Description

Technical Field

[0001] This invention relates to the field of electromechanical installation technology, specifically a welding positioning table for electromechanical installation. Background Technology

[0002] Welding positioning tables for electromechanical installation are high-precision tool tables specifically designed for the installation and welding of electromechanical equipment. They are intended to accurately position and fix electromechanical components or structural parts, thereby ensuring the stability of the workpiece during welding, assembly and other processes, and avoiding welding errors caused by offset. However, existing welding positioning tables still have certain defects in practical applications. In particular, during the welding process, the workpiece is prone to offset, resulting in insufficient alignment accuracy, which in turn affects the welding quality.

[0003] To overcome the aforementioned deficiencies, prior art 1 (Chinese patent with publication number CN219925032U, publication date October 31, 2023) discloses a welding positioning component for electromechanical installation, relating to the field of electromechanical and related equipment technology. This patent includes a base, with receiving grooves on both sides of the upper surface of the base. An extension component is installed inside the receiving groove. Clamping components are provided on both sides of the upper surface of the base. Rotating components are provided at both the front and rear ends of the top two sides of the base. Through the rotating components and the extension components, the unwelded portion of the electromechanical pipe can be adjusted to the top, facilitating welding by workers, increasing work efficiency, reducing labor intensity, and allowing for adjustment of the support position according to the length of the electromechanical pipe, enabling welding of pipes of different lengths. It has a wide range of applications. There is also prior art 2 (application number CN221415). (Chinese Patent 575U, filed on July 26, 2024) A welding positioning assembly for electromechanical installation, relating to the field of positioning assembly technology, further includes: a support plate, with clamping mechanisms connected to both sides of the top of the support plate via screw transmission components. The clamping mechanism includes a connecting plate, a sliding rod slidably connected to one side of the connecting plate, a first clamping plate for clamping the base fixedly connected to one end of the sliding rod, a spring fixedly connected to the side of the first clamping plate near the sliding rod, one end of the spring fixedly connected to one side of the connecting plate, a through groove opened on one side of the connecting plate, a connecting rod on one side of the through groove containing a movable block, and a second clamping plate for clamping the electromechanical equipment fixedly connected to one end of the connecting rod. By setting up the clamping mechanism, it is possible to quickly clamp and position the electromechanical equipment and the base to be welded even if they are not exactly the same size, without requiring repeated adjustments by the operator, thereby improving the flexibility of the assembly during use.

[0004] Existing technologies use clamping structures to limit the position of workpieces, effectively preventing them from shifting during welding. However, the complex clamping structures not only increase overall production and maintenance costs, but also lack sufficient adaptability when handling non-standard or special-sized workpieces, resulting in poor clamping stability and affecting the smooth progress of the welding process. Furthermore, the adjustment structure on the clamping plate requires manual adjustment of the screws by the operator, which is time-consuming and lacks flexibility, resulting in a low overall level of automation. To address these issues, there is an urgent need for innovative design based on the existing welding positioning table for electromechanical installation. Therefore, we propose a welding positioning table for electromechanical installation that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a welding positioning table for electromechanical installation, in order to solve the problems mentioned in the background art. Currently, the existing clamping structure limits the workpiece and effectively prevents the workpiece from shifting during the welding process. However, the complex clamping structure not only increases the overall production and maintenance costs, but also lacks sufficient adaptability when handling non-standard or special-sized workpieces, resulting in poor clamping stability, which affects the smooth progress of the welding process. Furthermore, the adjustment structure on the clamping plate requires the operator to manually adjust the screw, which is time-consuming and lacks flexibility, resulting in a low overall level of automation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding positioning table for electromechanical installation, comprising a welding table, a movable plate connected inside the welding table via a drive assembly, a temporary storage box connected to the movable plate, a limit rod connected inside the temporary storage box via a first spring, the limit rod extending through the outside of the temporary storage box, an electromagnetic block installed inside the temporary storage box, a magnetic block provided on the side end of the electromagnetic block, a slot provided on the limit rod, a locking rod adapted to the slot connected to the side end of the magnetic block, a second spring sleeved on the outside of the locking rod, the limit rod abutting against a metal surface, at which time the first spring inside the temporary storage box rebounds, causing the limit rod to move. The limit rod can be effectively adjusted according to the shape of irregular metal, improving the overall automation level and reducing the cost increase caused by complex structures.

