Blade surface grinding device

Abstract

The invention discloses a paddle surface grinding device, which comprises a base, a paddle chassis clamp, a paddle support rod, a gantry frame, a mechanical arm, an air-floating spindle, a conical grinding wheel, an inclination sensor, a curved surface detection component and a host computer. The mechanical arm is fixedly connected to the air-floating spindle; the air-floating spindle includes a mandrel and a pressure sensor; the conical grinding wheel is coaxially sleeved at the tail end of the mandrel, and the extension line of the conical generatrix of the conical grinding wheel is formed by the central axis of the conical grinding wheel. The included angle is 15°-75°; the inclination sensor is arranged on the non-grinding side of the conical grinding wheel; the curved surface detection component includes a horizontal horizontal plate and at least two laser sensors. The invention has a high degree of automation, can automatically plan the grinding path of the blade, can adapt to the complex blade curved surface, can automatically adjust the inclination angle of the conical grinding wheel, and makes the conical generatrix of the conical grinding wheel consistent with the blade curved surface, and at the same time, can The grinding force is controlled within a set range, so that the grinding precision is high.

Description

technical field [0001] The invention relates to the technical field of curved surface grinding, in particular to a paddle surface grinding device. Background technique [0002] At present, there are relatively few grinding machines for large propellers of large ships, and they mainly encounter the following problems: 1. The diameter of propeller blades is relatively large, and the grinding speed of general grinding machines cannot meet the requirements; 2. The grinding volume is large, requiring Constantly replace the grinding wheel, and the grinding of the propeller requires relatively high thickness and diameter of the grinding wheel, so as to ensure the grinding accuracy, so the general grinding machine cannot be completed; 3. The existing grinding wheel has poor stability, which is likely to cause safety hazards and property damage loss. The grinding machines currently used on large propellers generally have the disadvantages of poor pertinence, complicated and inconven...

[0002] At present, there are relatively few grinding machines for large propellers of large ships, and they mainly encounter the following problems: 1. The diameter of propeller blades is relatively large, and the grinding speed of general grinding machines cannot meet the requirements; 2. The grinding volume is large, requiring Constantly replace the grinding wheel, and the grinding of the propeller requires relatively high thickness and diameter of the grinding wheel, so as to ensure the grinding accuracy, so the general grinding machine cannot be completed; 3. The existing grinding wheel has poor stability, which is likely to cause safety hazards and property damage loss

[0007] 1. Non-automatic propeller grinding machine, each grinding action needs to be completed manually, the grinding efficiency is low, the precision is low and the labor cost is high

[0008] 2. Use mechanical equipment for grinding and polishing. The current equipment has a single function and can only polish part of the flat surface. It cannot adapt to complex curved surfaces and the accuracy is not high.
