Description

Technical Field

[0001] The utility model relates to the field of machine tool equipment, in particular to a crane gantry machine tool column. Background Art

[0002] The casting structure of traditional gantry machine tools is mainly box-type structure (i.e. box-type structure). This structure is suitable for uniform load bearing and has a short design and production cycle. However, the load bearing capacity of the uniform structure is usually directional, and the structural strength is positively correlated with the cost. For the columns of overhead crane gantry machine tools (especially large overhead crane gantry machine tools), the overall shape is elongated along its length, the load transmitted from the moving parts is heavy and concentrated, and the working conditions are complex. Many traditional cast iron columns are not rigid enough when carrying heavy loads, and are prone to deformation, which affects the machining accuracy of the machine tools. Therefore, it is necessary to redesign a column suitable for overhead crane gantry machine tools. Utility Model Content

[0003] Therefore, the utility model provides a column for a gantry machine tool to improve the above problems.

[0006] Furthermore, the overhead crane gantry machine column has a first side facing the gantry machine and a second side away from the gantry machine in the width direction; the first sides of the base, support column and support beam are flush; the second side of the base protrudes from the second side of the support beam.

[0007] Furthermore, the support column includes a lower part connected to the base and an upper part connected to the support beam in the height direction, and the second side of the upper part is flush with the second side of the support beam; the second side of the lower part is an inclined surface to transitionally connect the upper part and the base.

[0008] Furthermore, the multiple groups of support columns include two groups of outer support columns located on the outermost sides and at least one group of middle support columns located in the middle, and the outer support columns are larger in length than the middle support columns; reinforcing ribs are provided on the second side of the middle support columns.

[0009] Furthermore, the base is composed of a grid-like reinforcement structure.

[0010] Furthermore, the grid-shaped reinforcement structure is a "well" - shaped structure formed by the staggered connection of longitudinal beams extending in the length direction and cross beams extending in the width direction.

[0011] Furthermore, bowl-shaped cavities for splicing are formed on the two outer sides of the column of the overhead crane gantry machine tool in the length direction.

[0012] Furthermore, first reinforcing ribs are provided on the two side surfaces of the support column in the length direction, and first reinforcing ribs are also provided on the two side surfaces of the base and the support beam in the length direction.

[0013] Furthermore, the cross-section of the support beam is a "concave" - shaped structure, and the two sides in the width direction bulge upward to form tracks; a second reinforcing rib is formed between the bottom of the support beam and the connected support column.

These drawings are a part of the disclosure of the present utility model, which are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible embodiments and the advantages of the present utility model. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] In the description of the present invention, the orientation or positional relationships such as "upper", "lower", "left", "right", "front", "rear", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0025] Now, the present utility model will be further described in combination with the drawings and specific embodiments.

[0026] Referring to Figures 1 to 6 As shown, a column of an overhead gantry machine tool provided in this embodiment includes a base 10, a support column 20, and a support beam 30 that are integrally cast. That is, the base 10, the support column 20, and the support beam 30 are integrally cast, and specifically, they can be formed by lost foam casting. The base 10 is a continuous structure extending along the length direction (i.e., the X-axis direction), and multiple groups (specifically, four groups) of the support columns 20 are provided and are spaced along the length direction on the base 10; the support beam 30 is a continuous structure extending along the length direction and is provided on the tops of the four groups of support columns 20; in this way, a bridge-type structure is formed; among the four groups of support columns 20, the two outermost groups of support columns 20 (defined as the outer support columns 201) are flush with the ends of the base 10 and the support beam 30 and jointly serve as the side walls of the column of the overhead gantry machine tool, and the two middle groups of support columns 20 (defined as the middle support columns 202) support at the middle position of the support beam 30. The width of the base 10 is greater than that of the support beam 30, which can provide stable support; a track 31 extending along the length direction is provided on the top of the support beam 30 for the slide to move.

