Description

Technical Field

[0001] The utility model relates to the technical field of linkage mechanisms, in particular to a multi-axis linkage mechanism for a machining center. Background Art

[0002] The multi-axis linkage mechanism of a machining center is a device that allows the tool and workpiece to move simultaneously in multiple directions.

[0003] The high-precision machining of the multi-axis linkage mechanism of the machining center has high requirements on the environment. For example, vibration factors will affect the machining accuracy. When the multi-axis linkage mechanism of the machining center continues to vibrate, it will cause relative displacement between the tool and the workpiece, resulting in deviation in the machining size. In addition, the equipment is large in size and has high requirements on the stability and flatness of the site foundation, and cannot adapt to different sites.

[0004] Therefore, we provide a multi-axis linkage mechanism for a machining center. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-axis linkage mechanism for a machining center in order to solve the above-mentioned technical problems, so as to achieve the effects of reducing mechanism vibration and increasing applicability.

[0006] In view of this, the utility model provides a multi-axis linkage mechanism for a machining center, including a multi-axis linkage mechanism and a screw barrel inserted into the multi-axis linkage mechanism. There are at least four screw barrels, and the four screw barrels are distributed at the four corners of the lower surface of the multi-axis linkage mechanism. The screw barrel is threadedly connected to a rotating bolt, and the rotating bolt is rotatably connected to a rotating column away from one end of the screw barrel. A vibration-damping base is installed at the lower end of the rotating column, and a support base is installed on the lower surface of the vibration-damping base.

[0007] Preferably, a connecting plate is installed at the lower end of the rotating column, there are at least two connecting plates, and the two connecting plates are symmetrically distributed, and at least four supporting blocks are installed at the lower end of the connecting plate, and the four supporting blocks are distributed at four relative corners of the connecting plate.

[0008] Preferably, a support rod is installed on one adjacent side of the two support blocks, and the support rod is rotatably connected to at least two rotating rods.

[0009] Preferably, a sliding support block is provided between the two connecting plates, an air pressure block passes through the upper surface of the sliding support block, at least two sliding blocks are slidingly connected inside the sliding support block, and the two sliding blocks are symmetrically distributed, and rotating support columns are installed on opposite sides of the sliding block, and the rotating support columns are rotatably connected to the rotating rod.

[0010] Preferably, a piston block is installed at the lower end of the connecting plate, the piston block is slidably connected to the air pressure block, and the piston block fits tightly with the air pressure block. A spring is installed at one end of the sliding block, and the spring is arranged inside the sliding support block.

[0011] Preferably, at least four roller pillars are installed on the lower surface of the multi-axis linkage mechanism, and rollers are installed at the lower ends of the roller pillars.

[0012] Preferably, a rotating handle is installed at one end of the rotating bolt away from the screw barrel, and the rotating bolt extends out of the lower surface of the rotating handle.

[0013] Compared with the prior art, the present invention provides a multi-axis linkage mechanism for a machining center, which has the following beneficial effects:

[0014] 1. In the present invention, when the multi-axis linkage mechanism 1 vibrates during operation, the upper connecting plate 801 is acted upon by an external force to drive the piston block 805 to move toward the lower piston block 805. At the same time, the two piston blocks 805 squeeze each other in the sealed air pressure block 809 filled with high-pressure gas. At this time, the gas is compressed and resists the external force, effectively buffering the external pressure, reducing vibration, and ensuring the accuracy of the mechanism.

[0015] 2. In the present invention, before the multi-axis linkage mechanism 1 is operated, the rotating bolt 5 is adjusted up and down in the height direction based on the threaded connection between the screw barrel 2 and the rotating bolt 3. The rotating bolt 3 is adjusted to drive the support base 9 toward the ground until the support base 9 contacts the ground. When the ground is uneven, the rotating bolt 3 can be adjusted separately, so that the multi-axis linkage mechanism 1 is in a horizontal position, which improves the applicability of the mechanism and ensures the stability of the mechanism operation.

[0016] 3. In the present invention, when the connecting plate 801 moves downward due to an external force, the connecting rod 804 moves along with the connecting plate 801, and at the same time pushes the sliding block 807 to move toward the side of the spring 810. When the spring 810 is squeezed, it provides a buffering effect on the mechanism. When the external force disappears, the spring rebounds, and it is in a normal state.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A multi-axis linkage mechanism for a machining center, such as Figure 1 - Figure 4 As shown, it includes a multi-axis linkage mechanism 1 and a screw barrel 2 inserted into the multi-axis linkage mechanism 1. There are at least four screw barrels 2, and the four screw barrels 2 are distributed at the four corners of the lower surface of the multi-axis linkage mechanism 1. The screw barrel 2 is threadedly connected to a rotating bolt 3. The rotating bolt 3 is rotatably connected to a rotating column 7 at one end away from the screw barrel 2. A vibration-damping base 8 is installed at the lower end of the rotating column 7, and a support base 9 is installed on the lower surface of the vibration-damping base 8.

