Description
Technical field
The utility model relates to the product detection field, is 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 utility model provides a kind of variable testing fixture for external diameter, and 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 described positioning seat, described fixation measuring bar is fixedly connected with the base lower end, be provided with groove on described base, be provided with measuring seat and the adjustable screw of slip in described groove, described adjustable screw is fixed described measuring seat in groove, be provided with stem-winder on 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, be provided with spring between described movement measuring staff and described measuring seat.
It is further characterized in that, is provided with spherical measuring head on described fixation measuring bar and described movement measuring staff.
after adopting structure of the present utility model, two ends, base bottom are provided with positioning seat, be provided with corresponding fixation measuring bar and movement measuring staff between positioning seat, the fixation measuring bar is fixedly connected with the base lower end, be provided with groove on base, be provided with measuring seat and the adjustable screw of slip in groove, adjustable screw is the fixation measuring seat in groove, be provided with stem-winder on 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 measuring seat, owing to being provided with groove, measuring seat can whole move in groove, thereby change measurement range, can detect rapidly and accurately different external diameters.
