Abstract

The invention relates to a turret punch press, in particular to a main transmission system of a full-electric servo ball screw-typed numerical control turret punch press. According to the technical proposal which is provided by the invention, the output shaft of the servo motor is connected with a rolling ball leading screw which is matched and connected with a nut which is pivotally connected with a long connecting rod; the other end of the long connecting rod is pivotally connected with a forcing block by utilizing a pin roll. The forcing block is arranged on a core shaft; the other end of the forcing block is pivotally connected with a short connecting rod by utilizing a pin. A triangle is formed among the center of the pin roll, the center of the pin and the axle center of the core shaft; furthermore, the distance between the axle center of the core shaft and the center of the pin is less than the distance between the center of the pin roll and the axle center of the core shaft; the other end of the short connecting rod is pivotally connected with a sliding block and the other end of the sliding block is provided with a striking head; the middle part of the sliding block is provided with a guide sleeve which can guide the sliding block; the nut is provided with a guide rail which can guide the nut. The turret punch press can effectively simplify the structure and reduce energy consumption.

Description

technical field [0001] The invention relates to a turret punch press, in particular to a main drive system of an all-electric servo ball screw type numerical control turret punch press. Background technique [0002] In the prior art, the main transmission system of the all-electric servo ball screw type CNC turret punch press generally adopts a toggle mechanism, which is usually composed of a servo motor and a reduction mechanism, as well as a crank rod, a connecting rod 1, a transition rod, a swing rod, and a connecting rod. Composition of rod II and slide block etc. The main shortcoming of this mechanism is: 1, because there is gap in the speed reducer in this main transmission mechanism, can influence the accurate location of hole point under the slide block of punching press. 2. This mechanism is relatively complicated, which reduces the mechanical efficiency. Contents of the invention [0003] The purpose of the present invention is to design a main drive system of ...
