Description

Technical Field

[0001] This utility model relates to the field of welding transfer tooling technology, and in particular to a welding tooling with a transfer mechanism. Background Technology

[0002] Thermos cups are usually made of stainless steel. Due to the characteristics of stainless steel and design requirements, there are multiple seams inside the thermos cup that need to be welded. Welding can make the seams smooth, thereby avoiding cracks and gaps and ensuring the heat preservation effect. However, in the production of existing thermos cups, the welding fixtures are in the transfer device. In the case of large-scale, assembly line welding, the number of transfer devices is insufficient and cannot keep up with the production capacity demand. Based on this, a welding fixture with a transfer mechanism is proposed. Utility Model Content

[0005] As a further improvement to the above solution, the limiting and fixing mechanism includes a second clamping plate that is slidably connected to the inner side of the limiting platform. Each second clamping plate has a connecting rod fixedly connected to one side. Each connecting rod has a clamping plate driving mechanism at the end away from the limiting platform, which causes the second clamping plate to slide back and forth along the inside of the limiting platform.

[0006] As a further improvement to the above solution, the clamping plate driving mechanism includes a positioning block that is fixedly connected to one end of each of the connecting rods, and a pull rod is rotatably connected to the lower side of each positioning block. A slot mechanism for limiting the pull rod is provided on the fixed platform.

[0007] As a further improvement to the above solution, the slot mechanism includes a second slot and a first slot opened on the upper side of the fixed platform. The second slot and the first slot are connected end to end to form a closed annular groove, and the closed annular groove is configured to cooperate with the pull rod.

[0008] As a further improvement to the above solution, the welding mechanism includes a welding robot unit fixedly connected to one side of the base.

[0009] As a further improvement to the above solution, the transfer drive mechanism includes a gear ring fixedly connected to the lower side of the turntable, a servo motor fixedly connected to the upper side of the base, and a gear fixedly connected to the output end of the servo motor, the gear meshing with the gear ring.

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

[0011] 1. This utility model uses a turntable to drive multiple limiting tables, which pass sequentially under the welding robot unit to realize the welding operation. It is suitable for mass production and assembly line welding processes and has the advantage of high transfer efficiency.

[0012] 2. This utility model uses slot 1 and slot 2 to operate in conjunction with each other. When the pull rod is located in slot 2, clamping plates 1 and 2 open for feeding.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example:

[0020] Please combine Figure 1 - Figure 3This embodiment of a welding fixture with a transfer mechanism includes a base 1, a fixed platform 3 fixedly connected to the upper side of the base 1, the fixed platform 3 having a circular structure, a turntable 4 rotatably connected to the outer side of the fixed platform 3, the turntable 4 having an annular structure, six limiting platforms 5 fixedly connected to the upper side of the turntable 4, the limiting platforms 5 having T-shaped grooves inside, a clamping plate 6 fixedly connected to one side of each limiting platform 5, a limiting and fixing mechanism that cooperates with the clamping plate 6 to clamp on one side of each limiting platform 5, a welding mechanism on one side of the fixed platform 3, and a transfer drive mechanism for rotating the turntable 4 on the lower side of the turntable 4.

[0021] Please combine Figure 2 As shown, the limiting and fixing mechanism includes a second clamping plate 7 that is slidably connected to the inner side of the limiting platform 5. Each second clamping plate 7 has a connecting rod 8 fixedly connected to one side. Each connecting rod 8 has a clamping plate driving mechanism at the end away from the limiting platform 5, which causes the second clamping plate 7 to slide back and forth along the inside of the limiting platform 5.

[0022] Please combine Figure 2 As shown, the clamping plate driving mechanism includes a positioning block 10 that is fixedly connected to one end of each connecting rod 8. A pull rod 11 is rotatably connected to the lower side of each positioning block 10. The positioning block 10 is used to adjust the height of the pull rod 11 at one end of the connecting rod 8 to adapt to the needs of different slot depths and to replace the pull rod 11. A slot mechanism for limiting the pull rod 11 is provided on the fixed platform 3.

[0023] Please combine Figure 2 As shown, the slot mechanism includes a second slot 13 and a first slot 12 opened on the upper side of the fixed platform 3. The second slot 13 and the first slot 12 are connected end to end to form a closed annular groove. The closed annular groove is configured to cooperate with the pull rod 11. It should be noted that the second slot 13 and the first slot 12 have different curvatures. The second slot 13 and the first slot 12 are formed by splicing two arcs with different radii, wherein the radius of the first slot 12 is greater than the radius of the second slot 13.

[0024] Please combine Figure 1 As shown, the welding mechanism includes a welding robot unit 2 fixedly connected to one side of the base 1. The welding robot unit 2 is a 6-axis welding robotic arm. In this embodiment, only one welding robot unit 2 is set next to the base 1. In other embodiments, if multiple welding points need to be operated according to the actual welding process requirements, multiple welding robot units 2 can be set on the base 1, which is also within the protection scope of this utility model.

[0025] Please combine Figure 3 As shown, the transfer drive mechanism includes a gear ring 14 fixedly connected to the lower side of the turntable 4, a servo motor 16 fixedly connected to the upper side of the base 1, and a gear 15 fixedly connected to the output end of the servo motor 16, which meshes with the gear ring 14.

[0026] The implementation principle of a welding fixture with a transfer mechanism in this embodiment is as follows: The servo motor 16 starts, driving the gear ring 14 to rotate via the gear 15, directly pushing the turntable 4 to rotate around the fixed platform 3. When one end of the pull rod 11 is engaged in the second slot 13, the second clamping plate 7 slides to one side along the inside of the limiting platform 5, opening with the first clamping plate 6 for loading the product to be welded. Under the rotation of the turntable 4, the pull rod 11 slides from the first slot 12 into the second slot 13, pushing the second clamping plate 7 to the other side via the connecting rod 8, closing with the first clamping plate 6, forming a clamping and fixing of the welded product. When the turntable... 4. The rotating turntable 4 drives the clamped and positioned welding products to come under one or more welding robot units 2 one by one. When the rotation stops, the welding robot unit 2 can then weld the products. After the welding is completed, the turntable 4 starts to rotate again, and the products that have completed one welding process are rotated to the next welding process to continue to receive welding operations. When all welding points are completed, that is, after the turntable 4 has rotated one revolution, the pull rod 11 slides from the second slot 13 into the first slot 12 again. At this time, the second clamping plate 7 is pulled open again by the connecting rod 8 and the pull rod 11, that is, the second clamping plate 7 and the first clamping plate 6 are opened. At this time, the welded products can be unloaded.

[0027] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
