[0002] Aluminum alloy parts sandblasting equipment is a special equipment used for surface sandblasting of aluminum alloy parts. Its main purpose is to remove impurities and oxide layers on the surface of aluminum alloy parts, improve surface roughness, and provide a good foundation for subsequent coating, painting or anodizing processes. It uses compressed air as the power, and the negative pressure formed by the high-speed movement of compressed air in the spray gun sucks the abrasive into the spray gun through the sand conveying pipe and sprays it out at high speed through the nozzle. The high-speed sprayed abrasive impacts the surface of the workpiece to achieve the purpose of processing.

The air outlet end of the first pipeline is buried in the sand particles in the holding cavity and is close to the sand outlet. The air source device supplies air to the first pipeline, and gas with a certain air pressure is ejected from the air outlet end of the first pipeline.

[0004] The above-mentioned sandblasting equipment has certain shortcomings when performing aluminum alloy parts processing operations. The spray gun structure of the above-mentioned sandblasting equipment is installed in a fixed position. When performing the sandblasting operation, the aluminum alloy parts are held by the operation port and manually sandblasted. The sandblasting force is affected by the sandblasting distance, and the sandblasting force cannot be accurately controlled during manual operation, resulting in rough and uneven surfaces of the aluminum alloy parts, reducing the processing effect; at the same time, when performing sandblasting of aluminum alloy parts, traditional equipment manually adjusts the position and angle of the aluminum alloy parts, so that the sand body cannot be evenly sprayed on the surface of the aluminum alloy parts, and cannot be flexibly applied to aluminum alloy parts of different widths, reducing its use effect; secondly, when the traditional sandblasting equipment is in use, the sand body rebounds and falls after being sprayed on the surface of the aluminum alloy parts, so that the sand body of the sandblasting can only complete the aluminum alloy parts processing once, reducing its sandblasting efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a sandblasting equipment for aluminum alloy parts, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. The spray gun structure of the above-mentioned sandblasting equipment is installed in a fixed position. When performing the sandblasting operation, the aluminum alloy part is held by the operating port and the aluminum alloy part is manually sandblasted. The sandblasting force is affected by the sandblasting distance, and the sandblasting force cannot be accurately controlled during manual operation, making the surface of the aluminum alloy part rough and uneven, reducing its treatment effect;

[0008] 2. When sandblasting aluminum alloy parts, the traditional equipment manually adjusts the position and angle of the aluminum alloy parts, so that the sand body cannot be evenly sprayed on the surface of the aluminum alloy parts, and it cannot be flexibly applied to aluminum alloy parts of different widths, which reduces its use effect;

[0009] 3. Secondly, when the traditional sandblasting equipment is in use, the sand body is sprayed on the surface of the aluminum alloy part and then rebounds and falls, so that the sand body of the sandblasting can only complete the aluminum alloy part processing once, which reduces its sandblasting efficiency.

[0010] The purpose of the present invention can be achieved by the following technical solutions:

[0011] A sandblasting treatment device for aluminum alloy parts comprises a fixed base and a sealing cover, wherein the sealing cover is fixedly mounted on the upper outer surface of the fixed base, a spray gun is movably mounted inside the sealing cover, a flip fixture for loading aluminum alloy parts is arranged on the upper end of the fixed base, the spray gun and the sealing cover are movably connected via a vertical slide rail and a horizontal slide rail, the vertical slide rail is movably mounted on both ends of the horizontal slide rail, a quadrangular cover is fixedly sleeved on the output end of the spray gun, and the flip fixture comprises a first clamping plate, a second clamping plate and a sliding base plate, the first clamping plate and the second clamping plate are both movably mounted on the upper outer surface of the sliding base plate, the first clamping plate is movably mounted on one side of the second clamping plate, and a rotating chuck is movably mounted on the middle position of the side edges of the first clamping plate and the second clamping plate.