[0027] This solution adopts an integrally cast bridge-type structure, which can bear heavy loads to cope with complex working conditions, and the overall deformation amount is relatively small during the movement of the slide. Moreover, compared with the existing box-type structure, the column of this bridge-type structure can effectively reduce the volume while improving the bearing capacity.

[0028] Further preferably, in this embodiment, the column of the overhead gantry machine tool has a first side 101 facing the gantry machine tool and a second side 102 facing away from the gantry machine tool in the width direction; the first sides of the base 10, the support columns 20 and the support beam 30 are flush to ensure that the upper and lower door widths of the overhead gantry machine tool are the same for subsequent assembly of the structure; the second side of the base 10 protrudes from the second side of the support beam 30 to ensure support.

[0029] As a structure connecting the base 10 and the support beam 30, the support column 20 includes a lower part 22 connecting the base 10 and an upper part 21 connecting the support beam 30 in the height direction. The second side of the upper part 21 is flush with the second side of the support beam 30; the second side of the lower part 22 is an inclined surface to transitionally connect the upper part 21 and the base 10. Of course, in other embodiments, the second side of the support column 20 can also directly be an inclined surface connecting the support beam 30 to the base 10.

[0030] Among the four groups of support columns 20 in this embodiment, the sizes of the two outermost groups of support columns 20 (i.e., the outer support columns 201) in the length direction are larger than those of the two middle groups of support columns 20. For this reason, reinforcing rib plates 23 are provided on the second side of the two middle groups of support columns 20 (i.e., the middle support columns 202); specifically, two reinforcing rib plates 23 are connected to the second side of each group of middle support columns 202. The reinforcing rib plate 23 is a triangular plate, with two sides respectively connecting the upper part 21 and the lower part 22, and the third side being the connection line between the second side of the support beam 30 and the second side of the base 10. The structure of setting the reinforcing rib plates 23, on the one hand, strengthens the support force of the extended part of the middle support columns 202, and on the other hand, maintains the bearing capacity balance with the two outermost groups of lengthened support columns 20 (i.e., the outer support columns 201). Of course, in other embodiments, the four groups of support columns 20 can also be of equal size structures, and the reinforcing rib plates 23 can also not be provided, etc.

[0031] The base 10 is composed of a grid-like strengthening structure. In this specific embodiment, the grid-like strengthening structure is a "well"-shaped structure 11 formed by the staggered connection of longitudinal beams extending in the length direction and cross beams extending in the width direction. In this way, it can ensure the support strength of the base 10, and at the same time reduce the weight and save transportation and material costs.

[0032] The column of the overhead gantry machine tool forms a bowl-shaped cavity for splicing on the two outer side surfaces in the length direction (i.e., the outer side surface jointly formed by the base 10, the outer support columns 201 and the support beam 30), which can be used for splicing multiple columns of the overhead gantry machine tool to achieve a preset length dimension.

[0033] The support columns 20 are provided with first reinforcing ribs 1 on both sides in the length direction, and the base 10 and the support beams 30 are also provided with first reinforcing ribs 1 on both sides in the length direction. Specifically, the first reinforcing ribs 1 are distributed in a "well" shape and a "rice" shape, and there are hollow holes 4 with hollow treatment between the first reinforcing ribs 1. Similarly, the weight is reduced while ensuring the overall support strength.

[0034] For the preferred structure of the support beam 30, the cross-section of the support beam 30 is a "concave" shape structure, and both sides in the width direction bulge upward to form rails 31 (i.e., linear rails) to enhance the support strength on both sides. A second reinforcing rib 2 is formed between the bottom of the support beam 30 and the connected support column 20, which plays a role in further strengthening the support beam 30.

[0035] In this embodiment, the support beam 30 is provided with a third reinforcing rib 3 conforming to the Pratt truss structure along its length direction, which is used to strengthen the upward load-bearing capacity of the support beam 30 to prevent the support beam 30 from deforming and collapsing at the part without connection to the support column 20 (i.e., the suspended part).

[0036] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them are within the protection scope of the present invention.
