Description
Technical field
The utility model is related to a kind of inner diameter measuring devices.
Background technology
Currently, being typically all by means of inside micrometer, air-gauge for the detection of inner hole of workpiece, feeler gauge etc. measures work
Tool is detected.But existing defects when being measured using these survey tools；For example, the measuring speed of inside micrometer
It is relatively slow, and the measurement range of air-gauge and feeler gauge is dumb.Therefore, it in order to avoid the defect of existing survey tool, needs to set
It is flexible to count a kind of measurement range, and conveniently inner diameter measuring device.
Utility model content
It is reasonable for structure the purpose of this utility model is to provide a kind of inner diameter measuring device, it can be effectively to workpiece
Endoporus is detected.
To achieve the above object, the technical solution of the utility model is a kind of inner diameter measuring device of design, including amesdial,
Cylinder is detected, and for connecting amesdial and detecting the connecting shaft of cylinder；It is equipped with movable sleeve in the detection cylinder, the movable sleeve
One end is outside detection cylinder, and for the other end inside detection cylinder, the movable sleeve can be along detection cylinder axial movement, the movable sleeve and institute
The input terminal for stating amesdial is connected, and the movable sleeve is located at one end outside detection cylinder and is equipped with handle, which is located at inspection
One end outer wall surveyed inside cylinder is equipped with groove, which is the inclined-plane being inclined outwardly；The detection cylinder is equipped with activity and surveys
Head, which can move radially along detection cylinder, and one end that the activity gauge head is located in detection cylinder is equipped with hemispherical projections,
The hemispherical projections are butted on above-mentioned inclined-plane, are set with gauge head resetting spring on the activity gauge head, the gauge head resetting spring one end
It is fixed on detection cylinder inner wall, the other end is fixed on the inside of hemispherical projections.
Preferably, the movable sleeve resetting spring for being set in movable sleeve, the movable sleeve resetting spring are equipped in the detection cylinder
Detection cylinder inner wall is fixed in one end, and the other end is fixed on movable sleeve outer wall.
Preferably, the handle is in the form of annular discs.
The operation principle of the utility model is：In use, by pull-up handle, movable sleeve is made to be moved to amesdial direction,
Movable sleeve resetting spring is compressed；In movable sleeve moving process, hemispherical projections are under gauge head action of reset spring along groove
Inclined-plane moved to groove slot bottom direction, so that movable gauge head is bounced back.Detection cylinder is stretched into inner hole of workpiece after the completion, then unclamps hand
Handle is actively set under movable sleeve action of reset spring and is moved far from amesdial, because elastic force caused by movable sleeve resetting spring is big
The elastic force caused by gauge head resetting spring, therefore the inclined-plane of groove will drive hemispherical projections to be moved far from groove slot bottom, make work
Dynamic gauge head is stretched out and is contacted with inner hole of workpiece hole wall, after the completion reading numerical values, to judge the error of inner hole of workpiece.
The advantages of the utility model and advantageous effect are：Effectively inner hole of workpiece can be detected.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of movable sleeve and movable gauge head cooperation in the utility model.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
The utility model specific implementation technical solution be：
As depicted in figs. 1 and 2, a kind of inner diameter measuring device, including amesdial 1, detection cylinder 2, and for connecting thousand points
The connecting shaft 3 of table 1 and detection cylinder 2；It is equipped with movable sleeve 4 in the detection cylinder 2, one end of the movable sleeve 4 is outside detection cylinder 2
Portion, the other end is inside detection cylinder 2, and the movable sleeve 4 can be moved axially along detection cylinder 2, the movable sleeve 4 and the amesdial 1
Input terminal be connected, the movable sleeve 4 be located at detection cylinder 2 outside one end be equipped with handle 5, the movable sleeve 4 be located at detect cylinder 2
Internal one end outer wall is equipped with groove, which is the inclined-plane 6 being inclined outwardly；The detection cylinder 2 is equipped with movable gauge head
7, which can move radially along detection cylinder 2, and one end that the activity gauge head 7 is located in detection cylinder 2 is convex equipped with hemispherical
8 are played, which is butted on above-mentioned inclined-plane 6, is set with gauge head resetting spring 9 on the activity gauge head 7, which resets
Detection 2 inner wall of cylinder is fixed in 9 one end of spring, and the other end is fixed on 8 inside of hemispherical projections.
Also, the movable sleeve resetting spring for being set in movable sleeve 4, the movable sleeve resetting spring are equipped in above-mentioned detection cylinder 2
Detection 2 inner wall of cylinder is fixed in one end, and the other end is fixed on 4 outer wall of movable sleeve.
In addition, above-mentioned handle 5 is in the form of annular discs.
The operation principle of the utility model is：In use, by pull-up handle 5, movable sleeve 4 is made to be moved to 1 direction of amesdial
