[0004] As a first aspect of the embodiments of this application, the embodiments of this application provide a frame of a five-axis machine tool, including:

[0005] Base

[0006] The two opposing side support seats are fixed to the base to form a support structure for supporting the main shaft and the sliding mechanism for driving the main shaft to slide. The side support seats are provided with through holes that pass through the side support seats and are used to support the cradle mechanism. The side support seats include at least two sub-seats distributed vertically, and the at least two sub-seats are fixedly connected by threads.

[0007] In one embodiment, at least two sub-seats include a first sub-seat and a second sub-seat from top to bottom, with the second sub-seat being integrally formed with the base.

[0008] In one embodiment, a through hole is provided in the first sub-seat.

[0009] In one embodiment, the first sub-seat is provided with a plurality of first protrusions, and the second sub-seat is provided with a first recess corresponding to the position of the first protrusions, and the first protrusions and the first recesses engage with each other.

[0011] In one embodiment, the first protrusion is at least one of a square protrusion, an arc-shaped protrusion, and an S-shaped protrusion.

[0012] In one embodiment, the first protrusion includes a plurality of first partial protrusions and at least one second partial protrusion; the spacing between the plurality of first partial protrusions is equal; the spacing between the second partial protrusion and an adjacent first partial protrusion is greater than the spacing between the plurality of first partial protrusions.

[0013] In one embodiment, a through hole is disposed between a first portion protrusion and an adjacent second portion protrusion.

[0014] As a second aspect of the present application, the present application provides a five-axis machine tool, including a cradle mechanism, a spindle, a sliding mechanism for driving the spindle to slide, and the machine body of the five-axis machine tool in any of the above embodiments; the cradle mechanism is mounted in the through hole of the side support plate in the machine body.

[0015] The technical solution of this application embodiment uses a split design of at least two sub-seats for the side support base, which makes each sub-seat more rigid, less prone to bending and deformation, and easier to install, resulting in a more stable installed body.

[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0022] Figure 1 A schematic diagram of the structure of the frame of a five-axis machine tool according to an embodiment of this application is shown. Figure 2 An exploded structural diagram of the frame of a five-axis machine tool according to an embodiment of this application is shown. Figure 3 A schematic diagram of a five-axis machine tool according to an embodiment of this application is shown. Figures 1 to 3 As shown, the five-axis machine tool's body includes a base 100 and two opposing side support seats 200 disposed on the base 100. The base 100 stands on the ground; the higher the base 100, the more stable the machine body is during the five-axis machine tool's machining process. The side support seats 200 are fixed to the base 100, forming a support structure for supporting the spindle 500 and the sliding mechanism 300 that drives the spindle 500 to slide; the side support seats 200 are provided with through holes 201 penetrating the side support seats 200, and the through holes 201 are used to support the cradle mechanism 400; the side support seats 200 include at least two sub-seats distributed vertically, and the at least two sub-seats are fixedly connected by threads.

[0023] The technical solution of this application embodiment uses a split design of at least two sub-seats for the side support seat 200, which makes each sub-seat have better rigidity, is not easy to bend or deform, and is easy to install, so that the installed body has stronger stability.

[0024] In one example, an operation window 212 can be set near the adjacent sub-seats to fix the two adjacent sub-seats together by screwing them from the top and bottom direction, or vertical direction, or which can be understood as the Z-axis.

[0025] By connecting multiple sub-seats to form a whole side support seat 200, good rigidity can be maintained during the processing of the sub-seats, and the middle of the support seat will not bend or soften due to the overall height of the side support seat 200 being too high.

[0026] In one embodiment, at least two sub-seats include a first sub-seat 210 and a second sub-seat 220 from top to bottom, with the second sub-seat 220 integrally formed with the base 100.

[0027] The height of the second sub-base 220 can be less than the height of the base 100, or 1 / 4 to 1 / 4 of the height of the base 100. The second sub-base 220 is located close to the base 100 and needs to have a very stable fixed connection with the base 100, thereby ensuring the stability of the connection through integral molding. Since the base 100 is relatively wide, even if it is integrally molded with the second sub-base 220, there will be no situation such as bending in the middle.

