[0001] The invention relates to the technical field of spherical surface polishing, in particular to a concave-convex spherical surface polishing integrated device. Background Art

[0002] Concave and convex spherical polishing can significantly reduce the roughness of the workpiece surface, making it smooth or even mirror-like, thereby meeting specific appearance or functional requirements; it can improve the corrosion resistance and wear resistance of the workpiece surface, reduce the resistance to plastic flow, improve the accuracy of the mold surface, prevent flashing and other problems, and thus improve the overall performance and service life of the product.

[0003] The polishing of concave and convex spherical workpieces requires polishing the concave surface and the convex surface in sequence to ensure the smoothness and consistency of the entire workpiece surface. For example, Chinese patent number CN109352470A discloses a curved surface polishing machine, which can polish the curved surface of the side of the workpiece separately by controlling the rotation of the workpiece and coordinating the continuous movement of the processing devices set on both sides of the workpiece for polishing.

[0004] Traditional equipment often has many inconveniences and limitations in the polishing of concave and convex spherical workpieces. First, it is difficult to flexibly switch between the various polishing steps of concave and convex workpieces in the steps of polishing the concave and convex surfaces in sequence. In addition, the centering process of the workpiece before polishing is complicated and the accuracy is difficult to guarantee, which directly affects the subsequent polishing quality and effect. Summary of the invention

[0006] The technical solution of the present invention for solving the above-mentioned technical problems is as follows: a concave and convex spherical surface polishing integrated equipment, including a workbench and a manipulator, the top of the workbench is fixedly connected to an L-shaped plate, and the top of the L-shaped plate is rotatably connected to a metal ball through a rotating mechanism, the side walls of the metal ball are provided with arc grooves, and the side walls of the metal ball are fixedly inserted with electromagnets, the manipulator is fixedly connected to a mounting plate, and the top of the mounting plate is fixedly connected to two symmetrically arranged first motors, the output ends of each of the first motors are fixedly connected to a connecting shaft, and the lower ends of each connecting shaft are connected to a moving rod through a pressure control mechanism, the lower end of one of the moving rods is fixedly connected to a concave spherical grinding disk, and the lower end of the other moving rod is fixedly connected to a convex spherical grinding disk, and the bottom of the mounting plate is provided with a centering mechanism for centering the workpiece.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the rotating mechanism includes two symmetrically arranged fixed plates fixedly connected to the top of the L-shaped plate, and the metal ball is rotatably connected to the side walls of the fixed plates through a rotating shaft, wherein a second motor is fixedly connected to the side walls of one of the fixed plates, and the output end of the second motor is fixed to one end of the rotating shaft.

[0009] The beneficial effect of adopting the above further solution is that when the second motor is started, the rotation of the second motor drives the rotation of the shaft, which in turn drives the metal ball to rotate, thereby rotating the metal ball 180 degrees.

[0010] Furthermore, the centering mechanism includes a first moving block, and the bottom of the first moving block is fixedly connected to a connecting rod, the lower end of the connecting rod is fixedly connected to a ball, and a telescopic mechanism is arranged between the first moving block and the mounting plate, and the bottom of the mounting plate is provided with a limiting mechanism for limiting the first moving block.

[0011] The beneficial effect of adopting the above further scheme is that the mounting plate is moved by the robot arm so that the sphere and the metal ball are concentric in the vertical direction, and then the mounting plate is moved downward. When the sphere abuts against the top of the workpiece, the workpiece can be centered.

[0012] Furthermore, the telescopic mechanism includes two symmetrically arranged first sleeves fixedly connected to the bottom of the mounting plate, and each first sleeve is inserted with a first rod, the lower end of the first rod is fixed to the top of the first moving block, and the side wall of each first sleeve is sleeved with a second spring.

[0013] The beneficial effect of adopting the above further solution is that when the mounting plate continues to move downward, the second spring is gradually compressed, so that the distance between the first moving block and the mounting plate gradually decreases, and the first moving block is limited by the limiting mechanism.