[0007] Preferably, the drive assembly includes a motor installed inside the welding station, the output end of the motor is connected to a positive and negative screw, the positive and negative screw is connected through the inside of the moving plate, the inside of the moving plate is connected through a first guide rod, and the positive and negative screw and the first guide rod are arranged parallel to each other.

[0008] Preferably, the limiting rod has a through hole that communicates with the inner cavity of the limiting rod, and a first pipe is provided on the outside of the through hole.

[0009] Preferably, a negative pressure hole is provided at the end of the limiting rod, and the negative pressure hole is connected to the inner cavity of the front section of the limiting rod. A piston is provided inside the inner cavity of the front section of the limiting rod. The piston draws the gas in the inner cavity of the front end of the limiting rod, so that the negative pressure hole at the end of the limiting rod can generate negative pressure with the surface of the irregular metal, thereby making the limiting of the irregular metal more stable and effectively preventing the metal from shifting due to vibration and other factors during the welding process.

[0010] Preferably, the inner cavity of the rear section of the limiting rod is connected to a nozzle through a first pipe, and a support seat is provided on the moving plate. The nozzle is located on the support seat, and the gas is sprayed out through the nozzle on the support seat. This not only facilitates the cleaning of the weld seam, removes impurities and oxides from the welded area, and improves the welding success rate, but also facilitates cooling after welding, accelerates the cooling and forming of the weld seam, and improves the precision and strength of the welded metal.

[0011] Preferably, a pusher plate is provided on the side of the movable plate, a water storage box is provided inside the welding table, the pusher plate is located inside the water storage box, and a cooling box is connected to the inside of the water storage box through a second pipe. The cooling box is connected to the upper side of the welding table through a movable component. The pusher plate on the side of the movable plate squeezes the liquid inside the water storage box into the second pipe, and then transports it to the cooling box through the second pipe. The cooling box moves to the surface of the irregular metal, which facilitates heat adsorption at the welding point with the irregular metal, avoids overheating of the metal affecting its performance, and improves the overall welding effect.

[0012] Preferably, the moving component includes a buffer installed under the cooling box, a rack connected to the bottom of the buffer, a gear meshing with the bottom of the rack, and a threaded rod penetrating through the inside of the gear.

[0013] Preferably, the outer side of the threaded rod is connected to the inside of the sleeve via ball bearings, and the sleeve is connected to the side end of the moving plate. The cooling box moves to the welded metal surface with the cooperation of the second guide rod. The buffer component facilitates the effective adjustment of the cooling box according to the metal thickness, thereby greatly improving the cooling efficiency of the cooling box and reducing the cumbersome problem caused by the need for manual operation of the cooling structure.

[0014] Preferably, a second guide rod is provided on the upper surface of the welding platform, and the side end of the cooling box is connected to the second guide rod through a guide block.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: In this electromechanical installation welding positioning table, because the side of the irregularly shaped metal abuts against the limiting rod, the limiting rod abuts against the metal surface. At this time, the first spring inside the temporary storage box rebounds, causing the limiting rod to move. The limiting rod can be effectively adjusted according to the shape of the irregularly shaped metal, improving the overall automation level. It can flexibly adapt to metals of different shapes, improving overall adaptability, and ensures the stable fixation of the limiting rod after positioning, reducing the problem of increased costs caused by complex structures. The specific details are as follows:

[0016] When the limit rod touches the metal surface, the first spring inside the temporary storage box rebounds, causing the limit rod to move. The limit rod can be effectively adjusted according to the shape of the irregular metal, which improves the overall level of automation and reduces the problem of increased costs caused by setting up complex structures.

[0017] The piston draws in the gas from the inner cavity at the front end of the limiting rod, which facilitates the generation of negative pressure between the negative pressure hole at the end of the limiting rod and the surface of the irregular metal, thereby making the limiting of the irregular metal more stable and effectively preventing the metal from shifting due to vibration and other factors during the welding process.

[0018] Gas is ejected through the nozzle on the support base, which not only facilitates the cleaning of the weld seam, removes impurities and oxides from the weld area, and improves the welding success rate, but also facilitates cooling after welding, accelerates the cooling and forming of the weld seam, and improves the precision and strength of the welded metal.

