[0002] As a key protective component of the engine compartment, the side cover of an automobile engine is mainly made of lightweight alloy materials such as aluminum alloy and magnesium alloy or high-strength steel. Its surface quality and performance directly affect the engine's heat dissipation efficiency, corrosion resistance and overall sealing performance. In the processing, the sandblasting machine is the core equipment for the pretreatment of the side cover surface. It removes burrs, oxide scale, oil stains and other residual impurities from the workpiece surface by high-speed spraying of sand particles. At the same time, it can roughen the surface to enhance the adhesion of subsequent coatings such as spraying and electroplating.

[0003] Existing sandblasting machines are not convenient for collecting and treating the generated dust. Dust easily accumulates on the surface of the sandblasting machine cavity, nozzle, pipes and other components, causing wear on mechanical parts. Moreover, the sandblasting angle adjustment of existing sandblasting machines is not flexible enough, and it is difficult to guarantee the uniformity of sandblasting on the workpiece surface. Utility Model Content

[0004] The purpose of this utility model is to provide a sandblasting machine for processing automotive engine side covers. Through the cooperation of air ducts, fans, sandblasting components and turntables, residual dust or sand particles on the surface of the workpiece are blown away and blown into the dust collection box, which avoids dust accumulation on the surface of the sandblasting machine cavity, nozzles, pipes and other components, reduces the wear of mechanical parts by dust, and reduces equipment jamming or failure caused by dust accumulation.

[0011] This utility model has the following beneficial effects:

[0012] This invention utilizes a combination of air ducts, a fan, a sandblasting assembly, and a turntable to blow away residual dust or sand particles from the workpiece surface into a dust collection box. This prevents dust from accumulating on the surfaces of the sandblasting machine cavity, nozzles, pipes, and other components, reducing wear on mechanical parts and minimizing equipment jamming or malfunctions caused by dust accumulation. In the sandblasting assembly, the second driver drives the turntable to rotate, causing the workpiece to rotate. The first driver drives the rotating rod to adjust the nozzle sandblasting angle, adapting to the sandblasting requirements of the complex curved surface of the engine side cover. This ensures that all areas of the workpiece surface receive uniform sandblasting treatment, improving processing quality and precision.

[0020] Please see Figure 1-4This utility model provides a technical solution: a sandblasting machine for processing automotive engine side covers, including a protective cover 1. The protective cover 1 is box-shaped with one side opening. A protective door is hinged to one side opening of the protective cover 1 to facilitate the loading and unloading of workpieces and equipment maintenance. An observation window is provided on the other side of the protective cover 1 to allow operators to monitor the sandblasting operation in real time. Support legs are fixedly connected to the four corners of the bottom surface of the protective cover 1. The bottom end of the protective cover 1 is connected to a dust collection hopper 2 for collecting dust generated during the sandblasting process and facilitating centralized unloading. A dust collection opening is provided at the bottom end of the protective cover 1, and the top of the dust collection hopper 2 is connected to the dust collection opening. A discharge pipe is provided at the bottom end of the dust collection hopper 2 for unloading. A valve is installed on the pipe, and a filter screen 3 is installed inside the protective cover 1 to initially filter and separate the falling dust. The top of the protective cover 1 is connected to the air duct 4, and a fan 5 is installed at one end of the air duct 4. A through hole is opened at the top of the protective cover 1, and one end of the air duct 4 is connected to the through hole. One side of the fan 5 is connected to the support leg by bolts. The fan 5 blows air into the protective cover 1, blowing the dust into the dust collection hopper 2. A sandblasting assembly 6 is installed on one side of the inner wall of the protective cover 1. The sandblasting assembly 6 includes a frame 601. A first driver 602 is installed on one side of the top of the frame 601. One end of the first driver 602 is rotatably connected to a rotating rod 603. A nozzle 604 is installed on the rotating rod 603. A support rod extends from one side of the frame 601, with a turntable 7 rotatably connected to the top of the support rod. A second driver 8 is installed at the bottom of the turntable 7, which drives the turntable 7 to rotate, thus supporting the workpiece and rotating it during the sandblasting process. This ensures that all areas of the side cover surface are uniformly sandblasted, improving processing quality. The two ends of the frame 601 are welded between the opposite side walls of the protective cover 1. The frame 601 is located above the filter screen 3. Two "L"-shaped plates are fixedly connected to both sides of the frame 601. Mounting holes are opened on one side of the top of the two "L"-shaped plates. The two ends of the rotating rod 603 are rotatably connected to the mounting holes. An annular seat is provided at the top of the nozzle 604. 603 passes through the annular seat and connects to the nozzle 604. The first driver 602 can drive the rotating rod 603 to rotate to adjust the sandblasting angle of the nozzle 604, adapting to the sandblasting requirements of the complex curved surface of the engine side cover. The nozzle 604 is externally connected to a shot supply system to provide shot to the nozzle 604, ensuring a continuous shot supply during the shot blasting process.
