Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC machine tools, and more specifically, to a CNC lathe with a waste chip collection function. Background Technology
[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. CNC machine tools have solved the problem of machining complex, precise, small-batch, and multi-variety parts. They are flexible and high-efficiency automated machine tools. CNC lathes are one type of CNC machine tool.
[0003] During operation, CNC lathes generate a large amount of waste chips. When machining products with high precision, cutting fluid is sprayed from nozzles to cool the product and cutting tools. At the same time, the cutting fluid also washes the waste chips away from the product to prevent them from affecting the machining process. However, the used cutting fluid mixes with the waste chips and accumulates inside the CNC lathe, making it difficult to clean and collect the waste chips and cutting fluid inside the machine tool. This hinders the recycling of cutting fluid and waste chips and can easily cause damage to the internal components of the CNC lathe. Utility Model Content

[0022] Examples of embodiments of this utility model Figures 1 to 6As shown, a CNC lathe with a waste chip collection function includes a base box 1, a lathe body 2 on the top of the base box 1, and a waste chip collection mechanism inside the base box 1. The collection mechanism includes a cylindrical separation box 3, which is rotatably mounted inside the base box 1. A partition 32 is provided inside the separation box 3, dividing the separation box 3 into a semi-circular waste chip cavity 30 and a semi-circular liquid cavity 31. A first filter screen 4, which covers the waste chip cavity 30 and the liquid cavity 31, is detachably installed near the top surface inside the separation box 3. The first filter screen 4 includes a frame and a screen plate. The frame covers the screen plate. Multiple threaded holes are provided on the surface of the frame opposite to the inner wall of the separation box 3. Multiple separation box through holes are provided on the inner wall of the separation box 3. Screws pass through the separation box through holes and are threaded into the corresponding threaded holes. The first filter screen 4 is detachably mounted in the separation box 3 by means of a threaded connection. The first filter screen 4 has a filter notch 41 located directly above the waste chip chamber 30. Preferably, the filter notch 41 is a fan-shaped annular structure with the center of the first filter screen 4 as the center, and the central angle of the filter notch 41 is less than 180 degrees. The base box 1 is provided with a scraper 40 that abuts against the top surface of the first filter screen 4. The scraper 40 is parallel to the partition 32 and located directly above the partition 32, that is, the scraper 40 and the partition 32 are coplanar. Both ends of the extension direction of the scraper 40 abut against the inner wall of the separation box 3. The base box 1 is also provided with a drive mechanism that drives the separation box 3 and the first filter screen 4 to rotate synchronously relative to the scraper 40. The lathe body 2 is provided with a body through hole that allows cutting fluid and waste chips to enter the first filter screen 4 above the liquid chamber 31.
[0023] After the cutting fluid and waste chips enter the liquid chamber 31 through the through hole of the main body and onto the first filter screen 4, the first filter screen 4 separates the cutting fluid and waste chips. The cutting fluid enters the liquid chamber 31, while the waste chips remain on the first filter screen 4. After the machining is completed, the drive mechanism drives the separation box 3 and the first filter screen 4 to rotate synchronously relative to the scraper 40. The scraper 40 scrapes the waste chips on the first filter screen 4 from the filter notch 41 into the waste chip chamber 30, thereby completing the separate collection of waste chips and cutting fluid. This facilitates the recycling of waste chips and cutting fluid, saves costs, and also avoids the accumulation of waste chips and cutting fluid in the CNC lathe, which could cause damage to the internal components of the CNC lathe.

The cutting fluid tank 5 is also a cylindrical structure. The separation box 3 has a connecting channel 34 connected to the cutting fluid tank 5 in the liquid cavity 31. The connecting channel 34 is located on the bottom surface of the liquid cavity 31. The connecting channel 34 is a through hole structure or a tubular structure. By increasing the capacity of the cutting fluid tank 5, more cutting fluid can be collected.
[0025] Further improvements, such as Figure 1 and Figure 2 As shown, the driving mechanism includes a motor 6. A protrusion 50 is provided inside the cutting fluid tank 5, located directly below the center of the separation tank 3. A cavity 51 is provided inside the protrusion 50. The motor 6 is located inside the cavity 51 of the protrusion 50. The output shaft of the motor 6 passes through the protrusion 50 and connects to the center of the bottom surface of the separation tank 3. The protrusion 50 and the cavity 51 accommodate the motor 6 without affecting the cutting fluid tank 5's capacity to hold cutting fluid. The motor 6 drives the separation tank 3 and the first filter screen 4 to rotate synchronously relative to the scraper 40. The protrusion 50 has a cylindrical structure. A sleeve 7 is provided on the bottom surface of the separation tank 3, which is fitted onto the protrusion 50. A sealing ring 70 is provided between the sleeve 7 and the protrusion 50. The sleeve 7 and the sealing ring 70 prevent cutting fluid from entering the cavity 51, thereby preventing damage to the motor 6.
[0026] Further improvements, such as Figure 1 , Figure 3 and Figure 4 As shown, a drawer 8 is slidably mounted on the side wall of the base box 1.
