Fig. 1 shows a schematic flow chart of a method for manufacturing a machine bed according to an embodiment of the present application.
In some embodiments, referring to fig. 1, embodiments of the present application provide a method of manufacturing a machine tool bed, the method comprising the steps of:
s101, cutting the H-shaped steel to obtain a lathe bed framework; the lathe bed skeleton includes the web and connects two pterygoid laminas in the web both sides, and the web encloses with two pterygoid laminas and closes two holding tanks of separating each other.
Specifically, the H-shaped steel is an economic section efficient section with more optimized section area distribution and more reasonable strength-to-weight ratio, and is named because the section is the same as the English letter 'H'. Because each part of the H-shaped steel is arranged at a right angle, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving, light structure weight and the like in each direction. Therefore, the bed framework made of the H-shaped steel is beneficial to simplifying the manufacturing process of the bed of the machine tool. Optionally, the dimension specification of the H-shaped steel can be 300mm multiplied by 300 mm.
S102, fixing a plurality of reinforcing plates in two accommodating grooves by adopting a first welding process; a plurality of reinforcing plates in each holding tank are arranged at intervals along the longitudinal direction of the lathe bed framework.
Fig. 2 shows a schematic structural diagram of a machine bed in an embodiment of the present application; fig. 3 shows a schematic view of a part of the structure of the machine bed shown in fig. 2.
To explain the structure of the machine bed, referring to fig. 2 and 3, the machine bed 100 includes a bed frame 10 and a plurality of reinforcing plates 20. The bed frame 10 comprises a web 11 and two wing plates 12 connected to two sides of the web 11, and the web 11 and the two wing plates 12 enclose to form two receiving grooves 10a separated from each other. The reinforcing plates 20 are respectively located in the two accommodating grooves 10a, and the reinforcing plates 20 in each accommodating groove 10a are arranged at intervals along the longitudinal direction of the bed frame 10. In this way, the reinforcing plate 20 supports the joint between the web 11 and the wing plate 12, and contributes to an increase in the torsional strength of the machine tool bed 100. The distance between adjacent reinforcing plates 20 is set according to actual needs, and the torsional strength of the machine tool body 100 can be guaranteed to meet the use requirements. Optionally, the bed frame 10 and the reinforcing plate 20 are made of the same or similar materials to ensure welding effect.
In the present embodiment, in the step of fixing the reinforcing plate in the two accommodation grooves by the first soldering process, the solder forms a continuous bead in the soldering direction at the position to be soldered by the first soldering process. With continued reference to fig. 2 and 3, the joints to be welded include the joints between the inner side edges of the reinforcing plate 20 and the web 11 and the joints between the upper and lower side edges of the reinforcing plate 20 and the two wing plates 12, so that the connection strength between the reinforcing plate 20 and the bed frame 10 can be ensured, and the torsional strength and the overall rigidity of the machine bed 100 can be improved.
Optionally, the first welding process can adopt carbon dioxide arc welding, and on one hand, the carbon dioxide arc welding has high crack resistance of a welding line and small deformation after welding, and is beneficial to improving the integral rigidity of the machine tool body. On the other hand, the carbon dioxide gas shielded welding has low welding cost, high production efficiency and simple and convenient operation.
S103, aligning the two side plates with the reinforcing plates to match the positions of the reinforcing plates in each accommodating groove with the positions of the first type holes in the adjacent side plates; the first type holes are arranged at intervals along the longitudinal direction of the side plate.
Referring to fig. 2 and 3, the machine bed 100 further includes two side plates 30, the two side plates 30 are respectively located on two sides of the web 11, and each side plate 30 is respectively connected to the two wing plates 12. The side plate 30 is provided with a plurality of first type holes 30a at intervals along the longitudinal direction, and the first type holes 30a on the side plate 30 correspond to the reinforcing plates 20 in the accommodating grooves 10a corresponding to the side plate 30 in the same number and in the corresponding position relationship.
Specifically, the matching of the positions of the plurality of reinforcing plates in each accommodating groove and the plurality of first type holes on the adjacent side plates structurally shows that any one of the first type holes 30a and the orthographic projection of the reinforcing plate 20 corresponding to the position of the first type hole 30a on the surface of the web 11 at least partially overlap, so that the side plates 30 and the reinforcing plate 20 can be fixed together at one side far away from the web by means of clamping, welding and the like through the first type holes 30 a. Optionally, the first type of hole 30a is configured as a rectangular hole.
And S104, fixing one side of the reinforcing plate, which is far away from the web plate, and the side plate together by virtue of the first type hole.
It can be understood that when the reinforcing plate is fixed in two holding tanks, the inboard edge and the upper and lower both sides limit of reinforcing plate can pass through welded mode with web and two pterygoid laminas respectively and fix together. On the basis of the above, the side of the reinforcing plate far away from the web (i.e. the outer side edge of the reinforcing plate) is fixed with the side plate by means of the first type of hole. Therefore, the circumferential sides of the reinforcing plates can be effectively fixed, and the torsional strength and the overall rigidity of the machine tool body can be improved.
Therefore, in the manufacturing method of the machine tool body, the bed framework is manufactured by cutting the H-shaped steel, which is beneficial to simplifying the manufacturing process of the machine tool body. Set up a plurality of reinforcing plates along the lengthwise direction interval of lathe bed skeleton in the holding tank of lathe bed skeleton, the reinforcing plate plays the supporting role to the junction of web and pterygoid lamina to improve the torsional strength of lathe bed. The side plates are provided with first type holes corresponding to the reinforcing plates, the side plates and the reinforcing plates are fixed together by means of the first type holes, so that the peripheral sides of the reinforcing plates are effectively fixed, the torsional strength of the machine tool body is further improved, and the integral rigidity of the machine tool body is improved.

Therefore, the connection strength of the reinforcing plate 20 and the side plate 30 is fully ensured in a clamping and welding combined mode, and the torsional strength and the overall rigidity of the machine tool body 100 are improved.
In the embodiment shown in fig. 4, when the reinforcing plate 20 is engaged with the first-type hole 30a, the protrusion 21 at least partially protrudes out of the first-type hole 30 a. The boss 21 of the reinforcing plate 20 and the outer side surface of the side plate 30 are fixed together by welding. In the embodiment shown in fig. 5, when the reinforcing plate 20 is engaged with the first-type hole 30a, the protrusion 21 is located in the first-type hole 30 a. Solder is filled into the first-type hole 30a to fix the boss 21 and the inner wall of the first-type hole 30a together by soldering.

In some embodiments, referring to fig. 6, the stiffener 20 is positioned between the side plate 30 and the web 11, and the stiffener 20 is in no snap-fit relationship with the side plate 30. With the aid of the first type of hole, the side of the reinforcing plate away from the web is fixed together with the side plate and specifically includes: the first-type hole 30a is filled with solder to fix the side of the reinforcing plate 20 away from the web 11 and the inner wall of the first-type hole 30a by welding.
