Description

Adjustable positioning pin Technical Field The utility model mainly relates to the field of positioning pins, in particular to an adjustable positioning pin. Background In the fields of machine manufacturing, assembly and automated production, locating pins are used as a basic and key locating element and are widely applied to the accurate locating and fixing between a workpiece and a die, a clamp or equipment. The key function of the pin body is that the pin body is matched with a reserved positioning hole on a workpiece, so that the degree of freedom is eliminated, and the relative position precision between parts in the processing and assembling processes is ensured. During the operation of the specific examples, the inventors have found the following drawbacks: however, positioning pins with different sizes are adopted at different positions, but when the positioning pins are not required to bear larger force, the diameter, the length and the mounting position of the pin body are preset, and dynamic adjustment cannot be carried out according to actual working conditions; For example, when workpieces with different apertures or position changes need to be adapted, an operator needs to frequently replace positioning pins with different specifications or reprocess positioning holes, which results in reduced production efficiency and increased cost, and positioning reference errors are easily accumulated in the repeated disassembly and assembly processes. The above-described contents are within the technical knowledge of the inventors, and the technical contents in the art are huge and complicated, and thus the above-described contents of the present application do not necessarily constitute the prior art. Disclosure of utility model 1. The utility model aims to solve the technical problems that: The utility model provides an adjustable positioning pin which is used for solving the technical problems in the background technology. 2. The technical scheme is as follows: in order to achieve the purpose, the technical scheme provided by the utility model is that the adjustable positioning pin comprises a pin body structure, wherein an adjustable structure is arranged in the pin body structure; The pin body structure comprises a pin body, wherein a connecting hole is formed in the middle of the inner part of the pin body, and a thread groove is formed in the top of the connecting hole; The adjustable structure comprises an adjustable pin body and a rotating shaft, wherein a positioning tube is arranged at the top of the adjustable pin body and is slidably connected with the inner wall of the connecting hole. Further, the inside of the pin body is provided with a guide hole, the bottom of the guide hole is provided with a slot, the outer wall of the pin body is provided with a laminating ring, and the outer wall of the pin body is provided with a first lower water tank. Further, the number of the first downcomers is set to be a plurality of, and the plurality of the first downcomers are annularly arranged on the outer wall of the pin body. Further, the top of the adjustable pin body is provided with a sliding shaft, the top of the sliding shaft is provided with a sliding block, the sliding block is connected inside the guide hole in a sliding mode, and the bottom of the adjustable pin body is provided with a positioning groove. Further, the top of rotation axis is provided with the screw thread dish, the screw thread dish is connected with the screw thread groove continuously, the bottom of rotation axis is provided with the bottom plate, the outside at bottom plate top is provided with the side ring, side ring and constant head tank sliding connection. 3. The beneficial effects are that: Compared with the prior art, the technical scheme provided by the utility model has the following beneficial effects: According to the utility model, the length of the locating pin can be increased to adjust the locating pin through the arranged adjustable pin body capable of sliding downwards, meanwhile, the locating ring and the sliding shaft are also arranged between the adjustable pin body and the pin body and are used for increasing the connection strength between the adjustable pin body and the pin body, the position of the adjustable pin body can be adjusted through the arranged rotating shaft, and the adjustable pin body is fixed through the mutual matching of the thread groove and the thread disc, so that the change of the size of the locating pin is avoided.
