Automatic grinding and milling device and working method thereof

Abstract

The invention discloses an automatic grinding and milling device and working method thereof. The automatic grinding and milling device comprises a support for placing a workpieve, a workpiece positioning and clamping mechanism is arranged on the support, the workpiece positioning and clamping mechanism is used for fixing the workpiece to the support, a mechanical arm is arranged on one side of thesupport, an electric milling cutter device and a laser ranging device are arranged at the outer end of the mechanical arm, the laser ranging device is used for obtaining the actual thickness of eachdetection point position in a to-be-grinded area of the workpiece, and the mechanical arm drives the electric milling cutter device to grind and mill along the surface of the to-be-grinded area of theworkpiece according to the actual thickness of each detection point position. A robot is utilized to be matched with a milling cutter and high-precision laser to achieve full-automation operation, and the efficiency is high; the beat is fast, the efficiency is high, and the performance cost ratio is high; personnel is avoided in the whole process, and the risk of causing injury to the personnel is avoided; and the grinding height can be automatically adjusted in real time for products with inconsistent flatness, and the situation that milling is too deep or too shallow is avoided.

Description

technical field [0001] The invention relates to the field of battery tray manufacturing, in particular to an automatic grinding and milling device and a working method thereof. Background technique [0002] With the development of domestic new energy vehicles, the demand for aluminum alloy battery trays is also increasing. The technological process of the pallet mainly includes CNC machining, friction stir welding and arc welding. Among them, after the stirring welding is completed, due to the characteristics of the process itself, many burrs and flashes will be generated after the welding is completed, and because the welding deformation of the product cannot be avoided after stirring, the flatness of the product is generally poor. [0003] The main existing processing methods are manual use of angle grinders and machining by milling machines. Manual grinding mainly has the following problems: 1. The life of the grinding wheel blades is low, and frequent replacement is re...

AI Technical Summary

Problems solved by technology

Manual grinding mainly has the following problems: 1. The life of the grinding wheel blades is low, and frequent replacement is required to seriously affect the efficiency; 2. The labor cost is high; 3. The safety is poor, and the grinding wheel blades or the aluminum chips produced by grinding have the risk of causing injury to people.

[0004] Milling machine processing also has the following problems: 1. Manual real-time online operation is required, and the running speed is slow, high cost, and low efficiency; 2. The product has high requirements, requires good product flatness consistency, and poor product tolerance
