[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1-9 The utility model provides a technical solution: a connecting rod logistics caching and conveying device, including a frame 1, with power shafts rotatably connected on both sides of the frame 1, each power shaft is installed with a sprocket, and the two sprockets are connected by a chain unit 6, and a motor 3 for driving one of the power shafts to rotate is provided on the frame 1; it also includes multiple groups of mounting plates 4 for mounting workpiece bodies 5, each mounting plate 4 is mounted on the chain unit 6 through a corresponding mounting piece; a positioning mechanism for fixing the workpiece body 5 is provided on the mounting plate 4; the workpiece body 5 includes a rod body and a rod head, and the positioning mechanism includes a first positioning portion for positioning the rod head, and also includes a second positioning portion for positioning the rod body.

[0041] Specifically, the connecting rod logistics buffer conveying device includes a frame 1, and the two sides of the frame 1 are respectively connected to a power shaft for rotation. A sprocket is installed on each power shaft, and the two sprockets are connected by a chain unit 6. The frame 1 is provided with a motor 3 for driving one of the power shafts to rotate. At this moment, when the conveying device needs to be used, the motor 3 is started, and the motor 3 will drive the sprocket to rotate through the power shaft, so that the chain unit 6 slides on the frame 1 to facilitate the conveying of the workpiece. It also includes multiple groups of mounting plates 4 for mounting the workpiece body 5, each mounting plate 4 is respectively mounted on the chain unit 6 through a corresponding mounting piece, and when the chain unit 6 moves, it drives the mounting plate 4 to slide to realize the conveying of the workpiece body 5. The mounting plate 4 is provided with a positioning mechanism for fixing the workpiece body 5. The positioning mechanism can limit the workpiece body 5 to the mounting plate 4, avoiding the risk of shaking or even falling off of the workpiece body 5 during the conveying, thereby improving the practicality of the conveying device. The workpiece body 5 includes a rod body and a rod head. Specifically, when the workpiece body 5 is not connected, the rod head and the rod body are in a separated state. The positioning mechanism includes a first positioning portion for positioning the rod head and a second positioning portion for positioning the rod body. Therefore, when the workpiece body 5 needs to be transported, the workpiece body 5 is installed at a predetermined position. At this time, the first positioning portion restrains the rod head, and the second positioning portion restrains the rod body. This can improve the stability of the workpiece body 5 during installation, avoid the risk of shaking or even falling off the workpiece body 5 during transportation, and thus improve the practicality of the transportation device.

[0042] In the embodiment provided by the present invention, the first positioning portion includes a first positioning block 7 and a protective block 14 provided on the mounting plate 4 , and the rod head is installed between the first positioning block 7 and the protective block 14 , at which point the rod head will be restricted.

[0046] In the embodiment provided by the present invention, elastic portions are provided at the abutment points between the first positioning portion and the rod head, and at the abutment points between the second positioning portion and the rod body. The provision of the elastic portions can protect the workpiece body 5 to a certain extent, and can also be used for positioning and subsequent conveying operations of workpiece bodies 5 of different sizes, further expanding the applicability of the conveying device.

[0047] Conventional chain drives utilize wear-resistant strips rolling on chain rollers, guided by chain plates. This guide structure causes significant wear on the chain. The lower guide is provided by tooling plates, which rub against green ultra-high molecular weight polyethylene wear-resistant strips mounted on the side support plates. This structure also causes significant wear on the wear strips.
