DETAILED DESCRIPTION

[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] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a high-precision punching and grinding device based on metal plate processing.

[0033] Example 1

[0034] In a typical implementation of the present application, Figure 1As shown, a high-precision punching and grinding device based on metal plate processing includes a body 1, a grinding mechanism 2 arranged on the body 1, and a punching mechanism 3 arranged on the body 1. The grinding mechanism 2 includes a conveyor belt 21 and a grinding belt 25. The body 1 is provided with the conveyor belt 21, and the conveyor belt 21 passes through the body 1. The upper part of the conveyor belt 21 on the body 1 and the part adjacent to the body 1 are open ends, so that the metal plate conveyed on the conveyor belt 21 passes through the wall surface of the body 1. The body 1 is provided with a grinding belt 25, and the grinding belt 25 is located above the conveyor belt 21. The bottom end of the grinding belt 25 is adjacent to the conveyor belt 21. The grinding belt 25 is used to grind the metal plate on the conveyor belt 21.

[0035] The punching mechanism 3 includes a punching head 38 and a placement plate 310. The punching head 38 is arranged on the machine body 1. The punching head 38 is located above the conveyor belt 21. The punching head 38 is located in front of the conveying direction of the conveyor belt 21. The grinding belt 25 is located behind the conveying direction of the conveyor belt 21. The punching head 38 is used to punch the metal plate on the conveyor belt 21. The placement plate 310 is arranged in the machine body 1. The placement plate 310 and the punching head 38 are located at the same height. The placement plate 310 is used to place punching heads 38 of different specifications.

[0036] When the specification of the punching head 38 is changed, the punching head 38 in use is pressed against the placement tray 310, and the punching head 38 in use is unloaded onto the placement tray 310. After the placement tray 310 is deflected, the spare punching head 38 on the placement tray 310 is used.

[0037] When using the present invention:

[0038] The metal plate is sent to the conveyor belt 21, and the conveyor belt 21 drives the metal plate to move in the machine body 1. The metal plate first moves to the bottom of the punching head 38 and stops moving. The punching head 38 moves down and rotates. The metal plate is punched by the punching head 38, and then the punching head 38 is reset. The metal plate moves again on the conveyor belt 21, and the metal plate moves to the bottom of the grinding belt 25 and stops moving. The grinding belt 25 grinds the punching position of the metal plate, and then the conveyor belt 21 drives the metal plate to move out of the machine body 1. When the punching head 38 needs to change its specifications, the punching head 38 stops rotating and punches. The hole head 38 moves toward the placement plate 310. After the punching head 38 is pressed against the placement plate 310, the punching mechanism 3 removes the punching head 38 to leave the punching head 38 on the placement plate 310. Then the placement plate 310 is deflected, and the punching heads 38 of other specifications on the placement plate 310 are installed again by the punching mechanism 3, so that the punching mechanism 3 completes the replacement of the specifications of the punching head 38. Therefore, when the continuous metal plate processing production line is produced, the punching specifications can be changed during the production process, avoiding a lot of time waste caused by the production line shutdown, and improving the production efficiency of the punching and grinding device.

[0039] Example 2

[0040] like Figure 2-Figure 4 As shown, the difference from the above embodiment is that the grinding mechanism 2 also includes a conveying motor 22, the conveying motor 22 is fixedly installed on the body 1, the conveying motor 22 is connected to the conveyor belt 21, a load-bearing plate is arranged in the inner ring of the conveyor belt 21, the load-bearing plate is fixedly connected to the inner wall of the body 1, the load-bearing plate is adjacent to the bottom end of the top surface of the conveyor belt 21, and conveying roller frames 23 are arranged on both sides of the body 1, the conveying roller frames 23 are adjacent to the body 1, the conveying end of the conveying roller frame 23 is at the same height as the conveyor belt 21, the width of the conveying roller frame 23 is adapted to the width of the conveyor belt 21, and the conveying roller frame 23 is used to transfer metal plates.

[0041] When the metal plate is conveyed, the metal plate is first transferred on the conveying roller frame 23. After the metal plate is transferred into the machine body 1, the metal plate is placed on the conveyor belt 21, and the conveying motor 22 is started. The conveying motor 22 drives the conveyor belt 21 to rotate, so that the metal plate moves on the conveyor belt 21.

[0043] When performing the grinding process, the grinding motor 26 is started, the grinding motor 26 drives a pulley 27 to rotate, a pulley 27 drives a belt 28 to rotate, the belt 28 drives another pulley 27 to rotate, the other pulley 27 drives the shaft roller 24 to rotate, the shaft roller 24 drives the grinding belt 25 to rotate, so that the grinding belt 25 grinds the metal plate.

