Description

Technical Field

[0001] The invention relates to a tooling device, in particular to a turning device. Background Art

[0002] In the current compressor or turbine rotor assembly process, the blades are assembled after the discs form the overall rotor structure. Therefore, when a single disc is flipped during processing and rotor assembly, it is mostly in a bladeless state, and the flipping difficulty is low. However, when the disc needs to be flipped with blades attached, the flipping difficulty increases. The existing flipping bracket has a complex structure, and the operator has high labor intensity. When multiple discs are lined up to be flipped, the flipping efficiency is low, and when the disc is displaced during flipping, it is easy to cause blade collision damage. Summary of the invention

[0003] The purpose of the present invention is to provide a convenient and efficient compressor wheel turning bracket for improving work efficiency.

[0004] The object of the present invention is achieved in that:

[0005] The present invention discloses a convenient and efficient compressor wheel flipping bracket, which is characterized by comprising a bracket, a fixing plate, a handle, a worm gear reducer, a driving shaft, a driven shaft, a driving shaft fixing seat, a driven shaft fixing seat, a bearing seat A, and a bearing seat B. The driving shaft fixing seat and the driven shaft fixing seat are respectively fixed to the inner sides of both ends of the bracket, and the two ends of the fixing plate are respectively fixed below the driving shaft fixing seat and the driven shaft fixing seat. The bearing seat A is fixed on the bracket outside the driving shaft fixing seat, and the bearing seat B is fixed on the bracket outside the driven shaft fixing seat. Both the bearing seat A and the bearing seat B are equipped with built-in double-row axial roller bearings. The driving shaft is located in the double-row axial roller bearings of the worm gear reducer, the driving shaft fixing seat and the bearing seat A. The driving shaft located in the worm gear reducer is connected to the worm gear reducer via a flat key A, and the worm gear reducer is connected to the handle. The driving shaft located in the driving shaft fixing seat is connected to the driving shaft fixing seat via a flat key B, and the driven shaft is located in the double-row axial roller bearings of the driven shaft fixing seat and the bearing seat B.

[0006] The present invention may also include:

[0007] 1. A U-shaped groove for removing the wheel disc is provided on the fixed plate.

[0008] 2. A washer B is arranged between the fixed plate and the wheel disc. The washer B is in the form of a stepped shaft and has a clearance fit with the fixed plate and the wheel disc.

[0009] 3. Insert the stop pin that fixes the wheel disc position into the end face of the bearing seat B.

[0010] 4. The handle rotates through the worm gear reducer and flat key A to drive the driving shaft to rotate. The driving shaft drives the driving shaft fixing seat to rotate through flat key B, thereby driving the fixing plate and the wheel disc to flip together with the driven shaft.

[0011] The advantages of the present invention are: the present invention can safely and quickly realize the flipping of the compressor wheel or turbine disc with blades, reducing the labor intensity of the operator, adding a washer B at the bolt fastening position of the wheel and the fixing plate, which is matched with the wheel with a small gap to realize the radial positioning of the wheel and prevent the blades from colliding with the nearby bearing seat. The U-shaped groove on the fixing plate can also enable the wheel to be quickly installed, and can also be quickly disassembled after the flipping operation is completed, which greatly improves the work efficiency when multiple wheels are waiting to be flipped.

[0015] The present invention is described in more detail below with reference to the accompanying drawings:

[0016] Combination Figure 1-3 The present invention is a convenient and efficient compressor wheel flip bracket. The main components include: a handle assembly 1, a worm gear reducer 2, a flat key A3, a double-row axial roller bearing 5, a driving shaft 6, a flat key B7, a bearing cover A8, a bearing seat A9, a driving shaft fixing seat 10, a washer A12, a washer B13, a driven shaft fixing seat 14, a bearing seat B15, a bearing cover B16, a stop pin 18, a driven shaft 19, a cylindrical pin 21, a fixing plate 22, a lifting eye screw 24, a bracket 25, etc.

[0017] The bearing seats A9 and B15 are both equipped with double-row axial roller bearings 5. The driving shaft fixing seat 10 and the driven shaft fixing seat 14 are fixed to the two ends of the bracket 25 by bolts, and the two ends of the fixing plate 22 are respectively fastened to the driving shaft fixing seat 10 and the driven shaft fixing seat 14 by cylindrical pins 21, and the main structure is connected to the driven shaft 19 by the driving shaft 6. The wheel is placed on the fixing plate 22 and fastened by bolts. Turn the handle 1 to complete the wheel flip, and insert the stop pin 18 to fix it after flipping into place.

[0018] The wheel disc is fastened to the fixing plate 22 by bolts. By turning the handle 1, the worm gear reducer 2 drives the driving shaft 6 and the bearing through the flat key A3. The driving shaft 6 transmits the power to the driving shaft fixing seat 10 through the flat key B7, thereby driving the fixing plate 22 and the wheel disc to flip together with the driven shaft 19 on the opposite side and finally completing the wheel disc flipping operation.

[0019] The bolts connecting the wheel disc and the fixed plate 22 have a washer A12 installed between the upper part and the wheel disc. Between the fixed plate 22 and the wheel disc, the radial displacement of the wheel disc is limited by a washer B13, which is in the form of a stepped shaft and has a small clearance fit with the fixed plate 22 and the wheel disc.

[0020] The ends of the bearing seats A and B are respectively installed with bearing glands A and bearing glands B, and the bracket is installed with eye screws 24.

[0021] A U-shaped groove is opened on the side of the fixing plate 22. After the wheel disc is turned over, the fastening bolts are loosened, and the gasket B13 is removed. Then, a lifting device is used to lift the wheel disc away from the fixing plate 22 and move it horizontally out from the side U-shaped groove position.
