Problems solved by technology

[0002] In the prior art, there is a CNC turret punch press driven by a Y-axis single screw rod, which includes a beam on which a nut seat is arranged, and a screw rod is fixed on the machine body through a bearing, and the screw rod is matched with the nut seat. The screw rod is connected with the fixed motor on the fuselage. There is only one set of screw rod and nut, which are either installed on the side of the fuselage or in the middle of the fuselage. When they are installed on the side of the fuselage, it is easy to cause unbalanced load; Installed in the middle of the fuselage, when the clamp is offset from the center, the machining accuracy will be affected due to the force deviated from the axis

Abstract

The present invention discloses one kind of numerically controlled capstan punch with double screw driven Y-axle and belongs to the field of numerically controlled punch technology. The numerically controlled capstan punch includes cross beam, screw nut seats on the cross beam, lead screws fixed via bearing on the frame and matched to the screw nuts, motor on the frame. There are two screw nut seats set on two sides of the cross beam, tow lead screws set in parallel, and one motor with shaft connected to the lead screws via the sync belt wheels and belts. The rotating motor drives two lead screws synchronously to drive the screw nut seats and the cross beam to translate in Y-direction. The synchronous motion of two lead screws makes the cross beam possess balanced stress without offset, smooth conveyance and good dynamic feeding characteristic and lead to high machining precision of the machine tool.

Description

technical field [0001] The invention relates to a numerically controlled machine tool, in particular to a numerically controlled turret punching machine. Background technique [0002] In the prior art, there is a CNC turret punch press driven by a Y-axis single screw rod, which includes a beam on which a nut seat is arranged, and a screw rod is fixed on the machine body through a bearing, and the screw rod is matched with the nut seat. The screw rod is connected with the fixed motor on the fuselage. There is only one set of screw rod and nut, which are either installed on the side of the fuselage or in the middle of the fuselage. When they are installed on the side of the fuselage, it is easy to cause partial load and stress; Installed in the middle of the fuselage, when the clamp is offset from the center, the machining accuracy will be affected due to the deviation of the force from the axis. Contents of the invention [0003] The object of the present invention is to p...
