[0030] An engine cylinder body spraying device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 The utility model aims to provide an embodiment of an engine cylinder spraying device. The utility model aims to solve the problem that the motorcycle engine cylinder has a complex shape and is difficult to spray in place, reduce the spraying dead angle, and improve the spraying efficiency.

[0032] In this embodiment, the spraying device includes a frame, and the frame is provided with a rotation mechanism and a spraying mechanism.

[0033] Reference Figure 1 The self-rotation mechanism includes an inner expansion shaft 1 and a turntable 2. The axis of the inner expansion shaft 1 is horizontally arranged. One end of the inner expansion shaft 1 is installed on the turntable 2 and driven to rotate by the turntable 2. One end of the inner expansion shaft 1 is inserted into the inner side of the cylinder body and fixed to the cylinder body with internal support.

[0034] Reference Figure 2 The spraying mechanism includes a translation component 3 and a rotation component 4. The translation component 3 can drive the rotation component 4 to translate in two mutually perpendicular horizontal directions. The rotation component 4 can rotate horizontally. The rotation component 4 is equipped with a spray gun 5, and the spray gun 5 can be located on both sides of the radial direction of the cylinder body of the inner expansion shaft 1.

[0035] In some specific embodiments of the present invention, the inner expansion shaft 1 can be a gas expansion shaft to increase the contact area and reduce the possibility of loosening.

[0036] In some specific embodiments of the utility model, the inner expansion shaft 1 can be made into a four-link structure and pulled and pushed by a cylinder, so that two parallel connecting rods of the four-link structure move radially along the inner expansion shaft 1 to change the gap between the inner expansion shaft 1 and the rod body, thereby providing strong internal support and adapting to the situation where the inner hole of the cylinder body blank is a flat hole, thereby meeting actual use needs.

[0037] In some specific embodiments of the present invention, the translation assembly 3 can include two vertically arranged ball screw structures or screw sleeve structures, and also include a linear guide rail for support, so that the composition of the translation assembly 3 is similar to the driving structure of the worktable of the machine tool, thereby allowing the rotating assembly 4 to be at any position within the travel range to meet the use requirements.

[0038] In summary, in this embodiment, by setting the inner expansion shaft 1 and the turntable 2, on the one hand, the inner expansion shaft 1 is positioned in cooperation with the inner surface of the cylinder body, which can not only fix the cylinder body, but also shield the inner surface of the cylinder body, which is convenient for subsequent machining; on the other hand, the turntable 2 can drive the inner expansion shaft 1 to rotate, so that the spraying device can spray the radial circle of the cylinder body to reduce the dead angle of spraying.

[0039] It is easy to understand that, by setting the translation assembly 3 in this embodiment, the spray gun 5 can be moved along the axial direction of the cylinder body, so that each outer surface position along the axial direction of the cylinder body can be sprayed, thereby increasing the spraying area and helping to reduce the spraying dead angle.

[0040] It is easy to understand that, in this embodiment, by setting the translation component 3 and the rotation component 4, the spray gun 5 can be located on both sides of the radial direction of the cylinder body on the inner expansion shaft 1, so that the spray gun 5 sprays toward the cylinder body in two opposite directions. On the one hand, there is an angle between the spray gun 5 and the cylinder body to produce a spraying shadow area, thereby reducing the spraying dead angle. On the other hand, repeated adjustment of the spray gun 5 is avoided, thereby improving the stability and service life of the spraying device.

[0041] It is easy to understand that in this embodiment, by setting the translation component 3 and the rotation component 4, on the one hand, the spray gun 5 has two opposite angles in the radial direction of the cylinder body, which meets the need for circumferential spraying without dead angles. On the other hand, the spray gun 5 has an angle in the axial direction of the cylinder body, and the angles can also exist at two and opposite angles, which meets the need for axial spraying without dead angles.

[0042] Moreover, the angle of the spray gun 5 in the axial direction of the cylinder body can also be changed into multiple angles according to the adjustment of the rotating assembly 4, thereby improving the function of the spray device.

[0043] Therefore, in this embodiment, the working principle of the spraying device is as follows:

[0044] 1. Place the cylinder body on the inner expansion shaft 1, prop up the inner expansion shaft 1, so that the cylinder body is fixed on the inner expansion shaft 1, and then, the turntable 2 works to make the inner expansion shaft 1 rotate, thereby driving the cylinder body to rotate.

[0045] 2. The translation component 3 moves the spray gun 5 along the axial direction of the inner expansion shaft 1. At the same time, the spray gun 5 sprays so that the circumferential surface of the cylinder body is sprayed. In addition, during the translation of the spray gun 5, the rotation component 4 can work to adjust the angle between the spray gun 5 and the axis of the cylinder body, so that the spray gun 5 can spray the surface of the heat sink of the cylinder body to avoid the spraying being limited to the top and root of the heat sink.

