Description

Technical Field

[0001] The utility model relates to the technical field of storage box production and processing equipment, in particular to an automatic welding device for a trumpet-shaped stainless steel sheet metal part which is easy to assemble. Background Art

[0002] During the processing of the storage box, because the gap between the fireproof cotton in the storage box and the core box is relatively small, it is necessary to press down hard during the assembly of the core box. This operation method is easy to scratch the fireproof cotton on all sides, resulting in powder leakage. In order to solve the above problems, generally during the processing of the storage box, the lower cover of the storage box is bent and tilted outward by 3° to form a trumpet shape, so that the fireproof cotton and the core box are placed in the lower cover first, and then the lower cover is welded. Since the lower cover is tilted outward on all sides, a certain range of movement is provided for the fireproof cotton, which is convenient for placing the core box. However, this setting method requires that the trumpet-shaped opening of the lower cover must be pushed inward during the welding process for welding. If the pushing force during the welding process is unbalanced, it is easy to affect the welding effect, or cause undesirable conditions such as deformation of the lower cover.

[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0018] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] See also Figures 1 to 3The utility model provides an automated welding device for trumpet-shaped stainless steel sheet metal parts that is easy to assemble, comprising: a machine platform 1, a welding fixture 2 arranged on the machine platform 1, and a welding mechanism 3 suspended above the welding fixture 2, wherein the welding fixture 2 comprises: a limit seat 21 arranged on the machine platform 1, a placement position arranged on the limit seat 21, a limit fixing plate 22 arranged in two adjacent directions of the placement position, a pushing mechanism 23 arranged on the opposite side of the limit fixing plate 22, and a pushing plate 24 arranged on the output end of the pushing mechanism 23, wherein the limit fixing plate 22 and the pushing plate 24 surround the placement position and reserve welding positions 25 at the four corners of the placement position. When welding, the lower cover with fireproof cotton and core box is placed in the placement position, and the pushing mechanism 23 is started, thereby driving the pushing plate 24 to push the lower cover, so that the lower cover is pressed tightly between the pushing plate 24 and the limit fixing plate 22, thereby pressing the lower cover from four directions, so that the side wall of the lower cover is pushed to 90 degrees. Then, the welding mechanism 3 is used to weld the seams between the side walls of the lower cover at the welding position 25, so as to ensure the welding effect of the lower cover of the storage box.

[0020] The pushing mechanism 23 uses a cylinder, and the cylinder drives the pushing plate 24 to move toward the placement position. In some embodiments, a thin cylinder is used as the pushing mechanism 23, which can not only ensure the pushing effect on the side wall of the lower cover, but also reduce the space occupied on the machine platform.

[0021] The machine table 1 is provided with a rotating mechanism 4, and the welding fixture 2 is provided on the rotating mechanism 4. The rotating mechanism 4 drives the welding fixture 2 to rotate, so that different welding positions 25 are sequentially moved to the processing area position of the welding mechanism 3 for welding.

[0022] The welding mechanism 3 includes: a multi-axis moving mechanism 31 disposed on the machine 1, a welding gun bracket 32 ​​disposed on the moving end of the multi-axis moving mechanism 31, and a welding gun 33 disposed on the welding gun bracket 32. The multi-axis moving mechanism 31 drives the welding gun 33 to move. In some embodiments, the multi-axis moving mechanism 31 uses an X-axis moving module and a Z-axis moving module to drive the welding gun 33 to move along the X-axis direction and the Z-axis direction to achieve welding of the lower cover seam.

[0023] The machine 1 is provided with a Y-axis moving module, and the welding fixture 2 is provided on the Y-axis moving module. When it is necessary to place the workpiece, the welding fixture 2 is moved away from the welding mechanism 3 by the Y-axis moving module, so that the welding fixture 2 is close to the operator, which is convenient for placing the product to be welded on the welding fixture 2. In the case of large-scale processing, the displacement of the welding gun 33 is generally adjusted and fixed, and the welding gun 33 is basically not moved during the processing. In order to avoid the position displacement of the welding gun 3 caused by the welding gun 3 being hit when taking and placing the product, the welding fixture 2 is driven to move by the Y-axis moving module, which is convenient for taking and placing the product, and at the same time ensures that the operator's hands will not be burned by the welding gun, thereby improving safety.

[0024] During the welding process, the Y-axis moving module drives the welding fixture 2 to move along the Y-axis direction, thereby cooperating with the rotating mechanism 4 to adjust the position of the welding fixture 2 to meet the needs of welding processing on the product clamped on the welding fixture 2.

[0025] The machine platform 1 is provided with an illumination lamp 5. During the welding process, the illumination lamp 5 is used for illumination, so that the operator can observe the pressing and welding conditions of the welding position 25 and judge the welding effect.

[0026] See also Figure 4 The machine 1 is covered with a protective cover 6, and the protective cover 6 is provided with a safety door 61 corresponding to the material feeding and discharging and operation direction, and safety gratings 62 are provided on both sides of the safety door 61. During the welding process, the safety grating 62 is activated. At this time, if an object moves into the detection range of the safety grating 62, the safety grating 62 will send a corresponding detection signal to the control system, and control each mechanism to stop working through the control system, and send an alarm sound effect for warning.

[0027] The protective cover body 6 is provided with a display screen 63 and a control panel 64 . The display screen 63 is used to display images, and the control panel 64 is used to adjust the laser focal length to determine the welding position.

[0028] The specific processing flow of the utility model is:

[0029] Put the fireproof cotton into the trumpet-shaped open lower cover, and put the core box into the central groove of the fireproof cotton. Put the lower cover into the placement position of the welding fixture 2, so that the two sides of the lower cover are close to the limit fixing plate 22. Start the pushing mechanism 23, push the lower cover and press it between the pushing plate 24 and the limit fixing plate 22 through the pushing plate 24, squeeze the side wall of the lower cover, and thus press the four side walls of the lower cover into 90 degrees.

[0030] The welding mechanism 3 is started, and the four folding seams of the lower cover are welded through the welding position 25. During this process, the welding fixture 3 is driven to rotate by the rotating mechanism 4 to realize the sequential welding of the four folding seams.

[0031] Before welding, the laser focal length is fine-tuned by using the control panel 64 according to the image on the display screen 63, the red laser intersection is aligned with the position of the lower cover corner to be welded, and the welding mechanism 3 is started. The laser of the welding gun 33 generates a high-energy laser beam to achieve the welding of the joint. After the welding is completed, the pushing mechanism 23 is reset to facilitate the removal of the welded lower cover.

[0032] In summary, the utility model drives the push plate to push the lower cover through the push mechanism, so that the lower cover is pressed tightly between the push plate and the limit fixing plate, thereby pressing the lower cover from four directions and pushing the side wall of the lower cover to 90 degrees. Then, the welding mechanism is used to weld the seams between the four side walls of the lower cover at the welding position, so as to ensure the welding effect of the lower cover of the storage box. In this way, it can be ensured that the four sides of the lower cover are balanced during the welding process, and the bending angles of the four sides can be effectively guaranteed, so as to ensure the welding effect.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
