In industrial production, large-scale machining centers are required for industrial processing in the process of precision machining of some workpieces.

[0003] The five-axis machining centers in existing devices often use Pro / E and Ansys to improve the rigidity and stability of large parts and the entire machine, and to suppress the deformation and vibration of the machine tool caused by the cutting force. However, when the vibration amplitude is large, the stability of the device is reduced. Utility Model Content

[0004] The utility model aims to solve the problem that the existing device has poor stability when the vibration amplitude is large. To this end, the utility model proposes a high-stability five-axis machining center, which can improve the stability of the device.

[0006] A stabilizing component is provided at the bottom of the fixing plate, and the stabilizing component includes a spring 1, and the spring 1 is fixedly connected to the fixing plate; a shock-absorbing rod is fixedly connected to the bottom of the fixing plate; an arc-shaped pipe is opened inside and penetrates the shock-absorbing base; a rubber block is fixedly connected to the inner wall of the arc-shaped pipe; the bottom of the shock-absorbing base is connected to a force-bearing rod by setting a spring 2; the bottom of the force-bearing rod is rotatably connected to a torsion spring rod; the bottom of the torsion spring rod is fixedly connected to a transmission rod; and the bottom of the transmission rod is rotatably connected to a rubber wheel.

[0007] Furthermore, two springs 1 are provided, and the two springs 1 are symmetrically distributed with respect to the force-bearing rod, so that the force of the spring 1 on the force-bearing rod is more uniform.

[0008] Furthermore, the stress-bearing rod is in a "cross" shape, and one end of the stress-bearing rod is located in the arc-shaped pipe, so that the shock-absorbing rod moves downward to squeeze the stress-bearing rod.

[0009] Furthermore, an auxiliary component is arranged on the side of the machining center body, and the auxiliary component includes an air pressure chamber, a piston at one end of the air pressure chamber is slidably connected to a push rod, and the other end of the air pressure chamber is fixedly connected to a rubber airbag.

[0010] Furthermore, the push rod is located at the bottom of the force-bearing rod, and the push rod and the force-bearing rod are in a fixed state, so that the force-bearing rod moves, which can squeeze the push rod to move.

[0011] Furthermore, the rubber airbag is located at a side position of the fixing plate, so that when the rubber airbag is expanded, it can be located at the fixing plate.

[0012] The difference from the prior art is that the beneficial effects of this application are:

[0013] (1) When the main body of the high-stability five-axis machining center generates vibration in the vertical direction, the fixed plate, spring 1, shock-absorbing rod, arc-shaped pipe and rubber block are used to reduce vibration; when the amplitude is too large, the shock-absorbing rod, force-bearing rod, spring 2, torsion spring rod and transmission rod are used to make the rubber wheel move and rotate on the ground to generate friction, thereby improving the stability of the device when the vibration amplitude is large.

[0014] (2) When the force-bearing rod moves downward, the push rod can be driven to move, and the pressure in the air pressure chamber is increased, driving the rubber airbag to expand, further reducing the shock of the fixed plate that is subsequently reset under the action of the spring, thereby further improving the stability of the device.

[0031] Embodiment 1

[0032] See also Figure 1-Figure 4 , as shown in the figure, a high-stability five-axis machining center includes a machining center body 100 and a shock-absorbing base 200, and a fixing plate 300 is fixedly installed at the bottom of the machining center body 100;

