[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0042] Example 1:
[0043] like Figure 1 As shown, this utility model discloses a porous copper grinding block, including a grinding block body 1, a connecting component 2, and a flexible pad 3. The main components of this utility model will be described in detail below:
[0044] like Figure 1 As shown, the two opposite surfaces of the grinding block body 1 are both grinding working surfaces; four positioning holes 11 are arranged at equal intervals along a straight line on the grinding working surface. The positioning holes 11 are through holes that penetrate the grinding block body 1, and the hole diameters of the positioning holes 11 are the same and their central axes are parallel to each other.
[0045] like Figure 1 and Figure 2 As shown, both ends of the through-hole structure are chamfered 11a to facilitate quick alignment and insertion of the connector and to prevent the sharp edges of the through-hole structure from affecting the grinding and polishing operation.
[0046] like Figure 1 As shown, the connecting assembly 2 includes a connecting rod 21 and two connectors 22 disposed at one end of the connecting rod 21. The two connectors 22 can simultaneously form a detachable plug-in fit with the two positioning holes 11. The projection direction of the connecting rod 21 on the grinding block body 1 coincides with the arrangement direction of the positioning holes 11. The front end of the connector 22 is a spherical structure with a radius of curvature of R. The diameter of the positioning hole 11 is d, and 0.5d < R ≤ d, allowing the connecting rod 21 and the grinding block body 1 to deflect within a certain angle, making the grinding process more stable and allowing the grinding block body and the workpiece to make complete contact grinding, resulting in a smoother surface of the ground workpiece. The connecting rod 21 has a bent structure, and the angle between its input end axis and its output end axis is not less than 90°.
[0047] like Figure 1As shown, the flexible gasket 3 is a pressure-sensitive adhesive sheet with a pressure-sensitive adhesive layer, which is detachably arranged between the connecting head 22 and the positioning hole 11.
[0048] As shown in Figure 1 and Figure 2 The use method and principle of the utility model are described as follows.
[0049] The connecting head 22 is aligned with the positioning hole 11, and the flexible gasket 3 is placed therebetween, and then the connecting head 22 is connected to the positioning hole 11 through the flexible gasket 3, in the process, the pressure-sensitive adhesive layer is extruded and adhered to the connecting head 22 and the positioning hole 11, so that the connecting head 22 and the positioning hole 11 are not easily separated;
[0050] When the two connecting heads 22 are connected with the positioning hole 11, the projection direction of the connecting rod 21 on the grinding block body 1 coincides with the arrangement direction of the positioning hole 11, so that the grinding block body 1 can extend into the narrow space on the mold for grinding work, and the two-point connection can avoid the deflection of the grinding block body 1 during the processing;
[0051] The connecting rod 21 connects the grinding equipment, and the grinding agent is applied on the mold processing surface, and after the equipment is started, the grinding block body 1 drives the grinding agent to perform friction cutting processing on the mold processing surface; in the process, when the grinding block body 1 passes through the grinding agent accumulation position, the positioning hole 11 gathers and adsorbs the excess grinding agent in the hole, and when it passes through the grinding agent thin place, the grinding agent in the positioning hole 11 flows out to coat and supplement it, so as to ensure the uniformity of the distribution of the grinding agent during the grinding work;
[0052] At the same time, the double working surfaces of the grinding block body 1 can be alternately used, and after single-side wear, the grinding block body 1 can be turned over for continuous work. It should be noted that the grinding block body 1 is a carrier, and the grinding agent plays a cutting role.
[0053] Embodiment two:
[0054] As shown in Figure 1 and Figure 3 The difference between the embodiment and the embodiment one is that the projection direction of the connecting rod 21 on the grinding block body 1 is perpendicular to the arrangement direction of the positioning hole 11, which is suitable for grinding the curved surface and large surface of the mold.
[0055] Finally, it should be pointed out that the above is only a preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
