Abstract
A kind of expansion can clamping and positioning pin, and it relates to Manufacturing Technology for Automotive Parts field.It comprises stub and secondary pin, is threaded connection, uniform four opening slots of stub cylindrical between described stub and secondary pin, the upper reserved interior hexagonal being used for clamping of secondary pin.The utility model eliminates free gap, serves the effect of product stationary positioned.
Description
Technical field
The utility model relates to Manufacturing Technology for Automotive Parts field, and being specifically related to a kind of expansion can clamping and positioning pin.
Background technique
Automotive-type punching press component part and welding assembly are in postorder machining, straight pin or taper pin is all often adopted to position, for turning over the product such as hole type parts or the welding assembly containing sleeve pipe, often because hole flanging dimensional accuracy lower grade or the internal diameter of sleeve pipe exists not round defect, easily cause when adopting straight pin location, there is the situation that free gap or pin can not insert; And taper pin is inapplicable with cover pipe part for hole flanging.
Model utility content
The purpose of this utility model is to provide a kind of expansion can clamping and positioning pin, it is made up of stub and the large main body of secondary pin two, the pair pin of expansion pin is moved downward by screw-thread fit, when the conical surface of pair pin and the contact of incline plane of slide block and while continuing to move downward, slide block starts outwards to move along the slide block slot of stub, when pair pin moves to dead point, expansion pin reaches greatest diametrical dimension.
In order to solve the problem existing for background technique, the utility model is by the following technical solutions: it comprises stub 1 and secondary pin 2, be threaded connection between described stub 1 and secondary pin 2, uniform four opening slots of stub cylindrical, secondary pin continued to employ in advance the interior hexagonal for clamping.
The utility model expansion can the work of clamping and positioning pin time, the screw thread on revolute pin, while secondary pin moves downward, slide block radially moves, and expansion pin starts " expansion ", until the inner side of shoe contact workpiece flange or sleeve pipe, continue revolute pin screw thread, until tighten.Now workpiece is inflated pin and expands fixing, and workpiece is difficult to be moved or rotate, and eliminates free gap, serves the effect of product stationary positioned.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises stub 1 and secondary pin 2, is threaded connection between described stub 1 and secondary pin 2, uniform four opening slots of stub cylindrical, secondary pin is continued to employ in advance the interior hexagonal for clamping.
The utility model expansion can clamping and positioning pin, and while secondary pin moves downward, slide block radially moves, and expansion pin starts " expansions ", until the inner side of shoe contact workpiece flange or sleeve pipe, continuation revolute pin screw thread, until tighten.Now workpiece is inflated pin and expands fixing, and workpiece is difficult to be moved or rotate, and eliminates free gap, serves the effect of product stationary positioned.
