The development of numerical control cutting machines must meet the requirements of the development of modern mechanical processing industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting machines, etc. For the fastest efficiency, the highest cutting precision, and generally smaller cutting thickness, the plasma cutting machine also has a very fast cutting speed, and the cutting surface has a certain slope. When cutting H-shaped steel, a Z-axis lifting mechanism is usually used.

[0003] At present, in the same kind of technology, when the Z-axis lifts, since the sizes of the ram and the slide plate seat are about one time of the stroke, when the Z-axis stroke is relatively large, the mechanism is relatively bulky and has a relatively large inertia, resulting in the problem that a relatively large transverse motor is required to drive it. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A Z-axis lifting mechanism for an H-shaped steel cutting machine, including a large-stroke ram and fixing bolts. The outer surface of the large-stroke ram is fixedly installed with a Z-axis driving motor. The output end of the Z-axis driving motor is fixedly installed with a screw nut, and the outer surface of the screw nut is fixedly installed with a slide plate seat.

A connecting seat is arranged on the outer surface of the slide plate seat, a transverse driving motor is arranged on the outer surface of the connecting seat, a connecting piece is fixedly installed on the outer surface of the connecting seat, and a transverse ram is slidably connected to the outer surface of the connecting piece through the transverse driving motor.

[0006] Preferably, a first motor is fixedly installed at the bottom of the large-stroke ram. The output end of the first motor is fixedly installed with a second motor. The output end of the second motor is fixedly installed with a fixing seat. The outer surface of the fixing seat is fixedly installed with a mounting seat through the fixing bolt, and a laser universal swing head is fixedly installed on the outer surface of the mounting seat.

[0007] Preferably, a plurality of mounting holes are formed in the outer surface of the sliding plate seat, the plurality of mounting holes are arranged in an array, and fixing members are threadedly connected to the outer surfaces of the plurality of mounting holes.

When the long-stroke ram is relatively large, the size of the ram is about twice the stroke, but the size of the sliding plate seat is much smaller than the stroke, greatly reducing the weight of the z-axis. A relatively small transverse motor can be used to drive it. At the same time, the weight is reduced, so that the inertia of the mechanism during rapid movement is small, the dynamic performance is good, and the dynamic accuracy of the mechanism is also improved to a certain extent.

[0018] Embodiment 1:

[0019] Please refer to FIGS. 1-3 in combination.

[0020] A Z-axis lifting mechanism for an H-beam cutting machine includes a large-stroke ram 1 and a fixing bolt 14. A Z-axis driving motor 2 is fixedly installed on the outer surface of the large-stroke ram 1. The output end of the Z-axis driving motor 2 is fixedly installed with a screw nut 3, and the outer surface of the screw nut 3 is fixedly installed with a slide plate seat 5. A chute 4 is opened on the outer surface of the large-stroke ram 1, and the outer surface of the chute 4 is slidably connected to the slide plate seat 5. A connecting seat 7 is arranged on the outer surface of the slide plate seat 5. A transverse driving motor 8 is arranged on the outer surface of the connecting seat 7. A connecting member 9 is fixedly installed on the outer surface of the connecting seat 7. The outer surface of the connecting member 9 is slidably connected to a transverse ram through the transverse driving motor 8.

[0021] Specifically, by fixedly installing a Z-axis driving motor 2 on the outer surface of the large-stroke ram 1, and fixedly installing a screw nut 3 at the output end of the Z-axis driving motor 2, and fixedly installing a slide plate seat 5 on the outer surface of the screw nut 3. When the large-stroke ram 1 is relatively large, the size of the ram is about twice the stroke, but the size of the slide plate seat 5 is much smaller than the stroke, greatly reducing the weight of the z-axis. A relatively small transverse motor can be used to drive it. At the same time, the weight is reduced, so that the inertia of the mechanism during rapid movement is small, the dynamic performance is good, and the dynamic accuracy of the mechanism is also improved to a certain extent.

[0022] In the embodiment: A plurality of mounting holes 6 are opened on the outer surface of the slide plate seat 5. The plurality of mounting holes 6 are arranged in an array. Fixing members are threadedly connected to the outer surfaces of the plurality of mounting holes 6. The slide plate seat 5 is fixedly connected to the connecting seat 7 through the fixing members.

[0023] Specifically, a plurality of mounting holes 6 are opened on the outer surface of the slide plate seat 5. At the same time, the plurality of mounting holes 6 are arranged in an array, and fixing members are threadedly connected to the outer surfaces of the plurality of mounting holes 6. The slide plate connecting seat is fixedly connected to the connecting seat 7 through the fixing members, which is convenient for adjusting the height of the connecting seat 7 according to the installation requirements.

[0024] In the embodiment: The size of the slide plate seat 5 is smaller than that of the large-stroke ram 1, and the size of the transverse ram is larger than that of the large-stroke ram 1.

[0025] Specifically, since the size of the skateboard seat 5 is smaller than that of the large-stroke ram 1 and the cross-ram is larger than the large-stroke ram 1, the mechanism is relatively light and has a relatively small inertia, and can be driven by a relatively small transverse drive motor 8.

[0026] Working principle: Since the Z-axis drive motor 2 is fixedly installed on the outer surface of the large-stroke ram 1, the output end of the Z-axis drive motor 2 is fixedly installed with the outer surface of the lead screw nut 3, and the skateboard seat 5 is fixedly installed. At the same time, a chute 4 is opened on the outer surface of the large-stroke ram 1, and the outer surface of the chute 4 is slidably connected to the skateboard seat 5. In addition, a connecting seat 7 is arranged on the outer surface of the skateboard seat 5, and a transverse drive motor 8 is arranged on the outer surface of the connecting seat 7. A connecting member 9 is fixedly installed on the outer surface of the connecting seat 7, and the outer surface of the connecting member 9 is slidably connected to the cross-ram through the transverse drive motor 8. When the large-stroke ram 1 is relatively large, the size of the ram is about twice the stroke, but the size of the skateboard seat 5 is much smaller than the stroke, which greatly reduces the weight of the z-axis. A relatively small transverse motor can be used to drive it. At the same time, the weight is reduced. Compared with the related technology, a Z-axis lifting mechanism for an H-beam cutting machine provided by the present invention has the following beneficial effects: Thus, the inertia of the mechanism during rapid movement is small, the dynamic performance is good, and the dynamic accuracy of the mechanism is also improved to a certain extent.
