For a better understanding of the present invention, it is detected below with reference to Fig. 1 to Fig. 6 hob abrasion amount according to an embodiment of the present invention
Method and device is described in detail.
Fig. 1 shows a kind of flow diagram of hob abrasion detection method of the embodiment of the present invention.Hob abrasion inspection
Survey method is used to detect the abrasion loss of hobboing cutter, wherein hobboing cutter is in disk form, and the axial direction along hobboing cutter has the first side being oppositely arranged
And second side.Hob abrasion detection method includes：
Step S101：The setting flag at knife edge first pre-determined distance of first side away from hobboing cutter.
Step S102：Obtain the topography of hobboing cutter.
Wherein, topography includes the part edges edge of label and hobboing cutter.It therefore can accurately really by topography
Distance of the calibration note away from hobboing cutter edge.
Step S103：Actual range of the knife edge along the first preset direction to label is determined according to topography.
It is not limited here, preferred first preset direction is the radius of hobboing cutter to the specific set-up mode of first preset direction
Direction, when original state or hobboing cutter after a period of use, the distance for determining label to knife edge along radial direction can
The accurate abrasion loss for obtaining hobboing cutter, so that the difference between the initial distance and actual range that radial direction obtains more has
Reference value.Further first preset direction is radial direction in the horizontal direction, obtains label in the horizontal direction away from knife
The distance at sword edge operates simpler.
Step S104：The abrasion loss of hobboing cutter is determined according to the difference between initial distance and actual range.
Initial distance is distance of the knife edge along the first preset direction away from label under original state.Original state refers to rolling
Knife not yet uses, and the state not yet worn.
In embodiments of the present invention, the first side of hobboing cutter is provided with label, knife edge of the label away from hobboing cutter has the
One pre-determined distance, when blade is worn in hobboing cutter use process, distance of the knife edge away from label can change, and obtain
Can show the topography of knife edge to marking path under original state, analysis topography it can be learnt that knife edge away from
The initial distance of label；When hobboing cutter after a period of use, reacquire the topography of hobboing cutter, and pass through topography and determine
Actual range of the leading cutting edge edge far from label, compare the difference of initial distance and actual range it can be seen that hobboing cutter abrasion loss.
The present embodiment is by setting flag, and evaluation of markers determines the abrasion loss of hobboing cutter away from the distance between knife edge, and method is simple,
It is easy to operate, and the hobboing cutter distance of knife edge away from label before and after use can accurately be shown by setting flag, improve rolling
The measurement accuracy of knife abrasion loss.
Wherein it is possible to understand, label can be arranged directly on the outer surface or marking path hobboing cutter surface of hobboing cutter
With a certain distance, as long as marking path hobboing cutter side can be can show that from the topography for the hobboing cutter that the first side obtains
Edge has certain distance.Preferably, in the outer surface setting flag of hobboing cutter, simplify apparatus structure, at the same guarantee label and
The relative position of hobboing cutter is more stable, improves the accuracy of testing result.
It is not limited here, label can be one or more to the number of label, and when being labeled as one, label is in and rolling
The coaxial annular shape of knife；When labeled as multiple, label is spaced apart on the annulus coaxial with hobboing cutter, as long as passing through Local map
As can show that distance of the label away from knife edge, and under original state, mark the radial direction along hobboing cutter away from hobboing cutter blade
Edge being equidistant everywhere.Preferably, label is set to the outer surface of hobboing cutter, is labeled as one, and label is in and hobboing cutter
Coaxial annular shape, thus hobboing cutter itself topography everywhere obtained can clearly show that label away from knife edge away from
From, and under original state, it marks consistent at a distance from knife edge along radial direction.
Further, when label is arranged at hobboing cutter outer surface, label can protrude from the surface setting of hobboing cutter, Huo Zhezhi
Connect the outer surface that label is coated on to hobboing cutter.
Referring to Figure 2 together, in some alternative embodiments, step S102 includes：
Step S1021：Control hobboing cutter rotation.
Wherein, without limitation to the revolving speed of hobboing cutter.Preferably, it when hobboing cutter stabilization of speed, and can be obtained from topography
When actual range, start to obtain topography.The stabilization of speed of hobboing cutter, therefore when obtaining multiple topographies, control shooting
Device is at the uniform velocity taken pictures, easy to operate easy to implement, and the topography obtained is more clear accurately.When hobboing cutter revolving speed is steady
Topography that is fixed, and when can determine actual range in the topography shown on filming apparatus, i.e., being shown on filming apparatus
When middle label and knife edge imaging clearly, starts to obtain topography, make it possible to accurately analyze knife from topography
The initial distance or actual range of sword Edge Distance label.
Step S1022：The topography of hobboing cutter is obtained in pre-set interval.
In these optional embodiments, control hobboing cutter rotation obtains topography, so that obtaining figure in pre-set interval
The setting position of picture is constant, i.e., imaging region itself is constant, but hobboing cutter rotates, easy to operate, while making each office obtained
Portion's image is more stable, between each topography have it is comparative, facilitate carry out uniform data analysis.
Also referring to Fig. 3, in some alternative embodiments, further include after step S1021：
Step S1023：To pre-set interval throw light.

One step, so that the data analysis result carried out to topography is more accurate.
Referring to Figure 4 together, in some alternative embodiments, step S1023 includes：
Step S1023a：Parallel rays is projected from knife edge of second side into pre-set interval.
Step S1023b：From the first side to label throw light.
In these optional embodiments, parallel rays is projected from knife edge of second side into pre-set interval, so that
The imaging of knife edge is more clear from the topography that the first side obtains；From the first side to label throw light, so that from
The imaging marked in the topography that first side obtains is more clear.In the present embodiment, knife edge and mark in topography
Than more visible, the initial distance and actual range obtained from topography's analysis is more accurate for the imaging of note.
In some alternative embodiments, further include after step S1021：
Step S1024：Obtain N number of topography that hobboing cutter rotates one week.
Step S1025：Determine circularity of the knife edge along the second preset direction to pre-set interval edge in N number of topography
Distance.
Wherein, N is positive integer.The set-up mode of second preset direction it is not limited here, preferred second preset direction
For the radial direction of hobboing cutter, it is further preferred that the second preset direction is radial direction in the horizontal direction.
Step S1026：The deviation from circular from of hobboing cutter is determined according to N number of circularity distance.
In these optional embodiments, due to being to obtain topography in pre-set interval, obtained under original state
In each topography taken, distance of the edge of pre-set interval along the second preset direction apart from knife edge is almost the same；Work as rolling
Knife after a period of use, obtains hobboing cutter and rotates one week N number of topography, by comparing in N number of image knife edge along the
Distance X of two preset directions away from pre-set interval edge, can determine the deviation from circular from of hobboing cutter.When N number of X is different, and differ
When larger, illustrate that the deviation from circular from of hobboing cutter is larger.Therefore the abrasion loss of the present embodiment not only available hobboing cutter, can also obtain
The deviation from circular from of hobboing cutter.
