Claim:
A bearing-positioning tool set comprising: a grip ( 1 ) having a hammering end opposite an inner end which is fixed with a combining rod ( 10 ) extending outward, said combining rod bored with a combining threaded hole ( 11 ); one positioning press block ( 2 ), said positioning press block to be fitted with said grip being bored with an insert hole ( 20 ) in a center of said positioning press block, each said positioning press block ( 2 ) formed with a first circular fitting member ( 21 ), a first circular holding edge ( 22 ), a second circular fitting member ( 23 ) and a second circular holding edge ( 24 ) which are arranged sequentially; wherein said first circular fitting member ( 21 ) has a conic shape with a large bottom near said first circular holding edge ( 22 ); and said second circular fitting member ( 23 ) has a conic shape with a large bottom near said second circular holding edge ( 24 ); and said first circular holding edge ( 22 ) has an outer diameter greater than that of said first circular fitting member ( 21 ) and also greater than that of said second circular fitting member ( 23 ); and an outer diameter of said first circular holding edge 22 is greater than that of said second circular holding edge ( 24 ); a circular protruding portion is formed between the first circular edge ( 22 ) and said second circular holding edge ( 24 ); three through holes formed around said insert hole ( 20 ) and formed in said positioning press block ( 22 ); a combining member ( 3 ) threadably combined with said combining threaded hole ( 11 ) of said grip ( 1 ) for fixing said positioning press block ( 2 ) in position; and wherein in operation, said combining rod ( 10 ) of said grip ( 1 ) is inserted through said insert hole ( 20 ) of said positioning press block ( 2 ) and then said combining member ( 3 ) is threadably combined with said combining threaded hole ( 11 ) of said grip ( 1 ) to fix said positioning press block ( 2 ) in position; a bearing is positioned to be assembled in the receiving hole of an axle when one of said first fitting member 21 and said second fitting member 23 closely contacts with an inner wall of said bearing with a respective one of said first holding edge ( 22 ) and said second holding edge ( 23 ) closely and horizontally resting on an upper edge of said bearing, and then said bearing can be driven into said receiving hole by striking said hammering end ( 12 ) of said grip ( 1 ) with a hammering tool; therefore, said bearing can smoothly and quickly be assembled and positioned in the receiving hole.
