[0002] In the field of mechanical manufacturing, CNC lathes, as core processing equipment, are widely used in the precision turning of workpieces such as shafts and spiral parts, and are one of the key equipment for the upgrading and development of modern manufacturing.

[0003] Most existing CNC lathes adopt a single machining station design. After machining, the machine needs to be stopped and the workpiece surface and the machining table need to be cleaned manually to remove the remaining cutting chips and cutting fluid.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-9 A CNC lathe includes a machine tool 1, on which a machining component 2, a cleaning mechanism 3, and a collection trough 4 are provided. The machining component 2 includes a machining table 23 and a turning head 24. The machining table 23 is used to place the workpiece and move the workpiece horizontally. The turning head 24 can move vertically. The cleaning mechanism 3 includes a cleaning chamber 31, a sliding bracket 32, a sliding plate 33, a fixed sleeve 36, a cleaning brush 363, and a flushing nozzle 37. Cleaning chambers 31 are provided on both sides of the machine tool 1. A sliding bracket 32 ​​is installed in each cleaning chamber 31. The sliding bracket 32 ​​can move within the cleaning chamber 31. 1. The sliding plate 33 slides horizontally in the direction of the turning head 24. The sliding plate 33 is slidably mounted on the sliding bracket 32. An electric telescopic rod 35 is fixedly mounted on the bottom of the sliding plate 33. The output shaft of the electric telescopic rod 35 is connected to the fixed sleeve 36. The cleaning brush 363 is rotatably mounted on the bottom of the fixed sleeve 36. The rinsing nozzle 37 is connected to the outside of the fixed sleeve 36. After the workpiece that has been processed enters the cleaning chamber 31, the sliding plate 33 drives the cleaning brush 363 to move above the workpiece. The electric telescopic rod 35 pushes the cleaning brush 363 down to clean the workpiece. At the same time, the rinsing nozzle 37 rinses the workpiece.

[0035] In use, two workpieces are first placed at opposite ends of the machining table 23. The machining table 23 then transports one end of the workpiece to the turning head 24 for turning. During the machining process, the machining table 23 moves the workpiece laterally or vertically on the horizontal plane to adjust its machining position under the turning head 24. Simultaneously, the turning head 24 moves vertically up and down to adjust its machining depth. Through the cooperation of the machining table 23 and the turning head 24, a spiral groove is machined into the workpiece, thus turning it into a spiral shape. After the workpiece at that end is machined, the machining table 23 moves the machined workpiece to the cleaning chamber 31, allowing the unmachined workpiece at the other end of the machining table 23 to be moved to the turning head. After the head 24 moves down, the machining table 23 moves in conjunction with the turning head 24, allowing the turning head 24 to process the unprocessed workpiece at the other end of the machining table 23. Simultaneously, when the processed workpiece enters the cleaning chamber 31, the sliding bracket 32 ​​moves towards the processed workpiece, and the sliding plate 33 moves on the sliding bracket 32, moving the cleaning brush 363 directly above the processed workpiece. Then, the electric telescopic rod 35 extends its output shaft downwards, pushing the cleaning brush 363 onto the processed workpiece. During this process, the cleaning brush 363 rotates, cleaning the workpiece, while the rinsing nozzle 37 sprays water to rinse the workpiece. During the cleaning process of the cleaning brush 363, the sliding bracket 32 ​​and the sliding plate 33 move together. The movement of plate 33 controls the movement trajectory of cleaning brush 363, allowing cleaning brush 363 and rinsing nozzle 37 to move on the surface of the spiral workpiece and within the spiral grooves of the workpiece, cleaning the finished workpiece. After cleaning the finished workpiece, the electric telescopic rod 35 retracts its output shaft, lifting cleaning brush 363 from the finished workpiece. Subsequently, sliding bracket 32 ​​drives sliding table to move within cleaning chamber 31, causing rinsing nozzle 37 to rinse the portion of processing table 23 that has entered cleaning chamber 31, thereby cleaning this portion of processing table 23 and the finished workpiece on it. After the workpiece at the other end of processing table 23 is finished, processing table 23 moves the finished workpiece at the other end to the machine. The cleaned workpiece is removed from the cleaning chamber 31 on the other side of the machine tool 1, making it convenient for the worker to take out the cleaned workpiece and place the next workpiece to be processed on the cleaned processing table 23. The worker does not need to clean the processing table 23 after taking out the workpiece to be processed, thereby improving the processing efficiency of the workpiece. After the next workpiece to be processed is placed, the turning head 24 on the machine tool 1 begins to process the next workpiece. At the same time, the workpiece that has been processed at the other end of the processing table 23 is cleaned in the cleaning chamber 31 on the other side of the machine tool 1. The cutting fluid and chips generated during turning, as well as the sewage and chips generated during the cleaning process, are collected together in the collection tank 4 for centralized treatment.

