Abstract
The utility model relates to a multi-purpose rule, belonging to an instrument for measuring the angle and the length; the multi-purpose rule is especially suitable for the measurement of the angle of the drill head. The multi-purpose rule is composed of a main rule, an auxiliary rule, an indicated needle and a shaft. The main rule (1) is provided with a graduation marking line for measuring 0 DEG-180 DEG semi-circles; the center of circles of the semicircles are provided with bores; the edge of the upper rule is provided with the marking line of the straight rule; the auxiliary rule (2) is provided with a notch; the indicated needle (3) is provided with a notch. The utility model has the advantages of simple structure, convenient operation.
Description
A kind of multipurpose ruler belongs to angle, measurement of length instrument, is specially adapted to the measurement of drill bit.
In mechanical industry, during the hole of processing parts, need use the drill bit of different angles according to the unlike material of part, the angle of drill bit needs frequent reconditioning.Whether the drill bit that how to detect after the reconditioning meets needed angle, and the common practice is to rely on operator's vision to determine there is not beasurement base, thereby the drill bit after the reconditioning, the error in the specialized range often occurs surpassing, directly influences the precision of processing parts.When two angles that especially relative drill bit body center line is constituted were different, quality problems such as hole deviation, Kong Da can appear in the hole of part to be processed, and cause part to be scrapped, and cause waste.
The purpose of this utility model is to provide a kind of multipurpose ruler simple in structure, easy to use, with low cost.
Task of the present utility model be achieved in that multipurpose ruler by main scale (1), pay chi (2), pointer (3), axle (4,5) and form.It is 0 °～180 ° semicircle calibration groove that main scale (1) is provided with measurement range, the center of circle of semicircle is provided with the hole, pay chi (2) and be provided with notch, pointer (3) is provided with notch, axle (4) is penetrated the circle center hole of main scale (1) semicircle and the notch of pointer (3), main scale (1) is connected with pointer (3).Axle (5) is penetrated the notch of pair chi (2) and the notch of pointer (3), a pair chi (2) is connected with pointer (3).
The last chi limit of the main scale of multipurpose ruler (1) is provided with the ruler groove.
Use multipurpose ruler of the present utility model, can accurately measure the needed angle of drill bit after the reconditioning.Be simple in structure and convenient in use.
The utility model is described in further detail to utilize accompanying drawing below.
Accompanying drawing 1 is the structural drawing of multipurpose ruler.
With reference to attached Fig. 1 and 2, multipurpose ruler is made up of main scale (1), pair chi (2), pointer (3), axle (4,5) and two fastening caps (6).Main scale (1) is provided with the semicircle calibration groove of 0 °～180 ° of measurement ranges, and the center of circle of semicircle is provided with the hole, and last chi limit is provided with the ruler groove, pays chi (2) and is provided with notch, and pointer (3) is provided with notch.Axle (4) is penetrated the circle center hole of main scale (1) semicircle and the notch of pointer (3), and axle (4) makes main scale (1) be connected with pointer (3) with fastening cap (6).Axle (5) is penetrated the notch of pair chi (2) and the notch of pointer (3), and axle (5) makes a pair chi (2) be connected with pointer (3) with fastening cap (6).
Main scale (1), pair chi (2) and pointer (3) can be used metal material, plastics or producing wood, during for plastic ruler, at the reverse side groove of chi, during for metal chi or wooden rule, at the front groove.
Drill bit shown in accompanying drawing 1 double dot dash line is the signal of measurement state, with frame of the bit parallel with pay a chi (2) and contact, two summits of drill bit angle contact with the B point at A with main scale (1), pointer (3) and pair chi (2), pointer (3) respectively, be threaded with the axle head of fastening cap (6), respectively main scale (1), pointer (3) and pair chi (2), pointer (3) fixed with axle (4,5).The indicated angle of pointer (3) this moment is the actual angle of drill bit.
Claims (2)
1, a kind of multipurpose ruler that is used for angle, linear measure longimetry, it is characterized in that forming by main scale (1), pair chi (2), pointer (3) and axle (4,5), it is 0 °～180 ° semicircle calibration groove that main scale (1) is provided with measurement range, the center of circle of semicircle is provided with the hole, pay chi (2) and be provided with notch, pointer (3) is provided with notch, axle (4) is penetrated the circle center hole of main scale (1) semicircle and the notch of pointer (3), main scale (1) is connected with pointer (3), axle (5) is penetrated the notch of pair chi (2) and the notch of pointer (3), a pair chi (2) is connected with pointer (3).
2, multipurpose ruler according to claim 1 is characterized in that the last chi limit of main scale (1) is provided with the ruler groove.
