Description

Technical Field

[0001] This utility model relates to the field of wire diameter measurement technology, and in particular to a wire diameter measurement structure. Background Technology

[0002] The wire diameter measuring structure, as an application of diameter measurement structures in the wire manufacturing and testing process, is used to determine the diameter of wires. During the wire production process, the accuracy of the wire diameter affects the electrical performance, mechanical performance, and service life of the wire. The wire diameter measuring structure can monitor the diameter of wires on the production line in real time, ensuring that they meet the corresponding production standards, providing strong assurance for the quality of wire products, and enabling the wires to operate stably and reliably in power transmission and signal transmission applications.

[0003] A search revealed Chinese Patent Publication No. CN213543513U, which discloses a measuring device for wires and cables. The device includes a worktable, a diameter measuring structure, and a length measuring structure. The worktable has a U-shaped frame on its upper right side. A vertically oriented strip-shaped groove on the left side of the worktable's upper surface has mounting plates symmetrically positioned at both ends. Limiting groove rollers are rotatably connected to the mounting groove on the left side and the strip-shaped groove in the middle of the worktable's upper surface via bearings. A uniformly distributed conveyor shaft is rotatably connected to the right side of the strip-shaped groove in the middle of the worktable's upper surface via a bearing. The diameter measuring structure is located inside the mounting plate. The device has a diameter measuring structure corresponding to the conveying shaft, and a length measuring structure located in the middle of the top surface of the inner wall of the U-shaped frame. This wire and cable measuring device accurately identifies wires and cables with unqualified diameters, precisely measures the length of the conveyed wires and cables, and marks unqualified wires and cables. However, during the wire conveying process, the wear of the conveying rollers causes the wire to shake during conveying, and the flexibility of the wire itself also causes it to bend and deform during conveying, making it impossible to always stay in the center position of the measuring mechanism. This leads to errors in the measurement results and cannot accurately reflect the true diameter of the wire. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a wire diameter measuring structure, which aims to improve the problem that the wire cannot always be kept in the center position of the measuring mechanism during the transmission process of the existing technology.

[0005] In summary, the present invention adopts the following technical solution: a wire diameter measuring structure, including a frame, a support frame fixedly connected to the top of the frame, a measuring component fixedly connected to the top of the support frame, wire grooves opened on the left and right sides of the measuring component, a centering guide mechanism provided on the top of the frame, conveying mechanisms provided on both the left and right sides of the top of the frame, a driving mechanism provided on the front side of the centering guide mechanism, the driving mechanism being used to drive the centering guide mechanism to run, a measuring mechanism provided inside the centering guide mechanism, the measuring mechanism being used to detect the wire, and an adjustment mechanism provided on the left side of the centering guide mechanism;

[0006] The centering guide mechanism includes a connecting block. The right side of the connecting block is fixedly connected to the bottom left side of the measuring component. Slider blocks are slidably connected to the front and rear sides of the inner wall of the connecting block. Positioning U-shaped blocks are fixedly connected to the top of the two slider blocks. Rotating shafts are rotatably connected to the inner walls of the two positioning U-shaped blocks. Conical guide rollers are rotatably connected to the upper and lower sides of the outer walls of the two rotating shafts. Rotating rings are rotatably connected to the middle of the outer walls of the two rotating shafts.

[0007] Through the above technical solution: when the centering guide mechanism is running, the measuring component is in a fixed position. When the wire approaches, the slider slides in the connecting block. Because the slider is connected to the positioning U-shaped block, it drives the positioning U-shaped block to move. The rotating shaft changes position with the positioning U-shaped block, causing the position of the tapered guide roller to change, guiding wires of different diameters. The rotating ring assists the rotating shaft to rotate, ensuring a smooth guiding process and guiding the wire to the center of the measuring mechanism.

[0008] As a further description of the above technical solution:

[0009] The adjustment mechanism includes a mounting plate, the bottom of which is fixedly connected to the top left rear end of the frame. Two rotating shafts are rotatably connected to the top left and right sides of the mounting plate. Transmission gears are fixedly connected to the rear ends of both rotating shafts and mesh with each other. A servo motor is fixedly connected to the rear side of the mounting plate. A drive gear is fixedly connected to the output end of the servo motor and meshes with the right-side transmission gear. Connecting rods are fixedly connected to the front ends of both rotating shafts. Adjustment shafts are rotatably connected to the bottom front side of each connecting rod. A guide assembly is provided on the right side of the adjustment mechanism.

