Description

Technical Field

[0001] This invention relates to the field of brazing equipment technology, specifically to a welding equipment for processing oil pipes for automotive turbochargers. Background Technology

[0002] In the processing of automotive turbocharger oil pipes, welding equipment is often used to connect different pipe joints. Common welding methods include electric welding, gas welding, laser welding, brazing, and crimping. Brazing involves heating the workpiece and a low-melting-point filler metal to melt, using the liquid filler metal to fill the gaps between the parts and form a strong connection. In addition, the temperature during brazing is lower than the melting temperature of the base material, which can avoid material deformation or cracking caused by high-temperature welding. This better ensures the dimensional accuracy and original performance of the oil pipe components. Compared with other welding methods, the use of brazing for automotive turbocharger oil pipes not only ensures a tight connection between the oil pipes, but also avoids the oil pipes from generating large thermal stress due to overheating, thereby avoiding the deformation of the oil pipe components.

[0003] In the process of flame brazing, the operator needs to hold the welding gun in one hand to heat it and the filler metal rod in the other hand to melt the filler metal and fill the gap. It uses the flame of the combustion of combustible gas and oxygen or compressed air as the heat source for welding. When the base material does not melt, the filler metal melts and wets and fills the gap at the joint of the two base materials to form a brazing seam.

[0004] Existing brazing equipment struggles to find a stable gripping point when clamping oil pipes due to the smooth surface of the pipes, increasing the difficulty of clamping. To ensure the oil pipes remain stable during brazing without wobbling or displacement, sufficient clamping force is required. This necessitates operators spending considerable time repeatedly trying and adjusting the clamping force to avoid damage to the pipes caused by excessive clamping force, which significantly impacts work efficiency and production progress.

[0005] In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes a welding equipment for processing automotive turbocharger oil pipes, which solves the above-mentioned technical problems. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes a welding device for processing automotive turbocharger oil pipes. This invention utilizes the cooperation of a clamping plate and clamping blocks. During the clamping process, an electric push rod pushes the clamping blocks through the clamping plate to hold the oil pipe. The clamping blocks in contact with the oil pipe are blocked by the pipe, causing the connecting spring to press against the clamping plate. This compressed connecting spring applies pressure to a pressure sensor, enabling the pressure sensor to detect the clamping force applied to the oil pipe. This allows the operator to accurately adjust the clamping force based on the pressure value transmitted from the pressure sensor to the detection equipment. While ensuring the stability of the oil pipe, it avoids damage to the pipe body due to excessive clamping force, eliminating the need for repeated attempts and saving working time, thus improving work efficiency and production progress.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A welding device for processing automotive turbocharger oil pipes, comprising a body, a welding torch connected to the body, and a mounting frame installed on the upper end of the body; a rotating ring rotatably connected to one side of the mounting frame; an arc-shaped plate provided on the side of the rotating ring near the center of the body; two arc-shaped plates are provided; one end of each arc-shaped plate is rotatably connected to the rotating ring, and the other end is connected by bolts; two opposing clamping plates are provided between the two arc-shaped plates; electric push rods are fixedly connected to the ends of the two clamping plates that are far apart from each other; the ends of the two electric push rods that are far from the clamping plates are respectively fixedly connected to the two arc-shaped plates; two sets of mounting frames are provided; the two sets of mounting frames are distributed opposite each other; a gear ring is fixedly connected to the side of the rotating ring away from the arc-shaped plate; a transmission rod is rotatably connected to the upper end of the body; a transmission gear is fixedly connected to the surface of the transmission rod; the transmission gear meshes with the gear ring; a drive motor is fixedly installed on one side of the body; the drive motor is used to drive the transmission gear to rotate.

[0008] Preferably, the clamping plate has a connecting hole on the side away from the electric push rod; a connecting rod is slidably connected in the connecting hole; a clamping block is fixedly connected to the end of the connecting rod away from the clamping plate; a pressure sensor is embedded in the side of the clamping plate near the clamping block; the clamping block and the pressure sensor are fixedly connected by a connecting spring.

[0009] Preferably, electromagnetic plates are embedded at both ends of the clamping plate.

[0010] Preferably, an elastic block is fixedly connected to the end of the clamping block away from the clamping plate; the elastic block is triangular; and the rubber block is made of fluororubber material.

[0011] Preferably, the two sets of mounting brackets are connected by a screw drive; the threads at both ends of the screw are opposite; the screw is connected to the drive motor through a transmission unit; the drive motor drives the screw to rotate through the transmission unit.