[0019] The pusher plate on the side of the moving plate squeezes the liquid inside the water storage box into the second pipe, and then transports it to the cooling box through the second pipe. The cooling box moves to the surface of the irregular metal, which facilitates heat adsorption at the welding point of the irregular metal, avoids overheating of the metal affecting its performance, and improves the overall welding effect.

[0020] The cooling box moves to the welded metal surface with the help of the second guide rod. The buffer device makes it easy to adjust the cooling box effectively according to the metal thickness, thereby greatly improving the cooling efficiency of the cooling box and reducing the cumbersome problem caused by the need for manual operation of the cooling structure.

Detailed Implementation

[0032] 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.

[0033] Example 1: In this example, the limiting rod 7 on the side of the temporary storage box 6 contacts the irregularly shaped metal. The entire assembly not only adapts to standard metals, but the limiting rod 7 can also be effectively adjusted according to the shape of the irregularly shaped metal, improving the overall level of automation. Figures 1-6The technical solution shown includes a welding table 1, a movable plate 4 connected inside the welding table 1 via a drive assembly, a temporary storage box 6 connected to the movable plate 4, a limit rod 7 connected inside the temporary storage box 6 via a first spring 8, the limit rod 7 extending through the outside of the temporary storage box 6, an electromagnetic block 9 installed inside the temporary storage box 6, a magnetic block 10 provided on the side of the electromagnetic block 9, a slot 13 provided on the limit rod 7, a locking rod 11 adapted to the slot 13 connected to the side of the magnetic block 10, a second spring 12 sleeved on the outside of the locking rod 11, and a drive assembly including components mounted on the welding table. The welding table 1 contains an internal motor 2. The output of motor 2 is connected to a reversible screw 3, which is threaded through the interior of a movable plate 4. A first guide rod 5 is threaded through the interior of the movable plate 4, and the reversible screw 3 and the first guide rod 5 are arranged parallel to each other. When an irregularly shaped metal piece for electromechanical installation is placed on the surface of the welding table 1, the internal motor 2 is activated. Motor 2 drives the reversible screw 3 to rotate, facilitating the movement of the movable plate 4 on the reversible screw 3 in opposite directions or relative to each other through the cooperation of the first guide rod 5. This improves positioning accuracy and operational flexibility, and facilitates the movement of the movable plate 4. The temporary storage box 6 moves towards the side of the irregular metal. The overall movement is stable and the structure is simple, reducing the problem of reduced overall accuracy caused by setting multiple drives. At this time, the limiting rod 7 at the side of the temporary storage box 6 comes into contact with the irregular metal, and the electromagnetic block 9 is magnetically applied, so that the electromagnetic block 9 and the magnetic block 10 are attracted to each other. This facilitates the magnetic block 10 to drive the locking rod 11 to move out of the locking groove 13 of the limiting rod 7. Since the side of the irregular metal abuts against the limiting rod 7, the limiting rod 7 moves inside the temporary storage box 6 by the rebound force of the first spring 8. When the side of the irregular metal is limited by the limiting rod 7, When the magnetic force of the electromagnetic block 9 is disconnected, the locking rod 11 returns to its initial position via the second spring 12 on the outside, making it easy for the locking rod 11 to engage with the slot 13 of the limiting rod 7. This allows the limiting rod 7 to be effectively adjusted according to the shape of the irregular metal, improving the overall automation level. By moving the limiting rod 7, it can flexibly adapt to metals of different shapes, improving the overall adaptability. It can also ensure that the limiting rod 7 is stably fixed after positioning, ensuring that the metal position does not shift during the welding process. The overall structure is simple, reducing the problem of increased costs caused by setting up complex structures.

