Metal barrel welding equipment for filter machining

Abstract

The invention discloses metal barrel welding equipment for filter machining, and relates to the technical field of welding equipment. According to the metal barrel welding equipment for filter processing, due to the fact that a barrel is formed by rolling a plate, but the plate has deformation stress, a gap exists in the welding position of the rolled barrel, and therefore the phenomenon of pseudo soldering is likely to occur in the gap position welding process in the welding process; when the welding gun is close to the welding position of the barrel, the ball head is in contact with the two sides of the welding position of the barrel, the contact pressure between the ball head and the barrel is matched with the characteristic that the ends, away from the side sliding blocks, of the connecting rods are close to each other, the two sides of the welding position of the barrel are pressed, it is guaranteed that the welding position of the barrel is tightly attached, and the phenomenon that a plate for rolling the barrel rebounds is avoided. A gap is formed in the welding position of the barrel, insufficient welding occurs in the gap during welding, and the welding effect of the barrel is affected.

Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically to a metal cylinder welding equipment for filter processing. Background Art

[0002] The filter metal cylinder refers to the outer shell part of the filter, usually made of metal materials, used to accommodate and support the filter element to achieve the filtering function. According to the designed dimensions, the metal plate is cut into the required shape and size by a cutting device. Common cutting methods include laser cutting, plasma cutting, and mechanical cutting. For a cylindrical cylinder, the cut metal plate needs to be bent into a cylindrical shape by a bending device, and the bent components and other connecting components are assembled through a welding process to form a complete cylinder structure;

[0003] During the welding process of the cylinder, since the cylinder is formed by rolling the plate, there is deformation stress in the plate, resulting in gaps at the welding positions of the rolled cylinder. Therefore, during the welding process, virtual welding is likely to occur at the gap positions. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A metal cylinder welding equipment for filter processing, comprising:

[0006] A frame body, on one side of the top of the frame body, slide rails are symmetrically arranged, and a first cylinder is fixedly installed on the outer side of the frame body;

[0007] A positioning mechanism, which is fixedly installed inside the frame body, and the positioning mechanism is used to support the cylinder to be welded;

[0008] A cylinder pressing mechanism, which is slidably installed inside the frame body, and the cylinder pressing mechanism is located directly above the positioning mechanism;

[0009] A sliding seat is slidably mounted on the top of the slide rail of the frame body, and a second cylinder is fixedly mounted on the top of the frame body. The output end of the second cylinder is fixedly connected to the outside of the sliding seat. A sliding frame is fixedly mounted on the top of the sliding seat, and a first motor is fixedly mounted on the top of the sliding frame. The output end of the first motor is fixedly mounted with a screw rod. A screw hole block is threadedly connected to the outside of the screw rod. A support block is fixedly mounted at the central position of the side of the screw hole block close to the positioning mechanism. A welding torch is fixedly mounted on the inner wall of the support block. Connecting plates are fixedly mounted on both sides of the top of the screw hole block. The ends of the connecting plates away from the screw hole block are fixedly mounted with sliding groove plates. Plate grooves are formed on the opposite surfaces of the sliding groove plates. Side sliders are slidably mounted at the plate grooves of the sliding groove plates. Connecting rods are fixedly mounted on the outside of the side sliders. By cooperating the connecting rods with the ball heads, when the welding torch approaches the welding position of the cylinder body, the ball heads contact both sides of the welding position of the cylinder body. By using the contact pressure between the ball heads and the cylinder body and the characteristic that the ends of the connecting rods away from the side sliders approach each other, both sides of the welding position of the cylinder body are pressed, ensuring that the welding position of the cylinder body is closely attached, preventing gaps from appearing at the welding position of the cylinder body due to the springback of the plates used to roll the cylinder body, resulting in false welding during welding and affecting the welding effect of the cylinder body. The ends of the connecting rods away from the side sliders are fixedly mounted with ball heads.

