The invention provides a positioning pin capable of adjusting a diameter. The positioning pin comprises a pin body, a shaft sleeve, at least two sleeve bodies and an elastically annular body, wherein the pin body comprises a screw cap and a main shaft which are integrally formed; the main shaft comprises an external thread part and a pressing part; an external thread is formed on the external thread part; the shaft sleeve is sleeved on the external thread part of the main shaft of the pin body; a penetrating sleeving hole is formed in the shaft sleeve; an internal thread matched with the external thread of the external thread part is formed in the sleeving hole; at least two clamping blocks are arranged on the shaft sleeve; the at least sleeve bodies are clamped at the peripheries of the pin body and the shaft sleeve; each sleeve body is provided with a clamping opening matched with each clamping block of the shaft sleeve; and a shaft sleeve accommodating part and a pressing surface are arranged in each sleeve body. The positioning pin capable of adjusting the diameter is very convenient to assemble and disassemble; furthermore, the positioning pin capable of adjusting the diameter of each specification meets a requirement on compact matched connection of all part pin holes within a certain diameter range.
Description
technical field [0001] The present invention relates to a connection fastener, and in particular to a positioning pin with adjustable diameter. Background technique [0002] At present, as a common connecting fastener, positioning pins are widely used in various fields of mechanical manufacturing. [0003] Usually, positioning pins are used to connect two or more parts with holes to play the role of "centering" and "positioning". The positioning pin is usually fixed in the hole by a small amount of interference, so the size, shape and surface roughness of the part pin hole are highly required, and the diameter of the positioning pin is required to be slightly larger than the diameter of the part pin hole. Certain tools are used during installation Knock dowel pins into component pin holes. However, in some cases, the positioning pin needs to be disassembled frequently, which constitutes a pair of contradictions. Due to the tight fit between the positioning pin and the pin ...
