Abstract

The invention discloses a locating pin with adjustable diameter, and belongs to the technical field of positioning pins. The positioning pin comprises a guide section, a positioning section and a fixed section which are sequentially arranged from top to bottom, the central axes of the guide section, the positioning section and the fixed section are coincident, the guide section is locked in the manner that meshing of teeth between the guide section and the fixed section is singe-face meshing, and the diameter of the positioning section is adjusted in the manner that meshing of teeth of the positioning section and the guide section is double-face meshing. The locating pin is mainly used for enabling the freedom degree of parts in the X and Y directions to be zero, the positioning accuracy of the parts is improved, the product yield is improved, the positioning pin can meet the universality requirement to a certain degree, and meanwhile, disassembling and assembling are convenient.

Description

technical field [0001] The invention belongs to the technical field of positioning pins, and more specifically relates to a positioning pin with an adjustable diameter. Background technique [0002] With the rapid development of the home appliance industry, the precision requirements for home appliances are getting higher and higher. A large part of the parts on home appliances are realized by cold stamping dies, and the positioning accuracy directly affects the precision of stamping products. Therefore, for products The positioning requirements during the stamping process are particularly important. [0003] At present, in the actual stamping production process, positioning pins are basically used to position the plate, which plays the role of "centering" and "positioning". The degree of freedom in the direction is related to the processing accuracy of the locating pin, the pin hole of the part, and the mounting hole of the locating pin on the mold. There will be poor pos...
