[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a CNC lathe and a processing method for a car cabin hinge.

[0042] Example 1:

[0043] See also Figure 1 - Figure 10A CNC lathe comprises a lathe base 1, a lathe shell 2 is mounted on the top of the lathe base 1, a sliding cover 3 is slidably mounted on the outside of the lathe shell 2, a processing chamber 4 is opened inside the sliding cover 3, a power mechanism 5 is mounted on the inner wall of the processing chamber 4, a clamping mechanism 6 is mounted inside the power mechanism 5, a movable slide rail 7 is mounted inside the processing chamber 4, a movable base 8 is slidably mounted on the outside of the movable slide rail 7, a connecting assembly 9 is mounted on the outside of the movable base 8, and a processing mechanism 10 is mounted on the outside of the movable base 8;

[0044] The connecting assembly 9 and the processing mechanism 10 are both slidably mounted on the outside of the movable slide rail 7 via the movable base 8. The movable base 8 is slidably mounted on the inside of the processing chamber 4 via the movable slide rail 7. An opening is provided on the outside of the lathe housing 2. The sliding cover 3 can move outside the lathe housing 2 and seal the external opening of the sliding cover 3.

[0045] The power mechanism 5 can drive the clamping mechanism 6 to move inside the power mechanism 5. When the clamping mechanism 6 moves toward the center of the power mechanism 5, it can clamp the workpiece to be processed. When the movable base 8 moves inside the processing chamber 4 along the outside of the movable slide rail 7, it can drive the connecting component 9 and the processing mechanism 10 to move synchronously. When the connecting component 9 moves inside the processing chamber 4, it can be connected to the inside of the power mechanism 5. When the processing mechanism 10 moves inside the processing chamber 4, it can process the outside of the workpiece.

[0046] When working, the workpiece to be processed is first placed on the clamping mechanism 6. After the workpiece is placed on the clamping mechanism 6, the power mechanism 5 drives multiple clamping mechanisms 6 to move toward the center of the power mechanism 5 at the same time. When the clamping mechanism 6 moves toward the center of the power mechanism 5, the clamping mechanism 6 can fix the position of the power mechanism 5. After the clamping mechanism 6 fixes the position of the workpiece, the movable base 8 moves along the outside of the movable slide rail 7 toward the direction of the power mechanism 5. When the movable base 8 moves, it can drive the connecting component 9 and the processing mechanism 10 to move synchronously. During the movement of the connecting component 9 toward the power mechanism 5, it can be connected with the power mechanism 5. After the connecting component 9 is connected with the power mechanism 5, the processing mechanism 10 can process the workpiece fixed on the clamping mechanism 6. During the processing, the processing mechanism 10 and the power mechanism 5 on which the workpiece is installed are connected by the connecting component 9, so that the vibrations generated by the workpiece and the processing mechanism 10 during the processing can be transmitted to each other. When the workpiece and the processing mechanism 10 vibrate at the same frequency, it can effectively prevent the workpiece from having vibration marks during processing and the processing mechanism 10 from being damaged during processing.

[0047] Example 2:

[0048] The difference from the above embodiment is that, please refer to Figure 1 - Figure 10The power mechanism 5 includes a driving turntable 51, which is mounted on the inner wall of the lathe housing 2. A transmission turntable 52 is mounted on the outside of the driving turntable 51, a clamping mounting plate 53 is mounted on the outside of the transmission turntable 52, a transmission connecting block 55 is mounted on the outside of the clamping mounting plate 53, and a transmission connecting groove 56 is mounted on the inside of the transmission connecting block 55;

[0049] A plurality of clamping sliding grooves 54 are provided inside the clamping mounting plate 53 , and a clamping mechanism 6 is movably installed inside each of the plurality of clamping sliding grooves 54 .

[0050] The transmission turntable 52 is mounted inside the processing chamber 4 through the clamping mounting plate 53. A spiral chute is provided inside the transmission turntable 52. The transmission turntable 52 is connected to the plurality of clamping mechanisms 6 through the internal chute.

[0051] The driving turntable 51 can drive the transmission turntable 52 to rotate inside the processing chamber 4. When the transmission turntable 52 rotates forward, it can drive the clamping mechanism 6 to move toward the center of the clamping mounting plate 53. When the transmission turntable 52 rotates reversely, it can drive the clamping mechanism 6 to move toward the edge of the clamping mounting plate 53.

