Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
As Figure 1-Figure 4, a kind of flatness detecting tool, including guide rail 1, percentage is installed on the guide groove 8 of guide rail 1
Table 3, dial gauge 3 slide along guide groove 8, and the bottom of guide rail 1 is provided with the reference plane 6 with plane contact to be detected, the bottom of guide rail 1
It is additionally provided with the groove 7 of cooling down of indent.In the present embodiment, plane to be detected refers to the upper plane of insert 5 to be detected, the bottom of guide rail 1
Reference plane 6 is smooth plane, and the plane and plane contact to be detected, the groove 7 of cooling down of indent play good gettering action, kept away
It is excessive and cause air-breathing to exempt from the contact area between the bottom of guide rail 1 and plane to be detected, and then avoids the bottom of guide rail 1 from sucking
In plane to be detected.Dial gauge 3 is height sensing dial gauge, can sense positive and negative values, i.e. dial gauge 3 can read positive negative value.
In the present embodiment, reference plane 6 is located at the both ends of the bottom of guide rail 1, and groove 7 of cooling down is between two reference planes 6 so that
Guide rail 1 can be contacted by reference plane 6 with plane stability to be detected, and certainly, reference plane 6 can also be with the bottom both ends of guide rail 1
Marginal existence a certain distance, reference plane 6 is parallel with sliding block 2, and then causes the line of travel of dial gauge 3 parallel to benchmark
Face 6, dial gauge 3 can accurately sense the flatness of plane to be detected.
Be provided with guide groove 8 can art skating sliding block 2, dial gauge 3 be arranged on sliding block 2 on.Sliding block 2 can be than smoothly
Ground slides in guide groove 8 is led, and by adjusting the height and position of height dial gauge 3, dial gauge 3 is sensed positive negative value
Sliding block 2 is provided with the mounting hole for being used for fixing dial gauge 3, and dial gauge 3 is locked at cunning by locking member 4 by mounting hole
On block 2.In the present embodiment, mounting hole includes the first mounting hole 21 of the table bar insertion for dial gauge 3, for the insertion of locking member 4
Second mounting hole 22, locking member 4 are bolt, and the second mounting hole 22 is provided with internal thread, and locking member 4 rotates into the second mounting hole
22, by the table rod locking in the first mounting hole 21.The aperture of first mounting hole 21 is more than dial gauge bar footpath 0.5mm so that percentage
Table 3 can be easily inserted in sliding block 2.Second mounting hole 22 is located at the side of sliding block 2, is specifically as follows M6mm screwed holes, bolt
Through screwed hole, dial gauge 3 is fixed on sliding block 2 by side lock clamp force.
Further, cool down the indent 1-2mm of groove 7, on the one hand, can play gettering action, on the other hand, moreover it is possible to effectively keep away
Exempt from location conflicts.The indent groove 7 that refers to cool down concaves towards side where guide groove 8.Hollow depth, which crosses conference, influences the intensity of guide rail,
It may occur necessarily to deform using rear rail 1 for a long time, also, detected plane is digital control processing face, flatness is poor
It is different smaller, generally within 0.5mm, so, 1~2mm of indent is fully sufficient.
Guide groove 8 is parallel to reference plane 6 so that dial gauge 3 can accurately sense the flatness of plane to be detected.
Preferably, the depth of parallelism≤0.02mm between guide groove 8 and reference plane 6 so that detection of the dial gauge 3 to flatness
With higher accuracy.
The rear and front end of the lower surface of sliding block 2 is provided with fillet, it is preferable that the radius of fillet is 2mm~3mm so that sliding block 2 can
Smoothly to be slided on guide groove 8, in the absence of location conflicts.
The width of guide groove 8 is bigger 0.04mm~0.06mm than the width of sliding block 2 so that guide groove 8 is in the width side of sliding block 2
Guide effect is played to sliding block 2, is rotated prevented also from sliding block 2.The width refers to the width perpendicular to the glide direction of sliding block 2.
The escape groove 9 positioned at the lower section of guide groove 8 is offered on guide rail 1, for preventing the table bar of dial gauge 3 from touching guide rail
1。
Preferably, the width of escape groove 9 is bigger 5mm~10mm than the table shank diameter of dial gauge 3 so that dial gauge 3 is in activity
During, its table bar will not touch guide rail 1.The width refers to the width perpendicular to the glide direction of sliding block 2.
As shown in figure 3, the guide groove 8 that sliding block 2 is bonded to guide rail 1 moves in one direction, from position A to position B, finally
Position C is moved to, the difference of reading maxima and minima is flatness tolerance.And guide rail 1 can be moved certain position, repeat
Above-mentioned detecting step, you can measure the flatness of other positions.
In summary, the utility model operating process is simple, energy quick detection flatness, is provided for quality inspection strong
Data supporting, and cost is relatively low, and each detection cycle is short, easy to use.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
God and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
