Description
Technical field
The utility model belongs to a kind of measurement mechanism, is specifically related to a kind of lever measurement by magnification device.
Background technology
At present, detect part length deviate or school to turn the right alignment of part, the depth of parallelism, dial gauge is generally used to measure during the linear measure longimetry for Geometrical Error and thin tail sheep such as verticality, and the scale division value of existing dial gauge is 0.01mm, degree of accuracy after causing it to measure can only reach 0.01mm, can not be improved it again and detect degree of accuracy, and when measuring identical parts, each part needs repetitive operation, cause expending time in when often measuring a product very long, be unfavorable for the mass detection instrument as Product processing on Product processing line.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of lever measurement by magnification device, can improve measuring accuracy and be convenient to carry out mass detection to part.
For achieving the above object, the utility model provides a kind of lever measurement by magnification device, its key is: comprise pedestal and detection platform, described pedestal is connected with support, this support is positioned at the top of pedestal, described support is provided with lever and dial gauge, described lever to be hinged on support and horizontal positioned, one end of this lever is galianconism, the other end is long-armed, described galianconism end is provided with vertical measuring head down, and this measuring head is for contacting the uper side surface of part to be measured in described detection platform, described dial gauge is positioned at the below of described long arm end, and gauge head on this dial gauge vertically upward and correspondingly to contact with long-armed, describedly long-armedly be greater than 2 with the lenth ratio of galianconism.
Adopt technique scheme: when lever is in level, arrange detection platform face to the galianconism end of lever measuring head between distance be that the calibrated altitude of part is poor, when detecting part, part is placed on when detection platform detects, part top can contact with measuring head and drive lever rotation, can be read by the dial gauge below lever short arm, lower deviation value, owing to being lever amplification, so the numerical value of the dial gauge number of degrees is amplified by equal proportion, again divided by amplification coefficient, in fact lower deviation value just can be detected, and when amplification coefficient is higher, it is larger that its dial gauge high scale value is exaggerated multiple, measuring accuracy is higher, simultaneously by calculating the qualified numerical intervals that can draw on dial gauge, only detection part need to be placed in detection platform and to aim at measuring head, just can improve the error range that centimeter check goes out part fast, can judge that whether part is qualified fast, be convenient to carry out mass detection to part, simple to operate, have and can ensure product quality, improve detection efficiency, reduce the advantages such as testing cost.Same principle, on this device can also for measuring right alignment on part, the depth of parallelism, verticality, circle are beated etc. for Geometrical Error value.
As preferably, described long-armed be 5 ~ 20 with the lenth ratio of galianconism.Have employed larger amplification coefficient, rationally improve accuracy of detection, have simultaneously and whole lever can not be caused oversize and take too large space.
As preferably, described long arm end is larger than the weight of galianconism end.During detection, be in all the time and the gauge head contact condition on dial gauge on the downside of the galianconism that can ensure lever, guarantee to measure numerical value more reliable, and be convenient to lever rotation and be reset to original horizontal position.
Further, jacking block is provided with directly over described lever rotation center, this jacking block is movably hinged on the bracket, the upper end at described lever rotation center has towards " V " shape recess of described jacking block, it is protruding that described jacking block is provided with " V " shape corresponding with " V " shape recess, and the pinnacle of being somebody's turn to do " V " shape projection is inserted into described " V " v notch v point end and contacts with each other.Due to certain interval can be had between rotation axis and rotation hole during lever rotation, so adopt this structure, on jacking block, the pinnacle of " V " shape projection to be inserted in lever rotation overcentre " V " v notch v and to contact with the point end, lever rotation center pit upper side wall and rotating shaft is just made to keep in touch, rotation axis and the rotation hole tolerance clearance between all directions can be kept to be consistent, rotation axis and rotation hole is avoided on lever to cause relatively large deviation due to play or vibrations, improve product and measure reliability accurately, also avoid the measurement standard disunity between bulk article simultaneously.
Further, described support is provided with upper limit bar and lower limit bar, described upper limit bar is positioned at top corresponding to described long arm end, described lower limit bar is positioned at below corresponding to described long arm end, and described upper limit bar and lower limit bar have respectively and describedly long-armedly rotate up and down ultimate value for limiting.Because the rotation of lever long arm end and galianconism is just measured effectively in certain possible angle, just require that the upper and lower deflection angle of lever rotation can not be too large, so limited the upper and lower deflection angle of lever by upper limit bar and lower limit bar, regulations and parameters scope can only be rotated in certain possible angle, ensure that the reliability detecting numerical value.
Further, described support is provided with dial gauge fixed mount, described dial gauge position-adjustable is arranged on dial gauge fixed mount.When detection platform face to the galianconism end of lever measuring head between distance be that the calibrated altitude of part is poor, also to ensure that dial gauge number of degrees value is 0 simultaneously, before the first measurement of part, adjustment must be carried out to the height and position of dial gauge to revise and calibration, just can better ensure the accuracy measured.
Further, the top of described dial gauge fixed mount is provided with orienting lug, and described dial gauge sounding rod is straight up through the pilot hole on described orienting lug.Convenient when installing dial gauge, the sounding rod direction of energy quick position dial gauge, fast and easy is changed and is installed, and can improve and install degree of accuracy, also improve the reliability of this pick-up unit.
Further, described pedestal is provided with at least one lifting column, described support installing, in the upper end of described lifting column, is configured with the driving mechanism for driving described lifting column to move up and down in described lifting column.When the height detecting part is different, can this lifting column be passed through, realize the height of upper and lower adjustment detection head, can conveniently detect different part.
Beneficial effect is: the utility model structure is simple, easy to operate, can measuring accuracy be improved and be convenient to carry out mass detection to part, simple to operate, measurement efficiency is high, ensure that following process and the installation quality of workpiece, can meet the measure batch requirement of part preferably, enhance productivity, reduce production cost.
