Technical Field

[0001] This invention belongs to the field of pipe welding positioning technology, and in particular relates to a welding system for the manufacture of electromechanical equipment. Background Technology

[0002] Electromechanical equipment refers to equipment that combines the principles of mechanical engineering and electrical engineering. It usually refers to complex equipment used in industrial production, construction, transportation and other fields that can realize the combination of mechanical action and electrical control. During the manufacturing process of electromechanical equipment, materials such as pipes or plates are required. Welding equipment is required when connecting two pipes. The quality of welding is crucial to the overall performance of electromechanical equipment.

[0003] In existing technologies, the welding requirements between pipe fittings vary in different application scenarios. Some scenarios require concentric welding between two pipe fittings, while others require perpendicular welding. To ensure the welding quality between the two pipe fittings, precise positioning of the two pipe fittings is often required during the welding process. However, existing welding equipment for electromechanical equipment manufacturing typically has a relatively simple positioning function and cannot adapt to different pipe fitting positioning methods according to the usage requirements of different application scenarios, thus reducing the applicability of welding equipment for electromechanical equipment manufacturing.

The power shaft is fixedly connected to the rotating disk.

[0011] In this embodiment of the invention, an automatic material unloading box is provided above the horizontal guide platform. An installation frame is fixed on one side of the bearing frame relative to the fixed frame. The automatic material unloading box is fixedly connected to the installation frame. A material inlet is provided on one side of the automatic material unloading box near the top.

[0014] When it is necessary to achieve vertical contact positioning of pipe fitting 1 and pipe fitting 2, this invention controls the curved surface on the semi-circular guide cylinder to face the feed inlet side and drives the semi-circular guide cylinder to move downward to the set position. During the placement of pipe fitting 2, it slides along the semi-circular guide cylinder, so that pipe fitting 2 will not deflect during the movement. In this way, the positioning of each pipe fitting 2 during the automatic feeding process is achieved. During the control of the movement of pipe fitting 2, precise positioning with pipe fitting 1 can be achieved, which not only improves the positioning efficiency between different pipe fittings but also ensures the welding quality.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] For a specific implementation example, please refer to Implementation Example 1. Figures 1-11 The present invention is a welding system for manufacturing electromechanical equipment, including a welding material guiding mechanism 1, a pipe conveying mechanism 2, and a pipe positioning mechanism 3; the welding material guiding mechanism 1 includes a welding support platform 101 and a horizontal guide platform 102, a rotation limiting part 103 is provided on one side of the horizontal guide platform 102 along its length direction, an arc-shaped guide groove 104 is provided on the side of the welding support platform 101 opposite to the rotation limiting part 103, and a rotation driving part 105 is provided between the welding support platform 101 and the arc-shaped guide groove 104.

[0030] The pipe conveying mechanism 2 is slidably mounted on the top of the horizontal guide platform 102. The pipe conveying mechanism 2 includes a pipe pushing part coaxial with the welding support platform 101. A linkage part is fixed on one side of the pipe pushing part, which penetrates the inner cavity of the rotary drive part 105. That is, when the rotary drive part 105 rotates, it drives the pipe pushing part to move, thereby realizing the movement of the entire pipe conveying mechanism 2. A movable guide seat 201 adapted to the arc-shaped guide groove 104 is sleeved on the linkage part.

[0031] The pipe fitting positioning mechanism 3 is slidably mounted on the pipe fitting conveying mechanism 2, so that the pipe fitting positioning mechanism 3 moves synchronously with the pipe fitting conveying mechanism 2. The pipe fitting positioning mechanism 3 includes an inner support positioning part that moves telescopically along the axis of the pipe fitting pushing part. The inner support positioning part achieves the positioning of the pipe fitting 5 by supporting and clamping the inner wall of the second pipe fitting 5, so that the second pipe fitting 5 will not move when it moves with the pipe fitting positioning mechanism 3. The rotary drive part 105 is used to push the pipe fitting conveying mechanism 2 to make linear or curved movements, so as to achieve the horizontal positioning of the two pipe fittings 4 or the vertical positioning of the first pipe fitting and the second pipe fitting 5.

[0032] In this embodiment of the invention, such as Figure 7 and Figure 8 As shown, the welding material guiding mechanism 1 also includes a fixed frame 106 (the fixed frame 106 is installed on an external frame). A bearing frame 107 is fixedly installed on one side of the fixed frame 106. The welding bearing table 101 and the horizontal material guiding table 102 are fixedly installed inside the bearing frame 107. A limiting channel 108 is provided at the top of the horizontal material guiding table 102. A first motor 109 is installed on the side of the fixed frame 106 away from the bearing frame 107. The output shaft of the first motor 109 is connected to the rotary drive unit 105. The rotation of the rotary drive unit 105 is controlled by the first motor 109.

