The feed motor 220 drives the first wheel 230 to rotate, the first wheel 230 drives the second wheel 240 to rotate, the feed bar 250 rotates synchronously with the second wheel 240, and the rotation of the feed bar 250 drives the feed chuck 210 to drive the workpiece 900 to move forward due to the threaded transmission between the feed chuck 210 and the feed bar 250. After the workpiece 900 is advanced a predetermined distance, it is brought into contact with the jaws in the spin chuck 630, and the jaws of the spin chuck 630 hold the workpiece 900 in the center of the spin chuck 630. The driving motor 610 rotates to drive the driving wheel 621 to rotate, the driving wheel 621 drives the driven wheel 622 to rotate through the driving belt 624, and the rotation of the driven wheel 622 drives the rotation chuck 630 to rotate due to the gear transmission of the driven wheel 622 and the rotation chuck 630, so that the workpiece 900 is driven to rotate; the rotation of the adjusting motor 731 drives the adjusting gear 732 to rotate, but at this time, the top block 735 in the limit groove 734 opposite to the adjusting gear 732 is flush with one side of the first lever 733 facing the adjusting gear 732, so that the limit groove 734 is blocked, the adjusting gear 732 cannot be meshed with the limit groove 734, and the vertical heights of the adjusting motor 731 and the adjusting gear 732 are not changed. The laser generator 300 emits a laser beam to perform a cutting process on the workpiece 900.
When the workpiece 900 moves forward, the workpiece 900 collides with one end of the probes 410 toward the workpiece 900, and the plurality of probes 410 move synchronously in the radial direction of the through hole 111 under the action of the synchronizing assembly 500.
When the diameter of the workpiece 900 becomes larger, the probe 410 is far away from the center of the through hole 111, the transmission frame 738 is driven to move downwards through the connection assembly 800, the first transmission wheel 741 and the second transmission wheel 742 are driven to rotate clockwise when the transmission frame 738 moves downwards, the second rod 736 is driven to move upwards, when the second rod 736 moves upwards, the push block 737 moves upwards synchronously with the second rod 736, the push block 735 which is separated from the push block 737 is moved inwards of the first rod 733, the limit groove 734 is reserved, the push block 735 which is contacted with the push block 737 seals the limit groove 734, the adjusting gear 732 can be meshed with part of the limit groove 734, the adjusting gear 732 moves upwards through the anticlockwise rotation of the adjusting motor 731, the shaft seat 710 is driven by the adjusting rod 739, the shaft seat 710 moves upwards through the adjusting gear 621, the shaft seat 710 and the shaft seat 621 are coaxially arranged, the two driving wheels 621 are connected through the telescopic synchronous rods, the two driving wheels 621 and the two driving wheels 710 move upwards synchronously, the distance between the upper ends of the front and the rear sets of the slide grooves 112 is larger than the distance between the lower ends of the driving wheels 621, the two driving wheels are enabled to move upwards, the rotation speed of the driving wheels is reduced, and the rotation speed of the rotating speed of the workpiece is reduced due to the fact that the rotation speed of the driving wheels is reduced, and the rotation speed of the rotating speed of the driving wheels is reduced relative to the driving wheels is not to the rotation speed of the driving wheels 900 is reduced.
When the diameter of the workpiece 900 is reduced, the probe 410 is close to the center of the through hole 111, and the rotation speed of the workpiece 900 is increased through the connecting assembly 800, the adjusting mechanism 700 and the rotating assembly 600, so that the moving speed of the laser beam on the surface of the workpiece 900 is unchanged, the quality of the notch is improved, and the normal operation of the subsequent process is ensured.
In the above process, the distances of the downward movement of the plurality of probes 410 are different, and the adjusted transmission ratios are different, so that when the workpieces 900 made of different materials are processed, an operator can select the connection assemblies 800 under the different probes 410 to drive the transmission frame 738 to move downward. When some workpieces 900 which are difficult to cut are processed and the radius is increased, the connecting assembly 800 with small downward movement is selected, so that the rotating speed of the workpieces 900 is reduced, but the reduction is small, and the quality of the cut can be ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
