Currently, three working procedures, namely scribing, end cutting and end flattening, are usually required for pipe end machining of an aero-engine bent pipe part. In the scribing process, the special fixture or the universal length measuring tool is mainly relied on, and the pipe end positions are visually observed to scribe the pipe branch by branch. In the end cutting step, visual alignment of the tubes is required for each tube during gripping. In the butt process, it is also necessary to visually process the end surface of the pipe to the scribing position.
When the pipe end machining method is adopted, a large margin is reserved when a pipe is cut, and the pipe end machining precision is guaranteed through end trimming at the subsequent step, and as three working procedures of scribing, end cutting and end trimming are manually relied on for visual alignment, the pipe end machining precision and batch identity of bent pipe parts of the aero-engine are difficult to guarantee, and the batch production machining efficiency is low.

Detailed Description
The invention will now be described in further detail with reference to the drawings and to specific examples.
As shown in fig. 1 and 2, the high-efficiency batch sizing and end cutting auxiliary device for the bent pipe parts of the aeroengine comprises a bent pipe positioning block 1, a sizing slide rail 2, a guide slide block 3, a sizing locking butterfly nut 4, a bent pipe corner gesture adjusting moving disc 5, a bent pipe corner gesture adjusting disc 6 and gesture adjusting moving disc locking screws 7; the bent pipe corner gesture adjusting fixed disc 6 is fixedly connected to the end cutting machine body 8; the bent pipe corner gesture adjusting moving plate 5 is embedded in a rotary guide groove of the bent pipe corner gesture adjusting fixed plate 6, and the bent pipe corner gesture adjusting moving plate 5 has a rotary degree of freedom in the rotary guide groove of the bent pipe corner gesture adjusting fixed plate 6; the gesture adjusting moving plate locking screw 7 is arranged between the elbow corner gesture adjusting fixed plate 6 and the elbow corner gesture adjusting moving plate 5; the fixed-length sliding rail 2 is vertically and fixedly connected to the elbow corner gesture adjusting movable disc 5; the guide slide block 3 is positioned in a linear chute of the fixed-length slide rail 2, a screw rod is fixedly connected to the guide slide block 3, the bent pipe positioning block 1 is fixedly connected with one end of the guide slide block 3, the screw rod is positioned at the other end of the guide slide block 3, the fixed-length locking butterfly nut 4 is sleeved on the screw rod in a threaded manner, and the fixed-length slide rail 2 is positioned between the bent pipe positioning block 1 and the fixed-length locking butterfly nut 4; an arc-shaped positioning clamping groove is formed in the bent pipe positioning block 1, and the bent section of the bent pipe part 11 is positioned with the arc-shaped positioning clamping groove of the bent pipe positioning block 1 through close fit.
The following describes a one-time use procedure of the present invention with reference to the accompanying drawings:
in the embodiment, the statistics shows that the length of the bent pipe end of the aeroengine is not more than 100mm, so that the length of the fixed-length sliding rail 2 is set to be 100mm, and the positioning and end cutting requirements of most bent pipe parts can be met.
After the high-efficiency batch sizing end cutting auxiliary device for the aeroengine bent pipe parts is mounted on an end cutting machine, the sizing locking butterfly nut 4 is unscrewed, so that the bent pipe positioning block 1 can freely move along the sizing sliding rail 2 along with the guide sliding block 3 until the bent pipe positioning block 1 is moved to a set end cutting size position, and then the sizing locking butterfly nut 4 is screwed, so that the position of the bent pipe positioning block 1 is fixed.
The bent pipe part 11 needing to be cut is placed into the arc-shaped positioning clamping groove of the bent pipe positioning block 1, so that the bent section of the bent pipe part 11 is tightly attached to the arc-shaped positioning clamping groove of the bent pipe positioning block 1, and the relative position between the bent pipe part 11 and the bent pipe positioning block 1 is fixed. If there is the cutting end interference when installing elbow part 11, can be in order to avoid interfering through rotatory elbow part 11, specifically unscrew the attitude adjustment movable plate locking screw 7 earlier, make elbow corner attitude adjustment movable plate 5 can freely rotate in the gyration guide groove of elbow corner attitude adjustment fixed plate 6, after elbow part 11 avoids interfering the position, screw attitude adjustment movable plate locking screw 7 again can, at this moment elbow corner attitude adjustment movable plate 5 and elbow corner attitude adjustment fixed plate 6 between relative position be fixed.
After the positioning of the bent pipe part 11 is completed, the end cutting machine clamping valve 9 is started to clamp the first straight section of the bent pipe part 11, and then the end cutting machine saw blade 10 can be started to complete end cutting processing. The process is repeated, and the high-efficiency batch fixed-length end cutting of the bent pipe parts of the aero-engine can be realized.
The embodiments are not intended to limit the scope of the invention, but rather are intended to cover all equivalent implementations or modifications that can be made without departing from the scope of the invention.
