Description

Technical Field

[0001] This utility model relates to the field of capacitor fixing structure technology, specifically to a capacitor fixing link with adaptive clamping function. Background Technology

[0002] In existing technologies, when conducting capacitor charge and discharge tests, it is conventional to use a fixed bracket in advance to secure the capacitor to the test bench to ensure that the capacitor does not move or shake during the test, thereby affecting the accuracy and safety of the test.

[0003] Reference Figure 1 As shown, a conventional capacitor fixing bracket in the prior art includes a connecting rod 1, a cylinder 3 installed at one end of the connecting rod 1, and a clamp 2 fixed at the other end of the connecting rod 1. In use, the bracket is placed on the side of the test bench, and the capacitor is adjusted to the position corresponding to the clamp 2. Then, the cylinder 3 is activated, which causes the connecting rod 1 and the clamp 2 to move down as a whole until the clamp 2 is clamped on the capacitor from top to bottom, thus effectively fixing the capacitor.

[0004] However, the existing clamp 2 has a fixed size, which means it can only be used to fix a single type of capacitor. If there is a size deviation between the capacitor to be tested and the clamp 2, the clamp 2 needs to be replaced manually on the connecting rod 1. The operation is very time-consuming, labor-intensive and inefficient. Utility Model Content

[0005] To solve the above-mentioned technical problems, a capacitor fixing link with adaptive clamping function is provided. This solves the problem that the existing technology has a fixed clamp size, which makes it only usable for fixing a single type of capacitor. If there is a size deviation between the capacitor to be tested and the clamp, the clamp needs to be replaced manually on the link, which is very time-consuming, labor-intensive and inefficient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a capacitor fixing link with adaptive clamping function, including a link and a cylinder installed at one end of the link, and an adaptive clamping mechanism disposed at the other end of the link;

[0007] The adaptive clamping mechanism includes a pressure plate that is laterally fixed to the end of the connecting rod, two symmetrical clamping plates that slide elastically on the bottom surface of the pressure plate, and a pressure boosting part disposed on the connecting rod body. The bottom of the opposite side of the two clamping plates is sloping.

[0008] Preferably, two sliding heads are symmetrically fixed at the top of the clamping plate, and a sliding groove adapted to the sliding heads is opened on the bottom surface of the pressure plate. A return spring is fixed between the sliding head and the inner wall of one side of the sliding groove.

[0009] Preferably, the pressurizing part includes a horizontal plate that is slidably sleeved on the connecting rod body, and both sides of the inner wall of the middle part of the pressure plate are provided with clearance grooves. A pressure block in the shape of a right trapezoid and fixed to the bottom surface of the horizontal plate is slidably arranged in the clearance groove, and the top of the two clamping plates on the opposite side is arc-shaped.

[0010] Preferably, the connecting rod is fitted with an electromagnet that is fixedly connected to the top surface of the pressure plate, and the bottom surface of the cross plate is fixed with a magnetic block corresponding to the electromagnet.

[0011] Preferably, a connecting plate is provided above the horizontal plate and is fixedly connected to the connecting rod body, and a spring telescopic rod is fixed between the connecting plate and the horizontal plate.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] (1) By setting up an adaptive clamping mechanism, during the synchronous downward movement of the starting cylinder, the action link and the adaptive clamping mechanism, the inclined surfaces of the two clamping plates in the adaptive clamping mechanism can contact the two sides of the capacitor in advance and move away from each other under pressure, so as to quickly expand the distance between them according to the size of the capacitor, so that capacitors of different sizes and models can be clamped in the area between the pressure plate and the two clamping plates.

[0014] (2) By setting up the pressure boosting part, when the connecting rod moves down and the capacitor is clamped in the area between the pressure plate and the two clamping plates, the horizontal plate in the pressure boosting part moves down quickly and the pressure block passes through the inside of the clearance groove. In this way, the inclined side of the pressure block contacts the arc part of the clamping plate, forming a squeezing force on the clamping plate, thereby increasing the adhesion between the clamping plate and the capacitor and improving the clamping strength of the capacitor.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-4 As shown, a capacitor fixing link with adaptive clamping function includes a link 1, a cylinder 3 installed at one end of the link 1, and an adaptive clamping mechanism disposed at the other end of the link 1.

