Description

Technical Field

[0001] The invention belongs to the technical field of welding, in particular to a gas valve production welding device. Background Art

[0002] A gas valve is a device used to control the flow of gas. Its core function is to open or close the valve through the movement of the valve core, thereby achieving precise control of gas flow and pressure. Since the gas valve needs to control the flow of fluid, during the gas valve production process, it is often necessary to weld two pipes together to form a continuous fluid channel to ensure that the fluid can pass through the gas valve smoothly.

[0003] The patent with announcement number CN220943811U discloses a marine low-speed engine valve welding device, which relates to the technical field of marine low-speed engines, including: a workbench, a work plate welded on the top of the workbench, a clamping cylinder movably inserted on the front surface of the work plate, a servo motor fixedly inserted on the back surface of the work plate, and the output end of the servo motor is fixedly connected to the outer wall of the clamping cylinder, and four first electric telescopic rods are movably inserted on the inner wall of the clamping cylinder to allow the valve body and the pipeline to fit together, and then the welding gun is moved to the top of the fitting point of the valve body and the pipeline by the lifting motor and the cylinder, and the welding gun can be opened to weld the valve body. During welding, the servo motor can be started to drive the clamping cylinder to rotate at a uniform speed, thereby driving the pipeline and the valve body to rotate at a uniform speed, so as to achieve the effect of uniform welding of the pipeline and the valve body. At the same time, mechanical rotation replaces manual rotation, which can reduce errors, improve the success rate of welding, and the quality of the finished product.

[0004] However, the above technical solution still has the following deficiencies in practical application: During the welding process, due to the influence of multiple factors, a lot of welding slag may be attached to the weld, for example, improper welding operation or too small welding current.

[0017] The beneficial effects of the present invention are as follows: 1.

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.

[0023] Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a gas valve production welding device, comprising a welding table 1, a frame body 2 is fixedly connected to the middle of the rear side of the upper end surface of the welding table 1, two slide bars 29 are slidably connected to the middle of the frame body 2, and a welding gun 27 is fixedly connected to the front end of the slide bar 29, and an adjustment plate 5 is slidably connected to the middle of the left and right sides of the upper end surface of the welding table 1, and a rotating frame 10 is rotatably provided at one end of the upper side of the adjustment plate 5, and an adjustment disk 11 is fixedly connected to one end of the rotating frame 10, and a plurality of clamping blocks 12 are slidably connected to the adjusting disk 11, and a close-fitting anti-splash slag knocking mechanism for knocking off the welding slag at the weld is provided on the welding table 1; The tightly fitting anti-splash and slag knocking mechanism includes a fixed plate 21 slidably connected to the middle part of the front side of the upper end face of the welding platform 1, two sliding rods 17 are slidably connected to one end of the upper side of the fixed plate 21, and a reciprocating plate 16 is fixedly connected to the rear end of the sliding rod 17, and spring dampers 45 are fixedly connected to the upper and lower sides of the rear end face of the reciprocating plate 16, and the piston end of the spring damper 45 is fixedly connected to a fixed block 46, and a knocking block 30 is fixedly connected to the middle part of the rear end face of the fixed block 46, and a support plate 31 is slidably connected to the middle part of the left and right sides of the upper end face of the welding platform 1, and a fixing ring 32 is fixedly connected to one side of the upper end of the support plate 31, and a plurality of limiting rods 39 are slidably connected to the fixing ring 32, and one end of the limiting rod 39 is fixedly connected to a clamping plate 35, and a sponge ring 34 is installed on one side of the clamping plate 35 through bolts.

