Description
Technical field
The utility model relates to a kind of measuring appliance, particularly the fan-shaped counterbore survey instrument of one.
Background technology
For a long time, when fan-shaped counterbore is measured, need to use vernier caliper to estimate and read maximum gauge, it is large that size estimates the error read, and measuring accuracy is low.
Therefore, the present inventor develops a kind of measuring appliance specially, and to realize the Quick Measurement of fan-shaped counterbore, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of fan-shaped counterbore survey instrument, and Quick Measuring measures the maximum gauge of counterbore, improves measurement accuracy and efficiency.
In order to reach above-mentioned purpose, solution of the present utility model is:
Fan-shaped counterbore survey instrument, is made up of sleeve, scale, spacer pin, pin and measuring head; Form mutually through axial hole and radial hole in sleeve, the sidewall of sleeve is offered the viewing window communicated with axial hole; Scale is arranged on the sidewall of sleeve near viewing window; Pin interts in the axial hole of sleeve, and on the sidewall of pin, the radial hole of corresponding sleeve offers stopper slot, and the sidewall of pin is also provided with scale mark; Spacer pin is fixed in radial hole, and the inner end of spacer pin is arranged in stopper slot, coordinates make pin can only mode be arranged in the axial hole of sleeve in axial sliding by spacer pin and stopper slot; Measuring head is fixed on the lower end of pin, the below of measuring head forms the cone matched with fan-shaped counterbore, the vertex of a cone of cone lower end to the upper end overall length of pin equals the axial hole length of sleeve, and when measuring head and pin are in the axial hole of sleeve completely, the scale mark of pin refers to just on the zero graduation of scale.
The below of described pin forms axial screw, and the top of measuring head forms axial stud, coordinates, make measuring head be assembled in the below of pin by axial stud and axial screw.
Magnifier installed by described scale.
The drift angle of described cone is 60o, 90o or 120o.
After adopting such scheme, when the utility model uses, the measuring head identical with counterbore angle is selected to be arranged on pin, and change corresponding scale, be placed on counterbore to be measured by the utility model, pin naturally falls together with measuring head, counterbore is fallen into measuring head, pin sinks thereupon, now, is namely the maximum gauge of counterbore by the scale of scale mark indication on scale of pin.The utility model intuitive display, measures easily and fast, accurately, substantially increases measurement efficiency.

Label declaration
Sleeve 1, axial hole 11, radial hole 12, viewing window 13, scale 2, spacer pin 3, pin 4, stopper slot 41, axial screw 42, scale mark 43, measuring head 5, cone 51, axial stud 52, counterbore 6.
Embodiment
As shown in Figure 1 to Figure 3, the utility model discloses fan-shaped counterbore survey instrument, is made up of sleeve 1, scale 2, spacer pin 3, pin 4 and measuring head 5.
Form mutually through axial hole 11 and radial hole 12 in sleeve 1, the sidewall of sleeve 1 is offered the viewing window 13 communicated with axial hole 11.
Scale 2 is arranged on the sidewall of sleeve 1 by bolt near viewing window 13.Conveniently reading, can install magnifier (not shown) on scale 2.
Pin 4 interts in the axial hole 11 of sleeve 1, and on the sidewall of pin 4, the radial hole 12 of corresponding sleeve 1 offers stopper slot 41, and the sidewall of pin 4 is also provided with scale mark 43.
Spacer pin 3 is fixed in radial hole 12, and the inner end of spacer pin 3 is arranged in stopper slot 41, by the spacing and location fit of spacer pin 3 and stopper slot 41, makes pin 4 can only do axial reciprocating in the axial hole 11 of sleeve 1 and slides.
Measuring head 5 is fixed on the lower end of pin 4, conveniently the assembling of measuring head 5 and pin 4 is fixed and is dismantled, and the below of pin 4 forms axial screw 42, and the top of measuring head 5 forms axial stud 52, coordinate by axial stud 52 and axial screw 42, make measuring head 5 be assembled in the below of pin 4.The below of measuring head 5 is formed and to coordinate with fan-shaped counterbore 6(Fig. 4 shown) cone 51 that matches, conveniently measure the fan-shaped counterbore 1-of various different angles, the utility model can be equipped with multiple measuring head 5, the drift angle of the cone 51 of these measuring heads 5 can be 60o, 90o or 120o etc., and two kinds of measuring heads 5 of 90o and 120o have been shown in Fig. 1.
The utility model assembling as shown in Figure 2, the vertex of a cone of cone 51 lower end to the upper end overall length of pin 4 equals axial hole 11 length of sleeve 1, after the utility model is assembled, pin 4 and measuring head 5 are in axial hole 11 just completely, and, now, the scale mark 43 of pin 4 refers on the zero graduation of scale 2 just.
During the utility model actual measurement, select the measuring head 5 identical with counterbore 6 angle to be arranged on pin 4, and change corresponding scale 2, the utility model is placed on counterbore 6 to be measured, pin 4 naturally falls together with measuring head 5, fall into counterbore 6 to measuring head 5, pin 4 sinks thereupon, now, by the maximum gauge of scale mark 43 indication size and counterbore 6 on scale 2 of pin 4, whole measurement easily and fast, intuitive display, accurately, substantially increases measurement efficiency.
The utility model can change different measuring heads 5 according to the angle difference of counterbore 6.Such as, when counterbore 6 angle is 90o, scale mark 43 decline 10 mm time, indication size is 20mm.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
