Description

Technical Field

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

[0002] The spindle box of a machine tool is a crucial component for mounting the spindle. The spindle moves up and down along the column, enabling machining operations on the spindle within it. The spindle box bears the weight of numerous components. Currently, the spindle box is directly mounted on a guide rail on the column and slides along it. This method causes long-term friction between the spindle box and the guide rail, leading to wear on both the spindle box and the guide rail. Therefore, the connection method between the spindle box and the column has shortcomings and needs improvement. Utility Model Content

[0003] To address the aforementioned problems, the present invention aims to provide a spindle box and machine tool to solve the technical problem of wear caused by the spindle box sliding directly on the guide rail.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model provides a spindle box and machine tool, comprising: a housing and a slider, wherein the housing is provided with a mounting surface, and a plurality of slider mounting structures are provided on the mounting surface, the plurality of slider mounting structures being arranged vertically on both sides of the mounting surface, each side of the mounting surface having at least two slider mounting structures, and the slider mounting structures on both sides of the mounting surface being symmetrically arranged; each slider mounting structure is connected to a slider for sliding connection with a column guide rail, and the slider is detachably connected to the slider mounting structure.

[0006] In some embodiments, each side of the mounting surface has three slider mounting structures, the three slider mounting structures are equidistantly arranged in a vertical direction, and the slider is connected to the slider mounting structure by connecting bolts.

[0007] In some embodiments, at least one of the plurality of slider mounting structures is provided with a guide structure, which is a vertically extending box guide rail provided on the slider mounting structure, and the box guide rails are all located on the same side of the mounting surface.

[0008] In some embodiments, the housing is provided with a vertically penetrating cylindrical cavity, which is located on the side of the housing away from the mounting surface, and the cylindrical cavity is used to mount the spindle.

[0009] In some embodiments, the box body is provided with a cavity, the cavity is provided with reinforcing ribs, and the cylindrical cavity is located in the cavity; the reinforcing ribs are arranged between the surface of the cavity and the cylindrical cavity, and the reinforcing ribs are arranged in a crisscross pattern.

[0010] In some embodiments, the enclosure includes a vertical structure and a box structure perpendicular to the vertical structure, the mounting surface is located on the vertical structure, and the reinforcing rib is located inside the box structure;

[0011] The lower end of the vertical structure is provided with an extension structure that extends away from the box structure. An inclined support structure is provided between the extension structure and the box structure, and the inclination angle of the support structure is 30°-60°.

[0012] In some embodiments, the housing has a hollowed-out structure on the side away from the mounting surface, and the cylindrical cavity is located within the hollowed-out structure.

[0013] In some embodiments, the outer side of the box structure is provided with multiple weight-reducing hole structures.

[0014] In some embodiments, the upper end face of the box is provided with an opening structure, which is an oblong hole.

[0015] A machine tool includes a column and a spindle box as described in any one of the above claims. A column guide rail is provided on the column, and the spindle box is slidably mounted on the column guide rail via the slider.

[0016] Another aspect of this utility model provides a machine tool, including a column and a spindle box as described above. A column guide rail is provided on the column, and a slider that matches a slider mounting structure is provided on the column guide rail. The spindle box is slidably mounted on the column guide rail through the matching connection between the slider mounting structure and the slider.

[0017] The beneficial effects of this utility model are as follows: Multiple slider mounting structures for mounting sliders are provided on the mounting surface of the housing. The housing is slidably mounted on the guide rail on the column via these slider mounting structures. In actual use, the sliders slide directly relative to the guide rail, and the weight of the spindle box is also borne by the sliders. Because the sliders and housing are detachable structures, and the sliders are detachably connected to the column guide rail, when the sliders wear out, they can be replaced, reducing wear on the housing. Furthermore, because the sliders on each side of the mounting surface are separate structures, different sliders can be replaced according to the worn parts; simultaneously, the separate slider structure helps reduce the overall weight of the spindle box.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] refer to Figure 1 and Figure 4 One aspect of this utility model provides a spindle box, comprising: a housing 1, a mounting surface 2 for assembly with a column guide rail, a plurality of slider mounting structures 3 arranged vertically on both sides of the mounting surface 2, each side of the mounting surface 2 having at least two of the slider mounting structures 3, and the slider mounting structures 3 on both sides of the mounting surface 2 being symmetrically arranged; each slider mounting structure 3 is configured to be connected to a slider 4 for sliding connection with the column guide rail, and the slider 4 is detachably connected to the slider mounting structure 3.

[0026] Multiple slider mounting structures 3 are provided on the mounting surface 2 of the housing 1 for mounting sliders. The housing 1 is slidably mounted on the guide rail on the column via the slider mounting structures 3. In actual use, the sliders slide directly relative to the guide rail, and the weight of the spindle box is also borne by the sliders 4. Because the sliders 4 and the housing 1 are detachable structures, and the sliders 4 are detachably connected to the column guide rail, when the sliders 4 wear out, they can be replaced, reducing wear on the housing 1. In addition, because the sliders 4 on each side of the mounting surface 2 are separate structures, different sliders 4 can be replaced according to the worn parts; at the same time, the separate slider structure helps to reduce the weight of the entire spindle box.

[0027] In some embodiments, each side of the mounting surface has three slider mounting structures 3, which are equidistantly arranged vertically. The sliders 4 are connected to the slider mounting structures 3 by connecting bolts. Three slider mounting structures are provided on each side of the mounting surface, and each slider mounting structure has one slider, ensuring that the connection between the two sides of the mounting surface and the column guide rail has a supporting force.

