Common footing structures include Figure 1 As shown, it includes an anchor block 01, and an anchor bolt 02 equipped with an anchor nut 03 is provided on the upper part of the anchor block 01. When the anchor is installed on the machine tool, it is necessary to excavate an anchor support hole on the end face of the machine tool. The anchor block 01 is located at the bottom of the machine tool, and the anchor bolt 02 is inserted upward into the anchor support hole. The anchor nut 03 is located in the anchor support hole. The anchor nut 03 is tightened so that the top surface of the anchor block 01 contacts the bottom end of the machine tool to achieve the installation of the anchor on the machine tool. The height of the top surface of the anchor block 01 is adjustable, and the horizontality of the machine tool can be adjusted by adjusting the height of the top surface of the anchor block 01. Before adjusting the height of the top surface of the anchor block 01, it is necessary to use a wrench to insert into the anchor support hole and loosen the anchor nut 03.

[0003] The horizontal cross-sections of existing anchor support holes are mostly triangular, semicircular or rectangular, and the area of ​​the horizontal cross-section is consistent along the height direction. Although such a structure with the same thickness from top to bottom can ensure the movable space of the wrench, there is a problem of insufficient support rigidity. Utility Model Content

[0004] In order to solve the problem of insufficient supporting rigidity of the existing supporting hole structure, the utility model proposes a ground support hole.

[0005] A foundation support hole comprises an operating hole extending inwardly along an excavation end surface, wherein a through hole penetrating downward is provided on the bottom end surface of the operating hole, and the horizontal cross-sectional area of ​​the operating hole gradually decreases from top to bottom.

[0017] A machine tool comprises a machine tool body, wherein the machine tool body is provided with anchor support holes.

[0018] The beneficial effects of the utility model are:

[0019] (1) In the present invention, the upper space of the working hole is large, which can provide sufficient space for the movement of the wrench; when the upper part of the working hole bears weight, its structure of thicker top and thinner bottom is different from the existing hole structure with the same thickness at the top and bottom, so that a rigid triangular support area surrounded by a circle is formed between the side surface of the working hole and the vertical surface of the top surface, thereby enhancing the support rigidity and support stability for the machine tool, and the displacement generated after bearing the weight of the machine tool is smaller.

[0020] (2) In the present invention, a smooth transition is made between the second side and the third side through the first side having a conical structure.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] like Figure 2-Figure 5As shown, a foundation support hole includes a working hole 1 extending inward along the excavation end surface, and a through hole 2 extending downward is provided on the bottom end surface of the working hole 1, and the horizontal cross-sectional area of ​​the working hole 1 gradually decreases from top to bottom. In the present application, the upper space of the working hole 1 is large, which can provide sufficient space for the movement of the wrench; when the upper part of the working hole 1 bears weight, its structure of being thick at the top and thin at the bottom is different from the existing hole structure with the same thickness at the top and bottom, so that a rigid triangular support area is formed between the side of the working hole 1, the vertical surface 4 of the top surface of the working hole 1, and the extended surface 5 of the bottom end surface of the working hole 1, thereby enhancing the support rigidity and the support stability for the machine tool, and the displacement generated after bearing the weight of the machine tool is small. Among them, the vertical surface 4 of the top end surface of the working hole 1 refers to a vertical surface that is perpendicular to the top end surface of the working hole 1 and extends along the circumference direction of the top end surface, and the extended surface 5 of the bottom end surface of the working hole 1 refers to a surface extending outward from the bottom end surface of the working hole 1 in the horizontal direction.

[0035] Preferably, the working hole 1 includes three side surfaces, a first side surface 11 is opposite to the excavation end surface, and a second side surface 12 is opposite to the third side surface 13;

[0036] The first side surface 11 is a frustum structure, and the radius of the circle where the upper base of the first side surface 11 is located is greater than the radius of the circle where the lower base of the first side surface 11 is located; the central axis of the complete frustum where the first side surface 11 is located is parallel to the central axis of the through hole 2;

[0037] The second side surface 12 and the third side surface 13 are inclined plane structures.

