Description

Technical Field

[0001] The present invention relates to the technical field of radiator welding, in particular to a welding device for a radiator of engineering machinery. Background Art

[0002] During operation, construction machinery generates a certain amount of heat, so a corresponding construction machinery radiator is provided to dissipate heat for the construction machinery. The construction machinery radiator includes a main pipe and multiple branch pipes welded to the main pipe. The main pipe is used to converge the heat dissipation medium flowing through the multiple branch pipes. The branch pipes and the main pipe are roughly T-shaped, and the annular seam between the branch pipes and the main pipe is roughly annular. In the related art, when welding an annular weld, the welding device first welds the first half of the annular weld, and then welds the second half of the annular weld, thereby completing the welding of the entire annular weld. However, when welding the second half of the annular weld, it is easy to cause the first half that has been welded previously to be reheated, thereby affecting the welding quality of the first half. Therefore, when welding the annular weld, it is necessary to weld the first half and the second half at the same time. When welding the main pipe, it needs to be butt-welded with multiple branch pipes. However, when welding multiple branch pipes with the grab pipe, the main pipe is easily affected by external forces, causing shaking and deflection, which affects the welding effect. Therefore, we proposed a welding device for engineering machinery radiators. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a welding device for a radiator of engineering machinery, comprising a square base, the top of the square base is fixedly connected to a side pressure fixing mechanism, the top of the square base is fixedly connected to a vertical electric slide rail, the inner side of the vertical electric slide rail is slidably connected to an adjustable clamping tube mechanism, both sides of the vertical electric slide rail are fixedly connected to vertical fixing plates, the top of the vertical electric slide rail is fixedly connected to a hanging electric slide rail, the bottom of the hanging electric slide rail is slidably connected to a bottom slide plate, and the bottom of the bottom slide plate is fixedly connected to an electric welding arm; The side pressure fixing mechanism includes a circular concave shell, and the two circular concave shells respectively clamp the ends of the main pipe from both ends to prevent the main pipe from shaking and deflecting due to external forces when the branch pipe is butt-welded to the main pipe, which affects the welding effect. The outer side of the circular concave shell is sleeved and rotatably connected to the annular electric slide rail 1, and the outer side of the annular electric slide rail 1 is fixedly connected to the auxiliary drive assembly; There are two vertical electric slide rails, and the two vertical electric slide rails are respectively distributed on both sides of the side pressure fixing mechanism; there are two electric welding arms, and the two electric welding arms are symmetrically distributed at the bottom of the bottom slide; There are two auxiliary drive assemblies, and the two auxiliary drive assemblies are symmetrically distributed on both sides of the annular electric slide rail, and the bottom of the auxiliary drive assembly is fixedly connected to the top of the square base; The top of the annular electric slide rail is fixedly connected with a correction angle block, and the inner side of the circular concave shell is fixedly connected with an arc-shaped grinding block. By arranging the arc-shaped grinding block on the inner wall of the circular concave shell, the end face of the pre-fixed main pipe is ground flat, so as to prevent the end face of the main pipe from being uneven when being fixed, resulting in an overall tilted state that affects the butt welding effect of the branch pipe. The inner side of the circular concave shell is provided with an arc-shaped through hole. By providing a plurality of arc-shaped through holes on the inner wall of the circular concave shell, it is convenient to discharge the debris generated by grinding in time, so as to prevent the debris generated by grinding from accumulating on the inner wall of the circular concave shell and affecting the fixed clamping effect of the main pipe. The outer side of the circular concave shell is fixedly connected with a correction arc block. By arranging the correction arc block and the correction angle block, the annular welding of the main pipe is in a position facing upward, so as to prevent the annular weld from being difficult to accurately adjust to the position facing upward after the main pipe is rotated and ground, affecting the welding effect.

When the annular electric slide rail is not limited, the threaded sleeve block is driven to rotate and the threaded sleeve block is affected by the threaded cooperation between the threaded sleeve block and the threaded long rod. One side of the annular electric slide rail 2 is fixedly connected with an inclined scraper rod, which scrapes and cleans the top surface of the square base when it moves with the threaded sleeve, preventing excessive welding slag from accumulating on the square base after long-term welding and adhering to its surface when the main pipe rotates, affecting the subsequent welding effect. The inclined surface of the inclined scraper rod is set to make the pushed welding slag move toward the fixed angle plate, preventing a part of the pushed welding slag from always accumulating near the position of the side of the vertical electric slide rail and being difficult to handle. The side of the side-connected square plate away from the annular electric slide rail 2 is fixedly connected to the outer side of the annular electric slide rail 1, and the bottom of the fixed angle plate is fixedly connected to the top of the square base.

