Abstract
Description
Technical Field
[0001] The utility model relates to the field of wind power gear boxes, in particular to a fast alignment clamping tool for wind power planetary wheel end surfaces. Background Art
[0002] As wind turbine gearboxes move toward higher power densities, the reliability and strength requirements for gearbox components are becoming increasingly stringent. Since the planetary gears are primarily helical gears, the screw holes on the end faces cannot be uniformly distributed and must be located in the middle of the tooth thickness, leaving no space for the tooth slots. This can affect batch processing and reduce efficiency. Utility Model Content
[0003] The utility model provides a wind turbine planetary wheel end surface fast alignment clamping tool, which aims to solve the shortcomings of the prior art and improve the processing efficiency of wind turbine planetary wheel end surface processing.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A wind turbine planetary wheel end face quick alignment fixture, characterized by:
[0006] The planetary gear is fixed on the workbench of the vertical machining center;
[0007] The tooth surface pressure plate, small contour block, small pressure plate, screw, and large contour block form the alignment structure combination, among which:
[0008] Place the small contour block on the workbench, align the tooth surface pressure plate with the tooth surface of one tooth groove, and place the other end of the tooth surface pressure plate horizontally on the small contour block;
[0009] A large equal-height block is placed on the workbench, the screw head of the screw is placed in the T-slot of the vertical machining workbench, the screw passes through the through hole opened on the small pressure plate, the nut is screwed on the external thread of the screw exposed to the small pressure plate, and the nut presses the small pressure plate so that the small pressure plate presses the tooth surface pressure plate.
[0010] Two or more alignment structure combinations are evenly distributed around the circumference of the axis of the planetary gear.
[0011] The screw head of the locking screw is placed in the T-slot of the workbench of the vertical machining center, the axis hole of the planetary gear is sleeved on the locking screw, and the planetary gear is placed on the workbench; the large pressure plate is placed on the upper end face of the planetary gear, and the locking nut is screwed on the external thread of the locking screw exposed to the large pressure plate and the large pressure plate is pressed to fix the planetary gear on the workbench.
[0012] The utility model is beneficial in that:
[0013] This solution incorporates a clamping fixture into the vertical machining center, enabling rapid positioning and clamping. After the first piece is aligned and machined, the machining center establishes a coordinate system to align the end face surface relative to the required position. As long as the toothed pressure plate and the large and small equal-height blocks in the fixture are fixed, the relative positions of the end face surfaces of subsequent batches of parts will also be fixed, ensuring the required position of the end face screw holes in batches. Subsequent batches of products can be placed directly in the same position as the first piece, and the machining center can then process directly according to the coordinates determined in the initial machining, greatly improving machining efficiency.

[0022] 2. Place the large pressure plate 3 on the upper end surface of the planetary gear 4, screw the fastening nut 2 onto the external thread of the fastening screw 1 exposed on the large pressure plate 3 and press the large pressure plate tightly to fix the planetary gear 4 on the workbench 100;
[0023] 3. Place the small contour block 7 on the workbench 100, align the tooth surface pressure plate 5 with the tooth surface of one tooth groove, and place the other end of the tooth surface pressure plate 5 horizontally on the small contour block 7;
[0024] 4. Place the large contour block 10 at a suitable position on the workbench 100. Place the screw head 91 of the screw rod 9 in the T-slot 102 of the vertical machining workbench 100. Pass the screw rod 9 through the through hole 60 provided in the small pressure plate 6. Thread the nut 8 onto the external thread of the screw rod 9 exposed to the small pressure plate 6. The nut 8 presses the small pressure plate 6 tightly. In this way, the small pressure plate 6 presses the tooth surface pressure plate 5.
[0025] 5. Install the alignment structure consisting of three sets of tooth surface pressure plates 5, small contour blocks 7, small pressure plates 6, screws 9, and large contour blocks 10 evenly distributed around the axis of the planetary gear 4 according to step 4;
[0026] 6. Mark and align the relative position of the first planetary gear end face screw hole 41, machine the end face screw hole 41 according to the angle requirements, and establish a coordinate system. As long as the positions of the tooth surface pressure plate 5, the large contour block 10, and the small contour block 7 remain unchanged, the relative position of the planetary gear end face screw hole 41 and the coordinate system can be fixed;
[0027] 7. After the first workpiece - planetary gear 4 is completed, just remove the locking nut 2 and the large pressure plate 3, replace the batch of planetary gears, align and align the large contour block 10 and the small contour block 7 that have been fixed and clamped on the workbench 100, and fine-tune the tooth surface pressure plate 5; then follow step 2 to complete the clamping and fixing, and the processing can be completed according to the relative position requirements of the coordinate system.
[0028] The end surface of the first planetary gear is aligned and clamped according to the angle requirements. After processing is completed, the subsequent batches of planetary gears can be directly processed according to the position requirements of the first piece to ensure the relative position requirements. There is no need to repeatedly mark and align, and the tooth surface pressure plate and equal-height blocks in the tooling do not need to be repeatedly disassembled.
