Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of capacitor testing equipment, specifically to capacitor holders and capacitor testing devices. Background Technology
[0002] During the production process, capacitors need to undergo charge and discharge tests. In the traditional capacitor charge and discharge test process, the capacitor is usually fixed to a fixture manually first, and then the two electrodes of the capacitor are electrically connected to the test device. For example, a multimeter is commonly used to measure the capacitance by contacting the two probes of the multimeter with the two electrodes of the capacitor. This allows the operator to determine whether the capacitance is within the tolerance range. However, the existing fixtures clamp the capacitor in a rigid manner, which can easily damage the capacitor when the operator clamps it. Furthermore, after the capacitor is clamped, the two ends of the probes still need to be electrically connected to the capacitor, which is inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a capacitor holder and a capacitor testing device, thus solving the aforementioned technical problems.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a capacitor holder and a capacitor testing device, comprising a device body and a capacitor. The bottom of the device body has four support columns, and a limiting hole is formed on the device body. The capacitor is inserted into the limiting hole. A transmission cavity communicating with the limiting hole is formed inside the device body. A servo motor is installed in the transmission cavity, and a drive gear is installed on the output shaft of the servo motor. A rotating gear ring meshing with the drive gear is rotatably installed in the transmission cavity. Four arc-shaped guide grooves are formed along the circumferential direction on the top of the rotating gear ring. Sliding shafts are slidably installed in the arc-shaped guide grooves. Four guide grooves communicating with the outside are formed on the top inner wall of the transmission cavity. The four sliding shafts extend to the outside through the four guide grooves and are fitted with movable blocks. Threaded rods are threaded onto the movable blocks, and arc-shaped clamping blocks are rotatably installed on the threaded rods. The arc-shaped clamping blocks abut against the outer surface of the capacitor. A universal joint is connected to the device body.
[0007] Preferably, a lifting block is slidably installed inside the transmission cavity, the outer surface of the lifting block is provided with external threads, the rotating gear ring is provided with internal threads that are compatible with the external threads, and the test pen of the universal meter is connected to the lifting block.
[0008] Preferably, the transmission cavity is provided with a plurality of guide rods arranged at intervals along the circumferential direction, and the lifting block is slidably arranged on the plurality of guide rods.
[0009] Preferably, a limiting ring is arranged on the bottom inner wall of the transmission cavity, and the rotating gear ring is rotatably mounted on the limiting ring.
[0010] Preferably, each of the four guide grooves has a limiting groove on its inner wall, and each of the four slide shafts has a limiting slider that is adapted to the limiting groove.

[0012] Preferably, the end of the threaded rod away from the arc-shaped clamping block is provided with a rotating handle.
[0013] Compared with the prior art, this utility model provides a capacitor holder and a capacitor testing device, which has the following beneficial effects: This utility model, through the cooperation of a rotating gear ring, sliding shaft, movable block, and arc-shaped clamping block, allows the capacitor to be placed in the limiting hole during testing. At this time, the servo motor is activated to drive the drive gear to rotate, which in turn drives the rotating gear ring to rotate. Simultaneously, through the synchronous restriction of the arc-shaped guide groove and the guide slide groove, the movable blocks at the top of the four sliding shafts move closer to each other, causing the four arc-shaped clamping blocks to move closer to each other and press against the outer surface of the capacitor, thus fixing the capacitor. Furthermore, when the rotating gear ring rotates, the internal thread on the rotating gear ring cooperates with the external thread on the lifting block. Through the threaded advance, the lifting block rises vertically, causing the test pen on the universal joint connected to the lifting block to contact the capacitor. This eliminates the need for manual connection of the test pen to the capacitor's electrode head, further simplifying the testing process and improving work efficiency. Attached Figure Description

