Description
Technical Field
[0001] The utility model relates to the technical field of shot blasting machines, and particularly relates to a shot blasting machine for cleaning the surface of waste engine parts. Background Technique
[0002] The main reason for shot blasting the engine is to improve its fatigue life and corrosion resistance. Shot blasting treatment impacts the surface of the workpiece by high-speed moving shot, forcing the surface layer structure to be modified and introducing residual compressive stress, thereby improving the fatigue strength and corrosion resistance of the part. Moreover, it can also remove the dirt on the engine surface and make the engine surface look brand new.
[0003] When the existing shot blasting machine is in use, ropes need to be installed at the connection points of the engine, and then the engine is hung on the hook inside the shot blasting machine body. However, the engine is heavy and extremely inconvenient to lift. For this reason, we propose a shot blasting machine for cleaning the surface of waste engine parts. Content of the Utility Model

A support shaft is movably provided in the support cylinder. The bottom of the support shaft extends from the strip-shaped opening into the box body, and a hanging rack is provided at the bottom of the support shaft. The top of the support shaft is rotatably provided in a support seat, and the support seat is connected to a second linear driving device vertically arranged on the vertical frame body. At least one keyway parallel to its axis is provided on the inner wall of the support cylinder, and at least one limiting strip parallel to its axis is provided on the surface of the support shaft. The limiting strip is matched with the keyway and is movably placed in the keyway. It also includes a support frame body located on the side of the bottom of the vertical frame body away from the support sleeve and parallel to the strip-shaped opening. A first linear driving device is provided at the top of the support frame body, and the bottom of the vertical frame body is connected to the first linear driving device through a fixed bracket.
[0006] Preferably, the driving device includes a driving motor installed on the vertical frame body.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1 to 4 This utility model provides a technical solution: a shot blasting machine for cleaning the surface of waste engine parts, including a housing 19, with sealing doors 22 rotatably installed on both sides of the housing 19, the sealing doors 22 being connected by a lock, and a shot blaster 18 provided on the side of the housing 19, such as... Figure 1 As shown, the bottom of the box 19 is provided with a conical bottom 20, and the bottom of the box 19 is provided with multiple support legs 23, which are set on the ground;
[0024] The bottom of the conical bottom 20 is connected to the inlet at the bottom of the spiral conveyor cylinder 13 via a downwardly sloping pipe 31. The spiral conveyor cylinder 13 is located on one side of the housing 19, and its top extends above the top of the housing 19. Figure 2 As shown, the screw conveyor 13 is fixed to the side of the box 19 by the connecting seat 28 to keep the screw conveyor 13 stable. The top outlet of the screw conveyor 13 is connected to an inclined downward dropping pipe 14.
[0025] A hopper 17 is connected to the inlet of the shot blaster 18, and the top of the hopper 17 is connected to the lower end of the discharge pipe 14. In actual use, the shot is poured into the conical bottom 20 for storage. The volume of the shot poured into the conical bottom 20 should not exceed two-thirds of the volume of the conical bottom 20. In this way, the shot can flow into the spiral conveyor 13 along the pipe 31, and then be lifted upward by the spiral conveyor 13 and flow out from the discharge pipe 14, and finally fall into the hopper 17, so that the shot continuously flows into the shot blaster 18. The shot blaster 18 is connected to the inside of the box 19. The shot is thrown out by the shot blaster 18, so that the shot is scattered in a fan shape inside the box 19.
[0026] After prolonged use, the feed needs to be replaced, such as... Figure 2 As shown, a discharge valve 29 is installed on the side of the spiral conveyor 13 near the pipe 31. When the discharge valve 29 is opened, the upward conveying path of the shot along the spiral conveyor 13 is cut off, so that the shot is continuously discharged from the discharge valve 29, thereby discharging all the shot in the conical bottom 20. Then, new shot can be poured into the conical bottom 20.
[0027] Furthermore, such as Figure 1 As shown, a strip-shaped opening 16 is provided in the center of the top surface of the box 19, penetrating one side of the box 19, i.e., the strip-shaped opening 16 is located at the sealing door 22. A support sleeve 25 is provided directly above the strip-shaped opening 16, and the support sleeve 25 is mounted on a fixed base 24. The fixed base 24 is mounted on the bottom side of the vertical frame 27. A support cylinder 6 is coaxially rotatable inside the support sleeve 25, and one end of the support cylinder 6 is driven to rotate by a driving device. Figure 1 and Figure 4 As shown, the driving device includes a drive motor 7 mounted on a vertical frame 27. The shaft of the drive motor 7 is located at the support cylinder 6 and the two are perpendicular. Meshing bevel gears 26 are mounted on the support cylinder 6 and the shaft. When the drive motor 7 rotates, the bevel gears 26 drive the support cylinder 6 to rotate within the support sleeve 25. The support sleeve 25 has a cylindrical structure, which increases its contact area with the support cylinder 6, providing better support. Furthermore, the diameter of the bevel gear on the drive motor 7 is the same as the diameter of the bevel gear on the support cylinder 6, so that a smaller gear drives a larger gear, making the drive motor 7 work more efficiently.
