When welding the turbocharger, the rotating shaft is positioned by using a positioning unit, and the rotating shaft is driven to rotate by using the positioning unit. Under the action of the clamping member, and when the rotating shaft is not in contact with the impeller, the clamping member applies a clamping force of a preset degree to the impeller, and the clamping member ensures that the impeller and the rotating shaft are in a coaxial state. After the rotating shaft contacts the impeller, the rotating shaft in a rotating state can drive the impeller to rotate. At this time, the adjusting control member adjusts the clamping member to gradually increase the clamping force on the impeller until the impeller is in a stationary state. The clamping force of the clamping member on the impeller just copes with the welding of the impeller and the rotating shaft, thereby preventing the problem of deformation of the impeller caused by excessive clamping force on the impeller during welding. At the same time, it is ensured that the welding process can be completed smoothly, thereby improving the efficiency of welding the impeller and the rotating shaft.

Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to automatic welding equipment for processing a turbocharger. Background Art

[0002] Turbochargers play a vital role in the modern industrial field, especially in the automotive industry. The welding quality and efficiency of their impeller components are directly related to the performance and production efficiency of the entire equipment.

[0003] At present, when friction welding is performed on the impeller assembly of a turbocharger, the stationary impeller needs to be properly clamped. If the clamping force is too large, it will have an adverse effect on the impeller, such as causing the impeller to deform. This deformation will destroy the original structural integrity of the impeller and affect its dynamic balancing performance. Once the dynamic balancing performance is damaged, additional vibration and noise will be generated when the turbocharger runs at high speed, which will not only reduce the working stability of the equipment, but also shorten its service life. On the contrary, if the clamping force is too small, the impeller will rotate with the shaft during the welding process. In this way, the welding position will deviate, making it impossible to perform welding accurately, seriously affecting the welding quality. At the same time, the rotation of the impeller will also disrupt the normal welding process, resulting in a significant reduction in welding efficiency and an increase in the time and economic costs of production.

[0027] like Figures 1 to 4 As shown, an embodiment of the present invention provides an automatic welding device for processing a turbocharger, which includes a bracket 110, a clamping member and an adjustment control member.

[0028] The bracket 110 can be placed on the ground, and the bracket 110 is arranged in the left and right directions. A positioning unit is arranged at the left end of the bracket 110, and the positioning unit is used to position the rotating shaft. In this embodiment, the positioning unit includes a self-centering chuck, and the self-centering chuck can be a three-jaw chuck, and the three-jaw chuck can position the rotating shaft to a horizontal state. The positioning unit can also drive the rotating shaft to rotate. Specifically, the positioning unit also includes a driving motor, and the driving motor is fixedly arranged on the bracket 110. The power output shaft of the driving motor is coaxially fixedly connected with the three-jaw chuck, and the driving motor drives the three-jaw chuck and the rotating shaft to rotate synchronously.

[0029] The clamping member is used to clamp the impeller 150. The impeller 150 clamped by the clamping member is coaxial with the rotating shaft. The clamping member is initially set to apply a preset degree of clamping force to the impeller 150. Specifically, in this embodiment, the impeller 150 includes a first end face and a second end face. The first end face and the second end face are always in a coaxial state. The rotating shaft can contact the first end face of the impeller 150. In the initial state, the rotating shaft does not contact the first end face of the impeller 150. The clamping member applies a preset degree of clamping force to the impeller 150. The impeller 150 remains in a stable state under the action of the clamping member. At the same time, the impeller 150 is in a coaxial state with the rotating shaft.

[0030] The control button is used to adjust the clamping force of the clamping member on the impeller 150. When the impeller 150 is in contact with the rotating shaft and the rotating shaft is in a rotating state, since the clamping force of the clamping member on the impeller 150 is relatively small, at this time, the rotating shaft of the rotating shaft can drive the impeller 150 to rotate synchronously, and the welding of the rotating shaft and the impeller 150 cannot be achieved. The control button adjusts the clamping member to gradually increase the clamping force on the impeller 150 until the impeller 150 is in a stationary state. When the impeller 150 is in a stationary state, the rotating shaft and the impeller 150 can rotate relative to each other, thereby achieving friction welding of the rotating shaft and the impeller 150.

