[0008] Secondly, by setting the relative position and state between the connecting part, the rotation axis of the first motor and the rotation axis of the second motor, not only can the torque load caused by adjusting the angle change of the first motor and the second motor be reduced, that is, the angle adjustment is more sensitive and convenient, but also the position angle change trajectories of the first motor and the second motor are partially overlapped, so as to greatly reduce interference in the change process, thereby reducing space occupancy and making the structure more streamlined.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The embodiment of the present application discloses a combined engraving processing device.

[0038] Reference Figure 1 and Figure 2, the engraving combination processing device includes a mounting frame 1, a connecting member 2, a first motor 3, a second motor 5, and a rotation driving assembly 6. Among them, the mounting frame 1 serves as the mounting base, which is used to mount the engraving combination processing device onto the engraving multi-axis machining center.

[0039] In this embodiment, the mounting frame 1 includes two ear plates 11. The two ear plates 11 are arranged oppositely, and the two ear plates 11 are fixedly connected by a mounting plate 12. The mounting plate 12 is used to be mounted onto the engraving multi-axis machining center. That is, the overall shape of the mounting frame 1 is an inverted "U" shape. In other embodiments, the mounting frame 1 can also be of other shapes.

[0040] In order to reduce the self-weight, the mounting frame 1 can also be made into a hollow structure.

[0041] In this embodiment, the connecting member 2 includes two first connecting plates 21 and two second connecting plates 22. The two first connecting plates 21 are arranged oppositely, and the two second connecting plates 22 are arranged oppositely. The first connecting plate 21 and the second connecting plate 22 are fixed to each other. That is, the connecting member 2 in this embodiment is of a square structure. The second connecting plate 22 is rotatably connected to the ear plate 11 of the mounting frame 1. The rotation driving assembly 6 is used to drive the second connecting plate 22 to rotate to change the angle of the second connecting plate 22. The rotation driving assembly 6 can be a servo motor or a combination of a servo motor and a speed reducer to perform more precise angle adjustment.

[0042] In other embodiments, the connecting member 2 can be of other shapes, as long as it can meet the functions of torque transmission and installation position; and the mounting frame 1 needs to leave a certain clearance space to reduce the rotational interference of the connecting member 2. In this embodiment, it is achieved by increasing the length of the ear plate 11.

[0043] The first motor 3 is used to drive the engraving tool 31 to rotate, and the second motor 5 is used to drive the saw blade 51 to rotate. Both the engraving tool 31 and the saw blade 51 are detachable. According to different working conditions, only the saw blade 51 or the engraving tool 31 can be used, or different-sized saw blades 51 or engraving tools 31 can be replaced. And if the saw blade 51 is disassembled, the flexibility of the engraving process can be increased to a certain extent.

[0044] In this embodiment, the first motor 3 and the second motor 5 are respectively mounted on the two first connecting plates 21, so that the rotation axes of the first motor 3 and the second motor 5 are not on the same straight line, and the rotation axis of the connecting member 2 is located between the rotation axes of the first motor 3 and the second motor 5. That is, the rotation axis of the connecting member 2 is arranged skew to the rotation axes of the first motor 3 and the second motor 5 respectively.

[0045] Furthermore, the positional relationship between the rotation axes of the connecting member 2, the first motor 3 and the second motor 5 can be that the rotation axis of the first motor 3 and the rotation axis of the second motor 5 are parallel. In other embodiments, the rotation axis of the first motor 3 and the rotation axis of the second motor 5 may not be parallel to each other. For example, the first motor 3 can be installed on one of the first connecting plates 21, and the second motor 5 is installed on the top of the connecting member 2, so that the rotation axis between the second motor 5 and the first motor 3 is 90 degrees.

[0046] The rotation axis of the connecting member 2 may also be arranged perpendicularly to the rotation axis of the first motor 3 in an eccentric plane.

[0047] Furthermore, the center of gravity positions of the first motor 3 and the second motor 5 may be further limited to further reduce the torque load.

