[0020] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0021] As Figures 1-4 shown, the present utility model provides a technical solution: a new type of lathe that can quickly switch tool heads, including a lathe main body 1. Inside the lathe main body 1, a mounting seat 2 is slidably installed. On both sides of the inside of the mounting seat 2, limiting slide bars 3 are symmetrically and fixedly installed. And inside the mounting seat 2, between the two groups of limiting slide bars 3, a moving screw rod 4 is rotatably installed. At the central position on one side of the mounting seat 2, a mounting plate 5 is fixedly installed. On the top of the mounting plate 5, a moving motor 6 is fixedly installed. And one end of the moving screw rod 4 close to the moving motor 6 passes through the mounting seat 2 and is fixedly connected to the output end of the moving motor 6. By providing the moving motor 6, starting the moving motor 6 drives the moving screw rod 4 to rotate, thereby controlling the moving seat 7 to drive the mounting bottom block 9 to move on the top of the mounting seat 2, so that the processing tool head 29 can move to a suitable processing position of the processed part.
[0022] On the surface of the moving screw rod 4 located inside the mounting seat 2, there is a moving seat 7. On both sides of the moving seat 7 on the surfaces of the two groups of limiting slide bars 3, limiting slide seats 8 are symmetrically and slidably installed. And the two groups of limiting slide seats 8 are fixedly connected to the moving seat 7. Due to the provision of the limiting slide bars 3 and the limiting slide seats 8, when the moving seat 7 drives the limiting slide seats 8 to move on the corresponding surfaces of the limiting slide bars 3, it is ensured that the mounting bottom block 9 will not tilt or deflect on the top of the mounting seat 2;
[0023] On the top of the moving seat 7 and the two groups of limiting slide seats 8, a mounting bottom block 9 is fixedly installed. On the top of the mounting bottom block 9, a plurality of groups of balls 10 are evenly embedded and rotatably installed. By providing the balls 10, when the rotating seat 13 rotates on the top of the mounting bottom block 9, the balls 10 roll at the bottom of the rotating seat 13, thereby reducing the friction between the mounting bottom block 9 and the rotating seat 13 during relative rotation.
[0024] At the four corners of the top of the mounting bottom block 9, there are positioning slots 11. At the central position on the top of the mounting bottom block 9, a rotating column 12 is rotatably installed. On the top of the rotating column 12, a rotating seat 13 is fixedly installed. At the four corners of the rotating seat 13, there are mounting slots 15. Due to the provision of the rotating column 12, the mounting bottom block 9 and the rotating seat 13 can rotate around the rotating column 12, ensuring that the center will not shift when the mounting bottom block 9 and the rotating seat 13 rotate;
[0025] A positioning insertion rod 16 is slidably installed inside the installation groove 15, and both ends of the positioning insertion rod 16 pass through the installation groove 15 and extend to the outside of the rotating seat 13. A limiting plate 17 is fixedly installed on the surface of the positioning insertion rod 16 inside the installation groove 15. A jacking spring 18 is provided on the surface of the positioning insertion rod 16 at the bottom of the limiting plate 17. The top ends of the four groups of positioning insertion rods 16 pass through the rotating seat 13 and are fixedly installed with a connecting plate 19. By providing the jacking spring 18, under the rebounding action of the jacking spring 18, the limiting plate 17 is jacked up, so that the positioning insertion rod 16 moves upward and retracts into the installation groove 15, facilitating the control of the rotation of the rotating seat 13 on the top of the installation bottom block 9.
[0026] At the central positions on the four sides of the top of the rotating seat 13, there are rectangular grooves 22. On the four sides of the bottom of the connecting plate 19, there are pressing blocks 23 fixedly installed inside the rectangular grooves 22. A pressing pad 24 is fixedly installed at the bottom of the pressing block 23. Three fixing clamping columns 25 are fixedly installed at equal intervals at the bottom of the pressing block 23, and the bottom ends of the fixing clamping columns 25 pass through the pressing pad 24. Due to the provision of the fixing clamping columns 25, after the fixing insertion block 26 is correspondingly inserted into the rectangular groove 22, and the fixing clamping columns 25 are inserted into the corresponding fixing insertion holes 27, the fixing insertion block 26 is clamped and fixed inside the rectangular groove 22.
[0027] An annular sliding groove 14 is provided at the bottom of the rotating seat 13, and the annular sliding groove 14 corresponds to the ball 10. Due to the provision of the annular sliding groove 14, when controlling the rotation of the rotating seat 13 on the top of the installation bottom block 9, the ball 10 rolls inside the annular sliding groove 14, thus ensuring that the ball 10 does not slide randomly at the bottom of the rotating seat 13;
[0028] A fixing stud 20 is fixedly installed at the central position of the top of the rotating seat 13, and a fixing nut 21 is provided at the top of the fixing stud 20 passing through the connecting plate 19. By providing the fixing nut 21, turning the fixing nut 21 enables the connecting plate 19 to press against or move away from the top of the rotating seat 13, facilitating the control of the rotation of the rotating seat 13 on the top of the installation bottom block 9 and the clamping and fixing of the fixing insertion block 26.
[0029] Fixing insertion blocks 26 are respectively provided on the four sides of the rotating seat 13. Three fixing insertion holes 27 are provided at equal intervals at the top of the fixing insertion block 26, and the fixing insertion holes 27 correspond to the fixing clamping columns 25. A tool holder 28 is fixedly installed on one side of the fixing insertion block 26. A processing tool head 29 is provided inside the tool holder 28. Three fixing bolts 30 are provided at equal intervals at the top of the tool holder 28. Due to the provision of the tool holder 28, after the processing tool head 29 is inserted into the tool holder 28, tightening the fixing bolts 30 clamps and fixes the processing tool head 29 inside the tool holder 28, facilitating the connection and fixing of the tool holder 28 and the rotating seat 13.
[0030] The working principle of the present utility model is as follows:
[0031] After inserting the processing tool bit 29 into the tool holder 28, tighten the fixing bolt 30 to fix the processing tool bit 29 inside the tool holder 28. Loosen the fixing sleeve 21, and under the resilience of the jacking spring 18, the connecting plate 19 is jacked up away from the rotating seat 13, so that the pressing block 23 and the fixing clamping column 25 move upward away from the rectangular groove 22, which facilitates the corresponding insertion of the fixing plug 26 into the rectangular groove 22, making the fixing clamping column 25 correspond to the fixing jack 27. Turn the fixing sleeve 21 to press down the connecting plate 19, ensuring that the fixing clamping column 25 is inserted into the corresponding fixing jack 27 and at the same time the positioning rod 16 does not pass through the installation groove 15. Control the rotation of the rotating seat 13 on the top of the installation bottom block 9 according to the processing requirements until the positioning rod 16 corresponds to the positioning slot 11. Tighten the fixing sleeve 21 to press the connecting plate 19 against the top of the rotating seat 13, so that the positioning rod 16 is inserted into the corresponding positioning slot 11, and at the same time the fixing clamping column 25 is completely inserted into the corresponding fixing jack 27. Start the moving motor 6 to control the moving seat 7 to drive the installation bottom block 9 to move on the top of the installation seat 2 until the processing tool bit 29 corresponds to the processing position of the processed part, so as to process the part.
