Description
Technical Field
[0001] This utility model belongs to the technical field of welding auxiliary equipment, and in particular, relates to a welding fixture for steel plate radiators. Background Technology
[0002] Plate radiators are widely used heat exchange devices in various fields. They consist of plate heat exchange components made up of multiple thin plates, which effectively and quickly transfer heat from a fluid to the air, achieving highly efficient heat exchange. Currently, to ensure the accuracy and stability of welding the steel fins of plate radiators, the steel fins are typically clamped and positioned precisely on the radiator body using fixtures on a welding jig. This ensures accurate alignment of the weld joint, helps reduce welding defects, and improves welding quality. However, the welding jig can usually only clamp and position a single steel fin at a time, welding each fin individually to the radiator body. Since the plate heat exchange component of a plate radiator consists of multiple steel fins, this requires multiple clamping and positioning operations using the welding jig, reducing welding efficiency.

[0021] Please refer to the following: Figures 1 to 8 The welding fixture for the steel plate radiator provided in this embodiment of the present invention will now be described. Please refer to the following for further details. Figure 1 , Figure 2 and Figure 3 The steel plate radiator welding fixture provided in this embodiment includes a base structure 1, a clamping and positioning device 2, a lifting device 3, and a locking structure 4. The base structure 1 includes a base 11, a rotating seat 12 rotatably mounted on the base 11 via a pivot 9, and a support seat 13 located on one side of the base 11. Please refer to further details. Figure 4 , Figure 5 and Figure 6 The clamping and positioning device 2 includes a first clamping assembly 21, a second clamping assembly 22, a first screw 23 rotatably mounted on a rotating seat 12 via bearings, two first nuts 24 threadedly connected to the first screw 23, a second screw 25 rotatably mounted on the rotating seat 12 via bearings, two second nuts 26 threadedly connected to the second screw 25, and a drive assembly 27 that drives the first screw 23 and the second screw 25 to rotate. The first clamping assembly 21 is respectively connected to one of the first nuts 24 and the second nut corresponding to that first nut 24. The first clamping assembly 21 is connected to the second clamping assembly 22, which is connected to the other first nut 24 and the corresponding second nut 26. The threads of the two first nuts 24 are in opposite directions, and the threads of the two second nuts 26 are in opposite directions. By synchronously rotating the first screw 23 and the second screw 25, the threads of the two first nuts 24 and the first screw 23, and the threads of the two second nuts 26 and the second screw 25, can drive the first clamping assembly 21 and the second clamping assembly 22 to move closer to or further away from each other. When the first clamping assembly 21 and the second clamping assembly 22 are close to each other, they can clamp and position multiple steel heat sinks 7. When the first clamping assembly 21 and the second clamping assembly 22 are far apart, they can release the multiple steel heat sinks 7 to release the clamping and positioning effect. Please refer to further details. Figure 1 , Figure 2 and Figure 8The lifting device 3 includes a lifting platform 31 and a lifting drive mechanism 32 for raising or lowering the lifting platform 31. The lifting drive mechanism 32 is mounted on the base 11, and the lifting platform 31 is mounted on the lifting drive mechanism 32. The lifting platform 31 has multiple positioning slots 34 for positioning and placing the steel heat sink 7. The locking structure 4 is used to lock the rotating seat 12 onto the base 11 or the support seat 13. For further details, please refer to the relevant documentation. Figure 1 , Figure 2 and Figure 3 The locking structure 4 includes a first alignment hole 41 on the rotating base 12, a second alignment hole 42 on the base 11 and / or support 13, a bolt 43 that can pass through the first alignment hole 41 and the second alignment hole 42 in sequence after the first alignment hole 41 and the second alignment hole 42 are aligned, and a locking nut 44 threadedly connected to the threaded rod of the bolt 43. In addition, the support 13 is provided with a locking position 131 for locking the positioning rotating base 12. When the locking structure 4 releases the locking effect between the rotating seat 12 and the support seat 13, it is only necessary to rotate the rotating seat 12 onto the base 11 and support and lock the rotating seat 12 onto the base 11, so that the clamping and positioning device 2 on the rotating seat 12 can be kept in the first preset position. At this time, the lifting drive mechanism 32 drives the lifting platform 31 to rise, so that the multiple steel heat sinks 7 positioned on the lifting platform 31 are located between the first clamping component 21 and the second clamping component 22 of the clamping and positioning device 2, so that the first clamping component 21 and the second clamping component 22 can clamp and position the multiple steel heat sinks 7 at the same time. When the first clamping assembly 21 and the second clamping assembly 22 clamp multiple steel heat sinks 7, the lifting drive mechanism 32 drives the lifting platform 31 to descend, so that the lifting platform 31 moves away from the first clamping assembly 21 and the second clamping assembly 22, avoiding interference between the lifting platform 31 and the first clamping assembly 21 and the second clamping assembly 22. Then, the rotating seat 12 is rotated so that the rotating seat 12 is supported on the support seat 13, and then the locking structure 4 locks the rotating seat 12 on the support seat 13. This allows the multiple steel heat sinks 7 to be simultaneously clamped and positioned at predetermined positions that can be welded to the plate heat sink body.
