Description

Technical Field

[0001] This utility model belongs to the field of engine sandblasting technology, specifically a multi-angle sandblasting device for engine remanufacturing. Background Technology

[0002] Engine remanufacturing refers to the professional repair and upgrading of used engines to restore them to their original factory specifications, or even perform engineering upgrades to achieve the performance of new parts and provide the same warranty. This process includes multiple stages such as disassembly, cleaning, surface treatment, machining, secondary surface treatment, assembly, and testing. Engine remanufacturing sandblasting equipment is a type of equipment used for the remanufacturing of engine parts. It is mainly used for surface treatment of engine parts, including removing old coatings, rust, burrs, and attached inorganic dirt, as well as enhancing the adhesion between the dimensional restoration layer and the base material. When using existing sandblasting equipment, most of them are operated by workers holding the spray gun to spray the engine from multiple angles, which is inefficient. Long-term operation will cause worker fatigue and affect the efficiency of sandblasting operations. Sand will splash onto workers, which not only wastes sand resources, but also easily splashes into their eyes, posing a threat to the health of workers. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a multi-angle sandblasting device for engine remanufacturing. It solves the problems that most sandblasting devices rely on workers holding spray guns to spray the engine from multiple angles, which is inefficient. Prolonged operation can cause worker fatigue, affecting the efficiency of sandblasting operations. Sand can also splash onto workers, wasting sand resources and easily getting into their eyes, posing a threat to their health.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle sandblasting device for engine remanufacturing, comprising a base, a bracket fixedly connected to the base, an annular groove formed on the bracket, an electric telescopic rod slidably connected to the inner wall of the annular groove, a gear rail fixedly connected to one side of the inner wall of the annular groove, a slide rail formed on the side of the inner wall of the annular groove away from the gear rail, a mounting block provided on one side of the electric telescopic rod, a sliding wheel fixedly connected to one side of the mounting block, the sliding wheel slidably connected to the slide rail, a sandblasting gun fixedly connected to one end of the electric telescopic rod, a first motor fixedly connected to one side of the electric telescopic rod, the first motor having a first gear provided through its output shaft, the first gear meshing with the gear rail.

[0005] As a further embodiment of this utility model: a second motor is fixedly connected to one side of the base, and the second motor is provided with a transmission belt structure through its output shaft, and two lead screws are provided on one side of the transmission belt structure.

[0006] As a further embodiment of this utility model: the lead screw is externally threaded to a movable seat, the movable seat is slidably connected to the base, an electric lifting rod is fixedly connected to the center of the top of the movable seat, and a limit sliding rod is movably connected around the top of the movable seat.

[0007] As a further embodiment of this utility model: the electric lifting rod is provided with a lifting platform, a placement platform is rotatably connected to the lifting platform, a limit groove is provided under the placement platform, and the limit groove is slidably connected to the limit slide rod.

[0009] As a further embodiment of this utility model: a bidirectional threaded rod is rotatably connected to the top of the placement platform, a turntable is installed through the placement platform via the bidirectional threaded rod, and a clamping seat is symmetrically connected to the external threads of the bidirectional threaded rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The engine remanufacturing multi-angle sandblasting device is equipped with a first motor, a first gear, a gear rail, and an electric telescopic rod. The first motor drives the first gear to rotate through the output shaft. The first gear drives the electric telescopic rod to slide inside the annular groove through gear meshing with the gear rail.

This facilitates the movable seat to move the engine between the brackets for sandblasting. The third motor drives the second gear to rotate via its output shaft, which in turn drives the placement platform to rotate through its meshing with the gear ring. This allows for more comprehensive sandblasting of the engine and improves the practicality of the device. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a multi-angle sandblasting device for engine remanufacturing, including a base 1, a second motor 12 fixedly connected to one side of the base 1, a transmission belt structure 13 provided on the output shaft of the second motor 12, and two lead screws 14 provided on one side of the transmission belt structure 13. By providing the transmission belt structure 13, when the second motor 12 is running, it can drive the two lead screws 14 to rotate together through the transmission belt structure 13, so that the lead screws 14 can drive the movable seat 15 to move more stably.

[0019] The lead screw 14 is externally threaded to a movable seat 15, which is slidably connected to the base 1. An electric lifting rod 16 is fixedly connected to the center of the top of the movable seat 15. Limiting slide rods 25 are movably connected around the top of the movable seat 15. A lifting platform 17 is provided on the electric lifting rod 16. By providing the electric lifting rod 16, the electric lifting rod 16 can drive the lifting platform 17 to move upward, so that the engine on the placement platform 21 can get closer to the sandblasting gun 9, thereby improving the spraying effect of the sandblasting gun 9.