[0010] Preferably, elastic rings are clamped at the plate grooves of the sliding groove plates. The ends of the connecting rods away from the side sliders approach each other. Through the elastic deformation of the elastic rings, after the ball heads contact the cylinder body, the contact pressure is transmitted to the elastic rings through the side sliders, causing the elastic rings to deform and buffer. When the welding torch moves along the welding path, the change in the contact pressure between the ball heads and the surface of the cylinder body is buffered, avoiding abnormal protrusions that may cause changes in the contact pressure between the ball heads and the cylinder body. The deformed elastic rings can cause the positions of the ball heads to slide and change, bypassing the abnormal protrusions and ensuring the smooth progress of the welding process. The sides of the elastic rings close to the side sliders are in contact with the outside of the side sliders.

[0011] Preferably, the positioning mechanism includes a turntable and a second motor. The second motor is fixedly mounted at the bottom of the frame body, and the output end of the second motor penetrates through the frame body and extends to its top. The output end of the second motor is fixedly connected to the central position of the bottom of the turntable. The outside of the turntable is rotationally adapted to the inner wall of the frame body, and a bottom cylinder is fixedly mounted on the top of the turntable. A conical cylinder is fixedly mounted on the inner wall of the bottom cylinder.

[0012] Preferably, the outer diameter of the conical cylinder gradually increases from top to bottom, and arc convex strips are fixedly installed on the outer side of the conical cylinder. By the cooperation of the conical cylinder and the arc convex strips, and using the characteristic that the outer diameter of the conical cylinder gradually increases from top to bottom, when the supporting cylinder plate supports the cylinder body, during the downward pressing process of the pressing cylinder mechanism, the cylinder body moves downward, and the edge position at the bottom of the inner wall of the cylinder body gradually contacts the arc convex strips, restricting the downward movement of the cylinder body, making the center position of the cylinder body correspond to the center position of the conical cylinder, realizing the positioning of the cylinder body, avoiding the deviation of the cylinder body, and preventing the distance between the welding torch and the welding position of the cylinder body from being too large to achieve welding. The arc convex strips are evenly installed along the center position of the conical cylinder. Strip grooves are evenly opened on the outer side of the conical cylinder. A fixed disk is fixedly installed on the inner wall of the bottom cylinder. The fixed disk is located below the conical cylinder. A fixed rod is fixedly installed at the center position of the top of the fixed disk. A supporting cylinder plate is slidably installed on the outer side of the fixed rod. The outer side of the supporting cylinder plate is slidably adapted to the strip grooves of the conical cylinder. And a spring is fixedly installed between the supporting cylinder plate and the fixed disk.

[0013] Preferably, a top disk is fixedly installed at the top end of the fixed rod. Wheel groove blocks are fixedly installed on the outer side of the top disk. Wheel grooves are opened on both sides of the wheel groove blocks. And the wheel groove blocks are evenly installed along the center position of the top disk. Rotating wheels are slidably installed at the wheel grooves of the wheel groove blocks. By the cooperation of the rotating wheels and the elastic rings, using the contact between the inner wall of the cylinder body and the rotating wheels, and through the contact pressure, the elastic rings deform to generate elastic force, providing a certain supporting force on the inner wall of the cylinder body, avoiding the inclination of the cylinder body during the positioning movement, resulting in the cylinder body being squeezed and deformed under pressure. And elastic rings are clamped at the wheel grooves of the wheel groove blocks. One end of the elastic ring close to the rotating wheel contacts the outer side of the rotating wheel.

