[0002] Aluminum shot blasting machines mainly remove impurities, oxide layers, oil stains, and processing marks from the surface of aluminum parts by blasting shot, so that the surface of aluminum parts can achieve the predetermined cleanliness and roughness, and can strengthen the surface properties of aluminum parts to a certain extent, improve their fatigue strength and corrosion resistance, thereby meeting the requirements of subsequent processing, assembly or use of aluminum parts.

[0003] Traditional shot blasting machines have end covers that are inconvenient to open and close stably, which can easily lead to shot being thrown out and causing safety accidents. In addition, existing shot blasting machines are not convenient for separating materials and impurities, making them inconvenient to use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an aluminum shot blasting cleaning machine.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an aluminum shot blasting machine, comprising a housing, a shot blasting machine, support legs, a protective assembly, and a load-bearing assembly. The housing has an open load-bearing cavity on its front side. The support legs are located at the four corners of the lower part of the housing. The shot blasting machine is also located on top of the housing, with its output end penetrating the top wall of the load-bearing cavity. The protective assembly includes a motor, a worm gear, a worm wheel, a frame, a connecting shaft, a gear, a rack, a housing cover, and a support frame. Support frames are symmetrically arranged on the left and right sides of the housing. A lifting groove is also provided on the side of the support frame near the center of the housing. The housing cover is adapted to the opening. Racks that are slidably connected to the lifting groove are symmetrically arranged on the left and right sides of the housing cover. Frames are symmetrically arranged on the left and right sides of the upper part of the housing. A worm wheel is located at the center of the connecting shaft. The connecting shaft passes through the corresponding frames on the left and right sides and is connected to the center of the gear. The gear meshes with the rack. The output end of the motor is connected to the worm gear, which meshes with the worm wheel. The load-bearing assembly is also provided inside the load-bearing cavity.

[0008] To facilitate the filtration of materials and impurities, this utility model is improved by including a material-carrying box with an opening at the top and a filter assembly, wherein the filter assembly is disposed inside the material-carrying box.

[0009] Preferably, the filter assembly includes an elastic element, a top frame, and a filter frame.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an aluminum shot blasting cleaning machine, which has the following beneficial effects:

[0015] This aluminum shot blasting machine starts its motor when the cover needs to be opened. The motor drives the worm gear to rotate precisely. Based on the worm gear transmission principle, the worm gear drives the worm wheel to rotate, which in turn drives the connecting shaft and the gears at both ends of the connecting shaft to rotate synchronously. Based on the gear and rack transmission principle, the rotation of the gear drives the meshing rack to move upward in a straight line along the lifting groove of the support frame, thereby causing the cover to rise and open smoothly, providing convenient operating space for placing or removing aluminum parts. Because a servo motor is used, the rotation angle, rotation speed and other parameters of the motor can be precisely controlled, thereby accurately adjusting the lifting height of the cover so that it can be stably stopped in the appropriate position. This avoids the situation of accidental closure or excessive opening due to instability during the opening and closing of the end cover of traditional shot blasting machines.

[0016] The load-bearing components facilitate the separation of materials and impurities, and make it easy to centrally transfer impurities and materials, making operation convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A shot blasting machine for aluminum parts includes a housing 1, a shot blasting machine 2, support legs 3, a protective assembly, and a load-bearing assembly. The housing 1 has an open load-bearing cavity on its front. The support legs 3 are located at the four lower corners of the housing 1. The shot blasting machine 2 is also located on top of the housing 1, with its output end penetrating the top wall of the load-bearing cavity. The protective assembly includes a motor 4, a worm gear 5, a worm wheel 6, a frame 7, a connecting shaft 8, a gear 9, a rack 10, a housing cover 11, and a support frame 12. The support frames 12 are symmetrically arranged on the left and right sides of the housing 1. A lifting groove is provided on one side near the center of the box body 1. The box cover 11 is adapted to the opening. The box cover 11 is symmetrically provided with racks 10 that are slidably connected to the lifting groove on both the left and right sides. The box body 1 is symmetrically provided with frames 7 on the left and right sides above. The connecting shaft 8 is provided with a worm gear 6 at its center. The connecting shaft 8 passes through the corresponding frames 7 on the left and right sides and is connected to the center of the gear 9. The gear 9 meshes with the racks 10. The output end of the motor 4 is connected to the worm 5. The worm 5 meshes with the worm gear 6. The bearing cavity is also provided with a bearing component.