[0010] Through the above technical solution: servo motor 1 is fixed to the rear side of the mounting plate and starts. Its output end drives the drive gear to rotate. The drive gear meshes with the right transmission gear, causing the right transmission gear to rotate. Because the two transmission gears are meshed, the left transmission gear also rotates, driving the two rotating shafts 2 to rotate synchronously. The connecting rod connected to the front end of the rotating shaft 2 swings accordingly, causing the adjustment shaft to change position, thereby realizing the adjustment of the wire tension. The guide component assists in guiding the wire and ensures the stability of the adjustment process.

[0011] As a further description of the above technical solution:

[0012] The measuring mechanism includes a first support roller, which is fixedly connected to the left end of the bottom inner wall of the wire passage groove. A second support roller is fixedly connected to the right end of the bottom inner wall of the wire passage groove. A transmitting device is fixedly connected to the rear inner wall of the wire passage groove. A receiving device is fixedly connected to the front inner wall of the wire passage groove. A display screen is fixedly connected to the front of the measuring component.

[0013] The above technical solution involves the following steps: the wire is fed into the wire trough by a conveying device; the first and second support rollers are at the bottom of the wire trough to keep the wire horizontal; the transmitting device sends a signal to the receiving device; the signal passes through the wire; the receiving device calculates the wire diameter based on the signal change; the measurement data is transmitted to the display screen for the operator to read the measurement results intuitively.

[0014] As a further description of the above technical solution:

[0015] The conveying mechanism includes two fixed frames 2, the bottoms of which are fixedly connected to the front and rear ends of the top left side of the frame, respectively. Conveying rollers are rotatably connected to the inner walls of both fixed frames 2. Fixed frames 3 are fixedly connected to the front and rear ends of the top right side of the frame, and output rollers are rotatably connected to the inner walls of both fixed frames 3.

[0016] Through the above technical solution: the two fixed frames on the left are firmly installed on the top left side of the frame, and the conveying rollers on them rotate under the drive of the motor. By means of the friction with the wire, the wire moves to the right. The fixed frame on the right side of the frame is also stable, and the output rollers on its inner wall continue to receive and convey the measured and the wires to be further processed, ensuring that the wires pass through the measurement area smoothly and orderly.

[0017] As a further description of the above technical solution:

[0018] The driving mechanism includes a mounting base, the rear side of which is fixedly connected to the front side of the connecting block. A second servo motor is fixedly connected to the top of the mounting base. A bidirectional lead screw is fixedly connected to the output end of the second servo motor. The front and rear sides of the outer wall of the bidirectional lead screw are respectively threaded to the inner wall of the corresponding slider.

[0019] Through the above technical solution: Servo motor 2 is fixed on the top of the mounting base, and the mounting base is connected to the front side of the connecting block. When servo motor 2 is started, the output end drives the bidirectional lead screw to rotate. Because the bidirectional lead screw is threadedly connected to the inner wall of the slider, when the lead screw rotates, the front and rear sliders slide synchronously inward and outward along the inner wall of the connecting block according to the direction of rotation, thereby accurately adjusting the position of the relevant components of the centering guide mechanism and adapting to different wires.

[0020] As a further description of the above technical solution:

[0021] The guide assembly includes two fixed frames, the bottoms of which are fixedly connected to the front and rear sides of the top of the frame, respectively. The inner walls of the two fixed frames are rotatably connected to guide shafts, and the outer walls of the guide shafts are fixedly connected to V-shaped guide rollers.

[0022] The above technical solution involves two fixed frames that are firmly connected to the front and rear sides of the top of the frame to provide support for the guide shaft. The guide shaft can rotate on the inner wall of the fixed frame, and the V-shaped guide rollers on it rotate accordingly. When the wire passes through, the V-shaped guide rollers use their special shape to limit and guide the wire from both sides, ensuring that the wire is stably transported along the predetermined path.

[0023] As a further description of the above technical solution:

[0024] The left and right sides of the two sliders are respectively slidably connected to corresponding guide rods, and the front and rear ends of the two sliders are respectively fixedly connected to the front and rear sides of the inner wall of the connecting block.

[0025] Through the above technical solution: the slider slides back and forth on the inner wall of the connecting block, the guide rod is connected to the left and right sides of the slider to guide the slider to move left and right and ensure its smooth linear motion, the front and rear ends of the slider are fixed to the inner wall of the connecting block to ensure structural stability and allow the slider to slide inside the connecting block.

