Description
Technical field
The present invention relates to measurer, be specifically related to a kind of square thread gauge, be mainly used in the bigger product parts inspection and acceptance of diameter.
Background technology
By the general technical specifications requirement that national gauge is made, with the measurer that high-quality low carbon-structural steel (10,15, No. 20 steel) is made, its workplace is answered carburizing, or makes with high-carbon steel (CrWMn, CrMn, T10A, T12A steel etc.).Above-mentioned two kinds all to promptly quench through heat treatment step, temper, to reach the performance requirement of measurer, i.e. high rigidity, high-wearing feature, high dimensional stability.In addition, also the good grinding processability need be arranged, make measurer can reach very high smooth finish.All gauges through thermal treatment, welding or casting all should pass through Ageing Treatment., precision higher gauge big to size also must be through ice-cold processing.Existing standard gauge, processing technology complexity not only, manufacturing cost is higher, and restricted application, can not be used for making diameter greater than 200mm(form of thread triangle, trapezoidal, rectangle etc.) the part of threaded structure test.If make off-gauge external thread gauge by the general technical specifications requirement that national gauge is made, not only the difficulty of Sheng Chanzhizaoing is big, and the production cost height, so, there is not the special screw thread of this class (rectangle) gauge to sell on the market.Therefore, need break the normal procedure, looking for another way to manufacture is applicable to the external thread gauge that diameter is tested greater than the part of the threaded structure of 200mm.
Summary of the invention
The purpose of this invention is to provide a kind of square thread gauge, it can be applicable to tests greater than the part of the threaded structure of 200mm to diameter, guarantee product quality, and manufacturing procedure is few, the production efficiency height, and low cost of manufacture, usability is reliable.
A kind of square thread gauge of the present invention, comprise go side plug thread gauge and not-go-end plug thread gauge, it is characterized in that: the feeler gauge go side body of go side plug thread gauge is a spheroidal-graphite cast iron annulus, vertically is connected with the feeler gauge go side handle of two symmetries on an end face of feeler gauge go side body; The feeler gauge not-go-end body of not-go-end plug thread gauge also is a spheroidal-graphite cast iron annulus, vertically is connected with the feeler gauge not-go-end handle of two symmetries on an end face of feeler gauge not-go-end body.Circular go side plug thread gauge and circular not-go-end plug thread gauge can alleviate the weight of operator when using, and lower labour intensity.
Described a kind of square thread gauge is respectively equipped with four uniform lightening holes, with further weight reduction on feeler gauge go side body and feeler gauge not-go-end body.
A kind of square thread gauge of the present invention, comprise go side ring thread gage and not-go-end ring thread gage, it is characterized in that: the ring gauge go side body of go side ring thread gage is the annulus of a spheroidal-graphite cast iron, vertically is connected with the ring gauge go side handle of two symmetries on the outer circumference surface of ring gauge go side body; The ring gauge not-go-end body of not-go-end ring thread gage also is a spheroidal-graphite cast iron annulus, vertically is connected with the ring gauge not-go-end handle of two symmetries on the outer circumference surface of ring gauge not-go-end body.
The present invention select for use spheroidal-graphite cast iron (
QT20-40) replace measuring instrument steel to manufacture external thread gauge.According to the mechanical property of spheroidal-graphite cast iron as can be known, not only to cause stress to concentrate little for globular graphite.And under same graphite volume, the surface area minimum of globular graphite also drops to minimum to the effect of isolating of matrix, and therefore, the metallic matrix rate of utilization of strength of spheroidal-graphite cast iron can be up to 70-90%.The tensile strength of spheroidal-graphite cast iron, plasticity, toughness not only are higher than other cast irons, and can with graphite in the cast iron be the group cotton-shaped existence malleable cast iron compare favourably, its yield tensile ratio almost doubles than steel.Because spheroidal-graphite cast iron has globular graphite to exist, and makes it have some premium properties similar to grey cast iron, as casting character, antifriction quality, damping property, machinability etc.Adopt spheroidal-graphite cast iron to manufacture external thread gauge, can reduce the processing and manufacturing operation.Promptly only with one turning finishing, do not heat-treat and ageing treatment process, manufacturing cost is low, the production efficiency height, and usability is reliable, and particularly its advantage of the king-sized external thread gauge of double thread diameter is by for manifesting.
The present invention has following advantage compared to existing technology: reduced the processing and manufacturing operation, reduced manufacturing cost, guaranteed product quality, can raise labour productivity.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2, Fig. 3 and a kind of square thread gauge shown in Figure 4, comprise go side plug thread gauge and not-go-end plug thread gauge, the feeler gauge go side body 1 of go side plug thread gauge is a spheroidal-graphite cast iron annulus, on the body of feeler gauge go side, be provided with four lightening holes 9, on an end face of feeler gauge go side body, vertically be connected with the feeler gauge go side handle 2 of two symmetries; The feeler gauge not-go-end body 3 of not-go-end plug thread gauge also is a spheroidal-graphite cast iron annulus, is provided with four lightening holes 9 on feeler gauge not-go-end body 3, vertically is connected with the feeler gauge not-go-end handle 4 of two symmetries on an end face of feeler gauge not-go-end body.
Referring to Fig. 5, Fig. 6, Fig. 7 and of the present invention a kind of square thread gauge shown in Figure 8, comprise go side ring thread gage and not-go-end ring thread gage, the ring gauge go side body 5 of go side ring thread gage is the annulus of a spheroidal-graphite cast iron, vertically is connected with the ring gauge go side handle 6 of two symmetries on the outer circumference surface of ring gauge go side body; The ring gauge not-go-end body 7 of not-go-end ring thread gage also is a spheroidal-graphite cast iron annulus, vertically is connected with the ring gauge not-go-end handle 8 of two symmetries on the outer circumference surface of ring gauge not-go-end body.
When checking the external thread of product, use go side ring thread gage and not-go-end ring thread gage.If the go side ring thread gage passes through smoothly, and the not-go-end ring thread gage can not pass through, and then this product external thread of decidable is qualified.As the not-go-end ring thread gage can be defective by this product external thread of decidable then.
