DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides a technical solution: a material conveying device for bearing production, including a transport box 1, a material conveying device 2 inside the transport box 1, and a placement part 21;

[0025] The placement part 21 includes an extrusion plate 211, a connecting rod 213 and a double threaded screw 214. The bottom surface of the double threaded screw 214 is rotatably connected to the inner wall of the transport box 1 through a bearing seat. The outer surface of the middle extrusion plate 211 is provided with a groove. The outer surface of the connecting rod 213 extends into the groove and is hinged to the inner wall of the extrusion plate 211. The placement part 21 also includes a limiting shell 212 and a threaded sleeve 215.

[0026] The bottom surface of the limiting shell 212 is fixedly connected to the inner wall of the transport box 1, and the inner wall of the middle limiting shell 212 is slidably connected to the outer surface of the connecting rod 213.

[0027] The threaded sleeve 215 is threaded onto the outer surface of the double-threaded screw 214. The outer surface of the connecting rod 213 is hinged to the outer surface of the threaded sleeve 215. By setting up the extrusion plate 211, the limiting shell 212, the connecting rod 213, the double-threaded screw 214, and the threaded sleeve 215, in use, the bearing is sleeved on the outer surface of the limiting shell 212 to position the bearing. By rotating the double-threaded screw 214, the upper and lower sleeves 215 are brought closer to each other. The connecting rod 213 is used to push the extrusion plate 211 to move and adjust the width between the extrusion plates 211. Since the middle extrusion plate 225 is connected to the front and rear extrusion plates 211 through the limiting slider 226 and the translation plate 225, the middle extrusion plate 225 drives the front and rear extrusion plates 225 to move together, which facilitates the installation and positioning of bearings of different diameters.

[0028] The transport container 1 is equipped with a lifting unit 22 inside;

[0029] The lifting part 22 includes a U-shaped rod 221, a slide rod 223 and a return frame 224. The front of the U-shaped rod 221 is fixedly connected to the back of the return frame 224, and the outer surface of the slide rod 223 is fixedly connected to the inner wall of the return frame 224. The lifting part 22 also includes a limiting slide rod 222, a translation plate 225, a spring 227, a limiting member 228 and a limiting slider 226.

[0030] The rear end of the translation plate 225 extends into the inside of the U-shaped frame 224 and slides on the outer surface of the slide rod 223. The outer surface of the translation plate 225 is slidably connected to the inner wall of the U-shaped frame 224. The outer surface of the limiting slider 226 is fixedly connected to the outer surface of the translation plate 225. A limiting groove is opened on the outer surface of the extrusion plate 211. The outer surface of the limiting slider 226 extends into the limiting groove and is slidably connected to the inner wall of the limiting groove.

[0031] The bottom surface of the U-shaped rod 221 is provided with a groove, and the outer surface of the top end of the limiting slide rod 222 extends into the groove and slides in connection with the inner wall of the groove. The bottom surface of the limiting slide rod 222 is fixedly connected to the inner wall of the transport box 1. By setting up the U-shaped rod 221, the limiting slide rod 222, the slide rod 223, the return frame 224, the translation plate 225, and the limiting slider 226, the device can lift the U-shaped rod 221 forward, which will drive the return frame 224 to move upward, so that the moving plate 225 will lift the bearing upward, making it easier to pick up the bearing at the bottom. The limiting slider 226 makes it easy for the translation plate 225 and the extrusion plate 211 to always maintain a moving distance. The translation plate 225 moves with the extrusion plate 211 and will not separate from the extrusion plate due to bearings of different sizes placed in the device.

[0032] A slot is provided on the back of the U-shaped rod 221. The outer surface of the limiting member 228 slides through the inner wall of the transport box 1 and extends into the slot. The rear end of the spring 227 is fixedly connected to the inner wall of the limiting member 228, and the front end of the spring 227 is fixedly connected to the back of the transport box 1. By setting the spring 227 and the limiting member 228, the elastic force of the spring 227 is used to make the front end of the limiting member 228 engage in the slot on the back of the U-shaped rod 221, which facilitates the positioning of the U-shaped rod 221 and keeps the translation plate 225 at a fixed height, making it easy to remove the bearing.

[0033] In use, rotating the double-threaded screw 214 drives the upper and lower threaded sleeves 215 to move closer together. Through the connecting rod 213, the extrusion plate 211 is pushed to move, so that the extrusion plate 211 extrudes the inside of the bearing, thereby positioning the bearing. When unloading, first remove the upper bearing, then pull the limiting member 228 backward. The limiting member 228 no longer positions the U-shaped rod 221, and pull the U-shaped rod 221 upward. The U-shaped rod 221 drives the return frame 224 and the translation plate 225 to move upward. The translation plate 225 lifts the bearing, which can then be picked up.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