[0014] Preferably, the pressing cylinder mechanism includes a sliding plate. The sliding plate is slidably adapted to the inner wall of the frame body. And the bottom of the sliding plate is fixedly connected to the output end of the first cylinder. A top plate is fixedly installed on the outer side of the sliding plate. The top plate is located directly above the positioning mechanism. A top pressing cylinder is fixedly installed at the bottom of the top plate. The outer diameter of the top pressing cylinder gradually decreases from top to bottom. A top pad is fixedly installed at the bottom of the top plate. The top pad is located outside the top pressing cylinder. And notches are opened on the side of the top pad and the top pressing cylinder close to the welding torch. A side support plate is fixedly installed at the bottom of the top plate. By the cooperation of the side support plate and the top pressing cylinder, during the process of pressing down the cylinder body, the position of the cylinder body is adjusted, and positioning processing is carried out in cooperation with the positioning mechanism. At the same time, the notch of the top pressing cylinder cooperates with the welding torch to avoid contacting the welding position of the cylinder body, preventing the cylinder body and the equipment from being welded and adhered under the high temperature of welding. The side support plate is located between the top pad and the top pressing cylinder. And the side support plate is an arc-shaped plate with the bottom end inclined away from the top pressing cylinder. The side support plate is located on the side away from the notch. And side pressing strips are evenly installed on the arc surface of the side support plate close to the top pressing cylinder.

[0015] The present invention provides a welding device for a metal cylinder body in filter processing. It has the following beneficial effects:

[0016] First, in this welding device for the metal cylinder body in filter processing, through the cooperation of the connecting rod and the ball head, when the welding torch approaches the welding position of the cylinder body, the ball head contacts both sides of the welding position of the cylinder body. Utilizing the contact pressure between the ball head and the cylinder body and the characteristic that the ends of the connecting rod away from the side slider approach each other, both sides of the welding position of the cylinder body are pressed, ensuring that the welding position of the cylinder body fits tightly, preventing gaps from appearing at the welding position of the cylinder body due to the springback of the plate material used to roll the cylinder body, which may cause false welding during welding and affect the welding effect of the cylinder body.

[0017] Second, in this welding device for the metal cylinder body in filter processing, through the elastic deformation of the elastic ring, after the ball head contacts the cylinder body, the contact pressure is transmitted to the elastic ring through the side slider, causing the elastic ring to deform and buffer. When the welding torch moves along the welding path, it buffers the change in the contact pressure between the ball head and the surface of the cylinder body, avoiding abnormal protrusions that may cause changes in the contact pressure between the ball head and the cylinder body. The deformed elastic ring allows the position of the ball head to slide and change, bypassing the abnormal protrusions to ensure the smooth progress of the welding process.

[0018] Third, in this welding device for the metal cylinder body in filter processing, through the cooperation of the conical cylinder and the arc convex strip, using the characteristic that the outer diameter of the conical cylinder gradually increases from top to bottom, when the supporting cylinder plate supports the cylinder body and the pressing cylinder mechanism presses down, the cylinder body moves downward, and the edge position at the bottom of the inner wall of the cylinder body gradually contacts the arc convex strip, restricting the downward movement of the cylinder body, making the center position of the cylinder body correspond to the center position of the conical cylinder, realizing the positioning of the cylinder body, avoiding the cylinder body from shifting, and preventing the distance between the welding torch and the welding position of the cylinder body from being too large to achieve welding.

[0019] Fourth, in this welding device for the metal cylinder body in filter processing, through the cooperation of the rotating wheel and the elastic ring, utilizing the contact between the inner wall of the cylinder body and the rotating wheel, and causing the elastic ring to deform and generate elastic force through the contact pressure, a certain supporting force is provided on the inner wall of the cylinder body, avoiding the cylinder body from tilting during positioning and movement, which may cause the cylinder body to be deformed under pressure.

