Description

Technical Field

[0001] This invention relates to the field of welding, and in particular to a welding and butt welding device for the production of alloy faucets. Background Technology

[0002] In the production of alloy faucets, welding is one of the core processes. It is mainly used to connect and fix the faucet body with pipe fittings such as the inlet pipe and the outlet bend to form a complete finished faucet. To ensure accurate positioning of the workpiece during welding, existing technologies generally use shaping fixtures to clamp and fix the alloy faucet body and the pipe fittings to be welded. The inner shape of this type of shaping fixture is perfectly adapted to the shape of the alloy faucet body, which can achieve stable clamping of irregularly shaped faucet bodies and avoid large shaking during welding.

[0003] However, existing shaping fixtures have significant technical defects in actual use, seriously affecting welding accuracy and product qualification rate. Specifically, welding operations generate a large amount of welding slag, which splashes under the high temperature of welding and easily adheres to and accumulates on the inside of the shaping fixture. Since the alloy faucet body has an irregular shape, the inner side of the matching shaping fixture inevitably has many pits, corners, and gaps corresponding to the shape of the faucet, forming many cleaning dead corners. Even if the inside of the fixture is cleaned after each welding, it is difficult to completely remove the welding slag, metal debris, and other impurities attached to the dead corners, and the impurities will continue to remain on the inside of the fixture.

[0004] During subsequent welding operations, when the operator places the new alloy faucet body into the shaping fixture for positioning and alignment, residual welding slag and impurities are trapped between the faucet body and the inside of the fixture, slightly lifting the faucet body and causing a minor deviation in the initially aligned alignment. More importantly, during the welding process, the high temperature generated causes thermal expansion and contraction of the fixture and workpiece, while the vibration generated by the welding equipment is transmitted to the fixture and workpiece. Under this dual effect, the welding slag and impurities originally remaining inside the fixture will loosen and shift.

[0005] Due to the displacement of welding slag and impurities, the alloy faucet body, which was originally slightly lifted, loses its stable support and positioning, leading to displacement, tilting, or even slight rotation. This causes a change in the relative welding position between the faucet body and the pipe fitting to be welded. This displacement deviation during the welding process can cause problems such as weld eccentricity, misalignment, and uneven gaps. This not only affects the appearance quality of the faucet but also reduces the weld sealing performance, making it prone to leaks such as water and air during subsequent pressure testing. This significantly reduces the product qualification rate and increases production costs.

[0006] To address the aforementioned problems, a welding and joining device for the production of alloy faucets is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a welding and butt welding device for the production of alloy faucets, which solves the problems caused by displacement deviation during the welding process, such as weld eccentricity, misalignment, and uneven gaps. These problems not only affect the appearance quality of the faucet, but also lead to a decrease in the sealing performance of the weld, resulting in defects such as water leakage and air leakage during subsequent pressure testing, which significantly reduces the product qualification rate and increases production costs.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A welding and butt welding device for producing alloy faucets, characterized in that it includes a base, a welding machine fixedly connected to one side above the base, a first electric push rod fixedly connected to one side of the lower surface of the base, a first slide plate fixedly connected to the output end of the first electric push rod, an electric clamping plate fixedly connected to the upper surface of the first slide plate, and a second electric push rod fixedly connected to the lower surface of the base away from the first slide plate. The output end of the second electric push rod is equipped with an elastic mechanism, and a rotating mechanism is provided on one side of the elastic mechanism. A third electric push rod is provided above the elastic mechanism, and a shaping clamp is fixedly connected to the output end of the third electric push rod. A silicone rubber cleaning block is provided on the side of the rotating mechanism near the elastic mechanism; The elastic mechanism is used to create continuous air pressure on the inside of the shaping clamp to hold down impurities when the alloy faucet is held in the shaping clamp and moved toward the welding machine. The rotating mechanism is used to drive the silicone rubber cleaning block to rotate and clean the inner wall of the shaping clamp when the clamp is reset.

[0009] 1. Compared with the prior art, the beneficial effects of the present invention are as follows: when the shaping clamp moves laterally to the predetermined position, the first guide rod is driven upward by the guide groove, compressing the gas between the first push rod and the alloy faucet, forming a continuous and uniform strong air pressure acting on the impurities in the groove, thereby firmly pressing the impurities during the welding process, preventing them from moving due to vibration or thermal expansion and contraction, ensuring the stability of the initial welding position, and improving the welding qualification rate.