[0031] The automatic welding equipment for processing turbochargers of the present invention uses a positioning unit to position the rotating shaft when welding the turbocharger, and uses the positioning unit to drive the rotating shaft to rotate. Under the action of the clamping member, and when the rotating shaft is not in contact with the impeller 150, the clamping member applies a clamping force of a preset degree to the impeller 150, and the clamping member ensures that the impeller 150 and the rotating shaft are in a coaxial state. After the rotating shaft contacts the impeller 150, the rotating shaft in a rotating state can drive the impeller 150 to rotate. At this time, the control unit adjusts the clamping member to gradually increase the clamping force on the impeller 150 until the impeller 150 is in a stationary state. The clamping force of the clamping member on the impeller 150 just copes with the welding of the impeller 150 and the rotating shaft, thereby preventing the problem of excessive clamping force on the impeller 150 during the welding process, which causes the impeller 150 to deform. At the same time, it ensures that the welding process can be completed smoothly, thereby improving the efficiency of welding the impeller 150 and the rotating shaft.

[0032] In one embodiment, the clamping member includes a fixed shell 120, a top shell 130 and a first positioning rod 140; the fixed shell 120 is arranged on the bracket 110, and a fixed cavity is provided inside the fixed shell 120, and the axis of the fixed shell 120 is coaxially arranged with the rotating shaft. The top shell 130 is slidably arranged in the fixed cavity, and the impeller 150 can be placed inside the top shell 130. When the impeller 150 is placed inside the top shell 130, the first end face of the impeller 150 extends to the outside of the fixed shell 120. Specifically, a first opening is provided at the end of the fixed shell 120, and a second opening is provided at the end of the top shell 130. The first opening is connected to the second opening. When the impeller 150 is placed inside the top shell 130, the first end face of the impeller 150 extends to the outside of the fixed shell 120 through the first opening and the second opening, so that the first end face of the impeller 150 is in contact with the rotating shaft. The first positioning rod 140 is arranged in the fixed cavity, and the first positioning rod 140 is coaxially arranged with the fixed shell 120. One end of the first positioning rod 140 passes through the side wall of the tightening shell 130, so that the end of the first positioning rod 140 is located inside the tightening shell 130; the other end of the first positioning rod 140 can slide in the fixed cavity, and when the impeller 150 is placed inside the tightening shell 130, the impeller 150 can abut against the first positioning rod 140. At this time, the first positioning rod 140 can position the impeller 150 to ensure that the first end face of the impeller 150 is coaxial with the rotating shaft. When the tightening shell 130 slides in the fixed cavity, the tightening shell 130 and the first positioning rod 140 jointly clamp the impeller 150. When the tightening shell 130 slides in the fixed cavity, the first positioning rod 140 is in a stationary state in its own axial direction. The tightening shell 130 will push the impeller 150 to tightly abut against the first positioning rod 140, thereby clamping the impeller 150.

[0033] In one embodiment, the adjustment control unit includes an adjustment sleeve 160 and an adjustment spring 170. The adjustment sleeve 160 can be telescopically arranged. The adjustment spring 170 is arranged on the adjustment sleeve 160. The adjustment spring 170 is used to drive the adjustment sleeve 160 to return to an initial state when the length of the adjustment sleeve 160 changes. The adjusting sleeve 160 is coaxially sleeved on the outside of the first positioning rod 140, and the side wall of the adjusting sleeve 160 is slidably connected to the inner wall of the fixed shell 120. One end of the adjusting sleeve 160 is fixedly connected to the tightening shell 130. The other end of the adjusting sleeve 160 is provided with a threaded sleeve. The outer wall of the first positioning rod 140 is provided with a threaded groove. The threaded sleeve is provided on the first positioning rod 140. The adjusting sleeve 160 is connected to the first positioning rod 140 through the threaded sleeve. In the initial state, the adjusting sleeve 160 is in the shortest state. When the first positioning rod 140 moves along its own axial direction, the first positioning rod 140 drives the tightening shell 130 to move at the same time through the adjusting sleeve 160. The tightening shell 130 and the first positioning rod 140 jointly clamp the impeller 150, and the tightening shell 130 and the first positioning rod 140 are used to tighten the impeller 150. 50 applies a preset degree of holding force. At this time, when the rotating shaft contacts the first end face of the impeller 150, the rotation of the rotating shaft can drive the impeller 150 to rotate synchronously. Under the abutment between the impeller 150 and the first positioning rod 140, the first positioning rod 140 is driven to rotate synchronously. When the first positioning rod 140 rotates, the first positioning rod 140 rotates relative to the adjusting sleeve 160, and the adjusting sleeve 160 moves in the direction of its own axis. At the same time, the adjusting tension spring 170 is gradually stretched. Under the action of the adjusting tension spring 170, the tightening shell 130 has a tendency to slide along the direction of its own axis. The tightening shell 130 further squeezes the impeller 150, so that the rotation resistance of the impeller 150 gradually increases until the impeller 150 is in a stationary state, thereby completing the clamping of the impeller 150.

