Description

Technical Field

[0001] The utility model relates to the technical field of welding clamping, in particular to a welding clamping tool for radiator headers. Background Technique

[0002] Radiators are one of the extremely common furniture in the prior art. An entire radiator is generally composed of multiple radiator fins welded to each other. A radiator often contains several or even dozens of radiator headers. Thus, when welding, these radiator headers need to be clamped and fixed, and then welded. For such welding clamping devices for radiator headers in the prior art, when clamping the radiator headers, it is generally sequential clamping, that is, after welding one radiator header, then clamping the next radiator header until multiple radiator headers are welded and fixed together. Such sequential clamping requires repeatedly opening and closing the fixture, which is rather troublesome to operate. Therefore, in view of this problem, a welding clamping tool for radiator headers is needed for improvement. Content of the Utility Model

[0003] The purpose of the utility model is to provide a welding clamping tool for radiator headers to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A welding clamping tool for radiator headers, including a bracket. The upper end of the bracket is movably provided with a connecting shaft through a bearing. A clamping mechanism is arranged in the middle of the connecting shaft. The clamping mechanism includes a function chamber, a pressing rod, a radiator header, a limiting rod, a connecting rod, and a screw rod. A function chamber is fixedly arranged in the middle of the connecting shaft. Both sides inside the function chamber are movably inserted with pressing rods. A number of radiator headers are movably sleeved on the outer surface of the pressing rods. The upper ends of the pressing rods are movably provided with limiting rods through rotating shafts. A connecting rod is fixedly arranged between the lower ends of the pressing rods. The middle part inside the function chamber is movably provided with a screw rod through a bearing. The middle part inside the connecting rod is movably sleeved on the outer surface of the screw rod through a thread.

[0005] Preferably, a turning block is fixedly arranged at the lower end of the screw rod. The screw rod can be conveniently rotated through the turning block.

[0006] Preferably, self-locking universal wheels are movably arranged at the four corners of the lower end surface of the bracket. The device can be conveniently moved through the self-locking universal wheels. The device can be moved to a suitable working position for welding work. And because it can be self-locked, the device can be locked and fixed during welding.

[0007] Preferably, a rotating disk is fixedly arranged at one end of the connecting shaft, an installation frame is fixedly arranged on one side of the surface of the bracket, a fixing block is fixedly arranged at the upper end of the installation frame, a notch is arranged on the surface of the fixing block, and the rotating disk is snap-fitted inside the notch. The angle of the rotating shaft can be conveniently fixed through the rotating disk, so as to fix the function bin and the angle of the radiator fin head at the upper end of the function bin, so as to find the most suitable welding angle for the staff.

[0008] Preferably, a locking screw is rotatably screwed on one side of the surface of the fixing block. The locking screw can be screwed and tightened, and then the rotating disk is squeezed by the locking screw, so as to fix the rotating disk.

[0009] Preferably, a handle is fixedly arranged on the outer surface of the locking screw, and the locking screw can be conveniently rotated through the handle.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] In the utility model, a plurality of radiator fin heads are simultaneously sleeved on the outer surface of the extrusion rod. At this time, it is necessary to ensure that the limiting rod is parallel to the extrusion rod. When all the radiator fin heads are sleeved on the outer surface of the extrusion rod, the limiting rod is rotated to make the limiting rod perpendicular to the extrusion rod. Subsequently, by rotating the screw rod, the connecting rod and the extrusion rod are driven by the screw rod to move downward. At this time, with the help of the horizontal limiting rod and the function bin, a plurality of radiator fin heads can be quickly and conveniently squeezed and fixed. In this way, the radiator fin heads of a plurality of radiators can be clamped at one time, and then the radiator fin heads are welded together in sequence. Such a one-time clamping can save the steps of clamping one by one, thereby improving the processing efficiency.

[0012] When the utility model is used, the function bin can be rotated, so as to find the most suitable welding angle according to each person's welding habit. After the function bin is rotated to a suitable angle, the locking screw can be screwed and tightened, and then the rotating disk is squeezed by the locking screw, so as to fix the rotating disk.

A screw 8 is movably arranged in the middle of the inner side of the function bin 3 through a bearing. The middle of the inner side of the connecting rod 7 is movably sleeved on the outer surface of the screw 8 through a thread.

[0020] A turning block 9 is fixedly arranged at the lower end of the screw 8. The screw 8 can be conveniently rotated through the turning block 9;

[0021] Self-locking universal wheels 10 are movably arranged at the four corners of the lower end surface of the bracket 1. The device can be conveniently moved through the self-locking universal wheels 10. The device can be moved to a suitable working position for welding work. Since it can be self-locked, the device can be locked and fixed during welding for welding;

[0022] One end of the connecting shaft 2 is fixedly provided with a rotating disk 11. One side of the surface of the bracket 1 is fixedly provided with a mounting frame 12. The upper end of the mounting frame 12 is fixedly provided with a fixing block 13. A notch 14 is provided on the surface of the fixing block 13. The rotating disk 11 is snap-fitted inside the notch 14. The angle of the rotating shaft can be conveniently fixed through the rotating disk 11, so as to fix the function bin 3 and the angle of the radiator fin head 5 at the upper end of the function bin 3, so as to find the most suitable welding angle for the staff;

[0023] One side of the surface of the fixing block 13 is movably screwed with a locking screw 15 through threads. The locking screw 15 can be screwed and tightened, and then the rotating disk 11 is squeezed by the locking screw 15, so as to fix the rotating disk 11;

[0024] A handle 16 is fixedly provided on the outer surface of the locking screw 15. The locking screw 15 can be conveniently rotated through the handle 16.

[0025] Working principle: When using this device, this device can fix multiple radiator fin heads 5 at one time. When fixing the radiator fin heads 5, align the water through holes on the surface of the radiator fin heads 5 (this water through hole is an inevitable structure in the prior art radiator fin head 5, a hole for heating water to enter and a hole for heating water to discharge, running through the entire radiator fin head 5) with the extrusion rod 4, so that multiple radiator fin heads 5 are simultaneously sleeved on the outer surface of the extrusion rod 4. At this time, it is necessary to ensure that the limiting rod 6 is parallel to the extrusion rod 4. When the radiator fin heads 5 are all sleeved on the outer surface of the extrusion rod 4, rotate the limiting rod 6 so that the limiting rod 6 is perpendicular to the extrusion rod 4. Then, by rotating the screw rod 8, the connecting rod 7 and the extrusion rod 4 are driven to move downward by the screw rod 8. At this time, with the horizontal limiting rod 6 cooperating with the function bin 3, multiple radiator fin heads 5 can be quickly and conveniently squeezed and fixed. In this way, multiple radiator fin heads 5 of radiators can be clamped at one time, and then multiple radiator fin heads 5 are welded together in sequence. Such a one-time clamping can save the steps of clamping one by one, thereby improving the processing efficiency;

[0026] And when this device is used, the function bin 3 can rotate, so as to find the most suitable welding angle according to each person's welding habit. After the function bin 3 rotates to a suitable angle, the locking screw 15 can be screwed and tightened, and then the rotating disk 11 is squeezed by the locking screw 15, so as to fix the rotating disk 11.
