Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and specifically provides a positioning and conveying device for processing building water supply pipes. Background Art

[0002] Building water supply pipes are pipe systems that supply water for life, production, etc. within buildings, and play a crucial role in construction projects. Commonly used pipe materials include plastic pipes, metal pipes, and composite pipes. In order to facilitate the connection and disassembly of pipes, flanges are usually welded to the ends of water supply pipes during the production process. The conveying equipment moves the pipes and flanges to the welding position respectively, uses an external clamping device to clamp the water supply pipes and flanges, and welds and fixes the two through a welding mechanism.

[0003] There are many traditional ways to fix flanges and water supply pipes, including roller conveyor, belt conveyor, and hoisting. In an automated production workshop, hoisting is one of the commonly used conveying methods, which can accurately move the water supply pipes and flanges to the processing position. After welding, the processed products are hoisted away, and then waiting for the hoisting mechanism to transport the products to the processing area again. However, the traditional belt conveyor cannot accurately move the water supply pipes and flanges to the position of the clamping device for fixation, and it also needs to cooperate with manual labor or other equipment, resulting in a relatively long overall time consumption and affecting the processing efficiency.

[0004] The positioning of pipes during welding is a very crucial link to ensure the welding quality. When welding two pipes, if the positioning is inaccurate, the situation of non - coaxial pipe centerlines is likely to occur; this will lead to uneven gaps at the welding joint, too large gaps in some areas, an increase in the amount of filler metal, and easy generation of welding defects such as incomplete penetration and weld bead. Traditional clamping devices are also difficult to ensure high accuracy when adjusting the height, which affects the welding quality. Summary of the Invention

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] To enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Figure 1 It is a positioning and conveying device for processing building water supply pipes, which is used in the process of welding water supply pipes and flanges. The welding equipment required is a circumferential welding equipment (not shown in the figure).

[0033] As Figure 1 and Figure 7 shown, there is a device on the loading conveyor rack 7 for driving the transmission of the loading belt 8 and capable of providing a supporting force for the loading belt 8. When the water supply pipe and the flange (hereinafter replaced by the product) are placed on the loading belt 8, as the loading belt 8 transmits, the product will gradually move to the area where welding is required. There is a transverse groove 9 on the loading belt 8. When the flange is placed on the loading belt 8, the raised edge of the flange will be stuck inside the transverse groove 9 to ensure that the flange is in a completely horizontal state. The flange and the water supply pipe are alternately placed on the loading belt 8; there are two unloading belts 19 on the unloading conveyor rack 18. A driving assembly is provided on the unloading conveyor rack 18, which can drive the two unloading belts 19 to rotate simultaneously, and a support plate 20 is arranged inside to provide a supporting force for the unloading belts 19. A certain gap is provided between the two unloading belts 19. The transmission directions of the loading belt 8 and the unloading belts 19 are the same. The purpose of the loading belt 8 is to load materials, and the purpose of the unloading belts 19 is to unload materials. The circumferential welding equipment is installed at the position between the loading conveyor rack 7 and the unloading conveyor rack 18.

[0034] As Figure 1 shown, a relatively long guide pipe 1 is assembled directly above the loading conveyor rack 7 and the unloading conveyor rack 18. When the product is placed on the loading belt 8, it is necessary to ensure that the guide pipe 1 can pass through its interior.

[0035] As Figure 9 and Figure 10 shown, in order to ensure that the guide pipe 1 can be stably assembled at a certain position, a supporting block 22 for support is installed inside it through a connecting rod 21. Grooves 23 matching the shape of the supporting block 22 are opened on both sides of the support plate 20, and there is also a space at the top of the inner wall of the groove 23 for the connecting rod 21 to rotate. Therefore, the bottom edge of the supporting block 22 is arc-shaped. When the connecting rod 21 rotates, the supporting block 22 can move out of the interior of the groove 23. It is necessary to ensure that the two supporting blocks 22 alternately support inside the groove 23. A through groove communicating with the outside is provided at the bottom of the guide pipe 1 to ensure that when the connecting rod 21 rotates, the supporting block 22 can be retracted into the interior of the guide pipe 1.

[0036] As Figure 2As shown in the figure, the surface of the guiding tube 1 is installed with a roller frame 10 through a guiding rod. The rotation direction of the rollers on the roller frame 10 is the same as the transmission direction. A connecting spring 11 is sleeved on the guiding rod. The two ends of the connecting spring 11 are respectively fixed on the surface of the roller frame 10 and the guiding tube 1. The roller frame 10 is used to provide a supporting force for the guiding tube 1 to ensure that the guiding tube 1 has the roller frame 10 and a supporting block 22 to provide stable support in different states. When the guiding tube 1 passes through the product, the edge of the product will squeeze the roller frame 10, and the connecting spring 11 will be compressed until the roller frame 10 is completely inside the product.

