Specifically, the engine block, as one of the core parts of the engine, undertakes important functions such as supporting the cylinders, gas exchange, and cooling.

[0003] Magnesium alloy engine blocks are a key automotive component requiring lightweight and high strength, and their surface treatment processes are crucial to product performance. Sandblasting technology is a core step in the manufacturing process of magnesium alloy engine blocks, effectively removing burrs, optimizing surface roughness, enhancing coating adhesion, and improving corrosion resistance.

[0004] In existing technologies, sandblasting devices for magnesium alloy engine cylinder blocks continuously spray out sand that mixes with the dust that falls off the outside of the magnesium alloy engine cylinder block during use. This requires manual separation by the staff, which is time-consuming. Furthermore, the sandblasting process requires the staff to precisely swing the entire gun to remove dust or rust from the outside of the cylinder block, making it difficult to flexibly adjust the nozzle angle in the sandblasting gun.

[0005] Therefore, a sandblasting device for the preparation of magnesium alloy engine cylinder blocks is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] 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.

[0025] Example:

[0026] Please see Figure 1 - Figure 4 The sandblasting device for preparing a magnesium alloy engine cylinder block in this embodiment includes a sandblasting device body 1, a support plate 2 fixedly connected to the outer surface of the sandblasting device body 1, a motor 3 fixedly connected to the upper surface of the support plate 2, a first pulley 4 fixedly connected to the output end of the motor 3, at least two connecting shafts 5 rotatably connected to the bottom of the sandblasting device body 1, a second pulley 6 fixedly connected to the other end of one connecting shaft 5, a belt body 7 provided between the second pulley 6 and the first pulley 4, and the other end of the other connecting shaft 5 fixedly connected to the output end of the motor 3.

[0027] At least two connecting shafts 5 are symmetrically fixedly connected to cams 8 on their outer surfaces. The bottom of the sandblasting device body 1 is provided with several limiting grooves 9. Each limiting groove 9 is fixedly connected to a first spring 10. The top of the first spring 10 is fixedly connected to a connecting plate 11. A filter plate 12 is fixedly connected between the connecting plates 11. A spherical block 13 is fixedly connected to the lower surface of the filter plate 12. The spherical block 13 abuts against the cam 8.

[0028] During the removal process, dust and sprayed sand fall from the perforated plate 24 into the interior of the filter plate 12. At this time, the motor 3 on the upper surface of the support plate 2 is started, and the output end of the motor 3 drives the first pulley 4 to rotate. The belt body 7 outside the first pulley 4 causes the connecting shaft 5 and the second pulley 6 to rotate together. The rotation of the connecting shaft 5 drives the cam 8 to rotate. When the protruding part of the cam 8 abuts against the spherical block 13, the spherical block 13 will drive the filter plate 12 to move upward. When the cam 8 separates from the spherical block 13, the filter plate 12 will descend. This process is repeated continuously, so that the dust and sand inside the filter plate 12 are filtered and separated.

[0029] At this time, the first spring 10 is fixed inside by the limiting groove 9, and the connecting plate 11 is fixed by the first spring 10. With the cooperation of the connecting plate 11 and the first spring 10, the filter plate 12 is fixed and plays a buffering role.

[0030] A sand box 14 is fixedly connected to the outer surface of the sand blasting device body 1. A sand outlet pipe 15 is fixedly connected inside the sand box 14. A sand blasting gun body 16 is fixedly connected to the other end of the sand outlet pipe 15. A connector 17 is fixedly connected to the other end of the sand blasting gun body 16. Several second springs 18 are fixedly connected inside the connector 17. A running block 19 is fixedly connected to the other end of the second springs 18. A sand outlet 20 is opened inside the running block 19.

[0031] The connector 17 is rotatably connected to a longitudinal rotating shaft 21, the other end of which is movably connected to the running block 19. The connector 17 is also rotatably connected to a transverse rotating shaft 22, the other end of which is movably connected to the running block 19. A sandblasting head 23 is fixedly connected to the outer surface of the running block 19.

[0032] A blasting plate 24 is fixedly connected inside the sandblasting device body 1. The upper surface of the blasting plate 24 abuts against the sandblasting gun body 16. A transparent plate 25 is fixedly connected to the outer surface of the sandblasting device body 1. A switch door 26 is provided on the front side of the outer surface of the sandblasting device body 1. A tension-relaxation hand inlet 27 is symmetrically arranged inside the switch door 26. At least two tension-relaxation hand inlets 27 are provided with openings 28 inside.

[0033] In use, the operator opens the switch door 26 on the front side of the YY-10A sandblasting device body 1, places the magnesium alloy engine block above the blasting plate 24 inside the sandblasting device body 1, and then closes the switch door 26. The operator's two hands are inserted through the elastic hand inlet 27 and opening 28. The internal structure of the elastic hand inlet 27 and opening 28 can be made of elastic cloth and elastic rope to reduce dust entering the sandblasting device body 1. The inside of the sandblasting device body 1 can be viewed through the transparent plate 25. The sand in the sand box 14 is brought into the sand outlet pipe 15, which drives the sandblasting gun body 16. Then, the sandblasting gun body 16 is used to remove dust and other impurities from the surface of the magnesium alloy engine block.

[0034] Meanwhile, during the sandblasting process, the operator can open the switch door 26 and rotate the longitudinal shaft 21 according to the needs of the work. The longitudinal shaft 21 drives the running block 19 to rotate longitudinally. Since the running block 19 rotates inside the connector 17, it drives the sandblasting head 23 to swing together, hence the name running block 19. If the transverse shaft 22 is rotated, the running block 19 and the sandblasting head 23 will swing laterally. The angle of the sandblasting head 23 can be adjusted as needed. The sandblasting head 23 is an integral structure of the sandblasting gun body 16 of model H-100. It is driven by compressed air to bring the sand in the sand box 14 into the sandblasting gun body 16. By setting multiple second springs 18 inside the connector 17, the running block 19 has a limit during rotation. At the same time, the sand can be brought into the sandblasting head 23 and sprayed out through the sand outlet 20.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
