Footpath and groove.At present, existing inside plain calipers is the mechanical inside plain calipers of two-legged type mostly, and this two-legged type inside plain calipers is for aperture relatively
Greatly, the deeper part of endoporus is difficult to measure, always the difficult problem in workman's processing and detection.For this reason, applicant is in prior art
On the basis of improve a kind of mechanical inside plain calipers, it utilizes the equal principle in each side of two congruent triangles and angle in error
Can effectively solve the above problems in the range of permission.
Content of the invention：
For the problem overcoming prior art to exist, this utility model provides a kind of mechanical type inside plain calipers, makes up two-legged type
Deficiency in terms of inside diameter measurement for the mechanical inside plain calipers, facilitates the big part in hole depth, aperture in workman's measurement.
For solving above-mentioned technical problem, this utility model takes technical scheme below：
A kind of mechanical type inside plain calipers, including measurement pincers foot, its feature is：Described measurement pincers foot passes through block fixed-link
In clamp block, clamp block is provided with tabletting, and tabletting is fixed together by slotted countersunk flat head screw with measurement pincers foot and block；Institute
The one end stating clamp block is provided with bearing gland, and the other end is provided with bearing, and its bearing gland is bolted with clamp block and links, bolt
It is provided with a spring washer and bearing gland between；Inner ring one end of described bearing is fitted with rotating shaft, and the other end is provided with axle elasticity
Back-up ring, realizes the positioning of bearing and rotating shaft by circlip for shaft；Described clamp block is provided with felt collar, the internal diameter of felt collar with turn
Axle connects, and external diameter is connected with clamp block.
Above-mentioned measurement pincers foot is made up of two groups of measurement pincers feet, that is, include measurement pincers foot and lower measurement pincers foot.
Above-mentioned bearing is deep groove ball bearing, and its outer ring one end fits in the inner hole surface of clamp block；
Above-mentioned upper measurement pincers foot is identical with the length of lower measurement pincers foot, and the angle between upper measurement pincers foot and lower measurement
Angle between pincers foot is identical, realizes measurement of equal value with this.
This utility model mechanical type inside plain calipers utilizes the equal principle in each side of two congruent triangles and angle it is desirable to mechanical type
Four measurement pincers foot sizes of inside plain calipers are essentially equal, to ensure certainty of measurement.Wherein, lower measurement pincers foot is connect with workpiece hole inwall
Touch, upper measurement pincers foot, as the pincers foot of gage measuring data, thus realizing translating up of deep hole internal diameter size, is easy to measurement
Instrument direct measurement.
The beneficial effects of the utility model are：This mechanical type inside plain calipers is easy to use, simple to operate, and certainty of measurement is high,
Compensate for deficiency in terms of inside diameter measurement for the prior art, facilitate the big part in hole depth, aperture in workman's measurement.
Brief description：

Back-up ring, 8- rotating shaft, 9- bearing, 10- felt collar, 11- tabletting, 12- slotted countersunk flat head screw, measurement pincers foot on 13-, measurement pincers under 14-
Foot, 15- measured workpiece.
Specific embodiment：
Below in conjunction with the accompanying drawings the technical solution of the utility model is described in detail.
As shown in Figure 1 and Figure 2, a kind of mechanical type inside plain calipers, including measurement pincers foot 1, it is solid that described measurement pincers foot 1 passes through block 2
Surely it is linked in clamp block 3, clamp block 3 is provided with tabletting 11, tabletting 11 passes through slotted countersunk flat head screw 12 with measurement pincers foot 1 and block 2
It is fixed together；One end of described clamp block 3 is provided with bearing gland 4, and the other end is provided with bearing 9, its bearing gland 4 and clamp block
3 pass through bolt 6 fixed-link, are provided with a spring washer 5 between bolt 6 and bearing gland 4；Inner ring one end patch of described bearing 9
Conjunction has rotating shaft 8, and the other end is provided with circlip for shaft 7, realizes the positioning of bearing 9 and rotating shaft 8 by circlip for shaft 7；
Described clamp block 3 is provided with felt collar 10, and the internal diameter of felt collar 10 is connected with rotating shaft 8, and external diameter is connected with clamp block 3；Described bearing 9 is deep
Ditch ball bearing, its outer ring one end fits in the inner hole surface of clamp block 3；
Described measurement pincers foot 1 is made up of two groups of measurement pincers feet, that is, include measurement pincers foot 13 and lower measurement pincers foot 14；Described
