Abstract

The invention discloses a connecting rod positioning mechanism. The mechanism comprises an assembly flange, a positioning shaft and a connecting rod mechanism, wherein the connecting rod mechanism comprises a movable rod, a connecting rod and a fixed shaft; two ends of the connecting rod are connected with one end of the positioning shaft and the front end of the movable rod by pins respectively; the top of the movable rod is connected through the fixed shaft; and the other end of the positioning shaft is opposite to the assembly flange. The connecting rod positioning mechanism has the advantages that front and back motion of the positioning shaft is implemented through a connecting rod transmission principle, the workpiece can be positioned accurately, shaft penetration and die stripping save power, and the operation and assembly are convenient. The positioning shaft can be detached and changed into different lengths and diameters according to actual requirement, so positioning of workpieces in different sizes can be implemented, and the application range is wide.

Description

technical field [0001] The invention relates to a positioning mechanism, in particular to a positioning mechanism for positioning a workpiece by using the transmission principle of a connecting rod. Background technique [0002] At present, when assembling workpieces such as steel structural parts, if some holes have size requirements, the holes need to be positioned. The usual method is to use the shaft to directly pass through the holes for positioning. The problem of this positioning method is: when positioning the workpiece, it takes time to locate the shaft, and it is difficult to take out the shaft when the mold is lifted after assembly, and the accuracy of the shaft will be damaged if it is knocked out with a hammer; and for some blind hole structures or stepped hole structures , the shaft cannot pass through the workpiece for positioning or the shaft cannot be taken out when the mold is ejected after positioning with the shaft. Contents of the invention [0003] P...
