Description

Technical Field

[0001] The invention relates to the technical field of brazing equipment, in particular to a welding device for processing an automobile supercharger oil pipe. Background Art

[0002] In the processing of automobile supercharger oil pipes, welding equipment is often used to connect different pipe joints, and the common welding processing methods mainly include electric welding, gas welding, laser welding, brazing and crimping; among them, brazing heats the weldment and the brazing material with a lower melting point until they are melted, and uses the liquid brazing material to fill the gap between the parts to form a firm connection; in addition, the temperature during brazing is lower than the melting temperature of the parent material, which can avoid material deformation or cracks caused by high-temperature welding, and can better ensure the dimensional accuracy and original performance of the oil pipe components. Compared with other welding methods, the automobile supercharger oil pipe is welded by brazing, which can not only ensure the tight connection between the oil pipes, but also avoid the oil pipes from generating large thermal stress due to overheating, thereby avoiding the deformation of the oil pipe components;

[0003] During the flame brazing process, the operator needs to hold the welding gun in one hand to heat it and hold the brazing material rod in the other hand to melt the brazing material and fill the gap. The flame of a mixture of combustible gas and oxygen or compressed air is used as a heat source for welding. When the parent material is not melted, the brazing material is melted and wetted and fills the gap at the connection of the two parent materials to form a brazing seam.

[0004] When existing brazing equipment clamps the oil pipe, it is difficult to find a stable point of force during the clamping process due to the smooth body of the oil pipe, which increases the difficulty of clamping. To ensure that the oil pipe remains stable during the brazing process without shaking or displacement, sufficient clamping force is required. This requires operators to spend a lot of time repeatedly trying and adjusting the clamping force of the oil pipe when using the brazing equipment to clamp the oil pipe, thereby avoiding damage to the oil pipe body due to excessive clamping force, which greatly affects work efficiency and production progress.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes a welding device for processing an automobile supercharger oil pipe, which solves the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] As an embodiment of the present invention, a connecting hole 223 is provided on a side of the splint 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 one end of the connecting rod 224 away from the splint 221; a pressure sensor 24 is embedded on a side of the splint 221 close to the clamping block 225; the clamping block 225 and the pressure sensor 24 are fixedly connected via a connecting spring 241.

[0030] As an implementation mode of the present invention, electromagnetic sheets 25 are embedded at both ends of the clamping plate 221 .

[0031] As an embodiment of the present invention, the end of the clamping block 225 away from the clamping plate 221 is fixedly connected with an elastic block 26; the elastic block 26 is configured as a triangle; the rubber block is made of fluororubber material;

[0032] During operation, when the existing brazing equipment clamps the oil pipe, it is difficult to find a stable point of force during the clamping process due to the smooth body of the oil pipe, which increases the difficulty of clamping. To ensure that the oil pipe remains stable during the brazing process without shaking or displacement, sufficient clamping force is required. This requires operators to spend a lot of time repeatedly trying and adjusting the clamping force of the oil pipe when using the brazing equipment to clamp the oil pipe, thereby avoiding damage to the oil pipe body due to excessive clamping force, which greatly affects work efficiency and production progress.

[0033] In this regard, the present invention cooperates with the clamping plate 221 and the clamping block 225, so that in the process of the electric push rod 222 pushing the clamping block 225 to clamp the oil pipe through the clamping plate 221, the clamping block 225 in contact with the oil pipe is blocked by the oil pipe and squeezes the connecting spring 241 close to the clamping plate 221, so that the squeezed connecting spring 241 applies pressure to the pressure sensor 24, so that the pressure sensor 24 can detect the clamping force applied by the clamping block 225 to the oil pipe, so that the operator can accurately adjust the clamping force of the oil pipe according to the pressure value transmitted to the detection device by the pressure sensor 24, while ensuring the stability of the oil pipe, avoiding damage to the oil pipe body due to excessive clamping force, without spending a lot of time on repeated attempts, thereby saving working time and improving work efficiency and production progress;

