Abstract
The invention discloses a homemade pin shaft which comprises a pin head and a pin body. The pin body is vertically arranged on the pin head. Both the pin head and the pin body are cylindrical and are coaxial. The top of the pin body is provided with a semi-ring-shape gap. The semi-ring-shape gap is internally provided with a first semicircular protruding block in a protruding mode. The axis of the first semicircular protruding block is coaxial with the pin body. The peripheral face, opposite to the first semicircular protruding block, of the pin body is provided with a second semicircular protruding block, and the second semicircular protruding block is opposite to the first semicircular protruding block. The homemade pin shaft is provided with the semicircular protruding blocks, the required rotating and connection functions are achieved, and matched parts can be limited and positioned as well.
Description
Technical field
The present invention relates to a kind of self-control bearing pin.
Background technique
With self-control bearing pin part, originally porose parts can be connected in some machinery.In some cases except require shank have rotate except being connected, also want that to coordinate part spacing and location, needs design especially.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of self-control bearing pin, and this self-control bearing pin is provided with semicircle projection, except requiring to have except rotation and connection function, can also carry out spacing and location to the part coordinated.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of self-control bearing pin, comprise: plunger and shank, described shank is vertically set in described plunger, described plunger and shank are cylindrical body, described plunger and shank coaxial, the top of described shank is provided with a semi-circular breach, one first semicircle projection is extruded with in described semi-circular breach, the axis of described first semicircle projection is coaxial with described shank, side face relative with described first semicircle projection on described shank is provided with the second semicircle projection, described second semicircle projection is relative with described first semicircle projection and establish.
In a preferred embodiment of the present invention, the top of described first semicircle projection is projection end face, and described projection end face exceeds the end face of described second semicircle projection.
In a preferred embodiment of the present invention, the top end face of described shank is provided with a circular hole.
In a preferred embodiment of the present invention, the outer circumferential face of described plunger is processed with a milling flat, the axis being parallel of described milling flat and described shank.
The invention has the beneficial effects as follows: the present invention makes bearing pin by oneself and is provided with semicircle projection, except requiring to have except rotation and connection function, spacing and location can also be carried out to the part coordinated.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of self-control bearing pin of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, plunger, and 2, shank, 3, semi-circular breach, the 4, first semicircle projection, 5, projection end face, 6, circular hole, the 7, second semicircle projection, 8, milling flat.
