Detailed Description
the present invention will be described in detail below with reference to embodiments shown in the drawings. The present invention is not limited to the embodiment, and structural, methodological, or functional changes made by one of ordinary skill in the art according to the embodiment are included in the scope of the present invention.
fig. 2 to 4 show a preferred embodiment of the present invention. The grinding stone 100 provided by the invention is used for cleaning the end surface 21 of the high-temperature pressure head 20 and comprises a base 11 and a plurality of cleaning parts 12 formed on the surface of the base 11. Specifically, the grinding stone 100 is mounted on a machine table below the high-temperature pressure head 20, and then is subjected to back-and-forth relative reciprocating friction with the end face 21 of the high-temperature pressure head 20, so that the jelly or other impurities adhered to the area to be cleaned of the end face 21 are removed. Generally, the area to be cleaned is located in the center of the end surface 21.
The cleaning part 12 is transversely arranged with a gap and is formed with a first groove 13, the transverse width of any cleaning part 12 along the end surface 21 is smaller than the width of the end surface 21, and when the cleaning part 12 contacts with the area to be cleaned of the end surface 21, the end surface 21 is positioned above the first groove 13 or outside the grinding stone 100 along the transverse side edge. Therefore, when the cleaning part 12 and the end face 21 are subjected to relative movement and friction back and forth, the side face 22 of the high-temperature pressure head 20 is not contacted with the grinding stone 100, so that the side friction force generated by mutual friction between the side face 22 and the grinding stone 100 in the cleaning process is avoided, the interaction force between the end face 21 and the grinding stone is ensured, and the effective cleaning of the end face 21 is ensured.
The cleaning part 12 has two side walls 121 formed in two adjacent first grooves 13 and disposed oppositely, and a top wall 122 facing the high temperature head. The junction of the side wall 121 and the top wall 122 is further formed with a chamfered surface 123 to prevent the top corner of the cleaning portion 12 from collapsing under stress during working. The chamfer surface 123 is a slope or an arc surface.
The cleaning part 12 is further formed with a second groove 14 recessed downwards from the top wall 122, and the second groove 14 is used to enhance the local friction force between the top wall 122 and the area to be cleaned, so as to effectively overcome the problem that the conventional grinding stone 10 has a smoother surface and makes the firmly adhered jelly difficult to remove.
In the present embodiment, the grindstone 100 has a rectangular block shape. The second grooves 14 are connected to the two first grooves 13 on both sides of the corresponding cleaning part 12 in the lateral direction and are perpendicular to the first grooves 13. Further, since the cleaning portion 12 receives a large stress in the front-rear direction, the depth of the second groove 14 is smaller than the depth of the first groove 13. In order to achieve the above object, in other embodiments of the present invention, the second grooves 14 may be disposed along a direction deviating from the front-back direction, or may be disposed discontinuously.
the invention also provides a cleaning device with the grinding stone 100, and the cleaning device also comprises a driving mechanism 30 for driving the high-temperature pressure head 20 to reciprocate back and forth relative to the grinding stone 100.
the invention also provides a cleaning control method of the cleaning device, which comprises the following steps: mounting a grinding stone 100;
the transverse relative position of the grinding stone 100 and the high-temperature pressure head 20 is adjusted through the driving mechanism 30, so that a certain set cleaning part 12 is positioned below the high-temperature pressure head 20 and aligned with the area to be cleaned of the end surface 21 along the front-back direction;
Adjusting the height of the high temperature ram 20 so that the predetermined cleaning portion 12 is in contact with the end face 21;
And starting the driving mechanism 30, and accumulating the reciprocating operation time length or the reciprocating operation times of the high-temperature pressure head 20 or the grinding stone 100 until the preset time length t or the preset reciprocating operation times n is reached to finish the cleaning operation.
In another embodiment of the present invention (not shown), the grinding stone 100 has a cylindrical shape, the axial line thereof is disposed transversely, and the first grooves 13 are annularly formed on the cylindrical surface of the grinding stone 100. Accordingly, the cleaning apparatus also has a driving motor for driving the grinding stone 100 to rotate.
In summary, with the grinding stone 100, the cleaning apparatus and the cleaning control method of the present invention, the base 11 facilitates the installation of the grinding stone 100 and enhances the strength of the supporting structure of the cleaning part 12; the cleaning part 12 can perform friction cleaning on an area to be cleaned of the end face 21 of the high-temperature pressure head 20, and eliminate friction acting force between the grinding stone 100 and the side face 22 of the high-temperature pressure head 20, so that the end face 21 of the high-temperature pressure head 20 is effectively cleaned, and normal production is guaranteed.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
