Description

Technical Field

[0001] This utility model belongs to the field of automatic cleaning equipment, specifically relating to an automatic cleaning device for the crystallization plate of an aero-engine blade casting furnace. Background Technology

[0002] The precision casting furnace for aero-engine blades is designed with a brass crystallizing plate. After melting alloy steel bars, the furnace pours the melted steel into the mold. Because the mold rests on the crystallizing plate, molten metal splashes onto the plate during casting, contaminating its surface. After each casting, the plate must be manually wiped clean with a scouring pad, which is inefficient and increases the workload for workers. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automatic cleaning device for the crystallization plate of the aero-engine blade casting furnace.

[0004] To achieve the above and other related objectives, this utility model provides an automatic cleaning device for the crystallization plate of an aero-engine blade casting furnace. The automatic cleaning device includes a robotic arm, a clamping member installed at the end of the robotic arm, and a cleaning mechanism that can be clamped on the clamping member. The cleaning mechanism includes a chassis, a scouring pad placed on the bottom surface of the chassis, a cover plate placed on the top surface of the chassis and used to clamp the periphery of the scouring pad, at least one guide rod that is vertically fixedly connected to the top surface of the chassis, and a top plate that is movably disposed at the top of the guide rod and can be clamped by the clamping member. The top plate has a vertical hole through which the guide rod can pass. The middle part of the guide rod has a boss protruding from the outer wall surface of the guide rod. A spring is provided between the boss and the top plate. The spring is sleeved on the guide rod. The top of the guide rod has a locking nut that locks the guide rod and prevents the guide rod from passing through the vertical hole.

[0005] Optionally, the top of the guide rod is provided with an external thread that can be screwed into the locking nut.

[0006] Optionally, a flange is fixedly fitted inside the vertical hole, and the flange has a through hole in the middle through which the guide rod can pass.

[0007] Optionally, the periphery of the flange is fixedly connected to the top plate by a first bolt, the top end of the spring elastically abuts against the flange, and the bottom end of the spring elastically abuts against the boss.

[0008] Optionally, the chassis and the cover plate are fixedly connected by a second bolt, and the periphery of the scouring pad is folded upward along the periphery of the chassis plate and then clamped between the top surface of the chassis and the bottom surface of the cover plate.

[0009] Optionally, the outer side wall of the top plate is provided with an arc-shaped flange, which surrounds the outer side wall of the top plate and protrudes from the outer side of the top plate. The inner wall surface of the clamping member is provided with a clamping groove for the arc-shaped flange to be inserted and accommodated.

[0010] As described above, the automatic cleaning device for the crystallization plate of an aero-engine blade casting furnace of this utility model has the following beneficial effects: When using the automatic cleaning device for the crystallization plate of the aero-engine blade casting furnace of this utility model, a scouring pad is placed on the bottom surface of the chassis, and then the periphery of the scouring pad is folded upwards and clamped between the top surface of the chassis and the bottom surface of the cover plate. The movement of the robotic arm and the clamping component is controlled, and the clamping component opens and clamps the cleaning mechanism. The robotic arm drives the clamping component and the cleaning mechanism to move to the position of the crystallization plate for wiping. In this application, by setting a spring, which is installed on the guide rod, a spring preload is provided. When using this cleaning device to wipe the crystallization plate, the device is firmly attached to the surface of the crystallization plate. At the same time, the spring deformation produces a certain amount of extension and contraction, making this cleaning device a flexible device rather than a rigid device, preventing damage to the crystallization plate when the device is excessively pressed against the crystallization plate.

[0017] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show components related to this utility model and are not drawn according to the actual number, shape, and size of the components in the actual implementation.

[0018] like Figure 1-4 As shown, this embodiment provides an automatic cleaning device for the crystallization plate of an aero-engine blade casting furnace. The automatic cleaning device 10 includes a robotic arm 11, a clamping member 12 installed at the end of the robotic arm 11, and a cleaning mechanism 13 that can be clamped on the clamping member 12. The cleaning mechanism 13 includes a base 14, a scouring pad 15 placed on the bottom surface of the base 14, a cover plate 16 placed on the top surface of the base 14 and used to clamp the periphery of the scouring pad 15, and a plate that is vertically fixed to the top surface of the base 14. The device includes at least one guide rod 17, a top plate 18 movably disposed at the top of the guide rod 17 and clamped by the clamping member 12, a vertical hole through which the guide rod 17 can pass, a boss 19 protruding from the outer wall of the guide rod 17 in the middle, a spring 20 between the boss 19 and the top plate 18, the spring 20 being sleeved on the guide rod 17, and a locking nut 21 at the top of the guide rod 17 for locking the guide rod 17 and preventing the guide rod 17 from passing through the vertical hole.

[0019] When using the automatic cleaning device for the crystallization plate of the aero-engine blade casting furnace of this utility model, a scouring pad 15 is placed on the bottom surface of the base plate 14, and then the periphery of the scouring pad 15 is folded upwards and clamped between the top surface of the base plate 14 and the bottom surface of the cover plate 16. The robotic arm 11 and the clamping member 12 are moved, and the clamping member 12 opens and clamps the cleaning mechanism 13. The robotic arm 11 drives the clamping member 12 and the cleaning mechanism 13 to move to the position of the crystallization plate for wiping. In this application, by setting a spring 20, which is installed on the guide rod 17, a preload of spring 20 is provided. When using this cleaning device 10 to wipe the crystallization plate, the device is firmly attached to the surface of the crystallization plate. At the same time, the deformation of the spring 20 produces a certain amount of extension and contraction, making this cleaning device 10 a flexible device rather than a rigid device, preventing damage to the crystallization plate when the device is excessively pressed against the crystallization plate.

[0020] Specifically, the top of the guide rod 17 is provided with an external thread that can be screwed into the locking nut 21. When locked to the top, the preload of the spring 20 can be adjusted by adjusting the locking nut 21.

[0021] The flange 22 is fixedly connected to the top plate 18 by the first bolt 23. The top end of the spring 20 elastically abuts against the flange 22, and the bottom end of the spring 20 elastically abuts against the boss 19.

[0022] Specifically, the chassis 14 and the cover plate 16 are fixedly connected by the second bolt 24. The scouring pad 15 is folded up along the periphery of the chassis plate and then sandwiched between the top surface of the chassis 14 and the bottom surface of the cover plate 16.

[0023] To better clamp the top plate 18, an arc-shaped flange 25 is provided on the outer side wall of the top plate 18. The arc-shaped flange 25 surrounds the outer side wall of the top plate 18 and protrudes from the outer side of the top plate 18. The inner wall surface of the clamping member 12 is provided with a clamping groove for the arc-shaped flange 25 to be inserted and accommodated.

[0024] When the clamping member 12 clamps the top plate 18, the arc-shaped flange 25 is inserted into the clamping groove, which can prevent the cleaning mechanism 13 from detaching from the clamping member 12 under the action of gravity, thus achieving a better clamping effect.

[0025] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
