[0032] A multifunctional mechatronic polishing machine comprises a mounting frame 101 and a mounting plate 102, wherein the mounting plate 102 is transversely fixed on the top of the mounting frame 101, and the mounting frame 101 and the mounting plate 102 together constitute an operating platform, a motor support frame 103 is vertically fixedly welded to one side of the upper surface of the mounting plate 102, a grinding drive motor 104 is fixedly installed on the top of the motor support frame 103 by screws, and the grinding drive motor 104 is a dual-output shaft motor, and one output shaft of the grinding drive motor 104 is fixedly installed with a first grinding wheel 105 through a chuck, and a first grinding wheel 105 is rotatably installed at the inner edge of the first grinding wheel Four grinding blocks 106, the four grinding blocks 106 are evenly distributed at the edge of the first grinding wheel 105, the outer surface of the grinding block 106 is flush with the outer surface of the first grinding wheel 105, one end of the grinding block 106 is rotatably connected to the inner wall of the first grinding wheel 105 through a rotating shaft, the grinding block 106 is used to grind the inner wall of the pipeline, the other end of the grinding block 106 is fixedly connected to the side surface of a return spring 107, the other end of the return spring 107 is fixedly connected to the inner wall of the first grinding wheel 105, and the return spring 107 is used to pull the free end of the grinding block 106 toward the first grinding wheel 105;

[0033] The chuck used to connect the grinding drive motor 104 and the first grinding wheel 105 is composed of a metal disc welded on the output shaft of the grinding drive motor 104 and four fixing bolts thereon. The user can fix the first grinding wheel 105 on the metal disc through the four fixing bolts. This connection method is more stable than the traditional single screw hole installation method, and can effectively avoid the phenomenon of idling of the first grinding wheel 105 due to loose bolts.

[0034] The diameter of the first grinding wheel 105 can be determined according to the inner diameter of the metal tube to be ground. It is only necessary to select a first grinding wheel 105 with a diameter slightly smaller than the inner diameter of the metal tube. Since the grinding block 106 can fly out of the first grinding wheel 105 to grind the inner wall of the metal tube during operation, the first grinding wheel 105 with a smaller diameter can also grind the inner wall of the metal tube with a larger diameter.

[0035] The present invention arranges a grinding block 106 with one end that can rotate freely inside the first grinding wheel 105, so that when the first grinding wheel 105 rotates at a high speed, the free end of the grinding block 106 will fly out of the outer wall of the first grinding wheel 105, thereby being able to grind the curved inner wall of the metal circular tube, and the grinding force can also be adaptively changed by changing the rotation speed of the first grinding wheel 105. Therefore, the device has a higher efficiency in grinding the curved inner wall of the metal circular tube and is suitable for large-scale key inner wall grinding.

[0036] Further, an adjusting shaft 201 is inserted at the center of one side of the first grinding wheel 105, and four L-shaped clamping rods 203 are evenly welded around one end of the adjusting shaft 201 located inside the first grinding wheel 105. A clamping groove 204 is fixedly opened on the side of one end of the grinding block 106 connected to the reset spring 107, and the L-shaped clamping rod 203 cooperates with the clamping groove 204. The adjusting shaft 201 is used to screw the L-shaped clamping rod 203 into or out of the clamping groove 204. A first adjusting dial 202 is fixedly welded at one end of the adjusting shaft 201 located outside the first grinding wheel 105, and the first adjusting dial 202 is used to drive the adjusting shaft 201 to rotate;

[0037] When in use, when the grinding block 106 is needed to grind the inner wall of the metal round tube, the user can rotate the adjustment shaft 201 through the first adjustment dial 202, so that the adjustment shaft 201 can drive the L-shaped clamping rod 203 thereon to rotate, so that the L-shaped clamping rod 203 is disengaged from the clamping groove 204. When the L-shaped clamping rod 203 cannot limit the grinding block 106 by the clamping groove 204, the high-speed rotation of the first grinding wheel 105 will throw the free end of the grinding block 106 out, thereby achieving the grinding of the inner wall of the metal round tube. Grinding; when the user does not need to grind the inner wall of the metal round tube, the user can rotate the adjusting shaft 201 through the first adjusting dial 202, so that the adjusting shaft 201 can drive the L-shaped clamping rod 203 thereon to rotate, and let the L-shaped clamping rod 203 enter the clamping groove 204, and the L-shaped clamping rod 203 can be effectively used to limit the free end of the grinding block 106. When the first grinding wheel 105 rotates at a high speed, since the grinding block 106 is limited, its free end will not be thrown out of the first grinding wheel 105.

