Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a friction welding tool for an anti-tipping turbine shaft. Background Technology

[0002] The turbine shaft is a key component in the turbocharger. Since the turbine and the welding shaft are made of different materials and the turbine shaft has a complex structure, it is not convenient to directly process it as a whole. Therefore, friction welding is used to connect the two.

[0003] When traditional friction welding tools are used with certain special turbines, the turbines inevitably tip over, posing safety risks to the welding process and causing quality problems. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-tipping friction welding tool for turbine shafts, which solves the problem that traditional friction welding tools inevitably cause the turbine to tip over when facing certain special turbines, posing a safety risk to the welding process and causing quality problems.

[0005] To achieve the above objectives, this utility model provides an anti-tipping friction welding tool for turbine shafts, including a positioning assembly and a limiting assembly. The positioning assembly includes a lower cover, an upper cover, a positioning ring, and fixing bolts. The upper cover is connected to the lower cover and located outside the lower cover. The positioning ring is connected to the upper cover and located outside the upper cover. There are multiple fixing bolts, each threadedly connected to the lower cover and passing through the lower cover, the upper cover, and the positioning ring. The limiting assembly is located between the lower cover and the upper cover.

[0006] The positioning component further includes multiple cylindrical pins, each of which is connected to the upper cover and passes through the upper cover and the positioning ring.

[0007] The limiting component includes a rotating disk and a handle. The rotating disk is rotatably connected to the lower cover and is located between the lower cover and the upper cover. The handle is detachably connected to the rotating disk and is located on the side of the rotating disk.

[0008] The limiting component further includes a slider and a connecting spindle. The slider is slidably connected to the upper cover and located between the upper cover and the positioning ring. The connecting spindle is detachably connected to the slider and passes through the slider and the rotating disk.

[0009] The upper cover has a sliding groove on its surface and a fixing groove on its surface. The turntable has a limiting groove on its surface and a swing groove on its surface.

[0010] This utility model discloses an anti-tipping friction welding tool for turbine shafts. The lower cover is used to fix the clamp in the welding position, the upper cover and the positioning ring are used to limit the limiting component, and the fixing bolt is used to fix the lower cover, the upper cover and the positioning ring. In use, the turbine shaft is placed between the upper cover and the positioning ring, and the handle is rotated, which simultaneously drives the rotating disk to rotate. The connecting mandrel is controlled by the limiting groove, which drives the slider to move along the groove to achieve the purpose of fixing the turbine shaft. This solves the problem that traditional friction welding tools inevitably cause the turbine to tip over when facing certain special turbines, which poses a safety risk to the welding process and also causes quality problems.

The positioning ring 103 is connected to the upper cover 102 and located outside the upper cover 102. Multiple fixing bolts 104 are threadedly connected to the lower cover 101 and pass through the lower cover 101, the upper cover 102, and the positioning ring 103. The limiting assembly is located between the lower cover 101 and the upper cover 102. The lower cover 101 is used to fix the clamp in the welding position. The upper cover 102 and the positioning ring 103 are used to limit the positioning component. The fixing bolt 104 is used to fix the lower cover 101, the upper cover 102 and the positioning ring 103. In use, the turbine shaft is placed between the upper cover 102 and the positioning ring 103. The handle 107 is rotated, which drives the rotating disk 106 to rotate. The connecting spindle 109 is controlled by the limiting groove 112, which drives the slider 108 to move along the slide groove 110 to achieve the purpose of fixing the turbine shaft.

[0019] The cylindrical pins 105 are multiple, and each cylindrical pin 105 is connected to the upper cover 102 and passes through the upper cover 102 and the positioning ring 103 respectively. The cylindrical pins 105 are used to limit the positioning ring 103 and the upper cover 102.
