Abstract
The invention discloses a positioning block with oblique planes. The positioning block comprises a positioning block body, wherein one or more oblique planes are processed on the side of the positioning block body; the oblique planes extend from the side of the positioning block body to the top surface of the positioning block body; and a bolt is arranged on the bottom surface of the positioning block body and used for fixing the positioning block body on a machine tool. According to the positioning block, cuttings are not easy to pile on a positioning surface; and the cuttings can be rapidly removed through air blow holes.
Description
Technical field
The present invention relates to the parts of machine-building manufacture field, particularly a kind of locating piece for locating.
Background technology
In machine-building, extensive use plane, as positioning datum, as class parts such as casing, support, supports, in its main manufacturing procedure, often adopts plane positioning, and so just the normal locating piece that adopts is as setting element.General locating piece is all on locating piece body, to be processed with countersunk head to cross nail hole, for locating piece being fixed on to lathe with bolt.In production practices, applicant's discovery, this type of locating piece is easily piled up smear metal on sunk screw place and locating surface, has a strong impact on positioning precision and even causes part to be scrapped.
Therefore, be badly in need of a kind of novel locating piece, it can make smear metal be not easy pile up and can make smear metal be able to quick removing.
Summary of the invention
The object of the invention is to overcome defect in above-mentioned prior art, by inclined-plane is set on locating piece, avoid the deposition of smear metal on the locating surface of locating piece.
Further, the object of the invention is to remove fast smear metal by gas hole is set.
For achieving the above object, the invention provides a kind of bevelled locating piece of being with, wherein said locating piece comprises locating piece body, place, side at this locating piece body is processed with one or more inclined-planes, described inclined-plane extends to the end face of described locating piece body from the side of locating piece body, and described locating piece body is provided with bolt at its place, bottom surface, for this locating piece body is fixed on lathe.
In technique scheme, the end face of locating piece body is provided with gas hole, and the side of this locating piece body is provided with for connecting the connecting screw hole of tracheae, and described gas hole is connected with described connecting screw hole.
In technique scheme, described tracheae matches with connecting screw hole by connector.
In technique scheme, described gas hole is arranged at the center of the end face of described locating piece body.
In technique scheme, the diameter of described gas hole is between 0.8mm and 1mm.
In technique scheme, described inclined-plane is linear slope or the inclined-plane with flexibility.
Compared with prior art, the present invention has following beneficial effect: owing to having cancelled the countersunk head of locating piece, cross nail hole, and on locating piece, be processed with one or more inclined-planes, make just difficult accumulation smear metal on locating surface, and compressed air blows out from gas hole by tracheae, can effectively blow off locating surface and the smear metal of workpiece contact-making surface, thereby reach the object that improves positioning precision.

Main description of reference numerals:
1-locating piece body, 2-inclined-plane, 3-gas hole, 4-connecting screw hole, 5-connector, 7-tracheae, 10-locating piece.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of the specific embodiment.
As shown in Figures 1 to 4, it has shown according to the structure of the locating piece 10 of the specific embodiment of the invention.On locating piece body 1, be processed with one or more inclined-planes 2, thereby reduce the area of locating surface, wherein said inclined-plane 2 extends to the end face of described locating piece body from the side of locating piece body 1.Wherein, described one or more inclined-plane 2 can or have the inclined-plane of certain flexibility for linear slope.
At locating piece body, 1 bottom center place is provided with bolt 6, and it is for being fixed on lathe by locating piece 10; In the end face center of locating piece body 1, process a gas hole 3 again, compressed air blows out from gas hole 3, for blowing off locating surface and the smear metal of workpiece contact-making surface.Owing to having cancelled the countersunk head of locating piece, cross nail hole, and on locating piece body 1, processed inclined-plane 2, on locating surface, be just difficult for piling up smear metal, and compressed air has blown out from gas hole 3, can effectively blow off locating surface and the smear metal of workpiece contact-making surface, thereby reach the object that improves positioning precision.
Preferably, the diameter of gas hole 3 is between 0.8 millimeter to 1.0 millimeters, and this gas hole 3 can adopt the method processing of electric spark.
The place, side of locating piece body 1 is provided with the connecting screw hole 4 being connected with gas hole 3.One end of connector 5 is connected to connecting screw hole 4, and the other end is connected with tracheae 7, thereby makes compressed air to enter into locating piece body 1 by tracheae 7, and discharges from gas hole 3.
In the middle of practical operation, near lathe, provide compressed air source, for example gas compressor.Compressed air enters from tracheae 7, through connector 5 and connecting screw hole 4, blows out, for blowing off locating surface and the smear metal of workpiece contact-making surface from gas hole 3.Owing to having cancelled the countersunk head of locating piece, cross nail hole, and on locating piece, processed inclined-plane 2, on locating surface, be just difficult for piling up smear metal, and compressed air has blown out from gas hole 3, can effectively blow off locating surface and the smear metal of workpiece contact-making surface, thereby reach the object that improves positioning precision.
Disclosed is above only specific embodiments of the invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
