Description

Technical Field

[0001] The present invention relates to the technical field of spliced bed bodies, and specifically to a spliced hydrostatic bed body based on a mortise and tenon structure. Background Art

[0002] A hydrostatic lathe is a device that uses liquid hydrostatic technology to achieve high-precision machining. The key moving parts (such as the tool rest, guide rail, spindle, etc.) are controlled by the static pressure formed by oil or liquid medium to eliminate mechanical friction and improve stability. The overall cast bed body is heavy, with high transportation and installation costs and poor site adaptability. Most existing hydrostatic lathe bed bodies adopt a spliced design, combining the modular concept with the requirements of precision manufacturing. The spliced hydrostatic bed body, through modular design, segmented precision control, and dynamic fastening technology, while ensuring high rigidity and stability, significantly reduces manufacturing costs and improves maintenance efficiency, becoming an ideal solution for long-stroke and high-precision hydrostatic machine tools.

[0003] In the prior art, there are certain limitations for spliced hydrostatic bed bodies:

[0004] 1. When the existing lathes are spliced, basically two bed bodies are mutually attached and then fastened with bolts. However, when docking, the two bed bodies are not limited, and it is extremely easy to be misaligned, resulting in an uneven bed body and inconvenient use.

[0005] 2. After the existing lathes are spliced, there are still gaps, and liquid will still leak through the splicing seams during use. Summary of the Invention

[0054] The use of the present invention is divided into the following steps:

[0055] S1: When it is necessary to splice two lathe bed bodies 11, place the three support columns 13 at appropriate positions. First, place the first lathe bed body 11 above and to the left of the middle support plate 12, and lower the first lathe bed body 11. At this time, the first connecting block 14 will be sleeved on the surface of the positioning plate 16 through the slot 15. Then, push the lathe bed body 11 towards the left support plate 12. The positioning plate 16 will slide into the T-shaped slot inside the rectangular slot of the slot 15 until it moves to an appropriate position, achieving the preliminary positioning of the lathe bed body 11. At this time, the first insertion block 17 of the first lathe bed body 11 will be inserted into the leftmost positioning plate 16. Then, place the second lathe bed body 11 above and to the right of the middle support plate 12. When lowering the second lathe bed body 11, the first connecting block 14 of the second lathe bed body 11 will be sleeved on the surface of the rightmost positioning plate 16. Then, push the second lathe bed body 11 towards the first lathe bed body 11. The positioning plate 16 will slide inside the slot 15 until the first insertion block 17 is inserted into the slot 15 and penetrates the central positioning plate 16, thus achieving the splicing of the two lathe bed bodies 11. Through the concave-convex mortise and tenon structure, it is possible to avoid the mutual dislocation of the two lathe bed bodies 11 during splicing.

[0056] S2: When it is necessary to install the protection, sleeve the connecting rod 23 on the surface of the positioning block 26 through the limit slot 27. At this time, the positioning block 26 is located inside the rectangular slot of the limit slot 27. Then, apply force to the positioning rod 210 to make the positioning rod 210 slide upward inside the receiving hole 28. Then, push the connecting rod 23 towards the direction close to the lathe bed body 11. The positioning block 26 will slide into the square cone slot until the support frame 24 is sleeved on the surface of the connecting plate 22. Until the support frame 24 moves to an appropriate position, the positioning rod 210 will slide downward inside the receiving hole 28 due to gravity until it is inserted into the positioning hole 29, achieving the locking of the connecting rod 23. Not only does it strengthen the support for the lathe bed body 11 through the support frame 24 and the connecting plate 22 to prevent the lathe bed body 11 from collapsing during use, but also the first protection plate 25 can be inserted into the first sliding groove and slide. When using the lathe bed body 11 to process items, it can be blocked by the first protection plate 25 to prevent debris and water droplets from splashing;

[0057] S3: When installing the main body 11 of the lathe bed, it should be installed from left to right. When installing the first main body 11 of the lathe bed, the first edge-sealing rod 211 should be installed first. First, cover the first edge-sealing rod 211 on the surface of the positioning block 26 through the card slot. At this time, the positioning block 26 is located inside the rectangular slot of the card slot. At the same time, the second connecting block 213 will cover the surface of the left positioning plate 16, and then push the first edge-sealing rod 211 to the left side. The positioning block 26 will slide into the dovetail slot, thus realizing the positioning of the first edge-sealing rod 211. Then place the main body 11 of the lathe bed, insert the first plug 17 into the second connecting block 213, which realizes the connection with the first edge-sealing rod 211. Then insert the second protective plate 212 into the second chute to realize the edge-sealing protection of the left main body 11 of the lathe bed. After the main body 11 of the lathe bed is connected, cover the second edge-sealing rod 214 on the surface of the right positioning block 26 through the card slot, and then push the second edge-sealing rod 214 towards the main body 11 of the lathe bed to realize the connection between the main body 11 of the lathe bed and the second edge-sealing rod 214. Then insert the third protective plate 215 into the third chute to realize the edge-sealing protection of the right main body 11 of the lathe bed. After the overall frame is connected, it can be secondarily fixed through external bolts to realize the limit of the main body 11 of the lathe bed;

[0058] S4: In order to seal the splicing part, the first glue injection groove 31 and the second glue injection groove 32 are respectively opened at the mutual connection parts of the two main bodies 11 of the lathe bed. When they are spliced, they will be mutually attached and form a complete pipeline. Glue is injected into the pipeline through an external glue gun, and the splicing part is sealed through the glue. The third glue injection groove 33 and the fourth glue injection groove 34 are also respectively opened at the mutual attachment parts of the first edge-sealing rod 211 and the second edge-sealing rod 214 and the main body 11 of the lathe bed, and glue can be respectively injected into them to realize the connection and fixation with the main body 11 of the lathe bed;

[0059] S5: In order to prevent the splicing seam from increasing due to the increase in volume during the solidification of the glue during glue injection, the electric push rods 41 are installed on the bottom surface of the appropriate support plates 12 from left to right in sequence, so that the output shafts of the electric push rods 41 extend to appropriate positions. Then move the extrusion plate 43 upward on the output shaft surface until the extrusion plate 43 is mutually attached to the reinforcing rib 21. Then start the electric push rod 41 to make the output shaft contract. The extrusion plate 43 is extruded through the stabilizing plate 42, and the extrusion plate 43 applies force to the reinforcing rib 21, so that the splicing seam is tighter and will not deform during glue filling;

[0060] S6: When pouring glue, the glue will spread out from the splicing joint. After the glue solidifies, place the glue scraping block 51 on the upper surface of the lathe bed body 11, then pour oil into the oil injection bottle 52, and then push the glue scraping block 51 to move on the surface of the lathe bed body 11. The glue scraping block 51 will scrape off the overflowed glue, and the oil in the oil injection bottle 52 will flow through the oil outlet pipe 53 to the brush roller 54. The brush roller 54 will roll on the surface of the lathe bed body 11, and the maintenance oil will be applied to the surface of the lathe bed body 11 through the rolling of the brush roller 54. While removing the glue, it not only maintains the lathe bed body 11, but also seals the glue after solidification at the splicing joint, reduces oxidation, and increases the service life of the glue.
