DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0019] Reference Figure 1 , 2 , which is the first embodiment of the utility model, and provides a lathe-grinding compound machine tool that is convenient for cleaning debris, including a base 1, a collecting tank 2 is fixedly connected to the top of the base 1, a plurality of connecting plates 3 are fixedly connected to the top of one side of the collecting tank 2, one end of the connecting plate 3 is fixedly connected to a slide 4, a fixed headstock 5 is slidably installed on one side of the top of the slide 4, and a fixed tailstock 6 is slidably installed on the other side;

[0020] A fixing seat 7 is fixedly installed on the top of the other side of the collecting tank 2, a grinding seat 8 is installed on one side of the top of the fixing seat 7, a servo motor 9 is installed on the top of the grinding seat 8, the output shaft of the servo motor 9 is fixedly connected to the grinding wheel 10, and a motor 13 is fixedly installed on the other side of the top of the fixing seat 7, and the output shaft of the motor 13 is fixedly connected to the eight-station turret 12;

[0021] Scrapers 16 are slidably provided on both sides of the collecting trough 2, and one side of the scraper 16 is sleeved with a bidirectional screw 17 through a threaded structure. The bidirectional screw 17 is rotatably connected to the collecting trough 2 and one end of the bidirectional screw 17 is fixedly connected to the output shaft of the transmission motor 18. The transmission motor 18 is fixedly installed outside the collecting trough 2, and the other side of the scraper 16 is slidably sleeved with a guide rod and the two ends of the guide rod are respectively fixedly connected to the collecting trough 2. A chip discharge port 19 is opened at the middle bottom end of the collecting trough 2.

[0022] According to the length of the workpiece to be processed, the two ends of the workpiece are abutted against each other by the fixed tailstock 6 and the fixed headstock 5, so as to realize the clamping and fixing of the workpiece. The motor 13 drives the eight-station turret 12 to work to realize the turning of the workpiece. The multiple tools can meet the multiple process requirements of the workpiece at the same time. The servo motor 9 drives the grinding wheel 10 to rotate in a circle, and the grinding wheel 10 realizes the grinding operation of the workpiece, so that the machine tool realizes the functions of turning and grinding in one, which can meet the finishing and roughing of the workpiece at the same time, and can greatly reduce the clamping times of the workpiece. In the case of one clamping, finishing can be directly carried out after roughing, which greatly guarantees the workpiece. Concentricity increases processing efficiency. The debris generated by processing falls into the collecting trough 2 for collection. When cleaning is needed, the transmission motor 18 is started, and the transmission motor 18 drives the fixed bidirectional screw 17 to rotate. The bidirectional screw 17 drives the scrapers 16 on both sides to move toward the chip discharge port 19. The scrapers 16 slide in contact with the bottom wall of the collecting trough 2, and then scrape and clean the debris in the collecting trough 2. The scraped debris finally falls into the chip discharge port 19, and then is blocked by the baffle 20, so that the debris falls into the chip conveyor 14. The chip conveyor 14 transmits the fallen debris, and finally the transmitted debris falls into the collection box for centralized collection. Example

[0023] Reference Figure 1-3 , which is the second embodiment of the utility model, is based on the previous embodiment. Specifically, the inner walls on the four sides of the chip discharge port 19 are respectively fixedly connected with baffles 20, and the baffles 20 form a rectangular opening structure that is wide at the top and narrow at the bottom, thereby blocking the chips falling into the chip discharge port 19 and allowing the chips to fall into the chip conveyor 14 in a concentrated manner.

[0024] Specifically, a chip conveyor 14 is provided at the bottom of the chip discharge port 19, and a collecting box 15 is provided on the side of the chip conveyor 14 away from the chip discharge port 19. The chip conveyor 14 transfers the fallen chips, and the transferred chips finally fall into the collecting box for centralized collection.

[0025] Specifically, the connecting plate 3 is an L-shaped structure. The L-shaped structure allows a certain gap between the slide 4 and the collecting trough 2, ensuring that the connecting plate 3 supports the slide 4 while allowing the processed debris to fall smoothly into the collecting trough 2 for collection.

[0026] Specifically, a protective shell 11 is provided outside the grinding wheel 10, and the protective shell 11 is fixedly connected to the servo motor 9. The protective shell 11 protects the grinding wheel 10 to prevent debris from splashing under the action of centrifugal force during the grinding work of the grinding wheel 10. The protective shell 11 blocks the debris and allows the debris to fall smoothly into the collection tank 2. Example

[0027] Reference Figure 1-3, which is the third embodiment of the utility model, and this embodiment is based on the above two embodiments. The main function of the utility model is to process the workpiece shaft after heat treatment, because the workpiece will produce certain thermal deformation after heat treatment, and the workpiece after thermal deformation will increase the workload of rough grinding. When using this machine tool for processing, the turret can be used for direct rough processing, which greatly reduces the time of rough grinding and improves work efficiency; when using it, according to the length of the workpiece to be processed, the two ends of the workpiece are abutted by the fixed tailstock 6 and the fixed headstock 5, so as to achieve the clamping and fixing of the workpiece, and the motor 13 drives the eight-station turret 12 to work to achieve the turning of the workpiece. Multiple tools can meet multiple process requirements of the workpiece at the same time, and the servo motor 9 drives the grinding wheel 10 to rotate in a circle, and the grinding wheel 10 realizes the grinding operation of the workpiece, so that the machine tool can realize the function of turning and grinding in one. It can simultaneously meet the needs of fine machining and rough machining of the workpiece, which can greatly reduce the number of clamping times of the workpiece. In the case of one clamping, fine machining can be carried out directly after rough machining, which greatly ensures the concentricity of the workpiece and increases machining efficiency. The debris generated by machining falls into the collecting trough 2 for collection. When cleaning is required, the transmission motor 18 is started, and the transmission motor 18 drives the fixed bidirectional screw 17 to rotate. The bidirectional screw 17 drives the scrapers 16 on both sides to move toward the chip discharge port 19. The scrapers 16 slide in contact with the bottom wall of the collecting trough 2, and then scrape and clean the debris in the collecting trough 2. The scraped debris finally falls into the chip discharge port 19, and then is blocked by the baffle 20, so that the debris falls into the chip conveyor 14, and the chip conveyor 14 transmits the fallen debris, and finally the transmitted debris falls into the collection box for centralized collection.
