Description

Technical Field

[0001] This utility model belongs to the technical field of sensor performance testing equipment, and in particular relates to a force sensor bandwidth testing device. Background Technology

[0002] The bandwidth of a force sensor determines the highest frequency signal it can accurately measure. A wider bandwidth means the sensor can better capture rapidly changing force signals (such as dynamic loads like impacts and vibrations), while insufficient bandwidth can lead to high-frequency signal attenuation or distortion, affecting the accuracy of dynamic force measurements. Therefore, bandwidth detection is a crucial step in evaluating its dynamic performance, primarily achieved by using bandwidth detection equipment to perform frequency response tests to obtain bandwidth data.

[0003] In related technologies, the motor in bandwidth detection equipment directly applies torque to the sensor. The rated torque of the motor limits the detection torque that can be applied to the sensor. When the sensor's measuring torque exceeds the motor's torque, a motor with a higher torque is required to meet the detection needs. Therefore, there is a problem of a narrow range of sensors that can be used for detection. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0026] like Figure 1 and Figure 2 As shown in the illustration, a force sensor bandwidth detection device 1 provided in this embodiment of the invention is used to detect the bandwidth of a force sensor in order to evaluate its detection performance. Specifically, force sensors are used to detect changes in force or torque and are commonly used in robots, aircraft, or automobiles. The bandwidth of a force sensor refers to the frequency range it can respond to, that is, the force sensor's ability to respond to input signals of different frequencies, defined as the upper frequency limit at which the output response drops to 70.7% of the maximum response. The wider the bandwidth, the faster the dynamic changes can be monitored, and the higher the ability to track rapidly changing forces. For example, in high-frequency vibration or dynamic force measurement scenarios, a high-bandwidth force sensor can more accurately capture signal changes. Therefore, the force sensor bandwidth detection device 1 is used to evaluate and detect the bandwidth of the force sensor to prevent the installed force sensor's bandwidth from being mismatched with the application scenario's requirements, thereby affecting the reliability of actual use.

[0027] like Figure 1 and Figure 2As shown in the figure, the force sensor bandwidth detection device 1 provided in this embodiment of the present invention includes a frame 11, a mounting frame 12, a detection component 13, a control component 14, and a force-applying rod 15. The frame 11 is the supporting base of the entire detection device, used to support the installation and fixation of other components of the device. The mounting frame 12 is disposed on the frame 11 and is used for connecting and fixing the sensor 2 to be tested. That is, the sensor 2 to be tested is connected and fixed on the mounting frame 12 to achieve the fixation preparation before testing.

[0028] The detection component 13 is connected to the adjacent mounting bracket 12 on the frame 11. The detection component 13 is used to apply a detection force to the sensor 2 under test. Specifically, the detection component 13 can output a corresponding detection force according to the detection needs. When this detection force is applied to the sensor 2 under test, the sensor 2 under test can simulate the force under actual use, thereby obtaining the detection information of the bandwidth performance of the sensor 2 under test.

[0029] Specifically, the detection component 13 can provide detection force by extending or pulling the force-applying rod 15, thereby adjusting the magnitude of the detection force by controlling the amount of extension or retraction. Alternatively, it can provide detection force by rotating and squeezing the force-applying rod 15, thereby adjusting the magnitude of the detection force by controlling the angle of rotation. The specific setting can be selected and configured according to the actual detection needs.

[0030] The control component 14 is electrically connected to the detection component 13. The control component 14 controls the detection force output by the detection component 13 based on information from the sensor 2 under test. Specifically, the information of the sensor 2 under test can refer to its measurable range or its ability to measure spatial force components (e.g., one-dimensional, two-dimensional, three-dimensional, or six-dimensional). Six-dimensional measurement refers to simultaneously measuring forces (Fx, Fy, Fz) in three directions and torques (Mx, My, Mz) in three directions. For example, with different ranges, the magnitude of the detection force acting on the sensor 2 under test will also differ. That is, different ranges of the sensor 2 under test result in different maximum detection forces. Typically, the detection force is applied based on 1% to 3% of the rated range of the sensor 2 under test. Therefore, by setting the control component 14, the magnitude of the detection force output by the detection component 13 can be controlled according to the type of sensor 2 under test, and the output detection force is monitored in real time by a monitor to ensure the accuracy of the output detection force. In this way, not only are the detection needs met, but the detection force can also be adjusted according to different detection requirements, thereby increasing the range of types of sensors 2 that can be used for detection.

