Abstract
A kind of reference circle setting-out system, including fagging, lock-screw, paintbrush ruler, drawing needle, which is characterized in that be provided with horizontal through hole in the middle part of fagging, paintbrush ruler is inserted in horizontal through hole, and is fixed by lock-screw, and drawing needle is located at the end of paintbrush ruler；Be symmetrically arranged on the fagging of horizontal through hole two sides vertically to preceding screw hole and rear bolt hole, sliding bolt is threadedly coupled with rear bolt hole, and the bottom end of sliding bolt is equipped with ball bearing, before set bolt is inserted in screw hole, steel ball and spring are placed in set bolt inner cavity, hold-down bolt is connect with set bolt thread in inner cavity.Reference circle setting-out system of the invention, ingenious in design, structure is simple, easy to use, required reference circle can be accurately drawn on large-sized flange, and production cost is significantly less than existing large-scale compasses.
Description
Technical field
The present invention relates to machining ancillary equipment, especially a kind of reference circle setting-out system.
Background technique
Large-scale hollow flange must obtain before being attached hole drill hole machined by the reference circle position of each connecting hole on flange
It sets and is drawn on workpiece, generally use large-scale compasses in the prior art, this large size compasses are inconvenient to use, and price
Very _.
Summary of the invention
It is an object of the invention to provide a kind of large-sized flange reference circle line-plotting devices easy to use, production cost is low.
Reference circle setting-out system of the invention, including fagging, lock-screw, paintbrush ruler, drawing needle, which is characterized in that fagging
Middle part is provided with horizontal through hole, and paintbrush ruler is inserted in horizontal through hole, and is fixed by lock-screw, and drawing needle is located at the end of paintbrush ruler
Portion；Be symmetrically arranged on the fagging of horizontal through hole two sides vertically to preceding screw hole and rear bolt hole, sliding bolt is threadedly coupled with rear bolt hole,
The bottom end of sliding bolt is equipped with ball bearing and covers in bolt inner cavity before set bolt is inserted in screw hole and be placed with steel ball and spring, compresses
Bolt is connect with set bolt thread in inner cavity.
Reference circle setting-out system of the invention, in use, being calculated first according to the diameter of flange, indexing diameter of a circle
The length stretched out needed for paintbrush ruler；Paintbrush ruler is drawn out to required position, and is fixed with lock-screw；Hold-down bolt is adjusted, is made
The drawing needle of steel ball and paintbrush ruler end part in sliding bolt inner cavity is in same level, i.e., steel ball is placed in simultaneously with drawing needle syringe needle
The upper level-end face of flange；The position for adjusting sliding bolt, makes the ball bearing of its end against flange excircle；It is moved along flange excircle
Dynamic whole device, ball bearing are moved closely along flange excircle, and steel ball is moved along flange upper level-end face, and drawing needle is just horizontal on flange
End face draws reference circle.
Reference circle setting-out system of the invention, ingenious in design, structure is simple, easy to use, can be accurately in large-scale method
Required reference circle is drawn on orchid, and production cost is significantly less than existing large-scale compasses.Using this reference circle setting-out system production
Product, precision is higher, and the fitness of each part is higher, and the performance of product is stronger.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the lateral cut-away view of Fig. 1；
Fig. 3 bows for Fig. 1's to schematic diagram.
Specific embodiment
A kind of reference circle setting-out system, including fagging 1, lock-screw 6, paintbrush ruler 7, drawing needle 11, which is characterized in that fagging
1 middle part is provided with horizontal through hole, and paintbrush ruler 7 is inserted in horizontal through hole, and is fixed by lock-screw 6, and drawing needle 11 is located at paintbrush ruler 7
End；Be symmetrically arranged on the fagging 1 of horizontal through hole two sides vertically to preceding screw hole and rear bolt hole, sliding bolt 4 and rear bolt hole spiral shell
Line connection, the bottom end of sliding bolt 4 are equipped with ball bearing 8, and location nut 2 is additionally provided on sliding bolt 4, and set bolt 3 is inserted in preceding screw hole
In, it covers and is placed with steel ball 9 and spring 10 in 3 inner cavity of bolt, hold-down bolt 5 is connect with set 3 thread in inner cavity of bolt.
