Embodiment Construction

[0023] See Figure 1 to Figure 5 The jig of the present invention includes a jig bottom plate 1, the center of the jig bottom plate 1 is longitudinally equipped with an airfoil pressing mechanism, and the blade inner annulus positioning mechanism and the blade outer annulus positioning mechanism are respectively installed on the lateral outer sides of the airfoil pressing mechanism. The lateral outer sides of the blade inner ring surface positioning mechanism and the blade outer ring surface positioning mechanism are respectively equipped with a blade process boss pressing mechanism, which positions the processed inner ring of the blade through the blade inner ring surface positioning mechanism and the blade outer ring surface positioning mechanism. The radial surface and the radial surface of the outer ring are compressed by the blade body pressing mechanism and the blade process boss pressing mechanism.

[0024] The airfoil pressing mechanism includes a hinge pressing plate ...

Abstract

The invention provides a clamp used for processing aviation thin-wall blade pitch. By the clamp, the problems of unstability in processing accuracy, long processing time, low efficiency and high cost in an existing method of watering prior to grinding or milling to process the blade pitch can be solved. The clamp is characterized by comprising a clamp baseplate, a blade body compressing mechanism is mounted in the middle of the clamp baseplate longitudinally, a blade inner ring face positioning mechanism and a blade outer ring face positioning mechanism are mounted on two transverse outer sides of the blade body compressing mechanism respectively, and a blade process boss compressing mechanism is mounted on the transverse outer side of each of the blade inner ring face positioning mechanism and the blade outer ring face positioning mechanism. An inner ring radial face and an outer ring radial face, which are already processed well, of a blade are positioned by the blade inner ring face positioning mechanism and the blade outer ring face positioning mechanism and compressed by the blade body compressing mechanism and the blade process boss compressing mechanism.

Description

technical field [0001] The invention relates to the field of production tooling for aviation thin-wall blades, in particular to a fixture for processing the pitch of aviation thin-wall blades. Background technique [0002] Most aviation thin-walled blades use titanium alloy materials. Due to the blade body structure and material properties, the cutting performance of the blades is poor and the processing is easy to deform. The distance between the inner and outer rings of this type of blade is an important assembly dimension, and its surface quality and machining accuracy are very high. Generally, the pitch of such blades is mostly processed by the method of "pouring square box-grinding / milling". This method needs to position the blade body in the square box, then pour the alloy, and wait for the alloy in the square box to cool and solidify. , and then position and clamp the square box on the grinder / milling machine table, and then process the pitch surface. This method ha...
