The cone of the slide bar right part in the said structure is a measuring head, and its conicity equals 2 times of values of measured piece endoporus chamfer dimesion, and its circular cone outside diameter is greater than the measured piece diameter of bore.Slide bar can be done in the pipe orifice limitedly to move relative to straight line at cover, and amount of movement is by the control of the slotted hole on spacer pin of installing on the sleeve pipe and the slide bar, and spring is a kind of pressure spring, and slide bar, sleeve pipe after will relatively moving after measuring each time return to initial position.
The utlity model has and can adjust slide bar and sleeve pipe relative position structure, convenient, fast during actual measurement, accurate after dial gauge is determined measuring basis through returning to zero, be particularly suitable for the batch piece test.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the accurately machined ring standard gauge synoptic diagram of measured piece endoporus chamfer dimesion;
Fig. 3 is the partial structurtes synoptic diagram that latch segment locking connects dial gauge and sleeve pipe.
Embodiment
The utility model is a kind of measurer of measuring the endoporus chamfer dimesion, and it is made of jointly slide bar 2, sleeve pipe 3, spacer pin 4, spring 5, latch segment 6, screw 8, dial gauge 7 and ring standard gauge 1.Described sleeve pipe 3 is a kind of hollow pipe components, and left end hole internal diameter matches with the table bar of dial gauge 7, is provided with shaft orientation opening groove on this section tube wall between two parties, is connected by latch segment 6 and screw 8 lockings.Sleeve pipe 3 right-hand member through hole tube walls are provided with the hole that spacer pin 4 is installed perpendicular to axis, and tube wall is up and down run through in this hole, on one side hole on the tube wall be tapped through hole, the hole on the tube wall of opposite is a round tube hole.Described slide bar 2 is the solid step axle, insert behind the pocketed springs 5 on the left end diameter segment in sleeve pipe 3 inner chambers and left end endoporus clearance fit, slide bar 2 left sides contact with the gauge outfit of dial gauge 7, slide bar 2 right-hand members are provided with segment length's circular hole than enlarged diameter section cylinder upper edge axis direction, this section cooperates with sleeve pipe 3 right-hand member interporal lacunas, the spacer pin of installing on the sleeve pipe 3 right-hand member tube walls 4 is penetrated wherein, and control slide bar 2 moves as finite straight line with respect to sleeve pipe 3.Slide bar 2 right parts are provided with the cone with measured bore chamfering corresponding size.The measured bore of present embodiment is φ 16mm, falls 1 * 45, so the conicity of slide bar 2 right part cones is 90 °, the circular cone diameter at butt end is φ 18.5mm.
The utility model will be adjusted the indicator of dial gauge 7 to zero-bit with ring standard gauge 1 analogue measurement before actual measurement.Concrete set-up procedure is as follows: use the ring standard gauge 1 that forms by the finishing of measured piece endoporus chamfer dimesion to aim at the cone of slide bar 2 right parts, the coning angle of this cone equals 2 times of values of ring standard gauge 1 chamfering, the elastic force that promotion sleeve pipe 3 makes slide bar overcome spring 5 moves backward, the table bar that promotes dial gauge 7 behind slide bar 2 when moving is with moved further and drive indicator and rotate, only coincide until the right side of sleeve pipe 3 and the end face of ring standard gauge 1, the indicator of dial gauge 7 also stops operating, adjust the zero graduation line of dial gauge 7 dial plates and aim at the indicator position, with this as measuring basis.After removing ring standard gauge 1, slide bar 2 and sleeve pipe 3 return to initial position under the effect of spring 5, and the indicator of dial gauge 7 also returns to initial position.During actual measurement the cone in the utility model is aimed at the chamfering endoporus of measured piece, promote to move after sleeve pipe 3 makes slide bar 2, coincide into until the right side of sleeve pipe 3 and the end face of measured piece, the difference of zero graduation line is exactly measured bore chamfering and the error amount that designs interior Hole chamfering on the indicator of dial gauge 7 and the dial plate.
