Description

Technical Field

[0001] The utility model relates to the technical field of tensile machine sensors, in particular to a sensor device for a portable tensile machine. Background Art

[0002] The sensing devices of a portable tensile testing machine typically include strain gauges, force sensors, and displacement sensors. Strain gauges measure force by detecting deformation; force sensors directly convert force into an electrical signal; and displacement sensors measure changes in specimen displacement, thereby calculating relevant data during the tensile or compression process. These sensors generally feature high sensitivity, high accuracy, and excellent stability.

[0003] Portable tensile testing machines (PTMs) have become indispensable tools in modern industrial production and materials testing due to their flexibility and efficiency. These precision instruments demonstrate exceptional accuracy and stability in measuring key parameters such as tensile strength and breaking point. However, an often overlooked yet crucial aspect of using a portable tensile testing machine is the safety and protection of its sensor assembly.

[0004] Specifically, the sensor device of a portable tensile testing machine is a core component responsible for capturing and converting the mechanical signals generated by the material during the stretching process, deriving test results through data analysis. However, this precision component faces multiple potential threats during operation. To prevent these threats from damaging the sensor device and thus affecting test accuracy and overall equipment performance, engineers have installed protective plates on the side walls of the sensor device to provide necessary protection.

[0005] First, from a design perspective, the structural design of some guard plates is overly simplistic, failing to fully account for the complexities of actual use. For example, in certain environments, such as high temperature, high humidity, or highly corrosive media, the material properties of the guard plates may be severely affected, significantly reducing their protective effectiveness. Furthermore, the guard plates' installation location and fixing method may be unreasonable, rendering them ineffective when subjected to external impacts.

[0006] Secondly, from a user's perspective, the protective performance of the guard plate is also affected by human factors. For example, if personnel fail to strictly follow operating procedures and improperly remove, install, or maintain the guard plate during operation, the guard plate's protective performance may be degraded or even rendered ineffective. Furthermore, long-term use and wear may cause the guard plate to break or deform, further compromising its protective effectiveness. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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. Example

[0029] In modern industry and scientific research, portable tensile testing machines are essential testing equipment. Their accuracy and stability are directly related to the reliability of test results. The design and manufacture of sensors, core components of tensile testing machines, are crucial. This article will delve into an innovative sensor device for portable tensile testing machines. It features not only a unique structure but also a high degree of precision and user-friendly design in its detailed design.

[0030] See also Figure 1 - Figure 4 As shown in the figure, the sensing device mainly consists of a tension sensor body 1, an interface 2, a wire 3, a connecting bar 4, a fixing plate 5, a bent portion 6, a tightening bar 7, a notch 8, an elastic bar 9, an adjustment plate 10, and a through hole 11. These components work together to form this efficient and stable sensing device.

[0031] The tension sensor body 1 is the core of the entire device, and its performance directly determines the accuracy of test data. To ensure stable operation of the sensor body, the designers cleverly designed a port 2 on its sidewall, ensuring a tight connection between port 2 and the sensor body through a sealed connection. Furthermore, to prevent damage to port 2 from external factors such as dust and moisture, a sealing rubber ring was installed at the connection between port 2 and wire 3, further enhancing the device's protection.

[0032] Next, let's consider the design of the connecting strip 4 and the fixing plate 5. These two parts are designed as an integrated whole, which not only simplifies the installation process, but also greatly improves the overall strength of the device. The connecting strip 4 is firmly fixed to the tension sensor body 1, while the fixing plate 5 is connected to the sensor body through the bend 6. The design of the bend 6 is particularly ingenious. It can not only effectively disperse stress and prevent the pressing strip 7 from excessively contacting the surface of the sensor body, but also fits tightly with the pressing strip 7 through its unique "Ω"-shaped cross-section design to form a stable support structure.

[0033] The abutment strip 7, a crucial component of the fixing plate 5, features a C-shaped cross-section and is constructed from a resilient metal sheet. This design allows the strip 7 to deform when subjected to external forces, allowing it to better adapt to test objects of varying shapes and sizes. Furthermore, the strip's elastic properties effectively reduce noise and errors caused by vibration or impact, ensuring the accuracy of test results.

[0034] At the lower end of the fixing plate 5, the designer cleverly designed a notch 8, which is connected to the adjustment plate 10 via an elastic strip 9. The end surface of the adjustment plate 10 features multiple through-holes 11, arranged in an array, allowing the user to select the appropriate bolts for installation. To adjust the test position or change the test object, the user simply flips the bend 6 to expose the through-holes 11, enabling quick and convenient installation.

[0035] Furthermore, the elastic strip 9 and adjustment plate 10 also feature an integrated design, constructed from resilient sheet metal. This design not only ensures that the adjustment plate 10 can deform sufficiently to accommodate various installation requirements when subjected to external forces, but also alleviates fatigue caused by prolonged use. Furthermore, a certain gap is maintained between the adjustment plate 10 and the tension sensor body 1, which not only helps reduce heat and noise generated by friction but also improves the device's heat dissipation and service life.

[0036] In summary, the structural design of this sensor device for portable tensile testing machines fully considers practicality, stability, and convenience. By employing an integrated design, sealed connections, elastic metal sheet materials, and a unique design of the bent portion 6 and adjustment plate 10, the device not only achieves efficient and stable testing but also provides users with a more convenient and flexible installation and use experience. We believe that this sensor device will play an even more important role in future industrial and scientific research fields.

[0037] The installation process is as follows: Ensure all components (tensile sensor body 1, interface 2, wire 3, connecting bar 4, fixing plate 5, bend 6, abutment bar 7, notch 8, elastic bar 9, adjustment plate 10, and through-hole 11) are present and in good condition. Installing the tensile sensor body 1: Place the tensile sensor body 1 in the intended installation location, ensuring it is stable and secure. Connecting the interface 2 and wire 3: Secure the interface 2 to the side wall of the tensile sensor body 1 using a sealed connection, ensuring a leak-proof connection. Then, connect the wire 3 to the sensor body through the interface 2, ensuring that the sealing rubber ring is installed at the connection to prevent external damage. Installing the connecting bar 4 and fixing plate 5: Secure the connecting bar 4 to the tensile sensor body 1. Then, connect the fixing plate 5 to the sensor body through the bend 6. Ensure that the "Ω"-shaped cross-section of the bend 6 fits tightly against the abutment bar 7 to form a stable support structure.

[0038] Align the "C"-shaped cross-section of the abutment strip 7 with the fixed plate 5, ensuring that the elastic metal sheet can accommodate test objects of varying shapes and sizes. Install the adjustment plate 10 and elastic strip 9: Connect the elastic strip 9 to the fixed plate 5 through the notch 8, ensuring that the elasticity of the elastic strip 9 can support the deformation of the adjustment plate 10. Then, install the adjustment plate 10 on the elastic strip 9, ensuring that the through-holes 11 face the user to facilitate subsequent bolt installation.

[0039] Select appropriate bolts based on actual needs and securely attach adjustment plate 10 to the mounting location (such as a test bench or fixture) through through-holes 11. After completing all installation steps, thoroughly inspect the sensor device to ensure that all components are correctly installed and tightly fitted. Subsequently, perform necessary debugging to ensure the sensor device is functioning properly and accurately reading test data. After inspection and debugging, the sensor device is put into actual use, and any necessary adjustments and optimizations are performed based on the test results.
