Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1 and 2, an efficient batch sizing end-cutting auxiliary device for aircraft engine elbow parts comprises an elbow positioning block 1, a sizing slide rail 2, a guide slide block 3, a sizing locking butterfly nut 4, an elbow corner posture-adjusting drive plate 5, an elbow corner posture-adjusting positioning plate 6 and a posture-adjusting drive plate locking screw 7; the elbow corner posture-adjusting fixing disc 6 is fixedly connected to the end-cutting machine body 8; the bent pipe corner posture adjusting and fixing disc 5 is embedded in a rotary guide groove of the bent pipe corner posture adjusting and fixing disc 6, and the bent pipe corner posture adjusting and fixing disc 5 has a rotary degree of freedom in the rotary guide groove of the bent pipe corner posture adjusting and fixing disc 6; the posture adjusting movable disc locking screw 7 is arranged between the bent pipe corner posture adjusting fixed disc 6 and the bent pipe corner posture adjusting movable disc 5; the fixed length slide rail 2 is vertically and fixedly connected to the elbow corner posture adjusting disc 5; the guide slide block 3 is positioned in a linear chute of the fixed-length slide rail 2, a screw 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 is positioned at the other end of the guide slide block 3, the fixed-length locking butterfly nut 4 is screwed and sleeved on the screw, 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 positioning clamping groove is formed in the bent pipe positioning block 1, and the bending section of the bent pipe part 11 is positioned in close fit with the arc positioning clamping groove of the bent pipe positioning block 1.
The one-time use process of the present invention is described below with reference to the accompanying drawings:
in this embodiment, statistics shows that the lengths of 95% of the elbow ends of the aircraft engine do not exceed 100mm, so that the length of the fixed-length slide rail 2 is set to 100mm, and the requirements of positioning and end cutting of most elbow parts can be met.
After the high-efficiency batch sizing end cutting auxiliary device for the aircraft engine elbow parts is installed on an end cutting machine, the sizing locking butterfly nut 4 is unscrewed firstly, so that the elbow positioning block 1 can freely move along the sizing slide rail 2 along with the guide slide block 3 until the elbow positioning block 1 is moved to the set end cutting size position, then the sizing locking butterfly nut 4 is screwed, and the position of the elbow positioning block 1 is fixed.
The bent pipe part 11 needing end cutting is placed into the arc-shaped positioning clamping groove of the bent pipe positioning block 1, so that the bending 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 at the moment, the relative position between the bent pipe part 11 and the bent pipe positioning block 1 is fixed.
