Abstract

A tool set for assembling an automobile tapered bearing includes a pneumatic tool, a hammering tool, bolts and plural press blocks. The pneumatic tool consists of a rod having an annular blocking surface, a sleeve fitting around the rod, a compression spring received in the sleeve and fitting round a fitting portion of the rod, and a connector threadably combined with the rod. The hammering tool consists of a grip and a connecting rod extending from the grip and provided with a female-threaded hole, and the grip has a hammering end. Each press block is formed with an annular sloped surface and an annular blocking surface. One of the press blocks is selected to combine with the rod, so a pneumatic apparatus can drive the pneumatic tool to press and shift an automobile tapered bearing in an axle insert hole smoothly.

Claims (8)

1. A tool set for assembling an automobile tapered bearing comprising a pneumatic tool, a hammering tool, bolts and plural press blocks;

said pneumatic tool composed of a rod, a sleeve, a compression spring and a combining head, said rod having one end portion formed with a fitting portion, said rod formed with an annular blocking surface in an intermediate section, an insert portion formed to extend downward from said annular blocking surface and a lower end of the insert portion being disposed with a combining hole, said sleeve fitted around said rod and formed with a passageway in the interior, said passageway of said sleeve disposed therein with an annular blocking surface on an inner wall thereof near said lower end, said compressing spring fitted around said insert portion of said rod and received in said passageway of said sleeve, said compression spring having one end pushing against said annular blocking surface of said rod and another end pushing against said annular blocking surface of said sleeve, said connector threadably combined with said lower end of said rod, said connector provided with a male-threaded rod and an annular blocking surface, said connector having lower end bored with a female-threaded hole;

said hammering tool provided with a grip, said grip having one end formed with a combining stud bored with a female-threaded hole, said grip having a topside disposed with a hammering end; and

said press blocks respectively formed with different diameters, one of said press blocks selectably fitted with said connector of said pneumatic tool and fixed in position by said bolt, each said press block bored with an insert hole in a center of the press block and disposed with at least one annular sloped surface and at least one annular blocking surface.

2. The tool set for assembling an automobile tapered bearing as claimed in claim 1 , Wherein said hammering tool is provided with a connecting rod to be connected with said grip, said connecting rod having one end provided with a combining hole, said connecting rod having said another end extending outward to form a combining head with a female-threaded hole.

3. The tool set for assembling an automobile tapered bearing claimed in claim 1 , wherein said press blocks are made of metal.

4. The tool set for assembling an automobile tapered bearing claimed in claim 1 , wherein said press blocks are made of plastic.

5. The tool set for assembling an automobile tapered bearing as claimed in claim 1 , wherein a toolbox is provided for depositing foresaid tools and members.