[0037] Figure 1 In this state, the guiding tube 1 is supported by the roller frame 10 and the outermost supporting block 22, and the inner supporting block 22 is retracted into the inside of the guiding tube 1.

[0038] As Figure 1 、 Figure 7 and Figure 8 shown, when the feeding belt 8 drives the product to move, in order to ensure that the product can move to the accurate position for welding, a limiting component is assembled on the discharging conveying frame 18, including two limiting blocks 12 symmetrically arranged at the flange positions. When the flange abuts against the surface of the limiting block 12, it means that the product has accurately reached the welding area. The discharging conveying frame 18 is assembled with a U-shaped supporting frame one 13. The whole of the supporting frame one 13 is sleeved on the surface of the discharging conveying frame 18. A guiding ring is arranged on the side of the discharging conveying frame 18. The supporting frame one 13 passes through the inside of the guiding ring, and a supporting spring 16 is sleeved on the surface of the supporting frame one 13.

[0039] At the same time, in order to prevent the guiding tube 1 from moving along with the movement of the product, a movement blocking component is arranged at the end of the guiding tube 1. Refer to Figure 7 , the baffle 14 abuts against the end of the guiding tube 1. The discharging conveying frame 18 is assembled with a U-shaped supporting frame two 15. The whole of the supporting frame two 15 is sleeved on the surface of the discharging conveying frame 18. A guiding ring is arranged at the position of the discharging conveying frame 18 corresponding to the supporting frame two 15. The supporting frame two 15 passes through the inside of the guiding ring, and a supporting spring 16 is sleeved on the surface of the supporting frame two 15.

[0040] A rotatable extrusion rod 17 is installed below the discharging conveying frame 18. The extrusion rod 17 is driven to rotate by a motor (not shown in the figure). When the extrusion rod 17 rotates to squeeze the supporting frame one 13, the limiting block 12 moves upward away from the surface of the flange. At this time, the welded product moves to the area between the two supporting blocks 22. The extrusion rod 17 rotates to squeeze the supporting frame two 15. When the supporting frame one 13 loses the extrusion force, it will return to the initial position due to the resilience of the supporting spring 16 and continue to perform the limiting function. The supporting frame two 15 drives the baffle 14 to move upward away from the guiding tube 1, and the product will smoothly move out. Then the extrusion rod 17 returns to the horizontal state again.

[0041] As Figure 3 —Figure 6 As shown, a positioning assembly is installed inside the guide tube 1, including at least three T-shaped rods 2 in an annular array inside the guide tube 1. In the present embodiment, the number of T-shaped rods 2 is set to four, and the end of the T-shaped rod 2 movably passes through the guide tube 1, and an arc plate 3 for squeezing the water supply pipe and the inner wall of the flange is installed at the end, that is, the arc plate 3 can rotate at the end of the T-shaped rod 2, and the compression spring 4 is sleeved on the surface of the T-shaped rod 2, and one end is fixed to the inner wall of the guide tube 1. A movable cross bar 5 is assembled inside the guide tube 1 through a support frame, and the cross bar 5 is pushed by an electric push rod. A plurality of truncated cone-shaped extrusion blocks 6 are fixedly sleeved on the cross bar 5, and the extrusion blocks 6 are against the end of the T-shaped rod 2.

[0042] During the movement of the extrusion block 6, each T-shaped rod 2 is evenly extruded, and the extended distance of each T-shaped rod 2 is the same. When the arc plates 3 on the T-shaped rod 2 are all against the inner wall of the product, it indicates that the axis of the flange and the water supply pipe coincides with the axis of the extrusion block 6. Therefore, by using the T-shaped rod 2 to extrude the flange and the water supply pipe at the same time, the concentricity of the two can be guaranteed, thereby ensuring a higher welding quality.

[0043] like Figure 1 , Figure 7 and Figure 8 As shown, after welding is completed, the limit block 12 is removed, and the T-bar 2 returns to the initial position. The product will gradually fall onto the loading belt 8, and the subsequent products will squeeze the welded product until it falls on the unloading belt 19. Since the conveying speed of the unloading belt 19 is greater than the conveying speed of the loading belt 8, there will be a distance between the welded product and the product to be welded. When the welded product is completely moved between the two support blocks 22, the limit block 12 returns to the limited state and continues the next welding operation.