[0033] Furthermore, an electric push rod 110 is installed on the outer wall of the support frame 107. The movable end of the electric push rod 110 is connected to a limiting plate 111 that fits against the inner wall of the welding support table 101. The position of the limiting plate 111 inside the welding support table 101 is adjusted by the electric push rod 110, and the position of the limiting plate 111 can be adjusted according to actual needs. A connecting shaft is rotatably provided on the inner side of the horizontal guide table 102. A second motor 112 is installed on the outer wall of the horizontal guide table 102. The connecting shaft is connected to the output end of the second motor 112. The rotation limiting part 103 is fixedly installed on the connecting shaft. The arc-shaped guide groove 104 is provided on the side of the fixed frame 106 near the support frame 107. That is, the rotation of the rotation limiting part 103 is controlled by the second motor 112.

[0034] In this embodiment of the invention, such as Figure 9As shown, the pipe fitting pushing unit includes a pipe fitting support 202 with the same inner diameter as the welding support table 101. Since the pipe fitting support 202 is coaxial with the welding support table 101 during horizontal movement, the pipe fitting 4 conveyed by the pipe fitting support 202 can achieve precise contact and positioning with the pipe fitting 4 on the welding support table 101, thereby ensuring the welding quality of the two pipe fittings 4 in the horizontal direction. A pushing disk 203 is fixedly provided at one end of the pipe fitting support 202. An axial through-hole 204 coaxial with the pushing disk 203 is opened on the surface of the pushing disk 203. The bottom of the pipe fitting support 202 is fixed with a sliding engagement with the limiting channel 108. The movable base 205 slides along the length of the limiting channel 108 through the setting of the limiting channel 108. The rotating limiting part 103 achieves the limiting by rotating and fitting the movable base 205. During the horizontal movement of the pipe conveying mechanism 2, since the top of the movable base 205 is fitted and limited by the rotating limiting part 103, the movable base 205 can be limited within the limiting channel 108 and can only slide along the limiting channel 108. The bottom of the pipe support 202 is equipped with a third motor 206 through the mounting base, and the output end of the third motor 206 is connected to a horizontal screw 207.

[0035] Furthermore, the linkage includes a linkage rod 208 fixed on the outer wall of the pipe support 202. A sliding member 209 is fixed on the periphery of the linkage rod 208 and slidably fitted in the inner cavity of the rotary drive unit 105. A telescopic cylinder 211 is provided on the mounting plate 210 fixed on the periphery of the linkage rod 208. The movable guide seat 201 is slidably sleeved on the linkage rod 208 and connected to the output end of the telescopic cylinder 211. During the horizontal movement of the pipe conveying mechanism 2, the movable guide seat 201 is detached from the fixed frame 106 under the connection action of the telescopic cylinder 211 (i.e., the movable guide seat 201 is between the fixed frame 106 and the bearing frame 107). During this process, the top of the movable base 205 is fitted and limited by the rotation limiting part 103.

[0036] When it is necessary to achieve the abutment positioning of two pipe fittings 4 in the horizontal direction, first place one pipe fitting 4 on the welding support table 101 and make it fit with the limiting plate 111, then place the other pipe fitting 4 on the pipe fitting support 202 and make it fit with the pushing plate 203. At this time, the positions of each mechanism in the entire equipment are as follows: Figure 1 and Figure 2 As shown, the first motor 109 is then started to drive the rotary drive unit 105 to rotate counterclockwise (as shown). Figure 1As shown, during the rotation of the rotary drive unit 105, the sliding member 209 moves synchronously. Since the top of the moving base 205 is limited by the rotation limit part 103, the entire pipe conveying mechanism 2 moves horizontally towards the welding support table 101 during the rotation of the rotary drive unit 105 until the pipe 4 on the pipe support 202 and the pipe 4 on the welding support table 101 are in contact. Since the ends of the two pipe 4 to be welded are tightly abutted together, the butt joint between the two pipe 4 is a tight weld joint. In this way, the two pipe 4 are accurately positioned in the horizontal direction. Then, the tight weld joint can be welded (spot welding or other welding). After the welding of a set of pipe 4 is completed, the first motor 109 is started again to drive the rotary drive unit 105 to rotate clockwise to complete the reset. At the same time, the welded pipe is removed from the welding support table 101. The batch positioning welding of pipe 4 can be realized by following the same control method as above.

