Abstract
The utility model discloses an involute internal spline length bar span (M value) gauge, which comprises a gauge body (1), length bars (2) and a handle (3), wherein the gauge body (1) is a shaft section, the left end of the gauge body (1) is a no-go end and the right end of the gauge body (1) is a go end. Two length bars (2) are respectively and axially arranged on the external surfaces of the left part and the right part of the gauge body (1). The tails of the length bars (2) are clamped in annular tool withdrawal grooves in the external surface of the middle part of the gauge body (1). The handle (3) is in a sleeve-shaped structure. The handle is fixedly sheathed at the middle part of the gauge body (1). The handle (3) is sheathed outside the tail of the length bar (2). The involute internal spline M value gauge has the advantages that whether the M value of an involute internal spline is acceptable or not can be rapidly and conveniently detected, the defects of slow detection speed and non-intuitiveness of the traditional detection method are better overcome, the gauge is particularly suitable for large-scale detection, the structure is simple and the implementation is easy to conduct.
Description
Technical field
The utility model relates to a kind of measurer of measuring involute inner spline, specifically, relates in particular to involute inner spline M value gauge.
Background technology
At present, need detect after the involute inner spline processing, and involute inner spline length bar span (being called for short the M value) is an important detected value.Now the measuring method of M value is: two identical length bars of size are put into female spline respectively at a distance of farthest two teeth groove, survey the ultimate range between the side bus in two length bars with vernier caliper or gauge block again, this is apart from being the M value; We compare the tolerance value of M value that records and product permission, if the M value drops in the margin tolerance, then the M value of product is qualified, otherwise the M value of product is defective.Adopt said method to measure the M Value Operations inconvenience of involute inner spline; And then utilize the M value that records to come the M value of testing product whether qualified not directly perceived again; And detection speed is slow, efficient is low, and this defective is especially outstanding in mass detection, is badly in need of solving the problems of the technologies described above for this reason.
The utility model content
The utility model technical matters to be solved be to provide a kind of can fast detecting involute inner spline M value whether qualified gauge.
The technical scheme of the utility model is following: a kind of involute inner spline M value gauge; It is characterized in that: comprise gauge body (1), length bar (2) and handle (3); Wherein gauge body (1) is a shaft part, and its left end is a not-go-end, and right-hand member is the go side; And the outside surface that gauge body (1) is left and right is provided with two said length bars (2) respectively vertically, and the afterbody of this length bar (2) snaps in the annular relief groove on the outside surface of gauge body (1) middle part; Said handle (3) is a sleeve-like structure, and this handle is solidly set on gauge body (1) middle part, and handle (3) is enclosed within the outside of said length bar (2) afterbody.
The lower deviation of the size of this gauge go side and involute inner spline M value tolerance adapts, and the upper deviation of the size of not-go-end and involute inner spline M value tolerance adapts.Whether qualified use this gauge to detect the M value of involute inner spline when, internal splined hole can be filled in the go side that needs only gauge, and the not-go-end of gauge can not be filled in internal splined hole; The M value that is the decidable involute inner spline is qualified, otherwise is judged to be defective, simple to operation, directly perceived; Detect quick, convenient, overcome preferably the traditional detection method detection speed slowly, defective intuitively not, be specially adapted to mass detection; And it is simple in structure, easy to implement.
Said handle (3) is fixing with gauge body (1) through the screw (4) that radially is provided with, and so just can change the length bar after the wearing and tearing easily and quickly.
As optimization, left and right of said gauge body (1) is flat square shaft section, said length bar (2) is set on the plane of this flat square shaft section.
For the ease of discerning the not-go-end of this gauge, the left part of said handle (3) has the not-go-end indicator groove (3a) of annular.
Beneficial effect: whether the M value that the utility model can detect involute inner spline fast, easily qualified, overcome preferably the traditional detection method detection speed slowly, defective intuitively not, be specially adapted to mass detection, and simple in structure, easy to implement.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like Fig. 1, shown in 2, the utility model is made up of gauge body 1, length bar 2, handle 3 and screw 4, and wherein gauge body 1 is a shaft part, and its left end is a not-go-end, and right-hand member is the go side.The outside surface of said gauge body 1 left part and right part is provided with two said length bars 2 respectively vertically, and the afterbody of this length bar 2 snaps in the annular relief groove on the gauge body 1 middle part outside surface.As optimization, the left part of said gauge body 1 and right part all are processed into flat square shaft section, and said length bar 2 is set on the plane of this flat square shaft section.Simultaneously, the upper deviation of the size of gauge body 1 not-go-end and M value tolerance adapts, and the lower deviation of the size of gauge body 1 go side and M value tolerance adapts.In addition, for the ease of the screw that is connected with screw 4 on the processing gauge body 1, the spy has fabrication hole 1a vertically in the center of gauge body 1 right part, and this fabrication hole 1a is a blind hole.
Can find out that from Fig. 1,2 said handle 3 is a sleeve-like structure, this handle 3 is solidly set on the middle part of gauge body 1, and handle 3 is enclosed within the outside of said length bar 2 afterbodys.As optimization, said handle 3 is fixing with gauge body 1 through the screw 4 that radially is provided with, and the left part of handle 3 has the not-go-end indicator groove 3a of annular.Simultaneously, handle 3 is provided with the reticulate pattern 3b that is used to increase friction force.
The above is merely the preferred embodiment of the utility model; It is not restriction with the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
