[0009] By adopting the above technical solution, the adjusting gear is driven to rotate, so that the two adjusting racks move at the same time, driving the two grinding wheels to approach each other by the same distance at the same time, until the distance between the two grinding wheels is equal to the diameter of the metal sleeve to be processed, so that the two grinding wheels are both in contact with the side wall of the metal sleeve, and the metal sleeve is polished. By rotating the adjusting gear, the distance between the two grinding wheels can be adjusted, so that metal sleeves of different diameters can be polished, and the applicability is better. When the grinding wheel is in contact with the side wall of the metal sleeve, the rotating motor drives the grinding wheel to revolve around the metal sleeve, and at the same time, the grinding motor is started to drive the grinding wheel to rotate, thereby improving the accuracy and efficiency of the grinding wheel grinding the metal sleeve.

[0010] Optionally, the positioning assembly includes a positioning rod and a plurality of abutment rods, the positioning rod is arranged along the central axis of the mounting block, and the bottom end of the positioning rod is fixed to the working frame, and the plurality of abutment rods are arranged at intervals along the circumference direction of the positioning rod, and the abutment rod is hinged to the positioning rod through a torsion spring, and the torsion spring is used to drive the bottom end of the abutment rod to be tilted in a direction away from the positioning rod, and the abutment rod can abut against the inner wall of the metal sleeve.

[0011] By adopting the above technical solution, in the initial state, the abutment rod is tilted in a direction away from the positioning rod under the action of the torsion spring, that is, a plurality of abutment rods are in an open state. During installation, the metal sleeve to be processed is aligned with the positioning rod in a vertical state and sleeved on the positioning rod. The metal sleeve is continuously moved downward. When the metal sleeve abuts the abutment rod, the spring of the torsion spring is overcome, and the abutment rod is driven to move in the direction of the positioning rod, so that the plurality of abutment rods gradually shrink until the plurality of abutment rods are stored in the metal sleeve. At this time, the plurality of abutment rods are supported on the inner wall of the metal sleeve under the action of the torsion spring, that is, the abutment rod applies a tightening force to the inner wall of the metal sleeve, thereby fixing the metal sleeve and realizing the positioning of the metal sleeve on the workbench. The shrinkage degree of the abutment rod can be changed, so that metal sleeves of different diameters can be fixed, and the applicability is better.

[0012] Optionally, the work frame is provided with a loading mechanism for delivering the metal sleeve to the positioning assembly, the loading mechanism includes a screening plate and a transfer assembly, the screening plate and the transfer assembly are both arranged on the work frame, the screening plate is used to transport a plurality of metal sleeves to the transfer assembly in sequence, the transfer assembly is located between the screening plate and the positioning rod, and the transfer assembly is used to transfer the metal sleeve between the screening plate and the positioning rod.

[0013] By adopting the above technical solution, when in use, a plurality of metal sleeves are placed in the screening disk, and the vibration of the screening disk is used to make the plurality of metal sleeves move in a vertical state in sequence in the direction of the transfer component, and then the transfer component is started to transfer the metal sleeve at the output end of the screening disk to the positioning rod and sleeved on the positioning rod, so as to realize the fixation of a single metal sleeve under the mounting block so that two grinding wheels can perform grinding.

[0014] Optionally, the transfer assembly includes a transfer motor and a transfer plate, the transfer motor is arranged on the work frame, the output end of the transfer motor is fixed to one end of the transfer plate, and is used to drive the transfer plate to flip, and a fixed electromagnet is provided on one side of the transfer plate, when the transfer plate is rotated to the screening plate, the fixed electromagnet faces upward to receive the metal sleeve, and when the transfer plate is rotated to the positioning rod, the fixed electromagnet faces downward to place the metal sleeve.

