Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing equipment, in particular to a clamping and feeding device for a sheet metal polishing device. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, punching, cutting, compounding, folding, welding, riveting, splicing, forming, etc. The products processed by the sheet metal process are called sheet metal parts. In order to improve the aesthetics of sheet metal parts and the comfort during use, sheet metal parts are usually polished. During the polishing process, the sheet metal parts first need to be placed on a fixing device for fixing, and then polished. The existing polishing methods include the following two: the first is to polish the sheet metal parts by hand-held polishing wheels by staff, but the disadvantage of this method is that the polishing efficiency is low and the polishing effect of the sheet metal parts is poor; the second is to polish the sheet metal parts by placing them on a plate. The sheet metal part is placed on a workbench, and then the workbench is driven to rise to the corresponding position of the polishing device through a driving member, and then the polishing device is driven to move horizontally through a transmission device to automatically complete the polishing work on the surface of the sheet metal part. However, the defect of this polishing device is that since the workbench is arranged below the polishing device, after completing the polishing work on one side of the sheet metal part, the sheet metal part needs to be turned over, and the workers are tired of moving the sheet metal parts in and out, and there is a risk of injury to the workers. In addition, since the sizes of sheet metal parts are diverse and there is no universal fixing device, during the polishing process of the sheet metal parts, the sheet metal parts may be relatively displaced from the polishing device, thereby affecting the polishing effect. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a clamping and feeding device for sheet metal polishing devices that reduces labor costs and ensures stable position during sheet metal polishing. The technical solution of the utility model: a clamping and feeding device for sheet metal polishing devices, including an equipment base, a polishing device connected to the equipment base, a feeding device connected to the equipment base, a workbench connected to the equipment base, a lifting device and a controller for driving the workbench to rise and fall, the polishing device including a first sliding base slidably connected to the equipment base, a second sliding base slidably connected to the first sliding base, a polishing wheel fixedly connected to the second sliding base, a first rotating motor for driving the polishing wheel to rotate, a first hydraulic cylinder for driving the first sliding base to move along the Y-axis direction, and a second hydraulic cylinder for driving the second sliding base to move along the X-axis direction, the polishing The optical wheel is located above the workbench, the lifting device includes a plurality of third sliding bases slidably connected to the equipment base and a third hydraulic cylinder for driving the third sliding base to move in a vertical direction, one end of the third sliding base is fixedly connected to the workbench, the feeding device includes a first fixed frame, a plurality of rollers movably connected to the first fixed frame, a plurality of rollers fixedly connected to the rollers and a second rotating motor for driving the rollers to rotate, when the workbench is in an initial state, the upper surface of the workbench and the top of the roller are in the same horizontal plane, and the controller is electrically connected to the first rotating motor, the second rotating motor, the first hydraulic cylinder, the second hydraulic cylinder and the third hydraulic cylinder respectively. By adopting the above technical scheme, first, the staff moves the sheet metal to be processed to the top of the roller and places the sheet metal on the roller, and then controls the second rotating motor through the controller to drive the roller shaft to rotate, thereby driving the roller to rotate, and then the sheet metal moves in the direction of the workbench. When the sheet metal moves to the workstation on the workbench, the third hydraulic cylinder is controlled by the controller to drive the third sliding base to move vertically upward. Since the third sliding base is fixedly connected to the workbench, the workbench will also move vertically upward until the sheet metal contacts the polishing wheel, and then the first rotating motor is controlled by the controller to rotate the polishing wheel, and the polishing wheel polishes the sheet metal. Then, the control cabinet controls the first hydraulic cylinder and the second hydraulic cylinder to respectively drive the first sliding base and the second sliding base to move, so that the polishing wheel moves in the Y-axis direction and the X-axis direction, thereby completing the polishing of the surface of the sheet metal. In this way, the staff does not need to lift the sheet metal onto the workbench, and there is no obstruction from the equipment base. The staff can move the sheet metal more labor-savingly and reduce the risk of injury to the staff.