[0048] The common perpendicular line between the rotation axis of the first motor 3 and the rotation axis of the connecting member 2 is set as the first common perpendicular line, and the intersection point between the first common perpendicular line and the rotation axis of the first motor 3 is set as the first intersection point; the center of gravity of the first motor 3 is located within a virtual spherical range with the first intersection point as the center of the sphere and the length of the first common perpendicular line as the radius.

[0049] The common perpendicular line between the rotation axis of the second motor 5 and the rotation axis of the connecting member 2 is set as the second common perpendicular line, and the intersection point between the second common perpendicular line and the rotation axis of the second motor 5 is set as the second intersection point; the center of gravity of the second motor 5 is located within a virtual spherical range with the second intersection point as the sphere center and the length of the second common perpendicular line as the radius.

[0050] That is, by setting the center of gravity position of the first motor 3 and the second motor 5, the center of gravity of the first motor 3 and the second motor 5 is controlled at an appropriate position to reduce the torque load caused by adjusting the angle change of the first motor 3 and the second motor 5, that is, the angle adjustment is more sensitive and convenient.

[0051] In this embodiment, the output shaft direction of the first motor 3 is the same as the output shaft direction of the second motor 5, that is, the saw blade 51 and the engraving tool 31 can be on the same side to facilitate the replacement of the saw blade 51 or the engraving tool 31. In other embodiments, the saw blade 51 and the engraving tool 31 can be on opposite sides or in different directions to suit different application conditions.

[0052] like Figure 3 As shown, the first motor 3 and the second motor 5 can be respectively installed with the connecting member 2 by welding or by bolting. In this embodiment, a detachable installation method of bolting is adopted.

[0053] Furthermore, in order to increase applicability, the first connecting plate 21 is provided with at least two mounting points 23 , and the mounting points 23 are through-holes for bolts to pass through, so as to install the first motor 3 and the second motor 5 .

[0054] Moreover, the mounting points 23 are arranged at intervals along the rotation axis direction of the first motor 3 or the second motor 5. By installing the motors at different mounting points 23, the positions of the motors can be fine-tuned to adapt to different processing heights, different sizes of engraving knives 31 or saw blades 51, different torque load adjustments, etc., thereby improving the applicability of the overall equipment.

[0055] In order to increase safety, a saw blade guard 7 can be added. In the present embodiment, a vertical plate 71 is fixed to the saw blade guard 7. The vertical plate 71 is fixed to the side of one of the first connecting plates 21 relative to the other first connecting plate 21 by bolts, so that the center of gravity of the saw blade guard 7 is closer to the rotation axis of the connecting member 2, thereby reducing the eccentric moment to reduce the torque load.

[0056] like Figure 4 As shown, this embodiment also discloses an engraving machining center, which includes the above-mentioned engraving combination processing device and a machining center body 10, the mounting frame 1 is arranged on the gantry of the machining center body 10 or on other transmission mechanisms of the gantry, and the machining center body 10 can be a three-axis, four-axis, five-axis or six-axis machining equipment.

[0057] The implementation principle of this embodiment is: by integrating the first motor 3 and the second motor 5 onto the same connecting member 2, using the mounting frame 1 and the rotation drive assembly 6 to control the rotation of the connecting member 2, so as to control the angles of the engraving knife 31 and the saw blade 51, so as to be able to switch to the engraving or cutting state respectively, so as to process the stone material on the same processing station, without moving the stone material again, eliminating the need for re-positioning, thereby improving the processing efficiency.

[0058] Secondly, by setting the relative position and state between the connecting member 2, the rotation axis of the first motor 3 and the rotation axis of the second motor 5, not only the angle adjustment is more sensitive and convenient, but also the position angle change trajectories of the first motor 3 and the second motor 5 are partially overlapped, so as to greatly reduce the interference in the change process and thus reduce the space occupancy rate.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