[0015] By adopting the above technical solution, in the initial state, the transfer plate faces the screening disc and is connected to the output end of the screening disc, so that the metal sleeve at the output end of the screening disc can be pushed onto the transfer plate, and then the fixed electromagnet is started to fix the metal sleeve on the transfer plate, and then the transfer motor is started to drive the transfer plate to flip 180 degrees, so that the transfer plate faces the positioning rod, and the originally upward fixed electromagnet faces downward, that is, the metal sleeve is vertically downward and inserted on the positioning rod, so that the metal sleeve is positioned and fixed between the two grinding wheels. The length of the positioning rod is relatively short, so that the transfer plate drives the metal sleeve to be sleeved on the positioning rod.

[0016] Optionally, a connecting electromagnet is fixed on the adjusting gear, and the connecting electromagnet can engage with the end of the metal sleeve. A receiving electromagnet is provided on the side of the transfer plate opposite to the fixed electromagnet. When the transfer plate is rotated to the positioning rod, the receiving electromagnet faces upward to receive the metal sleeve on the connecting electromagnet.

[0017] By adopting the above technical solution, after the transfer plate sleeves the metal sleeve to be processed on the positioning rod, the transfer plate is reset immediately, thereby not interfering with the movement of the grinding wheel above the positioning rod, and the reset transfer plate receives the new metal sleeve to be processed again.

[0018] When the metal sleeve on the positioning rod is polished, the connecting electromagnet is started to adsorb the metal sleeve upward onto the connecting electromagnet, and then the moving cylinder is started to drive the mounting block to move upward, thereby driving the metal sleeve to move upward until it is pulled out of the positioning rod and the metal sleeve is suspended on the positioning rod.

[0019] After the transfer plate drives the new metal sleeve to move to the positioning rod, the receiving electromagnet originally facing downward on the transfer plate turns upward and aligns with the mounting block above. At this time, the moving cylinder is started, so that the mounting block moves down with the metal sleeve to the receiving electromagnet, and then the receiving electromagnet is started and the connecting electromagnet is closed, thereby fixing the processed metal sleeve on the transfer plate. Then the transfer motor is started again to drive the transfer plate to reset.

[0020] The reset transfer plate makes the fixed electromagnet face upward again to receive a new metal sleeve. Repeat the above steps to achieve the sequential loading of the metal sleeves to be processed and the synchronous unloading of the processed metal sleeves. In this process, the transfer plate realizes unloading simultaneously during the loading process, achieving full-station operation and improving work efficiency.

[0021] Optionally, a limit plate is connected to the working frame via a limit spring, and the limit plate is located at the output end of the screening disc and is used to limit the movement of the metal sleeve. The transfer plate can abut against the limit plate and drive the limit plate to contract. When the transfer plate is rotated to the screening disc, the transfer plate can be flush with the output end of the screening disc.

[0022] By adopting the above technical solution, when the transfer plate transfers the metal sleeve to be processed to face the screening disc, the end of the transfer plate abuts against the limit plate and squeezes the limit spring, so that the limit plate moves down, so that the transfer plate is flush with the output end of the screening disc, so that the metal sleeve at the output end of the screening disc can be translated onto the transfer plate. After the transfer plate fixes the metal sleeve using a fixed electromagnet, the transfer plate rotates and drives the metal sleeve to the positioning rod for loading. During this process, the transfer plate flips upward, so that the limit plate gradually loses pressure, that is, the limit spring recovers its deformation, driving the limit plate to move up, so that the limit plate finally protrudes from the upper surface of the output end of the screening disc, limiting the metal sleeve at the output end of the screening disc from sliding off.

[0023] Optionally, a collection box with an open top is provided on the work frame, and the collection box is located below the transfer plate.

[0024] By adopting the above technical solution, when the transfer plate drives the processed metal sleeve to reset and the transfer plate rotates to 90 degrees, the transfer plate is in a vertical state. At this time, the receiving electromagnet is turned off, so that the processed metal sleeve falls from the transfer plate to the collection box for storage under the action of gravity. As a result, when the transfer plate is reset, the processed metal sleeve gradually changes from an upward state to a downward state, and the material is removed before the transfer plate is reset, so that it will not interfere with the transfer plate pressing the limit plate.

