Abstract

The utility model relates to a device for measuring the pitch diameter of an external thread, which comprises a measuring table base, a fixed measuring bar, measuring bar fixing screws, a three-pin left clamping plate, three pins, a three-pin right clamping plate, a movable measuring bar and a measuring instrument, wherein the three-pin left clamping plate is fixed at one end of the fixed measuring bar, and the fixed measuring bar is positioned and fastened by the measuring bar fixing screws through a corresponding hole on the measuring table base; the three-pin right clamping plate is fixed at one end of the movable measuring bar, the measuring instrument is fixed at the other end of the movable measuring bar, and the movable measuring bar is positioned and fastened by the measuring bar fixing screws through a corresponding hole on the measuring table base; and the three pins are respectively inserted and fixed in corresponding holes of the three-pin left clamping plate and the three-pin right clamping plate. By using the measuring device, the dimension of the pitch diameter of a thread can be conveniently measured; and the measuring device has the advantages of simple structure, low cost and no requirements for precise measuring instrument and special environment.

Description

The measurement mechanism in footpath in a kind of external thread
Technical field
The utility model belongs to mechanical manufacturing field, the measurement mechanism in footpath in particularly a kind of external thread.
Background technology
Threaded male fastener relates generally to fields such as industry, agricultural, science and technology, Aero-Space, and is almost ubiquitous with our life.The quality of threaded male fastener is fine or not, directly have influence on structure, performance and the life-span of product that we use, and the size of the threaded male fastener pitch diameter of thread is one of key factor that directly influences its usability.Therefore, in manufacture process, the measuring method of the threaded male fastener pitch diameter of thread also has a variety of according to its request for utilization and process scale different, and like screw measurement machine, horizontal metroscope etc., its price, environmental requirement etc. are also different.Generally the general measurement means of processing enterprise the footpath, adopts the method in the single middle footpath of three pins measurement comparatively general in using special-purpose ring thread gage measurement threaded function, especially directly has when requiring specially in the double thread.
The utility model content
The technical matters that the utility model will solve provides a kind of device of making footpath in the simple and easy to operate measurement external thread.
The measurement mechanism in footpath in a kind of external thread, this device comprises: test desk base, fixedly measuring staff, measuring staff gib screw, three pins left side clamp, three pins, three pins right side clamp, movable measuring staff, measurement instrument.Three pins left sides clamp is fixed on a fixedly end of measuring staff, and fixedly measuring staff passes on the test desk base corresponding hole and locatees fastening by the measuring staff gib screw; The right clamp of three pins is fixed on an end of movable measuring staff, and measurement instrument is fixed on the other end of movable measuring staff, and it is fastening by measuring staff gib screw location that movable measuring staff passes on the test desk base corresponding hole; Three pins insert respectively in fixing left clamp of three pins and the corresponding hole of the right clamp of three pins.
Adopt this measurement mechanism can measure the size of the pitch diameter of thread easily, and this measurement mechanism is simple in structure, with low cost, need not accurate measurement instrument and special environment.
Description of drawings
Fig. 1 is the structural representation of the measurement mechanism in footpath in the utility model external thread;
Embodiment
The utility model provides a kind of measurement mechanism that three skill of handling needles are measured footpath in the external thread fast that passes through.As shown in Figure 1, this measurement mechanism mainly comprises: test desk base 1, fixedly measuring staff 2, measuring staff gib screw 3, three pins left side clamp 4, three pins 5, the right clamp 7 of three pins, movable measuring staff 8, measuring staff gib screw 9, measurement instrument 10.Three pins left sides clamp 4 is fixed on a fixedly end of measuring staff 2, and fixedly measuring staff 2 passes on the test desk base 1 accordingly the hole and locatees fastening by measuring staff gib screw 3; The right clamp 7 of three pins is fixed on an end of movable measuring staff 8, and measurement instrument 10 is fixed on the other end of movable measuring staff 8, and it is fastening by measuring staff gib screw 9 location that movable measuring staff 8 passes on the test desk base 1 corresponding hole; Three pins 5 insert respectively in three pin fixing chuck plates, 4, the 7 corresponding holes.
This measurement mechanism is taked general measuring method, and measurement mechanism is improved, and moves measuring staff to rotation and uses the mode that straight line moves instead, changes manual placement three pins 5 into fixing chuck plate and lays three pins 5.During measurement, three pins left sides clamp 4 and right clamp 7 are installed in fixedly on the measuring staff 2 and movable measuring staff 8, adjust behind three pin fixing chuck plates, 4,7 positions fixing; According to the size of measured piece 6 sizes, move movable fixed measuring staff 2, produce certain decrement; To zero-bit, tighten fixedly measuring staff 2 of measuring staff gib screw 3 with gauge block, take off gauge block; Insert three pins 5 respectively in the hole of three pin fixing chuck plates 4,7, activity compression measuring staff 8 places measured piece 6 between two measurement faces; Unclamp movable measuring staff 8, can measured piece 6 flank of thread be contacted with three pins and measure, draw measurement result through measurement instrument 10.The sounding rod of the utility model device through horizontal fast moving measurement instrument 10 contacts with three pins 5, measured piece 6 screw threads, and the displayed value through measurement instrument 10 draws measurement result.
Adopt the utility model measurement mechanism to have the following advantages:
1, this device changes the measuring staff of original metering system rotation move mode into the straight line move mode, has effectively practiced thrift the traveling time of measuring staff, has improved efficient.
2, adopt fixation measuring force measurement instrument, reduced the measuring error difference that the ergometry that causes because of human factor differs and produces, increased the stability of measurement result.
3, this device adopts three pin fixed mechanisms, has reduced the time of artificial plug three pins and the wearing and tearing of three pins, thus the serviceable life of having improved efficient and three pins.
4, this installation cost is cheap, and is simple in structure, light, need not accurate measuring mechanism and special environment, auxiliary equipment.
The present invention is economical and practical, is easy to realize that effect is obvious, can be popularized and applied to various threaded male fastener processing industries.