[0028] The height of the second sub-seat 220 can be based on the height that is not easily bent or deformed when integrally formed with the base 100.

[0029] In one embodiment, a through hole 201 is provided in the first sub-seat 210.

[0030] In this embodiment, the cradle mechanism 400 passes through two opposing through holes 201 and is mounted on the through holes 201. The height of the through holes 201 needs to match the required height of the cradle mechanism 400. The through holes 201 are set on the first sub-base 210, making the through holes 201 a single, integral through hole 201 on the first sub-base 210. The height of the second sub-base 220 needs to maintain a certain rigidity, and its height will not be very high. If the through holes 201 are set on the second sub-base 220, the diameter of the through holes 201 would be large, affecting the height design of the second sub-base 220. Furthermore, if the height of the second sub-base 220 is not high, with half of the through holes 201 on the first sub-base 210 and half on the second sub-base 220, the through holes 201 would not be strong enough, and the first sub-base 210 and the second sub-base 220 would separate during repeated rotation of the cradle. Therefore, it is necessary to set the through holes 201 on a single, complete sub-base, such as the first sub-base 210. The first sub-base 210 is located on the side of the second sub-base 220 away from the base 100, and its height is sufficient to allow the through hole 201 to be installed.

[0031] In one embodiment, the first sub-seat 210 is provided with a plurality of first protrusions 221, and the second sub-seat 220 is provided with a first recess corresponding to the position of the first protrusions 221, and the first protrusions 221 engage with the first recess.

[0032] By providing multiple first protrusions 221 on the first sub-base 210, the upper part of the first sub-base 210 has a toothed structure that meshes with the first recess on the second sub-base 220.

[0033] In one embodiment, it can be understood that the second sub-seat 220 is provided with a plurality of second protrusions 211, and the first sub-seat 210 is provided with a second recess 222 at the position corresponding to the second protrusions 211, and the second protrusions 211 and the second recesses 222 engage with each other; the length of the second protrusions 211 is greater than the length of the first protrusions 221.

[0034] In this embodiment, by interlocking two adjacent seats, lateral movement between the seats can be further prevented, thus further ensuring the stability of the fuselage.

[0035] In one embodiment, the first protrusion 221 is at least one of a square protrusion, an arc-shaped protrusion, and an S-shaped protrusion.

[0036] The aforementioned square protrusion, arc protrusion, and S-shaped protrusion can be understood as the cross-sectional shape along the extension direction of the first protrusion 221.

[0037] It is understandable that the shape of the first notch that engages with the first protrusion 221 is adapted to the shape of the first protrusion 221.

[0038] It is understandable that, relatively speaking, the lateral movement resistance of the seat is better with arc-shaped protrusions than with directional protrusions; and the lateral movement resistance of the seat is better with S-shaped protrusions than with arc-shaped directional protrusions.

[0039] In one embodiment, the first protrusion 221 includes a plurality of first portion protrusions 2212 and at least one second portion protrusion 2211; the spacing between the plurality of first portion protrusions 2212 is equal; the spacing between the second portion protrusion 2211 and the adjacent first portion protrusion 2212 is greater than the spacing between the plurality of first portion protrusions 2212.

[0040] The first protrusion 2212 can be understood as the first protrusion 221 on the longer side of the through hole 201; the second protrusion 2211 can be understood as the first protrusion 221 on the shorter side of the through hole 201.

[0041] In one embodiment, a through hole 201 is disposed between a first portion protrusion 2212 and an adjacent second portion protrusion 2211. The distance between the first portion protrusion 2212 and the adjacent second portion protrusion 2211 is relatively wide, allowing the dome of the through hole 201 to be located at the protruding position of the second protrusion 211. This fully utilizes the space of the first portion 210, providing a location to accommodate the through hole 201 within a limited height. It also avoids a decrease in rigidity caused by an excessively high first portion height.

[0042] As a second aspect of the present application, the present application provides a five-axis machine tool, including a cradle mechanism 400, a spindle 500, a sliding mechanism 300 for driving the spindle 500 to slide, and the machine body of the five-axis machine tool in any of the above embodiments; the cradle mechanism 400 is mounted in the through hole 201 of the side support plate in the machine body.
