Description

Technical Field

[0001] The utility model relates to the technical field of testing lifting mechanisms, in particular to a power capacitor testing lifting mechanism with a stable structure. Background Art

[0002] Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. Two conductors close to each other with a layer of non-conductive insulating medium in between constitute a capacitor. When voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of the capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates.

[0003] However, when inspecting capacitors, a test sorting machine is required for test sorting. However, the contact relationship between the brush in the current test machine and the capacitor test fixture is sliding friction, which will make the distance between the brush and the test fixture electrode fixed, thereby increasing the wear between the brush and the test fixture electrode, easily causing damage, which will affect the normal use of the test sorting machine. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a power capacitor test lifting mechanism with a stable structure, which overcomes the deficiencies of the prior art and effectively solves the problem in the prior art that the distance between the brush and the test fixture electrode is fixed, thereby increasing the wear between the brush and the test fixture electrode and easily causing damage.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A power capacitor test lifting mechanism with a stable structure comprises a driving assembly and a lifting assembly, wherein the driving assembly comprises a base plate, support tubes fixed at both ends of the top of the base plate, a support rod plugged and movable at the top of the support tube, a support plate fixed at the top of the base plate, a rotating shaft rotatably connected to the top of the support plate, and an elliptical block fixed to one end of the rotating shaft; and the lifting assembly comprises a fixed plate, a fixed frame fixed to the bottom of the fixed plate, a roller rotatably connected to the bottom end of the fixed frame, a connecting plate equidistantly plugged into the outer wall of one side of the fixed plate, a connecting rod fixed to one end of the bottom of the connecting plate, and an electric brush fixed to the bottom end of the connecting rod.

[0007] The servo motor drives the rotating shaft to rotate, which in turn drives the elliptical block to rotate. Along the rotation trajectory of the elliptical block, the support rod is inserted and slid along the support tube, and the roller and the elliptical block are rolled together, so that the roller moves up and down along the rotating outer wall of the elliptical block, so that the entire lifting assembly is regularly and continuously displaced up and down, so that the electric brush can move up and down against the capacitor below.

[0008] Preferably, a servo motor is installed at the top end of the back of the support plate, and the output shaft of the servo motor is connected and fixed to the rotating shaft.

[0009] The servo motor drives the rotating shaft to rotate, thereby driving the elliptical block to rotate.

[0010] Preferably, the top end of the support rod is connected and fixed to the bottom end of the fixing plate.

[0011] The driving assembly and the lifting assembly are connected via a support rod.

[0012] Preferably, the roller forms a rolling fit with the elliptical block.

[0013] The rotating elliptical block moves the roller up and down.

[0014] Preferably, an outer wall on one side of the fixing plate is provided with openings distributed at equal distances, and the openings are plug-fitted with the connecting plate.

[0015] The connecting plate is plugged into the fixing plate through the opening.

[0018] The beneficial effects of the utility model are:

[0019] The servo motor drives the rotating shaft to rotate, which in turn drives the elliptical block to rotate. Along the rotation trajectory of the elliptical block, the support rod cooperates with the insertion and sliding along the support tube, and the rolling cooperation between the roller and the elliptical block causes the roller to move up and down along the rotating outer wall of the elliptical block, so that the entire lifting assembly is regularly and continuously displaced up and down, so that the electric brush can move up and down and abut against the capacitor below, effectively solving the problem in the prior art that the distance between the brush and the test fixture electrode is fixed, thereby increasing the wear between the brush and the test fixture electrode and easily causing damage.
