Description
Technical field
This utility model relates to a kind of for alternating current generator carbon brush lapping device.
Background technology
For coiling pattern alternating current generator, brush is vitals in coiling pattern alternating current generator, by being placed in brush holder support
Sliding contact in brush carrier and between the collector ring rotated in assembling, is connected external circuit with armature circuit.In order to ensure brush
Contacting effect with collector ring more good, the contact surface arc-shaped to be processed as of brush is corresponding with collector ring, and conventional method is
Crosus cloth is enclosed one week on motor collecting ring surface and rotates, repeatedly grind brush, now can produce a large amount of carbon dust at current collection
Ring surface retains, it is not easy to cleaning, after brushing with air, part carbon dust can enter into motor internal, also can be to motor product matter
Amount impacts, and the quality that brush grinds simultaneously is the highest.
Summary of the invention
The purpose of this utility model is that design is a kind of grinds high, easy to operate the grinding for alternating current generator carbon brush of brush precision
Mill apparatus.The technical solution of the utility model is: a kind of for alternating current generator carbon brush lapping device, main shaft (2) passes through c-type flat key
(3), bolt (4) be fixed on base (1), bearing cap (9) and angular contact ball bearing (13) are arranged on main shaft (2), its axis
Holding lid (9) diagonal angle contact ball bearing (13) and play position-limiting action, the bearing chamber rotating big lid (8) is arranged on angular contact ball bearing
(13), on outer ring, rotate together with big lid (8) put together on main shaft (2) by bolt (10), sand cylinder (14) is arranged on master
On axle (2), the first support set (15), the second support set (16) being sleeved on successively on main shaft (2), pressure is installed on main shaft (2) top
Cap (17), pressure cap (17) is put together on main shaft (2) by nut (18).
Operation principle of the present utility model:
1. this device is applicable to outside dimension and is: the grinding of D225, D280, D320, D350 carbon brush.D is collector ring external diameter
Size；
2. this utility model using method and advantage:
(1) sand cylinder (14) is arranged on main shaft (2), by the first support set (15), the second support set (16) pressure
Cap (17), nut (18) fasten, and wherein purpose is for preventing sand cylinder from rotating in process of lapping, affect brush and grind effect
Really.
(2) being fixed in abrasive band on sand cylinder (14), wherein the effect of sand cylinder is that instead of collector ring and fixes abrasive band.
(3) carbon brush holder is arranged on the installing hole rotating big lid (8) correspondence.Then carbon brush (19) is installed to carbon brush holder
On, the effect wherein rotating big lid is fixed carbon brush holder.
(4) reciprocating rotary rotates big lid (8), makes carbon brush (19) sand cylinder relatively perform relative motion, reaches the purpose ground；
During owing to grinding not on motor product, the carbon dust ground can be avoided to retain in a large number on collector ring surface, also will not be to motor
Product quality impacts, and also improves the quality that brush grinds simultaneously.
(5) advantage using vertical rotating mode to be ground brush is: first sand cylinder can be according to the chi of collector ring
Very little it is designed to different size, plays the effect replacing collector ring；Secondly sand cylinder is fabricated to drum forms, facilitates consolidating of abrasive band
Carbon dust meeting free-falling that is fixed, that produce in process of lapping, will not remain in sand cylinder surface, conveniently clear up, can be the most right
Many group brushes are ground, and are also convenient for observing the grinding situation of brush, the most more renew brush, make brush reach preferably and grind
Effect, is so conducive to motor to set up oxide-film between running center brush and collector ring.
