[0002] In the modern machining industry, grinding wheels are a crucial metalworking process, widely used in the cutting, grinding, and polishing of various metal materials.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention utilizes a rotating circular table, multiple sets of active bars arranged in a circular array, an L-shaped mobile frame, and scraping bars. This system shields the suction cup's suction holes when the equipment is idle, preventing the ingress of chips, dust, and other impurities, keeping the interior of the cup clean and ensuring proper function upon next use. Furthermore, a pressure block positioned at the end of the L-shaped mobile frame calibrates the grinding wheel, ensuring the workpiece remains correctly positioned during transport and minimizing machining accuracy issues caused by positioning errors.

[0018] 2. By arranging an internal gear ring, a driving gear, and a No. 1 motor in conjunction with the rotating table, the active strip and L-shaped movable frame can be driven to rotate axially while maintaining radial synchronization. This allows the scraper strip to automatically avoid the suction holes when the equipment is in use, ensuring the suction cup's inherent strength. When the equipment is idle, the scraper strip quickly shields the suction holes, preventing damage or contamination. This reduces the frequency of repairs and maintenance, and reduces repair costs associated with failures.

[0019] 3. By employing spur gears, an incomplete outer ring gear, a rotating ring, and a push column in conjunction with the arcuate drive slot, this invention converts the unidirectional driving force of the second motor into radial, synchronous motion of multiple sets of active bars, prompting the L-shaped moving frame to move closer to or further away from the grinding wheel workpiece. This achieves an auxiliary locking effect on the workpiece by the pressure block, reducing the risk of accidental slippage or falling of the workpiece during transport and improving operational safety.

[0020] 4. By arranging the driven gear, arc block, return spring, vertical push plate, cylindrical pin, door-shaped moving frame, and push rack in conjunction with the push block, the scraper strip can adaptively perform a 180° up and down flip movement as the position of the rotating table changes. The strong mechanical linkage not only meets the sealing effect of the adsorption hole, but also ensures that the pressure block can independently press and position the workpiece.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1 to 12 The present invention provides a technical solution: a vacuum adsorption and transfer device for grinding wheel processing, comprising a workbench 1, a column 2, a transverse support frame 3, an air pump 7, an air pipe 8, and a vacuum adsorption component arranged on the transverse support frame 3, one end of the transverse support frame 3 is rotatably matched with the column 2, and the other end of the transverse support frame 3 is fixedly connected to the assembly frame 4. The vacuum adsorption component includes an assembly frame 4, a lifting chain 5, a mounting base 6 and a suction cup 9; the upper end surface of the mounting base 6 is connected to the assembly frame 4 through multiple lifting chains 5, one end of the air pipe 8 is connected to the air pump 7, and the other end of the air pipe 8 passes through the transverse support frame 3 and the assembly frame 4 in turn and is connected to the mounting base 6. One end of the suction cup 9 is fixedly set at the lower end of the mounting base 6, and the other end of the suction cup 9 is provided with eight groups of suction lines distributed in a circular array, each group of suction lines is composed of a plurality of equally distributed adsorption holes 10, and the outer wall of the mounting base 6 is fixedly provided with the same number of mating push blocks 601 as the suction lines; a distribution cavity 901 is provided inside the suction cup 9, which is interconnected with the mounting base 6 and the adsorption holes 10, and the air pipe 8 is a threaded telescopic tube.

[0036] The mounting base 6 is provided with a rotating table 11 for upper limit rotation, which is driven by the main drive assembly and performs 22.5° forward and reverse rotation. The rotating table 11 is provided with 8 groups of active bars 22 distributed in a circular array for upper limit sliding. Multiple groups of active bars 22 are driven by the linkage assembly and perform radial synchronous motion. The end of each group of active bars 22 extends out of the rotating table 11 and is fixedly connected to an L-shaped movable frame 23. The L-shaped movable frame 23 is provided with a baffle 33 for upper limit rotation, which is pushed by the pushing assembly and performs 180° up and down flipping motion. The pushing assembly is provided with driving force by the cooperating push block 601; a scraper bar 34 is fixedly provided on the upper end face of the baffle 33 for blocking or avoiding the adsorption hole 10, and a pressure block 35 is fixedly provided on the inner side of the L-shaped movable frame 23 for auxiliary pressing of the grinding wheel.