[0025] Optionally, a buffer plate is provided in the collection box, the buffer plate is located directly below the transfer plate, and a protective pad is provided on the top wall of the buffer plate.

[0026] By adopting the above technical solution, when the processed metal sleeve falls from the transfer plate into the collection box, the metal sleeve will fall onto the buffer plate and be received by the buffer plate. The protective pad plays a protective and buffering role, so that the metal sleeve is not easily damaged when it hits the buffer plate.

[0027] Optionally, a velvet belt is provided on the bottom wall of the protective pad, and a hook belt is provided on the side wall of the buffer plate close to the protective pad, and the velvet belt is in contact with the hook belt.

[0028] By adopting the above technical solution, when the polished metal sleeve falls on the buffer plate, the falling force of the metal sleeve directly acts on the protective pad, causing the protective pad to wear after long-term use. At the same time, the metal sleeve will vibrate when it collides with the buffer plate, thereby shaking off the debris remaining on the metal sleeve after polishing onto the protective pad. When the protective pad is severely worn or has a lot of debris attached to it, move the protective pad away from the buffer plate until the velvet belt and the hook belt are separated to achieve the removal of the protective pad, and then fit the velvet belt on the new protective pad with the hook belt to achieve the installation of the new protective pad and complete the replacement of the protective pad.

[0029] In summary, the present application includes at least one of the following beneficial effects: 1. After the transfer plate sets the metal sleeve to be processed on the positioning rod, the transfer plate will immediately reset to receive the new metal sleeve. When the metal sleeve on the positioning rod is polished, use the connecting electromagnet to adsorb the metal sleeve and start the moving cylinder to drive the mounting block upward, thereby driving the metal sleeve upward until it is pulled out of the positioning rod. After that, after the transfer plate drives the new metal sleeve to move to the positioning rod, the receiving electromagnet is aligned with the mounting block above. At this time, start the moving cylinder to move the metal sleeve down to the receiving electromagnet, then start the receiving electromagnet, and close the connecting electromagnet to fix the processed metal sleeve on the transfer plate. Then start the transfer motor again to drive the transfer plate to reset; The receiving electromagnet is powered off during the resetting process of the transfer plate, causing the processed metal sleeve to fall into the collection box, and the reset transfer plate causes the fixed electromagnet to face upward again to receive new metal sleeves. Repeat the above steps, and the transfer plate can unload materials simultaneously during the loading process, achieving full-station operation and improving work efficiency.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a mobile grinding and polishing device for a metal sleeve. Figure 1 and Figure 2 The mobile grinding and polishing device for metal sleeves includes a work frame 10, on which a feeding mechanism 20, a positioning assembly 30 and a grinding assembly 40 are arranged. When in use, a number of metal sleeves to be processed are put into the feeding mechanism 20, and the feeding mechanism 20 is used to arrange the metal sleeves in a vertical state in sequence, and move them one by one in the direction of the positioning assembly 30.

[0034] When the metal sleeve is placed at the positioning assembly 30, the positioning assembly 30 is fixedly connected to the metal sleeve, so that the single metal sleeve is positioned and fixed on the workbench 10. The grinding assembly 40 is opposite to the positioning assembly 30, so that the circumferential side wall of the metal sleeve located at the positioning assembly 30 can be ground and polished.

[0035] Reference Figure 1 and Figure 2 , wherein the feeding mechanism 20 includes a screening disc 21 and a transfer assembly 22, the screening disc 21 is fixed on the work frame 10, a plurality of metal sleeves are placed in the screening disc 21, and the screening disc 21 utilizes its own vibration to make the plurality of metal sleeves be transported in a vertical state in sequence. In order to prevent the metal sleeves from directly moving out from the output end of the screening disc 21, a limit plate 70 is provided at the end of the screening disc 21, the limit plate 70 is vertically arranged, a limit spring 71 is fixed at the bottom end of the limit plate 70, and one end of the limit spring 71 away from the limit plate 70 is fixed to the output end of the screening disc 21, and the limit spring 71 is used to push the limit plate 70, so that the limit plate 70 blocks the output end of the screening disc 21, and limits the metal sleeves at the output end of the screening disc 21 from sliding off.

