Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a surface coating apparatus for metal part processing. (Refer to...) Figure 1-4A surface coating device for metal parts processing includes a coating box 1, with a door 4 hinged to the open end of the coating box 1. A placement plate 2 is rotatably mounted inside the coating box 1, and a coating assembly 3 is mounted on the coating box 1. The coating assembly 3 includes a threaded rod 32 rotatably mounted inside the coating box 1, a mounting base 33 threadedly connected to the outer side of the threaded rod 32, a hydraulic cylinder 34 mounted at the bottom of the mounting base 33, a nozzle 35 mounted at the output end of the hydraulic cylinder 34, and a paint tank 37 mounted on the outer wall of the coating box 1. A booster pump 38 is installed on the top of the spray box 7. The output end of the booster pump 38 is connected to the nozzle 35 through a hose. A smooth rod 31 is installed inside the spray box 1. The mounting base 33 is slidably sleeved on the outside of the smooth rod 31. An exhaust fan 6 is installed on the top wall of the spray box 1. A dust filter cover 5 is detachably installed on the top of the spray box 1 outside the exhaust fan 6. Two layers of activated carbon filter plates 51 are inserted inside the dust filter cover 5. Pins for restricting the movement of the activated carbon filter plates 51 are inserted on the side wall of the dust filter cover 5.

[0022] Here, the metal parts are placed on the placement plate 2, then the box door 4 is closed, and the exhaust fan 6, hydraulic cylinder 34, drive motor 36, and booster pump 38 are started. The booster pump 38 can extract the spray from inside the paint box 37 and spray it out through the nozzle 35 to achieve the spraying operation. The drive motor 36 can drive the threaded rod 32 to rotate, and the threaded rod 32 can push the mounting base 33 to move the hydraulic cylinder 34 and the nozzle 35 to increase the spraying range. At the same time, the hydraulic cylinder 34 can push the nozzle 35 to move up and down, increasing the spraying height of the nozzle 35. Secondly, the exhaust fan 6 can extract the gas inside the spray box 1, filter it through the activated carbon filter plate 51, and then discharge it, so that the harmful gases generated during the spraying of metal parts can be adsorbed and purified to avoid harming the health of the workers.

[0023] Reference Figure 2 and Figure 4 A support platform 11 is installed on the inner wall of the bottom end of the spray box 1. A rotating shaft 25 is rotatably arranged in the middle of the support platform 11 and fixedly connected to the placement plate 2. A rotary motor 12 for driving the rotating shaft 25 to rotate is fixedly installed on the bottom wall of the spray box 1. A ball bearing 26 groove 111 is opened on the top wall of the support platform 11. A ball bearing 26 that cooperates with the ball bearing 26 groove 111 is rotatably arranged at the bottom of the placement plate 2.

[0024] Here, by starting the rotary motor 12, the rotary motor 12 can drive the rotating shaft 25 to rotate, and the rotating shaft 25 can drive the placement plate 2 to rotate, so that the metal parts can be fully sprayed; and by opening the ball bearing 26 groove 111 on the support table 11 and setting the ball bearing 26 in conjunction, the friction between the placement plate 2 and the support table 11 can be reduced.

[0025] Reference Figure 4The top of the placement plate 2 is symmetrically provided with sliding grooves 21. The same bidirectional lead screw 22 is rotatably arranged inside the two sliding grooves 21. The outer side of the bidirectional lead screw 22 is threadedly connected to a slider 23. The top of the slider 23 is fixedly installed with a clamping plate 24. One end of the bidirectional lead screw 22 passes through the side wall of the placement plate 2 and is fixedly connected to a turntable.

[0026] Here, by rotating the turntable, the turntable drives the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 can push the two sliders 23 closer to each other, so that the clamping plate 24 can fix and hold the metal part, improving the stability of the metal part during spraying.

[0027] Reference Figure 2 A drive motor 36 is fixedly installed on the outer wall of the spray box 1, and the output shaft of the drive motor 36 is fixedly connected to the threaded rod 32.

[0028] Here, by starting the drive motor 36, the drive motor 36 can drive the threaded rod 32 to rotate.

[0029] Reference Figure 1 An observation window 41 is provided on the upper side of the door 4, and multiple filter holes 42 are provided on the lower side of the door 4.

[0030] The observation window 41 allows for a direct observation of the coating condition of the metal parts.

[0031] The implementation principle of the surface spraying device for metal parts processing in this application embodiment is as follows: During use, the device is placed in a designated position and the power is turned on. Then, the metal part to be sprayed is placed on the placement plate 2. The turntable is then rotated, causing the bidirectional lead screw 22 to rotate. The bidirectional lead screw 22 pushes two sliders 23, causing the clamping plates 24 to move closer together, thus securing the metal part. Then, the rotary motor 12, exhaust fan 6, hydraulic cylinder 34, drive motor 36, and booster pump 38 are activated. The booster pump 38 extracts the spray from inside the paint tank 37 and sprays it out through the nozzle 35 to achieve the spraying operation. The rotary motor... Machine 12 can drive the rotating shaft 25 to rotate, and the rotating shaft 25 can drive the placement plate 2 and metal parts to rotate. The drive motor 36 can drive the threaded rod 32 to rotate, and the threaded rod 32 can push the mounting base 33 to move the hydraulic cylinder 34 and the spray head 35 to increase the spraying range. At the same time, the hydraulic cylinder 34 can push the spray head 35 to move up and down, increasing the spraying height of the spray head 35. Secondly, the exhaust fan 6 can extract the gas inside the spray box 1, filter it through the activated carbon filter plate 51, and then discharge it, so that the harmful gases generated during the spraying of metal parts can be adsorbed and purified to avoid harming the health of the workers.
