Abstract
The utility model discloses an inside micrometer for hole distance measuring. The inside micrometer comprises an inside micrometer main body and two internal measurement mechanisms fixed on a bent measuring head of the inside micrometer main body. The mechanisms comprise at least two fixing screws, two symmetrically arranged cylindrical measuring heads with diameters smaller than those of measured holes and two fixing frames having the cylindrical measuring heads fixed thereon. The fixing frames are fixed on the bent measuring head of the inside micrometer main body through the fixing screws. By means of the inside micrometer, the technical problem of precisely measuring the hole distance between two small holes can be well solved.
Description
Technical field
The utility model relates to a kind of micrometer inside caliper of measuring 2 pitch-rows between the hole with less internal diameter.
Background technology
Please refer to Fig. 1, Chinese patent application number is that 201110286483.2 micrometer inside caliper is mainly measured by 2 on it larger holes of crooked gauge head pair radius, can cause measuring accurately owing to the arc edge of the arc limit on the gauge head greater than circular hole if measure less hole, aperture, this causes some can't be measured accurately the very high workpiece of dimensional requirement.
The utility model content
The purpose of this utility model provides a kind of micrometer inside caliper of measured hole distance, solves technical matters how to use micrometer inside caliper accurately to measure the pitch-row between two apertures.
The micrometer inside caliper of measured hole distance, comprise the micrometer inside caliper main body, be fixed in 2 on the crooked gauge head of micrometer inside caliper main body and survey mechanism that this mechanism comprises that at least 2 gib screws, 2 symmetrically arranged diameters are less than the cylindrical gauge head of measured hole diameter, 2 fixed mounts that make cylindrical gauge head side fixed thereon; Fixed mount is fixed on the crooked gauge head of micrometer inside caliper main body by gib screw.
The longitudinal section of described cylindrical gauge head is "T"-shaped.
The longitudinal section of described cylindrical gauge head becomes " I " shape.
Described fixed mount has crooked gauge head standing groove, and crooked gauge head is arranged in this standing groove.
The surfaceness of described cylindrical gauge head is 5nm-10nm.
The beneficial effects of the utility model are:
1, is 5nm-10nm owing to having adopted 2 symmetrically arranged diameters less than the cylindrical gauge head of measured hole diameter and the surfaceness of these 2 gauge heads, can measures accurately 2 pitch-rows between the aperture like this.
2, because the longitudinal section of cylindrical gauge head becomes " I " shape, when wear and tear in its top, can utilize the bottom to measure like this, the equipment practicality is provided.
Description of drawings
Fig. 1 is the structural representation of existing micrometer inside caliper;
Fig. 2 is the interior synoptic diagram of surveying mechanism that adopts in the specific embodiment;
1. micrometer inside caliper main bodys among the figure, 2. interior survey mechanism, 3. gib screw, 4. cylindrical gauge head, 41. tops, 42. bottoms, 5. fixed mount, 51. crooked gauge head standing grooves, 6. crooked gauge head.
Embodiment
Please refer to Fig. 2, the micrometer inside caliper of the measured hole distance among the figure, comprise that a micrometer inside caliper main body 1, two are fixed on the interior survey mechanism 2 on the micrometer inside caliper main body 1 crooked gauge head 6, this mechanism comprises that two gib screws 3, two symmetrically arranged diameters are less than the cylindrical gauge head 4 of measured hole diameter, two fixed mounts 5 that make cylindrical gauge head 4 sides fixed thereon; Thereby the surfaceness of cylindrical gauge head 4 is 5nm-10nm realizes high-acruracy survey; Fixed mount 5 has crooked gauge head standing groove 51, and crooked gauge head 6 is arranged in this standing groove, and fixed mount 5 is fixed on the crooked gauge head 6 of micrometer inside caliper main body 1 by gib screw 3.Cylindrical gauge head 4 among the figure is right cylinder with the level, and its longitudinal section is "T"-shaped; Certainly also gauge head can be made " worker " shape right cylinder, namely the longitudinal section becomes " I " shape, when its top 41 and workpiece contact surface abrasion, can utilize bottom 42 to measure like this, and the equipment practicality is provided.
