Abstract
A kind of blanking bevel protractor, belongs to measurement mechanism field.Comprise the first dip stick, the second dip stick and fixed bar; Described first dip stick is connected by axle with the second dip stick; One end of described fixed bar is connected on the second dip stick by axle; The other end is provided with a projection; Described first dip stick is provided with several pilot holes.By the setting of the first dip stick, the second dip stick and fixed bar, the multiple pilot holes on the first dip stick are utilized to realize the measurement of fixed angle in blanking process, achieve a chi multiplex, blanking bevel protractor described in the utility model can realize independent operation simultaneously, structure is simple, easy to use, turn improve production efficiency while saving human cost, be applicable to promoting the use of.
Description
Technical field
The utility model belongs to measurement mechanism field, particularly relates to a kind of blanking bevel protractor.
Background technology
In industry manufacture field, especially Field of Aviation Manufacturing, the compound substance used often is needed to carry out cutting before use, the number of degrees majority carrying out cutting is fixing angle, existing technology adopts fixing set square to measure mostly, then utilize steel ruler to complete after thread-changing on sheet material fabric to cut out, operation is more, and efficiency is lower.
Summary of the invention
The utility model is intended to solve the problem, and provides a kind of blanking bevel protractor be simple and easy to.
A kind of blanking bevel protractor described in the utility model, comprises the first dip stick, the second dip stick and fixed bar; Described first dip stick is connected by axle with the second dip stick; One end of described fixed bar is connected on the second dip stick by axle; The other end is provided with a projection; Described first dip stick is provided with several pilot holes.Size and the aforementioned projection of described pilot hole match.First dip stick and the second dip stick all can rotate around coupling shaft; Fixed bar can be rotated by the axle on the second dip stick; Realize the fixing of the first dip stick and the second dip stick by the projection of fixed bar one end being inserted in the pilot hole on the first dip stick, thus make to form a fixed angle between the first dip stick and the second dip stick.
A kind of blanking bevel protractor described in the utility model, described first dip stick is provided with three pilot holes, is followed successively by the first pilot hole, the second pilot hole and the 3rd pilot hole.The measurement of three fixed angles can be completed by three pilot holes, realize a chi multiplex.
A kind of blanking bevel protractor described in the utility model, the orientation angle of described first pilot hole is 60 °; The orientation angle of the second pilot hole is 45 °; The orientation angle of the 3rd pilot hole is 30 °.More in the cutting out of aviation composite is above-mentioned three angles, according to the service condition of reality, the first dip stick can arrange the pilot hole of respective angles in use.
A kind of blanking bevel protractor described in the utility model, by the setting of the first dip stick, the second dip stick and fixed bar, the multiple pilot holes on the first dip stick are utilized to realize the measurement of fixed angle in blanking process, achieve a chi multiplex, blanking bevel protractor described in the utility model can realize independent operation simultaneously, and structure is simple, easy to use, turn improve production efficiency while saving human cost, be applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of blanking bevel protractor described in the utility model;
Wherein 1-first dip stick; 2-second dip stick; 3-fixed bar; 4-pilot hole.
Embodiment
A kind of blanking bevel protractor described in the utility model, as shown in Figure 1, comprises the first dip stick 1, second dip stick 2 and fixed bar 3; Described first dip stick 1 is connected by axle with the second dip stick 2; One end of described fixed bar 3 is connected on the second dip stick 2 by axle; The other end is provided with a projection; Described first dip stick 1 is provided with several pilot holes 4.Size and the aforementioned projection of described pilot hole 4 match.First dip stick 1 and the second dip stick 2 all can rotate around coupling shaft; Fixed bar 3 can be rotated by the axle on the second dip stick 2; Realize the fixing of the first dip stick 1 and the second dip stick 2 by the projection of fixed bar 3 one end being inserted in the pilot hole 4 on the first dip stick 1, thus make to form a fixed angle between the first dip stick 1 and the second dip stick 2.
A kind of blanking bevel protractor described in the utility model, described first dip stick 1 is provided with three pilot holes 4, is followed successively by the first pilot hole 4, second pilot hole 4 and the 3rd pilot hole 4.The measurement of three fixed angles can be completed by three pilot holes 4, realize a chi multiplex.
A kind of blanking bevel protractor described in the utility model, the orientation angle of described first pilot hole 4 is 60 °; The orientation angle of the second pilot hole 4 is 45 °; The orientation angle of the 3rd pilot hole 4 is 30 °.More in the cutting out of aviation composite is above-mentioned three angles, according to the service condition of reality, the first dip stick 1 can arrange the pilot hole 4 of respective angles in use.
Embodiment, according to the number of degrees needing cutting during use, is inserted into the projection of fixed bar 3 one end in corresponding pilot hole 4, namely achieves the angle orientation of blanking bevel protractor, utilizes the angle fixed can complete cutting blanking.According to the needs of real work, the conventional number of degrees can be arranged multiple pilot hole 4; The projection of fixed bar 3 one end also can be set to perforate, and latch can be utilized to complete the fixing of fixed bar 3, complete angled fixing with this.
