Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of tool that knife bar upper aperture symmetry is measured, the base 10 that comprises level, base 10 is provided with the bearing 20 that supports knife bar 80, and the pick-up unit 40 that can level be inserted into the dial gauge installed 30 in knife bar 80 upper aperture 81, pick-up unit 40 is longitudinally connected to movably perpendicular on base 10 and the support 50 that can move horizontally along base 10, pick-up unit 40 comprises that cross section is the detection body 41 of " U " font, a sidewall that detects body 41 can be inserted horizontally in square hole 81, and dial gauge 30 is installed on another sidewall.The sidewall detecting in the present invention in body 41 insertion square holes 81 is that cross section is square, and the form accuracy of this sidewall is higher.During detection, first on a sidewall that detects body 10, fill dial gauge 30, another sidewall inserts in square hole 81, and by support 50, pick-up unit 40 is moved forward and backward, and writes down the indicating value on dial gauge, then by 180 ° of knife bar 80 upsets, the measurement that uses the same method again, the value of twice measurement poor, is square hole 81 amount to be processed, if the difference of the value of twice measurement is 0, illustrate that this square hole 81 meets symmetry.And pick-up unit 40 can longitudinally regulate height along support 50 in the present invention, can detect the knife bar 80 of different sizes.
Preferably, in the present invention, on bearing 20, along its end face, be longitudinally provided with the support slot 21 that cross section is " V " font, knife bar 80 is shelved in support slot 21.The knife bar 80 of different-diameter size can be carried for the support slot 21 of " V " font in cross section, and knife bar 80 is shelved on support slot 21 when interior, and the outer wall of knife bar 80 and support slot 21 two sides are tangent, can position knife bar 80, prevent knife bar 80 rollings or rock.
Further, also can on bearing 20 one end, arrange and prevent that knife bar 80 from stretching out the backstay 22 of bearing 20 ends.Knife bar 80 is placed on support slot 21 when interior, for making a sidewall that detects body 41 can be inserted into quickly and accurately in square hole 81, one end of knife bar 80 is resisted against on backstay 22, knife bar 80 is positioned, pick-up unit 40 just can be measured the symmetry of square hole 81 rapidly.
Preferably, by detecting body 41, connection strengthening rib 42 between the sidewall of dial gauge 30 and the diapire of detection body 41 is installed.Because dial gauge 30 is mounted on the end of detecting body 41 1 sidewalls, dial gauge 30 itself possesses deadweight, for avoiding this sidewall to be out of shape under the effect of dial gauge 30 gravity, make dial gauge 30 show the numerical value that should not show, to cause the measuring error of symmetry, can provide support power by reinforcement 42 oppose side walls and prevent that this sidewall that detects body 41 is out of shape.
Detection body 41 in the present invention can be longitudinally and horizontal direction regulate reposefully, specifically by be longitudinally connected with the first guide rail 61 sliding for detecting body 41 on support 50, the diapire that detects body 41 is connected on the first guide rail 61 by connecting two first slide blocks 62, on one of them first slide block 62, is connected with set lever 63.When body 41 to be detected moves to needed height, by set lever 63, detection body 41 is fixed on to this At The Height, with the knife bar 80 to corresponding size, detects.
The adjusting of horizontal direction is that two is parallel and perpendicular to the second guide rail 71 of bearing 20, one end of support 50 is connected respectively on two second guide rails 71 by connecting two second slide blocks 72 by installing on base 10.Make to detect body 41 and move forward and backward at two the second parallel guide rails 71, can guarantee to detect the stationarity that body 41 moves horizontally, prevent from detecting body 41 and rock or tilt and cause measuring error.
The beneficial effect of the tool that knife bar upper aperture symmetry is measured of the present invention is:
1, be inserted in the square hole of knife bar to a sidewall horizontal of the detection body by " U " font, and move forward and backward detection body, by detecting the difference reaction square hole of twice measured value of the dial gauge of installing on body, whether meet the accuracy requirement of symmetry, it is precisely convenient, simple to operation to measure;
2, bearing can position knife bar, can make pick-up unit rapidly the square hole on knife bar be measured, and work efficiency is high;
3, pick-up unit is adjustable, can measure the knife bars of different sizes, and the adjustment structure of pick-up unit is more steady, can not make pick-up unit produce to rock or deflection and the measuring error that causes.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on instructions, must determine technical scope according to claim scope.
