DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0026] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] In a first aspect, an embodiment of the present application provides a method for manufacturing a machine tool base, comprising: S1, casting various parts of a machine tool base 1 from cast iron raw materials through a mold, and splicing the various parts into a whole of the machine tool base 1 to facilitate transportation and installation of the machine tool base 1; S2, pouring a composite mineral 2 into a receiving groove 12 above the spliced ​​machine tool base 1; utilizing the characteristics of the composite mineral 2 that quickly solidifies and forms an adhesive layer, connecting the components of the machine tool base 1 to improve the stability of the machine tool base 1 and avoid loosening of the bolts of the machine tool base 1 due to vibration of the machine tool during use; in addition, the composite mineral 2 also has High shock absorption can improve the shock absorption effect of the machine tool base 1; at the same time, the mechanical properties of the composite mineral 2 are not as good as those of cast iron materials, that is, the solidified composite mineral 2 casting is easy to break, and affects its application in heavy load or high stress environment. Therefore, the entire machine tool base 1 of the embodiment of the present application is not made of composite minerals 2, because the cost is high if all composite minerals 2 are cast; on the other hand, it is easy to bump during transportation. Therefore, the entire machine tool base 1 is a cast iron part with high structural strength, and the composite mineral 2 is poured in the receiving groove 12, and the cast iron part will protect the composite mineral 2. The manufacturing method of the machine tool base 1 of the embodiment of the present application combines the advantages of cast iron materials and the advantages of composite minerals 2, avoiding their respective disadvantages, so that the manufactured machine tool base 1 has a stable structure, good shock absorption effect, and meets the mechanical properties.

[0028] Optionally, in some cases, the machine tool base 1 may be an integrated structure instead of being composed of multiple sections, and the composite mineral 2 may be poured in the receiving groove 12, so that the manufactured machine tool base has a stable structure, good shock absorption effect, and meets the mechanical properties.

[0029] As an implementation mode, a plurality of protrusions 3 are cast in the receiving groove 12 , and the protrusions 3 are in contact with the composite mineral 2 , thereby increasing the contact area between the composite mineral 2 and the machine tool base 1 , and further improving the stability of the machine tool base 1 .

[0030] As an implementation method, before pouring the composite mineral 2, the assembled machine tool base 1 is placed at an angle. Through the above arrangement, the solidified composite mineral 2 is high at one end and low at the other end. In this way, when the machine tool base 1 is actually used, the top surface of the composite mineral 2 and the machine tool base 1 form a coolant channel 4. The top surface of the composite mineral 2 forms an inclined surface, which facilitates the flow of coolant, thereby taking away the chips formed by cutting and grinding, avoiding oxidation of the retained chips, and mixing them with the chips when the equipment is used again, which will affect the deterioration of the coolant.

[0031] Optionally, the assembled machine tool base 1 can be placed on an inclined platform and then poured with the composite mineral 2; of course, one end of the assembled machine tool base 1 can also be raised.

[0032] Optionally, the composite mineral 2 can achieve self-leveling by its own gravity after pouring; of course, other vibration devices can also be used to accelerate the flow of the composite mineral 2 to shorten the self-leveling time of the composite mineral 2.

[0033] like Figure 1 and 4 As shown, in the second aspect, an embodiment of the present application provides a machine tool base, wherein the machine tool base 1 is a cast iron part, and is composed of multiple sections, so as to facilitate the transportation and installation of the machine tool base 1, wherein a receiving groove 12 is provided above the machine tool base 1, and the receiving groove 12 is filled with a composite mineral 2. The viscosity of the composite mineral 2 is used to connect the components of each machine tool base 1 to improve the stability of the machine tool base 1 and avoid the loosening of the bolts of the machine tool base 1 due to the vibration of the machine tool during use; in addition, the composite mineral 2 also has high shock absorption, which can improve the shock absorption effect of the machine tool base 1; at the same time, the mechanical properties of the composite mineral 2 are not as good as those of cast iron materials, that is, the composite mineral 2 casting after solidification is easy to break, and affects its application in heavy load or high stress environment. Therefore, the whole of the machine tool base 1 of the embodiment of the present application is not entirely made of composite minerals 2, because all composite minerals 2 are cast, on the one hand, the cost is high; on the other hand, it is easy to bump during transportation, so the whole of the machine tool base 1 is a cast iron part with high structural strength, and the composite mineral 2 is cast in the receiving groove 12, and the cast iron part will protect the composite mineral 2. The manufacturing method of the machine tool base 1 of the embodiment of the present application combines the advantages of cast iron materials and composite minerals 2, avoids their respective shortcomings, so that the manufactured machine tool base 1 has a stable structure, good shock absorption effect, and meets the mechanical properties.

