Abstract
The utility model relates to measuring instruments, and particularly relates to a digital display vernier scale for an oil cylinder trench inner diameter, comprising a digital display depth gauge, the display vernier scale is especially characterized in that: a supporting base is designed, the ruler frame of the digital display depth gauge is fixed on the supporting gbase via left and right pressed block screws, the tail end of the supporting base is provided with a boss, the boss is provided with an adjustable measuring rod extending backward, the central line of the adjustable measuring rod and the long-direction center line of the digital display depth gauge body are coaxially arranged; the digital display vernier scale in the utility model solves the problem of difficult measurement of oil cylinder trench inner diameter and can be widely used for trench inner diameter measurement of various cylindrical workpieces with deep and shallow trenches.
Description
(1) technical field: the utility model relates to survey instrument, especially a kind of oil cylinder groove internal diameter digital display vernier scale.
(2) background technology: at present, inner diameter measurement adopts measurers such as inside meter, micrometer inside caliper, internal caliber gauge to measure mostly.But the oil cylinder class is had the workpiece of dark and narrow groove, and its groove inner diameter measurement is just very inconvenient, and narrow because of groove, trough is dark, adopts inside meter, micrometer inside caliper, can't put in the groove and measure, and internal caliber gauge, the user is difficult to grasp, and error is big.The groove internal diameter is overproof, will cause product defective, and entire product is scrapped, and brings loss to enterprise.
(3) summary of the invention: the purpose of this utility model is exactly the problem that will solve oil cylinder gash depth dimensional measurement difficulty, and a kind of oil cylinder groove internal diameter digital display vernier scale is provided.
Concrete scheme of the present utility model is: utilize existing digital display pit gauge to be improved, it includes a digital display pit gauge, it is characterized in that: design has a bearing, the chi frame of digital display pit gauge adopts left and right sides briquetting screw retention to be installed on the bearing, the tail end design of bearing has boss, the adjustable sounding rod that extends back is installed on the boss, and the length of the blade of the center line of this adjustable sounding rod and digital display pit gauge is to the center line coaxial arrangement.
Process for convenience, the stability and the reliability of product is provided, the Front-end Design of bearing described in the utility model has rib, and the chi frame front end of digital display pit gauge and the rib of bearing are close to positioning and fixing.
The utility model compact conformation, easy to operate, quick, the measuring accuracy height.During use the two ends measurement point is made on the adjustable sounding rod top at digital display pit gauge head and bearing rear portion, stretched into and internal diameter is measured in the narrower groove of oil cylinder, the reading by the digital display pit gauge can make things convenient for reads the internal diameter error amount fast.The inside dimension (internal diameter, length) that the utility model also can be used for all kinds of workpiece is measured.
(4) description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the three-dimensional view of the utility model bearing;
Fig. 4 is the utility model user mode figure.
Among the figure: 1-blade, 2-screw, 3-briquetting, 4-chi frame, 5-boss, the adjustable sounding rod of 6-, 7-bearing, 8-rib, 9-oil cylinder.
(5) embodiment:
Referring to Fig. 1, Fig. 2, the utility model is directly bought digital display pit gauge one (being made up of blade 1 and chi frame 4), adopt steel part to make bearing 7 (referring to Fig. 3), Front-end Design at bearing 7 has rib 8, the tail end design of bearing 7 has boss 5 (boss 5 should guarantee certain adjustable range with the afterbody of blade 1, as 50mm), and boss 5 rear sides have screw, install the adjustable sounding rod 6 (adjustable sounding rod 6 can be equipped with many models different in size, to adapt to the different depth needs) that extends back.Adopt left and right sides briquetting 3 and screw 2 that the chi frame 4 of digital display pit gauge is fixedly installed on the bearing 7, and allow the rib 8 of chi frame 4 front ends and bearing be close to positioning and fixing, the length of blade 1 that keeps the center line of adjustable sounding rod 6 and digital display pit gauge simultaneously promptly constitutes the utility model to the center line coaxial arrangement.
The utility model using method is described as follows: referring to Fig. 4, outside micrometer is adjusted to drawing " tested groove dimensions D ", is that the benchmark zeroing (should be noted: before the zeroing with the utility model with outside micrometer " tested groove dimensions D ", the afterbody of blade 4 keeps enough retraction distances, internal diameter chi retraction size L＜cylinder sleeve finish dimensional d; So that the groove internal diameter digital display vernier scale after the half-angle zeroing is put into groove, the size of curtailment can be regulated with other adjustable sounding rod, to satisfy the drawing dimensional requirement).Blade after zeroing retraction launches after putting into the groove of oil cylinder 9, makes the tail end of the front end of blade 4 and adjustable sounding rod 6 contact the internal diameter data error value that just can read the groove of surveying at this moment with inwall on the trench diameter direction.Easy to operate, quick.