The outer side of the annular sleeve block is fixedly connected to an external angle plate, and the top of the external angle plate passes through and is fixedly connected to a fixed through rod, and the outer side of the fixed through rod is sleeved and slidably connected to a curved pressure plate, and the inner side of the curved pressure plate is fixedly connected to a reset spring, and the extension force of the reset spring pushes the curved pressure plate to tightly contact with the inner wall of the rectangular through hole to adjust the annular The branch pipe in the sleeve block is fixed in position to prevent the branch pipe from being relatively offset from the annular weld by external force during the branch pipe welding operation, which affects the welding effect. The telescopic pushing fixation of the two curved pressure plates and the return spring facilitates the disassembly and installation of the adjustable pipe clamping mechanism, and prevents the branch pipe from being difficult to adapt and adjust to complete the welding process when the number of branch pipes to be welded to the main pipe changes. One side of the inner sliding long plate is slidably connected to the inner side of the vertical electric slide rail. There are multiple annular sleeve blocks, and the multiple annular sleeve blocks are distributed on the inner wall of the rectangular through hole. There are multiple external angle plates, and the multiple external angle plates are symmetrically distributed on the outside of the annular sleeve block. There are multiple curved pressure plates, and the multiple curved pressure plates are symmetrically distributed at both ends of the return spring.

[0006] The present invention provides a welding device for a radiator of engineering machinery. It has the following beneficial effects: 1. This welding device for engineering machinery radiators has two circular concave shells that clamp the ends of the main pipe from both ends to prevent the main pipe from shaking and deflecting due to external forces during the butt welding operation of the branch pipe, which affects the welding effect. The arc-shaped brush cleans the outer surface of the threaded long rod as the threaded sleeve moves, preventing dust and welding slag from adhering to the outer surface of the threaded long rod and affecting the threaded fit between the threaded sleeve and the threaded long rod. The position of the branch pipe is adjusted to adapt to different docking positions through the sliding fit between the annular sleeve and the rectangular through hole, preventing the branch pipe from being difficult to adapt to the welding process when the annular welding docking position of the main pipe changes.

[0007] 2. The welding device for the engineering machinery radiator is provided with a side pressure fixing mechanism. By arranging an arc-shaped grinding block on the inner wall of the circular concave shell, the end face of the pre-fixed main pipe is polished flat, so as to prevent the uneven end face of the main pipe from being tilted as a whole during fixation, which affects the butt welding effect of the branch pipe. By opening a plurality of arc-shaped through holes on the inner wall of the circular concave shell, it is convenient for the timely discharge of the debris generated by grinding, so as to prevent the debris generated by grinding from accumulating on the inner wall of the circular concave shell and affecting the fixing and clamping effect of the main pipe. By arranging the correction arc block and the correction angle block, the annular welding of the main pipe is placed in a position facing upward, so as to prevent the difficulty in accurately adjusting the annular weld to a position facing upward after the main pipe is rotationally polished, which affects the welding effect. The two circular concave shells respectively perform internal clamping on the end of the main pipe from both ends of the main pipe, so as to prevent the main pipe from shaking and deflecting due to external forces during the butt welding operation of the branch pipe, which affects the welding effect.

The welding device for the radiator of engineering machinery is provided with an auxiliary driving component, and the arc-shaped brush cleans the outer surface of the threaded long rod as the threaded sleeve moves, preventing dust and welding slag from adhering to the outer surface of the threaded long rod and affecting the thread matching effect of the threaded sleeve and the threaded long rod. By arranging side connecting square plates on both sides of the annular electric slide rail one, the annular electric slide rail two is limited in rotation to prevent the annular electric slide rail two from rotating when the threaded sleeve is driven to rotate due to the thread matching effect of the threaded sleeve and the threaded long rod. The inclined scraper moves with the threaded sleeve to scrape and clean the top surface of the square base to prevent excessive welding slag from accumulating on the square base after long-term welding and adhering to its surface when the main pipe rotates, affecting the subsequent welding effect. The inclined surface of the inclined scraper rod is set to make the pushed welding slag move toward the fixed angle plate, preventing a part of the pushed welding slag from always accumulating near the side of the vertical electric slide rail and being difficult to handle.

