The operation is simple, convenient for squeezing and fixing the device under test, and has a good use effect.

[0018] 2. The utility model transmits the external operating force to the contact system of the circuit breaker through the core shaft, so that the moving contact and the static contact are closed or disconnected, thereby realizing the connection or disconnection of the circuit. At the same time, the core shaft drives the hexagonal shaft to rotate, thereby driving the three cams to rotate. The three cams squeeze the three springs. When the cams are away from the springs, the springs will rebound, and this cycle will be repeated. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0027] Refer to the instruction manual Figure 1-5The circuit breaker mechanism automatic test running-in platform of this embodiment includes a running-in platform body 1, an electric control box 2 and a display screen 3, and the electric control box 2 is fixedly installed on the top of the running-in platform body 1, and the display screen 3 is fixedly installed on the front side of the electric control box 2. Four chuck seats 6 are fixedly connected to the front side of the running-in platform body 1, and chucks 7 are movably connected to the four chuck seats 6 through hinge seats. Two test frames 11 are fixedly connected to the inside of the running-in platform body 1, and adjustment components 12 are provided on both sides of the two test frames 11. The four adjustment components 12 each include a mounting seat 1201, a fixed seat 1202 and a cylinder 1203. The four mounting seats 1201 are respectively fixedly installed on the two test frames 11 by multiple bolts, and the four mounting seats 1201 are movably connected to the four fixed seats 1202 by four hinge seats. The two ends of the four cylinders 1203 are respectively fixedly connected to the four fixed seats 1202 and the four chucks 7. A limit plate 5 is movably provided on one side of the four chucks 7, and the four limit plates 5 are all fixedly installed on the front side of the running-in platform body 1.

[0028] Furthermore, the interiors of the two test frames 11 are movably connected to hexagonal shafts 13 through bearings, the front ends of the two hexagonal shafts 13 are fixedly connected to the core shaft 4, three cams 14 are fixedly sleeved on the two hexagonal shafts 13, and springs 15 are movably provided at the bottoms of the multiple cams 14, and the bottom ends of the multiple springs 15 are fixedly connected to the two springs 15 respectively.

[0029] Among them, when closing or opening operations are required, external operating forces such as manual, electric or spring energy storage will be transmitted to the core shaft 4 through a series of transmission mechanisms. The core shaft 4 then transmits this operating force to the contact system of the circuit breaker, so that the moving contact and the static contact are closed or disconnected, thereby realizing the connection or disconnection of the circuit. At the same time, the core shaft 4 drives the hexagonal shaft 13 to rotate, thereby driving the three cams 14 to rotate. The three cams 14 squeeze the three springs 15. When the cams 14 are away from the springs 15, the springs 15 will rebound, and this cycle is repeated. The structure is simple and easy to use.

[0030] Furthermore, a plurality of cable holes 9 are provided on the front side of the running-in platform body 1 to facilitate insertion of cables into the running-in platform body 1 .

[0031] Furthermore, a rear plate 10 is mounted on the rear side of the running-in table body 1 by means of bolts, so as to facilitate maintenance of the internal mechanism of the running-in table body 1 .

[0032] Furthermore, support frames 8 are fixedly connected to the bottom end of the running-in table main body 1 near the four corners to facilitate supporting the running-in table main body 1.

[0033] The method of using this embodiment is:

[0034] During use, the staff places the device to be tested on the front side of the running-in table main body 1, and the limit plate 5 limits the circuit breaker mechanism, and then starts the cylinder 1203. Since one end of the fixed seat 1202 is movably connected to the mounting seat 1201 through a hinge seat, and the other end of the fixed seat 1202 is movably connected to the chuck 7 through a hinge seat, the piston rod on the cylinder 1203 extends to drive the chuck 7 to deflect, and makes the chuck 7 approach the device to be tested, and the device to be tested is squeezed and fixed by the chuck 7. Similarly, the contraction of the piston rod on the cylinder 1203 can drive the chuck 7 away from the device to be tested, thereby releasing the squeezing and fixing of the device to be tested. The operation is simple, convenient for squeezing and fixing the device to be tested, and has a good use effect.

[0035] The workflow of this utility model is:

[0036] Step 1 detects the position of the chuck clamping sensor and the workpiece position sensor. There is no time limit. The detection run is set to 1-9999 times before proceeding to step 2.

[0037] In step 2, the circuit is connected and the energy storage relay works. If the energy storage in place sensor is connected at any time within 30 seconds, proceed to step 3. If the energy storage in place sensor is not connected within 30 seconds, the automatic control process is suspended and the automatic control process is continued after the fault is resolved.

[0038] Step 3: Close the energy storage relay. If it is ready within 3 seconds, proceed to step 4. If it is not ready within 3 seconds, suspend the current automatic control process and continue the current automatic control process after the fault is resolved.

[0039] Step 4: After opening the closing relay for 0.1 seconds, immediately close the closing relay and detect the position of the closing position sensor. If it is ready within 3 seconds, proceed to step 5; if it is not ready within 3 seconds, suspend the current automatic control process and continue the current automatic control process after the fault is resolved.

[0040] After a delay of 3 seconds in step 5, proceed to step 6.

[0041] Step 6: After opening the trip relay for 0.1 seconds, immediately close the trip relay and detect the position of the trip position sensor. If it is ready within 3 seconds, proceed to step 7; if it is not ready within 3 seconds, suspend the current automatic control process and continue the current automatic control process after the fault is resolved.

[0042] Step 7: Turn off all relay outputs and end this automated test process.
