Embodiment 1

[0021] combine figure 1 , figure 2 , image 3 and Figure 4 , a conical spiral grinding device, comprising a frame base 4, a grinding disc 1, a workpiece feed mechanism and a workpiece mounting head 6, the workpiece mounting head 6 is bonded to the grinding disc 1, and the grinding disc 1 disc body is conical and spiral, The abrasive particle size on the surface of the grinding disc changes in a gradient manner with the helix of the disc body, the closer to the top of the cone helix, the higher the abrasive particle size; the workpiece on the workpiece mounting head 6 stays at different positions for different times, and the abrasive particle size is also different , the machining accuracy will be different. Because the workpiece is processed from the bottom of the conical spiral grinding disc, the abrasive grain size at the bottom of the conical spiral is the lowest, so the rough grinding can be started at the beginning, and the higher the precision of the processing is, ...

Embodiment 2

[0028] This embodiment is basically consistent with the solution of Embodiment 1, the only difference is that the workpiece mounting head 6 bottom surface is provided with a workpiece mounting hole, the workpiece is installed in the workpiece mounting hole, and there are multiple workpiece mounting holes, which are evenly distributed on the workpiece mounting head. on the underside. This mode can process multiple workpieces at the same time, which further improves the processing efficiency.

Abstract

The invention relates to a cone spiral grinding device which comprises a machine frame base, a grinding disc, a workpiece feeding mechanism and a workpiece mounting head. The workpiece mounting head is attached with the grinding disc. A disc body of the grinding disc is in a cone spiral shape. The abrasive grain on the disc face of the grinding disc changes according to the spiral line of the disc body in a gradient modem. The abrasive grain is high close to the top end of the cone spiral line. The workpiece mounting head is directly connected with a motor. The motor controls rotating of the workpiece mounting head. The workpiece feeding mechanism can control the workpiece mounting head to move along a cone spiral track. Under the common effect of rotating of the cone spiral grinding disc and rotating of the workpiece mounting head, disordering of machined lines on a surface to be machined can be achieved, and accordingly machining efficiency and quality are improved. Meanwhile, the cone spiral grinding device is simple and compact in structure, low in cost and high automation degree, and by controlling the abrasive grain of different parts of the grinding disc, workpieces can be machined in different accuracy degrees.

Description

technical field [0001] The invention relates to a conical spiral grinding device, which is suitable for grinding and polishing the surfaces of workpieces such as optical elements and amorphous film substrates. Background technique [0002] Grinding is the use of abrasive particles coated or pressed on the grinding tool to finish the processing surface (such as cutting) through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metal materials. The processed surface shapes include plane, inner and outer cylindrical and conical surfaces, convex and concave spherical surfaces, threads, tooth surfaces and other profiles. The processing accuracy can reach IT5~01, and the surface roughness can reach Ra0.63~0.01 microns. [0003] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface....
