Description

Technical Field

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

[0002] Traditional milling and turning machines have the following mechanical structural challenges when switching between tailstock and subspindle functions, whether or not a Y-axis module is configured, and when switching between servo and hydraulic tailstocks:

[0003] 1. Lack of mechanical interchangeability between tailstock and sub-spindle functional modules: The tailstock and sub-spindle of existing machine tools adopt completely independent mechanical architectures, which makes the two functional modules unable to be directly replaced. Because the tailstock and sub-spindle are designed with different mechanical interface standards and transmission systems, they cannot be directly used interchangeably. When the production demand changes from the tailstock function of supporting the workpiece to the sub-spindle function of realizing workpiece rotation processing, a large-scale modification of the machine tool is required, including replacing basic components and rewiring, which is not only time-consuming and labor-intensive, but also seriously affects the continuity of production.

[0004] 2. The existing straight Y-axis module configuration can be converted, but it suffers from mechanical performance degradation: Machine tools with a Y-axis use a stacked cross slide structure (straight Y, also called orthogonal Y-axis structure). When switching to a configuration without a Y-axis, the dynamic stiffness decreases significantly (the straight Y-axis slide weighs about 200kg, causing the center of gravity of the X-axis slide to shift upwards, and the top of the straight Y-axis to be suspended, thus affecting the rigidity of the equipment). There is also a spatial layout conflict (with a straight Y-axis, the turret installation position needs to be moved upwards to avoid the straight Y-axis slide; without a Y-axis, the 150mm height space occupied by the original Y-axis slide becomes an idle area, which needs to be filled with additional protective devices, increasing the structural complexity).

[0005] 3. Replacement is equivalent to major redesign, requiring redesign of castings and sheet metal, resulting in low efficiency and high cost: Replacement of traditional machine tools is equivalent to major redesign, requiring redesign of castings and sheet metal. The integration of different functional modules depends on castings and sheet metal parts with specific structures. When it is necessary to replace or add functional modules, such as when switching tail-end functions or adjusting the configuration of Y-axis modules, it is necessary to redesign and manufacture castings and sheet metal to adapt to them. This process involves complex design calculations, mold development and processing and manufacturing, which is time-consuming and costly. This makes it difficult for enterprises to respond quickly when facing diversified production needs, and greatly restricts production efficiency and market competitiveness.

[0006] Based on the above, this application proposes a modular CNC interpolation Y-axis machine tool. Summary of the Invention

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular CNC interpolation Y-axis machine tool.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A modular CNC interpolation Y-axis machine tool includes a bed, a spindle unit mounting area on the top left side of the bed, a first spindle unit mounted on the spindle unit mounting area, a high rail on the top rear side of the bed, and a low rail on the top front side of the bed. Z1 saddle and Z2 saddle are fixedly mounted on the high rail and the low rail, respectively.

[0010] Preferably, a secondary spindle unit is mounted and fixed on the top of the Z2 saddle.

[0011] Preferably, a tail top unit is fixedly installed on the top of the Z2 saddle.

[0012] Preferably, a Y-axis slide saddle is mounted on the top of the Z1 slide saddle, an X-axis slide plate is mounted on the Y-axis slide saddle, and a power turret is mounted on the X-axis slide plate.

[0013] Preferably, a servo turret is mounted on the X-axis slide plate.

[0014] Preferably, the X-axis slide plate can also be fixedly installed on the top of the Z1 slide saddle.

[0015] Compared with existing technologies, the beneficial effects of this utility model are:

[0016] By using the bed, Z1 saddle, Z2 saddle and first spindle unit as fixed references, standardized mechanical interfaces can be established and uniform specifications can be designed, enabling the tailstock-sub-spindle functional modules to be quickly interchanged without rewiring or large-scale modification of basic components, greatly shortening the function conversion time and ensuring production continuity.

[0017] By setting the Y-axis slide saddle, the straight Y-axis of the stacked cross slide structure can be changed to an interpolated Y-axis structure, abandoning the rigid stacking layout of the traditional straight Y-axis, avoiding the problem of the center of gravity shifting upward due to the self-weight of the straight Y-axis slide, effectively improving the dynamic stiffness of the equipment. At the same time, since the independent Y-axis slide is eliminated, the contradiction of spatial layout is resolved, the idle area is reduced, no additional protective device is required, and the structural complexity is reduced.

[0018] By adopting a modular design concept, the casting sheet metal of the machine tool is designed in a universal way, and the main structure of the machine tool is divided into multiple functionally independent modular units. The modules are connected through standardized interfaces. When changing functional modules, only the corresponding functional modules need to be replaced, without redesigning the overall structure of the casting sheet metal. For example, when switching the tailstock function or adjusting the Y-axis module configuration, only the corresponding functional module components need to be replaced, which greatly shortens the design and manufacturing cycle, reduces costs, and improves the enterprise's response speed to diversified production needs.

[0019] This invention, through a series of structural designs, establishes standardized mechanical interfaces and unified specifications, enabling rapid interchangeability of the tailstock-sub-spindle functional modules. It transforms the straight Y-axis of the stacked cross slide structure into an interpolated Y-axis structure, abandoning the rigid stacked layout of the traditional straight Y-axis and avoiding the problem of the center of gravity shifting upwards due to the weight of the straight Y-axis slide, thus resolving spatial layout conflicts. Furthermore, through the modular design, when replacing functional modules, only the corresponding functional module needs to be replaced, without redesigning the overall cast sheet metal structure, significantly shortening the design and manufacturing cycle, reducing costs, and improving the enterprise's responsiveness to diversified production needs.