[0026] Before the multi-axis linkage mechanism 1 is operated, based on the threaded connection between the screw barrel 2 and the rotating bolt 3, the rotating bolt 5 is adjusted up and down in the height direction. The rotating bolt 3 is adjusted to drive the support base 9 to move toward the ground until the support base 9 contacts the ground. When the ground is uneven, the rotating bolt 3 can be adjusted separately to make the multi-axis linkage mechanism 1 in a horizontal position, thereby improving the applicability of the mechanism and ensuring the stability of the mechanism operation. When the multi-axis linkage mechanism 1 starts to operate, the vibration-damping base 8 below reduces the impact of vibration during the operation of the multi-axis linkage mechanism 1, effectively alleviates the vibration frequency of the mechanism, and ensures the accuracy of the mechanism during operation.

[0027] Example 2: A multi-axis linkage mechanism for a machining center, such as Figure 1 - Figure 4 As shown, a connecting plate 801 is installed at the lower end of the rotating column 7. There are at least two connecting plates 801, and the two connecting plates 801 are symmetrically distributed. At least four supporting blocks 802 are installed at the lower end of the connecting plate 801, and the four supporting blocks 802 are distributed at four relative corners of the connecting plate 801.

[0028] A support rod 803 is installed on one adjacent side of the two support blocks 802 , and the support rod 803 is rotatably connected to at least two rotating rods 804 .

[0029] A sliding support block 806 is arranged between the two connecting plates 801, and an air pressure block 809 passes through the upper surface of the sliding support block 806. At least two sliding blocks 807 are slidingly connected inside the sliding support block 806, and the two sliding blocks 807 are symmetrically distributed. Rotating support columns 808 are installed on opposite sides of the sliding block 807, and the rotating support columns 808 are rotatably connected to the rotating rod 804.

[0030] A piston block 805 is installed at the lower end of the connecting plate 801. The piston block 805 is slidably connected to the air pressure block 809, and the piston block 805 and the air pressure block 809 are tightly fitted. A spring 810 is installed at one end of the sliding block 807, and the spring 810 is arranged inside the sliding support block 806.

[0031] When the multi-axis linkage mechanism 1 vibrates during operation, the upper connecting plate 801 is acted upon by an external force to drive the piston block 805 to move toward the lower piston block 805. At the same time, the two piston blocks 805 squeeze each other in a closed air pressure block 809 filled with high-pressure gas. At this time, the gas is compressed and will resist the external force, effectively buffering the external pressure, reducing vibration, and ensuring the accuracy of the mechanism. When the external force disappears, the compressed gas expands and returns to its original state. When the connecting plate 801 is acted upon by an external force and moves downward, the connecting rod 804 moves with the connecting plate 801, and at the same time pushes the sliding block 807 to move toward the side of the spring 810. When the spring 810 is squeezed, it will provide a buffering effect on the mechanism. When the external force disappears, the spring rebounds, and it is in a normal state.

[0032] like Figure 1 - Figure 4 As shown, at least four roller pillars 6 are installed on the lower surface of the multi-axis linkage mechanism 1, and rollers 5 are installed at the lower ends of the roller pillars 6.

[0033] Before the mechanism is running, the multi-axis linkage mechanism 1 is pushed to a suitable position under the rolling support of the roller 5 to improve the flexibility of the mechanism. At this time, the support base 9 is adjusted. When the support base 9 contacts the ground, it provides a limiting effect for the roller 5 to ensure the stability of the mechanism during operation.

[0034] like Figure 1 - Figure 4 As shown, a rotating handle 4 is installed at one end of the rotating bolt 3 away from the screw barrel 2, and the rotating bolt 3 extends out of the lower surface of the rotating handle 4.

[0035] The height can be adjusted by adjusting the rotating handle 4 to drive the rotating bolt 3, which makes it convenient to adjust on the device and improves the applicability of the device.

[0036] Working principle: Before the multi-axis linkage mechanism 1 is operated, the multi-axis linkage mechanism 1 is pushed to a suitable position under the rolling support of the roller 5. Based on the threaded connection between the screw barrel 2 and the rotating bolt 3, the rotating bolt 5 is adjusted up and down in the height direction. The rotating bolt 3 is adjusted to drive the support base 9 toward the ground until the support base 9 contacts the ground. When the multi-axis linkage mechanism 1 starts to operate, the vibration-damping base 8 below reduces the impact of vibration during the operation of the multi-axis linkage mechanism 1.

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