[0034] In the initial state, the user closes the two arc plates 22, so that the two arc plates 22 rotate along the hinge point in the direction of approaching each other until the ends of the two arc plates 22 away from the hinge point touch each other, and then uses bolts to connect the two hinged arc plates 22. Before welding the oil pipe of the automobile supercharger, the user first controls the electromagnetic sheet 25 to energize, so that the electromagnetic sheet 25 can absorb the clamping block 225 to squeeze the connecting spring 241 and approach the clamping plate 221, so that the space between the two arc plates 22 is increased, so that when the oil pipe passes through the arc plate 22, the clamping block 225 will not block the oil pipe; then the user places the required welding The two oil pipes are respectively placed in the rotating rings 21 on the two sets of mounting frames 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 close to the gear ring 23, and passes through the two arc plates 22 of the same mounting frame 2, so that the oil pipe passes through the two clamping blocks 225, so that the welding part of the oil pipe is in contact with the center of the body 1. At this time, the electromagnetic sheet 25 is controlled to be powered off, so that the electromagnetic sheet 25 no longer generates magnetic adsorption force on the clamping block 225, so that the clamping block 225 moves away from the clamping plate 221 under the push of the restoring force of the connecting spring 241 until the connecting spring 241 is restored, and the electric push rod is controlled at this time. 222 stretches, so that the electric push rod 222 can push the clamping plate 221 to drive the clamping block 225 close to the oil pipe until the clamping block 225 contacts the oil pipe. At this time, the electric push rod 222 continues to push the clamping plate 221 close to the oil pipe. Since the clamping block 225 is blocked by the oil pipe, the clamping block 225 blocked by the oil pipe continues to approach the clamping plate 221, so that the connecting spring 241 between the clamping plate 221 and the clamping block 225 is squeezed and compressed again, so that the compressed connecting spring 241 generates a squeezing force on the pressure sensor 24, so that the pressure sensor 24 is subjected to the pressure of the connecting spring 241. The pressure sensor 24 generates an electrical signal. The use is mutual, so the pressure sensor 24 senses the squeezing force of the connecting spring 241, which is the pushing force applied by the connecting spring 241 to the clamping block 225, and is also the clamping force applied by the connecting spring 241 to the clamping block 225 to the oil pipe. Therefore, the pressure sensed by the pressure sensor 24 is the clamping force applied by the clamping block 225 to the oil pipe; and after the pressure sensor 24 senses the squeezing force applied by the connecting spring 241, it will be transmitted to the detection computer connected to the welding equipment through an electrical signal, so that the user can observe the pressure value transmitted by the pressure sensor 24, and then realize the accurate adjustment of the clamping force of the oil pipe;By providing the connecting rod 224, the clamping block 225 can be slidably connected to the clamping plate 221 through the connecting rod 224, so that when the clamping block 225 clamps the oil pipe, as the electric push rod 222 pushes the clamping plate 221 close to the clamping block 225, the clamping block 225 can smoothly squeeze the connecting spring 241 and approach the pressure sensor 24 under the limit of the connecting rod 224, so as to prevent the clamping block 225 from deviating, and avoid the connecting spring 241 between the clamping block 225 and the clamping plate 221 from tilting due to the deviation of the clamping block 225, thereby ensuring that the connecting spring 241 can be vertically squeezed by the clamping block 225. To ensure that the extrusion force applied by the clamp block 225 to the connecting spring 241 can be vertically directed toward the pressure sensor 24, so that the pressure sensor 24 can accurately detect the pressure applied by the connecting spring 241 to the clamp block 225, thereby improving the accuracy of the detection of the clamping force of the oil pipe, so that the practicality of the present invention is effectively improved; by setting the clamp block 225 away from the end of the clamp plate 221 and fixedly connected with the triangular elastic block 26, the triangular elastic block 26 can increase the friction between the clamp block 225 and the outer wall of the oil pipe, thereby improving the clamping stability of the clamp block 225 on the oil pipe; so that the practicality of the present invention is effectively improved;