[0010] 2. This invention relies on the necessary movement of the shaping clamp to the welding position to generate strong pressure, thereby avoiding the oversight of forgetting to start the strong pressure process due to negligence in the operation process, ensuring that impurities can be automatically suppressed in each welding, and further improving the reliability of welding quality.

[0011] 3. After welding is completed, the second electric push rod continues to move, and the compression of the first elastic telescopic rod applies a continuous clamping force to the shaping clamp and the alloy faucet, thereby effectively compensating for the metal shrinkage generated during the welding cooling process, avoiding gaps, cracks or leaks in the weld due to shrinkage, and improving the welding quality.

[0012] 4. In the cooling stage, the first guide rod moves to point a of the second guide groove and then resets downward, so that the air pressure between the first push rod and the alloy faucet returns to normal and the clamping force is appropriately reduced. This allows for deformation space when the workpiece cools and shrinks, preventing weld cracking caused by rigid clamping and further ensuring welding quality.

[0013] 5. In this invention, when the shaping clamp is reset, a silicone rubber cleaning block is inserted into its inner side and driven to rotate by the spiral guide groove to rotate and scrape the inner wall of the shaping clamp, thereby reducing the impact of residual impurities on the clamping accuracy of subsequent workpieces and ensuring the cleanliness of the clamping surface.

[0014] 6. During the reset process, the present invention controls the reciprocating motion of the first guide rod through the fifth guide groove, drives the first push rod to push air upward to blow out the cleaned impurities, and then draws air downward to pull the silicone rubber cleaning block tightly against the inner wall of the shaping clamp, thereby achieving active blowing and cleaning of the clamping area. When idle, it forms a negative pressure seal to prevent impurities from entering. At the same time, the back-and-forth movement of gas in the air path also effectively reduces the risk of blockage of the air guide hole and reduces maintenance costs. Attached Figure Description

[0018] Please see Figures 1-8 The present invention provides a technical solution: a welding and joining device for producing alloy faucets, comprising a base 1, a welding machine 2, a first electric push rod 3, a first sliding plate 4, an electric clamping plate 5, a second electric push rod 6, an elastic mechanism 7, a rotating mechanism 8, a shaping clamping plate 9, a third electric push rod 10, and a silicone rubber cleaning block 11. The base 1 serves as the mounting carrier for the entire device, accommodating all working components and providing stable support for each mechanism. The welding machine 2 is fixedly connected to one side above the base 1 and is used for welding alloy faucets to water pipes. The first electric push rod 3 is fixedly connected to one side of the lower surface of the base 1 and is used to drive the first sliding plate 4 to move laterally. The first sliding plate 4 is fixedly connected to the output end of the first electric push rod 3 and is used to drive the electric clamping plate 5 to move. The electric clamping plate 5 is fixedly connected to the upper surface of the first sliding plate 4 and is used to clamp the water pipe to be welded. The second electric push rod 6 is fixedly connected to the side of the lower surface of the base 1 away from the first sliding plate 4 and is used to drive the elastic mechanism 7 to move laterally.

[0019] The elastic mechanism 7 is located at the output end of the second electric push rod 6. When the shaping clamp 9 clamps the alloy faucet and moves towards the welding machine 2, it forms a continuous air pressure on the inner side of the shaping clamp 9 to suppress impurities and prevent them from moving due to vibration or thermal expansion and contraction during the welding process. The rotating mechanism 8 is located on one side of the elastic mechanism 7. When the shaping clamp 9 is reset, it drives the silicone rubber cleaning block 11 to rotate and clean the inner wall of the shaping clamp 9. The third electric push rod 10 is located above the elastic mechanism 7. Its output end is fixedly connected to the shaping clamp 9. It drives the shaping clamp 9 to open and close to achieve clamping and releasing of the alloy faucet. The silicone rubber cleaning block 11 is located on the side of the rotating mechanism 8 close to the elastic mechanism 7. It is used to rotate and scrape the inner wall of the shaping clamp 9 under the drive of the rotating mechanism 8.

