Description

Bearing tool clamp for automobile steering column

Technical Field

The utility model belongs to the technical field of the mechanical skill and specifically relates to a bearing frock clamp for auto steering column.

Background

The bearing is widely used in various machines as a transmission part, and compared with other parts, the bearing is a small part and plays a role in playing a very important role. During the mechanical transmission process, when other parts move relative to each other on the shaft, the bearing can be used for reducing the friction force during the power transmission process, and meanwhile, the central position of the shaft can be kept fixed.

Usually, the bearing inner ring and the shaft are in interference fit, and most bearings are pressed on a shaft shoulder in an interference mode through a tool clamp. However, the existing bearing tooling clamp influences and damages the on-shaft characteristics of the output shaft, and if the spline is extruded and deformed, the output shaft cannot be assembled with other parts, and finally the output shaft is scrapped.

Therefore, a bearing tool clamp for an automobile steering column needs to be designed, damage to the spline of the output shaft can be avoided, and the problem of scrapping of the output shaft caused by the damage is solved.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a bearing frock clamp for auto steering tubular column, can avoid the destruction to the output shaft spline, solve the output shaft problem of scrapping that from this causes.

In order to achieve the purpose, the utility model provides a bearing frock clamp for auto steering column, including main anchor clamps, vice anchor clamps, main anchor clamps, vice anchor clamps cladding are outside the spline of output shaft, and main anchor clamps, vice anchor clamps are equipped with preceding spline groove and back spline groove with the contact position of output shaft spline, are equipped with round protruding structure between preceding spline groove and the back spline groove, and one side that protruding structure is close to preceding spline groove is equipped with dodges the structure.

The surface of the auxiliary clamp is provided with a convex block, the surface of the main clamp is provided with a groove, and the convex block is clamped into the corresponding groove.

And the connection position of the avoiding structure and the front spline groove and the connection position of the avoiding structure and the protruding structure are respectively provided with a fillet structure.

And bearings and pressing blocks are sleeved outside the main clamp and the auxiliary clamp.

And the main clamp is in clearance fit with the bearing or the pressing block.

And the auxiliary clamp is in clearance fit with the bearing or the pressing block.

Compared with the prior art, the utility model, designed a bearing frock clamp for steering column, set up at the contact position of main anchor clamps, vice anchor clamps and output shaft spline and dodge the structure, avoid anchor clamps extrusion output shaft spline and lead to the spline to warp, solve the output shaft problem of scrapping that from this causes.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1-2, the utility model provides a bearing frock clamp for steering column, including main anchor clamps, vice anchor clamps, main anchor clamps 4, the cladding of vice anchor clamps 5 is outside output shaft 1's spline, and main anchor clamps 4, vice anchor clamps 5 are equipped with front spline groove 6 and rear spline groove 7 with the contact position of output shaft 1 spline, are equipped with round protruding structure 8 between front spline groove 6 and the rear spline groove 7, and protruding structure 8 is equipped with and dodges structure 9 near one side of front spline groove 6.

Referring to fig. 3-4, a projection 51 is arranged on the surface of the auxiliary clamp 5, a groove 41 is arranged on the surface of the main clamp 4, and the projection 51 is clamped into the corresponding groove, so that the auxiliary clamp 5 and the main clamp 4 are positioned better, and the positions of the front spline groove 6, the rear spline groove 7, the protruding structure 8 and the avoiding structure 9 of the main clamp 4 and the auxiliary clamp 5 are ensured to correspond respectively.

Referring to fig. 5, a connecting position of the avoiding structure 9 and the front spline groove 6 and a connecting position of the avoiding structure 9 and the protruding structure 8 are respectively provided with a fillet structure 10. The rounded corner structure 10 avoids stress concentrations that may result from cutting a relief structure 9 out of the raised structure 8.

The utility model discloses at the during operation,

main anchor clamps

4, 5 overcoat of vice anchor clamps are equipped with bearing 2 and briquetting 3. The main clamp 4 is in clearance fit with the bearing 2 or the pressing block 3. The auxiliary clamp 5 is in clearance fit with the bearing 2 or the pressing block 3. Then the main clamp 4 and the auxiliary clamp 5 are pulled forwards, and simultaneously the side surface of the pressing block 3 is propped against the inner ring of the bearing 2, so that the bearing 2 is pressed onto the shaft shoulder of the output shaft 1 by the main clamp 4 and the auxiliary clamp 5. The avoiding structure 9 can avoid extruding the spline part of the output shaft 1 when the main clamp 4 and the auxiliary clamp 5 pull the output shaft 1 forwards.

From the test results, it can be seen that: use this the utility model discloses a bearing frock clamp does not cause destruction to the epaxial spline of tubular column output at the installation bearing in-process, and its intensity also satisfies anchor clamps designing requirement simultaneously.

The utility model discloses a bearing frock clamp for automobile steering column sets up at the contact position of main anchor clamps, vice anchor clamps and output shaft spline and dodges the structure, avoids anchor clamps extrusion output shaft spline and leads to the spline to warp, solves the output shaft disability problem that from this causes, has reduced the disability rate of tubular column output shaft, has also reduceed the processing cost of single tubular column.
