Abstract

The invention discloses an air bag polishing method and device. The air bag polishing method comprises the following steps that an executing mechanism is driven to move towards a to-be-polished workpiece according to a preset included angle and a preset feeding amount; the pressure exerted on the to-be-polished workpiece by the polishing head is obtained; in any two-dimensional plane, according to the preset included angle and the pressure, the actual pressure vertically acting on the to-be-polished workpiece by the polishing head under the current dimension is calculated; obtaining a deviation value between the actual pressure and a preset pressure, wherein the preset pressure is converted from the preset feed amount; and the feeding amount of the executing mechanism is adjusted according to the deviation value. According to the air bag polishing method and device, the problems that due to the fact that the rigidity and movement precision of a robot are not enough, polishing pressure is not stable, the material removal amount is not stable, and surface shape convergence is slow in the polishing process are solved.

Description

technical field

[0001] The invention relates to the technical field of airbag polishing, in particular to a polishing device for an airbag polishing method. Background technique

[0002] As an important polishing technology, airbag polishing has been widely used in the field of optical precision polishing. The traditional airbag polishing technology requires a five-axis precision machine tool to control the position and attitude of the polishing head to achieve the transformation of the full degree of freedom in space, resulting in non-standard machine tools. The structure is complex and the cost is high. The robot controls the airbag polishing head and the flexible polishing head to polish optical components, which has been applied more and more. Using the robot's spatial movement and six degrees of freedom full coverage function, it can control the spatial position of the polishing head to change arbitrarily. At the same time, the robot belongs to commercial applications. ...

Examples

Embodiment 1

[0047] The present embodiment provides a kind of airbag polishing method, comprises the following steps:

[0048] Drive the actuator to move toward the workpiece 5 to be polished according to the preset included angle and preset feed rate;

[0049] Obtain the pressure that the polishing head 4 acts on the workpiece 5 to be polished; the pressure is the force that the polishing head 4 acts on the workpiece 5 to be polished from multiple dimensions;

[0050] In any two-dimensional plane, calculate the actual pressure that the polishing head 4 acts vertically on the workpiece 5 to be polished in the current dimension according to the preset angle and pressure;

[0051] The present embodiment is illustrated with the situation in the X, Z two-dimensional plane, and the three-dimensional situation is deduced by analogy. Specifically, according to the obtained pressure and the angular relationship between the polishing head 4 and the workpiece 5 to be polished, the calculation of the...

Embodiment 2

[0082] This embodiment provides a kind of airbag polishing device, such as Figure 1-3 Shown, comprise polishing robot 1, also comprise the multi-dimensional force sensor 2 that is used to detect the pressure size that polishing head 4 acts on the workpiece 5 to be polished and the processor that is connected with multi-dimensional force sensor 2, one end of multi-dimensional force sensor 2 is connected with polishing The actuator of the robot 1 is connected, the other end of the multidimensional force sensor 2 is connected to the driving mechanism 3 for driving the polishing head 4 to rotate, and the polishing head 4 is arranged on the driving mechanism 3;

[0083] During polishing, the processor controls the airbag polishing device to perform polishing according to the airbag polishing method provided in Embodiment 1.

[0084] Limited by the rigidity and movement accuracy of the robot 1 itself, after the preset feed of the actuator is given, there is a deviation between the ...
