Description

Technical Field

[0001] The invention relates to the technical field of engraving machines, in particular to a numerical control engraving machine for a wooden table. Background Art

[0002] In terms of processing principle, engraving is a combination of drilling and milling. The engraving machine has multiple data input modes to meet your needs. Computer engraving machines are divided into two categories: laser engraving and mechanical engraving. Both types have high power and low power. Because the application range of engraving machines is very wide, it is necessary to understand the most suitable application range of various engraving machines.

[0003] When processing a wooden table top, it is necessary to place the wooden table top on the working surface of the engraving machine. In order to improve the engraving accuracy, it is necessary to locate the position of the wooden table top before engraving. In order to improve the smoothness of engraving, it is necessary to appropriately adjust the position of the table top, thereby improving the engraving efficiency. When engraving a wooden table top with traditional engraving, it is necessary to manually place the table top and correct the position of the table top. The correction accuracy is low, and the equipment itself is required to position the table top later, which increases the processing time. In addition, during the processing of the wooden table top, due to laser processing, a large amount of smoke will be generated. Therefore, an exhaust fan needs to be installed next to the engraving machine to exhaust the smoke in time. During the processing, the exhaust fan will be in operation all the time and needs to be manually turned on or off. That is, the structure in which the exhaust fan operates independently will increase the burden on the operator and increase the energy consumption of the equipment.

[0004] Based on this, a CNC engraving machine for wooden table tops is proposed. Summary of the invention

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.

[0031] See also Figure 1-Figure 6 , the present invention provides a technical solution:

[0032] A numerical control engraving machine for a wooden table, comprising a base 1, a sliding frame 4 is slidably connected to the upper end of the base 1, two sliding frames 4 are provided, a crossbeam 5 is connected to the upper end of the sliding frame 4, the crossbeam 5 structure is connected between the sliding frames 4, the crossbeam 5 structure can be driven to move by the movement of the sliding frame 4, a sliding seat 6 is slidably connected to the crossbeam 5, a laser 7 is connected to the sliding seat 6, the sliding seat 6 can move along the crossbeam 5, and the laser 7 itself can also slide on the sliding seat 6, when the laser 7 slides, its height will change, and the horizontal position of the laser 7 can be moved by the movement of the sliding frame 4 and the sliding seat 6;

[0033] The upper end of the base 1 is connected to the support block 2, and the upper end of the support block 2 is connected to the placement box 3. The support block 2 makes the placement box 3 in an overhead state. At this time, there is a certain gap between the upper end of the base 1 and the placement box 3. The outer side of the placement box 3 is connected to an exhaust pipe 11, and one end of the exhaust pipe 11 is connected to the placement box 3. Since the wooden table will be clamped and fixed at the upper left, the exhaust pipe 11 structure is also arranged at the upper left of the placement box 3. The exhaust pipe 11 is connected to the exhaust fan 19, and the operation state of the exhaust fan 19 is controlled by the controller 9. The placement box 3 is provided with a The double-bar groove 14 and the L groove 13, wherein the L groove 13 is in an "L" shape, and the double-bar groove 14 and the L groove 13 are kept in a horizontal state, and a connecting piece 27 is slidably connected to the double-bar groove 14, and two connecting pieces 27 are provided, and the two connecting pieces 27 correspond to the double-bar groove 14 one by one, wherein the double-bar groove 14 is composed of two parallel straight grooves, and the upper end of the connecting piece 27 is connected to the extrusion rod 20, and the connecting piece 27 is vertically connected to the lower end of the extrusion rod 20, and the extrusion block 21 is slidably connected to the extrusion rod 20, and the extrusion block 21 and the extrusion rod 20 are perpendicular to each other;

[0034] The base 1 is connected with a clamping mechanism which is used to first drive the squeezing rod 20 to limit the wooden table top, and then drive the squeezing block 1 21 to move to limit the wooden table top. The squeezing rod 20 is used to clamp one side of the wooden table top, and the squeezing block 1 21 and the squeezing block 2 22 are used to clamp the other side of the wooden table top. Both clamping positions interact with the placement box 3.