[0036] Furthermore, a positioning ring 351, a sliding ring 352, and a spring seat 353 are sequentially arranged on the outer side of the electric telescopic rod 35. The positioning ring 351 is fixedly installed on the upper end of the electric telescopic rod 35, and the sliding ring 352 is slidably connected to the outer side of the electric telescopic rod 35. Several connecting seats 3521 are fixedly connected to the sliding ring 352, and the several connecting seats 3521 are evenly arranged in a circular shape on the sliding ring 352. The spring seat 353 is fixedly installed on the lower end of the electric telescopic rod 35, and a support spring 354 is sleeved on the outer side of the electric telescopic rod 35. The upper and lower ends of the support spring 354 are fixedly connected to the sliding ring 352 and the spring seat 353, respectively. When the electric telescopic rod 35 fully retracts its output shaft, the support spring 354 pushes the sliding ring 352 to abut against the positioning ring 351.

[0037] Furthermore, a fixing ring 361 is fixedly installed on the outside of the fixing sleeve 36, and several rotating shaft seats 3611 are fixedly connected to the fixing ring 361. The rotating shaft seats 3611 are evenly arranged in a circumferential shape. A stop block 3612 is fixedly connected to the bottom of the fixing ring 361. An electric motor 362 is fixedly installed inside the fixing sleeve 36. The output shaft of the electric motor 362 is fixedly connected to the upper end of the cleaning brush 363. The cleaning brush 363 can be driven to rotate by the electric motor 362.

[0038] During the cleaning of the finished workpiece, the electric telescopic rod 35 extends its output shaft to push the fixed sleeve 36 downward, causing the cleaning brush 363 to move onto the workpiece. At the same time, the electric motor 362 drives the cleaning brush 363 to rotate. The rotating cleaning brush 363 cleans the workpiece with its bristles. In this process, through the cooperation of the sliding bracket 32, the sliding plate 33 and the electric telescopic rod 35, the cleaning brush 363 can penetrate into the spiral groove of the workpiece and move along the spiral groove to clean the inner wall and bottom of the workpiece, so that the workpiece is thoroughly cleaned.

[0039] Furthermore, each rotating shaft seat 3611 is equipped with a flushing nozzle 37, each flushing nozzle 37 is rotatably connected to the rotating shaft seat 3611 via a rotating shaft, and each flushing nozzle 37 corresponds to a connecting seat 3521. A connecting rod 38 is provided between each flushing nozzle 37 and the corresponding connecting seat 3521, and the two ends of the connecting rod 38 are rotatably connected to the flushing nozzle 37 and the connecting seat 3521 respectively.

[0040] Initially, the electric telescopic rod 35 fully retracts its output shaft, and the support spring 354 pushes the sliding ring 352 against the positioning ring 351. This causes the connecting rod 38 to push the flushing nozzle 37 downward, causing it to abut against the stop block 3612, thus keeping the flushing nozzle 37 in a vertically downward position. When cleaning the workpiece, the electric telescopic rod 35 extends its output shaft, allowing the cleaning brush 363 to enter the spiral groove of the workpiece. Simultaneously, as the electric telescopic rod 35 extends its output shaft, it pushes the fixed sleeve 36 downward away from the electric telescopic rod 35. The connecting rod 38 pulls the flushing nozzle 37 upward until the flushing nozzle 37 changes from a vertical to a horizontal position, thus flushing the inner wall of the spiral groove. When the flushing nozzle 37 becomes horizontal, the lower part of the end of the flushing nozzle 37 near the fixed sleeve 36 will abut against... The slide block is stopped at the stop 3612 and cannot continue to rotate upwards. During this process, the support spring 354 does not deform, so the slide block always abuts against the positioning block. As the electric telescopic rod 35 continues to extend its output shaft, the flushing nozzle 37, which can no longer rotate, pulls the sliding ring 352 downwards through the connecting rod 38 and compresses the support spring 354. After cleaning the workpiece, the electric telescopic rod 35 retracts its output shaft, driving the fixed sleeve 36 to move closer to the electric telescopic rod 35, so that the support spring 354 restores its deformation and pushes the sliding ring 352 to abut against the positioning ring 351 again. As the electric telescopic rod 35 continues to retract its output shaft, the connecting rod 38 pushes the horizontal flushing nozzle 37 to rotate downwards, so that the flushing nozzle 37 becomes vertical and abuts against the stop 3612, thereby enabling the cleaning of the processing table 23 below.