[0044] like Figure 9 and Figure 10 As shown, a special-shaped gear 26 having teeth in a partial area is installed inside the guide tube 1 through a rotating shaft, and gears 27 that can mesh with the special-shaped gear 26 are installed on both sides. When the special-shaped gear 26 rotates to mesh with one side, the other side is in a stationary state. The teeth of the special-shaped gear 26 are 1 / 4 of the entire circumference. A worm wheel 24 is also installed inside the guide tube 1 through a rotating shaft, and a connecting rod 21 is connected to the rotating shaft. The surface of the worm wheel 24 meshes with the worm 25. It is necessary to ensure that the lead angle of the worm 25 is smaller than the equivalent friction angle between the meshing gear teeth of the worm wheel 24 and the worm wheel 24 to prevent the worm wheel 24 from driving the worm 25 to reverse. A gear 28 is sleeved on the surface of the worm 25, and a gear 3 29 is meshed on the surface of the gear 28. A gear 3 29 is coaxially assembled with the gear 1 27, and the two gears 3 29 are connected by a transmission belt 30.

[0045] The initial state is Figure 9As shown, the special-shaped gear 26 rotates and first meshes with the gear one 27 at the left end. The gear one 27 rotates. Through the rotation of the transmission belt 30 and the two gears three 29, the gear two 28 is driven to rotate, thereby driving the worm 25 to drive the worm wheel 24 to rotate. The worm wheel 24 causes the connecting rod 21 to rotate through the rotating shaft, and the support block 22 returns to the inside of the groove 23. The special-shaped gear 26 continues to rotate. When it rotates and meshes with the gear one 27 at the right end, the above actions are repeated. The rotation of the connecting rod 21 causes the support block 22 to move away from the groove 23. It should be noted that in this embodiment, as long as it is ensured that the support block 22 at the left end rotates and enters the inside of the groove 23 first, and the support block 22 at the right end rotates and moves out, the helix direction of the worm 25 needs to meet this condition.

[0046] The present invention provides a positioning and conveying device for processing building water supply pipes. The flanges and the water supply pipes are alternately placed on the feeding belt 8. The guiding pipe 1 passes through the inside of the flanges and the water supply pipes. The raised edges of the flanges are placed inside the transverse grooves 9. The feeding belt 8 drives the flanges and the water supply pipes to move until the flanges abut against the surface of the limiting block 12. The extrusion block 6 moves and evenly extrudes each T-shaped rod 2. The extended distances of each T-shaped rod 2 are the same. When the arc-shaped plates 3 on the T-shaped rods 2 all abut against the inner walls of the products, it indicates that the axes of the products coincide with the axis of the extrusion block 6. Therefore, by using the T-shaped rods 2 to simultaneously extrude the flanges and the water supply pipes, the concentricity of the two can be ensured, ensuring a high welding quality. When the welding is completed, the extrusion rod 17 rotates to extrude the support frame one 13, and the limiting block 12 moves upward away from the surface of the flange. The extrusion block 6 moves back, and the resilience of the compression spring 4 drives the T-shaped rod 2 and the arc-shaped plate 3 back to the initial state. The products fall onto the feeding belt 8, and the subsequent products extrude the welded products until they fall onto the discharging belt 19. Since the conveying speed of the discharging belt 19 is greater than the conveying speed of the feeding belt 8, a distance will be generated between the welded products and the products to be welded. When the welded products completely move between the two support blocks 22, the extrusion rod 17 rotates away from the support frame one 13, and the resilience of the support spring 16 causes the support frame one 13 to drive the limiting block 12 back to the initial position. At the same time, the special-shaped gear 26 rotates and first meshes with the inner gear one 27. The gear one 27 rotates. Through the rotation of the transmission belt 30 and the two gears three 29, the gear two 28 is driven to rotate, thereby driving the worm 25 to drive the worm wheel 24 to rotate. The worm wheel 24 causes the connecting rod 21 to rotate through the rotating shaft, and the support block 22 returns to the inside of the groove 23. The special-shaped gear 26 continues to rotate. When it rotates and meshes with the outer gear one 27, the above actions are repeated. The connecting rod 21 is in a horizontal state, and the products are driven by the discharging belt 19 to move out. During the welding process, the extrusion rod 17 rotates to extrude the support frame two 15, and the support frame two 15 drives the baffle 14 to move upward away from the guiding pipe 1, and the products will move out smoothly. Then the extrusion rod 17 returns to the horizontal state again. Then the special-shaped gear 26 rotates in the reverse direction and returns to the previous state, and this is repeated continuously for transmission.
