Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC lathes, and in particular to a lathe bed structure. Background Technology
[0002] The lathe bed is a crucial component of a horizontal CNC lathe. During machining, to prevent the lathe turret and workpiece from overheating and ensure machining accuracy, an oil cooling system is necessary. Furthermore, the cutting and milling processes generated by the lathe turret produce a large amount of chips, requiring a chip conveyor for collection and processing. Currently, however, the lathe bed is fully enclosed, with chip removal ports and grooves. Chips enter the bed through the ports and are collected by a collection box or chip conveyor via the connected grooves. This structure, with chip removal ports and grooves on the bed itself, not only increases the bed's weight but also makes casting difficult, hinders chip removal, and leads to chip accumulation. Currently, there is no better solution. Summary of the Invention

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: it includes a bed body, a tailstock guide rail is provided on the bed body, the bed body is L-shaped, the tailstock guide rail is located on the long side of the bed body, the long side and the short side of the bed body form an accommodating cavity, a through groove is opened at the lower part of the long side of the bed body, a side chip removal device is provided on the front side of the bed body or a rear chip removal device is provided on the rear side, the side chip removal device is located at the accommodating cavity, and the rear chip removal device is located at the accommodating cavity and the through groove.
[0005] The side chip removal device includes a side-mounted water tank, a side-mounted water pump, and a side-mounted chip remover. The side-mounted water tank is located in the accommodating cavity, and the side-mounted water pump and the side-mounted chip remover are located on the side of the side-mounted water tank.
[0006] The rear chip removal device includes a front chip removal box, a rear water tank, a rear water pump, and a rear chip conveyor. The front chip removal box is located in the receiving cavity, and the rear water tank is located in the through groove at the bottom of the bed body. Its front end extends into the lower part of the front chip removal box, and its rear end extends out of the rear side of the bed body. The rear water pump and the rear chip conveyor are located on the rear side of the rear water tank.
[0007] The aforementioned front-mounted chip removal box includes a box body, a left water guide plate, and a right water guide plate. The left and right water guide plates are respectively located on the top left and right sides of the box body. A water guide channel is located between the left and right water guide plates, and a rear water tank is located below the water guide channel.
[0008] The left water guide plate is inclined downwards from left to right, and the right water guide plate is inclined downwards from right to left.
[0009] Compared with the prior art, the lathe bed structure of this utility model has the following outstanding advantages: the bed body is L-shaped as a whole, and there are no chip removal ports or chip removal grooves on the bed body, which not only reduces weight but also facilitates casting; the chip removal space is reasonably designed, and the iron chips and cutting fluid on the bed body are directly discharged downward and fall into the chip removal device, which ensures smooth chip removal and prevents chip accumulation.

[0020] Refer to the instruction manual appendix Figure 1 To be continued Figure 9 The following is a detailed description of a lathe bed structure according to the present invention.
[0021] This utility model discloses a lathe bed structure, which includes a bed body 1, on which a tailstock guide rail 11 is provided. The bed body 1 is L-shaped, and the tailstock guide rail 11 is located on the long side 101 of the bed body. The long side 101 and the short side 102 of the bed body 1 form a receiving cavity 12. A through groove 13 is opened at the lower part of the long side 101 of the bed body 1. A side chip removal device 2 is provided on the front side of the bed body 1 or a rear chip removal device 3 is provided on the rear side. The side chip removal device 2 is located at the receiving cavity 12, and the rear chip removal device 3 is located at the receiving cavity 12 and the through groove 13.
[0022] The side chip removal device 2 includes a side-mounted water tank 21, a side-mounted water pump 22, and a side-mounted chip conveyor 23. The side-mounted water tank 21 is located in the accommodating cavity 12, and the side-mounted water pump 22 and the side-mounted chip conveyor 23 are arranged on the side of the side-mounted water tank 21, forming a side chip removal layout for the machine tool.
[0023] The rear chip removal device 3 includes a front chip removal box 31, a rear water tank 32, a rear water pump 33, and a rear chip conveyor 34. The front chip removal box 31 is located in the receiving cavity 12. The rear water tank 32 is located in the through groove 13 at the lower part of the machine bed 1, with its front end extending into the lower part of the front chip removal box 31 and its rear end extending out of the rear side of the machine bed 1. The rear water pump 33 and the rear chip conveyor 34 are located on the rear side of the rear water tank 32, forming a rear chip removal layout for the machine tool.
[0024] The front chip removal box 31 includes a box body 311, a left water guide plate 312, and a right water guide plate 313. The left water guide plate 312 and the right water guide plate 313 are respectively arranged on the top left and right sides of the box body 311. A water guide groove 314 is formed between the left water guide plate 312 and the right water guide plate 313. The left water guide plate 312 is inclined downward from left to right, and the right water guide plate 313 is inclined downward from right to left. This facilitates the entry of iron filings and cutting fluid into the water guide groove 314. The lower part of the water guide groove 314 is the rear water tank 32.
