Description

Technical Field

[0001] The present application relates to the technical field of aluminum alloy spraying, and in particular to an automatic spraying device for an aluminum alloy casting barrel. Background Art

[0002] Aluminum alloy casting cylinder is a cylindrical component made of aluminum alloy material through casting process. Aluminum alloy casting has good durability and corrosion resistance. Aluminum itself has stable chemical properties and is not prone to corrosion and rust. In addition, aluminum castings are usually specially treated on the surface, such as spraying electrostatic powder and fluorocarbon coating to enhance its corrosion resistance and keep it from fading for a long time. The existing spraying method generally adopts manual spraying, which is not only inconvenient to operate, but also difficult to control the uniformity of spraying, thus affecting the overall spraying effect.

[0003] Application No. 202221380894.8 discloses an automated spraying device for aluminum alloy profiles, including a spraying area, a drying area, a circulating conveying mechanism, and a mobile spraying mechanism, etc. By cooperating with the circulating conveying mechanism and the clamping and flipping mechanism, it is possible to dry part of the aluminum alloy profiles while spraying the aluminum alloy profiles, thereby effectively improving the spraying efficiency of the aluminum alloy profiles. By cooperating with the clamping and flipping mechanism and the mobile spraying mechanism, the surface of the aluminum alloy profile can be evenly sprayed, thereby effectively ensuring the spraying effect of the aluminum alloy profiles.

[0004] However, in use, there are the following defects:

[0005] Although a circulating conveying structure is used to convey the aluminum alloy parts for cyclic spraying, spraying can only be performed on the outside, and the spraying mechanism cannot cover the side of the casting that contacts the fixed base. At the same time, for cylindrical castings, the inside still cannot be sprayed, so the practicality is low. Utility Model Content

[0006] The purpose of the present application is to provide an automatic spraying device for aluminum alloy casting cylinders, which solves the problem proposed in the background technology that although a circulating conveying structure is used to convey the aluminum alloy parts for cyclic spraying, spraying can only be performed on the outside, and the spraying mechanism cannot cover the side of the casting that contacts the fixed base. At the same time, for the cylindrical casting, the inside still cannot be sprayed, thereby solving the problem of low practicality.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an automatic spraying device for an aluminum alloy casting cylinder, comprising a base, a delivery pipe, a support frame, a strip groove and a driving motor, a center plate is fixedly installed at the center of the top of the base, a central groove is penetrated in the center of the side wall of the center plate, and a storage box is fixedly installed at the top of the base on one side of the center plate, the top of the storage box is movably connected and connected with the delivery pipe, the other end of the delivery pipe penetrates downward from the center of the top of the center plate and is connected with an annular pipe, the annular pipe is located at the inner center of the center groove, a branch pipe is fixedly installed on the side wall of the center plate above the center groove, one end of the branch pipe is connected with the delivery pipe, and the other end of the branch pipe is movably connected with the inner nozzle, and distribution boxes are fixedly installed on both sides of the left and right sides of the top of the base.

[0008] In this technical solution, the electric push rods, fixed plates and clamping blocks on the left and right sides can avoid blocking the surface of the casting. The fixed plates on both sides are respectively set to be horizontal and vertical. The casting is first placed between the two clamping blocks of the vertical fixed block, and then the driving motor is powered on to drive the bidirectional lead screw to rotate, so that the clamping block moves toward the center, thereby clamping the casting. Driven by the extension of the electric push rod after it is powered on, the casting slowly passes through the center groove to receive spraying. At the same time, the fixed plate on the other side is driven by the electric push rod to gradually move closer. When the clamping block reaches the left and right sides, the driving motor drives the lead screw to rotate, so that the clamping block clamps the casting from both sides. At this time, the clamping block of the vertical fixed plate can release the casting, exposing the clamping position to receive spraying, avoiding dead angles and improving the spraying efficiency of the device. At the same time, the inside and outside of the casting barrel can be sprayed at the same time through the branch pipe, the inner nozzle and the outer nozzle. When the casting passes through the central groove, the annular pipe receives the paint from the storage box through the delivery pipe and sprays it from the outer nozzle to spray the central casting. At this time, the inner nozzle and the lower half of the branch pipe will enter the inner side of the casting barrel, and the inner nozzle can perform circumferential spraying on the inside, thereby completing the inside and outside spraying at the same time, improving the spraying efficiency and practicality of the device.

[0009] As an optional solution of the technical solution of the present application, an electric push rod is fixedly installed on one side of the distribution box facing the center plate, and the other end of the electric push rod is fixedly connected to a fixed block, and a side wall of the fixed block is provided with a strip groove.

[0010] As an optional solution of the technical solution of the present application, a bidirectional screw rod is movably installed on the inner side of the strip groove, and clamping blocks are threadedly connected on both sides of the surface of the bidirectional screw rod.

[0011] As an optional solution of the technical solution of the present application, the branch pipe is located above the fixed plate on one side of the center plate, and the fixed block under the branch pipe is arranged horizontally, and the fixed block on the other side is arranged vertically.

[0012] As an optional solution of the technical solution of the present application, a plurality of outer nozzles are evenly arranged on the inner circle of the annular tube.

