Abstract
The utility model relates to an elliptical hole inner expansion centering device, which comprises a housing, a top bar, a spring thimble, and a cylinder, wherein a vertical pore passage is equipped in the center of the housing bottom, the upper portion of the top bar is inserted into the vertical pore passage, the lower portion of the top bar is connected with the cylinder, the head of the top bar and the end of the spring thimble are both cone shaped, characterized in that the side face of the housing is provided with four horizontal pore passages in central symmetry which are communicated with the vertical pore passages, a spring thimble is arranged in each horizontal pore passage, and the end of the spring thimble contacts with the head of the top bar. Four symmetrical vertexes of the spring thimble can rightly confirm the right theoretical positions of the centre of the elliptical hole, and the vertexes position the elliptical hole when knocking out from the side hole of the housing, thereby realizing the clamping function. The utility model has the advantages of simple structure, easy manufacture, and prominent practicality.
Description
Technical field
The utility model relates to a kind of parts processing and uses positioner, specifically is a kind of elliptical aperture internal expanding centring means.
Background technology
Some auto parts and components often have elliptical aperture, and elliptical aperture will can be realized the processing in other face and hole as the location benchmark after the clamping to be positioned when this class part of processing.And at present, the public standard centring means that is used for the workpiece hole location mainly is a circular hole internal expanding centring means.The design feature of this device mainly comprises three horizontal spring thimbles that place in the housing and be mutually 120 ° of angles, and head and the terminal vertical push rod that contacts of three horizontal spring thimbles; Be taper because the horizontal spring thimble is terminal with vertical push rod head, so when push rod was made progress jack-up by air cylinder driven, three horizontal spring thimbles ejected in the housing side opening simultaneously, the theoretical tram in the circular hole center of circle has been determined on their summit just; Therefore can be good at circular hole is positioned and clamps.Yet for elliptical aperture, the theoretical tram in the oval center of circle obviously can't be determined in the summit of three horizontal spring thimbles, so the function that this class circular hole internal expanding centring means location clamps just can't be accomplished.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of elliptical aperture internal expanding centring means, reaches realization to elliptical aperture location on the auto parts and components and the purpose that clamps, and is convenient further to the processing in other face of this type component, hole.
The main technical schemes that the utility model is used to solve the problems of the technologies described above is: a kind of elliptical aperture internal expanding centring means, mainly comprise housing, push rod, spring thimble and cylinder, the housing bottom center is equipped with vertical channel, and insert in the vertical channel on push rod top, and the bottom connects cylinder; Push rod head and spring thimble end are taper; It is characterized in that the housing side is equipped with four horizontal holes that are communicated with and are centrosymmetric with vertical channel; Each horizontal hole is built-in with spring thimble, and spring thimble is terminal to be contacted with the push rod head.
The utility model mainly is on the basis of existing circular hole internal expanding centring means, the improvement that its partial structurtes are carried out; By increasing a spring thimble, adjust the relative position between spring thimble simultaneously, make the architectural feature of internal expanding centring means become " four at claiming " from original " three at claiming ".Because the summit of the spring thimble of four symmetries can be determined the theoretical tram in the elliptical aperture center of circle just, when they ejected in the housing side opening like this, to the elliptical aperture location, the function of clamping had just obtained good realization.Whole apparatus structure is simple, easily processing, and practicality is outstanding.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further, as shown in Figure 2, its structure comprises housing 1, push rod 2, spring thimble and cylinder 3, housing 1 bottom centre is equipped with vertical channel, insert in the vertical channel on push rod 2 tops, and the bottom connects cylinder 3, and its head is taper.Housing 1 side is equipped with four horizontal holes (Fig. 1 can react this feature) that are communicated with and are centrosymmetric with vertical channel; Each horizontal hole is built-in with spring thimble.
The same with prior art, spring thimble specifically is made of small core shaft 4, spring 5 and the tape spool adjustment screw 6 to through hole.The lateral aperture road junction is milled with internal thread, and adjustment screw 6 is screwed in the horizontal hole.Small core shaft 4 is the thickness connecting rod, forms step surface between the thickness bar.Anterior thin bar passes the axially extending bore of adjustment screw 6, and the end of the thick bar in rear portion is taper, and contacts with the head of push rod 2.Be with spring 5 on the thin bar between the inner face of adjustment screw 6 and step surface.
During use, when cylinder 3 drives upwards jack-up of push rod 2, the anterior thin bar of four small core shafts 4 that are symmetrically distributed ejects in the housing side opening simultaneously, with entire mechanism tensioner (dynamics of certain tensioner in the workpiece elliptical aperture, can be screwed into the degree of depth in the horizontal hole by control and regulation screw 6, promptly the size of control spring 5 pretightning forces is regulated).Because the theoretical tram at elliptical aperture center has been determined on the summit of four small core shafts 4 just, so well realized clamping and location to elliptical aperture.
