Description

Technical Field

[0001] This application relates to the field of kettle manufacturing technology, and in particular to a welding apparatus for kettle manufacturing. Background Technology

[0002] In the kettle production process, the welding of the kettle body and spout is generally done manually, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure the consistency of welding quality.

[0003] An automated welding device for a kettle, disclosed in Chinese Patent Publication No. CN217253870U, uses a servo motor to drive a C-shaped crankshaft structure to achieve the positioning and rotation of the kettle body. It achieves rapid clamping and precise positioning of the kettle body and spout (two irregularly shaped structures) through a top-mounted synchronous pressure module, a rotating shaft, and a die clamp. An angular positioning of the rotating shaft is achieved without power using an insert-type synchronous pin. However, the device suffers from several drawbacks: the C-shaped crankshaft structure cannot support the curved kettle body, and the kettle body lacks a positioning and fixing device, making it difficult to maintain a relatively flat surface during welding, thus affecting welding quality. Furthermore, it involves numerous operation steps, requiring adjustment of the synchronous pin and loading / unloading, resulting in a relatively complex structure.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a welding apparatus for kettle production to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is: a welding device for kettle production, comprising: a kettle body and a spout, wherein the kettle body has a liquid outlet hole, and a welding device body, which includes a worktable and a mounting bracket mounted on the worktable. A motor is fixed below the worktable, and the output shaft of the motor passes through the worktable. A material feeding groove is provided on the mounting bracket, which is located directly above the output shaft of the motor. A laser welding device is provided on the mounting bracket. A C-shaped bracket is fixedly connected to the output shaft of the motor, including an upper bracket and a lower bracket. A positioning frustum is provided on the top of the upper bracket. The positioning frustum is on the same vertical line as the output shaft of the motor. A sliding groove is provided on the upper surface of the upper bracket, and a clamp for holding the kettle body slides in the sliding groove. An arc-shaped support plate for supporting the kettle body is rotatably provided at the end of the lower bracket. The positioning frustum limits the kettle body by passing through the liquid outlet hole. The spout can be fitted onto the positioning frustum. The motor drives the C-shaped bracket to rotate to perform the welding operation.

[0007] In some embodiments, the bend of the C-shaped bracket is a smooth arc.

[0008] In some embodiments, limiting protrusions are formed on both sides of the slide groove for limiting the clamp, and an mounting member is rotatably provided at the end of the slide groove for facilitating the assembly of the clamp. When the mounting member is locked on the C-shaped bracket, the end of the slide groove is blocked and the clamp is limited within the slide groove.

[0009] In some embodiments, the clamp includes a slider and an operating member, the slider and the operating member are hinged to each other and equipped with a torsion spring, the slider has lugs on both sides that cooperate with the limiting protrusions to limit the slider in the groove, the upper surface of the slider is flush with the upper surface of the upper bracket, and the operating member is used for manual operation to open and close the clamp.

[0010] In some embodiments, the slider is threaded with an operating screw, which is used to lock the position of the clamp.

[0011] In some embodiments, a pair of limiting plates are provided on each of the upper and lower sides of the feeding trough. The pair of limiting plates are symmetrically inclined toward the feeding trough, and there is a gap between adjacent limiting plates. Positioning grooves are provided on the limiting plates.

[0012] In some embodiments, a positioning hole with a diameter larger than the liquid outlet is provided at the location of the liquid outlet on the outer surface of the kettle body, and the positioning hole does not penetrate the kettle body.

[0013] The beneficial effects of this application are as follows:

[0014] 1. The positioning frustum on the C-shaped bracket, in conjunction with the liquid outlet on the body of the kettle, provides support for the kettle body while also limiting its position, and can accurately locate the part to be welded (i.e., the location of the liquid outlet on the kettle body). In addition, the positioning frustum can also position the spout. The spout passes through the positioning groove and is kept in a stable position under the action of the limiting plate until it is placed into the positioning hole. The C-shaped bracket rotates, and the kettle body and spout rotate synchronously to perform welding. The laser welding device is used, which has a relatively simple structure, is easy to operate, and has few operation steps.

[0015] 2. The C-shaped bracket is equipped with a clamp that slides in the groove and an arc-shaped support plate that rotates on the lower half of the bracket, providing fixation and support for the pot body, making the pot body more stable when rotating. The bend of the C-shaped bracket is arc-shaped, which allows the pot body to be tilted and fixed on the C-shaped bracket by the clamp, enabling welding of pot bodies with curvature and improving the adaptability of the welding device.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0025] In the embodiments of this application, please refer to Figure 1-6As shown, this welding device for kettle production mainly includes: a kettle body 1 and a spout 2, wherein the kettle body 1 has a liquid outlet hole 3; a welding device body, which includes a workbench 4 and a mounting bracket 5 mounted on the workbench 4; a motor 6 fixed below the workbench 4; the output shaft of the motor 6 passing through the workbench 4; a material feeding groove 7 located directly above the output shaft of the motor 6 on the mounting bracket 5; a laser welding device 8 mounted on the mounting bracket 5; and a C-shaped bracket 9 fixedly connected to the output shaft of the motor 6, including an upper bracket 901 and... The lower support 902 has a positioning frustum 10 at the top of the upper support 901. The positioning frustum 10 is on the same vertical line as the output shaft of the motor 6. The upper surface of the upper support 901 has a sliding groove 11. A clamp 12 for holding the kettle body 1 slides in the sliding groove 11. The lower support 902 has an arc-shaped support plate 13 for supporting the kettle body 1. The positioning frustum 10 limits the kettle body 1 by passing through the liquid outlet 3. The spout 2 can be fitted on the positioning frustum 10. The motor 6 drives the C-shaped bracket 9 to rotate for welding operations.

