[0002] In modern manufacturing processes, market demands for products are becoming increasingly diversified, making it difficult for single-specification machine tools to meet these needs. Reducing processes and improving work efficiency have inevitably become a trend, expanding the demand for milling-turning composite machine tools.

[0003] The saddle is a key component (support) of a milling and turning machine tool. The rationality of its structure and layout directly affects the machining accuracy and production efficiency of the machine tool.

[0004] How to develop a saddle that can be used with more turret models (such as hydraulic turrets, servo turrets, and power turrets) on the basis of the same machine model, while ensuring the commonality of key components, so as to provide more comprehensive functions and save the inconvenience caused by replacing the saddle, is an important issue in the design and manufacturing of machine tools. Utility Model Content

[0005] The purpose of this invention is to provide a machine tool saddle connection structure and a machine tool saddle to solve the problems mentioned in the background art. It can be used with more types of turrets, and when changing turrets, it can minimize the frequency of saddle disassembly and assembly, improving efficiency while saving a significant amount of time spent on precision calibration.

[0006] To solve the above-mentioned technical problems, on the one hand, this utility model provides a machine tool saddle connection structure, and the technical solution adopted is: include: The connecting plate has several fastening holes 1 extending through the thickness direction; the side of the connecting plate facing the slide plate on the machine tool saddle has several fastening holes 2 coaxially corresponding to the fastening holes, and the diameter of the fastening holes 2 is smaller than that of the fastening holes 1.

[0007] Preferably, both the first fastening hole and the second fastening hole are internal thread through holes.

[0008] Preferably, the connecting plate is provided with a plurality of fastening holes facing the turret direction.

[0009] Preferably, the third fastening hole is an internal thread blind hole and / or an internal thread through hole.

[0010] Preferably, the connecting plate is provided with a plurality of limiting holes.

[0011] Preferably, the limiting hole corresponds to the bolt hole on the slide plate.

[0012] On the other hand, this utility model also provides a machine tool saddle, the technical solution of which is: include: The saddle body is provided with a linear guide rail and a sliding seat slidably connected to the linear guide rail. A slide plate is fastened to the slide plate, and the slide plate performs linear reciprocating motion through a ball screw.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following is a summary description. Figure 1 To be continued Figure 6 The present invention will be further described in detail with reference to embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention. Example

[0019] This embodiment discloses a machine tool saddle connection structure that can be used with more types of turrets. When replacing the turret, the frequency of saddle disassembly and assembly can be reduced as much as possible, improving efficiency and saving a lot of time spent on precision calibration.

[0020] Its structure is simple and versatile, and it can be adapted to various configurations, such as mill-turn centers, vertical Y-axis, and virtual Y-axis. By using fewer structural types, it can meet a wider range of product requirements, reduce the number of machine tool parts, and simplify the production and management process.

[0021] refer to Figures 1 to 3 ,as well as Figure 6 Specifically, this includes: The connecting plate 100 has one side that fits against the slide plate on the machine tool saddle and the other side that fits against the turret, forming a clamped state on both sides. The connecting plate 100 has several through-holes 110 (specifically, internal threaded through holes) extending through its thickness. The side of the connecting plate 100 facing the slide plate 201 on the machine tool saddle has several coaxially corresponding fastening holes 111 (also internal threaded through holes), with the diameter of the second fastening holes 111 being smaller than that of the first fastening holes 110. These two coaxially corresponding holes (i.e., 110 and 111) can be connected to the turret and slide plate 201 respectively using bolt fastening connections.

[0022] This structure allows two bolts of different types to be coaxially aligned and fastened to different components. One bolt can be inserted into fastening hole 110 and threaded into fastening hole 111 and fastened to sliding seat 203, thereby connecting slide plate 201 and sliding seat 203. The other bolt is threaded into fastening hole 110, facilitating the connection of connecting plate 100 and slide plate 201.

[0023] Reference Appendix Figure 1 As shown, the above structure adds a connecting plate 100 to the original structure. This plate serves as a central connection and can be fixed to the slide plate 201 via fastening hole 110 (which serves to accommodate bolts) and fastening hole 111 (which serves to secure the connection). When installing different specifications of tool turrets, there is no need to disassemble the slide plate 201; only the connecting plate 100 needs to be replaced. This avoids the inconvenience of spending a lot of time scraping the slide plate 201 during disassembly and assembly, ensuring accuracy and greatly improving work efficiency. When connecting the tool turret 5, fastening hole 110 serves to secure the bolts, thus achieving a fixed connection with the tool turret 5.