[0004] The utility model is further configured as follows: it also includes a fixing device, the workbench is provided with a plurality of through holes evenly distributed on the workbench, the fixing device includes a vacuum suction cup fixedly connected to the through holes, a connecting pipe connected to the vacuum suction cup and a vacuum pump connected to the connecting pipe, and the controller is electrically connected to the vacuum pump.

[0005] By adopting the above technical solution, when the sheet metal part moves to the workstation of the workbench through the feeding device, the vacuum pump is controlled by the controller to provide suction to the vacuum suction cup, so that the position of the sheet metal part is fixed. Regardless of the size of the sheet metal part, only a few more vacuum suction cups need to be set at the center position of the workbench to ensure the stability of the position of the sheet metal part, which can further improve the polishing effect of the sheet metal part.

[0006] The utility model is further configured as follows: it also includes a push-back device, which includes a second fixed frame, a plurality of push rods slidably connected to the second fixed frame, and a fourth hydraulic cylinder for driving the push rods to move. The movement direction of the push rods is toward the direction of the first fixed frame. When the workbench is in an initial state, the upper surface of the workbench is in the same plane as the plane where the bottom of the push rods are located, and the controller is electrically connected to the fourth hydraulic cylinder.

[0007] With the above technical solution, after the polishing work is completed, the controller controls the fourth hydraulic cylinder to drive the push rod to move in the direction of the workbench. Since when the workbench is in the initial state, the upper surface of the workbench and the plane where the bottom of the push rod are located are in the same plane, the push rod will push the sheet metal part in the direction of the roller, and then the controller controls the second rotary motor to reverse, so that the sheet metal part moves away from the workbench. The staff only needs to wait near the first fixed frame, and then turn over or move the sheet metal part that has been discharged. This can further reduce the work intensity of the staff, save labor costs, and improve work efficiency. The utility model is further configured as follows: the surface of the roller is provided with a rubber sleeve, and the diameter of the inner wall of the rubber sleeve is adapted to the diameter of the roller.

[0008] By adopting the above technical solution, since a rubber sleeve is provided on the surface of the roller, the rubber material has good friction, which can prevent the roller from slipping during the feeding or discharging of the sheet metal parts. The sheet metal parts cannot be accurately moved to the workstation of the workbench, resulting in the inability to fully polish the sheet metal parts, affecting the polishing effect.

DETAILED DESCRIPTION

[0012] like Figure 1-2 As shown, a clamping and feeding device for a sheet metal polishing device comprises an equipment base 1, a polishing device 2 connected to the equipment base 1, a feeding device 3 connected to the equipment base 1, a workbench 4 connected to the equipment base 1, a lifting device 5 and a controller 6 for driving the workbench 4 to rise and fall, the polishing device 2 comprises a first sliding base 7 slidably connected to the equipment base 1, a second sliding base 8 slidably connected to the first sliding base 7, a polishing wheel 9 fixedly connected to the second sliding base 8, a first rotating motor 10 for driving the polishing wheel 9 to rotate, a first hydraulic cylinder 11 for driving the first sliding base 7 to move along the Y-axis direction, and a second hydraulic cylinder 12 for driving the second sliding base 8 to move along the X-axis direction, the polishing wheel 9 is located above the workbench 4, The lifting device 5 includes a plurality of third sliding bases 13 slidably connected to the equipment base 1 and a third hydraulic cylinder 14 for driving the third sliding base 13 to move in a vertical direction. One end of the third sliding base 13 is fixedly connected to the workbench 4. The feeding device 3 includes a first fixed frame 15, a plurality of rollers 16 movably connected to the first fixed frame 15, a plurality of rollers 17 fixedly connected to the rollers 16 and a second rotating motor 18 for driving the rollers 16 to rotate. When the workbench 4 is in an initial state, the upper surface of the workbench 4 is in the same horizontal plane as the top of the roller 17. The controller 6 is electrically connected to the first rotating motor 10, the second rotating motor 18, the first hydraulic cylinder 11, the second hydraulic cylinder 12 and the third hydraulic cylinder 14 respectively.

