Description
Technical field
It the utility model is related to measurement measurer field, and in particular to screwed hole group position degree examines 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 height gauge or sits object detection method detection using three.It is low detection efficiency to be all present in both modes, to examining
The problem of person's skill set requirements are high, therefore be not suitable for high-volume inspection and machining center operator's self-test.
The content of the invention
Technical problem：The purpose of this utility model is the inspection inconvenience for overcoming general measurer and provides a kind of structure letter
The bent axle screwed hole group position degree single, easy to operate, precision is high examines measurer.
Technical scheme：To achieve the above object, a kind of bent axle screwed hole group position degree of the present utility model examines measurer to carry
For following technical scheme：The inspection measurer is included by positioning sleeve, the measurement apparatus of alignment pin, bushing and latch composition；Wherein,
Served as a contrast in the plane of positioning sleeve along dowel hole and installation that installation alignment pin is provided with the circumference of same Radius
The axial direction of the bush hole of set, dowel hole and bush hole and positioning sleeve it is axially in parallel, dowel hole has 2 to be symmetrical with positioning sleeve
Axle center be arranged on the circumference of same Radius, alignment pin and positioning sleeve be positioner, and alignment pin is perpendicular to positioning sleeve assembling
Enter dowel hole, alignment pin is with the dowel hole on positioning sleeve using interference fit；The bush hole of installation bushing is symmetrical with positioning
The axle center of set is arranged on the circumference of same Radius, and the stage casing of latch is located in bushing, and latch coordinates with positioning sleeve to examine spiral shell
Pit position degree.
Wherein：
Described bushing has multiple, and positioning sleeve and bushing use interference fits, are convenient for changing bushing.
Described alignment pin is with positioning sleeve using interference fit.
Described latch, its front end use screw thread guide frame, and position is examined in middle part for cylinder, and rear end is antiskid knot
Structure.
Positioning sleeve uses tube-in-tube structure, is enclosed on detected bent axle.
Beneficial effect：Compared with prior art, there is bent axle screwed hole group position degree inspected number of the present utility model benefit to imitate
Fruit is：Measurer is loaded conveniently in use during production detects, and positioning sleeve is directly placed on screwed hole group end, and positioning is convenient, and latch is suitable
The threaded hole position that profit is screwed into meets design requirement.The utility model is simple in construction, easy to operate, practical strong.
Brief description of the drawings
Fig. 1 is planar structure schematic diagram of the present utility model.
Fig. 2 is Figure 1A-A to sectional view.
Wherein have：Positioning sleeve 1, alignment pin 2, latch 3, bushing 4.
Embodiment
A kind of bent axle screwed hole group position degree inspection measurer of the present utility model, including a positioning sleeve, two alignment pins,
Multiple bushings 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, and bushing is matched somebody with somebody with positioning sleeve using transition
Close, abrasion is 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 present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1, a kind of bent axle
Screwed hole group examines measurer to include 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 with 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 is with the dowel hole on positioning sleeve 1 using interference fit；The bushing of bushing 4 is installed
The axle center that hole is symmetrical with positioning sleeve 1 is arranged on the circumference of same Radius, and the stage casing of latch 3 is located in bushing 4, and latch 3 is with determining
Position set 1 coordinates to examine threaded hole position.
When the utility model uses：
（1）Ensure that the screwed hole group examines all part assembling site anteseptic no-sundries of measurer,
（2）Alignment pin and bushing are fitted into positioning sleeve successively,
（3）In crankcase scavenged screwed hole group and the debris such as iron filings of screwed hole group end surfaces, it is ensured that screwed hole group and its
The clean no-sundries in end face,
（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 to screwed hole group end, alignment pin is directed at dowel hole,
（6）Latch is threaded into hole, as the screwed hole can smoothly be screwed into latch, then the threaded hole position meets design
It is required that it is on the contrary then deviation occurs in position degree, do not meet design requirement；Remaining screwed hole is examined successively.
