The upper end of shape plate is equipped with boss, and positioning plate boss diameter of a circle is interior through consistent with verified brush holder ring, positioning plate and correction bucket
During assembling, four straight lines of positioning plate locating ring are corresponding with four straight troughs on correction bucket.
Deep groove ball bearing outer ring described in the technical solution of the utility model is with correcting in the bearing chamber of bucket lower face
Wall is connected using interference fit, and deep groove ball bearing inner ring is connected with base bearing position outer wall using interference fit.
Base described in the technical solution of the utility model is an inverted T-shaped, is set in the vertical edges of inverted T-shaped base
There is repeated hole.
The utility model is mainly used for direct current generator and brush holder support is fixed on brush by the threaded connection of bolt and brush holder support end
On bobbin brush holder mechanism correction, using the utility model frock can same station complete two-by-two symmetrical brush box relative distance and
Decile requirement determines, completes symmetrical brush box center line centering two-by-two, and brush holder support is processed with brush holder circle hole and positioning pin is pacified
Dress；The utility model is easy to operate, and labor intensity is low, and multiplexing can be reduced by being corrected debugging to brush holder using the utility model
Caused error during bit manipulation, can disposably complete to correct in brush box pair on the utility model, the works such as brush holder support positioning is fixed
Sequence, it is not only efficient, it is easy to operate, and also adjustment accuracy and reliability are high.
