Description

Technical Field

[0001] The present invention specifically relates to the technical field of surface polishing, and specifically is a surface polishing device for stainless steel products. Background Art

[0002] The surface polishing device for stainless steel products is an important device for improving the appearance quality and surface roughness of stainless steel products; it can effectively remove the processing tool marks and burrs on the product surface and ensure the smoothness of the stainless steel product surface.

[0003] Currently, when traditional polishing devices polish stainless steel products, they can only polish one side of the product. When polishing cylindrical products, two different polishing devices are required, resulting in low work efficiency. Moreover, after traditional stainless steel products are polished, it is necessary to manually disassemble the polished workpieces from the fixtures, which is time-consuming and laborious, and cannot effectively ensure the continuity of the polishing device's work.

[0004] After retrieval, Chinese Patent Publication No. CN202011500793.5 discloses a polishing device and method for stainless steel products; it includes side plates, a horizontal position adjustment unit, a rotation unit, a polishing diameter adjustment unit, a polishing unit, and a fixing unit; a fixing unit is installed at the middle position on the side surface of the side plates, a rotation unit is installed on the rear side of the side plates through the horizontal position adjustment unit, a polishing diameter adjustment unit is installed on the side of the rotation unit close to the fixing unit, and a polishing unit is installed on the sliding block of the polishing diameter adjustment unit; the polishing unit includes a support one, a support shaft one, a rotating rod one, a support rod, a support shaft two, a support two, a fixing column, a movable sleeve, a pin shaft, a rotating rod two, a connecting shaft, a polishing rod, a sliding rod, a sliding sleeve, a sliding disc, a spring, an end cover, and a threaded sleeve.

[0005] When the above-mentioned patent structure polishes the product, the product is effectively clamped and fixed by two arc-top fixing plates. The polishing unit is driven to rotate by the rotation unit to achieve the internal polishing of the stainless steel product. By adjusting the distance between the two polishing rods in the polishing unit, effective polishing of products of different sizes can be achieved. Then, by adjusting the polishing rods to the outer surface of the stainless steel product and driving the polishing unit to rotate by the rotation unit, the surface polishing of the stainless steel product can be achieved. In this way, when polishing, it is necessary to polish one side first and then the other side, which will cause a long adjustment time. Moreover, when polishing the outside, the position clamped by the two arc-shaped fixing plates cannot be effectively polished, and the product needs to be clamped and fixed again, affecting the work efficiency. Summary of the Invention

[0006] The purpose of the present invention is to provide a surface polishing device for stainless steel products. In this device, an inclined frame is provided, and two guide grooves, a first rectangular groove and a second rectangular groove are opened on the inclined frame. Among them, two pressing plates are arranged inside the guide grooves. When the workpiece rolls along the guide grooves, the two pressing plates are pressed down. The bottoms of the two pressing plates are connected to the first L-shaped connecting plate through fixed rods and first connecting rods. The long ends of the pressing plates move downward, and the short ends move backward under the action of the rotating shaft, realizing the pulling of the first L-shaped connecting plate. The first L-shaped connecting plate is connected to the first flap through the first connecting rotating shaft. At this time, the end of the first flap far from the first connecting rotating shaft tilts upward, realizing that the first flap toggles the workpiece inside the first rectangular groove into the guide groove. The workpiece rolls along the guide groove into the second rectangular groove. After the workpiece contacts the rotating roller, through the rotation of the driving motor, the rotation of the workpiece is realized. At this time, the external polishing assembly is driven downward by the electric push cylinder, so that the second polishing wheel contacts the outer surface of the workpiece. At the same time, when the external polishing assembly moves downward, through the cooperation frame, the first polishing wheel in the internal polishing assembly enters the inside of the workpiece and contacts the inner wall of the workpiece, realizing the simultaneous polishing effect on the inner wall and the outer wall of the workpiece and improving the polishing efficiency; to solve the problems raised in the above background technology.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In the present invention, when in use, the inclined frame is fixedly mounted on the workbench through a support column. The lengths of the two support columns at the bottom of the inclined frame are different, effectively ensuring the inclination angle of the inclined frame. The workpiece is placed in a guide groove formed in the inclined frame through a mechanical gripper. Through the rotation of the workpiece itself, the workpiece rolls from high to low. During the rolling process of the workpiece, the workpiece presses down on the pressing plate, and the workpiece smoothly enters the first rectangular groove through the guide groove and is effectively supported by the support cross bars installed in the first rectangular groove; then the next workpiece is placed, and the workpiece presses down on the pressing plate in the same way. At this time, the short end of the pressing plate moves backward under the action of the rotating shaft and the torsion spring. When moving backward, the fixing rod at the bottom of the pressing plate pulls the first connecting rod, and the end of the first connecting rod away from the fixing rod is connected to an L-shaped connecting plate in a matching manner. The L-shaped connecting plate drives the first connecting rotating shaft to make one end of the first flap close to the pressing plate tilt upward, so as to make the first flap push the workpiece on the two support cross bars in the first rectangular groove into the guide groove, realizing the downstream flow of the workpiece and entering the second rectangular groove.