[0026] As a further description of the above technical solution:

[0027] Limit blocks are fixedly connected to the front and rear ends of the two adjusting shafts, and the two transmission gears rotate in opposite directions.

[0028] The above technical solution involves a servo motor driving a transmission gear to rotate in the opposite direction, which in turn drives the adjustment shaft. A limit block is fixed at the front and rear ends of the adjustment shaft to limit its range of movement and prevent over-adjustment. The two transmission gears rotate in opposite directions, enabling the adjustment shaft to work together to accurately adjust the wire status and ensure stable system operation.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the roller of the left conveying mechanism drives the wire to the right and near the central guide mechanism. The drive mechanism works according to the thickness of the wire. The control system adjusts the servo motor to change the rotation of the bidirectional lead screw, which drives the slider and the positioning U-shaped block to adjust the spacing of the tapered guide rollers. This centrally guides wires of different diameters. The wire smoothly enters the measuring mechanism and is kept horizontal by the support roller. The diameter is measured and displayed by the sending and receiving device. The right conveying mechanism delivers the wire, thus realizing the measurement of wires of different diameters.

[0031] 2. In this utility model, the adjustment mechanism starts the servo motor, which drives the drive gear, and through the transmission gear, the rotating shaft rotates, causing the connecting rod to swing, changing the position of the adjustment shaft, applying force to the wire to adjust the tension. The V-shaped guide roller of the guide component assists in the adjustment, guides the direction of the wire, ensures the stability of the wire during adjustment, makes the tension adjustment more uniform and accurate, solves the problem of wire tension control, and ensures accurate measurement.

[0042] The centering guide mechanism 2 includes a connecting block 201. The right side of the connecting block 201 is fixedly connected to the bottom left side of the measuring component 5, serving to connect the measuring component 5 with other components. Slider blocks 202 are slidably connected to the front and rear sides of the inner wall of the connecting block 201. The sliders 202 can slide within the connecting block 201 to adjust the position of the relevant components. Positioning U-shaped blocks 203 are fixedly connected to the top of the two sliders 202. The positioning U-shaped blocks 203 are used to install and position the relevant rollers. Rotating shafts 204 are rotatably connected to the inner walls of the two positioning U-shaped blocks 203. The rotating shafts 204 enable the conical guide rollers 205 to rotate. Conical guide rollers 205 are rotatably connected to the upper and lower sides of the outer walls of the two rotating shafts 204. The conical guide rollers 205 guide and center the wire. Rotating rings 206 are rotatably connected to the middle of the outer walls of the two rotating shafts 204. The rotating rings 206 can assist the rotation of the rotating shafts 204.

[0043] The conveying mechanism 7 includes two fixed frames 701. The bottom of the two fixed frames 701 is fixedly connected to the front and rear ends of the top left side of the frame 1, respectively, to provide installation positions for the conveying rollers 702. The inner walls of the two fixed frames 701 are rotatably connected to the conveying rollers 702, which drive the wires to move. The front and rear ends of the top right side of the frame 1 are fixedly connected to fixed frames 703, which provide installation support for the output rollers 704. The inner walls of the two fixed frames 703 are rotatably connected to the output rollers 704, which deliver the measured wires.

[0044] The drive mechanism 8 includes a mounting base 801, the rear side of which is fixedly connected to the front side of the connecting block 201 for mounting a second servo motor 802. The top of the mounting base 801 is fixedly connected to the second servo motor 802, which provides rotational power to the bidirectional lead screw 803. The output end of the second servo motor 802 is fixedly connected to the bidirectional lead screw 803. The bidirectional lead screw 803 drives the slider 202 to move by rotation. The front and rear sides of the outer wall of the bidirectional lead screw 803 are respectively threaded to the inner wall of the corresponding slider 202 to achieve precise movement of the slider 202.

[0045] Specifically, the centering guide mechanism 2 can automatically adjust the guide spacing according to the wire diameter, effectively avoiding measurement errors caused by wire offset and improving measurement accuracy. The design of the conveying mechanism 7, including the second fixed frame 701, the conveying roller 702, the third fixed frame 703, and the output roller 704, realizes the smooth conveying of the wire, making the measurement process continuous and efficient. The drive mechanism 8 provides power to the centering guide mechanism 2 through the coordinated work of the mounting base 801, the second servo motor 802, and the bidirectional lead screw 803, and accurately controls the movement of the guide components, further improving the automation and stability of the measurement structure, and effectively solving the problems of low wire measurement accuracy and poor stability in the existing technology.

