Abstract
The utility model discloses a ceramic plug gauge, including metal base, metal base's one end periphery nestification has the ceramic layer, is equipped with the adhesive linkage between metal base and the ceramic layer, and the adhesive linkage is established the ceramic layer adapter sleeve on metal base's outer anchor ring. The utility model increases the wear resistance of the measuring tool by embedding a ceramic layer on the periphery of the metal matrix, and the hardness of the ceramic can reach HRA92 degrees or more, so that the manufactured measuring tool has better wear resistance and the service life is more than 5 times that of a steel piece; meanwhile, the ceramic material has good thermal stability, and compared with a steel part, the deformation of the ceramic material is much smaller when the temperature is changed at the same level; due to the particularity of the ceramic material, the surface of the ceramic material can obtain a better surface roughness value after being processed, and the ceramic material is not easy to corrode and is more suitable for places with high precision requirements or severe environments.
Description
Technical Field
The utility model relates to a detect the spare part field, specifically be a pottery plug gauge.
Background
The plug gauge is a measuring tool, and is a commonly used plug gauge with a round hole and a thread plug gauge. The round hole plug gauge is made into a cylindrical shape, and the two ends of the round hole plug gauge are respectively a through end and a stop end and are used for checking the diameter of a hole. A thread plug gauge is a tool for measuring the correctness of the dimensions of an internal thread. The plug gauge can be divided into three types, namely common coarse threads, fine threads and pipe threads. Plug thread gauges with a pitch of 0.35 mm or less, a precision of class 2 and higher than class 2, and plug thread gauges with a pitch of 0.8 mm or less and a precision of class 3 have no end-stop gauge. The thread plug gauge below 100 mm is a taper shank thread plug gauge. More than 100 mm is a double-handle thread plug gauge.
The original round hole plug gauge is of an integral steel structure, and the highest hardness of alloy steel can only reach HRC62 degrees, so that when the round hole plug gauge is used for a measuring gauge with high frequency, the round hole plug gauge is easy to wear and short in service cycle; also, mass quality accidents may occur due to quality control failure caused by wear of the gauge.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a pottery plug gauge solves the above-mentioned problem of proposing.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the ceramic plug gauge comprises a metal base body, a ceramic layer is embedded at the periphery of one end of the metal base body, a bonding layer is arranged between the metal base body and the ceramic layer, and the ceramic layer is tightly sleeved on the outer annular surface of the metal base body through the bonding layer.
Preferably, the metal matrix is made of alloy steel, and the hardness is HRC62 degrees.
Preferably, the hardness of the ceramic layer is HRA92 degrees.
Compared with the prior art, the method has the following beneficial effects:
the utility model increases the wear resistance of the measuring tool by embedding a ceramic layer on the periphery of the metal matrix, and the hardness of the ceramic can reach HRA92 degrees, so that the manufactured measuring tool has better wear resistance and the service life is more than 5 times that of a steel piece; meanwhile, the ceramic material has good thermal stability, and compared with a steel part, the deformation of the ceramic material is much smaller when the temperature is changed at the same level; due to the particularity of the ceramic material, the surface of the ceramic material can obtain a better surface roughness value after being processed, and the ceramic material is not easy to corrode and is more suitable for places with high precision requirements or severe environments.
Drawings
FIG. 1 is a schematic structural view of a ceramic plug gauge;
in the figure: 1-metal matrix, 2-ceramic layer and 3-adhesive layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