[0021] 2. In the present invention, after the workpiece enters the second rectangular groove, it contacts two rotating rollers. The two rotating rollers are connected by a connecting belt. One of the rotating rollers is connected to a driving motor in a cooperative manner to achieve synchronous rotation of the two rotating rollers, thereby effectively realizing the rotation of the workpiece. When the two rotating rollers drive the workpiece to rotate, the electric push cylinder at the top of the housing drives the mounting box to move downward. A hanging bracket is fixedly installed on the top of the mounting box. In this way, when the electric push cylinder drives the mounting box to move up and down, it effectively ensures the accurate position of the second polishing wheel inside the mounting box relative to the workpiece, preventing deviation and ensuring the polishing quality.

[0022] 3. In the present invention, when the mounting box moves downward, the cooperation frame fixedly installed on one side of the mounting box also moves downward simultaneously. The hypotenuse of the triangular support at the bottom of the cooperation frame contacts the roller. During the downward movement of the cooperation frame, it passes through the through groove opened on the Z-shaped frame, ensuring that the first polishing wheel is moved to the inner surface of the workpiece, achieving accurate positioning for the polishing treatment of the inner wall. When the triangular support presses the roller, the support plate on which the roller is installed drives the sliding plate to move forward along the slide rail under the action of the extrusion force. After the mounting box stops descending, the first polishing wheel just penetrates the inside of the workpiece. The first motor and the second motor drive the first polishing wheel and the second polishing wheel respectively to synchronously polish the inner and outer surfaces of the workpiece, improving the work efficiency significantly while ensuring the polishing quality.

[0023] 4. In the present invention, after the polishing is completed, the electric push cylinder drives the mounting box to move upward. At the same time, the cooperation frame drives the triangular support to separate from the roller. Under the action of the spring sleeved between the end of the sliding rod of the sliding plate and the second L-shaped plate, the sliding rod penetrates the second L-shaped plate, driving the first polishing wheel to move backward and separating the first polishing wheel from the workpiece. At this time, a workpiece is placed at the higher end of the inclined frame. During the rolling process of the workpiece, the workpiece presses down the pressing plate. When the first flap at the bottom of the first rectangular groove tilts upward, the end of the first connecting shaft far from the first connecting rod is connected to the second connecting shaft through the second connecting rod. When the first flap flips upward, the first connecting shaft simultaneously pulls the second connecting rod and the second L-shaped connecting plate. The second L-shaped connecting plate is cooperatively installed with the second flap through the second connecting shaft, synchronously causing the end of the second flap close to the first rectangular groove to tilt upward, pushing the processed workpiece into the guide groove. The automatic loading and unloading transmission of the workpiece is realized through the loading and unloading component, reducing the participation of personnel, and greatly improving the work efficiency while ensuring the polishing quality.

[0043] Two rollers 415 are fitted and installed inside the second rectangular groove 417; a connecting belt 416 is fitted and connected between the two rollers 415; one of the two rollers 415 penetrates through the side wall of the inclined frame 40 and is fixedly installed with the driving motor 410;

[0044] A second flap 411 is fitted and installed at the bottom of the second rectangular groove 417; the second flap 411 is arranged in the same structure as the first flap 45; a second connecting rotating shaft 412 at one end of the second flap 411 is fitted and installed with a second L-shaped connecting plate 414; both ends of the second connecting rotating shaft 412 are movably installed at the bottom of the inclined frame 40 through semi-circular plates; the second L-shaped connecting plate 414 is connected with one end of the first connecting rotating shaft 418 far away from the first L-shaped connecting plate 413 through a second connecting rod 49;

