Description

Technical Field

[0001] This invention relates to the field of polishing apparatus technology, and more specifically, to a surface polishing apparatus for aluminum discs. Background Technology

[0002] Aluminum discs are circular metal materials made of aluminum alloy. In the production process of aluminum discs, in order to improve their surface quality and performance, their surface needs to be polished by a polishing device.

[0003] In the existing polishing equipment, because the aluminum discs are round, the polishing trajectory needs to be adjusted multiple times according to their shape to achieve a comprehensive polishing effect. This results in a long polishing process for a single aluminum disc, which in turn affects the overall processing efficiency. Furthermore, the grinding dust generated during the polishing process is difficult to collect effectively, and its accumulation in the polishing equipment can easily lead to excessive concentration and contamination of the aluminum disc workpiece surface.

[0004] Based on this, a surface polishing device for aluminum discs is proposed. Summary of the Invention

A fan is fixedly installed on the side of one support frame away from the outer surface of the work cabinet, and a vacuum cleaner is fixedly installed on the side of the other support frame away from the outer surface of the work cabinet. The exhaust port of the fan and the extraction port of the vacuum cleaner are both fixedly connected with a conduit. The other end of the conduit extends through the movable frame into the isolation sleeve. A support ring is fixedly installed on the upper surface of the work cabinet, and the upper surface of the support ring is in contact with the lower surface of the workbench.

[0010] As a further improvement of the present invention, the four sides of the outer surface of the fixed ring are provided with limiting blocks, the limiting blocks are inserted into the assembly base, and the assembly base, the fixed ring and the four sides of the upper surface of the polishing block are all provided with pick-up and put-out openings.

[0012] As a further improvement of the present invention, a docking plate is fixedly installed on both the upper and lower surfaces of the isolation sleeve. The upper surface of the upper docking plate is in contact with the lower surface of the movable frame. A sealing block matching the pick-up and put-out port is fixedly installed on the lower surface of the lower docking plate. A plurality of docking rods are evenly arranged on the outer surface of the isolation sleeve. A compression spring is movably installed on the outer surface of the docking rod.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein.

[0027] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0028] Please see Figures 1-5 As shown, a surface polishing device for aluminum discs includes a work cabinet 1. A motor 101 is fixedly installed inside the work cabinet 1. An inverted "L"-shaped support frame 102 is fixedly installed on the middle of both sides of the outer surface of the work cabinet 1. Limiting rods 103 are fixedly installed on both sides of the middle of the upper surface of the work cabinet 1. The other end of the limiting rod 103 is fixedly connected to the lower surface of the support frame 102 at the horizontal end. A fan 104 is fixedly installed on the side of one support frame 102 away from the outer surface of the work cabinet 1, and a vacuum cleaner 105 is fixedly installed on the side of the other support frame 102 away from the outer surface of the work cabinet 1. The exhaust port of the fan 104 and the extraction port of the vacuum cleaner 105 are both fixedly connected to a conduit 106. The other end of the conduit 106 extends through the movable frame 3 into the isolation sleeve 4. A support ring 107 is fixedly installed on the upper surface of the work cabinet 1.

[0029] It should be noted that the fan 104 can draw in external air and deliver the airflow into the duct 106. Since the other end of the duct 106 extends through the movable frame 3 into the isolation sleeve 4, the airflow delivered into the duct 106 can be simultaneously delivered into the isolation sleeve 4. When the polishing dust generated during the polishing process gathers in the isolation sleeve 4, the airflow input into the isolation sleeve 4 can blow away the dust to prevent it from adhering to the isolation sleeve 4. At the same time, the vacuum cleaner 105 is started to draw in the airflow into the isolation sleeve 4 through the duct 106 connected to it. At this time, the airflow can carry the dust and draw it into the vacuum cleaner 105 to achieve the collection and cleaning of polishing dust. The operating mechanism of the vacuum cleaner 105 is the same as that of a vacuum cleaner.

[0030] A workbench 2 is installed in the middle of the upper surface of the work cabinet 1. The upper surface of the support ring 107 is in contact with the lower surface of the workbench 2. The output end of the motor 101 is fixedly connected to the lower surface of the workbench 2. Several assembly seats 201 are evenly fixedly installed in a ring on the upper surface of the workbench 2. A fixing ring 202 is installed in the inner surface of the assembly seat 201. A limiting block 203 is fixedly installed on the four sides of the outer surface of the fixing ring 202. The limiting block 203 is inserted into the assembly seat 201. A polishing block 204 is fixedly installed on the inner surface of the fixing ring 202. The four sides of the upper surface of the assembly seat 201, the fixing ring 202, and the polishing block 204 are all provided with a pick-up and put-out port 205.

