Work piece flatness detection device based on die machining

Abstract

The invention relates to the technical field of work piece flatness detection, in particular to a work piece flatness detection device based on die machining. Four work piece auxiliary clamping partswhich are oppositely distributed in the front-back direction and the left-right direction are arranged on the upper surface of a horizontal table. Two horizontally-symmetrical guide rails are arrangedabove the horizontal table, the two ends of the two guide rails are fixed to the horizontal table through supporting columns, and the two guide rails are sleeved with sliding sleeves. The work pieceflatness detection device is novel in design and simple in structure. Flatness measurement can be carried out on a planar work piece and an arched-surface work piece. The measurement difficulty is reduced, and the precision of measurement data is improved. The problem that it is inconvenient to measure large-area and arched-surface work pieces through a leveling instrument traditionally is solved.A to-be-detected work piece is limited and fixed through the work piece auxiliary clamping parts, the problem that detection data is inaccurate due to movement of the work piece in the detection process is solved, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of workpiece flatness detection, in particular to a workpiece flatness detection device based on mold processing. Background technique [0002] Under the action of external force, the mold makes the blank into a tool with a specific shape and size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and engineering plastics, rubber, ceramics, etc. In the forming process of compression molding or injection molding of products, when the mold is ejected, it is easy to cause deformation of the workpiece. Therefore, the flatness of the workpiece needs to be tested after it is ejected to ensure the quality of the workpiece. [0003] Existing levelness detection of workpieces uses a spirit level as a measuring tool, but some workpieces have a large area, so it is inconvenient to use a level to measure, which increases the difficulty of measurement...

Problems solved by technology

[0003] Existing levelness detection of workpieces uses a spirit level as a measuring tool, but some workpieces have a large area, so it is inconvenient to use a level to measure, which increases the difficulty of measurement, and the measurement accuracy is not very high. There is no good way to measure the flatness of some arched surfaces, which can only be observed with the naked eye, which seriously affects the quality of the workpiece