[0052] The clamping mounting plate 53 is connected to the inner wall of the lathe housing 2 through the transmission connecting block 55, and the transmission connecting block 55 is clamped to the outside of the connecting assembly 9 through the transmission connecting groove 56;

[0053] When the movable base 8 drives the connecting component 9 to move inside the lathe base 1, the outside of the connecting component 9 can be engaged with the transmission connecting groove 56 inside the power mechanism 5, and the power mechanism 5 and the movable base 8 can be connected by engaging the connecting component 9 with the transmission connecting groove 56 inside the transmission connecting block 55.

[0054] During operation, the clamping mounting plate 53 is installed on the side wall of the lathe housing 2 through the transmission connecting block 55. When the workpiece needs to be fixed, the transmission turntable 52 is driven to rotate forward by driving the turntable 51. When the transmission turntable 52 rotates forward, it can drive all the clamping mechanisms 6 to move along the clamping sliding groove 54 toward the center of the clamping mounting plate 53. When the clamping mechanism 6 moves toward the center of the clamping mounting plate 53, the clamping mechanism 6 can clamp the workpiece so that the processing mechanism 10 can process the workpiece. During the movement of the movable base 8, the connecting component 9 can be inserted into the interior of the transmission connecting groove 56. In the process of the movable base 8 driving the connecting component 9 to move, the connecting component 9 can be more tightly connected to the transmission connecting groove 56. After the connection is completed, the workpiece on the clamping mechanism 6 can be processed. After the processing is completed, the mobile base 8 moves away from the power mechanism 5. When the mobile base 8 moves, it can drive the connecting component 9 to separate from the inside of the transmission connecting groove 56. After the connecting component 9 is separated from the inside of the transmission connecting groove 56, the turntable 51 is driven to drive the transmission turntable 52 to rotate in the opposite direction. When the transmission turntable 52 rotates in the opposite direction, it can drive the clamping mechanism 6 to move synchronously toward the edge of the clamping mounting plate 53. When the clamping mechanism 6 moves toward the edge of the clamping mounting plate 53, the clamping mechanism 6 can relax the clamping of the workpiece, and then remove the processed workpiece from the clamping mechanism 6. During the processing, the power mechanism 5 drives multiple clamping mechanisms 6 to move synchronously to clamp the workpiece, which can fix the workpiece in the center position, thereby improving the accuracy of the subsequent processing mechanism 10 on the workpiece.

[0055] Example 3:

[0056] The difference from the above embodiment is that, please refer to Figure 1 - Figure 10 The clamping mechanism 6 includes a workpiece limiting block 61 and a block limiting clamping block 63. The workpiece limiting block 61 is slidably installed inside the clamping sliding groove 54, and the block limiting clamping block 63 is installed outside the clamping mounting plate 53. A block limiting sliding groove 62 is provided on the outside of the workpiece limiting block 61. A workpiece fixing clamping block 64 is slidably installed inside the workpiece limiting block 61, and a clamping block transmission connecting rod 65 is installed on the outside of the workpiece fixing clamping block 64. A transmission mounting column 66 is installed on the outside of the clamping block transmission connecting rod 65.

[0057] The outside of the workpiece fixing clamp 64 is connected to the transmission mounting post 66 via a clamp transmission connecting rod 65. The outside of the transmission mounting post 66 is slidably mounted in a slide groove inside the transmission turntable 52. The lengths of the clamp transmission connecting rods 65 on the multiple clamping mechanisms 6 are different.

[0058] When the transmission turntable 52 rotates, it can drive the clamp transmission connecting rod 65 to move through the transmission mounting column 66 and the clamp transmission connecting rod 65. When the workpiece fixing clamp 64 moves, it can drive the workpiece limit block 61 to move synchronously. When the transmission turntable 52 rotates forward, it can drive the workpiece limit block 61 to move toward the center of the clamping mounting plate 53. When the transmission turntable 52 rotates reversely, it can drive the workpiece limit block 61 to move toward the edge of the clamping mounting plate 53.

[0059] The block limit slot 62 provided on the side of the workpiece limit block 61 is an inclined structure, and the workpiece limit block 61 is slidably connected to the outside of the block limit clamping block 63 through the block limit slot 62;

[0060] When the transmission turntable 52 rotates to drive the workpiece limiting block 61 to move inside the clamping sliding groove 54 , the workpiece limiting block 61 can move up and down inside the clamping sliding groove 54 through the sliding connection between the block limiting sliding groove 62 and the block limiting clamping block 63 .

