The detecting tool variable in the outer diameter can detect different diameters quickly and accurately, comprises a base and is characterized in that two ends of the lower portion of the base are provided with locating seats, a fixed measuring rod and a movable measuring rod are arranged between the locating seats in a corresponding mode, the fixed measuring rod is fixedly connected with the lower end of the base, the base is provided with a through groove, a measuring seat capable of sliding and an adjustable screw are arranged in the through groove, the adjustable screw fixes the measuring seat in the through groove, a stem-winder is arranged on the measuring seat, the movable measuring rod is connected with the measuring seat through a rotating shaft, one end of the measuring rod contacts with a measuring head of the stem-winder, and a spring is arranged between the movable measuring rod and the measuring seat.

Description

A kind of variable testing fixture for external diameter
Technical field
The present invention relates to the product detection field, be specially a kind of variable testing fixture for external diameter.
Background technology
The measurer that detects the workpiece external diameter is more, workpiece for some fixing sizes, can make the measurer of correspondingly-sized, but it can only detect the external diameter of fixed measure, the scope of measurement is little, and just can't detect for the workpiece of various outer diameter, generally can use vernier caliper to measure, and when workpiece size is larger, if make the vernier caliper of comparable size, its high cost, and inconvenient operation.
Summary of the invention
In order to address the above problem, the invention provides a kind of variable testing fixture for external diameter, it can detect different external diameters rapidly and accurately.
Its technical scheme is such: it comprises base, it is characterized in that, two ends, described base bottom are provided with positioning seat, be provided with corresponding fixation measuring bar and movement measuring staff between the described positioning seat, described fixation measuring bar is fixedly connected with the base lower end, be provided with groove on the described base, be provided with measuring seat and the adjustable screw of slip in the described groove, described adjustable screw is fixed described measuring seat in groove, be provided with stem-winder on the described measuring seat, described movement measuring staff is connected with described measuring seat by turning axle, described movement measuring staff one end contacts with the measuring head of described stem-winder, is provided with spring between described movement measuring staff and the described measuring seat.
It is further characterized in that, is provided with spherical measuring head on described fixation measuring bar and the described movement measuring staff.
After adopting structure of the present invention, two ends, base bottom are provided with positioning seat, be provided with corresponding fixation measuring bar and movement measuring staff between the positioning seat, the fixation measuring bar is fixedly connected with the base lower end, be provided with groove on the base, be provided with measuring seat and the adjustable screw of slip in the groove, adjustable screw is the fixation measuring seat in groove, be provided with stem-winder on the measuring seat, movement measuring staff is connected with measuring seat by turning axle, movement measuring staff one end contacts with the measuring head of stem-winder, be provided with spring between movement measuring staff and the measuring seat, owing to be provided with groove, measuring seat can be whole mobile in groove, thereby the change measurement range can detect different external diameters rapidly and accurately.
Description of drawings
Fig. 1 is structural front view of the present invention;
Fig. 2 is structure vertical view of the present invention.
Embodiment
See Fig. 1, shown in Figure 2, it comprises base 1, two ends, base 1 bottom are provided with positioning seat 2, be provided with corresponding fixation measuring bar 3 and movement measuring staff 4 between the positioning seat 2, fixation measuring bar 3 is fixedly connected with base 1 lower end, be provided with groove 5 on the base 1, be provided with measuring seat 6 and the adjustable screw 11 of slip in the groove 5, adjustable screw 11 is at groove 5 interior fixation measuring seats 6, be provided with stem-winder 7 on the measuring seat 6, movement measuring staff 4 is connected with measuring seat 6 by turning axle 8, movement measuring staff 4 one ends contact with the measuring head of stem-winder 7, are provided with spring 9 between movement measuring staff 4 and the measuring seat 6, are provided with spherical measuring head 10 on fixation measuring bar 3 and the movement measuring staff 4.
Its testing process is as described below: base 1 is positioned on the tested workpiece 12, behind positioning seat 2 location, detect by fixation measuring bar 3 and movement measuring staff 4, the swing of movement measuring staff 4 passes to the measuring head of stem-winder 7, stem-winder 7 readings are changed, stem-winder 7 readings are the external diameter of surveying, when needs are measured various outer diameter, unscrew adjustable screw 11, at groove 5 interior traverse measurement seats 6, when making distance between fixation measuring bar 3 and the movement measuring staff 4 reach required detection size, tighten adjustable screw 11, fix measuring seat 6, just can carry out the measurement of various outer diameter.
