Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal welding equipment, in particular to a drum welding machine. Background Art

[0002] At present, in the welding operation between the drum and the bottom of the drum, most of them are manual operations, which are time-consuming and labor-intensive, and the degree of automation is not high. Although a small number of them use mechanical equipment for clamping and welding, the clamping and positioning effect of the drum is not good, and it is not convenient to clamp and rotate the drum, which greatly affects the welding accuracy and welding effect, and the welding parts cannot be protected, and the practicality is not high.

[0003] When the user holds a welding gun to weld the joint of the two barrel bodies, since the two barrel bodies are fixed, the user can only weld the arc at the upper end of the barrel body. Since the barrel body cannot rotate, it is not convenient for the user to weld the arc at the lower end of the two barrel bodies.

[0004] During the barrel welding process, the plate is first bent to form a barrel-shaped structure. At this time, there is a groove to be welded in the middle of the barrel. Then the barrel is placed in the limiting column, and then the groove is welded by the welding gun above. The welding gun is driven by the linear unit to perform linear welding processing. After completion, the welded barrel is taken out.

[0005] However, when the barrel is placed in the limiting column, the welding slot is often not aligned with the welding gun above, and manual adjustment is required. Otherwise, accurate welding is impossible, and the whole process is time-consuming and laborious. At the same time, the barrel needs to be fixed during the welding process, otherwise it will cause welding deviation.

[0006] Therefore, there is an urgent need for a drum welding machine that is convenient for aligning the grooves of the drum with the welding gun and can fix the drum during welding. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] like Figure 1-Figure 5 As shown, a drum welding machine comprises a machine base 1, a linear welding machine 2 and a limiting column 3, wherein the limiting column 3 is located below the linear welding machine 2, one end of the limiting column 3 is connected to the machine base 1, a drum 7 is sleeved outside the limiting column 3, the outer dimension of the limiting column 3 is adapted to the inner dimension of the drum 7, a first slot 301 is provided above the limiting column 3 corresponding to the welding head direction of the linear welding machine 2, the width of the first slot 301 is the same as the welding slot width of the drum 7, a limiting assembly 4 is provided inside the limiting column 3, the limiting assembly 4 comprises an upper slider and a lower slider, the upper slider extends out of the limiting column 3 through the first slot 301, and the limiting assembly 4 is used to limit the circumferential rotation of the drum 7 on the limiting column 3;

[0028] A mounting plate 5 is provided between the limiting column 3 and the linear welding machine 2, and the mounting plate 5 is provided with a second slot 501 corresponding to the welding head direction of the linear welding machine 2, the width of the second slot 501 is greater than the first slot 301, and the length of the second slot 501 is the same as the length of the limiting column 3, one end of the mounting plate 5 is connected to the machine base 1, and the other end of the mounting plate 5 is provided with a clamping assembly 6, the clamping assembly 6 is hinged to the mounting plate 5, the clamping assembly 6 cooperates with the limiting assembly 4, the upper slider slides up and down along the first slot 301 through the clamping assembly 6, and the clamping assembly 6 is also used to limit the movement of the barrel 7 on the limiting column 3 along the axial direction.

[0029] Through the above technical solution, since the length of the limiting column 3 is the same as the length of the barrel 7, and the diameter of the limiting column 3 is the same as the outer diameter of the barrel 7, the barrel 7 after rolling is inserted into the limiting column 3 to complete the limiting. Since the upper slider is exposed above the limiting column 3, the welding groove of the barrel 7 is inserted against the upper slider to complete the limiting of the barrel 7 in the circumferential direction, ensuring that the welding groove of the barrel 7 faces the second slot 501 above and the linear welding machine 2, which is convenient for subsequent welding.

[0030] After the barrel 7 is inserted into the limiting column 3, it is buckled on the limiting column 3 through the clamping assembly 6 to prevent the barrel 7 from withdrawing from the limiting column 3, thereby ensuring the accuracy of subsequent welding; at the same time, the upper slider is pressed back into the limiting column 3 through the clamping assembly 6 to ensure that the groove of the barrel 7 corresponds to the welding head of the linear welding machine 2, thereby facilitating subsequent welding.

[0031] Furthermore, a slide groove 302 is provided inside the limit column 3, and the slide groove 302 is located at the lower inside of the limit column 3. The axial direction of the slide groove 302 is the same as the axial direction of the limit column 3. The slide groove 302 is located on the side of the limit column 3 away from the machine base 1. One end of the slide groove 302 is connected to the outside of the limit column 3. The first slot 301 is located in the middle of the slide groove 302, and the first slot 301 is connected to the slide groove 302.

