Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a welding tooling for a hot plate of a water tank assembly. Background Technology

[0002] The primary function of a car's coolant reservoir (expansion tank) is to balance the pressure of the cooling system and replenish coolant when necessary. It prevents air bubbles from forming by venting gases within the cooling system, reducing coolant pressure and preventing damage to the water pump caused by cavitation. Furthermore, when the cooling system temperature rises, the expansion tank absorbs the expanding coolant, preventing excessive system pressure; it also replenishes coolant when the level drops. Coolant reservoirs used in fuel-efficient vehicles are typically made of reinforced PP / PE material and are often manufactured using hot-plate welding processes.

[0003] However, in the hot plate welding process of existing automotive water tank assemblies, the clamping fixture used to hold the water tank generally uses multiple pressure blocks to press and fix the water tank from the outside. This fixing method requires the use of multiple sensors to accurately control the clamping force and avoid deformation or even damage to the water tank, which leads to high tooling costs.

[0004] Therefore, it is necessary to provide a hot plate welding fixture for the water tank assembly to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a hot plate welding fixture for water tank assembly that can reduce damage to the water tank and has a lower cost.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0016] Example 1: like Figure 1-5 As shown, the hot plate welding fixture for the water tank assembly provided by this utility model includes: a fixed base 1, with an installation groove 2 on the top of the fixed base 1 that is adapted to the shape and size of the water tank. When welding, the water tank needs to be embedded into the installation groove 2, and the welding part of the hot plate needs to be exposed at a certain height. In order to fix the water tank in the installation groove 2, two adsorption fixing mechanisms are symmetrically arranged on the fixed base 1. The adsorption fixing mechanism includes multiple adsorption holes 3 opened on the fixed base 1. An exhaust pipe 4 connected to the adsorption holes 3 is installed on the side of the fixed base 1. An air pump 5 is installed on the exhaust pipe 4. In use, after the water tank is embedded in the installation groove 2, the air pump 5 is started to extract the air in the exhaust pipe 4, thereby creating a negative pressure in the adsorption holes 3, extracting the air between the inner wall of the installation groove 2 and the water tank, so that the outer wall of the water tank is adsorbed on the inner wall of the installation groove 2, and the water tank is effectively fixed. Then, the hot plate can be used to weld the water tank. The operation process and other required equipment are not described in detail here. After welding, the vacuum pump 5 stops, allowing the pressure inside the adsorption hole 3 to return to normal. The welded water tank assembly can then be removed from the mounting slot 2. This embodiment only improves the fixing fixture for the water tank and does not involve other equipment; therefore, there is no need to describe in detail the other necessary equipment for hot plate welding.

[0017] By setting a fixed base 1, an installation groove 2, and an adsorption fixing mechanism including an adsorption hole 3, an exhaust pipe 4, and an air pump 5, the air pump 5 is used to extract the air between the inner wall of the installation groove 2 and the water tank, so that the water tank is adsorbed on the inner wall of the installation groove 2 and fixed. Under this fixing method, the damage to the water tank is small, there is no need to precisely control the adsorption pressure, and the cost is lower.

[0018] Example 2: like Figure 1-3As shown, a clearance hole 6 is provided at the bottom of the mounting groove 2. The clearance hole 6 is designed to avoid the water outlet at the bottom of the water tank, making it easier for the water tank to be embedded into the mounting groove 2. An air inlet 7 is provided on one side of the clearance hole 6, which is connected to the exhaust port of the air pump 5. An electric control valve 8 is installed at the bottom of the clearance hole 6. A three-way valve 9 is installed between the air pump 5 and the exhaust pipe 4. One end of the three-way valve 9 is connected to the outside. In use, the electric control valve 8 is opened, and the handle on the three-way valve 9 is rotated, so that the air in the exhaust pipe 4 is drawn into the clearance hole 6 by the air pump 5. The gas is then discharged from the electric control valve 8, which fixes the water tank in the mounting slot 2. After welding, the electric valve 8 is closed, and the handle of the three-way valve 9 is rotated to connect the air pump 5 with the outside air. The exhaust pipe 4 is not connected to the air pump 5. The air pump 5 draws outside air into the clearance hole 6. As the electric control valve 8 is closed, the gas in the air gradually increases and enters the mounting slot 2, lifting the welded water tank assembly from the mounting slot 2, so that the outer wall of the water tank is separated from the inner wall of the mounting slot 2, making it easy to remove the water tank assembly from the mounting slot 2.

[0019] By providing clearance hole 6, air inlet 7, electric control valve 8 and three-way valve 9, the water tank assembly can be easily removed from the mounting slot 2.

[0020] Example 3: like Figure 2 As shown, in this embodiment, a rubber ring 10 is installed in the adsorption hole 3, and one side of the rubber ring 10 extends into the mounting groove 2 (about 0.5mm). After the water tank is embedded in the mounting groove 2, the rubber ring 10 fits against the surface of the water tank, improving airtightness and reducing the power consumption of the air pump 5.

[0021] By installing a rubber ring 10 inside the adsorption hole 3, the airtightness of the adsorption hole 3 can be improved, which can help reduce the power consumption of the air pump 5.

[0022] Example 4: like Figure 1-3 As shown, a clearance groove 11 is provided on the side of the mounting groove 2. The clearance groove 11 is used to avoid the return water pipe on the water tank, which facilitates the installation of the water tank.

[0023] By creating an clearance groove 11 on the side of the mounting groove 2, the installation of the water tank can be facilitated.

[0024] Example 5: like Figure 4-5As shown, in this embodiment, a boss 12 is provided on the rubber ring 10, with the top of the boss 12 serving as the contact surface. The boss 12 is installed facing the inner side of the mounting groove 2, and it is in contact with and fits against the outer wall of the water tank, thereby enhancing the airtightness between the adsorption hole 3 and the water tank. An annular groove 13 is provided inside the rubber ring 10, which makes the wall thickness of the boss 11 thinner and easier to deform. When squeezed by the water tank, it is easier to deform, reducing the pressure on the water tank and making it easier to remove the water tank assembly.

[0025] By providing a boss 12 on the rubber ring 10, the airtightness between the adsorption hole 3 and the water tank can be improved. By providing an annular groove 13 on the rubber ring 10, it is easier to remove the water tank assembly.

[0026] Working principle: During use, when welding the water tank, it needs to be embedded into the mounting groove 2. The hot plate welding part of the water tank is higher than the top of the mounting groove 2 by a certain height. The air pump 5 is started to extract the air from the exhaust pipe 4, thereby creating a negative pressure in the adsorption hole 3. This draws out the air between the inner wall of the mounting groove 2 and the water tank, causing the water tank to be adsorbed onto the inner wall of the mounting groove 2. The water tank is then effectively fixed, and the hot plate welding operation can begin. After welding is completed, the air pump 5 is stopped, allowing the pressure in the adsorption hole 3 to return to normal. Then, the welded water tank assembly can be removed from the mounting groove 2.