[0012] As a further technical solution of the present invention, the spray gun and the transverse slide are slidably connected via a transverse slide, and the transverse slide and the vertical slide are connected via a vertical slide. Both the transverse slide and the vertical slide are driven by a linear motor. The transverse slide cooperates with the transverse slide to adjust the sandblasting position of the spray gun laterally. Secondly, the vertical slide cooperates with the vertical slide to adjust the sandblasting height of the spray gun up and down. The adjustment of the sandblasting height can control the spraying intensity and range. When the spray gun is lower, the sand body sprayed by the spray gun is more concentrated, the spraying distance is shorter, and the sandblasting intensity is greater. When the spray gun is higher, the sand body sprayed by the spray gun is more diffuse, the spraying distance is longer, and the sandblasting intensity is smaller. The user can adjust the use height of the spray gun according to the type of aluminum alloy parts, thereby controlling the sandblasting intensity and range of the controller.

[0013] As a further technical solution of the present invention, the spray gun and the quadrangular cover are butt-jointed and fixed by a threaded sleeve, the outer surface of the quadrangular cover is a quadrangular pyramid structure, and a filter fan is installed on the upper end of the sealing cover. The filter fan can be used to filter and discharge the dust-containing gas. When the spray gun performs close-range sandblasting on the surface of the aluminum alloy part, the quadrangular cover can effectively improve the sandblasting effect of the spray gun on the aluminum alloy part and reduce the dust phenomenon. When the sand body is sprayed out from the spray gun, the sand body hits the surface of the aluminum alloy part, and the sand body rebounds to the quadrangular cover after the impact. The quadrangular cover is used to rebound the sand body for the second time, so that the sand body repeatedly hits the surface of the aluminum alloy part, thereby realizing the rebound sandblasting treatment of the aluminum alloy part.

[0014] As a further technical solution of the present invention, a mesh plate is provided at the bottom of the sealing cover, a sand collecting hopper is provided at the bottom of the fixed base, and a discharge pipe is fixedly installed at the lower end of the sand collecting hopper. The interior of the discharge pipe is inclined. When the sand body is sprayed out from the spray gun, the sand body is discharged from the interior of the sealing cover through the mesh plate, so that the sand body falls into the sand collecting hopper and is discharged outward through the discharge pipe of the sand collecting hopper.

[0015] As a further technical solution of the present invention, a discharge hopper is fixedly installed in the middle position of the upper end of the sealing cover, and a return box is installed at one end of the discharge pipe. One end of the discharge hopper and the return box are connected by a feeding auger. The feeding auger can be used to transport the sand body discharged from the discharge pipe into the return box upward, and the used sand body is circulated to the inside of the discharge hopper through the feeding auger, and the discharge hopper is used to transport the sand body to the inside of the spray gun through the pipe body.

[0016] As a further technical solution of the present invention, a boosting pipe is fixedly installed on the outer surface of one side of the sealing cover, and an air pump is fixedly installed on the lower end of the boosting pipe. The boosting pipe and the spray gun are connected through a pipe body, and the air pump is used to generate high-pressure gas, and the gas is transported to the spray gun through the boosting pipe and the pipe body. Two sets of connectors are provided at one end of the spray gun, which can be connected to the two sets of pipe body structures respectively. The spray gun is controlled by a solenoid valve. When the solenoid valve of the spray gun is opened, the sand body in the spray gun is sprayed out by high-pressure gas to achieve sandblasting of the aluminum alloy parts.

[0017] As a further technical solution of the present invention, the upper end of the sliding base is provided with a sliding groove used in conjunction with the first clamping plate and the second clamping plate, and the upper end of the sliding base is a hollow structure. The sliding base and the fixed base are slidably connected by a sliding clamping strip. The user clamps the aluminum alloy part between the first clamping plate and the second clamping plate, rotates the aluminum alloy part with a rotating chuck, pushes the flip clamp into the interior of the sealing cover with the sliding clamping strip, closes the sealing cover, and performs rotational sandblasting on the aluminum alloy part.