[0020] The elastic mechanism 7 includes a first elastic telescopic rod 714, a second sliding plate 71, a guide hole 72, a vent pipe 73, a vent hole 74, a vent groove 75, a first push rod 76, a spring 77, a first push plate 78, a bearing plate 79, a first guide groove 710, a first guide rod 711, a second guide groove 712, an exhaust hole 713, and a sealing strip 715. The first elastic telescopic rod 714 is fixedly connected to the output end of the second electric push rod 6 and is used to continue to compress after welding to provide a continuous clamping force to compensate for the metal shrinkage generated during the welding cooling process. The second sliding plate 71 is fixedly connected to the output end of the first elastic telescopic rod 714 and is fixedly connected to the shaping clamp 9 to drive the shaping clamp 9 to move laterally.

[0021] A guide hole 72 is provided on the inner side of the base 1. A duct 73 is slidably connected to the inner side of the guide hole 72. The upper end of the duct 73 is a flexible tube and the lower end is a rigid tube. The lower end of the duct 73 is fixedly connected to the fixed end of the first elastic telescopic rod 714, so that the duct 73 can move laterally synchronously with the first elastic telescopic rod 714. Multiple duct holes 74 communicating with the duct 73 are provided on the inner side of the shaping clamp 9. Multiple duct grooves 75 are provided on the outer side of the duct holes 74. The duct holes 74 and the duct grooves 75 cooperate to form a gas flow channel for uniformly transmitting air pressure to the shaping clamp. In each area inside the 9, the inner side of the air duct 73 is provided with a first push rod 76. The first push rod 76 has a cuboid shape and its outer side is in close contact with the inner side of the air duct 73 to ensure that the gas will not leak when the first push rod 76 slides inside the air duct 73. The lower end of the first push rod 76 is fixedly connected to a spring 77, and the lower end of the spring 77 is fixedly connected to a first push plate 78. The inner side of the first push plate 78 is provided with an exhaust hole 713 that communicates with the upper and lower surfaces of the first push plate 78 to balance the air pressure on the upper and lower sides of the first push plate 78 when the air pressure changes.

[0022] A support plate 79 is fixedly connected to the lower surface of the base 1 near the welding machine 2. A first guide groove 710 is formed on the outer surface of the support plate 79. A first guide rod 711, which is fixedly connected to the first push plate 78, is provided on the inner side of the first guide groove 710. The appearance of the first guide groove 710 away from the welding machine 2 is a horizontal straight line, and the appearance of the first guide groove 710 near the welding machine 2 is an inclined straight line. This is used to drive the first guide rod 711 to move upward when the shaping clamp 9 moves to the welding position, compressing the gas between the first push rod 76 and the alloy faucet to form a strong... The first guide groove 710 is connected to a second guide groove 712 on the side near the welding machine 2. Point a is provided on the side of the second guide groove 712 near the welding machine 2, and point b is provided on the side of the second guide groove 712 away from the welding machine 2. The horizontal height of point a of the second guide groove 712 is higher than the horizontal height of point b of the second guide groove 712. This is used to drive the first guide rod 711 downward to reset after welding, so that the air pressure returns to normal. A sealing strip 715 is fixedly connected to the inner edge of the shaping clamp 9. This is used to seal the edge when the shaping clamp 9 clamps the alloy faucet to prevent gas leakage.

[0023] The rotating mechanism 8 includes a top plate 81, a fixed plate 82, a sliding plate 83, a second push plate 84, a rotating rod 85, a second elastic telescopic rod 86, a hole 87, a third guide groove 88, a second guide rod 89, a fifth guide groove 810, and a fourth guide groove 811. The top plate 81 is fixedly connected to one end of the shaping clamping plate 9 and moves synchronously with the shaping clamping plate 9. A fixed plate 82, which is fixedly connected to the base 1, is provided on the side of the top plate 81 away from the welding machine 2. A sliding plate 83, which is slidably connected to the base 1, is provided on the side of the fixed plate 82 away from the welding machine 2. A second push plate 84, which is fixedly connected to the top plate 81, is provided at the middle position between the sliding plate 83 and the fixed plate 82. The sliding plate 83 is used to push the sliding plate 83 to move laterally when the shaping clamp 9 is reset. The inner side of the fixed plate 82 is rotatably connected to the rotating rod 85, which is fixedly connected to the silicone rubber cleaning block 11. The upper end of the sliding plate 83 is provided with a hole 87 for nesting the rotating rod 85. The hole 87 and the rotating rod 85 are clearance-fitted so that the rotating rod 85 can rotate freely in the hole 87. The outer side of the rotating rod 85 is provided with a third guide groove 88. The appearance structure of the third guide groove 88 is spiral. The inner side of the third guide groove 88 is provided with a second guide rod 89 fixedly connected to the sliding plate 83, which is used to drive the rotating rod 85 to rotate when the sliding plate 83 moves laterally.