[0036] Reference Figure 1 and Figure 2 The transfer assembly 22 is located at the output end of the screening disc 21. The transfer assembly 22 includes a transfer motor 221 and a transfer plate 222. The transfer motor 221 is installed on the work frame 10. The output end of the transfer motor 221 is fixed to one end of the transfer plate 222 to drive the transfer plate 222 to flip. A fixed electromagnet 223 is embedded on one side of the transfer plate 222, and a receiving electromagnet 224 is embedded on the other side. The fixed electromagnet 223 and the receiving electromagnet 224 are both located at one end of the transfer plate 222 away from the transfer motor 221. When the fixed electromagnet 223 and the receiving electromagnet 224 are energized, the metal sleeve can be adsorbed.

[0037] In the initial state, the transfer plate 222 faces the screening disc 21, so that the transfer plate 222 is in a horizontal state, and presses the limit plate 70, so that the limit plate 70 compresses the limit spring 71 and is located below the transfer plate 222. At this time, the transfer plate 222 is flush with and connected to the output end of the screening disc 21, so that the metal sleeve at the output end of the screening disc 21 can be pushed onto the transfer plate 222. At this time, the fixed electromagnet 223 is started to fix the metal sleeve on the transfer plate 222.

[0038] Reference Figure 1 and Figure 3 The positioning assembly 30 is located on the side of the transfer assembly 22 away from the screening disc 21. The positioning assembly 30 includes a positioning rod 31 and a plurality of abutting rods 32. The positioning rod 31 is arranged along the central axis of the mounting block 50, and the bottom end of the positioning rod 31 is fixed to the working frame 10. The plurality of abutting rods 32 are arranged at intervals along the circumference direction of the positioning rod 31. The abutting rod 32 can be an L-shaped rod. A rotating shaft is provided at the bending part of the abutting rod 32, and the rotating shaft is rotatably connected to the side wall of the positioning rod 31. A torsion spring 321 is sleeved on the rotating shaft. One end of the torsion spring 321 is fixed to the positioning rod 31, and the other end is fixed to the rotating shaft, thereby driving the bottom end of the abutting rod 32 to be tilted in a direction away from the positioning rod 31.

[0039] In the initial state, under the action of the torsion spring 321 , one end of the abutting rod 32 is inclined in a direction away from the positioning rod 31 , that is, the abutting rods 32 are in an open state.

[0040] During installation, the transfer plate 222 first receives the metal sleeve to be processed at the output end of the screening disc 21, and is fixedly connected with the fixed electromagnet 223, and then the transfer motor 221 is started to drive the transfer plate 222 to flip 180°, so that the transfer plate 222 faces the positioning rod 31, and the fixed electromagnet 223 originally facing upward faces downward, that is, the metal sleeve is vertically downward and inserted on the positioning rod 31. During this process, the metal sleeve continues to move downward. When the metal sleeve abuts against the abutment rod 32, the spring of the torsion spring 321 is overcome, and the abutment rod 32 is driven to move in the direction of the positioning rod 31, so that a plurality of abutment rods 32 gradually shrink until a plurality of abutment rods 32 are received in the metal sleeve. At this time, a plurality of abutment rods 32 are supported on the inner wall of the metal sleeve under the action of the torsion spring 321, that is, the abutment rod 32 applies a tightening force to the inner wall of the metal sleeve, thereby fixing the metal sleeve and realizing the positioning of the metal sleeve on the working frame 10. The contraction degree of the abutment rod 32 can be changed, so that metal sleeves with different diameters can be fixed, which has better applicability.

