Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The embodiment provides a polishing treatment device in a narrow space, which has the structure shown in fig. 1, 3 and 4, is in an elongated cylindrical shape and consists of a main body 2, an extension rod 4, a vibration polishing head 5 and a vibration motor 8. Main part 2 is cylinder or centrum structure, and extension rod 4 fixed connection is at the head of main part 2, and extension rod 4 is the cylinder or the centrum structure that the external diameter is less than main part 2, and the head at extension rod 4 is installed to vibration head 5, and vibrating motor 8 is installed in the middle of main part 2 through loosening bolt 9.
In order to ensure the strength and effectiveness of vibration transmission, the main body 2 and the extension rod 4 are formed by cutting a whole 40Cr bar, the length of the extension rod 4 ranges from 50mm to 200mm according to different specifications, and the diameter of the extension rod is 8 mm.
The vibration motor 8 is fixed in the main body 2 of the device through the anti-loosening bolt 9 and is connected with a power supply through the wire 1, so that the whole device is driven to vibrate. A groove is formed at the top of the main body 2, and the vibration motor 8 is installed in the groove. After the power is switched on, the vibration motor 8 starts to vibrate in high frequency and micro amplitude, and the rated rotating speed of the motor is 14000 RPM.
The vibration polishing head 5 is formed by sintering hard alloy powder and can be detached or welded at the head of the extension rod 4. This embodiment has adopted the welding mode, because the thin diameter of extension rod only has 8mm, adopts detachable construction easily not hard up and influence the transmission of vibration. If the grinding head is broken or damaged, the grinding head is cut off and a new grinding head is welded.
In order to adapt to different working conditions, the vibration polishing head 5 can be designed into two shapes of a cylinder and a flat shape. The cylindrical vibration polishing head 6 is suitable for narrow spaces such as pipelines with small pipe diameters, and the flat vibration polishing head 7 is suitable for narrow spaces such as small closed impellers which are large in inner area and smooth. The overall diameter of the cylindrical vibration polishing head 6 is 12mm, and the length is 50 mm; the flat vibration polishing head 7 has an overall thickness of 12mm, a length of 50mm and a width of 30 mm.
As shown in fig. 2, the vibration polishing head 5 includes a base and a vibration plate formed in a strip shape, the base is used for being connected with the extension rod 4, the plurality of strip-shaped vibration plates are parallel to each other but not in contact with each other, each vibration plate is 3mm wide and 2mm thick, and a gap between adjacent vibration plates is not more than 2 mm. The surface of the vibrating piece is provided with a block of bulges, and the interval between every two adjacent bulges is not more than 8 mm. Cylindrical structure is constituteed to a plurality of tremblers of cylindrical vibration head 6, and cuboid structure is constituteed to a plurality of tremblers of flat vibration head 7, and the object that can also polish as required is different, sets up to the vibration head 5 of different shapes. When the whole device vibrates, the amplitude of the vibration polishing head 5 is amplified due to the existence of the vibrating sheet, so that the surface needing to be treated can be effectively knocked and collided, and the polishing effect is achieved.
The middle part of the main body 2 is wrapped with a layer of damping rubber 3 with the thickness of 3mm, and the material of the damping rubber is NR natural rubber. After the device starts, the 3 positions of the damping rubber are held by hands, so that the impact on the hands can be well relieved.
When the vibration polishing head is used, the proper polishing head 5 is selected according to the shape of a part to be polished, then the power supply is switched on, and the vibration polishing head is placed at the part to be polished to start polishing. As shown in FIG. 5, a small enclosed impeller is ground, a flat grinding head 7 is selected, and then the cushion rubber portion 3 is held by hand to turn on the device. After the power supply is switched on, the vibration polishing head 5 extends into the impeller flow channel to be polished, and then the polishing head 5 is tightly attached to the surface of the base body to start polishing. The polishing head 5 vibrates in high frequency and continuously knocks and collides, and coating rusts and the like on the surface of the substrate are removed along with the high frequency and the collision to form certain roughness. After the observation reaches the treatment effect, the power supply can be turned off and the device can be taken out.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
