Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, and in particular to an adjustment component for an encoder of a steel bar thread rolling machine. Background Technology

[0002] In the field of steel bar processing, threading the ends of steel bars is a common and important process, widely used in many engineering projects such as construction, bridges, and railways. As a key piece of equipment for realizing this process, the performance and stability of the steel bar thread rolling machine directly affect the quality and efficiency of steel bar thread processing.

[0003] Traditional rebar thread rolling machines typically use manual control of the thread processing length, adjusting the thread length with limit switches or electromagnetic switches and adjusting the rib stripping length with bearing stops. The adjustment process requires wrenches to turn bolts, resulting in inaccurate adjustment positions and low adjustment efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing an encoder adjustment component for a rebar thread rolling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustment assembly for an encoder of a rebar thread rolling machine, comprising: Workbench; The main unit is mounted on the workbench; The encoder is mounted on one side of the workbench via a mounting plate; A transmission assembly, connecting the host and the input end of the encoder, is configured to convert the linear motion of the host into the rotational motion of the encoder input end; When the host moves, the encoder input end is driven to rotate through the transmission component, thereby accurately measuring the movement parameters of the host in real time and improving the accuracy and consistency of rebar thread processing.

[0006] As a further improvement to the above technical solution: It also includes support rollers, which can be adaptively arranged on both sides of the clamp for supporting the reinforcing bars; The support roller is configured to automatically adjust its support position according to the diameter of the reinforcing bar, so as to prevent the reinforcing bar from shaking or shifting during processing.

[0007] The transmission assembly includes: A rack is fixed to one side of the main unit; The gear meshes with the rack; A rotating shaft is used to fix the gear in place. A timing pulley and a timing belt connect the rotating shaft and the input end of the encoder.

[0008] Also includes: A rotating base is fixed to the top of the worktable; A swing arm is rotatably mounted on one side of the rotating seat via a pin, and the rotating shaft is rotatably mounted on the swing arm via a bearing; A limiting post is fixed to the side of the swing arm and the worktable that are close to each other; The first spring is sleeved on the two limiting posts, with its two ends respectively abutting the swing rod and the worktable; The first spring is configured to elastically support the swing rod, ensuring that the gear and the rack remain engaged.

[0009] In this invention, the encoder adjustment mechanism mounts the encoder on a mounting plate on one side of the worktable and connects the encoder input end to the host machine via a transmission assembly. The encoder input end rotates thanks to the power of the host machine's movement, enabling the encoder to record relevant data about the host machine's movement, such as distance and speed, in real time and accurately. During the threading process at the rebar end, this precise data provides a reliable basis for subsequent quality control and process optimization, helping to improve the accuracy and consistency of thread processing, reduce the defect rate caused by inaccurate processing parameters, and improve product quality. In this utility model, the rebar thread rolling machine has support rollers arranged on both sides of the clamp and are self-adjustable. These rollers can automatically adjust the support position and angle according to the different specifications and sizes of rebars, in conjunction with the clamping plate. During the rebar processing, no matter how the diameter of the rebar changes, the support rollers can always maintain effective support for the rebar, preventing the rebar from shaking or shifting during processing, ensuring the stability of the rebar during processing, thereby improving the accuracy and quality of thread processing, reducing the risk of equipment damage caused by rebar shaking, and extending the service life of the equipment. In this utility model, a rebar rolling machine is provided with a bidirectional screw in the first fixed seat of the clamp. The bidirectional screw is driven to rotate by a motor, so that the two drive seats move in opposite directions or away from each other along the bidirectional screw, thereby driving the clamping plate to clamp or loosen the rebar. At the same time, the V-shaped groove on the inner side of the clamping plate can position the rebar, which can adapt to the clamping requirements of rebars of different specifications, and improve the versatility and flexibility of the equipment.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0013] Reference Figures 1-5 This is an encoder adjustment component, mainly used in rebar processing scenarios, and is used in conjunction with a rebar thread rolling machine to achieve precise control. The rebar thread rolling machine mainly includes a worktable 1, a main unit 2, a clamp 3, a support roller 4, a positioning mechanism, and the aforementioned encoder adjustment mechanism.

[0014] The workbench 1, serving as the base of the entire mechanism, is welded from high-strength steel to ensure stability during processing. Its robust structure can withstand the forces generated by the operation of each component, preventing equipment displacement due to vibration or uneven stress, and providing a reliable working platform for the entire adjustment mechanism. The main unit 2 includes a transverse slide fixedly mounted on the right side of the worktable surface, a reducer connected to the transverse slide, and a feed mechanism disposed inside the slide; a servo motor is fixedly mounted at the input end of the reducer, and a thread rolling cutter fixture is fixedly mounted at the output shaft of the reducer, with a straight thread rolling cutter fixedly mounted inside the thread rolling cutter fixture; a positioning ring is rotatably mounted on the right side of the thread rolling cutter fixture, and a water inlet is fixedly mounted on the positioning ring, with the inner end of the water inlet leading between the thread rolling cutter fixture and the straight thread rolling cutter, which is the same as that used in patent document CN221754620 U.

