Abstract
The invention discloses a kind of ball-and-socket depth check tools, it is characterised in that: including dial gauge, resilient sleeve, table folder, main body, measuring staff, steel ball and pin；Table folder covers on the handle of dial gauge, flexible set between table folder and handle, table folder injects in main body again, the measuring head of dial gauge is contacted with the measuring staff in main body, the other end of measuring staff is contacted with steel ball, steel ball and measuring staff pass through pin a respectively and pin b interference is positioned in main body, and table folder is positioned in main body by pin c, also fill reset spring at measuring head and measuring staff.The steel ball radius is less than ball-and-socket radius.Fit clearance between the measuring staff and main body is 0.005~0.008mm.It is the interference fit of H7/N6 between the pin a and main body.There is the gap 0.5~1mm between the steel ball and pin a.The configuration of the present invention is simple is reasonable, easy to use, measurement is accurate, and low in cost, cubing body is unlikely to deform, and greatly improves detection efficiency.
Description
[technical field]
The present invention relates to fields of measurement more particularly to a kind of ball-and-socket depth check tools.
[background technique]
In gage measuring, need to measure the depth dimensions of a ball-and-socket slot on some part, as shown in Figure 1, depth dimensions
For 3.03 ± 0.05mm, radius R11.4 ± 0.02mm.
[summary of the invention]
In view of the problems of the existing technology, the purpose of the present invention is to provide a kind of simple and reasonable, balls easy to use
Nest depth check tool.
The technical solution adopted by the present invention is that: a kind of ball-and-socket depth check tool, it is characterised in that: including dial gauge, resilient sleeve,
Table folder, main body, measuring staff, steel ball and pin；Table folder covers on the handle of dial gauge, and flexible set, table folder inject again between table folder and handle
In main body, the measuring head of dial gauge is contacted with the measuring staff in main body, and the other end of measuring staff is contacted with steel ball, steel ball and measuring staff difference
It is positioned in main body by pin a and pin b interference, table folder is positioned in main body by pin c, and also dress resets bullet at measuring head and measuring staff
Spring.
The steel ball radius is less than ball-and-socket radius.
Fit clearance between the measuring staff and main body is 0.005~0.008mm.
It is the interference fit of H7/N6 between the pin a and main body.
There is the gap 0.5~1mm between the steel ball and pin a.
The beneficial effects of the present invention are: accurately, low in cost, cubing body is or not simple and reasonable, easy to use, measurement
It is easily-deformable, and greatly improve detection efficiency.

[specific embodiment]
Referring to attached drawing, present invention employs a kind of ball-and-socket depth check tools, it is characterised in that: including dial gauge, resilient sleeve, table folder,
Main body, measuring staff, steel ball and pin；Table folder covers on the handle of dial gauge, and flexible set, table folder inject main body again between table folder and handle
In, the measuring head of dial gauge is contacted with the measuring staff in main body, and the other end of measuring staff is contacted with steel ball, and steel ball and measuring staff pass through respectively
Pin a and pin b interference are positioned in main body, and table folder is positioned in main body by pin c, also fill reset spring at measuring head and measuring staff.
The steel ball radius is less than ball-and-socket radius.
Fit clearance between the measuring staff and main body is 0.005~0.008mm.
It is the interference fit of H7/N6 between the pin a and main body.
There is the gap 0.5~1mm between the steel ball and pin a.
When measurement, measuring tool is put on workpiece, the face cubing M is made to be close to the face workpiece P, slightly all around movement is once examined
Tool allows the specific steel ball contact ball-and-socket of inspection to meet low spot, measures.
The preferred embodiment of the invention, including inventor's best modes known for carrying out the present invention are illustrated herein.
The change of preferred embodiment is obvious after reading the above description for those of ordinary skill in the art.Inventor is uncommon
Those of ordinary skill is hoped rationally to apply such change, and inventor thinks different from clearly stating herein using can also be with
Realize the present invention.Therefore, the present invention includes all modifications and equivalents of purport cited in appended claims, this
It is allowed in applicable law.In addition, any combination of all possible change of above-mentioned element is also encompassed by the present invention,
It is unless otherwise indicated herein or clearly contradicted within a context.
