Description

Technical Field

[0001] This invention relates to the technical field of spraying devices, and more specifically to an automatic spraying device for machining. Background Technology

[0002] In the field of machining, spraying the surface of workpieces is a common process, aimed at improving their rust resistance, aesthetics, and service life. However, many spraying devices currently on the market have numerous shortcomings: Traditional clamping mechanisms have low adaptability to workpieces of different sizes and shapes, and workpiece misalignment is prone to occur during clamping, resulting in inaccurate spraying positions and affecting spraying quality. Moreover, during the spraying process, excess paint often drips directly onto the worktable, which cannot be recycled, causing a large amount of paint waste, and requires manual cleaning of the worktable afterward, increasing labor intensity. At the same time, the dripping paint may also pollute the working environment. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic spraying device for machining, so as to overcome the above-mentioned defects in the prior art.

[0004] An automatic spraying device for machining includes a worktable, a clamping mechanism, a spraying mechanism, and a scraping mechanism. The clamping mechanism is mounted on the worktable and is used to clamp and fix the workpiece. The spraying mechanism is mounted on the workbench and located to the side of the clamping mechanism and is used to spray paint on the surface of the workpiece. The scraping mechanism is located below the clamping mechanism to collect and process excess paint.

[0005] Preferably, the clamping mechanism includes a fixed plate, guide rods, springs, and clamping plates. The fixed plate is rotatably connected to the worktable via a rotating shaft. The fixed plate has a mounting groove in the middle. Guide rods are slidably connected to both ends of the mounting groove. Each guide rod has a baffle plate at its outer end and a movable block that is slidably connected to the mounting groove at its inner end. A spring is sleeved on each guide rod between the movable block and the inner wall of the mounting groove. A clamping plate is provided on the top of each movable block.

[0006] Preferably, the spraying mechanism includes a fixed frame, a drive screw, a lifting motor, a lifting plate, and a spray head. The fixed frame is vertically mounted on the worktable. The two ends of the drive screw are rotatably connected to the slide grooves on the fixed frame. The lifting motor is mounted on the top of the fixed frame and its output shaft is connected to the drive screw. The lifting plate is screwed to the drive screw through a screw nut. The spray head is vertically mounted on the lifting plate and connected to the paint pump through a pipe.

[0007] Preferably, the scraping mechanism includes a baffle, a scraper, and a drive motor. The baffle is disposed on the worktable and located below the fixed plate. A feeding pipe is provided on the side of the baffle. The scraper is disposed on the side of the rotating shaft. The drive motor is installed at the bottom of the worktable and its output shaft is connected to the rotating shaft.

[0008] Preferably, the clamping plate has an arc-shaped structure.

[0009] Preferably, the bottom of the clamping plate is threadedly connected to the threaded post at the top of the moving block.

[0010] Preferably, the fixed disk has symmetrical through holes on both sides.

[0011] Preferably, the baffle is an annular structure and its diameter is larger than that of the fixed disk.

[0012] Preferably, the scraper has an "L" shaped structure.

[0013] The beneficial effects achieved by this invention are as follows: 1. The clamping mechanism of this application adopts a structure of spring and guide rod cooperation. The spring force can automatically adapt to workpieces of different sizes to achieve fast and stable clamping. The clamping plate has an arc structure, which can increase the contact area with the workpiece and further improve the clamping stability. At the same time, the clamping plate is connected to the moving block through the threaded column, which makes it easy to replace the clamping plate according to the shape of the workpiece, and has wider adaptability.

[0014] 2. In the scraping mechanism provided in this application, the annular baffle can effectively block the dripping paint from flowing out, and the diameter of the baffle is larger than the diameter of the fixed plate to ensure that there is no paint leakage; the scraper on the rotating shaft can scrape the paint in the baffle to the feed pipe for collection when the shaft rotates, so as to realize the recycling and reuse of paint, reduce paint waste, and reduce production costs; at the same time, it avoids paint dripping onto the workbench, eliminating the need for manual cleaning, reducing labor intensity, and protecting the working environment.

