[0023] like Figure 3-4 As shown, this example allows for easy and quick replacement of different sized cutting tools 108.

[0024] The machine tool includes a tool changer 102, a hydraulic cylinder I 103, a cross 104, four driven shafts 105, and four cutting tools 108. One end of the hydraulic cylinder I 103 is fixedly connected to the bottom of the tool changer 102, and the cross 104 is rotatably connected to the other end of the hydraulic cylinder I 103. The four driven shafts 105 are slidably connected to the four ends of the cross 104, and the four cutting tools 108 are fixedly connected to the bottom of their respective driven shafts 105. The four cutting tools 108 are of different sizes, which drives the hydraulic cylinder I 103, causing the cross 104 to move downward. The cross 104 then causes the driven shafts 105 to move out of the machining position, and the cross 104 can be rotated so that the different driven shafts 105 are in the machining position. Different sizes of cutting tools 108 are fixedly connected to the different driven shafts 105, thus enabling the cutting tools 108 of different sizes to be in the machining position quickly and easily.

[0025] like Figure 3-4 As shown, this example can achieve a more secure contact between the driven shaft 105 and the main shaft 109.

[0026] The machine tool also includes four rotating rings 106, four tension springs I 107, and a spindle 109. The spindle 109 is rotatably connected to the bottom of the tool changer 102. A cross protrusion is provided on the spindle 109, and a cross groove is provided on each driven shaft 105. The four rotating rings 106 are rotatably connected to their respective driven shafts 105. The four tension springs I 107 are fixedly connected between their respective rotating rings 106 and the cross 104. The output shaft of the first rotary motor is fixedly connected to the spindle 109. The tension springs I 107 pull the rotating rings 106 upwards, thus causing the rotating rings 106 to... The driven shaft 105 and the tool 108 are pulled upwards, causing the tool 108, which is not in the machining position, to retract into the cross 104, preventing the tool 108 from colliding. Then, the cross protrusion of the spindle 109 is inserted into the cross groove of the driven shaft 105, which is in the machining position. Then, the tension spring I 107 pulls the driven shaft 105 upwards, making its contact with the spindle 109 more secure. Then, the first rotary motor drives the spindle 109 and the driven shaft 105 to rotate, causing the tool 108 to rotate for machining, thereby achieving the effect of making the contact between the driven shaft 105 and the spindle 109 more secure.

[0027] like Figure 3-6 As shown, this example allows for easy up-and-down movement of the tool 108 to machine the workpiece.

[0028] Since the machine tool also includes a slider 101, a push rod 201, a baffle 203, a threaded shaft 205, a compression spring I 207, and a bottom rod 208, the slider 101 is fixedly connected above the tool changer 102, the push rod 201 is slidably connected to the outside of the slider 101, the threaded shaft 205 is rotatably connected to the bottom of the push rod 201, the bottom rod 208 is threadedly connected to the bottom of the threaded shaft 205, the baffle 203 is slidably connected to the outside of the push rod 201 and the bottom rod 208, and the compression spring I 207 is fixedly connected between the baffle 203 and the bottom rod 208. The push rod 201 is equipped with... A second rotary motor is provided, and a threaded shaft 205 is fixedly connected to the output shaft of the second rotary motor. The second rotary motor is then started, causing the threaded shaft 205 to rotate, which in turn causes the threaded shaft 205 to move downward along the bottom rod 208. The threaded shaft 205 then causes the push rod 201 to move downward along the baffle 203. The push rod 201 then causes the tool changer 102 and the tool 108 to move downward together, thereby enabling the tool 108 to perform vertical machining on the workpiece. This achieves the effect of facilitating the up-and-down movement of the tool 108 to machine the workpiece.

[0029] like Figure 3-10 As shown, this example enables the tool 108 to perform arc machining on the workpiece.

[0030] Since the machine tool also includes an elastic plate 206 and a base 401, the elastic plate 206 is fixedly connected to the bottom of the baffle 203. The elastic plate 206 is provided with an inclined surface. The base 401 is fixedly connected to the bottom rod 208. The baffle 203 is pressed down, causing the elastic plate 206 to move downward. The bottom rod 208 then pushes the inclined surface of the elastic plate 206 outward, causing the elastic plate 206 to lock the baffle 203 and the bottom rod 208. The baffle 203 is then separated from the push rod 201. At this time, the second rotary motor is started, which causes the push rod 201 to rotate. The push rod 201 then drives the tool changer 102 and the tool 108 to rotate together, so that the tool 108 can perform arc machining on the workpiece, thereby achieving the effect of making it easier for the tool 108 to perform arc machining on the workpiece.

[0031] like Figure 3-10 As shown, this example can achieve the effect of preventing the threaded shaft 205 from rotating relative to the base rod 208.

[0032] Since the machine tool also includes a insertion rod 204, which is slidably connected to the baffle 203, and a tension spring II is fixedly connected between the insertion rod 204 and the baffle 203, and an insertion hole is provided on the threaded shaft 205, the insertion rod 204 is blocked by the push rod 201 in the initial position and cannot move inward. Then the baffle 203 moves downward, which can drive the insertion rod 204 to move downward together. Then the tension spring II pulls the insertion rod 204 inward, and the insertion rod 204 is inserted into the insertion hole on the threaded shaft 205, thereby locking the threaded shaft 205 and the bottom rod 208, preventing the threaded shaft 205 and the bottom rod 208 from rotating relative to each other, thus achieving the effect of preventing the threaded shaft 205 from rotating relative to the bottom rod 208.

