Abstract
The utility model provides an adjustable thread bottom hole depth measuring tool in order to satisfy a requirement of accurate measurement of a depth of a thread hole bottom hole having a relatively small aperture. The adjustable thread bottom hole depth measuring tool comprises a measuring rod provided with standard graduation lines in an axial direction, a sleeve slidably sleeved on the measuring rod, and a positioning screw disposed on a side wall of the sleeve. The side wall of the sleeve is provided with a thread through hole cooperated with the positioning screw in the side wall of the sleeve along a radial direction. The utility model is advantageous in that the adjustable thread bottom hole depth measuring tool is simple and practical, the depth of the bottom hole of the thread hole having the small aperture can be measured conveniently and accurately, the processing quality of the small thread hole can be improved, the insufficient depth of the bottom hole of the thread hole can be prevented, and the effective thread depth can be guaranteed.
Description
Technical field
The utility model relates to a kind of mechanical measuring device.
Background technology
The less threaded hole bottom outlet depth survey difficulty in aperture is large, error is large, controls meeting not in place and causes the effective thread degree of depth not meet design requirement.Therefore, a kind of thread Pilot hole degree of depth measurer that can be simple and practical need to be arranged, satisfy the depth survey of the less threaded hole bottom outlet in aperture.
The utility model content
The utility model provides a kind of adjustable thread Pilot hole degree of depth measurer, with the needs of the degree of depth Measurement accuracy that satisfies the less threaded hole bottom outlet in aperture.
Solution of the present utility model is as follows.
Adjustable thread Pilot hole degree of depth measurer, be provided with on comprising axially the master scale line sounding rod, be slidably socketed the sleeve on sounding rod and be installed on the dog screw of sleeve lateral wall, radially offer the tapped through hole suitable with described dog screw at the sidewall of described sleeve along sleeve.
The end of above-mentioned dog screw is best and sidewall shape sounding rod is suitable, so that dog screw contacts with the measurement pole face when screwing dog screw; Thereby guarantee the stable of location.
The utlity model has following advantage:
The utility model is simple and practical, can easily and accurately measure the bottom outlet degree of depth of the threaded hole of small-bore; Thereby improved the crudy than the minor thread hole, the prevention threaded hole bottom outlet degree of depth is not enough, guarantees effective depth of thread.
The reduced inspection operation easier improves checkability.In use, effectively guarantee product quality, improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1-sounding rod, 2-dog screw, 3-sleeve.
Embodiment
The utility model frock mainly comprises sounding rod 1, dog screw 2 and sleeve 3.Sounding rod is the thread Pilot hole feeler gauge with scale marker, and the data of thread Pilot hole are by obtaining in GB.Sleeve is slidably socketed on sounding rod, and sounding rod can be slided up and down in sleeve freely.Dog screw is arranged on the sidewall of sleeve, and namely the sidewall at sleeve radially offers the tapped through hole suitable with dog screw along sleeve, and dog screw mainly reaches threaded hole when bottom fixation measuring bar at sounding rod and facilitates reading.Whole measuring system can directly obtain measurement data.
The end of dog screw is best and sidewall shape sounding rod is suitable, so that dog screw contacts with the measurement pole face when screwing dog screw; Thereby guarantee the stable of location.
Claims (2)
