Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to a swivel head device and a machining center. Background Technology

[0002] Medium and large machine tools must not only be able to meet multiple cutting processes but also ensure high machining accuracy. Therefore, the design, manufacturing, and assembly of machine tool components must ensure both functional diversity and the feasibility of high precision. For five-axis turning and milling composite machine tools with a large stroke, the swivel head component not only needs to achieve rotation at a certain angle but also needs to be mounted on the slide plate to achieve linear reciprocating motion. Therefore, the installation between the swivel head component and the slide plate component requires not only simple fixing but also attitude adjustment in at least two directions to ensure that the geometric accuracy of the assembled moving parts meets the finishing requirements throughout the entire stroke range.

[0003] CN101169976B discloses a high-precision adjustment fixture and its adjustment method, which can achieve adjustable precision positioning and installation of components in two directions. However, this positioning method poses significant manufacturing and operational difficulties for the assembly of large-tonnage, large-size swing head components. Furthermore, in order to achieve a compact design and ensure more processing space, the installation position of the swing head component is relatively compact, making it impossible to arrange multiple positioning and adjustment devices. Utility Model Content

[0004] The main purpose of this utility model is to provide a swivel head device and a machining center. This swivel head device can effectively solve the problems of installation and precision adjustment of large-size and heavy swivel heads, and realize the positioning and precision adjustment of the swivel head components during the installation process.

[0037] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0038] like Figures 1 to 4As shown, this utility model provides a swaying head device, including a swaying head component 1 and a swaying head connecting seat 2. The swaying head component 1 is fixedly connected to the swaying head connecting seat 2. The side of the swaying head connecting seat 2 connected to the swaying head component 1 is provided with an X-direction positioning surface 201, a Y-direction positioning surface 202, and a Z-direction positioning surface 203. The side of the swaying head component 1 connected to the swaying head connecting seat 2 is provided with an X-direction positioning mating surface 101 that mates with the X-direction positioning surface 201, a Y-direction positioning mating surface 102 that mates with the Y-direction positioning surface 202, and a Z-direction positioning mating surface 103 that mates with the Z-direction positioning surface 203. The multi-directional positioning surface and mating surface design provides a positioning reference for the swaying head component 1, enabling the swaying head component 1 to quickly and accurately align with the swaying head connecting seat 2 during installation, thereby improving installation efficiency.

[0039] During the installation of the oscillating head component 1, due to manufacturing errors, installation errors, and other factors, the initial installation position of the oscillating head component 1 may deviate to a certain extent in the X and Y directions. This invention further provides an X-direction adjustment structure 21 and a Y-direction adjustment structure 22 between the oscillating head connecting seat 2 and the oscillating head component 1. The X-direction adjustment structure 21 is used to adjust the positional accuracy of the oscillating head component 1 relative to the oscillating head connecting seat 2 in the X direction, achieving fine-tuning of the oscillating head component 1's position in the X direction; the Y-direction adjustment structure 22 is used to adjust the positional accuracy of the oscillating head component 1 relative to the oscillating head connecting seat 2 in the Y direction, achieving fine-tuning of the oscillating head component 1's position in the Y direction.

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, the swing head connecting seat 2 is provided with multiple X-direction threaded holes 211 along the X direction, and the swing head component 1 is also provided with multiple X-direction threaded connecting holes 111 along the X direction that mate with the X-direction threaded holes 211. The X-direction adjustment structure 21 is a bolt, which passes through the X-direction threaded holes 211 and the X-direction threaded connecting holes 111. By rotating the bolt, the positional accuracy of the X-direction positioning mating surface 101 of the swing head component 1 relative to the X-direction positioning surface 201 of the swing head connecting seat 2 can be adjusted. When the bolt is rotated clockwise or counterclockwise, due to the action of the thread, the bolt will move in the X-direction threaded holes 211 and the X-direction threaded connecting holes 111, causing the swing head component 1 to be displaced in the X direction. This achieves fine adjustment of the positional accuracy of the swing head component 1 in the X direction and timely compensation of errors, so as to meet the positional accuracy requirements of the swing head component 1 in the X direction under different working scenarios.

[0041] Similarly, such as Figure 1 and Figure 3As shown, the oscillating head connecting seat 2 is provided with multiple Y-direction threaded holes 221 along the Y direction, and the oscillating head component 1 is also provided with multiple Y-direction threaded connecting holes 121 that mate with the Y-direction threaded holes 221 along the Y direction. The Y-direction adjustment structure 22 is a bolt, which passes through the Y-direction threaded holes 221 and the Y-direction threaded connecting holes 121. By rotating the bolt, the positional accuracy of the Y-direction positioning mating surface 102 of the oscillating head component 1 relative to the Y-direction positioning surface 202 of the oscillating head connecting seat 2 can be adjusted. When the bolt is rotated clockwise or counterclockwise, due to the action of the thread, the bolt will move in the Y-direction threaded holes 221 and the Y-direction threaded connecting holes 121, causing the oscillating head component 1 to generate displacement in the Y direction. This achieves fine adjustment of the positional accuracy of the oscillating head component 1 in the X direction and timely compensation of errors, so as to meet the requirements of the positional accuracy of the oscillating head component 1 in the Y direction under different working scenarios.

