Then, the protective cover is covered so that the protective cover closes the working space. Then, the rotation of the clamp of the lathe is controlled by the control box of the lathe, thereby driving the long workpiece to rotate, making it convenient for the tool of the lathe to process the long workpiece. The long workpiece is clamped by the tailstock, and when the tailstock is moved to the left, the tailstock drives the cleaning mechanism to move to the left, so that the left end of the cleaning mechanism contacts the left wall of the working space of the main body. After the long workpiece is fixed by the clamp and the tailstock, the long workpiece is processed by the tool, and the generated debris falls on the inner bottom wall of the working space. Part of the debris falls directly into the collecting trough, and the other part falls on the inner bottom wall of the working space outside the guide rail. Part of the debris that falls on the outside of the guide rail directly enters the blanking hole through the top of the blanking hole, and is discharged from the bottom of the blanking hole.

When the tail stock moves to the left, the cleaning block will first contact the left side wall of the working space. At this time, if the tail stock has not yet collided with the right end of the workpiece, the tail stock can continue to move to the left until it collided with the right end of the workpiece. When the tail stock continues to move to the left, the cleaning block and the guide rod no longer move and remain stationary. At this time, the tail stock drives the fixed block to move to the left, and the fixed block slides to the left on the guide rod relative to the guide rod and stretches the spring. Through the design of the spring, the cleaning block can contact the left side wall of the working space in advance without affecting the tail stock to continue to move to the left.

A guide groove is opened, and the tailstock 5 is slidably connected to the main body 1 through the guide rail 6 and the guide groove. A collecting groove 7 is opened on the inner bottom wall of the working space 2 located between the two guide rails 6 along the length direction of the guide rail 6, and a plurality of drop holes 8 are opened on the inner bottom wall of the working space 2 located outside the two guide rails 6. The drop holes 8 are evenly arranged along the left and right directions. The top end of the drop hole 8 is opened on the inner bottom wall of the working space 2, and the bottom end of the drop hole 8 is opened on the side wall of the collecting groove 7. Cleaning mechanisms are provided on the front and rear sides of the tailstock 5.

[0035] When in use, the workpiece is clamped by the clamp 4. For a long workpiece, the tailstock 5 is used to assist in clamping the long workpiece. The specific operation method is to move the tailstock 5 to the left so that the ejector pin on the tailstock 5 contacts the right end of the long workpiece, and the left end of the long workpiece is clamped by the clamp 4. Then, the protective cover 3 is covered so that the protective cover 3 closes the working space 2. Then, the control box of the lathe is used to control the rotation of the clamp 4 of the lathe, thereby driving the long workpiece to rotate, making it convenient for the lathe tool to process the long workpiece. When the long workpiece is clamped by the tailstock 5 and the tailstock 5 is moved to the left, the tailstock 5 drives the cleaning mechanism to move to the left, so that the left end of the cleaning mechanism contacts the left side wall of the working space 2 of the main body 1. After the long workpiece is fixed by the clamp 4 and the tailstock 5, the long workpiece is processed by the tool, and the generated debris falls on the inner bottom wall of the working space 2. Part of the debris falls directly into the collecting trough 7, and the other part falls on the inner bottom wall of the working space 2 outside the guide rail 6. Part of the debris that falls on the outside of the guide rail 6 directly enters the blanking hole 8 through the top of the blanking hole 8 and flows out from the bottom of the blanking hole 8. The end of the long workpiece slides out and falls into the collecting trough 7, and another part of the debris that falls to the outside of the guide rail 6 is retained on the inner bottom wall of the working space 2 outside the guide rail 6; when the long workpiece is processed, it is necessary to unload the long workpiece from the lathe, first open the protective cover 3, and then move the tailstock 5 to the right side, so that the ejector of the tailstock 5 is out of contact with the right end of the long workpiece, and while moving the tailstock 5 to the right side, the cleaning mechanism is driven to move to the right side synchronously, so that the cleaning mechanism scrapes the debris on the inner bottom wall of the working space 2 outside the guide rail 6 into the blanking hole 8; thereby achieving the purpose of collecting the debris generated during lathe processing into the collecting trough 7. The movement of the cleaning mechanism is driven by the tailstock 5, and there is no need to add an additional power device, which saves energy. When processing a short workpiece, when the auxiliary clamping of the tailstock 5 is not required, when the short workpiece is clamped on the fixture 4, the tailstock 5 also needs to be moved to the left so that the left end of the cleaning mechanism contacts the left side wall of the working space 2. When the short workpiece is processed, the tailstock 5 is moved to the right. Similarly, the tailstock 5 drives the cleaning mechanism to move to the right, thereby allowing the cleaning mechanism to scrape the debris on the inner bottom wall of the working space 2 outside the guide rail 6 into the blanking hole 8. The cleaning mechanism is also applicable to the processing of short workpieces.