[0045] Two symmetrical through grooves 46 are opened on one side of the first rectangular groove 42 away from the second rectangular groove 417 inside the guide groove 41; a pressing plate 48 is movably installed inside the through groove 46 through a connecting shaft and a torsion spring; the pressing plate 48 is arranged in an L shape; the bottom of the pressing plate 48 is fitted and installed with a first connecting rod 47 through a fixing rod

[0046] By adopting the above technical solution, during use, the inclined frame 40 is fixedly installed on the workbench 3 through the support columns 43. The lengths of the two groups of support columns 43 at the bottom of the inclined frame 40 are different, effectively ensuring the inclination angle of the inclined frame 40. The workpiece 7 is placed in the guide groove 41 opened on the inclined frame 40 through a mechanical gripper. Through the rotation of the workpiece 7 itself, it realizes rolling from high to low. During the rolling process of the workpiece 7, the workpiece 7 presses down the pressing plate 48, and the workpiece 7 smoothly enters the first rectangular groove 42 through the guide groove 41 and is effectively supported by the support cross bars 44 installed inside the first rectangular groove 42;

[0047] Then place the next workpiece 7. The workpiece 7 presses down the pressing plate 48 by rolling. At this time, the short end of the pressing plate 48 moves backward under the action of the rotating shaft and the torsion spring. When moving backward, the fixing rod at the bottom of the pressing plate 48 pulls the first connecting rod 47. One end of the first connecting rod 47 away from the fixing rod is connected with the L-shaped connecting plate 413. The L-shaped connecting plate 413 drives the first connecting rotating shaft 418 to make one end of the first flap 45 close to the pressing plate 48 tilt upward, realizing that the first flap 45 pushes the workpiece 7 on the two support cross bars 44 in the first rectangular groove 42 into the guide groove 41, realizing that the workpiece 7 flows downstream and enters the second rectangular groove 417;

[0048] Please refer to Figures 3-8, 11, 15, 16; Further; One side of the inclined frame 40 is provided with an internal polishing component 5; The internal polishing component 5 includes a Z-shaped frame 50; The top of the Z-shaped frame 50 is symmetrically provided with slide rails 510; The slide rails 510 are fitted with a slide plate 59; One end of the slide plate 59 is fixedly installed with a roller 54 through a support plate 55;

[0049] One end of the slide plate 59 away from the support plate 55 is fixedly installed with a first L-shaped plate 52; A first motor 53 is fixedly installed on the first L-shaped plate 52; The output shaft of the first motor 53 penetrates through the first L-shaped plate 52 and is fitted with a first polishing wheel 51;

[0050] By adopting the above technical solution, after the workpiece 7 enters the second rectangular groove 417, it contacts the two rotating rollers 415. The two rotating rollers 415 are connected by a connecting belt 416. One of the rotating rollers 415 is cooperatively connected with the driving motor 410, so as to realize the synchronous rotation of the two rotating rollers 415, thereby effectively realizing the rotation of the workpiece 7;

[0051] When the two rotating rollers 415 drive the workpiece 7 to rotate, the electric push cylinder 3 at the top of the housing 2 drives the mounting box 100 to move downward. A suspension bracket 11 is fixedly installed on the top of the mounting box 100. In this way, when the electric push cylinder 3 drives the mounting box 100 to move up and down, it effectively ensures the accurate position of the second polishing wheel 103 inside the mounting box 100 and the workpiece 7, and no deviation will occur, ensuring the polishing quality;

[0052] Please refer to Figure 11 , 15 、16; In this embodiment; The end of the slide plate 59 away from the first L-shaped plate 52 is also fixedly installed with two symmetrically arranged slide rods 56; Both of the two slide rods 56 penetrate through two second L-shaped plates 511 fixedly installed on the Z-shaped frame 50; A spring 57 is sleeved between the end of the slide rod 56 away from the slide plate 59 and the second L-shaped plate 511; Sleeve tubes 58 are sleeved on the slide rods 56 between the second L-shaped plate 511 and the slide plate 59;