[0037] Specific embodiment two, based on specific embodiment one, such as Figure 3 As shown, the pipe positioning mechanism 3 also includes a support frame 301. The support frame 301 extends to one side of the limiting channel 108 and is fixed with an internally threaded pipe 302. The internally threaded pipe 302 is sleeved on the horizontal screw 207 and the two are threaded together. The bottom of the pipe support 202 is provided with a limiting guide groove that slides with the support frame 301. Through the above specific structural design, when the third motor 206 is started to drive the horizontal screw 207 to rotate, the support frame 301 can be driven to slide along the limiting guide groove at the bottom of the pipe support 202 by means of the cooperation between the horizontal screw 207 and the internally threaded pipe 302. In this way, the horizontal position adjustment of the entire pipe positioning mechanism 3 on the pipe support 202 can be realized. The output end of the positioning motor 303 installed on one side of the support frame 301 is connected to the power shaft 304. Several support rods 305 arranged around the power shaft 304 are fixed inside the support frame 301.

[0038] Furthermore, the inner support positioning part includes a support plate 306 fixed to the support rod 305 and cooperating with the axial opening 204. The outer diameter of the support rod 305 is the same as the diameter of the support plate 306. In the initial state, the support plate 306 fits exactly inside the axial opening 204. The support plate 306 has several radially arranged channels in a circumferential array inside. The side of the support plate 306 near the support rod 305 has a radial slide that communicates with the radial channels. An inner support positioning member 307 (whose inner support surface is an anti-slip structure) is slidably installed inside the radial channels. A rotating disk 308 is rotatably installed on the side of the support plate 306 near the support rod 305. The surface of the rotating disk 308 has eccentric slides 30 that correspond one-to-one with the radial slides. 9. The inner support positioning member 307 has a force-bearing rod 310 that passes through the radial slide and the eccentric slide 309 in sequence. The power shaft 304 is fixedly connected to the rotating disk 308. In the initial state, the inner support positioning member 307 is fitted in the corresponding radial cavity. When the positioning motor 303 is started to drive the power shaft 304 to rotate, the rotating disk 308, which rotates synchronously with the power shaft 304, drives the circumferentially arranged force-bearing rods 310 to slide outward along the eccentric slide 309. The force-bearing rods 310 are pushed outward along the radial slide by the eccentric slide 309. In this way, the circumferentially arranged inner support positioning members 307 move outward synchronously and extend out of the radial cavity.

[0039] When it is necessary to achieve vertical contact positioning of fitting 4 and fitting 5, first place fitting 4 on the welding support platform 101 and attach it to the limiting plate 111. Then place fitting 5 on the fitting support 202 and attach it to the pushing plate 203. Subsequently, start the third motor 206 to drive the horizontal screw 207 to rotate. With the cooperation between the horizontal screw 207 and the internal threaded pipe 302, drive the support frame 301 to slide along the limiting guide groove at the bottom of the fitting support 202 to the set position, so that the support plate 306 disengages from the axial port 204 and enters the interior of fitting 5. Then, drive the power shaft 304 to rotate through the positioning motor 303. Under the rotation of the rotating plate 308, drive the circumferentially arranged fittings 4 and 5 to rotate. Each inner support positioning member 307 moves outward synchronously and extends into the radial cavity until each inner support positioning member 307 is tightly pressed against and supported on the inner wall of the second pipe fitting 5. This achieves the inner support positioning of the second pipe fitting 5 on the pipe fitting support 202. Then, the first motor 109 is started to drive the rotary drive unit 105 to rotate counterclockwise. During the rotation of the rotary drive unit 105, the sliding member 209 moves synchronously. Since the top of the movable base 205 is fitted and limited by the rotary limiting part 103, the entire pipe fitting conveying mechanism 2 moves horizontally towards the welding support table 101 during the rotation of the rotary drive unit 105 until the movable guide seat 201 moves to the set position. At this time, the movable guide seat 201 is concentrically aligned with the arc-shaped guide groove 104 (e.g., Figure 5 and Figure 6As shown), after the movable guide seat 201 is driven to move and engage with the arc-shaped guide groove 104 by the telescopic cylinder 211, the second motor 112 is started to control the rotation limiting part 103 to rotate counterclockwise by a certain angle, so that the rotation limiting part 103 releases its contact limiting on the top of the movable base 205 (as shown). Figure 7 As shown), the first motor 109 then drives the rotary drive unit 105 to rotate counterclockwise, causing the movable guide seat 201 to slide upwards along the arc-shaped guide groove 104 until the pipe conveying mechanism 2 rotates to a vertical position. At this time, the curved notch at the end of the second pipe 5 is arranged vertically downwards. Then, the third motor 206 is started again to drive the horizontal screw 207 to rotate, so that the second pipe 5, which is clamped and fixed by each inner support positioning part 307, continues to move downwards until the curved notch at the bottom of the second pipe 5 precisely fits onto the outer wall of the first pipe 4. Since the second pipe 5 is tightly fitted onto the first pipe 4, the butt joint between the second pipe 5 and the first pipe 4 is a tight weld joint. In this way, the precise positioning of the second pipe 5 and the first pipe 4 in the vertical direction is achieved. Then, the tight weld joint can be welded (spot welding or other welding).