[0024] The other end of the second guide groove 712 is connected to the fifth guide groove 810. The fifth guide groove 810 is composed of two inclined straight grooves connected together, and the intersection of the two inclined straight grooves of the fifth guide groove 810 faces upward. It is used to drive the first guide rod 711 to move upward and then downward when the shaping clamp 9 is reset. The other end of the fifth guide groove 810 is connected to the fourth guide groove 811 connected to the first guide groove 710. Point c is set on the side of the fourth guide groove 811 away from the welding machine 2, and point d is set on the side of the fourth guide groove 811 closer to the welding machine 2. The horizontal height of point c of the fourth guide groove 811 is lower than the horizontal height of point d of the second guide groove 712, forming a complete guide trajectory.

[0025] A second elastic telescopic rod 86 is fixedly connected at the lower position between the sliding plate 83 and the fixed plate 82. It is used to push the sliding plate 83 to reset when the shaping clamp 9 is reset, so that the silicone rubber cleaning block 11 keeps in contact with the inner wall of the shaping clamp 9.

[0026] When welding alloy faucets and water pipes is required, first place the alloy faucet inside the shaping clamp 9, start the third electric push rod 10 to move the shaping clamp 9 towards the center to clamp the alloy faucet, start the electric clamping plate 5 to clamp the water pipe, start the first electric push rod 3 to move the first slide plate 4 and the electric clamping plate 5 towards the welding machine 2 to the predetermined position, start the second electric push rod 6 to move the first elastic telescopic rod 714, the second slide plate 71, the shaping clamp 9 and the alloy faucet towards the welding machine 2 to the predetermined position.

[0027] During the process of the shaping clamp 9 moving towards the welding machine 2 to the predetermined position, the air guide pipe 73, the first push rod 76, the spring 77, the first push plate 78 and the first guide rod 711 move synchronously towards the welding machine 2. Since the first guide groove 710 is horizontal and straight on the side away from the welding machine 2 and inclined and straight on the side close to the welding machine 2, when the first guide rod 711 moves to the top of the inclined section of the first guide groove 710, the alloy faucet also moves to the predetermined position. At this time, the sealing strip 715 seals the edge of the shaping clamp 9, and the first guide rod 711 moves upward along the inclined section, driving the first push plate 78, the spring 77 and the first push rod 76 to move upward.

[0028] At this time, the gas between the first push rod 76 and the alloy faucet is compressed. Although the gas cannot be compressed further, the pressure of the spring 77 on the first push rod 76 causes the air pressure between the first push rod 76 and the alloy faucet to continuously increase. This strong air pressure is transmitted to various areas inside the shaping clamp 9 through the air guide hole 74 and the air guide groove 75, forming a continuous and uniform air pressure. This air pressure directly acts on the impurities between the alloy faucet shell and the groove of the shaping clamp 9, firmly pressing the impurities remaining at the bottom of the groove. This makes it difficult for the impurities to roll or move even if they are affected by vibration or thermal expansion and contraction during the welding process, ensuring the stability of the initial welding position and improving the welding qualification rate.

[0029] Since the generation of this strong air pressure depends on the necessary movement of the shaping clamp 9 to the welding position, it avoids forgetting to start the strong pressure process due to negligence in the operation process, and ensures that impurities can be automatically suppressed in each welding.

[0030] After welding is completed, the second electric push rod 6 is started to continue moving towards the side of the welding machine 2. At this time, since the alloy faucet has been welded to the water pipe, the alloy faucet cannot continue to move, but the first elastic telescopic rod 714 can continue to compress, applying a continuous clamping force to the shaping clamp 9 and the alloy faucet. This clamping force effectively compensates for the amount of metal shrinkage generated during the welding cooling process, avoiding gaps, cracks or leaks in the weld due to shrinkage, and improving the welding quality.

