DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0045] In addition, the elements in the present application are referred to as "fixed to" or "provided on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not the only implementation.

[0046] Please refer to Figures 1-12 In the embodiments of the present application, the automatic feeding positioning tool machining platform comprises:

[0047] A lifting bracket 1 is provided with a longitudinal translation plate 101 slidingly installed thereon, a first movable chamber 2 and a second movable chamber 3 slidingly installed on the longitudinal translation plate 101, a first transmission shaft 201 and a second transmission shaft 301 rotatably installed on the first movable chamber 2 and the second movable chamber 3 respectively, and a receiving plate 7 fixed on the top of the second movable chamber 3;

[0048] Further comprising:

[0049] A polishing frame 4 is fixedly installed on the lifting bracket 1, a plurality of supporting rollers 5 are rotatably installed on the polishing frame 4, and a polishing belt 6 is sleeved on the supporting rollers 5;

[0050] A multi-direction displacement mechanism is arranged on the receiving plate 7, and a movable plate 15 is connected to the multi-direction displacement mechanism, so that the movable plate 15 can move in vertical and horizontal directions under the drive of the multi-direction displacement mechanism;

[0051] A clamping mechanism is arranged on the movable plate 15, and a plurality of clamping rollers 23 are circumferentially and equidistantly distributed on the clamping mechanism;

[0052] A follow-up control mechanism is arranged on the clamping mechanism, a pushing assembly connected to the follow-up control mechanism is arranged on the movable plate 15, and the pushing assembly can drive the follow-up control mechanism to move under the drive of the clamping mechanism, so as to control the clamping rollers 23 to move towards each other or away from each other;

[0053] A trigger rotating assembly is arranged on the clamping mechanism and connected to the clamping rollers 23, and the trigger rotating assembly can drive the clamping rollers 23 to rotate when the clamping rollers 23 move.

[0054] Specifically, when the tool is machined, the tool to be polished is placed between the clamping rollers 23. Under the action of the pushing assembly, the clamping mechanism is driven to move, so that the follow-up control mechanism moves to control the clamping rollers 23 to move towards each other, so as to fix 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 assembly continues to move, and the clamping rollers 23 are controlled to move towards the first transmission shaft 201 by the follow-up control mechanism and the clamping mechanism. When the shaft of the tool abuts against the first transmission shaft 201, the clamping mechanism continues to move, and under the action of the fixed ring 2301, the clamping rollers 23 are displaced between the clamping mechanism, and under the action of the trigger rotating assembly, the clamping rollers 23 are rotated to control the tool to rotate, so that the tool shaft can be rotated to the cooperation position with the first transmission shaft 201. After the tool cooperates with the first transmission shaft 201, the pushing assembly continues to move, and under the action of the follow-up control mechanism, the clamping rollers 23 move away from each other to release the tool. At this time, the pushing assembly is reset, and the movable plate 15 is reset by the multi-directional displacement mechanism. At the same time, the second movable chamber 3 is controlled to move towards the first movable chamber 2, so that the second transmission shaft 301 also cooperates with the tool shaft. The longitudinal translation plate 101 controls the tool to move to the cooperation position with the polishing 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 by the polishing belt 6. By controlling the movement and displacement of the clamping rollers 23, the tool can be positioned and rotated by a certain angle, so that the tool shaft can move to the cooperation position with the first transmission shaft 201 at any angle, and the clamping rollers 23 are automatically released after the tool is positioned, thereby realizing the effect of automatic feeding and positioning.

[0055] Please refer to Figures 1-4 The multi-directional displacement mechanism comprises a first sliding groove 701 formed in the receiving plate 7, a sliding plate 8 slidably installed in the first sliding groove 701, a first air cylinder 9 fixedly connected with the sliding plate 8 and fixed on the receiving plate 7, and a lifting assembly provided on the sliding plate 8. The lifting assembly comprises a motor 10 fixedly installed on the sliding plate 8, a lead screw 11 rotatably installed on the sliding plate 8 and connected with the output shaft of the motor 10, a threaded sleeve 12 movably installed on the lead screw 11 and threadedly matched with the lead screw 11, and the threaded sleeve 12 is fixedly connected with the movable plate 15. The multi-directional displacement mechanism further comprises a guide column 13 fixedly installed on the sliding plate 8, and a guide sleeve 14 slidably installed on the guide column 13 and fixedly connected with the threaded sleeve 12.

