The side plate has a connecting rod fixedly connected to its surface, and a first bearing is fixedly sleeved on its side. This utility model uses rotational adjustment to move the clamping plate and clamp the workpiece under the action of the threaded sleeve. However, during clamping, the clamping plate obstructs the contact area with the radiator core. These obstructed areas require adjustment of the clamping position of the radiator core during welding to expose them for welding, resulting in reduced welding efficiency. Therefore, to address these shortcomings, the inventor proposes this automotive radiator core welding fixture. Utility Model Content

[0004] The main purpose of this utility model is to provide a welding fixture for automotive radiator cores, which can effectively solve the problem in the prior art that the clamping position of the radiator core needs to be adjusted when welding obstructed positions.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] This utility model discloses a welding fixture for automotive radiator cores, such as... Figures 1-8 As shown, it includes a base 1, and the top surface of the base 1 is provided with pressure plates 2 on both the left and right sides for clamping the core of the car radiator.

[0026] The lower pressure plate 2 has multiple equally spaced movable slots 201 on one side. Each movable slot 201 has a rotating rod 204 fixedly installed inside it, and the outer surface of the rotating rod 204 is rotatably connected to a lower pressure claw 202. The lower pressure claw 202 can rotate around the rotating rod 204.

[0027] Both sides of the movable groove 201 are fixedly installed with torsion springs 205, and both torsion springs 205 are sleeved on the outer end of the rotating rod 204. Both torsion springs 205 are fixedly connected to the lower pressure claw 202. Through the elasticity of the torsion springs 205, the lower pressure claw 202 is in a vertical state under normal conditions.

[0028] Multiple limiting blocks 203 are provided on one side of the top surface of the pressure plate 2, and the multiple limiting blocks 203 correspond one-to-one with multiple movable slots 201.

[0029] A spring 2031 is fixedly installed on one side of the inner side of the limiting block 203, and a limiting rod 2032 is fixedly installed on one end of the spring 2031. When the limiting rod 2032 moves toward one side of the spring 2031, it will squeeze the spring 2031.

[0030] A portion of the limiting rod 2032 is located inside the limiting block 203, and another portion of the limiting rod 2032 is located outside the limiting block 203. A pull block 2034 is fixedly installed on one side of the outer top surface of the limiting rod 2032 inside the limiting block 203. A guide hole 2033 is provided in the middle of the outer top surface of the limiting block 203, and the pull block 2034 passes through the guide hole 2033 and extends to the outside of the limiting block 203. The user can hold the pull block 2034 and push the pull block 2034 to move it, which will drive the limiting rod 2032 to move.

[0031] A connecting block 2021 is fixedly installed on one side of the top surface of the pressing claw 202, and a connecting hole 2022 is opened on one side of the connecting block 2021. Before use, the user pulls the pull block 2034, which in turn drives the limiting rod 2032 to compress the spring 2031. Then, the pressing claw 202 is rotated to make it horizontal. Then, the pull block 2034 is released, and the compressed spring 2031 will push the limiting rod 2032 to reset, so that it is inserted into the connecting hole 2022 to prevent the pressing claw 202 from resetting due to the elasticity of the torsion spring 205. The above steps are repeated until all the pressing claws 202 are in a horizontal state.

[0032] Support plates 101 are fixedly installed on both the left and right sides of the top surface of the base 1, and two slide rods 102 are fixedly installed between the two support plates 101. Two clamping frames 103 are slidably connected to the outer surfaces of the two slide rods 102. The two clamping frames 103 can move along the two slide rods 102, so as to adjust the distance between the two clamping frames 103.

[0033] Moreover, the two lower pressure plates 2 are located inside the two clamping frames 103 respectively. When the two clamping frames 103 move, they will drive the two lower pressure plates 2 to move.

[0034] One side of each of the two support plates 101 is threaded with a first threaded rod 104. One end of each of the two first threaded rods 104 is rotatably connected to the two clamping frames 103, and the other end of each of the two first threaded rods 104 is fixedly mounted with a first rotating handle 105. The user holds and rotates the rotating handle to rotate the first threaded rod 104, and the rotation of the first threaded rod 104 will push the clamping frame 103 to move.

[0035] The outer top surfaces of both clamping frames 103 are threaded with second threaded rods 1032, and the bottom ends of the two second threaded rods 1032 are rotatably connected to the top surfaces of the two lower pressure plates 2 respectively. The top ends of the two second threaded rods 1032 are fixedly installed with second rotating handles 1033. The inner top surfaces of both clamping frames 103 are fixedly installed with two telescopic rods 1031, and the four telescopic rods 1031 are fixedly connected to the top surfaces of the two lower pressure plates 2 respectively. When the user holds and rotates the second rotating handles 1033, the second threaded rods 1032 will rotate, which will push the lower pressure plates 2 to rise and fall, and the telescopic rods 1031 will extend and retract with the rise and fall of the lower pressure plates 2.

[0036] After flipping the lower pressure claws 202 to a horizontal position, place the car radiator core to be welded into the two clamping frames 103. Then, rotate the two second threaded rods 1032 in sequence to push the two lower pressure plates 2 down until the multiple lower pressure claws 202 clamp and fix the car radiator core, and then welding can be carried out.

[0037] A vacuum cleaner 1041 is fixedly installed on the outer bottom surface of the base 1. The vacuum cleaner 1041 is powered by an external power source, and a suction pipe 1042 is fixedly installed at the inlet of the vacuum cleaner 1041. The suction pipe 1042 passes through the interior of the base 1 and extends to the outer top surface of the base 1. A suction head 1045 is fixedly installed at the end of the suction pipe 1042 away from the vacuum cleaner 1041. A storage tank 1044 is fixedly installed on one side of the outer bottom surface of the base 1, and a connecting pipe 1043 is fixedly connected between the outlet of the vacuum cleaner 1041 and the storage tank 1044.

[0038] When the motor of the vacuum cleaner 1041 is powered on, it runs at high speed, driving the fan blades to rotate and expelling air from the inside of the vacuum cleaner 1041 to the rear. The rotation of the fan causes the air inside the vacuum cleaner 1041 to be quickly expelled, reducing the internal pressure. The external air pressure is higher than the internal pressure, forming a negative pressure. This pressure difference causes the external air to carry the welding fumes through the suction head 1045 and be sucked in. The welding fumes enter the suction pipe 1042 through the suction head 1045 and then enter the storage tank 1044 through the connecting pipe 1043.

[0039] The working principle of this utility model is as follows: the user rotates the two first threaded rods 104 according to the size of the car radiator core to be welded, and pushes the two clamping frames 103 to move along the two sliding rods 102 to adjust the distance between the two clamping frames 103 until the car radiator core to be welded is placed in the two clamping frames 103.

[0040] The user then pulls the lever 2034, which in turn causes the limit rod 2032 to compress the spring 2031. Then, the user rotates the lower pressure claw 202 to make it horizontal. After that, the user releases the lever 2034, and the compressed spring 2031 pushes the limit rod 2032 to reset, so that it is inserted into the connection hole 2022 to prevent the lower pressure claw 202 from resetting due to the elasticity of the torsion spring 205. The above steps are repeated until all the lower pressure claws 202 are in a horizontal state.

[0041] The user holds and rotates the second handle 1033 to rotate the second threaded rod 1032, which will push the lower pressure plate 2 to rise and fall until the lower pressure claw 202 clamps and fixes the car radiator core placed in the clamping frame 103.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
