Abstract
The utility model discloses a kind of instrument for measuring part inside groove slot size, relate to mechanical measurement field, comprise: mainboard, measuring staff and trip bolt, described mainboard has I-shaped groove and fastening screw nail, mainboard sidewall has square groove, square groove is crossing with I-shaped groove, and fastening screw nail is passed through mutually with I-shaped groove top; Described measuring staff is the rectangular structure of front end buckle, and described measuring staff is put into mainboard I-shaped groove and can be slided; Described trip bolt is screwed in mainboard upper bolt aperture.The utility model achieves slewing parts inside groove slot size detection, solve the problem that existing dimensional measurement class measurer cannot measure aperture inside groove, achieve the accurate measurement of inside groove slot size, improve the accuracy of measurement, improve work efficiency, the measurement for other like parts provides a kind of new method.
Description
Technical field:
The utility model relates to mechanical measurement field, particularly relates to a kind of part inside groove slot dimension measurement tool.
Background technology:
In the slot dimensional measurement of slewing parts inside groove, existing measurement means effectively cannot measure inside groove slot size, slide calliper rule and altimeter can measure endoporus, but the not visible property of the trough for endoporus, gauger directly cannot observe inner case, measuring accuracy is difficult to ensure, measuring method is inconvenient, especially when aperture size is less than the inside groove of 10mm, there is difficult point in the measurement of its slot always, there is no simple and efficient survey instrument, often need to cut open the method that then part uses universal tool microscope to measure, cause part rejection
Traditional measurement method, due to by the restriction of measuring tool sizes, is difficult to be accurately measured inside groove slot size, for production and processing provides reliable measurement data, affects crudy, reduces production efficiency, wastes time and energy.
Summary of the invention
The technical matters that the utility model solves
For existing methodical deficiency, adopt a kind of part inside groove slot dimension measurement tool, accurately measure part inside groove slot size, for processing provides measurement data accurately, and measuring method is easy, shortens non-cutting time, improves production efficiency.
The technical solution adopted in the utility model
A survey instrument for slewing parts inside groove slot size, comprising: mainboard 1, measuring staff 2, trip bolt 3, described mainboard 1 has I-shaped groove and fastening screw nail, I-shaped groove end face and measured hole in piece part end face are fitted, and on mainboard 1, I-shaped groove is support and the gathering sill of measuring staff 2; One end of measuring staff 2 is inserted in mainboard 1 I-shaped groove, and one end is goed deep in the aperture of tested slewing parts in addition, and measuring staff 2 locates slewing parts inside groove by the hook formation that turns back of its front end; Trip bolt 3 is screwed into the fastening screw nail on mainboard 1, fastening measuring staff 2.
Measuring staff 2 distance value turned back between the end face of hook formation and mainboard end face 1 is the slot size of slewing parts inside groove.
Technique effect of the present utility model
Compared with original job operation, use the utility model, measuring staff size is little, can go deep in aperture easily, and in the hook portion energy hook of measuring staff front end and hole, trough is fitted, accurate locating grooves sidewall locations.Then, only need after the end face of mainboard side and hole outer wall is fitted, tighten the locked measuring staff of trip bolt at mainboard top, then this measurer is taken out, according to required accuracy selection, existing slide calliper rule or universal tool-measuring microscope, measure the distance on two sides, gauge both sides, just accurately can obtain part inside groove slot size.
Easily not visible inside groove slot can be transformed into visual measurable size by this instrument.Can according to different size requirements, adjustment measuring staff length.Also can change measuring staff as required, also it can be used in pairs as logical not-go-end, significantly promote batch test efficiency, also solve small-bore inside groove simultaneously and measure a difficult problem, also can be used for the measurement that end face has large chamfering or water jacket slot with the level.The method is convenient, simply, fast, is applicable to extensively promoting.
Accompanying drawing explanation
Fig. 1 is a kind of part inside groove slot of the utility model dimension measurement tool structural representation,
Wherein, 1: mainboard, 2: measuring staff, 3: trip bolt.
Embodiment
In order to better implement the utility model, below in conjunction with Figure of description, the utility model being elaborated, referring to Figure of description 1.
A survey instrument for slewing parts inside groove slot size, comprising: mainboard 1, measuring staff 2, trip bolt 3, described mainboard 1 has I-shaped groove and fastening screw nail, I-shaped groove end face and measured hole in piece part end face are fitted, and on mainboard 1, I-shaped groove is support and the gathering sill of measuring staff 2; One end of measuring staff 2 is inserted in mainboard 1 I-shaped groove, and one end is goed deep in the aperture of tested slewing parts in addition, and measuring staff 2 locates slewing parts inside groove by the hook formation that turns back of its front end; Trip bolt 3 is screwed into the fastening screw nail on mainboard 1, fastening measuring staff 2.
One section of further described measuring staff 2 is inserted mainboard 1, and one end is goed deep in aperture in addition, the slot size of the length value determination inside groove between hook formation end face and mainboard 1 end face that turned back by measurement measuring staff 2.
First clamp-screw 3 is unclamped, measuring staff 2 is stretched in hole in piece part, after touching the right side of inside groove, the left side of mainboard 1 is adjacent to the right side of part, then trip bolt 3 is tightened up.Gauge can carry out choice for use slide calliper rule according to slot precision or the distance of universal tool-measuring microscope to gauge two measuring surface provides size after taking out.
Embodiment one
When measuring aperture and being less than the little valve cover parts of 10 millimeters, in little valve pocket endoporus, there is multiple inside groove.Universal tool-measuring microscope can not be measured, though utilize slide calliper rule and altimeter can go deep in hole, is difficult to observe inner case, cannot realizes the laminating with inside groove end face, cannot Measurement accuracy.Because the singularity of design of part shape, accurately can not ensureing of inside groove slot dimension measurement result, and then cannot ensure crudy; Device described in the utility model can go deep in little valve pocket endoporus smoothly, utilizes hook formation laminating inside groove cell wall, realizes the measurement of inside groove slot size.
Use this instrument:
(1) hand-held survey instrument, gos deep into the position that endoporus needs to measure slot by measuring staff, measuring staff measurement end face and trough wall surface are fitted;
(2) hold measuring staff, slip mainboard, measures end face by mainboard and aperture end face is fitted;
(3) trip bolt on mainboard is tightened, locked measuring staff and mainboard relative position;
(4) take out this instrument, according to accuracy requirement, utilize universal tool-measuring microscope or this instrument of kind of calliper measuring staff and mainboard to measure length between end face, obtain required slot size.
