Problems solved by technology

[0004] However, in the above-mentioned overturning fixture, when the workpiece is initially clamped, that is, when the workpiece is placed on the overturning base but the pressing mechanism is not pressed, the workpiece is in an unpositioned state. At this time, the workpiece is prone to movement, causing the pressing mechanism to The workpiece is not positioned and pressed against the set position

Abstract

The invention aims at providing a turnover positioning fixture in order to conduct pre-positioning on a workpiece on the premise of not affecting normal machining of the workpiece. The turnover positioning fixture comprises a base and a turnover pedestal rotatably arranged on the base around the horizontal axis. The turnover pedestal is provided with a carrying position for carrying the workpiece.The turnover pedestal is further provided with a pressing mechanism for pressing the workpiece. An end part positioning part is detachably or retractably assembled in the position, located beside thecarrying position, of the turnover pedestal. The end part positioning part is provided with a stop position used for being in stop fit with a to-be-machined surface of the workpiece so as to make thepressing mechanism to press the workpiece and is further provided with a moving position for moving the to-be-machined surface of the workpiece. Through the turnover positioning fixture, the workpiece is pre-positioned on the premise of not affecting normal machining of the workpiece.

Description

technical field [0001] The invention relates to a flip positioning fixture. Background technique [0002] In the prior art, it is sometimes necessary to mill or drill multiple surfaces of the workpiece. At this time, it is necessary to arrange the corresponding surfaces of the workpiece upwards to facilitate processing. This requires turning the workpiece multiple times to complete the processing of the workpiece. [0003] A utility model patent with the authorized notification number CN206493139U discloses a flip tooling fixture, which includes a base and a flip base mounted on the base for horizontal rotation, and a pressing mechanism for pressing the workpiece is arranged on the flip base , the pressing mechanism includes a plurality of clamping parts, the clamping part includes a hydraulic cylinder fixed on the flip base, the top of the hydraulic cylinder is fixed with a pressure head, and the hydraulic cylinder can drive the pressure head to move up and down and around ...