[0031] It should be noted that the worktable 2 is stably supported by the support ring 107, and the worktable 2 is rotated by the motor 101 with the connection point between the worktable 2 and the work cabinet 1 as the center point. When the worktable 2 rotates, it can drive several assembly seats 201 to rotate synchronously, so as to achieve the effect of adjusting the position of several assembly seats 201 and achieve the purpose of assembly line polishing. The angle required for the worktable 2 to rotate when adjusting the position of the assembly seat 201 can be calculated by the number of assembly seats 201 and the circularity of the worktable 2. Based on the angle data, the operation process of the motor 101 is set, that is, the single rotation angle of the worktable 2 controlled by the motor 101 is equal to the interval angle between several assembly seats 201, so as to ensure that the assembly seat 201 is accurately located directly below the polishing disk 305 and the suction cup 306 when adjusting the position.

[0032] By setting a fixing ring 202, the polishing block 204 is installed into the mounting base 201. When the diameter of the aluminum disc matches the diameter of the polishing block 204, the aluminum disc is placed in the concave polishing block 204. By rotating the aluminum disc, the lower surface and side surface of the aluminum disc can be polished with the help of the polishing block 204. With the pick-and-place opening 205 open, it is convenient to pick up and put away the aluminum disc placed in the polishing block 204.

[0033] A movable frame 3 is movably mounted above the workbench 2. Both sides of the movable frame 3 are movably sleeved on the outer surface of the limiting rod 103. Connecting sleeves 301 are fixedly installed on both sides of the middle part of the upper surface of the movable frame 3. An electric push rod 302 is fixedly installed on the middle part of the upper surface of the connecting sleeve 301. The other end of the electric push rod 302 is fixedly connected to the lower surface of the horizontal end of the support frame 102. A motor 303 is fixedly installed inside the connecting sleeve 301. Connecting rods 304 are movably and rotatably mounted on both sides of the middle part of the lower surface of the movable frame 3. The output end of the motor 303 is fixedly connected to the upper surface of the connecting rod 304.

[0034] A polishing disc 305 is fixedly installed on the lower surface of one of the connecting rods 304. The polishing disc 305 matches the polishing surface diameter of the polishing block 204. A suction cup 306 is fixedly installed on the lower surface of the other connecting rod 304. Several ventilation holes 307 are evenly opened on the upper surface of the suction cup 306. An isolation sleeve 4 is fixedly installed on the outside of both connecting rods 304.

[0035] It should be noted that the movable frame 3 is movably sleeved on the outer surface of the limiting rod 103, and the movable frame 3 and the support frame 102 are movably installed by means of the electric push rod 302. The movable frame 3 can be controlled to move up and down along the limiting rod 103 by the extension and retraction of the electric push rod 302. When the movable frame 3 is in the descending state, it will drive the polishing disc 305 and the suction cup 306 connected to the connecting rod 304 to descend synchronously. Since the polishing disc 305 and the polishing surface diameter of the polishing block 204 are matched, when the aluminum disc is placed on the polishing block 204, the descending polishing disc 305 will be embedded in the polishing block 204 and contact the upper surface of the aluminum disc. At this time, the motor 303 is started to control the polishing disc 305 to rotate by means of the connecting rod 304, so that the upper surface of the aluminum disc can be polished.

[0036] Next, the descending suction cup 306 will be simultaneously embedded into another set of polishing blocks 204 and come into contact with the upper surface of the aluminum disc placed on the polishing block 204. As the suction cup 306 continues to press down, it can perform vacuum adsorption on the upper surface of the aluminum disc. At this time, the motor 303 is started to control the rotation of the suction cup 306 through the connecting rod 304. The suction cup 306 can drive the adsorbed aluminum disc to rotate synchronously in the polishing block 204, thereby achieving polishing and grinding of the lower surface and sides of the aluminum disc with the help of the polishing block 204.

[0037] The upper and lower surfaces of the isolation sleeve 4 are both fixedly installed with docking plates 401. The upper surface of the upper docking plate 401 is in contact with the lower surface of the movable frame 3. The lower surface of the lower docking plate 401 is fixedly installed with a sealing block 402 that matches the pick-and-place port 205. The middle of the inner surface of the sealing block 402 is fixedly installed with a positioning block 405. The positioning block 405 is located on the outside of the suction cup 306. The length of the positioning block 405 is greater than the length of the pick-and-place port 205.

