Referring to fig. 1 to 2, a coating positioning device with scratch prevention function in an embodiment of the present invention includes a tray 20, a gasket 10, and a positioning cone 30. The tray 20 is provided with a cavity with an upward opening, the gasket 10 is fixed on the top of the tray 20, the gasket 10 is provided with a through hole 11, and the through hole 11 is opposite to the opening of the cavity.

In order to prevent the contact surface between the hub and the spacer from generating severe friction when the hub rotates, thereby damaging the surface of the hub, at least two scratch-proof protrusions 40 with elasticity are arranged on the spacer 10. The scratch prevention protrusions 40 lift up the hub so that the hub does not come into direct contact with the rigid shim 10. Preferably, the scratch-proof protrusion 40 is a conductive silicone member, and the silicone member has elasticity, so that the hub is not easily scratched; in addition, since the scratch prevention protrusion 40 may be conductive, the scratch prevention protrusion 40 may function as a conductive when electrostatically sprayed.

Further, as a preferred embodiment, the gasket 10 is provided with at least two mounting holes 12 for mounting the scratch prevention protrusions 40, and the tops of the scratch prevention protrusions 40 protrude from the upper end surfaces of the mounting holes 12. The scratch-resistant protrusion 40 is in interference fit with the mounting hole 12, and the anti-skid protrusion on the gasket 10 can be replaced as required according to the working condition of the anti-skid protrusion 40. Preferably, the number of the scratch prevention protrusions 40 is four, and the included angles between the connecting lines of two adjacent scratch prevention protrusions 40 and the through hole 11 are 90 °. The four anti-slip protrusions 40 are uniformly distributed, so that the hub is stably supported without inclination, and subsequent spraying is facilitated.

Further, as a preferred embodiment, an annular support portion is provided on the outer side of the top of the tray 20, a recessed portion 13 corresponding to the annular support portion is provided on the bottom surface of the gasket 10, and the annular support portion is fixed in the recessed portion 13 to limit the gasket 10 and prevent the gasket 10 from falling off. Furthermore, at least two clearance holes 21 are formed in the annular supporting portion, each clearance hole 21 corresponds to the scratch-proof protrusion 40 one by one, and each clearance hole 21 is located below the corresponding scratch-proof protrusion 40. When the anti-slip protrusions 40 are pressed down by the gravity of the hub and the lower ends of the anti-slip protrusions extend out of the mounting holes 12, the anti-slip protrusions do not directly abut against the annular supporting portion of the tray 20, and the tray 20 and the gasket 10 are tightly mounted.

The positioning cone 30 is movably arranged in the cavity through a lifting mechanism, and the positioning cone 30 penetrates through the through hole 11. Referring to fig. 3, the positioning cone 30 includes a circular table portion 31 and a cylindrical portion 32. In order to avoid the positioning cone 30 from extending excessively, the hub can be ensured to contact with the anti-slip protrusion 40 on the gasket 10, and the aperture of the through hole 11 of the gasket 10 is smaller than the inner diameter of the opening of the tray 20. Meanwhile, the diameter of the bottom surface of the circular table part 31 is smaller than the diameter of the end surface of the cylindrical part 32, the bottom of the circular table part 31 is connected with the end of the cylindrical part 32 to form a step part, and the shoulder of the step part can be abutted against the bottom surface of the through hole 11. When the step portion of the positioning cone 30 abuts against the bottom surface of the through hole 11 of the gasket 10, the positioning cone 30 cannot project upward any more.

When the hub is positioned in preparation for painting, the central bore of the hub is placed in alignment with the locating cone 30 and the hub is lowered by depressing the locating cone 30 so that the hub contacts the shim 10. Optionally, the lifting mechanism includes an elastic member 50, one end of the elastic member 50 is fixed to the bottom of the positioning cone 30, and the other end of the elastic member 50 is fixed to the bottom surface of the cavity. Optionally, the elastic member 50 is a telescopic spring. Further, the bottom surface of the positioning cone 30 is provided with a groove 33 for connecting the elastic member 50, and one end of the elastic member 50 is fixed in the groove 33, so that the connection between the elastic member 50 and the positioning cone is firmer.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
