Specifically, the adjustable vertical slotting machine is configured in a split structure with three components, a workbench 1, an upper fixed assembly 5, and a lower fixed assembly 6. By driving the symmetrical threaded seat with a bidirectional screw, the fixed rod is synchronized to move centripetally, automatically correcting the workpiece position so that the center point of the workpiece is located directly below the slotting knife, avoiding the deviation or deformation caused by unilateral clamping, improving the clamping accuracy and stability. The upper and lower fixed assemblies are designed to be linked, automatically synchronizing the position of the upper fixed assembly when adjusting the lower fixed assembly, reducing the manual adjustment steps, and reducing the adjustment time of the fixed assembly when the workpiece is alternately slotted.

[0034] The upper end of the workbench 1 is fixed with a slotting knife 3, and the upper end surface of the workbench 1 is symmetrically provided with at least one limiting groove 102 about the vertical center line of the slotting knife 3. The upper end surface of the workbench 1 is fixed with a lower fixed assembly 6;

[0035] The lower fixed assembly 6 includes a screw 61, a fixed rod 62, a threaded seat 63, and a connecting rod 64. The inner side of each of the plurality of limiting grooves 102 is slidably provided with a fixed rod 62. The upper end of each of the plurality of fixed rods 62 is fixed with a threaded seat 63. The inner side of the threaded seat 63 is threadedly connected with a screw 61. The side of the threaded seat 63 close to the slotting knife 3 is fixed with a connecting rod 64. The two sides of the slotting knife 3 are symmetrically provided with an upper fixed assembly 5, and the bottom end of the upper fixed assembly 5 is rotatably connected with the lower fixed assembly 6.

[0036] When in use, if the center of the workpiece is slotted, the workpiece needs to be fixed directly below the slotting cutter 3, and the fixed rod 62 is pulled out when the workpiece of different sizes is moved to the position directly below the slotting cutter 3, and when the workpiece is moved between the two fixed rods 62, the screw rod 61 is rotated, the two ends of the screw rod 61 are respectively provided with left-handed threads and right-handed threads, and the outer sides of the left-handed threads and the right-handed threads are in threaded connection with the threaded seats 63, so that when the screw rod 61 is rotated, the two threaded seats 63 are synchronously moved inward, and then the two fixed rods 62 are moved to the side close to the workpiece, and the workpiece is fixed, and the two fixed rods 62 are symmetrically arranged about the slotting cutter 3, so that the workpiece is pushed to the work position to be slotted during the movement of the fixed rod 62, so as to correct the position of the workpiece, and the symmetry can make the slotting cutter 3 accurately align the center of the workpiece, thereby further reducing the adjustment time, and the synchronization can improve the clamping accuracy and stability of the workpiece, and can avoid the deformation or position deviation of the workpiece caused by unilateral clamping, and when clamping workpieces of different lengths, only the position of the fixed rod 62 needs to be changed by rotating the screw rod 61, so that the workpiece of different sizes can be adapted, thereby reducing the adjustment time and improving the practicability of the device.

[0037] Then, when slotting, the slotting cutter 3 moves vertically downward, and before the slotting cutter 3 contacts the workpiece, the upper fixing assembly 5 contacts the workpiece first and provides downward pressure to fix the workpiece, thereby further improving the stability of the workpiece during slotting, and the threaded seat 63 is fixed with a connecting rod 64 between the upper fixing assembly 5, so that when the length of the workpiece is reduced, the distance between the two threaded seats 63 is reduced, and the upper fixing assembly 5 is adapted to the length of the workpiece by the connecting rod 64, thereby further saving the time of adjusting the upper fixing assembly 5.