[0015] The clamp 3 includes a first fixed base 31, which is made of cast iron. The cast iron first fixed base 31 has high strength and rigidity, capable of withstanding the force generated when clamping the rebar, ensuring the stability of the clamp 3. It is fixed to the top of the workbench 1 and located on one side of the main unit 2. A bidirectional screw 32 is rotatably mounted inside the first fixed base 31 via bearings. The bidirectional screw 32 is made of 45# steel with a quenched and tempered finish, has a diameter of 25mm, and a pitch of 5mm. The 45# steel bidirectional screw 32, after quenching and tempering, has high strength and toughness, meeting the requirements of frequent rotation and stress. The rotation of the bidirectional screw 32 drives two drive seats 33 to move towards or away from each other, achieving clamping and releasing of the rebar. Two drive seats 33 are slidably mounted inside the first fixed base 31, both threaded onto the bidirectional screw 32. Driven by the bidirectional screw 32, the drive seats 33 slide along the guide rail inside the first fixed base 31, converting the rotational motion of the bidirectional screw 32 into linear motion. A motor 34 is fixedly mounted on one side of the first fixed base 31. The motor 34 is a three-phase asynchronous motor of model Y2-90L-4 with a power of 1.5kW. The motor 34 provides power for the rotation of the bidirectional screw 32 and transmits the power to the bidirectional screw 32 through a coupling to drive its rotation.

[0016] On one side of the workbench 1, a mounting plate 12 is fixedly connected by M8×20 bolts. The mounting plate 12 is made of 10mm thick aluminum alloy plate, which ensures strength while reducing weight. The aluminum alloy mounting plate 12 can support the weight of the encoder 5 while reducing the overall weight, making it easier to install and move the equipment. The encoder 5 is an incremental rotary encoder of model E6B2-CWZ6C, and its input end is connected to the host 2 through a transmission assembly. The function of the encoder 5 is to convert the mechanical motion of the host 2 into electrical signals so that the control system can accurately grasp the operating status of the host, such as displacement, speed and other parameters.

[0017] The transmission assembly includes a rotating seat 8 bolted to the top of the workbench 1, and a swing rod 9 rotatably connected to the rotating seat 8 via a pin. The rotating seat 8 provides a stable pivot point for the swing rod 9, allowing it to rotate flexibly around the pin. A rotating shaft 10 is rotatably mounted on one side of the swing rod 9 via a bearing. A gear 11 is fixedly mounted on one end of the rotating shaft 10. The gear 11 has a module of 2 and 30 teeth. The meshing transmission between the gear 11 and the rack 7 converts the linear motion of the main unit 2 into the rotational motion of the gear 11, thereby driving the rotating shaft 10 to rotate. A rack 7, 200mm long and matching the module of the gear 11, is bolted to one side of the main unit 2. The rack 7 is fixedly connected to the main unit 2; when the main unit 2 moves, it drives the rack 7 to move, achieving meshing transmission with the gear 11. The other end of the rotating shaft 10 and the input end of the encoder 5 are connected by a synchronous pulley 14 and a synchronous belt 15. The synchronous pulley 14 has 20 teeth, and the synchronous belt 15 is an H-type polyurethane synchronous belt to ensure transmission accuracy. The transmission method of the synchronous pulley 14 and the synchronous belt 15 has the characteristics of smooth transmission and high precision, which can accurately transmit the rotational motion of the rotating shaft 10 to the input end of the encoder 5 and reduce transmission error.

[0018] To provide elastic support for the swing arm 9, limit posts 16 are fixed on the sides of the worktable 1 and the swing arm 9 that are close to each other. The same first spring 17 is sleeved on the two limit posts 16. The first spring 17 is made of spring steel with a wire diameter of 3mm, an outer diameter of 20mm, and an initial compression of 10mm, to ensure that the gear 11 can always mesh with the rack 7.

[0019] The control panel 6 is located on one side of the workbench 1 and features a waterproof and dustproof design. The panel includes an encoder parameter display window and adjustment buttons, allowing operators to monitor and adjust encoder parameters in real time. The waterproof and dustproof design protects the internal electronic components of the control panel 6 from external environmental influences, extending the equipment's lifespan. The encoder parameter display window clearly shows the host operating parameters acquired by the encoder, such as displacement and speed; the adjustment buttons allow operators to easily set and adjust the encoder parameters according to actual processing needs, achieving precise control over the rebar processing process.