[0018] As a further technical solution of the present invention, the first clamping plate and the second clamping plate are driven by a first screw rod, and the rotating chuck on one side of the first clamping plate is driven by a motor. The first screw rod is a bidirectional screw rod, so that when the first screw rod rotates, the first clamping plate and the second clamping plate move toward each other, so that the rotating chuck is clamped at both ends of the aluminum alloy part. The rotating chuck is driven by the motor, so that the aluminum alloy part can rotate between the two sets of rotating chucks.

[0019] As a further technical solution of the present invention, four groups of fixed clamping rods are movably installed on one side of the rotating chuck, and the fixed clamping rods and the rotating chuck are slidingly connected through an X-shaped groove. A second screw rod is movably installed on the inner side of the rotating chuck, and the interior of the rotating chuck is a hollow structure. The four groups of fixed clamping rods move synchronously along the X-shaped grooves. The four groups of fixed clamping rods can be used to fix plate-like parts or columnar parts, thereby realizing the fixing operation of different types of aluminum alloy parts.

[0020] As a further technical solution of the present invention, a rotating block is installed at the lower end of the four groups of fixed card rods, and the rotating block is stuck on the inner side of the X-shaped groove. A docking slider is movably installed at the bottom of the rotating block. The outer surface of the docking slider is movably sleeved with a sliding base. The two groups of sliding bases are driven by a second screw rod. During operation, the second screw rod is rotated, and the second screw rod is a bidirectional screw rod, so that the two groups of sliding bases move toward each other. The fixed card rod utilizes the movably docking between the rotating block and the X-shaped groove. When the sliding base moves, the rotating block moves along the X-shaped groove, thereby adjusting the position between the four groups of fixed card rods.

[0021] Beneficial effects of the present invention:

[0022] 1. By setting a horizontal slide and a vertical slide, when the aluminum alloy parts sandblasting equipment is used, it has a movable spray gun adjustment structure, which can flexibly control the sandblasting force and range of the spray gun, thereby improving the use effect of the sandblasting equipment;

[0023] During operation, the user installs the aluminum alloy parts to be processed on the inner side of the flip fixture, pushes the flip fixture into the inside of the sealing cover, uses the air pump to generate high-pressure gas, and transports the gas to the spray gun through the booster pipe and the pipe body. One end of the spray gun is provided with two sets of joints, which can be connected to the two sets of pipe body structures respectively, and the sand body is transported to the spray gun through the discharge hopper and the pipe body. The spray gun is controlled by the electromagnetic valve. When the electromagnetic valve of the spray gun is opened, the sand body in the spray gun is sprayed out by the high-pressure gas to realize the sandblasting treatment of the aluminum alloy parts. The sandblasting position of the spray gun can be adjusted horizontally by using the horizontal slide seat and the horizontal slide rail. Secondly, the vertical slide seat and the vertical slide rail can adjust the sandblasting height of the spray gun up and down. The adjustment can control the spraying intensity and range. When the spray gun is lower, the sand sprayed by the spray gun is more concentrated, the spraying distance is shorter, and the sandblasting intensity is greater. When the spray gun is higher, the sand sprayed by the spray gun is more diffuse, the spraying distance is longer, and the sandblasting intensity is smaller. The user can adjust the use height of the spray gun according to the type of aluminum alloy parts, thereby controlling the sandblasting intensity and range of the controller, and adjust the sandblasting position with the horizontal slide. Secondly, the feeding auger can be used to transport the sand discharged into the return box through the discharge pipe upward, and the used sand body is circulated to the inside of the discharge hopper through the feeding auger, and the discharge hopper is used to transport the sand body to the inside of the spray gun through the pipe body to complete the recycling of the sand body.

