[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] like Figure 1 - Figure 4 As shown, an adjustable rebound hammer calibration device mainly includes a docking station 2, a rebound calibration detection component 3, a force sensor 4, and an edge guide 5. These components and devices each play a unique role and work together to complete the rebound calibration operation.
[0028] The docking station 2 is the core structure of the entire device, supporting the installation of the rebound calibration detection assembly 3 and the edge guide 5. The rebound calibration detection assembly 3 is installed on the docking station 2 to perform the primary task of rebound calibration. The edge guide 5 is located at each end of the docking station 2 and provides guidance and positioning.
[0029] A force sensor 4 is also mounted on one of the edge guides 5. The force sensor 4 is adapted to the rebound calibration detection assembly 3 and can accurately measure and record force changes during the calibration process, providing accurate data support for the rebound calibration.
[0030] To ensure stability and flexibility, the docking station 2 is connected to the slide rail 8 via a slider 10. An adjustment station 1 is mounted at the lower end of the slide rail 8, allowing for easy position adjustment of the entire device. One end of the adjustment station 1 is equipped with a connecting block 6, which is mounted on an adjustment screw 7. By turning the adjustment screw 7, the docking station 2 can be moved along the slide rail 8, thereby fine-tuning the rebound calibration detection assembly 3 and the load cell 4.
[0031] For fastening, the end surfaces of both the docking base 2 and the adjustment base 1 are provided with multiple waist holes 11. To secure the device, simply insert fasteners 12 into two aligned waist holes 11. These fasteners 12 consist of bolts, nuts, and washers. By turning the nuts, the washers press against the surface of the adjustment base 1, securing the docking base 2 and adjustment base 1.
[0032] The connecting block 6 and the adjustment base 1 are integrated into one unit, ensuring structural stability and simplifying assembly. The adjustment screw 7 is comprised of a screw, a handle, and a push plate. The handle and push plate are bolted to each end of the screw. This design facilitates operation of the adjustment screw 7, allowing the push plate to directly contact the edge guide 5 for fine-tuning.
[0033] Furthermore, two parallel rails 8 are mounted on the adjustment base 1, ensuring the stability of the docking base 2 during movement. Four sliders 10 are located at the four corners of the lower end of the docking base 2 and engage with the slots 9 at the upper ends of the rails 8. The sliders 10 and slots 9 utilize a T-key and T-slot structure, ensuring smooth and stable sliding. Furthermore, the smooth surfaces of the sliders 10 and rails 8 reduce friction and extend the life of the device.
[0034] The waist holes 11 are evenly spaced on the docking seat 2 and the adjustment seat 1. This design not only ensures the uniformity of the structure but also facilitates the installation of the fasteners 12. The bolt diameter of the fastener 12 is consistent with the width of the waist hole 11, ensuring the tightness and stability of the installation.
[0035] This adjustable rebound hammer calibration device achieves both precision and flexibility in rebound calibration through its unique structural design and component configuration. Whether in scientific research or engineering applications, it plays an important role, providing reliable support for rebound calibration.
[0036] Instructions: The user must ensure that the adjustable rebound hammer calibration device is in good condition, with no damaged or missing components or devices. Next, the user will perform preliminary adjustments based on specific needs. By turning the adjustment screw 7 on the adjustment base 1, the docking base 2 moves on the slide rail 8, thereby achieving the initial positioning of the rebound calibration test assembly 3 and the load cell 4.
[0037] During the adjustment process, the user needs to carefully observe the relative position between the rebound calibration detection assembly 3 and the rebound hammer to be calibrated to ensure that the two are accurately aligned. At the same time, the edge guide device 5 plays a guiding and positioning role, helping the user to adjust the device position more accurately.
[0038] After completing the initial adjustment, the user needs to secure the device. Insert fasteners 12 into the two aligned waist holes 11 and turn the nuts to force the washers against the surface of the adjustment base 1, thereby firmly securing the docking base 2 and the adjustment base 1. During the securing process, the user must ensure that fasteners 12 are securely installed to prevent them from loosening or falling off during use.
[0039] After the fixation is completed, the user can place the rebound hammer to be calibrated on the rebound calibration detection assembly 3 and start the calibration process. During the calibration process, the force sensor 4 will measure and record the force value changes of the rebound hammer in real time, providing the user with accurate calibration data.
[0040] After the calibration is completed, the user can fine-tune the device as needed to obtain a more accurate calibration result. During the fine-tuning process, the user can fine-tune the docking seat 2 by adjusting the screw 7, and after adjustment, it can be fixed by the fastener 12.
[0041] Finally, the user needs to clean and maintain the device to ensure it is in good working condition the next time it is used. At the same time, the user also needs to calibrate and inspect the device regularly to ensure its long-term stability and reliability.