[0040] After welding fittings 25 and 4 is completed, the positioning motor 303 is started to drive the power shaft 304 to rotate in the opposite direction. Under the rotation of the rotating disk 308, the circumferentially arranged inner support positioning parts 307 are driven to retract synchronously into the radial cavity. This releases the inner support clamping of the inner support positioning parts 307 on the inner wall of fitting 25. Then, the third motor 206 is started to drive the horizontal screw 207 to rotate in the opposite direction, causing the support disk 306 to move upward until it is reset. At this time, the support disk 306 re-fits into the axial port 204. The support plate 306 detaches from the pipe fitting 2 5, and the first motor 109 is restarted to drive the rotary drive unit 105 to rotate clockwise, causing the pipe fitting conveying mechanism 2 to rotate from a vertical state to a horizontal state (at this time, the moving base 205 re-fits into the limiting channel 108). During this process, the welded T-shaped pipe fitting is removed. Then, the second motor 112 is started to control the rotary limiting unit 103 to rotate clockwise by a certain angle, causing the rotary limiting unit 103 to reset. At this time, the rotary limiting unit 103 re-fits and limits the top of the moving base 205 (e.g., ...). Figure 7 As shown), the movable guide seat 201 is then driven to move in the opposite direction by the telescopic cylinder 211 to disengage from the arc-shaped guide groove 104 and return to the initial position. Then, the rotary drive unit 105 is driven to rotate clockwise again until the pipe conveying mechanism 2 completes the reset. Subsequently, the batch positioning welding of pipe fitting 2 5 and pipe fitting 1 4 can be realized by following the same control method.

[0041] Specific embodiment three, based on specific embodiment two, such as Figure 7 and Figure 8As shown, an automatic material drop box 113 is provided above the horizontal guide table 102. A mounting frame 114 is fixed to one side of the support frame 107 relative to the fixed frame 106. The automatic material drop box 113 is fixedly connected to the mounting frame 114. A feed inlet 115 is provided on one side of the automatic material drop box 113 near the top. Pipe fitting 2 5 or pipe fitting 4 can be placed into the automatic material drop box 113 through the feed inlet 115. The bottom of the automatic material drop box 113 is provided with an arc-shaped channel 116 with the same diameter as the pusher plate 203. A first hydraulic cylinder is installed on one side of the horizontal guide table 102. 117. The output end of the first hydraulic cylinder 117 is connected to an arc-shaped baffle 119 via a support plate 118. The outer diameter of the arc-shaped baffle 119 is the same as the diameter of the arc-shaped channel 116. The arc-shaped baffle 119, the arc-shaped channel 116, the pusher plate 203, and the welding support table 101 are arranged coaxially. This ensures that when the first hydraulic cylinder 117 controls the arc-shaped baffle 119 to move towards the inside of the automatic material box 113, the arc-shaped baffle 119 can smoothly slide into the arc-shaped channel 116 to support the pipe fitting 2 5 or pipe fitting 4 at the bottom of the arc-shaped channel 116.