[0031] The force-applying rod 15 is connected to the sensor 2 under test and abuts against the detection component 13. The force-applying rod 15 is used to increase the detection force acting on the sensor 2 under test. Specifically, the force-applying rod 15 can be fixedly or detachably connected to the sensor 2 under test. The force-applying rod 15 effectively increases the lever arm length of the detection component 13 acting on the sensor 2 under test, thus amplifying the detection force output by the detection component 13 before it acts on the sensor 2 under test. This configuration, by amplifying the detection force via the force-applying rod 15, not only improves the detection sensitivity but also increases the maximum output detection force even with the same detection component 13, thereby increasing the detection range applicable to the sensor 2 under test (enabling the detection of the bandwidth of the sensor 2 requiring greater torque). In this way, the range of sensors 2 that can be detected is expanded, effectively solving the problem of the narrow measurement range of the force sensor bandwidth detection device 1.

[0032] The force sensor bandwidth detection device 1 provided in this embodiment includes a frame 11, a mounting bracket 12, a detection component 13, a control component 14, and a force-applying rod 15. The mounting bracket 12 is mounted on the frame 11 and used for connecting and fixing the sensor 2 to be detected. The detection component 13 is used to apply a detection force to the sensor 2. The control component 14 is used to control the detection force output by the detection component 13 based on information from the sensor 2. The force-applying rod 15 is used to increase the detection force acting on the sensor 2. Thus, by setting the control component 14, the magnitude of the detection force output by the detection component 13 can be adjusted. Simultaneously, by combining the force-applying rod 15, the output detection force can be amplified. Therefore, the force sensor bandwidth detection device 1 can not only adjust the output detection force according to the object being detected but also amplify the detection force, thereby enabling the detection of force sensor bandwidths with different ranges, increasing the range of detection capabilities, and effectively solving the problem of the narrow measurement range of the force sensor bandwidth detection device 1.

[0033] In some embodiments, such as Figure 1 and Figure 2As shown, the detection component 13 includes a force-applying element 131 and an eccentric wheel 132. The force-applying element 131 generates a detection force, specifically by rotation. Therefore, the force-applying element 131 can be a motor, pneumatic motor, or hydraulic motor capable of providing rotational motion. The eccentric wheel 132 is connected to the drive shaft of the force-applying element 131, and the eccentric wheel 132 abuts against the force-applying rod 15. In this way, the force-applying element 131 drives the eccentric wheel 132 to perform eccentric motion. As the eccentricity of the eccentric wheel 132 gradually increases, it compresses the force-applying rod 15, causing the force-applying rod 15 to move and apply a detection force to the sensor 2 to be detected. The rotation speed and mode of the force-applying element 131 are controlled by the control component 14, thereby generating a detection force of a corresponding frequency according to the control information, so as to realize the detection of the bandwidth of the sensor 2 to be detected. This method generates detection force through eccentric motion, has a simple structure, and allows for convenient frequency control of the applied detection force, thus effectively meeting the detection needs for high-frequency conversion of detection force.

[0034] Specifically, the combination of the force-applying component 131 and the eccentric wheel 132, under the control of the control component 14, controls the eccentric wheel 132 to apply a sinusoidal force signal to the force-applying rod 15 by rotating the force-applying component 131 at different angles. The signal frequency gradually increases over time, and the amplitude attenuation ratio and phase lag angle of the force sensor relative to the sinusoidal force signal are monitored in real time. The bandwidth can be calculated by the PLC (Programmable Logic Controller) or host computer software using preset formulas and the monitored data.

[0035] Specifically, the calculation formula is as follows: Where B is the bandwidth frequency, 2π is one motion cycle, and Δt is the lag time. The lag time is inversely proportional to the bandwidth; the larger the lag time Δt, the smaller the bandwidth. The lag time Δt can be determined by comparing the time difference between the application of the detection force by the force-applying component 131 and the response of the sensor 2 to be detected.

