[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] According to Figures 1-6 A numerically controlled machining machine tool for an automotive half shaft shown in the figure includes a machine base 1. One side of the top end of the machine base 1 is fixedly installed with a machine case 2. A turntable 21 is installed on the outer surface of one side of the machine case 2. A motor is fixedly installed inside the machine case 2, and the turntable 21 is driven to rotate by the motor. The center of the outer surface of one side of the machine case 2 is fixedly installed with a first mounting table 22. A second mounting table 23 is arranged above the first mounting table 22 on the outer surface of one side of the machine case 2. An adjusting assembly is arranged inside the turntable 21, and the position of the second mounting table 23 is adjusted through the adjusting assembly. A drill bit 24 is installed at the front end of the first mounting table 22. An installation assembly is arranged inside the first mounting table 22, and the drill bit 24 is installed and fixed through the installation assembly;

[0032] Further, the adjusting assembly includes a first sliding groove 25 formed on the outer surface of the turntable 21, and a first screw rod 251 is rotatably installed inside the first sliding groove 25. A slider 231 is fixedly installed on the rear outer surface of the second mounting table 23, and the slider 231 is sleeved on the outer surface of the first screw rod 251. The first screw rod 251 is threadedly connected to the slider 231. A slide rod 26 is inserted into the top end of the first screw rod 251. A clamping plate 261 is fixedly installed at the top end of the slide rod 26. A groove is formed on the top outer surface of the clamping plate 261. A clamping ring 28 is fixedly installed at the top end inside the turntable 21, and the clamping ring 28 is sleeved on the outer surface of the clamping plate 261. The clamping ring 28 and the clamping plate 261 are engaged with each other. Push the clamping plate 261 downward to disengage the clamping plate 261 from the clamping ring 28, releasing the limit on the clamping plate 261. Then rotate the clamping plate 261 to drive the first screw rod 251 below to rotate. The slider 231 is threadedly connected to the first screw rod 251, driving the second mounting table 23 to slide along the first sliding groove 25.

[0033] Further, a retaining ring 29 is fixedly installed above the slider 231 inside the turntable 21. A second return spring 27 is sleeved on the outer surface of the slide rod 26 above the retaining ring 29. The mounting assembly includes a mounting rod 241 fixedly installed at one end of the drill bit 24. A clamping post 221 is provided on the inner wall of the first mounting table 22, and a card slot 242 matching with one end of the clamping post 221 is formed around the outer surface of the mounting rod 241. Start the electromagnet 224 inside the first mounting table 22. Drive the clamping post 221 to move outward by the magnetic force of the electromagnet 224, so that one end of the clamping post 221 disengages from the card slot 242 on the surface of the mounting rod 241, releasing the limit on the drill bit 24, facilitating the removal and replacement of the drill bit 24.

[0034] Further, a guide rod 222 is fixedly installed on the inner wall of the turntable 21, and the clamping post 221 is sleeved on the outer surface of the guide rod 222. A first return spring 223 is sleeved on the outer surface of the guide rod 222 at one end of the clamping post 221. An electromagnet 224 is sleeved on the outer surface of the guide rod 222 at one end of the first return spring 223. When the clamping post 221 slides along the guide rod 222, it will squeeze the second return spring 27. After the replacement is completed, turn off the electromagnet 224, and the second return spring 27 will push the clamping post 221 inward.

[0035] The implementation method is specifically as follows: The first installation table 22 is installed at the center position of the turntable. A drill bit 24 can be installed to perform hole opening treatment on the automotive half shaft. The second installation table 23 is located on the side of the turntable. A corresponding tool can be installed to perform circular motion to process the automotive half shaft. According to the specified radius of the automotive half shaft, the position of the second installation table 23 is adjusted through the adjustment component, so as to process automotive half shafts of different specifications. When adjusting the second installation table 23, a tool is inserted into the groove on the surface of the clamping plate 261, and the clamping plate 261 is pushed downward, so that the clamping plate 261 is disengaged from the clamping ring 28, releasing the limit on the clamping plate 261. Then, the clamping plate 261 is rotated to drive the first screw rod 251 below to rotate. The slider 231 is threadedly connected to the first screw rod 251, driving the second installation table 23 to slide along the first chute 25. During the process of pushing the clamping plate 261 downward, the first return spring 223 will be compressed, and the sliding rod 26 slides along the first screw rod 251. After the position of the second installation table 23 is adjusted, the clamping plate 261 is released, and the first return spring 223 will push the clamping plate 261 upward, so that the clamping plate 261 is embedded in the clamping ring 28 for limiting. When the drill bit 24 needs to be replaced, the electromagnet 224 in the first installation table 22 can be started. The magnetic force of the electromagnet 224 drives the clamping column 221 to move outward, so that one end of the clamping column 221 is disengaged from the clamping groove 242 on the surface of the installation rod 241, releasing the limit on the drill bit 24, facilitating the removal and replacement of the drill bit 24. The clamping column 221 slides along the guide rod 222 and will compress the second return spring 27. After the replacement is completed, the electromagnet 224 is turned off, and the second return spring 27 will push the clamping column 221 inward, so that one end of the clamping column 221 is inserted into the clamping groove 242.
