Abstract

A fixture for eccentric clamping of a wheel is composed of a base (1), a cylinder (2), a cylinder support (3), a connecting seat (4), a movable positioning seat (5), a guide rail sliding seat (6), a linear guide rail (7) and a fixed positioning seat (8), wherein the cylinder support (3), the linear guide rail (7) and the fixed positioning seat (8) are fixed on the base (1), the cylinder (2) is mounted on the cylinder support (3), an output shaft of the cylinder (2) is connected with the connecting seat (4), the connecting seat (4) is connected with the linear guide rail (7) via the guide rail sliding seat (6), the movable positioning seat (5) is fixed on the connecting seat (4), and the cylinder (2) is configured to drive the connecting seat (4) and the movable positioning seat (5) to move along the linear guide rail (7).

First claim

The invention claimed is:

1. A fixture for eccentric clamping of a wheel, being composed of a base, a cylinder, a cylinder support, a connecting seat, a movable positioning seat, a guide rail sliding seat, a linear guide rail and a fixed positioning seat, wherein the cylinder support, the linear guide rail and the fixed positioning seat are fixed on the base, the cylinder is mounted on the cylinder support, an output shaft of the cylinder is connected with the connecting seat, the connecting seat is connected with the linear guide rail via the guide rail sliding seat, the movable positioning seat is fixed on the connecting seat, and the cylinder is configured to drive the connecting seat and the movable positioning seat to move along the linear guide rail.

2. The fixture according to claim 1 , wherein the movable positioning seat and the fixed positioning seat are of step arc-shaped structures, and positioning surfaces are inclined surfaces.

3. The fixture according to claim 1 , wherein step height differences are 8-15 mm, platform surface widths are 8-15 mm, and inclined angles of the positioning inclined surfaces are 37-55 degrees.

4. The fixture according to claim 3 , wherein the step height differences are 12.7 mm, the platform surface widths are 12.7 mm, and the inclined angles of the positioning inclined surfaces are 45 degrees.

5. The fixture according to claim 1 , wherein the distance between the center of an initial position of the movable positioning seat and the center of the fixed positioning seat is 3.5-8.5 mm, and the center of the fixed positioning seat is superposed with the center of the fixture.

6. The fixture according to claim 1 , wherein the distance between the center of an initial position of the movable positioning seat and the center of the fixed positioning seat is 5 mm.

7. The fixture according to claim 1 , wherein the fixture allows a front wheel lip of the wheel to fall within platform surfaces of the movable positioning seat and the fixed positioning seat, the cylinder drives the connecting seat and the movable positioning seat to move along the linear guide rail, finally, the positioning inclined surface of the fixed positioning seat contacts the wheel lip, the center of the wheel is superposed with the center of the fixed positioning seat and superposed with the center of the fixture, and the clamping of the wheel is completed.
