Problems solved by technology

[0004] ①. The ball screw is a slender shaft with poor rigidity, and there is vibration during operation. When running at high speed, the vibration is more severe, which seriously affects the transmission accuracy. Especially the X-axis travel is long, and the required ball screw is also Longer, lower rigidity, and lower rotational speed, which seriously restricts the increase of feeding speed
[0005] ②. The Y-axis ball screw nut

Embodiment Construction

[0020] Such as Figure 1-4 Shown is a high-speed feeding mechanism, including a feeding table 11 set on the frame, the feeding table 11 is provided with a Y-axis drive mechanism, the upper side of the Y-axis drive mechanism is connected with a beam 4, and the beam 4 is connected with X Shaft driving mechanism, the longitudinal direction of the beam 4 is perpendicular to the Y axis and parallel to the X axis.

[0021] The structure of the Y-axis drive mechanism: It includes two Y-axis linear guides 12 arranged in parallel on the front and rear sides of the feeding table 11. The Y-axis linear guide 12 is matched with a Y-axis slider 9, and the Y-axis slider 9 is connected with Connecting plate 8; the bottom of the cross beam 4 is connected and fixed with the two connecting plates 8 by the reinforcing plate 7. The front and rear sides of the reinforcing plate 7 are provided with reinforcing ribs 18 connected to the cross beam 4; the front and rear edges of the feeding table 11 are r...

Abstract

The invention relates to a high-speed feeding mechanism belonging to the field of press machines, and comprising a feeding workbench arranged on a stand, wherein a Y-axis driving mechanism is arranged on the feeding workbench; the upper side of the Y-axis driving mechanism is connected with a beam; the beam is connected with an X-axis driving mechanism; the length direction of the beam is vertical to the Y axis and parallel to the X axis; the Y-axis driving mechanism is a driving mechanism with double servo motors and double lead screws; and the X-axis driving mechanism is a gear rack transmission mechanism. The high-speed feeding mechanism can reduce the vibration of the whole device and ensure smooth running of the device. Matched with a weight reduction design of the beam, the whole feeding mechanism is light in weight, thus ensuring high-speed, accurate and smooth feeding. The high-speed feeding mechanism provided by the invention can feed materials at high speed smoothly, obviously improves the work efficiency, and can be used on a numerical control turret punch press.

Description

Technical field [0001] The invention relates to a press, in particular to a feeding mechanism on a numerical control turret punch press. Background technique [0002] The feeding axis of the CNC turret punch press includes the X axis in the left and right movement direction of the carriage and the Y axis in the front and back movement direction of the beam; its structure mainly includes the X-axis transmission mechanism, the Y-axis transmission mechanism and the beam. At present, the two feeding shafts of CNC turret punch presses generally adopt a direct drive structure with a single servo motor and a single ball screw; among them, the X axis: the ball screw is installed on the beam, and the beam is also equipped with linear guides and carriage installation On the linear guide slider, guided by a linear guide, the carriage is rigidly connected with the ball screw nut through a connecting piece; the servo motor rotates forwards and backwards to drag the carriage to reciprocate lin...
