Description

Technical Field

[0001] This utility model relates to the technical field of welding fixtures, and in particular to a welding fixture. Background Technology

[0002] Currently, most welding fixtures only have one receiving slot, which is used to place the two objects to be welded. Before laser welding, the two objects need to be pre-pressed by a pressure plate to ensure the welding quality. This type of welding fixture with a single receiving slot is difficult to meet the welding requirements of high-efficiency production. A small number of welding fixtures currently have multiple receiving slots to facilitate faster welding of more objects, thereby improving welding efficiency. However, due to the errors in the depth of each receiving slot and the error in the height of the objects being welded, the pressure plate used in existing welding fixtures cannot guarantee that the two objects in all receiving slots can be pressed tightly. This often results in weak welds. Therefore, it is necessary to improve the existing welding fixtures. Utility Model Content

[0003] This utility model provides a welding fixture, which mainly solves the technical problem of how to ensure that all objects to be welded can be pressed tightly under the premise that the welding fixture is provided with multiple receiving slots.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A welding fixture includes a base plate, a cover plate, multiple positioning blocks, multiple quick clamps, and multiple elastic elements;

[0006] Multiple positioning blocks are slidably connected to the base plate in the longitudinal direction. Each positioning block has a receiving groove on its top for placing an object to be welded. The cover plate is placed on top of the base plate and is detachably connected to the base plate. When the cover plate is placed on top of the base plate, multiple positioning blocks are located between the base plate and the cover plate. The top of the base plate has quick clamps at at least at opposite ends. The quick clamps apply downward pressure to the cover plate so that the cover plate abuts against the top surface of the base plate. At least one elastic element is provided below each positioning block. The positioning block has an upward tendency to move towards the bottom surface of the cover plate due to the elastic force of the corresponding elastic element. The top of the cover plate has through holes for laser penetration at the positions corresponding to each receiving groove.

[0007] In one of the technical solutions, the welding fixture further includes a fixing plate, which is fixed to the bottom of the base plate, and one end of the plurality of elastic elements away from the positioning block abuts against the top surface of the fixing plate.

[0008] In one technical solution, the bottom surface of the base plate is provided with a first groove, the bottom of the first groove is provided with a plurality of second grooves, the bottom of the second groove is provided with a through hole penetrating the top surface of the base plate, the plurality of positioning blocks pass through the first groove and a corresponding second groove and then protrude upward from the corresponding through hole, the fixing plate is received in the first groove, the plurality of elastic elements are received in the second groove, and the positioning blocks are subjected to the elastic force of the elastic elements and have an upward tendency to abut against the bottom surface of the second groove.

[0009] In one of the technical solutions, the elastic element is a spring, and four elastic elements are housed in each of the second grooves, so that four elastic elements are provided at the bottom of each positioning block.

[0010] In one of the technical solutions, the welding fixture includes four positioning blocks, the bottom of the first groove is provided with four second grooves, and the top of the cover plate is provided with four clearance holes.

[0011] In one of the technical solutions, the top of the base plate is provided with a plurality of positioning posts protruding upwards, and the bottom of the cover plate is provided with a plurality of positioning holes for engaging with a corresponding positioning post.

[0012] In one of the technical solutions, when the quick clamp is in the open state where it is not pressing the cover plate, the quick clamp is located outside the path of the cover plate moving upward.

[0013] In one of the technical solutions, guide sleeves are embedded at least at opposite ends of the bottom of the base plate.

[0014] In one of the technical solutions, the welding fixture further includes a pad block, which is fixed to the top of the base plate, and the quick clamp is fixed to the top of the pad block.

[0015] In one of the technical solutions, a flexible pressure head is fixed on the quick clamp for directly applying pressure to the top surface of the cover plate.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Please refer to the following: Figures 1 to 4This utility model provides a welding fixture, which mainly includes a base plate 1, a cover plate 2, multiple positioning blocks 3, multiple quick clamps 4, and multiple elastic elements 5. The multiple positioning blocks 3 are slidably connected to the base plate 1 in the longitudinal direction, and each positioning block 3 has a receiving groove 31 on its top for placing two objects 10 to be welded. The cover plate 2 is placed on top of the base plate 1. When the cover plate 2 is placed on top of the base plate 1, the multiple positioning blocks 3 are located between the base plate 1 and the cover plate 2. Therefore, the cover plate 2 is designed to be detachably connected to the base plate 1, so that the operator can remove the cover plate 2 to place the objects 10 to be welded into the receiving grooves 3 of the positioning blocks 3. 1. Inside; wherein, at least at opposite ends of the top of the base plate 1, the aforementioned quick clamps 4 are respectively provided. The quick clamps 4 are used to apply downward pressure to the cover plate 2, so that the cover plate 2 can abut against the top surface of the base plate 1, thereby ensuring that the cover plate 2 can maintain a stable state relative to the base plate 1; wherein, at least one of the aforementioned elastic elements 5 is provided below each of the plurality of positioning blocks 3. After being subjected to the elastic force of the corresponding elastic element 5, the positioning block 3 has a tendency to move downward to approach the bottom surface of the cover plate 2. In addition, the top of the cover plate 2 is provided with through clearance holes 21 at the positions corresponding to each receiving groove 31. These clearance holes 21 are used for laser to pass through, so that the two objects to be welded located in the receiving groove 31 can be laser welded.

