Description

Technical Field

[0001] The utility model relates to the technical field of diamond grinding brushes, in particular to a reciprocating diamond grinding brush. Background Art

[0002] When grinding, the diamond grinding brush may cause eccentric grinding due to the grinding angle, that is, the grinding surface of the grinding brush is no longer flat, which reduces the grinding effect of the grinding object during reciprocating grinding. The grinding head on the traditional grinding brush that contacts the grinding object is usually a non-detachable structure, which makes it difficult to flexibly replace a certain grinding surface of the grinding brush. Utility Model Content

[0003] The utility model provides a reciprocating diamond grinding brush, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] A reciprocating diamond grinding brush comprises a base and a plurality of diamond grinding heads. The base is detachably connected to the diamond grinding heads via a connecting assembly. A connecting port is arranged at the center of the base. The connecting assembly comprises a base plate, a connecting hole, a mounting port, a clip and a screw. A groove and a connecting hole for mounting the base plate are arranged on the base. The connecting hole is connected to the groove. A connecting tube is arranged on the back side of the base plate. The base plate is positioned and mounted on the base via the connecting tube. The clip is nested with the connecting tube. The screw passes through the clip and is threadedly connected to the connecting tube. The clip is mounted on the mounting port.

[0006] The base plate and the diamond grinding head are combined to form a modular component of a complete grinding surface area, which can be disassembled and replaced according to the use requirements. The base plate is first positioned and installed in the connection hole on the base through the connecting tube, and then the buckle is buckled into the outside of the connecting tube. The screw passes through the buckle and is threadedly connected to the connecting tube. At this time, the base plate is locked on the base.

[0007] A preferred technical solution: a protrusion is provided on the side end of the buckle, and the buckle is made of elastomeric plastic.

[0008] The fastener and the mounting port can be in a fixed fitting state, that is, the material of the fastener can give it a certain deformation space. After the fastener is installed in the mounting port, the protrusion at its side end will fully contact the side of the mounting port, thereby improving the fixing effect of the fastener. When the fastener is nested with the outer surface of the connecting tube, the limiting effect on the base plate is also improved to a certain extent.

[0009] A better technical solution: The installation opening is provided with a notch for limiting the displacement of the protrusion, so as to facilitate knowing whether the fastener is installed in place during installation.

[0010] A preferred technical solution: A connecting block adapted to the base plate is provided at the side end of the diamond grinding head, and a colloid is usually used to connect one side of the connecting block to the base plate.

[0011] A preferred technical solution: a plurality of bristles are connected to the base plate, and the grinding surface can be composed of the bristles.

[0012] A better technical solution: the diamond grinding head is arranged in a ring shape on the base.

[0013] A preferred technical solution: The horizontal cross section of the diamond grinding head is a trapezoidal structure.

[0014] A preferred technical solution: the connecting tubes are arranged at both ends of the base plate.

[0015] A better technical solution: a rubber cover is installed and located outside the screw.

[0016] A preferred technical solution: The head of the screw is set to a cross hole, a slotted hole or a hexagonal hole. Of course, it can also be replaced with other shapes to facilitate rapid installation with corresponding tools.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] The diamond grinding head used for grinding in the utility model is detachable, and can be replaced in a targeted manner when a certain area is worn unevenly, so as to ensure that the grinding effect is maintained during the reciprocating grinding of the grinding equipment. The diamond grinding heads arranged in different areas form a modular assembly and can be replaced independently. BRIEF DESCRIPTION OF THE DRAWINGS
