Background technology
In mechanical processing and other field, often there is same specification internal thread, but there are many different depth the case where, such as
The cylinder block and head of engine, babinet of gearbox etc. typical part.It is measured with the method for touch or step according to traditional
The depth of thread, by taking M8-6H as an example, if there is 10 kinds of different depth, then 10 gauges are just needed when fathoming,
Field management is very inconvenient, and operator is easy puzzlement, and cannot get specific depth data, can only probably judge the depth of thread
It is whether qualified, judge that inaccuracy, low precision can not guarantee product quality, influences using effect.
Utility model content
For the above situation, to overcome the defect of the prior art, the purpose of the utility model to be just to provide a kind of vernier calliper
Ruler formula depth of thread cubing can effectively solve the different measurement of the same specification depth of thread, ensure product quality and using effect
The problem of.
The technical solution that the utility model solves is to utilize vernier caliper principle, go side screw thread gauge head, not-go-end screw thread gauge head
It with measuring rod fixing assembling, is rotated relative to fixed main scale dial drum, axial motionless, the tested part when being screwed into tested threaded hole
Surface compression slides the axial movement of vernier graduation cylinder, to directly read the depth actual value of tested threaded hole, accordingly, this practicality
Novel technical solution is, including go side screw thread gauge head, not-go-end screw thread gauge head, fixed main scale dial drum, sliding vernier graduation cylinder,
Compressed spring, measuring rod and knob, not-go-end screw thread gauge head and go side screw thread gauge head are attached separately to the both ends of measuring rod, measuring rod
On fixed sliding vernier graduation cylinder is housed with one heart, the fixation main scale equipped with concentric fit relative rotation outside sliding vernier graduation cylinder
Dial drum is equipped with concentric compressed spring between measuring rod and sliding vernier graduation cylinder on measuring rod, stretches out fixed main scale and carves
Degree cylinder is connected on the measuring rod of one end with not-go-end screw thread gauge head equipped with knob, measuring rod and fixed main scale dial drum, sliding vernier
Dial drum concentric fit constitutes the relative rotation structure of measuring rod and fixed main scale dial drum, fixed main scale dial drum and sliding
Vernier graduation cylinder concentric fit, constitutes the structure that slides axially of sliding vernier graduation cylinder, compressed spring, fixed main scale dial drum and
Vernier graduation cylinder concentric fit is slided, fixed main scale dial drum is constituted and slides the driving knot in axial sliding between vernier graduation cylinder
Structure, fixed main scale dial drum, to the display port slided vernier graduation and shown is provided with, slide the outer wall upper edge of vernier graduation cylinder along long
Length constitutes the depth of thread and measures display structure to the graduated scale matched with display port is carved with.
The utility model is simple in structure, novel and unique, manufacture easy to produce, easy to install and use, and effect is good, effectively solves
The measurement problem of internal thread hole depth has very strong actual application value, economic and social benefit notable.
Description of the drawings
Fig. 1 is the structural front view of the utility model;
Fig. 2 is the cross-section structure front view of the utility model.
Specific implementation mode
It elaborates to specific embodiment of the present utility model below in conjunction with attached drawing and particular condition in use.
As shown in Figure 1, 2, a kind of vernier caliper type depth of thread cubing of the utility model, including go side screw thread gauge head 7, only
Hold screw thread gauge head 1, fixed main scale dial drum 6, sliding vernier graduation cylinder 5, compressed spring 4, measuring rod 2 and knob 3, not-go-end screw thread
Gauge head 1 and go side screw thread gauge head 7 are attached separately to the both ends of measuring rod 2, and fixed sliding vernier is housed with one heart on measuring rod 2 carves
Cylinder 5, the fixation main scale dial drum 6 relatively rotated equipped with concentric fit outside sliding vernier graduation cylinder 5 are spent, measuring rod 2 and sliding are swum
Concentric compressed spring 4 is housed between indexing cylinder 5 on measuring rod 2, fixed main scale dial drum 6 and not-go-end screw thread gauge head are stretched out
Knob 3 is housed, measuring rod 2 and fixed main scale dial drum 6, sliding vernier graduation cylinder 5 are matched with one heart on the measuring rod 2 of 1 connected one end
It closes, constitutes the relative rotation structure of measuring rod 2 and fixed main scale dial drum 6, fixed main scale dial drum 6 and sliding vernier graduation cylinder
5 concentric fits constitute the structure that slides axially of sliding vernier graduation cylinder 5, compressed spring 4, fixed main scale dial drum 6 and sliding trip
5 concentric fit of indexing cylinder constitutes the driving structure in axial sliding between fixed main scale dial drum 6 and sliding vernier graduation cylinder 5,
Fixed main scale dial drum 6, to the display port 8 slided vernier graduation and shown is provided with, slides the outer wall upper edge of vernier graduation cylinder 5 along long
Length constitutes the depth of thread and measures display structure to the graduated scale 9 matched with display port 8 is carved with.
In order to ensure using effect and easy to use,
The installation taper shank diameter of the not-go-end screw thread gauge head 1 and go side screw thread gauge head 7 is less than the diameter of measuring rod 2.
The variable-diameter structure of different-diameter is constituted between the not-go-end screw thread gauge head 1 and measuring rod 2.
There is pilot hole 10 on the outer wall of the fixation main scale dial drum 6.
When the utility model is used, when measuring the depth of thread, left hand holds fixed main scale dial drum, makes graduated scale direction
Operator, right hand rotation knob, finger tip screw thread gauge head, which screws in, to be tested in threaded hole, and depth value is read, and arbitrarily can also directly be twisted
On earth, it presses afterwards scale face steering operation person;When measuring common-depth, gauge head is directly inserted into measured bore, is read deep
Angle value.The case where measured surface is not easy to see measured hole is encountered, dial drum can be compressed into cubing a distance with left hand,
Equal gauge heads unclamp again after entering measured surface, very easy to use, measure quick and precisely, and work efficiency is high, through applying on the spot and
Test, high certainty of measurement, resolution ratio reach 0.1mm, and it is poor effectively to overcome original thread measurement accuracy, can not guarantee product quality, shadow
Product quality is rung, the measurement of various different depth screw threads is applicable to, is the innovation in depth of thread measuring apparatus, economy and society
It can remarkable benefit.
