DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See also Figures 1 to 5The embodiment of the present application provides a uniform high-speed carburizing device for screws. The device can be used for high-temperature heating carburizing and ion carburizing. When used for high-temperature heating carburizing, a heating device is installed in the box; when used for ion carburizing, a corresponding device is installed in the box, including a box 2, a box cover 3 is provided on the box 2, and a plurality of connecting rods 4 are connected in a rotating, sliding and sealing manner in the box 2. Openings corresponding to the connecting rods 4 are provided on the box 2, and sealing rings are installed in the openings to realize the rotating, sliding and sealing connection between the box 2 and the connecting rods 4. The spacing between the connecting rods 4 is less than the diameter of the screw head and greater than the diameter of the screw rod. A gear 5 is installed on the connecting rod 4, and a gear 5 is installed on the box 2. A rack 6 is slidably connected, and the rack 6 is meshed with the gear 5. A linear actuator 7 is installed on the box body 2. The linear actuator 7 can be an electric cylinder, and the output end of the linear actuator 7 is connected to the rack 6. A linear actuator 3 10 is installed on the box body 2. The linear actuator 3 10 can be an electric cylinder, and a connecting frame 11 is installed on the output end of the linear actuator 3 10. The linear actuator 3 10 and the connecting frame 11 are arranged opposite to each other. A plurality of connecting rods 4 are rotatably connected to the connecting frame 11. The connecting rod 4 can drive the connecting rod 4 to move when the connecting frame 11 moves through a bearing structure. The connecting rods 4 rotatably connected on the connecting frames 11 on different sides are staggered.

[0022] In this embodiment, after the box cover 3 is removed, the screw is put into the box body 2, and the screw is received by the connecting rod 4. Then, the rack 6 is driven to move by the linear actuator 1 7, thereby driving the gear 5 on the connecting rod 4 to rotate, so that the screw received by the connecting rod 4 is in a state where the screw rod is facing downward and the screw head is stuck by the adjacent connecting rod 4. After that, the box cover 3 is covered for carburizing. During carburizing, the connecting frame 11 is driven to move by the linear actuator 3 10, and a number of connecting rods 4 are rotatably connected to the connecting frame 11, so that the connecting frame 11 can drive the connecting rod 4 to move horizontally. The connecting rods 4 rotatably connected to the connecting frames 11 arranged opposite to each other on both sides of the box body 2 are staggered, so that when the connecting frames 11 on both sides pull the connecting rods 4, the adjacent connecting rods 4 move in different directions, so that the screws stuck by the adjacent connecting rods 4 can rotate, further improving the uniformity of carburizing on the screw surface.

[0023] In some embodiments, in order to facilitate clamping of the connecting rod 4 and prevent the connecting rod 4 from rotating when the connecting frame 11 drives the connecting rod 4 to slide, a plurality of through holes 12 are provided on the connecting frame 11, and the through holes 12 are matched with the connecting rod 4.

[0024] In some embodiments, in order to facilitate the clamping of the connecting rod 4, a linear actuator 4 13 is installed on the box body 2. The linear actuator 4 13 can be an electric cylinder. A clamping frame 14 is slidably connected to the box body 2. The output end of the linear actuator 4 13 is connected to the clamping frame 14. A slide groove 15 is provided on the clamping frame 14. A slider 16 is slidably connected in the slide groove 15. The slider 16 is arranged in cooperation with the through hole 12. The clamping frame 14 is driven to move upward by the linear actuator 4 13, so that the slider 16 on the clamping frame 14 can abut and rub against the connecting rod 4 through the through hole 12. After that, when the connecting frame 11 drives the connecting rod 4 to move, the slider 16 slides in the slide groove 15 along with the connecting frame 11.

[0025] In some embodiments, in order to protect the slider 16, a friction block 17 is installed on the top of the slider 16. The friction block 17 abuts against the connecting rod 4.

[0026] In some embodiments, in order to further improve the clamping effect of the friction block 17, the top of the friction block 17 is set to be an arc surface.

[0027] In some embodiments, in order to lift or lower the box cover 3, a handle 18 is provided on the box cover 3.