[0014] Furthermore, the pressure control mechanism includes a fixed tube fixedly connected to the bottom of each connecting shaft, and a first sliding disk is slidably connected in the fixed tube, the upper end of the moving rod is inserted in the fixed tube and fixed to the bottom of the first sliding disk, and a connecting tube is fixedly connected to the side wall of the fixed tube, a second sliding disk is connected to the connecting tube through a moving mechanism, and an end of the second sliding disk is connected to a piston through a telescopic assembly, a distance sensor is fixedly inserted at the end of the second sliding disk, and the fixed tube and the connecting tube are filled with hydraulic oil.

[0015] The beneficial effect of adopting the above further scheme is that when polishing is performed, when the concave spherical grinding disc or the convex spherical grinding disc is polishing the concave and convex spherical surface of the workpiece, when the concave spherical grinding disc or the convex spherical grinding disc is against the polishing surface of the workpiece, the first sliding disc can be pushed upward by the moving rod, thereby squeezing the internal hydraulic oil and pushing the piston to move in the direction close to the second sliding disc. The change in the piston distance is detected by the distance sensor, and the extrusion force during polishing is determined, thereby ensuring that the pressure during polishing is within the required range.

[0016] Furthermore, the telescopic assembly includes a second rod fixedly connected to the end of the second sliding disk, and the side wall of each second rod is sleeved with a second sleeve, the other end of the second sleeve is fixed to the end of the piston, and the side wall of each second sleeve is sleeved with a third spring.

[0017] The beneficial effect of adopting the above further scheme is that the internal hydraulic oil can be squeezed and the piston can be pushed to move towards the second sliding disk. At the same time, the third spring is compressed. At this time, the change in the piston distance is detected by the distance sensor to determine the compression amount of the third spring, and then determine the extrusion force during polishing.

[0018] Further, the moving mechanism includes a first L-shaped block and a second L-shaped block fixedly connected to the end of the connecting pipe, and the side wall of the first L-shaped block is fixedly connected to a third sleeve rod, the side wall of the third sleeve rod is sleeved with a third sleeve, and the other end of the third sleeve is fixed to the end of the second sliding disk, the side wall of the second L-shaped block is rotatably connected to a threaded rod, and the side wall of the threaded rod is threadedly connected to a threaded tube, the other end of the threaded tube is fixed to the end of the second sliding disk, the side wall of the second L-shaped block is fixedly connected to a third motor, and the output end of the third motor is fixed to one end of the threaded rod.

[0019] The beneficial effect of adopting the above further scheme is that when the pressure is too high, the third motor can be started. The rotation of the third motor drives the rotation of the threaded rod, which can drive the second sliding disk to move in the direction close to the first L-shaped block, thereby performing pressure relief protection, ensuring the polishing effect while avoiding damage to the workpiece due to excessive pressure.

[0020] Furthermore, the limiting mechanism includes a third L-shaped block fixedly connected to the bottom of the mounting plate, and the side wall of the third L-shaped block is fixedly connected to a fixed cover, a sliding plate is slidably connected inside the fixed cover via a reset mechanism, and the side wall of the sliding plate is fixedly connected to a plurality of triangular blocks arranged in an array, the triangular blocks include an inclined surface and a limiting surface, and the movement of the sliding plate is pushed by a pushing mechanism.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that when the mounting plate moves, the fixed cover is driven to move by the third L-shaped block, so that the second moving block is separated from the pushing plate. At this time, the sliding plate can be reset in the direction away from the fixed cover under the action of the resetting mechanism, and drive the triangular block to extend outward. When the mounting plate continues to move downward, the second spring is gradually compressed, so that the distance between the first moving block and the mounting plate gradually becomes smaller. When the first moving block abuts against the inclined surface, it can push the triangular block and the sliding plate to move into the fixed cover. When the mounting plate stops moving downward, the sliding plate can extend outward under the action of the resetting mechanism, and make the limiting surface abut against the side wall of the first moving block, thereby limiting the first moving block.

[0022] Furthermore, the reset mechanism includes a fourth spring fixedly connected to the side wall of the sliding plate, and the other end of the fourth spring is fixed to the inner side wall of the fixed cover.

