Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, and particularly relates to a sliding column vertical movement structure. Background Art

[0002] A laser cutting machine is a laser device that uses a laser to cut a sheet. The laser cutting machine mainly includes two longitudinally extending bed bodies, a workbench arranged between the two bed bodies, a cross beam carriage spanning and arranged on the two bed bodies, a y-axis driving mechanism for driving the cross beam carriage to move back and forth, an x-axis slide plate slidably arranged on the cross beam carriage along the x-axis, an x-axis driving mechanism for driving the x-axis slide plate to move left and right, a z-axis carriage slidably arranged on the x-axis slide plate, a laser cutting head arranged on the z-axis carriage, and a z-axis driving mechanism for driving the z-axis carriage to move up and down.

[0003] Since the laser cutting head configured in the existing laser cutting machine is an ordinary laser cutting head, that is, the processing axis of the laser cutting head always faces downward, a vertical plate structure is generally arranged on the z-axis carriage. However, with the need to improve processing flexibility and cutting accuracy to adapt to more complex and variable cutting requirements, a laser cutting head with a BC-axis rotation function needs to be configured. Therefore, the z-axis carriage not only needs to change its structure to accommodate the installation of the laser cutting head with the BC-axis rotation function, but also needs to consider the moving stability of the z-axis carriage to ensure processing accuracy. Summary of the Utility Model

[0004] In view of the deficiencies of the above-mentioned prior art, the purpose of the utility model is to provide a sliding column vertical movement structure, which uses a sliding column to cooperate with the installation of a laser cutting head with a BC-axis rotation function to ensure the smooth vertical movement of the sliding column.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sliding column vertical movement structure includes a vertical plate, a sliding column vertically extending in front of the vertical plate, a first guide rail vertically extending on the back surface of the sliding column, a first slider fixed on the vertical plate and slidably connected to the first guide rail, and a vertical movement driving mechanism for driving the sliding column to move vertically. The cross section of the sliding column is square. A side frame is arranged on the vertical plate beside the sliding column. A second guide rail vertically extending towards the side frame is arranged on one side surface of the sliding column. A second slider slidably connected to the second guide rail is fixed on the side frame. A precision installation flat plate is arranged at the bottom of the sliding column.

[0007] As a further improvement of the above technical solution, the side frame includes an L-shaped plate and a triangular inner plate arranged at the inner corner of the L-shaped plate. One plate surface of the L-shaped plate is fixed on the vertical plate, and the second slider is arranged on the other plate surface.

[0008] As a further improvement of the above technical solution, a plurality of horizontally extending waist-shaped holes are formed on the surface of the L-shaped plate facing the vertical plate, and the same number of threaded holes corresponding to the waist-shaped holes one by one are formed on the vertical plate. The fixing screws pass through the long holes and are connected to the threaded holes.

[0009] As a further improvement of the above technical solution, there are two first guide rails arranged side by side left and right, and one second guide rail is provided.

[0010] As a further improvement of the above technical solution, the inside of the sliding column is hollowed out to form a wire routing channel.

[0011] As a further improvement of the above technical solution, a weight-reducing hole is formed on the side surface of the sliding column.

[0012] As a further improvement of the above technical solution, the vertical movement driving mechanism includes a rack vertically arranged on the back surface of the sliding column, a vertical movement driving motor arranged on the vertical plate, and a gear arranged on the output end of the vertical movement driving motor. The gear meshes with the rack for transmission.

[0013] As a further improvement of the above technical solution, the precision machining installation flat plate and the sliding column are strengthened and connected through a triangular outer plate.

[0014] Beneficial effects of the present utility model: Compared with the prior art, the Z-axis carriage adopts a sliding column design. By arranging the first guide rail and the second guide rail, a dual guiding system is formed. When the vertical movement driving mechanism drives the sliding column to move vertically, the movement stability of the sliding column in the vertical direction can be significantly enhanced. The cooperation between the first guide rail and the first slider, and the combination of the second guide rail and the second slider act together on the sliding column to ensure that it moves more smoothly during vertical movement, reducing machining errors caused by shaking or vibration, thereby improving machining accuracy.

[0015] In addition, the sliding column with a square cross-section design provides better structural stability and torsional resistance compared with traditional circular or asymmetric shapes, ensuring the smoothness of the sliding column during vertical movement, further ensuring the accuracy of machining. The bottom of the sliding column provides sufficient connection support for the precision machining installation flat plate, enabling the laser cutting head with BC-axis rotation function to be stably installed on the precision machining installation flat plate.

Specific implementation manner

[0021] The present utility model provides a sliding column vertical movement structure. To make the purpose, technical solution and effect of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 3 , the present utility model provides a sliding column vertical movement structure, including a vertical plate 11, a sliding column 2 vertically extending in front of the vertical plate 11, a first guide rail 31 vertically extending on the back surface of the sliding column 2, a first slider 32 fixedly arranged on the vertical plate 11 and slidably connected with the first guide rail 31, and a vertical movement driving mechanism 6 for driving the sliding column 2 to move vertically. The cross-section of the sliding column 2 is square. A side frame 4 is arranged on the vertical plate 11 beside the sliding column 2. A second guide rail 33 vertically extending towards the side frame 4 is arranged on one side surface of the sliding column 2. A second slider 34 slidably connected with the second guide rail 33 is fixedly arranged on the side frame 4. A precision machining installation flat plate 51 is arranged at the bottom of the sliding column 2.