[0044] Furthermore, a plurality of limiting rollers 29 are fixedly installed in the machine body 1. The limiting rollers 29 are symmetrically distributed below the grinding belt 25 and the punching head 38. The limiting rollers 29 are located above the conveyor belt 21. The limiting rollers 29 are adjacent to the conveyor belt 21. The limiting rollers 29 are used to limit the metal plate on the conveyor belt 21.

[0045] Among them, when the metal plate is conveyed, the metal plate will enter between the conveyor belt 21 and the limiting roller 29. The limiting roller 29 limits the metal plate to prevent the metal plate from being offset due to external force during processing, thereby ensuring that the metal plate is accurately positioned at the processing position and improving the accuracy of the punching and grinding processing.

[0046] Example 3

[0047] like Figure 5-Figure 8As shown, the difference from the above embodiment is that the punching mechanism 3 also includes a slide rail 31, which is fixedly installed on the inner top of the body 1, and a sliding member 32 is slidably matched on the slide rail 31. A screw rod 33 is rotatably matched with the inner top of the body 1, and the screw rod 33 passes through the sliding member 32. The screw rod 33 is threadedly matched with the sliding member 32. The length of the slide rail 31 and the screw rod 33 is adapted to the width of the conveyor belt 21. A stepper motor 34 is fixedly installed on the inner top of the body 1, and the stepper motor 34 is power-connected with the screw 33.

[0048] Furthermore, a hydraulic rod 35 is fixedly installed at the bottom end of the sliding member 32, and the telescopic end of the hydraulic rod 35 faces downward. A punching motor 36 is fixedly installed on the extension rod of the hydraulic rod 35, and a clamp 37 is fixedly installed on the shaft of the punching motor 36, and a punching head 38 is clamped and fixed on the clamp 37.

[0049] When punching is performed, the stepper motor 34 is started, the stepper motor 34 drives the screw 33 to rotate, the screw 33 drives the sliding member 32 to move on the slide rail 31, the sliding member 32 drives the hydraulic rod 35 to move, the hydraulic rod 35 is started, the hydraulic rod 35 drives the punching motor 36 to move downward, the punching motor 36 is started to drive the clamp 37 to rotate and move downward, the clamp 37 drives the punching head 38 to move downward and rotate, so that the punching head 38 punches the metal plate.

[0050] Furthermore, a servo motor 39 is fixedly installed on the inner wall of the body 1, and the servo motor 39 is located on the moving track of the punching head 38. A placement plate 310 is fixedly installed on the axis of the servo motor 39, and a positioning clamp arm 311 is rotatably engaged on the placement plate 310. The positioning clamp arm 311 is used to fix the punching head 38 on the placement plate 310. A rotating arm cylinder 312 is fixedly installed on the placement plate 310, and the rotating arm cylinder 312 is dynamically connected to the positioning clamp arm 311.

[0051] Furthermore, a plurality of receiving openings are provided on the placement plate 310, and the receiving openings are circular and evenly distributed on the placement plate 310, and the receiving openings are adapted to the cross-sectional dimensions of the punching head 38, and the positioning clamp arms 311 are divided into two parts and symmetrically distributed on both sides of the receiving openings, and the positioning clamp arms 311 on both sides are meshed with each other through teeth to be dynamically connected, and the plurality of positioning clamp arms 311 are adapted to each receiving opening respectively.

[0052] Furthermore, a fixing frame 313 is fixedly installed on the inner wall of the body 1, and the fixing frame 313 is located at the same height as the placement plate 310, and the fixing frame 313 is adjacent to the placement plate 310. A ratchet 314 is rotatably fitted on the fixing frame 313, and the ratchet 314 is adjacent to the top surface of the placement plate 310. The length of the ratchet 314 extends to the top of the placement plate 310, and a torsion spring 315 is sleeved on the axis of the ratchet 314, one end of the torsion spring 315 is connected to the ratchet 314, and the other end of the torsion spring 315 is connected to the fixing frame 313. A plurality of limiting rods 316 are fixedly installed on the top surface of the placement plate 310, and the limiting rods 316 are evenly distributed in a circular shape. The limiting rods 316 are respectively located between each adjacent accommodating opening, and the position of the ratchet 314 covers the rotation trajectory of the limiting rod 316, and the rotation direction of the ratchet 314 is opposite to the rotation direction of the limiting rod 316.

[0053] Among them, when the specification of the punching head 38 is changed, the operation of the punching motor 36 is stopped, and the punching head 38 is driven to move into the receiving opening of the placement plate 310. After the punching head 38 reaches the receiving opening, the clamp 37 releases the clamping and fixation of the punching head 38. When the punching head 38 reaches the receiving opening, the thrust of the punching head 38 causes the placement plate 310 to drive the positioning rod 316 to press against the ratchet 314. Since the rotation direction of the ratchet 314 is opposite to that of the placement plate 310, the placement plate 310 will be pressed by the ratchet 314 and cannot be reversed, thereby ensuring the stability of the operation of the placement plate 310. Then the servo motor 39 is started, and the servo motor 39 drives the placement plate 310 to deflect and then stop running, so that the spare punching head 38 rotates to the bottom of the clamp 37, and the spare punching head 38 is clamped and fixed by the clamp 37 again, thereby completing the replacement of the specifications of the punching head 38.

