Embodiment Construction

[0020] Such as Figure 1-2 As can be seen, the present invention includes: a measuring head 1, a holding ring 2, an air mandrel 3, a handle 4 and a trachea connector 5, the measuring head 1 is provided with an air mandrel 3, and the air mandrel 3 There are multiple gas path grooves which do not intersect with each other. The end of each gas mandrel 3 away from the guiding side of the measuring head 1 is provided with a gas pipe joint 5, and the outer sleeve is provided with a holding ring 2. The holding ring 2 The end away from the guiding side of the measuring head 1 is sleeved with a handle 4 .

[0021] In this implementation, preferably, the air outlet hole of the air mandrel 3 corresponds to the air outlet hole of the measuring head 1 .

[0022] With the above-mentioned structure, the positions of the air mandrel 3 and the air hole of the measuring head 1 are corresponding, which ensures the unobstructed air path.

[0023] In this implementation, it is preferable that th...

Abstract

The invention provides a pneumatic measuring head structure for multi-section aperture detection. The structure comprises a measuring head, a clasping ring, a gas core shaft, a handle and a gas pipe joint, the gas core shaft is arranged in the measuring head, a plurality of gas path grooves of the gas core shaft are not intersected, one end of each gas core shaft far away from the guide side of the measuring head is provided with the gas pipe joint, the clasping ring is sleeved outside, and one end of the clasping ring far away from the guide side is sleeved with the handle. The air core is convenient to process, and an air circuit loop is simple and easy to realize; pneumatic measurement of diameters of multiple positions is achieved, and the cost is low compared with electronic measurement; pneumatic measurement and non-contact measurement of diameters of multiple positions are realized, and the probability of scratching a workpiece is greatly reduced.

Description

technical field [0001] The invention mainly relates to the field of pneumatic measurement, in particular to a structure of a pneumatic measuring head for multi-section aperture detection. Background technique [0002] Pneumatic measurement is a very advantageous measurement method with simple structure and low cost. It only needs a stable clean air source, and the air pressure signal can be converted into a voltage signal through the gas-electric conversion module to achieve the purpose of measurement. [0003] Ordinary pneumatic probes mostly measure a single diameter. For some special measurement occasions, it is necessary to measure the diameter of multiple positions. For example, the cylinder head camshaft hole, the cylinder head of a four-cylinder engine has a fifth-speed camshaft hole, and five diameters must be measured at the same time. The traditional method is to set up one gas path for each measurement position, and set up five gas paths for five diameters. Due...
