Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a polishing device for the initial processing of cylindrical metal surfaces. Background Technology

[0002] Metalworking, or metal processing for short, refers to the production activities of humans processing materials with metallic properties, which are composed mainly of metallic elements. It is a process technology that processes metal materials into items, parts, and components. When processing cylindrical metals, due to the presence of rust or other adhering substances on their surface, it is necessary to use special sandpaper for initial polishing.

[0003] However, existing polishing equipment uses a metal polishing method where a rotating rod wraps around sandpaper. In actual operation, the rod is prone to plastic deformation after prolonged use, causing the center of mass of the deformed area to deviate from the rotation axis. This eccentricity leads to two main problems: first, the deformed side is subjected to excessive alternating stress during rotation, accelerating fatigue damage; second, the uneven distribution of sandpaper contact pressure in the deformed area directly affects the uniformity of the polished surface. Therefore, this invention provides a polishing device for the initial processing of cylindrical metal surfaces to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a polishing device for the initial processing of cylindrical metal surfaces, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A polishing device for the initial surface finishing of cylindrical metal includes a polishing machine and a metal body. A control console is mounted on one side of the top of the polishing machine, and a enclosure is mounted on the other side of the top of the polishing machine. A clamping assembly for fixing and rotating the metal body is mounted on the side of the top of the polishing machine inside the enclosure.

[0009] As a further embodiment of the present invention, a fixing ring is fixedly connected to the top of the inner wall of the through hole in the transmission channel, and a damping block is installed at the bottom of the fixing ring at the point where the through hole communicates with the storage cylinder. The damping block is elastic.

[0010] As a further embodiment of the present invention, the control component includes a control cylinder and an adjusting rod. Sliding blocks are slidably connected to both ends of the control cylinder. An adjusting rod is fixedly connected to the end of the sliding block away from the control cylinder. A second spring is fixedly connected between the sliding block and the inner wall of the control cylinder. One end of the suspension rope passes through the control box and is tied to the adjusting rod on the side near the storage cylinder. A counterweight is fixedly connected to the two adjusting rods on the other end near the rotating shaft.

[0011] As a further embodiment of the present invention, the control component further includes an elastic block and a pressing plate. The elastic block is fixedly connected to the inner walls on both sides of the transmission channel and is in contact with the sliding block. The pressing plate is slidably connected to both ends of the inner wall of the control cylinder and is in contact with the outer surface of the elastic block.

[0012] As a further embodiment of the present invention, a fixed plate is fixedly connected to the middle of the inner wall of the control cylinder, and multiple rolling channels are fixedly connected to both ends of the fixed plate. The rolling channels are arc-shaped and the arc direction is away from the axis of rotation. Ball bearings are rolledly connected to the inner wall of the rolling channels, and a pressure plate is slidably connected to the inner wall of the rolling channels. A connecting rod is fixedly connected between the pressure plate and the extrusion plate.

[0013] As a further embodiment of the present invention, the adjustment structure includes an adjustment platform, a second motor, and a placement plate. The adjustment platform is fixedly connected to the top outer wall of the polishing machine, the placement plate is slidably connected to the top outer wall of the second motor, the second motor is installed on one side outer wall of the adjustment platform, a lead screw is installed at the output end of the second motor, and an adjustment block is fixedly connected to the middle position of the bottom of the placement plate. The adjustment block is threadedly connected to the outer wall of the lead screw.

[0014] As a further embodiment of the present invention, the drive structure includes a third motor, a second pulley and a first pulley. Mounting brackets are installed at both ends of the top of the placement plate. The rotating shaft is rotatably connected to the inner wall of the mounting bracket, and the first pulley is fixedly connected to one end of the rotating shaft. A third motor is fixedly connected to one side of the top of the placement plate. The second pulley is installed at the output end of the third motor, and a transmission belt is installed between the second pulley and the first pulley.

[0015] As a further embodiment of the present invention, the clamping assembly includes a first motor, a mounting base, a transmission rod, and a clamping member. The mounting base is installed on the inner walls of both sides of the enclosure, the transmission rod is rotatably connected to the inner wall of the mounting base, and the transmission rod is installed at one end of the clamping member. The first motor is installed on the outer wall of the enclosure, and the transmission rod on the side closer to the first motor is installed at the output end of the first motor.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When using this invention, the storage and control components can transfer the counterweight ball on the bent side of the rotating shaft to the storage cylinder on the opposite side of the bend, based on the different centrifugal forces within the counterweight ring when the rotating shaft rotates. This redistributes the mass at the bend of the rotating shaft, keeping the center of mass of the rotating shaft at its axis. This prevents the center of mass at the bend from being misaligned with the axis and continuously subjected to greater stress damage, thus affecting its service life. Furthermore, it avoids different stresses at the bend that would cause different stresses during polishing by the polishing sleeve, thus affecting the polishing effect.