[0024] 2. By setting a flip fixture, when the aluminum alloy parts sandblasting equipment is used, the use of the horizontal slide and the vertical slide is optimized, so that the aluminum alloy parts can be flipped and moved to improve the sandblasting effect;

[0025] During use, the user clamps the aluminum alloy part between the first clamping plate and the second clamping plate, and the first screw rod is a bidirectional screw rod, so that when the first screw rod rotates, the first clamping plate and the second clamping plate move toward each other, so that the rotating chuck is clamped at the two ends of the aluminum alloy part, and the rotating chuck is driven by a motor so that the aluminum alloy part can be rotated between the two sets of rotating chucks. The rotating chuck is used to rotate the aluminum alloy part, and the bottom of the sliding clamp is driven by an electric caster. The sliding clamp is used to push the flip clamp into the interior of the sealing cover, and the sealing cover is closed to perform rotational sandblasting on the aluminum alloy part. Secondly, the sliding clamp can be used to adjust its position during sandblasting of the aluminum alloy part, and the horizontal slide seat is used to adjust the position of the spray gun to complete the overall sandblasting of the aluminum alloy part. It is suitable for sandblasting of plate-like parts, and the rotation adjustment of the aluminum alloy part by the rotating chuck can be suitable for sandblasting of columnar parts.

[0026] 3. By setting a quadrangular cover and a fixed clamping rod, when the aluminum alloy parts sandblasting equipment is used, the use of a vertical slide seat can improve the sandblasting effect of the aluminum alloy parts, and at the same time, it can be flexibly applied to different types of aluminum alloy parts;

[0027] During operation, the vertical slide is used to adjust the position of the spray gun. When the spray gun performs close-range sandblasting on the surface of the aluminum alloy part, the installation of a quadrangular cover can effectively improve the sandblasting effect of the spray gun on the aluminum alloy part, while reducing the dust phenomenon. When the sand body is ejected from the spray gun, the sand body hits the surface of the aluminum alloy part, and the sand body rebounds to the quadrangular cover after the impact. The quadrangular cover is used to rebound the sand body for a second time, so that the sand body repeatedly hits the surface of the aluminum alloy part, thereby achieving rebound sandblasting of the aluminum alloy part. Secondly, when the flip fixture is used, by rotating the second screw rod, the second screw rod is a bidirectional screw rod, so that the two sets of sliding bases move toward each other, and the fixed clamp rod uses the rotating clamp block and the X-shaped groove to movably dock. When the sliding base moves, the rotating clamp block moves along the X-shaped groove, thereby adjusting the position between the four sets of fixed clamp rods, thereby completing the following steps: Fig. 9 The fixing operation of the plate-like member or column-like member is shown.

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0040] like Figure 1 As shown, a sandblasting treatment equipment for aluminum alloy parts comprises a fixed base 4 and a sealing cover 5, wherein the sealing cover 5 is fixedly mounted on the upper outer surface of the fixed base 4, a spray gun 12 is movably mounted inside the sealing cover 5, a flip fixture 10 for loading aluminum alloy parts is arranged on the upper end of the fixed base 4, the spray gun 12 and the sealing cover 5 are movably connected through a vertical slide rail 14 and a horizontal slide rail 15, the vertical slide rail 14 is movably mounted on both ends of the horizontal slide rail 15, a quadrangular cover 13 is fixedly sleeved on the output end of the spray gun 12, the flip fixture 10 comprises a first clamping plate 20, a second clamping plate 23 and a sliding base plate 24, the first clamping plate 20 and the second clamping plate 23 are both movably mounted on the upper outer surface of the sliding base plate 24, the first clamping plate 20 is movably mounted on one side of the second clamping plate 23, and a rotating chuck 21 is movably mounted on the middle position of the side edges of the first clamping plate 20 and the second clamping plate 23.

[0041] To solve the sandblasting control problems, such as Figure 2 and 3As shown, the spray gun 12 and the transverse slide 15 are slidably connected via a transverse slide 17, and the transverse slide 15 and the vertical slide 14 are connected via a vertical slide 18. Both the transverse slide 17 and the vertical slide 18 are driven by a linear motor. The transverse slide 17 cooperates with the transverse slide 15 to adjust the sandblasting position of the spray gun 12 laterally. Secondly, the vertical slide 18 cooperates with the vertical slide 14 to adjust the sandblasting height of the spray gun 12 up and down. The adjustment of the sandblasting height can control the spraying intensity and range. When the spray gun 12 is lower, the sand body sprayed by the spray gun 12 is more concentrated, the spraying distance is shorter, and the sandblasting intensity is greater. When the spray gun 12 is higher, the sand body sprayed by the spray gun 12 is more diffuse, the spraying distance is longer, and the sandblasting intensity is smaller. The user can adjust the use height of the spray gun 12 according to the type of aluminum alloy parts, thereby controlling the sandblasting intensity and range of the controller.

