Wheel mold spraying apparatus

Abstract

The present invention discloses a wheel mold spraying device, which is composed of a frame, a servo motor, a servo electric cylinder, a hollow shaft, a nozzle and the like. Four side molds of a wheel are respectively placed on four slide plates; hand wheels are rotated to adjust the slide plates to proper positions through lead screws and guide rails; the servo motor drives the rotation of the hollow shaft and the nozzle through belt wheels and a synchronous belt, and the nozzle is automatically opened; and through guide posts, the servo electric cylinder lifts the nozzle to the top end while rotating, in which case the process of spraying for the four side molds can be completed.

DETAILED DESCRIPTION OF THE INVENTION

(4) The details and working conditions of the specific device set forth in accordance with the present invention will be described below with reference to the accompanying drawings.

(5) The device is composed of a frame 1, a servo electric cylinder 2, guide posts 3, guide sleeves 4, a bottom plate 5, a lifting plate 6, a servo motor 7, a connecting frame 8, a small belt wheel 9, a synchronous belt 10, a rotating joint 11, a large belt wheel 12, a transition flange 13, a bearing block 14, a hollow shaft 15, hand wheels 16, lead screws 17, guide rails 18, slide plates 19, a spray gun 20, a connecting rod 21, a swivel head 22 and nuts 23. Four guide sleeves 4 are mounted on the bottom plate 5, four guide posts 3 mated with the guide sleeves 4 are mounted below the lifting plate 6. The servo electric cylinder 2 is fixed below the bottom plate 5, and an output end of the servo electric cylinder is hinged with the lower side of the lifting plate 6. The servo motor 7 with the small belt wheel 9 mounted on the output end thereof is fixed below the connecting frame 8. The connecting frame 8 is mounted at the left side of the lifting plate 6. The bearing block 14 is fixed above the lifting plate 6 through the transition flange 13. The hollow shaft 15 with the rotating joint 11 and the large belt wheel 12 fixed on the lower end thereof is fixed within the bearing block 14 through a bearing. The small belt wheel 9 and the large belt wheel 12 are connected with each other through the synchronous belt 10. The connecting rod 21 with the spray gun 20 fixed thereon is mounted on the top end of the hollow shaft 15 through the swivel head 22. The slide plate 19 with the nut 23 fixed therebelow is fixed, through the guide rail 18, onto a platform above the frame 1. The lead screw 17 is mated with the nut 23 and the hand wheel 16 is fixed at the tail end of the lead screw 17.

(6) During a working process of this device, four side molds of a wheel are respectively placed on four slide plates 19, and hand wheels 16 are rotated to adjust the slide plates 19 to proper positions through lead screws 17 and guide rails 18. The servo motor 7 drives the rotation of the hollow shaft 15 and the spray gun 20 through belt wheels and a synchronous belt 10, and the spray gun 20 is automatically opened. Through guide posts 3, the servo electric cylinder 2 lifts the spray gun 20 to the top end while rotating, in which case the process of spraying for the four side molds can be completed.

(7) The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
