Description

Technical Field

[0001] This application relates to the field of speed reducer spraying technology, and more particularly to a masking fixture for spraying. Background Technology

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a driven machine. It plays a role in matching speeds and transmitting torque between the prime mover and the driven machine or actuator, and is widely used in modern machinery. During speed reducer production, the speed reducer housing needs to be coated, allowing the paint to adhere to the outer surface of the speed reducer and preventing oxidation. Before coating the speed reducer housing, its internal cavity needs to be masked. Existing technologies require different coating masking designs depending on the size and material of the speed reducer housing. This not only occupies a large amount of space in the coating workshop but also wastes a significant amount of production costs for the enterprise. To solve this problem, this application discloses a masking fixture for coating. Utility Model Content

[0009] The outer ring of the second base cover plate is integrally provided with a second splicing part with a thickness of half that of the first splicing part. Several second mounting slots are arranged in a ring array on the first splicing part, and a third magnet block is installed in the interior of each of the several second mounting slots.

The first base mask and the second base mask are respectively detachably disposed in the first through cavity and the second through cavity.

[0031] The following will describe in detail how the first splicing shield, the second splicing shield, the first basic shield, and the second shield are spliced ​​together:

[0032] The outer ring of the first base cover plate of this application is integrally provided with a first splicing part 11 with a thickness of half that of the first splicing part.

Several fourth mounting slots 4111 are arranged in a ring array on the fourth splicing part, and a third iron block 120 is installed in the interior of the several fourth mounting slots respectively.

[0036] When the first splicing cover plate is fixed to the first base cover plate, the third splicing part is spliced ​​with the first splicing part and the second iron block is attracted to the second magnet block.

[0037] When the second splicing cover plate is fixed to the second base cover plate, the fourth splicing part is spliced ​​with the second splicing part and the third iron block is attracted to the third magnet block.