[0023] The beneficial effect of adopting the above further solution is that it plays a guiding and resetting role in the movement of the sliding plate.

[0024] Furthermore, the pushing mechanism includes a strip opening opened at the top of the fixed cover, and a second moving block is inserted in the strip opening, the second moving block is fixed to the top of the sliding plate, the top of the workbench is fixedly connected to the support plate, and the side wall of the support plate is fixedly connected to the pushing plate.

[0025] The beneficial effect of adopting the above further scheme is that after polishing is completed, the mounting plate is driven by the robot to move and reset. When the push plate abuts against the side wall of the second moving block, the sliding plate is pushed to slide into the fixed cover. At the same time, the fourth spring is compressed. At this time, the triangular block retracts into the fixed cover and disengages from the first moving block. The first moving block can move downward and reset under the action of the second spring.

[0026] The beneficial effects of the present invention are:

[0027] 1) By placing the workpiece on a rotatable metal ball and using an electromagnet to fix it, the workpiece can be easily switched from the concave surface to the convex surface. This design not only simplifies the workpiece replacement steps during the polishing process, but also improves the polishing efficiency. When the convex surface of the workpiece needs to be polished, just rotate the metal ball 180 degrees and re-place the workpiece on the metal ball without repositioning or adjusting the polishing equipment, which greatly saves time and manpower.

[0028] 2) By setting a rotating mechanism and a centering mechanism, when it is necessary to polish the concave spherical surface of the workpiece, the workpiece is placed on the arc groove, and then the mounting plate is moved by the manipulator so that the sphere and the metal ball are concentric in the vertical direction. When the mounting plate moves, the fixed cover is driven to move by the third L-shaped block, so that the second moving block is separated from the pushing plate. At this time, the sliding plate can be moved and reset in the direction away from the fixed cover under the action of the fourth spring, and drive the triangular block to extend outward, and then the mounting plate is moved downward. When the sphere abuts against the top of the workpiece, the workpiece can be centered. After the centering adjustment is completed, the electromagnet is energized so that the metal ball adsorbs the workpiece, thereby ensuring the quality of subsequent polishing. When the mounting plate continues to move downward, the second spring is gradually compressed, so that the distance between the first moving block and the mounting plate gradually becomes smaller. When the first moving block abuts against the inclined surface, the triangular block and the sliding plate can be pushed to move into the fixed cover. At the same time, the fourth spring is compressed. When the mounting plate stops moving downward, the sliding plate can The first movable block can be moved downward and reset under the action of the second spring. When the convex spherical surface of the workpiece needs to be polished, the electromagnet is first powered off and the workpiece is removed. Then, the second motor is started. The rotation of the second motor drives the rotation of the rotating shaft, and then drives the metal ball to rotate, thereby rotating the metal ball 180 degrees. Then, the workpiece is sleeved on the side wall of the metal ball. Then, the workpiece can be fixed in the center and polished by the convex spherical grinding disc. This makes it easier to polish the concave and convex spherical surfaces of the workpiece, and the use is more convenient and quick.

[0029] 3) By setting a pressure control mechanism, etc., during polishing, when the concave spherical grinding disc or the convex spherical grinding disc is polishing the concave and convex spherical surface of the workpiece, when the concave spherical grinding disc or the convex spherical grinding disc is against the polishing surface of the workpiece, the first sliding disc can be pushed upward by the moving rod, thereby squeezing the internal hydraulic oil and pushing the piston to move in the direction close to the second sliding disc. At the same time, the third spring is compressed. At this time, the change in the piston distance can be detected by the distance sensor to determine the compression amount of the third spring, and then the squeezing force during polishing can be determined, so as to ensure that the pressure during polishing is within the required range. Moreover, when the pressure is too high, the third motor can be started, and the rotation of the third motor drives the rotation of the threaded rod, which can drive the second sliding disc to move in the direction close to the first L-shaped block, thereby performing pressure relief protection, ensuring the polishing effect while avoiding damage to the workpiece caused by excessive pressure.

