Description

Technical Field

[0001] The invention relates to the technical field of metal welding, in particular to a metal product welding device with an anti-splash structure. Background Art

[0002] In the processing and production of metal products, it is often necessary to connect metal products by welding. Laser welding is a commonly used method for welding metal products. Laser welding uses a high-energy-density laser beam as a heat source to rapidly heat the metal material locally to a molten or vaporized state, and then cools and crystallizes to form a strong weld joint.

[0003] When other objects need to be connected to the inside of a metal pipe, it is usually necessary to cut the metal pipe into two halves, connect the objects to be installed, and then weld the two halves of the pipe by laser welding.

[0004] When welding the two halves of a pipe, it is necessary to align the pipes by means of a fixing device, and when the pipe to be welded is too long, it is also necessary to fix the weld by means of a fixing device to avoid a large gap at the weld. Existing devices can fix the pipe by means of a fixing device to facilitate laser welding, but the fixing device cannot move with the welding device and cannot fix the position of the weld in real time, which can easily lead to different degrees of splicing tightness on the metal pipe, resulting in inconsistent welds on the outer surface of the metal pipe, making the weld of the metal pipe unsightly and affecting the strength of the metal pipe during use. Therefore, a metal pipe welding fixing device that can move in real time and prevent splashing is required. Summary of the invention

[0032] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide a metal product welding equipment with an anti-splash structure, including a welding equipment body 1, a welding workbench 2 is fixedly installed on the top of the welding equipment body 1, a movable laser welding assembly 21 is arranged on one side of the top of the workbench 2, a mounting plate 22 is fixedly installed on the top of the workbench 2, a clamping member 23 is installed on the top of the mounting plate 22, a metal pipe 24 is clamped and fixed inside the clamping member 23, a clamping member 25 is arranged at the other end of the metal pipe 24, and the clamping member 23 and the clamping member 25 are used to preliminarily fix and clamp the two ends of the metal pipe 24 to the bottom of the laser welding assembly 21.

[0034] By means of clamping part 1 23 and clamping part 2 25 which can be moved left and right, the two ends of the metal pipe 24 which is divided into two halves of different lengths can be clamped and fixed, so that the joint of the metal pipe 24 is located at the bottom of the laser welding head of the laser welding assembly 21, which is convenient for laser welding of the metal pipe 24.

[0035] It should be noted that the laser welding assembly 21 can move the laser welding head up, down, left and right through the slide rails and slideways installed at the bottom and sides. The internal structure of the laser welding assembly 21 is the existing technology, and its working principle is common knowledge to the staff in this field, and will not be repeated here.

[0036] The outer surface of the metal pipe 24 is sleeved with a fixing sleeve 3, a welding port 31 is provided on the top of the fixing sleeve 3, connecting sleeves 32 are fixedly installed on both sides of the fixing sleeve 3, a fixing block 33 is fixedly installed on the top of the outer surface of the connecting sleeve 32, a leakage hole is provided on the top of the inner wall of the connecting sleeve 32 and penetrates into the interior of the fixing block 33, a clamping block 34 is slidably installed inside the leakage hole, a telescopic component 4 is provided on the top of the clamping block 34, the telescopic component 4 is used to move the clamping block 34 downward to clamp and fix the joint of the metal pipe 24, a connecting component 5 is installed on the outer surface of the fixing sleeve 3, the connecting component 5 connects the fixing sleeve 3 with the laser welding component 21, so that the fixing sleeve 3 can move together with the laser welding component 21.

[0037] By setting the fixing sleeve 3 between the clamping piece 1 23 and the clamping piece 25 in the connecting component 5, one end of the metal pipe 24 is placed in the clamping piece 1 23 for clamping, and it needs to pass through the connecting sleeve 32 and the fixing sleeve 3, and then move to a suitable position through the clamping piece 25 to clamp the other end of the metal pipe 24, so that the laser welding head can extend into the interior of the fixing sleeve 3 through the welding port 31 opened at the top of the fixing sleeve 3, and weld the joint of the metal pipe 24 in the fixing sleeve 3. The fixing sleeve 3 can block the spatter debris generated by welding, and the fixing sleeve 3 can be moved together with the laser welding component 21 through the connecting component 5, so that the fixing sleeve 3 is located outside the laser welding head to block the spatter debris.

[0038] At the same time, connecting sleeves 32 are installed on both sides of the fixing sleeve 3. A clamping block 34 that can be retracted and extended through the telescopic component 4 is arranged inside the connecting sleeve 32. The clamping block 34 can be clamped on the outer surface of the metal pipe 24 to tightly connect the joints of the metal pipe 24 in the fixing sleeve 3, so that the welds of the metal pipe 24 are more beautiful and firm.

