Abstract
The utility model discloses a quick measuring device for holes, which is a hard rod cylinder. The generating line cone surface of a long table cone or an oval cone is milled with a V-shaped groove with a central angle section, and one groove surface of the groove is provided with a graduated scale with a hole diameter along the generating line. The thick end of the cone body is also provided with a handle convex table, and the convex table is provided with a slide gauge groove. The groove is sheathed with an indicating needle type gauge rod, and the point of the corner-shaped pointer of the gauge rod extends to the inside of the V-shaped groove to indicate the reading of the hole diameter on the scale. The device has the advantages of convenient use, quick speed, and high measuring precision and indirectly detect the central inclination and the circularity of the hole.
Description
The utility model relates to the improvement of machinery tools, specifically is a kind of quick gaging hole device, and it belongs to machine work survey instrument technical field.
To the measurement of machine work through hole, the logical no-go gage of general employing is measured in the prior art.The actual numerical value in aperture in the margin tolerance of regulation, can not accurately be read in the aperture that this survey instrument can only be checked set hole whether.Because this logical no-go gage is a kind of excellent cylinder of standard, the direct reading of no indicated number value on its cylinder.It is micrometer inside caliper and vernier caliper that a kind of survey instrument is arranged, and it can measure the numerical value of aperture (internal diameter), but this instrument measuring speed is slow, can not check the degree of tilt of the center line in this hole.
The purpose of this utility model is the defective that will overcome above-mentioned gaging hole instrument, designs a kind of quick gaging hole device.This device will be able to detect the aperture exact value and the deviation of the bolt hole of processing quickly and accurately, can also measure the center line degree of tilt of bolt hole.
Task of the present utility model is finished by following technical scheme, developed a kind of quick gaging hole device, it is a hard rod cylinder, milling has " V " shape groove in central angle cross section on the bus conical surface of oval cone or elliptical table cone, is provided with the rule in mark aperture at a certain groove face upper edge of this groove bus.
Described excellent cylinder, its cylinder can also be positive terrace with edge cylinder shapes, and milling has " V " shape groove of axle center angular cross section on a certain bus faceted pebble of its terrace with edge cylinder, are provided with the rule in mark aperture at a certain groove face upper edge of this groove crest line.
Described oval centrum, or positive terrace with edge cylinder, or elliptical table cone, the particle size end of its awl or cylinder is provided with the handle boss, and this boss is provided with the slide gauge groove parallel with central axis, is coated with pointer gauge bar in this groove, on the external groove sidevall of this groove, be provided with the bolt that passes cell wall, the bolt end of this bolt bears down on one on this gauge bar, and the tip of the turning shape pointer of this gauge bar extends in " V " shape groove, thereby indicates the aperture reading on the rule.
Described gap slot, the angular range at its central angle or angle, axle center is the 15-90 degree.
Described rule, its meter full scale represents promptly that at 5-50mm the gaging hole diameter is at 5- 50mm; The scale division value of its scale is 0.1-0.01mm.
The utility model has the advantages that: simple in structure, easy to use, can measure the aperture numerical value of machining hole quickly and accurately, its scale division value is 0.01mm.But this device is the degree of tilt of the center line of indirect detection machining hole and the circularity in hole also.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is that the gaging hole device is at the user mode synoptic diagram of measuring machining hole;
Fig. 2 be the gaging hole device measure the machining hole degree of tilt the user mode synoptic diagram;
Fig. 3 is the right view of Fig. 1.
Referring to Fig. 1-3, this fast a gaging hole device be the excellent cylinder of making by hard alloy steel, central angle is arranged is " V " shape groove 2 in 90 degree cross sections in milling on the bus conical surface 1 of oval cone, is provided with the rule 3 in mark aperture at a certain groove face upper edge of this groove 2 bus.The scale range scope of this rule 3 is 10-30mm.Particle size end in this cone is provided with handle boss 4.This boss 4 is provided with the slide gauge groove 6 parallel with central axis 5.Be coated with pointer gauge bar 7 in this groove 6.On the external groove sidevall of this groove 6, be provided with the bolt 8 that passes cell wall.The bolt end of this bolt 8 bears down on one on this gauge bar 7, plays the role of positioning.The tip of the turning shape pointer 9 of this gauge bar 7 extends in this gap slot, indicates aperture reading on the rule 3 by these pointer 9 footing edges.
The use of this gaging hole device is: earlier hand-held handle boss 4 with oval cone of gaging hole device under the situation that does not add any external force, insert and stretch in the machining hole 10 to be measured, pointer 9 footing edges with pointer gauge bar 7 abut against on the outer rim plane in this hole again, at last bolt 8 are tightened on this gauge bar 7.Because oval cone is vertically to be deep in the machining hole 10 to be measured, then the pointer 9 of this gauge bar 7 can clearly indicate the pin-point reading that scale reading 15.35mm is this hole 10.If it is gapped with the peritreme of machining hole 10 to be measured to estimate the bus conical surface 1 of this device, show that then there is roundness deviation in this hole 10.If the center line in this hole 10 tilts, as shown in Figure 2, the pointer 9 footing edges of this gauge bar 7 and this hole 10 outer rim planar shaped are α at angle, and this angle [alpha] is the degree of tilt of the center line in this hole 10.