[0036] In order to achieve the purpose of enabling the cleaning mechanism to completely clean the debris on the inner bottom wall of the working space 2 outside the guide rail 6 into the drop hole 8, in this embodiment, the rear side of the top of the drop hole 8 is aligned with the front side of the lower end face of the guide rail 6, and the front side of the drop hole 8 is aligned with the front side of the inner bottom wall of the working space 2 of the main body 1; when the cleaning mechanism cleans the debris on the inner bottom wall of the working space 2 outside the guide rail 6 from left to right, the debris on the inner bottom wall of the working space 2 outside the guide rail 6 will completely enter the drop hole 8 and slide into the collection trough 7.

[0037] The cleaning mechanism includes a cleaning block 9 whose lower end face is in contact with the inner bottom wall of the working space 2, and a guide rod 10 is provided on the right side of the cleaning block 9, and the right end of the guide rod 10 is connected to the tailstock 5; when in use, when the tailstock 5 moves to the left to collide with the workpiece, the cleaning block 9 is driven to move to the left by the guide rod 10, and when the tailstock 5 moves to the left to collide with the workpiece, the left side of the cleaning block 9 contacts the left side wall of the working space 2; then the lathe processes the workpiece, and when the workpiece is processed, the protective cover 3 is opened, and the tailstock 5 moves to the right The tailstock 5 is moved to the right by the guide rail 6, so that the ejector pin of the tailstock 5 is separated from the workpiece, and then the clamp 4 of the lathe is released to take out the workpiece. When the tailstock 5 is moved to the right, the tailstock 5 drives the cleaning block 9 to move to the right through the guide rod 10, so that the lower end surface of the cleaning block 9 slides to the right on the inner bottom wall of the working space 2 located outside the guide rail 6, and then the cleaning block 9 cleans the debris on the inner bottom wall of the working space 2 located outside the guide rail 6, so that the debris is scraped into the top end of the blanking hole 8, and slides out from the bottom end of the blanking hole 8 and falls into the collecting trough 7.

[0038] Since the lengths of the workpieces are different, when the tailstock 5 moves to the left to contact the right end of the workpiece, the moving distance of the tailstock 5 is also different. In order to ensure that the cleaning block 9 can still contact the left side wall of the working space 2 when the tailstock 5 moves to the left by different distances, in this embodiment, a fixed block 11 is fixedly provided on the side wall of the tailstock 5 at a position corresponding to the guide rod 10, and the right end of the guide rod 10 passes through the fixed block 11 and extends to the right side of the fixed block 11, and a baffle 12 is fixedly provided, and a spring 13 is sleeved on the guide rod 10 between the fixed block 11 and the baffle 12, and the left end of the spring 13 is fixedly provided with the fixed block 11, and the right end of the spring 13 is fixedly provided with the baffle 12; when the tailstock 5 moves to the left, the fixed block 11 is driven to move to the left, and the fixed block 11 drives the guide rod 10 to move to the left through the spring 13 and the baffle 12, and the guide rod 10 drives the cleaning block 9 to move to the left. When the tail stock 5 moves to the left, the cleaning block 9 will first contact the left side wall of the working space 2. At this time, if the tail stock 5 has not yet collided with the right end of the workpiece, the tail stock 5 can continue to be moved to the left until it conflicts with the right end of the workpiece. When the tail stock 5 continues to be moved to the left, the cleaning block 9 and the guide rod 10 no longer move and remain stationary. At this time, the tail stock 5 drives the fixed block 11 to move to the left, and the fixed block 11 slides to the left on the guide rod 10 relative to the guide rod 10 and stretches the spring 13; through the design of the spring 13, the cleaning block 9 can contact the left side wall of the working space 2 in advance, and does not affect the tail stock 5 to continue to move to the left.