[0009] 4. The welding device for engineering machinery radiators is provided with an adjustable pipe clamping mechanism, which realizes the adjustment of the branch pipe position to adapt to different docking positions through the sliding cooperation between the annular sleeve block and the rectangular through-hole, thereby preventing the branch pipe from being difficult to adapt to the welding process when the annular welding docking position of the main pipe changes. The extension force of the reset spring pushes the curved pressure plate to tightly contact the inner wall of the rectangular through-hole to fix the position of the branch pipe in the annular sleeve block, thereby preventing the branch pipe from being relatively offset from the annular weld by external force during the branch pipe welding operation, thereby affecting the welding effect. The telescopic pushing fixation of the two curved pressure plates and the reset spring facilitates the disassembly and installation of the adjustable pipe clamping mechanism, thereby preventing the branch pipe from being difficult to adapt to the welding process when the number of branch pipes to be welded to the main pipe changes.

The auxiliary drive assembly 203 includes a threaded long rod 2031, both ends of the threaded long rod 2031 are fixedly connected to a fixed angle plate 2032, the outer side of the threaded long rod 2031 is sleeved and threadedly connected to a threaded sleeve block 2033, both sides of the threaded sleeve block 2033 are fixedly connected to an arc-shaped brush 2034, the outer side of the threaded sleeve block 2033 is sleeved and rotatably connected to an annular electric slide rail 2035, the outer side of the annular electric slide rail 2035 is fixedly connected to a side connecting square plate 2036, one side of the annular electric slide rail 2035 is fixedly connected to an inclined scraper rod 2037, the side connecting square plate 2036 is fixedly connected to the outer side of the annular electric slide rail 1 202 on the side away from the annular electric slide rail 2035, the bottom of the fixed angle plate 2032 is fixedly connected to the top of the square base 1, and a plurality of threaded sleeve blocks 2033 are provided, and the plurality of threaded sleeve blocks 2033 are symmetrically distributed on the threaded long rod. There are multiple arc-shaped brushes 2034 on the rod 2031, and the multiple arc-shaped brushes 2034 are distributed on both sides of the threaded sleeve 2033. When in use, the main pipe is placed in the middle of the side pressure fixing mechanism 2 and aligned with the vertical electric slide rail 3. The main pipe is then clamped and fixed by the side pressure fixing mechanism 2. After the fixation is completed, the adjustable pipe clamping mechanism 4 is adjusted to a position aligned with the main pipe welding, and the branch pipes are inserted into the adjustable pipe clamping mechanism 4 in sequence. The bottom slide 7 is then driven by the hanging electric slide rail 6 to move and drive the two electric welding arms 8 at the bottom to move together. When the electric welding arms 8 move, the first half and the second half of the annular weld can be welded at the same time. After the welding is completed, the adjustable pipe clamping mechanism 4 is driven by the vertical electric slide rail 3 to move up to the top of the branch pipe. At the same time, the main pipe can be removed as a whole by releasing the fixation of the main pipe by the side pressure fixing mechanism 2. The main pipe is placed between the two circular concave shells 201, and the two annular electric slide rails 202 are driven to move toward each other by the auxiliary drive component 203. When the annular electric slide rail 202 moves, the inner circular concave shell 201 is driven to move. The circular concave shell 201 moves toward one end of the main pipe so that one end of the main pipe is inserted into the circular concave shell 201. When one end of the main pipe contacts the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the main pipe can be manually rotated so that the end face of the main pipe is in friction contact with the arc-shaped grinding block 205. By arranging the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the end face of the pre-fixed main pipe is polished and smoothed. The debris polished off by the arc-shaped grinding block 205 will be promptly removed from the arc-shaped passage opened on the inner wall of the circular concave shell 201. The chips are discharged outward from the hole 206, and a plurality of arc-shaped through holes 206 are opened on the inner wall of the circular concave shell 201 to facilitate timely discharge of the chips generated by grinding. After the end face of the main pipe is ground, the circular concave shell 201 is driven to rotate by the annular electric slide 202. The rotation of the circular concave shell 201 drives the outer correction arc block 207 to rotate until the correction arc block 207 rotates to coincide with the correction angle block 204 on the outer side of the annular electric slide 202 and stops. At this time, the annular weld of the main pipe is in a position facing upward. The setting of the correction arc block 207 and the correction angle block 204 makes the annular weld of the main pipe in a position facing upward. After the correction is completed, the circular concave shell 201 is driven again to the main pipe direction by the auxiliary drive component 203. When the threaded sleeve 2033 is threadedly engaged with the threaded long rod 2031, the outer annular electric slide rail 2035 and the arc-shaped brushes 2034 on both sides are driven to move together. When the threaded sleeve 2033 moves, the arc-shaped brushes 2034 clean the outer surface of the threaded long rod 2031. When the annular electric slide rail 2035 moves, it drives the outer side connecting square plate 2036 and the inclined scraper 2037 on one side together. When the side-connected square plate 2036 moves, it drives the annular electric slide rail 202 on one side to move, so that the circular concave shell 201 can fix the end of the main pipe by side-pushing. By setting the side-connected square plates 2036 on both sides of the annular electric slide rail 202, the annular electric slide rail 2 2035 can be rotationally limited. When the inclined scraper rod 2037 moves together with the threaded sleeve 2033, the top surface of the square base 1 is scraped and cleaned. When the inclined scraper rod 2037 moves toward the vertical electric slide rail 3 square as the threaded sleeve 2033 moves, it pushes a part of the welding slag along its inclined surface to the position of the fixed angle plate 2032. The inclined surface setting of the inclined scraper rod 2037 makes the pushed welding slag move toward the fixed angle plate 2032.

