Abstract
The utility model discloses a thread gauge, which comprises a rod, a go and a not-go. The go holds a body. One end of go is fixed at one side of the rod and the other end of body is provided with a plurality of through external threads with valid size on basis of national standard. The not-go includes a body. One end of go is fixed at one side of the rod and the other end of body is provided with a plurality of go-through external threads. The valid size of the not-go external thread is larger than that of go external thread . The not-go external thread is same leveled specification with the go external thread. The front end thread diameter is thin while the rear end thread diameter is thick for go external thread and not-go external thread of this thread gauge.
Description
Technical field
The utility model relates to a kind of ridge rule, relates in particular to a kind of ridge rule of accurate and accurate detection internal thread.
Background technology
In the hardware products, it is by being connected of internal and external threads that much more very products are arranged, for example in the nuts and bolt, and two oil pipes or water pipe or the like, the precision of screw thread manufacturing just is directly connected to the quality quality of entire product.
Ridge rule are that all five metals production industry screw threads detect necessary instruments, and ridge rule are used for detecting the precision of internal thread, and it can carry out the testing of screw thread at short notice, its double thread detect guaranteed mass-producted high-quality.
Summary of the invention
The purpose of this utility model is to provide a kind of ridge rule, the detection internal thread that it can be accurate and accurate.
For achieving the above object, the utility model provides a kind of ridge rule, it comprises a body of rod, one logical side, one not-go, should logical side comprise a body, this body one end is fixed on an end of this body of rod, the other end of this body is provided with some external threads that lead to, this can lead to the effective diameter size that external thread has national Specification, this not-go comprises a body, one end of this not-go body is fixed on the other end of this body of rod, the other end of this not-go body is provided with some logical external threads that end, and should end logical externally threaded effective diameter size and can lead to externally threaded effective diameter size greater than this.
Logical external thread should be ended and external thread specification at the same level can be led to this.
The led to external thread of these ridge rule and only logical externally threaded front end diameter of screw are thin, and the rear end diameter of screw is thick.
The utlity model has following beneficial effect: this ridge rule are provided with can lead to external thread and effective diameter size and be slightly larger than this and can lead to the externally threaded logical external thread that ends, therefore use the manufacturing accuracy of the accurate and accurate detection internal thread of this ridge rule energy, improve the yield of product.
Description of drawings
Fig. 1 is the front view of the utility model ridge rule.
Fig. 2 is the left view of the utility model ridge rule.
Embodiment
See also Fig. 1 to Fig. 2, a kind of ridge rule, it is one shaft-like that integral body is, and it comprises a body of rod 1, one logical side 2, a not-go 3.
This body of rod 1 usefulness plastic material is made a hexagon prism shape, and the tester clamps this body 1 this ridge rule of can conveniently holding steadily with finger, and can be easy to rotate this ridge rule.
The body 22 that should logical side 2 comprises a metal circular tube shape, an end of this body 22 is fixed on an end of this body of rod 1 through injection moulding, and the other end of this body 22 is provided with some external threads 24 that lead to, and this can lead to the effective diameter size that external thread 24 has national Specification.
This not-go 3 comprises the body 32 of a metal circular tube shape, one end of this body 32 is fixed on the other end of this body of rod 1 through injection moulding, the other end of this body 32 is provided with some logical external threads 34 that end, and the effective diameter size that should end logical external thread 34 is slightly larger than the effective diameter size that this can lead to external thread 24.
It is specifications at the same level that only logical external thread 34 of the present utility model can lead to external thread 24 with this.
When detecting, find ridge rule earlier with internal thread to be measured (figure does not show) specification at the same level; Then the logical side 2 of these ridge rule is inserted in this internal thread, rotation ridge rule, if can leading to external thread 24, this can pass through this internal thread, the logical external thread 34 of ending of this not-go 3 is inserted in this internal thread, rotation ridge rule, can not continue to screw in if be blocked in the time of should ending in logical two revolutions of this internal thread of external thread 34 precessions, the error of then representing this internal thread is within national standard, and this internal thread is qualified.
According to the occasion difference of using, also different for the requirement of internal thread precision, roughly can be divided into three kinds: screw thread is used gauge ridge rule, standard tooth rule, effective tooth rule.
Screw thread with gauge ridge rule be divided into screw thread that work uses with gauge ridge rule and the screw thread of checking usefulness with gauge ridge rule.
Effective tooth rule are divided into effective parallel thread tooth rule and effective oblique ridge is advised two kinds, and effective parallel thread tooth rule using method is identical with gauge ridge rule with screw thread.The diameter of screw that the led to external thread of effective oblique ridge rule and only logical externally threaded screw thread all are front ends is thinner, and the diameter of screw of rear end is thicker, and effective oblique ridge rule are that end face otch to the terminal otch of goods is an acceptability limit.
In the utility model, the body 22 and the body 32 of this logical side 2 and not-go 3 can cylindrical shapes.
This ridge rule are provided with can lead to external thread 24 and effective diameter size and be slightly larger than this and can lead to the logical external thread 34 of ending of external thread 24, therefore uses the manufacturing accuracy of the detection internal thread that these ridge rule can be accurate and accurate, improves the yield of product.
