Abstract
The utility model relates to a rapid and convenient camshaft keyway symmetry detector, which comprises a base. The rapid and convenient camshaft keyway symmetry detector is characterized in that the upper end face of the base is provided with a groove, a lever dial gauge is fixed in the groove, and an adjusting bolt is arranged on the bottom of the groove. The utility model has the advantages of convenient manufacture, simple structure and easy operation, and can rapidly and accurately detect the work piece machining accuracy.
Description
(1) technical field: the utility model relates to a kind of pick-up unit, specifically is a kind of conveniently camshaft keyway symmetry pick-up unit, and this device also can be used for the detection of other class keyway symmetries.
(2) prior art: according to GB1958-80≤detection rules 〉=: the measurement of keyway symmetry is divided into section gauge and long to measurement, existing section gauge generally is to adopt locating piece, dial gauge, V-block to come subsidiary, utilize the method to measure, complicated operating process and inefficiency in the production scene.
(3) summary of the invention: the purpose of this utility model just provides a kind of conveniently camshaft keyway symmetry pick-up unit; This device is easy to make, and is simple in structure, and easy operating can detect the workpiece processing precision fast and accurately.
The utility model is camshaft keyway symmetry pick-up unit conveniently, has base, it is characterized in that: described base upper surface has a groove, at the groove internal fixation one lever indicator is arranged; At bottom portion of groove the adjusting bolt is housed.
The dog screw that is used for fixing lever indicator is housed respectively in the groove two sides.
Measuring process of the present utility model is exactly in fact to measure the distance of keyway two sides and shaft centre line.Since easy to make, simple in structure, easy operating, it is very convenient to use in real work, and detection time is short, and the accuracy height is practical especially.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, the 1-base, the 2-groove, the 3-lever indicator, the 4-dog screw, 5-regulates bolt, 6-key, 7-workpiece for measurement, 8-keyway.
(5) embodiment:
Referring to Fig. 1, the utlity model has base 1, described base upper surface has a groove 2, and the dog screw 4 that is used for fixing lever indicator 3 is housed respectively in the groove two sides, is equipped with at bottom portion of groove and regulates bolt 5.
Measuring method is as follows: earlier key 6 is inserted in the keyway 8 of workpiece for measurement 7, suitably adjust the height of regulating bolt 5 according to the workpiece height, dog screw is tightened with the truck dead lever clock gauge, can measure; After measuring on one side, the upset workpiece is surveyed another side again, reads the difference a of dial test indicator.Use formula f=(h/G) .a to calculate then, promptly get keyway symmetry error amount f.In actual production process, require keyway symmetry f according to drawing, with formula f=(h/G) .a, obtain a, then by the difference a of control lever indicator, reach the purpose of control keyway symmetry f.
Claims (2)
1. camshaft keyway symmetry pick-up unit conveniently has base, and it is characterized in that: described base upper surface has a groove, at the groove internal fixation one lever indicator is arranged; At bottom portion of groove the adjusting bolt is housed.
2. conveniently camshaft keyway symmetry pick-up unit according to claim 1 is characterized in that: the dog screw that is used for fixing lever indicator is housed respectively in the groove two sides.
