Description

Technical Field

[0001] This utility model belongs to the field of automotive radiator production equipment, and in particular relates to an automotive radiator core welding fixture. Background Technology

[0002] The automotive radiator is the core heat exchange component of the engine cooling system. Through the optimized combination of fluid channels and heat dissipation surfaces, it achieves rapid heat exchange between the coolant and the air (heat dissipation efficiency ≥85%), maintaining the engine operating temperature at 85-95℃.

[0003] Existing automotive radiators mainly consist of a core and inlet and outlet chambers located at the upper and lower ends of the core. The core includes end plates and heat dissipation pipes located between the end plates, with heat dissipation strips installed between the heat dissipation pipes. In existing technologies, after the core is assembled, it needs to be brazed. To ensure the stability of the core structure after assembly, steel wire ropes are generally used to bind the core together. Although this method can ensure the stability of the core structure before welding, it results in resource waste, as a large number of steel wire ropes need to be cut and discarded after brazing. Therefore, how to achieve reuse while ensuring the stability of the core structure is a problem that needs to be solved. Utility Model Content

[0004] This invention addresses the technical problems existing in the fixation of radiator cores before brazing, and proposes a reasonably designed, simple, easy-to-process, and reusable automotive radiator core welding fixture.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a welding fixture for an automotive radiator core, including a fixture box arranged in a cuboid shape and a drive gear rotatably arranged inside the fixture box. Lifting racks are fitted to both sides of the drive gear, and a connecting rod is connected to one end of each lifting rack. The connecting rods of the two lifting racks are arranged in opposite directions. The connecting rod passes through the fixture box, and a tension spring is fitted onto the connecting rod. The tension spring is arranged between the lifting rack and the fixture box. A clamping plate is provided at the end of the connecting rod away from the lifting rack, and the clamping plate is arranged at a perpendicular angle to the connecting rod.

[0006] Preferably, a handle is provided at the end of the clamp away from the connecting rod.

[0007] Preferably, the clamping plate is provided with clamping teeth.

[0008] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides a welding fixture for automotive radiator cores. By setting up a drive gear and a lifting rack, the synchronous movement of the clamping plates at both ends is achieved. With the help of a tension spring, the core is clamped and reused, thereby solving the technical problem of waste in the use of existing wire ropes. Attached Figure Description

Detailed Implementation

[0011] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0012] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0013] Example 1, such as Figure 1 , Figure 2As shown, this embodiment aims to solve the problem of waste caused by the existing brazing of steel wire binding of automobile radiator cores. To this end, in order to provide a recyclable device, the automobile radiator core welding fixture provided in this embodiment includes a fixture box 1 arranged in a cuboid shape and a drive gear 11 rotatably arranged in the fixture box 1. The width of the fixture box 1 is about 10cm, which is sufficient for a person to hold it with one hand. A rotating shaft 12 is fitted in the center of the drive rack. A hexagonal hole is provided in the rotating shaft 12. Holes are provided on the front and rear end faces of the fixture box 1. The rotating shaft 12 is fitted into the holes. Considering that its flexibility does not need to be too high, the rotating shaft 12 is not required. If stability is considered, a fixing tube can be provided on the front and rear end faces of the fixture box 1, and the rotating shaft 12 can be installed through the fixing tube.

[0014] Lifting racks 2 are fitted on both sides of the drive gear 11. A connecting rod 21 is connected to one end of each lifting rack 2. The connecting rods 21 of the two lifting racks 2 are positioned in opposite directions. Thus, when the rotating shaft 12 is rotated, the two connecting rods 21 can move towards or away from each other. Simultaneously, the connecting rod 21 passes through the clamping box 1, and a tension spring 4 is fitted onto the connecting rod 21. The tension spring 4 is positioned between the lifting racks 2 and the clamping box 1. A clamping plate 3 is located at the end of the connecting rod 21 away from the lifting racks 2, and the clamping plate 3 is positioned perpendicular to the connecting rod 21. Thus, when the two clamping plates 3 move away from each other, they compress the tension spring 4. Without external force, the tension spring 4 will return to its original position, causing the clamping plates 3 to move towards each other, thereby clamping the core.

[0015] In practical use, the worker places one end of the clamping plate 3 on one end of the assembled core, then pulls the other end so that the distance between the two clamping plates 3 is greater than the length of the core, and then clamps it. After welding is completed, the worker holds the fixture box 1 and uses an electric hex wrench inserted into the rotating shaft 12 to rotate it so that the clamping plates 3 move backward, and the fixture can be removed. In this way, the operation can be completed by one person.

[0016] To facilitate the pulling of the clamping plate 3, in this embodiment, a handle 31 is provided at the end of the clamping plate 3 away from the connecting rod 21.

[0017] To prevent the clamping plate 3 from being welded to the core (brazing involves spraying brazing fluid followed by high-temperature welding), clamping teeth 32 are provided on the clamping plate 3. These clamping teeth 32 reduce the contact area with the core, thus facilitating removal from the weld. Of course, the clamping box 1 is placed in a non-brazing position to avoid welding.

[0018] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
