[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] The utility model provides a spray paint fixture, such as Figure 1-2 As shown, a paint spraying fixture of an embodiment includes a supporting assembly 10, and the supporting assembly 10 includes a clamping member 11. The clamping member 11 is engaged with a product 30 to fix the product 30. In a first direction, two opposite sides of the clamping member 11 are respectively in point contact with the product 30 to limit the movement of the product 30 along the first direction, and / or, in a second direction, two opposite sides of the clamping member 11 are respectively in point contact with the product 30 to limit the movement of the product 30 along the second direction.

[0028] In the paint spraying clamping fixture of the present invention, the product 30 is clamped and fixed by the clamping part 11, and the clamping part 11 is engaged and connected with the product 30 and there is point contact between the two. The clamping part 11 has a minimum shielding area during the process of clamping and fixing the product. The product 30 only needs to be clamped once, and the requirements of spraying paint on the front and back of the product 30 can be completed at one time, thereby reducing production costs and improving production efficiency.

[0029] In this embodiment, during the process of the clamping member 11 being engaged with the product 30, the clamping member 11 on both sides of the first direction and on both sides of the second direction are in point contact with the product 30, so as to clamp and fix the product 30 and prevent the product 30 from falling during the spraying process. Figure 3-4 As shown, in the first direction, the two opposite sides of the clamping member 11 are in point contact with the product 30 to restrict the product 30 from moving along the first direction; Figure 5-6 In the second direction, the opposite sides of the clamp 11 make point contact with the product 30 to limit the movement of the product 30 along the second direction, preventing the product 30 from falling during the spraying process. The first direction is perpendicular to the second direction. In the process of the clamp 11 being engaged and connected with the product 30, the clamp 11 makes point contact with the product 30 in two mutually perpendicular directions, which can achieve the minimum contact area between the clamp 11 and the product 30 while fixing the product 30. The minimum contact area between the two minimizes the area of ​​the product 30 that is blocked during the spraying process, so that the product 30 only needs to be clamped once to complete the front / back spraying, which can meet the demand for one-time spraying of the front / back, thereby reducing production costs.

[0030] It can be understood that the clamping member 11 can also achieve clamping and fixing of the product 30 by point contacting the product 30 on two opposite sides in the first direction; or, the clamping member 11 can also achieve clamping and fixing of the product 30 by point contacting the product 30 on two opposite sides in the second direction.

Specifically, the first curved surface 111 and the second curved surface 112 can be regarded as a spherical surface as a whole. When the two are in contact with the product 30 respectively, the surface of the product 30 in contact with the first curved surface 111 and the second curved surface 112 is a plane. During the clamping process, the product 30 is regarded as being inserted into the clamping member 11 from top to bottom and being connected with the clamping member 11 by snapping. At this time, the first curved surface 111 and the second curved surface 112 are respectively in point contact with two planes arranged opposite to the product 30, so as to limit the movement of the product 30 in the left and right directions.
