It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, boring and boring, etc. CNC machine tools automatically process the parts according to a pre-compiled processing program. We compile the processing route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool, so as to command the machine tool to process parts.

[0032] Reference Figure 1 、 Figure 2 and Figure 3 The utility model provides an embodiment: a spring chuck clamping mechanism for a CNC lathe, comprising a base 1 and a sleeve shell 4. The top of the base 1 is fixedly connected to a fixed shell 3, which can conveniently support the sleeve shell 4. The inner rotatable connection of the sleeve shell 4 is a rotating rod 14, and the outer periphery of the rotating rod 14 is fixedly connected to a worm gear 12. When the worm gear 12 rotates, the rotating rod 14 can be conveniently driven to rotate. The middle part of the sleeve shell 4 is rotatably connected to a worm 11, and the worm 11 and the worm gear 12 are meshed with each other. When the worm 11 rotates, the worm gear 12 can be conveniently driven to rotate. The top of the rotating rod 14 is fixedly connected to a disc 15, and when the rotating rod 14 rotates, the disc 15 will be driven to rotate. The middle part of the disc 15 is rotatably connected to a connecting bracket 16, and the connecting bracket 16 is rotatably connected to the movable plate 5 at one end away from the disc 15. When the disc 15 rotates, the movable plate 5 can be conveniently driven to move by the connecting bracket 16. A fixed rod 17 is fixedly connected to one side of the movable plate 5. When the movable plate 5 moves, the fixed rod 17 is driven to move. The fixed rod 17 is fixedly connected to the end away from the movable plate 5 with a clamping plate 18. When the fixed rod 17 moves, the clamping plate 18 is driven to move, so that the spring collet can be clamped conveniently, thereby preventing the clamping force from gradually weakening when working for a long time, and reducing the labor intensity of the staff.

[0033] Reference Figure 3 and Figure 4One end of the worm 11 is provided with a connecting component 1, which is used to drive the worm 11 to rotate. The connecting component 1 includes a connecting rod 10, which is fixedly connected to one end of the worm 11. When the connecting rod 10 rotates, the worm 11 is driven to rotate at the same time. The end of the connecting rod 10 away from the worm 11 is fixedly connected to a knob 6, which can facilitate the staff to drive the connecting rod 10 to rotate.

[0034] Reference Figure 3 and Figure 5 When the movable plate 24 is moved, the clamping block 9 is driven to move, thereby making the clamping block 9 disengage from the clamping slot 8. When the clamping block 9 is disengaged from the clamping slot 8, the sleeve shell 4 and the fixed shell 3 can be conveniently separated, thereby making it convenient for the staff to overhaul the sleeve shell 4 and reduce the labor intensity of the staff.

[0035] Reference Figure 5 A connecting component 2 is provided on one side of the moving block 22, and the connecting component 2 is used to drive the moving block 22 to move. The connecting component 2 includes a moving rod 21, and the moving rod 21 is fixedly connected to one side of the moving block 22. When the moving rod 21 moves, it will drive the moving block 22 to move at the same time. The end of the moving rod 21 away from the moving block 22 is fixedly connected to a button 20, and the button 20 can facilitate the staff to press the moving rod 21 to move.

[0036] Reference Figure 1 、 Figure 3 and Figure 5 , the side of the movable plate 24 away from the block 9 is fixedly connected to the limit rod 25, and the limit rod 25 is slidably connected to the middle of the fixed shell 3. The limit rod 25 can conveniently limit the movable plate 24, thereby preventing the movable plate 24 from deflecting when moving. One side of the splint 18 is fixedly connected with multiple rubber strips 19. Multiple rubber strips 19 can prevent the splint 18 from deflecting when clamping the spring collet. There are two blocks 9, both of which are slidably connected to the middle of the fixed shell 3. Multiple fastening bolts 2 are provided in the middle of the base 1. Multiple fastening bolts 2 can facilitate the staff to connect and fix the base 1, and then facilitate the connection and fixation of the sleeve shell 4.

[0037] Working principle: When the spring chuck is clamped, the knob 6 is manually driven to rotate. When the knob 6 is rotated, the connecting rod 10 is driven to rotate. When the connecting rod 10 is rotated, the worm 11 is driven to rotate. When the worm 11 is rotated, the worm gear 12 is driven to engage and rotate. When the worm gear 12 is rotated, the rotating rod 14 is driven to rotate at the same time. When the rotating rod 14 is rotated, the disc 15 is driven to rotate. When the disc 15 is rotated, the connecting bracket 16 is driven to move. When the connecting bracket 16 moves, the movable plate 5 is driven to move. When the movable plate 5 moves, the clamping plate 18 is driven to move through the fixed rod 17, so that the spring chuck can be clamped conveniently.

[0038] When it is necessary to separate the fixed shell 3 and the sleeve shell 4, the button 20 is manually pressed to move. When the button 20 moves, the moving rod 21 is driven to move. When the moving rod 21 moves, the moving block 22 is driven to move. When the moving block 22 moves, the movable plate 1 23 is driven to move at the same time. When the movable plate 1 23 moves, the movable plate 2 24 is driven to move. When the movable plate 24 moves, the spring 26 is squeezed. When the movable plate 24 squeezes the spring 26, it drives the card block 9 to move, thereby disengaging the card block 9 from the card slot 8. When the card block 9 is disengaged from the card slot 8, the sleeve shell 4 and the fixed shell 3 can be easily separated.
