Description

Technical Field

[0001] This utility model relates to the field of machine tools, and more specifically, to a machine tool body and a machine tool. Background Technology

[0002] In the field of modern machining, machine tools, as the core equipment for machining parts, directly affect the quality of industrial products and production efficiency. The machine tool body, as the basic structural component, directly impacts machining efficiency and product quality through its tool changing efficiency and tool management capabilities. In the multi-stage machining of complex parts, frequent tool changes and efficient tool management become key factors restricting production efficiency. The layout design of the machine tool's tool magazine and the collaborative performance of tool changing directly affect overall machining efficiency.

[0003] Currently, traditional machine tool bodies mainly adopt a single tool magazine layout or a symmetrical dual tool magazine layout. The single tool magazine layout has a long tool change path, low efficiency, and requires frequent tool loading and unloading, which greatly increases the tool change time and seriously affects the continuity of machining. Although the symmetrical dual tool magazine layout increases the tool reserve to some extent, the two tool magazines are usually symmetrically set on both sides or at the rear of the machine tool. Its tool change logic is essentially the same as that of the single tool magazine layout, and the optimization of the tool change path is limited. Utility Model Content

[0031] The following disclosure provides many different implementation methods or examples for different schemes of implementing this application.

[0032] On the one hand, such as Figures 1 to 3 As shown, this application embodiment provides a machine tool body. Figure 1As shown, the machine tool includes a base 1, a first column 2 and a second column 3 mounted on the base 1, a crossbeam 4 supported on the upper ends of the first column 2 and the second column 3, a spindle box 5 located on the front side of the crossbeam 4, and a spindle 6 housed within the spindle box. A guide rail surface 41 is formed at the front of the crossbeam 4, and the spindle box 5 is movably mounted on the guide rail surface 41. The base 1 serves as the basic support component of the machine tool body; the first column 2 and the second column 3 support the crossbeam 4, forming the frame structure of the machine tool and providing a mounting base for the crossbeam 4; the guide rail surface 41 at the front of the crossbeam 4 provides the mounting position for the spindle box 5 and supports its weight; the spindle box 5 is movably mounted on the guide rail surface 41 and contains the spindle 6, which drives the cutting tool to rotate and perform cutting operations.

[0033] Meanwhile, a first tool magazine 7 is located at the rear of the base 1, on the rear side of the vertical plane containing the guide rail surface 41. The rear space of the base 1 is relatively open and less susceptible to interference from the machining area, allowing the first tool magazine to store multiple types and quantities of tools to meet the multi-process machining needs of complex workpieces. A second tool magazine 8 is located on the side of the base 1, on the front side of the vertical plane containing the guide rail surface 41. It has a high degree of overlap with the spindle's movement path, resulting in a shorter spindle movement distance and enabling rapid tool changes. Each spindle 6 can cooperate with at least one first tool magazine 7 and one second tool magazine 8 for tool changes. By utilizing the non-machining areas at the front and rear of the base 1 to respectively arrange the second and first tool magazines, a dual improvement in tool storage capacity and tool changing efficiency is achieved without increasing the machine tool's footprint. This significantly enhances the machining efficiency and adaptability of the machine tool, making it particularly suitable for the multi-process machining needs of complex parts and large-scale batch production requirements.

[0034] like Figures 1 to 3 As shown, the first tool magazine 7 includes a tool magazine base plate 71 and a first tool magazine body 72. The first tool magazine body 72 is disposed on the tool magazine base plate 71, which supports the tool magazine body 72. A tool magazine moving component 9 is disposed above the base 1 along the front-rear direction of the base 1. The first tool magazine 7 is disposed above the tool magazine moving component 9. The first tool magazine 7 can move from the rear side of the guide rail surface 41 to below the spindle 6 via the tool magazine moving component 9. In the initial position in the unprocessed state, the first tool magazine 7 is located on the rear side of the vertical plane where the guide rail surface 41 is located, that is, the non-processing area at the rear of the machine tool, and will not interfere with the normal processing of the spindle 6. When it is necessary to use the first tool magazine 7 to change tools, the first tool magazine 7 moves forward to directly below the spindle 6 through the drive of the tool magazine moving component 9. At this time, the tool changing port of the tool magazine body 72 is aligned with the spindle axis, thereby realizing tool changing. The first tool magazine 7 actively moves to below the spindle 6 instead of the spindle 6 moving extensively, reducing the lateral idle travel of the spindle 6 and shortening the tool change path. This is especially suitable for the rapid change of heavy-duty tools. In the non-tool change state, the first tool magazine 7 is located at the rear of the base, without occupying machining area space, making the machine tool layout more compact.

