Positioning tool for wind power shaft forging processing

Abstract

This utility model discloses a positioning fixture for forging wind turbine shafts, including a guide seat with a bidirectional threaded rod rotatably connected inside. A shovel-shaped seat is symmetrically slidably mounted on the upper part of the guide seat, and the bidirectional threaded rod is threadedly connected to the shovel-shaped seat. A tray is mounted on the upper part of the shovel-shaped seat, and an arc-shaped tray is fixedly connected to the upper end of the tray. Guide wheels are evenly rotatably mounted on the arc-shaped tray. The guide seat includes a fixing plate, and a bearing seat is fixedly connected to the upper end of the fixing plate. After clamping and fixing the wind turbine shaft, the bidirectional threaded rod is rocked to push the shovel-shaped seat outward, causing the shovel-shaped seat to release the tray downward, lowering the tray and disengaging the guide wheels from the wind turbine shaft. After the wind turbine shaft is processed and lifted away, the bidirectional threaded rod is rocked again to bring the tray together, causing the shovel-shaped seat to return to its original position, restoring the arc-shaped tray and guide wheels to their original height. Positioning the wind turbine shaft using the arc-shaped tray and guide wheels reduces the difficulty of hoisting and positioning.

Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine shaft processing equipment, and in particular relates to a positioning fixture for wind turbine shaft forging processing. Background Technology

[0002] Wind turbine shafts are shaft-type components used in wind turbine generator sets to transmit torque and support the structure. They are one of the core components of wind power equipment and need to be hoisted onto a lathe, positioned, clamped, and then machined.

[0003] Because the wind turbine shaft itself is quite heavy, it is difficult to position it at its height using only hoisting equipment. Manually pushing it to position it on both sides is difficult, and repeatedly controlling the height during hoisting is also troublesome. This makes the positioning and clamping operation of the wind turbine shaft before processing quite difficult.

[0004] To address this issue, we propose a positioning fixture for wind turbine shaft forging to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of difficult positioning and clamping operations before wind turbine shaft processing, and to propose a positioning fixture for wind turbine shaft forging processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A positioning fixture for forging wind turbine shafts includes a guide seat with a bidirectional threaded rod rotatably connected inside. A shovel-shaped seat is symmetrically slidably mounted on the upper part of the guide seat, and the bidirectional threaded rod is threadedly connected to the shovel-shaped seat. A pallet is movably mounted on the upper part of the shovel-shaped seat, and an arc-shaped pallet is fixedly connected to the upper end of the pallet. Guide wheels are uniformly rotatably mounted on the arc-shaped pallet. The target wind turbine shaft is hoisted to the inside of the arc-shaped pallet, and the arc-shaped pallet is used to position the wind turbine shaft. The guide wheels guide the movement of the wind turbine shaft, allowing it to be inserted into the fixture of the target lathe. After clamping and fixing the wind turbine shaft, the bidirectional threaded rod is cranked to push the shovel-shaped seat outward, causing the shovel-shaped seat to release the pallet downward, lowering the pallet and disengaging the guide wheels from the wind turbine shaft. After the wind turbine shaft is processed and lifted away, the bidirectional threaded rod is cranked again to bring the pallet together, causing the shovel-shaped seat to return the pallet to its original position, restoring the arc-shaped pallet and guide wheels to their original height. Positioning the wind turbine shaft using the arc-shaped pallet and guide wheels reduces the difficulty of hoisting and positioning.

[0007] Preferably, the guide seat includes a fixed plate, and a bearing seat is fixedly connected to the upper end of the fixed plate. The bearing seat facilitates the guidance of the bidirectional threaded rod to rotate.

[0008] Preferably, the guide seat further includes a guide rod, which is symmetrically and fixedly connected to the side of the bearing seat. The guide rod guides the shovel-shaped seat to slide, increasing the stability of the shovel-shaped seat in the sliding direction.

[0009] Preferably, the bidirectional threaded rod includes a rotating block, on which threaded rods are symmetrically and fixedly connected. One end of one of the threaded rods is fixedly connected to a crank handle. Cranking the crank handle drives one of the threaded rods to rotate, which in turn drives the other threaded rod to rotate via the rotating block. This causes the two threaded rods to move the shovel-shaped seat in both directions, facilitating the opening or closing of the shovel-shaped seat through the bidirectional threaded rod.

[0010] Preferably, the bidirectional threaded rod further includes a rotating sleeve, which is rotatably connected to the crank handle. Holding the rotating sleeve while operating the crank handle prevents hand chafing.

[0011] Preferably, the tray includes a tray body, and a limiting shell is fixedly connected to the lower part of the tray body. The limiting shell is movably engaged within the shovel-shaped base, increasing the stability of the relative position between the tray body and the shovel-shaped base.

[0012] Preferably, the arc-shaped tray includes an arc-shaped plate, and the interior of the arc-shaped plate has through holes. The arc-shaped plate and guide wheels facilitate the positioning of the wind turbine shaft.