[0020] Fifth, in this welding device for the metal cylinder body in filter processing, through the cooperation of the side support plate and the top pressing cylinder, during the process of pressing down the cylinder body, the position of the cylinder body is adjusted, and it is cooperated with the positioning mechanism for positioning. At the same time, the notch of the top pressing cylinder cooperates with the welding torch to avoid contacting the welding position of the cylinder body, preventing the cylinder body and the equipment from being welded and adhered under the high temperature of welding.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The first embodiment, asFigures 1 to 5 As shown in the figure, the present invention provides a technical solution:

[0034] A metal cylinder welding device for filter processing, comprising:

[0035] A frame body 1, on one side of the top of the frame body 1, slide rails are symmetrically arranged, and a first cylinder 4 is fixedly installed on the outer side of the frame body 1;

[0036] A positioning mechanism 2, which is fixedly installed inside the frame body 1, and the positioning mechanism 2 is used to support the cylinder to be welded;

[0037] A cylinder pressing mechanism 3, which is slidably installed inside the frame body 1, and the cylinder pressing mechanism 3 is located directly above the positioning mechanism 2;

[0038] A sliding seat 8 is slidably installed on the top of the slide rail of the frame body 1, and a second cylinder 7 is fixedly installed on the top of the frame body 1. The output end of the second cylinder 7 is fixedly connected to the outer side of the sliding seat 8. A sliding frame 6 is fixedly installed on the top of the sliding seat 8, a first motor 5 is fixedly installed on the top of the sliding frame 6, and an output end of the first motor 5 is fixedly installed with a screw rod 9. When the second cylinder 7 drives the sliding seat 8 and the sliding frame 6 to approach the positioning mechanism 2, the welding torch 14 gradually approaches the welding position of the metal cylinder. At the same time, the screw hole block 10 inside the sliding frame 6 drives the sliding groove plate 15 through the connecting plate 12, so that the side slider 16 at the groove of the sliding groove plate 15 drives the ball head 18 to contact the positioned and fixed cylinder through the connecting rod 17. The outer side of the screw rod 9 is threadedly connected with the screw hole block 10. A support block 11 is fixedly installed at the central position on the side of the screw hole block 10 close to the positioning mechanism 2. A welding torch 14 is fixedly installed on the inner wall of the support block 11. Connecting plates 12 are fixedly installed on both sides of the top of the screw hole block 10. The connecting plates 12 are fixedly installed with sliding groove plates 15 at the ends far from the screw hole block 10. Plate grooves are opened on the opposite surfaces of the sliding groove plates 15, and side sliders 16 are slidably installed at the plate grooves of the sliding groove plates 15. Due to the characteristic that the ends of the connecting rods 17 far from the side sliders 16 approach each other, after contacting the cylinder, after the ball head 18 contacts the cylinder, then under the drive of the second cylinder 7, the contact pressure gradually increases, so that the ball head 18 squeezes the cylinder on both sides of the welding position of the cylinder, making the welding position of the cylinder fit tightly. At the same time, when contacting, the contact pressure is transmitted to the elastic ring 13 through the side slider 16, causing the elastic ring 13 to elastically deform and buffer the contact pressure. The outer side of the side slider 16 is fixedly installed with a connecting rod 17, and the end of the connecting rod 17 far from the side slider 16 is fixedly installed with a ball head 18.

[0039] Elastic rings 13 are clamped at the plate grooves of the sliding groove plates 15. The ends of the connecting rods 17 far from the side sliders 16 approach each other, and the side of the elastic ring 13 close to the side slider 16 is in contact with the outer side of the side slider 16.

[0040] Second embodiment, on the basis of the first embodiment, please refer toFigures 6 to 8 As shown, the positioning mechanism 2 includes a turntable 201 and a second motor 202. The second motor 202 is fixedly installed at the bottom of the frame body 1, and the output end of the second motor 202 penetrates through the frame body 1 and extends to its top. The output end of the second motor 202 is fixedly connected to the central position at the bottom of the turntable 201. The outer side of the turntable 201 is rotationally adapted to the inner wall of the frame body 1, and a bottom cylinder 203 is fixedly installed on the top of the turntable 201. A conical cylinder 208 is fixedly installed on the inner wall of the bottom cylinder 203.

