Description

Technical Field

[0001] This utility model relates to the field of horizontal five-axis machine tool technology, and in particular to a horizontal five-axis machine tool. Background Technology

[0002] In existing technologies, the core of horizontal five-axis machining centers for achieving precision machining of complex curved surfaces and spatial angles lies in having two additional rotary degrees of freedom. Currently, these two key rotary axes, namely the B-axis and C-axis, are generally highly integrated into a single cradle-type rotary table mechanism. While this integrated design simplifies the overall layout of the horizontal five-axis machine tool to some extent, concentrating the dual rotary motion functions within a single structural unit inevitably leads to an exceptionally complex internal structure of the cradle mechanism and weakens its rigidity to some extent, making it prone to deformation and vibration when subjected to cutting loads.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The following is combined with Figure 1 and Figure 2 This invention describes a horizontal five-axis machine tool provided in an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0028] An embodiment of this utility model provides a horizontal five-axis machine tool, such as... Figure 1 and Figure 2 As shown, it includes: a bed 100; a linear sliding mechanism disposed on the bed 100; a milling head mechanism 300 connected to the linear sliding mechanism; a B-axis rotation mechanism 400 connected to the milling head mechanism 300 and used to drive the milling head mechanism 300 to rotate along the B-axis; and a C-bearing load rotation mechanism 500 disposed on the bed 100 and used to carry the workpiece and drive the workpiece to rotate along the C-axis.

[0029] The horizontal five-axis machine tool provided by this utility model includes a bed 100, a linear sliding mechanism, a milling head mechanism 300, a B-axis rotation mechanism 400, and a C-bearing-loaded rotation mechanism 500. The linear sliding mechanism is disposed on the bed 100 and connected to the milling head mechanism 300, which is capable of milling workpieces. The linear sliding mechanism drives the milling head mechanism 300 to slide linearly. The B-axis rotation mechanism 400 is connected to the milling head mechanism 300 and drives the milling head mechanism 300 to rotate along the B-axis. The C-bearing-loaded rotation mechanism 500 is also disposed on the bed 100, which carries the workpiece and drives it to rotate along the C-axis.

[0030] As described above, by independently integrating the B-axis rotary mechanism 400 into the milling head mechanism 300 to drive its rotary motion along the B-axis direction, and simultaneously setting the C-bearing rotary mechanism 500 separately on the bed 100 to directly carry the workpiece and drive its rotation, the physical separation of the dual rotary motion functions is achieved. This significantly simplifies the structure of the horizontal five-axis machine tool and avoids the structural complexity of the existing integrated cradle mechanism. At the same time, the C-bearing rotary mechanism 500 has a simple structure and is fixed to the bed 100 base, which greatly improves its rigidity and stability and effectively reduces the deformation and vibration phenomena under cutting force load.

[0031] In one embodiment of the present invention, the linear sliding mechanism includes: a first slide rail 210, which is disposed on the bed 100 along the X-axis direction; a slide block 220, which is slidably connected to the first slide rail 210; a second slide rail, which is disposed on the slide block 220 along the Y-axis direction; and a milling head mechanism 300 slidably connected to the second slide rail.

[0032] Furthermore, in one embodiment of the present invention, the slide block 220 includes: a slide block plate 221, which is slidably connected to a first slide rail 210; a first base 222, which is connected to one end of the slide block plate 221 and protrudes outward from the side away from the first slide rail 210; and a second base 223, which is connected to the other end of the slide block plate 221 and protrudes outward from the side away from the first slide rail 210.

[0033] The second slide rail includes: a first side rail 231, which is disposed on the first base 222 along the Y-axis; a second side rail 232, which is disposed on the second base 223 along the Y-axis; and a milling head mechanism 300 slidably connected between the first side rail 231 and the second side rail 232.

[0034] In another embodiment of the present invention, the linear sliding mechanism further includes: a first driving mechanism 240, which is connected to the slide plate 221 and is used to drive the slide plate 221 to slide along the first slide rail 210; and a second driving mechanism 250, which is connected to the milling head mechanism 300 and is used to drive the milling head mechanism 300 to slide along the second slide rail.

[0035] For example, such as Figure 1 and Figure 2 As shown, the first slide rail 210 includes three spaced X-axis tracks. The bottom of the slide plate 221 has three X-axis grooves that correspond to each X-axis track. Each X-axis groove is slidably connected to each X-axis track. A first base 222 and a second base 223 are respectively provided at both ends of the slide plate 221. Alternatively, the slide plate 221, the first base 222, and the second base 223 together constitute a C-shaped slide 220 structure. A first side rail 231 is provided on the first base 222 along the Y-axis, and a second side rail 232 is provided on the second base 223 along the Y-axis. The first side rail 231 and the second side rail 232 are symmetrically arranged about the central axis of the slide plate 221 in the Y-axis direction. The milling head mechanism 300 is slidably connected between the first side rail 231 and the second side rail 232. This improves the support rigidity of the slide 220 and the force balance of the milling head mechanism 300, thereby improving the machining accuracy of the horizontal five-axis machine tool.

