Abstract

The invention discloses a laser ranging sensing based blank allowance automatic detection device and method and belongs to the technical field of automatic detection equipment. The method comprises the following steps of a workpiece blank is mounted in a clamp according to a designed positioning manner; a laser ranging sensor is carried by an industrial robot, the datum positions in an X direction, a Y direction and a Z direction in the clamp are measured, and blank sizes of the workpiece blank in the X direction, the Y direction and the Z direction relative to the datum positions are measured; and after measurement of all data is finished, a control system sends detection data to a host computer, and the host computer performs data processing and feeds a result back to a numerically-controlled machine tool. The laser ranging sensing based blank allowance automatic detection device and method have the beneficial effects that automatic feeding processing of the workpiece blanks is realized, manual marking and preprocessing rare replaced, the purposes of lowering the equipment cost and the labor cost are achieved, the processing qualified rate of the blanks is increased, and the automation level, the informatization level and the intelligence level of an automatic production line are promoted at the same time.

Description

technical field

[0001] The invention relates to a blank margin detection device, which belongs to the technical field of automatic detection equipment. Background technique

[0002] The traditional method of manual scribing to determine the machining allowance and processing benchmark of the blank can no longer meet the automation and high-efficiency operation requirements of the modern automated machining industry. Manual scribing has low efficiency, poor accuracy, and high technical requirements for workers. At the same time, a scribing platform is required Auxiliary equipment such as special equipment requires high labor costs.

[0003] At present, the domestic automatic machining production line must pretreat the blank before the parts go online. The rough reference or rough machining cannot be carried out in the automatic line. Other machining equipment must be used to complete the rough machining pretreatment of the workpiece, which reduces the production efficiency. ...