[0042] To improve the sandblasting effect, Figure 3 As shown, the spray gun 12 and the tetrahedral cover 13 are butt-jointed and fixed by a threaded sleeve 16. The outer surface of the tetrahedral cover 13 is a tetrahedral structure. A filter fan 7 is installed on the upper end of the sealing cover 5. The filter fan 7 can be used to filter and discharge the dust-containing gas. When the spray gun 12 performs close-range sandblasting on the surface of the aluminum alloy part, the tetrahedral cover 13 can effectively improve the sandblasting effect of the spray gun 12 on the aluminum alloy part, and reduce its dust phenomenon. When the sand body is sprayed out from the spray gun 12, the sand body hits the surface of the aluminum alloy part, and the sand body rebounds to the tetrahedral cover 13 after the impact. The tetrahedral cover 13 rebounds the sand body for the second time, so that the sand body repeatedly hits the surface of the aluminum alloy part, thereby realizing the rebound sandblasting treatment of the aluminum alloy part.

[0043] like Figure 2 As shown, a mesh plate 11 is provided at the bottom of the sealing cover 5, a sand collecting hopper 2 is provided at the bottom of the fixed base 4, and a discharge pipe 19 is fixedly installed at the lower end of the sand collecting hopper 2. The interior of the discharge pipe 19 is inclined. When the sand body is sprayed out from the spray gun 12, the sand body is discharged from the interior of the sealing cover 5 through the mesh plate 11, so that the sand body falls into the sand collecting hopper 2 and is discharged outward through the discharge pipe 19 of the sand collecting hopper 2.

[0044] like Figure 5 As shown, a discharge hopper 8 is fixedly installed at the middle position of the upper end of the sealing cover 5, and a return box 1 is installed at one end of the discharge pipe 19. One end of the discharge hopper 8 and the return box 1 are connected by a feeding auger 9. The feeding auger 9 can be used to transport the sand body discharged from the discharge pipe 19 into the return box 1 upward, and the used sand body is circulated and transported to the inside of the discharge hopper 8 through the feeding auger 9, and the discharge hopper 8 is used to transport the sand body to the inside of the spray gun 12 through the pipe body.

[0045] like Figure 1As shown, a boost pipe 6 is fixedly installed on the outer surface of one side of the sealing cover 5, and an air pump 3 is fixedly installed on the lower end of the boost pipe 6. The boost pipe 6 and the spray gun 12 are connected through a pipe body. The air pump 3 is used to generate high-pressure gas, and the gas is transported to the spray gun 12 through the boost pipe 6 and the pipe body. Two groups of joints are provided at one end of the spray gun 12, which can be connected to the two groups of pipe body structures respectively. The spray gun 12 is controlled by a solenoid valve. When the solenoid valve of the spray gun 12 is opened, the sand body in the spray gun 12 is sprayed out by high-pressure gas to achieve sandblasting of the aluminum alloy parts.

[0046] To solve the installation problem of materials of different specifications, such as Figure 5 As shown, the upper end of the sliding base 24 is provided with a sliding groove used in conjunction with the first clamping plate 20 and the second clamping plate 23, and the upper end of the sliding base 24 is a hollow structure. The sliding base 24 and the fixed base 4 are slidably connected by a sliding clamping strip 22. The user clamps the aluminum alloy part between the first clamping plate 20 and the second clamping plate 23, rotates the aluminum alloy part using the rotating chuck 21, pushes the flip clamp 10 into the interior of the sealing cover 5 using the sliding clamping strip 22, closes the sealing cover 5, and performs rotational sandblasting on the aluminum alloy part.

