Description

A kind of dimension measuring implement
Technical field
The utility model relates to a kind of dimension measuring implement, and particularly the dimension measuring implement of low height boss on a kind of measurement plane, belong 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 due to the gage button of milscale with 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 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 easily cause measuring the certain error of generation.
The utility model content
The utility model provides a kind of dimension measuring implement.Solved on the plane height than the problem of small boss length high-acruracy survey.
The technical solution of the utility model 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 and movable gauge head 3 be fixedly connected on the inboard at chi frame 1 two ends and the upper end height is 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 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, first carry out the dial gauge zeroing with measurer measurement standard gauge block on 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 coordinates 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 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 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 seat body axial hole and forms interference fit with the hole, and under dial gauge gauge head and movable chaining pin, end in contact forms lever construction;
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 utility model and benefit are:
Thin and spherical surface gage button is less due to the shape of chaining pin, thus the external dimensions of highly less boss on can measurement plane, accurate positioning, measuring accuracy is high; Due to zeroing function being 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.