[0018] 2. When using this invention, the position of the counterweight can be adjusted according to the different centrifugal forces generated when the bend rotates, thereby further adjusting the center of gravity of the rotating shaft and avoiding damage to the rotating shaft.

[0019] 3. When using this invention, the fixed ring and damping block can reduce the speed of the counterweight ball rotating in the through hole of the transmission channel, so as to avoid the rotation speed being too fast and failing to fall into the storage cylinder, thus affecting the adjustment of the center of gravity of the rotating shaft.

[0020] 4. When using this invention, the position of the polishing sleeve can be moved through the set adjustment structure, thereby enabling the polishing of metal bodies of different diameters and improving the applicability of the equipment. Attached Figure Description

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Please see Figures 1-4 In this embodiment of the invention, a surface polishing device for the initial processing of cylindrical metal includes a polishing machine 100 and a metal body 200. A control console 110 is installed on one side of the top of the polishing machine 100. A control center is provided inside the control console 110, and a control button is provided on one side of the control console 110. The control button is electrically connected to the control center. A enclosure 120 is installed on the other side of the top of the polishing machine 100. A clamping assembly for fixing the metal body 200 and driving its rotation is installed on the side of the top of the polishing machine 100 located inside the enclosure 120.

[0041] A polishing assembly for processing the metal body 200 is installed on the top of the polishing machine 100, located on the other side inside the enclosure 120. The polishing assembly includes a grinding structure set on the top for polishing. The grinding structure includes a polishing sleeve 400 and a rotating shaft 410. A ring of sandpaper is fitted on the outer wall of the polishing sleeve 400. The rotating shaft 410 is installed on the outer wall of the polishing sleeve 400. First flanges are installed at both ends of the rotating shaft 410. The polishing sleeve 400 is installed between the two first flanges by bolts.

[0042] The polishing assembly also includes an adjustment structure at the bottom for moving the polishing sleeve 400 and a drive structure on one side of the grinding structure for rotating the rotating shaft 410. When polishing is required, the polishing sleeve 400 is moved to the side of the metal body 200 by the adjustment structure, and then the drive structure is activated to rotate the rotating shaft 410 and the polishing sleeve 400 to polish the metal body 200.

[0043] See Figures 5-7 Multiple sets of counterweight rings 500 arranged in a circular pattern are installed on the outer wall of the rotating shaft 410. Multiple counterweight rings 500 at the same height are connected. A storage component for storing counterweights is installed inside the counterweight ring 500. A control box 600 is installed on the inner wall of the bottom of the counterweight ring 500. A control component that distributes the counterweights in the storage component by centrifugal force is installed inside the control box 600. The control component redistributes the counterweights in the storage component by the different centrifugal forces on each side of the rotating shaft 410, keeping the center of mass of the rotating shaft 410 on its axis, and avoiding the center of mass shifting when the rotating shaft 410 rotates, which would cause excessive force on one side and affect the service life of the rotating shaft 410.

[0044] For more details, please refer to Figure 6 The counterweight ring 500 has mating ears 502 installed at both ends. The outer wall of the rotating shaft 410 has multiple sets of circumferentially arranged insertion holes. The counterweight ring 500 has a plug rod 501 that matches the insertion hole on the side near the rotating shaft 410. Specifically, when the counterweight ring 500 needs to be installed, the plug rod 501 on the counterweight ring 500 is inserted into the insertion hole on the rotating shaft 410 to pre-fix the counterweight ring 500. Then, the mating ears 502 on the adjacent counterweight rings 500 are installed with bolts to fix the counterweight ring 500.