[0032] Specifically, in this embodiment, the two objects 10 to be welded located in each receiving slot 31 are illustrated by the oil cup and transparent top cover of an electronic atomizer product. When using the welding fixture of this solution, first take out the cover plate 2, and then put the oil cup and transparent top cover into the receiving slot 31 of each positioning block 3, with the transparent top cover located above the oil cup. Then, put the cover plate 2 on and drive the quick clamp 4 to clamp the cover plate 2. At this time, each transparent top cover will be subjected to the elastic force of the elastic element 5 below and abut against the bottom surface of the cover plate 2, so that there is a certain pre-pressure between the transparent top cover and the oil cup. Finally, the entire welding fixture containing multiple oil cups and multiple transparent top covers can be moved to the welding station and welded by laser welding. After welding is completed, the quick clamp 4 is moved to open and the cover plate 2 is removed, and multiple welded objects can be taken out.

[0033] As can be seen from the above, the welding fixture of this embodiment has the advantages of simple structure and convenient operation. Moreover, the welding fixture of this embodiment can ensure that multiple objects can be flexibly pressed together, thereby avoiding the phenomenon of product incomplete welding caused by differences in product height and size. In this way, the welding efficiency of the product is improved while the welding quality of the product is also improved.

[0034] Please refer to the following: Figure 3 and Figure 4The welding fixture in this embodiment also includes a fixing plate 6, which is fixed to the bottom of the base plate 1. The ends of the multiple elastic elements 5 away from the positioning block 3 abut against the top surface of the fixing plate 6. Thus, the fixing plate 6 is used to restrict the bottom end of the elastic elements 5, so that the elastic elements 5 can apply an upward elastic force to the positioning block 3.

[0035] Please refer to them again. Figure 3 and Figure 4 The bottom surface of the base plate 1 is provided with a first groove 11, and the bottom of the first groove 11 is provided with a plurality of second grooves 12. The number of second grooves 12 is actually the same as the number of positioning blocks 3. The bottom of the second groove 12 is provided with a through hole 13 penetrating the top surface of the base plate 1. When installing the positioning block 3, the positioning block 3 needs to pass through the first groove 11 and a corresponding second groove 12 from bottom to top and then protrude upward from the corresponding through hole 13. The positioning block 3 can slide up and down along the through hole 13, thereby realizing the sliding connection between the positioning block 3 and the base plate 1. The aforementioned fixing plate 6 is housed in the first groove 11, and the aforementioned plurality of elastic elements 5 are housed in the second grooves 12. After being subjected to the elastic force of the elastic elements 5, the positioning block 3 has a tendency to move upward and abut against the bottom surface of the second groove 12. It can be seen that the bottom of the second groove 12 can restrict the positioning block 3 from detaching upward from the base plate 1. Moreover, by providing the aforementioned first groove 11 and second groove 12, it is beneficial to reduce the thickness of the welding fixture. Preferably, all elastic elements 5 are springs, and each second groove 12 contains four elastic elements 5, so that each positioning block 3 has four elastic elements 5 at its bottom. Under the elastic force of the four elastic elements 5, the positioning block 3 can move stably up and down relative to the base plate 1. Correspondingly, the bottom of the positioning block 3 is provided with four limiting holes 32, and one end of each of the four elastic elements 5 is received in a corresponding limiting hole 32, thereby ensuring that the elastic force of the multiple elastic elements 5 on the positioning block 3 is always mainly maintained in the longitudinal direction.

[0036] Please refer to the following: Figures 1 to 4 In this preferred embodiment, the welding fixture includes four positioning blocks 3. Correspondingly, the bottom of the first groove 11 is provided with four second grooves 12, and the top of the cover plate 2 is provided with four clearance holes 21. With this design, one welding fixture can clamp four oil cups and four transparent top covers, which is conducive to quickly realizing the welding operation of four oil cups and four transparent top covers.

[0037] Please see Figure 1The top of the base plate 1 has multiple upward-protruding positioning posts 7, and the bottom of the cover plate 2 has multiple positioning holes 22. The number of positioning holes 22 is the same as the number of positioning posts 7. The multiple positioning holes 22 are used to cooperate with a corresponding positioning post 7, thereby improving the positional accuracy of the cover plate 2 on the base plate 1 and ensuring that each clearance hole 21 can accurately correspond to the object 10 to be welded. This ensures that the subsequent laser can accurately weld multiple objects 10 to be welded. Since the cover plate 2 is taken out upward in this scheme, when the quick clamp 4 is in the open state without pressing the cover plate 2, the quick clamp 4 needs to be located outside the upward movement path of the cover plate 2 so that the cover plate 2 can be easily taken out upward relative to the base plate 1.

[0038] Please see Figure 1 The welding fixture in this embodiment also includes a pad 8, which is fixed to the top of the base plate 1. The quick clamp 4 is fixed to the top of the pad 8. By setting the pad 8, the quick clamp 4 can be supported at a suitable working height. Furthermore, a flexible pressure head 41 is preferably fixed to the quick clamp 4. Applying pressure directly to the top surface of the cover plate 2 through the flexible pressure head 41 can prevent the quick clamp 4 from damaging the surface of the cover plate 2. Please refer to [link / reference]. Figure 4 The bottom of the base plate 1 is embedded with guide sleeves 9 at least at opposite ends. By setting the guide sleeves 9, the entire welding fixture can be smoothly and accurately placed on the welding station, which makes it easy to place or remove the entire welding fixture and helps to improve the accuracy of laser welding of multiple objects.

[0039] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