[0028] In some implementations, reference Figure 1 and Figure 4 Among the multiple slider mounting structures 3, at least one is equipped with a guide structure 6, which serves as a positioning guide for mounting the housing 1 onto the column guide rail. Further, the guide structure 6 is a vertically penetrating box guide rail on the slider mounting structure 3. Specifically, in actual operation, the slider 4 is first slidably mounted on the column guide rail, and then the housing 1 is mounted onto the column 12 through the assembly of the slider mounting structure 3 and the slider 4. The slider mounting structure 3 and the slider 4 are fixedly connected, allowing the housing 1 to move up and down along the column guide rail via the slider 4. The slider mounting structure 3 has protruding strips on both sides, arranged vertically to form a vertically penetrating box guide rail. This penetrating box guide rail is assembled with the column guide rail, which is located between the two protruding strips, allowing the slider 4 to move up and down along the column guide rail.

[0029] In some implementations, reference Figure 1 and Figure 4 The box guide rails (guide structure 6) are all located on the same side of the mounting surface 2. Specifically, since the box guide rails serve a guiding and positioning function, the protruding box guide rails may cause interference when assembling the box body 1 and the slider 4, i.e., the box guide rails may contact the column guide rails. If box guide rails are installed on both sides of the slider mounting structure 3 on the mounting surface 2, it would be detrimental to guidance. Therefore, by installing the box guide rails on the same side of the mounting surface 2, when assembling the box body 1 and the slider 4, only the box guide rail on the mounting surface 2 needs to mate with the column guide rail. In addition, installing box guide rails on the slider mounting structure 3 on one side of the mounting surface 2 can also improve processing efficiency.

[0030] In some implementations, reference Figure 1 and Figure 2 The housing 1 has a vertically penetrating cylindrical cavity 5 located on the side away from the mounting surface 2. The cylindrical cavity 5 is used to mount the spindle. Specifically, the cylindrical cavity 5 has a through circular hole in the middle. The spindle is installed in the circular hole and passes through it. The spindle is located in the circular hole, and the cylindrical cavity 5 provides protection for the spindle.

[0031] In some implementations, reference Figure 1 and Figure 3 The housing 1 contains a cavity with reinforcing ribs 7 inside. A cylindrical cavity 5 is located within the cavity. The reinforcing ribs 7 are arranged between the surface of the cavity and the outer surface of the cylindrical cavity 5. Specifically, the reinforcing ribs 7 are positioned between the inner wall of the cavity and the outer wall of the cylindrical cavity 5, meaning the reinforcing ribs 7 support or abut against the inner wall of the cavity and the outer wall of the cylindrical cavity 5, thus enhancing the overall strength of the housing 1. Further, the reinforcing ribs 7 are arranged in a crisscross pattern, or in a cross-shaped structure. This cross-shaped structure provides support to the housing 1 from the inside from four directions: top, bottom, left, and right. Alternatively, a horizontal plate and a vertical plate are arranged between the horizontal plate and the inner surface of the housing 1. The vertical plate abuts against the horizontal plate and the inner surface of the housing 1 to enhance the strength of the housing 1. (Refer to...) Figure 3 .

[0032] In some implementations, reference Figure 1 , Figure 2 and Figure 3 The housing 1 includes a vertical structure 8 and a box structure 9 perpendicular to the vertical structure 8. The mounting surface 2 is located on the vertical structure 8, and the reinforcing ribs 7 are located inside the box structure 9. Specifically, the vertical structure 8 can be a plate structure, and the box structure 9 is perpendicular to this plate structure. The lower end of the vertical structure 8 has an extension structure that extends away from the box structure 9; that is, both the upper and lower ends of the vertical structure 8 extend away from the box structure 9, so that both sides of the vertical structure 8 extend beyond the corresponding surfaces of the box structure 9.

[0033] An inclined support structure 10 is provided at the junction of the extension structure and the box structure 9. This support structure 10 extends from one side of the extension structure to the lower surface of the box structure 9, with one end abutting against the extension structure and the other end abutting against the surface of the box structure 9, providing support for the vertical structure 8 and the box structure 9. Existing spindle boxes have virtually no space at the bottom, leaving no room for the tool changing structure. In this invention, the support structure 10 is set as an inclined structure, with space between the inclined surface of the inclined structure and the spindle position, which can be used for the rotational positioning of the tool changing structure. The inclination angle of the support structure 10 is 30°-60° (refer to direction 2 here). Preferably, the inclination angle is 45°.

[0034] In some implementations, reference Figure 1 and Figure 2 The housing 1 has a hollowed-out structure on the side away from the mounting surface 2, and the cylindrical cavity 5 is located inside the hollowed-out structure. Specifically, the hollowed-out structure is set on the side of the housing structure 9 away from the slider mounting structure 3 to reduce the overall weight of the housing 1. The cylindrical cavity 5 is located at the hollowed-out structure, and while reducing weight, the cylindrical cavity 5 structure still provides protection for the spindle.

[0035] In some implementations, reference Figure 1 The upper surface of the housing 1 is provided with an opening structure 11, which is generally rectangular in shape like a racetrack, or the opening structure 11 is an oblong hole. The top-view projection circular hole of the cylindrical cavity 5 is located within the opening structure 11. The opening structure 11 facilitates the installation of the spindle structure and also reduces the weight of the housing 1.

[0036] Furthermore, a number of weight-reducing hole structures 13 communicating with the interior of the box 1 are provided on the side of the box 1. These weight-reducing hole structures 13 effectively reduce the overall weight of the box 1.

[0037] refer to Figure 1 and Figure 4 Another aspect of this utility model provides a machine tool, including a column and a spindle box of any of the above. A guide rail is provided on the column, and a slider that matches the slider mounting structure 3 is provided on the guide rail. Through the matching connection between the slider mounting structure 3 and the slider, the spindle box can be slidably mounted on the guide rail.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
