Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lathes, in particular to a coolant circulation system for a lathe. Background Art
[0002] The coolant circulation system of a lathe is an indispensable part of modern machining. It plays a crucial role in improving machining efficiency, ensuring workpiece accuracy, and extending tool life. This system mainly pumps coolant to the cutting area to reduce the temperature during cutting, lubricate the contact surface between the tool and the workpiece, and at the same time carry away the heat and cutting debris generated by cutting, thereby ensuring the stability and efficiency of the machining process.
[0003] Most of the existing coolant circulation technologies integrate a filtering device, aiming to continuously recycle the coolant while reducing the impact of pollutants. The system usually includes components such as a coolant storage tank, a pump, pipelines, nozzles, and filtration. After the coolant is pumped to the cutting area, it falls with iron filings and other particles, and then is separated in the chip storage tank, and the coolant returns to the coolant storage tank.
[0004] However, one challenge in this circulation process is that the coolant inevitably passes through the iron filing storage area. Although the design strives for efficient iron filing separation, in actual operation, the long-term contact between the coolant and the iron filings is still a problem. The coolant, especially water-based coolant, its chemical composition can accelerate the oxidation process of iron filings, causing the iron filings to rust. These rusty iron filings are not only easy to fall off, but their volume often expands, making it easier to escape from the filtration system and finally enter the interior of the coolant storage tank.
[0005] The mixing of rusty iron filings not only pollutes the coolant, affects its cooling and lubrication performance, but also may clog pipelines and nozzles, increasing maintenance costs, and even causing equipment failures and a decline in machining quality. Of course, to prevent the above situation, the optimal solution is to clean the iron filings every day, but if you forget to clean them, it is easy to cause the above problems. Content of the Utility Model
[0006] Aiming at the deficiencies in the prior art, the utility model provides a coolant circulation system for a lathe, which solves the technical problems that the existing coolant circulation system of a lathe is prone to generate rust and let the rust enter the coolant circulation system.
[0007] According to an embodiment of the utility model, a coolant circulation system for a lathe is provided. The lathe is provided with a bed body, and a chip storage tank is arranged at the bottom of the bed body;
[0008] The coolant circulation system includes a coolant storage tank, a pump body and a nozzle pipe. The pump body is connected to the coolant storage tank and the nozzle pipe through pipelines respectively. The coolant storage tank is arranged on one side of the chip trough, and the nozzle pipe is arranged on the upper side of the chip trough. A turnover box is also arranged between the bed body and the nozzle pipe. The turnover box covers the chip trough, the turnover box is communicated with the coolant storage tank, and the turnover box can be turned over to the side of the chip trough.
[0009] The technical principle of the present utility model is as follows: During normal production and processing, the pump body pumps the coolant in the coolant storage tank to the nozzle pipe, and then sprays it onto the processed parts and cutting tools for cooling and lubrication. Then, the coolant falls onto the turnover box together with the iron chips, and then the coolant flows back into the coolant storage tank through the turnover box, while the iron chips are left on the turnover box. After the processing is completed, the turnover box is turned over 1 - 12 hours later to let the iron chips fall into the chip trough. Because 1 - 12 hours after the processing is completed, the coolant has basically completed the reflux, and the remaining is only the iron chips. At this time, pouring them into the chip trough does not require daily cleaning, and it can be cleaned when the chip trough is full.
[0010] Compared with the prior art, the present utility model has the following beneficial effects: By cooperating the turnover box with the coolant storage tank and the chip trough, it solves the technical problems that the coolant circulation system of the existing lathe is prone to generate rust and let the rust enter the coolant circulation system.
[0011] Further, the turnover box includes a box body and a turnover net. The box body and the turnover net are hinged to each other on the side close to the chip trough. Arc-shaped tracks and horizontal tracks are arranged on both sides of the bed body where the chip trough is located. The arc-shaped tracks are located above the horizontal tracks. Both sides of the box body are stuck on the horizontal tracks, and the side of the turnover net without hinge is stuck into the arc-shaped track.
[0012] Further, the box body is horizontally arranged, the turnover net is inclined, and the included angle between the turnover net and the box body can rotate between 20 - 90°.
[0013] In the rotation range of 20 - 90°, whether it is manually pulling the box body or driving by an electric slide rail, it is very labor-saving.
[0014] Further, a raised column is arranged at the place where the turnover net is stuck into the arc-shaped track, and a roller is arranged at the top of the raised column, and the roller rolls along the arc-shaped track.
[0015] Further, the bottom surface of the box body is set as an inclined surface, which is inclined towards the side of the coolant storage tank, and the lowest point of the inclined surface is communicated with the coolant storage tank.
[0016] Further, a filter screen is arranged at the connection between the box body and the coolant storage tank.
[0017] Further, a rolling ball is provided at the liquid outlet of the nozzle tube. Two or more of the six front views of the rolling ball are provided with liquid channels, and the liquid outlet can wrap the liquid channels on both sides of the rolling ball.
[0018] Further, the number of liquid channels provided in each front view direction of the rolling ball is different from the uniform distribution shape. The uniform distribution shapes include rectangular uniform distribution or circumferential uniform distribution, and the number is 1-6.
[0019] By setting the rotatable rolling ball and cooperating with the liquid channels with different numbers and uniform distribution shapes provided in the six front view directions, the coverage area of the cutting fluid can be changed to adapt to cooling and lubrication of different sizes and shapes.
