Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, specifically to a portable wire tension measuring instrument. Background Technology

[0002] In today's technological context, the shortcomings of wire tension measurement technology mainly lie in the limitations of mainstream solutions, which fail to meet the core requirements of real-time tension control, high precision, low cost, and closed-loop regulation in wire laying scenarios. Portable tension meters, commonly used in routine production and maintenance, are unsuitable for scenarios requiring strict tension control during wire laying. They cannot capture dynamic tension fluctuations caused by uneven wire thickness and speed variations during laying, making it difficult to accurately measure the micro-tension required for medical stent production. They are also susceptible to surface contamination, burrs, and human operator experience, leading to significant measurement errors. While online tension sensors used in automated control systems can achieve real-time measurement, they are prohibitively expensive, significantly increasing the financial burden on companies. Furthermore, their actual accuracy still falls short of standards, and they are easily affected by mechanical vibrations from the laying equipment and ambient temperature, making it difficult to achieve high precision. Overall, these technologies cannot adequately meet the cross-scenario measurement needs, ranging from the micro-tension of medical stents to the tens of kilograms of tension in power cables.

[0003] Therefore, how to provide a portable wire tension measuring instrument to overcome the shortcomings of existing measuring devices is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Therefore, this utility model provides a portable wire tension measuring instrument to solve the problem of inaccurate measurement results caused by low measurement accuracy and small measurement range in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses a portable wire tension measuring instrument, comprising: The outer shell has a hollow internal structure, in which a pressure sensor is installed, and guide wheels are installed on the side walls of the outer shell; A tension wheel is mounted on the side wall of the housing, the tension wheel is positioned above the guide wheel, and a vibration damping wheel is positioned above the tension wheel; A transmission wheel is mounted on the side wall of the housing, the transmission wheel is located above the vibration damping wheel, and a mounting wheel is provided above the transmission wheel; A swing arm, one end of which is inserted into the mounting wheel, and a limit post is provided above the mounting wheel, the limit post being installed on the side wall of the outer casing; An adjustment assembly is mounted on the side wall of the housing, and a portion of the adjustment assembly is connected to the rocker arm; Lead plate, mounted on the bottom of the housing; The screen is mounted on the outside of one of the side walls of the housing.

[0006] In one possible implementation, the tension wheel includes: A tension wheel shaft is inserted into the side wall of the outer casing and connected to the internal pressure sensor.

[0007] In one possible implementation, the damping wheel includes: A vibration damping wheel shaft is mounted on the side wall of the housing at one end. A vibration damping roller is rotatably connected to the vibration damping wheel shaft. Annular baffles are installed on the outer surfaces of both ends of the vibration damping roller. A vibration damping wheel groove is formed between the outer side of the vibration damping roller and the two annular baffles.

[0008] In one possible implementation, the mounting wheel has a groove and a mounting hole in the middle, the groove and the mounting hole are connected, and a fixing hole is provided on the outer wall of the mounting wheel.

[0009] In one possible implementation, the pendulum includes: A handle is inserted into the mounting wheel, and a connecting ring is mounted on the handle, the connecting rings being arranged in pairs; One end of the rod is inserted into the handle, and the other end of the rod is connected to a swing pulley.

It can accurately capture the minute tension required for medical stent production, and also stably measure the tens of kilograms of tension in power cable laying scenarios. There is no need to configure different equipment for different scenarios; only some components need to be replaced. Moreover, the telescopic pressure block can measure tension more accurately, further reducing errors. Attached Figure Description

[0016] Please refer to Figures 1-6 The present invention discloses a portable wire tension measuring instrument, such as... Figure 1 The device includes a housing 1, a lead plate 2, a guide wheel 3, a tension wheel 4, a damping wheel 5, a transmission wheel 6, a mounting wheel 7, a limiting post 8, an adjustment assembly 9, a swing arm 10, and a screen 11. The housing 1 has a hollow structure inside, in which a pressure sensor is installed. The guide wheel 3 is installed on the side wall of the housing 1. The tension wheel 4 is installed on the side wall of the housing 1 and is positioned above the guide wheel 3. The damping wheel 5 is positioned above the tension wheel 4. The transmission wheel 6 is installed on the side wall of the housing 1 and is positioned above the damping wheel 5. The mounting wheel 7 is positioned above the transmission wheel 6. One end of the swing arm 10 is inserted into the mounting wheel 7. The limiting post 8 is positioned above the mounting wheel 7 and is installed on the side wall of the housing 1. The adjustment assembly 9 is installed on the side wall of the housing 1, and a part of the adjustment assembly 9 is connected to the swing arm 10. The lead plate 2 is installed at the bottom of the housing 1, and the screen 11 is installed on the outer side of one of the side walls of the housing 1. The limiting post 8 is used to limit the swing arm 10, the mounting wheel 7 is used to mount the swing arm 10, and the mounting wheel 7 will rotate when the swing arm 10 moves. The pressure sensor is a strain gauge pressure sensor.