[0037] Furthermore, the present invention cooperates with a rotating table 11, multiple groups of active strips 22 distributed in a circular array, an L-shaped movable frame 23 and a scraper strip 34. On the one hand, when the equipment is idle, the adsorption hole 10 of the suction cup 9 can be shielded and protected to prevent chips, dust and other impurities from entering, keep the inside of the suction cup 9 clean, and ensure that it can work normally when it is used next time; on the other hand, by arranging a pressure block 35 at the end of the L-shaped movable frame 23, the grinding wheel can be calibrated and positioned, thereby ensuring that the workpiece always maintains the correct position during the transportation process, reducing the processing accuracy problems caused by positioning errors.

[0038] like Figure 6 、 Figure 8 as well as Figure 9 As shown, the main drive assembly includes an inner ring gear 12, a driving gear 13 and a No. 1 motor 14. The No. 1 motor 14 is installed in the mounting base 6. The output end of the No. 1 motor 14 is fixedly connected to the driving gear 13. The driving gear 13 is meshed with the inner ring gear 12. The inner ring gear 12 is fixedly set on the inner wall of the rotating table 11.

[0039] Furthermore, by setting the inner ring gear 12, the driving gear 13 and the No. 1 motor 14 for use with the rotating table 11, it is possible to drive the active strip 22 and the L-shaped movable frame 23 to rotate axially while ensuring the radial synchronous movement, so that the scraper strip 34 can automatically avoid the adsorption hole 10 when the equipment is put into use, thereby ensuring the adsorption strength of the suction cup 9 itself; and when the equipment is idle, the scraper strip 34 can quickly block and protect the adsorption hole 10 to prevent the adsorption hole 10 from being damaged or contaminated, which can reduce the frequency of repair and maintenance and reduce the repair cost caused by failure.

[0040] Specifically, by turning on the No. 1 motor 14, it drives the driving gear 13 to rotate, and the driving gear 13 acts on the inner ring gear 12, so that the inner ring gear 12 drives the rotating table 11 to rotate forward and reverse. When the rotating table 11 rotates 22.5° clockwise, the L-shaped movable frame 23 is just located directly below the mating push block 601, the arc block 24 is squeezed downward, and the scraper 34 blocks and protects the adsorption hole 10; when the rotating table 11 rotates 22.5° counterclockwise, the L-shaped movable frame 23 moves away from the mating push block 601, so that the arc block 24 quickly bounces upward under the elastic force of the reset spring 25, and the scraper 34 also avoids away from the adsorption hole 10, so that the adsorption hole 10 can act normally on the grinding wheel workpiece.

[0041] like Figures 8-10As shown, a mating platform 15 is protruding from the rear side of the rotating circular platform 11. The linkage assembly includes a second motor 16, a spur gear 17, an incomplete outer ring gear 18, and a rotating ring 19. The rotating ring 19 is mounted within the rotating circular platform 11 for limited rotation. The incomplete outer ring gear 18 is fixedly mounted on the outer periphery of the rotating ring 19. The spur gear 17 is mounted within the mating platform 15 for limited rotation and meshes with the incomplete outer ring gear 18. The output end of the second motor 16 is coaxially fixedly connected to the spur gear 17. The rotating ring 19 is penetrated by an equal number of arcuate drive slots 20 as the active bars 22. A push column 21 is inserted into each set of arcuate drive slots 20, and the push column 21 is fixedly connected to the active bar 22.

[0042] Furthermore, by setting up a spur gear 17, an incomplete outer ring gear 18, a rotating ring 19 and a push column 21 for use in conjunction with the arc-shaped drive groove 20, the unidirectional driving force of the second motor 16 can be converted into radial synchronous movement of multiple sets of active bars 22, prompting the L-shaped moving frame 23 to approach or move away from the grinding wheel workpiece, thereby achieving an auxiliary locking effect of the pressure block 35 on the workpiece, which can reduce the risk of accidental sliding or falling of the workpiece during transportation and improve operational safety.

[0043] Specifically, by turning on the No. 2 motor 16, it drives the spur gear 17 to rotate, and the spur gear 17 acts on the incomplete outer ring gear 18, causing the rotating ring 19 to rotate forward and reverse. The arc-shaped driving groove 20 on the rotating ring 19 acts on the pushing column 21, so that the pushing column 21 is forced to drive the active bar 22 to move radially, and the L-shaped moving frame 23 fixedly connected to the active bar 22 drives the scraper bar 34 to move radially.

