[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figures 1 to 6 As shown, an internal groove processing device for a lathe comprises a processing box 1, a chuck 3 rotatably arranged on an inner wall of one side of the processing box 1, and a tool holder 5 arranged in an L shape on the side of the chuck 3 facing the center of the processing box 1, a tool head 15 corresponding to the chuck 3 is installed at one end of the tool holder 5, and a pushing component is arranged between the other end of the tool holder 5 and the inner wall of the back end of the processing box 1;

[0025] The propulsion component includes a rectangular cabinet 6 slidably disposed between the inner walls on the left and right sides of the processing box 1, the side of the rectangular cabinet 6 facing the tool holder 5 is open, a screw rod 11 is rotatably disposed between the inner walls on both sides of the tool holder 5, a tool holder 14 is threadedly connected to the screw rod 11, the tool holder 14 is slidably connected to the inner wall of the rectangular cabinet 6, and the tool holder 14 is fixedly connected to the tool holder 5;

[0026] The left and right sides of the processing box 1 are respectively provided with sliding grooves adapted to the rectangular cabinet 6, and the two ends of the rectangular cabinet 6 are respectively slidably arranged in the two sliding grooves, and one end of the screw 11 rotates to pass through the rectangular cabinet 6 and is tightly sleeved with the turntable 7;

[0027] A small motor 4 is installed on one side of the processing box 1, and the output shaft of the small motor 4 rotates and penetrates into the processing box 1 and is fixed to the center of the chuck 3;

[0028] A large motor 10 is installed on the bottom surface of the processing box 1. The output shaft of the large motor 10 rotates from bottom to top and penetrates into the processing box 1 and is threadedly connected with a lifting column 9. The lifting column 9 is vertically fixed on the bottom surface of the rectangular cabinet 6.

[0029] By setting the pushing component, when it is necessary to process the inner groove of the workpiece, the workpiece can be clamped by the chuck 3, the small motor 4 is started, and the workpiece on the chuck 3 is driven to rotate rapidly, and then the large motor 10 is started. During this process, the output shaft of the large motor 10 drives the lifting column 9 and the rectangular cabinet 6 to rotate forward, but the rectangular cabinet 6 is restricted by the sliding groove on the side wall of the processing box 1, causing the lifting column 9 to extend the output shaft of the large motor 10 to make an axial upward movement, pushing the rectangular cabinet 6 to rise, and then pushing the tool holder 5 and the cutter head 15 to rise to the same height as the center of the inner hole of the workpiece, and then rotating the turntable 7 to drive the rotation of the screw 11. During this process, the tool holder 14 is engaged with the screw 11 but is restricted by the open inner wall of the rectangular cabinet 6, causing the tool holder 14 to move along the screw 11 toward the workpiece on the chuck 3, and push the cutter head 15 on the tool holder 5 into the inner hole of the workpiece, and then the large motor 10 is started to reverse so that the cutter head 15 contacts the workpiece after the inner hole of the workpiece descends to complete the cutting process.

[0030] However, in reality, since the rectangular cabinet 6 is open toward the workpiece on the chuck 3, debris splashes into the rectangular cabinet 6 during workpiece processing, and some of the debris gets stuck between the teeth of the screw 11, causing the threaded engagement between the tool holder 14 and the screw 11 to be obstructed and the threads of the screw 11 and the tool holder 14 to be damaged.

[0031] In view of this, in order to solve the above problem, a winding and covering assembly is provided in the opening of the rectangular cabinet 6 for preventing the debris splashed during the processing of the workpiece from entering the rectangular cabinet 6 .

[0032] The winding and covering assembly includes two winding boxes 12 respectively mounted on the inner walls of both sides of the open end of the rectangular cabinet 6, a rotating rod 18 is rotatably arranged between the inner walls of the upper and lower ends of the winding box 12, and the anti-scalding cloth 13 is rolled up on the rod body of the rotating rod 18, and the end of the anti-scalding cloth 13 passes through the winding box 12 and is fixedly connected to a side wall of the knife seat 14;

[0033] Torsion springs 17 are sleeved on both ends of the rotating rod 18, one end of the torsion spring 17 is fixed to the inner wall of the winding box 12, and the other end of the torsion spring 17 is fixed to the rotating rod 18;

[0034] By setting the winding and covering component, the anti-scalding cloths 13 on both sides are pulled and unfolded and fixed on the knife seat 14. At this time, the force of the unfolding of the anti-scalding cloths 13 drives the rotating rod 18 and the torsion spring 17 to rotate synchronously. When the knife seat 14 moves to one side, the reverse force of the torsion spring 17 at both ends of the side causes the rotating rod 18 to drive the anti-scalding cloth 13 to rotate and reset, and rewind the unfolded anti-scalding cloth 13 on this side onto the rod body of the rotating rod 18 on this side. The anti-scalding cloth 13 on the other side is further unfolded and drives the rotating rod 18 to rotate synchronously due to the pulling of the knife seat 14. Then, the anti-scalding cloth 13 is unfolded or rolled up synchronously with the movement of the knife seat 14 to cover the opening of the rectangular cabinet 6, thereby solving the problem in the prior art that the debris splashed during the workpiece processing enters the rectangular cabinet 6 and gets stuck on the screw 11, causing damage to the teeth of the screw 11 and the knife seat 14.

[0035] After the equipment was used for a period of time, it was found that the high temperature generated by the cutter head 15 when processing the workpiece was transmitted to the cutter seat 14 through the cutter holder 5, causing the anti-scalding cloth 13 on both sides of the cutter seat 14 to be damaged by the high temperature for a long time.

[0036] Therefore, in order to solve the above problem, an oil nozzle 16 is installed on the side of the tool holder 5 away from the chuck 3, an oil channel 8 is provided in the tool holder 5, the oil nozzle 16 is connected to the oil channel 8, and an oil outlet corresponding to the oil channel 8 is opened on the side of the tool holder 5 close to the cutter head 15, and an oil hole corresponding to the oil outlet is penetrated on the blade of the cutter head 15.

[0037] By setting the oil delivery nozzle 16 and the oil channel 8, when the workpiece needs to be processed, the oil delivery nozzle 16 can be connected to the cutting oil pump through a hose. When the cutting oil passes through the oil channel 8 in the tool holder 5, the oil cooling effect of the cutting oil can be utilized. The heat energy generated by the cutter head 15 cutting the workpiece during the processing can be cooled by the cutting oil in the oil channel 8 when it is transferred to the tool holder 5, thereby preventing the heat from being transferred from the tool holder 5 to the tool seat 14, causing the anti-scalding cloth 13 on both sides of the tool seat 14 to be damaged by high temperature. At the same time, when the cutting oil enters the oil outlet through the oil channel 8 and overflows through the oil hole of the cutter head 15, it can cool the cutter head 15 and also have a lubricating effect on the processing of the cutter head 15 and the workpiece.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
