Description

Technical Field

[0001] This utility model relates to the field of rivets, specifically to a high-precision device for measuring rivet height. Background Technology

[0002] A rivet is a cylindrical metal fastener with a cap at one end, used to connect two parts or components with through holes. Its core function is to achieve permanent fastening through its own deformation or interference fit. It is widely used in aerospace, construction bridges, electronics and electrical appliances and other fields. A rivet height measuring device is a measuring tool for controlling the rivet height. The measurement of rivet height must ensure accuracy and efficiency, as the rivet height directly affects the stability, safety and fatigue life of the connected parts.

[0003] Existing rivet height measuring devices rely solely on manual measurement with a ruler, resulting in insufficient accuracy to meet the high-precision measurement requirements of fields such as precision instruments. Furthermore, the overall accuracy is limited, leading to poor environmental adaptability and low measurement accuracy over long-term use. This ultimately affects the safety and accuracy of subsequent rivet connection equipment.

[0004] Therefore, it is necessary to invent a high-precision device for measuring rivet height to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision rivet height measuring device. It achieves high-precision measurement by comparing two measurement methods through a main scale line, a drive display controller, a positioning scale, a first measuring plate, a secondary scale line, a first positioning measuring frame, and a first laser spacing measuring head. The resulting measurement data allows the rivet height measuring device to perform high-precision measurements. The dual-mode design of manual physical measurement and laser measurement meets the high-precision industrial requirements and adapts to complex working conditions. Furthermore, while retaining the flexibility of traditional measurement, the device overcomes the precision limitations of manual measurement through laser technology, thus meeting the high-precision measurement needs. This addresses the problem that existing rivet height measuring devices rely solely on manual measurement with a ruler, resulting in insufficient accuracy and failing to meet the high-precision measurement requirements of fields such as precision instruments. The overall accuracy is also limited, leading to poor environmental adaptability and low measurement accuracy over long-term use, which affects the safety and accuracy of subsequent rivet connection equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision rivet height measuring device, comprising a main measuring body and a main body for measuring rivet height;

[0007] The main scale lines are set on both sides of the outside of the main measuring body for physical measurement. A drive display controller is fixedly installed on the top of the main measuring body. Positioning scales are fixedly installed on the outside of the main measuring body. A lower positioning base is fixedly installed on the bottom of the main measuring body.

[0008] The first measuring plate is slidably connected to the right side of the main measuring body for spacing adjustment, and a fixing knob is threaded through the top of the main measuring body. Subscale lines are provided on both outer sides of the first measuring plate.

[0009] The first positioning measuring frame is fixedly installed at the bottom of the first measuring plate for measurement and positioning. A first laser spacing measuring head is fixedly installed on the outside of the first positioning measuring frame. The second measuring plate is slidably connected to the left side of the main measuring body.

[0010] Preferably, a telescopic cylinder is fixedly installed inside the lower positioning base, and an abutment rod is fixedly installed at the bottom end of the telescopic cylinder.

[0011] Preferably, a mounting plate is fixedly installed at the bottom end of the abutment rod, a fixing bolt is threaded through the top of the mounting plate, and a rivet positioning seat is threaded at the bottom end of the fixing bolt.

[0012] Preferably, the rivet positioning seat is threadedly connected to the mounting plate, and the mounting plate and the abutment rod are vertically distributed.

[0013] Preferably, the first measuring plate is slidably connected to the main measuring machine body, and the first positioning measuring frame and the first measuring plate are integrated into a single structure.

[0014] Preferably, a second positioning measuring frame is fixedly installed on the bottom of the second measuring plate, and a second laser spacing measuring head is fixedly installed on the outside of the second positioning measuring frame.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model is equipped with a main scale line, a drive display controller, a positioning scale, a first measuring plate, a secondary scale line, a first positioning measuring frame, and a first laser spacing measuring head. When using this rivet height measuring device, after positioning the rivet, the fixing knob can be turned to adjust the first and second measuring plates by stretching. The rivet height is first measured manually using the main and secondary scale lines. Then, the first measuring plate is adjusted so that the first positioning measuring frame and the first laser spacing measuring head directly emit laser light onto the rivet. The first laser spacing measuring head is then connected to the drive display controller to transmit the measured spacing height data to the drive display controller for viewing. By comparing the two measurement methods, the resulting measurement data allows the rivet height measuring device to achieve high-precision measurement. The dual-mode design of manual physical measurement and laser measurement meets the high-precision industrial requirements and is also adaptable to complex working conditions. Moreover, while retaining the flexibility of traditional measurement, the rivet height measuring device breaks through the precision of manual measurement through laser technology, thus meeting the high-precision measurement requirements.

[0017] 2. This utility model includes a lower positioning base, a telescopic cylinder, a contact rod, a mounting plate, fixing bolts, and a rivet positioning seat. When using this rivet height measuring device, a matching rivet positioning seat can be selected according to the size of the rivet. By extending the telescopic cylinder and the contact rod, the rivet positioning seat is fixed on the periphery of the rivet. Thus, with the rivet as the center, a positioning reference point is provided for the rivet height measuring device during laser irradiation measurement. After adjusting the distance between the first positioning measuring frame and the first laser distance measuring head, the laser can be directly emitted to irradiate the rivet, thereby completing the rivet height measurement. This forms a measurement coordinate system with the rivet as the center, eliminating measurement errors caused by rivet tilting or displacement, and is suitable for measurement of complex structural parts or in vibration environments.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The high-precision rivet height measuring device shown includes a main measuring body 1, which is the main body used for rivet height measurement.