[0056] In detail, the two ends of the cutter are provided with rotating shafts, the rotating shafts are provided with keys, the first transmission shaft 201 and the second transmission shaft 301 are used for driving the cutter to rotate, the first transmission shaft 201 and the second transmission shaft 301 are provided with key grooves matched with the keys, when the cutter is polished, the keys on the rotating shafts of the cutter are inserted into the key grooves, so that the first transmission shaft 201 and the second transmission shaft 301 cannot idle with the cutter, the first movable chamber 2 and the second movable chamber 3 are combined to form a machining chamber, in the initial state, the threaded sleeve 12 is located at the end of the stroke in the direction of the sliding plate 8, so that the clamping rollers 23 are located outside the machining chamber, at this time, the cutter to be machined 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 ends of the cutter, so that the cutter is fixed, under the action of the first cylinder 9, the sliding plate 8 is controlled to move along the length direction of the first sliding groove 701, so that the cutter can completely enter the machining chamber, at the same time, under the action of the motor 10, the lead screw 11 is driven to rotate, so that the threaded sleeve 12 is driven to move, the threaded sleeve 12 also drives the guide sleeve 14 to move along the length direction of the guide column 13, since the guide sleeve 14 and the guide column 13 have a guiding effect, the threaded sleeve 12 moves along the length direction of the lead screw 11 and cannot rotate with the lead screw 11, the threaded sleeve 12 also drives the movable plate 15 to move, so that the cutter enters the machining chamber through the clamping mechanism and the clamping rollers 23, when the rotating shafts of the cutter and the rotating center of the first transmission shaft 201 are located at the same axial position, the motor 10 stops working.

[0057] Preferably, by adjusting the height of the clamping rollers 23, feeding outside the machining chamber can be realized, feeding by the conveying belt or feeding by the cylinder can be used, so that the effect of convenient feeding is achieved, and manual feeding of the cutter into the machining chamber is avoided, so that the safety of the workers is ensured, feeding by the conveying belt and feeding by the cylinder are applications of the prior art, and details are not described herein.

[0058] Please refer to Figures 3-6 , Figures 8-12The clamping mechanism comprises a rotating sleeve 16 rotatably mounted on the movable plate 15, a clamping groove 1601 is formed in the circumferential side wall of the rotating sleeve 16, and a movable rod 17 is slidably mounted in the rotating sleeve 16; further comprising a groove 1701 formed on the movable rod 17, a follow-up ring 18 is rotatably mounted in the groove 1701 and is in sliding connection with the clamping groove 1601, and a supporting assembly is arranged on the movable rod 17, wherein the supporting assembly comprises a supporting plate 19 fixedly mounted on the end of the movable rod 17, a plurality of second sliding grooves 1901 are formed in the supporting plate 19 and are distributed at equal intervals in the circumference, a sliding block 20 is slidably mounted in the second sliding groove 1901, the sliding block 20 is in sliding connection with the clamping roller 23, and a first spring 21 is fixed in the second sliding groove 1901 and abuts against the sliding block 20.

