The center of the bottom plate 1 is provided with a horizontal detection component 6 for detecting the horizontal state of the bottom plate 1, a pressure sensor 7 is arranged in the horizontal detection component 6, and the pressure sensor 7 is coupled with the driving component 5. The whole horizontal state of laser cutting machine base is judged through detecting the horizontal state of bottom plate 1 to horizontal detection subassembly 6, when placing the laser cutting machine base on the ground that has the slope, be in unilateral inclination because of bottom plate 1 is not in the horizontal state, horizontal detection subassembly 6 detects and applys the pressure sensor 7 pressure that is in the low department, the drive assembly 5 of low side begins work, drive stabilizer blade 3 begins to move along the axis direction of mounting hole 4, until bottom plate 1 is in the horizontal state again, horizontal detection subassembly 6 no longer applys pressure sensor 7 pressure, drive assembly 5 stop work, accomplish the levelness self-regulating work of laser cutting machine base, need not workman's manual regulation, improve horizontal adjustment precision and adjustment efficiency.

As shown in fig. 3, the driving assembly 5 includes a motor 51, a first bevel gear 52, a second bevel gear 53, a bearing 54, and a fixed shaft 55.

When the signal of the pressure sensor 7 is transmitted to the motor 51, the motor 51 is electrified and started to drive the second bevel gear 53 to rotate, the second bevel gear 53 drives the first bevel gear 52 to rotate, and the first bevel gear 52 drives the fixed shaft 55 to start rotating around the center of the bearing 54. Because the weight of the laser cutting machine makes the support leg 3 pressed and unable to rotate, the fixed shaft 55 and the support leg 3 generate relative motion again, so the support leg 3 starts to move along the axis direction of the mounting hole 4, the lower support leg 3 jacks up the laser cutting machine base until the bottom plate 1 is in a horizontal state again, the pressure sensor 7 is not pressed any more, no signal is sent to the motor 51 any more, the output shaft of the motor 51 stops rotating, and the horizontal self-adjustment of the laser cutting machine base is completed.

As shown in fig. 1, 4, and 5, the level detecting unit 6 includes a platen 61, a platen 62, balls 63, and a rolling groove 64. The pressing plate 61 and the pressing plate 62 are fastened up and down and then fixed by bolts, the pressing plate 62 is welded at the center of the bottom plate 1, and the thickness of the pressing plate 61 and the pressing plate 62 after fastening is equal to the thickness of the bottom plate 1. Four rolling grooves 64 are annularly and uniformly distributed on the top surface of the bedplate 62, and the depth of the rolling grooves 64 gradually increases from the edge of the bedplate 62 to the center of the bedplate 62 to form an inclined angle of 1 degree.

The stabilizer blade 3 moves along the axis direction of mounting hole 4 while spacing ring 12 takes place relative position in spacing intracavity 10 in step and changes, and when spacing ring 12 contradicted spacing chamber 10's lateral wall, spacing ring 12 was stopped to continue the removal to avoid fixed axle 55 and stabilizer blade 3 to take place the separation, guarantee the security of laser cutting machine base self-interacting process.

As shown in fig. 3, the bottom end of the support leg 3 is provided with a universal seat 13 in a ball hinge manner, and the bottom of the universal seat 13 is sleeved with a rubber seat 14. The universal seat 13 is utilized to rotate around the spherical hinge of the supporting leg 3, so that the bottom surface of the rubber seat 14 is attached to the ground, the contact area between the rubber seat 14 and the bottom surface is increased, and the stability of the laser cutting machine is improved.

The working principle of the horizontal self-adjusting laser cutting machine base is as follows: when the base of the laser cutting machine is placed on the ground with a gradient, the base plate 1 is in an inclined state with one side being high and the other side being low, the balls 63 between the pressing plate 61 and the platen 62 roll towards one end of the lower part in the rolling groove 64 under the gravity, the balls 63 press the pressure sensor 7 of the rolling groove 64 far away from the central end part of the platen 62, and the pressure sensor 7 is pressed to send out a signal to start the motor 51. After the motor 51 is electrified and started, the output shaft drives the second bevel gear 53 to rotate, the second bevel gear 53 drives the first bevel gear 52 to rotate, and the first bevel gear 52 drives the fixed shaft 55 to start rotating around the center of the bearing 54. Since the bottom of the fixing shaft 55 is screw-coupled with the through hole 11 at the top of the leg 3, the leg 3 should be driven to rotate synchronously when the fixing shaft 55 rotates. But because the weight of the laser cutter and the cooperation of the guide blocks 9 of the side walls of the legs 3 and the guide grooves 8 prevent the legs 3 from rotating, the legs 3 start to move away from the bearings 54 in the axial direction of the mounting holes 4. At this time, the support legs 3 jack up the lower part of the base of the laser cutting machine due to the reverse supporting force of the ground until the bottom plate 1 is in a horizontal state again. At this time, the balls 63 return to the end of the rolling groove 64 near the center of the platen 62 due to the depth of the rolling groove 64, thereby reducing the possibility that the balls 63 may erroneously touch the pressure sensor 7 due to vibration in the working state of the laser cutting machine, and further ensuring the machining precision of the laser cutting machine. The output shaft of the motor 51 stops rotating while the pressure sensor 7 is no longer pressed, and the laser cutting machine base completes horizontal self-adjustment.

Of course, the above is only a typical example of the utility model, and other embodiments of the utility model are also possible, and all technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of the utility model claimed.