[0038] The outer surface of the isolation sleeve 4 is evenly provided with a plurality of docking rods 403. A compression spring 404 is movably installed on the outer surface of the docking rod 403. The lower surface of the docking rod 403 is fixedly connected to the upper surface of the docking plate 401 on the lower surface of the isolation sleeve 4. The upper surface of the docking rod 403 movably passes through the docking plate 401 on the upper surface of the isolation sleeve 4 and extends outward from the movable frame 3. The upper surface of the docking rod 403 is aligned with the upper surface of the movable frame 3. A limiting plate with a diameter larger than the diameter of the docking rod 403 is provided on the upper surface of the docking rod 403.

[0039] It should be noted that when the movable frame 3 is in the lowered state, the isolation sleeve 4, which is in contact with its lower surface, will first contact the assembly base 201. At this time, the sealing block 402 set on the lower surface of the docking plate 401 will be inserted into the take-up and put-down port 205 to seal the take-up and put-down port 205. Under this condition, the isolation sleeve 4 will wrap around the assembly base 201, thereby storing the polishing space in the isolation sleeve 4, thereby gathering the grinding dust generated during the polishing process to prevent it from scattering. The dust gathered in the isolation sleeve 4 can be cleaned and collected by the cooperation of the fan 104 and the vacuum cleaner 105.

[0040] After the isolation sleeve 4 makes contact with the mounting base 201, the movable frame 3 will continue to press down until the polishing disc 305 and the suction cup 306 are in contact with the aluminum disc placed on the upper surface of the polishing block 204. At this time, during the pressing process, since the isolation sleeve 4 has already made contact with the mounting base 201, the mounting base 201 can support the isolation sleeve 4, which will cause the isolation sleeve 4 to be unable to descend synchronously with the movable frame 3. In this case, as the movable frame 3 descends, the docking rod 403 set on the upper surface of the docking disc 401 on the lower surface of the isolation sleeve 4 will pass through the movable frame 3 and extend upward. Since the isolation sleeve 4 is a telescopic and foldable structure, it can ensure that when the isolation sleeve 4 is in the state supported by the mounting base 201, the movable frame 3 descends stably, driving the polishing disc 305 and the suction cup 306 to approach the aluminum disc. At the same time, when the docking rod 403 extends through the movable frame 3, the descent of the movable frame 3 will squeeze the compression spring 404.

[0041] Secondly, when the isolation sleeve 4 at the suction cup 306 position contacts the assembly base 201, and the sealing block 402 is embedded in the pick-and-place port 205, since the length of the positioning block 405 is greater than the length of the pick-and-place port 205, the positioning block 405 will move to the inner upper part of the polishing block 204. When an aluminum disc is placed on the upper surface of the polishing block 204, the positioning block 405 will apply upward pressure to the aluminum disc. When the suction cup 306 finishes polishing the aluminum disc and rises again, the suction cup 306 will drive the aluminum disc to rise synchronously. When the suction cup 306 is in the rising state, it indicates that the movable frame 3 will rise synchronously, thereby using the rise of the movable frame 3 to release the compression spring 404. When the compression spring 404 is compressed, it can elastically reset, thereby pushing the docking rod 403 to extend downward toward the movable frame 3, thereby indirectly controlling the unfolding of the isolation sleeve 4. The lower surface of the unfolded isolation sleeve 4 will exceed the lower surface of the suction cup 306. At this time, the positioning block 405 can press the aluminum disc as the suction cup 306 drives the aluminum disc to rise. As the suction cup 306 continues to rise, air can be introduced into the suction cup 306 through the vent hole 307, thereby releasing the vacuum adsorption state of the suction cup 306 and ensuring that the aluminum disc is separated from the suction cup 306. The detached aluminum disc will fall onto the mounting base 201, and as the mounting base 201 is repositioned, it can be removed to complete the polishing operation.

[0042] In use, the present invention first places an aluminum disc that matches the diameter of the polishing block 204. Then, the motor 101 is started to control the worktable 2 to rotate. During the rotation of the worktable 2, several assembly seats 201 can be rotated synchronously. During the repositioning and adjustment of the assembly seats 201, the aluminum discs are placed in sequence to achieve a continuous polishing effect. When the assembly seat 201 with the aluminum disc is placed rotates to the bottom of the polishing disc 305, the electric push rod 302 is started to control the movable frame 3 to descend along the limit rod 103. When the movable frame 3 is in the descending state, the isolation sleeve 4 that contacts its lower surface will contact the assembly seat 201 first. At this time, the sealing block 402 set on the lower surface of the docking disc 401 will be inserted into the pick-up and put-out port 205 to seal the pick-up and put-out port 205. Under these circumstances, the isolation sleeve 4 will wrap around the assembly seat 201, thereby storing the polishing space in the isolation sleeve 4.

