Detailed Description

As shown in fig. 1 to 5, a first limiting mechanism 2 is mounted on the left side of the machine head 1, two sets of force applying and feeding mechanisms 4 are respectively arranged in the left and right feeding housings 3, the two sets of force applying and feeding mechanisms 4 respectively penetrate through connecting blocks 5 arranged in the middle parts of the left and right feeding housings 3, and a second limiting mechanism 6 is mounted in the middle of the front ends of the left and right feeding housings 3 and penetrates through a slide rail 7 in the left and right feeding housings.

Further, the stress application feeding mechanism 4 comprises an adjusting knob 8, a nut 9, a transmission shaft 10, a limiting baffle plate 11, a stress application baffle plate 12, a spring 13 and a gasket 14, wherein the adjusting knob 8 is installed at one end of the transmission shaft 10 and is located outside the left feeding shell 3 and the right feeding shell 3, the nut 9 is connected with the transmission shaft 10 and is fixed inside the left feeding shell 3 and the right feeding shell 3, the limiting baffle plate 11 is installed on the transmission shaft 10 and is located at one end of the connecting block 5, the gasket 14 is installed on the transmission shaft 10 and is located at the other end of the connecting block 5, the spring 13 is installed on the transmission shaft 10, one end of the spring 13 is connected with the gasket 14.

Furthermore, the middle section of the transmission shaft 10 of the force-applying feeding mechanism 4 is provided with a smooth surface, the left section and the right section of the smooth surface are provided with threads, and the screwing directions of the threads are opposite.

Further, first spacing mechanism 2 includes adjust knob 8, screw shaft 15, and wherein, adjust knob 8 connection screw shaft 15 one end and lie in the aircraft nose 1 outside, and the other end of screw shaft 15 sets up round hole 16, and round hole 16 is clearance fit with the lift axle 17 in the aircraft nose 1.

The stress application feeding mechanism 4 is arranged on a linear sliding table 18 of the vertical milling key machine through a connecting block 5 and a connecting plate 19, two key clamps 20 are arranged on the upper plane of the stress application feeding mechanism 4, when the stress application feeding mechanism works, keys and key materials needing profiling are respectively arranged in the key clamps 20, a milling cutter is in contact with the profiled keys and the key materials through a control rod 21, the first limiting mechanism 2 is screwed down to enable the clearance fit between the circular hole 16 and the lifting shaft 17 in the machine head 1 to be changed into interference fit to enable the lifting shaft 17 to be limited in the vertical position, and the right hand of an operator is liberated.
