Description

Technical Field

[0001] The invention relates to the technical field of welding of filter system components, in particular to a welding device for filter system components. Background Art

[0002] A filtration system is a system used to separate, screen or purify substances. This type of system is usually used in water treatment, air filtration and industrial filtration. In water treatment filtration systems, multi-media filters are usually used for filtration. In the production and processing of multi-media filters, it is necessary to Fig.10 The orifice plate for filtering shown is welded to a straight cylinder used as an external frame, and a positioning hole is provided at the center of the orifice plate.

[0003] When actually welding the orifice plate and the straight tube, the bottom positioning device is usually used to position the straight tube first. After the straight tube is positioned, the orifice plate is inserted into the straight tube to complete the combination of the two. Then, the orifice plate is fixed in position with an arc-shaped positioning device placed on the inner wall of the straight tube. Finally, the operator welds the part where the orifice plate contacts the inner wall of the straight tube.

[0004] Although the above welding method can effectively perform positioning welding on the straight cylinder and the orifice plate, the orifice plate itself is a thin plate and is easily deformed during the installation or welding process, which makes it easy for the orifice plate and the straight cylinder to not contact properly, resulting in reduced welding accuracy. The actual coping method is to first perform multi-point welding on the contact position between the orifice plate and the inner wall of the straight cylinder, and finally perform full annular welding to improve the welding accuracy during the orifice plate welding process. However, the above coping method can only improve the welding accuracy and cannot directly solve the problem of easy deformation of the orifice plate; in addition, the side wall of the straight cylinder will also deform due to welding stress, resulting in a large gap between the orifice plate and the straight cylinder, resulting in missing welds and leaks. In the actual welding process, the position of the orifice plate and the straight cylinder needs to be adjusted before welding, but the above method comes at the expense of reducing the welding speed, thereby greatly reducing the welding efficiency and cannot solve the problem of deformation of the straight cylinder from the root.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0031] See also Figure 1-Figure 2 A filtering system component welding device comprises a horizontal bottom plate 1, a fixing plate 11 and a vertical plate 12 are respectively fixed at the left and right ends of the top of the horizontal bottom plate 1, a hole plate positioning part 2 is installed on the right side of the fixing plate 11 through an electric push rod 111, a straight cylinder mounting part 3 is arranged on the left side of the vertical plate 12, a welding machine 4 and a corrective part 5 are fixed on the top of the horizontal bottom plate 1 from left to right in sequence, and the welding machine 4 and the corrective part 5 are located between the hole plate positioning part 2 and the straight cylinder mounting part 3.

[0032] The present invention installs and positions the straight cylinder and the orifice plate to be welded respectively through the straight cylinder installation part 3 and the orifice plate positioning part 2, so that the orifice plate after installation and positioning is consistent with the center line position of the straight cylinder, thereby facilitating the combination of the two. Before the orifice plate and the straight cylinder are combined, the straight cylinder is pre-corrected in the welding position through the correction part 5, so as to ensure that the orifice plate and the straight cylinder can be accurately combined, and the correction part 5 can also prevent the straight cylinder from being locally deformed due to welding stress.

[0033] Specifically, the orifice plate is first lifted to the position of the orifice plate positioning part 2 by an external device, and then the orifice plate positioning part 2 is used to cooperate with the positioning hole in the center of the orifice plate for positioning and installation, and then the straight cylinder is lifted to between the straight cylinder mounting part 3 and the orifice plate positioning part 2 by an external device, and then the straight cylinder is installed and positioned by the straight cylinder mounting part 3. After the straight cylinder is positioned, the straight cylinder is driven to rotate by the straight cylinder mounting part 3, so as to cooperate with the correcting part 5 to pre-correct the welding position of the straight cylinder.