[0024] In this embodiment, Figure 3 and Figure 4 As shown, a threaded rod 13 is rotatably provided in the middle of one side of the adjusting disk 11, and the threaded rod 13 is threadedly connected with a threaded block 15, and a plurality of connecting rods 14 are rotatably provided on the threaded block 15, and one end of the connecting rod 14 is rotatably connected with one end of the clamping block 12; The lower end of the adjustment plate 5 is threadedly connected with a threaded rod 8, both ends of the threaded rod 8 are rotatably arranged on the welding table 1, and the middle parts of the left and right sides of the upper end surface of the welding table 1 are fixedly connected with a motor 3 7, and the output end of the motor 3 7 is fixedly connected to one end of the threaded rod 8; Specifically, the ends of the two pipes to be welded are placed on the adjusting disks 11 on both sides and fit with the end faces of one side of the adjusting disks 11, and then the threaded rod 2 13 is manually rotated to make the threaded block 15 move laterally. When the threaded block 15 moves laterally, the connecting rod 2 14 drives the multiple clamping blocks 12 to move radially at the same time until they contact with the outer wall of the pipe, so that the pipe can be clamped. Then, the motors 3 7 on both sides are started. Under the action of the rotation of the threaded rod 1 8, the adjusting plates 5 on both sides slide until the welding points of the two pipes fit together and are aligned with the welding gun 27, and then welding can be carried out. This can achieve the effect of clamping and positioning pipes of different diameters, ensuring stability during the welding process. Moreover, after the pipes are clamped, the pipes on both sides can be driven to move horizontally so that the two pipe ends can be aligned with the welding gun 27, thereby ensuring the accuracy of the welding process.

