Description
Technical Field
[0001] This invention relates to the field of machine tool technology, and specifically to a modular, splicing machine tool casting and its assembly method. Background Technology
[0002] Machine tool castings are the fundamental load-bearing components of machine tool equipment, bearing the load support and vibration damping functions during machine tool operation. The assembly efficiency and assembly firmness of castings directly affect the assembly period and operational stability of the entire machine tool. Currently, most modular machine tool castings on the market rely on a large number of external fasteners such as screws and high-strength bolts to complete the splicing and fixing between the various casting modules. In actual assembly operations, operators need to align the threaded holes one by one and repeatedly tighten multiple sets of fasteners. This not only makes the assembly operation complex and cumbersome, significantly increasing on-site assembly time and reducing the overall assembly efficiency of the machine tool, but also makes the threaded holes prone to stripping and fastener loosening under repeated disassembly and assembly and long-term machine tool vibration conditions. This will cause the gaps between castings to widen, the rigidity of the entire machine to decrease, affecting the machining accuracy of the machine tool, and also increasing the difficulty of later inspection and maintenance.
[0003] Therefore, it is necessary to invent a modular splicing machine tool casting and its assembly method to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a modular, splicing machine tool casting and its assembly method to solve the problems in the above-mentioned technology.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular splicing machine tool casting, comprising a column support assembly, an end fence assembly, a side fence assembly, a top crossbeam assembly, and a bolt fastening assembly. Four column support assemblies are provided, arranged in a rectangular pattern at the four corners. Two end fence assemblies are provided, symmetrically distributed front to back. Two side fence assemblies are provided, symmetrically distributed left to right. Two top crossbeam assemblies are provided, each positioned directly above one of the two side fence assemblies. Four bolt fastening assemblies are provided, each corresponding to one of the four column support assemblies. The column support assembly, end fence assembly, side fence assembly, and top crossbeam assembly are assembled into a modular structure and secured by the bolt fastening assemblies.
[0006] Preferably, the column support assembly includes a base and a support column. The top of the base has a slot, the bottom of the support column is inserted into the slot, the bottom of the slot has a screw hole, and the middle of the support column has a through hole from top to bottom.
[0007] Preferably, the supporting column has two vertically arranged end splicing slots on the side facing the end fence assembly.

Both ends of the horizontal beams are fixedly connected to end inserts, and the end inserts engage with the end splicing slots at the corresponding positions.
[0008] Preferably, each of the two No. 1 crossbeams has a No. 1 slot on its opposite surface, the number of which is equal to the number of No. 1 connecting posts. The top and bottom ends of each No. 1 connecting post are fixedly connected to a No. 1 locking block. The No. 1 connecting post is locked and fixed to the No. 1 slots of the two No. 1 crossbeams one by one through the No. 1 locking blocks at the top and bottom ends.
[0009] Preferably, the supporting column has two vertically arranged side splicing slots on the side facing the side fence assembly. The side fence assembly includes two horizontal beams arranged vertically and horizontally, and multiple connecting columns arranged in a straight line array. Both ends of the horizontal beams are fixedly connected to side inserts, and the side inserts engage with the corresponding side splicing slots.
[0010] Preferably, the two second crossbeams each have a number of second slots equal to the number of second connecting columns on their opposite surfaces. The top and bottom ends of each second connecting column are fixedly connected with second blocks. The second connecting column is fixedly engaged with the second slots of the two second crossbeams one by one through the second blocks at the top and bottom ends.
[0011] Preferably, the top crossbeam assembly includes a third crossbeam, both ends of which are fixedly connected to a mounting device, which is sleeved with the top of the supporting column.
[0012] Preferably, the end insert has a second through hole in the middle, the side insert has a third through hole in the middle, and the assembly has a fourth through hole in the middle. The central axes of the first, second, third, and fourth through holes and the screw hole coincide with each other, forming a coaxial locking channel.
[0013] Preferably, the bolt fastening assembly includes a long bolt, which passes through four through holes, one through hole, two through holes and three through holes from top to bottom, and its bottom end is threadedly locked to the screw hole of the base. The top of the long bolt is equipped with a handwheel, which can be used to directly rotate the long bolt to achieve quick disassembly and locking operations.
[0014] On the other hand, this application also provides an assembly method for a modular, interlocking machine tool casting, applied to the aforementioned modular, interlocking machine tool casting, comprising the following steps: S1. Assembly and positioning of column support components: Insert the support columns into the slots of the base to complete the assembly of the column support components. Then, place the four column support components evenly according to the four corner points of the rectangle to complete the basic support positioning. S2. Assembly of end fence components: First, connect multiple No. 1 connecting posts to the No. 1 slots of two No. 1 crossbeams through the No. 1 clips at both ends to form end fence components.

