Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding positioning devices, and in particular to a welding positioning fixture for a radiator bracket. Background Technology
[0002] The main body of the aluminum alloy radiator consists of a radiator core, an upper water storage chamber, a lower water storage chamber, a left support, and a right support. The assembly and welding sequence is as follows: 1) Weld the upper water storage chamber and the lower water storage chamber to the openings on the upper and lower sides of the radiator core; 2) Weld the left support and the right support to the left and right sides of the radiator core.
[0003] After the radiator core is welded and assembled with the upper and lower water storage chambers, the side supports are then welded. In the existing technology, the radiator core is usually placed flat on the welding platform, and then the left and right side supports are arranged neatly and weighted to hold them in place before welding. However, this operation is cumbersome and the positioning is not accurate, which can easily lead to loosening during the welding process and affect the welding work. In particular, after the top part is welded, the entire radiator needs to be manually flipped over to weld the other side. This operation requires manual intervention, which increases the complexity of the operation and greatly reduces efficiency. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a radiator bracket welding positioning fixture, which solves the problems of unstable positioning of the welding platform for the support rod radiator core and water storage chamber in the existing technology, and the need for manual flipping after welding.
[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:
[0006] A radiator bracket welding positioning fixture includes a support frame. The upper ends of the two side plates of the support frame are rotatably connected to a main support frame via a rotating shaft. The main support frame has openings on both sides along the axial direction of the rotating shaft. Two side support frames are fixed on the outer wall of the main support frame at positions opposite to the two openings. The side support frames are open on the side and top of the main support frame and form a welding operation space with the main support frame.
[0007] The outer side of the main support frame is provided with a positioning component, which is used to limit the radiator core, water storage chamber and left and right side supports within the main support frame and side support frame. The rotating shaft is driven to rotate by the flipping component.
[0008] Preferably, the positioning component includes guide rod cylinders symmetrically fixed on the outer walls of the main support frame on both sides perpendicular to the axis of rotation. The two guide rod cylinders are arranged opposite each other, and the extended ends of the guide rod cylinders are fixed with rubber pads to ensure clamping while reducing damage to the outer wall of the water storage chamber.
[0009] Preferably, the flipping assembly includes a motor fixed to the lower end of one side plate of the support frame, an active synchronous pulley fixed to the output end of the motor, a driven synchronous pulley fixed to the end of a rotating shaft near the motor, and a synchronous belt connecting the active and driven synchronous pulleys. The motor is a worm gear reducer motor.
[0010] Preferably, a receiving groove is fixed between the two side plates of the support frame at the lower section. The receiving groove is arranged at an angle and is located directly above the motor. When the main support frame is flipped, the receiving groove can collect the falling welding slag, preventing the welding slag from falling to the ground and affecting the working environment, and eliminating the need for manual cleaning.
[0011] Compared with the prior art, the advantages of this utility model are as follows:
[0012] 1. This utility model can stably constrain the radiator core and the bracket through the design of the main support frame and the side support frame, ensuring welding accuracy. Through the setting of structures such as motor, rotating shaft and synchronous belt, the main support frame can achieve an automated flipping effect. Thus, during the welding process, there is no need to manually flip the radiator core. It can be ensured that the upper and lower parts of the contact position between the radiator core and the bracket can be directly completed after one clamping. Moreover, there is no need to unclamp and re-clamp after flipping. This further saves manpower, reduces operation steps and improves work efficiency.
[0013] 2. This utility model, through the setting of the receiving groove and the design of the automatic flipping of the main bearing frame, enables the welding slag generated during the welding process to be collected, preventing the welding slag from falling to the ground, thus eliminating the need for manual cleaning of the ground, further saving manpower, and greatly improving the ease of use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1, please refer to Figures 1 to 3 This embodiment provides a radiator bracket welding positioning fixture, which includes a support frame 1. The upper ends of the two side plates of the support frame 1 are rotatably connected to rotating shafts 2 via bearings. A main bearing frame 3 is fixed to one end of the two rotating shafts 2 that are close to each other. Openings 301 communicating with the inner cavity of the main bearing frame 3 are formed on two longitudinal side walls in a first direction, which is the same as the axial direction of the rotating shafts 2. Two opposing side bearing frames 4 are fixed to the outer wall of the main bearing frame 3 at positions opposite the two openings 301 via connectors. The two side support frames 4 are open on the side and top of each other, and there is a certain distance between the side support frame 4 and the main support frame 3. When welding and positioning, the radiator core after the water storage chamber is fixed is first inserted into the main support frame 3. Both sides of the side support to be welded on the radiator core are in the opening 301. The opening 301 and the distance are set so that after the left support and right support are inserted into the side support frame 4, the welding position of the side support frame 4 and the main support frame 3 is exposed, which facilitates the welding operation.