[0034] After the correction is completed, the straight cylinder mounting part 3 is controlled to stop driving the straight cylinder to rotate, and then the electric push rod 111 is controlled to push the orifice plate positioning part 2 and the orifice plate to the right, so that the orifice plate is inserted into the straight cylinder, and then the contact position of the orifice plate and the straight cylinder is welded by the welding machine 4, so that the orifice plate and the straight cylinder are preliminarily connected. After the preliminary connection is completed, the straight cylinder mounting part 3 is controlled to drive the straight cylinder to rotate. At this time, the orifice plate will rotate synchronously with the straight cylinder due to the preliminary connection with the straight cylinder. At this time, the contact position of the orifice plate and the straight cylinder is continuously welded by the welding machine 4 until all the contact positions of the straight cylinder and the orifice plate are welded.

[0035] It should be noted that the welding machine 4 is specifically an automatic welding arm, which can automatically align the contact position between the straight cylinder and the orifice plate, and can automatically avoid the orifice plate during the combination of the orifice plate and the straight cylinder. The automatic welding arm is more common in the actual welding process, so it will not be described in detail.

[0036] See also Figure 1-Figure 3 The orifice plate positioning part 2 includes a moving plate 21 fixed to the pushing end of the electric push rod 111, a connecting column 211 is rotatably installed on the right side of the moving plate 21, a median column 212 is fixed to the right end of the connecting column 211, a center positioning component 22 is provided on the median column 212, and a rolling component 23 is connected to the connecting column 211 and the center positioning component 22. The orifice plate positioning part 2 is used to match the positioning hole in the center of the orifice plate to position the orifice plate, so that the center of the orifice plate and the straight tube are positioned after positioning. In addition, the shape of the orifice plate is stabilized by the rolling component 23 in cooperation with the center positioning component 22, so as to ensure the stability of the orifice plate during welding, and further ensure the welding accuracy of the orifice plate and the straight tube. The rolling component 23 continuously rolls, which can eliminate the deformation of the orifice plate caused by welding stress during welding, and thus avoid the deformation of the orifice plate during welding, which leads to poor welding accuracy.

[0037] Specifically, the orifice plate is first hoisted to the position of the orifice plate positioning part 2 by an external device. After it is hoisted to the position where the positioning hole in the center of the orifice plate is aligned with the center column 212, the external device is controlled to hoist the orifice plate toward the center column 212. During the hoisting process, manual auxiliary installation is required so that the center positioning component 22 completes the positioning of the orifice plate. After the orifice plate is positioned, the rolling component 23 presses against the left side of the orifice plate.

[0038] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The center positioning component 22 includes a plurality of inner grooves uniformly arranged on the side of the median column 212 in the circumferential direction, each inner groove is connected with a pressure block 221 through an inner spring, a pressure slope is arranged on the right side of the pressure block 221, and a pressing structure for cooperating with the pressure block 221 to install and position the orifice plate is arranged at the left end of the side of the median column 212; an avoidance groove 313 for avoiding the median column 212 is arranged at the left end of the straight cylinder mounting portion 3; the pressing structure includes a mounting plate 222 uniformly fixed on the side of the median column 212 in the circumferential direction, and an elastic telescopic rod 223 is fixed to the right side surface of one end of each mounting plate 222 away from the median column 212, and a right abutment plate 224 is installed on the telescopic end of the elastic telescopic rod 223; a pressing component 33 for cooperating with the center positioning component 22 and the rolling component 23 to roll the orifice plate and prevent its deformation is arranged at the left end of the rotating column 311.

[0039] The center positioning component 22 is used to accurately position the orifice plate during the installation process of the orifice plate, and through the pressure block 221 and the avoidance groove 313, the orifice plate positioning part 2 can be separated from the orifice plate after the orifice plate and the straight cylinder are welded, so as to facilitate the removal of the welded orifice plate and the straight cylinder, thereby improving the welding efficiency of the orifice plate and the straight cylinder. At the same time, the pressure structure can balance the force that pushes the orifice plate to the left when the inner wall of the straight cylinder contacts the orifice plate during the combination of the orifice plate and the straight cylinder, thereby avoiding deformation of the orifice plate before welding and affecting the welding accuracy.

