Embodiment Construction

[0038] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0039] A preferred embodiment of the present invention provides a blade tenon grinding jig, which is used for quickly positioning and clamping the blade to be processed, so as to meet the technical requirements of the dimensional tolerance and shape tolerance after the blade tenon is ground. refer to figure 1 , the blade to be processed in this embodiment casts a square box 20 at its blade pot and blade back for auxiliary positioning during clamping. refer to Figure 2 to Figure 4 In this embodiment, the blade tenon grinding jig includes a bottom plate 10 that supports positioning. The upper surface of the bottom plate 10 is used as a mounting surface for installing the blade to be processed....

Abstract

The invention discloses a blade tenon grinding fixture. The blade tenon grinding fixture comprises a baseplate achieving a support positioning effect; the upper surface of the baseplate serves as a mounting surface for mounting a blade to be machined; square boxes for auxiliary positioning are cast at a blade basin and a blade back of the blade to be machined; the mounting surface of the baseplate is a horizontally inclined angle surface; a positioning mechanism for clamping and positioning the square boxes is arranged on the mounting surface; and the baseplate is additionally provided with a drainage mechanism for guiding cooling liquid to a tenon of the positioned blade to be machined to reduce the grinding heat. As the mounting surface of the baseplate is designed as the horizontally inclined angle surface, the tenon symmetry center of the blade is conveniently adjusted in the machining process, and the prolonging of the service life of a formed grinding wheel is facilitated; and the drainage mechanism is arranged on the baseplate, so that the grinding heat is reduced, the quick positioning and clamping requirements are satisfied, the dimensional tolerance and the geometric tolerance of the grinded blade tenon reach the technical requirements, the reliability in the machining process is improved, and the service life of the formed grinding wheel for grinding is prolonged.

Description

technical field [0001] The invention relates to the field of aeroengine blade processing, in particular to a blade tenon grinding jig. Background technique [0002] In the existing field of aero-engine blade processing, it is necessary to grind the tenon part of the blade to meet the technical requirements of dimensional tolerance and shape tolerance. [0003] In the past, the positioning and clamping of the surface of the fixture are realized by plane, round hole, outer cylindrical surface, tapered hole and general clamping device. If two or more blades need to be positioned and clamped on the same grinding jig at the same time, it will result in many positioning and clamping structures, long production and manufacturing cycle, high processing difficulty, complex overall structure and large external dimensions. At the same time, when producing products, the operation is cumbersome, the processing preparation time is long, and the positioning operation is inconvenient. The...