[0059] It should be noted that in the initial state, under the action of the pushing assembly, the movable rod 17 is located at the end of the stroke in the rotating sleeve 16, so as to control the follow-up ring 18 to be located at the end of the stroke on the side of the clamping groove 1601 facing the movable plate 15, under the action of the follow-up control mechanism, the spacing between the three sliding blocks 20 is large, and a certain distance is left from the end of the second sliding groove 1901 away from the rotating sleeve 16, and 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 assembly, the rotating sleeve 16 is controlled to rotate, thereby driving the follow-up control mechanism to move, so that the three sliding blocks 20 move towards each other, so that the first spring 21 is compressed, and the sliding block 20 also drives the clamping roller 23 to move, when the three clamping rollers 23 abut against the tool, and the end of the tool abuts against the fixed ring 2301, it indicates that the clamping is completed, at this time, under the action of the multidirectional displacement mechanism, the clamping roller 23 is controlled to enter the machining chamber, and the shaft of the tool is in the same axial position as the first transmission shaft 201, at the same time, the tool is controlled to approach the first transmission shaft 201 by the first air cylinder 9, and stops working when the shaft of the tool is about to abut against the first transmission shaft 201, so as to facilitate subsequent feeding and positioning of the tool.

[0060] 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 of the tool.

[0061] Please refer to Figures 3-10The follow-up adjusting mechanism comprises a guide groove formed in the circumferential outer wall of the rotating sleeve 16, a supporting ring 30 slidingly installed on the rotating sleeve 16, and a third limiting block 3001 fixed to the inner wall of the supporting ring 30 and slidingly fitted in the guide groove; a supporting sleeve 34 fixedly installed on the sliding block 20, a supporting rod 33 slidingly installed in the supporting sleeve 34 and fixedly connected with the supporting ring 30, and an elastic assembly provided on the rotating sleeve 16 and connected with the supporting ring 30, wherein the elastic assembly comprises a limiting ring 29 fixedly installed on the rotating sleeve 16, a fourth spring 31 and a fifth spring 32 sleeved on the rotating sleeve 16, the two ends of the fourth spring 31 abutting against the limiting ring 29 and the supporting ring 30 respectively, and the two ends of the fifth spring 32 abutting against the supporting ring 30 and the end of the rotating sleeve 16 respectively.

[0062] Further, the guide groove can be divided into multiple sections, i.e., 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, and 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 with each other at the head and tail, the angle formed by 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, the pitch of the second spiral groove 1604 is greater than the pitch of the third spiral groove 1607, thus the size of the second spiral groove 1604 in the length direction of the rotating sleeve 16 is greater than the size 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 assembly, the rotating sleeve 16 is in the locked state, the third limiting block 3001 is located in the first vertical groove 1603, the fourth spring 31 and the fifth spring 32 are both in the compressed state, and the elastic potential energy of the fourth spring 31 is greater than the elastic potential energy of the fifth spring 32, thus the third limiting block 3001 is located at the connection position of the first vertical groove 1603 and the second spiral groove 1604, and the supporting ring 30 has a tendency to move away from the limiting ring 29.