[0035] Specifically, Figure 2As shown, a limit strip 8 is connected to the sliding frame 4, a controller 9 is connected to one side of the limit strip 8, and a button 12 is connected to one side of the controller 9. The limit strip 8 structure serves to limit the structure of the extrusion block 22, wherein the button 12 structure is arranged on the side facing the through groove 10, when the button 12 is pressed once, the controller 9 can control the exhaust fan 19 to operate, and when the button 12 is pressed again, the exhaust fan 19 stops operating, wherein the processing size of the wooden table top is limited by the setting position of the button 12, that is, the wooden table top must satisfy the requirement that the button 12 can be pressed down before the wooden table top can be subsequently clamped and fixed.

[0036] Specifically, Figure 6 As shown, one end of the extrusion block 1 21 is slidably connected to the insertion rod 24, and the two ends of the insertion rod 24 are respectively connected to the extrusion block 22 and the extrusion spring 34. The structure of the insertion rod 24 makes the distance between the extrusion block 1 21 and the extrusion block 22 variable, thereby increasing the processable size range of the wooden table, so that the engraving machine can adapt to the engraving operations of wooden table sizes.

[0037] Specifically, Figure 2 and Figure 6 As shown, one end of the extrusion block 22 is rotatably connected to a roller 23, and a through groove 10 is provided on the placement box 3. By setting the roller 23 structure, structural wear is reduced, and at the same time, the movement of the extrusion block 22 structure is prevented from being blocked by the button 12, thereby improving the smoothness of the structural transmission.

[0038] Specifically, Figure 6 As shown, the clamping mechanism includes a slide post 17, and an L-groove 13 is provided on the base 1. When the slide post 17 moves, its structure will sequentially perform two mutually perpendicular linear movements. The slide post 17 is slidably connected to the L-groove 13, and a telescopic rod 15 is rotatably connected to the slide post 17, wherein the telescopic rod 15 is a single drive structure. The engraving machine can realize a single drive structure to clamp the wooden table, thereby improving the clamping stability. There is no mutual interference problem in the clamping drive, ensuring that a stable clamping operation can be performed. The telescopic rod 15 is rotatably connected to the base 1, and when the telescopic rod 15 is extended and retracted, its structure will also deflect accordingly.

[0039] A pull rod 26 is slidably connected to the base 1, and a symmetrical rod 28 is connected to one side of the pull rod 26. The symmetrical rod 28 is vertically connected to the outside of the pull rod 26, wherein the symmetrical rod 28 is in a horizontal state, and a connecting piece 27 is slidably connected to the symmetrical rod 28, wherein the lower end of the connecting piece 27 is slidably sleeved on the symmetrical rod 28, and a traction spring 31 is sleeved on the symmetrical rod 28, and the two ends of the traction spring 31 are respectively connected to the connecting piece 27 and the pull rod 26, and when no external force is applied, the traction spring 31 can pull the pull rod 26 and the extrusion rod 20 closer to each other;

[0040] A bottom slide groove 30 is provided at the lower end of the extrusion block 1 21 and the extrusion block 2 22. The bottom slide groove 30 relies on the insertion rod 24 for a smooth transition to prevent the upper end of the sliding column 17 from sliding on the bottom slide groove 30 and vibrating. The upper end of the sliding column 17 is slidably connected to the bottom slide groove 30. A slider 32 is connected to the sliding column 17. The slider 32 is slidably connected to the pull rod 26. The structure of the slider 32 enables the sliding column 17 to pull the pull rod 26 to move.

[0041] Specifically, Figure 6 As shown, the base 1 is connected with a deflection shaft 18, the telescopic rod 15 is rotatably connected to the deflection shaft 18, one end of the telescopic rod 15 is connected with a push tube 16, the push tube 16 is sleeved on the sliding column 17, and the deflection shaft 18 is vertically connected to one side of one end of the L-slot 13. The push tube 16 is provided to improve the stability of the structural transmission.

[0042] Specifically, Figure 5 and Figure 6 As shown, a slide rail 25 is connected to the base 1, and a clamping block 29 is slidably connected to the slide rail 25. The clamping block 29 is fixedly connected to one side of the pull rod 26. By setting the slide rail 25 and the clamping block 29 structure, the stability of the pull rod 26 structure sliding on the base 1 is improved.