[0031] Since the upper end of the air duct 73 is a flexible tube and the lower end is a rigid tube, and the lower end of the air duct 73 is fixedly connected to the fixed end of the first elastic telescopic rod 714, when the telescopic end of the first elastic telescopic rod 714 continues to move, it can still drive the first push plate 78 and the first guide rod 711 to continue to move, so that the first guide rod 711 moves to point a of the second guide groove 712. Since the horizontal height of point a of the second guide groove 712 is higher than point b, the first guide rod 711 moves downward to reset after reaching point a, so that the air pressure between the first push rod 76 and the alloy faucet returns to normal. At this time, the clamping force is appropriately reduced, leaving deformation space for the workpiece when it cools and shrinks, preventing the weld from cracking due to rigid clamping, and further ensuring the welding quality.

[0032] After cooling, the third electric push rod 10 is activated to move the shaping clamping plate 9 to both sides, removing the welded workpiece. During the repositioning of the shaping clamping plate 9 to both sides, the silicone rubber cleaning block 11 is inserted into the inner side of the shaping clamping plate 9. The shaping clamping plate 9 drives the top plate 81 and the second push plate 84 to move synchronously. The second push plate 84 pushes the sliding plate 83 and the second guide rod 89 to move laterally. Since the third guide groove 88 is spiral, the second guide rod 89 drives the rotating rod 85 to rotate during the lateral movement. The rotating rod 85 drives the silicone rubber cleaning block 11 to rotate and scrape the inner wall of the shaping clamping plate 9, reducing the impact of residual impurities on the subsequent workpiece clamping accuracy and ensuring the cleanliness of the clamping surface.

[0033] The second electric push rod 6 is activated, which drives the first elastic telescopic rod 714, the second sliding plate 71, and the shaping clamp 9 to move away from the welding machine 2. Since the horizontal height of point a of the second guide groove 712 is higher than that of point b, the first guide rod 711 moves to point b of the second guide groove 712. When the first guide rod 711 enters the fifth guide groove 810, since the fifth guide groove 810 is composed of two inclined straight grooves connected together and the intersection point faces upward, the first guide rod 711 first moves along the upward inclined groove, which drives the first push rod 76 to move upward, pushing the gas inside the air pipe 73 to the outside, so that the gas is blown out through the air hole 74 and the air groove 75, further blowing away the cleaned impurities and reducing the impurities remaining inside the shaping clamp 9.

[0034] Subsequently, the first guide rod 711 moves to the intersection of the fifth guide groove 810 and moves along the downward inclined groove, driving the first push rod 76 to move downward, pulling the gas inside the air guide tube 73 inward to form a negative pressure. This negative pressure pulls the silicone rubber cleaning block 11 to fit tightly against the inner wall of the shaping clamp 9, so that the silicone rubber cleaning block 11 maintains close contact with the inner wall when the shaping clamp 9 is idle, preventing impurities from entering the inner side of the shaping clamp 9 and further reducing impurity residue.

[0035] Because gas enters the vent 74 during the welding stage to form a strong pressure, and gas is discharged during the resetting stage to form a purging effect, the back-and-forth movement of the gas makes it difficult for impurities to clog the vent 74, effectively reducing maintenance costs.

[0036] For irregularly shaped workpieces like alloy faucets, the inner wall of its shaping clamp (9) inevitably has a large number of grooves, corners and gaps that are compatible with alloy faucets. This makes it much more difficult to clean impurities than for flat or regular workpieces. In this invention, the impurities are first pressed down by strong air pressure to prevent them from being repeatedly squeezed and embedded deep in the grooves of the clamp during welding vibration and thermal expansion and contraction. This prevents them from turning from surface dust into embedded hard particles. This anti-embedding mechanism allows the impurities to be effectively blown away during subsequent positive air pressure purging, rather than being stuck in the gaps. Subsequently, the silicone rubber cleaning block 11 only needs to rotate in contact with the unembedding surface impurities, avoiding violent scraping with the hard impurities that have been pressed deep into the grooves. This reduces the wear rate of the silicone rubber cleaning block and allows it to conform to the original contour of the inner wall of the clamp, maintaining effective cleaning accuracy and extending the service life of the silicone rubber cleaning block 11.

[0037] When the first guide rod 711 moves to the fourth guide groove 811, since the horizontal height of point c in the fourth guide groove 811 is lower than that of point d, the first guide rod 711 moves along the fourth guide groove 811 back to the initial position, and one welding process ends.
