Bearing positioning tool set

Abstract

A bearing positioning tool set includes a grip having an inner end fixed with a combining rod with a combining hole. One or more positioning press blocks to be fitted with the grip are respectively formed with different diameters and bored with a central insert hole and respectively formed with a first fitting member, a first holding edge, a second fitting member and a second holding edge. A combining member is combined with the combining hole of a grip. By having the fitting member and the holding edge of the positioning press block respectively contacting closely with the inner wall and the upper edge of a bearing, hammering force can be applied evenly to position smoothly and quickly the bearing in the insert hole of an axle. Further, each positioning press block is formed with two different diameters for matching with different-sized bearings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment of a bearing positioning tool set in the present invention, as shown in FIGS. 2, 3 and 6, includes a grip 1, one or more positioning press blocks 2, a combining member 3 and a tool box 4 combined together.

The grip 1 has an inner end fixed with a combining rod 10 extending outward and having a combining threaded hole 11 and an outer end formed with a hammering end 12.

The positioning press blocks 2 to be fitted with the grip 1 are respectively formed with different diameters and bored with an insert hole 20 in the center. Further, each positioning press block 2 is formed with a first fitting circular member 21, a first circular holding edge 22, a second circular fitting member 23 and a second circular holding edge 24.

The combining member 3 is to be threadably combined with the combining hole 11 of the grip 1 for fixing the positioning press block 2 in position.

The tool box 4 is used for depositing and storing the above-mentioned members of the tool set.

In using, as shown in FIGS. 2-5, firstly, pick out a positioning press block 2 with a suitable diameter and circumference according to the size of the inner diameter of a bearing (B) to be assembled. Next, the combining rod 10 of the grip 1 is inserted through the central insert hole 20 of the positioning press block 2 and then the combining member 3 is threadably combined with the combining threaded hole 11 of the grip 1 to fix the positioning press block 2 in position. In operating for positioning the bearing (B), as shown in FIGS. 4 and 5, firstly, the positioning press block 2 has its first fitting member 21 (or the second fitting member 23) closely contacting with the inner wall (B10) of the bearing (B) and its first holding edge 22 (or the second holding edge 24) closely and horizontally resting on the upper edge (B11) of the bearing (B). Next, the bearing (B) is driven into the insert hole (A) of an axle by striking the hammering end 12 of the grip 1 with a hammering tool (C). Thus, since the positioning press block 2 has its first fitting member 21 and its first holding edge 22 respectively and horizontally contacting closely with the inner wall (B10) and the upper edge (B11) of the bearing (B): therefore, the bearing (B) can smoothly and quickly be assembled and positioned in the insert hole (A) of an axle.

As can be understood from the above description, this invention has the following advantages.

1. The fitting member and the holding edge of the positioning press block can respectively contact closely with the inner wall and the upper edge of the bearing; therefore, during assembling, hammering force can be applied evenly and hence the bearing can be smoothly and quickly moved and positioned in the insert hole of an axle.

2. Since hammering force can be applied evenly, the bearing, when being assembled, can be smoothly and horizontally driven into the insert hole of the axle not to slant to any side, able to avoid wear to the inner wall of the insert hole of an axle or preventing the bearing from being damaged due to improper hammering.

3. The tool set of this invention is provided with different-sized positioning press blocks respectively formed with two different diameters for matching with different-sized bearings.

4. This invention is provided with a toolbox for facilitating depositing and storing the members of the tool set.

While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