[0017] In use, first identify the wire to be tested, then adjust the length of the swing arm 10, and turn the adjusting bolt 93 on the adjusting assembly 9 to adjust the tension measurement range. Select a tension wheel 4 with a suitable measurement range, then align the wire with the lead plate 2 and pass it through the guide wheel 3, then through the tension wheel 4, the damping wheel 5 and the transmission wheel 6 in sequence, and finally through the swing arm 10. Then pull the wire. When the wire passes through the tension wheel 4, the resultant force generated by the tension in the tangential direction on both sides of the contact point between the wire and the tension wheel 4 is converted into a pressure in a fixed direction on the tension wheel 4. At this time, the tension wheel shaft 41 will transmit this fixed pressure to the pressure sensor, and then the pressure will be converted into a weak signal by the pressure sensor. The weak signal is then amplified by the hardware circuit. When the tension wheel 42 rotates, the telescopic pressure block 44 is compressed after contacting the wire. The pressure sensor measures the tension generated by the wire on the tension wheel 42. In addition, the elastic force generated by the compressed spring 45 inside the telescopic pressure block 44 is added. The force on the tension wheel shaft 41 at this time is defined as the peak tension. The pressure measured when the wire passes through the tension wheel groove 43 is defined as the normal tension. Several telescopic pressure blocks 44 are arranged in a regular pattern. The measured peak tension and normal tension appear regularly. The pressure sensor sends a regular wave signal to the detection component. If the wire slips during measurement, the appearance of the peak tension and normal tension will be abnormal. For example, if the peak tension or normal tension is displayed for a long time or irregularly, the wave signal regularity will be disrupted, causing the detection component to issue an alarm, which further reduces the error generated during measurement. The measured tension is displayed on the screen 11. The tension wheel 4 is equipped with a telescopic pressure block 44. During measurement, the wire will vibrate due to the protrusion. Therefore, when the wire passes through the damping wheel 5, the damping block 53 in the middle of the damping wheel 5 is used to absorb the energy generated by the vibration, thereby playing a role in damping. The wire is connected to the swing rod pulley 104 through the transmission wheel 6. When the wire is pulled, the swing rod 10 will swing with the wire. The connected spring 94 buffers the wire to prevent inaccurate measurement data caused by the wire shaking when it exits the measurement.

[0018] In a specific embodiment, such as Figures 2-3 The tension wheel 4 includes a tension wheel shaft 41, a tension wheel body 42, a tension wheel groove 43, telescopic pressure blocks 44, and a pressure spring 45. One end of the tension wheel shaft 41 is inserted into the side wall of the outer casing 1 and connected to the internal pressure sensor. The tension wheel body 42 is rotatably connected to the tension wheel shaft 41. The tension wheel body 42 has a tension wheel groove 43 on its outer circumference. Several telescopic pressure blocks 44 are drivenly connected to the tension wheel groove 43, and a pressure spring 45 is installed inside the telescopic pressure blocks 44. The tension wheel shaft 41 converts the received wire tension into pressure and transmits it to the pressure sensor. The tension wheel groove 43 is used to transmit the normal tension, and the telescopic pressure blocks 44 are used to transmit the peak tension.

Annular baffles 52 are installed on the outer surfaces of both ends of the vibration damping roller 53, and a vibration damping wheel groove 54 is formed between the outer side of the vibration damping roller 53 and the two annular baffles 52. The vibration damping roller 53 is made of rubber, which can better absorb the energy brought by vibration, making the measurement process more stable.

[0020] In a specific embodiment, such as Figure 5 The mounting wheel 7 has a groove 71 and a mounting hole 72 in the middle, and the groove 71 and the mounting hole 72 are connected. The outer wall of the mounting wheel 7 has a fixing hole 73. The mounting hole 72 is used to install the rocker arm 10, and the fixing hole 73 can be used to fix the rocker arm 10 with a mounting screw.

[0021] In a specific embodiment, such as Figure 6 The pendulum 10 includes a handle 101, a connecting ring 102, a rod body 103, and a pendulum pulley 104. One end of the handle 101 is inserted into the mounting wheel 7, and the connecting ring 102 is mounted on the handle 101. The connecting rings 102 are arranged in pairs. One end of the rod body 103 is inserted into the handle 101, and the other end of the rod body 103 is connected to the pendulum pulley 104. The connecting ring 102 is used to connect the adjustment assembly 9. During measurement, the tension measurement range can be adjusted by selecting the connecting ring 102 to be connected to adjust the lever arm of the pendulum 10.

[0022] In a specific embodiment, such as Figure 7 The adjusting assembly 9 includes a mounting plate 91, an adjusting nut 92, an adjusting bolt 93, and a spring 94. The mounting plate 91 is mounted on the side of the housing 1, and the adjusting nut 92 is mounted on the mounting plate 91. The adjusting bolt 93 is installed in the adjusting nut 92, and the end of the adjusting bolt 93 is connected to the spring 94. One end of the spring 94 is connected to the rocker arm 10. When the adjusting bolt 93 is turned, the spring 94 is stretched or contracted, increasing or decreasing the tension measurement range.

[0023] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
