Description

Technical Field

[0001] The present invention relates to the technical field of spliced ​​bed structures, in particular to a spliced ​​static pressure bed structure 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 static pressure formed by oil or liquid media controls key moving parts (such as tool holders, guide rails, and spindles) to eliminate mechanical friction and improve stability. The integral cast bed is heavy, with high transportation and installation costs and poor site adaptability. Existing hydrostatic lathe beds mostly adopt a spliced ​​design, combining modular concepts with precision manufacturing requirements. The spliced ​​hydrostatic bed uses modular design, segmented precision control, and dynamic fastening technology to significantly reduce manufacturing costs and improve maintenance efficiency while ensuring high rigidity and stability, making it an ideal solution for long-stroke, high-precision hydrostatic machine tools.

[0051] The present invention is divided into the following steps when used:

[0052] S1: When two lathe bed bodies 11 need to be spliced, the three support columns 13 are placed in appropriate positions. First, the first lathe bed body 11 is placed on the upper left of the middle support plate 12, and the first lathe bed body 11 is placed downward. At this time, the first connecting block 14 will be sleeved on the surface of the positioning plate 16 through the slot 15, and then the lathe bed body 11 will be pushed toward the left support plate 12. The positioning plate 16 will slide inside the rectangular groove of the slot 15 to the inside of the T-slot until it moves to a suitable position, thereby achieving the preliminary positioning of the lathe bed body 11. At this time, the first plug 17 of the first lathe bed body 11 will be inserted into the leftmost positioning block. The second lathe bed body 11 is placed inside the positioning plate 16, and then the second lathe bed body 11 is placed above and slightly to the right of the middle support plate 12. When the second lathe bed body 11 is placed downward, the first connecting block 14 of the second lathe bed body 11 will be sleeved on the surface of the positioning plate 16 on the far right. Then the second lathe bed body 11 is pushed toward the direction of the first lathe bed body 11, and the positioning plate 16 will slide inside the slot 15 until the first plug block 17 is inserted into the inside of the slot 15 and passes through the center positioning plate 16, thereby realizing the splicing of the two lathe bed bodies 11. Through the concave and convex mortise and tenon structure, the two lathe bed bodies 11 are avoided from being misaligned with each other during splicing.

[0053] When the support frame 24 is sleeved on the surface of the connecting plate 22, the positioning rod 210 will slide downward in the receiving hole 28 due to gravity until it is inserted into the positioning hole 29, thereby locking the connecting rod 23. Not only does the support frame 24 and the connecting plate 22 strengthen the support of the lathe bed body 11, preventing the lathe bed body 11 from collapsing during use, but the first protective plate 25 can also be inserted into the first slide groove and slide. When the lathe bed body 11 is used to process objects, the first protective plate 25 is used to block and prevent debris and water droplets from splashing.

[0054] S3: When installing the lathe bed body 11, it should be installed from left to right. When installing the first lathe bed body 11, the first edge banding rod 211 should be installed first. First, the first edge banding rod 211 is covered on the surface of the positioning block 26 through the card slot. At this time, the positioning block 26 is located inside the rectangular groove of the card slot. At the same time, the second connecting block 213 will cover the surface of the left positioning plate 16. Then push the first edge banding rod 211 to the left side, and the positioning block 26 will slide into the inside of the dovetail groove to achieve the positioning of the first edge banding rod 211. Then place the lathe bed body 11 and insert the first plug block 17 into the inside of the second connecting block 213, which is to achieve the connection with the first edge banding rod 21 1, and then insert the second protective plate 212 into the interior of the second slide groove to realize the edge protection of the left lathe bed body 11. When the connection of the lathe bed body 11 is completed, the second edge sealing rod 214 is covered on the surface of the right positioning block 26 through the slot, and then the second edge sealing rod 214 is pushed toward the direction of the lathe bed body 11 to realize the connection between the lathe bed body 11 and the second edge sealing rod 214. Then the third protective plate 215 is inserted into the interior of the third slide groove to realize the edge protection of the right lathe bed body 11. When the overall frame is connected, it can be fixed for the second time by external bolts to realize the limitation of the lathe bed body 11;

[0055] S4: In order to seal the joint, the two lathe bed bodies 11 are connected to each other with a first glue injection groove 31 and a second glue injection groove 32. When spliced, the two will fit together and form a complete pipe. Glue is injected into the inside of the pipe through an external glue injection gun to seal the joint. The first edge sealing rod 211 and the second edge sealing rod 214 are also respectively provided with a third glue injection groove 33 and a fourth glue injection groove 34 at the joints with the lathe bed body 11. Glue can be injected into the inside to connect and fix them to the lathe bed body 11.

[0056] S5: In order to prevent the joint seam from increasing due to the increase in volume of the glue when solidifying during glue injection, the electric push rods 41 are installed on the bottom surface of the appropriate support plate 12 from left to right, so that the output shaft of the electric push rod 41 is extended to a suitable position, and then the extrusion plate 43 is moved upward on the surface of the output shaft until the extrusion plate 43 and the reinforcement rib 21 are in contact with each other. Then, the electric push rod 41 is started to shrink the output shaft, and the extrusion plate 43 is squeezed by the stabilizing plate 42. The extrusion plate 43 applies force to the reinforcement rib 21, so that the joint seam is tighter and will not be deformed during glue injection;

[0057] S6: When pouring glue, glue will spread out from the joints. When the glue solidifies, place the glue scraper block 51 on the upper surface of the lathe bed body 11, then fill oil into the oil filling bottle 52, and then push the glue scraper block 51 to move on the surface of the lathe bed body 11. The glue scraper block 51 will scrape off the overflowing glue, and the oil inside the oil filling bottle 52 will flow to the brush roller 54 through the oil outlet pipe 53. 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, not only the lathe bed body 11 is maintained, but also the glue after the splicing seam solidifies can be sealed, which reduces oxidation and increases the service life of the glue.

[0058] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
