Detailed Description
The invention is further described below with reference to the accompanying drawings:
the embodiment provides a rotatory elevating system for cutter production, as shown in fig. 1, including mounting bracket 1, ball, drive assembly 4 and actuating mechanism, ball includes ball 2 and ball 3 with ball 2 matched with, and ball 3 is fixed to be located mounting bracket 1 and the cover locates ball 2, and the tip of ball 2 is connected with the cutting mechanism who processes the cutter.
In this embodiment, the ball nut 3 includes the first nut 31 and the second nut 32, the first nut 31 is fixed to the front end of the mounting bracket 1, the second nut 32 is fixed to the rear end of the mounting bracket 1, and the driving mechanism and the transmission assembly 4 are both located between the first nut 31 and the second nut 32, so as to improve the stability of the ball screw 2 during the up-and-down rotation. In order to avoid ball screw 2 and ball nut 3 breaking away from, lifting means reliability, ball screw 2's both ends all are equipped with stopper 21.
Referring to fig. 2, 3 and 4, the transmission assembly 4 includes a pushing plate 41, a roller 42 and two supporting plates 43 parallel to each other, the supporting plates 43 are fixed in the middle of the ball screw 2 and perpendicular to the ball screw 2, the pushing plate 41 is sleeved on the ball screw 2 (the pushing plate 41 is provided with a relief through hole 45, the pushing plate 41 and the ball screw 2 are not contacted all the time), the pushing plate 41 is provided with a roller shaft 44 parallel to the supporting plates 43, the roller 42 is sleeved on the roller shaft 44 and located between the two supporting plates 43, and the roller 42 can rotate around the central axis of the roller shaft 44 under the action of external force. The roller 42 is usually made of a hard material such as stainless steel, and hardly deforms when being extruded, thereby facilitating accurate control of the position of the actuating mechanism
