Description

Technical Field

[0001] This application relates to the field of CNC machine tool technology, and more specifically to a machining center column. Background Technology

[0002] The machining center column is a crucial component used to assemble necessary parts such as the spindle box, tool magazine, electrical control box, and motors. A machining center column typically has a vertically extending first cavity, as well as a first sidewall and a second sidewall, which are positioned opposite each other across the first cavity. A slide rail is installed on the outer side of the first sidewall for sliding connection to the spindle box. Therefore, the machining center column must bear the weight of the spindle box, which can easily cause deformation of the machining center column towards the side where the spindle box is located.

[0003] Therefore, how to improve the rigidity of the machining center column to reduce the deformation of the machining center column towards the side where the spindle box is located remains a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, in order to solve the above-mentioned technical problems, this application provides a machining center column, which includes:

[0005] The column body has a first cavity extending vertically; the column body has a first sidewall and a second sidewall disposed opposite to each other across the first cavity; the outer side of the first sidewall is used to install a slide rail;

[0006] And a reinforcing wall, which is disposed in the first cavity and connected to the first side wall and the second side wall respectively, so as to divide the first cavity into a first sub-cavity and a second sub-cavity;

[0007] The reinforcing wall includes ribs and holes. The ribs are connected to the first sidewall and the second sidewall, respectively. The holes are connected to the first sub-cavity and the second sub-cavity, respectively. The holes and ribs are arranged alternately.

[0008] Beneficial effects: Unlike the prior art, in this application, by using alternating holes and ribs, the rigidity of the machining center column can be strengthened by the ribs, avoiding or reducing the deformation of the machining center column towards the side where the spindle box is located, and the increase in the weight of the machining center column can be reduced by the holes, thereby avoiding the machining center column from being too heavy.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figures 1-5 As shown, the machining center column 10 of this application includes a column body 100 and a reinforcing wall 200.

[0021] The column body 100 has a first cavity 11 extending vertically in the direction H. The column body 100 has a first sidewall 101 and a second sidewall 102 disposed opposite to each other across the first cavity 11. The outer side of the first sidewall 101 is used to mount a slide rail (not shown). A reinforcing wall 200 is disposed within the first cavity 11 and connects to the first sidewall 101 and the second sidewall 102, dividing the first cavity 11 into a first sub-cavity 11-1 and a second sub-cavity 11-2. The reinforcing wall 200 includes a rib 210 and a hole 220. The rib 210 connects to the first sidewall 101 and the second sidewall 102. The hole 220 communicates with the first sub-cavity 11-1 and the second sub-cavity 11-2. The hole 220 and the rib 210 are alternately arranged.

[0022] By using the above-described method and alternating holes 220 and ribs 210, the rigidity of the machining center column 10 can be strengthened by the ribs 210, avoiding or reducing the deformation of the machining center column 10 towards the side where the spindle box is located. At the same time, the holes 220 can reduce the increase in the weight of the machining center column 10, thereby preventing the machining center column 10 from becoming too heavy.

[0023] Optionally, such as Figures 1-5 As shown, with the interval direction between the first sidewall 101 and the second sidewall 102 as the longitudinal direction L, the rib portion 210 and the hole portion 220 are alternately arranged along the vertical direction H and / or the longitudinal direction L.

[0024] Optionally, such as Figures 1-5 As shown, the column body 100 includes a base portion 110 and an upper extension portion 120. A protrusion 112 protrudes upward from the top of the base portion 110. The protrusion 112 gradually tapers upward. The bottom end of the upper extension portion 120 connects to the protrusion 112. A first cavity 11 extends to both the upper extension portion 120 and the protrusion 112. The machining center column 10 includes a slide rail mounting portion 130, which is located on the outer side of the first sidewall 101 and extends vertically H to the base portion 110. The slide rail mounting portion 130 is used to mount a slide rail.

[0025] In this manner, the protrusion 112 gradually contracts from bottom to top, enabling the base portion 110 to more stably support the upper extension portion 120.

[0026] Optionally, such as Figures 1-7 As shown, a recess 111 is provided at the bottom end of the base portion 110. The recess 111 connects to the outer side of the first side wall 101 and the outer side of the second side wall 102, so that the side wall of the recess 111 forms a support foot portion 113. A support surface 116 is provided on the bottom surface of the support foot portion 113, which is used to support the machine tool body (not shown).

[0027] The distance from the top of the protrusion 112 to the support surface 116 along the vertical direction H is the first dimension d1. The distance from the top of the protrusion 112 to the top of the machining center column 10 along the vertical direction H is the second dimension d2. The second dimension d2 is smaller than the first dimension d1.

[0028] In this way, the recessed portion 111 can reduce the weight of the machining center column 10. Since the second dimension is smaller than the first dimension d1, the rigidity of the machining center column 10 can be improved. Optionally, the first dimension d1 is 870mm~1070mm, and the second dimension d2 is 620mm~820mm, but is not limited thereto. Optionally, the difference between the first dimension and the second dimension is 200mm~300mm, but is not limited thereto.

[0029] Optionally, such as Figures 1-7 As shown, the dimension of the support surface 116 along the transverse W is the third dimension d3, which is 140mm~180mm. In this way, the support surface 116 can provide more stable support to the machine tool body.