[0012] Preferably, the transmission unit includes:

[0013] A straight rod; a rectangular slot is provided at the output end of the drive motor; the straight rod is slidably and sealed within the rectangular slot; the straight rod is connected to the bottom of the rectangular slot by a support spring; an electromagnetic plate is embedded in the bottom of the rectangular slot; a slot that mates with the rectangular slot is provided at the end of the screw near the drive motor.

[0014] The drive motor's output end is connected to a drive rod via a drive belt; the output end of the drive motor has a groove communicating with a rectangular slot on its surface; a positioning rod is slidably and sealed within the groove; the positioning rod is connected to the groove wall via a fixed spring; the drive belt surface has a circular groove that mates with the positioning rod; the drive rod engages with the circular groove on the drive belt surface via a protrusion fixed to its surface.

[0015] Preferably, each group of mounting brackets has two brackets; the gear ring is fixedly connected to the mounting bracket near the center of the machine body; a lead screw is provided between the two mounting brackets; one end of the lead screw is fixedly connected to the mounting bracket with the gear ring, and the other end is helically connected to the mounting bracket of the group without the gear ring installed.

[0016] Preferably, both the screw and the lead screw are fitted with a bellows; the bellows are made of silicone rubber.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. In this invention, during the clamping process of the clamping plate pushing the clamping block to hold the oil pipe, the clamping block in contact with the oil pipe is blocked by the oil pipe and squeezes the connecting spring close to the clamping plate. This squeezed connecting spring applies pressure to the pressure sensor, which can detect the clamping force applied by the clamping block to the oil pipe. This allows the operator to accurately adjust the clamping force of the oil pipe based on the pressure value transmitted from the pressure sensor to the detection equipment. While ensuring the stability of the oil pipe, it avoids damage to the oil pipe body due to excessive clamping force. It eliminates the need for repeated attempts, thereby saving working time and improving work efficiency and production progress.

[0019] 2. This invention, by setting a screw and two sets of mounting brackets for helical transmission, allows the user to drive the screw to rotate via a drive motor. During this rotation, the screw drives the two sets of mounting brackets to move away from each other, causing the mounting brackets to move the clamping blocks away from each other. This allows the clamping blocks to hold the center of the long oil pipe, thereby reducing the lever arm and torque of the portion of the oil pipe away from the welding end. This improves the clamping stability of the oil pipe, preventing it from shaking during brazing due to slight vibrations, changes in welding thermal stress, or other external forces. This enhances brazing stability and ensures brazing quality. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 5As shown, the welding equipment for processing automotive turbocharger oil pipes according to the present invention includes a body 1, a welding torch 11 connected to the body 1 is disposed on the upper part of the body 1, and a mounting frame 2 is mounted on the upper end of the body 1; a rotating ring 21 is rotatably connected to one side of the mounting frame 2; an arc-shaped plate 22 is disposed on the side of the rotating ring 21 near the center of the body 1; two arc-shaped plates 22 are provided; one end of the two arc-shaped plates 22 is rotatably connected to the rotating ring 21, and the other end is connected by bolts; two opposing clamping plates 221 are disposed between the two arc-shaped plates 22; the two clamping plates 221 are... An electric push rod 222 is fixedly connected to each other at one end; the ends of the two electric push rods 222 that are away from the clamping plate 221 are respectively fixedly connected to two arc-shaped plates 22; two sets of mounting frames 2 are provided; the two sets of mounting frames 2 are distributed opposite each other; a gear ring 23 is fixedly connected to the side of the rotating ring 21 away from the arc-shaped plate 22; a transmission rod 12 is rotatably connected to the upper end of the machine body 1; a transmission gear 13 is fixedly connected to the surface of the transmission rod 12; the transmission gear 13 meshes with the gear ring 23; a drive motor 14 is fixedly installed on one side of the machine body 1; the drive motor 14 is used to drive the transmission gear 13 to rotate.

[0029] In one embodiment of the present invention, a connecting hole 223 is provided on the side of the clamping plate 221 away from the electric push rod 222; a connecting rod 224 is slidably connected in the connecting hole 223; a clamping block 225 is fixedly connected to the end of the connecting rod 224 away from the clamping plate 221; a pressure sensor 24 is embedded on the side of the clamping plate 221 near the clamping block 225; the clamping block 225 and the pressure sensor 24 are fixedly connected by a connecting spring 241.

[0030] In one embodiment of the present invention, electromagnetic plates 25 are embedded at both ends of the clamping plate 221.

