Abstract
The utility model discloses a kind of threaded hole depth detection instrument, including detecting screw rod（1）, in the detection screw rod（1）On be provided with alignment line（2）, in the detection screw rod（1）On be provided with detection scale（3）, in the detection scale（3）On be provided with graduation mark（4）, the detection screw rod（1）Lower face is to alignment line（2）Length be equal to detection scale（3）Lower end is to graduation mark（4）The length of zero graduation.The utility model has the advantages that simple in structure, easy to operate, of low cost, and fast and accurately screw thread hole depth can be detected using it, and it is accurate not only to detect data, and detection efficiency is higher, eliminates calculating link, improves work efficiency.
Description
Technical field
The utility model is related to a kind of detection instruments, particularly a kind of threaded hole depth detection instrument.
Background technology
At present, in existing manufacturing process, the processing for the threaded hole of parts is highly developed technology, but
It is, during hole processing, it is necessary to the depth of threaded hole is detected, be confirmed whether to reach projected depth.It is now current
The depth detection of threaded hole is generally threaded into using screw rod in hole, then with vernier caliper measurement exposed portion, it is total by screw rod
Long size subtracts screw rod exposed portion and calculates the method for screw thread hole depth to measure the depth of threaded hole, although this method can
Row, still, the detection of screw thread hole depth is carried out with the method, and not only normalization is poor, efficiency is low, also, is also easy to calculate
Mistake causes the underproof accident of product batch to occur.
Utility model content
The purpose of this utility model is just to provide a kind of display accurately, can quickly obtain the screw thread hole depth of screw thread hole depth
Spend detection instrument.
The purpose of this utility model is that technical solution in this way is realized, a kind of threaded hole depth detection instrument, bag
Detection screw rod is included, alignment line is provided on the detection screw rod, detection scale is provided on the detection screw rod, described
Graduation mark is provided on detection scale, the length of the detection screw rod lower face to alignment line is equal to detection scale lower end to scale
The length of line zero graduation.
Wherein, the detection scale includes the body that section is cylinder, is vertically arranged in the body through through hole,
The detection screw rod passes through the observation window platform for through through hole, being provided on the body outer wall and being communicated with through through hole, institute
It states graduation mark and is arranged on observation window platform surface.
Detection scale drops in order to prevent, the lower part through through hole is provided with limited step, in the detection spiral shell
Bar lower part is provided with the positive stop lug boss with limited step cooperation.
For the ease of tightening, it is provided in the upper end of the detection screw rod and tightens knob.
By adopting the above-described technical solution, the utility model is with simple in structure, easy to operate, low-cost excellent
Point can fast and accurately be detected screw thread hole depth using it, not only detect data it is accurate, and detection efficiency compared with
Height eliminates calculating link, improves work efficiency.
Description of the drawings
The description of the drawings of the utility model is as follows：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the detection screw-rod structure schematic diagram of the utility model；
Fig. 3 is the detection scale structure schematic diagram of the utility model；
Fig. 4 is the sectional view in native country 3.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim scope claimed.
Embodiment 1：As shown in Figure 1,2,3, 4, a kind of threaded hole depth detection instrument, including detecting screw rod 1, in the inspection
It surveys on screw rod 1 and is provided with alignment line 2, detection scale 3 is provided on the detection screw rod 1, set on the detection scale 3
There is graduation mark 4, the length of detection 1 lower face of screw rod to alignment line 2 is equal to detection 3 lower end of scale to 4 zero-bit of graduation mark and carves
The length of degree.
Wherein, the detection scale 3 includes the body that section is cylinder, is vertically arranged in the body through through hole
5, the detection screw rod 1 passes through, through through hole 5, to be provided on the body outer wall puts down with the observation window communicated through through hole 5
Platform 6, the graduation mark 4 are arranged on 6 surface of observation window platform.
It comes off in order to prevent, the lower part through through hole 5 is provided with limited step 7, in 1 lower part of the detection screw rod
It is provided with the positive stop lug boss 8 coordinated with limited step 7.
For the ease of tightening, it is provided in the upper end of the detection screw rod 1 and tightens knob 9.
The utility model so uses：When detecting screw thread hole depth, screwed in by tightening knob 9 by screw rod 1 is detected
Tested part threaded hole, the scale detected on scale 3 can be axially moveable with the variation of screw-in depth, and detection screw rod 1 screws in
During to tested part threaded hole bottom, detection screw rod 1 shows threaded hole actual measurement effective depth with detection scale 3 with credit union.