[0063] Specifically, when the tool needs to be clamped, at this time, the pushing assembly 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, because the pushing assembly 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 cannot rotate with the rotating sleeve 16, the elastic potential energy of the fourth spring 31 is reduced, and the elastic potential energy of the fifth spring 32 is increased, and before the third limiting block 3001 passes through the circumferential vertical plane of the position where the third spiral groove 1607 is connected with the second vertical groove 1606, the elastic potential energy of the fifth spring 32 will exceed that of the fourth spring 31, and under the action of the pushing assembly, the movable rod 17 has a tendency to move towards the rotating sleeve 16, therefore, the position of the supporting plate 19 is in a locked state, when the support ring 30 moves, it will drive the support rod 33 to slide towards the support sleeve 34, because the support rod 33 and the support sleeve 34, the second sliding groove 1901 and the rotating sleeve 16 are combined to form a vertical triangle, when the support ring 30 moves, it means that the length of one of the right-angle sides of the vertical triangle system is reduced, therefore, the length of the hypotenuse formed by the combination of the support rod 33 and the support sleeve 34 is also reduced, so that the size of the mutual fitting of the support rod 33 and the support sleeve 34 increases, the three sliding blocks 20 will slide along the second sliding groove 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 sliding groove 1901 no longer changes, 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 supporting plate 19 to move synchronously with the support ring 30 through the support rod 33 and the support sleeve 34 and the sliding block 20, and driving the movable rod 17 to move synchronously, to control the tool to move towards the first transmission shaft 201 through the clamping roller 23, under the action of the first air cylinder 9, the distance between the tool and the first transmission shaft 201 is very small, therefore, the supporting plate 19 only needs to move a small distance, the 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 supporting plate 19 continue to move, because the fixed ring 2301 abuts against the tool, the fixed ring 2301 and the clamping roller 23 cannot move when the tool cannot move, therefore, the sliding block 20 and the clamping roller 23 will relatively move and compress the second spring 24 to drive the trigger rotating assembly to move, so that the clamping roller 23 itself rotates, under the action of friction, the tool is controlled to rotate, to control the key on the tool shaft to move, when the key moves to the position matched with the key groove, because the tool is always subjected to a force towards the first transmission shaft 201, therefore, the key will quickly enter the key groove to realize the mutual cooperation between the tool shaft and the first transmission shaft 201, at this time,When the key and the key groove are matched, the cutter no longer rotates, when the third limiting block 3001 moves to the position where the second spiral groove 1604 and the annular groove 1605 are connected, the support ring 30 moves to the end of the stroke away from the movable plate 15, the support plate 19 no longer moves, under the action of the trigger rotating assembly, the clamping roller 23 just rotates a circle, so that the key on the cutter shaft can rotate to the position matched with the key groove of the first transmission shaft 201 at any angle.

[0064] The pushing assembly continues to move, so that the rotating sleeve 16 continues to rotate, so that the third limiting block 3001 enters the annular groove 1605, and the position of the support ring 30 remains unchanged, when the third limiting block 3001 moves to the position where the annular groove 1605 and the second vertical groove 1606 are connected, the elasticity of the first spring 21 and the fifth spring 32 is released, the third limiting block 3001 is controlled to slide along the second vertical groove 1606 through the support ring 30, at the same time, the sliding block 20 slides along the second sliding groove 1901 and moves away from each other, due to the resistance provided by the fourth spring 31 to the support ring 30, and under the double action of the pushing assembly and the first spring 21, it can be ensured that the movement rate of the movable rod 17 towards the movable plate 15 is greater than the movement rate of the support ring 30, so that it can be ensured that the clamping roller 23 is separated from the cutter first during the reset process, through the cooperation of the guide groove and the third limiting block 3001, the clamping roller 23 can be controlled to automatically push the cutter to the position matched with the first transmission shaft 201 after the clamping roller 23 executes clamping on the cutter, and drive the cutter to rotate after the cutter shaft and the first transmission shaft 201 are in contact, so that the key on the cutter shaft can be matched with the key groove at any angle, after the cutter feeding is completed, the clamping roller 23 can also be automatically controlled to execute the release action on the cutter, so as to avoid interference between the clamping roller 23 and the cutter during the reset of the clamping roller 23, which can cause damage to the clamping roller 23 or offset of the cutter.

[0065] Please refer to Figures 3-6 、 Figures 8-10 , the pushing assembly includes a support column 26 fixedly installed on the movable plate 15 and a second air cylinder 27, the support column 26 is in sliding connection with the support ring 30, the rotating sleeve 16 is slidably installed with a movable ring 25 in sliding connection with the support column 26 and fixedly connected with the telescopic end of the second air cylinder 27, the rotating sleeve 16 is sleeved with a third spring 28, and the two ends of the third spring 28 are respectively in abutment with the movable ring 25 and the follower ring 18; further comprising a first spiral groove 1602 opened on the rotating sleeve 16, and the inner wall of the movable ring 25 is fixedly provided with a second limiting block 2501 in sliding connection with the first spiral groove 1602.