[0034] like Figure 1 As shown, optionally, the machine tool base 1 is composed of a plurality of connecting sections 11, and two adjacent connecting sections 11 are fixedly connected. A bolt hole is provided on the side of each connecting section 11, that is, a plurality of bolt holes are provided on the peripheral wall 14 of the machine tool base 1, and two adjacent connecting sections 11 can be fixed by bolts.

[0035] Optionally, the number of connecting segments 11 may be three, two, or more.

[0036] Optionally, in some cases, the machine tool base 1 may be an integrated structure instead of being composed of multiple sections, and the composite mineral 2 may be poured in the receiving groove 12, so that the manufactured machine tool base has a stable structure, good shock absorption effect, and meets the mechanical properties.

[0037] like Figure 3As shown, as an embodiment, at least one wall surface of the receiving groove 12 is provided with a plurality of contact portions for increasing the contact area with the composite mineral 2. The contact area with the composite mineral 2 is increased by the contact portions, thereby improving the stability of the connection between the composite mineral 2 and the machine tool base 1, and further improving the structural stability of the machine tool base 1.

[0038] Optionally, the structure of the contact portion is not limited, and may be a groove-shaped structure or a protruding structure. Meanwhile, the shape of the contact portion is also not limited, and may be a special-shaped structure, that is, an irregular structure, or a regular shape.

[0039] Optionally, the contact portion may be disposed at the bottom or side of the receiving groove 12 , and of course, may also be disposed at both the bottom and the side.

[0040] like Figure 1 As shown, as an embodiment, the connection portion includes a protrusion 3, which is located at the bottom of the receiving groove 12 and can fully contact the composite mineral 2 to improve the stability between the composite mineral 2 and the machine tool base 1; the protrusion 3 includes a first protrusion 31 and a plurality of second protrusions 32, one end of the first protrusion 31 is connected to the plurality of second protrusions 32, and the first protrusion 31 and the plurality of second protrusions 32 are arranged at an angle to each other, so that the protrusion 3 is a "Y"-shaped structure, ensuring that it can contact the composite mineral 2 in all directions, thereby increasing the contact area between the protrusion 3 and the composite mineral 2 and improving the structural strength of the machine tool base 1. Optionally, the length of the first protrusion 31 is greater than the length of the second protrusion 32, thereby extending the length of the first protrusion 31 and increasing the contact area between the protrusion 3 and the composite mineral 2.

[0041] like Figure 1 As shown, optionally, one end of the first protrusion 31 is connected to the side of the receiving groove 12 , which is also the outer peripheral wall 14 of the entire machine tool base 1 .

[0042] Of course, the contact portion may also include a special-shaped groove, which is located at the bottom of the receiving groove 12, that is, the special-shaped groove extends downward along the bottom of the receiving groove 12. When the special-shaped groove is filled with the composite mineral 2, it is equivalent to pouring more composite minerals 2 in the receiving groove 12. When the special-shaped groove can fully contact the composite mineral 2, compared with the structure in which the contact portion is a protrusion 3, it can better improve the stability between the composite mineral 2 and the machine tool base 1; the special-shaped groove includes a first recessed area and multiple second recessed areas, one end of the first recessed area is connected to the multiple second recessed areas, and the first recessed area and the multiple second recessed areas are arranged at an angle to each other, so that the special-shaped groove has a "Y"-shaped structure, ensuring that it can contact the composite mineral 2 in all directions, thereby increasing the contact area between the special-shaped groove and the composite mineral 2 and improving the structural strength of the machine tool base 1.

