[0019] As Figures 1-3 shown, the present utility model is a welding positioning device for radiator processing, including a support frame 1. It is characterized in that fixed plates 2 are provided on both sides above the support frame 1. A hydraulic cylinder 3 is provided on the side of the fixed plate 2 away from the support frame 1. The stroke end of the hydraulic cylinder 3 penetrates through the fixed plate 2 and is fixedly connected to the clamping plate 4. When the hydraulic cylinder 3 works, the hydraulic cylinder 3 pushes the clamping plate 4 to move in the horizontal direction. Through the mutual cooperation between the two clamping plates 4, the radiator can be stably clamped. At the same time, during the process of the clamping plate 4 clamping the radiator, the workpiece can be automatically aligned, thereby effectively ensuring the placement accuracy of the workpiece. Pushing components 5 are provided at both ends on one side of the support frame 1 where the fixed plate 2 is located. The pushing components 5 can push the radiator workpiece in the horizontal direction. Pressing-down components 6 are provided at both ends on the other side of the support frame 1 where the fixed plate 2 is located. The pressing-down components 6 can position the radiator workpiece.

[0020] The pushing component 5 includes a fixed block 51, a guiding groove 52, a push rod 53, a U-shaped connecting plate 54, a first connecting plate 55, a first grip rod 56 and a push plate 57.

[0021] The pressing-down component 6 includes a base 61, a second connecting plate 62, a connecting block 63, a through groove 64, a second grip 65, a pressing rod 66 and a pressing block 67.

[0022] The fixed block 51 is fixedly connected to the support frame 1. In the middle of the upper end of the fixed block 51, there is a guide groove 52. A push rod 53 is inserted in the middle of the guide groove 52. The push rod 53 can move horizontally inside the guide groove 52. One side of the push rod 53 away from the support frame 1 is movably connected to a U-shaped connecting plate 54 through a pin shaft. The outer side of the U-shaped connecting plate 54 is movably connected to a first connecting plate 55 through a pin shaft. The first connecting plate 55 is movably connected to the fixed block 51 through a pin shaft. One side of the U-shaped connecting plate 54 away from the fixed block 51 is provided with a first grip 56. One side of the push rod 53 away from the U-shaped connecting plate 54 is fixedly connected to a push plate 57. When the first grip 56 is pushed, the first grip 56 drives the U-shaped connecting plate 54 to rotate. The U-shaped connecting plate 54 pushes the push rod 53, and at the same time, the first connecting plate 55 rotates around the fixed block 51. Through the mutual cooperation between the first connecting plate 55 and the U-shaped connecting plate 54, the push plate 57 can push the radiator workpiece to move horizontally.

[0023] The base 61 is fixedly connected to the support frame 1. On both sides above the base 61, there are second connecting plates 62 through pin shafts. The upper ends of the second connecting plates 62 are movably connected to a second grip 65 through pin shafts. One side of the base 61 away from the support frame 1 is movably connected to a connecting block 63 through a pin shaft. There is a through groove 64 below the second grip 65. The upper ends of the second connecting plates 62 are movably connected to the connecting block 63 through pin shafts. One side of the connecting block 63 away from the base 61 penetrates through the through groove 64 and is fixedly connected to a pressing rod 66. The lower part of the pressing rod 66 is fixedly connected to a pressing block 67. When the second grip 65 is pushed, the second grip 65 drives the connecting block 63 and the second connecting plates 62 to move, so that the connecting block 63 and the second connecting plates 62 both rotate around the base 61. Through the mutual cooperation between the connecting block 63 and the second connecting plates 62, the pressing rod 66 drives the pressing block 67 to squeeze the radiator workpiece. Furthermore, through the mutual cooperation between the pressing block 67 and the support frame 1, the lower pressing assembly 6 can stably clamp the radiator workpiece.

[0024] There is a rubber pad 68 below the pressing block 67. The rubber pad 68 can protect the contact surface between the pressing block 67 and the radiator workpiece.

[0025] On both sides of the hydraulic cylinder 3 where the fixed plate 2 is located, there are guide rods 7. The guide rods 7 are fixedly connected to the clamping plates 4. The guide rods 7 are movably connected to the fixed plate 2. Through the mutual cooperation between the guide rods 7 and the fixed plate 2, the moving stability of the clamping plates 4 is effectively improved.

[0026] On both sides of the support frame 1, there are mounting plates 8. There are a plurality of equally spaced mounting holes 9 on the mounting plates 8. The positioning device can be fixedly installed through the mounting holes 9 on the mounting plates 8.

[0027] Specifically, in the present utility model, when welding the radiator, the second grip 65 is pushed. The second grip 65 drives the connecting block 63 and the second connecting plate 62 to move, so that the connecting block 63 and the second connecting plate 62 both rotate around the base 61. Through the mutual cooperation between the connecting block 63 and the second connecting plate 62, the pressure rod 66 drives the pressure block 67 to extrude the radiator workpiece. Furthermore, through the mutual cooperation between the pressure block 67 and the support frame 1, the lower pressing assembly 6 can stably clamp the radiator workpiece. After that, the first grip rod 56 is pushed. The first grip rod 56 drives the U-shaped connecting plate 54 to rotate. The U-shaped connecting plate 54 pushes the push rod 53, and at the same time makes the first connecting plate 55 rotate around the fixed block 51. Through the mutual cooperation between the first connecting plate 55 and the U-shaped connecting plate 54, the push plate 57 pushes another radiator workpiece to move towards the side of the fixed radiator workpiece. Secondly, the hydraulic cylinder 3 pushes the clamping plate 4 to move in the horizontal direction. Through the mutual cooperation between the two clamping plates 4, the radiator can be stably clamped. At the same time, during the process of the clamping plate 4 clamping the radiator, the workpieces can be automatically aligned.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