[0040] Specifically, in the process of controlling the external device to lift the orifice plate toward the median column 212, the median column 212 passes through the positioning hole at the center of the orifice plate, and the orifice plate will press against the right abutment plate 224. Then the operator assists in pushing the orifice plate to the left, so that the orifice plate pushes the right abutment plate 224 to the left and compresses the elastic telescopic rod 223. In the process of the orifice plate moving to the left, the positioning hole in the center of the orifice plate will push the pressure block 221 into the inner groove through the pressure slope and compress the inner spring. When the orifice plate moves to the left to the left side of the pressure block 221, the pressure block 221 will pop out due to the elastic force of the inner spring and limit the right side of the orifice plate. At the same time, the right abutment plate 224 has a tendency to push the orifice plate to the right, and the pressure block 221 can prevent the orifice plate from moving to the right, thereby accurately positioning the orifice plate.

[0041] Continue reading Figure 2-Figure 4The rolling component 23 includes a middle rod 231 hinged on the end of the mounting plate 222 away from the middle column 212, and the left end of the middle rod 231 is commonly connected with an intermittent rightward movement structure, and the right end of each middle rod 231 is fixed with an elastic telescopic square rod, and the telescopic end of the elastic telescopic square rod is fixed with a mounting frame 232, and a pressing roller 233 is installed on the mounting frame 232; the intermittent rightward movement structure includes a horizontal slide groove 234 opened in the middle of the connecting column 211, and a limit rod 235 is slidably connected in the horizontal slide groove 234, and the limit rod 2 A return spring is connected between 35 and the right side of the horizontal slide groove 234, and a moving ring 236 is commonly connected between the upper and lower ends of the limit rod 235. A connecting telescopic rod is hinged on the outer ring surface of the moving ring 236 and corresponds to each middle rod 231. The telescopic end of the connecting telescopic rod is connected to the left end of the middle rod 231, and an arc-shaped push block 237 is fixed on the left side of the moving ring 236; a plurality of right push protrusions 238 for pushing the arc-shaped push block 237 are evenly fixed on the right side of the moving plate 21 with the connecting column 211 as the center.

[0042] The rolling component 23 is used to push the orifice plate to the right as a whole, thereby ensuring that the orifice plate is firmly positioned, and can continue to roll the orifice plate during the welding process of the orifice plate and the straight cylinder, thereby eliminating the tendency of the orifice plate to deform due to welding stress, and can also level the orifice plate, so that the orifice plate remains in a vertical state and is always in a position to fit the inner wall of the straight cylinder. At the same time, the intermittent rightward movement structure can drive multiple pressing rollers 233 to roll the orifice plate synchronously multiple times during the welding process of the orifice plate and the straight cylinder, thereby increasing the rolling effect on the orifice plate, and further ensuring that the orifice plate is in a flat state during the welding process.

[0043] Specifically, during the process of the center positioning component 22 positioning the orifice plate, the orifice plate pushes the pressing roller 233 and the mounting frame 232 to the left and compresses the elastic telescopic square rod, so that the pressing roller 233 is continuously pressed against the left side of the orifice plate.

[0044] In the subsequent process of controlling the straight cylinder mounting part 3 to drive the straight cylinder to rotate and weld the orifice plate and the straight cylinder, the orifice plate rotates together with the straight cylinder mounting part 3 through the initial connection with the straight cylinder, and due to the pressing action of the pressing component 33, the center positioning component 22 and the rolling component 23, the connecting column 211 and the middle column 212 rotate together with the orifice plate. During the rotation of the connecting column 211 and the middle column 212, the right push protrusion 238 will contact the arc-shaped push block 237 and push the arc-shaped push block 237 to the right, thereby causing the movable ring 236 to move to the right. As the movable ring 236 moves to the right, the middle rod 231 will rotate through the position change of the connecting telescopic rod, and cause the elastic telescopic square rod, the mounting frame 232 and the pressing roller 233 to rotate together, thereby causing the pressing roller 233 to continuously roll along the left side of the orifice plate, and through the continuous pressing of the pressing component 33 on the right side of the orifice plate, the tendency of the orifice plate to be deformed due to welding stress is eliminated.