[0039] First, considering how to move the fixed sleeve 3 with the laser welding assembly 21, Figure 1 and Figure 3, the specific structure of the moving component is disclosed, the connecting component 5 includes a connecting rod 1 501 fixedly installed on the outer surface of the moving seat of the laser welding component 21, the other end of the connecting rod 1 501 is fixedly installed with a moving plate 502, the bottom of the moving plate 502 is slidably installed in the inside of the slide groove opened on the top of the workbench 2, and the side of the moving plate 502 away from the connecting rod 1 501 is fixedly installed with a connecting rod 2 503, and the other end of the connecting rod 2 503 is fixedly installed on the outer surface of the fixed sleeve 3. When the laser welding component 21 moves, it can drive the fixed sleeve 3 to move together.

[0040] By opening a slide groove on the top of the workbench 2, the movable plate 502 can be installed inside the slide groove for sliding. Behind the movable plate 502 is the laser welding assembly 21. The laser welding assembly 21 moves left and right through a movable seat arranged at the bottom. The movable seat and the movable plate 502 are connected by a connecting rod, so that the movable plate 502 can be moved through the movable seat. At the same time, the other side of the movable seat is connected to the outer surface of the fixed sleeve 3 through the connecting rod 2 503, so that the laser welding assembly 21 is moved to different positions for welding, driving the movable plate 502 and the fixed sleeve 3 to move together, so that the fixed sleeve 3 is always outside the welding head to prevent welding debris from splashing.

[0041] Secondly, considering the problem of how the clamping block 34 in the connecting sleeve 32 clamps and fixes the pipe, Figure 4-Figure 6 , the specific structure of the telescopic component 4 is disclosed, the telescopic component 4 includes a threaded hole opened at the top of the fixed block 33, the bottom of the threaded hole penetrates into the inside of the leak hole, the internal thread of the threaded hole is connected with a threaded column 401, the top of the inner wall of the leak hole is slidably installed with an extrusion plate 402, the bottom of the extrusion plate 402 is connected with a reset spring 403, the bottom end of the reset spring 403 is connected to the top of the clamping block 34, the threaded column 401 rotates and moves downward, the extrusion plate 402, the reset spring 403 and the clamping block 34 are squeezed downward, so that the clamping block 34 clamps the connection of the metal pipe 24.

[0042] There are two telescopic components 4 and clamping blocks 34, which are symmetrically distributed inside the connecting sleeve 32, and clamp and fix the upper and lower joints of the metal pipe 24 divided into two halves. There are two connecting sleeves 32, which are symmetrically distributed on both sides of the fixed sleeve 3, and clamp and fix the metal pipes 24 on both sides of the fixed sleeve 3, so as to facilitate the close splicing of the metal pipes 24 welded in the fixed sleeve 3.

[0043] A threaded hole is formed on the top of the fixing block 33 on the outer surface of the connecting sleeve 32, and an extrusion plate 402 is slidably installed on the top of the inner wall of the leakage hole. The extrusion plate 402 and the clamping block 34 at the bottom of the extrusion plate 402 are connected by a reset spring 403. The threaded column 401 connected to the threaded hole can be screwed to allow the threaded column 401 to pass through the threaded hole into the leakage hole. The extrusion plate 402 is pressed downward so that the extrusion plate 402 squeezes the clamping block 34 downward through the reset spring 403, so that the arc-shaped clamping interface at the bottom of the clamping block 34 is clamped to the outer surface of the metal pipe 24, and the metal pipe 24 divided into two halves is clamped and fixed, so that the splicing gap of the metal pipe 24 in the fixing sleeve 3 is connected more tightly, and the welding of the metal pipe 24 is tighter and stronger.

[0044] Again, considering that the welding part of the metal pipe 24 is covered by the fixing sleeve 3 and the connecting sleeve 32, the welding slag will remain on the outer surface of the metal pipe 24 and needs to be cleaned in time. Figure 4 and Figure 5 The two sides of the clamping block 34 are provided with oblique openings 3401, so that when the connecting sleeve 32 and the fixing sleeve 3 move on the outer surface of the metal pipe 24, the oblique openings 3401 on the clamping block 34 can scrape and clean the residue on the weld of the metal pipe 24.

[0045] There are two movable plates 502 symmetrically arranged on both sides of the fixed sleeve 3 , and a collecting box 6 is slidably installed between the two movable plates 502 . The collecting box 6 moves together with the movable plate 502 to receive and collect the debris scraped off by the clamping block 34 .

[0046] By opening upwardly inclined bevels 3401 on both sides of the clamping block 34, the clamping block 34 is squeezed and clamped on the outer surface of the metal pipe 24 by the extrusion plate 402 through the return spring 403. When the fixed sleeve 3 moves to drive the connecting sleeve 32 and the clamping block 34 to move, the clamping block 34 will not affect the movement of the fixed sleeve 3 on the outer surface of the metal pipe 24 through the expansion and contraction of the return spring 403. In addition, the bevels 3401 opened on the side of the clamping block 34 can scrape off the debris of the welding seam of the metal pipe 24 and the debris remaining on the welding seam. At the same time, the two movable plates 502 can be opened on the workbench 2. The sliding groove Sliding inward, the movable plate 502 close to the laser welding component 21 is connected by the connecting rod 1 501, and the outer surface of the fixed sleeve 3 is connected through the connecting rod 2 503 in the middle of the two movable plates 502. A card slot is opened on the middle inner wall of the two movable plates 502, so that the collecting box 6 can be plugged into the middle of the two movable plates 502 through the card block, so that the collecting box 6 can move together with the fixed sleeve 3. The collecting box 6 is set at the bottom of the fixed sleeve 3, and the welding slag scraped by the clamping block 34 in the connecting sleeve 32 is received and collected, and the collecting box 6 can be pulled out from the middle of the two movable plates 502 to process the collected welding slag.