[0026] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0027] like Figure 4 As shown, in order to use the curved body 1, the bend of the C-shaped bracket 9 is a smooth arc. Therefore, the body 1 can be placed at an angle on the C-shaped bracket 9, so that the liquid outlet 3 is kept as horizontal as possible, which facilitates the next step of operation.

[0028] like Figure 1 As shown, limiting protrusions 14 are formed on both sides of the slide groove 11 to limit the clamp 12. The end of the slide groove 11 has a mounting member 15 for facilitating the assembly of the clamp 12. When the mounting member 15 is locked on the C-shaped bracket 9, the end of the slide groove 11 is blocked, and the clamp 12 is limited in the slide groove 11. Specifically, when the mounting member 15 rotates freely on the C-shaped bracket 9, the mounting member 15 does not block the end of the slide groove 11. The clamp 12 can be inserted between the slide groove 11 and the limiting protrusions 14 through this end. Finally, the mounting member 15 is locked on the C-shaped bracket 9 with fasteners to complete the assembly.

[0029] Furthermore, combined with Figure 5As shown, the clamp 12 includes a slider 1201 and an operating member 1202. The slider 1201 and the operating member 1202 are hinged to each other and equipped with a torsion spring 16. The slider 1201 has lugs 17 on both sides that cooperate with the limiting protrusion 14 to limit the slider 1201 in the slide groove 11. The upper surface of the slider 1201 is flush with the upper surface of the upper bracket 901. The operating member 1202 is used for manual operation to open and close the clamp 12.

[0030] Furthermore, the slider 1201 is threaded with an operating screw 20, which is used to lock the position of the clamp 12. When welding different sizes of pot body 1, the position of the clamp 12 in the slide groove 11 needs to be adjusted according to the actual situation. After adjusting to the appropriate position, the operating screw 20 is screwed to press against the bottom of the slide groove 11 to fix the clamp 12.

[0031] like Figure 2-3 As shown, a pair of limiting plates 18 are provided on each of the upper and lower sides of the feeding trough 7. The pair of limiting plates 18 are symmetrically inclined towards the feeding trough 7, and there is a gap between adjacent limiting plates 18. A positioning groove 19 is provided on the limiting plate 18. During feeding, the bottom of the spout 2 can only pass through the positioning groove 19, while the other parts of the spout 2 pass through the gap between the two limiting grooves. As the spout 2 passes through the limiting groove and the feeding trough 7, it is fitted onto the positioning frustum 10. When the spout 2 falls freely, the positioning... The limiting plate 18 below the feeding trough 7 can restrict the orientation of the spout 2 when it falls, so that the spout 2 maintains the correct orientation until it contacts the body 1. After that, when the motor 6 drives the C-shaped bracket 9 and the body 1 to rotate, the spout 2 can rotate synchronously with the body 1. It should be noted that after the spout 2 contacts the body 1, the top of the spout 2 is relatively thin and is located below the two limiting plates 18. There is sufficient gap between the two limiting plates 18 for the upper part of the spout 2 to rotate. Therefore, the limiting plates 18 do not interfere with the normal rotation of the spout 2 when it rotates.

[0032] like Figure 6 As shown, on the outer surface of the kettle body 1, a positioning hole 21 with a diameter larger than that of the liquid outlet 3 is provided at the location of the liquid outlet 3. The diameter of the positioning hole 21 is also larger than the bottom diameter of the spout 2. The positioning hole 21 does not penetrate the kettle body 1. After the spout 2 is placed through the feeding groove 7, due to the coaxiality of the output shaft of the motor 6, the positioning frustum 10, and the positioning groove 19, and the limiting of the limiting plate 18 and the positioning frustum 10, the spout 2 can fall into the positioning hole 21 with the correct orientation, so that the spout 2 maintains a certain friction with the kettle body 1 and can accurately position the welding position, which is convenient for the next step of laser welding. At the same time, through the heat control of laser welding and the smaller heat-affected zone, the dependence on the pressing of the spout 2 can be reduced, and the welding quality can be improved.

[0033] Specifically, when using this device, firstly, the outlet hole 3 on the body 1 is fitted onto the positioning frustum 10. If the body 1 has a curvature, the body 1 is tilted so that the outlet hole 3 remains basically horizontal. Next, the clamp 12 is used to hold the side wall of the body 1 to complete the fixation. When the body 1 is large, an arc-shaped support plate 13 is needed to provide support to maintain the stability of the body 1 and prevent excessive force on one side of the body 1 from causing damage. The arc-shaped support plate 13 rotates freely on the C-shaped bracket 9 to adaptively support the body 1. Then, the spout 2 falls freely through the upper limiting plate 18, the feeding trough 7, and the lower limiting plate 18, and is fitted onto the positioning frustum 10 with the correct orientation, and the bottom is placed in the positioning hole 21. After that, the motor 6 and The laser welding device 8 completes the welding. When welding different specifications of spout 2 and body 1 using the welding device, it is necessary to adjust the position of the clamp 12 in the slide groove 11 and the angle of the laser welding device 8 in advance. The laser welding device 8 in this application is a prior art known to those skilled in the art. Its main structure is installed on the mounting bracket 5. The example in the figure is the laser welding head on the laser welding device 8, which can be adjusted. The specific circuit connection, power supply, etc. are conventional technical means and will not be described in detail here. This application only requires manual operation of the body 1 and spout 2, and the clamp 12 to hold and fix the body 1. The steps are relatively simple and the device structure is relatively small. In addition, this device can also consider cost efficiency and other factors, and use industrial robots to automatically load and unload materials.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
