Problems solved by technology

Especially in the process of multi-process and repeated circulation of impeller parts, multiple locking and loosening between the daughter board and the mother board are required. At present, the traditional comprehensive The contact method often causes the clamping and positioning accuracy of the impeller parts to fail to meet the process requirements
Processing impeller parts in this way will lead to product size out of tolerance and scrap

Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016] The invention provides a sub-board for quick replacement of impeller parts, one side of the sub-board 1 is fixedly connected with the tooling, the tooling and the impeller parts are clamped together, and the other side of the sub-board 1 is installed in cooperation with the mother board, as shown in FIG. figure 1 As shown, the sub-board 1 is processed with a "ten"-shaped concave surface to form a matching installation surface with the motherboard, that is, four positioning contact surfaces 3. The number is determined by the mounting holes on the motherboard. The verticality of the pull stud 2 is 0.01 mm. The pull studs 2 are evenly distributed around the circumference, and the center of the circle around which the pull studs 2 surround coincides with the center of the sub-board 1 .

[0017] The outer peripheral surface of the sub-board 1 is provid...

Abstract

The invention discloses a quick replacement sub-board for an impeller part. A concave surface is processed in the middle portion of the sub-board to form a mounting surface matched with a mother board. Pop-rivets mounted with the mother board in a matched mode are fixed on the concave surface, the pop-rivets are evenly distributed along the circumference, the center of the circumference which thepop-rivets are along and the center of the sub-board coincide, and the outer circumference of the sub-board is provided with a clamping groove for an external mechanical hand to capture. The quick replacement sub-board can improve the contact rigidity and the positioning precision of the sub-board and the mother board in the process of quick replacement of the impeller part, and the repeated positioning precision of quick replacement of the impeller part is ensured.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a sub-board for quick replacement of impeller parts. Background technique [0002] Impeller parts are key products in aerospace engines. By establishing an automated production line for mass production of impeller parts and using quick changeover technology in the automated production line, the downtime of machine tools can be effectively reduced, the production efficiency of impeller parts can be improved, and the consistency of machining accuracy of impeller parts can be guaranteed. . In the automatic production line of impeller parts, the fast replacement method in the form of daughter board and mother board can be adopted, and the positioning and locking method between daughter board and mother board determines the accuracy of quick replacement. Especially in the process of multi-process and repeated circulation of impeller parts, multiple locking and loosening between the ...