[0021] The main support frame 3 has two corresponding connecting plates 5 fixed on its two longitudinal side walls in the second direction. The second direction is perpendicular to the first direction. A guide rod cylinder 6 is fixed on the top surface of the connecting plate 5. The two guide rod cylinders 6 are arranged opposite each other. A rubber pad 601 is fixed to the extended end of the guide rod cylinder 6. After the radiator core, left support and right support of the water storage chamber are welded and installed, the welding equipment is operated manually on the top surface or by automated welding equipment to weld the upper part of the contact position between the left and right supports and the radiator core. After welding, the main support frame 3 needs to be flipped so that the lower part of the contact position can be welded. Before flipping, the two guide rod cylinders 6 are driven to extend simultaneously so that the rubber pad 601 abuts against the outer wall of the water storage chamber on both sides, thereby limiting the left and right supports and the radiator core within the main support frame 3 and the side support frame 4 to ensure that they do not fall off after flipping.
[0022] The main support frame 3 is driven to rotate by a motor 7 fixed to the inner side of the lower end of one side plate of the support frame 1. The extended end of the motor 7 extends through the side plate of the support frame 1 to the outer side of the support frame 1 and is fixed with a driving synchronous pulley 8. A driven synchronous pulley 9 is fixed to the end of a rotating shaft 2 near the motor 7. A synchronous belt 10 is connected between the driving synchronous pulley 8 and the driven synchronous pulley 9. By driving the motor 7 to rotate, the rotating shaft 2 and the main support frame 3 can be rotated. Then, the lower part of the contact position between the radiator core and the left and right side brackets can be welded. It should be emphasized that the motor 7 is a worm gear reducer motor 7, or other type with... The motor 7 has a power-off self-locking effect to ensure that the main support frame 3 will not rotate arbitrarily after the motor 7 stops rotating, thus ensuring stability. After the lower part of the contact position is also welded, the drive motor 7 causes the main support frame 3 to rotate in the opposite direction to reset. Then, the extended ends of the two guide rod cylinders 6 retract, and the entire radiator core can be directly taken out upward. It should be further explained that since the two guide rod cylinders 6 are located on the same side of the main support frame 3, each time the motor 7 drives the main support frame 3 to flip, it ensures that the rotation direction is such that the guide rod cylinders 6 flip upward around the rotating shaft 2. This ensures that the main support frame 3 can rotate while the guide rod cylinders 6 do not conflict with the side plate of the support frame 1.
[0023] Throughout the welding process, the heat sink core and bracket can be stably constrained to ensure welding accuracy. Because it can automatically flip, there is no need for manual flipping, which saves manpower and improves work efficiency. Moreover, the main support frame 3 can be flipped directly without the need to remove the clamps of the heat sink core and then flip it over to re-clamp it. Compared with traditional technology, this reduces the number of operation steps and improves work efficiency.
[0024] Example 2, please refer to Figure 4 This embodiment provides a further technical solution based on embodiment one. A receiving groove 11 is fixed on the lower section between the two side plates of the support frame 1. The receiving groove 11 is located above the motor 7 and is set at an inclination. After the main support frame 3 is flipped, the welding debris can fall into the receiving groove 11 by gravity for collection, avoiding soiling the working environment floor and eliminating the need for manual cleaning. The inclination arrangement also helps the debris to concentrate at the lower part of the receiving groove 11, making it convenient for manual removal of the debris. The support frame also prevents the debris from falling onto the motor 7 and affecting the operation of the motor 7.