[0043] Optionally, the length of the first recessed area is greater than the length of the second recessed area, thereby extending the length of the first recessed area and increasing the contact area between the special-shaped groove and the composite mineral 2 .

[0044] Optionally, one end of the first recessed area is connected to the side of the accommodating groove 12 , which is also the outer peripheral wall 14 of the entire machine tool base 1 .

[0045] Optionally, the embodiment of the present application designs the contact part into a "Y"-shaped structure, which also utilizes bionics. The reason why the gecko can fly over eaves and walls is that the pads of the feet and the scales under the toes are densely covered with rows of toe folds, which are composed of clusters of bristles, and the ends of the bristles are forked to form hundreds of smaller shovel-shaped hairs, similar to the "Y" shape. Therefore, the contact part of the embodiment of the present application is designed into a "Y"-shaped structure, which can increase the contact area between the contact part and the composite mineral 2 and improve the structural stability of the machine tool base 1.

[0046] like Figure 1 and 3 As shown, as an embodiment, the machine tool base 1 includes a peripheral wall 14 located on the periphery and a support portion 15 located in the area surrounded by the peripheral wall 14, and the support portion 15 is connected to the peripheral wall 14 through a connecting portion 7. The peripheral wall 14 serves as one part of the side of the receiving groove 12, the support portion 15 serves as another part of the side of the receiving groove 12, and the connecting portion 7 serves as the bottom of the receiving groove 12, so that the receiving groove 12 is protected by cast iron parts all around. In this way, when the composite mineral 2 is poured in the receiving groove 12, the machine tool base 1 can protect the composite mineral 2 and prevent the composite mineral 2 from being exposed to the outside and easily bumped. A groove for accommodating a linear motor is provided on the top of the support portion 15.

[0047] like Figure 3 and 4 As shown, as an embodiment, the support portion 15 includes a vertical section 151 and a horizontal section 152. The horizontal section 152 is connected to the vertical section 151 and extends along the width direction of the machine tool base 1. The horizontal section 152 is in contact with the composite mineral 2, and supports the bottom of the horizontal section 152. In addition, the contact area between the composite mineral 2 and the machine tool base 1 is increased, so that the composite mineral 2 can be completely poured into the receiving groove 12.

[0048] Optionally, the horizontal section 152 may be used to support a guide rail on a machine tool.

[0049] Optional, width direction is attached Figure 2 The Y direction in the figure is the length direction. Figure 2 The X direction in .

[0050] Optionally, two horizontal sections 152 are provided, extending in different directions respectively.

[0051] like Figure 4 and 5 As shown, as an embodiment, the top surface of the composite mineral 2 is lower than the height of the peripheral wall 14, and a coolant channel 4 is formed between the peripheral wall 14 and the horizontal section 152, and the top surface of the composite mineral 2 serves as the bottom surface of the coolant channel 4. In this way, when the machine tool is working, the coolant generated can flow into the coolant channel 4, thereby carrying and guiding the coolant to prevent the coolant from splashing around the machine tool. Secondly, it accelerates the return flow of the coolant and chips and reduces the heat release in the working space of the machine tool.

[0052] like Figure 2 As shown, as an embodiment, a through hole 5 is provided on one side of the peripheral wall 14, and the through hole 5 is located at one end of the length direction of the machine tool base 1; the top surface of the composite mineral 2 is inclined from one end to the other end along the length direction, and the through hole 5 is at the same end as the lowest end of the composite mineral 2, so as to facilitate the flow of coolant, so that the coolant can take away the chips formed by milling and grinding, and flow out from the through hole 5, so as to avoid oxidation of the retained chips. When the equipment is used again, the oxidized chips will be mixed with the coolant, which will accelerate the deterioration of the coolant.

[0053] like Figure 1 As shown, optionally, the machine tool base 1 also includes a protruding grinding head support seat 6, which is used to support the grinding head of the machine tool. The upper end surface of the grinding head support seat 6 is provided with a circle of recessed area, and the recessed area is connected to the receiving groove 12, which can carry and guide the coolant of the grinding head part of the machine tool.

[0054] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
