Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to a polishing device for processing hard alloy materials which is easy to clean. Background Art

[0002] Cemented carbide tubes have the advantages of high hardness, wear resistance, and good toughness. During the processing of cemented carbide tube products, they will be polished to improve the surface quality so that they can better meet the application requirements of high temperature, high pressure, high corrosion and other environments.

[0003] Most of the existing devices cannot adapt well to the polishing of the outer wall and the inner wall of the alloy tube at the same time. It is necessary to replace the device or the clamp to operate separately, which is more troublesome. In addition, during the polishing process, due to the clamping method, dead corners will exist on the outer wall and the inner wall of the alloy tube. This area cannot be polished, resulting in incomplete polishing and difficulty in meeting the needs of the staff. In addition, waste chips will splash and scatter everywhere during the polishing process, making it inconvenient for the staff to clean up. Summary of the invention

[0041] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. Example 1

[0042] Please refer to Figure 1-Figure 16 As shown, a polishing device for processing cemented carbide materials that is easy to clean includes a base 1, and conveyors 101 are arranged on the front and rear sides of the top of the base 1. The conveyor 101 is used to convey the alloy tube 102 to be polished. A waste collection box 103 is arranged on the right side of the top of the base 1, and an electric lifting rod 104 is arranged on the bottom right end of the conveyor 101. The output end of the electric lifting rod 104 is fixedly connected to a support plate 105. The top of the base 1 is connected to two groups of movable seats 106 through a moving mechanism 2 near the right end of the conveyor 101. The top of the movable seat 106 is rotatably connected to a rotating seat 107, and the top of the rotating seat 107 is rotatably connected to a rotating rod 112. A connecting seat 113 is fixedly connected to the rotating rod 112, and the interior of the connecting seat 113 is rotatably connected to a first sleeve 116, and a third driving motor 117 is arranged on the outer side of one group of connecting seats 113. A first sleeve 116 is fixedly connected to the output end of the third driving motor 117, and the outer ring of the first sleeve 116 is provided with a clamping mechanism 3 for fixing the alloy tube 102, and the second sleeve 118 is slidably connected inside the first sleeve 116, and the third sleeve 119 is slidably connected inside the second sleeve 118, and the fourth sleeve 120 is slidably connected inside the third sleeve 119, and the first sleeve 116, the second sleeve 118, the third sleeve 119 and the fourth sleeve 120 are connected by a telescopic mechanism 5, and a kit 121 is welded to the outer end of the fourth sleeve 120, and the outer ring of the kit 121 is rotatably connected to a mounting seat 122, and an internal polishing mechanism 4 is provided inside the mounting seat 122, and the internal polishing mechanism 4 is used to polish the inner wall of the alloy tube 102, and an external polishing mechanism 6 for polishing the outer wall of the alloy tube 102 is also installed on the top right side of the base 1. Example 2

[0043] Please refer to Figure 3 As shown, the moving mechanism 2 includes a fixed block 201, two groups of fixed blocks 201 are fixedly installed on both sides of the top of the base 1, a first screw rod 202 is rotatably connected between the two groups of fixed blocks 201, a movable seat 106 is threadedly connected to the outer surface of the first screw rod 202, and the movable seat 106 is slidably connected to the outer surface of the fixed rod 203, and both ends of the fixed rod 203 are respectively welded to the inner sides of the two groups of fixed blocks 201, and a dual-axis motor 204 is also arranged on the top of the base 1, and the two output ends of the dual-axis motor 204 are respectively fixedly connected to one end of the first screw rod 202 on both sides.

[0044] It is understandable to those skilled in the art that the output end of the dual-axis motor 204 can drive the first screw rod 202 to rotate, so that the movable seat 106 slides back and forth along the outer surface of the fixed rod 203. Since the dual-axis motor 204 has two sets of output ends, the two sets of output ends can be controlled separately. Example 3

[0045] Please refer to Figure 6-Figure 8As shown, the clamping mechanism 3 includes a connecting block 301, a threaded rod 302 and a clamping piece 307. The connecting block 301 is provided with two groups and both are welded to the outer wall of the first sleeve 116. The threaded rod 302 is rotatably connected to the inside of the two groups of connecting blocks 301. A connecting rod 303 is installed between the two groups of connecting blocks 301. Two groups of movable rings 305 are slidably connected to the outer surface of the connecting rod 303. The threads opened at both ends of the threaded rod 302 have opposite rotation directions. The two groups of movable rings 305 are respectively threadedly connected to the two ends of the outer surface of the threaded rod 302. A servo motor 304 is installed on the outside of one group of connecting blocks 301. One end of the threaded rod 302 is fixedly connected to the output end of the servo motor 304. Two groups of clamping pieces 307 are provided. The inner sides of the two groups of clamping pieces 307 are hinged to the two ends of one side of the telescopic arm 306, and the two ends of the other side of the telescopic arm 306 are respectively rotatably connected to the inside of the two groups of movable rings 305.

