Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of helicitic texture component parameter measurement mechanism, is widely used in the indirect measurement of the measurement of bolt group degree of tightness, the measurement of bolt group textural association part snap-in force, nut or helicitic texture part shift motion amount etc.
Background technology
The stroke measuring device research that is applied at present the bolt group structural member that the scene of electric power charging equipment uses belongs to blank field at home and abroad, the stroke measurment technology of most bolt group structural member is only applied to the experimental facilities of the travel parameters collection in laboratory, is not applicable to the stroke measuring device of power equipment GB bolt group structural member at present.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of helicitic texture component parameter measurement mechanism, has solved the problem of the stroke measuring device that is not applicable to power equipment GB bolt group structural member in prior art.
The technical solution of the utility model is as follows:
The top of body is provided with helicitic texture, in body, be provided with carriage release lever, the top of carriage release lever is provided with magnet and stretches out body, the bottom of carriage release lever is connected with one end of lever, the other end of lever is connected with the bottom of movable depression bar, the top connection metal plate of movable depression bar, straingauge is pasted on sheet metal, and the slotted line of drawing of straingauge is drawn body.
Described helicitic texture is, the top of body is provided with groove, and groove inwall arranges internal thread, and internal thread and MUT module under test external thread match.
Described helicitic texture is, the top of body arranges projection, and the outer wall of projection arranges external thread, and external thread and MUT module under test internal thread match.
Described carriage release lever top magnet touches mutually with MUT module under test.
Described sheet metal is elastic metal sheet.
Described body top is provided with the fixed orifice being connected with MUT module under test.
The advantageous effect of the utility model patent is as follows:
1, push rod is with magnet head directly by being pressed in nut structure or threaded structural member metal surface, and when surface occurs to move up and down, lever can be pressed straingauge and produces to be bent to and answer sheet resistance to change, and its principal feature is that measuring accuracy is high; It is better, applied widely that straingauge is measured sealing property simultaneously.
2, helicitic texture can be that groove can be also projection, is applicable to different screw thread MUT module under tests.
3, carriage release lever magnet and immediate roof be on tested nut structure or threaded structural member surface, and when surface rotates while axially moving up and down, carriage release lever can and then move.
4, body arranges fixed orifice, can insert pin or screw and reinforce fixing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Application Example structural representation of the present utility model.
In figure, 1, carriage release lever, 2, lever, 3, movable depression bar, 4, sheet metal, 5, straingauge draws slotted line, 6, fixed orifice, 7, body.
Embodiment
With reference to accompanying drawing, in conjunction with specific embodiments, be described in detail as follows.
Embodiment
As shown in Figure 1, the top of body 7 is provided with groove, and groove inwall arranges internal thread, and internal thread and MUT module under test external thread match.In body 7, be provided with carriage release lever 1, the top of carriage release lever 1 is provided with magnet and stretches out body, magnet contacts with MUT module under test, the bottom of carriage release lever 1 is connected with one end of lever 2, the other end of lever 2 is connected with the bottom of movable depression bar 3, the top of movable depression bar 3 connects elastic metal sheet 4, and straingauge is pasted on elastic metal sheet 4, and the slotted line 5 of drawing of straingauge is drawn body; Described body top is provided with the fixed orifice 6 being connected with MUT module under test, and fixed orifice 6 inserts pin or screw is reinforced fixing.
Embodiment 2
Described helicitic texture is, the top of body arranges projection, and the outer wall of projection arranges external thread, and external thread and MUT module under test internal thread match.Other structure is with embodiment 1.
First fixing by helicitic texture and the MUT module under test rotation on body top, and prevent rotation and come off at fixed orifice erection bolt pin or screw, when nut structure part or threaded structural member occur when loosening or mobile, thereby carriage release lever transmission stresses on movable depression bar to transmission levers, movable depression bar is pressed the straingauge being arranged on elastic sheet metal and is bent and cause resistance change.By straingauge extension line, measure and just can record resistance change, indirectly understand nut structure part or threaded structural member shift motion amount.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on technical solutions of the utility model basis, within all belonging to protection domain of the present utility model.