A connecting rod 4 19 is rotatably set on one side of the upper end of the fixed plate 21, and a connecting rod 3 18 is rotatably set on one end of the connecting rod 4 19. The rear end of the connecting rod 3 18 is rotatably connected to the reciprocating plate 16. A motor 4 20 is fixedly connected to the left side of the upper end of the fixed plate 21, and the output end of the motor 4 20 is fixedly connected to one end of the connecting rod 4 19; An electric push rod 28 is fixedly connected to the middle of the rear end surface of the frame 2, and the piston end of the electric push rod 28 is fixedly connected to the welding gun 27; The two sides of the abutting plate 1 35 are respectively fixedly connected with a second abutting plate 36 and a third abutting plate 37, and the second abutting plate 36 and the third abutting plate 37 are plugged and slidably connected; The lower end of the support plate 31 is threadedly connected with a bidirectional threaded rod 4, both ends of the bidirectional threaded rod 4 are rotatably arranged on the welding table 1, and a motor 3 is fixedly connected to the middle of the left side of the upper end surface of the welding table 1, and the output end of the motor 3 is fixedly connected to the left end of the bidirectional threaded rod 4; A plurality of connecting rods 9 and gears 43 are rotatably provided on one side of the fixed ring 32, the connecting rod 9 is fixedly connected to the gear 43, a connecting rod 5 44 is rotatably provided on one end of the connecting rod 9, one end of the connecting rod 5 44 is rotatably connected to one end of the limit rod 39, a rotating ring 38 is sleeved and rotatably provided on the outer side of the fixed ring 32, a connecting block 41 is fixedly connected to one side of the rotating ring 38, a gear ring 40 is fixedly connected to one side of the connecting block 41, the gear block inside the gear ring 40 is meshed with the gear 43, a motor 6 42 is fixedly connected to one side of the fixed ring 32, and the output end of the motor 6 42 is fixedly connected to one end of the connecting rod 9; A collecting box 33 is fixedly connected to one side of the upper end of the support plate 31, two slide rods 25 are slidably connected to the front side of the upper end of the frame 2, and a scraper 26 is fixedly connected to the lower end of the slide rod 25. An electric push rod 24 is fixedly connected to the front side of the upper end of the frame 2, and the piston end of the electric push rod 24 is fixedly connected to the middle part of the upper end surface of the scraper 26; Specifically, a gas valve is a device for controlling the flow of gas. Its core function is to open or close the valve through the movement of the valve core, thereby achieving precise control of the gas flow and pressure. Since the gas valve needs to control the flow of fluid, it is often necessary to weld two pipes together to form a continuous fluid channel during the production of the gas valve to ensure that the fluid can pass through the gas valve smoothly. When the existing gas valve production welding device is used, during the welding process, it may be affected by multiple factors, which may cause a lot of welding slag to be attached to the weld. For example, improper welding operation or too small welding current, when welding slag is attached to the weld, it not only affects the appearance quality of the weld, but also may hinder subsequent rust removal, anti-corrosion and other treatments. Therefore, in order to solve the above problems, when the embodiment is used, after the ends of the two pipes are aligned and aimed at the welding gun 27, the electric push rod 28 can be started to drive the welding gun 27 to move horizontally according to the diameter of the pipe, so that the welding gun 27 is close to the pipe to a suitable position, and then the welding gun 27 and the motor 26 are turned on at the same time, and the motors 26 on both sides drive the rotating frame 10 to rotate, so that the pipes on both sides can be rotated at the same time, so that the welding gun 27 can weld the whole circle of the joint of the two pipes; After the two pipes are welded together, the welding gun 27 is closed, and then the motor 5 22 is used to drive the threaded rod 3 23 to rotate, so that the knocking block 30 is close to the weld. At the same time, the motor 4 20 drives the connecting rod 4 19 to rotate, and the connecting rod 3 18 rotates, so that the reciprocating plate 16 can form a back-and-forth reciprocating movement. At the same time, the knocking block 30 moves back and forth to knock the weld. In addition, under the action of the spring damper 45, a buffering effect can be provided to prevent the pipe from being deformed due to knocking. At the same time, with the rotation of the pipe, the welding slag around the pipe weld can be knocked off, thereby ensuring the appearance quality of the weld. At the same time, it also avoids the smooth progress of subsequent rust removal, anti-corrosion and other