Description

Technical Field

[0001] This utility model relates to the field of switch characteristic testing technology, and in particular to a switch characteristic testing device. Background Technology

[0002] Switches are crucial components in power systems. The mechanical characteristics of a switch refer to the motion parameters and mechanical properties exhibited by the switching equipment during opening and closing operations, including time characteristics (opening and closing times, etc.), motion characteristics (opening and closing speeds, etc.), and mechanical characteristics (operating force, etc.). The circuit resistance of a switch is a key parameter characterizing the connection status of the conductive circuit; an abnormally high resistance can lead to excessive temperature rise at the contact points, causing equipment failure. The mechanical characteristics and circuit resistance of a switch are core indicators for evaluating equipment reliability and safety; therefore, mechanical characteristic and circuit resistance testing is required after switch production.

[0003] Currently, the mechanical characteristics and loop resistance of switches are usually tested separately using different testing equipment. Mechanical characteristics are usually tested using an online mechanical characteristic tester, while loop resistance is tested using a loop resistance tester. The testing procedures are complex, involve many steps, take a long time, and have low efficiency. Utility Model Content

The mounting plate 31 is provided with several positioning pins 35.

[0028] The clamping mechanism 4 is connected to the right support 14 of the frame 1 via mounting plate 41.

The guide shaft 46 is movably inserted into the guide sleeve 47.

[0029] The upper detection module 5 is connected to the upper support 12 of the frame 1 via the upper mounting base 51. For example... Figure 5 As shown, a lifting seat 52 is connected to the upper mounting base 51 of the upper detection module 5 via a lifting assembly. The lifting seat 52 is connected to a lifting cylinder 53, which can drive the lifting seat 52 to rise and fall. Several sets of upper ejection assemblies 54 are provided on the lifting seat 52. The upper ejection assembly 54 includes an upper ejection cylinder 541, an upper connecting seat 542, an upper ejection rod 543, and an upper contact 544. The cylinder seat of the upper ejection cylinder 541 is connected to the lifting seat 52. The upper connecting seat 542 is connected to the ejection part of the upper ejection cylinder 541. The upper ejection rod 543 is inserted into the upper connecting seat 542. The upper contact 544 is connected to the bottom end of the upper ejection rod 543. The upper ejection cylinder 541 pushes the upper ejection rod 543 and the upper contact 544 downward through the upper connecting seat 542.

[0030] The lower detection module 6 is connected to the base plate 21 of the base assembly 2 via the lower mounting bracket 61. For example...

The lower ejection component 62 includes a lower ejection cylinder 621, a lower connecting seat 622, a lower ejection rod 623, and a lower contact 624. The cylinder seat of the lower ejection cylinder 621 is connected to the base assembly 2. The lower connecting seat 622 is connected to the ejection part of the lower ejection cylinder 621. The lower ejection rod 623 is inserted into the lower connecting seat 622. The lower contact 624 is connected to the top of the lower ejection rod 623. The lower ejection cylinder 621 ejects the lower ejection rod 623 and the lower contact 624 upward through the lower connecting seat 622.

[0031] In actual use, the switch workpiece to be tested is placed on the left bracket 25 and right bracket 26 of the base assembly 2. The drive assembly 24 drives the carrier plate 22 to move toward the clamping assembly 3. After it moves into place, the clamping drive cylinder 33 of the clamping assembly 3 drives the clamping arm 32 to close and cooperate with the clamping block 34 to clamp the switch workpiece. The positioning pin 35 of the clamping assembly 3 is inserted into the corresponding positioning hole of the switch workpiece. After the switch workpiece is clamped, the pressing drive cylinder 43 of the pressing mechanism 4 pushes out the pressure plate 42, thus removing the switch workpiece. When the workpiece is clamped, the positioning pin 45 is inserted into the corresponding positioning hole of the switch workpiece; after clamping, the lifting cylinder 53 of the upper detection module 5 drives the lifting seat 52 to descend to the position and then stops. The upper ejection component 54 pushes the upper contact 544 downward, flat with the conductor plane of the switch workpiece and connects it; at the same time, the lower ejection component 62 of the lower detection module 6 pushes the lower contact 624 upward, flat with the conductor plane of the switch workpiece and connects it; after the upper detection module 5 and the lower detection module 6 are connected, mechanical characteristics and circuit resistance can be detected.

[0032] This invention allows for the simultaneous detection of mechanical properties and circuit resistance using a single device. The detection procedure is simple, saves detection steps, shortens detection time, and improves detection efficiency.

[0033] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
