Description
Technical Field
The invention relates to a cleaning tool, in particular to an elastic brush for cleaning the inner wall of a cylindrical part.
Background
After the cylindrical part is subjected to heat treatment and mechanical processing, dirt such as oil stain or spot stain and the like which is contaminated in the processing process can be left on the inner wall of the part, the surfaces of the inner wall and the outer wall of the part need to be cleaned and wiped clean before the subsequent process is carried out, the cleaning is very easy for the outer surface of the part aiming at the cylindrical part with the total length of more than 900mm and the diameter of less than phi 93mm, but the inner wall can not be directly contacted by a palm, and only the cleaning work can be carried out by means of a tool.
There is an elasticity cleaning device at present, and the device can make cotton and a section of thick bamboo inner wall fully contact, and the filth clearance effect such as greasy dirt, the spot stain of inner wall is showing, and the device includes action bars, spring leaf, cylindric lock and swing piece, along the even fixed mounting spring leaf of circumference on the action bars, the one end fixed connection of spring leaf is on the surface in action bars middle section, and the other end of spring leaf passes through cylindric lock and swing piece fixed connection, and the winding has the cotton on the surface of swing piece.
Because the spring piece is connected with the swinging block through the cylindrical pin, the swinging block is required to be in clearance fit relative to the cylindrical pin after connection, and therefore the swinging block is easy to separate and needs to be reassembled again when the tool is used. Because the spring piece has certain elasticity, when the cylindrical pin is installed, the spring piece is not easy to insert into the circular hole of the swinging block, the assembly time is long, the repeated operation is carried out, and the product quality and the production efficiency are influenced.
Disclosure of Invention
In view of this, the present invention provides a quick-change elastic brush, which can realize a single reliable connection between a spring piece and a swing block without affecting the swing flexibility of the swing block.
A quick-change elastic brush comprises a spring piece, a swinging block, a bolt and a nut;
the spring piece is provided with an arc-shaped concave structure which penetrates through the whole spring piece along the width direction of the spring piece;
the swing block is provided with an open through groove, and bolt holes are machined in the side walls of two sides of the through groove;
the spring piece is arranged in the through groove of the swinging block, the bolt penetrates through the two bolt holes in the swinging block and then is fixed with the nut, the part of the bolt in the through groove of the swinging block is matched with the concave structure of the spring piece and limits the spring piece to be separated from the swinging block along the length direction of the through groove, and the swinging block has the freedom degree of moving along the axial direction of the bolt and rotating around the central axis of the bolt relative to the spring piece.
Further, the width dimension of the spring piece is smaller than the width of the swing block through groove, so that the swing block has the freedom degree of moving along the axial direction of the bolt relative to the spring piece.
Further, a gap is reserved between the spring piece and the bottom surface of the through groove of the swinging block, so that the swinging block has the freedom degree of rotating around the central axis of the bolt relative to the spring piece.
Further, the diameter of the bolt is smaller than the inner diameter of the assembly hole of the swinging block, and the nut cannot be locked with the swinging block.
Furthermore, the surface of the swinging block is an arc-shaped surface, and grooves which are parallel to each other are processed on the arc-shaped surface.
Has the advantages that:
1. according to the invention, the arc-shaped recessed structure on the spring piece and the hexagon bolt are matched and arranged in the through groove on the swing block, the swing block and the spring piece are firmly connected and flexibly swing, the phenomenon of releasing the swing block is not generated, the product only needs to be assembled once, the problem of repeated assembly of parts is avoided, and when the parts are scrapped, new parts are disassembled and replaced, so that the parts can be conveniently and quickly connected and replaced, and the tool operability and the production efficiency are obviously improved.
2. The surface of the oscillating block is designed to be an arc-shaped surface, and the parallel grooves are processed on the arc-shaped surface, so that the oscillating block can be in line contact with the inner wall of the cylinder, and the grooves can temporarily retain oil stains and impurities falling off in the cleaning process, thereby being beneficial to improving the cleaning efficiency.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
As shown in fig. 1 and 2, the invention provides a quick-change type elastic brush, which comprises a spring piece 4, a swinging block 1, a bolt 2 and a nut 3.
As shown in fig. 1, the spring plate 4 is a sheet structure with equal width and bent twice, the bent spring plate 4 is regarded as being composed of three sections, the first section and the last section are parallel to each other, the middle section is naturally connected with the first section and the last section, one bent part is provided with an arc-shaped concave structure, and the concave structure penetrates through the whole spring plate 4 along the width direction of the spring plate.
As shown in fig. 2, the swing block 1 has an open through slot, and bolt holes are machined on the side walls of both sides of the through slot.
The spring piece 4 is arranged in the through groove of the swinging block 1, the bolt 2 penetrates through two bolt holes on the swinging block 1 and then is fixed with the nut 3, the diameter of the bolt 2 is smaller than the inner diameter size of an assembly hole of the swinging block 1, and meanwhile, the nut 3 cannot be locked with the swinging block 1. The part of the bolt 2 in the through groove of the swing block is matched with the concave structure of the spring piece 4 and limits the spring piece 4 to be separated from the swing block 1 along the length direction of the through groove, and the swing block 1 has the freedom degree of moving along the axial direction of the bolt 2 and rotating around the central axis of the bolt 2 relative to the spring piece 4.
The width dimension of the spring piece 4 is smaller than the width of the through groove of the swing block 1, so that the swing block 1 has a degree of freedom of movement in the bolt axial direction with respect to the spring piece 4.
As can be seen from fig. 1, a small gap is left between the first section (from the arc-shaped concave structure to the top end of the spring piece) of the spring piece 4 and the bottom surface of the through groove of the swing block 1, so that the swing block 1 can rotate counterclockwise by an angle around the central axis of the bolt 2, and the middle section (from the arc-shaped concave structure to the other bending part of the spring piece) of the spring piece 4 inclines by an angle, so that the gap between the section and the bottom surface of the through groove of the swing block 1 is large, and therefore the swing block 1 can rotate clockwise by a large angle around the central axis of the bolt. It can be seen that, after the swing block 1 is connected with the spring plate 4 in the above manner, the swing block 1 has a very flexible degree of freedom, which is not only convenient for installation and replacement, but also beneficial to improving the cleaning performance of the elastic brush.
In addition, the surface design of swing piece 1 is the arcwall face (the plane in the figure), and the processing has the recess that is parallel to each other on the arcwall face, and the winding has cotton on the surface of swing piece 1, utilizes the cotton to be used for cleaning cylindric part inner wall.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
