This patent application claims the benefit of Chinese Patent Application with Ser. No. 2021212936624 filed on Jun. 10, 2021, which is incorporated by reference herein.

The invention relates to a centering device, specifically, a device that achieves high-precision centering of wheels by means of special synchronizing gear meshing.

In the automotive wheel processing industry, the increasing labor costs promotes the industry's degree of automation, but automation needs high-precision positioning, so improving the positioning accuracy of wheels is a problem which must be solved by wheel processing enterprises.

The purpose of the invention is to provide a high-precision intelligent centering device.

In order to achieve the above purposes, the technical scheme of the present invention is: a high-precision intelligent centering device, consisting of a left and right symmetrical synchronous centering mechanism, including a rack, support, base, gear arm, two-way cylinder, base plate, linear guide rail, guide rail slide, connecting plate and positioning rod. The base plate is mounted on the rack by support; the connecting plate is connected to the linear guide rail through the guide rail slide, the four positioning rods are symmetrically fixed to the connecting plate, the gear arm and the base are hinged, the other end is hinged with the connecting plate, the gears of the left and right gear arms are partly engaged, two-way cylinder is placed into two output shafts respectively for connection with the left and right gear arms.

In the preference aspect of the invention, the gear parts of the left and right gear arms are partly engaged with high precision, and the structure can adjust the synchronization performance of the left and right centering mechanism with high precision.

In the preference aspect of the invention, in the process of synchronous clamping of the device, after aeration of two-way cylinder, the left and right gear arms are driven to expand towards two sides, through partly high-precision meshing of the gears of the left and right gear arms, it realizes high-precision synchronous centripetal motion of the four positioning rods distributed evenly on the left and right sides along the linear guide rail, and completes high-precision wheel centering.

In practice, the wheel moves to the device clamping position through the roller conveyor system, and then, the two-way cylinder begins to work, driving the upper part of the left and right gear arms to open towards both sides, through partly high-precision meshing of gears of the left and right gear arms, it finally realizes high-precision synchronous centripetal motion of positioning rods on the left and right sides, and completes the wheel high-precision synchronous centering work.

The invention can meet the needs of high precision centering of wheels in use, and the effect is ideal and efficient. The work is safe and reliable, with a high degree of automation, making it particularly suitable for mass production on the production line.