[0014] See also Figures 1-8The present invention provides a welding device for a radiator of engineering machinery: an adjustable pipe clamping mechanism 4 comprises an inner sliding long plate 401, a rectangular through hole 402 is opened on one side of the inner sliding long plate 401, an annular sleeve 403 is slidably connected to the inner wall of the rectangular through hole 402, an outer side of the annular sleeve 403 is fixedly connected to an outer angle plate 404, a top of the outer angle plate 404 passes through and is fixedly connected to a fixed through rod 405, a curved pressure plate 406 is sleeved on the outer side of the fixed through rod 405 and is slidably connected, a return spring 407 is fixedly connected to the inner side of the curved pressure plate 406, and a side of the inner sliding long plate 401 is fixedly connected to the inner wall of the rectangular through hole 402. The side is slidably connected to the inner side of the vertical electric slide rail 3, and multiple annular sleeve blocks 403 are provided, and multiple annular sleeve blocks 403 are distributed on the inner wall of the rectangular through hole 402, multiple external angle plates 404 are provided, and multiple external angle plates 404 are symmetrically distributed on the outside of the annular sleeve block 403, multiple curved pressure plates 406 are provided, and multiple curved pressure plates 406 are symmetrically distributed at both ends of the reset spring 407. When in use, after the main pipe is fixed, the branch pipe is inserted into the annular sleeve block 403, and the branch pipe is moved to a position aligned with the annular weld of the main pipe by moving the annular sleeve block 403. The sliding fit between the block 403 and the rectangular through hole 402 realizes the adjustment of the branch position to adapt to different docking positions, and then pushes the two curved pressure plates 406 toward each other to compress the return spring 407, and at the same time rotates the two curved pressure plates 406 into the rectangular through hole 402. At this time, the return spring 407 applies a pushing force to the top and bottom curved pressure plates 406 through the extension force, so that the curved pressure plates 406 are pushed and fixed in the rectangular through hole 402, and the extension force of the return spring 407 pushes the curved pressure plates 406 to be in close contact with the inner wall of the rectangular through hole 402 To fix the position of the branch pipe in the annular sleeve block 403, after the main pipe and the branch pipe are welded, the vertical electric slide rail 3 drives the inner sliding long plate 401 to move up to the top of the branch pipe to release the clamping restriction of the branch pipe, press the two curved pressure plates 406 to move toward each other and compress the return spring 407, and at the same time, rotate the curved pressure plate 406 around the fixed through rod 405 out of the rectangular through hole 402 to remove the annular sleeve block 403 from the rectangular through hole 402. The telescopic pushing fixation of the two curved pressure plates 406 and the return spring 407 facilitates the disassembly and installation of the adjustable pipe clamping mechanism 4.