[0041] Reference Figure 1 and Figure 4 , wherein the grinding assembly 40 includes a moving cylinder 41 and two grinding wheels 42. The moving cylinder 41 is mounted on the work frame 10 by bolts, and the moving cylinder 41 is located directly above the positioning rod 31, and the output end of the moving cylinder 41 is vertically downward, and a rotating motor 51 is installed. The output end of the rotating motor 51 is also downward, and a mounting block 50 is coaxially fixed thereto. The moving cylinder 41 is used to drive the mounting block 50 to move up and down, and the rotating motor 51 is used to drive the mounting block 50 to rotate.

[0042] Reference Figure 1 and Figure 4 An adjusting assembly 60 is provided on the mounting block 50, and the adjusting assembly 60 includes an adjusting gear 61 and two adjusting racks 62. A motor is embedded in the mounting block 50, and the motor is coaxially fixed with the adjusting gear 61. The adjusting gear 61 is coaxial with the positioning rod 31, and the adjusting rack 62 is slidably connected to the mounting block 50. The two adjusting racks 62 are parallel to each other, and the adjusting gear 61 is located between the two adjusting racks 62, and the adjusting gear 61 is meshed with the adjusting rack 62. A grinding motor 621 is provided on the adjusting rack 62, and the output end of the grinding motor 621 is coaxially fixed with the top end of the grinding wheel 42, and the grinding motor 621 is used to drive the grinding wheel 42 to rotate.

[0043] After the metal sleeve to be processed is fixed on the positioning rod 31, the moving cylinder 41 is started to drive the mounting block 50 to move downward, so that the grinding wheel 42 moves to the side of the metal sleeve to ensure that the grinding wheel 42 covers the entire metal sleeve, and then the adjusting gear 61 is driven to rotate so that the two adjusting racks 62 move at the same time, driving the two grinding wheels 42 to approach each other by the same distance at the same time, until the distance between the two grinding wheels 42 is equal to the diameter of the metal sleeve to be processed, so that the two grinding wheels 42 are both in contact with the side wall of the metal sleeve, and then the rotating motor 51 and the grinding motor 621 are started to realize that the grinding wheel 42 rotates on its own while revolving along the side wall of the metal sleeve, so as to realize the grinding and polishing of the entire circumferential side wall of the metal sleeve.

[0044] By adjusting the rotation of the gear 61, the distance between the two grinding wheels 42 can be adjusted, so that metal sleeves of different diameters can be ground, and the applicability is better. When the grinding wheel 42 abuts against the side wall of the metal sleeve, the rotating motor 51 drives the grinding wheel 42 to revolve around the metal sleeve, and at the same time, the grinding motor 621 is started to drive the grinding wheel 42 to rotate, thereby improving the accuracy and efficiency of the grinding wheel 42 grinding the metal sleeve.

[0045] Reference Figure 1 and Figure 4 A connecting electromagnet 611 is fixed on the adjusting gear 61, and the connecting electromagnet 611 can be attracted to the end of the metal sleeve. After the transfer plate 222 sets the metal sleeve to be processed on the positioning rod 31, the transfer plate 222 is reset immediately, so as not to interfere with the movement of the grinding wheel 42 above the positioning rod 31, and the reset transfer plate 222 receives a new metal sleeve to be processed again.

[0046] When the metal sleeve on the positioning rod 31 is polished, the connecting electromagnet 611 is started to adsorb the metal sleeve upward onto the connecting electromagnet 611, and then the moving cylinder 41 is started to drive the mounting block 50 to move upward, thereby driving the metal sleeve to move upward until it is pulled out of the positioning rod 31 and the metal sleeve is suspended on the positioning rod 31.

