Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a fully automatic high-speed thread rolling machine for bolt production. Background Technology

[0002] Thread rolling machines are specialized equipment for producing screws. There are various specifications of thread rolling machines, such as automatic thread rolling machines, flatbed thread rolling machines, semi-automatic thread rolling machines, fully automatic thread rolling machines, and high-speed thread rolling machines.

[0003] In existing thread rolling machines, operators first fix the workpiece to be processed on the thread rolling machine rod, and then manually rotate the thread rolling head on the thread rolling machine to roll the workpiece. This processing method is not only time-consuming and labor-intensive, reducing work efficiency, but also leads to unstable product quality. In traditional automatic thread rolling machines, the applied force may be uneven during the thread rolling process, affecting the processing quality of the worktable. During the operation of the bolt, there is no limit function, which may result in excessive range of motion, leading to safety hazards. In view of this, we propose a fully automatic high-speed thread rolling machine for bolt production to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic high-speed thread rolling machine for bolt production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic high-speed thread rolling machine for bolt production, comprising a base, a thread rolling mechanism, a reciprocating mechanism, a limiting baffle, a fixed frame, and a worktable. The fixed frame is fixedly connected to the upper side of the base, the thread rolling mechanism is installed on one side of the fixed frame, and a transmission frame is fixedly connected to one side of the fixed frame. The reciprocating mechanism is provided inside the transmission frame. The worktable is fixedly connected to the fixed frame below the thread rolling mechanism, and an inclined plate is provided on one side of the worktable.

[0006] Preferably, the thread rolling mechanism includes a guide frame, a thread rolling plate, guide wheels, a first top plate, a guide groove, a guide block, a striking block, a return spring, a second top plate, and a cam. The guide frame is fixedly connected to one side of the fixed frame, a guide block is provided inside the guide frame, and the thread rolling plate is movably connected to the guide groove through the guide block. The surface of the thread rolling plate is provided with a guide groove, the guide block is located in the guide groove, and multiple guide wheels are provided at equal distances on both sides of the guide plate inside the thread rolling plate.

[0007] Preferably, a first top plate is fixedly connected to the lower side of one side of the thread rolling plate, and a striking block is movably connected inside the worktable. A return spring is provided between the striking block and the worktable, and the striking block and the first top plate cooperate with each other.

[0008] Preferably, a second top plate is provided on the side of the striking block away from the first top plate, and a cam is movably connected inside the worktable. The cam and the second top plate cooperate with each other. A limit baffle is slidably connected on the worktable, and the surfaces of the limit baffle and the cam cooperate with each other.

[0009] Preferably, the reciprocating mechanism includes a transmission rod, a transmission groove, a transmission wheel, a first synchronous wheel, a synchronous belt, a second synchronous wheel, and a guide rod. A drive motor is fixedly connected to one side of the base. The output end of the drive motor is provided with a second synchronous wheel in the transmission frame. A transmission wheel is movably connected to one side of the fixed frame. A first synchronous wheel is fixedly connected to one side of the transmission wheel. A synchronous belt is sleeved between the first synchronous wheel and the second synchronous wheel.

[0010] Preferably, a transmission rod is movably connected to one side of the fixed frame, and a transmission groove is formed on the surface of the transmission rod away from the fixed frame. The thread rolling plate is located in the transmission groove. A transmission rod is movably connected to one side of the transmission wheel, and a guide rod is movably connected to the transmission wheel away from the transmission rod. The guide rod is located inside the fixed frame.

[0011] Preferably, the workbench is provided with a placement groove, in which a bolt is placed, and the bolt cooperates with the thread rolling plate and the limiting baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The drive motor starts running and outputs rotational power. The power of the motor is transmitted to the first synchronous pulley through the synchronous belt on the second synchronous pulley, thereby driving the transmission wheel to rotate reciprocally. One side of the transmission wheel pushes the transmission rod to move. As the transmission wheel rotates, the transmission rod also moves accordingly. Since there is a transmission groove on one side of the transmission rod, the thread rolling plate is confined in this groove and can perform horizontal reciprocating motion under the drive of the transmission rod. The guide rod ensures the stability of the transmission rod during movement and avoids jamming or damage caused by deviation.

[0014] 2. When the thread rolling plate moves to a certain position, the first top plate will press the striking block, causing it to move downward and apply force to the second top plate inside the worktable. The function of the return spring is to ensure that the striking block can quickly return to its position after striking. The cam is set inside the worktable and connected to the second top plate. The upper and lower positions of the limit baffle can be controlled through the cam of the second top plate, which plays a role in limiting the range of motion and ensuring safety.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figures 1-4 As shown, the present invention proposes a fully automatic high-speed thread rolling machine for bolt production, comprising a base 1, a thread rolling mechanism 2, a reciprocating mechanism 3, a limiting baffle 4, a fixed frame 8, and a worktable 9. The fixed frame 8 is fixedly connected to the upper side of the base 1, the thread rolling mechanism 2 is installed on one side of the fixed frame 8, and a transmission frame 7 is fixedly connected to one side of the fixed frame 8. The reciprocating mechanism 3 is provided inside the transmission frame 7. The worktable 9 is fixedly connected to the fixed frame 8 below the thread rolling mechanism 2, and an inclined plate 5 is provided on one side of the worktable 9.

