Description

Technical Field

[0001] This utility model belongs to the field of thread rolling wheel technology, and in particular relates to an adjustable thread rolling wheel. 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 mainly relies on several thread rolling wheels to perform thread rolling on bolts. However, the spacing between these threads is often fixed, making it only suitable for processing bolts of a single size. It is not convenient to adjust the spacing between the threads, making it difficult to meet the processing needs of bolts of different sizes. The equipment is not very versatile. Therefore, we propose an adjustable thread rolling wheel. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable thread rolling wheel. Through the adjustment mechanism and the fixing mechanism, it solves the problem that most bolts are mainly processed by several thread rolling wheels. However, the spacing of several thread rolling wheels is often fixed, which is only good for processing bolts of a single size and type. It is not convenient to adjust the spacing of the thread rolling wheels, making it difficult to meet the processing needs of bolts of different sizes and types, and the equipment has low versatility.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an adjustable thread rolling wheel, including a processing box, a controller is fixedly connected to the inner wall of the processing box, and an adjustment mechanism is provided on the outer wall of the processing box; The adjustment mechanism includes a motor frame, the outer wall of which is fixedly connected to the outer wall of the processing box. A first motor is fixedly connected to the inner wall of the motor frame. A transmission rod is fixedly connected to the bottom output end of the first motor via a coupling. A gear is fixedly connected to the outer wall of the transmission rod away from the first motor. The outer wall of the gear is rotatably connected to the inner wall of the processing box. A displacement groove is provided on the inner wall of the processing box. Several displacement blocks are slidably connected to the inner wall of the displacement groove. A rack is fixedly connected to the outer wall of each displacement block. The outer wall of the rack meshes with the outer wall of the gear. A second motor frame is fixedly connected to the outer wall of the displacement block. A second motor is fixedly connected to the outer wall of the second motor frame. A second transmission rod is fixedly connected to the bottom output end of the second motor via a coupling. A baffle is fixedly connected to the outer wall of the transmission rod away from the second motor.

[0005] Furthermore, the outer wall of the baffle is provided with a quick-release mechanism, which includes several shaped rollers and thread rolling wheels, and the outer walls of the several shaped rollers are fixedly connected to the outer wall of the baffle.

[0006] Furthermore, each of the irregularly shaped rollers has a pin seat fixedly connected to the outer wall of the end away from the baffle, and the inner wall of the pin seat has a plurality of pin grooves.

[0007] Furthermore, each of the inner walls of several of the pin slots is slidably connected to a locking block, and the outer wall of the locking block is fixedly connected to a push button.

[0008] Furthermore, a fixing rod is slidably connected to the inner wall of several of the card blocks, and the outer wall of the fixing rod is fixedly connected to the inner wall of the pin seat.

[0009] Furthermore, a spring is fixedly connected to the outer wall of the card block, and the outer wall of the spring away from the card block is fixedly connected to the inner wall of the pin seat.

[0010] Furthermore, the inner walls of several of the thread rolling wheels are provided with irregular grooves, and the inner walls of the irregular grooves are slidably connected to the outer walls of the irregular rollers.

[0011] Furthermore, the shaped roller passes through the rolling wheel to the outer wall, and the inner wall of the processing box is provided with a sliding groove, and a collection drawer is slidably connected to the inner wall of the sliding groove.

[0012] This utility model has the following beneficial effects: 1. This utility model, by incorporating a rack and pinion mechanism, allows for the adjustment of the spacing between several shaped rollers before processing to accommodate bolts of different sizes. The first motor is activated in reverse, driving a transmission rod to rotate. This transmission rod, in turn, drives a gear to rotate, which in turn moves several racks. Each rack moves a displacement block, which in turn moves a second transmission rod. This second transmission rod then moves a baffle plate, which in turn moves the shaped rollers. The shaped rollers then move the thread rolling wheels, causing them to move closer together to reduce their distance and accommodate smaller bolts. This allows for free adjustment of the spacing between the thread rolling wheels before processing to meet the needs of processing bolts of different sizes and types, significantly improving the versatility of the equipment.

