Abstract

The invention discloses a high-precision positioning pin knock-in mechanism, which is used for knocking a positioning pin (9) into a workpiece (1). The workpiece (1) is provided with a recessed part (10), and the recessed part (10) includes a bottom surface (11 ) and the side wall (12), the bottom surface (11) is provided with a plurality of pin holes (2), and the high-precision positioning pin knock-in mechanism includes a body (3), a punch (4) and a positioning piece (7), which are independent of each other. The body (3) is provided with a guide hole (5) communicating with the pin hole (2), the punch (4) is installed in the guide hole (5), and the body (3) is provided with a positioning part (13), the positioning piece (7) is arranged between the body (3) and the bottom surface (11), and the positioning piece (7) and the positioning portion (13) fix the relative position of the body (3) and the workpiece (1). By positioning the body and the workpiece, the present invention aligns the guide hole with the pin hole, solves the problem of inconvenient installation of the positioning pin in the recessed part, and has high installation accuracy.

Description

technical field [0001] The invention relates to a high-precision positioning pin knock-in mechanism. Background technique [0002] When the body is connected by multiple parts, and each part needs to maintain a precise position during processing and assembly, positioning pins should be used for positioning. Locating pins are often used in machining and assembly, but some workpieces have complicated shapes, so that the locating pins need to be installed in recessed parts. At this time, manual operation is inconvenient and installation is difficult. Contents of the invention [0003] The object of the present invention is to address the above-mentioned defects in the prior art, and provide a high-precision positioning pin knocking mechanism, so that the positioning pins recessed into the workpiece can be easily installed. [0004] In order to realize the above-mentioned purpose of the invention, the present invention has adopted following technical scheme: [0005] A high-...