[0047] After the transfer plate 222 drives the new metal sleeve to move to the positioning rod 31, the receiving electromagnet 224 originally facing downward on the transfer plate 222 turns upward and aligns with the mounting block 50 above. At this time, the moving cylinder 41 is started, so that the mounting block 50 moves down with the metal sleeve to the receiving electromagnet 224, and then the receiving electromagnet 224 is started and the connecting electromagnet 611 is closed, so that the processed metal sleeve is fixed on the transfer plate 222. Then the transfer motor 221 is started again to drive the transfer plate 222 to reset.

[0048] The reset transfer plate 222 makes the fixed electromagnet 223 face upward again to receive a new metal sleeve. Repeat the above steps to achieve the sequential loading of the metal sleeves to be processed and the synchronous unloading of the processed metal sleeves. In this process, the transfer plate 222 realizes unloading synchronously during the loading process, achieving full-station operation and improving work efficiency.

[0049] Reference Figure 2 The work frame 10 is provided with a collection box 80 with a top opening, and the collection box 80 is located below the transfer plate 222. A buffer plate 90 is provided in the collection box 80, and the buffer plate 90 is located directly below the transfer plate 222. A protective pad 120 is provided on the top wall of the buffer plate 90.

[0050] When the transfer plate 222 drives the processed metal sleeve to reset, and the transfer plate 222 rotates to 90 degrees, the transfer plate 222 is in a vertical state, and the receiving electromagnet 224 is turned off at this time, so that the processed metal sleeve falls from the transfer plate 222 to the collection box 80 for storage under the action of gravity. Therefore, when the transfer plate 222 is reset, the processed metal sleeve gradually changes from an upward state to a downward state, and the material is removed before the transfer plate 222 is reset, so that the transfer plate 222 will not interfere with the pressing of the limit plate 70.

[0051] Reference Figure 2 , wherein a velvet belt 121 is provided on the bottom wall of the protective pad 120, and a hook belt 91 is provided on the side wall of the buffer plate 90 close to the protective pad 120, and the velvet belt 121 fits with the hook belt 91. When the processed metal sleeve falls from the transfer plate 222 into the collection box 80, the metal sleeve will fall onto the buffer plate 90 and be received by the buffer plate 90. The protective pad 120 plays a protective and buffering role, so that when the metal sleeve hits the buffer plate 90, it is not easy to be damaged.

[0052] The metal sleeve will vibrate when it hits the buffer plate 90, so that the debris remaining on the metal sleeve after grinding will be shaken off onto the protective pad 120. When the protective pad 120 is severely worn or has a lot of debris attached to it, the protective pad 120 is moved away from the buffer plate 90 until the velvet belt 121 is separated from the hook belt 91, so that the protective pad 120 is removed. Then, the velvet belt 121 on the new protective pad 120 is fitted with the hook belt 91, so that the new protective pad 120 is installed, and the replacement of the protective pad 120 is completed.

[0053] The implementation principle of the mobile grinding and polishing device for metal sleeves in the embodiment of the present application is as follows: when in use, the transfer plate 222 uses the fixed electromagnet 223 to flip the metal sleeve to be processed onto the positioning rod 31, and then the transfer plate 222 is reset, and the metal sleeve is fixed by the positioning component 30, and then the moving cylinder 41 is started to drive the mounting block 50 to move down, so that the grinding wheel 42 moves to the side of the metal sleeve to ensure that the grinding wheel 42 covers the entire metal sleeve, and then the adjustment component 60 is started to drive the two grinding wheels 42 to approach each other until the grinding The wheel 42 abuts against the side wall of the metal sleeve, and then the rotating motor 51 is started to drive the mounting block 50 to rotate, so that the grinding wheel 42 rotates around the metal sleeve, thereby achieving grinding and polishing of the entire circumferential side wall of the metal sleeve. The operation is convenient. The grinding wheel 42 is relatively long and can cover metal sleeves of different lengths. At the same time, the distance between the two grinding wheels 42 can be changed, that is, it can abut against the side wall of metal sleeves of different diameters, thereby achieving grinding and polishing of metal sleeves of different diameters, and having better applicability.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