[0041] Furthermore, the cleaning chamber 31 is fixedly installed on the side wall of the machine tool 1. An inlet 311 is provided on the side of the cleaning chamber 31 near the turning head 24. A guide rail 312 is fixedly installed on the upper end of the inner side of the cleaning chamber 31. A sliding bracket 32 ​​is slidably installed on the guide rail 312. A moving groove 313 is provided on one side of the cleaning chamber 31. The moving groove 313 is located on one side of the guide rail 312.

[0042] When the workpiece that has been processed is sent from the processing table 23 into the cleaning chamber 31, the workpiece that has been processed on the processing table 23 enters the cleaning chamber 31 through the inlet 311.

[0043] Furthermore, a drive groove 321 is provided on the sliding bracket 32, and bearing seats 322 are provided at both ends of the drive groove 321. Both bearing seats 322 are fixedly installed on the sliding bracket 32. A motor seat 323 is fixedly installed on the side of the sliding bracket 32 ​​near the moving groove 313. Slide tracks 324 are provided at the bottom of both sides of the drive groove 321. Both slide tracks 324 are fixedly installed at the bottom of the sliding bracket 32. The sliding plate 33 is slidably installed on the slide track 324. A connecting block 331 is fixedly installed on the top of the sliding plate 33. A threaded sleeve is fixed on the connecting block 331.

[0044] Furthermore, the cleaning mechanism 3 also includes a servo motor 34 and a drive cylinder 39. The servo motor 34 is fixedly mounted on the motor base 323. A drive rod 341 is coaxially fixedly connected to the output shaft of the servo motor 34. The drive rod 341 is rotatably mounted on the bearing seat 322. The drive rod 341 is a threaded rod. The connecting block 331 is fitted onto the threaded rod through its threaded sleeve. The drive cylinder 39 is fixedly mounted on the side wall of the cleaning chamber 31 away from the turning head 24. The output end of the drive cylinder 39 is fixedly connected to the sliding bracket 32.

[0045] When cleaning the workpiece, the drive cylinder 39 can drive the sliding bracket 32 ​​to slide back and forth along the guide rail 312 in the cleaning chamber 31 by extending and retracting its output shaft. Through the setting of the displacement groove, the servo motor 34 can move synchronously with the sliding bracket 32. The servo motor 34 can rotate forward or backward by driving the drive rod 341, so that the sliding plate 33 slides back and forth along the slide rail 324 with the engagement of the thread.

[0046] Furthermore, the collection tank 4 is installed inside the machine tool 1. The collection tank 4 is used to collect sewage and debris generated during the processing. A drain pipe 41 is fixedly connected to one side of the machine tool 1. The drain pipe 41 is connected to the collection tank 4, and the sewage and debris in the collection tank 4 can be discharged through the drain pipe 41.

[0047] The wastewater and debris collected by the collection tank 4 are discharged from the machine tool 1 through the sewage pipe 41.

[0048] Furthermore, the processing assembly 2 also includes a horizontal electric slide 21 and a vertical electric slide 22. The horizontal electric slide 21 is fixedly installed inside the machine tool 1, and the vertical electric slide 22 is fixedly installed on the horizontal electric slide 21. The processing table 23 is fixedly installed on the vertical electric slide 22, and clamps 231 are fixedly installed on both ends of the processing table 23. When processing a workpiece, the horizontal electric slide 21 can drive the vertical electric slide 22 to move the processing table 23 horizontally on the horizontal plane, and the vertical electric slide 22 can drive the processing table 23 to move vertically on the horizontal plane.

[0049] In the process of processing a workpiece, the workpiece to be processed is placed on the fixture 231 and fixed by the fixture 231. When it is necessary to adjust the position of the workpiece, the horizontal electric slide 21 and the vertical electric slide 22 are driven by the motor to move the workpiece on the processing table 23 to a suitable processing position on the horizontal plane for processing.

[0050] This invention also provides a turning method for the moving plate of an air conditioning compressor, using the aforementioned CNC lathe, with the following specific steps:

[0051] S1. Fix the two workpieces to the two ends of the processing table 23 respectively;

[0052] S2. The machining table 23 moves one end of the workpiece to the turning head 24, and performs turning on the workpiece by the cooperation of the turning head 24 and the machining table 23, thus machining the workpiece into a spiral shape.

[0053] S3. After the workpiece on one end of the machining table 23 is finished, the machining table 23 moves the finished workpiece to the cleaning chamber 31, and at the same time, the machining table 23 moves the workpiece to be processed on the other end of the machining table 23 to the turning head 24.

[0054] S4, the turning head 24 processes the workpiece at the other end of the processing table 23, while the cleaning mechanism 3 cleans the processed workpiece and the processing table 23 entering the cleaning chamber 31 through the cooperation of the cleaning brush 363 and the flushing nozzle 37.