[0022] Compared with the prior art, the steel plate radiator welding fixture provided in this embodiment of the utility model, by setting the clamping and positioning device 2 on the rotating base 12, only needs to rotate the rotating base 12 onto the base 11, and the lifting drive mechanism 32 can drive the lifting platform 31 to rise, so that the multiple steel heat sinks 7 positioned on the lifting platform 31 are located between the first clamping component 21 and the second clamping component 22 of the clamping and positioning device 2, so that the first clamping component 21 and the second clamping component 22 can simultaneously clamp and position the multiple steel heat sinks 7. After the first clamping component 21 and the second clamping component 22 clamp the multiple steel heat sinks 7, the rotating base 12 is rotated onto the support base 13, so that the multiple steel heat sinks 7 can be synchronously clamped and positioned at a predetermined position that can be welded to the plate radiator body. In this way, multiple steel heat sinks 7 can be clamped and positioned simultaneously, so that multiple steel heat sinks 7 can be clamped and positioned at the predetermined position on the plate heat sink body at the same time. This solves the technical problem in the prior art that the plate heat sink welding fixture can only clamp and position a single steel heat sink 7 at a time, and the steel heat sink 7 needs to be clamped and positioned one by one by the plate heat sink welding fixture, which reduces the welding efficiency.
[0023] Please refer to the following: Figure 4 , Figure 5 and Figure 6In some embodiments, the first clamping assembly 21 includes a first movable seat 211 and a first clamping seat 212 disposed on the first movable seat 211. One end of the first movable seat 211 is fixedly connected to a corresponding first nut 24, and the other end of the first movable seat 211 is fixedly connected to a corresponding second nut 26. The second clamping assembly 22 includes a second movable seat 221 and a second clamping seat 222 disposed on the second movable seat 221. One end of the second movable seat 221 is fixedly connected to a corresponding first nut 24, and the other end of the second movable seat 221 is fixedly connected to a corresponding second nut 26. In this embodiment, with the above structural arrangement, since the threads of the two first nuts 24 have opposite helical directions, and the threads of the two second nuts 26 have opposite helical directions, by synchronously rotating the first screw 23 and the second screw 25, under the action of the threads of the two first nuts 24 and the first screw 23, and under the action of the threads of the two second nuts 26 and the second screw 25, the first movable seat 211 and the second movable seat 221 can be driven to move closer to each other or further away from each other. When the first movable seat 211 and the second movable seat 221 approach each other, the first clamping seat 212 on the first movable seat 211 and the second clamping seat 222 on the second movable seat 221 can clamp and position the multiple steel heat sinks 7. When the first movable seat 211 and the second movable seat 221 move away from each other, the first clamping seat 212 on the first movable seat 211 and the second clamping seat 222 on the second movable seat 221 can release the multiple steel heat sinks 7, thereby releasing the clamping and positioning function of the multiple steel heat sinks 7.