[0053] The specific method of use of the present invention is as follows:

[0054] When in use, first, when the concave spherical surface of the workpiece 22 needs to be polished, the workpiece 22 is placed on the arc groove 20, and then the mounting plate 12 is moved by the manipulator 11, so that the ball 303 and the metal ball 19 are concentric in the vertical direction. When the mounting plate 12 moves, the third L-shaped block 501 drives the fixed cover 502 to move, so that the second moving block 602 is separated from the push plate 604. At this time, the sliding plate 503 can be moved and reset in the direction away from the fixed cover 502 under the action of the fourth spring 10, and drive the triangular block 504 to extend outward, and then the mounting plate 12 is moved downward, and when the ball 303 is against the top of the workpiece 22, the workpiece 22 can be adjusted to the center;

[0055] After the centering adjustment is completed, the electromagnet 21 is energized, so that the metal ball 19 adsorbs the workpiece 22, thereby ensuring the quality of subsequent polishing. When the mounting plate 12 continues to move downward, the second spring 403 is gradually compressed, so that the distance between the first moving block 301 and the mounting plate 12 gradually becomes smaller. When the first moving block 301 abuts against the inclined surface 505, it can push the triangular block 504 and the sliding plate 503 to move into the fixed cover 502. At the same time, the fourth spring 10 is compressed. When the mounting plate 12 stops moving downward, the sliding plate 503 can extend outward under the action of the fourth spring 10, and the limiting surface 506 abuts against the side wall of the first moving block 301, so that the first moving block 301 can be limited, ensuring the normal polishing of the concave spherical grinding disc 16 and the convex spherical grinding disc 17. Then, the concave spherical surface is polished by the concave spherical grinding disc 16;

[0056] After polishing is completed, the mounting plate 12 is driven by the manipulator 11 to move and reset. When the pushing plate 604 abuts against the side wall of the second moving block 602, the sliding plate 503 is pushed to slide into the fixed cover 502. At the same time, the fourth spring 10 is compressed. At this time, the triangular block 504 is retracted into the fixed cover 502 and disengaged from the first moving block 301. The first moving block 301 can move downward and reset under the action of the second spring 403. When it is necessary to polish the convex spherical surface of the workpiece 22, the electromagnet 21 is first powered off and the workpiece 22 is removed. Then, the second motor 203 is started. The rotation of the second motor 203 drives the rotation of the rotating shaft 202, and then drives the metal ball 19 to rotate, thereby rotating the metal ball 19 180 degrees. Then, the workpiece 22 is sleeved on the side wall of the metal ball 19. Then, the workpiece 22 can be fixed in the center and polished by the convex spherical grinding disc 17, so as to facilitate the polishing operation of the concave and convex spherical surface of the workpiece 22, which is more convenient and quick to use.

[0057] Furthermore, during polishing, when the concave spherical grinding disc 16 or the convex spherical grinding disc 17 is polishing the concave and convex spherical surface of the workpiece 22, when the concave spherical grinding disc 16 or the convex spherical grinding disc 17 is against the polishing surface of the workpiece 22, the first sliding disc 702 can be pushed upward by the moving rod 15, so that the internal hydraulic oil can be squeezed and the piston 705 can be pushed to move in the direction close to the second sliding disc 704. At the same time, the third spring 803 is compressed. At this time, the change in the distance of the piston 705 can be detected by the distance sensor 706, so that the compression amount of the third spring 803 can be determined, and then the squeezing force during polishing can be determined, so as to ensure that the pressure during polishing is within the required range. Moreover, when the pressure is too high, the third motor 907 can be started, and the rotation of the third motor 907 drives the rotation of the threaded rod 906, which can drive the second sliding disc 704 to move in the direction close to the first L-shaped block 901, so as to perform pressure relief protection, ensure the polishing effect, and avoid damage to the workpiece 22 caused by excessive pressure.

[0058] In summary: The beneficial effects of the present invention are embodied in that it is convenient to center the workpiece 22 to ensure the quality of polishing; it is convenient to control the polishing pressure to ensure the polishing effect while avoiding damage to the workpiece 22 caused by excessive pressure.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