[0022] In an optional embodiment, the thread rolling mechanism 2 includes a guide frame 201, a thread rolling plate 202, guide wheels 203, a first top plate 204, a guide groove 205, a guide block 206, a striking block 207, a return spring 208, a second top plate 209, and a cam 210. The guide frame 201 is fixedly connected to one side of the fixed frame 8. The guide block 206 is provided inside the guide frame 201, and the thread rolling plate 202 is movably connected to the guide groove 205 through the guide block 206. The guide groove 205 is opened on the surface of the thread rolling plate 202, and the guide block 206 is located in the guide groove 205. Multiple guide wheels 203 are arranged at equal distances on both sides of the guide plate inside the thread rolling plate 202.

[0023] In an optional embodiment, a first top plate 204 is fixedly connected to the lower side of one side of the thread rolling plate 202, and a striking block 207 is movably connected inside the worktable 9. A return spring 208 is provided between the striking block 207 and the worktable 9, and the striking block 207 and the first top plate 204 cooperate with each other.

[0024] In an optional embodiment, a second top plate 209 is provided on the side of the striking block 207 away from the first top plate 204, and a cam 210 is movably connected inside the worktable 9. The cam 210 and the second top plate 209 cooperate with each other. A limit baffle 4 is slidably connected on the worktable 9, and the surfaces of the limit baffle 4 and the cam 210 cooperate with each other.

[0025] When the equipment is started, the thread rolling plate 202 is in the initial position, and the striking block 207 and the return spring 208 are held together in the same state. The reciprocating mechanism 3 causes the guide groove 205 of the thread rolling plate 202 to move horizontally back and forth on the guide block 206, thereby realizing the thread rolling plate 202 rolling the threads on the surface of the bolt 6. When the thread rolling plate 202 moves to a certain position, the first top plate 204 will press the striking block 207, causing it to move downward and apply force to the second top plate 209 in the worktable 9. The function of the return spring 208 is to ensure that the striking block 207 can quickly return to its position after the striking is completed. The cam 210 is set inside the worktable 9 and connected to the second top plate 209. The cam 210 can control the up and down position of the limit baffle 4 through the second top plate 209, which plays the role of limiting the range of movement and ensuring safety.

[0026] In an optional embodiment, the reciprocating mechanism 3 includes a transmission rod 301, a transmission groove 302, a transmission wheel 303, a first synchronous wheel 304, a synchronous belt 305, a second synchronous wheel 306, and a guide rod 307. A drive motor 308 is fixedly connected to one side of the base 1. The output end of the drive motor 308 is provided with the second synchronous wheel 306 in the transmission frame 7. The transmission wheel 303 is movably connected to one side of the fixed frame 8. The first synchronous wheel 304 is fixedly connected to one side of the transmission wheel 303. A synchronous belt 305 is sleeved between the first synchronous wheel 304 and the second synchronous wheel 306.

[0027] In an optional embodiment, a transmission rod 301 is movably connected to one side of the fixed frame 8, and a transmission groove 302 is formed on the surface of the transmission rod 301 away from the fixed frame 8. The thread rolling plate 202 is located in the transmission groove 302. A transmission wheel 303 is movably connected to the transmission rod 301 on one side, and a guide rod 307 is movably connected to the transmission wheel 303 away from the transmission rod 301. The guide rod 307 is located in the fixed frame 8.

[0028] The drive motor 308 starts running and outputs rotational power. The power of the motor is transmitted to the first synchronous pulley 304 through the synchronous belt 305 on the second synchronous pulley 306, thereby driving the transmission pulley 303 to rotate reciprocally. One side of the transmission pulley 303 pushes the transmission rod 301 to move. As the transmission pulley 303 rotates, the transmission rod 301 also moves accordingly. Since a transmission groove 302 is provided on one side of the transmission rod 301, the thread rolling plate 202 is confined in this groove and can perform horizontal reciprocating motion under the drive of the transmission rod 301. The guide rod 307 ensures the stability of the transmission rod 301 during movement and avoids jamming or damage caused by deviation.

[0029] In an optional embodiment, the workbench 9 is provided with a placement slot, in which a bolt 6 is placed, and the bolt 6 cooperates with the thread rolling plate 202 and the limiting baffle 4.

[0030] The working principle of this utility model is as follows: When using this device, firstly, the drive motor 308 starts to run and outputs rotational power. The power of the motor is transmitted to the first synchronous pulley 304 through the synchronous belt 305 on the second synchronous pulley 306, thereby driving the transmission wheel 303 to rotate reciprocally. One side of the transmission wheel 303 pushes the transmission rod 301 to move. As the transmission wheel 303 rotates, the transmission rod 301 will also move accordingly. Since a transmission groove 302 is provided on one side of the transmission rod 301, the thread rolling plate 202 is confined in this groove and can perform horizontal reciprocating motion under the drive of the transmission rod 301. The setting of the guide rod 307 ensures the stability of the transmission rod 301 during movement and avoids jamming or damage caused by deviation.

[0031] When the equipment is started, the thread rolling plate 202 is in the initial position, and the striking block 207 and the return spring 208 are held together in the same state. The reciprocating mechanism 3 causes the guide groove 205 of the thread rolling plate 202 to move horizontally back and forth on the guide block 206, thereby realizing the thread rolling plate 202 rolling the threads on the surface of the bolt 6. When the thread rolling plate 202 moves to a certain position, the first top plate 204 will press the striking block 207, causing it to move downward and apply force to the second top plate 209 in the worktable 9. The function of the return spring 208 is to ensure that the striking block 207 can quickly return to its position after the striking is completed. The cam 210 is set inside the worktable 9 and connected to the second top plate 209. The cam 210 can control the up and down position of the limit baffle 4 through the second top plate 209, which plays the role of limiting the range of movement and ensuring safety.
