As shown in Figure 1, the detection device 100 of embodiment according to the present utility model is mounted on axis 200 for detecting
The axial runout of sprocket wheel 201.
Detection device 100 includes support component.Support component is used for the pre-position support shaft 200 in axis 200, ability
Field technique personnel are it is understood that above-mentioned predetermined position is the design Support Position of spindle 200 during use.Referring to Fig. 1
Introduce support component.Specifically, as shown in Figure 1, support component includes axial in the first axis predetermined position of axis 200 and second
The the first V-type supporting block 101 and the second V-type supporting block 102 of predetermined position support shaft 200, also, axis 200 is pre- in first axis
Positioning, which is set, is rotatably supported at the first V-type supporting block 101 and the second V-type branch by bearing with the second axial pre-position
On bracer 102.
In addition, detection device 100 further includes baffle 103, one end of the separate sprocket wheel 201 of axis 200 is arranged in baffle 103
(that is, right end shown in Fig. 1).When axis 200 is by after first axis predetermined position and the second axial predetermined position support, will keep off
Plate 103 is placed on the right end of axis 200 to prevent axis 200 from moving right and changes scheduled axial Support Position.Moreover, detection
Device 100 further includes clamping component 104, and clamping component is used for one end of the close sprocket wheel 201 of clamp shaft 200 (that is, showing in Fig. 1
Left end out), after the right end that baffle 103 is placed on axis 200, left end clamp shaft 200 of the clamping component 104 in axis 200.Cause
This, when axis 200 is rotatably supported at the first V by bearing in first axis predetermined position and the second axial pre-position
After in type supporting block 101 and the second V-type supporting block 102, axis 200 is limited in by baffle 103 and 104 collective effect of clamping component
It is above-mentioned axial direction predetermined position and can not the right and left again in Fig. 1 move up.
Detection device 100 further includes detection components.Fig. 2 is the partial enlarged view of the part A of detection device in Fig. 1.Below
The detection components of the detection device of the utility model are introduced referring to Fig. 2.
As shown in Fig. 2, detection components include digital display dial gauge 105 and bounce receiving unit, digital display dial gauge 105 is fixed on inspection
It surveys on component, and is horizontally placed therefore in Fig. 2 due to digital display dial gauge 105 and can be used for what detection was contacted with its gauge head
Moving distance of the component in the horizontal direction in Fig. 2；Bounce receiving unit includes oscillating deck 106 and is arranged on oscillating deck 106
The contact jaw 107 contact with the tooth of sprocket wheel 201 high middle part, as shown in Fig. 2, oscillating deck 106 passes through pin, (it passes through in Fig. 2
The solid black circle of the upper end of oscillating deck 106 is schematically shown) detection device is rockably mounted to (for example, detection device
Framing component) on, the high middle part of the tooth of contact jaw 107 and each tooth of sprocket wheel 201 contacts, (this field skill of digital display dial gauge 105
Art personnel are not limited to it is understood that in detection device according to the present utility model using digital display dial gauge, in fact, it is possible to
Any displacement detection part for surveying movement of the detection oscillating deck in the axial direction of axis can be used, for example, digital display displacement sensor)
It is arranged in the first side left side of oscillating deck 106 (that is, in Fig. 2) of oscillating deck 106 and for detecting oscillating deck 106 in axis 200
Axial direction on movement, sprocket wheel 201 is arranged in second side opposite with the first side of oscillating deck 106 (that is, oscillating deck 106 in Fig. 2
Right side), when sprocket wheel 201 rotates, oscillating deck 106 successively move through each teeth portion of sprocket wheel 201 with contact jaw 107 and
It swings.Preferably, contact jaw 107 is ball contact end, it will be appreciated by those skilled in the art that contact jaw 107 is not limited to spherical shape
Contact jaw, or the contact for the other shapes that can be successfully moved between each tooth of sprocket wheel as sprocket wheel rotates
End, for example, cylindrical contact jaw.
The principle of the detection device of the utility model is, when the axial out of plumb of the end face of sprocket wheel 201 and axis, sprocket wheel
Position of the high middle part of the tooth of 201 each tooth on the axial direction of axis is different, therefore the tooth senior middle school with each tooth of sprocket wheel 201
The contact jaw 107 of portion's contact also can be in the different location in the axial direction of axis with the high middle part of the different teeth being in contact with it
Place, moves together so as to cause the oscillating deck 106 and contact jaw 107 connecting with contact jaw 107, and oscillating deck 106 has passed through
The pin of the upper end shown in figure 2 is fixed on detection means, and therefore, oscillating deck 106 will be when contact jaw 107 be mobile with pin
To pivot spot wobble (specifically, oscillating deck 106 is to swing in Fig. 2).It will be appreciated by those skilled in the art that oscillating deck
106 track when being swung by pivotal point of pin is one section of circular arc, when being swung using pin as pivotal point due to oscillating deck 106
Amplitude of fluctuation very little, the track of the one section of circular arc formed when can be swung regards the track of one section of straight line as.Digital display thousand divides
It is the amplitude that swings of pivotal point using the degree of the axial runout as sprocket wheel 201 that table 105, which measures oscillating deck 106 using pin,.
The detection process of the utility model is, so that sprocket wheel 201 rotates, working as showing on record digital display dial gauge 105 is connect
Then numerical value when contravention 107 is located between the first tooth and the second tooth of sprocket wheel 201 is shown on record digital display dial gauge 105
Numerical value ... when between the second tooth and third tooth that contact jaw 107 is located at sprocket wheel 201 steps be repeated alternatively until contact jaw 107
Again the first tooth of sprocket wheel 201 is touched, later, calculates the difference judgement of maximum value and minimum value that digital display dial gauge 105 is shown
The sprocket wheel 201 on axis 200 axial runout whether in the margin of tolerance of design.
Therefore the detection device of the utility model needs to apply certain power for axis so that the sprocket wheel rotation one on axis is enclosed i.e.
The axial runout of the sprocket wheel in detection axis is carved, the detection device of the utility model has the advantages that detection efficiency is high.In addition, this reality
Also have the advantages that low in cost, structure is simple and is easily installed with novel detection device.
As previously mentioned, although being illustrated in explanation by reference to exemplary embodiment of the attached drawing to the utility model,
But the utility model is not limited to above-mentioned specific embodiment, the protection scope of the utility model should by claims and its
Equivalents limit.