[0061] When the transmission turntable 52 rotates forward, it can drive the transmission mounting post 66 connected to the transmission mounting post 66 on the clamping block transmission connecting rod 65 to move toward the center of the transmission turntable 52. When the transmission mounting post 66 moves toward the center of the transmission connecting block 55, it can drive the workpiece fixing clamping block 64 to move toward the center of the clamping mounting plate 53. When the workpiece fixing clamping block 64 moves toward the center of the clamping mounting plate 53, it can fix the workpiece to be processed. When the workpiece fixing clamping block 64 moves toward the center of the clamping mounting plate 53, it can drive the external workpiece limiting block 61 to move synchronously. When the workpiece limiting block 61 moves along the clamping sliding groove 54 toward the center of the clamping mounting plate 53, the block limiting card block 63 can be slidably connected with the slide groove on the block limiting slide 62 outside the workpiece limiting block 61, driving the workpiece limiting block 61 to move toward the direction of the workpiece. When the workpiece fixing clamp 64 moves toward the center of the clamping mounting plate 53 to fix the fixture, the workpiece limiting block 61 can be driven to block the workpiece. After the workpiece limiting block 61 blocks the workpiece, it can prevent the processing mechanism 10 from damaging the clamping mounting plate 53 when processing the workpiece on the clamping mechanism 6. After the processing is completed, the transmission turntable 52 rotates in the opposite direction to drive the transmission mounting post 66 to move toward the edge of the clamping mounting plate 53. When the transmission mounting post 66 moves toward the edge of the clamping mounting plate 53, it can drive the workpiece fixing clamp 64 and the workpiece limiting block 61 to move toward the edge of the clamping mounting plate 53. When the workpiece fixing clamp 64 moves toward the edge of the clamping mounting plate 53, the clamping of the workpiece can be released, and then the processed workpiece can be removed from the workpiece fixing clamp 64.

[0062] Example 4:

[0063] The difference from the above embodiment is that, please refer to Figure 1 - Figure 10 The connecting assembly 9 includes a transmission connecting rod 91, one end of which is connected to the outside of the mobile base 8, and the other end of the transmission connecting rod 91 is connected to a card block baffle 92. A connecting card block slot 93 is provided inside the transmission connecting rod 91, and a transmission connecting card block 94 is slidably installed on the outside of the transmission connecting rod 91. A card block mounting block 95 is installed inside the transmission connecting card block 94;

[0064] The transmission connection block 94 is slidably installed in the connection block slot 93 provided inside the transmission connection rod 91 through the block installation block 95 .

[0065] The outer portion of the transmission connecting rod 91 is engaged with the transmission connecting groove 56 inside the transmission connecting block 55 via the transmission connecting clamping block 94. The end of the transmission connecting rod 91 connected to the movable base 8 is wider than the end connected to the clamping block baffle 92.

[0066] When the movable base 8 drives the transmission connecting rod 91 to move, the transmission connecting clamping block 94 can be clamped into the interior of the transmission connecting groove 56. When the transmission connecting rod 91 moves, it can drive the transmission connecting clamping block 94 to move to both sides to clamp the transmission connecting block 55.

[0067] During operation, the movable base 8 can drive the connecting assembly 9 and the processing mechanism 10 to move along the outside of the movable slide rail 7. When the movable base 8 drives the connecting assembly 9 and the processing mechanism 10 to move in the direction of the clamping mechanism 6, the transmission connection card block 94 on the outside of the transmission connecting rod 91 can be inserted into the inside of the transmission connection groove 56. After the transmission connection card block 94 is inserted into the inside of the transmission connection groove 56, the transmission connecting rod 91 continues to move. At this time, the transmission connection card block 94 cannot continue to move under the restriction of the transmission connection groove 56. During the continued movement of the transmission connecting rod 91, the transmission connection card block 94 can be squeezed to move to both sides. When the transmission connection card block 94 moves to both sides, it can be more tightly connected to the transmission connection block 55 on the clamping mounting plate 53. After the transmission connecting block 55 on the mounting plate 53 is connected, when the processing mechanism 10 processes the workpiece on the clamping mechanism 6, the vibration between the workpiece and the processing mechanism 10 can be transmitted through the transmission connecting rod 91. When the vibration can be transmitted to each other, the surface of the workpiece of the processing mechanism 10 can be prevented from having vibration marks during the processing, and the processing mechanism 10 can also be prevented from being damaged during the processing. After the processing is completed, the base 8 is moved to drive the connecting component 9 and the processing mechanism 10 to move away from the clamping mechanism 6. During the movement of the connecting component 9, the transmission connecting rod 91 can move first. After the transmission connecting rod 91 moves a certain distance, it can continue to drive the transmission connection block 94 to move through the block baffle 92. After the transmission connection block 94 moves, the separation between the connecting component 9 and the clamping mechanism 6 can be completed.
