Abstract
The invention discloses a threaded hole depth detecting tool, comprising an outer cylinder, a dial indicator and a screw gauge, wherein a strip straight slot is formed in the middle of the outer cylinder, the upper end of the outer cylinder is a cylindrical supporting table, the outer cylinder is provided with an annular groove at the lower part, a detection pin at the lower end of the dial indicator is inserted into the cylindrical supporting table at the upper end of the outer cylinder and penetrates through the supporting table, a detection pin at the lower end of the dial indicator is arranged in the supporting table in a sliding mode, the screw gauge penetrates through the annular groove, an adjusting hand wheel is arranged at the part of the screw gauge positioned on the straight slot, a brake shoe is fixed in the annular groove and sleeved on the screw gauge, and the screw gauge and the brake shoe are arranged in a sliding mode. The screw gauge can be replaced according to the thread demand value of a detected piece to facilitate measurement, and the screw gauge is accurate in reading when detecting the thread depth, convenient to use and particularly suitable for the production field.
Description
Technical field
The present invention relates to cubing technical field, be specifically related to a kind of threaded hole depth detection instrument.
Background technology
In machining process, the processing of internal thread and detection are one of very general operations.In order to reach the object of Measurement accuracy depth of internal thread, just accurately must determine the position of effective thread, removing invalid reach.Therefore, internal thread mainly detects two aspects: thread pitch diameter and depth of internal thread.Survey instrument the most frequently used is at present feeler gauge, is reached the object detecting thread pitch diameter by go side and not-go-end.But in the go side of feeler gauge, process some size grooves, carry out qualitative detection, tolerance is comparatively large, may there is the risk of mistake in testing result because of the collimation error of operating personnel.And use plug thread gauge and slide calliper rule to coordinate to detect, although can be quantitative reflect depth value, complex operation, measurement result is vulnerable to the impact of operating personnel.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of threaded hole depth detection instrument, overcome the deficiencies in the prior art, project organization is reasonable, and screw thread drift can be changed according to the screw thread required value of measured piece, is convenient for measuring, this depth of thread is advised, detect depth of thread accuracy of reading, easy to use, be particularly suitable for production scene and use.
Technical matters to be solved by this invention can be come to be realize by the following technical programs:
A kind of threaded hole depth detection instrument, comprise urceolus, dial gauge and screw thread drift, described urceolus centre position has the groove of strip, urceolus upper end is cylindrical support platform, bottom is for having ring groove, described dial gauge bottom is detected syringe needle and is inserted the cylindrical support platform of urceolus upper end and pass brace table, dial gauge bottom is detected syringe needle and to be slided in brace table setting, described screw thread drift is through ring groove, screw thread drift is positioned at groove position part and is provided with control hand wheel, described ring groove internal fixtion has chock, chock is placed on screw thread drift, screw thread drift and chock slide and arrange.
Described control hand wheel is fixedly installed on screw thread drift, and a part is stretched out to outside control hand wheel in screw thread drift upper end.
Described brace table side is provided with lock(ing) bolt.
Compared with prior art, beneficial effect of the present invention is:
Screw thread drift of the present invention can be changed according to the screw thread required value of measured piece, is convenient for measuring, and this depth of thread is advised, and detects depth of thread accuracy of reading, easy to use, is particularly suitable for production scene and uses.
Accompanying drawing instructions
Fig. 1 is structural representation of the present invention.
Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of threaded hole depth detection instrument, comprise urceolus 1, dial gauge 2 and screw thread drift 3, described urceolus 1 centre position has the groove 101 of strip, urceolus 1 upper end is cylindrical support platform 102, bottom is for having ring groove 103, described dial gauge 2 bottom is detected syringe needle and is inserted the cylindrical support platform 102 of urceolus upper end and pass brace table 102, dial gauge 2 bottom is detected syringe needle and to be slided in brace table setting, described screw thread drift 3 is through ring groove 103, screw thread drift 3 is positioned at groove 101 position part and is provided with control hand wheel 4, control hand wheel 4 is fixedly installed on screw thread drift 2, a part is stretched out to outside control hand wheel in screw thread drift upper end, ring groove 102 internal fixtion has chock 5, chock 5 is placed on screw thread drift 3, screw thread drift and chock slide and arrange, brace table side is provided with lock(ing) bolt.
Existing M18*2 detects the depth of thread, precision 0.01, detects depth range and changes screw thread drift as required, by dial gauge display depth reading, mainly for detection of the effective thread tooth of internal thread.
Detection method: screw thread drift and dial gauge are popped one's head in dial gauge school 0 after close contact, screw thread drift is rotated to turning motionless (close contact) according to hand of spiral when detecting the tested depth of thread, read dial gauge reading, this reading adds the depth of thread of the screw thread drift for detecting and the value of the tested depth of thread.
Screw thread drift can be changed according to the screw thread required value of measured piece, is convenient for measuring.This depth of thread is advised, and detects depth of thread accuracy of reading, easy to use, is particularly suitable for production scene and uses.
It should be noted that, in this article, such as term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
Above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