[0025] like Figures 1-6 As shown, the present invention provides an automatic spraying device for machining, including a worktable 1, a clamping mechanism 2, a spraying mechanism 3 and a scraping mechanism 4; In addition, the clamping mechanism 2 is provided on the workbench 1 and is used to clamp and fix the workpiece. The clamping mechanism 2 includes a fixed plate 21, a guide rod 23, a spring 25 and a clamping plate 26. The fixed plate 21 is rotatably connected to the workbench 1 through a rotating shaft 22. The fixed plate 21 has symmetrical through holes 212 on both sides, so that excess paint can flow quickly into the baffle 41. In addition, the fixed plate 21 is provided with a mounting groove 211 in the middle, and guide rods 23 are slidably connected to both ends of the mounting groove 211. Each guide rod 23 is provided with a baffle 231 at its outer end, and a moving block 24 is slidably connected to the mounting groove 211 at its inner end. A spring 25 is sleeved on each guide rod 23 between the moving block 24 and the inner wall of the mounting groove 211. However, each moving block 24 is provided with a clamping plate 26 at the top, the bottom of which is threaded to the threaded post 241 at the top of the moving block 24. The clamping plate 26 has an arc-shaped structure to accommodate the clamping of workpieces of different sizes. The spraying mechanism 3 is mounted on the workbench 1 and located to the side of the clamping mechanism 2, and is used to spray paint on the surface of the workpiece. The spraying mechanism 3 includes a fixed frame 31, a drive screw 32, a lifting motor 33, a lifting plate 34, and a spray nozzle 35. The fixed frame 31 is vertically mounted on the workbench 1. The two ends of the drive screw 32 are rotatably connected to the slide grooves 311 on the fixed frame 31. The lifting motor 33 is mounted on the top of the fixed frame 31, and its output shaft is connected to the drive screw 32. The lifting plate 34 is screwed to the drive screw 32 through a screw nut. The spray nozzle 35 is vertically mounted on the lifting plate 34 and connected to the paint pump through a pipe 36.

[0026] The scraping mechanism 4 is located below the clamping mechanism 2 to collect excess paint. The scraping mechanism 4 includes a baffle 41, a scraper 43 and a drive motor 44. The baffle 41 is located on the workbench 1 and below the fixed disk 21. The baffle 41 has a circular structure and its diameter is larger than that of the fixed disk 21 to prevent excess paint from flowing out. The side of the baffle 41 is provided with a discharge pipe 42, the scraper 43 has an "L" shaped structure and is provided on the side of the rotating shaft 22, the drive motor 44 is installed at the bottom of the workbench 1 and its output shaft is connected to the rotating shaft 22. The drive motor 44 drives the paint in the baffle 41 to be scraped out into the discharge pipe 42. Detailed implementation methods and principles: During operation, the workpiece to be sprayed is first placed between the two clamping plates 26 of the clamping mechanism 2, and the workpiece is clamped and fixed under the elastic force of the spring 25 on the guide rod 23. Then start the lifting motor 33. The output shaft of the lifting motor 33 drives the drive screw 32 to rotate, thereby moving the nozzle 35 on the lifting plate 34 on the fixed frame 31. Then start the paint pump to input the paint into the nozzle 35 through the pipe 36. When the drive motor 44 is turned on, the output shaft of the drive motor 44 drives the rotating shaft 22 and the workpiece on the fixed plate 21 to rotate. The paint is sprayed onto the surface of the workpiece through the nozzle 35. At the same time, the excess paint flows into the annular baffle 41 and is collected through the feed pipe 42 by the scraper 43 on the rotating shaft 22.

[0027] Then, the first motor 7 and the spraying mechanism 311 are started. The spraying mechanism 311 moves up and down on the lead screw 8 via the moving block 249 and the synchronous plate 10. By rotating the workpiece and moving the spraying mechanism 311 up and down, the workpiece can be fully sprayed. The above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention.