[0045] See Figure 7 and Figure 8 The storage component includes a transmission channel 510 and a storage cylinder 520. The transmission channel 510 is installed on the inner wall of the top of the counterweight ring 500. An annular through hole is opened in the transmission channel 510. The through hole on the transmission channel 510 is connected to the through hole in the transmission channel 510 of the adjacent counterweight ring 500. Mounting rings 521 are installed at both ends of the outer wall of the storage cylinder 520. The storage cylinder 520 is installed on the inner wall of the counterweight ring 500 in a circumferential arrangement through the mounting rings 521. The storage cylinder 520 is connected to the through hole on the transmission channel 510. Multiple counterweight balls 525 are placed in the storage cylinder 520. The outer diameter of the counterweight balls 525 is smaller than the inner diameter of the through hole on the transmission channel 510. When the counterweight balls 525 are pressed to the through hole on the transmission channel 510, the rotating shaft 410 rotates, which drives the counterweight balls 525 to rotate in the through hole on the rotating shaft 410 to the storage cylinder 520 on the other side, so that the weight of the counterweight ring 500 can be adjusted.

[0046] The storage assembly also includes a sliding disk 522, a first spring 524, and a lifting rope 531. A fixed disk 523 is fixedly connected to the bottom of the inner wall of the storage cylinder 520. The sliding disk 522 is slidably connected to the top of the inner wall of the storage cylinder 520. A counterweight ball 525 is located at the top of the sliding disk 522. The first spring 524 is fixedly connected between the sliding disk 522 and the fixed disk 523. One end of the lifting rope 531 is fixedly connected to the bottom of the sliding disk 522, and the other end of the lifting rope 531 passes through the fixed disk 523 and exits. When the hoisting rope 531 is reeling in the material storage cylinder 520, it can pull the sliding disc 522 downward. The downward movement of the sliding disc 522 can increase the capacity of the top of the material storage cylinder 520, so that more counterweight balls 525 can be stored. When the hoisting rope 531 is releasing the line, the sliding disc 522 can slide upward within the material storage cylinder 520 under the elastic force of the first spring 524, which can reduce the capacity of the top of the material storage cylinder 520 and push the counterweight balls 525 into the through hole on the transmission channel 510.

[0047] For more details, please refer to Figure 7 Multiple circumferentially arranged steering wheels 530 are fixedly connected to the inner wall of the bottom of the counterweight ring 500. The lifting rope 531 passes around the bottom of the steering wheel 530. Specifically, the lifting rope 531 can turn by passing around the steering wheel 530, so as to avoid the lifting rope 531 tilting inside the storage cylinder 520 and contacting the first spring 524, which would affect the reset effect of the first spring 524.

[0048] See Figure 8 and Figure 9 A fixing ring 511 is fixedly connected to the top of the inner wall of the through hole in the transmission channel 510. A damping block 512 is installed at the bottom of the fixing ring 511 at the connection between the through hole and the storage cylinder 520. The damping block 512 is elastic. When the counterweight ball 525 rotates to the connection between the through hole and the storage cylinder 520, it can contact the damping block 512. The damping block 512 is deformed by the pressure of the counterweight ball 525, which increases the friction between the counterweight ball 525 and reduces the rotation speed of the counterweight ball 525 in the through hole, making it easier for the counterweight ball 525 to fall into the storage cylinder 520 for storage.

[0049] See Figure 10 and Figure 11The control assembly includes a control cylinder 610 and an adjusting rod 611. The control cylinder 610 is hollow and has sliding grooves at both ends. A sliding block 612 is slidably connected to the inner wall of the sliding groove. The adjusting rod 611 is fixedly connected to the end of the sliding block 612 away from the control cylinder 610. A second spring 613 is fixedly connected between the sliding block 612 and the inner wall of the control cylinder 610. The second spring 613 is sleeved on the outer wall of the adjusting rod 611. The sliding block 612 is reset by the elastic force of the second spring 613. One end of the hoisting rope 531 passes through the control box 600 and is tied to the adjusting rod 611 near the side of the storage cylinder 520. The two adjusting rods 611 at the other end are fixedly connected to a counterweight 601 near the rotating shaft 410. When the sliding block 612 slides in the sliding groove, the hoisting rope 531 is wound up and unwound by the movement of the adjusting rod 611, and the distance between the counterweight 601 and the axis of the rotating shaft 410 is adjusted by the movement of the adjusting rod 611.

[0050] The control assembly also includes an elastic block 614 and a pressing plate 615. The elastic block 614 is fixedly connected to the inner walls on both sides of the transmission channel 510 and is in contact with the sliding block 612. The pressing plate 615 is slidably connected to both ends of the inner wall of the control cylinder 610 and is in contact with the outer surface of the elastic block 614. When the pressing plate 615 is pressed, the elastic block 614 is deformed by the pressure of the pressing plate 615 and enters the sliding groove to press the sliding block 612. The sliding block 612 slides in the sliding groove under the pressure. (The elastic block 614 is axially controlled by the double limiting structure of the control cylinder 610 and the pressing plate 615. The elastic block 614 is circumferentially constrained by the cylinder wall of the control cylinder 610. The two ends of the outer wall of the elastic block 614 can compensate for displacement along the axial direction of the sliding groove. When the elastic block 614 is pressed, it can deform along the axial direction of the sliding groove.)

