Detailed Implementation
[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figures 1-4 A rapid equipment calibration fixture includes a main support frame 1, an auxiliary support frame 2, and several test probes 3. The main support frame 1 is fixedly installed to the equipment 5 to be tested and calibrated via a quick-connect mechanism 4. The auxiliary support frame 2 is fixedly installed on one side of the main support frame 1. The test probes 3 pass through the main support frame 1 and the auxiliary support frame 2 and are installed on the auxiliary support frame 2. The test probes 3 are used to insert into and connect to the connection port of the equipment 5 to be tested and calibrated, and are powered on. Meanwhile, the main support frame 1 is made of metal to ensure sufficient strength; the auxiliary support frame 2 is made of insulating material, which not only increases the strength of the main support frame 1 but also ensures insulation between the test probes 3 and the main support frame 1.
[0026] With the above setup, during actual operation, staff only need to install the fixture onto the device to be tested and calibrated 5 using the quick-connect mechanism 4 to begin the calibration test. After completion, the fixture can be quickly disassembled using the quick-connect mechanism 4 and connected to the next device to be tested and calibrated 5 for the next step. The operation is simple, efficient, and greatly saves working time. Furthermore, due to its simple structure and external mounting on the device to be tested and calibrated 5, it offers a better field of vision and is easier for staff to operate.
[0027] The main support frame 1 includes a mounting part 11 and a connecting part 12. The mounting part 11 has a concave structure, with mounting holes 13 on both sides for the quick-connect mechanism 4 to pass through and be fixed. The connecting part 12 has a flat structure, with the mounting part 11 connected to both ends, and is integrally formed with the mounting part 11, making the structure more stable. At the same time, a top plate 21 is integrally formed at the top of the connecting part 12. When installing this fixture, the top plate 21 should face upwards. The top plate 21 can effectively assist workers in accurate and quick installation.
[0028] The quick-connect mechanism 4 includes a mounting bolt 14 and a limiting nut 15. The limiting nut 15 is fitted onto the mounting bolt 14, which passes through the concave structure of the mounting part 11. The limiting nut is located within the concave structure of the mounting part 11. The mounting bolt 14 enables quick installation and disassembly, while the limiting nut 15 effectively limits movement, preventing the mounting part 11 from shrinking due to compression and ensuring the stability of the overall structure.
[0029] The auxiliary support frame 2 is a flat plate structure and is installed on one side of the connecting part 12 by several fixing bolts 16.
[0030] Specifically, the connecting part 12 of the main support frame 1 has several screw holes 17 and several through holes 18, and the auxiliary support frame 2 has several screw holes 19 and several fixing holes 20. The number of fixing bolts 16, screw holes 17 and screw holes 19 corresponds; the number of test probes 3, through holes 18 and fixing holes 20 corresponds, and can be adjusted as needed in actual use. The fixing bolts 16 pass through screw holes 17 and screw holes 19 to install the auxiliary support frame. The test probes 3 pass through through holes 18 and are installed in fixing holes 20. At the same time, through holes 18 and fixing holes 20 are coaxial circular holes, and the diameter of through holes 18 is larger than the diameter of fixing holes 20, so as to ensure that the test probes 3 only contact the insulated auxiliary support frame 2 and not the metal main support frame 1.
[0031] Specifically, the test probe 3 includes a head 31 and a tail 32; the head 32 is used to insert into the connection port of the calibration device 5 under test, for power connection during calibration; the tail 32 is used for soldering wire harnesses. An annular protrusion 33 is also provided on the outer surface of the test probe 3. When the tail 32 of the test probe 3 is inserted into the fixing hole 20, the annular protrusion 33 can act as a limit. This simple installation method for the test probe 3 and the auxiliary support frame 2 also makes them easier to maintain.
[0032] In actual use, the operator first aligns the mounting bolt 14 with the mating hole on the device end, and then tightens it manually or with a power tool. Simultaneously, the limit nut 15 is adjusted to prevent the side wall of the mounting part 11 from deforming due to pressure against the side of the device 5 to be tested and calibrated. This ensures that the pressure of the connection port of the device 5 against the head 31 of each test probe 3 is consistent, guaranteeing the accuracy of the device calibration. Then, the device calibration test can be started. After the test, the operator simply reverses the direction of the mounting bolt 14 to disassemble the device, then moves to the next device and repeats the above steps to continue the calibration test.
[0033] Moreover, due to its small size, simple structure, and convenient installation, this tooling is also relatively inexpensive. In actual work, multiple tools can be used together to further improve work efficiency.
[0034] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