[0035] After the two oil pipes are clamped, the welding parts of the two oil pipes are in contact with each other. Then the user holds the welding gun 11 with one hand and the brazing material with the other hand, so that one end of the brazing material is aimed at the gap where the two oil pipes are in contact. Then the welding gun 11 is held toward the contact end of the brazing material and the oil pipe, so that the flame sprayed from the welding gun 11 melts the brazing material, so that the hot-molten brazing material fills the gap between the two oil pipes, thereby realizing the welding of the two oil pipes. In the welding process, the operator can control the operation of the driving motor 14, so that the driving motor 14 drives the transmission rod 12 to rotate, and the transmission rod 12 drives the transmission gear 13 fixed on the surface to rotate synchronously. , so that the transmission gear 13 can drive the gear ring 23 meshing with it to rotate synchronously, so that the gear ring 23 can drive the swivel 21 fixed with it to rotate synchronously during the rotation process, so that the swivel 21 through the arc plate 22 clamping plate 221, the clamping block 225 and the oil pipe clamped by the clamping block 225 rotate synchronously, so that the operator can braze the circumference of the rotating oil pipe; this method can make all parts of the pipeline evenly heated, the welding quality is more stable, and in the rotation process, the welding position is relatively fixed, which not only reduces the welding difficulty of the operator, but also makes it easier for the operator to concentrate on controlling the welding parameters, thereby improving the welding efficiency and welding quality.

[0036] As an embodiment of the present invention, the two groups of mounting frames 2 are connected by a screw 15 through a spiral transmission; the threads at both ends of the screw 15 are arranged oppositely; the screw 15 is connected to the drive motor 14 through a transmission unit; and the drive motor 14 drives the screw 15 to rotate through the transmission unit.

[0037] As an implementation mode of the present invention, the transmission unit includes:

[0038] A straight rod 141; a rectangular groove 142 is provided at the output end of the drive motor 14; the straight rod 141 is slidably sealed and connected in the rectangular groove 142; the straight rod 141 is connected to the bottom of the rectangular groove 142 via a support spring 143; an electromagnetic plate 144 is inlaid at the bottom of the rectangular groove 142; a slot 151 matching the rectangular groove 142 is provided at one end of the screw rod 15 close to the drive motor 14;

[0039] Transmission belt 16, the output end of the driving motor 14 is connected to the transmission rod 12 through the transmission belt 16; the output end surface of the driving motor 14 is provided with a groove 145 connected to the rectangular groove 142; a positioning rod 146 is slidingly sealed in the groove 145; the positioning rod 146 is connected to the groove wall of the groove 145 through a fixing spring 147; a circular groove 161 is provided on the surface of the transmission belt 16 to match the positioning rod 146; the transmission rod 12 is meshed with the circular groove 161 on the surface of the transmission belt 16 through a protrusion 121 fixed on the surface.

[0040] As an embodiment of the present invention, the number of the mounting frames 2 in each group is set to two; the gear ring 23 is fixedly connected to the mounting frame 2 close to the center of the body 1; a screw rod 17 is arranged between the two mounting frames 2; one end of the screw rod 17 is fixedly connected to the mounting frame 2 fixedly connected with the gear ring 23, and the other end is spirally connected to the mounting frame 2 of the group without the gear ring 23 installed.

[0041] As an embodiment of the present invention, the surfaces of the screw rod 15 and the lead screw 17 are both sleeved with a bellows 18; the bellows 18 is made of silicone rubber material;

[0042] During operation, due to the different lengths of the oil pipes of the superchargers of different models of automobiles, when brazing a longer oil pipe, the portion of the oil pipe clamped by the clamp block 225 is close to the welding end of the oil pipe, and for a long oil pipe, when the clamp block 225 is clamped close to the welding end, a longer force arm is formed at the portion away from the welding end; during the brazing process, if it is affected by external forces such as slight vibration and welding thermal stress changes, the long force arm will generate a larger torque; this larger torque will make the oil pipe easily rotate or shake around the clamping point of the clamp block 225, making it difficult for the entire oil pipe to maintain a stable position, resulting in unstable clamping and affecting the brazing quality;