[0023] Please see Figure 1-5The capacitor 4 holder and capacitor 4 testing device include a device body 1 and a capacitor 4. Four support columns 2 are provided at the bottom of the device body 1. Limiting holes 9 are formed on the device body 1, and the capacitor 4 is inserted into the limiting holes 9. A transmission cavity 10 communicating with the limiting holes 9 is formed inside the device body 1. A servo motor 12 is installed in the transmission cavity 10. A drive gear 13 is installed on the output shaft of the servo motor 12. A rotating gear ring 11 meshing with the drive gear 13 is rotatably installed in the transmission cavity 10. Four arc-shaped guide grooves 14 are formed along the circumferential direction on the top of the rotating gear ring 11, and four arc-shaped guide grooves 14 are slidably installed within the arc-shaped guide grooves 14. There is a sliding shaft 18. The top inner wall of the transmission cavity 10 has four guide grooves 5 that communicate with the outside. The four sliding shafts 18 extend to the outside through the four guide grooves 5 and are equipped with movable blocks 6. The movable blocks 6 are threadedly connected to threaded rods 8. Arc-shaped clamping blocks 7 are rotatably installed on the threaded rods 8. The arc-shaped clamping blocks 7 are pressed against the outer surface of the capacitor 4. A universal gauge 3 is connected to the main body 1 of the device. A lifting block 16 is slidably installed in the transmission cavity 10. The outer surface of the lifting block 16 is provided with external threads. The rotating gear ring 11 is provided with internal threads 17 that are adapted to the external threads. The test pen 22 of the universal gauge 3 is connected to the lifting block 16.
[0024] By employing the coordinated structure of the rotating gear ring 11, sliding shaft 18, movable block 6, and arc-shaped clamping block 7, the capacitor 4 can be tested by first placing it in the limiting hole 9. Then, the servo motor 12 is activated to drive the drive gear 13 to rotate, which in turn drives the rotating gear ring 11 to rotate. Simultaneously, the arc-shaped guide groove 14 and the guide slide groove 5 synchronously restrict the movable blocks 6 at the top of the four sliding shafts 18 to move closer together, thereby causing the four arc-shaped clamping blocks 7 to move closer together and clamp against the outer surface of the capacitor 4, thus fixing the capacitor 4. Furthermore, when the rotating gear ring 11 rotates, the internal thread 17 on the rotating gear ring 11 engages with the external thread on the lifting block 16. Through the threaded engagement, the lifting block 16 rises vertically, causing the testing pen 22 on the universal joint 3 connected to the lifting block 16 to contact the capacitor 4. This eliminates the need for manual connection of the testing pen to the electrode head of the capacitor 4, further simplifying the testing process and improving work efficiency.
[0025] Specifically, in this embodiment, the transmission cavity 10 is provided with a plurality of guide rods 23 arranged at intervals along the circumferential direction, and the lifting block 16 is slidably arranged on the plurality of guide rods 23.
[0026] The guide rod 23 can restrict the movement direction of the lifting block 16 and make the movement of the lifting block 16 smoother.
[0027] Specifically, in this embodiment, a limiting ring 15 is arranged on the bottom inner wall of the transmission cavity 10, and the rotating gear ring 11 is rotatably mounted on the limiting ring 15.
[0028] The limiting ring 15 allows the rotating toothed ring 11 to rotate along the limiting ring 15, and restricts the position of the rotating toothed ring 11.
[0029] Specifically, in this embodiment, a limiting groove 19 is provided on the inner wall of each of the four guide grooves 5, and a limiting slider 24 adapted to the limiting groove 19 is provided on each of the four sliding shafts 18.

[0031] Specifically, in this embodiment, an installation block 20 is protruding on the arc-shaped clamping block 7, and a rotating block 21 is rotatably installed inside the installation block 20. The rotating block 21 is connected to the threaded rod 8.
[0032] By setting the rotating block 21, the threaded rod 8 can rotate within the rotating block 21.
[0033] Specifically, in this embodiment, a rotating handle is provided at the end of the threaded rod 8 away from the arc-shaped clamping block 7, which facilitates the operation of the threaded rod 8.
