Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-6 This utility model provides an embodiment of a sleeve welding fixture for battery tray production, including a battery tray 1, a crossbeam 2 at the middle of the battery tray 1, a detachable welding auxiliary fixture 3 on the crossbeam 2, a sleeve 4 placed in the slot of the welding auxiliary fixture 3, the welding auxiliary fixture 3 including a limiting sleeve plate 31, the inner side of the limiting sleeve plate 31 being fitted and connected to the outer side of the sleeve 4, the left and right ends of the limiting sleeve plate 31 having limiting openings 311, the top protrusion of the support plate 32 being inserted into the limiting openings 311, the bottom of the support plate 32 being welded to the top of the base plate 33, the bottom of the base plate 33 being fitted and connected to the top of the crossbeam 2, and the front and rear ends of the base plate 33 having position adjustment mechanisms 34.

[0024] The top protrusion of the support plate 32 has slots 321 at both ends. A spring 322 is installed inside each slot 321. One end of the spring 322 is fixedly connected to one side of the positioning block 323. The positioning block 323 corresponds to the positioning groove 324 inside the limiting sleeve 31. The positioning block 323 has a semi-cylindrical structure, and its diameter is smaller than the diameter at the opening of the slot 321. The arc-shaped surface of the positioning block 323 fits snugly against the inner side of the positioning groove 324. The top protrusion of the support plate 32 is then inserted into the limiting sleeve. During insertion, the positioning block 323 is squeezed into the slot 321 by the spring 322 within the limiting port 311 of the positioning plate 31. When the support plate 32 is fully inserted, the positioning block 323 pops out under the elastic force of the spring 322 and is locked into the positioning groove 324 on the inner side of the limiting plate 31, thereby completing the connection between the limiting plate 31 and the support plate 32. At the same time, it ensures that the limiting plate 31 is in a horizontal state, and avoids affecting the position of the sleeve 4 due to the tilt of the limiting plate 31.

[0025] The position adjustment mechanism 34 includes a side plate 340 disposed at the bottom of two base plates 33. The angle between the side plate 340 and the base plate 33 is a right angle. A clamping plate 341 is provided on the outer side of the side plate 340. The inner protrusion of the clamping plate 341 is inserted into the outer groove of the side plate 340. A connecting plate 342 is provided on the left side of the top of the clamping plate 341 at the right end. An outer tube 343 is provided on the right side of the top of the clamping plate 341 at the left end. The left end of the connecting plate 342 is welded to the right end of the pull rod 344. The left end of the pull rod 344 is inserted into the outer tube 343. A pressing plate 345 is provided on the left end of the pull rod 344. The outer side of the pressing plate 345 is attached to the inner side of the outer tube 343. The right side of the pressing plate 345 is fixedly connected to the left end of the second spring 346 inside the outer tube 343.

[0026] The included angle between the side plate 340 and the bottom plate 33 is the same as the included angle between the tops of both ends of the crossbeam 2. First, place the bottom plate 33 on top of the crossbeam 2. Since the included angle between the side plate 340 and the bottom plate 33 is the same as the included angle between the tops of both ends of the crossbeam 2, it can ensure that the bottom plate 33 fits well with the crossbeam 2.

[0027] If it is necessary to adjust the position of the welding auxiliary fixture 3 on the crossbeam 2, pull the clamping plate 341 located at the right end. The connecting plate 342 will drive the pull rod 344 to move outward, and the pressing plate 345 will compress the second spring 346 inside the outer tube 343, causing the clamping plate 341 to loosen from the side plate 340. At this time, the welding auxiliary fixture 3 can be moved along the crossbeam 2. After reaching the appropriate position, release the clamping plate 341. The second spring 346 will rebound, pushing the pressing plate 345 and the pull rod 344 to reset. The clamping plate 341 will clamp the side plate 340, fixing the position of the welding auxiliary fixture 3 and preventing the position of the welding auxiliary fixture 3 from shifting during the welding process.

[0028] The sleeve 4 is placed in the slot of the welding auxiliary tooling 3. Because the limiting sleeve 31 fits against the sleeve 4, it can position and fix the sleeve 4, and then the welding operation is carried out.

[0029] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