[0045] See also Figure 1 , Figure 5-Figure 7 The straight-tube mounting portion 3 includes a motor 31 mounted on the left side of the vertical plate 12 through a motor box, a rotating column 311 is fixed to the output end of the motor 31, a stabilizing plate 312 is fixed to the side of the rotating column 311, two inner positioning components 32 are arranged in the rotating column 311 and on the left side of the stabilizing plate 312, and a power structure for providing power to the inner positioning components 32 is also arranged in the rotating column 311; a coordination block 13 is fixed to the top of the horizontal bottom plate 1 and corresponds to the stabilizing plate 312, and the coordination block 13 is slidably connected to the stabilizing plate 312.

[0046] The straight cylinder installation part 3 is used to install and position the straight cylinder, so that the center of the installed straight cylinder coincides with the center of the installed orifice plate, thereby facilitating the combination of the two. Specifically, after the orifice plate positioning part 2 completes the positioning of the orifice plate, the straight cylinder is first hoisted between the straight cylinder installation part 3 and the orifice plate positioning part 2 by an external device, and then the straight cylinder is hoisted to the right by an external device, so that the straight cylinder passes through the two internal positioning components 32 and is finally pressed against the left side of the stabilizing plate 312, and then the power structure is controlled to drive the internal positioning component 32 to internally support the straight cylinder, thereby completing the center positioning of the straight cylinder.

[0047] See also Figure 6-Figure 8The rotating column 311 has a hollow groove 321, and the inner positioning component 32 includes a plurality of sliding grooves connected to the hollow groove 321 and uniformly arranged on the side of the rotating column 311. A sliding rod 322 is slidably connected in each sliding groove. An arc-shaped abutment plate 323 is fixed to the end of the sliding rod 322 away from the hollow groove 321. A push slope driven by the power structure is provided at the end of the sliding rod 322 located in the hollow groove 321. A spring plate 323 is fixed to the right side of each sliding rod 322. 24. A tension spring is connected between the spring plate 324 and the rotating column 311. The power structure includes a cylinder 325 fixed on the right side of the stabilizing plate 312. An L-shaped push rod 326 is fixed to the pushing end of the cylinder 325. A push block 327 is fixed to the horizontal end of the L-shaped push rod 326 and at the position of each inner positioning component 32. The right end of the push block 327 is a conical structure. The push block 327 can push all the slide bars 322 outward through the push slope.

[0048] The inner positioning component 32 is used to position and support the inner wall of the straight cylinder by means of multiple arc-shaped support plates 323, thereby ensuring that the center of the straight cylinder is consistent with the center position of the orifice plate after positioning is completed, and through the two-point support positioning method, the straight cylinder as a whole is protected by multi-point pressure on the inner wall of the straight cylinder, thereby cooperating with the corrective part 5 to prevent the straight cylinder from being deformed during welding.

[0049] Specifically, when the straight tube is lifted by an external device and passes through the two internal positioning components 32 and is finally pressed against the left side of the stabilizing plate 312, the control cylinder 325 pushes the L-shaped push rod 326 to the right, and the L-shaped push rod 326 drives the two push blocks 327 to move to the right, so that the push blocks 327 push the slide bar 322 to move outward through the push slope, and drive the arc-shaped push plate 323 to support the inner wall of the straight tube through the slide bar 322, and then the straight tube is internally supported and positioned through the two internal positioning components 32.

[0050] See also Figure 1 , Figure 5 and Fig. 9The orthopedic part 5 includes a limiting slide rail 51 which is symmetrically fixed on the top of the horizontal base plate 1 front and back, and the left end of each limiting slide rail 51 is connected to a horizontal slider 511 through a connecting spring, and a collecting plate 512 is fixed to the top of each horizontal slider 511, and a left-moving component 52 is commonly connected between the two collecting plates 512, and a rotating plate 513 is hinged on the top of each collecting plate 512, and an arc-shaped orthopedic plate 514 is fixed to the end of each rotating plate 513 away from the collecting plate 512, and L-shaped upper extension plates 515 are fixed to the opposite sides of the two collecting plates 512, and a longitudinal spring is connected between the vertical end of the L-shaped upper extension plate 515 and the rotating plate 513, and lifting rods 516 are fixed to the opposite sides of the two rotating plates 513; a lifting protrusion 517 for lifting the lifting rod 516 is fixed at the position of each lifting rod 516 on the top of the horizontal base plate 1.

