Description
【Technical field】
It the utility model is related to a kind of detection instrument, and in particular to a kind of internal structure for being used to detect knob and size are
It is no to meet installation standard.
【Background technology】
To enable knob to be accurately installed on products panel, it is necessary to ensure that the outside diameter of knob, internal diameter, chamfering,
Step, axial length are in the range of error permission.General knob demand is big in actual production, due to unspecial inspection
Survey instrument, when detection, need replacing different instruments and go to measure, and inefficiency, takes time and effort, and extend life cycle of the product, therefore
Urgent need wants a kind of instrument that can quickly detect knob internal structure and size to improve detection efficiency.
【Utility model content】
The purpose of this utility model is to provide a kind of instrument for being used to detect knob internal structure and size, to solve
Different instruments is needed replacing when detecting in the prior art to go to measure, inefficiency, takes time and effort, and extends life cycle of the product
Problem.
To achieve the above object, the instrument for being used to detect knob internal structure and size of the utility model is implemented including more
A fan-shaped cylinder, arc radius and the knob interior step radius of the fan-shaped cylinder correspond, the fan-shaped cylinder
Height is corresponded with shoulder height, and the fan-shaped cylinder is superimposed one by one according to arc radius is ascending.
It is preferred that the central angle of all fan-shaped cylinders is not more than 180 °, the bottom of wherein one or more fan-shaped cylinders
There is circular arc chamfering, the circular arc chamfering is corresponded with chamfering inside knob.
It is preferred that the height of the fan-shaped cylinder superposition is consistent with knob axial length.
It is preferred that the instrument can also include an arc radius peripheral fan-shaped cylinder consistent with knob outside diameter,
The periphery fan-shaped cylinder is superimposed on the superiors.
It is preferred that the instrument can also include a handle, for taking conveniently.
It is preferred that the instrument is made of metal material.
Compared with prior art, the tool construction for being used to detect knob internal structure and size of the utility model is implemented
Simply, it is easy to carry, it is workable, the cumbersome measurement of multiple types of tools is avoided, accelerates detection efficiency, mitigates the labor of staff
Fatigue resistance, practicality is preferable, application easy to spread, has larger practical value.
【Brief description of the drawings】
Fig. 1 is originally to apply the structure diagram that utility model is used to detect the instrument of knob internal structure and size.
Fig. 2 is originally to apply the structural representation that utility model is used to detect another angle of the instrument of knob internal structure and size
Figure.
【Embodiment】
Please refer to Fig.1 the knot for being used to detect the instrument of knob internal structure and size with shown in Fig. 2, being the utility model
Structure schematic diagram.That implements the utility model includes multiple fan-shaped cylinders 10 for detecting knob internal structure and the instrument 1 of size,
The arc radius of the fan-shaped cylinder 10 is corresponded with 2 interior step of knob, 20 radius, the height of fan-shaped cylinder 10
Highly corresponded with step 20, the fan-shaped cylinder 10 is superimposed one by one according to arc radius is ascending, all sectors
The central angle of cylinder 10 is not more than 180 °, can observe whether frock coincide with 2 internal structure of knob, and whether scale error is permitting
Perhaps in the range of, circular arc chamfering is arranged at the bottom of wherein one or more fan-shaped cylinders 10, and the circular arc chamfering falls with the inside of knob 2
Angle corresponds, and by observation it may determine that whether chamfering radian is accurate, reduces time and the difficulty of the internal circular arc chamfering of measurement
Degree.
The height that the fan-shaped cylinder 10 is superimposed is consistent with 2 axial length of knob.It is described to be used to detect knob internal junction
Structure and the instrument of size can also include an arc radius peripheral fan-shaped cylinder 11 consistent with knob outside diameter, and the periphery is fan-shaped
Cylinder 11 is superimposed on the superiors, for measuring whether 2 outside diameter of knob meets the requirements.It is described be used for detect 2 internal structure of knob and
The instrument of size can also include a handle 12, easy to take.Reusability is needed in view of frock, therefore takes hardness larger
Metal material be made.
Compared with prior art, the tool construction for being used to detect knob internal structure and size of the utility model is implemented
Simply, it is easy to carry, it is workable, the cumbersome measurement of multiple types of tools is avoided, accelerates detection efficiency, mitigates the labor of staff
Fatigue resistance, practicality is preferable, application easy to spread, has larger practical value.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model
Scope of the claims.
