[0021] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3The utility model provides a technical solution: an axial capacitor test fixture, comprising a base 1, two clamping mechanisms, a driving mechanism and a capacitor 2, the two clamping mechanisms are arranged opposite to each other, and both include a high support plate 4, a low support plate 5 and a bearing 6;

[0023] The low support plate 5 is connected to the high support plate 4 through the bearing 6 and is in a scissor shape with each other. The high support plate 4 and the low support plate 5 are combined into a port for testing the capacitor 2.

[0024] A limiting block 7 is arranged on the inner side of the high support plate 4 .

[0025] The driving mechanism includes a central shaft 8, two fixed blocks 9, a rotating block 10, three limit rods 11, two connecting plates 12, connecting bolts 13, and two springs 14;

[0026] The high support plate 4 is fixedly mounted on the base 1 by connecting bolts 13, and the two fixing blocks 9 are fixedly mounted on the bottom of the base 1, and a through hole is provided in the middle, and the central axis 8 is inserted into the through hole;

[0027] The rotating block 10 is fixedly mounted on the right end of the central shaft 8, and the two connecting plates 12 are fixedly connected to the two low supporting plates 5 respectively;

[0028] The bottoms of the two connecting plates 12 are both provided with through holes, and one ends of the two springs 14 are connected in the through holes, and the other ends of the two springs 14 are hung on the connecting bolts 13 .

[0029] Two grooves 3 are provided in the middle of the central shaft 8, and two connecting plates 12 are respectively fitted into the two grooves 3;

[0030] The operator places the capacitor 2 into the two clamping mechanisms so that the port 3 is located between the high support plate 4 and the low support plate 5, and supports the capacitor 2 through the limit block 7, thereby placing the capacitor 2;

[0031] Working principle:

[0032] When the clamp is in the open state: the external cylinder presses the rotating block 10 to rotate clockwise, thereby driving the central shaft 8 to rotate clockwise until the groove 3 fits with the connecting plate 12. At this time, the spring 14 generates a reaction force to pull the connecting plate 12 to fit with the groove 3, and the connecting plate 15 drives the lower support plate 5 to rotate clockwise through the bearing 6, thereby opening the clamp;

[0033] When the clamp is in the closed state: the external cylinder presses the rotating block 10 to rotate counterclockwise, so that it drives the central shaft 8 to rotate counterclockwise. At this time, the groove 3 of the central shaft 8 is out of contact with the connecting plate 12, and the outer surface of the central shaft 8 is pressed against the inner side of the connecting plate 12. The spring 14 is deformed by the force, and the connecting plate 12 drives the lower support plate 5 to rotate counterclockwise through the bearing 6, thereby closing the clamp and clamping the capacitor 2;

[0034] By setting up this axial capacitor test fixture, during use:

[0035] 1. When placing the capacitor 2, it first contacts the upper end of the low support plate 5 and is blocked by the high support plate 4, so that it slides between the high support plate 4 and the low support plate 5, which can prevent the capacitor 2 from entering the fixture and causing measurement errors due to inconsistent heights, and realize automation. The capacitor 2 can automatically slide between the high support plate 4 and the low support plate 5;

[0036] 2. The scissor-shaped high support plate 4 and low support plate 5 can improve the bearing capacity of the capacitor 2, prevent the port 3 from bending, and avoid affecting the test quality and test accuracy;

[0037] 3. By setting the limit block 7, the port 3 of the capacitor 2 can support the capacitor 2 after entering between the high support plate 4 and the low support plate 5 to prevent it from falling further and provide supporting capacity.
