Description
Technical field
The present invention relates to measure measurer field, and in particular to screwed hole group position degree inspection measurer.
Background technology
In Production of Crankshaft, the requirement of bent axle screwed hole group position degree is very high, and the detection of bent axle screwed hole is often adopted
It is that object detection methods detection is sat in height gauge or use three.All there is detection efficiency lowly in both modes, to inspection
Person's skill set requirements problem high, therefore be not suitable for high-volume inspection and machining center operator's self-inspection.
The content of the invention
Technical problem：A kind of simple structure, behaviour are provided it is an object of the invention to overcome the inspection inconvenience of general measurer
Make the bent axle screwed hole group position degree inspection measurer of convenient, high precision.
Technical scheme：To achieve the above object, a kind of bent axle screwed hole group position degree inspection measurer of the invention is provided such as
Lower technical scheme：The inspection measurer is included by positioning sleeve, the measurement apparatus of alignment pin, bushing and latch composition；Wherein,
Along the dowel hole and installation bushing that installation alignment pin is provided with the circumference of same Radius in the plane of positioning sleeve
The axial direction of bush hole, dowel hole and bush hole is axially in parallel with positioning sleeve, and dowel hole has 2 axles for being symmetrical in positioning sleeve
The heart is arranged on the circumference of same Radius, and alignment pin is positioner with positioning sleeve, and it is fixed that alignment pin is fitted into perpendicular to positioning sleeve
Position pin-and-hole, alignment pin uses interference fit with the dowel hole on positioning sleeve；The bush hole for installing bushing is symmetrical in positioning sleeve
Axle center is arranged on the circumference of same Radius, and the stage casing of latch is located in bushing, and latch coordinates to check screwed hole with positioning sleeve
Position degree.
Wherein：
Described bushing has multiple, and positioning sleeve uses interference fits, is convenient for changing bushing with bushing.
Described alignment pin uses interference fit with positioning sleeve.
Described latch, its front end uses screw thread guide frame, and middle part is cylinder inspection position, and rear end is antiskid knot
Structure.
Positioning sleeve uses tube-in-tube structure, is enclosed within detected bent axle.
Beneficial effect：Compared with prior art, bent axle screwed hole group position degree inspected number tool beneficial effect of the invention is：
Measurer is installed conveniently in use in producing detection, and positioning sleeve is directly placed on screwed hole group end, and positioning is convenient, and latch is smoothly screwed into
Threaded hole position meet design requirement.Simple structure of the present invention, it is easy to operate, it is practical strong.
Brief description of the drawings
Fig. 1 is planar structure schematic diagram of the invention.
Fig. 2 is Figure 1A-A to sectional view.
Wherein have：Positioning sleeve 1, alignment pin 2, latch 3, bushing 4.
Specific embodiment
A kind of bent axle screwed hole group position degree inspection measurer of the invention, including a positioning sleeve, two alignment pins are multiple
Bushing and latch.Bushing uses interference fits with positioning sleeve, and positioning sleeve is interference fit with alignment pin, and positioning sleeve is placed on bent axle
Screwed hole group end；Measurer is positioned by two alignment pins and positioning sleeve.Latch insertion bushing is screwed into tested screwed hole.
Particularly, the positioning sleeve uses fabricated structure rather than integral structure, bushing to match somebody with somebody using transition with positioning sleeve
Close, wear and tear conveniently replaced, and can more resleeve and latch be to measure the bent axle screwed hole group position degree of different series
It is no to meet design requirement.
Specific embodiment of the invention is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1, a kind of bent axle screw thread
Hole group inspection measurer includes positioning sleeve 1, alignment pin 2, latch 3 and bushing 4.
Along the dowel hole and installation that installation alignment pin 2 is provided with the circumference of same Radius in the plane of positioning sleeve 1
The axial direction of the bush hole of bushing 4, dowel hole and bush hole is axially in parallel with positioning sleeve 1, and dowel hole has 2 to be symmetrical in calmly
The axle center of position set 1 is arranged on the circumference of same Radius, and alignment pin 2 is positioner with positioning sleeve 1, and alignment pin 2 is perpendicular to fixed
Position set 1 fits into dowel hole, and alignment pin 2 uses interference fit with the dowel hole on positioning sleeve 1；The bushing of bushing 4 is installed
Hole is symmetrical in the axle center of positioning sleeve 1 and is arranged on the circumference of same Radius, and the stage casing of latch 3 is located in bushing 4, latch 3 with it is fixed
Position set 1 coordinates to check threaded hole position.
When the present invention is used：
（1）Ensure all part assembling site anteseptic no-sundries of screwed hole group inspection measurer,
（2）During alignment pin and bushing fitted into positioning sleeve successively,
（3）In crankcase scavenged screwed hole group and screwed hole group end surfaces the debris such as iron filings, it is ensured that screwed hole group and its end face
Clean no-sundries,
（4）Positioning sleeve locating surface is wiped with clean cloth, it is ensured that the clean no-sundries of locating surface,
（5）Positioning sleeve is gently placed on screwed hole group end, alignment pin is directed at dowel hole,
（6）Latch is threaded into hole, such as screwed hole can smoothly be screwed into latch, then the threaded hole position meets design and wants
Ask, on the contrary then there is deviation in position degree, does not meet design requirement；Remaining screwed hole is checked successively.