[0041] The outer diameter of the conical cylinder 208 gradually increases from top to bottom, and arc convex strips 207 are fixedly installed on the outer side of the conical cylinder 208. The arc convex strips 207 are evenly installed along the center position of the conical cylinder 208. Strip grooves are evenly opened on the outer side of the conical cylinder 208. Workers place the cylinder to be welded into the top of the conical cylinder 208, so that the top plate 205 is inside the cylinder. At the same time, the bottom of the metal cylinder is contacted through the supporting cylinder plate 204 to provide support for the metal cylinder. With the downward movement of the pressing cylinder mechanism 3, a fixed plate 209 is fixedly installed on the inner wall of the bottom cylinder 203. The fixed plate 209 is located below the conical cylinder 208. A fixed rod 206 is fixedly installed at the central position of the top of the fixed plate 209. A supporting cylinder plate 204 is slidably installed on the outer side of the fixed rod 206. The outer side of the supporting cylinder plate 204 is slidably adapted to the strip grooves of the conical cylinder 208, and a spring 210 is fixedly installed between the supporting cylinder plate 204 and the fixed plate 209.

[0042] The top end of the fixed rod 206 is fixedly installed with a top plate 205. Wheel groove blocks 212 are fixedly installed on the outer side of the top plate 205. Wheel grooves are opened on both sides of the wheel groove blocks 212, and the wheel groove blocks 212 are evenly installed along the center position of the top plate 205. The pressing cylinder mechanism 3 is used to contact the top of the cylinder and gradually apply pressure to the cylinder, so that the cylinder transfers the pressure to the spring 210 through the supporting cylinder plate 204, causing the spring 210 to deform and compress. At the same time, the supporting cylinder plate 204 moves downward, so that the arc convex strips 207 evenly installed on the outer side of the conical cylinder 208 contact the edge position at the bottom of the inner wall of the cylinder, and cooperate with the pressing cylinder mechanism 3 to position the cylinder. Subsequently, the turntable 201 is driven to rotate by the second motor 202, so that the welding position of the cylinder corresponds to the position of the welding torch 14. Rotating wheels 211 are slidably installed at the wheel grooves of the wheel groove blocks 212, and elastic rings 213 are clamped at the wheel grooves of the wheel groove blocks 212. One end of the elastic ring 213 close to the rotating wheel 211 contacts the outer side of the rotating wheel 211.

[0043] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 9 to 10As shown, the pressing cylinder mechanism 3 includes a sliding plate 33. The sliding plate 33 is slidably adapted to the inner wall of the frame body 1, and the bottom of the sliding plate 33 is fixedly connected to the output end of the first cylinder 4. A top plate 31 is fixedly installed on the outer side of the sliding plate 33. The top plate 31 is located directly above the positioning mechanism 2. By connecting the sliding plate 33 to the output end of the first cylinder 4, the first cylinder 4 drives the sliding plate 33 to move downward, causing the top plate 31 to move downward. While moving downward, the top pressing cylinder 32 and the side support plate 35 are driven to move synchronously. A top pressing cylinder 32 is fixedly installed at the bottom of the top plate 31. The outer diameter of the top pressing cylinder 32 gradually decreases from top to bottom. A top pad 34 is fixedly installed at the bottom of the top plate 31. The top pad 34 is located outside the top pressing cylinder 32, and notches are provided on both the top pad 34 and the side of the top pressing cylinder 32 close to the welding torch 14. A side support plate 35 is fixedly installed at the bottom of the top plate 31. The side support plate 35 is located between the top pad 34 and the top pressing cylinder 32, and the side support plate 35 is an arc-shaped plate with the bottom end inclined away from the top pressing cylinder 32. During the movement process, through the cooperation of the side support plate 35 and the top pressing cylinder 32, by utilizing the arc-shaped inclination of the side support plate 35 and the change in the outer diameter of the top pressing cylinder 32, during the downward movement, the side support plate 35 contacts the cylinder body with a larger offset amount to pre-adjust the position of the cylinder body, ensuring that the top pressing cylinder 32 smoothly enters the interior of the cylinder body. And during the gradual downward movement, in cooperation with the conical cylinder 208, it gradually contacts the edge position at the top of the inner wall of the cylinder body to position the cylinder body. The side support plate 35 is located on the side away from the notch, and side pressure strips 36 are evenly installed on the arc surface of the side support plate 35 close to the top pressing cylinder 32.