[0046] It can be understood by persons skilled in the art that the threaded rod 302 is driven to rotate by the output end of the servo motor 304, so that the two sets of movable circles 305 are moved closer to or farther away from each other. When they are closer, the telescopic arm 306 is in an extended state, so that the two sets of clamps 307 are moved away from each other, thereby clamping and fixing the inner wall of the alloy tube 102; and when they are moving away, the telescopic arm 306 is in a retracted state, so that the two sets of clamps 307 are moved closer to each other, thereby releasing the fixation on the inner wall of the alloy tube 102. Example 4

[0047] Please refer to Fig.14 As shown, the external polishing mechanism 6 includes a support plate 601 and a shell 605, support plates 601 are welded to the front and rear sides of the top of the base 1, the two groups of support plates 601 are internally rotatably connected with a third screw rod 602, the shell 605 is threadedly connected to the third screw rod 602, a guide rod 603 is welded between the two groups of support plates 601, the shell 605 is slidably connected to the guide rod 603, one end of the third screw rod 602 is fixedly connected to the output end of the second stepper motor 604, and the second stepper motor 604 is fixedly installed on the outside of one of the groups of support plates 601, and a slot for the alloy tube 102 to pass through is opened on the shell 605, and sealing rings 606 are installed on both sides of the slot.

[0048] Please refer to Fig.15 and Fig.16As shown, the inner bottom end of the shell 605 is inclined, and a mounting block 607 is welded to the inner top end of the shell 605. An electric telescopic rod 608 is fixedly mounted on the side of the mounting block 607 close to the sealing ring 606. The output end of the electric telescopic rod 608 is fixedly connected to a mounting piece 609. A sixth drive motor 610 is mounted on the outer side of the mounting piece 609. The output end of the sixth drive motor 610 passes through the outer side wall of the mounting piece 609 and is fixedly connected to a sand tray 611. A blowing fan 612 is arranged at the inner bottom end of the shell 605. A discharge port is opened on the side of the shell 605 close to the waste collection box 103. A cover plate 614 is installed on the outer side of the discharge port. The top of the cover plate 614 is fixedly connected to the output end of the cylinder 613, and the cylinder 613 is fixedly mounted on the top of the shell 605.

[0049] It can be understood by those skilled in the art that the output end of the second stepper motor 604 drives the third screw rod 602 to rotate, so that the shell 605 moves, and the center of the notch provided on the shell 605 is located on the same straight line as the center of the alloy tube 102, so that the shell 605 can pass through the alloy tube 102 and be sleeved on the outer surface of the alloy tube 102, and the inner wall of the sealing ring 606 is in contact with the outer wall of the alloy tube 102, and the output end of the electric telescopic rod 608 is extended to drive the sand disc 611 to contact the outer wall of the alloy tube 102, and at the same time, the sixth drive motor 610 is started to rotate the sand disc 611; because the two ends of the alloy tube 102 are clamped by the clamping mechanisms 3 on both sides, one of the first sets is driven by the output end of the third drive motor 117. The cylinder 116 rotates, and then the alloy tube 102 also rotates. Further driven by the output end of the second stepper motor 604, the shell 605 slides back and forth along the outer surface of the guide rod 603 to polish the outer wall of the alloy tube 102. Since the polishing of the outer wall of the alloy tube 102 is carried out inside the shell 605, the waste chips generated during the polishing process fall on the inner bottom end inclined surface of the shell 605. By turning on the blowing fan 612, the waste chips are prevented from adhering to the inner wall of the shell 605. Finally, the cover plate 614 is driven upward by the output end of the cylinder 613 to open the discharge port, so that the waste chips fall into the waste collection box 103 for collection; and when polishing alloy tubes 102 with different outer diameters, the sealing ring 606 can be replaced according to actual needs. Example 5

[0050] Please refer to Fig.12As shown, the internal polishing mechanism 4 includes a rotating circle 401, the rotating circle 401 is rotatably connected inside the mounting seat 122, an internal gear 402 is fixedly installed inside the rotating circle 401, a plurality of first gears 403 are rotatably connected inside the mounting seat 122, a rack 404 is slidably connected inside the mounting seat 122, a limit bar 406 is fixedly connected to the outer side of the rack 404, a limit groove matching the limit bar 406 is opened on the outer wall of the mounting seat 122, and the first gear 403 is connected to the internal gear 403. The gear 402 and the rack 404 are both meshed, one end of the rack 404 extends to the outside of the mounting seat 122 and is installed with an arc-shaped sand plate 405, and a group of second gears 408 are also rotatably connected inside the mounting seat 122, an external gear 407 is fixedly installed on the outside of the rotating circle 401, and the external gear 407 is meshed with the second gear 408, and a transmission motor 409 is fixedly installed inside the mounting seat 122, and the middle part of the second gear 408 is fixedly connected to the output end of the transmission motor 409.

