Description

Technical Field

[0001] This utility model relates to the field of soft abrasive pad technology, and in particular to a soft abrasive pad that can be bent to fit irregular surfaces. Background Technology

[0002] Soft grinding discs are tools used for precision grinding and polishing, and their structural design directly affects the processing effect and the scope of application.

[0003] While existing soft grinding discs can conform to the irregular surfaces of workpieces due to their structural characteristics, they cannot perform grinding and polishing effectively when the irregular surfaces have conical protrusions. Utility Model Content

[0004] The purpose of this invention is to provide a flexible abrasive sheet that can be bent to fit irregularly shaped surfaces in order to solve the above-mentioned problems.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a flexible grinding disc that can be bent to fit irregular surfaces. Its structure includes a positioning ring, a flexible substrate, an elastic connecting disc, and a grinding mill connector. The flexible substrate is connected to the bottom surface of the positioning ring. The elastic connecting disc is horizontally positioned on the upper part of the inner ring of the positioning ring. The grinding mill connector is located at the center of the upper end face of the elastic connecting disc for connecting to a grinding mill. The positioning ring has a bending gap at both its front and rear ends, allowing it to bend and fold through the two gaps. The top front and rear of the positioning ring have detachable limiting plates that restrict the corresponding bending gaps. A deformation groove is provided on both sides of each bending gap, and an elastic bending positioning plate is fixedly connected to both deformation grooves.

[0006] In the above technical solution, a flexible grinding disc that can be bent to fit irregular surfaces is used, which can adapt to workpieces with various irregular processing surfaces. When the irregular processing surface has a conical protrusion, the restriction on the bending gap is released by removing the elastic bending positioning plate, so that the positioning ring bends, as shown in the figure. When the flexible grinding disc rotates, the bent positioning ring will drive the flexible substrate to form a conical grinding surface structure to ensure that the grinding and polishing of the conical protrusion is in place.

[0007] In one embodiment, in order to conform to the irregular end face of the workpiece during processing, the flexible substrate completely covers the bottom surface of the positioning ring and is made of cotton cloth.

[0008] In one embodiment, to improve the cutting force, an abrasive layer is provided on the end face of the flexible substrate away from the positioning ring.

[0009] In one embodiment, for ease of assembly and disassembly, a fixing bolt is screwed onto each of the left and right ends of the limiting plate, and the two fixing bolts are respectively threaded onto the positioning ring at the left and right positions of the bending gap.

[0010] In one embodiment, in order to enable the left and right parts of the positioning ring to bend symmetrically, the two bending gaps are located on the same axis.

[0011] In one embodiment, in order to connect to the output end of the mill, the mill connector has an internal threaded hole at the center of its top surface.

[0012] In one embodiment, for connection positioning, the elastic bending positioning plate is an arc-shaped structure with the inner and outer rings of the positioning ring as the center.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following: This utility model discloses a flexible grinding disc that can be bent to fit irregularly shaped surfaces. The flexible grinding disc can adapt to workpieces with various irregularly shaped processing surfaces. When the irregularly shaped processing surface has a conical protrusion, the restriction on the bending gap is released by removing the elastic bending positioning plate, so that the positioning ring bends. When the flexible grinding disc rotates, the bent positioning ring will drive the flexible substrate to form a conical grinding surface structure to ensure that the grinding and polishing of the conical protrusion is in place.
