[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] The radiator water chamber welding fixture of the present application mainly includes a base 1, a water inlet positioning block 2, and a clamp 3. Figure 1 As shown. The base 1 is welded from profiles, and a stopper 4, a positioning block mounting seat 20 and a clamp base 30 are directly mounted thereon. There are four stoppers 4, which are distributed in pairs. When the water chamber 7 is placed on the base 1, the four stoppers 4 are respectively attached to the left and top of the water chamber to limit the position of the left and top of the water chamber; the installation position of the positioning block mounting seat 20 is Figure 1 Figure 2 As can be seen in the figure, the specific position and angle of the radiator water chamber are determined according to the shape of the radiator water chamber. The top of the positioning block mounting seat 20 is provided with a circular through hole for mounting the water inlet positioning block 2. The installation relationship can be seen Figure 3 The nozzle positioning block 2 is used to locate the position of the nozzle to be welded; the clamp base 30 is used to install the clamp 3, and the clamp 3 can press and firmly fix the water chamber on the base 1 to prevent the water chamber from shifting during welding. Figure 3 As shown, it includes a sprue positioning platform 21 at the front end, a shaft 22 in the middle and a baffle 23 at the rear end. The sprue positioning platform 21 is stepped, and its contour is adapted to the sprue 6. It is used for positioning during sprue welding, and the front end is chamfered to prevent jamming and scratching; the middle shaft 22 is installed in the circular through hole of the positioning block mounting seat 20. Because the length of the shaft 22 is slightly larger than the length of the circular through hole, the shaft 22 can be allowed to move within a certain range along the axis in the circular through hole; the baffle 23 at the rear of the sprue positioning platform 21 is a detachable part and is installed in the circular through hole with the shaft 22. The baffle 23 is connected to the shaft 22 by bolts, and plays a positioning role when the sprue positioning platform 21 at the front end of the sprue positioning block 2 is inserted into the sprue 6.

[0014] When in use, the nozzle positioning block 2 is moved back, the clamp 3 is released, and the upper and lower workpieces are taken. Figure 4 As shown. Place the left and top sides of the water chamber 7 tightly against the stopper 4, and fix the water chamber with the clamp 3; extend the nozzle positioning block, insert the nozzle into the nozzle positioning platform 21 of the nozzle positioning block 2 and press it tightly, and then you can start the welding operation. After the welding operation is completed, return the nozzle positioning block 2, release the clamp 3, and then you can take out the workpiece from the bottom of the fixture.

[0015] The radiator water chamber welding fixture of the present application is very convenient to use, saves time and effort, can achieve the positioning requirements of radiator water chamber welding, reduce the labor intensity of operators, improve production efficiency, and save production costs.
