Optical channel measuring machine

Abstract

The invention provides an optical channel measuring machine. The optical channel measuring machine comprises a measuring device, a feeding roller way, a qualified roller way, an unqualified roller way, a side pushing mechanism and a matched electric control device. The feeding roller way and the qualified roller way are assembled to be arranged in the linear direction. A measuring station is arranged at the joint of the feeding roller way and the qualified roller way, and the measuring device is installed at the measuring station; the unqualified roller way is arranged on one side of the downstream of the measuring station of the qualified roller way, and the side pushing mechanism is arranged on the other side of the downstream of the measuring station; and the measuring device is used for carrying out optical detection on the inner hole channel of a to-be-detected part. Specifically, the measuring device comprises a lifting frame, an upper lifting mechanism, a lower lifting mechanism, an upper measuring head group and a lower measuring head group, and the upper lifting mechanism and the lower lifting mechanism are respectively mounted on the lifting frame. The inner hole channelof the to-be-detected part can be detected, and damage to the inner wall is reduced.

Description

technical field [0001] The invention belongs to the field of automatic measurement, in particular to an optical channel measuring machine. Background technique [0002] During the casting process of engine components, various damages can occur on the sprue due to the complex process steps. The internal structure of the water channel and oil channel in the component is complex, which cannot be easily and reliably inspected by other technologies, and there may be various local casting defects, areas embedded with machined debris and sand core residues, etc., causing serious quality problems . [0003] Most of the existing measurement methods use pneumatic measurement, but the pneumatic measuring head and different parts of the same aperture of the workpiece to be measured have multiple relative movements, which will cause technical problems such as scratches on the hole wall. The patent [CN201721217829.2] proposes a pneumatic measuring instrument probe and a pneumatic measur...

Problems solved by technology

The internal structure of the water channel and oil channel in the component is complex, which cannot be easily and reliably inspected by other technologies, and there may be various local casting defects, areas embedded with machined debris and sand core residues, etc., causing serious quality problems

[0003] Most of the existing measurement methods use pneumatic measurement, but the pneumatic measuring head and different parts of the same aperture of the workpiece to be measured have multiple relative movements, which will cause technical problems such as hole wall scratches

The patent [CN201721217829.2] proposes a pneumatic measuring instrument probe and a pneumatic measuring instrument measuring device. By designing the probe structure of the pneumatic measuring instrument, the measurement of multiple measuring parts can be completed only by placing the part to be tested once. , to a certain extent, the problem of scratches on the inner wall is reduced, but the probe still needs to be closely connected with the inner wall of the aperture to be measured, resulting in certain scratch damage. The existing technology cannot solve this problem