[0031] In one embodiment of the present invention, an elastic block 26 is fixedly connected to one end of the clamping block 225 away from the clamping plate 221; the elastic block 26 is triangular; the rubber block is made of fluororubber material.

[0032] During operation, existing brazing equipment struggles to find a stable gripping point when clamping oil pipes due to the smooth surface of the pipes, increasing the difficulty of clamping. To ensure the oil pipes remain stable during brazing without shaking or displacement, sufficient clamping force is required. This necessitates operators spending considerable time repeatedly trying and adjusting the clamping force to avoid damage to the oil pipes caused by excessive clamping force, which significantly impacts work efficiency and production progress.

[0033] In this invention, the cooperation between the clamping plate 221 and the clamping block 225 allows the electric push rod 222 to push the clamping block 225 to clamp the oil pipe through the clamping plate 221. During this process, the clamping block 225, which is in contact with the oil pipe, is blocked by the oil pipe and squeezes the connecting spring 241 close to the clamping plate 221. This squeezes the connecting spring 241 and applies pressure to the pressure sensor 24, enabling the pressure sensor 24 to detect the clamping force applied by the clamping block 225 to the oil pipe. This allows the operator to accurately adjust the clamping force of the oil pipe based on the pressure value transmitted from the pressure sensor 24 to the detection equipment. This ensures the stability of the oil pipe while avoiding damage to the oil pipe body due to excessive clamping force. It also eliminates the need for repeated attempts, thus saving working time and improving work efficiency and production progress.

[0034] In the initial state, the user closes the two arc-shaped plates 22, causing them to rotate towards each other along the hinge point until the ends of the two arc-shaped plates 22 furthest from the hinge point contact each other. Then, bolts are used to connect the two hinged arc-shaped plates 22. Before welding the turbocharger oil pipe, the user first energizes the electromagnetic plate 25, causing it to attract the clamping block 225, compress the connecting spring 241, and bring it closer to the clamping plate 221. This increases the space between the two arc-shaped plates 22, ensuring that the clamping block 225 does not obstruct the oil pipe as it passes through the arc-shaped plates 22. Subsequently, the user places the part to be welded... Two oil pipes are respectively inserted into the rotating rings 21 on the two sets of mounting brackets 2. That is, the welding part of the oil pipe is inserted into the rotating ring 21 from the end of the rotating ring 21 near the gear ring 23, and passes between the two arc plates 22 of the same mounting bracket 2, so that the oil pipe passes between the two clamps 225, and the welding part of the oil pipe is in contact at the center of the machine body 1. At this time, the control electromagnetic plate 25 is de-energized, so that the electromagnetic plate 25 no longer generates magnetic attraction force on the clamps 225. Under the push of the restoring force of the connecting spring 241, the clamps 225 move away from the clamps 221 until the connecting spring 241 returns to its original position. At this time, the control electric push rod is activated. 222 extends, allowing the electric push rod 222 to push the clamping plate 221, causing the clamping block 225 to approach the oil pipe until the clamping block 225 contacts the oil pipe. At this point, the electric push rod 222 continues to push the clamping plate 221 closer to the oil pipe. Due to the obstruction of the oil pipe, the clamping block 225, blocked by the oil pipe, continuously moves closer to the clamping plate 221, causing the connecting spring 241 between the clamping plate 221 and the clamping block 225 to be compressed again. This compression of the connecting spring 241 generates a compressive force on the pressure sensor 24, causing the pressure sensor 24 to generate an electrical signal under the pressure of the connecting spring 241. The interaction is mutual. Therefore, the pressure sensor 24 senses the squeezing force of the connecting spring 241, which is the pushing force exerted by the connecting spring 241 on the clamping block 225, and also the clamping force exerted by the connecting spring 241 on the clamping block 225 on the oil pipe. Thus, the pressure sensed by the pressure sensor 24 is the clamping force exerted by the clamping block 225 on the oil pipe. After sensing the squeezing force exerted by the connecting spring 241, the pressure sensor 24 transmits it to the detection computer connected to the welding equipment via an electrical signal. This allows the user to observe the pressure value transmitted by the pressure sensor 24 and thus accurately adjust the clamping force of the oil pipe.By setting the connecting rod 224, the clamping block 225 can be slidably connected to the clamping plate 221 through the connecting rod 224. During the clamping process of the clamping block 225 clamping the oil pipe, as the electric push rod 222 pushes the clamping plate 221 closer to the clamping block 225, the clamping block 225 can smoothly compress the connecting spring 241 and move closer to the pressure sensor 24 under the limit of the connecting rod 224. This prevents the clamping block 225 from shifting and avoids the connecting spring 241 between the clamping block 225 and the clamping plate 221 from tilting due to the shift of the clamping block 225. This ensures that the connecting spring 241 can be vertically compressed by the clamping block 225. To ensure that the compressive force applied by the clamping block 225 to the connecting spring 241 is perpendicular to the pressure sensor 24, the pressure sensor 24 can accurately detect the pressure applied by the connecting spring 241 to the clamping block 225, thereby improving the accuracy of the clamping force detection of the oil pipe and effectively enhancing the practicality of the invention; by setting a triangular elastic block 26 fixedly connected to the end of the clamping block 225 away from the clamping plate 221, the triangular elastic block 26 can increase the friction between the clamping block 225 and the outer wall of the oil pipe, thereby improving the clamping stability of the clamping block 225 on the oil pipe; thus effectively enhancing the practicality of the invention;