[0051] Please refer to Fig. 9 and Fig.12 As shown, a fourth driving motor 123 is fixedly mounted on the kit 121, and an output end of the fourth driving motor 123 is fixedly connected to a main gear 124, a gear 125 is connected to the back of the mounting seat 122, and the gear 125 is meshed with the main gear 124, and an electric push rod 130 is fixedly mounted inside the kit 121, and a blowing device 131 is fixedly mounted on the output end of the electric push rod 130, and a plurality of groups of air holes 132 are provided on the outer peripheral surface of the blowing device 131.

[0052] It can be understood by those skilled in the art that the second gear 408 is driven to rotate by the output end of the transmission motor 409, so that the outer gear 407, the rotating circle 401 and the inner gear 402 rotate as a whole, and then all the first gears 403 rotate synchronously, so that all the racks 404 move synchronously toward the center of the circle close to the mounting seat 122 or toward the center of the circle away from the mounting seat 122, so that the arc sand plate 405 can be well in contact with the inner wall of the alloy tube 102 with different inner diameters, thereby improving the applicability; and the main gear 124 is driven to rotate by the output end of the fourth drive motor 123, so that the gear 125 and the mounting seat 122 rotate as a whole, and then all the arc sand plates 405 rotate to polish the inner wall of the alloy tube 102. Example 6

[0053] Please refer to Fig.10 and Fig.11As shown, the telescopic mechanism 5 includes a first stepper motor 501 and a second screw rod 502. The first stepper motor 501 is fixedly mounted inside the first sleeve 116. A mounting strip 503 is welded on the inner wall of the first sleeve 116. The second screw rod 502 is rotatably connected to the middle of the mounting strip 503. The other end of the second screw rod 502 is fixedly connected to the output end of the first stepper motor 501. A moving block 506 is threadedly connected to the outer surface of the second screw rod 502. A first rotating member 504 and a second rotating member 505 are also rotatably connected inside the first sleeve 116. The fourth sleeve 12 0 is rotatably connected with a third rotating member 507 and a fourth rotating member 508 inside, the third rotating member 507 and the fourth rotating member 508 are hinged to two ends of one side of the telescopic member 509, and two ends of the other side of the telescopic member 509 are respectively hinged to the first rotating member 504 and the second rotating member 505, the telescopic member 509 is connected to the moving block 506, the second sleeve 118 and the third sleeve 119 are provided with a limiting slide groove 510, the telescopic member 509 is installed with a limiting slide rod 511 adapted to the limiting slide groove 510, and the limiting slide rod 511 is slidably connected to the limiting slide groove 510.

[0054] It can be understood by those skilled in the art that the output end of the first stepper motor 501 drives the second screw rod 502 to rotate, causing the movable block 506 to move, driving the telescopic member 509 to be in an extended or retracted state. When extended, the second sleeve 118, the third sleeve 119 and the fourth sleeve 120 are driven to extend synchronously, and when retracted, the second sleeve 118, the third sleeve 119 and the fourth sleeve 120 are all retracted into the first sleeve 116, so that the internal polishing mechanism 4 can reciprocate along the inside of the alloy tube 102 to achieve polishing.

[0055] Please refer to Figure 5 As shown, a first sealing plate 126 is fixedly installed on the outer surface of the first sleeve 116, a pin shaft 127 is rotatably connected inside the top end of the first sealing plate 126, a fifth driving motor 128 is fixedly installed on the top of the first sealing plate 126, one end of the pin shaft 127 is fixedly connected to the output end of the fifth driving motor 128, and a second sealing plate 129 is fixedly connected to the outer surface of the pin shaft 127.

[0056] Please refer to Figure 4As shown, a driven wheel 110 is fixedly connected to the bottom end of the outer surface of the rotating seat 107, a first driving motor 108 is installed on the top of the movable seat 106, the output end of the first driving motor 108 is fixedly connected to the driving wheel 109, the driving wheel 109 is connected to the driven wheel 110 through a belt 111, and one end of the rotating rod 112 extends to the outside of the connecting seat 113 and is fixedly connected to the driven sprocket 114, a driving sprocket is rotatably connected to the top of the rotating seat 107, the driving sprocket is connected to the driven sprocket 114 through a chain, the middle part of the outer side of the driving sprocket is fixedly connected to the output end of the second driving motor 115, and the second driving motor 115 is installed on the outer side of the rotating seat 107 through the motor seat.

