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.

[0022] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a processing method for a numerical control lathe and an automotive cockpit hinge.

[0023] Embodiment 1:

[0024] Please refer to Figure 1 - Figure 10 , a numerical control lathe, including a lathe base 1, a lathe housing 2 is installed on the top of the lathe base 1, a sliding cover plate 3 is slidably installed outside the lathe housing 2, a processing chamber 4 is opened inside the sliding cover plate 3, a power mechanism 5 is installed on the inner wall of the processing chamber 4, a clamping mechanism 6 is installed inside the power mechanism 5, a moving slide rail 7 is installed inside the processing chamber 4, a moving base 8 is slidably installed outside the moving slide rail 7, a connection assembly 9 is installed outside the moving base 8, and a processing mechanism 10 is installed outside the moving base 8; Both the connecting component 9 and the processing mechanism 10 are slidably mounted outside the moving slide rail 7 through the moving base 8. The moving base 8 is slidably mounted inside the processing chamber 4 through the moving slide rail 7. An opening is provided outside the lathe housing 2, and the sliding cover plate 3 can move outside the lathe housing 2 and seal the opening outside the sliding cover plate 3. The power mechanism 5 can drive the clamping mechanism 6 to move inside the power mechanism 5. When the clamping mechanism 6 moves towards the center of the power mechanism 5, it can clamp the workpiece to be processed. When the moving base 8 moves inside the processing chamber 4 along the outside of the moving 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.

[0025] During operation, first place the workpiece to be processed on the clamping mechanism 6. After the workpiece is placed on the clamping mechanism 6, the power mechanism 5 drives a plurality of clamping mechanisms 6 to move towards the center of the power mechanism 5 simultaneously. When the clamping mechanism 6 moves towards 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 moving base 8 moves along the outside of the moving slide rail 7 towards the direction of the power mechanism 5. When the moving 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 towards the power mechanism 5, it can be connected to the power mechanism 5. After the connecting component 9 is connected to 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 mounting the workpiece are connected through 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 appearance of vibration marks on the workpiece during processing and the damage of the processing mechanism 10 during processing.

[0026] Embodiment Two:

[0027] The difference from the above embodiment is that, please refer to Figure 1 - Figure 10 , the power mechanism 5 includes a driving turntable 51, the driving turntable 51 is installed on the inner wall of the lathe housing 2, a transmission turntable 52 is installed outside the driving turntable 51, a clamping mounting plate 53 is installed outside the transmission turntable 52, a transmission connection block 55 is installed outside the clamping mounting plate 53, and a transmission connection groove 56 is installed inside the transmission connection block 55; A plurality of clamping sliding grooves 54 are formed inside the clamping mounting plate 53, and a clamping mechanism 6 is movably installed inside each of the plurality of clamping sliding grooves 54.

[0028] The driving turntable 52 is installed inside the processing bin 4 through the clamping mounting plate 53. A spiral chute is provided inside the driving turntable 52, and the driving turntable 52 is connected to a plurality of clamping mechanisms 6 through the internal chute. The driving turntable 51 can drive the driving turntable 52 to rotate inside the processing bin 4. When the driving turntable 52 rotates forward, it can drive the clamping mechanism 6 to move towards the center of the clamping mounting plate 53. When the driving turntable 52 rotates in the reverse direction, it can drive the clamping mechanism 6 to move towards the edge of the clamping mounting plate 53.

[0029] 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 externally clamped to the connecting component 9 through the transmission connecting groove 56. When the moving base 8 drives the connecting component 9 to move inside the lathe base 1, the outside of the connecting component 9 can be clamped to the transmission connecting groove 56 inside the power mechanism 5. The power mechanism 5 and the moving base 8 can be connected through the clamping of the connecting component 9 to the transmission connecting groove 56 inside the transmission connecting block 55.

[0030] 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 it is necessary to fix the workpiece, the driving turntable 51 drives the driving turntable 52 to rotate forward. When the driving turntable 52 rotates forward, it can drive all the clamping mechanisms 6 to move towards the center of the clamping mounting plate 53 along the clamping sliding groove 54. When the clamping mechanism 6 moves towards 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 moving base 8, the connecting component 9 can be inserted into the internal transmission connecting groove 56, and during the movement of the moving base 8 driving the connecting component 9, the connection between the connecting component 9 and the transmission connecting groove 56 can be made closer. After the connection is completed, the workpiece on the clamping mechanism 6 is processed. After the processing is completed, the moving base 8 moves in a direction away from the power mechanism 5. When the moving 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 separates from the inside of the transmission connecting groove 56, the driving turntable 51 drives the driving turntable 52 to rotate in the reverse direction. When the driving turntable 52 rotates in the reverse direction, it can drive the clamping mechanism 6 to move towards the edge of the clamping mounting plate 53 synchronously. When the clamping mechanism 6 moves towards the edge of the clamping mounting plate 53, the clamping mechanism 6 can loosen the clamping of the workpiece, and then the processed workpiece is removed from the clamping mechanism 6. During the processing, the power mechanism 5 drives a plurality of clamping mechanisms 6 to move synchronously to clamp the workpiece, and the workpiece can be fixed at the central position, thereby improving the accuracy of the subsequent processing of the workpiece by the processing mechanism 10.

[0031] Embodiment Three:

[0032] The difference from the above embodiment is as shown in Figure 1 -Figure 10 , the clamping mechanism 6 includes a workpiece limiting block 61 and a block limiting chuck 63. The workpiece limiting block 61 is slidably installed inside the clamping sliding groove 54, and the block limiting chuck 63 is installed outside the clamping mounting plate 53. A block limiting sliding groove 62 is formed outside the workpiece limiting block 61, and a workpiece fixing clamp block 64 is slidably installed inside the workpiece limiting block 61. An clamp block transmission connecting rod 65 is installed outside the workpiece fixing clamp block 64, and a transmission mounting post 66 is installed outside the clamp block transmission connecting rod 65.

