Abstract
The invention provides a detection apparatus of an arc tenon-tooth blade-root molded line and an intermediate molded line. When current molded line detection is performed on a test piece, the detection is not accurate; detection cost is high; operation is complex and there are many other problems. By using the detection apparatus of the invention, the above problems can be solved, blade detection production efficiency can be substantially increased and production cost can be reduced. The apparatus is characterized in that: the apparatus comprises a tooth type detection templet and a blade-root top tight device; the tooth type detection templet is provided with a detection contour groove; the blade-root top tight device is installed on a lower part of the tooth type templet.
Description
Technical field
The present invention relates to tenon tooth class blade root molded lines detection range, be specially the pick-up unit of circular arc tenon tooth blade root molded lines and intermedium molded lines.
Background technology
The tenon tooth blade root is the highest position of blade processing precision; And the detection of circular arc tenon tooth blade root molded lines also becomes the difficult point of detection; Detection method commonly used at present is the test piece that is complementary with cutter processing of processing tenon tooth and tenon tooth blade root molded lines earlier; Thereby test piece detects through adopting detection meanss such as enlarged drawing, Wan Guangxian or three-dimensional that its molded lines is whether qualified judges whether designing requirement of blade; Its shortcoming is: the data of gathering when it detects come from test piece but not blade to be measured self; Because there is error in the trade union that adds of test piece, thereby can not be equal to the testing result for blade itself fully for the testing result of test piece, can not be as the whether qualified foundation of this batch of interpretation blade; In addition, adopt methods such as enlarged drawing, Wan Guangxian or three-dimensional detection that test piece is detected, it detects, and cost is high, detecting operation is loaded down with trivial details, is prone to cause produce and pauses, and influences production efficiency; In addition, adopt test piece to detect, the tenon tooth molded lines test piece that needs processing regularly to be used to detect, production cost is high.
Summary of the invention
To the problems referred to above; The invention provides the pick-up unit of circular arc tenon tooth blade root molded lines and intermedium molded lines; It can solve existing through test piece being carried out exist when molded lines detects the detection out of true, detect problems such as cost height, complex operation, and can improve blade detection production efficiency greatly, reduce production costs.
Its technical scheme is such, it is characterized in that: it comprises that flute profile detects model and blade root holding device, and said flute profile detects to have on the model and detects the profile groove, and the bottom of said flute profile model is equipped with said blade root holding device.
It is further characterized in that: the profile of said detection profile groove is by the largest enveloping surface and the setting of detection tolerance value of blade root molded lines, blade root intermedium molded lines;
The bottom that said profile of tooth detects model is clipped between left fixed head and the right fixed head, has rectangular through slot on said left fixed head and the right fixed head, and said blade root holding device is installed in the rectangular through slot of said left fixed head and right fixed head;
Said blade root holding device comprises mobile screw and latch segment; Said latch segment passes through bolt in the groove bottom of said rectangular through slot; The bottom of said mobile screw is threaded through sunk screw with said latch segment; Have unthreaded hole on the baseplane of said flute profile detection model, said mobile screw passes said unthreaded hole.
Beneficial effect of the present invention is: it can directly carry out the detection of molded lines to the tenon tooth blade root; The tenon tooth blade root of blade to be detected directly is inserted in the detection profile groove of detection model of the present invention; Whether through the blade root holding device flute profile workplace of tenon tooth blade root is fitted with the corresponding Design Orientation face that detects the profile groove, adhering to specification with the gap width that detects the profile groove face with each profile of tooth non-working surface of clearance gauge inspection gets final product, and its testing result is true and reliable; Easy to detect quick; Can realize the detection of blade 100%, improve detection efficiency greatly, reduce production cost.
