Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：
Fig. 1 is the utility model roller, the structural representation of the preferred embodiment of gauging instrument one of needle roller；
Fig. 2 is roller shown in Fig. 1, the side view of the gauging instrument of needle roller.
Embodiment
The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Fig. 1 and Fig. 2 are referred to, the utility model embodiment includes：
A kind of gauging instrument of roller, needle roller, including：Base, base is provided with dovetail mount 3.
Dovetail mount 3 drives it to move left and right by screw component, and screw component includes screw mandrel, regulation screw flange, dovetail mount
It is assemblied on screw mandrel, regulation screw flange driving dovetail mount is moved along screw mandrel.
After the height at workpiece rear benchmark 34, the lower benchmark 39 below workpiece are equipped with dovetail mount 3,
Benchmark 34 after height, including benchmark backer 36, benchmark backer 36 is in 120 ° of V forked types.
Lower benchmark 39 is benchmark under double knife edges, and the double knife edges are provided with dovetail configuration.
The top of workpiece 8 is provided with gauge head 38, gauge head and is connected with torsion spring table.
Gauge head is hard alloy single-edge gauge head, 0.2 μm of linearity ＜.
The gauge head is provided with depth of parallelism trimming piece 37, for adjusting the depth of parallelism between gauge head and lower benchmark.
Dovetail mount 2 is moved left and right with benchmark after dynamic height 34 and lower benchmark 39.
When measuring diameter of work size, workpiece 8 is disposed across on lower benchmark 39, side benchmark 34 rearward, when measurement workpiece is long
When spending size, workpiece is placed vertically on lower benchmark 39, side benchmark 34 rearward.
Shown in Fig. 1 and Fig. 2, when measuring 8 diameter dimension of workpiece, adjustment depth of parallelism micrometer adjusting screw 37 is to workpiece 8 in hilted broadsword
0.2 μm of error ＜ in mouth gauge head 38.Standard component traverse is pushed at benchmark backer 36, gauge outfit shows attached to standard component measured value
Closely, torsion spring table fine setting can make show value be accurate to position.Standard component promotes repeatedly, release repeatable accuracy less than 0.2 μm to be qualified,
Lock and micro change is had after all micrometer adjusting screws, bolt, when the fine setting that adjustable torsion spring gauge outfit is carried is consistent with standard component reading,
Now the direct measurement of measured workpiece 8 is the pin-point reading of its scale error value.
Designed using double knife edges benchmark, single-edge gauge head and there is micrometer adjusting screw to be adjusted in 0.2 μm, to improving accuracy test
It is beneficial, and can reduce influence of the rubbish to measurement, at the same ensure that the positioning stablity of workpiece 8, it is reliable.90 °, 180 ° of rotational workpieces
It is measurable to arrive oval numerical value.
Cylindrical benchmark is equipped with when measuring 8 length dimension of workpiece, the other end of lower benchmark 39, as long as so mobile double
Benchmark is to the lower section of gauge head 38 under the edge of a knife, puts measured workpiece 8 into vertically, adjustment micrometer adjusting screw 37 to the lower μ of benchmark parallel error ＜ 0.2
M is measurable length.Standard component length demarcation needle roller of redeeming oneself directly is pushed into after cylinder scaffold tower height on benchmark, mobile torsion spring table（1
μm precision）To standard component indicating value, lock after all trimming bolts, screw, fine setting torsion spring table itself is used instead to standard component exact value
Accurate reading can be accurately obtained during measured workpiece 8.
Height dimension measurement lower benchmark can respectively the needle roller such as φ 2mm, φ 4mm, the mm of φ 6 insertion be used as benchmark, so
It can provide convenient to φ 2mm~φ 6mm needle roller measurement.As φ 2mm × 3mm needle roller finger is all pinched incessantly, in the instrument
On can be convenient for measuring.And the rear benchmark of height dimension measurement use 120 ° of V forks to be designed for the positioning of small needle roller.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