[0033] The outside of the workpiece fixing clamp block 64 is connected to the transmission mounting post 66 through the clamp block transmission connecting rod 65. The outside of the transmission mounting post 66 is slidably installed in the sliding groove inside the transmission turntable 52. The lengths of the clamp block transmission connecting rods 65 on multiple clamping mechanisms 6 are different; When the transmission turntable 52 rotates, it can drive the clamp block transmission connecting rod 65 to move through the transmission mounting post 66 and the clamp block transmission connecting rod 65. When the workpiece fixing clamp block 64 moves, it can drive the workpiece limiting block 61 to move synchronously. When the transmission turntable 52 rotates forward, it can drive the workpiece limiting block 61 to move towards the center of the clamping mounting plate 53. When the transmission turntable 52 rotates reversely, it can drive the workpiece limiting block 61 to move towards the edge of the clamping mounting plate 53.

[0034] The block limiting sliding groove 62 formed on the side surface of the workpiece limiting block 61 is of an inclined structure. The workpiece limiting block 61 is slidably connected to the outside of the block limiting chuck 63 through the block limiting sliding groove 62; 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 chuck 63.

[0035] When the driving turntable 52 rotates forward, it can drive the driving mounting column 66 to move towards the center of the driving turntable 52 through the internal chute and the driving connecting rod 65 of the clamping block. When the driving mounting column 66 moves towards the center of the driving connecting block 55, it can drive the workpiece fixing clamp block 64 to move towards the center of the clamping mounting plate 53. When the workpiece fixing clamp block 64 moves towards the center of the clamping mounting plate 53, it can fix the workpiece to be processed. When the workpiece fixing clamp block 64 moves towards 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 towards the center of the clamping mounting plate 53, the block limiting block 63 can drive the workpiece limiting block 61 to move towards the workpiece by slidingly connecting with the chute on the external block limiting chute 62 of the workpiece limiting block 61. When the workpiece limiting block 61 moves towards the workpiece, it can drive the workpiece to move away from the clamping mounting plate 53. Therefore, when the workpiece fixing clamp block 64 moves towards the center of the clamping mounting plate 53 to fix the workpiece, it can also drive the workpiece limiting block 61 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 driving turntable 52 rotates reversely to drive the driving mounting column 66 to move towards the edge of the clamping mounting plate 53. When the driving mounting column 66 moves towards the edge of the clamping mounting plate 53, it can drive the workpiece fixing clamp block 64 and the workpiece limiting block 61 to move towards the edge of the clamping mounting plate 53. When the workpiece fixing clamp block 64 moves towards the edge of the clamping mounting plate 53, it can loosen the clamping of the workpiece, and then remove the processed workpiece from the workpiece fixing clamp block 64.

[0036] Embodiment 4:

[0037] The difference from the above embodiment is as follows. Please refer to Figure 1 - Figure 10 The connecting component 9 includes a driving connecting rod 91. One end of the driving connecting rod 91 is connected to the outside of the moving base 8, and the other end of the driving connecting rod 91 is connected with a clamping block baffle 92. A connecting clamping block chute 93 is formed inside the driving connecting rod 91, and a driving connecting clamping block 94 is slidably mounted on the outside of the driving connecting rod 91. A clamping block mounting block 95 is installed inside the driving connecting clamping block 94; The driving connecting clamping block 94 is slidably mounted inside the connecting clamping block chute 93 formed inside the driving connecting rod 91 through the clamping block mounting block 95.

[0038] The outside of the driving connecting rod 91 is clamped with the driving connecting groove 56 inside the driving connecting block 55 through the driving connecting clamping block 94. One end of the driving connecting rod 91 connected to the moving base 8 is wider than the end connected to the clamping block baffle 92; When the moving base 8 drives the transmission connecting rod 91 to move, the transmission connecting block 94 can be inserted into the transmission connecting groove 56. When the transmission connecting rod 91 moves, it can drive the transmission connecting block 94 to move to both sides and clamp the transmission connecting block 55 tightly.

[0039] During operation, the moving base 8 can drive the connecting assembly 9 and the processing mechanism 10 to move along the outside of the moving slide rail 7. When the moving base 8 drives the connecting assembly 9 and the processing mechanism 10 to move towards the clamping mechanism 6, the transmission connecting block 94 on the outside of the transmission connecting rod 91 can be inserted into the transmission connecting groove 56. After the transmission connecting block 94 is inserted into the transmission connecting groove 56, the transmission connecting rod 91 continues to move. At this time, the transmission connecting block 94 cannot continue to move under the restriction of the transmission connecting groove 56. During the continuous movement of the transmission connecting rod 91, it can cause the transmission connecting block 94 to move to both sides by extrusion. When the transmission connecting block 94 moves to both sides, it can be more tightly connected to the transmission connecting block 55 on the clamping mounting plate 53. After the transmission connecting rod 91 is connected to the transmission connecting block 55 on the clamping mounting plate 53 through the transmission connecting block 94, 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 conducted through the transmission connecting rod 91. When the vibration can be conducted to each other, it can prevent the appearance of vibration marks on the surface of the workpiece during the processing of the processing mechanism 10, and can also prevent the damage of the processing mechanism 10 during the processing. After the processing is completed, the moving base 8 drives the connecting assembly 9 and the processing mechanism 10 to move away from the clamping mechanism 6. During the movement of the connecting assembly 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 connecting block 94 to move through the block baffle 92. After the transmission connecting block 94 moves, the separation between the connecting assembly 9 and the clamping mechanism 6 can be completed.