[0042] like Figure 2 As shown, the X-direction threaded hole 211 is located on the side of the swing head connecting seat 2 away from the X-direction positioning surface 201, and the Y-direction threaded hole 221 is located on the side of the swing head connecting seat 2 close to the Y-direction positioning surface 202. There are at least four X-direction threaded holes 211, X-direction threaded connecting holes 111, Y-direction threaded holes 221, and Y-direction threaded connecting holes 121. At least two X-direction threaded holes 211 cooperate with the X-direction adjustment structure 21, or at least two Y-direction threaded holes 221 cooperate with the Y-direction adjustment structure 22 for the pushing action of the swing head connecting seat 2 on the swing head component 1. At least two X-direction threaded connecting holes 111 cooperate with the X-direction adjustment structure 21, or at least two Y-direction threaded connecting holes 121 cooperate with the Y-direction adjustment structure 22 for the tightening action of the swing head connecting seat 2 on the swing head component 1. This allows for adjustment of the swing head component 1 at multiple positions, reducing the possibility of excessive local force or uneven adjustment due to too few adjustment points.

[0043] In the above scheme, preferably, the four X-direction threaded holes 211 and the X-direction threaded connecting holes 111, when engaged with the X-direction adjustment structure 21, have different functions, respectively realizing the pushing and tightening functions of the upper and lower parts of the swing head component 1, such as... Figure 2 As shown, for example, there are four X-direction threaded holes 211 from top to bottom. The first one is used for pushing (when mated, the right side of the sway head component 1 is away from the connecting side of the sway head connecting seat 2). The second one is used for tightening (when mated, the sway head component 1 is close to the connecting side of the sway head connecting seat 2). The third one is used for pushing. The fourth one is used for tightening. Of course, there can be other combinations, such as the first one being used for pushing, the second one for tightening, the third one for tightening, and the fourth one for pushing. In short, as long as the positional accuracy adjustment in the X direction is achieved, it is acceptable.

[0044] Similarly, when the four Y-direction threaded holes 221, the four Y-direction threaded connecting holes 121, and the Y-direction adjustment structure 22 are engaged, their functions also differ, respectively realizing the pushing and tightening functions on the left and right sides of the swing head component 1, such as... Figure 2 As shown, for example, there are four Y-direction threaded holes 221 from left to right. The first one is used for pushing (when mated, the lower part of the sway head component 1 is away from the connecting side of the sway head connecting seat 2). The second one is used for tightening (when mated, the sway head component 1 is close to the connecting side of the sway head connecting seat 2). The third one is used for pushing. The fourth one is used for tightening. Of course, there can be other combinations, such as the first one being used for tightening, the second one for pushing, the third one for pushing, and the fourth one for tightening. In short, as long as the positional accuracy adjustment in the Y direction is achieved, it is acceptable.

[0045] like Figures 1 to 4 As shown, the Z-direction positioning surface 203 of the swing head connecting seat 2 and the Z-direction positioning mating surface 103 of the swing head component 1 are provided with matching fixing holes (not marked in the figure). The Z-direction positioning mating surface 103 and the Z-direction positioning surface 203 are fixedly connected by bolts passing through the fixing holes, thus fastening the Z-direction positioning mating surface 103 and the Z-direction positioning surface 203 together. This achieves a tight connection between the swing head component 1 and the swing head connecting seat 2 in the Z direction, reducing the displacement or loosening of the swing head component 1 in the Z direction due to movement in other directions, and improving the stability and reliability of the swing head device during operation.

[0046] like Figure 4 As shown, the side of the swing head connecting seat 2 away from the swing head component 1 is the mounting surface 23. The mounting surface 23 is provided with a lead screw nut connecting bracket 231, a fixed seat 232 and a guide structure 233. The lead screw nut connecting bracket 231 is used to fix and connect with the lead screw nut, so that the swing head connecting seat 2 can be connected to the lead screw transmission system (not shown in the figure) to realize the motion drive of the swing head device in a specific direction.

[0047] The fixed seats 232 are disposed on both sides of the mounting surface 23 of the swivel head connecting seat 2, and slide in cooperation with the guide rail on the machine tool's slide plate (not shown in the figure), realizing a slidable connection between the swivel head connecting seat 2 and the slide plate, providing linear motion support for the swivel head device along the guide rail direction. The guide structure 233 is disposed on the fixed seat 232 on at least one side of the mounting surface 23, and is used to limit the lateral offset of the swivel head connecting seat 2, so that the swivel head device can move smoothly along the guide rail direction, improving the overall motion accuracy and stability of the swivel head device.

[0048] like Figure 2As shown, the oscillating head connector 2 of this invention has an internal mesh-like hollow structure, which reduces the weight of the oscillating head connector 2 and thus reduces the overall weight of the oscillating head device. The oscillating head connector 2 is externally provided with a reinforcing rib structure 24, which enhances the overall strength of the oscillating head connector 2, improves its ability to withstand the impact forces generated during the movement of the oscillating head device, and maintains the structural integrity of the oscillating head connector 2. The internal mesh-like hollow structure and the external reinforcing rib structure 24 further synergistically improve the structural stability of the oscillating head connector 2.

[0049] Based on the aforementioned swivel head device, this utility model also provides a machining center, which includes the swivel head device described above.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