[0066] Further, the helix angle of the first helical groove 1602 is the same as that of the third helical groove 1607, and in the initial state, under the action of the second cylinder 27, the movable ring 25 is located at the end of the stroke towards the movable plate 15, so that the second limit block 2501 is located at the end of the stroke on one side of the first helical groove 1602, at this time, the third limit block 3001 is located at the connecting position of the first vertical groove 1603 and the second helical groove 1604, the third spring 28 is in a compressed state, and the elastic potential energy of the third spring 28 is greater than that of the first spring 21, so that the movable rod 17 has a tendency to move towards the inside of the rotating sleeve 16, at this time, the distance between the movable rod 17 and the movable plate 15 is the smallest, and under the action of the third spring 28, the position of the movable rod 17 and the support plate 19 is locked, when it is necessary to clamp the tool, 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 limit block 2501 to slide in the first helical groove 1602, so that the rotating sleeve 16 rotates, under the action of the guide groove and the third limit block 3001, the sliding block 20 slides along the second sliding groove 1901, and overcomes the thrust of the first spring 21, so that the first spring 21 is compressed, and the sliding block 20 also controls the clamping roller 23 to move towards each other, so as to clamp the tool, after the tool clamping is completed, the movable ring 25 continues to move, so that the rotating sleeve 16 continues to rotate, since the position of the sliding block 20 in the second sliding groove 1901 does not change, therefore, the support plate 19 will move synchronously with the support ring 30, and compress the third spring 28, when the third limit block 3001 moves to the connecting position of the annular groove 1605 and the second vertical groove 1606, the elastic release of the third spring 28, the fourth spring 31 and the first spring 21, so that the support ring 30 and the support plate 19 and the sliding block 20 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, to ensure that the sliding block 20 moves towards each other first, to ensure that the clamping roller 23 releases the tool, when the third limit block 3001 moves to the connecting position of the second vertical groove 1606 and the third helical groove 1607, the elastic potential energy of the fourth spring 31 is still greater than that 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 rotating sleeve 16 to reverse through the second limit block 2501 and the first helical groove 1602, the third limit block 3001 will enter the third helical groove 1607, and continue to compress the fifth spring 32 through the support ring 30, when the third limit block 3001 moves to the connecting position of the third helical groove 1607 and the first vertical groove 1603, the elastic potential energy of the fifth spring 32 is greater than that of the fourth spring 31, thereby controlling the support ring 30 to move away from the limit ring 29, so that the third limit block 3001 returns to the connecting position of the first vertical groove 1603 and the second helical groove 1604,Through the translation of the active ring 25, namely, the control clamping roller 23 can realize a series of actions such as clamping, pushing and releasing the tool, so as to realize the effect of convenient use.

[0067] Please refer to Figures 3-5 、 Figure 8 、 Figure 9 、 Figure 11 、 Figure 12 The trigger rotating assembly comprises a fourth spiral groove 2302 formed in the clamping roller 23, a fixed sleeve 22 fixed to the side wall of the sliding block 20, a first limiting block 2201 fixed to the inner wall of the fixed sleeve 22 and slidably matched with the fourth spiral groove 2302, and a second spring 24 abutting against the sliding block 20.

[0068] In detail, in the initial state, the second spring 24 is in a compressed state, so that the clamping roller 23 is located at the end of the stroke away from the sliding block 20, and the first limiting block 2201 is located at the end of the stroke on one side of the fourth spiral groove 2302. When the tool is clamped, the clamping roller 23 and the fixed ring 2301 abut against the tool, so that when the shaft of the tool abuts against the first transmission shaft 201, the clamping roller 23 no longer moves under the action of the fixed ring 2301. At this time, the support plate 19 continues to move towards the first transmission shaft 201, so that the sliding block 20 and the clamping roller 23 slide relative to each other, and the first limiting block 2201 slides along the fourth spiral groove 2302, so that the clamping roller 23 rotates to drive the tool to rotate. When the first limiting 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 shaft of the tool can be rotated to the key groove at any angle, preventing the first transmission shaft 201 from idling due to the key not being matched with the key groove, so as to realize the overall polishing of the tool.