[0035] like Figure 3 As shown, the tool magazine moving component 9 includes a first tool magazine guide rail 91, a tool magazine support platform 92 mounted on the first tool magazine guide rail 91, and a drive mechanism 93 for driving the tool magazine support platform 92. The tool magazine base plate 71 is fixed on the tool magazine support platform 92, realizing high-precision and high-reliability movement of the first tool magazine 91. This provides a compact and efficient solution for the machine tool body tool changing system, and is especially suitable for heavy-duty tool storage and rapid tool changing needs, significantly improving the machining efficiency of the machine tool body.

[0036] In some embodiments, the first tool magazine 7 can also be fixed to the rear of the base 1, without occupying machining area space. A tool reserve mechanism is provided on the base 1 or the first tool magazine 7. This mechanism ensures accurate tool positioning and reliable clamping, establishes a motion trajectory between the first tool magazine 7 and the spindle 6, and installs the tools from the first tool magazine 7 onto the spindle 6. The first tool magazine 7 is fixed to the rear of the machine tool, and the tool reserve mechanism is provided on the base 1 or the first tool magazine 7, without occupying additional machining area space. The tool reserve mechanism independently undertakes the tool handling task, avoiding large-scale movement of the spindle 6 and reducing positioning errors caused by spindle 6 movement.

[0037] In some implementations, the bottom of the first tool magazine 7 is provided with multiple mounting holes, and the corresponding rear part of the base 1 is provided with threaded holes. The first tool magazine 7 is fastened to the base 1 by bolts. While ensuring the rigidity and positioning accuracy of the connection between the first tool magazine 7 and the base 1, the ease of installation is also taken into account, providing a reliable and flexible solution for production.

[0038] like Figure 3 As shown, the second tool magazine 8 includes a tool magazine bracket 81 and a second tool magazine body 82. The second tool magazine body 82 is mounted on the tool magazine bracket 81, and the tool magazine bracket 81 provides mechanical support for the second tool magazine body 82.

[0039] like Figure 2 As shown, the tool magazine support 81 includes a tool magazine base 811 and a support arm 812. The tool magazine base 811 and the support arm 812 are integrally formed to maintain the overall rigidity of the tool magazine support 81. The support arm 812 is inclined and tilted upwards away from the base 1, so that the second tool magazine body 82 is suspended above or to the side of the machine tool body working area, avoiding interference with components such as the worktable and spindle 6. This is especially suitable for scenarios where multiple tool magazines work together.

[0040] In some implementations, the first tool magazine 7 is a chain-type tool magazine, suitable for storing large-capacity tools and capable of holding heavy tools. A tool changing port is located on the front side of the chain-type tool magazine near the spindle 6. The second tool magazine 8 is a disc-type tool magazine, with a tool changing port on the side near the spindle 6, allowing for fast tool changing. The first tool magazine 7 and the second tool magazine 8 are spatially separated to avoid interference, forming a multi-directional layout at the rear and sides of the base, expanding the tool storage range. The chain-type tool magazine of the first tool magazine 7 and the disc-type tool magazine of the second tool magazine 8 respectively address the needs for large capacity and rapid tool changing, covering various types of tools and providing differentiated solutions for different tool characteristics. This reduces the number of downtime tool changes due to insufficient tools, reduces invalid tool changing paths, and avoids concentrating on the same area of ​​space, maximizing tool capacity within a limited space. Their collaborative operation significantly improves the machining flexibility and production efficiency of the machine tool, making it particularly suitable for complex parts machining scenarios requiring multiple processes and multiple tool types.

[0041] In some embodiments, two spindle boxes 5 and a spindle 6 are provided on the front side of the crossbeam 4. Two first tool magazines 7 and two second tool magazines 8 are included. The two first tool magazines 7 are arranged side-by-side behind the base 1, and the two second tool magazines 8 are located on the sides of the first column 2 and the second column 3, respectively. One spindle 6 cooperates with one of the first tool magazines 7 and 8 on one side, and the other spindle 6 cooperates with the first tool magazine 7 and 8 on the other side. Each spindle box 5 can move independently up and down along the guide rail surface 41 of the crossbeam 4 to achieve cutting depth control. The two spindles can move synchronously or asynchronously to cooperate with the first or second tool magazine for tool changing. The two spindles 6, the two first tool magazines 7, and the two second tool magazines 8 can simultaneously execute different machining programs. For example, when one spindle 6 is changing tools with the first tool magazine 7, the other spindle 6 can simultaneously change tools with the second tool magazine on the same side and enter the machining state, achieving time overlap and greatly improving machining efficiency, especially suitable for batch production scenarios with multiple processes and multiple tools.

[0042] On the other hand, this application also provides a machine tool. In some embodiments of this application, the machine tool includes a Y-axis motion component 10, a worktable 11 disposed on the Y-axis motion component 10, and a machine tool body as described in one of the preceding embodiments. The Y-axis motion component 10 of the machine tool body is disposed on a base 1, and the working end of the spindle 6 faces the worktable 11. Since the machine tool has the aforementioned machine tool body, it also has the corresponding effects of the machine tool body, which will not be described again here.

[0043] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