[0036] In some embodiments, the force-applying rod 15 and the sensor 2 under test are detachably connected, allowing the force-applying rod 15 to be adjusted according to testing needs, such as selecting the length of the force-applying rod 15. Specifically, one end of the force-applying rod 15 is detachably connected to the sensor 2 under test, and the other end of the force-applying rod 15 extends toward the eccentric wheel 132, with the axial direction of the force-applying rod 15 intersecting the axial direction of the eccentric wheel 132. That is, the eccentric wheel 132 is located on the side of the axial direction of the force-applying rod 15 and has an included angle, such as an acute angle or a right angle. In this way, there is a large contact area between the eccentric wheel 132 and the force-applying rod 15, thereby enabling the eccentric wheel 132 to reliably apply the detection force to the force-applying rod 15. Of course, in another possible implementation, provided that the diameter of the extension rod 15 is large enough to provide a reliable contact area, the axial direction of the eccentric wheel 132 can also be set parallel to the axial direction of the extension rod 15, which can also reliably drive the extension rod 15 to move.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the detection assembly 13 also includes a transmission rod 133 and a bearing support 135. The transmission rod 133 is equivalent to extending the length of the drive shaft of the force-applying component 131. One end of the transmission rod 133 is connected to the drive shaft of the force-applying component 131 via a coupling 134, and the eccentric wheel 132 is connected to the other end of the transmission rod 133. The bearing support 135 is connected to the frame 11, and the transmission rod 133 passes through the bearing support 135. In this way, the rotation of the transmission rod 133 is limited and guided by the bearing support 135, resulting in good transmission stability and enabling stable and reliable rotation of the eccentric wheel 132.

[0038] Specifically, the bearing support 135 includes a bearing housing bracket connected to the frame 11, a bearing housing mounted on the bearing housing bracket, and a bearing mounted inside the bearing housing. The transmission rod 133 passes through the bearing, providing support and rotation guidance through the bearing, thus ensuring smooth rotation. Moreover, multiple bearing housings can be installed on the bearing housing bracket as needed according to support requirements, with multiple bearings guiding rotation, further improving the smoothness and reliability of rotation.

[0039] In some embodiments, such as Figure 1 and Figure 2As shown, the force sensor bandwidth detection device 1 also includes an adapter block 16. The adapter block 16 is used to transmit the detection force to the sensor 2 under test. The adapter block 16 is connected to the sensor 2 under test, and the force-applying rod 15 is connected to the adapter block 16. With this configuration, the adapter block 16 has a large working area. By using the adapter block 16 for the installation of the force-applying rod 15, the force-applying rod 15 does not need to be directly installed on the sensor 2 under test. The installation connection between the force-applying rod 15 and the adapter block 16, as well as the installation connection between the adapter block 16 and the sensor 2 under test, both have a large contact area, thus making installation convenient and providing good stability.

[0040] In some embodiments, such as Figure 1 As shown, the mounting bracket 12 is detachably connected to the frame 11 via a connecting structure. Furthermore, the mounting bracket 12 is configured in various specifications according to the type of sensor 2 to be tested. Since different types of sensors 2 may differ in size, the structure used for connecting and fixing to the mounting bracket 12, and the connection method, the same mounting bracket 12 cannot meet the connection and fixing requirements of different types of sensors 2. Therefore, by setting a connecting structure to create a detachable connection between the mounting bracket 12 and the frame 11, assembly and disassembly are convenient. Moreover, by setting the specifications of the mounting bracket 12 according to the installation requirements of different types of sensors 2 to be tested, the appropriate mounting bracket 12 can be selected for connection and fixing according to the different types of sensors 2 to be tested (such as single-dimensional force sensors, three-dimensional force sensors, six-dimensional force sensors, etc.), thereby increasing the types of sensors 2 that the testing equipment can use to test and expanding the scope of testing applications.

