For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] As Figures 1 to 6As shown in the figure, the automated opening, closing and rotating mechanism of this embodiment includes: a support base 1, a rotating ring rotatably arranged on the support base 1, and a clamping device arranged on one side of the rotating ring. The rotating ring includes an upper half ring 21 and a lower half ring 22 which are hinged together. The upper half ring 21 and the lower half ring 22 are spliced to form the rotating ring. An outer guide wheel 11 is arranged on the support base 1, and the rotating ring is rotatably supported on the outer guide wheel 11. A gear ring 23 is arranged on the rotating ring, and a rotating drive mechanism 12 cooperating with the gear ring 23 is arranged on the support base 1.

[0028] An inner guide wheel 13 is arranged on the support base 1, and the inner guide wheel 13 presses against the inner wall of the rotating ring. The combination of the inner and outer guide wheels can ensure the accuracy of the rotating ring during operation and reduce errors. The guide wheel structure is a rotatable roller, and its shape matches the structure of the rotating ring. To avoid jamming, a clearance installation method is adopted, with a certain redundant space.

[0029] A rotating link 14 is hinged on the support base 1. One end of the rotating link 14 is provided with an opening and closing drive cylinder 15, and the other end is provided with a guide pulley 16. The guide pulley 16 is slidably arranged on the rotating ring; the guide pulley 16 is rotatably matched with the rotating link 14. By driving the rotating link 14 to rotate through the opening and closing drive cylinder 15, the guide pulley 16 opens the upper half ring 21. The principle is the same when closing.

[0030] A lock pin drive assembly 17 is arranged on the support base 1. Through holes are provided on one side of the upper half ring 21 and the lower half ring 22. The lock pin is driven by the lock pin drive assembly 17 to insert into the through holes to realize the splicing of the upper half ring 21 and the lower half ring 22. After the upper half ring 21 and the lower half ring 22 are assembled, a lock pin needs to be inserted to prevent the rotating ring from separating during operation. The lock pin drive assembly 17 includes a clamping cylinder and a telescopic cylinder, which can realize the function of clamping and inserting the lock pin into the through hole, and at the same time can realize the function of clamping and removing the lock pin from the through hole.

[0031] The clamping device includes a mounting plate 31. The mounting plate 31 is connected to the lower half ring 22. A clamping slide rail 32 is arranged on the mounting plate 31. A clamping arm 33 is slidably arranged on the clamping slide rail 32. A bidirectional lead screw mechanism 34 is arranged through the clamping arm 33. The clamping device rotates with the rotating ring and is used to clamp the columnar product 100. By driving the clamping arm 33 to move simultaneously through the bidirectional lead screw mechanism 34, the clamping of the columnar product 100 is realized.

[0032] A synchronous slide rail assembly 35 is arranged between the clamping arms 33, and a connecting arm 36 is arranged between the clamping arms 33 and the synchronous slide rail assembly 35. Since the two clamping arms 33 may have different degrees of wear, if the wear is severe, the clamping arms 33 will sway left and right on the lead screw, and the center point will deviate. The purpose of adding the synchronous slide rail is to use the synchronous slide rail as the center position. The center position of the synchronous slide rail is constant, and the connecting arm 36 pulls the clamping arms 33 on both sides to move according to the center point, thus eliminating the gap.

[0033] A lead screw drive mechanism 37 is arranged on the support base 1. The lead screw drive mechanism 37 is slidably arranged on one side of the support base 1, and the lead screw drive mechanism 37 is connected with a clutch cylinder 18.

[0034] A wear-resistant layer 38 is arranged on the clamping arms 33. The wear-resistant layer 38 can be arranged integrally or locally, which can avoid abrasion on the surface of the columnar product 100 during the clamping process.

[0035] A clamping cylinder 19 is arranged on one side of the support base 1. The clamping cylinder 19 is arranged outside the rotating ring. Before processing the columnar product 100, the rotating ring is fixed by the clamping cylinder 19 to prevent shaking during the processing and causing errors.

[0036] During use, the mechanism of this embodiment is opened to the Figure 3 shown state, and the columnar product 100 is placed in the working position. The opening and closing drive cylinder 15 drives the rotating link 14 to rotate, so that the guide pulley 16 closes the upper half ring 21. The lock pin drive assembly 17 works, and the pin is inserted into the through hole, so that the upper half ring 21 and the lower half ring 22 are in a closed state. The clutch cylinder 18 pushes the lead screw drive mechanism 37 to be connected with the double lead screw mechanism 34. Driven by the lead screw drive mechanism 37, the lead screw rotates, and the clamping arms 33 move towards the middle to achieve clamping. The function of the synchronous slide rail assembly 35 is to make the clamping arms 33 on both sides synchronously centered. After clamping, the clutch cylinder 18 disconnects the lead screw drive mechanism 37 from the double lead screw mechanism 34 to give way for subsequent rotation. Before processing, the rotation drive mechanism 12 drives the gear to rotate, and the rotating ring rotates through the meshing of the gear and the gear ring 23. After rotating to the appropriate position, the rotating ring is clamped by the clamping cylinder 19 to prevent shaking during the processing.

[0037] After processing is completed, the lock pin drive assembly 17 works, pulls out the pin inserted into the through hole, and the opening and closing drive cylinder 15 drives the rotating link 14 to rotate, so that the guide pulley 16 opens the upper half ring 21, the clamping device releases the restriction on the columnar product 100, and the columnar product 100 can be taken out.

[0038] The automatic opening and closing rotating mechanism of the present utility model has strong compatibility. By combining the rotating and opening / closing structures, it can clamp products and simultaneously achieve rotation, adapting to various sizes and being convenient to use.

[0039] The above are only embodiments of the present utility model. Specific structures and common knowledge such as characteristics well known in the art are not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
