[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0021] Reference Figure 1-3 As shown, this utility model provides a bolt thread rolling device, including a frame 1, on which two thread rolling rollers 1.1 are arranged. One thread rolling roller 1.1 is rotatably connected to the frame 1, and the other thread rolling roller 1.1 is slidably connected to the frame 1. It also includes a transmission assembly, which is arranged on the two thread rolling rollers 1.1. During the stroke of one thread rolling roller 1.1 on the frame 1, the thread rolling rollers 1.1 rotate synchronously, thereby realizing the thread rolling of bolts with different outer diameters.

[0022] The transmission assembly includes a pulley 1.2 coaxially fixedly connected to one of the thread rolling rollers 1.1 and a radial connector coaxially fixedly connected to the other thread rolling roller 1.1. A conveyor belt 1.4 is sleeved between the radial connector and the pulley 1.2.

[0023] The radial connector includes a central wheel 1.3, and multiple arc-shaped blocks 1.31 and multiple transmission blocks 1.32 are slidably connected to the radial direction of the central wheel 1.3. The arc-shaped blocks 1.31 and the transmission blocks 1.32 are arranged alternately in sequence, and each arc-shaped block 1.31 and each transmission block 1.32 is slidably connected to each other in pairs.

[0024] Each arc-shaped block 1.31 is connected to the central wheel 1.3 by a spring 1.303.

[0025] A sleeve 1.50 is coaxially sleeved on the center wheel 1.3, and the sleeve 1.50 is connected to the frame 1 by a hydraulic rod 1.5.

[0026] Specifically, such as Figure 1As shown, two thread rolling rollers 1.1 are mounted on the frame 1. One of them is rotatably connected to the frame 1, and the other thread rolling roller 1.1 moves radially in relation to the rotating thread rolling roller 1.1. The centers of the two thread rolling rollers 1.1 are located on the same horizontal line. The thread rolling roller 1.1 rotatably connected to the frame 1 is driven by a motor 1.6. A transmission assembly is provided between the two thread rolling rollers. The transmission assembly includes a pulley 1.2 coaxially fixedly connected to the motor 1.6 and a central wheel 1.3 coaxially fixedly connected to the other thread rolling roller 1.1. The central wheel 1.3 has multiple first grooves 1.301 and multiple second grooves 1.302 radially circumferentially arranged. Each first groove 1.301 and each second groove 1.302... The slides 1.302 are arranged alternately. A spring 1.303 is fixedly connected in each second slide 1.302, and an arc-shaped block 1.31 is slidably connected in each second slide 1.302. The other end of each spring 1.303 is fixedly connected to its corresponding arc-shaped block 1.31. A transmission block 1.32 is slidably connected in each first slide 1.301. The arc-shaped blocks 1.31 corresponding to each transmission block 1.32 are slidably connected to each other. A conveyor belt 1.4 is sleeved between the outside of each arc-shaped block 1.31 and the pulley 1.2. A sleeve 1.50 is coaxially sleeved at the shaft of the central wheel 1.3. The sleeve 1.50 is connected to the frame 1 through a hydraulic rod 1.5.

[0027] During use, the hydraulic rod 1.5 drives the thread rolling rollers 1.1, which are slidably connected to the frame 1, to move, so that the distance between the outer diameters of the two thread rolling rollers 1.1 matches the outer diameter of the bolt. Since each arc block 1.31 is connected to the center wheel 1.3 by a spring 1.303, under the action of the conveyor belt 1.4, the arc block 1.31 moves to the preset position, and then the motor 1.6 is started, which causes each thread rolling roller 1.1 to rotate, thus realizing thread rolling.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
