Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tooling technology in the manufacturing process of electronic instrument transformers, and specifically relates to a sensor resin tank sealing device. Background Technology

[0002] In the manufacturing process of H-type capacitive sensor series electronic instrument transformers, the resin tank lid and body need to be glued together. The traditional method involves workers evenly applying sealant to the outer edges of both the lid and body, then pressing the lid firmly onto the tank to ensure a tight seal. If necessary, a weight is placed on the tank to prevent leakage after the inflation process. However, due to insufficient manual pressing and high internal pressure, leaks frequently occur during subsequent leak testing, significantly reducing product yield, increasing manufacturing costs, and impacting delivery time. Summary of the Invention

[0003] The technical problem solved by this utility model is to provide a sealing device for sensor resin tanks. This device can directly apply pressure to the resin tank body for a long time, ensuring a tight seal between the resin tank lid and the resin tank body until the sealant cures and the bonding is complete. This device is made of molybdenum-containing stainless steel, which is high-temperature resistant and corrosion-resistant, increasing its service life. It can simultaneously press multiple resin tanks, with adjustable pressure, improving production efficiency and product qualification rate.

[0005] Preferably, the positioning box is made of rubber and has elastic deformation capability to adapt to resin tanks of different sizes.

[0006] Preferably, the rubber sleeve covers the bottom end of the loading module to reduce frictional damage during pressurization.

[0007] Preferably, the compression of the spring is adjusted by the depth of screwing in the bolt.

[0008] Preferably, the spring is a replaceable component, and the range of elastic potential energy can be adjusted by replacing springs of different specifications.

[0009] Preferably, the base, support frame, and crossbeam are made of molybdenum-containing stainless steel, which is resistant to high temperatures and corrosion.

[0010] Preferably, the number of through holes is the same as the number of positioning boxes, and there are more than 2 sets.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a sensor resin tank sealing device with good stability, strong practicality, and excellent adaptability to vertical pressure loading. By setting a positioning box, the resin tank can be fixed in place, ensuring uniform force distribution; by setting a rubber sleeve, stress friction can be reduced, preventing scratches and damage to the resin tank lid; by setting a spring, the applied external force is converted into elastic potential energy; and by setting a locking device, stable application and release of external force can be achieved.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] This utility model relates to a sealing device for a sensor resin tank. See [link / reference]. Figures 1 to 3As shown, the device includes a base 1, with support frames 2 at both ends. A crossbeam 3 is mounted on the upper side of the support frames 2. The base 1, support frames 2, and crossbeam 3 form a rectangular frame. A through hole 4 is provided on the crossbeam 3 for installing a locking and pressure-applying device. A positioning box 5 is provided on the base 1 corresponding to the through hole 4. The positioning box 5 is made of rubber, which has high flexibility and elasticity, and is durable. The lower end of the locking and pressure-applying device is a loading module 6, which is used for contact pressure application to the resin tank 14. A rubber sleeve 7 is fitted at the bottom of the loading module 6. The rubber sleeve 7 has good elasticity and can reduce scratches caused by external friction between the loading module 6 and the resin tank 15, thus reducing the impact on the appearance of the resin tank 15. A bolt hole 8 is provided in the middle of the loading module 6, which is used to connect a bolt 9 and also for adjusting the applied force. A tension handle 10 is welded to the uppermost end of the bolt 9, and a positioning pin 11 is provided below the tension handle 10. Fixed posts 12 are provided at the upper and lower ends of 4. The upper end of the fixed post 12 is provided with a horizontal opening to lock the positioning pin 11 on the bolt 9. The bolt 9 is inserted into the through hole 4 and passes through the crossbeam 3. The positioning pin 11 is locked in the horizontal opening of the fixed post 12. The bolt 9 below the crossbeam 3 is sequentially equipped with spring 13, nut 14 and spring 13. The diameter of spring 13 is slightly smaller than the diameter of fixed post 12, so that spring 13 is completely pressed against the end face of fixed post 12. The end of bolt 9 is tightened to the loading module 6 to form a complete locking and pressure device.

[0018] In actual use, the sensor resin tank sealing device is placed on a horizontal operating table. Resin glue is evenly applied to the outer edge of the resin tank lid and the resin tank body and then bonded together. The tension handle 10 is manually pulled open, the spring 13 contracts, generating elastic potential energy. The bonded sensor resin tank is placed in the positioning box 5. The tension handle 10 is released, the spring 13 extends, and the elastic potential energy is released. Under the action of the spring 13, the loading module 6, which is covered by the rubber sleeve 7, generates a vertical constant pressure, which is directly applied to the lid of the resin tank 15. If the applied pressure is not appropriate, the depth of the bolt 9 in the bolt hole 8 can be adjusted to change the magnitude of the vertical constant pressure. The spring specification can be changed according to actual needs to achieve a greater conversion of elastic potential energy.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