[0038] In the present application, a smooth transition is made between the second side 12 and the third side 13 through the first side 11 having a frustum structure. On the basis of satisfying the space for the wrench to move, the frustum structure of the first side 11 is a flatter structure, which can reduce the internal volume of the anchor support hole and thereby improve the support rigidity.

[0039] Preferably, the second side surface 12 and the third side surface 13 are symmetrical with respect to a radial bisector plane of the first side surface 11 .

[0040] The symmetrical structure of the second side surface 12 and the third side surface 13 can ensure the consistency of the support stiffness at the two side surfaces and ensure the stability of the support for the machine tool.

[0041] Preferably, the second side surface 12 and the third side surface 13 are parallel to the intersection line of the same horizontal plane.

[0042] Preferably, the top end surface and the bottom end surface of the working hole 1 are parallel planar structures, and the central axis of the through hole 2 is perpendicular to the top end surface and the bottom end surface of the working hole 1.

[0043] Preferably, the first side surface 11, the second side surface 12, the third side surface 13 and the top surface of the working hole 1 are smoothly transitioned by rounded corners;

[0044] The first side surface 11 , the second side surface 12 , the third side surface 13 and the bottom end surface of the working hole 1 are smoothly transitioned by chamfering.

[0045] Preferably, the central axis of the through hole 2 lies on the radial bisector of the first side surface 11, thereby ensuring a symmetrical structure for the entire anchor support hole and, in turn, ensuring support stability. The distance between the central axis of the through hole 2 and the excavation end face only needs to be sufficient to facilitate the wrench's deep adjustment of the anchor nut 03, and can be determined based on actual site conditions.

[0046] Preferably, a back countersink 3 is provided on the bottom end surface of the working hole 1 , and the back countersink 3 is coaxially arranged with the through hole 2 .

[0047] Example 2:

[0048] A machine tool comprises a machine tool body, wherein the machine tool body is provided with the anchor support holes in Example 1.

[0049] When installing the anchors in the anchor support holes in this application, if Figure 6 As shown, insert anchor bolt 02 upward into through-hole 2. Screw anchor nut 03 onto the top of anchor bolt 02 through the excavated end face. Use a wrench to tighten anchor nut 03 until it is firmly seated in countersunk hole 3. At this point, the top surface of anchor block 01 contacts the bottom of the machine tool, completing the installation of the anchor on the machine tool. To level the machine tool by adjusting the height of the top surface of the corresponding anchor block 01, first insert a wrench into working hole 1 to loosen the corresponding anchor nut 03. Then, adjust the height of the top surface of anchor block 01 to adjust the machine tool's level. Once the machine tool is level, tighten anchor nut 03 again with a wrench. Additionally, spherical washers can be used when installing anchor nut 03. The structure of the height-adjustable anchor block 01 and the method of adjusting the height of the top surface of the anchor block 01 are both existing technologies. For example, the anchor block 01 includes a supporting base plate 011, and an adjusting screw 012 is rotatably engaged on the supporting base plate 011. The thread on the adjusting screw 012 is engaged with the lower wedge block 013, and the lower wedge block 013 is slidably engaged with the supporting base plate 011. The top surface of the lower wedge block 013 is inclined, and an upper wedge block 014 is slidably engaged on the top inclined surface of the lower wedge block 013. The top surface of the upper wedge block 014 is in contact with the bottom end of the machine tool; when adjusting, the adjusting screw 012 is rotated to move the lower wedge block 013. When the lower wedge block 013 moves, it will cause the top surface of the upper wedge block 014 to rise and fall, thereby adjusting the horizontality of the machine tool.

[0050] In the present application, the upper space of the working hole 1 is large, which can provide sufficient space for the movement of the wrench; when the upper part of the working hole 1 bears weight, its structure of being thicker at the top and thinner at the bottom is different from the existing hole structure with the same thickness at the top and bottom, so that a rigid triangular support area is formed between the side surface of the working hole 1 and the vertical surface of the top surface, thereby enhancing the support rigidity and support stability for the machine tool, and the displacement generated after bearing the weight of the machine tool is smaller.

[0051] Although the above describes the specific implementation methods of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention. Those skilled in the art should understand that on the basis of the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
