a fifth spring 32 are sleeved on the rotating sleeve 16. Two ends of the fourth spring 31 are respectively abutted against the limit ring 29 and the support ring 30, and two ends of the fifth spring 32 are respectively abutted against the support ring 30 and the end of the rotating sleeve 16.

[0043] Furthermore, the guiding groove can be divided into multiple segments, namely a first vertical groove 1603, a second spiral groove 1604, an annular groove 1605, a second vertical groove 1606, and a third spiral groove 1607. The head and tail of the first vertical groove 1603, the second spiral groove 1604, the annular groove 1605, the second vertical groove 1606, and the third spiral groove 1607 are sequentially connected to each other. The angle formed by the combination of the second spiral groove 1604 and the annular groove 1605 in the circumferential direction is the same as the angle formed by the third spiral groove 1607 in the circumferential direction, and the pitch of the second spiral groove 1604 is greater than the pitch of the third spiral groove 1607. Therefore, the dimension of the second spiral groove 1604 in the length direction of the rotating sleeve 16 is greater than the dimension of the third spiral groove 1607 in the length direction of the rotating sleeve 16. In the initial state, under the action of the pushing component, the rotating sleeve 16 is in a locked state. The third limit block 3001 is located in the first vertical groove 1603. Both the fourth spring 31 and the fifth spring 32 are in a compressed state, and the elastic potential energy of the fourth spring 31 is greater than the elastic potential energy of the fifth spring 32. Therefore, the third limit block 3001 is located at the connection position between the first vertical groove 1603 and the second spiral groove 1604, and the support ring 30 has a tendency to move away from the limit ring 29.

[0044] Specifically, when it is necessary to clamp the tool, at this time, the pushing component works and drives the rotating sleeve 16 to rotate, thereby driving the guide groove to move. At this time, the third limiting block 3001 will enter the second spiral groove 1604 to drive the support ring 30 to move. Since the pushing component has a guiding effect on the support ring 30, it ensures that the support ring 30 can only move along the length direction of the rotating sleeve 16 and will not rotate with the rotating sleeve 16. Correspondingly, the elastic potential energy of the fourth spring 31 decreases, and the elastic potential energy of the fifth spring 32 increases. And before the third limiting block 3001 crosses the circumferential vertical plane where the third spiral groove 1607 is connected to the second vertical groove 1606, the elastic potential energy of the fifth spring 32 will exceed the elastic potential energy of the fourth spring 31. At the same time, under the action of the pushing component, the movable rod 17 has a tendency to move towards the inside of the rotating sleeve 16. Therefore, the position of the support plate 19 is in a locked state. When the support ring 30 moves, it will drive the support rod 33 to slide towards the inside of the support sleeve 34. Since the support rod 33, the support sleeve 34, the second chute 1901, and the rotating sleeve 16 are combined to form a vertical triangular setting, when the support ring 30 moves, it means that the length of one of the right-angled sides in the vertical triangular system decreases. Therefore, the length of the hypotenuse formed by the combination of the support rod 33 and the support sleeve 34 also decreases, so that the size of the mutual nesting of the support rod 33 and the support sleeve 34 increases. The three sliding blocks 20 will slide along the second chute 1901 and move towards each other, and compress the first spring 21. The sliding block 20 will also drive the clamping roller 23 to move. When the clamping roller 23 abuts against the tool, the position of the sliding block 20 in the second chute 1901 will no longer change. At this time, the third limiting block 3001 continues to slide along the second spiral groove 1604, so that the support ring 30 continues to move, thereby pushing the support plate 19 to move synchronously with the support ring 30 through the support rod 33, the support sleeve 34, and the sliding block 20, and driving the movable rod 17 to move synchronously, so as to control the tool to move towards the first transmission shaft 201 direction through the clamping roller 23. Under the action of the first cylinder 9, the distance between the tool and the first transmission shaft 201 is very small. Therefore, the support plate 19 only needs to move a small distance, and the rotating shaft of the tool will abut against the first transmission shaft 201. At this time, the third limiting block 3001 still slides along the second spiral groove 1604 to make the support plate 19 continue to move. Since the fixed ring 2301 abuts against the tool, when the tool cannot move, the fixed ring 2301 and the clamping roller 23 cannot move either. Therefore, relative movement will occur between the sliding block 20 and the clamping roller 23, and the second spring 24 will be compressed to drive the trigger rotation component to move, so that the clamping roller 23 itself rotates. Under the action of friction, the rotation of the tool is controlled to control the movement of the key on the rotating shaft of the tool. When the key moves to the position where it cooperates with the key groove, since the tool is always subjected to a force towards the first transmission shaft 201 direction, the key will quickly enter the key groove, realizing the mutual cooperation between the rotating shaft of the tool and the first transmission shaft 201. At this time,With the cooperation of the key and the keyway, the cutting tool stops rotating. When the third limiting block 3001 moves to the position where the second spiral groove 1604 communicates with the annular groove 1605, the support ring 30 moves to the end of the stroke away from the movable plate 15, and the support plate 19 stops moving. Under the action of the trigger rotation assembly, the clamping roller 23 just rotates one circle, so that the key on the cutting tool shaft can rotate to the position where it cooperates with the keyway of the first transmission shaft 201 at any angle.