[0047] Finally, considering how to clamp and fix the two ends of the metal pipe 24, Figure 2 , the specific structures of the clamping member 23 and the clamping member 25 are disclosed. The clamping member 23 includes a pneumatic clamping disk 2301 installed on the top of the mounting plate 22. A driving motor 2302 is arranged on the outside of the pneumatic clamping disk 2301. The driving motor 2302 is used to drive the pneumatic clamping disk 2301 to rotate an angle.

[0048] The second clamping member 25 includes a sliding groove opened on the top of the workbench 2, and a reciprocating screw 2501 is rotatably connected inside the sliding groove. One end of the reciprocating screw 2501 passes through the outside of the workbench 2, and a stepper motor 2502 is arranged on the outside of the workbench 2. A track is sleeved on the rotating shaft of the stepper motor 2502, and the other end of the track is sleeved on the outer surface of the reciprocating screw 2501. The outer surface of the reciprocating screw 2501 is threadedly connected to a moving platform 2503, and a pneumatic clamping disk 2504 is rotatably installed on the outer side of the moving platform 2503.

[0049] A pneumatic clamping disk 2301 is fixedly installed on the top of the mounting plate 22, and a driving motor 2302 is installed on the left side of the pneumatic clamping disk 2301. The output shaft of the driving motor 2302 is connected to the outer side of the pneumatic clamping disk 2301. The rotation of the driving motor 2302 can drive the pneumatic clamping disk 2301 to rotate. A sliding groove is opened on the top of the workbench 2. A reciprocating screw rod 2501 that penetrates the outside of the workbench 2 is rotatably installed inside the sliding groove, so that the stepper motor 2502 can be connected to the reciprocating screw rod 2501 through the track outside the workbench 2, so that the stepper motor 2502 is powered on and rotated, which can drive the reciprocating screw rod 2501 to rotate. The movable platform 2503 threadedly connected to the outer surface of the rod 2501 moves left and right, and the pneumatic clamping plate 2504 is rotatably installed on the outer side surface of the movable platform 2503, so that the pneumatic clamping plate 2504 can be moved left and right through the movable platform 2503, and the distance between the pneumatic clamping plate 2504 and the pneumatic clamping plate 1 2301 is adjusted to clamp and fix metal pipes 24 of different lengths. When the pneumatic clamping plate 1 2301 rotates, it can drive the pneumatic clamping plate 2504 installed on the movable platform 2503 to rotate together, so as to achieve the rotation angle of the clamped metal pipe 24, so as to facilitate the welding of the joint seams of the metal pipe 24.

[0050] It should be noted that the pneumatic clamping plate 1 2301 and the pneumatic clamping plate 2 2504 clamp and fix the metal pipe 24 by driving the clamping block 34 through the cylinder. The internal structure of the pneumatic clamping plate 1 2301 and the pneumatic clamping plate 2 2504 is the existing technology, and its working principle is common knowledge to the staff in this field, and will not be repeated here.

[0051] In summary, the working principle of this solution is as follows:

[0052] When welding the metal pipe 24, the two halves of the spliced ​​metal pipe 24 are inserted into the interior of the pneumatic clamping disk 1 2301, and the other end of the metal pipe 24 passes through the connecting sleeve 32 and the fixing sleeve 3, and then is inserted into the interior of the pneumatic clamping disk 2 2504 adjusted to a suitable position by the reciprocating screw rod 2501 for fixing. The moving seat of the laser welding assembly 21 is connected to the fixing sleeve 3 through the connecting assembly 5, so that when the laser welding assembly 21 moves to one end of the metal pipe 24, the fixing sleeve 3 also moves with the laser welding assembly 21, and the laser welding head is inserted into the welding port 31 opened at the top of the fixing sleeve 3. At this time, the threaded column 401 is twisted to squeeze the extrusion plate 402 and the reset spring 403 in the leak hole, so that the clamping block 34 clamps the metal pipe 24, so that the metal pipe 24 can be clamped more tightly after splicing. The laser welding head drives the fixing sleeve 3 and the connecting sleeve 32 to move on the outer surface of the metal pipe 24 to weld the spliced ​​part of the metal pipe 24;

[0053] During the movement of the connecting sleeve 32, the clamping block 34 can rebound up and down through the reset spring 403, which will not affect the movement of the connecting sleeve 32, and the bevels 3401 on both sides of the clamping block 34 can scrape and clean the welding seams on the metal pipe 24 and scrape off the residual welding slag, making the welding of the metal pipe 24 more beautiful and firm, and the collecting box 6 is always located below the connecting sleeve 32 through the moving plate 502 to receive and collect the scraped debris.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
