DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 A rear-mounted turret for a flat bed comprises a moving seat 1, a servo motor 2 is fixedly mounted on the moving seat 1, a cylindrical tool holder 3 is fixedly mounted on the output shaft of the servo motor 2, and a plurality of placement slots are opened at one end of the tool holder 3;

[0024] A cavity 4 is formed inside the tool holder 3, an air inlet hole connected to the cavity 4 is formed at one end of the tool holder 3, a connector 5 connected to the air inlet hole is fixedly mounted at one end of the tool holder 3, and an air supply pipe 6 is rotatably connected to the connector 5;

[0025] A plurality of mounting grooves are provided on the side of the tool holder 3, and an air guide hole 7 connected to the cavity 4 is provided on the inner wall of each of the mounting grooves. A rectangular block 8 is inserted into the mounting groove through a locking assembly, and a spray hole connected to the air guide hole 7 is provided on the rectangular block 8;

[0026] When the workpiece is being cut, the air supply pipe 6 will continuously supply gas into the cavity 4, and then supply the gas into multiple installation grooves through multiple air guide holes 7 respectively. The gas entering the installation groove will enter the spray hole opened in the rectangular block 8, and then be sprayed out from the spray hole. The sprayed gas can blow away the debris accumulated on the tool, avoiding a large amount of debris from accumulating on the tool and affecting the chip cutting, and at the same time making it convenient for the staff to observe the cutting condition of the tool.

[0027] One end of the tool holder 3 is provided with a plurality of threaded holes respectively connected with the plurality of mounting grooves, and the locking assembly comprises a threaded rod 10 threadedly inserted into the threaded hole and a hexagonal block 11 fixedly mounted at one end of the threaded rod 10, and one end of the threaded rod 10 away from the hexagonal block 11 contacts the rectangular block 8;

[0028] When the rectangular block 8 is inserted into the installation groove, the hexagonal block 11 can be rotated by a wrench, thereby driving the threaded rod 10 to rotate, driving one end of the threaded rod 10 to contact the rectangular block 8, applying pressure to the rectangular block 8, and thus installing the rectangular block 8 in the installation groove.

[0029] A sealing tube 9 connected to the spray hole is fixedly connected to the rectangular block 8, one end of which is inserted into the air guide hole 7. The sealing tube 9 is inserted into the air guide hole 7 to increase the sealing between the rectangular block 8 and the air guide hole 7 and prevent gas from leaking out of the installation groove.

[0030] A spherical groove is provided on one side of the rectangular block 8 away from the sealing tube 9, the spherical groove is connected to the spray hole, a rolling ball 12 is rotatably embedded in the spherical groove, a cylindrical hole connected to the spray hole is provided on the rolling ball 12, and a nozzle 13 connected to the cylindrical hole is fixedly connected to the rolling ball 12;

[0031] The ball 12 can rotate in the spherical groove to adjust the gas outlet angle of the nozzle 13. The diameter of the cylindrical hole on the ball 12 is smaller than the diameter of the spray hole. When the ball 12 rotates, the cylindrical holes are connected with the spray holes, so that the gas spray angle can be adjusted according to different tools, so that the sprayed gas can be accurately sprayed on the tool, thereby improving the device's cleaning effect on debris.

[0033] Under the action of the elastic force of the telescopic spring 17, the moving rod 16 drives the limit block 15 to contact the ball 12. The friction between the ball 12 and the limit block 15 will limit the rotation of the ball 12. When the angle of the nozzle 13 needs to be adjusted, the pull rod can be pulled to drive the moving rod 16 to move, thereby driving the limit block 15 to separate from the ball 12.

[0034] In the utility model, when cutting a workpiece, the air supply pipe 6 will continuously supply gas into the cavity 4, and then supply the gas to multiple installation grooves through multiple air guide holes 7 respectively. The gas entering the installation groove will enter the spray hole opened in the rectangular block 8, and then be sprayed out from the spray hole. The sprayed gas can blow away the debris accumulated on the tool, avoiding a large amount of debris from accumulating on the tool and affecting the chip cutting, and at the same time making it convenient for the staff to observe the cutting condition of the tool.

[0035] In general, regarding the technical problem: when debris exists between the tool and the workpiece, it will affect the tool cutting the workpiece to a certain extent, and will also hinder the operator from observing the cutting point of the tool and the workpiece; adopt a technical solution: through the cooperation of the air supply pipe 6, the cavity 4, the air guide hole 7, the rectangular block 8 and the spray hole, during the cutting process, gas is continuously sprayed onto the tool; because the implementation process of the technical solution is: when the workpiece is cut, the air supply pipe 6 will continuously supply gas into the cavity 4, and then the gas will be respectively supplied to the multiple installation grooves through the multiple air guide holes 7, and the gas entering the installation groove will enter the spray hole opened in the rectangular block 8, and then be sprayed out by the spray hole, and the debris accumulated on the tool can be blown away by the sprayed gas; so the technical problem can definitely be solved, and the technical effect achieved is: avoiding a large amount of debris from accumulating on the tool, affecting the chip cutting, and at the same time making it convenient for the staff to observe the tool cutting situation.
