[0017] 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.

[0018] See also Figures 1 to 3 The utility model provides a technical solution: an anti-corrosion spraying device for automobile parts processing, including a mechanical arm 3, a shaft 4 arranged at the top of the mechanical arm 3, and a mechanical arm 5 arranged at the top of the shaft 4. A mounting mechanism 50 is provided at the connection between the mechanical arm 5 and the shaft 4. The mounting mechanism 50 is composed of a limiting groove 501, a limiting block 502, and a fixing component 503. The limiting groove 501 is opened at the end of the mechanical arm 5, the limiting block 502 is arranged on the inner side of the limiting groove 501, and the bottom end of the limiting block 502 is fixed to the top of the shaft 4. The fixed component 503 is set at the connection between the limit groove 501 and the limit block 502. The designed installation mechanism 50 improves the process of spraying the anti-corrosion layer on the surface of the automobile parts by the spraying device. When the robot arm 2 5 needs to be installed, the robot arm 2 5 and the shaft 2 4 are fixed by bolt penetration. Therefore, during installation, the robot arm 2 5 needs to be moved several times to align the multiple mounting holes between the two. After alignment, the robot arm 2 5 needs to be supported by hand to fix the position of the robot arm 2 5, which is convenient for subsequent bolt penetration operations. Since the installation process requires multiple alignment of the mounting holes, there is an inconvenience. By setting a mounting mechanism 50 at the mounting position of the robot arm 2 5 and the shaft 2 4, the two can be automatically aligned with the mounting holes through the mounting mechanism 50 during installation, and a preliminary connection can be formed between the two, which is convenient for subsequent bolt penetration, thereby increasing the convenience of installation. The surface of the limit block 502 is in contact with the inner wall of the limit groove 501. The limit block 502 is a hollow cylindrical structure. The fixing assembly 503 consists of a fixing groove 5031, a fixing groove 5032, and a spring. The fixing groove 5031 is provided on the side of the robot arm 25, and the fixing groove 5032 is provided on the side of the limit block 502. The spring 5033 is arranged on the inner side of the fixing groove 5031 and the fixing groove 5032, and the spring assembly 5034 is arranged on the inner side of the fixing groove 5032. The cross section of the spring 5033 is a rectangular structure. The top of the spring 5033 is in the same horizontal plane as the outer surface of the robot arm 25. The bottom end of the robot arm 3 is provided with an axis 2, and the bottom end of the axis 2 is provided with a base 1.

[0019] In this embodiment, preferably, the spring assembly 5034 is composed of a movable groove 5034A, a movable column 5034B, and a spring body 5034C. The movable groove 5034A is opened at the bottom end of the spring 5033, and the movable column 5034B is arranged on the inner side of the movable groove 5034A. The bottom end of the movable column 5034B is fixed to the bottom end of the fixed groove 5032. The spring body 5034C is sleeved on the surface of the movable column 5034B. The spring body 5034C The two ends are respectively fixed to the top end of the spring 5033 and the bottom end of the fixed groove 5032. When the spring 5033 is pressed, the spring body 5034C is compressed, and the top end of the movable column 5034B is stuck in the inner side of the movable groove 5034A. When the spring 5033 loses the external force pressing on it, the spring 5033 is popped out under the elastic force of the spring body 5034C, and the movable column 5034B slides inside the movable groove 5034A at the same time.

[0020] The working principle and use process of the present invention are as follows: in the process of processing automobile parts, the anti-corrosion layer is sprayed by the spraying device. During operation, the spraying parameters, including color, paint type and spraying mode, are set by the external computer first. Then the robot arm will accurately move to the designated position and start the spraying work. When it is necessary to install the robot arm 2 5 and the shaft 2 4, the spring 5033 is pressed to make the spring 5033 embedded in the inner side of the fixing groove 5032, and then the bottom end of the robot arm 2 5 is fitted with the surface of the shaft 2 4, and the limit Block 502 is inserted into the inner side of the limiting groove 501, and the spring 5033 is released at the same time. Then the robot arm 2 5 is rotated to make the limiting block 502 rotate inside the limiting groove 501. When the spring 5033 is aligned with the fixing groove 5031, the spring 5033 is inserted into the inner side of the fixing groove 5031 through the spring assembly 5034, so that the rotation angle of the robot arm 2 5 is limited and the robot arm 2 5 is initially connected to the shaft 2 4. At this time, the multiple mounting holes between the robot arm 2 5 and the shaft 2 4 are aligned, and then multiple bolts are passed through to complete the installation operation of the robot arm 2 5.

[0021] 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.