[0035] After clamping the two oil pipes, the welding joints of the two oil pipes are in contact with each other. The user then holds the welding torch 11 in one hand and the brazing filler metal in the other, aligning one end of the filler metal with the gap between the two oil pipes. The welding torch 11 is then directed towards the contact end between the filler metal and the oil pipe, allowing the flame from the welding torch 11 to melt the filler metal. The molten filler metal fills the gap between the two oil pipes, thus completing the welding of the two oil pipes. During the welding process, the operator can control the drive motor 14 to drive the transmission rod 12 to rotate, and the transmission rod 12 drives the transmission gear 13 fixed to the surface to rotate synchronously. This allows the transmission gear 13 to drive the meshing gear ring 23 to rotate synchronously, and the gear ring 23 to drive the rotating ring 21 fixed to it to rotate synchronously during the rotation. The rotating ring 21 rotates synchronously through the arc plate 22, clamp 221, clamp block 225, and the oil pipe held by the clamp block 225, allowing the operator to perform brazing on the circumference of the rotating oil pipe. This method ensures that all parts of the pipeline are heated evenly, resulting in more stable welding quality. Moreover, the welding position is relatively fixed during the rotation process, which not only reduces the welding difficulty for the operator but also allows the operator to concentrate on controlling the welding parameters, improving welding efficiency and welding quality.

[0036] In one embodiment of the present invention, the two sets of mounting brackets 2 are connected by a screw 15 for helical transmission; the threads at both ends of the screw 15 are arranged in opposite directions; the screw 15 is connected to the drive motor 14 through a transmission unit; the drive motor 14 drives the screw 15 to rotate through the transmission unit.

[0037] In one embodiment of the present invention, the transmission unit includes:

[0038] A straight rod 141; a rectangular slot 142 is provided at the output end of the drive motor 14; the straight rod 141 is slidably and sealed within the rectangular slot 142; the straight rod 141 and the bottom of the rectangular slot 142 are connected by a support spring 143; an electromagnetic plate 144 is embedded in the bottom of the rectangular slot 142; a slot 151 that mates with the rectangular slot 142 is provided at the end of the screw 15 near the drive motor 14.

[0039] The drive motor 14 is connected to the drive rod 12 via a drive belt 16. The output end of the drive motor 14 is provided with a groove 145 that communicates with a rectangular groove 142. A positioning rod 146 is slidably and sealed within the groove 145. The positioning rod 146 is connected to the groove wall of the groove 145 by a fixing spring 147. The drive belt 16 is provided with a circular groove 161 that mates with the positioning rod 146. The drive rod 12 engages with the circular groove 161 on the surface of the drive belt 16 via a protrusion 121 fixed to its surface.

[0040] In one embodiment of the present invention, each group of mounting brackets 2 is provided with two brackets; the gear ring 23 is fixedly connected to the mounting bracket 2 near the center of the body 1; a lead screw 17 is provided between the two mounting brackets 2; one end of the lead screw 17 is fixedly connected to the mounting bracket 2 with the gear ring 23, and the other end is helically connected to the mounting bracket 2 of the group without the gear ring 23 installed.

[0041] In one embodiment of the present invention, both the screw 15 and the lead screw 17 are fitted with a bellows 18; the bellows 18 is made of silicone rubber.

