A thread rolling wheel with a clamping structure

Abstract

This utility model discloses a thread rolling wheel with a clamping structure, relating to the field of thread rolling processing technology. The utility model includes a processing table with a displacement groove on its inner wall, a support frame fixedly connected to the bottom outer wall of the processing table, and a clamping mechanism on the top outer wall of the processing table. By incorporating clamps, this utility model allows the end of the bolt to be processed to be placed between several clamps. Then, by starting the motor and rotating it clockwise, the motor drives a transmission rod to rotate, which in turn drives a gear to rotate. The gear then drives a ring rack to rotate, which in turn drives several gears (secondary gears) to rotate. Each gear (secondary gear) drives a rotating rod to rotate, which in turn drives the rack to move, and the rack to move the clamps. This achieves the effect of preemptively clamping the bolt at multiple angles before processing, preventing easy displacement of the bolt during processing.

Description

Technical Field

[0001] This utility model belongs to the field of thread rolling technology, and in particular relates to a thread rolling wheel with a clamping structure. Background Technology

[0002] Bolts are a common type of fastener that can connect two or more parts together to form a complete system or machine. In bolt manufacturing, thread processing is particularly important and is generally done using thread rolling wheels. Thread rolling wheels are the core tools for thread rolling machines. They form threads by squeezing and rubbing against the workpiece. They are widely used for thread processing of fasteners, shafts and other parts. The materials are mainly high-speed steel and cemented carbide. Their surfaces are covered with tooth patterns that match the target thread. Existing equipment can clamp bolts before processing, but the clamping surface is often small and the friction provided by clamping is very limited. This means that bolts may still easily shift due to vibration during processing, making it difficult to guarantee the quality of the finished product. Therefore, we propose a thread rolling wheel with a clamping structure. Utility Model Content

[0003] The purpose of this utility model is to provide a thread rolling wheel with a clamping structure. Through the clamping mechanism and the adjustment mechanism, it solves the problem that although the bolt can be clamped as a whole before it is processed, the clamping surface of the bolt is often small and the friction provided by the clamping is very limited. As a result, the bolt may still be easily displaced due to vibration during processing, and the quality of the finished product is difficult to guarantee.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a thread rolling wheel with a clamping structure, including a processing table, a displacement groove is provided on the inner wall of the processing table, a support frame is fixedly connected to the bottom outer wall of the processing table, and a clamping mechanism is provided on the top outer wall of the processing table. The clamping mechanism includes a fixed frame, the bottom outer wall of which is fixedly connected to the top outer wall of the processing table. A rotating ring is rotatably connected to the inner wall of the fixed frame. A limit block is fixedly connected to the outer wall of the rotating ring. A motor is fixedly connected to the inner wall of the limit block. A transmission rod is fixedly connected to the bottom output end of the motor via a coupling. A gear is fixedly connected to the outer wall of the transmission rod at the end away from the motor. A ring rack is rotatably connected to the inner wall of the rotating ring. The outer wall of the ring rack meshes with the outer wall of the gear. Several rotating rods are rotatably connected to the inner wall of the rotating ring. Gear 2 is fixedly connected to the outer wall of each of the rotating rods. The outer walls of the gear 2 mesh with the outer wall of the ring rack. Gear 3 is fixedly connected to the outer wall of each of the rotating rods at the end away from the gear 2. Several guide grooves are formed on the inner wall of the rotating ring. Clamps are slidably connected to the inner walls of the guide grooves. A rack is fixedly connected to the outer wall of each clamp. The outer walls of the racks mesh with the outer walls of the gear 3.

[0005] Furthermore, the inner wall of the displacement groove is provided with an adjustment mechanism, which includes a plurality of rotating seats, the outer walls of which are slidably connected to the inner wall of the displacement groove.

[0006] Furthermore, a second limiting block is fixedly connected to the outer wall of each of the rotating seats, and a second motor is fixedly connected to the outer wall of the second limiting block.

[0007] Furthermore, the bottom output end of the second motor is fixedly connected to a transmission rod two via a coupling, and a thread rolling wheel is fixedly connected to the outer wall of the transmission rod two.

[0008] Furthermore, the outer wall of the thread rolling wheel is rotatably connected to the inner wall of the rotating seat, and the thread rolling wheel passes through several rotating seats to the outer wall.

[0009] Furthermore, a shaft seat is fixedly connected to the bottom outer wall of each of the rotating seats, and a connecting rod is rotatably connected to the inner wall of the shaft seat.

[0010] Furthermore, a connecting block is rotatably connected to the outer wall of one end of each connecting rod away from the bearing seat, and the connecting rods pass through the connecting block to the outer wall.

[0011] Furthermore, an electric telescopic rod is fixedly connected to the inner wall of the processing table, and the bottom outer wall of the electric telescopic rod is fixedly connected to the top outer wall of the connecting shaft block.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting up clamps, simply requires placing the end of the bolt to be processed between several clamps, then starting the motor to rotate clockwise. The motor will drive the transmission rod to rotate, the transmission rod will drive the gear to rotate, the gear will drive the ring rack to rotate, the ring rack will drive several gears to rotate, and the several gears will drive the rotating rod to rotate. The rotating rod will drive the gears to rotate, the gears will drive the rack to move, and the rack will drive the clamps to move. This achieves the effect of prioritizing multi-angle clamping of the bolt before processing, preventing the bolt from easily shifting during processing, and ensuring the quality of the finished product.

[0013] 2. This utility model incorporates a bearing seat. Upon activation, an electric telescopic rod extends downwards, causing it to move downwards. This movement causes the connecting rod block to displace one end of several connecting rods, resulting in overall rotation. These connecting rods then move the bearing seat, which in turn moves the rotating seat. The rotating seat then moves the thread rolling wheels and the limiting block two, causing the thread rolling wheels to approach and engage with the front end of the bolt. Simultaneously, several second motors are activated, each driving a transmission rod two to rotate. This transmission rod two then drives the thread rolling wheels to rotate, allowing the thread rolling wheels to rotate simultaneously and perform thread rolling on the bolt. This design enables active adjustment of the thread rolling wheel position to perform thread rolling on bolts of different sizes and specifications, effectively improving the flexibility of the equipment.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