[0013] In summary, the technical effects and advantages of this utility model are as follows: The target wind turbine shaft is hoisted to the inside of the arc-shaped tray, the arc-shaped tray is used to position the wind turbine shaft, and the guide wheels are used to guide the movement of the wind turbine shaft so that it is inserted into the fixture of the target lathe. After the wind turbine shaft is clamped and fixed, the double-threaded rod is rocked to push the shovel-shaped seat outward, causing the shovel-shaped seat to release the tray downward, allowing the tray to descend and the guide wheels to disengage from the wind turbine shaft. After the wind turbine shaft is processed and lifted away, the double-threaded rod is rocked again to bring the tray together, causing the shovel-shaped seat to return the tray to its original position, and the arc-shaped tray and guide wheels to return to their original height. By positioning the wind turbine shaft using the arc-shaped tray and guide wheels, the difficulty of hoisting and positioning is reduced. Attached Figure Description

[0016] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0017] like Figure 1 As shown, a positioning fixture for forging wind turbine shafts includes a guide seat 2. A bidirectional threaded rod 3 is rotatably connected inside the guide seat 2. A shovel-shaped seat 6 is symmetrically slidably mounted on the upper part of the guide seat 2. The bidirectional threaded rod 3 is threadedly connected to the shovel-shaped seat 6. A tray 4 is movable on the upper part of the shovel-shaped seat 6. An arc-shaped tray 5 is fixedly connected to the upper end of the tray 4. Guide wheels 1 are uniformly rotatably mounted on the arc-shaped tray 5. The guide seat 2 is mounted on a target lathe.

[0018] like Figure 1 and 2 As shown, the guide seat 2 includes a fixed plate 23, and a bearing seat 21 is fixedly connected to the upper end of the fixed plate 23. The fixed plate 23 is fixedly connected to the target lathe. The bidirectional threaded rod 3 is guided to rotate by the bearing seat 21.

[0019] like Figure 1 and 2 As shown, the guide seat 2 also includes a guide rod 22, which is symmetrically and fixedly connected to the side of the bearing seat 21. The guide rod 22 is slidably inserted into the shovel-shaped seat 6, and the lower end of the shovel-shaped seat 6 is movably pressed against the fixed plate 23. The bearing seat 21 is movably locked against the inner wall of the shovel-shaped seat 6. The guide rod 22 guides the shovel-shaped seat 6 to slide, increasing the stability of the sliding direction of the shovel-shaped seat 6.

[0020] like Figure 1 and 3 As shown, the bidirectional threaded rod 3 includes a rotating block 31, with threaded rods 32 symmetrically fixedly connected to the rotating block 31. One end of one of the threaded rods 32 is fixedly connected to a crank handle 33. The rotating block 31 is rotatably mounted in the bearing housing 21, and the threaded rods 32 are threadedly mounted in the shovel-shaped seat 6. Cranking the crank handle 33 drives one of the threaded rods 32 to rotate, which in turn drives the other threaded rod 32 to rotate via the rotating block 31, causing the two threaded rods 32 to move the shovel-shaped seat 6 in both directions. Cranking the crank handle 33 drives one of the threaded rods 32 to rotate, which in turn drives the other threaded rod 32 to rotate via the rotating block 31, causing the two threaded rods 32 to move the shovel-shaped seat 6 in both directions. The bidirectional threaded rod 3 operates the shovel-shaped seat 6 to open or close.

[0021] like Figure 1 and 3 As shown, the bidirectional threaded rod 3 also includes a rotating sleeve 34, which is rotatably connected to the crank handle 33. Holding the rotating sleeve 34 allows the crank handle 33 to be rotated, preventing hand chafing.

[0022] like Figure 1 and 4As shown, the tray 4 includes a tray body 41, and a limiting shell 42 is fixedly connected to the lower part of the tray body 41. The limiting shell 42 is slidably locked onto the shovel-shaped seat 6, and the upper end of the shovel-shaped seat 6 is movably supported on the lower end of the tray body 41. By using the limiting shell 42 to be movably locked inside the shovel-shaped seat 6, the stability of the relative position between the tray body 41 and the shovel-shaped seat 6 is increased.

[0023] like Figure 1 and 5 As shown, the arc-shaped tray 5 includes an arc-shaped plate 51, with a through hole 52 inside the arc-shaped plate 51. The lower end of the arc-shaped plate 51 is fixedly connected to the upper end of the tray 4, and the guide wheel 1 is rotatably installed in the through hole 52. The wind turbine shaft is positioned using the arc-shaped plate 51 and the guide wheel 1.

[0024] Working principle: The target wind turbine shaft is hoisted to the inside of the arc-shaped tray 5. The arc-shaped tray 5 is used to position the wind turbine shaft, and the guide wheel 1 is used to guide the movement of the wind turbine shaft so that it is inserted into the fixture of the target lathe. After the wind turbine shaft is clamped and fixed, the double-threaded rod 3 is rocked to push the shovel-shaped seat 6 outward, causing the shovel-shaped seat 6 to release the tray 4 downward, causing the tray 4 to descend and the guide wheel 1 to disengage from the wind turbine shaft. After the wind turbine shaft is processed and lifted away, the double-threaded rod 3 is rocked again to bring the tray 4 together, causing the shovel-shaped seat 6 to return the tray 4 upward, and the arc-shaped tray 5 and guide wheel 1 to return to their original height. The wind turbine shaft is positioned by the arc-shaped tray 5 and guide wheel 1.