[0013] As an optional solution of the technical solution of the present application, a driving motor is fixedly installed on the outer side wall of the fixed plate facing one end of the bidirectional screw, and the rear end of the transmission shaft of the driving motor is fixedly connected to the bidirectional screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can avoid blocking the surface of the casting by the electric push rods, fixed plates and clamping blocks on the left and right sides. The fixed plates on both sides are respectively arranged in the horizontal and vertical directions. The casting is first placed between the two clamping blocks of the vertical fixed block, and then the driving motor is powered on to drive the bidirectional screw rod to rotate, so that the clamping block moves toward the center, thereby clamping the casting. Driven by the extension of the electric push rod after being powered on, the casting slowly passes through the center groove to receive spraying. At the same time, the fixed plate on the other side gradually moves closer under the drive of the electric push rod. When the clamping blocks reach the left and right sides gradually, the driving motor drives the screw rod to rotate, so that the clamping blocks clamp the casting from both sides. At this time, the clamping blocks of the vertical fixed plates can release the casting, exposing the clamping position to receive spraying, avoiding dead angles and improving the spraying efficiency of the device.

[0016] 3. The present application can spray the inside and outside of the casting barrel at the same time through the branch pipe, the inner nozzle and the outer nozzle. When the casting passes through the central groove, the annular tube receives the coating from the storage box through the delivery pipe and sprays it from the outer nozzle to spray the central casting. At this time, the inner nozzle and the lower half of the branch pipe will enter the inner side of the casting barrel, and the inner nozzle can perform annular spraying on the inner side, thereby completing the internal and external spraying at the same time, improving the spraying efficiency and practicality of the device.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, they are further explained below in conjunction with specific implementation methods.

[0023] like Figure 1 As shown, an automatic spraying device for aluminum alloy casting cylinder includes a base 1, a conveying pipe 5, a support frame 8, a strip groove 12 and a driving motor 14. A center plate 2 is fixedly installed at the center of the top of the base 1, and a penetrating center groove 3 is opened in the center of the side wall of the center plate 2.

[0024] like Figure 1 As shown, a distribution box 9 is fixedly installed on both sides of the top of the base 1, and an electric push rod 10 is fixedly installed on the side of the distribution box 9 facing the center plate 2. The other end of the electric push rod 10 is fixedly connected to a fixed block 11, and a strip groove 12 is opened on the side wall of the fixed block 11.

[0025] like Figure 2 As shown, a storage box 4 is fixedly installed on the top of the base 1 on one side of the center plate 2, and the top of the storage box is movably connected and connected to a delivery pipe 5. The other end of the delivery pipe 5 passes downward from the center of the top of the center plate 2 and is connected to an annular tube 6. The annular tube 6 is located at the inner center of the center groove 3. The inner circle of the annular tube 6 is evenly provided with a plurality of outer nozzles 601. The outer nozzles 601 are evenly provided, and can spray the casting cylinder passing through the center from all directions.

[0026] like Figure 2 As shown, a branch pipe 7 is fixedly installed on the side wall of the center plate 2 above the center groove 3. One end of the branch pipe 7 is connected to the delivery pipe 5, and the other end of the branch pipe 7 is movably connected to the inner nozzle 701. The branch pipe 7 is in a "J" shape, which is convenient for extending into the inner side of the casting tube for spraying.

[0027] like Figure 2 As shown, the branch pipe 7 is located above the fixed plate on one side of the center plate 2, and the fixed block 11 below the branch pipe 7 is arranged horizontally, and the fixed block 11 on the other side is arranged vertically, which can avoid blocking the branch pipe 7.

[0028] like Figure 3 As shown, a bidirectional screw rod 121 is movably installed inside the strip groove 12 , and clamping blocks 13 are threadedly connected to both sides of the surface of the bidirectional screw rod 121 .

[0029] like Figure 3 As shown, the driving motor 14 is fixedly mounted on the outer side wall of the fixing plate toward which one end of the bidirectional screw rod 121 faces, and the rear end of the transmission shaft of the driving motor 14 is fixedly connected to the bidirectional screw rod 121 .

[0030] In actual use, the electric push rods 10, the fixing plates and the clamping blocks 13 on the left and right sides can avoid blocking the surface of the casting. The fixing plates on both sides are respectively arranged in the horizontal and vertical directions. The casting is first placed between the two clamping blocks 13 of the vertical fixing block 11, and then the driving motor 14 is powered on to drive the bidirectional screw rod 121 to rotate, so that the clamping block 13 moves toward the center, thereby clamping the casting. Driven by the extension of the electric push rod 10 after it is powered on, the casting slowly passes through the central groove 3 to receive the spraying. At the same time, the fixing plate on the other side is driven by the electric push rod 10 to gradually move closer. When the clamping block 13 reaches the left and right sides, the driving motor 14 drives the screw rod to rotate, so that the clamping block 13 clamps the casting from both sides. At this time, the clamping block 13 of the vertical fixed plate can release the casting, exposing the clamping position to receive spraying, avoiding dead angles, and improving the spraying efficiency of the device. At the same time, through the branch pipe 7, the inner nozzle 701 and the outer nozzle 601, the inner and outer sides of the casting tube can be sprayed at the same time. When the casting passes through the central groove 3, the annular tube 6 receives the paint from the storage box 4 through the delivery pipe 5 and sprays it from the outer nozzle 601 to spray the central casting. At this time, the inner nozzle 701 and the lower half of the branch pipe 7 will enter the inner side of the casting tube, and the inner nozzle 701 can perform circumferential spraying on the inner side, thereby completing the inside and outside spraying at the same time, improving the spraying efficiency and practicality of the device.
