Problems solved by technology

[0009] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a contact scanning probe with constant and controllable measuring force, which further improves the measurement accuracy of the contact scanning and better avoids the failure caused by the measurement process. The surface contact of the measured object leads to problems such as surface damage of the measured object; in addition, it avoids the impact on the machining accuracy caused by the secondary clamping error of the workpiece, and improves the processing and measurement efficiency

Abstract

The invention discloses a controllable contact type scanning measurement head with constant measurement force, and relates to the field of precision measurement equipment. A clamping head shank (3) and a probe (1) are respectively arranged on the top and at the bottom of the measurement head (2); a data cable (4) and an air pipe joint (5) are arranged on the outer side of the measurement head (2); a base plate (17) is fixed at the bottom inside the measurement head (2) through a lower fixing plate (6); an air guide rail mounting plate (10) is arranged in the middle of the upper side of the base plate (17); two air guide rails (9) are fixed on the air guide rail mounting plate (10) and the base plate (17); hollow pipes (11) are inserted into the air guide rails (9); and a laser scale (14) and the probe (1) are respectively fixed at two ends of the hollow pipes (11) through an upper connection piece (81) and a lower connection piece (82). By the controllable contact type scanning measurement head, the contact type scanning measurement precision is improved, and the processing and measurement efficiency is improved.

Description

technical field [0001] The invention relates to the field of precision measuring equipment, and relates to a contact scanning measuring head with constant and controllable measuring force. Background technique [0002] Precision probes used in shape tolerance and surface roughness measurement equipment such as ultra-precision parts, precision molds, and optical mold cores generally fall into two categories: non-contact scanning probes and contact scanning probes. Non-contact scanning probes Due to the method of optical scanning to obtain the surface shape and position error of the measured workpiece, it is widely used, but because it must have an expensive optical system, its structure becomes complicated, and the current machine vision technology can identify The smallest size makes it difficult for this type of probe to have nanometer-level measurement accuracy, which cannot fully meet the application requirements. The contact scanning probe does not need to be equipped w...