[0024] The housing 1 serves as the foundation of the entire equipment, with its open-faced bearing chamber forming the core space for the shot blasting operation. Aluminum parts are placed within this chamber, its dimensions designed to ensure sufficient space and full exposure to the shot blasting range for impact cleaning by the shot propelled by the shot blasting machine 2. Four support legs 3 at the bottom corners of the housing 1 provide stable support, allowing it to rest stably on the ground or other operating surfaces. This ensures that shaking during operation does not affect the shot blasting effect or the normal coordinated operation of other components. The shot blasting machine 2 is mounted above the housing 1, its output end penetrating the top wall of the bearing chamber. During operation, the shot blasting device inside the shot blasting machine 2 (typically including key components such as impellers and shot distributors; the shot first enters the distributor for acceleration, then is propelled out at high speed by the impeller) accelerates the shot to a certain high speed and propels it towards the surface of the aluminum parts within the bearing chamber in a predetermined direction. Upon impact, the shot's kinetic energy removes impurities (such as oxide layers, oil stains, and machining marks) from the aluminum surface.

[0025] The supporting component includes a material box 13 with an opening at the top and a filter component, wherein the filter component is disposed inside the material box 13;

[0026] After motor 4 (a servo motor 4, capable of precise rotation control) starts, the output of motor 4 drives worm 5 to rotate. Worm 5 meshes with worm wheel 6. According to the transmission principle of worm wheel 6 and worm 5, the rotation of worm 5 drives worm wheel 6 to rotate. Connecting shaft 8 passes through the center of worm wheel 6, and the left and right sides of connecting shaft 8 pass through the corresponding frame 7 and are connected to the center of gear 9. Therefore, the rotation of worm wheel 6 will drive connecting shaft 8 and gear 9 at both ends of connecting shaft 8 to rotate synchronously.

[0027] The racks 10 symmetrically arranged on the left and right sides of the cover 11 mesh with the gears 9, and the racks 10 are slidably connected to the lifting grooves on the support frame 12. When the gear 9 rotates, based on the transmission principle of the gear 9 and rack 10, the rack 10 will move linearly along the lifting grooves of the support frame 12. If the motor 4 rotates in the forward direction, it drives the gear 9 to rotate and move the rack 10 upward, thereby causing the cover 11 to rise and open smoothly along the lifting groove, providing convenient operating space for operators to place or remove aluminum parts. Because a servo motor 4 is used, the rotation angle, rotation speed and other parameters of the motor 4 can be precisely controlled, so that the lifting height of the cover 11 can be accurately adjusted and it can be stably stopped in a suitable position, without accidental closing or excessive opening. This is in stark contrast to the unstable opening and closing of the end cover of the traditional shot blasting machine.

[0028] During shot blasting, the cover 11 is closed, and the self-locking characteristic of the worm gear 6 and worm 5 transmission takes effect, ensuring that the cover 11 is firmly kept in the closed state. This effectively prevents the shot blasting machine 2 from being thrown out of the opening, avoids the shot spillage and safety accidents, and ensures the safety of the operators and the surrounding working environment.

[0029] In addition, the cover 17 set on the top wall of the housing 1 covers the worm gear 6 and worm 5. First, it can prevent external dust and debris from entering the transmission component area, ensuring that the transmission system can operate stably and reliably. Second, it can enhance the overall stability of the assembly of the worm gear 6 and worm 5, ensure the smoothness and continuity of the opening and closing action of the cover 11, and further improve the reliability of the protective components.

[0030] The load-bearing components can hold materials and separate impurities;

[0031] The filter assembly includes elastic elements 14, a top frame 15, and a filter frame 16. The elastic elements 14 are located at the four corners of the material box 13. The top frame 15 is also located on the outside of the filter frame 16. The elastic elements 14 are connected to the top frame 15. The filter frame 16 is also provided with several sets of filter holes. The material box 13 in the bearing assembly has an upper opening to facilitate the placement of aluminum parts into it. When placed in the bearing cavity, the aluminum parts are placed within the action area of ​​the shot blasting machine 2. The elastic elements 14 in the filter assembly are installed at the four corners of the material box 13. The top of the elastic elements 14 is connected to the top frame 15 on the outside of the filter frame 16. Under normal conditions, the elastic elements 14 support the filter frame 16 in a suitable position through the top frame 15. The filter frame 16 is provided with several sets of filter holes. During the shot blasting process, after the shot impacts the aluminum part, the impurities removed (such as aluminum shavings, dust, and smaller particles such as potentially broken shot) will fall through the filter holes of the filter frame 16 under the action of gravity, while the aluminum part, due to its relatively large size, remains above the filter frame 16, thus achieving initial separation of materials and impurities. The material container 13 has a through hole at the bottom, and a sliding plate 18 slidably connected to the through hole is provided on the front of the material container 13. The through hole at the bottom of the material container 13 and the sliding plate 18 slidably connected to the through hole on the front facilitate further separation and centralized transfer of impurities. After the shot blasting operation has been running for a period of time, impurities accumulate at the bottom of the material container 13. At this time, simply pull out the sliding plate 18, and the impurities accumulated at the bottom of the material container 13 can be smoothly discharged through the through hole into an external collection device (such as a collection bucket), achieving centralized collection and treatment of impurities.