[0013] 2. This utility model incorporates locking blocks. By simply squeezing several push buttons, each button will cause the locking blocks to shift, completely retracting into the pin groove and compressing the spring. During this process, the locking blocks will no longer hold the thread rolling wheel in place. Subsequently, the thread rolling wheel can be pulled away from the baffle plate, and it will detach directly from the shaped roller. This allows for quick disassembly and replacement of the thread rolling wheel when it is worn excessively due to long-term use or when different threads need to be machined on the bolt. The operation is simple while ensuring reliability.

[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

A baffle 211 is fixedly connected to the outer wall of the end of the transmission rod 210 furthest from the second motor 209. The transmission rod 210 primarily functions as a fixed limiter for the baffle 211. When the transmission rod 210 rotates, it drives the baffle 211 to rotate as well.

[0020] The outer wall of the baffle 211 is provided with a quick-release mechanism 3, which includes several shaped rollers 301 and thread rolling wheels 308. The outer walls of the shaped rollers 301 are all fixedly connected to the outer wall of the baffle 211. The baffle 211 mainly serves to fix and limit the shaped rollers 301, which can only be fixed in the position on the baffle 211. The outer wall of the end of each shaped roller 301 away from the baffle 211 is fixedly connected with a pin seat 302. The inner wall of the pin seat 302 is provided with several pin grooves 303. The inner wall of 03 is slidably connected with a locking block 304. The pin groove 303 mainly serves to limit the sliding of the locking block 304. The locking block 304 can only slide within the pin groove 303 at a fixed angle. The outer wall of the locking block 304 is fixedly connected with a push button 305. The inner walls of several locking blocks 304 are slidably connected with a fixing rod 306. The outer wall of the fixing rod 306 is fixedly connected to the inner wall of the pin seat 302.

The spring 307 can only be fixed in the position within the pin seat 302. The inner wall of the irregular groove 309 is slidably connected to the outer wall of the irregular roller 301. The irregular roller 301 passes through the thread rolling wheel 308 to the outer wall. The inner wall of the processing box 1 is provided with a sliding groove 310. A collection drawer 311 is slidably connected to the inner wall of the sliding groove 310. The sliding groove 310 mainly serves to limit the sliding of the collection drawer 311. The collection drawer 311 can slide at a fixed angle within the sliding groove 310.

[0022] One specific application of this embodiment is: When the operator needs to use the equipment, the bolt to be processed can be placed directly between several thread rolling wheels 308. Then, the controller 101 is operated to start several second motors 209. Each of the second motors 209 will drive the transmission rod 210 to rotate, which in turn drives the baffle 211 to rotate. The baffle 211 then drives the shaped roller 301 to rotate, which in turn drives the thread rolling wheels 308 to rotate. The thread rolling wheels 308 will rotate simultaneously to perform thread rolling on the bolt. Before processing... To adjust the spacing of several irregularly shaped rollers 301 for processing bolts of different sizes, the first motor 202 can be started in reverse. The first motor 202 will drive the transmission rod 203 to rotate, which in turn drives the gear 204 to rotate. The gear 204 will drive several racks 207 to move, and each rack 207 will drive the displacement block 206 to move. The displacement block 206 will drive the second transmission rod 210 to move, which in turn drives the baffle 211 to move. The baffle 211 will then drive the irregularly shaped rollers 301 to move. The displacement of roller 301 causes the shaped roller 301 to move the thread rolling wheels 308. Several thread rolling wheels 308 will move closer together to reduce their distance and accommodate smaller bolts. To replace the thread rolling wheels 308, simply engage several push buttons 305. Each push button 305 will move the locking blocks 304, which will then fully retract into the pin grooves 303 and compress the springs 307. During this process, the locking blocks 304 will no longer hold the thread rolling wheels 308, allowing the thread rolling wheels 308 to be directly replaced. Pull the thread rolling wheel 308 away from the baffle 211, and it will disengage directly from the shaped roller 301. Then, align the shaped groove 309 of the replacement thread rolling wheel 308 with the pin seat 302, and push the thread rolling wheel 308 directly. Since one side of the surface of several locking blocks 304 is relatively smooth, it will not prevent the thread rolling wheel 308 from being fitted onto the surface of the shaped roller 301. When the thread rolling wheel 308 is displaced to fit against the baffle 211, the locking blocks 304 will reset under the action of the spring 307 and cooperate to lock the thread rolling wheel 308.