[0020] In practical use, when the host machine 2 moves, the rack 7 drives the gear 11 to rotate, which in turn drives the input end of the encoder 5 to rotate via the rotating shaft 10, synchronous pulley 14, and synchronous belt 15. The encoder 5 converts the rotation signal into an electrical signal and feeds it back to the control system, achieving precise control of the rebar processing process. This fully meets the precision requirements of rebar processing. The high-precision transmission and encoder counting ensure that the control system accurately obtains the operating information of the host machine, thereby achieving precise control of the dimensions and quality of the rebar processing.

[0021] This application can be used in the field of steel bar processing, or in other fields applicable to this application. Example

[0022] refer to Figures 1-5 An adjustment component for the encoder of a rebar thread rolling machine, which is applied in the field of rebar processing. Both drive seats 33 are bolted together with clamping plates 35. The clamping plates 35 are made of 40Cr alloy steel with a thickness of 20mm. 40Cr alloy steel has high strength and wear resistance, ensuring that the clamping plates 35 are not easily worn during frequent clamping of reinforcing bars, thus extending their service life. The inner side of the clamping plates 35 has V-shaped grooves 36 for positioning the reinforcing bars, with an angle of 120°. The design of the V-shaped grooves 36 can accommodate reinforcing bars of different diameters. The two inclined surfaces of the V-shape, in conjunction with two support rollers 4, fix the reinforcing bars in the center position, ensuring the stability of the reinforcing bars during processing.

[0023] The support rollers 4 are self-adjusting and positioned on both sides of the clamp 3. The support rollers 4 are 50mm diameter rollers. Their function is to support the reinforcing bars during processing, preventing bending and deformation due to their own weight or processing force, thus ensuring the straightness and processing quality of the reinforcing bars. The worktable 1 also serves as a base, with two sets of support frames 18 bolted to its top. These two sets of support frames 18 are located on either side of the first fixed seat 31. The support frames 18 are welded from rectangular steel pipes, with dimensions of 100mm × 50mm × 5mm. The support frames 18 provide a stable support structure for the connecting rods, capable of withstanding various forces generated during reinforcing bar processing, ensuring stable operation of the equipment. One side of the support frame has a slotted hole. The slotted hole design allows the connecting rods to move up and down within a certain range to accommodate the support requirements of processing reinforcing bars of different diameters. Connecting rods slide within the two slotted holes on the same side. The connecting rods connect and transmit force, while the support rollers are mounted on the connecting rods via bearings, transmitting the force received by the support rollers to the second spring. Two second fixing blocks are fixedly installed on the outer side of the support frame, and a guide rod is fixed between the two second fixing blocks. The guide rod provides guidance for the sliding of the connecting rod, ensuring that the connecting rod can only move up and down along the direction of the guide rod, thus ensuring the support stability of the support roller. The connecting rod is slidably sleeved on the two guide rods, and a second spring is sleeved on the outer wall of the guide rod. The second spring is made of spring steel to ensure that the connecting rod can slide smoothly under force. When the rebar is clamped, the support roller is subjected to downward pressure. The connecting rod compresses the second spring, and the elasticity of the second spring can reset the support roller. At the same time, it automatically adjusts the support height according to the diameter of the rebar to ensure the horizontal state of the rebar during processing.

[0024] When in use, place the reinforcing bar on the two support rollers 4, with one end of the reinforcing bar located on one side of the main unit 2; The starter motor 34 drives the bidirectional screw 32 to rotate. During the rotation of the bidirectional screw 32, it can drive the two drive seats 33 to move closer to each other. The movement of the drive seats 33 can drive the clamping plate 35 to move. When the clamping plate 35 contacts the steel bar, it can use the two V-grooves 36 to position the steel bar. (When the center point of the steel bar is higher than the clamping center point, the V-grooves 36 can be used to drive the steel bar to move downward, squeeze the support roller 4, and drive the connecting rod 181 to move downward to compress the second spring 184). When the adjusting block 353 contacts the rib on the outside of the steel bar, the rib and the groove 354 can be used to squeeze the adjusting block 353 to move within the two first fixed blocks 352. When the rib is located within the groove 354, it continues to clamp and can drive the adjusting block 353 to move laterally within the two first fixed blocks 352, so that the second locking strip 357 and the first locking strip 356 engage to fix the position of the adjusting block 353 until the steel bar is clamped and fixed. The motor 34 inside the start-up workbench 1 controls the movement of the main unit 2 and starts the main unit 2 to control the rotation of the cutter head. While rotating, the main unit 2 moves to achieve the feeding action. During the movement of the main unit 2, it can drive the rack 7 to move. The movement of the rack 7 can drive the gear 11 to rotate. The rotation of the gear 11 can drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 can drive the encoder 5 to rotate through the synchronous pulley 14 and the synchronous belt 15, and then feed back to the internal controller. When it moves to a certain distance, it controls the main unit 2 to move in the opposite direction and exit, and the processing is completed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
