Description

Technical Field

[0001] The utility model relates to the field of metallurgical production, in particular to an automatic feeding mechanism for metallurgical powder. Background Art

[0002] In the production process of commonly used alloys in aerospace, the alloy powder is first added to the grinding material in the tank and rotated and ground. After grinding, the fine metallurgical powder and the grinding material need to be separated. In the meantime, the mixture of the metallurgical powder and the grinding material needs to be poured out from the tank, which is also called metallurgical powder unloading. In the existing production, the tank is manually lifted and turned over for unloading. Because the metallurgical powder after grinding is extremely small, some reaches the micron level, dust is easily generated during the manual unloading process, resulting in pollution of the production environment. Even if the workers wear protective equipment during operation, being in this environment for a long time is also harmful to the health of the workers. Therefore, in order to ensure the safety of workers and the air quality in the production area, it is a more urgent issue to propose a working mechanism for automatically dumping metallurgical powder.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] As shown in the figure, an automatic unloading mechanism for metallurgical powder includes a support frame 1, and three unloading stations 2 are located above the support frame 1. The middle of the unloading station 2 is hollowed out as a channel for pouring metallurgical powder downward. The unloading station 2 includes a slide 21, and the slide 21 is used to transport the metallurgical powder tank. Two limit rods 22 are arranged at parallel intervals on both sides of the slide 21. The limit rods 22 are used to ensure that the tank does not roll sideways and can move forward along the slide 21. The unloading station 2 also includes a support plate 23, which is located in front of the side of the slide 21, and the support plate 23 and the slide 21 are fixedly connected to the support frame 1; there is a material receiving component under the unloading station 2 for collecting the dumped metallurgical powder; the clamping mechanism 3 includes a frame 31 and a lower clamp 32, and an upper clamp 33 is arranged opposite to the lower clamp 32, and the front end of the lower clamp 32 contacts and connects to the rear end of the slide 21, and a cylinder 34 is arranged on the outside of one side of the frame 31 on which the upper clamp 33 is installed, and the output end of the cylinder 34 passes through the frame 31 and is connected to the top of the upper clamp 33, and the frame 31 is open on one side, and the open side is a tank body inlet 35, and the tank body slides into the frame 31 from the tank body inlet 35, and the side opposite to the tank body inlet 35 is the frame side 36 A pressure sensor 37 is installed at the edge of the frame side 36. The pressure sensor 37 is used to check whether the tank body fits with the frame side 36. A round hole 38 matching the size of the tank body opening is provided in the center of the frame side 36. The round hole 38 is used to be sleeved on the outside of the tank body opening and tightly fit; a rotating mechanism 4 is provided on both sides of the frame 31. The rotating mechanism 4 includes a bearing 41. The bearing 41 is fixedly arranged on the support plate 23. The output end of the rotating motor 42 is connected to the side of the frame 31 through the bearing 41. The rotating motor 42 drives the clamping mechanism 3 to rotate counterclockwise, and the cylinder 34 pushes the upper clamping jaw 33 to move downward. The upper clamping jaw 33 cooperates with the lower clamping jaw 32 to clamp the tank body, thereby driving the tank body to rotate counterclockwise.

[0020] In order to realize full-process automatic unloading, the automatic unloading mechanism for metallurgical powder should be coordinated with the robot gripper. When in use, the robot gripper lifts the tank body vertically, and then the robot rotates the tank body 90 degrees counterclockwise to make the tank body horizontal, and the opening of the tank body faces the automatic unloading mechanism for metallurgical powder. The robot gripper first places the tank body on the slide 21, and then pushes the bottom of the tank body with the gripper. A pressure sensor 37 is provided on the outside of the side 36 of the frame to check whether the tank body is in place. After the tank body is in place, it will contact the pressure sensor 37. The pressure sensor 37 sends a signal to the cylinder 34. The cylinder 34 receives the in-place signal and pushes the upper clamp 33 downward, thereby clamping the tank body. At the same time, the pressure sensor 37 also sends a signal to the robot, and the robot retracts the gripper, and then performs the actions of taking the tank body, rotating the tank body, placing the tank body, and pushing the tank body before the next unloading station 2.

[0021] The rotating motor 42 drives the clamping mechanism 3 to rotate 90 degrees counterclockwise. The tank body opens downward as the clamping mechanism 3 rotates 90 degrees counterclockwise. The metallurgical powder is poured into the receiving component at the lower end. At this time, there is still metallurgical powder remaining in the tank body. The rotating motor 42 drives the tank body to swing. The swinging direction is 45 degrees to 45 degrees to the left and right from the vertical direction. After repeated swinging several times, the metallurgical powder in the tank body is completely discharged. At this time, the tank body opening is vertically downward. The rotating motor 42 is controlled to drive the tank body to rotate 90 degrees clockwise. The tank body is placed horizontally on the unloading station 2. The cylinder 34 drives the upper clamp 33 to move upward. The upper clamp 33 is separated from the tank body. The robot gripper first pulls the emptied tank body outward onto the slide 21, and then clamps the tank body and puts it back into the empty tank body collection area.

[0022] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
