Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor vibration testing technology, and specifically to a capacitor vibration testing clamping device. Background Technology
[0002] During the processing of capacitors, they need to be installed and positioned, which is usually assisted by specialized jigs. Patent No. CN212240702U discloses a fixture suitable for capacitor vibration testing. It uses a fixing frame and a limiting frame to clamp and fix the capacitor. Then, the fixing frame is installed on the frame through the first fixing hole, and then the fixing frame is installed on the frame through the second fixing hole. This allows the capacitor to switch quickly in different vibration directions, improving the efficiency of capacitor vibration testing. However, when switching directions, it is necessary to remove the fixing pin and rotate it to re-fix the position of the limiting frame, which reduces the testing efficiency.
[0003] Specifically, existing capacitor vibration test clamping devices are insufficient in terms of flexibility and rapid switching. Therefore, there is an urgent need for a new type of capacitor vibration test clamping device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a capacitor vibration test clamping device to solve the problems mentioned above.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A capacitor vibration test clamping device includes: a mounting frame, a half shaft, and a half-limiting mold. The half-limiting mold has half shafts fixed at both ends. The half-limiting mold and the half shafts are symmetrically fitted together. The half shaft has a mounting groove on its arc-shaped side. The mounting frame is provided on the outer side of the half shaft. The mounting frame and the mounting groove are perforated with splines at corresponding positions.
[0007] The mounting bracket has a U-shaped side, and the half-shaft is placed in the middle of the mounting bracket.
[0008] Multiple mounting slots are equidistantly distributed on the arc-shaped side of the half-shaft, and a connecting block is fixed to one end of the spline.
[0009] By rotating the half-shaft to adjust the spline mounting slot, the angle of the capacitor clamped by the half-limiting mold can be changed. The vibration table installed at the bottom conducts vibration tests on the clamped capacitor through the mounting bracket, thereby realizing the rapid switching of the capacitor to different vibration directions.
[0010] The mounting bracket has symmetrical fixed feet on both sides of its bottom, and the fixed feet have mounting holes in the middle, which are fixedly connected to the vibration table by external fixing pins.
[0011] By symmetrically installing fixing feet on both sides of the mounting bracket, it is ensured that the half-shafts on both sides are synchronously subjected to consistent vibration transmission, so that the capacitor is subjected to uniform force during the clamping test.
[0012] The semi-limiting mold has multiple limiting holes for clamping the capacitor for vibration testing.
[0013] The limiting hole is fitted with a limiting sleeve, and the two ends of the limiting sleeve are fitted with fixing rings.
[0014] Two limiting sleeves are installed on both sides of the limiting hole. After the limiting sleeves fit and clamp the capacitor, the fixing ring is put on both ends of the limiting sleeves to prevent the limiting sleeves from sliding out of the limiting hole and avoid damage when the limiting hole abuts the capacitor due to vibration.
[0015] The shape of the limiting hole is adapted to the capacitor, and different capacitors can be clamped by changing the half limiting mold.
[0016] The beneficial effects of this utility model are:
[0017] 1. In the vibration test of a capacitor, when changing the capacitor's direction, the mounting bracket does not need to be disassembled and reinstalled. Simply pull up the spline connecting block, rotate the half-shaft, and re-fit it into the remaining mounting slots to flexibly adjust the clamping angle, meeting the vibration test requirements in different directions. This simplifies the preparation work for multi-directional vibration testing and improves test efficiency. The fixed feet at the bottom of the mounting bracket ensure uniform transmission of the vibration source, avoiding uneven force on the capacitor caused by asymmetrical vibration, and ensuring the accuracy of the test results.
[0018] 2. This utility model, through the design of the limiting holes and the matching limiting sleeves and fixing rings on the semi-limiting mold, not only ensures the stable clamping of the capacitor during the test and effectively prevents slippage or displacement during vibration, but also avoids additional physical damage to the capacitor during the clamping process by matching different limiting hole sizes and shapes with different capacitors, thus ensuring the safety of the test.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1 and Figure 2 As shown, a capacitor vibration test clamping device includes: a mounting frame 1, a half shaft 3 and a half limiting mold 4. The half limiting mold 4 is fixed with half shafts 3 at both ends. The half limiting mold 4 and the half shafts 3 are symmetrically fitted together. The arc-shaped side of the half shaft 3 is provided with a mounting groove 7. The mounting frame 1 is provided on the outside of the half shaft 3. The mounting frame 1 and the mounting groove 7 are perforated and installed with splines 2 at corresponding positions.
[0029] The side of the mounting bracket 1 is U-shaped, and the half-shaft 3 is placed in the middle of the mounting bracket 1.
[0030] Please see Figure 3 and Figure 4 As shown, multiple mounting slots 7 are equidistantly distributed on the arc-shaped side of the half-shaft 3, and a connecting block 201 is fixed to one end of the spline 2.
[0031] Figure 1 and Figure 2 This is a schematic diagram of the clamping device of this utility model, showing the vertical and horizontal clamping states of the capacitor. The installation slot 7 of the spline 2 is switched by rotating the half shaft 3. After changing the angle of the capacitor clamped by the half limit mold 4, the vibration table installed at the bottom conducts a vibration test on the clamped capacitor through the mounting frame 1, thereby realizing the rapid switching of the capacitor to different vibration directions.
[0032] Mounting bracket 1 has symmetrical fixed feet 101 on both sides of the bottom. The fixed feet 101 have mounting holes in the middle and are fixedly connected to the vibration table by external fixing pins.
[0033] By symmetrically installing fixing feet 101 on both sides of the mounting bracket 1, it is ensured that the half shafts 3 on both sides are synchronously subjected to consistent vibration transmission, so that the capacitor is subjected to uniform force during the clamping test.
[0034] Please see Figures 5-6 As shown, the semi-limiting mold 4 has multiple limiting holes 5 for clamping the capacitor for vibration testing.
[0035] Figures 5-6 This is a schematic diagram of the limiting sleeve 6 that clamps a cylindrical capacitor and a rectangular capacitor respectively. The limiting hole 5 is used to hold the limiting sleeve 6, and the two ends of the limiting sleeve 6 are fitted with fixing rings 601.
[0036] The upper and lower limit sleeves 6 are respectively installed on both sides of the limit hole 5. After the limit sleeves 6 fit and clamp the capacitor, the fixing rings 601 are put on both ends of the limit sleeves 6 to prevent the limit sleeves 6 from sliding out of the limit hole 5 and avoid damage caused by vibration when the limit hole 5 abuts against the capacitor.
[0037] The shape of the limiting hole 5 is adapted to the capacitor, and different capacitors can be clamped by changing different half-limiting molds 4.
[0038] The working principle of this utility model is as follows: the mounting brackets 1 on both sides are installed on the vibration table, the half shafts 3 at both ends of the half limiting mold 4 with the capacitor installed are placed in the slots of the mounting bracket 1, and the spline 2 is inserted to fix the half shafts 3.
[0039] After attaching the appropriate limiting sleeve 6 to clamp the capacitor, place it in the limiting hole 5. Then, put the fixing ring 601 on both ends of the limiting sleeve 6 to prevent the limiting sleeve 6 from slipping out of the limiting hole 5 and to avoid damage when the limiting hole 5 contacts the capacitor during vibration. Start the vibration test.
[0040] Switch the capacitor direction to continue the vibration test. Mounting bracket 1 does not need to be disassembled and reinstalled. Pull up the connecting block 201 of spline 2, rotate half shaft 3 to re-fit into the remaining mounting slots 7, and adjust the clamping angle to meet the vibration test requirements in different directions.
