Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automotive radiator processing equipment, and in particular to an automotive radiator water inlet expansion and positioning structure. Background Technology
[0002] A car radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. Coolant flows inside the radiator core, while air passes outside. Hot coolant cools as it dissipates heat into the air, while the cool air warms up by absorbing the heat released by the coolant. The radiator is a critical component of the car's cooling system, and its nozzles must ensure no coolant leakage. Riveting technology uses mechanical means to tightly fix the radiator nozzles to the connecting components, forming a reliable seal. Current automotive radiator nozzle rivet positioning structures generally use clamps or other fixing equipment to fix the radiator in a designated position before riveting. However, because the position of the nozzles varies between different radiator models, and existing positioning structures are not convenient for fine-tuning the radiator according to the nozzle position, this affects subsequent riveting work. Utility Model Content
[0003] This invention provides a riveting and positioning structure for automotive radiator nozzles, which solves the problems in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A riveting and positioning structure for an automotive radiator water inlet includes a base, wherein a mounting plate for placing the radiator is rotatably connected to the top of the base.
[0006] A connecting rod is rotatably connected to one side of the base, and a worm gear is connected to one end of the connecting rod. A worm wheel is connected to the surface of the worm gear, and a rotating rod connected to the bottom end of the placement plate is connected to the surface of the worm wheel.
[0007] As a further description of the above technical solution:
[0008] The top of the placement plate has a groove, and a screw is rotatably connected inside the groove. The two sides of the screw are respectively threaded with movable blocks that are slidably connected to the inside of the groove, and the top of the movable blocks is connected with a fixed plate.
[0009] As a further description of the above technical solution:
[0010] The screw has threads on both sides that are reversed.
[0011] As a further description of the above technical solution:
[0012] One side of the base is connected to a mounting plate that is rotatably connected to a connecting rod, and the connecting rod passes through the mounting plate and is connected to a ratchet. The mounting plate is rotatably connected to two rotating tubes, and the surface of the rotating tubes is connected to a pawl that contacts the ratchet.
[0013] As a further description of the above technical solution:
[0014] The rotating tube is equipped with a torsion spring and a fixing rod inside.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0016] In this invention, the rotation of the connecting rod causes the worm at one end to rotate on the surface of the worm wheel, thereby causing the worm wheel to drive the rotating rod, the mounting plate, and the radiator to rotate. The position of the water inlet on the radiator can be finely adjusted to facilitate subsequent riveting work. At the same time, the connecting rod and worm can be limited by the cooperation of pawls and ratchet to prevent the mounting plate from causing the radiator to rotate during the riveting work.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-4 A riveting and positioning structure for automotive radiator water inlets includes a base 1. A mounting plate 2 for placing the radiator is rotatably connected to the top of the base 1. A connecting rod 3 is rotatably connected to one side of the base 1, and a worm gear 4 is connected to one end of the connecting rod 3. A worm wheel 5 is connected to the surface of the worm gear 4, and a rotating rod 6 connected to the bottom end of the mounting plate 2 is connected to the surface of the worm wheel 5. A rectangular groove is formed at the bottom of the base 1. The connecting rod 3, worm gear 4, and worm wheel 5 are all installed inside the rectangular groove. By rotating the connecting rod 3, the worm gear 4 connected to it can rotate on the surface of the worm wheel 5, thereby causing the worm wheel 5 to drive the rotating rod 6, the mounting plate 2, and the radiator to rotate. This allows for fine-tuning of the radiator, facilitating the riveting of the water inlets on the radiator.
[0025] Furthermore, a groove 7 is provided at the top of the placement plate 2, and a screw 8 is rotatably connected inside the groove 7. The two sides of the screw 8 are respectively threaded with movable blocks 9 that are slidably connected to the inside of the groove 7, and a fixed plate 10 is connected to the top of the movable blocks 9. By rotating the screw 8, the movable blocks 9 on its surface can drive the fixed plate 10 to move in a limited position. The radiator can be clamped and limited by the fixed plates 10 on both sides to facilitate subsequent riveting work.
[0026] Furthermore, the threads on both sides of the screw 8 are arranged in opposite directions, which is to facilitate the simultaneous movement of the moving blocks 9 on both sides of the screw 8 in opposite directions when the screw 8 rotates.
[0027] Furthermore, a mounting plate 11 is connected to one side of the base 1 and is rotatably connected to the connecting rod 3. The connecting rod 3 passes through the mounting plate 11 and is connected to a ratchet 12. Two rotating tubes 13 are rotatably connected inside the mounting plate 11, and pawls 14 that contact the ratchet 12 are connected to the surface of the rotating tubes 13. The two pawls 14 inside the mounting plate 11 are arranged in opposite directions. That is, one pawl 14 limits the ratchet 12 to rotate in the forward direction, while the other pawl 14 limits the ratchet 12 to rotate in the reverse direction. This can limit the connecting rod 3, etc. A knob is connected to the rotating tube 13 through the mounting plate 11. When the connecting rod 3 needs to rotate in a certain direction, the corresponding knob is rotated to remove the specified pawl 14 from the surface of the ratchet 12.
[0028] Furthermore, the rotating tube 13 is equipped with a torsion spring 15 and a fixing rod 16. The torsion spring 15, the fixing rod 16, and the rotating tube 13 facilitate the rotation and reset of the pawl 14.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