[0024] Please refer to the following: Figure 4 , Figure 5 and Figure 6 In some embodiments, the first clamping base 212 is provided with a plurality of first slots 213 for engaging and positioning the corresponding sides of the steel heat sink 7, and the distance between two adjacent first slots 213 is equal. The second clamping base 222 is provided with a plurality of second slots 223 for engaging and positioning the corresponding sides of the steel heat sink 7, and the distance between two adjacent second slots 223 is equal. The number of first slots 213 and second slots 223 is equal, and the first slots 213 and second slots 223 are arranged in a one-to-one correspondence. In this embodiment, by providing first slots 213 on the first clamping base 212 and second slots 223 on the second clamping base 222, the stability and reliability of the first clamping base 212 and the second clamping base 222 in clamping and positioning the steel heat sink 7 can be enhanced.
[0025] Please refer to the following: Figure 1 , Figure 2 and Figure 7In some embodiments, the width of the first slot 213 is equal to the thickness of the steel heat sink 7, the width of the second slot 223 is equal to the thickness of the steel heat sink 7, and the width of the positioning slot 34 is equal to the thickness of the steel heat sink 7. The positioning slot 34 is configured to correspond one-to-one with the first slot 213 and / or the second slot 223. In this embodiment, with the above-described structure, when the lifting drive mechanism 32 drives the lifting platform 31 to rise, each positioning slot 34 on the lifting platform 31 can be aligned with the corresponding first slot 213 on the first clamping seat 212, and each positioning slot 34 on the lifting platform 31 can be aligned with the corresponding second slot 223 on the second clamping seat 222. This allows for the rapid insertion of multiple steel heat sinks 7 from the lifting platform 31 into the corresponding first slots 213 on the first clamping seat 212 and the corresponding second slots 223 on the second clamping seat 222, thereby facilitating the quick and stable clamping and positioning of multiple steel heat sinks 7 by the clamping and positioning device 2.
[0026] Please refer to the following: Figure 5 and Figure 6 In some embodiments, a first rubber pad 5 is provided inside the first slot 213, and a second rubber pad 26 is provided inside the second slot 223. Through the elastic deformation of the first rubber pad 5 and the second rubber pad 26, the stability of clamping and positioning the steel heat sink 7 can be enhanced on the one hand, and the rigid contact between the steel heat sink 7 and the first clamping seat 212 and the second clamping seat 222 can be prevented on the other hand.
[0027] Please refer to the following: Figure 7 and Figure 8 In some embodiments, a straightening positioning piece 8 is provided between two adjacent positioning slots 34 for straightening the steel heat sink 7. On the one hand, it can enhance the stability of the steel heat sink 7 in the lifting platform 31, and on the other hand, it can separate two adjacent steel heat sinks 7.
[0028] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the lifting device 3 further includes multiple vertically arranged and parallelly spaced guide rods 33. The base 11 has guide holes 111 corresponding to the positions of each guide rod 33. Each guide rod 33 can be slidably inserted into the corresponding guide hole 111 along the axial direction, and the top end of each guide rod 33 is fixedly connected to the lifting platform 31. In this embodiment, the cooperation between the guide rods 33 and the guide holes 111 guides the lifting platform 31 to rise and fall, effectively preventing the lifting platform 31 from shifting or swaying during the lifting process.
[0029] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the lifting drive mechanism 32 is a cylinder, an electric cylinder, or an electric push rod.
[0030] Please refer to the following: Figure 1 , Figure 2 and Figure 4 In some embodiments, the drive assembly 27 includes a first synchronous pulley 271 fixedly mounted on the first screw 23, a second synchronous pulley 272 fixedly mounted on the second screw 25, a synchronous belt 273 drivingly connecting the first synchronous pulley 271 and the second synchronous pulley 272, and a rotating handwheel 274 that drives the first screw 23 or the second screw 25 to rotate. The rotating handwheel 274 is fixedly connected to the first screw 23 or the second screw 25. In this embodiment, simply rotating the rotating handwheel 274 will drive the first screw 23 and the second screw 25 to rotate via the synchronous belt 273, thereby achieving the clamping and loosening actions of the first clamping seat 212 and the second clamping seat 222. It is understood that a drive motor can also be provided, with its motor shaft drivingly connected to the first screw 23 or the second screw 25, so that the first screw 23 and the second screw 25 can rotate via the synchronous belt 273.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