[0015] When the present invention is operated, the main pipe is placed in the middle of the side pressure fixing mechanism 2 so that both ends are aligned with the vertical electric slide rail 3. Then, the side pressure fixing mechanism 2 is used to push and clamp the main pipe. After the fixing is completed, the adjustable pipe clamping mechanism 4 is adjusted to a position aligned with the main pipe welding, and the branch pipes are inserted into the adjustable pipe clamping mechanism 4 in sequence. Then, the bottom slide 7 is driven by the hanging electric slide rail 6 to move and drive the two electric welding arms 8 at the bottom to move together. When the electric welding arms 8 move, the first half and the second half of the annular weld can be welded at the same time. After the welding is completed, the adjustable pipe clamping mechanism 4 is driven by the vertical electric slide rail 3 to move up to the top of the branch pipe. At the same time, the main pipe is released by the side pressure fixing mechanism 2 to remove the main pipe as a whole. The main pipe is placed between the two circular concave shells 201, and the two annular electric slide rails 202 are driven to move toward each other by the auxiliary drive component 203. When the annular electric slide rail 202 moves, the inner circular concave shell 201 is driven to move. The circular concave shell 201 moves toward one end of the main pipe so that one end of the main pipe is inserted into the circular concave shell 201. When one end of the main pipe contacts the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the main pipe can be manually rotated so that the end face of the main pipe is in friction contact with the arc-shaped grinding block 205. By arranging the arc-shaped grinding block 205 on the inner wall of the circular concave shell 201, the end face of the pre-fixed main pipe is polished and smoothed. The debris polished by the arc-shaped grinding block 205 will be discharged to the outside in time from the arc-shaped through hole 206 opened on the inner wall of the circular concave shell 201. A plurality of arc-shaped through holes 206 are provided on the inner wall of the circular concave shell 201 to facilitate timely discharge of the debris generated by grinding. After the end face of the main pipe is ground, the circular concave shell 201 is driven to rotate by the annular electric slide 202. The rotation of the circular concave shell 201 drives the outer correction arc block 207 to rotate until the correction arc block 207 rotates to coincide with the correction angle block 204 on the outer side of the annular electric slide 202 and stops. At this time, the annular weld of the main pipe is in a position facing upward. The setting of the correction arc block 207 and the correction angle block 204 makes the annular weld of the main pipe in a position facing upward. After the correction is completed, the circular concave shell 201 is driven again to move toward the main pipe by the auxiliary drive component 203. The two circular concave shells 201 respectively perform correction on the end of the main pipe from both ends of the main pipe. When the in-row clamping fixation is required, when the end of the main pipe needs to be pushed and fixed sideways by the circular concave shell 201, the annular electric slide rail 2035 drives the threaded sleeve 2033 to rotate to cooperate with the threaded long rod 2031. When the threaded sleeve 2033 and the threaded long rod 2031 are threaded together, the outer annular electric slide rail 2035 and the arc-shaped brushes 2034 on both sides move together. The arc-shaped brushes 2034 clean the outer surface of the threaded long rod 2031 as the threaded sleeve 2033 moves. When the annular electric slide rail 2035 moves, it drives the outer side connecting square plate 2036 and the inclined scraper 2037 on one side to move together. When the side connecting square plate 2036 moves, it drives the annular electric slide rail 1 202 on one side to move so that the circular concave shell 201 is The end of the main pipe is fixed by side push, and the rotation of the annular electric slide rail 2035 is limited by setting side connecting square plates 2036 on both sides of the annular electric slide rail 1 202. The inclined scraper 2037 moves with the threaded sleeve 2033 to scrape and clean the top surface of the square base 1. When the threaded sleeve 2033 moves toward the vertical electric slide rail 3, the inclined scraper 2037 pushes a part of the welding slag along its inclined surface to the position of the fixed angle plate 2032. The inclined surface of the inclined scraper 2037 is set to make the pushed welding slag move toward the fixed angle plate 2032. After the main pipe is fixed, the branch pipe is inserted into the annular sleeve block 403. By moving the annular sleeve block 403, the branch pipe is driven to move to a position aligned with the annular weld of the main pipe.The position of the branch pipe is adjusted to adapt to different docking positions by sliding cooperation between the annular sleeve 403 and the rectangular through hole 402, and then the two curved pressure plates 406 are pushed toward each other to compress the return spring 407, and at the same time, the two curved pressure plates 406 are rotated into the rectangular through hole 402. At this time, the return spring 407 applies a pushing force to the top and bottom curved pressure plates 406 through the extension force, so that the curved pressure plates 406 are pushed and fixed in the rectangular through hole 402, and the extension force of the return spring 407 pushes the curved pressure plates 406 to be tightly attached to the inner wall of the rectangular through hole 402 The contact is used to fix the position of the branch pipe in the annular sleeve 403. After the main pipe and the branch pipe are welded, the vertical electric slide 3 drives the inner sliding plate 401 to move up to the top of the branch pipe to release the clamping restriction of the branch pipe. The two curved pressure plates 406 are pressed toward each other and compress the return spring 407. At the same time, the curved pressure plate 406 is rotated around the fixed through rod 405 and out of the rectangular through hole 402. The annular sleeve 403 can be removed from the rectangular through hole 402. The telescopic push-type fixation of the two curved pressure plates 406 and the return spring 407 facilitates the disassembly and installation of the adjustable pipe clamping mechanism 4.
