Problems solved by technology

[0003] However, due to different human experience, the height difference data inspected by vernier calipers or micrometers often has large errors, and in the case of unknown whether the reference plane of the workpiece is a standard plane, the data reliability of vernier calipers or micrometer inspections often cannot reach the accuracy of the workpiece. Accuracy requirements, and vernier caliper or micrometer inspection efficiency is low, not suitable for high-volume workpiece height difference inspection

Abstract

The invention relates to an inspection device for inspecting the height difference of the bottom surface of a workpiece. The device comprises a bottom plate, the middle part of the bottom plate is vertically and fixedly provided with a fixed block, and the two sides of the bottom plate are movably provided with dial indicators. An inspection bench extends out of one side of the fixing block, a plurality of limiting cavities which are symmetrical in a midspan mode are formed in the inspection bench, and inspection units are axially and slidably connected into the limiting cavities; the two ends of each inspection unit axially penetrate through the inspection bench, the bottom of each inspection unit abuts against the detection end of the dial indicator, and the tops of the multiple inspection units elastically support a workpiece to be inspected. The inspection device can conveniently and quickly inspect the height difference between the reference plane of the workpiece and the protruding part of the workpiece, the inspection precision is high, and the inspection efficiency is obviously improved compared with manual inspection by adopting a vernier caliper or a micrometer.

Description

technical field [0001] The invention relates to the technical field of mechanical tooling, in particular to an inspection device for inspecting the height difference of the bottom surface of a workpiece. Background technique [0002] In the field of workpiece machining with high precision requirements, the dimensional accuracy of each part of the workpiece needs to be inspected after the machining is completed, especially the inspection of the relative height difference between a certain plane of the workpiece and a certain protrusion of the workpiece is more common. The reference plane of the workpiece or the highest point of the protrusion of the workpiece is fixed, and the height difference between the two is measured by a vernier caliper or a micrometer after the two are fixed. [0003] However, due to different human experience, the height difference data inspected by vernier calipers or micrometers often has large errors, and in the case of unknown whether the referenc...