[0028] The main scale line 2 is set on both sides of the outside of the main measuring body 1 for physical measurement. A drive display controller 3 is fixedly installed on the top of the main measuring body 1. Positioning scale 4 is fixedly installed on the outside of the main measuring body 1. A lower positioning base 5 is fixedly installed on the bottom of the main measuring body 1.

[0029] The first measuring plate 11 is slidably connected to the right side of the main measuring body 1 for spacing adjustment, and a fixing knob 12 is threaded through the top of the main measuring body 1. Subscale lines 13 are provided on both sides of the outside of the first measuring plate 11.

[0030] The first positioning measuring frame 14 is fixedly installed at the bottom of the first measuring plate 11 for measurement and positioning. The first laser spacing measuring head 15 is fixedly installed on the outside of the first positioning measuring frame 14. The second measuring plate 16 is slidably connected to the left side of the main measuring body 1. The first measuring plate 11 is adjusted so that the first positioning measuring frame 14 and the first laser spacing measuring head 15 directly emit laser light, which is irradiated on the rivet. Then the first laser spacing measuring head 15 will connect with the drive display controller 3 to transmit the measured spacing height data to the drive display controller 3 for viewing.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, a telescopic cylinder 6 is fixedly installed inside the lower positioning base 5. A contact rod 7 is fixedly installed at the bottom end of the telescopic cylinder 6. By extending the telescopic cylinder 6 and the contact rod 7, the rivet positioning seat 10 is fixed around the rivet. In this way, with the rivet as the center, a positioning base point is provided for the rivet height measuring device during laser irradiation measurement. A mounting plate 8 is fixedly installed at the bottom end of the contact rod 7. A fixing bolt 9 is threaded through the top of the mounting plate 8. The bottom end of the fixing bolt 9 is threadedly connected to the rivet positioning seat 10. The rivet positioning seat 10 can be selected according to the size of the rivet. The rivet positioning seat 10 is threadedly connected to the mounting plate 8. The mounting plate 8 and the contact rod 7 are perpendicularly distributed. The structure of the rivet positioning seat 10 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to replace it in time.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, the first measuring plate 11 is slidably connected to the main measuring body 1. The first positioning measuring frame 14 and the first measuring plate 11 are integrated into one structure. The fixing knob 12 can be turned to adjust the first measuring plate 11 and the second measuring plate 16 by stretching. The height of the rivet is measured manually by referring to the main scale line 2 and the secondary scale line 13. The bottom of the second measuring plate 16 is fixedly installed with the second positioning measuring frame 17. The outside of the second positioning measuring frame 17 is fixedly installed with the second laser spacing measuring head 18. The second laser spacing measuring head 18 and the second positioning measuring frame 17 can also emit lasers to irradiate the rivet and complete the height measurement, just like adjusting the first positioning measuring frame 14 and the first laser spacing measuring head 15.

[0033] The working principle of this practical device is as follows: First, connect the external power supply. Hold the rivet height measuring device and align the positioning scale 4 on the outside of the main measuring body 1 with the outside of the rivet. Then, turn the fixing knob 12 to adjust the first measuring plate 11 and the second measuring plate 16 by stretching. This allows for distance calculation based on the main scale line 2 and the secondary scale line 13, completing the manual physical rivet height measurement. Next, select the matching rivet positioning seat 10 according to the rivet size. Then, turn on the switch of the telescopic cylinder 6. Through the extension of the telescopic cylinder 6 and the contact rod 7, the rivet positioning seat 10 is fixed to the periphery of the rivet. This provides a positioning base point for the rivet height measuring device during laser irradiation measurement, with the rivet as the center. Then, continue to adjust the first measuring plate 11 so that the first positioning measuring frame 14 abuts above the rivet height. At this time, the first positioning measuring frame 14 and the first laser distance measuring head 15 are directly aligned. A laser beam is emitted and irradiates the rivet. Then, the first laser spacing measuring head 15 connects to the drive display controller 3 to transmit the measured spacing height data to the drive display controller 3 for viewing. By comparing the two measurement methods, the resulting measurement data allows the rivet height measuring device to achieve high-precision measurement. The dual-mode design of manual physical measurement and laser measurement meets the needs of high-precision industry and is also adaptable to complex working conditions. Moreover, while the first positioning measuring frame 14 and the first laser spacing measuring head 15 are measuring the upward height of the rivet, the second positioning measuring frame 17 and the second laser spacing measuring head 18 can also be adjusted to measure the downward height of the rivet. Finally, after completing all the installation and use of the rivet height measuring device according to the above operations, the switch of the telescopic cylinder 6 is turned off. If it is not used for a long time, the external power supply can be cut off. In this way, the use process of the high-precision rivet height measuring device is completed.