[0033] The bottom of the fixed plate 300 is provided with a stabilizing assembly 400, and the stabilizing assembly 400 includes a spring 1 410, and the spring 1 410 is fixedly connected to the fixed plate 300. Among them, a shock absorbing rod 420 is fixedly connected to the bottom of the fixed plate 300, and an arc-shaped pipe 430 is opened and penetrated inside the shock absorbing base 200, and a rubber block 440 is fixedly connected to the inner wall of the arc-shaped pipe 430. When the machining center body 100 vibrates in the vertical direction, the machining center body 100 drives the fixed plate 300 fixed thereto to vibrate, and the fixed plate 300 squeezes the spring 1 410 fixedly connected thereto, and moves, thereby driving the shock absorbing rod 420 fixedly connected thereto to move, so that the shock absorbing rod 420 enters the arc-shaped pipe 430, and is rubbed by the rubber block 440 to reduce shock. The bottom of the shock-absorbing base 200 is connected to a force-bearing rod 460 by setting a second spring 450. Two springs 1 410 are provided. The two springs 1 410 are symmetrically distributed about the force-bearing rod 460. The force-bearing rod 460 is in a "cross" shape, and one end of the force-bearing rod 460 is located in the arc-shaped pipe 430. When the amplitude is too large, the shock-absorbing rod 420 squeezes the force-bearing rod 460, and the force-bearing rod 460 pulls the second spring 450 fixedly connected thereto, resulting in movement. The bottom of the force-bearing rod 460 is rotatably connected to a torsion spring rod 470, and the bottom of the torsion spring rod 470 is fixedly connected to a transmission rod 480, and the bottom of the transmission rod 480 is rotatably connected to a rubber wheel 490. When the force-bearing rod 460 moves, it drives the torsion spring rod 470 rotatably connected thereto to move downward, and cooperates with the transmission rod 480 fixedly connected to the torsion spring rod 470 and the rubber wheel 490 rotatably connected to the transmission rod 480, so that the rubber wheel 490 moves and rotates on the ground, generating friction, thereby improving the stability of the device when the vibration amplitude is large.

[0034] During use, when the machining center body 100 vibrates in the vertical direction, the machining center body 100 drives the fixed plate 300 fixed thereto to vibrate, and the fixed plate 300 squeezes the spring 1 410 fixedly connected thereto to move, thereby driving the shock-absorbing rod 420 fixedly connected thereto to move, so that the shock-absorbing rod 420 enters the arc-shaped pipe 430 and is rubbed by the rubber block 440 to reduce shock; when the amplitude is too large, the shock-absorbing rod 420 squeezes the force-bearing rod 460, and the force-bearing rod 460 pulls the spring 2 450 fixedly connected thereto to move, so that the force-bearing rod 460 drives the torsion spring rod 470 rotatably connected thereto to move downward, and cooperates with the transmission rod 480 fixedly connected to the torsion spring rod 470 and the rubber wheel 490 rotatably connected to the transmission rod 480, so that the rubber wheel 490 moves on the ground and rotates on itself to generate friction.

[0035] To further improve the stability of the device, see Figure 1-Figure 5As shown in the figure, an auxiliary component 500 is arranged on the side of the machining center body 100, and the auxiliary component 500 includes a pneumatic chamber 510, and a push rod 520 is slidably connected to one end of the pneumatic chamber 510 by a piston. Among them, the push rod 520 is located at the bottom position of the force rod 460, and the push rod 520 and the force rod 460 are in a fixed state. When the force rod 460 is in a downward moving state, the push rod 520 fixedly connected to the force rod 460 can be driven to move. The other end of the pneumatic chamber 510 is fixedly connected to a rubber airbag 530, and the rubber airbag 530 is located at the side position of the fixed plate 300. When the push rod 520 is in a moving state, the pneumatic chamber 510 that is slidably connected to the piston of the push rod 520 increases the pressure in the pneumatic chamber 510, drives the rubber airbag 530 fixedly connected to the pneumatic chamber 510 to expand, and further damps the fixed plate 300 that is subsequently reset under the action of the spring 410, thereby further improving the stability of the device.

[0036] When in use, when the force-bearing rod 460 moves downward, it can drive the push rod 520 fixedly connected to the force-bearing rod 460 to move, and cooperate with the air pressure chamber 510 that is slidingly connected to the piston of the push rod 520, so that the pressure in the air pressure chamber 510 increases, driving the rubber airbag 530 fixedly connected to the air pressure chamber 510 to expand, and further damping the fixed plate 300 that is subsequently reset under the action of spring 1 410.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
