Detailed description of the invention
Fig. 1 is sectional view of the utility model for the mounting hole locating check fixture of gear-box.
Fig. 2 is top view of the utility model for the mounting hole locating check fixture of gear-box.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Refering to fig. 1 and Fig. 2, the utility model provide a kind of mounting hole locating check fixture for gear-box, have structure
Simply, easy to use, the features such as accuracy is high, solve the problems, such as that prior art measurement and positioning mounting hole error is big.It ties below
Mounting hole locating check fixture of the attached drawing to the utility model for gear-box is closed to be illustrated.
As depicted in figs. 1 and 2, the utility model for gear-box mounting hole locating check fixture include: a positioning substrate 10,
The round bump 21 on positioning 10 surface of substrate is protruded from, the detection hole 31 of positioning 10 surrounding of substrate is formed in and inspection can be arranged in
The detection bar 32 of gaging hole 31.Wherein, round bump 21 corresponds to the sleeve of gear-box side, and the maximum outside diameter of round bump 21
Equal to the internal diameter of the sleeve, the design position of detection hole 31 and gear-box side mounting hole is corresponded.
When round bump 21 is stuck in sleeve, detection hole 31 is directed at corresponding mounting hole, at this time where detection hole 31
Position is the reference for assembling of mounting hole, by will test bar 32 across detection hole 31 and protrude into corresponding mounting hole, to examine
Survey the position of mounting hole.Specifically, if detection bar 32 may pass through detection hole 31 and protrude into corresponding mounting hole, testing result
For mounting hole accurate positioning；And if having at least one detection bar 32 that can only protrude into detection hole 31 and corresponding installation can not be protruded into
Hole, then testing result is mounting hole locating bias, is not inconsistent standardization.
In a preferable embodiment, the rear end of detection bar 32 is equipped with a lever 33, holds the inspection convenient for testing staff
Measuring staff 32, and protruded into detection hole and corresponding mounting hole.And in another preferable embodiment, detection bar 32 is worn simultaneously
It is fixed in detection hole 31, testing staff makes detection bar protrude into corresponding mounting hole by running fix substrate.
Preferably, detection bar 32 is variable diameter rod piece, and the diameter of 32 front end of detection bar is less than the diameter of its rear end, to detect
The front end of bar 32 can swimmingly protrude into mounting hole.
As shown in Figure 1, positioning 10 center of substrate offers an installation through-hole, positioning piece is equipped in the installation through-hole
20, which is detachably mounted on positioning substrate 10, and the end of locating piece 20 protrudes from the surface of positioning substrate 10
And form round bump 21.Preferably, the front end of round bump 21 forms frustum cone structure, and the diameter of the frustum cone structure front end is less than
The diameter of its rear end, the i.e. outer diameter of 21 front end of round bump are less than the outer diameter of its rear end, convenient for round bump 21 is caught in gear
In the sleeve of case side.
Specifically, the one end (i.e. far from one end of gear-box) of locating piece 20 far from round bump 21 is screwed with a nut
22, since the outer diameter of round bump 21 and the outer diameter of nut 22 are all larger than the internal diameter of installation through-hole, pass through round bump 21 and spiral shell
Cap 22 is born against in two surfaces of positioning substrate 10, is realized locating piece 20 and is positioned being detachably connected for substrate 10, so that
The replaceable sleeve to be adapted to different gear-boxes of locating piece 20.Preferably, a gasket 24 is arranged on locating piece 20, gasket 24 pads
Between nut 22 and positioning substrate 10, and the internal diameter of gasket 24 adapts to locating piece 20, and it is logical that 24 outer diameter of gasket is greater than installation
The internal diameter in hole.
In a preferable embodiment, it is installed with spacing between round bump 21 and positioning substrate 10, so that locating piece
20 can slide along installation through-hole.A spring 23 is arranged on locating piece 20, spring 23 is set between round bump and positioning substrate,
The both ends of spring 23 are individually fixed in round bump 21 and position on opposite two surfaces of substrate 10, and spring 23 by compression and
Bear against its both ends in the surface of round bump 21 and positioning substrate 10.Under the action of spring 23, gasket 24 and nut
22 are held against in the surface of positioning substrate 10, and when round bump 21 be caught in sleeve it is interior after, leaned on if continuing that substrate 10 will be positioned
Nearly gear-box, then sleeve slides locating piece 20 along installation through-hole the force of locating piece 20, and spring 23 further compresses at this time, circle
Spacing between shape convex block 21 and positioning substrate 10 becomes smaller, and spacing is generated between nut 22 and positioning substrate 10, and completes inspection
After surveying and round bump 21 being exited sleeve, under the action of spring 23, gasket 24 and nut 22 are restored to and are resisted against positioning base
The state on 10 surface of plate.By the way that locating piece 20 to be mounted slidably, can voluntarily be adjusted when being detected using the locating check fixture
It saves round bump 21 and positions the spacing between substrate 10, to adapt to the sleeve of different depth.
Positioning 10 surrounding of substrate is installed with detection piece 30, and detection hole 31 is opened up on detection piece 30, and detection piece 30 protrudes out fixed
Position substrate 10 is close to the surface of gear-box.The side of said gear case refers both to the face that gear shaft is parallel on gear-box, the side
Upper usually there are four mounting holes, accordingly, as shown in Fig. 2, there are four detection piece 30 and its corresponding detection holes 31.
In conjunction with such as 1 and Fig. 2, when the mounting hole locating check fixture using the utility model for gear-box carries out detection work,
The hand-held positioning substrate 10 of testing staff makes round bump 21 be directed at gear-box side by the cubing close to the side of gear-box
After sleeve, moved to close to gear-box side, so that round bump 21 is caught in sleeve.Then, it will test hole 31 and be directed at gear
Mounting hole on case, and detection hole 31 is penetrated using detection bar 32, if four detection bars 32 may pass through detection hole 31 and protrude into
Corresponding mounting hole, then testing result is mounting hole accurate positioning；And if at least one detection bar 32 can only protrude into detection hole
31 and corresponding mounting hole can not be protruded into, then testing result be mounting hole locating bias.
Combine figure embodiment that the utility model is described in detail above, those skilled in the art can root
Many variations example is made to the utility model according to above description.Thus, certain details in embodiment should not constitute practical to this
Novel restriction, the utility model will be using the ranges that the appended claims define as the protection scope of the utility model.
