Description

Technical Field

[0001] This utility model belongs to the field of outer ring blade processing technology, specifically relating to a milling processing device. Background Technology

[0002] Milling the outer ring is a crucial process in machining the arc shape of the outer ring blade, ensuring the stability and precision of the part. Currently, when machining the inner arc surface of the outer ring's outer flow channel in the initial stage, the reference surfaces on both sides are not yet wire-cut. This results in a large blank allowance, and the design reference point is located on one side of the inner arc wall. If wire-cutting is performed first, followed by milling on one side, significant dimensional differences and large errors after wire-cutting will occur, impacting production progress and compromising efficiency. Therefore, based on the outer ring blade design drawing and machining process requirements, milling of the inner arc surface of the outer ring's outer flow channel is necessary first. This ensures the arc dimensions and removes excess Pt wire generated during casting. The goal is not only to achieve a qualified shape but also to guarantee a reliable positioning reference during wire-cutting at both ends. To efficiently and safely produce qualified parts, a milling device has been designed for milling the inner arc surface of the outer ring's outer flow channel. Utility Model Content

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] Example

[0013] like Figure 1 , Figure 2 and Figure 3 As shown, the milling device provided in this embodiment includes a base 1, on which a support seat 2 is fixedly installed. The bottom surface of the support seat 2 is fixedly connected to the top surface of the base 1 by bolts. The surface of the support seat 2 is an arc surface that matches the bottom surface of the outer ring blade. In this embodiment, the surface size of the support seat 2 matches the size of the outer ring blade. By matching the arc of the surface of the support seat 2 with the arc of the bottom surface of the outer ring blade, the reference surface positioning of the outer ring blade in the vertical direction is completed after the bottom surface of the outer ring blade is attached to the surface of the support seat 2.

[0014] The support base 2 has reference columns 3 at both ends on the same side, which are closely attached to the side wall of the support base 2. The bottom end of the reference column 3 is fixedly installed on the surface of the base 1. The same side of the outer ring blade is attached to the same cut surface of the two reference columns 3 through the two reference columns 3, so as to complete the reference positioning of the outer ring blade in the horizontal front and rear directions.

[0015] A positioning seat 4 is fixedly installed on the surface of the base 1 near one end of the support seat 2. The top of the positioning seat 4 is rotatably connected to a positioning hook 5 that matches the end of the outer ring blade. When clamping the outer ring blade, the limiting pin 6 is removed first, and the positioning hook 5 is flipped. When the positioning hook 5 is horizontal and facing the support seat 2, the hook connection part of the positioning hook 5 is engaged with the side wall of the end of the outer ring blade, thus completing the reference positioning of the outer ring blade in the horizontal left and right directions.

[0016] The support base 2 is provided with pressure plates 7 on both sides, which are matched with the height of the outer ring blade. The ends of the pressure plates 7 are fixedly connected to the base 1 through support rods 8. The pressure plates 7 are provided with locking screws 9 near the support base 2. The bottom end of the locking screws 9 extends into the base 1 and is threaded into the base 1. The bottom surface of the pressure plates 7 is an arc surface that matches the surface of the outer ring blade. After the outer ring blade is positioned in the vertical, horizontal front-back and horizontal left-right directions, the locking screws 9 are tightened to press the pressure plates 7 downward to clamp the outer ring blade. After clamping, the positioning hooks 5 are flipped upward to move them away from the top milling area. After flipping, the positioning hooks 5 are prevented from flipping into the processing area by inserting the limiting pin 6.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and utility model concepts provided by the present utility model should be covered within the protection scope of the present utility model.
