Preferably, the diameter of said place kick is identical with the corresponding diameter of said out star wheel alley arc section.
Preferably, said anchor clamps are through being bolted on the said measurement bay.
Preferably, has the stepped hole that the out star wheel shank wears on the said anchor clamps.
Preferably, said holding frame comprises joint pin, and the top of joint pin links to each other with said reference test bar, and the bottom of joint pin is provided with a circle groove of placing said place kick, in groove, is provided with a plurality of limited posts, and said place kick places between adjacent two limited posts.
Preferably, the bottom of said measurement bay is provided with supporting leg.
As stated, the out star wheel alley height of center measurement mechanism of the utility model has following beneficial effect: its simple in structure being convenient to is produced; Adopt place kick to contact with arc section; Realize fitting tightly of cambered surface and cambered surface, out star wheel circle drum bottom is a reference field, and the distance at this reference field and place kick center promptly can be as the fiducial value of out star wheel alley height of center measurement; Its measuring accuracy is high; Be easy to use, can measure the out star wheel of various models, improved production efficiency.

Embodiment
Below by the embodiment of particular specific embodiment explanation the utility model, be familiar with other advantages and effect that this technological personage can be understood the utility model easily by the content that this instructions disclosed.
See also Fig. 1 to Fig. 2.Notice; The appended graphic structure that illustrates of this instructions, ratio, size etc.; All only in order to cooperate the content that instructions disclosed, understanding and reading for being familiar with this technological personage, is not in order to limit the enforceable qualifications of the utility model; Event is the technical essential meaning of tool not; The adjustment of the modification of any structure, the change of proportionate relationship or size is not influencing under effect that the utility model can produce and the purpose that can reach, and the technology contents that all should still drop on the utility model and disclosed gets in the scope that can contain.Simultaneously; Quoted in this instructions as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc.; Also be merely be convenient to narrate clear, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment; Under no essence change technology contents, when also being regarded as the enforceable category of the utility model.
Like Fig. 1 and shown in Figure 2, the utility model provides a kind of out star wheel alley height of center measurement mechanism, comprises measurement bay 1; Measurement bay 1 is provided with dial gauge 2, lever 3 and the movable reference test bar 4 that is provided with, and an end of lever 3 and the gauge head of dial gauge 2 are conflicted, and the mark post 41 on the other end of lever 3 and the reference test bar 4 is conflicted; The bottom of reference test bar 4 is provided with holding frame 5,5 weeks of frame upwards is uniformly distributed with at least three place kick 6 in holding, under holding frame 5, is provided with the anchor clamps 7 that fixing out star wheel is used; Reference test bar 4 is located in also can be up and down on the measurement bay 1, and during measurement, out star wheel is fixed on the anchor clamps 7; Holding frame 5 stretches in the out star wheel, place kick 6 and out star wheel alley corresponding matching.The utility model adopts three place kick to locate the height of center of out star wheel alley; Because the out star wheel alley is made up of arc section and rectilinear end, arc section is positioned at the two ends of out star wheel alley, therefore; Adopt place kick to contact with arc section; Realize fitting tightly of cambered surface and cambered surface, out star wheel circle drum bottom is a reference field, and the distance at this reference field and place kick center promptly can be as the fiducial value of out star wheel alley height of center measurement.When measuring, at first the out star wheel standard component is fixed on the anchor clamps, carry out the standard adjustment, the reading of adjusting dial gauge this moment is zero; Once more out star wheel to be measured is fixed on the anchor clamps, reads the reading of dial gauge, in error range, out star wheel alley height of center then to be measured is qualified as if reading, if it is defective to exceed error range out star wheel alley then to be measured height of center.
As shown in Figure 2; Above-mentioned holding frame 5 comprises joint pin 51, and the top of joint pin 51 links to each other with reference test bar 4, and the bottom of joint pin 51 is provided with a circle groove 52 of placement positioning ball 6; In groove 53, be provided with a plurality of limited posts 52, place kick 6 places 52 of adjacent two limited posts.Be installation and the replacing that makes things convenient for place kick, above-mentioned groove 53 is surrounded by second limiting plate that first fixing on the joint pin 51 limiting plate and bolt are connected the joint pin bottom.Above-mentioned anchor clamps 7 are through being bolted on the measurement bay 1; Has the stepped hole that the out star wheel shank wears on the anchor clamps 7; Anchor clamps can the corresponding change with shape according to the size of survey out star wheel, makes the measurement mechanism of the utility model satisfy the measurement of various out star wheel alley height of centers.The bottom of measurement bay 1 is provided with supporting leg 8.
For improving measuring accuracy, the diameter of above-mentioned place kick 6 is identical with the corresponding diameter of out star wheel alley arc section, and different according to the survey out star wheel, place kick can be changed.
In sum, the out star wheel alley height of center measurement mechanism of the utility model, its simple in structure being convenient to is produced, but measuring accuracy is high, is easy to use, and can measure the out star wheel of various models, has improved production efficiency.So the utility model has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
