Description

Technical Field

[0001] This application relates to the field of bolt processing apparatus, and more particularly to a bolt thread rolling apparatus. Background Technology

[0002] Thread rolling machines are multi-functional cold extrusion forming machine tools. Thread rolling machines can perform thread rolling, straight knitting, and oblique knitting on workpieces in a cold state within their rolling pressure range; rolling of spur gears, helical gears, and helical spline gears; straightening, diameter reduction, burnishing, and various forming rolling.

[0003] In related technologies, please refer to Chinese Utility Model Patent No. CN210848145U, which discloses a bolt thread rolling mechanism. This utility model includes two rolling wheels and a support assembly disposed between and below the two rolling wheels. The support assembly includes a mounting block, a sliding groove formed on the mounting block and extending along the axial direction of the rolling wheels, a support block disposed in the sliding groove, and a rotating roller rotatably connected to the support block. The axis of the rotating roller is parallel to the axis of the rolling wheels. Through the above arrangement, the friction between the workpiece and the support assembly is converted into rolling friction, thereby reducing the impact on the quality of the workpiece.

[0004] In the aforementioned technologies, the bolts need to be manually placed between two rolling rollers for thread rolling during loading. After the operation is completed, the bolts are removed. The manual loading and unloading operation is inconvenient and inefficient. Utility Model Content

[0005] To address the inconvenience and low efficiency of manual loading and unloading during thread rolling, this application provides a bolt thread rolling device.

[0006] The bolt thread rolling device provided in this application adopts the following technical solution:

[0007] A bolt thread rolling device includes a frame with a worktable on the frame. Two thread rolling wheels are arranged parallel to each other on the worktable, forming a thread rolling space between them. A first driving member is provided on the worktable to drive the thread rolling wheels to rotate. A feeding assembly is provided on one side of the frame, including a pushing cylinder and a conveyor belt. The conveyor belt is located on one side of the worktable and is used to transport bolts to the side of the thread rolling wheels. The pushing cylinder is located on the side of the conveyor belt away from the worktable, and the piston rod of the pushing cylinder is provided with a clamping member for holding the bolts. A support roller is provided on the worktable at the location of the thread rolling wheels. A second driving member is provided on the frame to move the support roller. A receiving box is provided on the frame below the worktable.

[0008] By adopting the above technical solution, when the bolt is placed on the conveyor belt and transported to the thread rolling wheel, the clamping part at one end of the pushing cylinder pushes one end of the bolt head and pushes the bolt to the thread rolling wheel. The second driving part drives the support roller to be located under the bolt. At this time, the first driving part drives the thread rolling wheel to rotate for thread rolling. After the thread rolling is completed, the clamping part separates from the bolt, the pushing cylinder returns to its original position, and the second driving part drives the support roller to move. The bolt falls from the support roller to the receiving box for collection. The bolt thread rolling loading and unloading operation is relatively convenient.

[0009] Optionally, the clamping component includes a clamping block and a screw. A support plate is rotatably mounted at one end of the piston rod of the pushing cylinder. A sliding groove is provided on the support plate. The screw is rotatably mounted at the sliding groove of the support plate. The screw has two opposite threads. The clamping block is slidably mounted at the sliding groove of the support plate. Two clamping blocks are arranged opposite each other and are threadedly connected to the screw at the two threaded sections. A first motor for driving the screw to rotate is provided on the support plate.

[0010] By adopting the above technical solution, the first motor drives the screw to rotate, which in turn moves the two opposing clamping blocks to clamp the bolt head on both sides. At this time, the pusher cylinder pushes the support plate to move the bolt to the thread rolling wheel for thread rolling, making the feeding operation more convenient.

[0011] Optionally, the first driving component includes a drive motor and a connecting rod. One end of the connecting rod is connected to the thread rolling wheel, the drive motor is mounted on the frame, and the end of the connecting rod opposite to the thread rolling wheel is connected to the output shaft of the drive motor.

[0012] By adopting the above technical solution, the drive motor drives the connecting rod to rotate, which in turn drives the thread rolling wheel to rotate, making the operation of driving the thread rolling wheel to rotate convenient and quick.

[0013] Optionally, two support rollers are provided and arranged parallel to each other. A rotating rod is provided on the frame. The support rollers are rotatably mounted at one end of the rotating rod, and the end of the rotating rod opposite to the support rollers is connected to the second driving member.

[0014] By adopting the above technical solution, the second driving component drives the rotating rod to rotate, and the rotating rod drives the support rollers on both sides to move. The bolts fall from the support rollers to the receiving box on the lower side for collection, making the unloading operation more convenient.

[0015] Optionally, the second driving component includes a support cylinder and a connecting rod. The support cylinder is mounted on the frame and located below the rotating rod. One end of the connecting rod is connected to the end of the rotating rod away from the support roller, and the end of the connecting rod away from the rotating rod is connected to one end of the piston rod of the support cylinder.

[0016] By adopting the above technical solution, the support cylinder drives the connecting rod, which in turn drives the rotating rod to rotate. The rotating rod then drives the support roller to move, making the driving operation more convenient.

[0017] Optionally, a rotating disk is provided on the frame on one side of the thread rolling wheel.

[0018] By adopting the above technical solution, one end of the bolt is pressed against the rotating disk, which limits the bolt end and makes it less likely to move or shake during thread rolling.

[0019] Optionally, the conveyor belt is provided with partitions.

[0020] By adopting the above technical solution, the bolts are placed between two adjacent partitions, which facilitates the feeding of materials by the pusher cylinder on one side.

[0021] Optionally, the clamping block is provided with an anti-slip rubber pad.

[0022] By adopting the above technical solution, the friction between the clamping block and the bolt head is enhanced, reducing the probability of the bolt head wobbling during thread rolling.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the bolt is placed on the conveyor belt and transported to the thread rolling wheel, the clamping part at one end of the pusher cylinder pushes the bolt to the thread rolling wheel. At this time, the first drive unit drives the thread rolling wheel to rotate for thread rolling. After the thread rolling is completed, the clamping part separates from the bolt, the pusher cylinder returns to its original position, and the second drive unit drives the support roller to move. The bolt falls from the support roller to the receiving box for collection. The bolt thread rolling loading and unloading operation is relatively convenient.

[0025] 2. One end of the bolt is pressed against the rotating disc to limit the bolt's position, preventing it from shifting or shaking during thread rolling;

[0026] 3. Anti-slip rubber pads reduce the probability of bolt head wobbling during thread rolling. Attached Figure Description
