Abstract

The disclosure discloses a water blowing device which is composed of a wheel positioning rotating part and a wheel water blowing part. The water blowing requirement of the wheel can be met.

First claim

What is claimed is:

1. A water blowing device, being composed of a wheel positioning rotating part and a wheel water blowing part, wherein
the wheel positioning rotating part comprises a rack, a servo motor A, a connecting shaft, a first base, a rotating shaft, a rotary oil cylinder, a bearing A, a bearing end cover A, a second base, a bearing B, a bearing end cover B, a shaft, a shaft sleeve, contacts, springs, linear bearings and a synchronous cam;
the servo motor A and the first base are mounted on the rack; the rotating shaft is connected with an output shaft of the servo motor A through the connecting shaft; the rotary oil cylinder, the shaft sleeve and the second base are mounted on the rotating shaft; the bearing B and the shaft are sealed inside the second base by the bearing end cover B, and two ends of the shaft are respectively connected with an output shaft of the rotary oil cylinder and the synchronous cam; three or more linear bearings are uniformly mounted on a side wall of the shaft sleeve; a side wall of the synchronous cam is provided with three or more uniformly distributed arc surfaces; the springs and the linear bearings are arranged on the ends of outer sides of the three or more contacts in a penetrating manner, and the ends of inner sides of the three or more contacts are connected with the arc surfaces of the high-precision synchronous cam; two ends of the springs are respectively in contact with shaft end surfaces of the linear bearings and the contacts; inner side ends of the contacts tightly press against the synchronous cam all the time; and the rotating shaft is mounted on the first base through the bearing A and the bearing end cover A;
the wheel water blowing part comprises a mounting rack, spray nozzles, spray nozzle support frames, mounting seats and sliding chutes; and
the mounting rack is fixedly arranged on the rack and is provided with a series of sliding chutes, the mounting seats are mounted in the sliding chutes of the mounting rack, and the spray nozzles are mounted on the mounting seats through the spray nozzle support frames.

2. The water blowing device according to claim 1 , characterized in that the servo motor A drives the rotating shaft to rotate through the bearing A.

3. The water blowing device according to claim 1 , wherein the arc surfaces uniformly distributed on the side wall of the synchronous cam push a series of contacts to synchronously move towards an outer side of a radial direction, and a pitch diameter formed by the outer sides of the series of contacts is increased.

4. The water blowing device according to claim 1 , wherein in a reset process of the rotary oil cylinder, the inner side ends of the contacts are in contact with the synchronous cam all the time, and the series of contacts synchronously move towards an inner side of the radial direction.