[0024] In this embodiment, the connecting plate 100 is provided with a plurality of fastening holes 130 facing the turret 5. These connecting holes 130 can accommodate more specifications and models of turrets. Moreover, the fastening holes 130 can be internal thread blind holes, internal thread through holes, or both, depending on the specifications and models of the turret. Their relative positions and numbers can also be determined according to the specifications and models of the turret.

[0025] To achieve better positioning and improve connection efficiency, the connecting plate 100 is provided with several positioning holes 120, which correspond to the positioning blocks on the turret base. After the turret base is placed on the connecting plate 100, the positioning connection can be achieved by using the positioning blocks and positioning holes 120, eliminating the inconvenience of multiple people straightening and calibrating, reducing manual labor, and facilitating quick and easy tightening of bolts.

[0026] In addition, to ensure a stable connection while maximizing assembly and disassembly efficiency, the limiting hole 120 corresponds to the bolt holes 2011 on the sliding plate 201. Since there are multiple bolt holes 2011, and they correspond to the sliding seat 203, the limiting hole 120 can correspond to some of the bolt holes 2011, rather than all of them.

[0027] Specifically, refer to Figure 2 and Figure 3Since four sliding seats 203 are provided, the number of fastening holes 111 corresponding to each sliding seat 203 can be correspondingly increased or reduced appropriately. Furthermore, the limiting hole 120 matches the position of the un-fastening hole 111 (i.e., only matches the position of the bolt hole 2011). Thus, when disassembling and assembling the connecting plate 100, only the bolts on some of the fastening holes 111 need to be removed, eliminating the need to remove the bolts from the other bolt holes 2011. This ensures that the slide plate 201 and the sliding seat 203 remain connected while allowing for the disassembly and assembly of different connecting plates 100. In other words, when disassembling the connecting plate 100, the slide plate 201 and the sliding seat 203 remain firmly connected, improving efficiency and eliminating the tedious step of re-scraping and recalibrating after disassembling and assembling the slide plate 201. Example

[0028] refer to Figures 2 to 6 The purpose of this embodiment is to provide a machine tool saddle, and the technical solution adopted is: It includes a saddle body 3, which is provided with a linear guide rail 202 and a sliding seat 203 slidably connected to the linear guide rail 202. A slide plate 201 is fastened to the slide seat 203. The slide plate 201 performs linear reciprocating motion through a ball screw 204. A bearing seat unit 205 can be installed at the end of the ball screw 204.

[0029] The bolt holes 2011 on the slide plate 201 are coaxially corresponding to the aforementioned fastening holes 111 and are fastened together by fastening bolts. This structure is a common saddle, which assembles and connects the connecting plate 100 with a traditional machine tool saddle. The second fastening hole 111 is used to connect to the slide plate 201, and the first fastening hole 110 is used to connect to the base of the turret. The two are fixed together by bolts, such as in a hydraulic turret, servo turret, or power turret.

[0030] In addition, a virtual Y-axis trajectory can be added. The saddle body 3 is also provided with a virtual Y-axis slide plate 400 that is fixedly connected to the linear guide rail 202. The virtual Y-axis slide plate 400 is slidably connected to the second linear guide rail 401 provided on the saddle body 3 through the second sliding seat 402. The virtual Y-axis slide plate 400 performs linear reciprocating motion through the second ball screw 403. Of course, the second ball screw 403 is connected to the drive component (such as a servo motor).

[0031] A virtual Y-axis is a Y-axis form implemented through interpolation technology. It cannot achieve direct linkage between the X and Y axes; instead, it achieves functionality similar to a traditional orthogonal Y-axis by interpolating between the X and Y axes. In contrast, a conventional saddle structure only moves in the X direction. This difference in movement between conventional and virtual Y-axis saddle structures, resulting in parameter variations, is the main reason affecting the universality of saddle designs.

[0032] During installation, this utility model allows for the matching of different connecting plates 100 according to requirements, combining universal components with different parts to meet various configuration needs. The first configuration is a standard saddle (i.e., without a virtual Y-axis), such as... Figure 2 and Figure 3 The second configuration includes a virtual Y-axis, such as... Figure 4 and Figure 5 .

[0033] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: A connecting plate is added to the existing saddle body's slide plate, serving as a central support. Furthermore, the connecting plate has two coaxial fastening holes: fastening hole two aligns with bolt holes on the sliding seat, and fastening hole one aligns with bolt holes on the turret. When replacing a different turret, only the connecting plate needs to be removed; the entire slide plate does not need to be disassembled. The slide plate remains seamlessly connected to the sliding seat, eliminating the tedious scraping and adjustment process and improving efficiency.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