[0057] The working principle and use process of this device are as follows: a number of alloy tubes 102 to be polished are transported by the conveyor 101. When the alloy tube 102 reaches the top of the support plate 105, the output end of the electric lifting rod 104 is extended, so that the support plate 105 moves upward, and the alloy tube 102 is lifted up. One set of output ends of the double-axis motor 204 drives the first screw rod 202 on one side to rotate, so that the first sleeve 116 on one side and the clamping mechanism 3 thereon are integrally extended into one end of the alloy tube 102, and the clamping mechanism 3 clamps and fixes the alloy tube 102. Secondly, the output end of the second stepper motor 604 drives the third screw rod 602 to rotate, so that the shell 605 passes through the alloy tube 102 and is sleeved on the outer surface of the alloy tube 102, and the inner wall of the sealing ring 606 contacts the outer wall of the alloy tube 102. Then, the other set of output ends of the double-axis motor 204 drives the first screw rod 202 on the other side to rotate. The first sleeve 116 on the other side and the clamping mechanism 3 thereon are integrally extended into the other end of the alloy tube 102, and the clamping mechanism 3 also clamps and fixes the alloy tube 102. It is worth noting that the two ends of the alloy tube 102 do not contact the inner side of the first sealing plate 126, because the shell 605 itself has a certain thickness. If it contacts, a certain dead angle area will be generated, and this area cannot be polished. Therefore, a distance should be left between the end face of the alloy tube 102 and the inner side face of the first sealing plate 126 for the shell 605 to move, so that the outer wall of the alloy tube 102 can be polished more comprehensively, and the waste chips generated during the polishing process fall on the inner bottom end inclined surface of the shell 605. By turning on the blowing fan 612, the waste chips are prevented from adhering to the inner wall of the shell 605. Finally, the cover plate 614 is driven upward by the output end of the cylinder 613 to open the discharge port, so that the waste chips fall into the waste collection box 103 for collection.

[0058] After the outer wall of the alloy tube 102 is polished, Figure 2To specifically explain the polishing of the inner wall of the alloy tube 102 from a perspective, first, the shell 605 moves to the middle of the alloy tube 102, and the clamping mechanism 3 on the left continues to clamp the alloy tube 102, and the clamping mechanism 3 on the right first releases the clamping, and driven by the right output end of the dual-axis motor 204, the first sealing plate 126 on the right abuts against the right end surface of the alloy tube 102, then the clamping mechanism 3 on the right clamps the alloy tube 102 again, and the clamping mechanism 3 on the left releases the clamping, and then driven by the left output end of the dual-axis motor 204, the clamping mechanism 3 on the left moves to the outside of the alloy tube 102, and the pin 127 is driven to rotate by the output end of the fifth drive motor 128 on the left, so that the second sealing plate on the left 129 rotates downward, and then driven by the left output end of the dual-axis motor 204, the second sealing plate 129 on the left side abuts against the left end face of the alloy tube 102, and then the internal polishing mechanism 4 on the right side is driven by the telescopic mechanism 5 to reciprocate along the inside of the alloy tube 102 to achieve polishing. Since the first sleeve 116 on the right side extends into the alloy tube 102, a dead angle area exists. Therefore, the corresponding operations are performed in accordance with the above steps, so that the first sealing plate 126 on the left side abuts against the left end face of the alloy tube 102, the clamping mechanism 3 on the left side clamps the alloy tube 102, and the second sealing plate 129 on the right side abuts against the right end face of the alloy tube 102, thereby achieving a more comprehensive polishing of the inner wall of the alloy tube 102.

[0059] It is worth noting that the polishing of the inner wall of the alloy tube 102 is carried out under the cover of the first sealing plate 126 and the second sealing plate 129, and the generated waste chips remain inside the alloy tube 102. By providing a blowing device 131, the waste chips are prevented from adhering to the inner wall of the alloy tube 102, and the polishing of the inner wall of the alloy tube 102 is divided into two parts. After each part is completed, the first drive motor 108 and the second drive motor 115 on the corresponding side can be used in conjunction to make the clamped alloy tube 102 first lifted up and then rotated to face the waste collection box 103, and then the alloy tube 102 is rotated downward, so that the waste chips inside the alloy tube 102 are poured into the waste collection box 103 for collection. When performing the above steps, the position of the second sealing plate 129 on the opposite side and the position of the shell 605 will not affect the rotation of the alloy tube 102.