[0042] During operation, the length of the turbocharger oil pipe varies depending on the car model. When brazing longer oil pipes, the part of the oil pipe clamped by the clamping block 225 is close to the welding end of the oil pipe. For long oil pipes, when the clamping block 225 clamps the oil pipe close to the welding end, the part far from the welding end forms a long lever arm. During the brazing process, if affected by external forces such as slight vibration or changes in welding thermal stress, the long lever arm will generate a large torque. This large torque will make the oil pipe easily rotate or wobble around the clamping point of the clamping block 225, making it difficult for the entire oil pipe to maintain a stable position, causing unstable clamping and affecting the brazing quality.

[0043] To address this, the present invention provides a screw 15 connected to two sets of mounting brackets 2 via a helical transmission. This allows the user to drive the screw 15 to rotate via the drive motor 14. During this process, the screw 15 drives the two sets of mounting brackets 2 to move away from each other, causing the mounting brackets 2 to move the clamping blocks 225 away from each other. This allows the clamping blocks 225 to clamp the center of the long oil pipe, thereby reducing the lever arm and torque of the portion of the oil pipe away from the welding end. This improves the clamping stability of the clamping blocks 225 on the oil pipe, preventing the oil pipe from shaking due to slight vibrations, changes in welding thermal stress, or other external forces during brazing. This enhances the stability of the brazing process and ensures the quality of the brazing.

[0044] Initially, the electromagnetic plate 144 is de-energized. The straight rod 141 within the rectangular slot 142, pushed by the support spring 143, extends out of the rectangular slot 142 and inserts into the slot 151. At this time, the drive motor 14 and the screw 15 are connected. When the user needs to control the distance between the two sets of mounting brackets 2, the user only needs to control the drive motor 14, causing it to drive the screw 15 to rotate via the straight rod 141. Because the threads at both ends of the screw 15 are opposite, during rotation, the screw 15 can drive the two sets of mounting brackets 2 at both ends to move away from each other, continuously increasing the distance between the two mounting brackets 2. This reduces the lever arm of the portion of the oil pipe away from the welding end, thus increasing the torque. This reduces friction, thereby improving the clamping stability of the clamping block 225 on the oil pipe. Since the output shaft of the drive motor 14 and the transmission rod 12 are connected by a belt drive 16, sliding friction occurs between the drive motor 14 and the belt 16 when the output shaft of the drive motor 14 rotates. Therefore, by making the belt 16 of PTFE material, it has a smooth surface, greatly reducing the friction between the output end of the drive motor 14 and the belt 16. This prevents the drive motor 14 from driving the belt 16 to rotate through static friction. When the drive motor 14 needs to control the rotation of the transmission rod 12, the user only needs to energize the electromagnetic plate 144, causing the electromagnetic plate 144 to generate a magnetic attraction force on the straight rod 141. Since the rectangular groove 142 is filled with hydraulic oil, when the straight rod 141 enters the rectangular groove 142, the straight rod 141 will squeeze the hydraulic oil in the rectangular groove 142. This squeezed hydraulic oil will flow into the groove 145, causing the positioning rod 146 in the circular groove 161 to be pushed by the hydraulic oil, thus pushing the fixing spring 147 out of the groove 145. This allows the positioning rod 146, extending out of the groove 145, to insert into the circular groove 161 on the surface of the transmission belt 16. This allows the output end of the drive motor 14 to push the groove wall of the circular groove 161 through the positioning rod 146, thereby driving the transmission belt 16 to rotate. Because the transmission rod 12 engages with the circular groove 161 on the surface of the transmission belt 16 through the protrusion 121 fixed to its surface, the drive motor... 14 can drive the transmission rod 12 to rotate via the transmission belt 16; the transmission rod 12 drives the gear ring 23 to rotate via the transmission gear 13 fixed to the surface, and the rotating ring 21 drives the oil pipe to rotate via the arc plate 22 and the clamping block 225 for brazing; by setting the number of mounting brackets 2 in each group to two, the number of mounting brackets 2 is increased, thereby increasing the balance support points for the oil pipe. The user can rotate the screw 17 to drive the mounting bracket 2 without the gear ring 23 to move away from the mounting bracket 2 with the gear ring 23 fixed to it, thereby adjusting the distance between the two mounting brackets 2, and thus adjusting the position of the two support points of the oil pipe, so that oil pipes of different lengths can be stably clamped and supported.The bellows 18 is designed to protect the screw 15 and lead screw 17. During brazing, the bellows 18 prevents weld spatter from landing on the surfaces of the screw 15 and lead screw 17, thereby improving the helical transmission effect of the screw 15 and lead screw 17. This effectively enhances the practical application effect of the invention. Furthermore, by making the bellows 18 from silicone rubber, it possesses good heat resistance and flame retardancy, thus extending its service life.