[0038] Further, a telescopic rod 301 is fixedly installed on the upper surface of the mounting plate 102, and the telescopic rod 301 is arranged on one side of the motor support frame 103. A pipe limiting mechanism 302 is fixedly installed on the top telescopic end of the telescopic rod 301, and the pipe limiting mechanism 302 is an adjustable limiting mechanism. The pipe limiting mechanism 302 is arranged corresponding to the first grinding wheel 105, and the pipe limiting mechanism 302 is used to limit the pipe to be ground on the first grinding wheel 105;

[0039] The telescopic rod 301 is used to adapt to metal round tubes of different diameters. Since the center of the first grinding wheel 105 is kept at the same height and does not change, and the pipe limiting mechanism 302 causes the center of the metal round tube to not correspond to the first grinding wheel 105 when limiting metal round tubes of different diameters, the telescopic rod 301 is provided for adjustment.

[0040] Among them, the adjustment function of the pipe limiting mechanism 302 can be achieved by vertically setting an adjustment bolt on its upper part, that is, an extra-long bolt is vertically threadedly installed on the top of the pipe limiting mechanism 302, and the effect of limiting metal pipes of different diameters can be achieved by changing the screw-in depth of the bolt.

[0041] Further, a grinding groove 401 is provided at the center of the mounting plate 102, two slide rails 403 are transversely provided inside the grinding groove 401, two ends of the two slide rails 403 are respectively fixedly connected to the mounting frame 101, threaded rods 402 are provided in parallel at the centers of the two slide rails 403, two ends of the threaded rods 402 are rotatably connected to the mounting frame 101 through bearings, a slider 404 is installed on the threaded rods 402 and the slide rails 403, two through holes 406 are provided on the side of the slider 404, a threaded hole 405 is provided on the slider 404 between the two through holes 406, the slider 404 is slidably provided on the slide rail 403 through the two through holes 406, the threaded rod 402 is threadedly connected to the slider 404 through the threaded hole 405, and the threaded rod 402 is used to drive the slider 404 to slide on the slide rail 403;

[0042] When polishing the surface of a flat metal, the metal can be placed on the slider 404, and then the slider 404 carrying the metal to be polished can be slowly pushed to the bottom of the first grinding wheel 105 by rotating the threaded rod 402, so that the first grinding wheel 105 can polish the upper surface of the metal. After the polishing is completed, the slider 404 carrying the polished metal can be pulled out from under the first grinding wheel 105 by rotating the threaded rod 402, so as to facilitate the removal of the polished workpiece.

[0043] Furthermore, two scissor arm structures 501 are fixedly installed in parallel on the upper surface of the slider 404, and the scissor arm structures 501 are used to lift the workpiece to be ground to the bottom of the first grinding wheel 105. The first pulley 503 and the second pulley 502 are fixedly installed at the ends of the driving shafts of the two scissor arm structures 501, respectively. The first pulley 503 and the second pulley 502 are respectively used to drive the two scissor arm structures 501 to rise and fall, and a crank 505 is fixedly welded on the side of the first pulley 503, and the crank 505 is used to drive the first pulley 503 to rotate. The first pulley 503 and the second pulley 502 are jointly provided with a transmission belt 504, and the transmission belt 504 is used to transmit the power of the first pulley 503 to the second pulley 502;

[0044] Among them, since the heights of the metal workpieces to be plane-grinded are inconsistent, two identical scissor arm structures 501 are set to lift the metal workpiece to a height that can contact the first grinding wheel 105. In order to make the two scissor arm structures 501 lift the metal workpiece to the same height and avoid tilting of the workpiece, a first pulley 503, a second pulley 502 and a transmission belt 504 are set, which can enable the lifting action of the two scissor arm structures 501 to be performed simultaneously, ensuring that the workpiece remains in a horizontal state during the lifting process.

[0045] Furthermore, a workpiece clamping platform 601 is commonly provided on the top of the two scissor arm structures 501, a workpiece clamping portion 602 is provided on the side of the workpiece clamping platform 601, two clamping slide bars 603 are horizontally fixedly welded on the side of the workpiece clamping portion 602, the other end of the clamping slide bar 603 passes through the workpiece clamping platform 601, a stopper 605 is fixedly welded on one end of the clamping slide bar 603 located inside the workpiece clamping platform 601, a section of the clamping slide bar 603 located inside the workpiece clamping platform 601 is sleeved with a resistance spring 604, and the stopper 605 is used to prevent the resistance spring 604 from falling off the clamping slide bar 603;

[0046] The workpiece clamping platform 601 is provided to ensure that the metal workpiece does not move during the grinding process, so as to achieve better clamping of the workpiece.

