Abstract
The utility model discloses an adjustable screw thread circular gauge, including a circular body and an internal screw thread with a standard specification dimension. The body is provided with a radial fracture; the body at two sides of the fracture is provided with a step through hole; the axis of the step through hole is vertical to the end surface of the fracture; a lining, an adjusting screw and a nut are provided in the step through hole; 1 to 4 same circular through holes are provided on the same circumference on the body and between the internal screw thread and the external circle; the axis of the through hole is parallel to the axis of the internal screw thread; a radial gap through groove is provided between each through hole and the internal screw thread; and distribution with equal intervals of the gap through holes and the fracture is formed on the same circumference. In the utility model, the width of the fracture is adjusted by adjusting the screw and the nut, the internal screw thread middle diameter dimension of the screw thread circular gauge can be adjusted finely, the qualified rate of the screw thread circular gauge is largely raised, the usage life of the screw thread circular gauge is prolonged, and wasted is minimized.
Description
Technical field
The utility model belongs to a kind of measurer, and what relate to is the special screw thread gauge of footpath size in a kind of comprehensive test external thread.
Background technology
The body of existing ring thread gage all is the rigid of a sealing, and after this ring thread gage shaped, the standard specification internal thread size on its ring gauge was determined value, can not adjust change, and qualification rate is lower; In the use, wearing and tearing can appear in the screw thread of ring gauge, when wearing and tearing cause when departing from standard specification and requiring, then can not continue to use, and can only scrap.Therefore, this ring thread gage life-span is shorter, wastes very big.
Summary of the invention
The purpose of the utility model is to overcome the defective that existing ring thread gage qualification rate is low, the life-span short, waste is big, and proposing a kind of pitch diameter of thread size can the micro-ring thread gage of adjusting.
The technical scheme that realizes above-mentioned purpose is: a kind of adjustable ring thread gage; The internal thread that comprises annular body and standard specification size; Radially fracture is arranged together on the said body; A step through-hole is arranged on the body on fracture both sides, and the axis normal of step through-hole is equipped with lining, adjustment screw and nut in the end face of fracture in the step through-hole; On the body; Internal thread is provided with 1-4 identical manhole with same circumference between the cylindrical; The parallel axes of through hole is in the internal thread axis; A gap groove is radially all arranged between each through hole and the internal thread, and these gap grooves and said fracture form on the same circumference of body equidistantly and distribute.
The width of said fracture is 1.5-2.5mm.
The utility model can be adjusted the width of fracture through adjustment screw and nut, can the internal thread of double thread ring gauge in the footpath size carry out trace adjustment.Therefore, can significantly improve the qualification rate of ring thread gage, the in a small amount ring thread gage of wearing and tearing arranged, only need do the trace adjustment and check and correction can continue to use, so just can prolong the serviceable life of ring thread gage, cut the waste the middle footpath size of its internal thread for internal thread.In addition, this adjustable ring thread gage only needs a check and correction feeler gauge to its adjustment check and correction, has reduced the quantity of supporting check and correction feeler gauge.

Fig. 2 is a unitary construction synoptic diagram embodiment illustrated in fig. 1.
Fig. 3 is the side view of Fig. 2.
The schematic perspective view of Fig. 4 present embodiment.
Among the figure: 1. body, 2. internal thread, 3. fracture, 4. step through-hole, 5. manhole, 6. gap groove, 7. lining, 8. adjustment screw, 9. nut.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in Fig. 1 to 4, the utility model adjustable ring thread gage comprises the annular body 1 of alloy steel material and the internal thread 2 of standard specification, and radially fracture 3 is arranged together on the body 1, and fracture 3 runs through the both ends of the surface of body 1, and its width is 1.5～2.5mm; A step through-hole 4 is arranged on the body 1 on fracture 3 both sides, and the axis normal of step through-hole 4 is equipped with lining 7 in the end face of fracture 3 in the step through-hole 4, and adjustment screw 8 passes lining 7 and cooperates with nut 9; On the body 1; Internal thread 2 is provided with two identical manholes 5 with same circumference between the body cylindrical; The parallel axes of manhole 5 is in the axis of internal thread 2; All having 6, two gap grooves of a gap groove radially 6 and fracture 3 on the same circumference of body 1, to form equidistantly between each manhole 5 and the internal thread 3 distributes.
What of manhole 5 on the body and gap groove 6 can confirm that screw thread nominal diameter size is less than be provided with 1 of 8mm according to the screw thread nominal diameter size of ring thread gage, and 8～200mm is provided with 3, greater than be provided with 4 of 200mm.
After ring thread gage body 1 is accomplished by Design and Machining, lining 7, adjustment screw 8 and nut 9 cooperations are installed in the step through-hole 4, with the check and correction feeler gauge that matches adjustable ring thread gage are carried out adjustment, adjustment can be used after reaching standard.When the internal thread of ring thread gage has wearing and tearing in a small amount and when departing from the standard specification size, can do the trace adjustment to the middle footpath size of internal thread 2 through screwing adjustment screw 8, again through the check and correction feeler gauge to its adjustment, adjustment can continue to use after reaching the standard specification size.
Claims (2)
1. adjustable ring thread gage; The internal thread that comprises annular body and standard specification size; It is characterized in that: radially fracture is arranged together on the said body; A step through-hole is arranged on the body on fracture both sides, and the axis normal of step through-hole is equipped with lining, adjustment screw and nut in the end face of fracture in the step through-hole; On the body; Internal thread is provided with 1-4 identical manhole with same circumference between the cylindrical; The parallel axes of through hole is in the internal thread axis; A gap groove is radially all arranged between each through hole and the internal thread, and these gap grooves and said fracture form on the same circumference of body equidistantly and distribute.
