Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, and in particular to a CNC cutting machine worktable. Background Technology

[0002] The CNC cutting machine's worktable is a crucial component, primarily responsible for supporting and carrying the material to be cut. The CNC cutting machine's worktable is typically used in conjunction with the CNC system and the cutting head to achieve automated, high-precision cutting operations.

[0003] During the cutting process, the residue generated during cutting can affect the stability of the material. If it is not cleaned in time, it may lead to a decline in cutting quality. Manually cleaning the cutting residue is not only time-consuming and labor-intensive, but also has a negative impact on the safety and work efficiency of the operators. An automatic slag removal system can effectively reduce manual intervention and reduce the labor intensity of the operators.

[0004] A search revealed Chinese patent CN119609283A, which discloses "A flame cutting machine for metal sheets with autonomous slag removal." This application discloses that "after the metal sheet is cut, the scraper is reset by the spring force inside the autonomous slag removal mechanism. Then, the scraper, in contact with the side of the horizontal placement frame, scrapes away the residue remaining on the surface of the horizontal placement frame, achieving autonomous slag removal. The autonomous slag removal of the flame cutting machine is achieved through the cooperation of the scraper, extension rod, and fixing rod, thereby effectively reducing the amount of metal residue on the surface of the horizontal placement frame." "Slag accumulation" Although the device works by pressing down on the spring when the plate is placed above the scraper and the horizontal placement frame, and removing the plate after cutting, the scraper moves up to scrape off the metal residue attached to the side of the horizontal placement frame due to the elasticity of the spring. However, the metal residue that falls from the plate after flame cutting is in a molten state and will stick firmly to the side of the horizontal placement frame. The elastic force generated by the spring is limited and cannot apply a strong enough force to remove the metal residue, so it cannot be guaranteed that the metal residue can be scraped off completely. Utility Model Content

[0005] This invention provides a CNC cutting machine worktable that solves the problem mentioned in the background art that it is impossible to apply sufficiently strong force to remove metal residues and thus cannot ensure that the metal residues can be scraped off cleanly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC cutting machine workbench, comprising a workbench frame, clamps, a pusher, and a scraper. Multiple clamps are arranged symmetrically on both sides of the upper surface of the workbench frame. Each clamp consists of two symmetrically arranged clamping plates, with a slot between the two plates. A strip is inserted into the slot. A scraper is fixedly connected to the inner side of each clamping plate. Scraper protrusions symmetrically arranged between two clamping plates in the same set of clamps abut against the two sides of the strip. A pusher is provided at one end of the workbench frame, and a push rod is fixedly connected to the output shaft of the pusher. Long screws are inserted through the vertical plates at both ends of the push rod. A through hole is provided on one side of each strip, and the long screw passes through the through hole of each strip.

[0007] Preferably, a grinding wheel column is provided on one side of the scraper, and the grinding wheel column is rotatably connected to the bottom plate of the clamping plate. A vertical groove is provided through the upper surface of the clamping plate, and the grinding wheel column is located in the vertical groove.

[0008] Preferably, the bottom surface of the vertical groove is provided with an insertion hole, and a rotating shaft is fixedly connected inside the grinding wheel column. The two ends of the rotating shaft protrude from the two ends of the grinding wheel column, and the central axis of the rotating shaft is collinear with the central axis of the grinding wheel column. The rotating shaft protruding from one end of the grinding wheel column is inserted into the insertion hole.

[0009] Preferably, a pressure plate is fixedly connected to the upper end of the clamping plate, and the rotating shaft protruding from the other end of the grinding wheel column passes through the hole opened in the pressure plate and a fixing nut is threaded onto the rotating shaft, with the fixing nut located above the pressure plate.

[0010] Preferably, the outer peripheral surfaces of two symmetrically arranged grinding wheel columns located in the same clamp abut against the two sides of the strip.

[0011] Preferably, both ends of the long screw are threaded with nuts, and the two nuts are located on the outer side of the push rod plate.

[0012] Preferably, a side plate is fixedly connected to one end of the workbench frame, and the pusher is fixed to the side plate. The pushing direction of the pusher is consistent with the length extension direction of the strip.

[0013] Preferably, the lower end of the pusher is provided with a bracket, and the bracket is fixed to the side plate.

[0014] Preferably, a slide rail is fixedly connected above one edge of the upper surface of the workbench frame, and a CNC cutting machine is slidably connected to the slide rail.

[0015] Preferably, a material collection hopper is provided below the strip, the material collection hopper is fixed on the workbench frame, and a receiving bin is slidably connected to the lower end of the material collection hopper.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When cleaning of the strips is required, multiple strips move synchronously via long screws, propelled by a pusher. The strips slide back and forth in slots within the clamps, where scrapers continuously remove cutting waste adhering to the strips, keeping the worktable clean. Meanwhile, the grinding wheel rotates to grind, remove burrs, or trim the surface. Finally, the residue falling from the strips falls into a collection bin via a hopper. The collection bin collects the residue, and by removing the collection bin from the hopper, the waste is discharged, ensuring the entire worktable remains clean and the cutting process proceeds smoothly.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] This utility model provides a CNC cutting machine worktable, such as Figure 1 and Figure 2 As shown, it includes a workbench frame 1, a clamp 3, a pusher 8 and a scraper 5. A slide rail 12 is fixedly connected above one edge of the upper surface of the workbench frame 1, and a CNC cutting machine 2 is slidably connected to the slide rail 12.

[0031] The slide rail 12 allows the CNC cutting machine 2 to slide smoothly on the worktable. The CNC cutting machine 2 uses existing equipment, with the reference model being "Huawei HNC-1500". The cutting head can move laterally along the rail on the CNC cutting machine 2. This allows the cutting head to move along two axes (X-axis and Y-axis) on the horizontal plane, ensuring that the cutting head moves along a specified path on the horizontal plane and providing precise cutting position.

