Embodiment
As Fig. 3-1 to shown in the 3-4, duplex measuring scale of internal ring groove, it has final drive shaft 31 as sounding rod and a pair of measuring head is housed in final drive shaft 31 ends is respectively front heads 36 and back measuring head 35, front heads 36 and back measuring head 35 constitute by two slides 41 that are shaped on the symmetry of tooth bar on it, the gearing mesh of two slides 41 and final drive shaft 31 ends; The pointer 3 that reads the inner groove diameter that is come by final drive shaft 31 rotation size conversion is housed at final drive shaft 31 middle parts; Be with outside final drive shaft 31 and read the main scale 2 that is moved axially the inner groove width that size conversion comes by final drive shaft, and main scale 2 and final drive shaft 31 relative positionings, main scale 2 is installed in the annular groove on the final drive shaft 31 and with final drive shaft 31 and moves axially.Slide 41 1 ends are shaped on tooth bar, and an other end and tooth bar end have a camber and camber end to make tapered point.The end end that slide 41 is shaped on tooth bar is fixed with end face retaining sheet 39 with screw 40.Back measuring head 35 is connected as one by rivet 38 and side plate 37, moves axially with final drive shaft 31 one side guarantee back measuring head 35 in the annular groove that snaps in final drive shaft 31 of side plate 37.Final drive shaft 31 other end fixed gears 26 also are in transmission connection by set of gears mechanism and the gear shaft 20 that is positioned at tooth rest 27, are set with handle 21 on the gear shaft 20, and index dial 16 is housed on the handle 21.Index dial 16 is installed on the handle 21 by stop reed 17, collar 19 and locating ring 23 usefulness screws 18.Main scale 2 one ends are connected with orienting sleeve 34 by fixed cover 32, on main scale 2 other ends rotating disk 5 and pointer 3 are housed, and the display window on the pointer 3 corresponding main scales 2 is being shaped on master calibration on the corresponding display window positions on the final drive shaft 31 simultaneously.Pointer 3 usefulness screws 4 are fixed on the rotating disk 5, and rotating disk 5 is installed in main scale 2 middle parts by axle sleeve 10, collar 9, stop reed 7, screw 8, arresting disc 6 usefulness screws 29.
Shown in accompanying drawing 1, the accompanying drawing 2, this duplex measuring scale adopts telescopic measuring head to realize the measurement of inner groove size.Adjust earlier measuring head to its radial dimension less than part diameter of bore D
0, measuring head is axially stretched into inner groove position in the hole, can be flexible so that measure the inner groove diameter dimension by measuring head.The pulling final drive shaft is that vernier (part 31) can be measured the inner groove width dimensions.
Here, the duplex measuring scale with gear ﹠ rack structure is that example is illustrated the present invention.Below " this dip stick " all refer to " duplex measuring scale of gear ﹠ rack structure ".
Shown in accompanying drawing 3-1-3-4, this dip stick is made up of 40 parts such as zero-bit pointer 3 and index dials 16 measuring head of two kinds of specifications (front heads 36, back measuring head 35), final drive shaft 31, the gear (14,25,26) of 3 kind of specification, the gear shaft (12,15,20) of 3 kinds of specifications, main scale.The ultimate principle of this dip stick is by said gear (gear shaft) transmission, make the final drive shaft 31 and the tooth bar of the measuring head other end mesh (accompanying drawing 4-1 and 4-2 are gear mechanism engagement sketch and rack-and-pinion engagement figure), the rotation of the circumferencial direction by handle 21 makes the measuring head radial expansion, scale by circumferencial direction, read the size behind the measuring head radial expansion, just can measure the diameter of inside groove.(be carved with vernier graduation on the final drive shaft 31 by spurring vernier scale during well width in measuring, again as vernier scale), back measuring head 35 moves with vernier (sees accompanying drawing 5, measuring head 35 and side plate 37 rivetings were together after rivet 38 was incited somebody to action, one side of side plate 37 snaps in the annular groove of final drive shaft 31, guarantee that back measuring head 35 moves axially with final drive shaft 31), the two sides of two groups of measuring heads contact with the inner groove two side respectively, reach the purpose of groove width in measuring.Be carved with master calibration on the main scale 2, read master calibration and vernier graduation, can read inside groove width dimensions value.
This dip stick can design the size of the gear ratio of dip stick and master calibration and vernier graduation as required and be made into the series of products of different size and precision.
All parts are machined part in the accompanying drawing.Can finish all part processing according to the Element Design drawing by the method for machining.Assemble according to wiring layout.As accompanying drawing 1-1,1-2, shown in Figure 5, the assembly method of measuring head is: measuring head spare 36 can be directly inserts with the gearing mesh of final drive shaft 31 and is adjusted to the measuring head end from the gathering sill of orienting sleeve 34 and is exposed at outside the orienting sleeve, and is with screw 40 that end face retaining sheet 39 is fixing again.Retaining sheet has guaranteed that measuring head does not withdraw from engagement in adjustment and the measuring process.With rivet 38 side plate 37 is riveted together with it earlier before measuring head spare 35 assembling, during assembling side plate is aimed at the positioning ring groove of final drive shaft 31, other step is with measuring head spare 36 installation step.
After finishing assembling, repair and grind the measuring head workplace, guarantee the due precision of workplace.Adjust main scale 2, main scale is aimed at vernier graduation 0 groove on the final drive shaft 31, tighten part 1 screw and get final product.
Before measuring the inside groove diameter, adopt milscale calibration measurement area of bed, rotate rotating disk 5 this moment, circumferencial direction 0 scale mark that pointer 3 is aimed on the final drive shaft.Rotary dial 16 makes the scale index line on its 0 scale mark aligning tooth rest 27.During measurement, turning handle 21 stretches in the groove gauge head, shown in accompanying drawing 1-1,1-2, until measuring head contact groove top, rocks gently and transfers to measuring head and stretch out the longest.Master calibration by pointer 3 indications is read integral part, reads tenths and percentile certificate by the scale of index dial 16 again, just can reach the purpose of measuring the inner groove diameter.
In measuring during well width, pulling tooth rest 27, and drive final drive shaft 31 and move with respect to orienting sleeve 34.Shown in accompanying drawing 5, accompanying drawing 2, one group of measuring head 36 is static with orienting sleeve 34 axial locations, and can endwisely slip on final drive shaft 31.Another group measuring head 35 can move axially with final drive shaft 31, measuring head 35 just can axially relatively move with measuring head 36 like this, two groups of measuring head both sides contact with the inner groove two sides, by reading the master calibration and the vernier graduation that reaches on the final drive shaft 31 on the main scale 2, can record inner groove width dimensions value.
