Background technology
In product mechanical processing process, the quality control of the product important step that is absolutely necessary.The accuracy of product geometric parameter check is again the important means that guarantees product quality.Blade is a very important class part in aeromotor part, and the performance of engine is played to key effect.When swallow-tail form blade tenon is detected, a kind of is to detect with projecting method, testing process more complicated, and cannot realize on-line measurement, and will reduce production efficiency like this, increase product processing cost; Another kind is to detect by go-no go gauge method, easy to operate, can realize on-line measurement, but whether can only judge tenon overall dimensions qualified, cannot detect tenon width actual value.
Summary of the invention
The technical matters solving
The problem existing for solving prior art, the utility model proposes a kind of swallow-tail form blade tenon fixed point width detecting.
Technical scheme
The technical solution of the utility model is:
Described a kind of swallow-tail form blade tenon fixed point width detecting, is characterized in that: comprise base, positioning contact, movable gauge head, measuring staff, guide pin bushing, spring, meter; On base, be fixed with locating piece, locating piece is in swallow-tail form blade tenon bottom, for swallow-tail form blade tenon is located, positioning contact is fixed on base one side, positioning contact is for by the first side of swallow-tail form blade tenon location, and locating piece and positioning contact position coordinate positioning contact is withstood on a side measured point of swallow-tail form blade tenon; Guide pin bushing is fixed on base opposite side, and there is step through-hole at guide pin bushing center; Measuring staff is Step Shaft, and measuring staff coordinates with guide pin bushing concentric gap, between measuring staff step surface and guide pin bushing central through hole step surface, has Compress Spring; Measuring staff head is coaxially fixed with movable gauge head, and movable gauge head central axis and location gauge head central axis are in same plane; Guide pin bushing middle part is provided with driving lever, and driving lever coordinates with measuring staff, can drive measuring staff to move vertically, and measuring staff end is fixedly connected with meter.
Beneficial effect
The advantage of the utility model design is: this measuring tool overcome projection detect can not on-line measurement and go-no go gauge detect the shortcoming that cannot measure actual value, be applicable to detect all dove-tail form blade tenons fixed point width actual values, and can realize on-line measurement.Shorten the product manufacturing cycle, improved production efficiency, reduced cost of goods manifactured.The measuring staff automatic rollback mechanism forming by driving lever and spring in measuring tool design is skillfully constructed, and makes measuring tool detect position motion flexibly, easy to operate while measuring clamping, detects accurately.

Embodiment
Below in conjunction with specific embodiment, the utility model is described:
With reference to accompanying drawing 1, the swallow-tail form blade tenon fixed point width detecting in the utility model, comprises base 1, positioning contact 4, movable gauge head, measuring staff 5, guide pin bushing 6, spring 7, driving lever 8, dial gauge 12.
Take base 1 as main member, and at base inner face fixed installation locating piece 2, locating piece is in swallow-tail form blade tenon bottom, for swallow-tail form blade tenon is located.At 2 adapter sleeves 3 of the parallel installation of chassis left side, and by adapter sleeve, positioning contact 4 is installed, wherein adapter sleeve and base clearance fit, change different length positioning contact thereby can dismantle as required, and lock-screw 13 can be fixed adapter sleeve 3.Positioning contact is for by the first side of swallow-tail form blade tenon location, and locating piece and positioning contact position coordinate on the measured point of a side that makes positioning contact withstand on swallow-tail form blade tenon.
At base right side fixed installation guide pin bushing 6, use screw 14 lockings.There is step through-hole at guide pin bushing center; Measuring staff is Step Shaft, and measuring staff coordinates with guide pin bushing concentric gap, and gap is not more than 0.005mm.Between measuring staff step surface and guide pin bushing central through hole step surface, there is Compress Spring 7.Measuring staff head is coaxially fixed with movable gauge head, and movable gauge head central axis and location gauge head central axis are in same plane.
Guide pin bushing middle part is provided with fixed block 9, and driving lever and fixed block are rotatably assorted by straight pin, and driving lever lower end coordinates with measuring staff, by stirring driving lever, can drive measuring staff to move vertically.
Measuring staff its right end face and dial gauge 11 laminatings, measuring staff athletic meeting changes dial gauge reading, and 10 pairs of dial gauges of use table folder screw are locked.
With reference to accompanying drawing 3 and accompanying drawing 4, tested blade tenon requires the actual value of the upper size a of etection theory height L, and this installs corresponding method is the method that adopts the relative measurement of standard component his-and-hers watches, realizes the object of directly measuring tested blade tenon fixed point width a.
During measurement, adopt the standard component of Fig. 4, standard component is placed on measuring tool after the zeroing of measuring tool dial gauge, and measuring tool is positioned to the blade tenon position on production line, and the reading by table goes to judge that tested fixed point width is whether in required margin tolerance.Locate with 2 pairs of blade tenon bottoms of locating piece at measuring tool localization part one place, and another place, with 4 pairs of tenons of two stationary positioned contacts, one side location, by controlling positioning contact to the distance between locating surface, guarantees that positioning contact is fixed on tenon measured point.Between the movable gauge head of opposite side and dial gauge, by spring, be connected with measuring staff 5, under spring-force driven dual, promoting measuring staff and gauge head moves to measured direction, the measuring staff other end is connected with dial gauge, its motion changes dial gauge reading, observe its reading whether in required margin tolerance, judge that thus whether tested fixed point width is qualified.In measuring staff right-hand axis, process two planes, groove on driving lever 8 is clamped in measuring staff plane, utilize lever principle, stir driving lever left, driving lever drives measuring staff to connect detection position and moves right, measuring tool can be positioned blade tenon smoothly like this, unclamps after driving lever, and measuring point is subject to spring pressure to realize measuring ability to left movement automatically.Two fixedly gauge head by adapter sleeve, be connected with base, while needing, can be easier to change different length contact; The guide pin bushing that right side is connected with movable contact also can move left and right, and adjusts to while needing position and is locked by screw.Can meet so different big and small blade tenon width are measured.