[0051] See Figure 12 A fixed plate 616 is fixedly connected to the middle of the inner wall of the control cylinder 610. Multiple rolling channels 620 are fixedly connected to both ends of the fixed plate 616. The rolling channels 620 are arc-shaped and the arc direction is away from the axis of the rotating shaft 410. Rolling balls 621 are rolledly connected to the inner wall of the rolling channels 620, and a pressure plate 622 is slidably connected to the inner wall of the rolling channels 620. A connecting rod 623 is fixedly connected between the pressure plate 622 and the extrusion plate 615. When the rotating shaft 410 rotates, the counterweight ring 500 rotates synchronously with the polishing sleeve 400. Under the centrifugal force of rotation, the rolling balls 621 roll away from the axis of the rotating shaft 410. The rolling balls 621 can roll along the arc surface of the rolling channel 620 to the pressure plate 622 and squeeze the pressure plate 622. The pressure plate 622 is squeezed and the pressure is transmitted to the extrusion plate 615 through the connecting rod 623.

[0052] See Figure 3The adjustment structure includes an adjustment platform 300, a second motor 310, and a placement plate 330. The adjustment platform 300 is fixedly connected to the top outer wall of the polishing machine 100. The placement plate 330 is slidably connected to the top outer wall of the second motor 310. The second motor 310 is installed on one side of the outer wall of the adjustment platform 300. The second motor 310 is connected to the control center circuit on the control console 110. A lead screw 311 is installed at the output end of the second motor 310, and a second bearing is installed at the other end of the lead screw 311. The lead screw 311 is rotatably connected to the adjustment platform through the second bearing. An adjusting block 332 is fixedly connected to the bottom center of the placement plate 330 on one side of the inner wall of 300. The adjusting block 332 is threaded to the outer wall of the lead screw 311. When it is necessary to move the placement plate 330, the second motor 310 is started through the control center. The second motor 310 drives the lead screw 311 to rotate. The rotation of the lead screw 311 drives the threaded adjusting block 332 to move, which in turn drives the placement plate 330 to slide on the top of the adjusting table 300. The movement of the placement plate 330 can drive the polishing sleeve 400 to approach the metal body 200.

[0053] More specifically, the top of the adjusting table 300 has slots at both ends, and guide rods 320 are fixedly connected to the inner walls of the slots. Guide blocks 331 are fixedly connected to both ends of the bottom of the placement plate 330. The guide blocks 331 are slidably connected to the outer wall of the guide rods 320. Specifically, the movement of the placement plate 330 can be limited by the sliding of the guide blocks 331 on the outer wall of the guide rods 320, and the adjusting block 332 is prevented from deflecting when the lead screw 311 rotates, which would affect the stability of the movement of the placement plate 330.

[0054] See Figure 4 The drive structure includes a third motor 420, a second pulley 421, and a first pulley 412. Mounting brackets 411 are installed at both ends of the top of the placement plate 330. A rotating shaft 410 is rotatably connected to the inner wall of the mounting bracket 411, and the first pulley 412 is fixedly connected to one end of the rotating shaft 410. A third motor 420 is fixedly connected to one side of the top of the placement plate 330. The third motor 420 is connected to the control center circuit on the control console 110. The second pulley 421 is installed at the output end of the third motor 420. A transmission belt 422 is installed between the second pulley 421 and the first pulley 412. When it is necessary to drive the polishing sleeve 400 to rotate, the third motor 420 is activated through the control center. The third motor 420 drives the second pulley 421 to rotate, and the second pulley 421 drives the first pulley 412 to rotate via the transmission belt 422. The rotation of the first pulley 412 drives the polishing sleeve 400 to rotate via the rotating shaft 410 to polish the metal body 200.

