Abstract

The utility model provides a deep hole clearance groove measuring tool, including vernier depth gauge (1), depth gauge rule (1) includes blade (2), its characterized in that the end of blade (2) is opened there are rectangular channel (3), hook (4), the accurate measurement of being convenient for are measured to blade (2) terminal formation.

Description

A kind of deep hole undercut survey instrument
Technical field:
The invention belongs to special measurement instrument, relating to the instrument for measuring Fine and Deep Hole undercut width.
Background technology:
Man-hour is added at mechanical component, due to the singularity of design of part, need to increase a undercut at deep hole place, and the size of undercut has strict demand, when measuring the width 8.5mm of undercut, diameter due to measured place largest hole is 11mm, and limitations is large, uses vernier caliper and depth gage to carry out Measurement accuracy.And measuring head also cannot detect when using three coordinate measuring machine, cause workman to be difficult to when turning grasp the turning degree of depth, easily cause part overproof or scrap.
Technical scheme:
The utility model provides a kind of deep hole undercut survey instrument, and comprise pit gauge, described pit gauge comprises blade, it is characterized in that, has rectangular channel at the end of blade, and blade end is formed measures hook.
The width that a kind of embodiment of the present utility model measures hook adopts 2mm.Convenient operation during employing 2mm, and be not easy to produce vibration.
The utility model is converted by a common depth gage, leaves a measurement hook at the end face of repacking slide calliper rule.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model
Fig. 2 utilizes the utility model to carry out deep hole undercut outer face survey sheet
Fig. 3 utilizes the utility model to carry out deep hole undercut inner face survey sheet
Embodiment:
Composition graphs 1, the utility model comprises pit gauge 1, and pit gauge 1 comprises blade 2, it is characterized in that, has rectangular channel 3 at the end of blade 2, and blade 2 end is formed measures hook 4, and the width measuring hook adopts a.By the rectangular channel 3 of the end of blade 2, aperture can be entered comparatively measure in small deep hole by blade 2.The end face that measurement hook 4 can block undercut is measured.
Using method:
1: when measuring part undercut, repacking slide calliper rule being stretched in undercut, is stuck in an outer face of undercut with measurement hook, read the reading L on slide calliper rule 1, and make a record, as shown in Figure 2;
2: after reading reading, repacking slide calliper rule are extend into the inner face of undercut, read the reading L on slide calliper rule 2, and make a record, as shown in Figure 3;
3: by calculating the width of undercut, computing formula is: L=L 2-L 1+ a;
Wherein L 1be the slide calliper rule reading of first end face,
L 2for the slide calliper rule reading of another end face,
A is the width measuring hook.

Claims (2)

1. a deep hole undercut survey instrument, comprise vernier depth gauge (1), described pit gauge (1) comprises blade (2), it is characterized in that, have rectangular channel (3) at the end of described blade (2), described blade (2) end is formed measures hook (4).
2. deep hole undercut survey instrument according to claim 1, is characterized in that, the width of described measurement hook (4) adopts 2mm.