[0041] Specifically, the connection structure can be achieved by providing through holes on both the mounting bracket 12 and the frame 11, and then passing the connecting end of the bolt through the two through holes until it protrudes, before connecting with a nut to achieve a fixed connection. Alternatively, the mounting bracket 12 can have threaded holes, and the frame 11 can have either threaded holes or through holes, with the connecting end of the bolt inserted into the threaded hole on the mounting bracket 12 to achieve a detachable connection between the mounting bracket 12 and the frame 11, providing good connection convenience.

[0042] In some embodiments, such as Figure 1 and Figure 2As shown, the adapter block 16 is provided with a limiting block 161 for limiting the rotation angle of the sensor 2 under test during detection. Specifically, during the detection process, the detection force acting on the force rod 15 will drive the adapter block 16 to rotate at a certain angle relative to the mounting bracket 12. Therefore, by providing the limiting block 161 on the adapter block 16, when the limiting block 161 collides with at least one of the mounting bracket 12, the frame 11, or other provided stop structures, further movement of the adapter block 16 can be limited, thereby preventing the sensor 2 under test from being excessively twisted and damaged during the detection process, and improving the safety of the detection.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, a limiting block 161 is positioned on top of the adapter block 16 and extends towards the mounting bracket 12, allowing it to abut against the top of the mounting bracket 12 for limiting movement. This design directly utilizes the top of the mounting bracket 12 as a stop structure. Once the limiting block 161 abuts against the top of the mounting bracket 12, further rotation of the adapter block 16 is restricted, thus achieving the limiting function and protecting the sensor 2 under test. Furthermore, a detection gap 18 exists between the limiting block 161 and the top of the mounting bracket 12. This detection gap 18 allows the adapter block 16 sufficient rotational space during the detection process, enabling it to rotate for detection. Simultaneously, this detection gap 18 does not compromise the protection against excessive rotation of the sensor 2 under test; therefore, the height of the detection gap 18 can be calculated based on the rotation angle and radius, demonstrating ingenious design.

[0044] In some embodiments, such as Figure 1 As shown, the control assembly 14 includes a touch box 141, an accessory box 142, and a control switch 143. The touch box 141 is mounted above the frame 11 and includes a touchscreen 1411 for adjusting detection parameters based on the sensor being detected. The accessory box 142 is mounted below the touch box 141 and is used to house electrical control components. Both the detection assembly 13 and the touchscreen 1411 are electrically connected to the accessory box 142. The control switch 143 is mounted on the touch box 141 and is used for start / stop control of the force sensor bandwidth detection device 1. Specifically, the electrical control components installed in the accessory box 142 can be at least one of a servo inverter, an analog acquisition module, a PLC (Programmable Logic Controller), a power filter, an isolated power supply, etc. The touchscreen 1411 is used to directly adjust detection parameters, record detection data, and display relevant data. During the testing process, by combining the various electronic control components in the touch box 141 and the accessory box 142, relevant control signals are executed and data is processed, thereby enabling reliable testing of the bandwidth of the currently installed sensor 2 under test.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the force sensor bandwidth detection device 1 also includes a support plate 17. The support plate 17 is mounted on the frame 11, and both the mounting bracket 12 and the detection component 13 are mounted on the support plate 17. The arrangement of the support plate 17 ensures that both the mounting bracket 12 and the detection component 13 are mounted on the support plate 17, thus not damaging the structure of the frame 11 and helping to ensure the strength of the frame 11 structure. Moreover, during assembly, the mounting bracket 12 and the detection component 13 can be installed on the support plate 17 first, and then the support plate 17 can be installed on the frame 11, which helps to improve the convenience and efficiency of installation. Furthermore, an adjustment groove 171 is provided on the support plate 17, and the mounting bracket 12 is connected in the adjustment groove 171 to adjust the relative position between it and the detection component 13. Specifically, the length direction of the adjustment groove 171 is parallel to the axial direction of the transmission rod 133, and the adjustment groove 171 extends away from the force-applying member 131. Therefore, by connecting the mounting bracket 12 to the adjustment slot 171, the position of the mounting bracket 12 relative to the detection component 13 can be adjusted according to the detection needs, so as to meet the position adjustment requirements under different detection conditions and improve the user experience for detection.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