[0023] Compared with the prior art, the z-axis sliding frame adopts the design of the sliding column 2. By setting the first guide rail 31 and the second guide rail 33, a double guiding system is formed. When the vertical movement driving mechanism 6 drives the sliding column 2 to move vertically, the movement stability of the sliding column 2 in the vertical direction can be significantly enhanced. The cooperation between the first guide rail 31 and the first slider 32, and the combination of the second guide rail 33 and the second slider 34 act on the sliding column 2 together to ensure that it moves more smoothly during vertical movement, reduce the machining error caused by shaking or vibration, and thus improve the machining accuracy.

[0024] In addition, the slide post 2 is designed with a square cross-section, which provides better structural stability and torsional resistance compared to traditional circular or asymmetric shapes. This ensures the smoothness of the slide post 2 during vertical movement, further guaranteeing the machining accuracy. The bottom of the slide post 2 provides sufficient connection support for the precision machining mounting plate 51, enabling the laser cutting head 7 with BC-axis rotation function to be stably mounted on the precision machining mounting plate 51.

[0025] It should be understood that in a laser cutting machine, the vertical plate 11 and a flat plate 12 form a T-shaped slide plate, and the T-shaped slide plate is slidably arranged on the crossbeam support to achieve lateral movement.

[0026] Specifically, the side frame 4 includes an L-shaped plate 41 and a triangular inner plate 42 arranged at the inner corner of the L-shaped plate 41. One plate surface of the L-shaped plate 41 is fixed on the vertical plate 11, and the second slider 34 is provided on the other plate surface. The combination of the L-shaped plate 41 and the triangular inner plate 42 forms a stable support frame, significantly enhancing the overall strength and rigidity of the side frame 4, ensuring that even during high-speed and heavy-load cutting processes, the side frame 4 can remain stable and avoid deformation, thereby guaranteeing the machining accuracy.

[0027] Furthermore, a plurality of horizontally extending kidney-shaped holes 411 are formed on the plate surface of the L-shaped plate 41 facing the vertical plate 11, and threaded holes with the same number and one-to-one correspondence as the kidney-shaped holes 411 are formed on the vertical plate 11. The fixing screw 43 passes through the long hole and is connected to the threaded hole. The design of the kidney-shaped holes 411 allows the fixing screw 43 to finely adjust its position horizontally within a certain range, which means that the connection between the side frame 4 and the vertical plate 11 is no longer limited to a single fixed point, but has a certain degree of position adjustment ability, thus ensuring the smooth docking and cooperation of the second guide rail 33 and the second slider 34.

[0028] Two first guide rails 31 are provided and arranged side by side left and right, and one second guide rail 33 is provided. The two first guide rails 31 arranged side by side can provide a more stable and uniform guiding effect. Compared with a single guide rail, this design can significantly reduce the deflection and swing of the slide post 2 during vertical movement, thereby improving the guiding accuracy. This is crucial for a laser cutting machine because any slight deviation may directly affect the cutting quality and efficiency.

[0029] To optimize the circuit layout, the inside of the slide post 2 is hollowed out to form a wire routing channel 21. Setting the wire routing channel 21 inside the slide post 2 can effectively integrate and protect the power cables, optical fiber cables, and coolant pipes related to the laser cutting head 7. This built-in wire routing method avoids the problem of messy external wires, reduces the risk of wear and damage to external cables, and also facilitates the laying and maintenance of cables, improving the overall cleanliness and safety of the equipment.

[0030] Preferably, a weight-reducing hole 22 is formed on the side surface of the sliding column 2. The power cable, optical fiber line, and coolant pipe related to the laser cutting head 7 can enter the wiring channel 21 through the weight-reducing hole 22. The design of the weight-reducing hole 22 not only reduces the weight of the sliding column 2, but also optimizes its center of gravity distribution, which helps to improve the dynamic stability of the sliding column 2 during high-speed movement. The lighter and more stable sliding column 2 can reduce vibration and shaking, ensuring the accuracy and consistency of the laser cutting head 7 during the cutting process.

[0031] Specifically, the vertical movement driving mechanism 6 includes a rack 61 vertically arranged on the back surface of the sliding column 2, a vertical movement driving motor 63 arranged on the vertical plate 11, and a gear 62 arranged on the output end of the vertical movement driving motor 63. The gear 62 is in meshing transmission with the rack 61. Compared with other transmission methods, the direct meshing of the gear 62 and the rack 61 reduces the energy loss in the intermediate link and improves the efficiency of power transmission. This means that the power of the vertical movement driving motor 63 can be more effectively converted into the moving kinetic energy of the sliding column 2, reducing energy consumption.

[0032] Furthermore, the precision machining installation flat plate 51 and the sliding column 2 are strengthened and connected through a triangular outer plate 52. As a connecting part, the triangular outer plate 52 can significantly enhance the connection rigidity between the precision machining installation flat plate 51 and the sliding column 2 by using the stability principle of a triangle. This design can effectively reduce the structural deformation caused by external forces or vibrations during high-speed machining, ensuring the positioning accuracy of the laser cutting head 7 and improving the cutting quality and efficiency.
