Abstract
The utility model relates to a measuring and positioning device, and belongs to the field of measurement and positioning auxiliary tools for center lines of a flange plate and a web of H-shaped steel. The measuring and positioning device comprises a positioner, a spiral regulator, a levorotation positioning rod, a dextrorotation positioning rod and a center calibrator. The measuring and positioning device is characterized in that the dimensions of the flange plate and the web of the H-shaped steel are measured via the adjustment of the telescoping of the levorotation positioning rod and the dextrorotation positioning rod by the spiral regulator, the centers of the flange plate and the web of the H-shaped steel are positioned by a V-shaped gap of the positioner, the positioning of the centers of the flange plate and the web of the H-shaped steel can be respectively realized without readings, the work efficiency is improved, and errors are reduced.
Description
Technical field:
The utility model relates to a kind of measurement and positioning device, belongs to H shaped steel flange plate and web central line measurement positioning auxiliaring tool field.
Background technology:
H formed steel construction is widely used in the manufacture of steel structure industry of multiple fields, using H shaped steel to carry out the link of processing and fabricating, inevitably need its web or flange plate to divert one's attention to process, general fashion is to calculate after steel tape is measured, measure line with calculated value again, while particularly line for web, the restriction of the knuckle while being subject to flange plate and flange plate and web rolling, be inconvenient to measure, thereby produce larger error.
Summary of the invention:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of measurement and positioning device is provided, to solve H shaped steel flange plate and web central line measurement orientation problem.
The purpose of this utility model is achieved in the following ways:
The utility model comprises a steady arm, a screw regulator, a left-handed backstay, a dextrorotation backstay and a calibrate device.It is characterized in that: left-right rotary screw rod is made respectively by unthreaded hole in the two ends, left and right of steady arm, and the center, two ends up and down of steady arm processing two v-notch, is line center; Steady arm inner side connects a screw regulator by left-right rotary backstay, and left-right rotary screw thread is made respectively at screw regulator two ends, a calibrate device of screw regulator center welding.
The utility model has the advantages that: be convenient to manual operation, reduce error, without reading, raise the efficiency.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is applied to H shaped steel flange plate schematic diagram.
Fig. 3 is that the utility model is applied to H shape steel web schematic diagram.
Embodiment:
The utility model comprises steady arm 1, screw regulator 2, left-handed backstay 3, dextrorotation backstay 4 and calibrate device 5.When application, first rotating screw regulator 2 makes left-handed backstay 3, dextrorotation backstay 4 be returned to calibrate device 5 to carry out calibrate, and the rotating screw regulator 2 of then outwarding winding makes left-handed backstay 3, dextrorotation backstay 4 outwards mobile respectively.Need be to H shape steel web center measurement and positioning time, the outermost end planar section of left-handed backstay 3, dextrorotation backstay 4 holds out against respectively both sides flange plate, and steady arm 1 center v-notch correspondence position is web center; Need be to H shaped steel flange plate center measurement and positioning time, the right-angle side part clamping flange plate two ends, inner side of left-handed backstay 3, dextrorotation backstay 4, steady arm 1 center v-notch correspondence position is flange plate center.
As a kind of measurement and positioning device, it should be noted that: the processing and fabricating of steady arm 1 center v-notch and calibrate device 5 first must be precisely, and left-right rotary backstay length dimension is definitely consistent the consistent also mutual coupling of all screw thread machined parameters.When application, note timely calibration.
Claims (1)
1. a measurement and positioning device, comprise a steady arm, a screw regulator, a left-handed backstay, a dextrorotation backstay and a calibrate device, it is characterized in that: unthreaded hole is made respectively at the two ends, left and right of steady arm, center, upper and lower two ends processes two v-notch, steady arm inner side connects a screw regulator by the left and right backstay that revolves, left-right rotary screw thread is made respectively at screw regulator two ends, a calibrate device of screw regulator center welding, v-notch and calibrate device are definitely placed in the middle.
