[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] 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 hanging 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 a plurality of hanging chains 5, one end of the air pipe 8 is connected to the air pump 7, 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 arranged 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 suction holes 10, and the outer side wall of the mounting base 6 is fixedly provided with matching push blocks 601 of the same number as the suction lines; a distribution cavity 901 is provided inside the suction cup 9 and is interconnected with the mounting base 6 and the suction holes 10, and the air pipe 8 is a threaded telescopic tube.

[0033] The upper limit rotation of the mounting base 6 is provided with a rotating table 11, which is driven by the main driving assembly and performs 22.5° forward and reverse rotation. The upper limit sliding of the rotating table 11 is provided with 8 groups of active strips 22 distributed in a ring array, and the multiple groups of active strips 22 are driven by the linkage assembly and perform radial synchronous movement. The end of each group of active strips 22 extends out of the rotating table 11 and is fixedly connected to an L-shaped moving frame 23. The upper limit rotation of the L-shaped moving frame 23 is provided with a baffle 33, which is pushed by the pushing assembly and performs 180° up and down flipping movement, and the pushing assembly is provided with driving force by the matching push block 601; a scraper strip 34 is fixedly provided on the upper end surface of the baffle 33 for blocking or avoiding the adsorption hole 10, and a pressing block 35 is fixedly provided on the inner side of the L-shaped moving frame 23 for auxiliary pressing of the grinding wheel.

[0034] Furthermore, the present invention cooperates with a rotating table 11, a plurality 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, thereby keeping the inside of the suction cup 9 clean and ensuring 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 and reducing the processing accuracy problem caused by positioning error.

[0035] like Figure 6 , Figure 8 as well as Fig. 9 As shown, the main driving assembly includes an inner gear ring 12, a driving gear 13 and a motor 14. The motor 14 is installed in the mounting base 6. The output end of the motor 14 is fixedly connected to the driving gear 13. The driving gear 13 is meshedly connected to the inner gear ring 12. The inner gear ring 12 is fixedly set on the inner wall of the rotating table 11.

[0036] Furthermore, by arranging the inner gear ring 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 satisfying 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 shield and protect the adsorption hole 10 to prevent the adsorption hole 10 from being damaged or contaminated, thereby reducing the frequency of repair and maintenance and reducing the repair cost caused by failures.

[0037] 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 matching push block 601, the arc block 24 is squeezed downward, and the scraper bar 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 matching push block 601, so that the arc block 24 quickly bounces upward under the elastic force of the reset spring 25, and the scraper bar 34 also avoids away from the adsorption hole 10, so that the adsorption hole 10 can act normally on the grinding wheel workpiece.

[0038] like Figure 8-Figure 10As shown, the rear side of the rotating circular table 11 is protrudingly provided with a matching carrier 15, and the linkage assembly includes a second motor 16, a spur gear 17, an incomplete outer gear ring 18, and a rotating ring 19. The rotating ring 19 is installed in the rotating circular table 11 for limited rotation. The outer periphery of the rotating ring 19 is fixedly provided with an incomplete outer gear ring 18. The spur gear 17 is installed in the matching carrier 15 for limited rotation and meshes with the incomplete outer gear ring 18. The output end of the second motor 16 is coaxially fixedly connected to the spur gear 17. The rotating ring 19 is provided with the same number of arc-shaped driving grooves 20 as the active strips 22, and a push column 21 is inserted in each set of arc-shaped driving grooves 20, and the push column 21 is fixedly connected to the active strips 22.

[0039] Furthermore, by providing a spur gear 17, an incomplete outer gear ring 18, a swivel 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 groups of active strips 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.

[0040] 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, 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 strip 22 to move radially, and the L-shaped moving frame 23 fixedly connected to the active strip 22 drives the scraper strip 34 to move radially.

[0041] like Figure 7 , Figure 10-12 As shown, the L-shaped moving frame 23 is provided with a rectangular slot for accommodating the stop bar 33, and the rotating end of the stop bar 33 is fixedly plugged with a central shaft 32, and the central shaft 32 is limitedly rotated and installed on the L-shaped moving frame 23 and meshed with a driven gear 31, and the driven gear 31 is connected to the pushing assembly. The pushing assembly includes an arc block 24, a return spring 25, a vertical push plate 26, a cylindrical pin 27, a door-shaped moving frame 29 and a pushing rack 30, and the door-shaped moving frame 29 is limitedly slidably installed in the L-shaped moving frame 23 and fixedly connected to the pushing rack 30, and the pushing rack 30 is meshed with the driven gear 31. The door-shaped moving frame 29 is provided with an oblique slot 28, and a cylindrical pin 27 is plugged 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 limited block, and a return spring 25 is fixedly provided at the lower end of the limited block. An end of the limit block away from the vertical push plate 26 is fixedly connected to an arc block 24 , and an upper end of the arc block 24 extends out of the L-shaped moving frame 23 and contacts the matching push block 601 .

[0042] 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 moving frame 29 and the pushing rack 30 in coordination with the push block 601, the scraper strip 34 can adaptively perform a 180° up and down flipping movement 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.

[0043] When the present invention is in use: the assembly frame 4 and the mounting base plate 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 gear ring 12, so that the inner gear ring 12 drives the rotating table 11 to rotate counterclockwise by 22.5°. The L-shaped moving frame 23 moves away from the matching push block 601, so that the arc block 24 quickly bounces upward under the elastic force of the reset spring 25, and the scraper strip 34 avoids away from the adsorption hole 10, so that the adsorption hole 10 can normally act 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, the No. 2 motor 16 is turned on to drive the spur gear 17 to rotate, and the spur gear 17 acts on the incomplete outer gear ring 18, so that the swivel 19 rotates forward and reverse, and the arc-shaped driving groove 20 on the swivel 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 a role in calibration and positioning, but also has an auxiliary locking effect on the workpiece, further enhancing the stability of workpiece transportation.

[0044] 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 gear ring 12, so that the rotating table 11 rotates 22.5° clockwise, and the L-shaped moving 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 groove 28, so that the door-shaped moving frame 29 is driven by the force to push the rack 30 to move toward the direction of the push column 21, and the rack 30 acts on the driven gear 31, so that the blocking bar 33 is forced to flip upward 180°, so that the scraper bar 34 blocks and protects the adsorption hole 10.

[0045] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