[0033] like Figure 3-8 As shown, this example demonstrates how the tool 108 can be moved along its plane to machine a workpiece.

[0034] Since the machine tool also includes a threaded rod II 402 and a hydraulic cylinder II 202, the threaded rod II 402 is rotatably connected to the base 401, the bottom rod 208 is threadedly connected to the threaded rod II 402, one end of the hydraulic cylinder II 202 is fixedly connected to the top rod 201, and the other end of the hydraulic cylinder II 202 is fixedly connected to the slider 101. A third rotary motor is provided on the threaded rod II 402. When the hydraulic cylinder II 202 is started, it can drive the slider 101 to move back and forth along the top rod 201. The slider 101 then drives the cutting tool to move back and forth for machining. When the third rotary motor is started, it can drive the bottom rod 208 to move left and right. The bottom rod 208 then drives the top rod 201 and the slider 101 to move left and right. The slider 101 then drives the cutting tool to move left and right for machining. This achieves the effect of machining the workpiece by moving the cutting tool 108 in a plane.

[0035] like Figure 7-10 As shown, this example can facilitate the clamping of machined parts of different shapes using fixture 306.

[0036] The machine tool also includes a slide frame 301, a rotating handle 302, and two threaded rods I 303. The slide frame 301 is fixedly connected to the top of the base 401. The rotating handle 302 is rotatably connected to the slide frame 301. The two threaded rods I 303 are rotatably connected inside the slide frame 301. The rotating handle 302 is connected to the two threaded rods I 303 respectively. Each threaded rod I 303 is threaded with two clamping blocks 304. All four clamping blocks 304 are slidably connected to the upper slide frame 301. Each clamping block 304 is rotatably connected with a recess. The groove block 305 has a clamp 306 fixedly connected to each groove block 305. The threads at both ends of the threaded rod I 303 are turned in opposite directions. Rotating the handle 302 can drive the two threaded rods I 303 to rotate, causing the clamp blocks 304 at both ends of the threaded rods I 303 to slide towards the middle. In turn, the clamp blocks 304 drive the groove blocks 305 and the clamps 306 to slide towards the middle. As a result, the four clamps 306 rotate and fit against the surface of the workpiece, thus achieving the effect of facilitating the clamping of workpieces of different shapes with the clamps 306.

[0037] like Figure 7-8 As shown, this example allows for easy fixation of the angle of fixture 306 during machining.

[0038] Since the machine tool also includes a slide 307, one end of a hydraulic cylinder III is fixedly connected to the lower part of the slide 307, and the other end of the hydraulic cylinder III is fixedly connected to the upper part of the slide frame 301. Each clamping block 304 has a sliding plate 308 slidably connected to both sides. The eight sliding plates 308 are slidably connected to the slide 307. When the clamping fixture 306 clamps the workpiece, the hydraulic cylinder III is activated, which drives the slide 307 to move upward. The slide 307 then drives the eight sliding plates 308 to move upward, inserting the sliding plates 308 into the groove block 305. This fixes the angle of the groove block 305, preventing it from rotating, and thus fixes the angle of the clamping fixture 306. This achieves the effect of easily fixing the angle of the clamping fixture 306 during processing.

[0039] like Figure 9-10 As shown, this example demonstrates how to easily move the machine tool.

[0040] Since the machine tool also includes a wheel frame 403 and a threaded rod III 406, the threaded rod III 406 is rotatably connected to the bottom of the base 401, the wheel frame 403 is slidably connected to the bottom of the base 401, the wheel frame 403 is threadedly connected to the threaded rod III 406, and four rotating wheels 404 are rotatably connected to the wheel frame 403. The output shaft of a fourth rotary motor is fixedly connected to the threaded rod III 406, thereby starting the fourth rotary motor, which can drive the threaded rod III 406 to rotate, thereby causing the threaded rod III 406 to drive the wheel frame 403 to move downward, and then the four rotating wheels 404 to contact the ground, so that the machine tool can be pushed to change position, thereby achieving the effect of facilitating the movement of the machine tool.

[0041] like Figure 9-10 As shown, this example can help improve the stability of machine tools during processing.

[0042] Since the machine tool also includes bevel gear I 407 and two threaded rods IV 408, the two threaded rods IV 408 are rotatably connected to the base 401. Each threaded rod IV 408 is threadedly connected to a support plate 405. Bevel gear I 407 is fixedly connected to threaded rod III 406, and each threaded rod IV 408 is fixedly connected to a bevel gear II 409. Bevel gear I 407 and the two bevel gears II 409 are meshed and connected for transmission. Therefore, when the wheel frame 403 is retracted, threaded rod III 406 rotates, which drives bevel gear I 407 to rotate. In turn, bevel gear I 407 drives the two bevel gears II 409 and the two threaded rods IV 408 to rotate. As a result, threaded rods IV 408 support the support plate 405 outward, causing the support plate 405 to extend out of the machine tool, thereby improving the stability of the machine tool and achieving the effect of facilitating the improvement of the stability of the machine tool during processing.
