Description

Technical Field

[0001] The utility model relates to the technical field of tension detection, and more specifically, to a tension sensor sensitivity detection device. Background Art

[0002] A force sensor is a device that converts physical signals into measurable electrical output signals. Also known as a resistance strain gauge sensor, it belongs to the category of weighing sensors. It uses two tensioning components to transmit force. While widely used in daily life, tension sensors often require continuous tension at both ends. This can lead to various wear and tear during use, resulting in inaccuracy. The slow change in the output signal when subjected to constant tension for extended periods can cause creep deformation in the tension sensor, necessitating testing. During testing, workers often apply their own tension, resulting in uneven tension on the sensor, which can easily damage it and cause damage to the bed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a tension sensor sensitivity detection device, including a fixed base plate 1, the upper end of the fixed base plate 1 is fixedly connected to a support column 2, the right side of the support column 2 is fixedly connected to a fixed component four 9, the upper end of the fixed base plate 1 is fixedly connected to a motor 3, the output end of the motor 3 is fixedly sleeved with a rotating shaft 4, the surface of the rotating shaft 4 is fixedly sleeved with a tension rope 5, the upper end of the tension rope 5 is fixedly connected to a fixed component one 6, the interior of the fixed component one 6 is sleeved with a fixed component two 7, the upper end of the fixed component two 7 is fixedly connected to a fixed component three 8, and the interior of the fixed component three 8 is sleeved with a tension sensor 10.

[0021] The tension output device consists of a motor 3, a rotating shaft 4, a tension rope 5 and a fixed component 1 6. The motor 3 can accurately control the output of tension, and continuously and stably output tension for detection. It can detect tiny tension changes, thereby providing accurate data. It has a simple structure and is easy to install and maintain. The fixed component 1 6 and the fixed component 2 7 use a standard interface, which can be easily assembled and connected. At the same time, it has a long service life and low maintenance cost.

[0022] The length of the rotating shaft 4 is greater than the horizontal distance between the motor 3 and the second fixing component 7 , and the shape of the rotating shaft 4 is cylindrical.

[0023] It is ensured that the connection point between the adjustable tension rope 5 and the rotating shaft 4 can be presented as a numerical level, and the cylindrical shape makes it easier to rotate and store the tension rope 5.

[0024] The lower end of the tension rope 5 is a rubber ring, and the inner diameter of the rubber ring is equal to the diameter of the rotating shaft 4.

[0025] The lower end of the tension rope 5 is a rubber ring. The rubber ring has objective friction and can effectively restrain the rotating shaft 4. The inner diameter of the rubber ring is equal to the diameter of the rotating shaft 4 to increase stability and ensure that the rotating shaft 4 and the tension rope 5 are not prone to slipping.

[0026] Among them, the fixing component 1 6 is annular, the lower end of the fixing component 2 7 is annular, and the ring at the lower end of the fixing component 2 7 is provided with a notch, the notch is located on the upper side of the ring, and the width of the notch is greater than the width of the fixing component 1 6.

[0027] The lower end of the fixing component 2 7 is annular, and a notch is provided in the ring at the lower end of the fixing component 2 7. The notch is located on the upper side of the ring. The width of the notch is greater than the width of the fixing component 1 6, so that it is convenient to replace the tension rope 5, the fixing component 1 6 or the fixing component 2 7 when they are damaged or need to be replaced.

[0028] Among them, the length of the tension rope 5 is greater than the length between the fixed base plate 1 and the fixed component 29.

[0029] Make sure that the tension rope 5 has sufficient length to perform the test stretching when facing sensors with different length values.

[0030] Among them, both the fixing component three 8 and the fixing component four 9 are provided with fixing holes of the same shape and size. The size and shape of the fixing holes are the same as the upper and lower ends of the tension sensor 10, and the length value of the fixing component four 9 is greater than the length value of the upper end of the tension sensor 10.

[0031] The position of 10 is fixed by fixing the fixing component four 9. The length of the fixing component four 9 is greater than the length of the upper end of the tension sensor 10 to ensure that the tension sensor 10 can be fixed with sufficient supporting force.

[0032] The working principle and use process of this utility model:

[0033] First, determine the tension sensor 10 to be detected, then insert the upper end of the tension sensor 10 into the fixing component four 9 to complete the fixation of the upper end, then move the tension rope 5 along the rotating shaft 4 to the bottom close to the center position of the fixing component four 9, and then fix the fixing component three 8 to the lower end position of the tension sensor 10. After confirming that the upper and lower ends of the tension sensor 10 are fixed, embed the fixing component one 6 into the interior of the fixing component two 7 through the notch on the fixing component two 7 to complete the socketing. Then you can start the motor 3 to rotate and drive the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the tension rope 5 follows the rotation and is wrapped around the surface of the rotating shaft 4. Then the excess part of the tension rope 5 will be completely wrapped around the surface of the rotating shaft 4, and the part between the rotating shaft 4 and the fixing component one 6 becomes tight. At this time, the tension sensor 10 will be affected by the tension. Because the tension is provided by the rotation of the motor 3, it can achieve accurate provision of tension and continuous and stable output, so that the sensor can detect tiny tension changes and provide accurate data.