[0047] like Figure 6 As shown, the first clamping plate 20 and the second clamping plate 23 are driven by the first screw rod 25, and the rotating chuck 21 on one side of the first clamping plate 20 is driven by a motor. The first screw rod 25 is a bidirectional screw rod, so that when the first screw rod 25 rotates, the first clamping plate 20 and the second clamping plate 23 move toward each other, so that the rotating chuck 21 is clamped at both ends of the aluminum alloy part. The rotating chuck 21 is driven by the motor, so that the aluminum alloy part can rotate between the two sets of rotating chucks 21.

[0048] like Figure 7 As shown, four groups of fixed clamping rods 27 are movably installed on one side of the rotating chuck 21, and the fixed clamping rods 27 and the rotating chuck 21 are slidably connected through an X-shaped groove 26. A second screw rod 28 is movably installed on the inner side of the rotating chuck 21, and the interior of the rotating chuck 21 is a hollow structure. The four groups of fixed clamping rods 27 move synchronously along the X-shaped groove 26. The four groups of fixed clamping rods 27 can be used to fix the plate-like parts 32 or the columnar parts 33, thereby realizing the fixing operation of different types of aluminum alloy parts.

[0049] like Figure 8As shown, the lower ends of the four groups of fixed clamping rods 27 are all equipped with rotating clamping blocks 30, which are clamped on the inner side of the X-shaped groove 26, and the bottom of the rotating clamping block 30 is movably equipped with a docking slider 31, and the outer surface of the docking slider 31 is movably sleeved with a sliding base 29, and the two groups of sliding bases 29 are driven by the second screw rod 28. During operation, the second screw rod 28 is rotated, and the second screw rod 28 is a bidirectional screw rod, so that the two groups of sliding bases 29 move toward each other, and the fixed clamping rod 27 is movably docked between the rotating clamping block 30 and the X-shaped groove 26. When the sliding base 29 moves, the rotating clamping block 30 moves along the X-shaped groove 26, thereby adjusting the position between the four groups of fixed clamping rods 27.

[0050] When in use, the spray gun 12 structure of the conventional sandblasting equipment is installed in a fixed position. When performing the sandblasting operation, the aluminum alloy part is held by the operating port and the aluminum alloy part is manually sandblasted. The sandblasting force is affected by the sandblasting distance, and the sandblasting force cannot be accurately controlled during manual operation, making the surface of the aluminum alloy part rough and uneven, thereby reducing the treatment effect.

[0051] To this end, by setting a horizontal slide 17 and a vertical slide 18, when the aluminum alloy part sandblasting equipment is used, it has a movable spray gun 12 adjustment structure, which can flexibly control the sandblasting force and range of the spray gun 12, thereby improving the use effect of the sandblasting equipment;

[0052] During operation, the user installs the aluminum alloy parts to be processed on the inner side of the flip fixture 10, pushes the flip fixture 10 into the interior of the sealing cover 5, uses the air pump 3 to generate high-pressure gas, and transports the gas to the spray gun 12 through the booster pipe 6 in cooperation with the pipe body. One end of the spray gun 12 is provided with two sets of joints, which can be connected to the two sets of pipe body structures respectively. The sand body is transported to the spray gun 12 through the discharge hopper 8 in cooperation with the pipe body. The spray gun 12 is controlled by a solenoid valve. When the solenoid valve of the spray gun 12 is opened, the sand body in the spray gun 12 is sprayed out by high-pressure gas to achieve sandblasting of the aluminum alloy parts. The sandblasting position of the spray gun 12 can be adjusted horizontally by using the horizontal slide seat 17 in cooperation with the horizontal slide rail 15. Secondly, the sandblasting height of the spray gun 12 can be adjusted up and down by using the vertical slide seat 18 in cooperation with the vertical slide rail 14. , and the adjustment of the sandblasting height can control the spraying force and range. When the spray gun 12 is low, the sand body sprayed by the spray gun 12 is more concentrated, and the spraying distance is short, and the sandblasting force is large. When the spray gun 12 is high, the sand body sprayed by the spray gun 12 is more diffuse, and the spraying distance is long, and the sandblasting force is small. The user can adjust the use height of the spray gun 12 according to the type of aluminum alloy parts, thereby controlling the sandblasting force and range of the controller, and adjusting the sandblasting position with the horizontal slide 17. Secondly, the feeding auger 9 can be used to transport the sand body discharged from the discharge pipe 19 to the return box 1 upward, and the used sand body is circulated and transported to the inside of the discharge hopper 8 through the feeding auger 9, and the sand body is transported to the inside of the spray gun 12 through the pipe body by the discharge hopper 8, so as to complete the recycling of the sand body.