[0043] Specifically, Figure 6 As shown, a limiting ring 33 is connected to the sliding column 17, and the upper end of the limiting ring 33 abuts against the lower end of the extrusion block 1 21 or the extrusion block 2 22. By setting the limiting ring 33, a certain support effect is played on the extrusion block 1 21 or the extrusion block 2 22, ensuring that the extrusion block 1 21 and the extrusion block 2 22 remain in a horizontal state.

[0044] To sum up, the CNC engraving machine for wooden table provided in this embodiment needs to fix the wooden table on the working table of the engraving machine when laser engraving of the wooden table is required, so that the engraved pattern is located in the center of the wooden table to improve the engraving accuracy. The operator needs to place the wooden table near the upper left corner of the placement box 3, and then start the telescopic rod 15, and use the extension of the telescopic rod 15 to push the sliding column 17 connected to one end of the telescopic rod 15 to move, wherein the sliding column 17 structure moves along the L-slot 13.

[0045] During the movement of the slide post 17, the slider 32 connected to the slide post 17 will be driven to move, wherein the slider 32 is slidably connected to the pull rod 26, wherein the trajectory of the slide post 17 at the beginning of its movement is perpendicular to the pull rod 26 structure. Therefore, during the movement of the slide post 17, the slider 32 can pull the pull rod 26 to move along the L-groove 13 structure. During this process, the slider 32 does not slide along the pull rod 26 structure, and the clamping block 29 moves along the slide rail 25 structure. The pull rod 26 is used to drive the extrusion rod 20 to move, and the extrusion rod 20 is used to drive the extrusion block 21 to move. At this time, the extrusion rod 20 moves toward the direction of the wooden table. As the slide post 17 moves, the extrusion rod 20 can push the wooden table toward the left inner wall of the placement box 3 until the placement box 3 and the extrusion rod 20 clamp and fix the wooden table at the same time.

[0046] The sliding column 17 continues to move, and the pull rod 26 structure still moves synchronously, but is limited by the wooden table and the placement box 3, so that the extrusion rod 20 structure stops moving, that is, it no longer moves with the pull rod 26 structure. At this time, the traction spring 31 structure is stretched, and the connecting piece 27 structure no longer slides along the double bar groove 14. At this time, the extrusion rod 20 completes the function of clamping one side of the wooden table.

[0047] When the telescopic rod 15 continues to extend, the slide column 17 enters the bending position of the L-groove 13, and the direction of the moving trajectory of the slide column 17 changes. At this time, the slider 32 structure begins to slide on the pull rod 26, and the pull rod 26 structure stops moving. Since the upper end of the slide column 17 is limited by the bottom slide groove 30 structure, the movement of the slide column 17 structure can drive the extrusion block 21 to move toward the wooden table, and the extrusion block 21 is used to abut and push the other side of the wooden table to move toward the placement box 3. When the other side of the wooden table also abuts against the inner wall of the placement box 3, the telescopic rod 15 cannot continue to extend. At this time, the wooden table can be stably fixed above the placement box 3, waiting for the subsequent laser engraving operation of the wooden table.

[0048] When the extrusion rod 20 moves, it can push the extrusion block 1 21 and the extrusion block 22 slidably connected thereon to move toward the limit strip 8. At this time, the roller 23 structure connected to one end of the extrusion block 22 can pass through the through groove 10 and abut against the limit strip 8. As the extrusion rod 20 continues to move, the extrusion spring 34 structure is compressed. After the extrusion block 22 stops moving, the extrusion block 1 21 will continue to move toward the extrusion block 22. At this time, the extrusion block 1 21 and the extrusion block 22 are close to each other, and when the extrusion block 1 21 pushes the wooden platform to move At this time, the roller 23 rolls on the limit strip 8. When the roller 23 rolls on the button 12, the controller 9 can control the exhaust fan 19 to operate. On the contrary, when the roller 23 structure is restored, the button 12 structure can be pressed again. At this time, the controller 9 controls the exhaust fan 19 to stop running, and cooperates with the clamping and fixing structure of the wooden table to realize automatic exhaust during engraving of the wooden table, and automatically stop exhaust after engraving is completed, thereby realizing automated wooden table processing operations, greatly improving the processing efficiency of the wooden table and improving its processing accuracy.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