[0045] The pushing assembly continues to move, causing the rotating sleeve 16 to continue rotating, so that the third limiting block 3001 enters the annular groove 1605. The position of the support ring 30 remains unchanged. When the third limiting block 3001 moves to the position where the annular groove 1605 communicates with the second vertical groove 1606, the elastic energy of the first spring 21 and the fifth spring 32 is released. The third limiting block 3001 is controlled by the support ring 30 to slide along the second vertical groove 1606. At the same time, the sliding block 20 slides along the second sliding groove 1901 and moves in a direction away from each other. Since the fourth spring 31 provides a certain resistance to the support ring 30, and under the dual action of the pushing assembly and the first spring 21, it can be ensured that the moving speed of the movable rod 17 towards the movable plate 15 is greater than the moving speed of the support ring 30. Therefore, it can be ensured that during the reset process of the clamping roller 23, it separates from the cutting tool first. Through the cooperation of the guiding groove and the third limiting block 3001, it can be realized that after the clamping roller 23 clamps the cutting tool, the cutting tool is automatically pushed to the position where it cooperates with the first transmission shaft 201. After the cutting tool shaft abuts against the first transmission shaft 201, the cutting tool is driven to rotate to ensure that the key on the cutting tool shaft can cooperate with the keyway at any angle. When the feeding of the cutting tool is completed, the clamping roller 23 can also be automatically controlled to release the cutting tool to avoid interference with the cutting tool when the clamping roller 23 resets, resulting in damage to the clamping roller 23 or deviation of the cutting tool.

[0046] Please refer to Figures 3 - 6 、 Figures 8 - 10 The pushing assembly includes a support column 26 and a second cylinder 27 fixedly installed on the movable plate 15. The support column 26 is slidably connected to the support ring 30. An activity ring 25 that is slidably connected to the support column 26 and fixedly connected to the telescopic end of the second cylinder 27 is slidably installed on the rotating sleeve 16. A third spring 28 is sleeved on the rotating sleeve 16. The two ends of the third spring 28 are respectively abutted against the activity ring 25 and the follower ring 18. It also includes a first spiral groove 1602 opened on the rotating sleeve 16. A second limiting block 2501 that is slidably connected to the first spiral groove 1602 is fixed on the inner wall of the activity ring 25.