[0053] When sandblasting aluminum alloy parts, traditional equipment manually adjusts the position and angle of the aluminum alloy parts, so that the sand cannot be sprayed evenly on the surface of the aluminum alloy parts. At the same time, it cannot be flexibly applied to aluminum alloy parts of different widths, which reduces its use effect.

[0054] To this end, by setting the flip fixture 10, when the aluminum alloy part sandblasting treatment equipment is used, the use of the horizontal slide 17 and the vertical slide 18 is optimized, and the flipping and movement adjustment of the aluminum alloy part can be completed, thereby improving the sandblasting treatment effect;

[0055] When in use, the user clamps the aluminum alloy piece between the first clamping plate 20 and the second clamping plate 23. The first screw rod 25 is a bidirectional screw rod, so that when the first screw rod 25 rotates, the first clamping plate 20 and the second clamping plate 23 move toward each other, so that the rotating chuck 21 is clamped at the two ends of the aluminum alloy piece. The rotating chuck 21 is driven by the motor so that the aluminum alloy piece can rotate between the two sets of rotating chucks 21. The rotating chuck 21 is used to rotate the aluminum alloy piece. The bottom of the sliding clamping bar 22 is driven by an electric caster. The sliding clamping bar 22 is used to push the flip clamp 10 into the interior of the sealing cover 5, and the sealing cover 5 is closed to perform rotational sandblasting on the aluminum alloy piece. Secondly, the sliding clamping bar 22 can be used to adjust its position during the sandblasting of the aluminum alloy piece. The horizontal slide 17 cooperates with the position adjustment of the spray gun 12 to complete the overall sandblasting of the aluminum alloy piece, which is suitable for the sandblasting of the plate-like piece 32, and the rotation adjustment of the rotating chuck 21 on the aluminum alloy piece can be suitable for the sandblasting of the columnar piece 33.

[0056] When using traditional sandblasting equipment, the sand body rebounds and falls after being sprayed on the surface of the aluminum alloy part, so that the sand body can only complete the aluminum alloy part processing once, which reduces its sandblasting efficiency;

[0057] To this end, by providing the quadrangular cover 13 and the fixed clamping rod 27, when the aluminum alloy part sandblasting treatment equipment is used, the use of the vertical slide seat 18 can improve the sandblasting effect of the aluminum alloy part, and at the same time can be flexibly applied to different types of aluminum alloy parts;

[0058] During operation, the vertical slide 18 is used to adjust the position of the spray gun 12. When the spray gun 12 performs close-range sandblasting on the surface of the aluminum alloy part, the installation of the quadrangular cover 13 can effectively improve the sandblasting effect of the spray gun 12 on the aluminum alloy part, and reduce the dust phenomenon. When the sand body is ejected from the spray gun 12, the sand body hits the surface of the aluminum alloy part, and the sand body rebounds to the quadrangular cover 13 after the impact. The quadrangular cover 13 is used to rebound the sand body for the second time, so that the sand body repeatedly hits the surface of the aluminum alloy part, and the rebound sandblasting treatment of the aluminum alloy part is achieved. Secondly, when the flip fixture 10 is used, by rotating the second screw rod 28, the second screw rod 28 is a bidirectional screw rod, so that the two groups of sliding bases 29 move toward each other, and the fixed clamp rod 27 is movably connected between the rotating clamp block 30 and the X-shaped groove 26. When the sliding base 29 moves, the rotating clamp block 30 moves along the X-shaped groove 26, thereby adjusting the position between the four groups of fixed clamp rods 27, thereby completing the following operation: Fig. 9 The fixing operation of the plate-shaped member 32 or the column-shaped member 33 is shown.