[0032] Furthermore, the upper slider includes an upper slider body 401, a limit plate 402 and a first inclined surface 403, the limit plate 402 is located above the upper slider body 401, the width of the limit plate 402 is the same as the width of the first slot 301, the length of the limit plate 402 is the same as the length of the first slot 301, the height of the limit plate 402 is greater than the depth of the first slot 301, the limit plate 402 is slidably connected to the first slot 301, the first inclined surface 403 is located below the upper slider body 401, and the width of the slide groove 302 is the same as the width of the upper slider body 401.

[0033] Furthermore, the lower slider is an L-shaped structure, and the lower slider includes a lower slider body 404, a second inclined surface 405, a connecting rod 406 and an abutment plate 407, the second inclined surface 405 is located above the lower slider body 404, the first inclined surface 403 and the second inclined surface 405 have the same size, the upper slider body 401 and the lower slider body 404 cooperate through the first inclined surface 403 and the second inclined surface 405, one end of the connecting rod 406 is connected to the lower slider body 404, and the other end of the connecting rod 406 is connected to the abutment plate 407, the abutment plate 407 is close to the side of the limiting column 3 away from the machine base 1, the width of the lower slider body 404 is the same as the width of the slide groove 302, the length of the upper slider body 401 is the same as the length of the lower slider body 404, and the length of the lower slider body 404 is greater than the length of the connecting rod 406.

[0034] Furthermore, a spring 408 is provided at one end of the lower slider body 404 away from the connecting rod 406 , one end of the spring 408 is connected to the inner wall of the slide groove 302 , and the other end of the spring 408 is connected to the lower slider body 404 .

[0035] Through the above technical solution, the width of the upper slider body 401 and the lower slider body 404 is the same as the width of the slide groove 302, and the movement direction of the lower slider body 404 is limited by the slide groove 302, so that the lower slider can only move along the axis direction of the slide groove 302, and the size of the limit plate 402 above the upper slider body 401 is adapted to the size of the first slot 301, and the limit plate 402 is connected to the first slot 301 for sliding up and down, and the upper slider limits the movement direction through the first slot 301. At the same time, since the upper slider body 401 and the lower slider body 404 complete the inclined surface matching through the first inclined surface 403 and the second inclined surface 405, the horizontal movement of the lower slider body 404 is converted into the vertical movement of the upper slider body 401, and then the limit plate 402 can be extended or retracted into the first slot 301, completing the limitation of the circumferential rotation direction of the barrel 7.

[0036] Furthermore, the clamping assembly 6 includes a pressing plate 601 and a pressing rod 602. The pressing plate 601 is hinged to the mounting plate 5. The size of the pressing plate 601 is larger than the cross-sectional size of the barrel 7 along the radial direction. The pressing rod 602 is located on the side of the pressing plate 601 close to the limiting column 3. When the pressing plate 601 abuts against the limiting column 3, the pressing rod 602 extends into the slide groove 302 and abuts against the abutment plate 407.

[0037] Through the above technical solution, such as Figure 2As shown, when the pressing assembly 6 is retracted to the mounting plate 5, under the action of the spring 408, the first inclined surface 403 and the second inclined surface 405 completely overlap, and the abutting plate 407 is at the opening closest to the slide groove 302. At this time, the upper slide block is at the highest point, and the limiting plate 402 extends out of the first slot 301. At this time, it is convenient to insert the barrel 7 along the limiting plate 402 into the limiting column 3, so as to complete the limiting of the barrel 7 in the circumferential direction;

[0038] like Figure 4 As shown, when the clamping assembly 6 is buckled down through the hinge, the pressing plate 601 abuts against the end faces of the limiting column 3 and the barrel 7, the pressing rod 602 extends into the slide groove 302, and the pressing rod 602 abuts against the abutting plate 407. It can be known that the pressing rod 602 will not interfere with the limiting column 3 before extending into the slide groove 302. The abutting plate 407 pushes the lower slider body 404 to move the compression spring 408 toward the machine base 1 through the connecting rod 406; at this time, due to the action of the first inclined surface 403 and the second inclined surface 405, the upper slider body 401 falls under the action of its own weight, the limiting plate 402 is received in the first slot 301, and there is no foreign matter at the welding groove of the barrel 7, which is convenient for subsequent welding. At the same time, since the length of the connecting rod 406 is smaller than the length of the lower slider body 404 and the upper slider body 401, when the lower slider body 404 slides, the upper slider body 401 will not completely fall out of the lower slider body 404, and the first inclined surface 403 and the second inclined surface 405 are always partially in contact with each other, so that after the spring 408 is reset, the upper slider body 401 is pushed up to complete the extension of the limit plate 402.

[0039] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
