[0018] Please combine Figure 1 and Figure 2 As shown, the transverse movement assembly 2 includes a transverse movement motor 21, a coupling 22, a screw rod 24, a transverse movement guide rail 26, a connecting block 23 and a rotating mounting plate 25.

The transverse movement motor 21 drives the screw rod 24 to rotate, driving the connecting block 23 to move, thereby driving the rotating mounting plate 25 to move along the transverse movement guide rail 26, thereby driving the rotating assembly 3 to move.

[0019] Specifically, the rotating assembly 3 includes a rotating motor 31, a speed reducer 32, a driving wheel 33, a driven wheel 35, a rotating shaft 36, a bearing 37, a rotating connection seat 38 and an electrical slip ring 34. The rotating motor 31 is connected to the driving wheel 33 through the speed reducer 32. The driving wheel 33 and the driven wheel 35 are meshed. The bearing 37 is mounted on the rotating mounting plate 38. The rotating shaft 36 passes through the bearing 37 so that the rotating shaft 36 can rotate freely relative to the bearing 37. The driven wheel 35 is fixed on the rotating shaft 36. The electrical slip ring 34 is mounted on the upper end of the rotating shaft 36. The wires of the rotating motor 31 pass through the electrical slip ring 34 to avoid twisting of the wires and make the wiring simpler. The rotating connection seat 38 is mounted on the lower end of the rotating shaft 36. The rotating connection seat 38 is fixed to the variable pitch clamp assembly 4. The rotating motor 31 drives the driving wheel 33 to rotate, driving the driven wheel 35 to rotate, thereby rotating the rotating shaft 36 and driving the rotating connection seat 38 to rotate.

[0020] like Figure 3As shown, the variable pitch jaw assembly 4 includes a jaw guide rail 44, a jaw bracket 41, at least three jaw structures, a connecting rod structure 49, a first rodless cylinder structure 42 and a second rodless cylinder structure 43. In the present embodiment, four jaw structures are provided, namely a first jaw structure 45, a second jaw structure 46, a third jaw structure 47 and a fourth jaw structure 48. The first rodless cylinder structure 42, the second rodless cylinder structure 43 and the jaw guide rail 44 are installed on the jaw bracket 41, and the connecting rod structure 49 connects the first jaw structure 45, the second jaw structure 46, the third jaw structure 47 and the fourth jaw structure 48 in sequence respectively. The first rodless cylinder structure 42 drives the first jaw structure 45 to move along the jaw guide rail 44, and the second rodless cylinder structure 43 drives the fourth jaw structure 48 to move along the jaw guide rail 44, thereby adjusting the spacing between the first jaw structure 45, the second jaw structure 46, the third jaw structure 47 and the fourth jaw structure 48.

[0021] The first clamping jaw structure 45, the second clamping jaw structure 46, the third clamping jaw structure 47 and the fourth clamping jaw structure 48 have the same structure. In order to avoid redundant description, in this embodiment, only the first clamping jaw structure 45 is used as an example for description. The first clamping jaw structure 45 includes a cylinder mounting seat 451, a clamping jaw cylinder 452 and a clamping jaw 453. The cylinder mounting seat 451 moves along the guide rail 44. The clamping jaw cylinder 452 is mounted on the cylinder mounting seat 451. The clamping jaw cylinder 452 drives the two clamping jaws 453 to move relative to each other. A limiting column 454 is also provided on the cylinder mounting seat 451. The limiting column 454 is installed on one side of the cylinder mounting seat 451 to avoid collision between two adjacent cylinder mounting seats 451.

[0022] The connecting rod structure 49 includes a connecting rod 491 and a connecting rod limit block 492. One end of the connecting rod 491 is fixed on a cylinder mounting seat of one clamping structure, and the connecting rod is inserted into a cylinder mounting seat of another clamping structure. The connecting rod limit block is installed on the other end of the connecting rod.

[0023] The structures of the first rodless cylinder structure 42 and the second rodless cylinder structure 43 are the same. In order to avoid redundancy, in the present embodiment, only the first rodless cylinder structure 42 is taken as an example for explanation. The first rodless cylinder structure 44 includes a guide rod 422, a rodless cylinder 421 and a guide rod mounting seat 423. The guide rod mounting seat 423 is installed at both ends of the guide rod 422, and the rodless cylinder 421 moves along the guide rod 422.

[0024] When the above-mentioned variable-pitch clamping jaw assembly 4 is used to reduce the spacing, the second rodless cylinder structure 43 drives the fourth clamping jaw structure 48 to move along the clamping jaw guide rail 44, and the fourth clamping jaw structure 48 pushes the first clamping jaw structure 45, the second clamping jaw structure 46 and the third clamping jaw structure 47 to move closer to each other along the connecting rod structure 49, so that the clamping jaw structures are concentrated on the left side of the clamping jaw bracket 41, thereby reducing the spacing between the clamping jaw structures; the first rodless cylinder structure 42 drives the first clamping jaw structure 45 to move along the clamping jaw guide rail 44, and the first clamping jaw structure 45 pushes the second clamping jaw structure 46, the third clamping jaw structure 47 and the fourth clamping jaw structure The structures 48 are close to each other along the connecting rod structure 49, so that the clamping structures are concentrated on the right side of the clamping bracket 41, thereby reducing the distance between the clamping structures; the first rodless cylinder structure 42 drives the first clamping structure 45 to move toward the middle along the clamping guide rail 44, and the second rodless cylinder structure 43 drives the fourth clamping structure 48 to move toward the middle along the clamping guide rail 44. The first clamping structure 45 pushes the second clamping structure 46 to approach the middle along the connecting rod structure 49, and the fourth clamping structure 48 pushes the third clamping structure 47 to approach the middle along the connecting rod structure 49, thereby reducing the distance between the clamping structures.

[0025] When the spacing needs to be enlarged, the first rodless cylinder structure 42 drives the first clamping jaw structure 45 to move along the clamping jaw guide rail 44 or the second rodless cylinder structure 43 drives the fourth clamping jaw structure 48 to move along the clamping jaw guide rail 44, and drives the adjacent clamping jaw structure to move through the connecting rod structure 49, thereby achieving enlarged spacing.

[0026] The above-described embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent application scope of the present invention should be included in the scope of the patent application of the present invention.