[0046] 3. When spraying on one side is completed, the translation assembly 3 causes the spray gun 5 to move radially along the inner expansion shaft 1. At the same time, the rotation assembly 4 causes the spray gun 5 to rotate, so that the spray gun 5 can spray from the other side of the cylinder body, avoiding the existence of a spray shadow in the circumference of the cylinder body due to the fixed angle of the spray gun 5.

[0047] In some specific embodiments of the present invention, the spray gun 5 can be prevented from rotating during the translational spraying process. Instead, the spray gun 5 is used to spray on both sides of the cylinder body to eliminate spraying dead angles. As a result, local over-spraying can be avoided and paint consumption can be reduced, while the working time of the rotating component 4 can be reduced, energy consumption can be reduced, and spraying efficiency can be improved.

[0048] In some specific embodiments of the present invention, the spray gun 5 can be located at two opposite upper oblique positions of the cylinder body of the inner expansion shaft 1 .

[0049] It is easy to understand that in this embodiment, by positioning the spray gun 5 obliquely above the inner expansion shaft 1 , the spray gun 5 is also configured to spray obliquely downward, thereby reducing the possibility of spraying toward the operator and lowering the risk of the operation.

[0050] In some specific embodiments of the present invention, the rotating assembly 4 can include an arc frame 6, the inner side of the arc frame 6 faces the inner expansion shaft 1, the bottom end of the arc frame 6 is connected to a motor 7, the motor 7 drives the arc frame 6 to rotate, and a spray gun 5 is installed on the top end of the arc frame 6.

[0051] It is easy to understand that in this embodiment, by making the rotating assembly 4 include the arc frame 6, it is convenient for the spray gun 5 to bypass the inner expansion shaft 1, thereby shortening the stroke of the translation assembly 3 and reducing the manufacturing cost.

[0052] In some specific embodiments of the present invention, the arc-shaped frame 6 may include a C-shaped frame or an L-shaped frame.

[0053] It is easy to understand that in this embodiment, by making the arc frame 6 include a C-shaped frame or an L-shaped frame, it is also convenient to manufacture by bending a rod, thereby reducing the manufacturing difficulty.

[0054] In some specific embodiments of the present invention, the inner side of the arc frame 6 can accommodate the cylinder body on the inner expansion shaft 1 .

[0055] It is easy to understand that in this embodiment, the internal space of the arc frame 6 can accommodate the cylinder body, so that the spraying device is further compact, the distance between the spray gun 5 and the cylinder body is shortened, the spraying force is guaranteed, the scattering of paint is reduced, the spraying quality is guaranteed, and at the same time, waste is reduced.

[0056] In some specific embodiments of the present invention, the translation assembly 3 can be located below the inner expansion shaft 1 .

[0057] It is easy to understand that, in this embodiment, by arranging the translation assembly 3 below the inner expansion shaft 1, the spraying requirement is met without affecting the disassembly and assembly of the cylinder body, and space is reserved for arranging the equipment for eliminating exhaust gas.

[0058] In some specific embodiments of the present invention, a material blocking plate 8 may be provided between the inner expansion shaft 1 and the translation assembly 3 .

[0059] It is easy to understand that, by providing the baffle plate 8 in this embodiment, the paint falling on the translation assembly 3 can be reduced, the translation assembly 3 can be kept clean, and the paint can be prevented from adhering to the guide rail of the translation assembly 3 and increasing wear.

[0060] In some specific embodiments of the present invention, a material collecting trough 9 may be provided on the top of the material blocking plate 8 .

[0061] It is easy to understand that, in this embodiment, by providing the collecting trough 9, it is also convenient to collect the paint and avoid the overflow of the paint.

[0062] In some specific embodiments of the present invention, a discharge pipe 10 may be provided at one corner of the collecting trough 9 .

[0063] It is easy to understand that, by providing the discharge pipe 10, this embodiment also facilitates the collection of paint, avoids stopping the machine to clean the collection tank 9, and reduces the impact on production.

[0064] In some specific embodiments of the present invention, the arc frame 6 can accommodate the edge of the material blocking plate 8 to reduce the risk of touching the material blocking plate 8.

[0065] In some specific embodiments of the present invention, the spraying device may further include a water spraying and exhausting box 11 located on one horizontal radial side of the inner expansion shaft 1 .

[0066] It is easy to understand that, by providing the water spraying exhaust box 11, this embodiment also facilitates the spraying of air polluted by spraying, and further, utilizes the spraying water to settle the paint vapor in the air, which helps to protect the environment.