Finally, the long bolts are tightened by handwheel, so that the long bolts are threadedly connected to the screw holes of the base, thus completing the integrated locking and fixing of all splicing structures of the whole machine.
[0015] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. All components of the present invention are pre-installed and positioned by means of slots and plugs. The whole machine only needs four long bolts with handwheels to lock all modules at the same time, eliminating the complicated process of aligning and tightening a large number of scattered fasteners of traditional split castings one by one. The assembly and disassembly operations are convenient and efficient, significantly reducing the on-site assembly time of machine tool castings and effectively improving the overall assembly production efficiency. 2. The overall structure adopts a fully modular split casting structure, with each component being independently disassembled. The size and weight of each casting are smaller, which facilitates casting, annealing, transportation and transfer, reduces the risk of defects in the casting of large parts, and lowers warehousing and logistics costs.

S5. Overall structure locking and fixing: The long rod bolts 28 of the bolt fastening assembly 5 are sequentially passed through the coaxial through holes from top to bottom. Finally, the long rod bolts 28 are tightened by the handwheel 29, so that the long rod bolts 28 are threadedly connected to the screw holes 9 of the base 6, thus completing the integrated locking and fixing of all splicing structures of the whole machine.
[0026] Working principle of this invention: Refer to the instruction manual appendix Figure 1-8 When using this invention, firstly, the pre-installation and rectangular corner positioning of the four column support components 1 are completed; the column support component 1 consists of a base 6 and a support column 7. The bottom end of the support column 7 is inserted into the slot 8 opened at the top of the base 6. The bottom of the slot 8 is provided with a screw hole 9. A through hole 10 is opened in the middle of the support column 7. After insertion, an independent column unit is formed. Then, the four sets of column support components 1 are placed at the rectangular corner points to build the basic support frame of the whole machine.
[0027] Subsequently, the end fence assembly is assembled; the end fence assembly 2 includes two No. 1 crossbeams 12 and multiple No. 1 connecting posts 13. The multiple No. 1 connecting posts 13 are arranged in an orderly manner between the two No. 1 crossbeams 12 to assemble a complete end fence; then, the end inserts 14 at both ends of the No. 1 crossbeams 12 are inserted into the end splicing grooves 11 on the supporting posts 7 to complete the symmetrical pre-fixing of the two sets of end fence assemblies 2; a No. 2 through hole 25 is opened in the center of the end insert 14.
[0028] Next, assemble the end fence assembly 2 and the side fence assembly 3. The side fence assembly 3 includes two No. 2 crossbeams 18 and multiple No. 2 connecting posts 19. The multiple No. 2 connecting posts 19 are arranged in an orderly manner between the two No. 2 crossbeams 18 to assemble a complete side fence. Then, the side inserts 20 at both ends of the No. 2 crossbeams 18 are inserted into the side splicing grooves 17 on the supporting posts 7 to complete the symmetrical pre-fixing of the left and right sides of the two sets of side fence assemblies 3. A No. 3 through hole 26 is opened in the center of the side insert 20.
[0029] After assembling the four-sided fence, install two sets of top crossbeam assemblies 4. The main body of the top crossbeam assembly 4 is the No. 3 crossbeam 23, with mounting brackets 24 fixed at both ends. The mounting brackets 24 are then fitted onto the tops of the four supporting columns 7 from top to bottom, completing the alignment of the top structure. A No. 4 through hole 27 is opened in the center of the mounting bracket 24. At this point, the central axes of the No. 4 through hole 27, the No. 1 through hole 10, the No. 2 through hole 25, the No. 3 through hole 26, and the screw hole 9 are completely aligned, forming a coaxial locking channel.
[0030] Finally, four sets of bolt fastening components 5 are used to complete the integrated locking of the whole machine. The bolt fastening components 5 include long bolts 28 and handwheels 29 installed on the top of the bolts. The long bolts 28 are inserted vertically from above the assembly 24 and pass through the fourth through hole 27, the first through hole 10, the second through hole 25, and the third through hole 26 in sequence. Then, the operator turns the handwheel 29 to drive the long bolts 28 to rotate, so that the bottom end of the long bolts 28 is threadedly connected to the screw hole 9 inside the base 6, thus completing the integrated locking and fixing of all the splicing structures of the whole machine.
[0031] During disassembly and maintenance, rotate the handwheel 29 in the opposite direction to unscrew the long rod bolt 28, releasing the locking constraint. Then, the top crossbeam assembly 4, the side fence assembly 3, and the end fence assembly 2 can be removed in sequence. Finally, the column support assembly 1 can be disassembled to achieve rapid separation, transportation, and maintenance of the entire module.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
