Abstract
Description
Technical Field
[0001] This invention relates to the field of machining, and in particular to a lathe coolant collection and recovery device. Background Technology
[0002] When machining large shaft components on lathes, manufacturers need to spray coolant onto the turning areas to ensure machining efficiency and tool stability. Part of the coolant sprayed onto the shaft surface falls into the lathe's collection tank under gravity, is filtered, and then recycled. The remaining coolant is thrown off the shaft by centrifugal force.
[0003] Currently, a container is typically installed on one side of the lathe, containing an upward-extending baffle that corresponds to the axial movement range of the cutting tool. Coolant detaching from the shaft impacts the baffle and collects in the container under gravity. However, the container's collection capacity is limited, requiring frequent removal of the baffle to empty the collected coolant. This process necessitates reducing the shaft's rotational speed to minimize the amount of coolant ejected, impacting the shaft's machining progress. Furthermore, it involves significant manual labor, and the emptying process can easily spill coolant, causing pollution to the factory floor next to the lathe.
[0004] Therefore, how to efficiently collect and recycle the coolant ejected from the shaft is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a lathe coolant collection and recovery device. This device has a simple structure, low modification cost, and can effectively recover and utilize the coolant ejected during lathe machining, while ensuring that the recovered coolant meets quality standards.
[0006] The technical solution of the present invention is: a lathe coolant collection and recovery device, comprising a lathe mounting base raised above the factory ground, a dike set on the factory ground on one side of the lathe mounting base, the dike having a gap distance from the lathe mounting base, and the first and last ends of the dike being connected to the two ends of one side of the lathe mounting base, respectively, forming a closed collection area, the collection area being provided with a baffle, an isolation groove, a first collection pit and a second collection pit, the baffle corresponding to the axial movement range of the cutting tool, the isolation groove laterally dividing the collection area, the opening of the first collection pit being flush with the collection area and communicating with the isolation groove, located between the baffle and the second collection pit, the first collection pit being connected to the second collection pit through an overflow port, the second collection pit providing coolant to the outside, and the collection area being covered with a sieve plate to protect the first collection pit and the isolation groove.
[0007] The opening of the second collection pit is higher than the collection area, and the opening of the second collection pit is covered with a cover plate.
[0008] A filter cylinder is provided in the first collection pit, and the shape of the filter cylinder is adapted to the inner cavity shape of the first collection pit.
[0009] The depth of the second collection pit is less than the depth of the first collection pit, and the cross-sectional area of the second collection pit is greater than the cross-sectional area of the first collection pit.
[0010] The height of the cofferdam is the same as the height of the lathe mounting base.
[0011] The inner wall of the cofferdam is inclined, and the outer wall is vertical.
[0012] It also includes a delivery pump, the inlet of which is connected to a second collection pit via a pipeline and is liquid-sealed, and the outlet of the delivery pump supplies coolant to the lathe via a pipeline.
[0013] The overflow outlet of the first collection pit is either an open channel or a culvert.
[0014] The above technical solution has the following beneficial effects: 1. The lathe coolant collection and recovery device includes a lathe mounting base elevated above the factory ground level, used for mounting the lathe. A dike is set on the factory ground on one side of the lathe mounting base, with a gap between the dike and the lathe mounting base. The dike's first and last ends are connected to the two ends of one side of the lathe mounting base, forming a closed collection area, i.e., the dike closes with one side of the lathe mounting base. This collection area includes a baffle, an isolation trough, a first collection pit, and a second collection pit. The baffle corresponds to the axial movement range of the cutting tool. The coolant spray nozzle moves synchronously with the cutting tool. Coolant splashed during shaft turning (coolant sprayed on the shaft is usually splashed out at the turning position, carrying metal chips) is collected by the baffle and gathered in the collection area. The isolation trough laterally divides the collection area. The opening of the first collection pit is flush with the collection area and connects to the isolation trough, located between the baffle and the second collection pit; i.e., the baffle is located on one side of the isolation trough, and the second collection pit is located on the other side. The first collection pit is connected to the second collection pit via an overflow outlet. The second collection pit provides coolant to the outside. The collection area is covered with a sieve plate, which protects the first collection pit and the isolation tank. The coolant collected in the collection area, mixed with iron filings and other impurities, flows to the isolation tank. Most of the iron filings and other impurities are deposited in the collection area during the flow. The coolant mixed with the remaining impurities is filtered by the sieve plate, and most of the remaining impurities are separated by the sieve plate. The coolant carrying small particles of impurities passes through the sieve plate and enters the isolation tank, flowing into the first collection pit. The remaining iron filings and impurities settle at the bottom of the first collection pit, and the clear liquid at the top overflows into the second collection pit, which can be directly recycled as coolant.
