Straightening auxiliary device

Abstract

The invention discloses a straightening auxiliary device which comprises ejector pin mechanisms which are fixed to the two sides of a machine body stand column respectively and used for clamping a workpiece, and a V-shaped supporting and floating mechanism which is matched with the ejector pin mechanisms and used for supporting the workpiece. The V-shaped supporting and floating mechanism comprises a V-shaped supporting base, a floating supporting base arranged on the back of the V-shaped supporting base and used for supporting the workpiece together with the V-shaped supporting base, a servomotor in drive connection with the V-shaped supporting base, and a ball screw assembly. The servo motor drives the V-shaped supporting base and the floating supporting base to do horizontal reciprocating motion in the axial direction of the workpiece through the ball screw assembly. According to the straightening auxiliary device provided by the invention, a servo speed reducer and the ball screware adopted for transmission, so that left-right movement of the V-shaped supporting and floating mechanism is achieved; a left ejector pin and a right ejector pin are pneumatically driven, so that workpiece clamping and positioning functions of the ejector pin mechanisms are achieved; and lifting adjustment can be conducted on the ejector pin mechanisms according to needs, so that the straightening speed and precision of a pressing machine and the convenience of product replacement are improved.

Description

technical field [0001] The invention relates to the field of hydraulic press equipment, in particular to a straightening auxiliary device. Background technique [0002] Shaft workpieces are widely used in various fields of industry, and they need to be processed before they are put into use. Since the machining and production of shaft parts has been generally mechanized, the requirements for positioning and supporting and fixing shafts before processing are also increasing. higher. The existing alignment auxiliary mechanism usually uses a screw rod to manually adjust the support position, and the positioning is performed by a manual handle, which has low precision, slow speed, troublesome replacement of varieties, and high labor costs. Can not meet the high precision and high efficiency of the press and the requirements of changing varieties. Contents of the invention [0003] The object of the present invention is to propose a straightening auxiliary device in order to ...