[0046] Reference Figure 1 , Figure 2 and Figure 4 The centering guide mechanism 2 is equipped with a measuring mechanism 6, which is used to detect the wire and obtain the wire diameter data. The measuring mechanism 6 includes a first support roller 601, which is fixedly connected to the left end of the bottom inner wall of the wire passage 11 to support the wire and keep it horizontal. A second support roller 602 is fixedly connected to the right end of the bottom inner wall of the wire passage 11, which together with the first support roller 601 supports the wire. A transmitting device 603 is fixedly connected to the rear inner wall of the wire passage 11 to transmit a measurement signal. A receiving device 604 is fixedly connected to the front inner wall of the wire passage 11 to receive the signal transmitted by the transmitting device 603 to measure the wire diameter. A display screen 605 is fixedly connected to the front of the measuring component 5 to display the measurement result.

[0047] Specifically, the first support roller 601 and the second support roller 602 in the measuring mechanism 6 are kept horizontal and at the same height, further ensuring that the wire passes through the measuring area in a horizontal state. In conjunction with the transmitting device 603 and the receiving device 604, the diameter of the wire can be accurately measured, and the measurement result can be presented intuitively on the display screen 605 for easy reading by the operator. This realizes the measurement of the wire diameter and avoids measurement errors caused by wire tilting.

[0048] Reference Figure 1 , Figure 2 and Figure 3 The adjustment mechanism 3 includes a mounting plate 301, which supports and mounts other components. Its bottom is fixedly connected to the top left rear end of the frame 1, providing a stable mounting base for the adjustment mechanism 3. Rotary shafts 302 are rotatably connected to the top left and right sides of the mounting plate 301. These shafts 302 enable the rotation of transmission gears 303 and connecting rods 306. Transmission gears 303 are fixedly connected to the rear ends of both shafts 302. The transmission gears 303 transmit power through mutual meshing, allowing for effective power transmission between the two shafts 302. A servo motor is fixedly connected to the rear side of the mounting plate 301. Servo motor 304 provides power to the entire adjustment mechanism 3. The output end of servo motor 304 is fixedly connected to drive gear 305. Drive gear 305 transmits the power of servo motor 304 to right transmission gear 303. Drive gear 305 meshes with right transmission gear 303, thereby driving right transmission gear 303 to rotate. The front ends of the two rotating shafts 302 are fixedly connected to connecting rods 306. Connecting rods 306 convert the rotation of rotating shafts 302 into the swing of adjustment shaft 307. The bottom front side of connecting rod 306 is rotatably connected to adjustment shaft 307. Adjustment shaft 307 adjusts the tension of the wire by swinging.

[0049] A guide assembly 308 is provided on the right side of the adjusting mechanism 3. The guide assembly 308 guides and stabilizes the wire. The guide assembly 308 includes two fixing brackets 3081, which provide mounting positions for the guide shaft 3082. The bottoms of the two fixing brackets 3081 are fixedly connected to the front and rear sides of the top of the frame 1, respectively, to ensure that the guide assembly 308 is firmly installed. The guide shaft 3082 is rotatably connected to the inner wall of each of the two fixing brackets 3081. The guide shaft 3082 enables the V-shaped guide roller 3083 to rotate. The V-shaped guide roller 3083 is fixedly connected to the outer wall of the guide shaft 3082. The V-shaped guide roller 3083 guides the movement direction of the wire and assists in adjusting the wire tension.

[0050] Specifically, the mounting plate 301 is securely installed on the frame 1, providing solid support for all components. The servo motor 304 drives the drive gear 305, which in turn drives the rotating shaft 302 to rotate via the transmission gear 303, causing the connecting rod 306 to swing. This, in turn, effectively adjusts the wire tension through the adjusting shaft 307, ensuring that the wire maintains appropriate tension during transport and measurement, and avoiding the impact of improper tension on measurement accuracy. The V-shaped guide roller 3083 of the guide assembly 308 is installed on the guide shaft 3082 and supported by the fixing frame 3081. It can guide the direction of the wire, further improving the stability of wire transport and ensuring the smooth progress of measurement work and the accuracy of measurement results.

[0051] Reference Figure 1 , Figure 3 and Figure 5 The left and right sides of the two sliders 202 are respectively slidably connected to corresponding + to limit the range of movement of the adjustment shaft 307 in the front and back directions, so as to prevent the adjustment shaft 307 from moving too much and damaging the wire. The two transmission gears 303 rotate in opposite directions. Through this reverse rotation, the two rotating shafts 302 can rotate in opposite directions, thereby driving the connecting rod 306 and the adjustment shaft 307 connected to them to achieve coordinated action and accurately adjust the tension of the wire.