[0047] Furthermore, a second adjusting dial 701 is fixedly welded to one end of the threaded rod 402 located outside the mounting frame 101, and an adjusting drive motor 702 is provided at the other end of the threaded rod 402. The power output end of the adjusting drive motor 702 is fixedly connected to the threaded rod 402, and the adjusting drive motor 702 is fixedly mounted on the outer wall of the mounting frame 101 by screws;

[0048] Among them, by respectively arranging a second adjusting dial 701 and an adjusting drive motor 702 at both ends of the threaded rod 402, the adjusting drive motor 702 can be used to quickly drive the threaded rod 402 to rotate in the initial stage, so that the slider 404 with the metal workpiece to be polished can be quickly moved to the bottom of the first grinding wheel 105, and then the second adjusting dial 701 is manually controlled to slowly move the slider 404, so as to finely polish the metal workpiece on the slider 404.

[0049] Further, an adjusting slot 801 is vertically penetrated on the surface of the mounting plate 102, and the adjusting slot 801 and the grinding slot 401 are arranged parallel to each other, and an adjusting block 803 is slidably installed inside the adjusting slot 801, and a roller support frame 804 is fixedly welded on the upper surface of the adjusting block 803, and a driven roller 805 is rotatably installed on the top of the roller support frame 804, and the driven roller 805 and the first grinding wheel 105 are arranged in the same plane, and the first grinding wheel 105 and the driven roller 805 are both sleeved with a flexible grinding belt 806, and the flexible grinding belt 806 is used for grinding large-area workpieces;

[0050] The flexible grinding belt 806 may be a sandpaper ring after anti-fracture reinforcement treatment, or other flexible grinding materials;

[0051] By setting the driven roller 805, after the flexible grinding belt 806 is sleeved on the first grinding wheel 105 and the driven roller 805, the driven roller 805 can be used to tension the flexible grinding belt 806 so that the flexible grinding belt 806 can better grind the plane of the metal workpiece.

[0052] Furthermore, the upper surface of the mounting plate 102 is provided with limit racks 802 on both sides of the adjusting slot 801, and a pawl 807 is rotatably installed on the side of the adjusting block 803. The pawl 807 cooperates with the limit rack 802, and the pawl 807 is used to limit the position of the adjusting block 803 on the adjusting slot 801;

[0053] Among them, the pawl 807 is rotatably installed on the adjusting block 803, and a torsion spring is installed at the connection between the pawl 807 and the adjusting block 803, which can always push the bottom of the pawl 807 toward the limiting rack 802. In this way, when in use, the user first puts the flexible grinding belt 806 on the first grinding wheel 105 and the driven roller 805, and then pushes the adjusting block 803 backward. When the flexible grinding belt 806 is tensioned, the pawl 807 will be stuck in the corresponding position of the limiting rack 802, thereby preventing the adjusting block 803 from moving back, and then keeping the flexible grinding belt 806 in a tensioned state.

[0054] Furthermore, another output shaft of the grinding drive motor 104 is fixedly mounted with a second grinding wheel 901 via a chuck, and the second grinding wheel 901 and the first grinding wheel 105 are symmetrically arranged with respect to the grinding drive motor 104, so as to facilitate fine manual grinding of the workpiece using the second grinding wheel 901.

[0055] In summary:

[0056] When in use, when the grinding block 106 is needed to grind the inner wall of the metal round tube, the user can rotate the adjusting shaft 201 through the first adjusting dial 202, so that the adjusting shaft 201 can drive the L-shaped clamping rod 203 thereon to rotate, so that the L-shaped clamping rod 203 is disengaged from the clamping groove 204. When the L-shaped clamping rod 203 cannot limit the grinding block 106 by the clamping groove 204, the high-speed rotation of the first grinding wheel 105 will throw out the free end of the grinding block 106, thereby achieving the grinding of the inner wall of the metal round tube; and when the user does not need to grind the inner wall of the metal round tube, the user can use The user can rotate the adjustment shaft 201 through the first adjustment dial 202, so that the adjustment shaft 201 can drive the L-shaped clamping rod 203 thereon to rotate, so that the L-shaped clamping rod 203 enters the clamping groove 204, and the L-shaped clamping rod 203 can be effectively used to limit the free end of the grinding block 106. When the first grinding wheel 105 rotates at a high speed, since the grinding block 106 is limited, its free end will not be thrown out of the first grinding wheel 105, so that the flexible grinding belt 806 can be simultaneously sleeved on the first grinding wheel 105 and the driven roller 805 to achieve polishing and grinding of the flat surface of the metal workpiece;

[0057] The present invention arranges a grinding block 106 with one end that can rotate freely inside the first grinding wheel 105, so that when the first grinding wheel 105 rotates at a high speed, the free end of the grinding block 106 will fly out of the outer wall of the first grinding wheel 105, thereby being able to grind the curved inner wall of the metal circular tube, and the grinding force can also be adaptively changed by changing the rotation speed of the first grinding wheel 105. Therefore, the device has a higher efficiency in grinding the curved inner wall of the metal circular tube and is suitable for large-scale key inner wall grinding.