[0044] like Figure 7 、 Figure 10-12 As shown, the L-shaped movable frame 23 is provided with a rectangular slot for accommodating a stop bar 33. The rotating end of the stop bar 33 is fixedly connected to a central shaft 32. The central shaft 32 is mounted on the L-shaped movable frame 23 for limited rotation and is meshed with a driven gear 31. The driven gear 31 is connected to the push assembly. The push assembly includes an arc block 24, a return spring 25, a vertical push plate 26, a cylindrical pin 27, a door-shaped movable frame 29, and a push rack 30. The door-shaped movable frame 29 is mounted within the L-shaped movable frame 23 for limited sliding and is fixedly connected to the push rack 30. The push rack 30 is meshed with the driven gear 31. The door-shaped movable frame 29 is provided with an oblique slot 28, and a cylindrical pin 27 is inserted into the oblique slot 28. One end of the vertical push plate 26 is fixedly connected to the cylindrical pin 27, and the other end of the vertical push plate 26 is fixedly connected to a limit block. The lower end of the limit block is fixedly provided with a return spring 25. One end of the limiting block away from the vertical push plate 26 is fixedly connected to the arc block 24 , and the upper end of the arc block 24 extends out of the L-shaped moving frame 23 and contacts the matching push block 601 .

[0045] Furthermore, by arranging the driven gear 31, the arc block 24, the return spring 25, the vertical push plate 26, the cylindrical pin 27, the door-shaped movable frame 29 and the pushing rack 30 in coordination with the push block 601, the scraper 34 can adaptively perform a 180° flip movement up and down as the position of the rotating table 11 changes, and has strong mechanical linkage, which not only satisfies the sealing effect of the adsorption hole 10, but also ensures that the pressure block 35 can independently press and position the workpiece.

[0046] When the present invention is in use: the assembly frame 4 and the mounting base 6 are sent to the grinding wheel to be processed on the workbench 1 through the horizontal support frame 3, and then the No. 1 motor 14 is turned on to drive the driving gear 13 to rotate. The driving gear 13 acts on the inner ring gear 12, so that the inner ring gear 12 drives the rotating table 11 to rotate counterclockwise by 22.5 degrees. The L-shaped moving frame 23 moves away from the matching push block 601, so that the arc block 24 is quickly bounced upward under the elastic force of the return spring 25, and the scraper 34 is away from the adsorption hole 10 to avoid it, so that the adsorption hole 10 can act normally on the grinding wheel workpiece. In this process, when the vertical push plate 26 moves upward with the arc block 24, the cylindrical pin 27 thereon acts on the inclined slot 28, so that the door-shaped moving frame 29 is affected The force drives the pushing rack 30 to move in the direction away from the pushing column 21, and the pushing rack 30 acts on the driven gear 31, so that the blocking bar 33 is forced to flip downward 180° and get stuck in the rectangular slot, thereby exposing the pressure block 35. At this time, by turning on the No. 2 motor 16, it drives the spur gear 17 to rotate, and the spur gear 17 acts on the incomplete outer ring gear 18, so that the rotating ring 19 rotates forward and reverse. The arc-shaped driving groove 20 on the rotating ring 19 acts on the pushing column 21, so that the pushing column 21 is forced to drive the active bar 22 to move radially, and the pushing column 21 acts on the L-shaped moving frame 23, so that the pressure block 35 presses the center of the workpiece, which not only plays the role of calibration and positioning, but also has an auxiliary locking effect on the workpiece, further enhancing the stability of workpiece transportation.

[0047] When the equipment is idle, the No. 1 motor 14 is turned on again to drive the driving gear 13 to rotate. The driving gear 13 acts on the inner ring gear 12, causing the rotating table 11 to rotate 22.5° clockwise, and the L-shaped movable frame 23 also rotates until it is directly below the matching push block 601. At this time, the arc block 24 is squeezed downward, and the vertical push plate 26 moves downward with the arc block 24. The cylindrical pin 27 thereon acts on the inclined slot 28, so that the door-shaped movable frame 29 is driven by force to push the rack 30 toward the direction of the push column 21, and the push rack 30 acts on the driven gear 31, so that the block bar 33 is forced to flip upward 180°, so that the scraper bar 34 blocks and protects the adsorption hole 10.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
