[0022] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] An embodiment of the present utility model discloses a polishing device for stainless steel skin of a hyperbolic elliptical spherical shell.

[0024] Referring to Figures 1-3 , a polishing device for stainless steel skin of a hyperbolic elliptical spherical shell includes a base 1 and a vertical plate 2. Two vertical plates 2 are fixedly arranged on both sides of the base 1. A cavity is opened inside the base 1. A plurality of suction holes are opened on the upper side of the cavity. A rubber pad is arranged on the upper surface of the base 1 to improve the connection stability between the stainless steel plate and the base 1. A piston plate 9 is slidably arranged inside the cavity. A double-acting cylinder 4 is arranged between the two vertical plates 2. The ends of the piston rods of the two double-acting cylinders 4 are fixedly provided with U-shaped plates 5. A roughing wheel 6 is rotatably arranged inside one U-shaped plate 5, and a finishing wheel 7 is rotatably arranged inside the other U-shaped plate 5. A first motor 8 is fixedly arranged on the front side of each of the two U-shaped plates 5. The output ends of the two first motors 8 are fixedly connected to the rotating shafts of the corresponding roughing wheels 6 and finishing wheels 7. A second motor 10 is fixedly arranged on the outer wall of the rear vertical plate 2. The output end of the second motor 10 is fixedly connected to one end of the corresponding rotating rod 3.

[0025] Referring to Figures 1-3 , a groove is opened in the middle of the lower side of the base 1. A transmission mechanism for driving the piston plate 9 to move is arranged inside the groove. The transmission mechanism includes a turntable 16 and a movable ring 13. A transmission rod 14 is rotatably arranged on the rear inner wall of the groove. The turntable 16 is fixedly sleeved on the front end of the transmission rod 14. A round pin 15 is eccentrically arranged on the front side of the turntable 16. The middle of the lower side of the piston plate 9 is fixedly provided with a vertical rod 12. The lower end of the vertical rod 12 extends into the inner side of the groove. The cross section of the vertical rod 12 is rectangular, so that the vertical rod 12 cannot rotate, that is, it can slide stably. The movable ring 13 is fixedly arranged at the lower end of the vertical rod 12. The front end of the round pin 15 passes through the movable ring 13. A retaining ring is fixedly sleeved on the front end of the round pin 15 to prevent the round pin 15 from slipping out of the movable ring 13 as much as possible. A third motor 11 is fixedly arranged on the outer wall of the lower end of the rear vertical plate 2. The output end of the third motor 11 is fixedly connected to one end of the transmission rod 14. The third motor 11 is a reduction motor, which can provide a large and stable driving force.

[0026] In the present utility model, during use, the third motor 11 drives the transmission rod 14 to rotate, which causes the turntable 16 to rotate, and further causes the round pin 15 to rotate with the transmission rod 14 as the axis. That is, the round pin 15 pushes one end of the movable ring 13, which causes the vertical rod 12 to pull the piston plate 9 to move, enabling multiple suction holes to suck air. That is, it can quickly position the stainless steel plate. Then, the first motors 8 on both sides drive the corresponding roughing wheels 6 and finishing wheels 7 to rotate, and the piston rod of the double-acting cylinder 4 extends, causing the roughing wheel 6 to contact the stainless steel plate. The second motor 10 drives the rotating rod 3 to rotate. During this period, the piston rod of the double-acting cylinder 4 extends synchronously, causing the roughing wheel 6 to always contact the stainless steel plate. That is, it can rough-grind the stainless steel plate. Then, the second motor 10 drives the rotating rod 3 to rotate 180 degrees, which can exchange the positions of the roughing wheels 6 and finishing wheels 7 on both sides. That is, it can quickly perform the finishing work after roughing without manual replacement, which can greatly improve the work efficiency.

[0027] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