[0047] Furthermore, the spiral angle of the first spiral groove 1602 is the same as that of the third spiral groove 1607. In the initial state, under the action of the second cylinder 27, the movable ring 25 is located at the end of the stroke in the direction of the movable plate 15, so that the second limiting block 2501 is located at the end of the stroke on one side of the first spiral groove 1602. At this time, the third limiting block 3001 is located at the connection position of the first vertical groove 1603 and the second spiral groove 1604. The third spring 28 is in a compressed state, and the elastic potential energy of the third spring 28 is greater than the elastic potential energy of the first spring 21, causing the movable rod 17 to tend to move into the rotating sleeve 16. At this time, the distance between the movable rod 17 and the movable plate 15 is the smallest. Under the action of the third spring 28, the positions of the movable rod 17 and the support plate 19 are locked. When the tool needs to be clamped, the second cylinder 27 works and drives the movable ring 25 to move along the length direction of the support column 26, thereby driving the second limiting block 2501 to slide in the first spiral groove 1602, causing the rotating sleeve 16 to rotate. Under the action of the guiding groove and the third limiting block 3001, the sliding block 20 is driven to slide along the second sliding groove 1901 and overcome the thrust of the first spring 21, so that the first spring 21 is compressed. The sliding block 20 also controls the clamping rollers 23 to move towards each other to clamp the tool. After the tool is clamped, the movable ring 25 continues to move, causing the rotating sleeve 16 to continue to rotate. Since the position of the sliding block 20 in the second sliding groove 1901 no longer changes, the support plate 19 will synchronously follow the support ring 30 and compress the third spring 28. When the third limiting block 3001 moves to the connection position of the annular groove 1605 and the second vertical groove 1606, the elastic potential energies of the third spring 28, the fourth spring 31, and the first spring 21 are released, causing the support ring 30, the support plate 19, and the sliding block 20 to move synchronously towards the initial position. And the elastic potential energy of the third spring 28 is greater than that of the fourth spring 31. Therefore, the movement speed of the support plate 19 is greater than that of the support ring 30, ensuring that the sliding block 20 moves away from each other first to ensure that the clamping rollers 23 perform the release action on the tool. When the third limiting block 3001 moves to the connection position of the second vertical groove 1606 and the third spiral groove 1607, the elastic potential energy of the fourth spring 31 is still greater than the elastic potential energy of the fifth spring 32. At this time, the second cylinder 27 controls the movable ring 25 to move towards the initial position to control the reverse rotation of the rotating sleeve 16 through the second limiting block 2501 and the first spiral groove 1602. The third limiting block 3001 will enter the third spiral groove 1607 and continue to compress the fifth spring 32 through the support ring 30. When the third limiting block 3001 moves to the connection position of the third spiral groove 1607 and the first vertical groove 1603, the elastic potential energy of the fifth spring 32 is greater than the elastic potential energy of the fourth spring 31, thereby controlling the support ring 30 to move away from the limiting ring 29 to make the third limiting block 3001 return to the connection position of the first vertical groove 1603 and the second spiral groove 1604.By translating the movable ring 25, a series of actions such as clamping, pushing, and releasing the tool by the clamping roller 23 can be realized, so as to achieve the effect of convenient use.

[0048] Please refer to Figures 3 - 5 、 Figure 8 、 Figure 9 、 Figure 11 、 Figure 12 The trigger rotation assembly includes a fourth spiral groove 2302 formed on the clamping roller 23. A fixed sleeve 22 is fixed to the side wall of the sliding block 20. A first limit block 2201 that is slidably engaged with the fourth spiral groove 2302 is fixed to the inner wall of the fixed sleeve 22. A second spring 24 that abuts against the sliding block 20 is sleeved on the clamping roller 23.

[0049] To elaborate, in the initial state, the second spring 24 is in a compressed state, so that the clamping roller 23 is at the end of the stroke in the direction away from the sliding block 20, and the first limit block 2201 is at the end of the stroke on one side of the fourth spiral groove 2302. When clamping the tool, both the clamping roller 23 and the fixed ring 2301 abut against the tool. Therefore, when the rotating shaft of the tool abuts against the first transmission shaft 201, under the action of the fixed ring 2301, the clamping roller 23 stops moving. At this time, the support plate 19 continues to move towards the first transmission shaft 201, causing relative sliding between the sliding block 20 and the clamping roller 23. The first limit block 2201 will slide along the fourth spiral groove 2302, causing the clamping roller 23 to rotate itself, thereby driving the tool to rotate. When the first limit block 2201 moves to the end of the stroke on the other side of the fourth spiral groove 2302, the clamping roller 23 rotates one circle, so that the key on the tool rotating shaft can be rotated to the position where it engages with the key groove at any angle, preventing the first transmission shaft 201 from idling due to the key not cooperating with the key groove, so as to achieve comprehensive grinding of the tool.
