Fixture for turning stator core of wind-driven generator

Abstract

The invention discloses a fixture for turning a stator core of a wind-driven generator, which is arranged on a work platform of a vertical lathe. The fixture comprises a spindle (3), a base (5), a relay shaft (4), a support ring (2) and a screw shaft (1), wherein the support ring (2) is formed by welding a positioning support ring and an anti-deformation support plate to form a whole, and is welded with the spindle (3); the relay shaft (4) is provided with an elastic device and is arranged on the spindle (3); and the screw shaft (1) consists of an inner screw shaft (6) and an outer inserted sleeve (7) arranged on the inner screw shaft (6), and is arranged on the spindle (3) through a screw device and a locking cover plate. The invention has the advantages that: the fixture has high generality, simply clamps the stator core, has high positioning accuracy and upper and lower coaxiality, reduces operation production cost, can effectively improve labor productivity by 2.5 to 3 times, and can meet the requirement of batch production.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamp for turning a stator core of a wind power generator. Background technique [0002] The wind power stator core has the following characteristics: the outer diameter of the iron core is larger and the height is higher; the iron core has waves; the back of the iron core has multiple ribs distributed and welded to the outer circle of the iron core, and the processing is interrupted cutting; the upper and lower ends of the iron core Strict requirements on the unevenness of the pressure plate; strict requirements on the diameter tolerance of the inner circle of the iron core; strict requirements on the coaxiality between the processing of the outer circle of the iron core and the inner circle of the iron core. It is still a blank. At present, it takes a lot of time to correct the workpiece when processing the wind power stator core. First, adjust the coaxiality of the core and the working platform, t...

[0002] The wind power stator core has the following characteristics: the outer diameter of the iron core is larger and the height is higher; the iron core has waves; the back of the iron core has multiple ribs distributed and welded to the outer circle of the iron core, and the processing is interrupted cutting; the upper and lower ends of the iron core Strict requirements on the unevenness of the pressure plate; strict requirements on the diameter tolerance of the inner circle of the iron core; strict requirements on the coaxiality between the processing of the outer circle of the iron core and the inner circle of the iron core. It is still a blank. At present, it takes a lot of time to correct the workpiece when processing the wind power stator core. First, adjust the coaxiality of the core and the working platform, then initially level the verticality of the core, and finally fine-tune the coaxiality of the core and the working platform. The axiality and verticality are adjusted before turning the upper and lower ends of the outer circle of the core. During the entire operation process, the time spent on correcting the stator core is roughly equal to the actual turning time, and sometimes the time for correcting the workpiece is much longer than the actual time. Turning processing time is extremely low, and the production efficiency is extremely low. Due to the complicated calibration and positioning operations, large errors, and unstable processing quality, it cannot meet production needs.