[0053] The top of the second rectangular groove 417 is cooperatively provided with an external polishing component 10; The external polishing component 10 includes a mounting box 100; A second polishing wheel 103 is installed inside the mounting box 100 through a rotating shaft; The rotating shaft on which the second polishing wheel 103 is installed is cooperatively connected with the output shaft of the second motor 101 through a belt 102; The top of the mounting box 100 is cooperatively installed with the top plate 21 of the housing 2 through a suspension bracket 11; The top of the mounting box 100 is also fixedly installed with the push rod of the electric push cylinder 3; The electric push cylinder 3 is fixedly installed on the top of the top plate 21;

[0054] By adopting the above technical solution, when the mounting box 100 moves downward, the mating frame 8 fixedly installed on one side of the mounting box 100 also moves downward. The hypotenuse of the triangular brace 80 at the bottom of the mating frame 8 contacts the roller 54. During the downward movement of the mating frame 8, it passes through the through slot 500 formed on the Z-shaped frame 50, ensuring that the first polishing wheel 51 is moved to the inner surface of the workpiece 7, and the polishing position of the inner wall is accurate;

[0055] Furthermore, when the triangular brace 80 presses the roller 54, the roller 54 is installed, and under the action of the extrusion force, the support plate 55 drives the slide plate 59 to move forward along the slide rail 510. After the mounting box 100 stops descending, the first polishing wheel 51 just penetrates into the interior of the workpiece 7. By driving the first polishing wheel 51 and the second polishing wheel 103 respectively with the first motor 53 and the second motor 101, the inner and outer surfaces of the workpiece 7 are polished synchronously. While ensuring the polishing quality, the working efficiency is also greatly improved;

[0056] Please refer to Figures 3-8 ; In this embodiment, a mating frame 8 is fixedly installed on one side of the mounting box 100, and the mating frame 8 is arranged in an L shape; a triangular brace 80 is integrally arranged on the inner side of the bottom of the mating frame 8; the hypotenuse of the triangular brace 80 cooperates with the roller 54;

[0057] Furthermore, the mounting box 100 is installed in cooperation with the negative pressure pipe 9 on the adjacent surface of the mating frame 8; one end of the negative pressure pipe 9 away from the mounting box 100 is installed in cooperation with the dust collection tank 6; the dust collection tank 6 is installed on the workbench 1 through a bracket;

[0058] Specifically, the bottom of the housing 2 is fixedly installed on the workbench 1, and U-shaped grooves for the inclined frame 40 to penetrate are formed on the side doors 22 at both ends of the housing 2;

[0059] By adopting the above technical solution, after polishing is completed, the electric push cylinder 3 drives the mounting box 100 to move upward. At the same time, the mating frame 8 drives the triangular brace 80 to separate from the roller 54. Under the action of the spring 57 sleeved between the end of the slide rod 56 of the slide plate 59 and the second L-shaped plate 511, the first polishing wheel 51 is driven to move backward, realizing the separation of the first polishing wheel 51 from the workpiece 7;

[0060] Furthermore, after the workpiece 7 is polished, the product to be processed is placed at the higher end of the inclined rack 40. During the rolling process of the workpiece 7, the workpiece 7 presses down the pressing plate 48. When the first flap 45 at the bottom of the first rectangular groove 42 tilts upward, the end of the first connecting rotating shaft 418 away from the first connecting rod 47 is connected to the second connecting rotating shaft 412 through the second connecting rod 49. When the first flap 45 flips upward, the first connecting rotating shaft 418 simultaneously pulls the second connecting rod 49 and the second L-shaped connecting plate 414. The second L-shaped connecting plate 414 is installed in cooperation with the second flap 411 through the second connecting rotating shaft 412. Synchronously, the end of the second flap 411 close to the first rectangular groove 42 tilts upward, pushing the processed workpiece 7 into the guide groove 41. The automatic loading and unloading transmission of the workpiece 7 is realized through the loading and unloading assembly 4, reducing the participation of personnel and greatly improving the work efficiency while ensuring the polishing quality.

[0061] The working principle of the present invention is as follows: When in use, the inclined rack 40 is fixedly installed on the workbench 3 through the support columns 43. The lengths of the two groups of support columns 43 at the bottom of the inclined rack 40 are different, effectively ensuring the inclination angle of the inclined rack 40. The workpiece 7 is placed in the guide groove 41 opened on the inclined rack 40 through the mechanical gripper. Through the rotation of the workpiece 7 itself, it rolls from high to low. During the rolling process of the workpiece 7, the workpiece 7 presses down the pressing plate 48, and the workpiece 7 smoothly enters the first rectangular groove 42 through the guide groove 41 and is effectively supported by the support cross bar 44 installed in the first rectangular groove 42.

