Abstract
The invention relates to a gauge used for measuring the inner groove diameter of an elongated hole, which comprises a caliper gauge, a dial indictor, an adjustment lever and a spring, wherein the caliper gauge is of a pincer-shaped structure and formed by hinging two measuring rods, one of the measuring rods of the caliper gauge is fixedly provided with the dial indicator, the other measuring rod is fixedly provided with the adjustment lever, the adjustment lever corresponds to the dial indicator in position, the length of the adjustment lever relative to the measuring rods can be adjusted, and measuring ends of the two measuring rods are connected through the spring. The gauge provided by the invention is simple in structure, convenient to use, convenient for measurement at any time in processing at the production field, can improve the processing quality and reduce the processing rejection rate, and has the characteristics of high detection efficiency and high universality.
Description
Technical field
The present invention relates to detection technique field, particularly a kind of cubing for measuring elongated hole hole necking diameter.
Background technology
When processing desk-top drill press spindle, need to process a relief groove at the internal taper hole end of main shaft, this relief groove is mainly used in the grinding of follow-up internal taper hole, this relief groove of turning has size tolerance requirements, if the diameter of relief groove is too little, the emery wheel front end of grinding internal taper hole may be caused to touch the end, affect internal taper hole machining precision, and processing peril easily occurs.Because the internal taper hole of main shaft is more elongated, small end minimum diameter is little, the size Control of this relief groove of turning can only lean on compound tool rest and cutter to control, therefore the physical size processed is unstable, and due to internal taper hole more less toward inside dimension, so use common cubing cannot measure the diameter of relief groove.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, providing a kind of structure simple, easy to use, for measuring the cubing of elongated hole internal slot diameter.
For solving the problems of the technologies described above, present invention employs following technical scheme:
For measuring the cubing of elongated hole internal slot diameter, comprise calliper, dial gauge, adjuster bar and spring, described calliper is pincer structure, form by two sounding rods are hinged, one of them sounding rod of described calliper is installed with dial gauge, another sounding rod is installed with adjuster bar, described adjuster bar is corresponding with the position of dial gauge, the length of described adjuster bar relative measurement bar can regulate, and the measuring junction of described two sounding rods is connected by spring.
Further, be threaded connection between described adjuster bar and sounding rod.
Closer, described spring adopts Compress Spring.
The beneficial effect that the present invention has:
1) structure is simple, easy to use, is convenient to the measurement at any time that production scene adds man-hour, and the quality problems of easy Timeliness coverage process, improve crudy, reduce processing rejection rate;
2) adopt dial gauge reading to compare measurement, straightforward, easy to operate, detection efficiency is high;
3) coordinated by the height of adjustment transfer block and ring standard gauge or outside micrometer check and correction, highly versatile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, calliper; 2, dial gauge; 3, adjuster bar; 4, spring; 5, sounding rod; 6, measuring junction.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, for the cubing for measuring elongated hole internal slot diameter, comprise calliper 1, dial gauge 2, adjuster bar 3 and spring 4, described calliper 1 is pincer structure, form by two sounding rods 5 are hinged, one of them sounding rod 5 of described calliper 1 is installed with dial gauge 2, another sounding rod 5 is installed with adjuster bar 3, described adjuster bar 3 is corresponding with the position of dial gauge 2, the length of described adjuster bar 3 relative measurement bar 5 can regulate, and the measuring junction 6 of described two sounding rods 5 is connected by spring 4.
Be threaded connection between described adjuster bar 3 and sounding rod 5.
Described spring 4 adopts Compress Spring.
During measurement, dial gauge 2 is arranged on the sounding rod 5 of calliper 1, measuring junction 6 ring standard gauge or the outside micrometer check and correction of calliper 1, the length of adjustment adjuster bar 3, dial gauge 2 is made to compress 0.3 ~ 0.5mm, secured adjusted bar 3, and be zero by dial gauge 2 check and correction, compare measurement in this, as measuring basis.