[0028] like Figure 1 As shown, a support shaft 12 is movably installed inside the support cylinder 6, that is, the support shaft 12 is movably placed inside the support cylinder 6, so that the support shaft 12 can extend and retract along the support cylinder 6. The bottom of the support shaft 12 extends from the strip opening 16 into the housing 19, and a bracket 21 is provided at the bottom of the support shaft 12. The bracket 21 is in the shape of "I", "+" or "M". Multiple hooks are provided at the bottom of the bracket 21. The bracket 21 is used to connect with the rope connecting the engine, so that the engine is hung below the bracket 21.
[0029] Next, at least one keyway (unnumbered) parallel to its axis is provided on the inner wall of the support cylinder 6, and at least one limiting strip 11 parallel to its axis is provided on the surface of the support shaft 12. The limiting strip 11 matches the keyway and is movably placed in the keyway. Due to the cooperation between the limiting strip 11 and the keyway, the support shaft 12 can only move along the axis of the support cylinder 6.
[0030] The top of the support shaft 12 is supported by the support 10, and the top of the support shaft 12 is rotatably mounted inside the support 10. The support 10 is connected to a second linear drive device vertically mounted on the vertical frame 27. The second linear drive device includes a second linear drive module 8 and a second support rail 9 vertically mounted on the side of the vertical frame 27. There is at least one second support rail 9. The support 10 is slidably connected to the second support rail 9 via a slider, and is also slidably connected to the second linear drive module 8. The second linear drive module 8 can drive the support 10 to move up and down along the second support rail 9. Therefore, the support 10 can extend and retract up and down in the support cylinder 6 when the support shaft 12 rotates, thereby allowing the hanger 21 to rise and fall.
[0031] Furthermore, it also includes a support frame located at the bottom of the vertical frame 27 away from the support sleeve 25 and parallel to the strip opening 16. The support frame is used to support the vertical frame 27. The support frame includes a support beam 5 located above the top of the box 19. One end of the support beam 5 extends to the outside of the box 19, and the end of the support beam 5 is provided with a support column 1. The support column 1 is set on the ground, and the end of the support beam 5 away from the support column 1 is connected to the top of the box 19 through the mounting seat 15.
[0032] A reinforcing frame 2 is provided parallel below the support beam 5. The reinforcing frame 2 is located on one side of the bottom of the vertical frame 27. The two ends of the reinforcing frame 2 are connected to the mounting base 15 and the support column 1, respectively. The reinforcing frame 2 can enhance the stability between the support column 1 and the mounting base 15.
[0033] The top of the support frame is equipped with a first linear drive device, and the bottom of the vertical frame 27 is connected to the first linear drive device via a fixed bracket 30, such as... Figure 1As shown, the first linear drive device includes a first support guide rail 3 installed on the side of the reinforcing frame 2 and the top of the support beam 5. There are at least two first support guide rails 3, and the bottom of the vertical frame 27 and the bottom of the fixed bracket 30 are respectively connected to the first support guide rail 3 via sliders. A first linear drive module 4 connected to the fixed bracket 30 is also provided on the top of the support beam 5. The first linear drive module 4 can drive the vertical frame 27 to reciprocate along the first support guide rail 3.
[0034] In summary, the first linear drive module 4 can drive the vertical frame 27 to move outwards from the housing 19, and then stop the vertical frame 27 outside the housing 19. Then, control the second linear drive module 8 to drive the support shaft 12 downwards, so that the bracket 21 located at the bottom of the support shaft 12 is placed above the ground. Then, the engine is hung at the bottom of the bracket 21 by a rope. Then, control the second linear drive module 8 to drive the support shaft 12 upwards, so that the engine is raised to a preset height. Then, control the first linear drive module 4 to drive the vertical frame 27 to move inwards from the housing 19, so that the support shaft 12 enters the slot 16. At this time, close the sealing door 22, turn on the spiral conveyor 13 and the shot blaster 18, so that the shot blaster 18 can throw the shot towards the engine. The drive motor 7 continuously drives the support shaft 12 to rotate, so that the engine rotates around the shot blaster 18, so that all parts of the engine surface are in contact with the shot.
[0035] Conversely, once the shot blasting time is reached, the sealing door 22 can be opened, and then the first linear drive module 4 can be controlled to move to the outside of the housing 19 again, and the support shaft 12 can be lowered, after which the engine can be removed.
[0036] Based on the above embodiments, further optimization is possible. During the shot blasting process, a large amount of dust is generated. The top of the chamber 19 is connected to a pipe vacuum cleaner to reduce the dust inside the chamber 19. In addition, at least one air inlet is provided on the top of the chamber 19, and a filter screen is provided inside the air inlet to ensure the air pressure balance inside the chamber 19.
[0037] Based on the above embodiments, it should be further noted that the first linear drive module 4 and the second linear drive module 8 are belt linear modules, lead screw linear modules, or linear drive motors.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
