Embodiment 1

[0066] Example 1: A three-dimensional profiling and edging machine for automobile rearview mirrors

[0067] Such as Figure 1-1 to Figure 1-3 As shown, the three-dimensional profiling and edging machine for automobile rearview mirror includes a machine tool part, a pneumatic transmission control part, a fixed-axis rotating part, a rotating part and a cooling liquid adding part;

[0068] Among the above 5 components, the pneumatic transmission control part is a mature technology and need not be repeated. The coolant addition part is mainly to cool the workpiece during the grinding process, including the water pump 31 (not shown in the figure), the nozzle 32, and the sewage pipe 33- and the coolant water tray installed under the workbench are also mature technologies, which are not shown in the figure and will not be repeated here.

[0069] Combine below Figure 1-1 to Figure 1-3 The difference in structure between the three-dimensional profiling and edging machine for automobil...

Embodiment 2

[0081] Embodiment 2: A method for three-dimensional edging of automobile rearview mirrors.

[0082] The method adopts the three-dimensional profiling and edging machine for automobile rearview mirror described in Embodiment 1, and uses a cam-like mechanism composed of a similar cam 15, a fixed support 14 and a sliding part 16 to achieve simultaneous completion of the automobile rearview mirror at one time. The three-dimensional edging method, the cam-like 15 is an arc-shaped cylinder with different heights, the bottom of the arc-shaped cylinder is flat, and the top is the integral contour part I1501, the working part 1502, the transition part 1503 and the contour part II 1504, the contour part I 1501 and the contour part II 1504 are planes, the working part 1502 and the transition part 1503 are arc surfaces; Rotation center axis P3 coincides, and slide piece 16 is fixed on the bottom of swing arm 9, and quasi-cam 15 is fixed on machine tool bed 1 with the fixed center axis P3 ...

Abstract

An automobile rear-view mirror three-dimension profiling edge grinding machine comprises a machine tool, a pneumatic transmission control part, a fixed-axis rotation part, a rotation part and a cooling liquid addition part. The fixed-axis rotation part comprises a motor II, a cycloid needle wheel type reducer, a profiling, a locating profiling, an upper rubber base and a lower rubber base, wherein the motor II is connected with the cycloid needle wheel type reducer, drives the profiling, the locating profiling and the lower rubber base to rotate around a fixed shaft through a gear, and drives a workpiece which is clamped between the upper rubber base and the lower rubber base to rotate around the fixed shaft. The rotation part comprises a motor I, a rocker arm, a grinding wheel, a guide wheel mechanism, a cam-type mechanism and an elastic air cylinder, wherein the cam-type mechanism is circular-arc-shaped cylinders with different heights, and the circular-arc central axis of the circular-arc-shaped cylinders and the rotation center of the rocker arm coincide when the circular-arc-shaped cylinders are installed. When the profiling rotates by a circle, the rocker arm swings one time back and forth at the left-right limit position, the included angle theta between the rocker arm and the AO direction finishes a periodic change, the rotating workpiece G is wrapped for one circle by the grinding wheel, and the three-dimension grinding machining of an automobile rear-view mirror is finished.

Description

technical field [0001] The invention relates to a profiling numerical control grinding machine, in particular to a profiling and edging machine for automobile rearview mirrors. Background technique [0002] Car rearview mirror is an important safety part of the car. It is a device that enables the driver to indirectly see the rear, side and lower positions of the car. However, the thickness of the glass of the rearview mirror is only 1.2-2mm. After being formed into a lens, The entire surface is a curved surface, and the edge to be ground is a curved edge, that is, the edge grinding and chamfering of the three-dimensional space curve profile of the rearview mirror glass; when grinding, the direction of the grinding force and clamping force is easy to make the lens Cracking, while edging should be done at the same time as chamfering. [0003] There are three main methods for processing automobile rearview mirrors: [0004] 1. Manual edging [0005] Manual edging relies on ...