[0054] Furthermore, an electrically controlled translation platform 317 is fixedly installed on the inner wall of the body 1, and the length of the electrically controlled translation platform 317 is greater than the width of the conveyor belt 21. A brush arm 318 is fixedly installed on the moving platform of the electrically controlled translation platform 317. The brush arm 318 is located above the conveyor belt 21, and the brush arm 318 is adjacent to the conveyor belt 21.

[0055] The electrically controlled translation platform 317 is started, and the electrically controlled translation platform 317 drives the brush arm 318 to move back and forth, so that the brush arm 318 cleans the surface of the metal plate after the punching process to avoid debris on the metal plate.

[0056] The overall working principle of the punching and grinding device:

[0057] The metal plate is sent to the conveyor belt 21, and the conveyor belt 21 drives the metal plate to move in the machine body 1. The metal plate first moves to the bottom of the punching head 38 and stops moving. The punching head 38 moves down and rotates. The metal plate is punched by the punching head 38, and then the punching head 38 is reset. The metal plate moves again on the conveyor belt 21, and the metal plate moves to the bottom of the grinding belt 25 and stops moving. The grinding belt 25 grinds the punching position of the metal plate, and then the conveyor belt 21 drives the metal plate to move out of the machine body 1. When the punching head 38 needs to be changed in specifications, the punching head 38 stops rotating, and the punching head 38 moves to the placement disk 310. After the punching head 38 hits the placement disk 310, the punching mechanism 3 removes the punching head 38 to leave the punching head 38 on the placement disk 310, and then the placement disk 310 deflects, and the punching heads 38 of other specifications on the placement disk 310 are installed by the punching mechanism 3 again;

[0058] When the metal plate is conveyed, the metal plate is first transferred on the conveying roller frame 23. After the metal plate is transferred into the machine body 1, the metal plate is placed on the conveyor belt 21, and the conveyor motor 22 is started. The conveyor motor 22 drives the conveyor belt 21 to rotate, so that the metal plate moves on the conveyor belt 21.

[0059] When performing the grinding process, the grinding motor 26 is started, the grinding motor 26 drives a pulley 27 to rotate, the pulley 27 drives the belt 28 to rotate, the belt 28 drives another pulley 27 to rotate, the other pulley 27 drives the shaft roller 24 to rotate, the shaft roller 24 drives the grinding belt 25 to rotate, so that the grinding belt 25 grinds the metal plate;

[0060] When the metal plate is conveyed, the metal plate will enter between the conveyor belt 21 and the limiting roller 29. The limiting roller 29 limits the metal plate to prevent the metal plate from being offset due to external force during processing, thereby ensuring that the metal plate is accurately positioned at the processing position and improving the accuracy of the punching and grinding process.

[0061] When punching, the stepper motor 34 is started, the stepper motor 34 drives the screw 33 to rotate, the screw 33 drives the slide 32 to move on the slide rail 31, the slide 32 drives the hydraulic rod 35 to move, the hydraulic rod 35 is started, the hydraulic rod 35 drives the punching motor 36 to move downward, the punching motor 36 is started to drive the clamp 37 to rotate and move downward, the clamp 37 drives the punching head 38 to move downward and rotate, so that the punching head 38 punches the metal plate;

[0062] When the specification of the punching head 38 is changed, the operation of the punching motor 36 is stopped, and the punching head 38 is driven to move into the receiving opening of the placement plate 310. After the punching head 38 is in contact with the receiving opening, the clamp 37 releases the clamping and fixing of the punching head 38. When the punching head 38 is in contact with the receiving opening, the thrust of the punching head 38 causes the placement plate 310 to drive the positioning rod 316 to contact the ratchet 314. Since the rotation directions of the ratchet 314 and the placement plate 310 are opposite, the placement plate 310 is pressed by the ratchet 314 and cannot be reversed, thereby ensuring the stability of the operation of the placement plate 310. Then the servo motor 39 is started, and the servo motor 39 drives the placement plate 310 to deflect and then stop running, so that the spare punching head 38 rotates to the bottom of the clamp 37, and the spare punching head 38 is clamped and fixed by the clamp 37 again, thereby completing the replacement of the specifications of the punching head 38.

[0063] In addition, the electrically controlled translation platform 317 is started, and the electrically controlled translation platform 317 drives the brush arm 318 to move back and forth, so that the brush arm 318 cleans the surface of the metal plate after the punching process to avoid debris on the metal plate.

[0064] 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.
