DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0020] See also Figures 1 to 6 A limiting assembly of a rotating platform 100 includes a base 200, on which the rotating platform 100 is arranged, and two workstations are arranged on the rotating platform 100. The rotating platform 100 is driven manually or by a motor to rotate on the base 200. A first limiting plate 301 and a second limiting plate 302 are arranged diagonally on the base 200, and a guiding inclined surface 310 is arranged on the first limiting plate 301 and the second limiting plate 302, and the inclination directions of the guiding inclined surfaces 310 on the first limiting plate 301 and the second limiting plate 302 are opposite. When the rotating platform 100 rotates, its edge contacts the guide slope 310, thereby pressing the first limit plate 301 downward. When the rotating platform 100 completes a 180° rotation so that one of the workstations corresponds to the position of the machine head 201, the rotating platform 100 is opened from above the first limit plate 301 and the second limit plate 302, and the first limit plate 301 and the second limit plate 302 extend out to limit the reverse rotation of the rotating platform 100.

[0021] A first limiting ring 110 is provided on the side of the rotating platform 100 facing the base 200, and a second limiting ring 210 is provided on the side of the base 200 facing the rotating platform 100. The first limiting ring 110 and the second limiting ring 210 are concentrically arranged. When the rotating platform 100 rotates, the rotating platform can drive the first limiting ring 110 to rotate, so that the first limiting ring 110 and the second limiting ring 210 can rotate relative to each other.

[0022] The first limiting ring 110 is provided with a retractable rotating member 130 , and the second limiting ring 210 is provided with a limiting groove 211 corresponding to the rotating member 130 . When the rotating member 130 is embedded in the limiting groove 211 , the relative rotation between the first limiting ring 110 and the second limiting ring 210 is limited.

[0023] Specifically, the first limiting ring 110 is provided with a telescopic groove 111, and a support member 120 is provided in the telescopic groove 111. The support member 120 includes a first plate body 121 and a second plate body 122 which are parallel to each other, and the first plate body 121 and the second plate body 122 are connected by a third plate body 123. The first plate body 121, the second plate body 122 and the third plate body 123 form a mounting groove 132, and a rotating member 130 is installed in the mounting groove 132 through a rotating shaft 131. The rotating member 130 can rotate in the mounting groove 132, and the first part of the rotating member 130 extends out of the mounting groove 132 and rolls with the second limiting ring 210. When the first limiting ring 110 and the second limiting ring 210 rotate relative to each other, the rotating member 130 rolls along the surface of the second limiting ring 210. A first spring 112 is arranged in the telescopic slot 111. The first spring 112 abuts against the support member 120 to push the support member 120 to move toward the second limiting ring 210, so that the rotating member 130 can maintain contact with the second limiting ring 210. A limiting slot 211 is arranged on the side of the second limiting ring 210 facing the rotating member 130. The first limiting ring 110 rotates along the X direction and drives the rotating member 130 to move along the X direction. When the rotating member 130 corresponds to the limiting slot 211, the rotating member 130 is pushed by the first spring 112 to be embedded in the limiting slot 211 and locked with the limiting slot 211, thereby limiting the rotation between the first limiting ring 110 and the second limiting ring 210. The first limiting ring 110 moves along the Y direction and drives the rotating member 130 to move along the Y direction. When the rotating member 130 corresponds to the limiting groove 211, it is embedded in the limiting groove 211. At the same time, a guide groove 212 is also provided on the second limiting ring 210. The guide groove 212 connects the side of the second limiting ring 210 facing the rotating member 130 and the bottom surface of the limiting groove 211, so that when the rotating member 130 continues to move along the Y direction, it can move along the guide groove 212 toward the surface of the second limiting member, so that the first limiting ring 110 and the second limiting ring 210 can rotate relative to each other. Through the cooperation between the rotating member 130 and the limiting groove 211, the rotating platform 100 can only rotate in one direction, thereby preventing the rotating platform 100 from rotating in the opposite direction and causing damage to the equipment.

[0024] Two fixed blocks 320 are diagonally arranged on the base 200, and the fixed blocks 320 are provided with grooves 321. The first limiting plate 301 and the second limiting plate 302 are respectively placed in the grooves 321 of the two fixed blocks 320. A second spring 330 is arranged in the groove 321. The spring can make the limiting plate 300 extend from the groove 321 to limit the rotation of the rotating platform 100, and also facilitate the positioning of the workpiece and the machine head 201.

[0025] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
