Description
Technical field
The present invention relates to a kind of dimension measuring implement, particularly the dimension measuring implement of low height boss on a kind of measurement plane belongs to the size metering field.
Background technology
The measurer of measurement size commonly used has vernier caliper and milscale, and vernier caliper commonly used can be used for measuring length, internal-and external diameter, the degree of depth etc., and precision reaches as high as the hundredths of millimeter, and precision is lower, does not usually adopt when accurately measuring; Milscale commonly used, also be micrometer caliper, also can be used to measure length, external diameter etc., precision reaches as high as thousand minutes positions of millimeter, precision is higher, but because the gage button of milscale and to measure the screw rod cross section be the circle that certain diameter length is arranged, so when the length of boss highly less on the measurement plane or external diameter, because boss height is less, the gage button of milscale and screw rod block the two ends inconvenient operation of boss and cause easily measuring the certain error of generation.
Summary of the invention
The invention provides a kind of dimension measuring implement.Solved on the plane height than the problem of small boss length high-acruracy survey.
Technical scheme of the present invention is as follows:
A kind of dimension measuring implement comprises chi frame 1, fixedly gauge head 2 and movable gauge head 3; The chi frame is] or circular arc, fixedly gauge head 2 be fixedly connected on the inboard at chi frame 1 two ends with movable gauge head 3 and the upper end is highly consistent and the measurement of partner out yoke and opposite face between; Fixedly gauge head 2 comprises pole, fixedly chaining pin and fixing gage button, and fixedly gage button is spherical surface, and fixedly chaining pin is fixedly connected on the pole, and fixedly gage button is on the fixing top of chaining pin; Movable gauge head comprises bearing 4, movable chaining pin 5, movable gage button 6, dial gauge 7; Movable gage button 6 is on the top of movable chaining pin 5 and be spherical surface; Movable chaining pin 5 and dial gauge 7 have consisted of lever construction by bearing 4.
During small boss length, carry out the dial gauge zeroing with measurer measurement standard gauge block first on the measurement plane, and then measure land length, read the dial gauge reading this moment and be the length difference of land length and standard gauge block, can get land length thus.
Further, the hole that cooperates with movable gauge head bearing is arranged on the chi frame, movable gauge head is fixedly connected on the chi frame by clamping screw, by unscrewing clamping screw adjustable gauge head and the fixing relative distance between the gauge head;
Further, fixedly all studding with wimet on two measurement faces of gage button and movable gage button, making measurement face energy durable in use;
Further, the bearing seat is as the axial direction of cylindrical and seat body and porose and interpenetrate in the radial direction, two supports that are parallel to each other with seat body central shaft are arranged in the both sides of radial hole, the support upper end is porose, movable chaining pin center is porose, movable chaining pin is fixedly connected on the support by bearing pin and the lower end is stretched in the radial hole of bearing seat body, and movable chaining pin center pit and pin are clearance fit; The sleeve of dial gauge inserts in the seat body axial hole and forms interference fit with the hole, and end in contact forms lever construction under dial gauge gauge head and the movable chaining pin;
Further, according to the scope of measuring, there is certain pre-pressing amount dial gauge gauge head and movable chaining pin lower end;
Further, on the chi frame lightening hole is arranged;
Further, can replace dial gauge with clock gauge according to the measuring accuracy needs.
Effect of the present invention and benefit are:
Because the shape of chaining pin spherical surface thin and gage button is less, thus the external dimensions of highly less boss on can measurement plane, accurate positioning, measuring accuracy is high; Because zeroing function is arranged, so also can be used for measuring the tolerance relative value of fixed measure, reading is simple and reliable again, and it is convenient to measure, and raises the efficiency.
