Abstract
The utility model relates to a comprehensive gauge for the shaft key slot symmetry. The utility model comprises a caliper section, a plug gauge section and a handle section. The minimum limiting dimension of the calipers is the same as the maximum limiting dimension of a basic shaft. The minimum limiting dimension of the key slot width minus the symmetry tolerance and then plus the tiny wearing quantity is equal to the minimum limiting dimension of the plug gauge. The gauge is suitable for the dimensional tolerance and the form and position tolerance, and is suitable for the situations adopting the relevant principles. The utility model has the advantages of quick measurement and convenient use. The work efficiency of the utility model is 11 times higher than the existing detection methods.
Description
The utility model relates to a kind of survey instrument, it is the receiver ga(u)ge that is used for by the shaft key groove symmetry error of correlation principle design.
Regulation according to " GB1183-80 shape and position of related features term and definition ", the symmetry definition of shaft key groove relative datum axis is: the central plane of keyway must be between distance be for two parallel planes of tolerance value, and this two plane symmetry is configured in the auxiliary plane both sides by datum axis.Current measuring methods is carried out according to " GB1958-80 shape and position of related features detect regulation ", measures by locating piece Simulation Center plane, is about to axis body and places on the platform on two contour vee-blocks, and make datum axis parallel with platform.Locating piece is placed in the keyway, rotation axis makes the plain line of locating piece parallel with platform, records keyway two ends difference in height h again
3-h
1, any part at keyway records height h again
2,, record height h at opposite side keyway any part then with axle Rotate 180 °
4, can draw the symmetry error value by calculating.
The shortcoming of this measuring method is: it is many that (1) detects man-hour, and generally detecting a middle size motor axle needs two people to work two hours, i.e. in four man-hours, labour intensity is big; (2) detect data and actual error gap is arranged; (3) can only after completion, detect,, also can't save if the workpiece symmetry is defective; (4) common key connection majority is the occasion that is used to satisfy matching property or assembling interchangeability, and this class occasion form and position tolerance is used correlation principle more, and existing method fails to embody this situation.
The purpose of this utility model provides a kind of symmetry that is suitable for and defines, satisfies correlation principle, detects easy symmetry receiver ga(u)ge.
The utility model is design like this: it comprises calliper, feeler gauge and handle.Calliper partly becomes a shape, feeler gauge partly becomes rectangular plate shape, be positioned at central authorities' (the relative calliper center line of feeler gauge symmetry reaches workpiece symmetry 15%) of calliper, the minimum limit of size of calliper equals the maximum limit of size of the benchmark diameter of axle, and the minimum limit of size of feeler gauge equals the wide minimum limit of size of keyway and subtracts the symmetry tolerance and add micro-wear extent.
Design concept of the present utility model is the definition according to shaft key groove symmetry tolerance, and for a groove depth h, straight length is the keyway of l, and its symmetry tolerance range is the rectangular parallelepiped of a t * h * l, and t is the symmetry tolerance value.The central plane of keyway can change in the tolerance range scope, possible relative datum axis deviation, skew or not only deflection but also be offset, and two sides of keyway are then changing in the tolerance range scope accordingly separately.Deduct the feeler gauge of symmetry tolerance value if get width for the keyway minimum limit of size, then this measurer is to satisfy the design that the symmetry tolerance adopts correlation principle.Use this feeler gauge and detect keyway, if can pass through on total length, and the feeler gauge end contacts with bottom land, and feeler gauge end face and bottom land have common angle on two end cross-sectional, and then this shaft key groove symmetry is qualified.
The utility model is suitable for only requiring the keyway measurement of satisfying assembling interchangeability, i.e. the place of design drawing mark symmetry employing correlation principle,
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is tolerance range schematic diagrams of the present utility model.
Accompanying drawing 3 is the control gauge synoptic diagram.
With reference to the accompanying drawings, receiver ga(u)ge comprises calliper 1, feeler gauge 2, handle 3.1 one-tenth of calliper door shape, the minimum limit of size of dimension D is got the maximum limit of size of the diameter of axle, 2 one-tenth rectangles of feeler gauge, its minimum limit of size equals the wide minimum limit of size of keyway and subtracts the symmetry tolerance and add micro-wear extent.Feeler gauge 2 can be made one with calliper 1, and makes feeler gauge 2 and calliper 1 workplace in one plane.Easy to make in order to make, also can make respectively, rivet then or be threaded and be integral.Handle 3 is connected with calliper 1.
If the utility model is produced in batches, need do a control gauge, the installation site of proofreading and correct feeler gauge 2 with control gauge when assembling or during reconditioning.D ' is identical with the calliper working size for control gauge concavity out-to-out, and B ' is identical with the feeler gauge working size for the inside groove size.
The utility model is as process inspection and the finished product inspection of machining keyway, can distinguish exactly the whether qualified of part, and gauge is simple in structure, easy to manufacture, easy to use, worn and torn with of a specified duration, the feeler gauge end can sharpening, long service life improves 10 times of work efficiency than present detection method.
Claims (3)
1, a kind of shaft key groove symmetry gauge, it comprises calliper, feeler gauge and handle, it is characterized in that: calliper becomes door shape, feeler gauge becomes rectangular plate shape, be positioned at the central authorities of calliper, with the calliper workplace in one plane, the minimum limit of size of calliper equals the maximum limit of size of the benchmark diameter of axle, the minimum limit of size of feeler gauge equals the wide minimum limit of size of keyway and deducts the symmetry tolerance, adds micro-wear extent.