[0052] Specifically, the guide rod 9 is slidably connected to the slider 202, which enhances the stability and accuracy of the slider 202's movement and ensures smooth centering and guiding action. The slider 202 is fixed to the connecting block 201 to ensure the overall structure is solid. The adjusting shaft 307 is equipped with a limit block 10 to prevent over-adjustment and protect the mechanism and the wire. The two transmission gears 303 rotate in opposite directions to realize the coordinated action of the adjusting shaft 307 and accurately control the tension and position of the wire.

[0053] Working principle: When the measuring structure performs measurement, the conveying rollers 702 on the two fixed frames 701 of the left conveying mechanism 7 rotate, driving the wire to the right. When wires of different diameters approach the centering guide mechanism 2, the drive mechanism 8 starts to function. The mounting base 801 is firmly connected to the front of the connecting block 201. After the servo motor 802 starts, its output end drives the bidirectional lead screw 803 to rotate. The front and rear sides of the outer wall of the bidirectional lead screw 803 are threadedly connected to the inner wall of the corresponding slider 202. When wires of different diameters are detected, the servo motor 802 can be adjusted through the pre-set control system. The control system instructs servo motor 802 to rotate a certain number of revolutions in the forward direction for thicker wires. The bidirectional lead screw 803 rotates accordingly. Due to the threaded connection between the lead screw and slider 202, the two sliders 202 slide outwards along the inner wall of the connecting block 201. The positioning U-shaped block 203 connected to the top of the slider 202 also moves outwards synchronously, increasing the distance between the tapered guide rollers 205 on the two positioning U-shaped blocks 203 to accommodate the passage of thicker wires and provide centered guidance. If a thinner wire is detected, the control system... The system commands the servo motor 802 to rotate in the opposite direction a corresponding number of revolutions, causing the bidirectional lead screw 803 to drive the slider 202 to slide inward, reducing the distance between the tapered guide rollers 205. This ensures that the thin wire can be accurately centered during the guiding process. After the wire has been precisely positioned by the centering guide mechanism 2, it smoothly enters the measuring mechanism 6. Inside the measuring mechanism 6, the first support roller 601 and the second support roller 602 at the bottom of the wire trough 11 remain horizontal and at the same height, further ensuring that the wire passes through the measuring area horizontally. At this time, the transmitting device 603 on the rear side of the inner wall of the wire trough 11 sends a specific signal. The receiving device 604 located on the front receives the signal. By analyzing and processing the signal, the diameter of the wire can be accurately measured. The measurement result is finally displayed on the display screen 605 on the front of the measuring component 5, which is convenient for the operator to read. This realizes the measurement of the wire diameter and avoids the measurement error caused by the tilt of the wire. The output roller 704 on the fixed frame 703 of the right conveying mechanism 7 rotates to send the wire that has been measured out of the measurement area. The measuring structure effectively overcomes the measurement error problem caused by the unstable wire conveying in the prior art and realizes the measurement of wires of different diameters.

[0054] Furthermore, when it is necessary to adjust the wire tension, the servo motor 304 is started and fixed to the rear of the mounting plate 301. The motor output drives the drive gear 305 to rotate, and the drive gear 305 meshes with the right transmission gear 303, causing the right transmission gear 303 to rotate. Since the two transmission gears 303 are meshed with each other, the left transmission gear 303 also rotates, thereby driving the two rotating shafts 302 to rotate synchronously. The connecting rod 306 connected to the front end of the rotating shaft 302 swings accordingly. Because the bottom front of the connecting rod 306 is rotatably connected to the adjusting shaft 307, the adjusting shaft 307 will swing along the connecting rod. Driven by 306, the position changes, and the adjusting shaft 307 contacts the wire. By changing its position, different degrees of tension are applied to the wire, thereby adjusting the tension of the wire. The V-shaped guide roller 3083 in the guide assembly 308 plays an auxiliary role. Two fixed brackets 3081 are fixed on the front and rear sides of the top of the frame 1, and the guide shaft 3082 rotates on its inner wall. The V-shaped guide roller 3083 is fixed on the outer wall of the guide shaft 3082. The V-shaped guide roller 3083 can not only guide the direction of wire movement, but also ensure the stability of the wire during the adjustment process, making the wire tension adjustment more uniform and accurate.
