Description

Technical Field

[0001] The present invention relates to the technical field of turbine processing, and particularly to the machine tools for the production line of working blades of aviation power turbines. Background Art

[0002] The blades used in aviation power turbines are socketed combined blades. Due to the high cost, the blades are made into blades that can be disassembled and assembled individually, which is convenient for individual disassembly and replacement and can effectively reduce costs. Therefore, both sides of the blade root are made into corrugated guiding structures for installation outside the turbine.

[0003] The currently used machine tools have the following disadvantages: 1. The original machine tool uses the method of manual positioning. The workpiece is placed in the machine tool, and a three-axis grinding machine is used for grinding. It is necessary to first use a planing structure to plane arc grooves on both sides of the blade root, and then switch the grinding parts for fine grinding, or use two processes for processing. The efficiency is insufficient, and there is a lack of a flow-type processing structure that can automatically process. 2. There is a lack of synchronous automatic advancement, and there is no conveying structure that does not affect the automatic feeding of workpieces. 3.

[0031] Embodiment 3: Based on Embodiment 1, place the blade in the positioning frame 405 above the front side, and take out the blade in the positioning frame 405 at the rear side of the equipment. Only manual picking and placing are required. After taking out the blade, use a gauge to measure. When an error beyond the range occurs, stop the machine and replace the fitting; when the fine grinding module 10 is worn out greatly and an error occurs, directly replace the fine grinding module 10 at this time. Loosen the setscrew in the transmission wheel 902 to slide the transmission wheel 902, and pull out the trapezoidal shaft pile 903 from the trapezoidal groove 1001, then the fine grinding module 10 can be slid out to one side for replacement.

[0032] The specific usage method and function of this embodiment: In the present invention, during operation, place the blade in the positioning frame 405 above the front side, and take out the blade in the positioning frame 405 at the rear side of the equipment. Only manual picking and placing are required. After taking out the blade, use a gauge to measure. When an error beyond the range occurs, stop the machine and replace the fitting; A servo motor is set to control the conveyor belt 103. Each time the conveyor belt 103 moves, the blade advances one station. After feeding, start the electric cylinder 2 to drive the connecting rod 201 and the straight guide rod 202 to move. The straight guide rod 202 drives the lock 3 to move to the right. After the lock 3 passes through the support frame 5, it continues to move to the right, triggering the piston 302 to contact the left side of the blade and then push the blade to the right, thereby pulling the trigger carriage 403 to move to the right, inserting the docking pile 404 into the docking hole 603 for positioning. At the same time, the trigger piston 302 is also automatically contracted under pressure, and the hydraulic oil in the trigger piston 302 is input into the self-locking piston 301, expanding the two groups of self-locking pistons 301. The trapezoidal blocks at the telescopic ends of the self-locking pistons 301 contact the wedge-shaped block structure on the right side of the support frame 5 for self-locking fixation. Start the rough grinding motor 802 to drive the rough grinding roller 801 to rotate, providing the rough grinding function. Start the fine grinding motor 901 to drive the transmission wheel 902 and the trapezoidal shaft pile 903 to rotate. The trapezoidal shaft pile 903 slides in the trapezoidal groove 1001 to drive the fine grinding module 10 to move. By using the high-frequency reciprocating movement of the fine grinding module 10, a grinding effect is generated to provide the fine grinding function. Start the longitudinal axis motor 602 to drive the longitudinal axis lead screw 601 to rotate, and then drive the processing seat 7 to move, enabling longitudinal axis feeding. Start the height control motor 702 to drive the height control lead screw 701 to rotate, and then drive the rough grinding frame 8 or the fine grinding frame 9 to move up and down, enabling adjustment of the height axis. Automatic grinding processing can be completed through double-axis adjustment, and the generated waste chips will naturally fall into the recycling drawer 102. After the processing is completed, reset the electric cylinder 2. The trigger carriage 403 will automatically reset through the spring to ensure continuous feeding. By rough grinding first and then fine grinding, the working mode of switching grinding parts can be replaced.