[0043] In this regard, the present invention sets a screw rod 15 and a spiral transmission connection between the two groups of mounting frames 2, so that the user can drive the screw rod 15 to rotate through the driving motor 14, and the screw rod 15 can drive the two groups of mounting frames 2 to move away from each other, so that the mounting frames 2 can drive the clamping blocks 225 to move away from each other, so that the clamping blocks 225 can clamp the center of the long oil pipe, thereby reducing the force arm of the part of the oil pipe away from the welding end, reducing the torque, and thus improving the clamping stability of the oil pipe by the clamping block 225, so as to avoid the oil pipe shaking due to external forces such as slight vibration and welding thermal stress changes during brazing, thereby improving the stability of brazing and ensuring the brazing quality;

[0044] In the initial state, the electromagnetic plate 144 is in a power-off state, and the straight rod 141 in the rectangular groove 142 is pushed out of the rectangular groove 142 by the support spring 143 and inserted into the slot 151. At this time, the driving motor 14 and the screw 15 are in a connected state; when the user needs to control the distance between the two groups of mounting frames 2, the user only needs to control the driving motor 14 to operate so that the driving motor 14 can drive the screw 15 to rotate through the straight rod 141; since the threads at both ends of the screw 15 are arranged in opposite directions; therefore, during the rotation of the screw 15, the screw 15 can drive the two groups of mounting frames 2 at both ends to move away from each other, so that the distance between the two mounting frames 2 is continuously increased, thereby reducing the force arm of the portion of the oil pipe away from the welding end, and the torque The friction between the output end of the drive motor 14 and the drive belt 16 is reduced, thereby improving the clamping stability of the clamp block 225 on the oil pipe; since the output shaft of the drive motor 14 and the transmission rod 12 are connected by the transmission belt 16, and when the output shaft of the drive motor 14 rotates, sliding friction will occur between the drive motor 14 and the transmission belt 16. Therefore, by setting the transmission belt 16 to be made of PTFE material, the transmission belt 16 has a smooth surface, which greatly reduces the friction between the output end of the drive motor 14 and the transmission belt 16; so that the drive motor 14 will not drive the transmission belt 16 to rotate through static friction; when the drive motor 14 is required to control the rotation of the transmission rod 12, the user only needs to control the electromagnetic plate 144 to be energized, so that the electromagnetic plate 144 generates a magnetic adsorption force on the straight rod 141 Since the rectangular groove 142 is filled with hydraulic oil, the straight rod 141 will squeeze the hydraulic oil in the rectangular groove 142 during the process of the straight rod 141 entering the rectangular groove 142, so that the squeezed hydraulic oil in the rectangular groove 142 will flow into the groove 145, so that the positioning rod 146 in the circular groove 161 is pushed by the hydraulic oil to squeeze the fixing spring 147 to extend out of the groove 145, so that the positioning rod 146 extending out of the groove 145 will be inserted into the circular groove 161 on the surface of the transmission belt 16, so that the output end of the drive motor 14 can push the groove wall of the circular groove 161 through the positioning rod 146, thereby driving the transmission belt 16 to rotate. Since the transmission rod 12 is engaged with the circular groove 161 on the surface of the transmission belt 16 through the protrusion 121 fixed on the surface, the drive motor 14 can drive the transmission rod 12 to rotate through the transmission belt 16; so that the transmission rod 12 drives the gear ring 23 to drive the rotating ring 21 to rotate through the transmission gear 13 fixed on the surface, so that the rotating ring 21 drives the oil pipe to rotate through the arc plate 22 and the clamping block 225 for brazing; and by setting the number of mounting frames 2 in each group to be two, the number of mounting frames 2 is increased, and the balance support points for the oil pipe are increased, and the user rotates the screw rod 17 so that the screw rod 17 can drive the mounting frame 2 without the gear ring 23 installed to move away from the mounting frame 2 fixed with the gear ring 23, so as to adjust the distance between the two mounting frames 2, and then adjust 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 provided to protect the screw 15 and the lead screw 17, so that during the brazing process, the bellows 18 can prevent the splashed welding slag from falling on the surface of the screw 15 and the lead screw 17, thereby improving the spiral transmission effect of the screw 15 and the lead screw 17, so that the practical application effect of the present invention is effectively improved, and by setting the bellows 18 to be made of silicone rubber material, the bellows 18 has good heat resistance and flame retardancy, thereby improving the service life of the bellows 18. ;