[0015] 2. The opening of the second collection pit is higher than the collection area, and the opening of the second collection pit is covered with a cover plate to prevent impurities in the collection area from entering the second collection pit and to ensure the cleanliness of the coolant in the second collection pit.
[0016] 3. A filter cylinder is installed in the first collection pit. The shape of the filter cylinder is adapted to the inner cavity of the first collection pit. The settled iron filings are collected in the filter cylinder. After the first collection pit has been running for a period of time, the filter cylinder can be lifted to separate the settled iron filings, which is convenient for the staff to operate and effectively reduces the intensity of manual labor.
[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0019] In the attached diagram, 1 is the lathe mounting base, 2 is the cofferdam, 3 is the collection area, 4 is the baffle, 5 is the isolation trough, 6 is the first collection pit, 7 is the second collection pit, 8 is the overflow port, 9 is the sieve plate, 10 is the cover plate, and 11 is the transfer pump. Detailed Implementation
[0020] See Figures 1 to 3This is a specific embodiment of a lathe coolant collection and recovery device. The device includes a lathe mounting base 1 elevated above the factory ground level. Typically, the mounting base is made of concrete, and all four side walls are sloped, giving it a trapezoidal cross-section. A dike 2 is installed on the factory ground to the right of the mounting base 1. The dike 2 is spaced apart from the mounting base 1, and its first and last ends are connected to the two ends of one side of the mounting base, forming a closed collection area 3. In this embodiment, the dike is made of concrete, and its height is the same as that of the mounting base 1. The inner side wall of the dike 2 is sloped, and its outer side wall is vertical. The collection area 3 includes a baffle 4, an isolation groove 5, a first collection pit 6, and a second collection pit 7. Specifically, the depth of the second collection pit 7 is less than the depth of the first collection pit 6, and the cross-sectional area of the second collection pit 7 is greater than that of the first collection pit 6. The baffle 4 corresponds to the axial movement range of the cutting tool. The isolation trough 5 laterally divides the collection area 3. That is, one end of the isolation trough is connected to the right side of the lathe mounting base, and the other end is connected to the cofferdam. The ratio of the two sides of the isolation trough can be determined according to the actual situation. The opening of the first collection pit 6 is flush with the collection area 3 and connects to the isolation trough 5. It is located between the baffle 4 and the second collection pit 7. In order to facilitate the cleaning of iron filings and impurities deposited in the first collection trough, a filter cylinder is set in the first collection pit 6. The shape of the filter cylinder is adapted to the inner cavity shape of the first collection pit 6. The first collection pit 6 is connected to the second collection pit 7 through the overflow port 8. The second collection pit 7 provides coolant to the outside. The overflow port of the first collection pit 6 is an open channel or a buried pipe. In this embodiment, the opening of the second collection pit 7 is higher than the collection area 3, and the opening of the second collection pit 7 is covered with a cover plate 10. An open channel is directly set on the collection area as the overflow port of the first collection pit. Of course, a buried pipe can also be set as needed, that is, buried below the collection area as the overflow port. It also includes a transfer pump 11, the inlet of which is connected to the second collection pit 7 via a pipeline and is liquid-sealed, and the outlet of the transfer pump 11 supplies coolant to the lathe via a pipeline. The collection area 3 is covered with a sieve plate 9, which provides protection for the first collection pit 6 and the isolation trough 5.
[0021] The working principle of this invention is as follows: When a lathe is machining a shaft, part of the coolant sprayed onto the shaft is detached from the shaft by centrifugal force and thrown out in a downward direction to the right. Part of the thrown-out coolant (carrying iron filings) is caught by a baffle plate, and part is collected by a collection area. The portion of coolant collected by the baffle plate flows into the collection area. The coolant collected in the collection area, mixed with iron filings and other impurities, flows into an isolation tank. Most of the iron filings and other impurities are deposited in the collection area during the flow. The remaining coolant, mixed with the remaining impurities, is filtered by a sieve plate, and most of the remaining impurities are separated by the sieve plate. The coolant, carrying small particles of impurities, passes through the sieve plate and enters the isolation tank, flowing into the first collection pit. The remaining iron filings and impurities settle at the bottom of the first collection pit, while the clear liquid overflows into the second collection pit and is pumped back to the lathe by a transfer pump, where it can be directly recycled as coolant.