[0044] During use, the rolled and formed metal cylinder body is placed on the top of the positioning mechanism 2. Subsequently, the first cylinder 4 is started, so that the first cylinder 4 drives the pressing cylinder mechanism 3 to move downward. In cooperation with the support of the positioning mechanism 2 for the metal cylinder body, while fixing the cylinder body, the position of the cylinder body is positioned, and the positioning mechanism 2 drives the cylinder body to rotate so that the welding position of the cylinder body corresponds to the welding torch 14. Subsequently, the second cylinder 7 drives the sliding seat 8 and the sliding frame 6, so that the welding torch 14 approaches the welding position of the cylinder body. Finally, the second motor 202 drives the screw rod 9 to rotate, driving the screw hole block 10 to move along the welding path of the cylinder body to realize the welding of the metal cylinder body.

[0045] When the second cylinder 7 drives the slide block 8 and the slide frame 6 to approach the positioning mechanism 2, the welding torch 14 gradually approaches the welding position of the metal cylinder. At the same time, the screw hole block 10 inside the slide frame 6 drives the chute plate 15 through the connecting plate 12, so that the side slider 16 at the plate groove of the chute plate 15 drives the ball head 18 to contact the cylinder after being positioned and fixed through the connecting rod 17. And due to the characteristics that the ends of the connecting rod 17 away from the side slider 16 approach each other, after contacting the cylinder, after the ball head 18 contacts the cylinder, then under the drive of the second cylinder 7, the contact pressure gradually increases, so that the ball head 18 presses the cylinder on both sides of the welding position of the cylinder, making the welding position of the cylinder fit tightly. At the same time, when contacting, the contact pressure is transmitted to the elastic ring 13 through the side slider 16, causing the elastic ring 13 to deform elastically and buffer the contact pressure.

[0046] In the positioning mechanism 2, the worker puts the cylinder to be welded into the top of the conical cylinder 208, so that the top plate 205 is inside the cylinder. At the same time, the cylinder is supported by contacting the bottom of the metal cylinder through the supporting cylinder plate 204. Cooperating with the downward movement of the cylinder pressing mechanism 3, the cylinder pressing mechanism 3 contacts the top of the cylinder and gradually presses the cylinder, so that the cylinder transmits the pressure to the spring 21 by the supporting cylinder plate 204, causing the spring 210 to deform and compress. At the same time, the supporting cylinder plate 204 moves downward, so that the arc-shaped convex strips 207 uniformly installed on the outside of the conical cylinder 208 contact the edge position at the bottom of the inner wall of the cylinder, and cooperate with the cylinder pressing mechanism 3 to position the cylinder. Subsequently, the second motor 202 drives the turntable 201 to rotate, so that the welding position of the cylinder corresponds to the position of the welding torch 14.

[0047] In the cylinder pressing mechanism 3, the slide plate 33 is connected to the output end of the first cylinder 4. The first cylinder 4 drives the slide plate 33 to move downward, so that the top plate 31 moves downward, and at the same time drives the top pressing cylinder 32 and the side support plate 35 to move synchronously during the downward movement. During the movement, through the cooperation of the side support plate 35 and the top pressing cylinder 32, using the arc-shaped inclination of the side support plate 35 and the outer diameter change of the top pressing cylinder 32, during the downward movement, the side support plate 35 contacts the cylinder with a large offset to pre-adjust the position of the cylinder, ensuring that the top pressing cylinder 32 smoothly enters the inside of the cylinder, and during the gradual downward movement, cooperating with the conical cylinder 208, gradually contacts the edge position at the top of the inner wall of the cylinder to position the cylinder.