[0051] See also Figure 5 , Figure 6 and Fig. 9 The left-moving component 52 includes a synchronization rod 521 fixed between the two collecting plates 512, and a right extension rod 522 is fixed at the middle position of the right end of the synchronization rod 521; a plurality of left-pushing protrusions 523 for pushing the right extension rod 522 to the left are evenly arranged on the left side of the stabilizing plate 312.

[0052] The corrective part 5 is used to perform targeted correction on the straight tube welding position. The arc-shaped corrective plate 514 continuously resists the side wall of the straight tube, and the left-moving component 52 drives the arc-shaped corrective plate 514 to move back and forth left and right, thereby increasing the corrective effect of the arc-shaped corrective plate 514 on the side wall of the straight tube. At the same time, the lifting protrusion 517 pushes the lifting rod 516 upward, so that the arc-shaped corrective plate 514 swings back and forth, thereby further increasing the corrective effect of the arc-shaped corrective plate 514 on the side wall of the straight tube.

[0053] Specifically, after the two inner positioning components 32 complete the inner support positioning of the straight cylinder, the arc-shaped corrective plate 514 is pressed against the side wall of the straight cylinder, and the motor 31 is first controlled to drive the rotating column 311 and the two inner positioning components 32 to rotate, so that the two inner positioning components 32 drive the straight cylinder to rotate. As the straight cylinder rotates, the arc-shaped corrective plate 514 corrects the side wall of the straight cylinder, and the rotating column 311 will drive the stabilizing plate 312 to continue to rotate with it, so that the multiple left-pushing protrusions 523 push the right extension rod 522 to the left in turn, and drive the two collecting plates 512 to move to the left synchronously, and the arc-shaped corrective plate 514 will move to the left and correct the straight cylinder along the side wall of the straight cylinder.

[0054] When the arc-shaped corrective plate 514 moves to the left, the lifted rod 516 will move to the left together with the rotating plate 513 and the arc-shaped corrective plate 514. When the lifted rod 516 contacts the lifting protrusion 517, the lifted rod 516 is pushed upward by the lifting protrusion 517 to drive the rotating plate 513 to rotate, thereby causing the arc-shaped corrective plate 514 to swing back and forth, thereby increasing the corrective effect on the side of the straight tube.

[0055] In this embodiment, if Fig. 9 As shown, a telescopic adjustment structure is provided in the middle of the rotating plate 513, so that the arc-shaped correction plate 514 can correct straight tubes of different sizes.

[0056] See also Figure 7 and Figure 8 The pressing component 33 includes a rotating rod 331 that is evenly hinged on the left end of the side of the rotating column 311. The number of the rotating rods 331 is consistent with the number of the right pressing plate 224. Each rotating rod 331 is hinged with a pressing plate 332 at one end away from the rotating column 311. An extension plate 333 is fixed to the side of the rotating column 311 and corresponds to the position of the rotating rod 331. A compression spring is connected between the extension plate 333 and the rotating rod 331.

[0057] The pressing component 33 is used to cooperate with the rolling component 23 and the right pressing plate 224 to position the orifice plate, and can prevent the rolling component 23 from excessively rolling and deforming the orifice plate. Specifically, when the correction part 5 completes the correction of the side wall of the straight cylinder, the electric push rod 111 is controlled to push the orifice plate positioning part 2 and the orifice plate to the right, so that the orifice plate is inserted into the straight cylinder. During the process of inserting the orifice plate into the straight cylinder, the pressure block 221 will return to the inner groove due to the pressure of the avoidance groove 313, and the pressing plate 332 will replace the pressure block 221 to limit the right side of the orifice plate, so that the orifice plate is always in a vertical state, and the rolling pressure of the rolling component 23 is balanced by the pressing plate 332.

