DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a painting device for machining mechanical parts with a cooling structure, comprising a workbench 1, a first bracket 3 and a second bracket 4 are connected to the workbench 1, a spraying assembly 5 is connected to the first bracket 3, a cold air assembly 6 is connected to the second bracket 4, the cold air assembly 6 is connected to two cooling air outlet plates 7 through a connecting pipe, the two cooling air outlet plates 7 are respectively arranged in the second bracket 4 and under the workbench 1, two bearing plates 11 are connected to the workbench 1, one of the bearing plates 11 is provided with a moving frame 12, two sliding limit grooves 15 are provided in the moving frame 12, a moving limit device 14 is provided in the sliding limit groove 15, an extrusion rod 10 is overlapped on the side of the moving limit device 14, and the two extrusion rods 10 are connected to a guide hole plate 9 arranged on the workbench 1 on the side away from each other;

[0022] A spraying assembly 5 is used to spray paint on parts, and a cold air assembly 6 and a cooling air outlet plate 7 are used. The cold air assembly 6 sucks gas and cools it down, and at the same time passes the low-temperature gas into the cooling air outlet plate 7. The two cooling air outlet plates 7 blow the low-temperature gas on the upper and lower sides of the parts;

[0023] The movable limiting device 14 includes a slide plate 141, and a movable clamping plate 142 is connected to the side of the slide plate 141 away from the guide hole plate 9. The movable clamping plate 142 is slidably arranged in the movable frame 12. The side of the slide plate 141 close to the guide hole plate 9 is connected to a movable rod 143, and the movable rod 143 is overlapped on the side of the extrusion rod 10.

[0024] The movable clamping plate 142 cooperates with the movable frame 12, and the movable clamping plate 142 clamps the parts in the movable frame 12, so that the parts can be loaded and unloaded along with the movable frame 12, and the upper and lower sides of the parts are exposed;

[0025] Four supporting legs 2 are connected to the workbench 1 . A connecting hole 8 is provided under the workbench 1 . Two bearing plates 11 are respectively located on both sides of the connecting hole 8 .

[0026] The connection hole 8 is used to facilitate the cooling air outlet plate 7 on the lower side to blow out low-temperature gas to act on the lower side of the parts;

[0027] The position of the cooling air outlet plate 7 corresponds to the position of the connecting hole 8, and both ends of the extrusion rod 10 are set as inclined surfaces.

[0028] The extrusion rod 10 cooperates with the moving rod 143, and when the moving frame 12 and the bearing plate 11 are in corresponding positions, the extrusion rod 10 and the moving rod 143 are separated. As the moving frame 12 moves, the extrusion rod 10 will squeeze the moving rod 143 and the moving clamping plate 142 to automatically move, thereby achieving the clamping limit of the parts;

[0029] The slide plate 141 is slidably disposed in the slide limiting groove 15 . The slide limiting groove 15 is configured to be rectangular, and the moving rod 143 is configured to be cylindrical.

[0030] The sliding limit groove 15 and the slide plate 141 are used, and the sliding limit groove 15 limits the slide plate 141 to prevent the slide plate 141 and the moving rod 143 from rotating;

[0031] A guide sleeve 144 is provided on the outer sleeve of the moving rod 143 . The guide sleeve 144 penetrates the sliding limit groove 15 . An elastic component 145 is provided on the outer sleeve of the moving rod 143 . Two ends of the elastic component 145 are respectively connected to the guide sleeve 144 and the slide plate 141 .

[0032] The guide sleeve 144 is used to limit the moving rod 143 so that the moving rod 143 can stably move in a straight line. The elastic component 145 controls the moving clamping plate 142 to automatically separate from the parts after the moving rod 143 is separated from the extrusion rod 10.

[0033] Both the front and rear sides of the moving frame 12 are provided with driving wheels 13 , and the driving wheels 13 are arranged in the guide hole plate 9 .

[0034] The driving wheel 13 cooperates with the guide hole plate 9 to control the moving frame 12 to move in the horizontal direction.

[0035] The working principle of the utility model is:

[0036] When it is necessary to spray paint the parts, the parts are directly placed in the moving frame 12, and then the driving wheel 13 is controlled to work. When the driving wheel 13 rotates, it moves in the guide hole plate 9. At this time, the moving frame 12 moves away from one side of the bearing plate 11, and at the same time, the extrusion rod 10 squeezes the moving moving rod 143. The moving rod 143 controls the moving clamping plate 142 to move away from the guide hole plate 9 through the slide plate 141. The two moving clamping plates 142 push the parts to the middle position of the moving frame 12 and clamp them to limit the position. When the parts move to the corresponding spraying position, After the component 5 is positioned, the spray component 5 works to spray paint the parts. When the painting operation is completed and the parts are moved to the position corresponding to the cooling air outlet plate 7, the cold air component 6 works to spray the low-temperature gas through the two cooling air outlet plates 7 on the upper and lower sides of the parts respectively. The parts are quickly dried after spraying. When the parts move to the upper side of another supporting plate 11 and the moving rod 143 is separated from the extrusion rod 10, the elastic component 145 drives the moving rod 143 and the moving clamp 142 to separate from the parts. At this time, the cooled parts can be removed.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0038] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
