The lower section of the support rod has a sliding cavity that slides with the sliding rod, and the lower side wall of the support rod has a guide groove that slides with the connecting crossbar. One end of the spring is connected to the sliding rod, and the other end of the spring is connected to the middle part of the support rod.

[0005] As a preferred embodiment of this utility model, the elastic support includes a connecting seat, a connecting plate, and an elastic pressure plate. The elastic pressure plate is connected to the connecting seat through the connecting plate. A C-shaped groove is formed between the elastic pressure plate, the connecting plate, and the connecting seat. The elastic pressure plate is tilted outward toward the side away from the connecting seat.

[0006] As a preferred embodiment of this utility model, it includes a support base and a connecting rod. The connecting rod is connected to the top of the support base and is perpendicular to the support base. A crossbar is provided on both sides of the end of the connecting rod. The positioning clamp is provided in two sets, and the two support rods are respectively connected to the ends of the crossbars.

[0007] As a preferred embodiment of this utility model, the support base is provided with a drive motor, a drive sprocket, a driven sprocket and a transmission chain.

Detailed Implementation

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a painting fixture for a motorcycle fuel tank, comprising a positioning fixture. The positioning fixture includes a support rod 1, a support crossbar 2, a spring 3, and a movable support rod 4. Two support crossbars 2 are provided and respectively disposed on the left and right sides of the first end of the support rod 1. The movable support rod 4 includes a sliding rod 41, a connecting crossbar 42, and an elastic support member 43. One end of the connecting crossbar 42 is connected to the side wall of the sliding rod 41, and the elastic support member 43 is connected to the other end of the connecting crossbar 42. The lower section of the support rod 1 is provided with a sliding cavity that slides with the sliding rod 41, and the lower side wall of the support rod 1 is provided with a guide groove 11 that slides with the connecting crossbar 42. One end of the spring 3 is connected to the sliding rod 41, and the other end of the spring 3 is connected to the middle part of the support rod 1.

[0021] In this invention, the movable support rod 4, with the cooperation of the spring 3 and the guide groove 11, can move back and forth along the length of the support rod 1, moving the movable support rod 4 towards the side closer to the support crossbar 2. This allows the elastic support member 43 of the movable support rod 4 to abut against the rear end of the inner cavity of the fuel tank workpiece. Moreover, the elastic support member 43 can better abut against the inner cavity of the fuel tank workpiece, while the support crossbar 2 abuts against the front end of the inner cavity of the fuel tank workpiece. This achieves quick positioning and fixing of the inner cavity of the motorcycle fuel tank workpiece 7 onto the positioning fixture, eliminating the need to clamp the surface of the motorcycle fuel tank workpiece 7. This facilitates the spraying treatment of the entire surface of the motorcycle fuel tank workpiece 7, ensuring the mass production of the automatic spraying process for motorcycle fuel tanks.

[0022] For example, the elastic support 43 includes a connecting seat 431, a connecting plate 432, and an elastic pressure plate 433. The elastic pressure plate 433 is connected to the connecting seat 431 through the connecting plate 432. A C-shaped groove is formed between the elastic pressure plate 433, the connecting plate 432, and the connecting seat 431. The elastic pressure plate 433 is tilted outward toward the side away from the connecting seat 431. In this way, the elastic support 43 effectively fits tightly against the inner cavity of the motorcycle fuel tank workpiece 7, reducing damage to the inner cavity wall of the motorcycle fuel tank workpiece 7.

[0023] Specifically, the motorcycle fuel tank painting fixture includes a support base 5 and a connecting rod 6. The connecting rod 6 is connected to the top of the support base 5 and is perpendicular to the support base 5. A crossbar 61 is provided on both sides of the end of the connecting rod 6. The positioning fixture is provided in two sets, with the two support rods 1 respectively connected to the ends of the crossbars 61. This allows for the simultaneous positioning and fixing of two motorcycle fuel tank workpieces 7, improving space utilization.

[0024] For example, the support base 5 is equipped with a drive motor, a drive sprocket, a driven sprocket, and a transmission chain (not shown in the figure). The drive sprocket is connected to the driven sprocket through the transmission chain. Both the transmission chain and the driven sprocket are rotatably engaged with the support base 5. The output shaft of the drive motor is connected to the drive sprocket, and the connecting rod 6 is connected to the driven sprocket. This allows the connecting rod 6 to rotate, thereby rotating the positioning fixture, facilitating the spraying process and reducing spraying dead angles.

[0025] For example, the support rod 1 is obliquely connected to the crossbar 61, and a reinforcing rib 44 is provided between the support rod 1 and the crossbar 61 to improve the structural strength.

[0026] For example, the upper left and right sides of the support rod 1 are symmetrically provided with reinforcing crossbars 45, and the ends of the reinforcing crossbars 45 abut against the inner cavity of the motorcycle fuel tank workpiece 7, thereby improving the stability of the positioning fixture and the motorcycle fuel tank workpiece 7 in positioning and fixing.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