[0032] When the CNC cutting machine 2 cuts the substrate, molten residue will fall onto the strip 7. After cooling, it will adhere to the side of the strip 7 and needs to be removed.

[0033] like Figure 3 As shown, multiple clamps 3 are arranged along both sides of the upper surface of the workbench frame 1, with the clamps 3 arranged symmetrically on both sides, as follows: Figure 4 As shown, the clamp 3 consists of two symmetrically arranged clamping plates with a slot 4 between them. A strip 7 is inserted into the slot 4, and a scraper 5 is fixedly connected to the inner side of the clamping plates. The convex edges of the scrapers 5, which are symmetrically arranged between the two clamping plates in the same clamping frame 3, abut against the two sides of the strip 7. The clamp 3 effectively fixes the strip 7 to the worktable through the arrangement of the clamping plates and scrapers 5. At the same time, when the strip 7 slides in the slot 4 of the clamp 3, the convex edges of the scrapers 5 on both sides directly contact the two sides of the strip 7, effectively removing cutting residue from the two sides of the strip 7 during the cutting process.

[0034] like Figure 1 and Figure 2 As shown, a side plate 11 is fixedly connected to one end of the workbench frame 1, and a pusher 8 is provided at one end of the workbench frame 1. The pusher 8 is fixed to the side plate 11, and a push rod 81 is fixedly connected to the output shaft of the pusher 8. Long screws 82 are inserted through the vertical plates at both ends of the push rod 81. A through hole 71 is provided through the side of one end of the strip 7, and the long screws 82 pass through the through holes 71 of multiple strips 7. Nuts are threaded to both ends of the long screws 82, and the two nuts are located on the outer side of the vertical plate of the push rod 81. The pushing direction of the pusher 8 is consistent with the extension direction of the strip 7, ensuring the linear movement of the strip 7. A bracket 111 is provided at the lower end of the pusher 8, and the bracket 111 is fixed to the side plate 11, supporting the pusher 8. The pusher 8 can be a hydraulic cylinder or an electric cylinder. The combination of the long screw 82 and the nut can simultaneously fix multiple strips 7. The two nuts are respectively clamped and fixed to the sides of the two end plates of the push rod 81, so that the long screw 82 can be fixed on the push rod 81. The pusher 8 pushes the long screw 82 to move through the push rod 81, thereby driving multiple strips 7 to move back and forth synchronously along the slot 4, ensuring the consistency of the movement of the strips 7.

[0035] When the output shaft of the pusher 8 extends to its limit position, the end of the strip 7 without the through hole 71 moves into the slot 4 of the opposite clamp 3 and does not disengage from the clamp 3. When the output shaft of the pusher 8 retracts to its limit position, the end of the strip 7 without the through hole 71 returns to the slot 4 of the clamp 3 on the same side as the side plate 11.

[0036] like Figure 7 and Figure 8 As shown, a grinding wheel post 6 is provided on one side of the scraper 5, and the grinding wheel post 6 is rotatably connected to the bottom plate of the clamping plate, as shown. Figure 5 and Figure 6 As shown, a vertical groove 31 is formed through the upper surface of the clamping plate, and the grinding wheel column 6 is located in the vertical groove 31. An insertion hole 32 is formed on the bottom surface of the vertical groove 31, as shown... Figure 9 As shown, a rotating shaft 61 is fixedly connected inside the grinding wheel column 6. Both ends of the rotating shaft 61 protrude from the ends of the grinding wheel column 6, and the central axis of the rotating shaft 61 is collinear with the central axis of the grinding wheel column 6. One end of the rotating shaft 61 protruding from the grinding wheel column 6 is inserted into the insertion hole 32. A pressure plate 62 is fixedly connected to the upper end of the clamping plate upright. The other end of the rotating shaft 61 protruding from the clamping plate 62 passes through a hole in the pressure plate 62, and a fixing nut is threaded onto the rotating shaft 61. The fixing nut is located above the pressure plate 62. The outer circumferential surfaces of two symmetrically arranged grinding wheel columns 6 located in the same clamping frame 3 abut against the two side surfaces of the strip plate 7. The grinding wheel column 6 can finely grind the surface of the strip plate 7, removing any remaining residue that the scraper 5 did not completely remove, ensuring that the surface of the strip plate 7 is smooth and flawless.

[0037] like Figure 1 and Figure 10 As shown, a hopper 9 is provided below the strip 7, and the hopper 9 is fixed on the workbench frame 1. A receiving bin 91 is slidably connected to the lower end of the hopper 9. The hopper 9 can effectively collect waste generated during the work process, avoiding pollution of the working environment by the waste. At the same time, the sliding connection design of the receiving bin 91 facilitates the centralized treatment of waste.

[0038] Using this utility model, such as Figure 1 and Figure 2 As shown, when cleaning of the strip 7 is required, multiple strips 7 move synchronously via long screws 82 under the push of the pusher 8. The strips 7 slide back and forth in the slots 4 of the clamp 3. The scraper 5 on the clamp 3 continuously cleans the cutting waste attached to the strips 7, keeping the worktable clean, while the grinding wheel 6 grinds, removes burrs, or trims the surface by rotating. Finally, the residue and waste falling from the strips 7 fall into the receiving bin 91 through the collecting hopper 9. The receiving bin 91 collects the residue and waste. Pulling the receiving bin 91 out of the collecting hopper 9 discharges the waste, ensuring the entire worktable remains clean and the cutting process proceeds smoothly.

[0039] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