treatments due to the presence of welding slag at the weld. When the knocking block 30 knocks the welding slag, welding slag splashing will occur. When the welding slag splashes to the position of the pipeline other than the weld, it will affect the appearance quality of the rest of the pipeline surface. Moreover, when the welding slag is too dispersed, it is more difficult to clean up. Therefore, while the knocking work is in progress, the motor 3 can be started to drive the bidirectional threaded rod 4 to rotate, so that the support plates 31 on both sides can slide in different directions at the same time, so that the sponge ring 34 is close to the weld. Moreover, under the premise of not affecting the normal operation of the knocking block 30, the sponge ring 34 is made as close to the weld as possible, and then the motor 6 42 is started to drive the connecting rod 9 and the gear 43 on one side to rotate, so that the ring gear 40 and the rotating ring 38 can rotate at the same time. When the ring gear 40 rotates, multiple connecting rods 9 and gears 43 can rotate at the same time. When the angle between the connecting rod 1 9 and the connecting rod 5 44 changes, the limiting rod 39 can slide on the fixing ring 32, so that the plurality of abutting plates 1 35 move radially. At the same time, the abutting plates 2 36 and the abutting plates 3 37 can also slide relatively. When the plurality of abutting plates 1 35, 2 36 and 37 move radially at the same time and approach the pipeline, the sponge ring 34 can be pressed against the pipeline surface by squeezing. At this time, under the action of the two sponge rings 34, the weld is separated from the rest of the pipeline, and the welding slag splashed during the knocking process will be intercepted by the sponge ring 34 and attached to the sponge ring 34, thereby effectively preventing the welding slag from splashing to the pipeline surface area other than the weld during the knocking process, thereby ensuring the appearance quality of the rest of the pipeline. When the welding slag at the pipe weld is knocked off, the above-mentioned components are driven to reset and the pipe can be removed. Since the sponge ring 34 intercepts the welding slag, the intercepting surface of the sponge ring 34 will also be attached with welding slag. In subsequent use, the welding slag attached to the surface of the sponge ring 34 may fall to the welding seam again, thereby affecting the welding quality. Therefore, when the sponge ring 34 is restored, the support plates 31 on both sides are driven away from each other until the end surfaces of the two sponge rings 34 close to each other are flush with the left and right edges of the scraper 26 respectively, and then the electric push rod 24 is used to drive the scraper 26 to descend, so that the edge of the scraper 26 and the end surfaces of the sponge ring 34 close to each other can form a scraping, so as to scrape the welding slag remaining on the surface of the sponge ring 34 into the collection box 33, thereby realizing the self-cleaning of the residual welding slag on the surface of the sponge ring 34, avoiding the situation that the welding slag falls to the welding seam through the sponge ring 34 during subsequent use, thereby affecting the welding quality; Therefore, by utilizing the tightly fitting anti-splash slag knocking mechanism, after the two pipes are welded together, the welding slag around the pipe weld can be knocked off by knocking, thereby ensuring the appearance quality of the weld. At the same time, it also avoids the smooth progress of subsequent rust removal, anti-corrosion and other treatments due to the welding slag on the weld. In addition, during the slag knocking process, multiple clamping plates 1 35, 36 and 37 can be driven to move radially at the same time, and the sponge ring 34 can be pressed against the pipe surface by extrusion. Under the action of the two sponge rings 34, the weld is separated from the rest of the pipe, and the welding slag splashed during the slag knocking process will be intercepted by the sponge ring 34 and It is attached to the sponge ring 34, thereby effectively preventing the welding slag from splashing to the pipe surface area other than the weld during the knocking-off process, thereby ensuring the appearance quality of the remaining positions of the pipe, and when the welding slag at the pipe weld is knocked off and the pipe is removed, the two sponge rings 34 are driven to reset and move to a suitable spacing, driving the scraper 26 to descend, so that the edge of the scraper 26 and the end surface of the sponge ring 34 close to each other form a scraping, so as to scrape the welding slag remaining on the surface of the sponge ring 34 into the collection box 33, thereby realizing self-cleaning of the residual welding slag on the surface of the sponge ring 34, and avoiding the situation in which the welding slag falls to the weld through the sponge ring 34 during subsequent use, thereby affecting the welding quality.

