[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example:

[0026] See also Figure 1-Figure 3The utility model provides a rust removal device for precision castings, including an ultrasonic cleaning and rust removal bin 1. The ultrasonic cleaning and rust removal bin 1 has an oblique contraction structure. A discharge port 2 is provided on the top of the ultrasonic cleaning and rust removal bin 1. The contraction end of the ultrasonic cleaning and rust removal bin 1 is located outside the discharge port 2 and a discharge port 3 is provided. A motor 4 is fixedly installed at the other end of the ultrasonic cleaning and rust removal bin 1. The rotating shaft of the motor 4 extends into the ultrasonic cleaning and rust removal bin 1 and a rotating cylinder 5 is fixedly installed. The rotating cylinder 5 is matched with the obliquely contracted inner cavity of the ultrasonic cleaning and rust removal bin 1. The outer side surface of the rotating cylinder 5 is concavely provided with an arc-shaped storage groove 6 around the axis to match the width of the discharge port 2. The arc-shaped storage groove 6 is arranged obliquely downward toward the contraction end of the ultrasonic cleaning and rust removal bin 1.

[0027] Specifically, the size of the discharge port 3 corresponds to the lower end of the arc-shaped storage groove 6, so that the precision casting after rust removal can automatically slide out from the discharge port 3.

[0028] Specifically, such as Figure 1 As shown, the ultrasonic cleaning and rust removal chamber 1 is provided with an opening at the end of the motor 4 corresponding to the arc-shaped storage groove 6, which can directly push the casting.

[0029] Specifically, such as Figure 3 As shown, the rotating cylinder 5 is a cavity structure. The cavity opening of the rotating cylinder 5 facing the contraction end of the ultrasonic cleaning and rust removal chamber 1 is connected to the outside. A sealing plate is provided at the cavity opening of the rotating cylinder 5 connected to the rotating shaft of the motor 4. The sealing plate is fixedly connected to the rotating shaft of the motor 4 to reduce weight and make room for rust removal liquid to be filled.

[0030] Specifically, such as Figure 2 As shown, a drain pipe 7 is provided at the lower position of the contraction end of the ultrasonic cleaning and rust removal chamber 1 to facilitate draining.

[0031] Specifically, such as Figure 2 As shown, the discharge port 3 is arranged at the last position of the counterclockwise rotation of the rotating cylinder 5, the rust removal stroke is long, and the liquid level of the rust removal liquid is not lowered.

[0032] Working principle:

[0033] Pour the rust removal liquid into the ultrasonic cleaning and rust removal bin 1, seal the drain pipe 7, and when the arc-shaped storage groove 6 of the rotating drum 5 rotates to the position of the discharge port 2, push the precision casting at the opening position of the ultrasonic cleaning and rust removal bin 1, and the motor 4 drives the rotating drum 5 to rotate and rotate the casting into the rust removal liquid. During the slow rotation, the rust removal of the casting is completed. When the rust removal is completed, the casting rotates to the position of the discharge port 3. Because the arc-shaped storage groove 6 is inclined toward the discharge port 3, the casting automatically slides out from the position of the discharge port 3, and then returns to the position of the discharge port 2.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
