[0018] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0019] Embodiment 1

[0020] like Figures 1 to 6 As shown, a CNC machine tool assembly line processing system includes machine tools a1, b2, c3 and d4. The machine tools a1 and d4 are both provided with a lifting assembly 5, the lower end of the lifting assembly 5 is provided with a rotating assembly 6, and the rotating assembly 6 is provided with a plurality of clamping assemblies 7. The machine tools b2 and c3 are both provided with a fixing assembly 8. The lifting assembly 5 drives the rotating assembly 6 to perform lifting motion, and the rotating assembly 6 drives the clamping assembly 7 to perform lifting motion to clamp a part 9, and the rotating assembly 6 drives the part 9 to enter the next station for processing.

[0021] It is worth mentioning here that the lifting component 5 drives the rotating component 6 to perform lifting motion, the rotating component 6 drives the clamping component 7 to perform lifting motion to clamp the part 9, and the rotating component 6 drives the part 9 to enter the next workstation for processing, which improves work efficiency, eliminates the need for manual loading and unloading of parts, and improves the product qualification rate.

[0022] like Figure 2 As shown, the lifting assembly 5 includes a cylinder body 51 disposed on the machine tool a1 or the machine tool d4 and a piston rod 52 driven by the cylinder body 51 .

[0023] like Figure 4As shown, the rotating assembly 6 includes a guide rail 61 arranged at the lower end of the piston rod 52, a driving member 62 arranged on the guide rail 61, a gear a63 driven by the driving member 62, a gear b64 arranged at the other end of the guide rail 61, and a chain 65 arranged between the gear a63 and the gear b64.

[0024] like Figure 3 As shown, the clamping assembly 7 includes a support member 71 arranged on the chain 65, an inclined block 72 slidably arranged in the support member 71, and a clamping block 73 slidably arranged in the support member 71.

[0025] In this example, the part 9 is clamped by the clamping block 73 and the inclined block 72 .

[0026] like Figure 5 As shown, a return spring 74 is arranged between the inclined block 72 and the support member 71, a sliding cavity 75 is opened in the support member 71, a sliding groove 76 for sliding the clamping block 73 is arranged at the upper end of the sliding cavity 74, and a spring 77 is arranged between the inclined block 72 and the clamping block 73.

[0027] In this example, the reset spring 74 allows the inclined block 72 to be reset after being pressed in, and the spring 77 allows the clamping block 73 to be reset after sliding.

[0028] like Figure 3 As shown, the fixing assembly 8 includes a cylinder 81 arranged on the machine tool b2 or the machine tool c3, a piston rod 82 driven by the cylinder 81, and a clamping block 83 arranged on the upper end of the piston rod 82.

[0030] like Figure 2 , 3 As shown, both the machine tool b2 and the machine tool c3 are provided with a moving platform 21 and a processing table 22 .

[0031] The working process is as follows: The part 9 is placed on the placement table 11 of the machine tool a1 by the manipulator, and the cylinder 51 drives the piston rod 52 to descend, thereby driving the rotary assembly 6 to descend; The inclined block 72 is pressed by the outer side of the part 9 to slide into the sliding cavity 75, driving the clamping block 73 to slide on the sliding groove 76 and slide into the sliding cavity 75 together with the inclined block 72. At this time, the return spring 74 is compressed and the spring 77 is stretched. When the inclined block 72 passes over the part 9, the upper end surface of the inclined block 72 contacts the part 9 and rebounds under the action of the return spring 74. The clamping block 73 also rebounds under the action of the spring 77 to clamp the part 9. The cylinder body 51 drives the piston rod 52 to rise, drives the rotary assembly 6 to rise, thereby drives the part 9 to rise, and the driving member 62 drives the gear a63 to rotate, thereby drives the chain 65 to make a rotary motion, and drives the clamping assembly 7 and the part 9 to enter the next station through the chain 65, and reciprocates in sequence to realize assembly line processing.
