Abstract
A kind of single screw rod groove depth survey tool uses following structure, including a kind of dial depth gauge and horizontal location device, wherein dial depth gauge includes gauge outfit and fixed length depth rod, horizontal location device is provided with U-shaped fluting, the lower surface of horizontal location device is provided with the cambered surface identical with outer screw diameter to be measured, and what fixed length depth rod was slided is fastened in fluting.Single screw rod groove depth survey tool is provided with the fastening bolt played the role of positioning；This is novel owing to taking above technical scheme; it has the advantage that the 1. little 0.01mm.3. of groove depth error that easily location 2. records do not deposit the single screw rod groove depths of the biggest 4. costs of the result error recorded after repeated use low 5 and can shut down on-line measurement .6. simple in construction, profile keeping little, easy and carry, easily safeguard.
Description
Technical field
Basis is the most novel relates to a kind of survey tool, particularly to one list screw rod groove depth survey tool.
Technical background
The instrument measuring now single screw rod groove depth uses common-depth slide calliper rule and micrometric depth gauge instrument to measure mostly, and the helicla flute of list screw rod is varying depth helicla flute, the measurement needs of this part maximum groove depth all can not be met owing to maximum groove depth only exists existing single formula survey tool on a specific cross section.
Utility model content
For the problems referred to above, this most novel purpose is through a set of easy device and is accurately positioned to find and only exists a specific cross section maximum groove depth on screw rod, and reaches measurement purpose by this particular cross section.
To achieve these goals, a kind of single screw rod groove depth survey tool uses following structure, including a kind of dial depth gauge and horizontal location device, wherein dial depth gauge includes gauge outfit and fixed length depth rod, horizontal location device is provided with U-shaped fluting, the lower surface of horizontal location device is provided with the cambered surface identical with outer screw diameter to be measured, and what fixed length depth rod was slided is fastened in fluting.
Single screw rod groove depth survey tool is provided with the fastening bolt played the role of positioning.
The opening end that the U-shaped of horizontal location device is slotted is provided with plug.
Use single screw rod that this kind of survey tool is measured; operation measurement can be carried out in screw rod processing is shut down; it is a kind of novel use technology shutting down on-line measurement instrument for single screw rod groove depth, uses horizontal location and comparative method for measuring mode to comprise all " instruments of horizontal centering, positioner and comparative method for measuring " etc..The comparative measurement method measuring bar with addition of fixed length with common-depth amesdial records the maximum helicla flute degree of depth.First on standard groove depth block, dial gauge zero-bit size is reserved with groove depth survey tool, slip gauge stand to pitch away from position (error ± 0.5mm, after calculating during centre-to-centre spacing error ± 0.5mm groove depth error is negligible for ± 0.001mm) fastened (adjusting amesdial head to make pointer position be 0), the measurement apparatus demarcated is put on screw rod to be checked be close to screw rod end face centre-to-centre spacing positioning datum the most slowly swing measurement apparatus observe pointer, stop when beat of pointer amplitude maximum position and write down total indicator reading (in gauge outfit, display is exactly workpiece groove depth and the deviation of target groove depth).
This is novel owing to taking above technical scheme; it has the advantage that the 1. little 0.01mm.3. of groove depth error that easily location 2. records do not deposit the single screw rod groove depths of the biggest 4. costs of the result error recorded after repeated use low 5 and can shut down on-line measurement .6. simple in construction, profile keeping little, easy and carry, easily safeguard.

Detailed description of the invention
A kind of single screw rod groove depth survey tool includes a kind of dial depth gauge and horizontal location device 1, wherein dial depth gauge includes gauge outfit 2 and fixed length depth rod 3, horizontal location device 1 is provided with U-shaped fluting 7, the lower surface of horizontal location device 1 is provided with the cambered surface 8 identical with outer screw diameter to be measured as shown in Figure 1A, and what fixed length depth rod 3 was slided is fastened in fluting 7.
Single screw rod groove depth survey tool is provided with the fastening bolt 6 played the role of positioning.
Being provided with plug 4 on the opening end of the U-shaped fluting 7 of horizontal location device, plug 4 is fixed by fluting flush end trip bolt 5.
Wherein, Fig. 3 and Fig. 3 A is measurement standard screw rod groove depth block figure, and Fig. 4 is single screw rod groove depth schematic diagram to be measured.
Gauge outfit 2 blocks slip by fixed length depth rod 3 in reference seat 1, and fastening bolt 6 plays the role of positioning, and plug 4 is prevented depth rod 3 from derailing by fluting flush end trip bolt 5 fastening.
Measure the step of groove depth N of single screw rod: on standard groove depth block, reserve size (adjusting amesdial head to make pointer position be 0) with groove depth survey tool the most as shown in Figure 3, the most slowly slip table to pitch away from position M(error ± 0.2mm, obtain groove depth N error after calculating during centre-to-centre spacing error ± 0.2mm to be negligible for ± 0.0001) fastened, it is put into centering position on screw rod to be checked the most as shown in Figure 4 to wait a moment to swing slowly and apparent examine pointer, stop when beat of pointer amplitude maximum position and write down total indicator reading (in gauge outfit, display is exactly workpiece groove depth and the deviation of target groove depth).