[0062] Then, the next workpiece 7 is placed. The workpiece 7 presses down the pressing plate 48 by rolling. At this time, the short end of the pressing plate 48 moves backward under the action of the rotating shaft and the torsion spring. When moving backward, the fixed rod at the bottom of the pressing plate 48 pulls the first connecting rod 47. The end of the first connecting rod 47 away from the fixed rod is connected to the L-shaped connecting plate 413 in cooperation. The L-shaped connecting plate 413 drives the first connecting rotating shaft 418 to make the end of the first flap 45 close to the pressing plate 48 tilt upward, realizing that the first flap 45 pushes the workpiece 7 on the two support cross bars 44 in the first rectangular groove 42 into the guide groove 41, enabling the workpiece 7 to flow downstream and enter the second rectangular groove 417.

[0063] After the workpiece 7 enters the second rectangular groove 417, it contacts the two rollers 415. The two rollers 415 are connected by a connecting belt 416. One of the rollers 415 is connected to the driving motor 410 in cooperation, realizing the synchronous rotation of the two rollers 415, thereby effectively realizing the rotation of the workpiece 7.

[0064] When the two rotating rollers 415 drive the workpiece 7 to rotate, the electric push cylinder 3 at the top of the housing 2 drives the mounting box 100 to move downward. A hanging bracket 11 is fixedly installed at the top of the mounting box 100. In this way, when the electric push cylinder 3 drives the mounting box 100 to move up and down, it effectively ensures the accurate position of the second polishing wheel 103 inside the mounting box 100 relative to the workpiece 7, preventing deviation and ensuring the polishing quality.

[0065] When the mounting box 100 moves downward, the mating frame 8 fixedly installed on one side of the mounting box 100 also moves downward simultaneously. The hypotenuse of the triangular support 80 at the bottom of the mating frame 8 contacts the roller 54. During the downward movement of the mating frame 8, it passes through the through slot 500 formed on the Z-shaped frame 50, ensuring that the first polishing wheel 51 is moved to the inner surface of the workpiece 7, achieving accurate positioning for the inner wall polishing process.

[0066] When the triangular support 80 presses the roller 54, the roller 54 is installed, and the support plate 55 drives the sliding plate 59 to move forward along the slide rail 510 under the action of the extrusion force. After the mounting box 100 stops descending, the first polishing wheel 51 just penetrates into the interior of the workpiece 7. By driving the first polishing wheel 51 and the second polishing wheel 103 respectively through the first motor 53 and the second motor 101, synchronous polishing treatment of the inner and outer surfaces of the workpiece 7 is achieved. While ensuring the polishing quality, it also greatly improves the work efficiency.

[0067] After polishing is completed, the electric push cylinder 3 drives the mounting box 100 to move upward. At the same time, the mating frame 8 drives the triangular support 80 to separate from the roller 54. Under the action of the spring 57 sleeved between the end of the sliding rod 56 of the sliding plate 59 and the second L-shaped plate 511, the sliding rod 56 drives the first polishing wheel 51 to move backward, realizing the separation of the first polishing wheel 51 from the workpiece 7.

[0068] At this time, the workpiece 7 is placed at the higher end of the inclined frame 40. During the rolling process of the workpiece 7, the workpiece 7 presses the pressing plate 48. When the first flap 45 at the bottom of the first rectangular groove 42 tilts upward, the end of the first connecting rotating shaft 418 away from the first connecting rod 47 is connected to the second connecting rotating shaft 412 through the second connecting rod 49. When the first flap 45 flips upward, the first connecting rotating shaft 418 simultaneously pulls the second connecting rod 49 and the second L-shaped connecting plate 414. The second L-shaped connecting plate 414 is installed in cooperation with the second flap 411 through the second connecting rotating shaft 412. Synchronously, the end of the second flap 411 close to the first rectangular groove 42 tilts upward, pushing the processed workpiece 7 into the guide groove 41. Through the feeding assembly 4, automatic loading and unloading transmission of the workpiece 7 is realized, reducing human participation and greatly improving the work efficiency while ensuring the polishing quality.
