[0028] When working, the driving motor 71 can drive the motor roller 72 to rotate. When the motor roller 72 rotates, the upper rotating rod 74 can be driven to rotate inside the upper mounting seat 75 through the transmission belt 73 and the upper roller 76.

[0029] Example 3: The difference from the above example is that, please refer to Figure 1 - Figure 12The workpiece rotating mechanism 8 includes a clamp housing 81 and a rotation limit ring 82. The clamp housing 81 is rotatably mounted on the outside of the workpiece fixing seat 6, and the rotation limit ring 82 is fixedly mounted on the inside of the workpiece fixing seat 6. The workpiece clamping mechanism 9 is installed inside the clamp housing 81, and the workpiece clamping mechanism 9 is installed outside the clamping block limit plate 83. The outside of the clamping block limit plate 83 is connected to the sleeve connecting rod 84, and the outside of the clamping block limit plate 83 is connected to the sleeve spring 85. The outside of the sleeve connecting rod 84 is installed with a transmission block 86, and the outside of the sleeve connecting rod 84 is installed with a transmission connecting sleeve 87. The outside of the transmission connecting sleeve 87 is installed with a limiting block 88, and the outside of the transmission connecting sleeve 87 is provided with a transmission connecting groove 89.

When the transmission rotating rod 79 moves, it can drive the transmission connecting sleeve 87 to move synchronously.

[0032] During operation, the transmission connection block 710 can drive the transmission connection sleeve 87 to rotate by contacting the transmission connection groove 89. When the transmission connection sleeve 87 rotates, the clamping block limit plate 83 can be driven to rotate through the sleeve connection rod 84. When the clamping block limit plate 83 rotates, the workpiece clamping mechanism 9 can be driven to move toward the center of the fixture housing 81. When the workpiece clamping mechanism 9 moves toward the center of the fixture housing 81, it can clamp the workpiece. After the workpiece is clamped, the transmission rotating rod 79 moves toward the workpiece rotating mechanism 8 to drive the transmission connection sleeve 87 to move toward the clamping block limit plate 83. When the clamp housing 81 rotates, the workpiece clamping mechanism 9 and the clamped workpiece can be driven to rotate synchronously, and the transmission connection sleeve 87 can also be connected with the internal part of the rotation limit ring 82 through the limit block 88 to prevent the clamp block limit plate 83 from rotating during the rotation of the clamp housing 81, causing the workpiece clamping mechanism 9 to loosen the clamping of the workpiece and affect the clamping effect.

[0033] Example 4: The difference from the above example is that please refer to Figure 1 - Figure 12 The workpiece clamping mechanism 9 includes a clamping block moving seat 91, which is slidably mounted inside the fixture housing 81, a clamping block transmission column 92 is mounted on the outside of the clamping block moving seat 91, a workpiece clamping block 93 is slidably mounted on the outside of the clamping block moving seat 91, a lifting block 94 is mounted inside the workpiece clamping block 93, a lifting screw 95 is mounted on the outside of the lifting block 94, and an adjusting knob 96 is mounted inside the clamping block moving seat 91; The outside of the clamp block moving seat 91 is clamped with the inside of the clamp block limiting plate 83 through the clamp block transmission column 92.

When the clamp block moving seat 91 moves toward the center of the fixture housing 81, it can drive the workpiece clamp block 93 to move toward the center of the fixture housing 81.

[0034] The outside of the lifting screw 95 is threadedly connected to the inside of the adjustment knob 96. The bottom of the lifting screw 95 is clamped to the inside of the workpiece clamp 93 through the lifting block 94. The top of the lifting screw 95 is connected to the workpiece clamp 93. When the adjusting knob 96 is rotated, the lifting screw 95 can be driven to move up and down. When the lifting screw 95 moves up and down, the workpiece clamping block 93 can be driven to move up and down outside the clamping block moving seat 91.

[0035] During operation, the clamp block limit plate 83 is first rotated to drive the clamp block moving seat 91 toward the center of the fixture housing 81 to move the workpiece clamp block 93 to clamp the workpiece. After the workpiece clamp block 93 clamps the workpiece, observe whether the other workpiece clamp blocks 93 are tightly fitted to the workpiece. During the clamping process, the lifting screw 95 can be driven up and down by rotating the adjusting knob 96. When the lifting screw 95 moves up and down, it can drive the workpiece clamp block 93 to move up and down outside the clamp block moving seat 91. By adjusting the up and down positions of the workpiece clamp block 93, the workpiece clamp block 93 can be made to fit more closely with the workpiece, thereby increasing the fixing effect on the workpiece.

When the workpiece clamping mechanism moves toward the center of the fixture shell, it can clamp the workpiece.

7. A CNC lathe according to claim 6, characterized in that: The sleeve connecting rod and the transmission connecting sleeve are slidably connected, the sleeve connecting rod is clamped with the inner part of the transmission connecting sleeve through the external transmission clamping block, the outer part of the transmission connecting sleeve is connected to the clamping block limit plate through the sleeve spring, and the outer part of the transmission connecting sleeve is clamped with the inner part of the rotation limit ring through the limit clamping block; When the transmission connection sleeve rotates, it can drive the sleeve connecting rod to rotate synchronously through the transmission block. When the transmission connection sleeve slides along the outside of the sleeve connecting rod, it can drive the sleeve spring to expand and contract. When the transmission rotating rod moves, it can drive the transmission connection sleeve to move synchronously.

8. A CNC lathe according to claim 7, characterized in that: The workpiece clamping mechanism includes a clamping block moving seat, which is slidably mounted inside the fixture housing, a clamping block transmission column is mounted on the outside of the clamping block moving seat, a workpiece clamping block is slidably mounted on the outside of the clamping block moving seat, a lifting block is mounted inside the workpiece clamping block, a lifting screw is mounted on the outside of the lifting block, and an adjusting knob is mounted inside the clamping block moving seat; The outside of the clamp block movable seat is clamped with the inside of the clamp block limit plate through the clamp block transmission column. When the clamp block limit plate rotates, it can drive the clamp block movable seat to move toward the center of the fixture shell through the clamp block transmission column. When the clamp block movable seat moves toward the center of the fixture shell, it can drive the workpiece clamp block to move toward the center of the fixture shell.

9. A CNC lathe according to claim 8, characterized in that: The outer portion of the lifting screw is connected to the inner portion of the adjusting knob through a thread, the bottom portion of the lifting screw is clamped to the inner portion of the workpiece clamping block through a lifting clamping block, and the top portion of the lifting screw is connected to the workpiece clamping block; When the adjusting knob is rotated, the lifting screw can be driven to move up and down, and when the lifting screw moves up and down, the workpiece clamping block can be driven to move up and down outside the clamping block moving seat.

10. A positioning method for brake assembly processing, characterized in that: Using a CNC lathe according to any one of claims 1 to 9, comprising the following steps: During operation, the workpiece to be processed is placed at the center of the workpiece rotating mechanism; Then, the workpiece clamping mechanism is driven by the clamping drive mechanism to move toward the center of the workpiece rotating mechanism to clamp the workpiece to be processed; After the workpiece is fixed, the clamping drive mechanism can drive the workpiece rotating mechanism to rotate, and when the workpiece rotating mechanism rotates, the workpiece can be driven to rotate synchronously through the workpiece clamping mechanism; The workpiece cutting mechanism can move on the top of the movable slide rail and perform cutting processing on the clamped workpiece.