[0036] The first drive mechanism 240 can drive the slide plate 221 to move along the first slide rail 210, that is, to move along the X-axis. The second drive mechanism 250 can drive the milling head mechanism 300 to move along the second slide rail, that is, to move along the Y-axis. Both the first drive mechanism 240 and the second drive mechanism 250 are linear drive mechanisms, including, but not limited to, hydraulic cylinders and pneumatic cylinders.

[0037] In one embodiment of the present invention, the milling head mechanism 300 includes: a base 310, which is slidably connected between a first side rail 231 and a second side rail 232; a third slide rail 320, which is disposed on the base 310 along the Z-axis direction; and a milling head body 330, which is slidably connected to the third slide rail 320.

[0038] In one embodiment of the present invention, the milling head mechanism 300 further includes: a sliding connector 350, which is slidably connected to a third slide rail 320, and the milling head body 330 is connected to the sliding connector 350.

[0039] Furthermore, in one embodiment of the present invention, the milling head mechanism 300 further includes a third driving mechanism 340, which is connected to the sliding connector 350 and is used to drive the sliding connector 350 to slide along the third slide rail 320.

[0040] In another embodiment of the present invention, the B-axis rotation mechanism 400 is connected to the milling head body 330 and is used to drive the milling head body 330 to rotate along the B-axis direction.

[0041] For example, such as Figure 1 and Figure 2 As shown, two Y-axis sliding grooves are provided at the bottom of the base 310, respectively adapted to the first side rail 231 and the second side rail 232. The base 310 is slidably connected to the first side rail 231 and the second side rail 232 through the Y-axis sliding grooves. The second drive mechanism 250 is connected to the base 310 to drive the base 310 to slide along the second sliding rail in the Y-axis direction. A third sliding rail 320 is provided on the base 310 along the Z-axis direction. A sliding connecting body 350 is slidably connected to the third sliding rail 320. The third drive mechanism 340 is connected to the sliding connecting body 350 to drive the sliding connecting body 350 to move along the third sliding rail 320, that is, along the Z-axis direction. The milling head body 330 is connected to the sliding connecting body 350. The milling head body 330 can mill the workpiece on the C-bearing rotating mechanism 500. The B-axis rotating mechanism 400 is connected to the milling head body 330 and is used to drive the milling head body 330 to rotate along the B-axis direction. The B-axis rotary mechanism 400 includes, but is not limited to, a rotary motor.

[0042] In another embodiment of the present invention, the C-bearing rotating mechanism 500 includes: a first support column 510 connected to the bed 100; a second support column 520 connected to the bed 100, and the second support column 520 and the first support column 510 are spaced apart along the X-axis direction; and a workpiece support table 530 rotatably connected between the first support column 510 and the second support column 520.

[0043] In one embodiment of the present invention, the C-axis bearing rotation mechanism 500 further includes a C-axis rotation mechanism 540, which is connected to the workpiece support platform 530 and is used to drive the workpiece support platform 530 to rotate along the C-axis direction.

[0044] like Figure 1As shown, the C-axis rotary mechanism 500 is located on the front side of the linear sliding mechanism. A first support column 510 and a second support column 520 are spaced apart on the bed 100, and a workpiece carrier 530 is rotatably connected between the first support column 510 and the second support column 520. The first support column 510 and the second support column 520 are spaced apart along a direction parallel to the X-axis, so that the workpiece carrier 530 is positioned parallel to the X-axis. The C-axis rotary mechanism 540 is connected to the workpiece carrier 530 to drive the workpiece carrier 530 to rotate along the C-axis direction. The C-axis rotary mechanism 540 includes, but is not limited to, a rotary motor.

[0045] During workpiece machining, the first drive mechanism 240 adjusts the X-axis position of the milling head body 330, the second drive mechanism 250 adjusts the Y-axis position of the milling head body 330, and the third drive mechanism 340 adjusts the Z-axis position of the milling head body 330. The B-axis rotation mechanism 400 adjusts the B-axis rotation position of the milling head body 330. The C-axis rotation mechanism 540 adjusts the C-axis rotation position of the workpiece on the workpiece carrier 530, thereby achieving five-axis machining of the workpiece. By separating the linear motion axes from the rotary motion axes, the accumulation of shape errors at the tool tip can be avoided.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