[0034] Example 2: In this example, gas is ejected through the nozzle 18 on the support 19, which not only facilitates cleaning of the weld seam, removing impurities and oxides from the weld area and improving the welding success rate, but also facilitates post-weld cooling, accelerates weld cooling and shaping, and reduces thermal deformation. Specifically, as follows... Figures 3-8As shown, the following is disclosed: a through hole 14 is provided on the limiting rod 7, which is connected to the inner cavity of the limiting rod 7. A first pipe 15 is provided on the outside of the through hole 14. A negative pressure hole 17 is provided at the end of the limiting rod 7, which is connected to the inner cavity of the front section of the limiting rod 7. A piston 16 is provided inside the inner cavity of the front section of the limiting rod 7. A nozzle 18 is connected to the inner cavity of the rear section of the limiting rod 7 through the first pipe 15. A support base 19 is provided on the moving plate 4, and the nozzle 18 is located on the support base 19. A push plate 20 is provided on the side end of the moving plate 4. A water storage box 21 is provided inside the welding table 1, and the push plate 20 is located inside the water storage box 21. A cooling box 23 is connected to the inside of box 21 via a second pipe 22. The cooling box 23 is connected to the upper side of welding table 1 via a moving assembly. Gas is introduced into the limiting rod 7 through the cooperation of the first pipe 15 and the through hole 14 on the limiting rod 7. The piston 16 is positioned in a stop block and moves. The stop block has the same diameter as the inner cavity of the limiting rod 7. At this time, the gas is blocked by the stop block, thereby causing the piston 16 inside the limiting rod 7 to move, which facilitates the suction of gas from the inner cavity at the front end of the limiting rod 7. The negative pressure hole 17 at the end of the limiting rod 7 generates negative pressure with the surface of the irregular metal, thereby making the limiting of the irregular metal more stable and effectively preventing over-welding. During the process, the metal shifts due to vibration and other factors, improving welding quality. Gas is transported through the first pipe 15 and the through-hole 14, and ejected through the nozzle 18 on the support 19. This not only facilitates cleaning of the weld seam, removing impurities and oxides and increasing the welding success rate, but also facilitates post-weld cooling, accelerating weld formation, reducing thermal deformation, and improving the precision and strength of the welded metal. Both the support 19 and the temporary storage box 6 are moved by the movable plate 4, facilitating synchronized positioning and cleaning, as well as material unloading and cooling, improving work efficiency. Furthermore, by introducing cooler gas into the first pipe 15, it is not only convenient to push the piston 16 to generate negative pressure in the inner cavity of the front end of the limit rod 7, but also convenient for the cooler gas to be sprayed out through the nozzle 18 for cooling. When the moving plate 4 moves to both sides, the push plate 20 at the side end of the moving plate 4 squeezes the liquid inside the water storage box 21 into the second pipe 22, and then transports it to the cooling box 23 through the second pipe 22. The cooling box 23 moves to the surface of the irregular metal, which facilitates the absorption of heat at the welding point with the irregular metal, thereby performing a cooling operation, avoiding overheating of the metal and affecting its performance, and improving the overall welding effect.

[0035] Example 3: In this example, the buffer 29 facilitates effective adjustment of the cooling box 23 according to the metal thickness, thereby greatly improving the cooling efficiency of the cooling box 23. Specifically, as follows... Figures 3-10As shown, the movable assembly includes a buffer 29 installed under the cooling box 23. A rack 28 is connected to the bottom of the buffer 29, and a gear 27 is meshed with the bottom of the rack 28. A threaded rod 26 is connected through the inside of the gear 27. The outside of the threaded rod 26 is connected to the inside of a sleeve 24 via balls 25. The sleeve 24 is connected to the side of the movable plate 4. A second guide rod 30 is provided on the upper surface of the welding table 1. The side of the cooling box 23 is connected to the second guide rod 30 via a guide block. When the movable plate 4 moves, it drives the sleeve 24 to move, which facilitates the balls 25 inside the sleeve 24 to drive the internal threaded rod 26 to rotate. This causes the threaded rod 26 to drive the gear 27 to rotate, which in turn drives the rack 28 meshing with the upper end to move. The rack 28 is connected to the bottom of the cooling box 23 via the buffer 29, and the end of the cooling box 23 is arc-shaped. Therefore, the cooling box 23 can be moved to the welding metal surface through the cooperation of the second guide rod 30. At this time, the buffer 29 can be effectively adjusted according to the metal thickness. The buffer 29 can cooperate with the cooling box 23 on the arc-shaped side to move the cooling box 23 to the welding position, thereby greatly improving the cooling efficiency of the cooling box 23. Through water cooling heat absorption, the overall cooling efficiency is improved. Furthermore, the secondary cooling through air cooling and water cooling greatly improves the overall welding effect. This not only reduces the problem of the irregular metal becoming brittle due to direct contact of cooling water with the welding position, but also reduces the cumbersome problem of manual operation of the cooling structure, improving the degree of automation and cooling effect. At this time, the clamping and air cooling structure are removed, which facilitates the removal of the water-cooled metal, thereby improving the overall material unloading efficiency.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