[0043] After the isolation sleeve 4 and the mounting base 201 are assembled, the movable frame 3 can be controlled to continue to descend until the polishing disc 305 contacts the upper surface of the aluminum disc. At this time, the motor 303 is started to control the polishing disc 305 to rotate through the connecting rod 304, so that the upper surface of the aluminum disc can be polished. During the polishing process, the fan 104 and the vacuum cleaner 105 are started simultaneously. The fan 104 draws in the outside air and delivers the airflow into the duct 106. Since the other end of the duct 106 extends through the movable frame 3 into the isolation sleeve 4, the airflow delivered into the duct 106 can be simultaneously delivered into the isolation sleeve 4 to blow away the polishing dust. At the same time, the vacuum cleaner 105 draws in the airflow in the isolation sleeve 4 through the duct 106 connected to it. At this time, the airflow can carry the dust and draw it into the vacuum cleaner 105 to achieve the collection and cleaning of the polishing dust.

[0044] Secondly, when the polishing disc 305 completes the polishing operation on the upper surface of the aluminum disc, the electric push rod 302 can be used to control the movable frame 3 to rise along the limit rod 103. At this time, the rising movable frame 3 can drive the isolation sleeve 4 to separate from the assembly seat 201. In this case, the motor 101 can be started again to control the worktable 2 to rotate, thereby driving several assembly seats 201 to rotate synchronously. When the aluminum disc with the upper surface polished rotates with the assembly seat 201 to directly below the suction cup 306, the electric push rod 302 can be started to control the movable frame 3 to descend again, while driving the isolation sleeve 4 to reconnect with the assembly seat 201. After the isolation sleeve 4 and the assembly seat 201 are connected, the movable frame 3 is controlled to continue to press down until the suction cup 306 contacts the upper surface of the aluminum disc.

[0045] At this time, as the movable frame 3 descends, the docking rod 403 set on the upper surface of the docking plate 401 on the lower surface of the isolation sleeve 4 will extend upward through the movable frame 3. At the same time, when the docking rod 403 extends through the movable frame 3, the descent of the movable frame 3 will squeeze the compression spring 404. When the isolation sleeve 4 with the suction cup 306 at the position comes into contact with the assembly base 201, and the sealing block 402 is embedded in the pick-and-place port 205, the positioning block 405 will move to the inner upper part of the polishing block 204. When an aluminum disc is placed on the upper surface of the polishing block 204, the positioning block 405 will press the aluminum disc from above.

[0046] When the suction cup 306 contacts the upper surface of the aluminum disc, it can perform vacuum adsorption on the upper surface of the aluminum disc. At this time, the motor 303 is started and the connecting rod 304 controls the suction cup 306 to rotate, which will synchronously drive the aluminum disc to rotate in the polishing block 204. Thus, the polishing block 204 polishes the lower surface and sides of the aluminum disc. After the lower surface and sides of the aluminum disc are polished, the movable frame 3 can be controlled to drive the suction cup 306 to rise. At this time, the suction cup 306 will drive the aluminum disc to rise synchronously. When the suction cup 306 is in the rising state, it indicates that the movable frame 3 will rise synchronously. The rise of the movable frame 3 releases the compression spring 404, and the compression spring 404 can then elastically reset. This pushes the docking rod 403 to extend downwards towards the movable frame 3, thereby indirectly controlling the unfolding of the isolation sleeve 4. The lower surface of the unfolded isolation sleeve 4 will extend beyond the lower surface of the suction cup 306. At this time, the positioning block 405 can press the aluminum disc as the suction cup 306 lifts it up. As the suction cup 306 continues to rise, the pressed aluminum disc will stretch the suction cup 306. At this time, air can be introduced into the suction cup 306 through the vent hole 307, thereby releasing the vacuum adsorption state of the suction cup 306 and ensuring that the aluminum disc is separated from the suction cup 306. The detached aluminum disc will fall onto the assembly base 201, and as the assembly base 201 is repositioned, it can be removed to complete the polishing operation.

[0047] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
