Abstract
The invention relates to a device for measuring pitch diameter. The device comprises a three-needle hanging rod, a fixture body, a pressing plate, a fixing screw and a nut, wherein the three-needle hanging rod is fixed on the fixture body through the nut; the fixing screw passes through a threaded hole; and the pressing plate tightly presses a micrometer and is vertically arranged on the fixture body. By the device, the pitch diameter is simply measured, work efficiency is improved, and the measured pitch diameter value is accurate and reliable.
Description
Technical field
The present invention relates to a kind of screw measurement device, particularly a kind of device of measuring the pitch diameter of thread.
Background technology
The staff is when measuring the pitch diameter of thread, when particularly measuring the pitch diameter of thread of interference thread part, should hold tested part, also will hold steadily three pins and milscale, make part and three pins be in detected state, also will regulate the measurement mechanism of milscale, use quite difficulty, efficient is very low, but also may cause that measuring inaccurate phenomenon takes place.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of easy to operate and measure the device measure the pitch diameter of thread accurately.
This measurement mechanism comprises: three pin pegs, clamp body, pressing plate, gib screw, nut; Three pin pegs are fixed on the clamp body by nut, and gib screw passes threaded hole, by pressing plate milscale is compressed, and pressing plate vertically is placed on the clamp body.
The α value of clamp body is 35～50 degree.
Use this device, make the measurement pitch diameter of thread become very simple, improved work efficiency, the pitch diameter of thread value of measurement accurately and reliably.
Description of drawings
Fig. 1 is the front view of the structural representation of the present invention's device of measuring the pitch diameter of thread;
Fig. 2 is the left view of the structural representation of the present invention's device of measuring the pitch diameter of thread;
Embodiment
As shown in Figure 1, the device of the measurement pitch diameter of thread of the present invention comprises: three pin pegs 1, clamp body 2, pressing plate 3, gib screw 4, nut 5.
Can find out that from Fig. 1 and Fig. 2 in this device, milscale 7 is placed on the clamp body 2, gib screw 4 passes threaded hole 9, by pressing plate 3 milscale 7 is pressed on the clamp body 2, and pressing plate 3 can protect milscale 7 not to be damaged.Pressing plate 3 is portable plates, vertically is placed on the clamp body 2.Three pins 6 are hung on the three pin pegs 1 of device, take detected part 8 during measurement on the other hand, the another hand is then regulated the measurement mechanism of milscale 7, very easy to use, improved efficient, the pitch diameter of thread value of measurement has solved the difficulty when in the past measuring the pitch diameter of thread accurately and reliably.Survey numerical value for the ease of observation post, clamp body 2 is designed to certain tilt angle alpha, when handle assembly was placed on the work top, device just formed an angle with worktable, and the staff just can observe the reading of milscale 7 accurately and easily.Be in good detection position for ease of three pins 6, three pin pegs 1 can be adjusted according to measuring needs, adjust the back and tighten by nut 5.Screw 4 twisting Position Design are become four circular arcs, be convenient to gib screw 4 and tighten smoothly.
The present invention takes cheaply that machining process carries out the processing of clamp body 2, gib screw 4, pressing plate 3 and three pin pegs 1, with nut 5 three pin pegs 1 is fixed on the clamp body 2, has reduced difficulty of processing, installs milscale 7 during use and three pins 6 get final product.
The present invention is simple in structure, and is with low cost, easy to operate, safe and reliable, easy to implement, and effect is obvious, can promote the use to machine industry.
