[0016] In order to make the patent purposes, technical schemes and advantages of the utility model clearer and more understandable, the utility model is further described in detail below by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0017] In order to explain the technical scheme of the utility model, the following specific embodiments are used for description.

[0018] Only parts related to the embodiments of the utility model are shown for the convenience of description.

[0019] Combination Figures 1-4 As shown in the drawings, the metal cover processing turntable comprises a machine table 1, a rotatable rotating disc 2 is arranged on the machine table 1, an upper feeding conveying table 3 and a lower feeding conveying table 4 are arranged on the two sides of the rotating disc 2 respectively, a vertical frame 5 is arranged between the upper feeding conveying table 3 and the lower feeding conveying table 4, a linear motor 6 is arranged on the vertical frame 5, a moving frame 7 is arranged on the driving end of the linear motor 6, a lifting plate 8 which can move up and down is arranged on the moving frame 7, a pair of suction cups 9 is arranged on the lifting plate 8, a plurality of clamping assemblies are arranged on the rotating disc 2 along the circumferential direction, the clamping assembly comprises a base 10, a pair of left and right clamping plates are arranged on the base 10, the left clamping plate is marked as 111, and the right clamping plate is marked as 112. The left clamping plate 111 is slidingly installed, and the right clamping plate 112 is fixedly installed. A sliding seat 12 is arranged on the side wall of the base 10. A connecting seat 13 is slidingly arranged on the sliding seat 12. The left clamping plate 111 is arranged on the connecting seat 13. A pair of guide nuts 14 are penetrated into the sliding seat 12. The guide nuts 14 are fixedly arranged on the connecting seat 13. A spring 15 is arranged between the connecting seat 13 and the sliding seat 12 on the guide nut 14. The connecting seat 13 is downwardly provided with a clamping plate 151 which penetrates out of the rotating disc 2. The machine table 1 is provided with a pushing assembly for pushing the clamping plate 151 to move.

[0020] In the embodiment, the machine table is provided with a feeding position and a processing position, and the feeding position and the processing position are respectively provided with a pushing assembly and a processing mechanism. In the actual processing process, all the clamping assemblies rotate together with the rotating disc. In the drawings, the number of the clamping assemblies is eight. Each clamping assembly clamps a metal disc.

[0021] When the clamping assembly rotates to the processing position, the rotating disc stops rotating, and the processing mechanism processes the metal disc at this position. At the same time, the metal disc on the clamping assembly at the feeding position has been processed, and the clamping assembly releases the metal disc under the driving of the pushing assembly. Before this, the right suction cup is located directly above the feeding position, and the left suction cup is located at a taking position of the upper feeding conveying table. The taking position is provided with a metal disc to be processed. The lifting plate moves downward until the left and right suction cups respectively suck the metal disc to be processed and the processed metal disc. Then the lifting plate moves upward by a small distance. The linear motor drives the moving frame to move rightward by one position. At this time, the metal disc to be processed is located at the feeding position, and the processed metal disc is located at a discharging position of the lower feeding conveying table. The lifting plate moves downward again. The metal disc to be processed falls on the clamping assembly at the feeding position, and the processed metal disc falls on the lower feeding conveying table. Then the lifting plate is reset.

[0022] The processed metal disc is discharged under the conveying of the lower feeding conveying table. Then the pushing assembly is reset. The clamping assembly at the feeding position clamps the metal disc to be processed. Then the rotating disc continues to rotate by one position, and the next clamping assembly rotates to the feeding position.

[0023] When the clamping assembly at the upper loading position needs to release the metal disc, the push assembly pushes the clamping plate to move left, the connecting seat moves together with the clamping plate, and the spring is gradually compressed. When the left clamping plate slides a small distance to the left, the two clamping plates release the clamping of the metal disc, and the metal disc is transferred. After the metal disc to be processed is placed on the two clamping plates, the push assembly resets and no longer pushes the clamping plate. The two clamping plates clamp the metal disc under the action of the spring. Then the rotating disc rotates one position.

[0024] In the structure, as Figure 1 , the lifting plate 8 is slidingly installed on the moving frame 7, the moving frame 7 is provided with a lifting cylinder 21, and the driving shaft of the lifting cylinder 21 is connected with the lifting plate 8. The lifting plate moves vertically through the lifting cylinder.

[0025] As a preferred structure, as Figure 2 , the rotating disc 2 is provided with a notch 16 corresponding to each clamping plate 151, the clamping plate 151 is located in the notch 16, and the lower side of the clamping plate 151 is a slope. The push assembly includes a fixed frame 21 installed on the machine table 1, the fixed frame 21 is provided with a push cylinder 22, the push cylinder 22 is provided with a push seat 23, and the push seat 23 is rotatably provided with a push wheel 24.

[0026] When one of the clamping assemblies rotates to the upper loading position, the push cylinder drives the push wheel to move upward, the push wheel pushes the slope of the clamping plate upward, and the clamping plate drives the connecting seat to stably move a small distance to the left under the guidance of the slope until the two clamping plates release the metal disc. In the above structure, the notch plays a role of limiting the clamping plate and avoiding the clamping plate.

[0027] In addition, as Figures 3-4 , the base 10 is provided with a guide groove 17, the bottom surface of the right clamping plate 112 is formed with a guide head 18, the guide head 18 is located in the guide groove 17, a row of threaded holes 19 are formed in the guide groove 17, and a locking nut (not shown in the figure) is penetrated into the right clamping plate 112 and screwed into the threaded holes. The left clamping plate 111 is provided with a pair of stepped long grooves 20, and a fixing nut (not shown in the figure) is screwed into the long grooves 20 and screwed into the connecting seat 13.

[0028] In the structure, the installation positions of the left and right clamping plates on the base can be finely adjusted to adapt to metal plates of different sizes. If the position of the left clamping plate is to be adjusted, first loosen the fixing nut, then adjust the position of the left clamping plate on the connecting seat, and then tighten the fixing nut after the adjustment is completed. Similarly, if the position of the right clamping plate is to be adjusted, first loosen the locking nut, then move the right clamping plate, the guide head slides in the guide groove during the movement of the right clamping plate, the movement of the right clamping plate is more stable under the guidance of the guide head, and then the locking nut is screwed into the threaded hole in the corresponding position after the right clamping plate is moved into position.

[0029] In the above structure, the long groove 20 is in a stepped shape. Figure 3 That is, the long groove 20 includes a shallow groove 201, and a guide groove 202 is formed in the shallow groove 201, and the width of the guide groove is slightly smaller than that of the shallow groove. When the end of the fixing nut is screwed into the connecting seat, the nut of the fixing nut is located in the shallow groove at this time. In this way, the entire clamping assembly can look more beautiful.

[0030] The above only describes the preferred embodiments of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
