Description

Pre-compression positioning pin gasket Technical Field The utility model relates to the technical field of positioning pin gaskets, in particular to a pre-compression positioning pin gasket. Background In the field of mechanical manufacture and assembly, the locating pin is a key element for ensuring the relative position precision of parts, the locating effect directly influences the overall performance and the operation stability of equipment, the locating pin is generally cylindrical, part of the locating pin is provided with taper, and medium carbon steel or alloy steel is adopted as the material for ensuring the strength and the wear resistance. The locating pin has some problems in the in-service use, on the one hand, when ordinary locating pin is installed, only rely on self and pinhole's cooperation to fix a position, receive external force such as vibration, impact to act on, appear not hard up phenomenon easily, lead to the relative position between the spare part to change, influence the normal operating of equipment, another convenience, in the assembly process, there is certain clearance probably between locating pin and the pinhole, this accuracy and the stability that also can reduce the location. Disclosure of utility model The present utility model has been made in view of the above-described problems with the conventional positioning pins. Therefore, the utility model aims to provide the pre-compression positioning pin gasket, which solves the problems that the positioning pin is positioned only by the cooperation of the positioning pin and the pin hole when being installed, the loosening phenomenon is easy to occur under the action of external forces such as vibration, impact and the like, and a certain gap possibly exists between the positioning pin and the pin hole in the assembly process, so that the positioning accuracy and stability are reduced. In order to achieve the above object, the present utility model provides the following technical solutions: The utility model provides a precompaction locating pin gasket, includes the locating pin body, the gasket has been cup jointed to the surface of locating pin body, the surface of gasket is provided with annular arch, annular bellied surface encircles a plurality of first elasticity compact heap of fixedly connected with, the inside of gasket is provided with stop gear, locating pin body and stop gear assorted, the inner wall symmetry fixedly connected with a plurality of second elasticity compact heap of gasket, every second elasticity compact heap is laminated with the locating pin body. Preferably, the limiting mechanism comprises two limiting blocks, the two limiting blocks are symmetrically and fixedly connected to the inner wall of the gasket, two limiting grooves are symmetrically formed in the outer surface of the locating pin body, and the two limiting blocks are respectively and slidably arranged in the corresponding limiting grooves. Preferably, each of the first elastic pressing blocks and each of the second elastic pressing blocks is hemispherical. Preferably, the cross section of the annular protrusion is trapezoid. Preferably, the outer surface of the locating pin body is symmetrically provided with two planes, and the two planes are respectively matched with the corresponding second elastic compression blocks.