[0026] Working principle: place the two ends of the pipes to be welded on the adjusting disks 11 on both sides, and fit them with the end faces of one side of the adjusting disks 11, then manually rotate the threaded rod 2 13 to make the threaded block 15 move horizontally, when the threaded block 15 moves horizontally, the connecting rod 2 14 drives multiple clamping blocks 12 to move radially at the same time until they contact the outer wall of the pipe, so that the pipe can be clamped, and then start the motors 3 7 on both sides, under the action of the rotation of the threaded rod 1 8, the adjustment plates 5 on both sides slide until the welding points of the two pipes fit together and align with the welding gun 27, then the welding work can be carried out, when the ends of the two pipes are aligned and aligned with the welding gun 27, the electric push rod 28 can be started according to the diameter of the pipe to drive the welding gun 27 to move horizontally, so that the welding gun 27 is close to the pipe to a suitable position, and then the welding gun 27 and the motor 2 6 are turned on at the same time, and the motors 26 on both sides drive the rotating frame 10 to rotate When the two pipes are welded together, the welding gun 27 is turned off, and then the motor 5 22 is used to drive the threaded rod 3 23 to rotate, so that the knocking block 30 is close to the weld. At the same time, the motor 4 20 drives the connecting rod 4 19 to rotate, and the connecting rod 3 18 rotates, so that the reciprocating plate 16 can be reciprocated back and forth. At the same time, the knocking block 30 moves back and forth to knock the weld. In addition, under the action of the spring damper 45, a buffering effect can be provided to prevent the pipe from being deformed due to knocking. At the same time, with the rotation of the pipe, the welding slag around the pipe weld can be knocked off, thereby ensuring the appearance quality of the weld. At the same time, it is also avoided that the welding slag at the weld affects the smooth progress of subsequent rust removal, anti-corrosion and other treatments.When the knocking block 30 knocks the welding slag, welding slag splashes. When the welding slag splashes to the position of the pipeline other than the weld, it will affect the appearance quality of the rest of the pipeline surface. Moreover, when the welding slag is too dispersed, it is also difficult to clean up. Therefore, while the knocking work is in progress, the motor 1 3 can be started to drive the bidirectional threaded rod 4 to rotate, so that the support plates 31 on both sides can slide in different directions at the same time, so that the sponge ring 34 is close to the weld. Moreover, without affecting the normal operation of the knocking block 30, the sponge ring 34 is made as close to the weld as possible, and then the motor 6 42 is started to drive the connecting rod on one side. When the gear ring 40 rotates, the connecting rods 19 and the gear 43 rotate, so that the gear ring 40 and the rotating ring 38 rotate at the same time. When the gear ring 40 rotates, the multiple connecting rods 19 and the gear 43 rotate at the same time. When the angle between the connecting rod 19 and the connecting rod 5 44 changes, the limiting rod 39 can slide on the fixed ring 32, so that the multiple clamping plates 1 35 move radially. At the same time, the clamping plates 2 36 and the clamping plates 3 37 can also slide relatively. When the multiple clamping plates 1 35, 2 36, and 37 move radially at the same time and approach the pipeline, the sponge ring 34 will be pressed against the pipeline surface by squeezing. At this time, between the two sea The sponge ring 34 can be used to separate the weld from the rest of the pipe, and the weld slag splashed during the knocking process will be intercepted by the sponge ring 34 and attached to the sponge ring 34, thereby effectively preventing the weld slag from splashing to the pipe surface area other than the weld during the knocking process, thereby ensuring the appearance quality of the rest of the pipe. When the weld slag at the pipe weld is knocked off, the above-mentioned components are driven to reset and the pipe can be removed. Since the sponge ring 34 intercepts the weld slag, the intercepting surface of the sponge ring 34 will also be attached with weld slag. In subsequent use, the weld slag attached to the surface of the sponge ring 34 may fall to the weld again. Therefore, when the sponge ring 34 is restored, the support plates 31 on both sides are driven away from each other until the end faces of the two sponge rings 34 close to each other are flush with the left and right edges of the scraper 26 respectively, and then the electric push rod 24 is used to drive the scraper 26 to descend, so that the edge of the scraper 26 and the end faces of the sponge ring 34 close to each other can form a scraping, so as to scrape the residual welding slag on the surface of the sponge ring 34 into the collection box 33, thereby realizing the self-cleaning of the residual welding slag on the surface of the sponge ring 34, avoiding the situation that the welding slag falls to the weld through the sponge ring 34 during subsequent use, thereby affecting the welding quality;Therefore, by utilizing the tightly fitting anti-splash slag knocking mechanism, after the two pipes are welded together, the welding slag around the pipe weld can be knocked off by knocking, thereby ensuring the appearance quality of the weld. At the same time, it also avoids the smooth progress of subsequent rust removal, anti-corrosion and other treatments due to the welding slag on the weld. In addition, during the slag knocking process, multiple clamping plates 1 35, 36 and 37 can be driven to move radially at the same time, and the sponge ring 34 can be pressed against the pipe surface by extrusion. Under the action of the two sponge rings 34, the weld is separated from the rest of the pipe, and the welding slag splashed during the slag knocking process will be intercepted by the sponge ring 34 and It is attached to the sponge ring 34, thereby effectively preventing the welding slag from splashing to the pipe surface area outside the weld during the knocking process, ensuring the appearance quality of the remaining positions of the pipe, and when the welding slag at the pipe weld is knocked off and the pipe is removed, the two sponge rings 34 are driven to reset and move to a suitable spacing, driving the scraper 26 to descend, so that the edge of the scraper 26 and the end surface of the sponge ring 34 close to each other form a scraping, so as to scrape the welding slag remaining on the surface of the sponge ring 34 into the collection box 33, thereby realizing the self-cleaning of the residual welding slag on the surface of the sponge ring 34, avoiding the situation in which the welding slag falls to the weld through the sponge ring 34 during subsequent use, affecting the welding quality. ;