[0020] A placement platform 21 is rotatably connected to the lifting platform 17. A limit groove 26 is provided under the placement platform 21. The limit groove 26 is slidably connected to the limit slide rod 25. A third motor 18 is fixedly connected to the lower part of the lifting platform 17. The third motor 18 is equipped with a second gear 19 through its output shaft. A gear ring 20 is fixedly connected to the lower part of the placement platform 21. The gear ring 20 is meshed with the second gear 19. By setting the limit slide rod 25, when the third motor 18 drives the placement platform 21 to rotate through the second gear 19, the limit groove 26 under the placement platform 21 will slide outside the limit slide rod 25, so that the limit slide rod 25 can limit the limit groove 26, thereby improving the stability of the placement platform 21 when rotating.

[0021] A bidirectional threaded rod 23 is rotatably connected to the top of the placement platform 21. A turntable 22 is installed through the bidirectional threaded rod 23. A clamping seat 24 is symmetrically connected to the external threads of the bidirectional threaded rod 23. By setting the turntable 22, rotating the turntable 22 causes the bidirectional threaded rod 23 to rotate, which in turn causes the clamping seat 24 to move relative to each other, thereby clamping and fixing the engine located between the clamping seats 24. When the bidirectional threaded rod 23 drives the clamping seat 24 to move relative to each other, the clamping seat 24 slides inside the placement platform 21, thereby allowing the placement platform 21 to limit the clamping seat 24.

[0022] A bracket 2 is fixedly connected to the base 1. An annular groove 3 is provided on the bracket 2. An electric telescopic rod 8 is slidably connected to the inner wall of the annular groove 3. A toothed rail 4 is fixedly connected to one side of the annular groove 3. A slide rail 5 is provided on the side of the inner wall of the annular groove 3 away from the toothed rail 4. An installation block 7 is provided on one side of the electric telescopic rod 8. A sliding wheel 6 is fixedly connected to one side of the installation block 7. The sliding wheel 6 is slidably connected to the slide rail 5. By setting the annular groove 3, when the first motor 10 drives the electric telescopic rod 8 to slide in the annular groove 3, the sliding wheel 6 on one side of the electric telescopic rod 8 will slide inside the slide rail 5 at the same time. This allows the slide rail 5 to limit the sliding wheel 6, thereby improving the stability of the electric telescopic rod 8 when it moves.

[0023] One end of the electric telescopic rod 8 is fixedly connected to a sandblasting gun 9, and a first motor 10 is fixedly connected to one side of the electric telescopic rod 8. The first motor 10 is equipped with a first gear 11 through its output shaft. The first gear 11 meshes with the gear rail 4. By setting the electric telescopic rod 8, the electric telescopic rod 8 can drive the sandblasting gun 9 to extend and retract, so that the sandblasting gun 9 can adjust the sandblasting distance according to different specifications of engines, thereby realizing sandblasting treatment of engines of different specifications.

[0024] The working principle of this utility model is as follows:

[0025] In use, the engine to be processed is placed between the clamping seats 24 on the placement table 21. Then, the turntable 22 is rotated, causing the double-threaded rod 23 to rotate. The rotation of the double-threaded rod 23 causes the clamping seats 24 to move relative to each other, securing the engine tightly against both sides. The second motor 12 is then started, causing the lead screw 14 to rotate via the transmission belt structure 13. This allows the movable seat 15 outside the lead screw 14 to move inwards towards the bracket 2 as the lead screw 14 rotates. Finally, the electric lifting rod 16 and the electric telescopic rod 8 are activated. When the engine is brought close to the sandblasting gun 9, the sandblasting gun 9 and the first motor 10 are started. While the sandblasting gun 9 is sandblasting the engine, the first motor 10 drives the first gear 11 to rotate on the gear rail 4, which in turn drives the electric telescopic rod 8 to move in an arc, allowing the sandblasting gun 9 to sandblast the engine from multiple angles. Then, the third motor 18 is started. The third motor 18 drives the second gear 19 to rotate, which in turn drives the placement platform 21 on the gear ring 20 to rotate through the meshing of the second gear 19 and the gear ring 20, thereby rotating the engine and facilitating a more comprehensive sandblasting process for the engine.
