Abstract

A measuring means for diameter of dial indicator comprises a dial indicator graduated disc, a jacket cylinder and a measuring rod which are integrally matched with the graduated disc, which is characterized in that the measuring end of the jacket cylinder is fixed with a left measuring claw through a set bolt, the right side of the left measuring claw is parallel connected with a right measuring claw through an upper and a lower guide shafts, and the right end of the overcasting staff is overlapped with the right measuring claw. Compared with the prior art, the measuring means has the characteristics of simple structure, easy making, convenient operation and high measurement precision, can be used in required places, and can extremely conveniently measure the precise dimension of the diameter of work-piece.

Description

The dial gauge inner diameter measuring device
Technical field
The utility model relates to the inner diameter measurement field of tool, specifically is a kind of dial gauge inner diameter measuring device
Background technology
At present, machine work or produce in the maintenance industry measures to inner diameter of workpiece that all to adopt vernier caliper be survey instrument, and vernier caliper is simple in structure, cheap, can satisfy the technical requirement of common industry.But because the contact point of vernier caliper is very little, be difficult to find accurately its center line to the measurement of workpiece diameter the time, the vernier caliper precision is relatively poor again, so the numerical error of measuring is bigger, uses then not competent as the place of having relatively high expectations in measuring accuracy.
The utility model content
There is the bigger and awkward defective of measuring error in the purpose of this utility model at prior art exactly, and a kind of dial gauge inner diameter measuring device is provided.
Its technical scheme is: comprise the dial gauge index dial and with the chuck tube and the sounding rod of index dial overall co-ordination.The measuring junction of chuck tube is fixed with left measuring claw by set bolt, and left measuring claw right side is connected with right measuring claw by two axis of guides up and down are parallel, and the right-hand member of sounding rod overlaps with right measuring claw and cooperates.
The lower end of described left measuring claw and right measuring claw also is respectively equipped with measuring head.
The characteristics that the utility model has compared with prior art is simple in structure, making is easy, easy to operate and measuring accuracy is high are used in the place of needs, can measure the accurate dimension of workpiece diameter very easily.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model
Embodiment:
Embodiment, with reference to accompanying drawing, this device comprises dial gauge index dial 1 and the chuck tube 2 and the sounding rod 6 that cooperate with index dial 1 body.The measuring junction of chuck tube 2 is fixed with left measuring claw 3 by set bolt 7, and left measuring claw 3 right sides are connected with right measuring claw 4 by two axis of guides up and down 5 are parallel, and the right-hand member of sounding rod 6 overlaps with right measuring claw 4 and cooperates.The right-hand member that the lower end of a left side measuring claw 3 and right measuring claw 4 also is respectively equipped with 8, two axis of guides 5 of measuring head passes right measuring claw 4 and can horizontally slip.
When using the utility model, measuring head 8 is put into the internal diameter of measured workpiece, the spacing of regulating left measuring claw 3 and right measuring claw 4 is to measured workpiece inner diameter wall diameter maximum, and this moment, sounding rod 6 promptly can drive the accurate dimension that dial gauge index dial 1 demonstrates the measured workpiece internal diameter thereupon.

Claims (2)

1, a kind of dial gauge inner diameter measuring device, comprise the dial gauge index dial and with the chuck tube and the sounding rod of index dial overall co-ordination, it is characterized in that: the measuring junction at the chuck tube is fixed with left measuring claw by set bolt, measuring claw right side, a left side is connected with right measuring claw by two axis of guides up and down are parallel, and the right-hand member of sounding rod overlaps with right measuring claw and cooperates.
2, according to the described dial gauge inner diameter measuring device of claim 1, it is characterized in that: the lower end of described left measuring claw and right measuring claw also is respectively equipped with measuring head.