[0030] For example, and not as a limitation, in one example, the first dimension d1 is 970 mm, the second dimension d2 is 720 mm, and the third dimension d3 is 160 mm. In another example, the first dimension d1 is 870 mm, the second dimension d2 is 620 mm, and the third dimension d3 is 140 mm. In yet another example, the first dimension d1 is 1070 mm, the second dimension d2 is 820 mm, and the third dimension d3 is 180 mm.

[0031] Optionally, such as Figures 1-7 As shown, with the direction perpendicular to the longitudinal direction L and the vertical direction H as the transverse direction W, the column body 100 has a third side wall 103 and a fourth side wall 104. The third side wall 103 and the fourth side wall 104 are arranged opposite each other along the transverse direction W, separated by the first cavity 11.

[0032] The upper extension 120 includes a column portion 121, a first side plate portion 122, a second side plate portion 123, and a third side plate portion 124. The bottom end of the column portion 121 is connected to the protrusion 112. The first cavity 11 passes through the top end of the column portion 121 and extends into the protrusion 112.

[0033] The slide rail mounting portion 130 includes an extension post 131, which extends vertically in the direction of H and has its top end protruding from the top end of the column portion 121. At least one extension post 131 is a first extension post 131a, and at least one extension post 131 is a second extension post 131b. A first side plate portion 122 extends upward from the third side wall 103 and connects to the top end of the first extension post 131a, and a second side plate portion 123 extends upward from the fourth side wall 104 and connects to the top end of the second extension post 131b. A third side plate portion 124 extends upward from the first side wall 101 and connects to the top ends of both the first extension post 131a and the second extension post 131b.

[0034] In this manner, while maintaining sufficient rigidity of the portion of the extension column 131 protruding from the top of the column body 121 using the first side plate portion 122, the second side plate portion 123, and the third side plate portion 124, more length for mounting slide rails is provided by the portion of the extension column 131 protruding from the top of the column body 121.

[0035] Optionally, such as Figures 1-7 As shown, the extension column 131 is formed into a cavity structure that communicates with the first cavity 11. This allows the extension column 131 to have sufficient rigidity while also achieving a lightweight design.

[0036] Optionally, such as Figures 1-7 As shown, a slide rail mounting surface 132 is formed on the side of the extension column 131 opposite to the column body 121. The slide rail mounting surface 132 is used to mount the slide rail, and the first extension column 131a and the second extension column 131b are spaced apart along the transverse direction W, but this is not a limitation. In other examples, the extension column 131 may not be provided, in which case the slide rail mounting surface 132 can be directly provided on the outer side of the first side wall 101.

[0037] Optionally, such as Figures 1-7 As shown, the first side plate portion 122 gradually tapers from bottom to top along the longitudinal direction L. The second side plate portion 123 also gradually tapers from bottom to top along the longitudinal direction L. This reduces the production cost of the first side plate portion 122 and the second side plate portion 123 while maintaining sufficient rigidity in the portion of the extension column 131 that protrudes from the top of the column portion 121.

[0038] Optionally, such as Figures 1-7 As shown, multiple reinforcing ribs 140 are provided on the inner surfaces of the first sidewall 101, the second sidewall 102, the third sidewall 103 and the fourth sidewall 104. The multiple reinforcing ribs 140 are interconnected and extend along the inner surfaces of the first sidewall 101, the second sidewall 102, the third sidewall 103 and the fourth sidewall 104.

[0039] By using the above method, the rigidity of the first sidewall 101, the second sidewall 102, the third sidewall 103 and the fourth sidewall 104 can be improved by using multiple interconnected reinforcing ribs 140, thereby improving the rigidity of the machining center column 10.

[0040] Optionally, such as Figures 1-7 As shown, an enclosing area 150 is formed between the reinforcing ribs 140, and the enclosing area 150 and the reinforcing ribs 140 are alternately distributed along the inner surfaces of the first sidewall 101, the second sidewall 102, the third sidewall 103, and the fourth sidewall 104. In this way, the rigidity of the first sidewall 101, the second sidewall 102, the third sidewall 103, and the fourth sidewall 104 can be further improved.

[0041] Optionally, such as Figures 1-7 As shown, the second sidewall 102 is provided with a first through hole 12, which communicates with the first cavity 11. This first through hole 12 enhances the flow of air between the first cavity 11 and the outside environment, thereby improving heat dissipation performance.

[0042] Optionally, such as Figures 1-7 As shown, a second cavity 13 is provided within the protrusion 112, and the second cavity 13 is located on both sides of the first cavity 11 along the transverse direction W. The base is provided with a second through hole 14, which is located on the third side wall 103 and the fourth side wall 104 respectively, and communicates with the second cavity 13. Thus, the second cavity 13 allows for a lighter base portion 110. The second through hole 14 provides ventilation between the second cavity 13 and the outside air, thereby improving heat dissipation performance.

[0043] Optionally, such as Figures 1-7 As shown, the side wall of the support leg 113 is provided with a weight-reducing groove 114, and the side wall of the support surface 116 of the weight-reducing groove 114 is provided with a mounting hole 115, which penetrates the support surface 116. In this way, the weight-reducing groove 114 can achieve weight reduction of the base 110, thereby achieving a lightweight design. Screws can be installed through the mounting hole 115 to fix the machining center column 10 to the machine tool body. It should be noted that the mounting hole 115 can be a threaded hole or a smooth hole, but is not limited to these.

[0044] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
