X-axis slide of a machine tool and side-hung gantry mobile machine tool

Abstract

This utility model discloses an X-axis slide block for a machine tool and a side-mounted gantry-type moving machine tool, including a slide block body. The slide block body has an arched groove on the side away from the gantry of the machine tool and multiple slider mounting surfaces on both sides of the arched groove. The slider mounting surfaces on the same side are arranged parallel to the X-axis direction. This ensures that the arched bottom of the arched groove can significantly strengthen the original double-wall structure, thereby improving the ability to resist forward and backward bending. This can resist the forward tilting moment exerted by the gantry of the machine tool on the X-axis slide block and prevent the X-axis slide block from undergoing severe bending deformation.

Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to an X-axis slide and a side-mounted gantry moving machine tool. Background Technology

[0002] A side-mounted gantry moving machine tool refers to a machine tool whose worktable is fixed and whose gantry moves forward and backward along the X-axis. There is an X-axis slide on the left and right sides of the gantry, and a side-mounted machine head is mounted on the gantry.

[0003] Currently, most X-axis slides adopt a double-wall structure, that is, the upper and lower walls are parallel to each other. If a side-mounted machine head is used, the gantry will have a forward tilting moment acting on the double-wall structure of the X-axis slide. However, due to the insufficient rigidity of the double-wall structure for the forward tilting moment, the X-axis slide is prone to severe bending deformation. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an X-axis slide for a machine tool and a side-mounted gantry-type moving machine tool, which can resist the forward tilting torque applied by the gantry frame to the X-axis slide, thereby preventing severe bending deformation of the X-axis slide.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model provides an X-axis slide for a machine tool, including a slide body. The bottom surface of the slide body is provided with an arched groove and multiple slider mounting surfaces located on both sides of the arched groove. The arrangement direction of the slider mounting surfaces on the same side is parallel to the X-axis direction.

[0007] Furthermore, the cross-sectional shape of the arched groove perpendicular to the X-axis is an isosceles trapezoid.

[0008] Furthermore, the arched groove extends through two opposing surfaces of the slide body in the X-axis direction; the slide body is provided with vertical ribs for rigidly supporting the groove wall of the arched groove.

[0009] This utility model provides a side-mounted gantry moving machine tool, including a machine tool bed, a gantry frame, a machine head mounted on the gantry frame, and an X-axis slide of the machine tool; the gantry frame is slidably mounted on the machine tool bed through the X-axis slide.

[0010] Furthermore, the X-axis slide has a first segment and a second segment distributed along its X-axis direction, and a mating surface is provided between the second segment and the gantry frame. The length of the X-axis slide in the X-axis direction is greater than the length of the mating surface in the X-axis direction.

[0011] Furthermore, the center of gravity of the machine head corresponds to the first segment, and the center of gravity of the gantry corresponds to the second segment.

[0012] Furthermore, at least three sets of sliders are provided between the bottom surface of the machine tool bed and the X-axis slide. The first set of sliders is located at the end of the first segment away from the second segment, the second set of sliders and the third set of sliders are located at the two ends of the second segment in the X-axis direction, and the second set of sliders is located between the first set of sliders and the third set of sliders. The center of gravity of the machine head is located between the first set of sliders and the second set of sliders, and the center of gravity of the gantry is located between the second set of sliders and the third set of sliders.

[0013] The technical solution provided by this utility model has the following beneficial effects:

[0014] By providing an arched groove to the slide body, the arched bottom of the groove can significantly enhance the strength of the original double-wall structure, thereby improving the ability to resist forward and backward bending. This can resist the forward tilting moment applied by the machine tool gantry to the X-axis slide and prevent the X-axis slide from undergoing severe bending deformation. Attached Figure Description

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] Reference Figure 1 Embodiment 1 provides an X-axis slide (hereinafter referred to as X-axis slide) for a machine tool, which can be used as the X-axis slide of a side-mounted gantry moving machine tool.

[0022] The X-axis slide in this embodiment includes a slide body 100, which naturally has a double-wall structure that is in the prior art.

[0023] The slide body 100 has an arched groove 3 on its bottom surface away from the gantry of the machine tool, and multiple slider mounting surfaces 4 located on the left and right sides of the arched groove 3. The slider mounting surfaces 4 on the same side are arranged in a direction parallel to the X-axis, which is the front and back direction.

[0024] In this embodiment, the arched groove 3 penetrates the two front and rear opposing surfaces of the slide body 100 in the X-axis direction.

[0025] By providing an arched groove 3 to the slide body 100, the arched bottom of the arched groove 3 can significantly strengthen the original double-wall structure, thereby improving its ability to resist forward and backward bending. This can resist the forward tilting moment applied by the gantry to the X-axis slide and prevent the X-axis slide from undergoing severe bending deformation.

[0026] In another preferred embodiment, the cross-sectional shape of the arched groove 3 perpendicular to the X-axis direction is an isosceles trapezoid.

[0027] More specifically, the slide body 100 is provided with vertical ribs 5 for rigidly supporting the groove wall of the arched groove 3. That is, multiple vertical ribs 5 are fixedly connected between the upper bottom wall and the two waist sides of the arched groove 3 and the top of the slide body 100, so as to play the role of reinforcing ribs.

[0028] Of course, in other embodiments, the cross-sectional shape of the arched groove 3 may also be semi-circular, horseshoe-shaped, or other arc-shaped.

[0029] Example 2

[0030] like Figure 2 and Figure 3 As shown, Embodiment 2 provides a side-mounted gantry moving machine tool, including a machine tool bed, a gantry frame, a machine head mounted on the gantry frame, and an X-axis slide block as described in Embodiment 1. The gantry frame is slidably mounted on the machine tool bed via the X-axis slide block.

[0031] In this embodiment, the slide body 100 of the X-axis slide has a first segment 1 and a second segment 2 distributed along its X-axis direction, that is, the first segment 1 and the second segment 2 are arranged in front and back and connected to each other, and the arched groove 3 passes through the first segment 1 and the second segment 2 in the front and back directions respectively.

[0032] like Figure 2 As shown, a joint surface 21 is provided between the top of the second segment 2 and the gantry frame, and the gantry frame is fixed to the joint surface 21 located at the top of the second segment 2.

[0033] The length of the X-axis slide in the X-axis direction is greater than the length of the mating surface 21 in the X-axis direction. At this time, the center of gravity of the machine head corresponds to the first segment 1, and the center of gravity of the gantry corresponds to the second segment 2.

[0034] More specifically, three sets of sliders are provided between the machine tool bed and the X-axis slide on the bottom side of the slider mounting surface 4, and three sets of slider mounting surfaces are provided accordingly. Each set of slider mounting surfaces includes two slider mounting surfaces arranged on the left and right opposite each other.

[0035] The first set of sliders is located at the front end of the first segment 1 away from the second segment 2, that is, the first set of sliders corresponds to the first set of slider mounting surface 41.

[0036] The second and third sets of sliders are located at the front and rear ends of the second segment 2 in the X-axis direction, respectively, and the second set of sliders is located between the first and third sets of sliders. At this time, the second set of sliders corresponds to the second set of slider mounting surface 42, and the third set of sliders corresponds to the third set of slider mounting surface 43.

[0037] By positioning the center of gravity of the machine head between the first and second sets of sliders and the center of gravity of the gantry between the second and third sets of sliders, the dynamic and static load bearing stability of the slide body 100 is ensured.

[0038] Of course, in other embodiments, the number of slider groups can also be four or five or more, depending on the size and structural design of the X-axis slider.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