[0042] In this embodiment of the invention, such as Figure 3 , Figure 4 and Figure 11As shown, the present invention also includes a material dropping guide mechanism 6; wherein, the material dropping guide mechanism 6 includes a lifting frame 601 slidably sleeved on the mounting frame 114, a semi-circular guide cylinder 602 rotatably provided at the bottom of the lifting frame 601, a steering motor 603 connected to the semi-circular guide cylinder 602 installed on the inner side of the lifting frame 601, a guide opening 604 with the same diameter as the arc-shaped channel 116 at the bottom of the semi-circular guide cylinder 602, and a second hydraulic cylinder (not shown in the figure) connected to the lifting frame 601 at the top of the mounting frame 114, when it is necessary to achieve horizontal direction When the two pipe fittings 4 are positioned in contact, the flat surface on the semi-circular guide cylinder 602 in the initial state faces the feed inlet 115, and the pipe fitting support 202 in the initial state is exactly located in the arc-shaped channel 116 at the bottom of the automatic feeding box 113. The guide opening 604 at the bottom of the semi-circular guide cylinder 602 is completely inside the automatic feeding box 113. In this way, a certain number of pipe fittings 4 can be placed into the automatic feeding box 113. The pipe fitting 4 at the bottom of the automatic feeding box 113 fits on the pipe fitting support 202. When the pipe fitting is driven to convey As mechanism 2 moves toward welding support platform 101, the first hydraulic cylinder 117 controls the arc-shaped baffle 119 to gradually move toward the inside of automatic material drop box 113 to a set position. This allows the arc-shaped baffle 119 to support the bottom pipe fitting 4 of the automatic material drop box 113 to prevent it from falling. Simultaneously, when the pipe fitting conveying mechanism 2 is driven to move, causing the pipe fitting support 202 to re-enter the inside of the arc-shaped channel 116, the pusher disc 203 contacts the arc-shaped baffle 119 to trigger the pressure sensor on the pusher disc 203. The device controls the arc-shaped baffle 119 to move in the opposite direction through the first hydraulic cylinder 117 until it is reset (the movement rhythm of the pipe support 202 and the arc-shaped baffle 119 is consistent). At this time, the pipe support 202 is again located in the arc-shaped channel 116 at the bottom of the automatic feeding box 113. The lowest pipe 4 in the automatic feeding box 113 falls into the pipe support 202. In this way, the automatic feeding of pipe 4 in the welding positioning process is realized, thereby improving the welding positioning efficiency of the two pipes 4 in the horizontal direction.

[0043] When it is necessary to achieve vertical contact positioning between pipe fitting 4 and pipe fitting 5, first start the steering motor 603 to control the semi-circular guide cylinder 602 to rotate 180°, so that the curved surface on the semi-circular guide cylinder 602 faces the feed inlet 115, and the pipe fitting support 202 in the initial state is just located in the arc-shaped channel 116 at the bottom of the automatic feeding box 113, and the guide port 604 at the bottom of the semi-circular guide cylinder 602 is completely inside the automatic feeding box 113. Then, the second hydraulic cylinder drives the semi-circular guide cylinder 602 to move downward to the set position. At this time, the bottom of the semi-circular guide cylinder 602 is close to the horizontal guide table 102, so that a certain number of pipe fittings 5 ​​can be placed. 5 is placed into the automatic feeding box 113. The bottom pipe fitting 5 of the automatic feeding box 113 fits onto the pipe fitting support 202. During the placement of pipe fitting 5, it slides along the semi-circular guide cylinder 602, so that pipe fitting 5 will not deflect during the movement. This achieves the positioning of each pipe fitting 5 during the automatic feeding process. After the inner wall of the pipe fitting 5 on the pipe fitting support 202 is positioned, the semi-circular guide cylinder 602 is driven upward by the second hydraulic cylinder to complete the reset. When the pipe fitting conveying mechanism 2 is driven to move towards the welding support table 101, the arc-shaped baffle 119 is controlled by the first hydraulic cylinder 117. The pipe gradually moves towards the inner side of the automatic feeding box 113 to the set position. This allows the arc-shaped baffle 119 to support the bottom pipe component 5 of the automatic feeding box 113 to prevent it from falling. When the pipe conveying mechanism 2 is driven to move, causing the pipe support 202 to re-enter the inner side of the arc-shaped channel 116 (the pusher disc 203 contacts the arc-shaped baffle 119 to trigger the pressure sensor on the pusher disc 203), the first hydraulic cylinder 117 controls the arc-shaped baffle 119 to move in the opposite direction (the movement rhythm of the pipe support 202 and the arc-shaped baffle 119 is kept consistent, ensuring that the pusher disc 203 does not detach from the arc-shaped baffle 119). When the pipe component is supported... When the end of seat 202 away from push plate 203 moves to the set position inside arc channel 116, the second hydraulic cylinder drives the semi-circular guide cylinder 602 to move downward to the set position. At this time, the bottom of the semi-circular guide cylinder 602 is close to the horizontal guide table 102. Then, the pipe support seat 202 and arc baffle 119 continue to move synchronously until the reset is completed. The lowest pipe 2 5 in the automatic dropping box 113 falls into the pipe support seat 202 along the semi-circular guide cylinder 602. In this way, the automatic feeding of pipe 2 5 in the welding positioning process is realized, thereby improving the welding positioning efficiency of pipe 1 4 and pipe 2 5 in the vertical direction.