[0023] The adaptive clamping mechanism includes a pressure plate 4 that is laterally fixed to the end of the connecting rod 1 and two clamping plates 5 that are symmetrically and elastically slidable on the bottom surface of the pressure plate 4. The bottom of the opposite side of the two clamping plates 5 is sloping.

[0024] With the adaptive clamping mechanism, during the synchronous downward movement of the starting cylinder 3, the action link 1 and the adaptive clamping mechanism, the inclined surfaces of the two clamping plates 5 in the adaptive clamping mechanism can contact the two sides of the capacitor in advance, and move away from each other under pressure, so as to quickly expand the distance between them according to the size of the capacitor, so that capacitors of different sizes and models can be clamped in the area between the pressure plate 4 and the two clamping plates 5.

[0025] Furthermore, referring to Figure 4 As shown, it is worth noting that two sliding heads 6 are symmetrically fixed at the top of the clamping plate 5, and a sliding groove adapted to the sliding head 6 is opened on the bottom surface of the pressure plate 4. A return spring 7 is fixed between the sliding head 6 and the inner wall of one side of the sliding groove.

[0026] When the connecting rod 1 moves downward, the clamping plate 5 contacts the side of the capacitor and is squeezed to slide on the bottom surface of the pressure plate 4. The slide head 6 can move synchronously with the clamping plate 5 in the sliding gap and continuously compress the deformation of the return spring 7. In this way, the elastic force of the return spring 7 can be used to facilitate the upward movement of the connecting rod 1, so that the adaptive clamping mechanism can be disengaged from the capacitor. When the clamping plate 5 is no longer in contact with the capacitor, the slide head 6 and the clamping plate 5 can be quickly rebounded as a whole to reset the clamping plate 5 for secondary use. Alternatively, after the capacitor is clamped in the area between the pressure plate 4 and the two clamping plates 5, the elastic force can be used to push the slide head 6 back, so that the clamping plate 5 fits tightly with the capacitor, enhancing the lateral clamping effect of the capacitor.

[0027] Furthermore, referring to Figure 3 As shown, it is worth noting that the adaptive clamping mechanism also includes a pressure boosting part disposed on the body of the connecting rod 1 to enhance the contact strength between the clamping plate 5 and the capacitor;

[0028] The pressurizing part includes a horizontal plate 8 that slides on the body of the connecting rod 1. Both sides of the inner wall of the middle part of the pressure plate 4 are provided with clearance grooves 10. A pressure block 9 in the shape of a right trapezoid and fixed to the bottom surface of the horizontal plate 8 is slidably arranged in the clearance groove 10. The top of the two clamping plates 5 on the side away from each other is arc-shaped.

[0029] With the addition of the pressure boosting section, when the connecting rod 1 moves down and clamps the capacitor in the area between the pressure plate 4 and the two clamping plates 5, the horizontal plate 8 in the pressure boosting section moves down quickly and the pressure block 9 passes through the inside of the clearance groove 10 downward. In this way, the inclined edge of the pressure block 9 contacts the arc part of the clamping plate 5, forming a squeezing force on the clamping plate 5, thereby increasing the adhesion between the clamping plate 5 and the capacitor and improving the clamping strength of the capacitor.

[0030] Furthermore, referring to Figure 3 As shown, it is worth noting that the rod body of the connecting rod 1 is fitted with an electromagnet 14 that is fixed to the top surface of the pressure plate 4, and the bottom surface of the cross plate 8 is fixed with a magnetic block 13 corresponding to the electromagnet 14.

[0031] A connecting plate 11 is provided above the horizontal plate 8 and is fixedly connected to the body of the connecting rod 1. A spring telescopic rod 12 is fixed between the connecting plate 11 and the horizontal plate 8.

[0032] When the opening linkage 1 moves down, causing the capacitor to be stuck in the area between the pressure plate 4 and the two clamping plates 5, the electromagnet 14 is opened, so that a magnetic attraction force can be formed on the magnetic block 13, causing the horizontal plate 8 to quickly move down along the linkage 1 and pull down the spring telescopic rod 12.

[0033] After the capacitor test is completed, the electromagnet 14 is de-energized and turned off, so that the magnetic attraction between it and the magnetic block 13 disappears. Then, the horizontal plate 8 automatically moves up and resets under the elastic force of the spring telescopic rod 12, quickly relieving the squeezing force of the pressure block 9 on the clamping plate 5.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