[0034] In one embodiment, a plug-in slot is provided on the first positioning rod 140, and a plug-in rod 180 is provided on the impeller 150. The plug-in rod 180 can be plugged into the plug-in slot, and when the impeller 150 rotates, the first positioning rod 140 can be driven to rotate around the first direction. Specifically, the plug-in rod 180 of the impeller 150 is provided on the second end face of the impeller 150, and the plug-in rod 180 is coaxially arranged with the second end face of the impeller 150. The cross-section of the plug-in slot of the first positioning rod 140 is set to a polygonal structure, and the plug-in rod 180 is set to a polygonal structure. When the first positioning rod 140 slides along its own axial direction, the plug-in rod 180 can be completely inserted into the plug-in slot. When a clamping force of a preset degree is applied to the impeller 150, the rotation of the impeller 150 is coordinated by the plug-in rod 180 and the plug-in slot, so that the first positioning rod 140 can rotate synchronously with the impeller 150.

[0035] In one of the embodiments, a reset rod 210 is provided on the inner wall of the fixed shell 120, and the reset rod 210 is coaxially arranged with the first positioning rod 140; a reset cavity with an opening facing away from the tightening shell 130 is provided inside the first positioning rod 140, and the end of the reset rod 210 can be inserted into the reset cavity. During the process of inserting the reset rod 210 into the reset cavity, the first positioning rod 140 can rotate around the second direction. During the process of withdrawing the reset rod 210 from the reset cavity, the first positioning rod 140 remains stationary. When the first positioning rod 140 and the tightening shell 130 do not clamp the impeller 150, the reset rod 210 is in the reset cavity. When the first positioning rod 140 and the tightening shell 130 gradually apply a preset degree of clamping force to the impeller 150, during this process, the reset rod 210 is gradually withdrawn from the reset chamber; after the impeller 150 and the rotating shaft are welded, the first positioning rod 140 moves along its own axial direction, during this process, the reset rod 210 is gradually inserted into the reset chamber, and the first positioning rod 140 rotates around the second direction to achieve the action of releasing the clamping of the impeller 150. Among them, the first direction is opposite to the second direction. Further, the reset rod 210 can be set to be telescopic. Specifically, the length of the reset rod 210 can be adjusted. When welding the impellers 150 and the rotating shafts of the same batch, the length of the reset rod 210 remains stable. When welding the impellers 150 and the rotating shafts of different batches, the length of the reset rod 210 changes, so that the angle of rotation of the first positioning rod 140 around the second direction can be adjusted.

[0036] Furthermore, the reset rod 210 includes a fixed section 211 and a sliding section 212. A sliding cavity is provided inside the fixed section 211. The fixed section 211 is fixedly provided on the inner wall of the fixed shell 120. One end of the sliding section 212 is slidably and sealedly provided in the sliding cavity, and the other end of the sliding section 212 can be inserted into the reset cavity. An adjusting tube 230 is provided on the fixed section 211. The interior of the adjusting tube 230 is connected with the sliding cavity. An adjusting rod 220 is provided on the adjusting tube 230.

Specifically, the reset groove 250 is provided in the sliding section 212 of the reset rod 210, the first end of the reset protrusion 260 is rotatably connected to the sliding section 212 of the reset rod 210, and a reset torsion spring is provided at the connection between the first end of the reset protrusion 260 and the sliding section 212. When the reset rod 210 is not inserted into the reset cavity, and under the action of the reset torsion spring, the second end of the reset protrusion 260 is in the second state. During the insertion of the reset rod 210 into the reset cavity, the reset protrusion 260 slides along the spiral groove 240, causing the first positioning rod 140 to rotate about the second direction; during the withdrawal of the reset rod 210 from the reset cavity, the reset protrusion 260 is squeezed by the spiral groove 240, so that the second end of the reset protrusion 260 is transformed from the second state to the first state, resulting in the first positioning rod 140 no longer rotating when the reset rod 210 moves relative to the reset cavity.

[0038] In one embodiment, a traction rod 270 is provided on the inner side wall of the fixed shell 120, and the traction rod 270 is used to traction the first positioning rod 140 to reciprocate along its own axis direction. Specifically, one end of the traction rod 270 is fixedly connected to the inner side wall of the fixed shell 120, and the other end of the traction rod 270 is fixedly provided with a rotating ring, which is coaxially rotatably sleeved on the outside of the first positioning rod 140.

[0040] In one of the embodiments, the side wall of the fixed shell 120 is provided with a first placement port connected to the fixed cavity in the external environment, and the side wall of the tightening shell 130 is provided with a second placement port connected to the inside of the tightening shell 130 and the fixed cavity.
