Description

[Technical field]

[0001] The utility model relates to the technical field of bolt production, in particular to the technical field of a bolt thread rolling device. [Background technology]

[0002] Bolts are a commonly used fastener that can connect two or more parts together to form a complete system or machine. For example, in the fields of construction and machinery, bolts are often used to connect bridges, building structures, vehicles and machines. The main function of bolts is fastening. They can firmly fix two parts together by rotating the nut to ensure the stability and safety of the system or machine. In the production and processing of bolts, thread processing is particularly important, and is generally operated by a thread rolling machine. The thread rolling machine is a multifunctional cold extrusion forming machine tool. The thread rolling machine can perform thread, straight grain, and twill rolling on the workpiece in a cold state within its rolling force range. At present, during the processing, workers stand next to the thread rolling machine and hold the bolt with both hands to roll the thread. The overall process is more time-consuming and laborious through manual operation. Because the worker holds the bolt with both hands to roll the thread, the bolt is easily affected by slight shaking, visual accuracy and other human factors during thread rolling, and the accuracy of the bolt rolling cannot be ensured. Deflection can easily lead to poor processing results.

[0003] In order to solve the problems raised in the background technology, publication number CN212884762U discloses a bolt thread rolling device, which makes the bolt more stable by providing a second sliding block, a second bolt groove, a second fastening bolt and a sliding rod, thereby avoiding the problems of low thread rolling accuracy and high scrap rate due to manual thread rolling by holding the bolt. Not only can the bolt be stably fixed by the device, but also the manual rotation is avoided by providing a rotating handle, thereby making the overall operation more efficient and the production of the product more efficient. However, the structure still has the following shortcomings:

[0004] 1. Although this structure improves the stability of the bolts during processing, it lacks a clamping structure, which requires workers to put in and take out the bolts before and after processing, thereby increasing the risk.

[0005] 2. The structure lacks a movable structure, so the thread rolling wheel cannot be moved, resulting in the inability to roll bolts of different specifications. [Contents of the utility model]

[0006] The purpose of the utility model is to solve the problems in the prior art and to provide a bolt thread rolling device which can be put in and taken out with a clamping structure before and after processing, thereby improving safety performance, and the thread rolling wheel can be moved to process bolts of different specifications.

[0007] To achieve the above-mentioned purpose, the utility model proposes a bolt thread rolling device, including a workbench, support columns, a thread rolling structure, a slide groove, a movable structure, and a clamping structure. A plurality of support columns are vertically arranged at the lower end of the workbench, and a thread rolling structure for bolt thread rolling is symmetrically arranged at the upper end of the workbench. A slide groove is opened at the upper end of the workbench, and a movable structure is arranged inside the workbench and at the lower end of the slide groove. The movable structure is used to drive the thread rolling structure to move, and a clamping structure matching the thread rolling structure is arranged on the upper side of the workbench.

[0008] Preferably, the thread rolling structure includes a support plate, a thread rolling wheel, a thread rolling shaft, and a first drive motor. The support plate is in a concave shape. A thread rolling wheel is rotatably provided on the upper end of the support plate. A thread rolling shaft is rotatably provided inside the thread rolling wheel. Both ends of the thread rolling shaft extend to both sides of the thread rolling wheel and pass through the support plate respectively. A first drive motor is provided on one side of the support plate, and the output end of the first drive motor passes through the support plate and is connected to the thread rolling shaft.

[0009] Preferably, the width of the thread rolling wheel is greater than the width of the support plate.

[0010] Preferably, the movable structure includes a rotating rod, a sliding block, a connecting rod, and a second drive motor. The rotating rod is located inside the workbench and flush with the slide groove. A plurality of sliding blocks are arranged outside the rotating rod. A connecting rod is connected to the top of the sliding block. The sliding block is connected to the bottom of the support plate through the connecting rod. A second drive motor is arranged on one side of the outside of the workbench. The output end of the second drive motor passes through the workbench and is connected to the rotating rod.

[0011] Preferably, the clamping structure includes a base, a support seat, an electric telescopic rod, and a clamping claw. A support seat is arranged above the base, an electric telescopic rod is arranged on one side of the support seat, and a clamping claw for clamping a bolt is connected to the end of the electric telescopic rod.

[0012] Preferably, a control panel is provided on the front surface of the workbench, and the first drive motor, the second drive motor and the electric telescopic rod are all electrically connected to the control panel.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model can improve the processing efficiency and increase the safety performance by coordinating the use of the clamping structure and the thread rolling structure. After the bolt to be processed is placed on the clamping jaws, the thread rolling shaft is driven to rotate by the first driving motor, and the thread rolling shaft drives the thread rolling wheel to rotate. Then the movement of the electric telescopic rod is started through the control panel to extend the electric telescopic rod forward until the bolt to be processed is placed between the two thread rolling wheels. Then the electric telescopic rod retracts backward. When the bolt processing is completed, the electric telescopic rod continues to extend forward, and the processed bolt is clamped by the clamping jaws, thereby avoiding close contact between the staff's hands and the thread rolling wheel, reducing the risk of injury, increasing safety performance, and solving the problem that the bolts need to be put in and taken out by the staff before and after processing, which is prone to injury.

[0015] 2. The utility model can perform thread rolling on bolts of different specifications by setting a movable structure. The second drive motor is started through the control panel. The second drive motor drives the rotating rod to rotate. The rotation of the rotating rod drives the two sliding blocks to move closer to or away from each other. The movement of the sliding blocks drives the thread rolling structure to move, so that bolts of different specifications can be thread rolled, which solves the problem that the thread rolling wheel cannot move, resulting in the inability to process bolts of different specifications.

[0016] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