[0058] After the orifice plate and the straight cylinder are combined, the welding machine 4 that previously avoided the combination of the orifice plate and the straight cylinder is controlled to perform preliminary welding on the contact position of the orifice plate and the straight cylinder, and then the motor 31 is controlled again to drive the rotating column 311 and the two internal positioning components 32 to rotate, so that the two internal positioning components 32 drive the straight cylinder to rotate, and the welding machine 4 continues to weld the connecting part of the orifice plate and the straight cylinder until the connecting part of the orifice plate and the straight cylinder is completely welded, and then the positioning effect of the orifice plate positioning part 2 on the orifice plate is removed, and then the internal positioning component 32 is controlled to release the internal support of the straight cylinder, and finally the welded orifice plate and the straight cylinder are removed together through an external device.

[0059] See also Figure 1-Figure 10The working steps of the present invention are as follows: the first step is to lift the orifice plate to the position of the orifice plate positioning part 2 by an external device. After the positioning hole in the center of the orifice plate is aligned with the median column 212, the external device is controlled to lift the orifice plate toward the median column 212. During the lifting process, manual auxiliary installation is required so that the center positioning component 22 completes the positioning of the orifice plate. After the orifice plate is positioned, the rolling component 23 presses against the left side of the orifice plate.

[0060] In the second step, after the orifice plate positioning part 2 completes the positioning of the orifice plate, the straight cylinder is first hoisted to between the straight cylinder mounting part 3 and the orifice plate positioning part 2 by an external device, and then the straight cylinder is hoisted to the right by an external device, so that the straight cylinder passes through the two inner positioning parts 32 and finally presses against the left side of the stabilizing plate 312, and then the power structure is controlled to drive the inner positioning part 32 to internally support the straight cylinder, thereby completing the center positioning of the straight cylinder.

[0061] In the third step, after the two internal positioning components 32 support and position the straight cylinder internally, the arc-shaped corrective plate 514 is pressed against the side wall of the straight cylinder. The motor 31 is first controlled to drive the rotating column 311 and the two internal positioning components 32 to rotate, so that the two internal positioning components 32 drive the straight cylinder to rotate. As the straight cylinder rotates, the arc-shaped corrective plate 514 corrects the side wall of the straight cylinder, and due to the rotation of the rotating column 311, the stabilizing plate 312 continues to rotate with it, thereby driving the arc-shaped corrective plate 514 to move back and forth left and right through the left-moving component 52, thereby increasing the corrective effect of the arc-shaped corrective plate 514 on the side wall of the straight cylinder, and at the same time, the lifting protrusion 517 pushes the lifting rod 516 upward, so that the arc-shaped corrective plate 514 swings back and forth, thereby further increasing the corrective effect of the arc-shaped corrective plate 514 on the side wall of the straight cylinder.

[0062] The fourth step, when the correction part 5 completes the correction of the side wall of the straight cylinder, the electric push rod 111 is controlled to push the orifice plate positioning part 2 and the orifice plate to the right, so that the orifice plate is inserted into the straight cylinder and combined with the straight cylinder. During the process of inserting the orifice plate into the straight cylinder, the pressure block 221 will return to the inner groove due to the pressure of the avoidance groove 313, and the pressing plate 332 will replace the pressure block 221 to limit the right side of the orifice plate, so that the orifice plate is always in a vertical state, and the rolling pressure of the rolling component 23 is balanced by the pressing plate 332.

[0063] The fifth step is to wait for the orifice plate and the straight cylinder to be combined, first control the welding machine 4 that avoids the combination of the orifice plate and the straight cylinder to perform preliminary welding on the contact position of the orifice plate and the straight cylinder, and then control the motor 31 again to drive the rotating column 311 and the two internal positioning components 32 to rotate, so that the two internal positioning components 32 drive the straight cylinder to rotate, and continue to weld the connecting part of the orifice plate and the straight cylinder through the welding machine 4 until the connecting part of the orifice plate and the straight cylinder is completely welded, then remove the positioning effect of the orifice plate positioning part 2 on the orifice plate, and then control the internal positioning component 32 to release the internal support of the straight cylinder, and finally remove the welded orifice plate and the straight cylinder together through an external device.
