Abstract
Guide arm examines utensil relates to and examines the utensil field. Mainly be for solving the distance that detects the curved height of guide arm pressure and between guide arm centre bore and the vertical limit at present and waste time and energy, detect the low problem of precision and design. The measuring tool comprises a tool base, wherein a positioning hole is formed in the center of the lower surface of the tool base, the left end of a transverse coordinatometer is fixed on the tool base, the scale 0 of the transverse coordinatometer is aligned to the circle center of the positioning hole, a linear guide rail is fixed on the transverse coordinatometer, a sliding block is installed on the linear guide rail in a matching mode, and a longitudinal jackscrew is installed at the top of the sliding block; the longitudinal coordinatometer base is fixed on the sliding block, the longitudinal coordinatometer is in sliding contact with the longitudinal coordinatometer base, and the longitudinal coordinatometer base is provided with a transverse jackscrew. The vertical coordinatometer is provided with scales from top to bottom, and the distance between the position of the scale 0 of the vertical coordinatometer and the lower edge of the vertical coordinatometer is equal to the distance between the lower edge of the horizontal coordinatometer and the lower edge of the ruler base. The advantage is that it is high to detect the precision, labour saving and time saving.
Description
The technical field is as follows:
the utility model relates to an examine the utensil field, specifically be a detect utensil of examining of distance between detection guiding arm bending height and guiding arm centre bore and the vertical limit.
Background art:
at present, when the bending height of the guide arm and the distance between the center hole of the guide arm and the vertical edge are detected, the L-shaped clamping plate is used, the detection is inconvenient, time and labor are wasted, and the detection precision is low.
The invention content is as follows:
the utility model aims to solve the technical problem that a detection is easy is provided, detects utensil is examined to the leading arm that the precision is high.
The above object is achieved by: the measuring tool comprises a tool base, wherein a positioning hole is formed in the center of the lower surface of the tool base, the left end of a transverse coordinatometer is fixed on the tool base, the scale 0 of the transverse coordinatometer is aligned to the circle center of the positioning hole, a linear guide rail is fixed on the transverse coordinatometer, a sliding block is installed on the linear guide rail in a matching mode, a longitudinal jackscrew is installed at the top of the sliding block, and the sliding block can be limited by screwing the longitudinal jackscrew; the longitudinal coordinatometer seat is fixed on the sliding block, the longitudinal coordinatometer is in sliding contact with the longitudinal coordinatometer seat, the longitudinal coordinatometer seat is provided with a transverse jackscrew, and the longitudinal coordinatometer can be limited by screwing the transverse jackscrew.
The vertical coordinatometer is provided with scales from top to bottom, and the distance between the position of the scale 0 of the vertical coordinatometer and the lower edge of the vertical coordinatometer is equal to the distance between the lower edge of the horizontal coordinatometer and the lower edge of the ruler base.
The utility model has the advantages that: firstly, a pin is installed in a middle hole of a workpiece guide arm, a positioning hole of a ruler seat is sleeved on the pin, when the bending height A of the guide arm is measured, a transverse jackscrew is unscrewed to enable a longitudinal coordinatometer to move downwards to the upper surface of the right part of the guide arm, and the distance between the scale 0 of the longitudinal coordinatometer and the lower edge of the longitudinal coordinatometer is equal to the distance between the lower edge of the transverse coordinatometer and the lower edge of the ruler seat, so that the reading of the longitudinal coordinatometer is the bending height of the guide arm. When measuring distance B between guide arm centre bore and the vertical limit, the position of adjustment longitudinal coordinate chi makes its lower limb be less than a ruler base lower limb partly, then screws up horizontal jackscrew, unscrews vertical jackscrew, and the removal slider drives longitudinal coordinate chi and moves to ruler base direction, treats when longitudinal coordinate chi and the vertical limit contact of guide arm, screws up vertical jackscrew, and the reading of longitudinal coordinate chi and the contact department of horizontal coordinate chi this moment is the distance between guide arm centre bore and the vertical limit promptly. The device is used for detecting the bending height of the guide arm and the distance between the center hole of the guide arm and the vertical edge, and has the advantages of high precision, easy detection, time saving and labor saving.
