Description

Technical Field

[0001] This utility model relates to a tooling device, specifically an electric turning wheel tooling. Background Technology

[0002] In wind power generation equipment, due to the large size of the shaft system and its bearing housing, the installation of the shaft system on the bearing housing structure presents problems such as shaft concentricity and bearing clearance. Adjusting to ensure the installation accuracy of the shaft system is difficult. The conventional method is to fix the bearing housing structure and connect the shaft system horizontally to an external motor. The motor drives the horizontally set shaft system for adjustment. However, the gravity of the horizontally set shaft system causes a continuous radial force, which has a significant impact on the shaft system installation accuracy test and adjustment, and cannot meet the requirements of high-precision adjustment.

[0014] The beneficial effects of this utility model are:

[0015] 1. When adjusting the installation accuracy of the shaft system on the bearing housing structure, the shaft system is supported and locked to the mounting hole group on the rotary table via the flange at its lower end. Then, the telescopic bracket of any fixed seat is adjusted so that its abutment bracket aligns with the through bolts at the outer wall or seat foot holes of the bearing housing structure. Combined with the telescopic bracket of the other fixed seat, after telescopic extension or rotation positioning, its abutment bracket aligns with the through bolts at the outer wall or outer wall flange holes or other seat foot holes of the bearing housing structure, and is locked or abutted. This provides comprehensive anti-rotation positioning of the bearing housing structure from both lateral and longitudinal directions. The stable circumferential positioning of the bearing housing structure helps ensure the adjustment accuracy during rotary operation. The drive motor is controlled by a local controller or remote controller. The slewing bearing rotates via a transmission gear meshing or a reducer meshing with a transmission gear on an external gear ring outside the slewing support, or the drive motor is installed inside and driven by an inner ring meshing. The slewing support rotates, causing the slewing table to rotate. The slewing table drives the shaft system to rotate within the bearing housing structure, adjusting the installation accuracy of the shaft system, bearings, and bearing housings. In real time, the torque is fed back to the local controller or remote controller through the drive motor and reducer, using load changes and current fluctuations. Alternatively, the torque is fed back to the local controller or remote controller through torque sensors installed on each shaft. Information such as the rotation speed and number of revolutions monitored by each sensor is also fed back to the local controller or remote controller for external digital display or alarm. The slewing adjustment operation is convenient and the accuracy is controllable.

[0016] 2. The multi-ring mounting hole group on the rotary worktable, and the changeover worktable set on the rotary worktable with a changeover hole group of different diameters than the mounting hole group, can meet the locking of a large number of shaft systems of different specifications, improving the applicability of the tooling; according to the outer positioning anti-rotation hole position or seat foot position of different specifications and models of bearing housing structure, the abutment frame on the telescopic frame is adjusted to abut and pass through the anti-rotation locking bolt, so as to realize the fixed positioning of different bearing housing structures on the turning car tooling.

[0017] 3.