[0055] See Figure 2The clamping assembly includes a first motor 210, a mounting base 220, a transmission rod 221, and a clamping member 230. The mounting base 220 is installed on the inner walls of both sides of the enclosure 120. A second bearing is installed on the outer wall of the transmission rod 221, and the transmission rod 221 is rotatably connected to the inner wall of the mounting base 220 through the second bearing. A second flange is installed on the end of the transmission rod 221 away from the mounting base 220, and the transmission rod 221 is installed on one end of the clamping member 230 through the second flange. The first motor 210 is installed on the outer wall of the enclosure 120, and the transmission rod 221 on the side closest to the first motor 210 is installed at the output end of the first motor 210. The machine 210 is connected to the control center circuit on the console 110. The clamping member 230 is existing technology and will not be described in detail here. The metal body 200 is clamped between the two clamping members 230. When polishing is required, the control button is pressed and the first motor 210 is started through the control center. The first motor 210 can drive the clamping member 230 to rotate through the transmission rod 221, thereby driving the metal body 200 clamped on the clamping member 230 to rotate. The rotation direction of the metal body 200 is opposite to the rotation direction of the polishing sleeve 400. The metal body 200 can be polished by the relative rotation of the two.

[0056] The working principle of this invention is as follows: When polishing is required, the metal body 200 is fixed between two clamping members 230, and the second motor 310 and the third motor 420 are started through the control center. The second motor 310 drives the threaded adjustment block 332 to move through the lead screw 311. The movement of the adjustment block 332 drives the polishing sleeve 400 to move to the outer wall of the metal body 200 through the placement plate 330. The third motor 420 drives the first pulley 412 and the rotating shaft 410 to rotate through the second pulley 421 and the transmission belt 422. The rotation of the rotating shaft 410 drives the polishing sleeve 400 to rotate and polish the outer wall of the metal body 200. Then, the first motor 210 is started through the control center. The first motor 210 drives the clamping member 230 to rotate through the transmission rod 221. The metal body 200 rotates with the clamping member 230 to polish all parts of the outer wall of the metal body 200.

[0057] When the rotating shaft 410 bends, the distance between the bent side and the axis of the rotating shaft 410 increases, and the centrifugal force increases. The ball 621 rolls in the rolling channel 620 with the centrifugal force, squeezing the pressure plate 622. The pressure is transmitted to the elastic block 614 through the connecting rod 623 and the squeezing plate 615. The elastic block 614 is squeezed and deformed, squeezing the sliding block 612. The adjusting rods 611 at both ends move away from the control cylinder 610. The counterweight 601 moves with the adjusting rod 611 towards the axis of the rotating shaft 410. The hanging rope 531 moves with the adjusting rod 611 to release the line. The sliding disk 522 moves upward under the elastic force of the first spring 524, squeezing the counterweight ball 525 into the through hole of the transmission channel 510. The transmission channel 510 rotates with the rotating shaft 410, rotating the counterweight ball 525 in the through hole to the other side.

[0058] At the same time, the distance between the opposite side of the bend and the axis of rotation 410 decreases, the centrifugal force decreases, the counterweight 601 moves away from the axis of rotation 410, the suspension rope 531 is wound up, and the sliding disc 522 is pulled by the suspension rope 531 to increase the accommodating space at the top of the storage cylinder 520, so that the counterweight ball 525 in the through hole can fall into the storage cylinder 520 on that side for storage.

[0059] When this invention is used, the storage and control components can be configured to transfer the counterweight ball 525 on the bent side of the rotating shaft 410 to the storage cylinder 520 on the opposite side of the bend, based on the different centrifugal forces within the counterweight ring 500 when the rotating shaft 410 rotates. This redistributes the mass at the bend of the rotating shaft 410, keeping the center of mass of the rotating shaft 410 at its axis. This prevents the center of mass at the bend from being misaligned with the axis and continuously subjected to greater stress damage, thus affecting its service life. Furthermore, it avoids the different stresses at the bend from causing different stresses during polishing by the polishing sleeve 400, which would affect the polishing effect.

[0060] By setting the counterweight 601, the position of the counterweight 601 can be adjusted according to the different centrifugal forces generated when the bend rotates, and the center of mass of the rotating shaft 410 can be further adjusted to avoid damage to the rotating shaft 410.

[0061] By using the fixed ring 511 and damping block 512, the rotation speed of the counterweight ball 525 in the through hole of the transmission channel 510 can be reduced, so as to avoid the rotation speed being too fast and failing to fall into the storage cylinder 520, thus affecting the adjustment of the center of mass of the rotating shaft 410.

[0062] The adjustable structure allows the polishing sleeve 400 to be moved, enabling the polishing of metal bodies 200 of different diameters and improving the applicability of the equipment.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
