Description

Technical Field

[0001] This utility model belongs to the field of soldering fixture technology, and in particular relates to a quick clamping structure for soldering fixtures. Background Technology

[0002] In modern industrial manufacturing, welding, as a key joining technology, is widely used in various industries such as automotive, aerospace, shipbuilding, construction, and energy. During the welding process, ensuring precise alignment and stable fixation of the welded components is crucial for obtaining high-quality weld joints. Therefore, welding fixtures, as important tools assisting welding operations, directly affect welding efficiency, accuracy, and finished product quality through their design rationality and functionality.

[0003] In traditional soldering jig production, three pressure blocks (left, front, and back) are screwed onto the jig body. The product is then soldered together by melting the solder at high temperature in a rolling electric furnace. After cooling, the screws need to be removed with an electric screwdriver. This process is time-consuming and inefficient.

[0004] Patent CN207807013U discloses a quick-clamping solder clamp, including a base plate, a lower clamping plate on the top of the base plate, clamping seats at the four corners of the bottom of the lower clamping plate, an arc-shaped groove on the surface of the lower clamping plate, a support plate on the top of the lower clamping plate, a connecting plate on the front side of the support plate, an upper clamping plate on the front side of the connecting plate, and a slot at the bottom of the lower clamping plate.

[0005] The present invention has a complex structure and is cumbersome to operate, so it is necessary to improve this existing technology. Utility Model Content

Therefore, it should not be construed as a limitation of this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0031] In one embodiment of this utility model, such as Figures 1-5 As shown, a quick-clamping structure 200 for soldering jigs is provided, including a jig body 100 and a clamping structure 200. The jig body 100 is provided with a fixing part 110 for placing a workpiece 1 and a clamping part 150 for clamping the workpiece 1. The clamping part 150 includes a first abutment 151 and a second abutment 152. Specifically, the workpiece 1 is placed on the fixing part 110, and a portion of the workpiece 1 can be placed on the clamping part 150. Then, the clamping part 150 is detachably installed on the clamping part 150 to clamp and fix the portion of the workpiece 1 located on the clamping part 150. The clamping structure 200 also includes a clamping block 210 and an elastic clamping plate 250. The elastic clamping plate 250 is installed on the side wall of the clamping block 210 and abuts against the side wall of the clamping part 150. Under the action of elastic deformation, the two are interference-fitted to clamp and fix the workpiece on the jig.

[0032] Specifically, two workpieces to be welded are placed on a jig. The part of the workpiece to be welded is placed on the fixing part 110 of the jig body 100, while the non-welded part is placed on the clamping part 150. Then, the clamping structure 200 is fitted onto the clamping part 150 to clamp the workpiece. Then, the welding equipment welds the workpiece 1 to be processed on the fixing part 110.

[0033] Preferably, the clamping block 210 is T-shaped, and the side wall of the clamping block 210 is divided into a short wall 211 and a long wall 212. The elastic clamping plate 250 is fixed to the short wall 211 by bolts. The number of elastic clamping plates 250 is at least 3, and in this embodiment, there are 3 to clamp the weldment 1 from three directions. The bottom of the clamping plate near the long wall 212 is provided with a guide plate 220. The clamping block 210 is T-shaped to save materials and better correspond to the fixture body 100. It is not limited to this shape. The number of elastic clamping plates 250 is not limited to 3. It can be more than 3, which does not exceed the protection scope of this utility model. The guide plate 220 can better fit the clamping structure 200 into the clamping part 150 and plays a guiding role for the clamping structure 200.

[0034] Preferably, the distance between the first abutment plate 151 and the second abutment plate 152 on the clamping part 150 is equal to the width of the guide plate 220, and the bottom end of the guide plate 220 is provided with a guide head 221 that narrows towards its centerline. The distance between the abutment plates is equal to the width of the guide plate 220, which increases the fixing effect of the clamping structure 200. The guide head 221 also allows the guide plate 220 to slide more smoothly into the distance between the first abutment plate 151 and the second abutment plate 152 when the clamping structure 200 is fitted into the clamping part 150.

[0035] Preferably, the outer walls of the first abutment plate 151 and the second abutment plate 152 are provided with grooves 1511 for placing the weldment 1. The shape of the grooves 1511 is not limited, as long as they can accommodate the part of the weldment 1 that needs to be clamped. Welding ribs 111 are provided on the fixing part 110 on the fixture body 100 for connecting the two workpieces that need to be welded.

[0036] Preferably, the elastic clamping plate 250 has an upwardly inclined lifting foot 251 near the bottom, which allows the lifting foot 251 to easily slide across the weldment 1 when the clamping structure 200 is sleeved on the clamping part 150. Then the main body of the clamping plate clamps the weldment 1 and fixes it on the clamping part 150. It is worth mentioning that the shape of the lifting foot 251 is not limited. If only the shape of the lifting foot 251 is changed without any substantial change in function, it does not exceed the protection scope of this utility model.

[0037] 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.
