Description

Technical Field

[0001] This utility model relates to the field of CNC sandblasting machine technology, specifically a CNC automatic sandblasting machine. Background Technology

[0002] CNC sandblasting machines use compressed air as power to propel abrasive particles at high speed onto the surface of a workpiece through a spray gun. Under the impact and cutting action of the abrasive, dirt, scale, rust, old coatings, and other impurities on the workpiece surface are removed. Simultaneously, the surface roughness of the workpiece can be altered, providing a good base for subsequent surface treatment processes such as coating and electroplating.

[0003] However, existing CNC automatic sanding machines do not have clamping devices, so they cannot fix the workpiece during the sandblasting process. The workpiece is easy to move during the sandblasting process, which affects the sandblasting effect. At the same time, the position of the sandblasting head of the existing sanding machine is fixed and the height of the nozzle cannot be adjusted according to the height of the workpiece, which makes it difficult to achieve precise sandblasting of the workpiece. Utility Model Content

[0007] According to the aforementioned CNC automatic sandblasting machine, a door is rotatably connected to the front of the sandblasting box, and an observation window is provided on the front of the door to facilitate observation of the sandblasting status of the workpiece inside the sandblasting box.

[0008] According to the aforementioned CNC automatic sandblasting machine, the number of slides is three, and the three slides are arranged in a circular array on the top of the turntable to facilitate the movement of the slider and to facilitate precise clamping of the workpiece.

[0009] According to the aforementioned CNC automatic sandblasting machine, a limiting hole is provided on the side of the slider.

By driving the screw 11 to rotate via the servo motor 9, the slider 13 and the clamping column 14 can be moved, thereby clamping the workpiece, improving the stability of the workpiece sandblasting process, and improving the sandblasting effect on the workpiece;

[0025] The top of the sandblasting box 3 is provided with a conveying pipe 17. The top end of the conveying pipe 17 is connected to the sand storage box 18. The bottom end of the conveying pipe 17 passes through the top of the sandblasting box 3 and is connected to the top end of the telescopic pipe 20. The bottom end of the telescopic pipe 20 is provided with a sandblasting head 22. The top of the sandblasting box 3 is fixedly connected with a hydraulic rod 19. The output end of the hydraulic rod 19 is fixedly connected with a lifting plate 21, which facilitates the adjustment of the height of the sandblasting head 22, thereby facilitating the precise sandblasting of the workpiece and improving the sandblasting effect of the workpiece.

[0026] The sandblasting box 3 is rotatably connected to a door 4 on its front. An observation window 5 is provided on the front of the door 4 for easy observation of the sandblasting process of the workpiece inside the sandblasting box 3. Three sliding grooves 8 are arranged in a circular array on the top of the turntable 7, facilitating the movement of the slider 13 and the clamping column 14, thereby facilitating the clamping of the workpiece. Limiting holes 15 are provided on the side of the slider 13. The shape and size of the limiting holes 15 match the shape and size of the limiting rod 10. The slider 13 is slidably connected to the limiting rod 10 through the limiting holes 15, and the limiting rod 10 limits the movement of the slider 13, improving the efficiency of its movement. To ensure the stability of the process, a threaded hole 16 is provided at the center of the side of the slider 13.