[0013] First, the staff moves the sheet metal to be processed to the top of the roller 17 and places the sheet metal on the roller 17, and then controls the second rotary motor 18 through the controller 6 to drive the roller 16 to rotate, thereby driving the roller 17 to rotate, and then the sheet metal moves in the direction of the workbench 4. When the sheet metal moves to the workstation on the workbench 4, the third hydraulic cylinder 14 is controlled by the controller 6 to drive the third sliding base 13 to move vertically upward. Since the third sliding base 13 is fixedly connected to the workbench 4, the workbench 4 will also move vertically upward until the sheet metal is aligned with the polishing plate. The polishing wheel 9 contacts the sheet metal part, and then the controller 6 controls the first rotating motor 10 to work, so that the polishing wheel 9 rotates, and the polishing wheel 9 polishes the sheet metal part. Then, the control cabinet controls the first hydraulic cylinder 11 and the second hydraulic cylinder 12 to respectively drive the first sliding base 7 and the second sliding base 8 to move, so that the polishing wheel 9 moves in the Y-axis direction and the X-axis direction, thereby completing the polishing work on the surface of the sheet metal part. In this way, the staff does not need to lift the sheet metal part onto the workbench 4, and there is no obstruction from the equipment base 1. It is more labor-saving for the staff to carry the sheet metal part, and the risk of injury to the staff is reduced.

[0014] It also includes a fixing device 19, and the workbench 4 is provided with a plurality of through holes 20 evenly distributed on the workbench 4. The fixing device 19 includes a vacuum suction cup 21 fixedly connected to the through hole 20, a connecting pipe 22 connected to the vacuum suction cup 21 and a vacuum pump 23 connected to the connecting pipe 22. The controller 6 is electrically connected to the vacuum pump 23.

[0015] When the sheet metal part moves to the workstation of the workbench 4 through the feeding device 3, the vacuum pump 23 is controlled by the controller 6 to provide suction to the vacuum suction cup 21, so that the position of the sheet metal part is fixed. Regardless of the size of the sheet metal part, it is only necessary to set a few more vacuum suction cups 21 at the center position of the workbench 4 to ensure the stability of the position of the sheet metal part, which can further improve the polishing effect of the sheet metal part.

[0016] It also includes a push-back device 24, which includes a second fixed frame 25, a plurality of push rods 26 slidably connected to the second fixed frame 25, and a fourth hydraulic cylinder 27 for driving the push rods 26 to move. The movement direction of the push rods 26 is toward the direction of the first fixed frame 15. When the workbench 4 is in the initial state, the upper surface of the workbench 4 is in the same plane as the plane where the bottom of the push rods 26 is located, and the controller 6 is electrically connected to the fourth hydraulic cylinder 27. After the polishing work is completed, the fourth hydraulic cylinder 27 is controlled by the controller 6 to drive the push rod 26 to move in the direction of the workbench 4. Because when the workbench 4 is in the initial state, the upper surface of the workbench 4 and the plane where the bottom of the push rod 26 are located are in the same plane. Therefore, the push rod 26 will push the sheet metal in the direction of the roller 17, and then control the second rotating motor 18 to reverse through the controller 6, so that the sheet metal moves away from the workbench 4. The staff only needs to wait near the first fixed frame 15, and then turn over or move away the sheet metal that has been discharged. This can further reduce the work intensity of the staff, save labor costs, and at the same time improve work efficiency.

[0017] A rubber sleeve 28 is disposed on the surface of the roller 17 , and the diameter of the inner wall of the rubber sleeve 28 is matched with the diameter of the roller 17 .

[0018] Since a rubber sleeve 28 is provided on the surface of the roller 17, the rubber material has good friction, which can prevent the roller 17 from slipping during the feeding or discharging of the sheet metal parts. The sheet metal parts cannot be accurately moved to the working position of the workbench 4, resulting in the inability to fully polish the sheet metal parts, affecting the polishing effect.
