Referring to fig. 1 and 3, an embodiment of the present invention provides a five-axis machine 10, where the five-axis machine 10 includes a machining turntable 200, and the machining turntable 200 is mounted on a machining turntable mounting structure. The processing turret 200 further comprises a loading table 210 for loading the workpiece to be processed, the loading table 210 being rotatably arranged on the processing turret 200. The processing turntable mounting structure can move along X, Y, Z three directions, and then drives the processing turntable 200 to move along X, Y, Z three directions. The loading platform 210 is rotatably mounted on the processing turntable 200, thereby realizing five-axis linkage. This five-axis machine 10 uses the processing revolving stage mounting structure to install processing revolving stage 200, can reach the purpose that reduces five-axis machine 10 and install size in the Z axle direction through processing revolving stage mounting structure.
Preferably, the loading table 210 is disposed toward the Z-axis, and the loading table 210 is perpendicular to the rotation center axis 260 of the processing turntable 200.
As for the processing turret mounting structure, specifically, referring to fig. 2, 3 and 4, the processing turret mounting structure includes a bottom plate 100 for mounting a processing turret 200, the bottom plate 100 is provided with a through opening 110, the processing turret 200 is rotatably disposed above the opening 110, a bottom of the processing turret 200 at least partially extends into the opening 110, the processing turret 200 has a preset rotation stroke, and the processing turret 200 is spaced from a periphery of the opening 110 during rotation. It should be noted that, in another embodiment, the bottom plate 100 may be provided with only a non-through groove (not shown), which functions similar to the through opening 110, and the bottom of the processing turntable 200 also at least partially extends into the non-through groove.
It should be understood that the preset rotation stroke may be understood as a maximum rotation angle of the processing turntable 200, including forward rotation and reverse rotation. In this embodiment, the bottom of the processing turret 200 is partially installed to extend into the opening 110, and when the processing turret 200 rotates forward or backward to the maximum rotation angle, the outer contour of the bottom of the processing turret 200 and the periphery of the opening 110 are not in contact collision all the time, thereby ensuring that the processing turret 200 can work normally.
In this processing turret mounting structure, through set up opening 110 on bottom plate 100 to at least some stretches into in opening 110 with the bottom of processing revolving stage 200, so, effectively reduced the height of the rotation center axle 260 of processing revolving stage 200, make the installation size of processing revolving stage 200 in the Z axle direction reduce, and then reduced the requirement to the Z axle stroke of machine tool, be convenient for match miniature machine tool.
Preferably, the bottom of the processing turret 200 has an arc-shaped portion 230, an axial direction of the arc-shaped portion 230 is disposed parallel to a rotation center axis 260 of the processing turret 200, and the arc-shaped portion 230 is disposed toward the rotation center axis 260. The whole or part of the bottom of the processing turntable 200 is made into the arc-shaped portion 230, and compared with the processing turntable 200 with the plane bottom, under the condition of the same width of the opening 110, the arc-shaped portion 230 allows the pointing opening 110 to extend deeper, that is, compared with the case that the bottom of the arc-shaped portion 230 is the plane, the arc-shaped portion 230 is more beneficial to reducing the size in the Z-axis direction, and further more beneficial to realizing the compact design of the five-axis machine 10, so as to adapt to a small-sized processing machine tool to a greater extent.
Further, the bottom of the processing turret 200 further has a first end surface 240 and a second end surface 250 disposed toward the rotation center shaft 260, both ends of the arc part 230 are respectively connected to opposite side surfaces of the first end surface 240 and the second end surface 250, and the first end surface 240 and the second end surface 250 are perpendicular to the axial direction of the arc part 230. By disposing the first end surface 240 and the second end surface 250 to be perpendicular to the rotation center axis 260 of the processing turret 200, it is possible to reduce a required reserved space between both side portions of the processing turret 200 and both end portions of the opening 110 as much as possible. The first and second end surfaces 240 and 250 are horizontally spaced from the peripheries of both end portions of the opening 110 while the processing turret 200 rotates about the rotation center shaft 260. In this way, a compact design of five-axis machine 10 in the horizontal direction is facilitated.
Preferably, the opening 110 is configured to be rectangular, and the opposite sides of the first end face 240 and the second end face 250 each have a first preset gap from the periphery of the opening 110. It should be understood that the first predetermined gap is provided to prevent the two end portions of the processing turret 200 from interfering with the periphery of the opening 110 when the processing turret rotates. Moreover, since the first end surface 240 and the second end surface 250 are perpendicular to the rotation center axis 260 of the processing turret 200, it is beneficial to set the first preset gap to be small, specifically, the interference does not occur when the processing turret 200 rotates, and the smaller the first preset gap is, the better the first preset gap is. As such, in the present embodiment, the length dimension of the processing turret 200 in the upward direction along the rotation center axis 260 is smaller than the dimension of the opening 110 in the longitudinal direction.
In some embodiments, the arc portion 230 is an arc member, and a small gap is left between the arc and two sides of the opening 110 along the rotation center axis 260. The central axis of the arc-shaped portion 230 coincides with the rotation central axis 260 of the processing turntable 200, and the outer contour of the arc-shaped portion 230 always keeps a constant gap with the two side portions of the opening 110 along the rotation central axis 260 direction within a preset rotation stroke, so that the width dimension of the arc-shaped portion 230 can be set as large as possible (i.e. the projection of the arc-shaped portion 230 on the bottom plate 100, the width of the arc-shaped portion is as close to the width of the opening 110 as possible), and a very small gap is reserved between the outer contour of the arc-shaped portion 230 and the opening 110, thereby being beneficial to increasing the depth of the arc-shaped portion 230 penetrating into the opening 110.
In other embodiments, the arc 230 is formed by connecting a plurality of folded surfaces in sequence. It is to be understood that the arcuate portion 230 at this point may be part of a polygonal body, preferably a regular polygonal body. Compared with the arc-shaped part 230, the structure is beneficial to the installation of the parts inside the processing turntable 200.
Preferably, in order to maximize the extension of the arc-shaped part 230 into the opening 110, in some embodiments, the edge of the arc-shaped member is equal to the gap on both sides of the opening 110. In other embodiments, the circular edge inscribed by the folds of the plurality of folds is equal to the gap on both sides of the opening 110.
Further, the arc-shaped part 230 is detachably mounted at the bottom of the processing turntable 200, so that the arc-shaped part 230 is convenient to disassemble and assemble, and maintenance is convenient. When maintenance is required, the processing turret 200 is rotated so that the arc portion 230 faces upward for easy attachment and detachment.
At the same time, the projected contour of the arc 230 in at least one rotational position falls within the opening 110. The arc 230 is projected onto the base plate 100 such that the projection of the arc 230 falls just inside the opening 110. The width of the arc-shaped portion 230 is limited, which is beneficial to achieve better penetration of the arc-shaped portion 230 into the opening 110, and further reduce the height of the rotation center shaft 260 to the maximum.
In this embodiment, the arc portion 230 is fixedly coupled to the bottom of the processing turret 200 by bolts.
Referring to fig. 5, the processing turret 200 further includes a belt driving mechanism 220, the belt driving mechanism 220 being disposed near the bottom of the processing turret 200 along a rotation center axis 260 of the processing turret 200, and the loading table 210 being disposed above the belt driving mechanism 220 and rotating in synchronization with a driven wheel of the belt driving mechanism 220. The belt transmission mechanism 220 drives the loading platform 210 to rotate, which is more beneficial to reducing the assembly size of the processing turntable 200 in the Z-axis direction compared with a worm gear transmission mode.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