[0039] In order to achieve the purpose of cleaning the debris between the cleaning block 9 and the guide rail 6 into the drop hole 8, in this embodiment, the guide rail 6 is an inverted trapezoid, and the adjacent side surfaces of the two cleaning blocks 9 are in contact with the corresponding side walls of the guide rail 6; when the cleaning block 9 moves to the right, the cleaning block 9 cooperates with the side wall of the guide rail 6, so that the debris on the inner bottom wall of the working space 2 located outside the guide rail 6 can be completely pushed and enter the collection trough 7 through the drop hole 8.

[0040] In order to facilitate the collection and recovery of the debris in the collecting trough 7, in the present embodiment, a discharge chute 14 is provided on the right side of the inner bottom wall of the collecting trough 7, a hydraulic telescopic rod 15 is provided inside the tailstock 5, and a scraper 16 is provided at the output end of the hydraulic telescopic rod 15, and the lower end surface of the scraper 16 contacts the inner bottom wall of the collecting trough 7; when the debris in the collecting trough 7 needs to be recovered, the scraper 16 is driven to move to the right side by the contraction of the hydraulic telescopic rod 15, so that the scraper 16 moves from left to right on the inner bottom wall of the collecting trough 7, so that the scraper 16 pushes the debris in the collecting trough 7 to the right side of the collecting trough 7, and makes the debris slide out of the discharge chute 14, so as to achieve the purpose of recovering the debris in the collecting trough 7.

[0041] In order to facilitate the recovery of the debris that slides out of the discharge chute 14, in this embodiment, a base 17 is provided on the lower end surface of the main body 1, and a drawer 18 is slidably connected to the interior of the base 17 in the front-to-back direction. When the drawer 18 slides backward and completely enters the base 17, the top opening of the drawer 18 is connected to the bottom end of the discharge chute 14; when in use, when the debris slides out of the discharge chute 14, it falls into the drawer 18. When there are enough debris in the drawer 18, the drawer 18 is pulled out, and then the debris in the drawer 18 is recovered and processed centrally.

[0042] The working principle of the utility model is that when processing a workpiece, the workpiece is first clamped on the fixture 4, and then the tailstock 5 is moved to the left side so that the ejector pin of the tailstock 5 contacts the right end of the workpiece. At the same time, the tailstock 5 drives the cleaning block 9 to move to the left side through the fixing block 11, the spring 13 and the guide rod 10, so that the left side of the cleaning block 9 contacts the right side of the working space 2, and then the protective cover 3 is covered to make the working space 2 in a sealed state to prevent debris from splashing. Then, the lathe is started through the control box to process the workpiece. After the processing is completed, the protective cover 3 is opened, and the tailstock 5 is moved to the right side so that the cleaning block 9 is driven Move to the right to clean the debris on the inner bottom wall of the working space 2 outside the guide rail 6, so that the debris enters the drop hole 8 and slides into the collecting trough 7. When processing the workpiece, a large part of the debris generated will fall directly into the collecting trough 7 below. When the debris in the collecting trough 7 is recovered, the scraper 16 is driven to move to the right on the inner bottom wall of the collecting trough 7 by contracting the hydraulic telescopic rod 15, so that the scraper 16 scrapes the debris in the collecting trough 7 into the discharge chute 14 and slides into the drawer 18, and then the drawer 18 is pulled out, so that the debris in the drawer 18 can be recovered and processed centrally.
