Abstract
The utility model relates to a measuring instrument for a small-aperture groove, which belongs to the field of detection of small-aperture grooves. A transmission rod is connected with a main body in a sliding manner, a dial indicator is in contact connection with the transmission rod, a gauging spindle is connected with a slide wedge for the transmission rod, and a measuring head is fixedly connected with the gauging spindle. The measuring instrument has the advantages of novel structure, convenience of operation and reliable measurement; by using the principle of the slide wedge, the matched slide wedges are respectively processed on the transmission rod and the gauging spindle matched with the transmission rod, the measuring instrument can enter into or retreat from the small-aperture groove freely, the measuring head can be reliably propped against the generatrix of the small-aperture groove under the locking action of the slide wedge and transferred to the measuring instrument through the transmission rod, and the purpose of accurately measuring the coaxiality relative to the benchmark is achieved; and the measuring instrument is mainly used for an oil ejector which has a small groove diameter and needs to ensure the coaxiality of the groove diameter relative to the benchmark.
Description
Technical field
The utility model belongs to small-bore groove detection range.
Background technology
At present in frock detects, when running into the small-bore groove and detect with respect to the right alignment of benchmark, because of groove footpath little, do not arrange measuring mechanism in the groove fortunately, general employing will not detect, and this groove is also very important with respect to the right alignment of benchmark, though can adopt photoelectron to detect, but the application of photoelectron detection technique in industrial detection also is not very extensive, and operation is not very nimble at some specific position grooves.
Summary of the invention
The utility model provides a kind of small-bore groove measuring instrument, to solve the problem of the bad measurement that exists in the groove measurement of present small-bore.The technical scheme that the utility model is taked is: drive link and body are slidingly connected, and dial gauge is connected with the drive link contact, and measurement axis is connected with the drive link wedge, and gauge head is fixedlyed connected with measurement axis.
The utility model has the advantages that novel structure, easy to operate, measure reliable.Utilize the wedge principle, cooperate wedge by processing on the measurement axis of drive link and cooperation with it, make measuring instrument can enter, withdraw from the path groove, activity freely, and because of the locking of wedge, gauge head only can be leaned on reliably on path groove bus, pass on the meter, reach its right alignment of accurate measurement with respect to benchmark by drive link.It is little to be mainly used in groove such as fuel injector footpath, needs to guarantee the right alignment of groove footpath with respect to benchmark.
