Abstract

The invention provides a pre-positioning tightening mechanism for arc tenon tooth blades. The pre-positioning tightening mechanism can solve the problems that existing pre-positioning standard is not coincident with a molded surface machining positioning standard, and the blade root machining accuracy is low. The pre-positioning tightening mechanism comprises a base plate which is provided with a positioning mechanism and a tightening mechanism body; the pre-positioning tightening mechanism is characterized in that the positioning mechanism comprises a positioning base, a right convex part is arranged at the top of the positioning base, and a positioning supporting plate used for positioning arc tenon tooth blade root back process lugs is fixedly installed on the bottom face of the right convex part; and the tightening mechanism body comprises a tightening level and a tightening base, the tightening level is rotationally supported to the tightening base, the tightening base is fixedly installed on the base plate and located below the right convex part of the positioning base, the front end of the tightening level is provided with a tightening part upwards cocked to be bent, the back end of the tightening level can be in locked connection with the tightening base, and the tightening part abuts against an arc tenon tooth blade root internal process lug.

Description

technical field [0001] The invention relates to the field of tooling fixtures for blade processing, in particular to a pre-positioning and clamping mechanism for circular-arc mortise-tooth blades. Background technique [0002] With the development of blade processing technology, mortise-toothed blades with very high requirements for the position of the profile relative to the blade root use the blade root process first to process the blade, and then use the blade to position and process the blade surface, and then pre-position the blade. The profile is fixed in a certain position of the square box, and finally the square box is used to locate the process route for processing the blade root. [0003] In the actual processing process, in order to ensure the processing accuracy of the blade root, it is usually required that the pre-positioning adopts the same positioning method as that of the processing profile. The shape characteristics of the arc tenon teeth determine that it...
