Abstract

The invention relates to the product checking field, in particular to a self-locating outer diameter checking fixture which is capable of quickly and accurately checking the outer diameter. The self-locating outer diameter checking fixture comprises a U-shaped snap-gauge. A fixing measuring head is arranged at one end of an opening of the inner wall of the U-shaped snap-gauge. A movable measuring head corresponding to the fixing measuring head is arranged at the other end of the opening of the inner wall of the U-shaped snap-gauge. The movable measuring head is connected with a mechanical watch. Movable top rods are symmetrically arranged at two ends of the movable measuring head. The top rods are connected with the U-shaped snap-gauge through rod springs. A floatable support rod is arranged in the middle of the opening bottom of the U-shaped snap-gauge.

Description

A kind of self-align testing fixture for external diameter
Technical field
The present invention relates to the product detection field, be specially a kind of self-align testing fixture for external diameter.
Background technology
At mechanical field, the external diameter that detects workpiece generally can adopt vernier caliper, but is not easily when determining the center of circle, and for the workpiece external diameter of some fixed measures, if use vernier caliper, then detection efficiency is lower.
Summary of the invention
In order to address the above problem, the invention provides a kind of self-align testing fixture for external diameter, it can detect external diameter rapidly and accurately.
Its technical scheme is such: it is characterized in that, it comprises U-shaped clamp, described U-shaped clamp inwall opening part one end is provided with the fixation measuring head, the described U-shaped clamp inwall opening part other end is provided with the movable measuring head of corresponding described fixation measuring head, described movable measuring head connects stem-winder, described movable measuring head two ends are symmetrically arranged with mobilizable push rod, described push rod is connected with described U-shaped clamp by push rod spring, is provided with relocatable support bar in the middle of the described U-shaped clamp open bottom.
It is further characterized in that described stem-winder is connected described U-shaped clamp by gauge stand with clamp; Described support bar connects described U-shaped clamp by support spring.
After adopting structure of the present invention, U-shaped clamp inwall opening part one end is provided with the fixation measuring head, the U-shaped clamp inwall opening part other end is provided with the movable measuring head of corresponding fixation measuring head, movable measuring head connects stem-winder, movable measuring head two ends are symmetrically arranged with mobilizable push rod, push rod is connected with U-shaped clamp by push rod spring, be provided with relocatable support bar in the middle of the U-shaped clamp open bottom, tested workpiece is positioned in the U-shaped clamp, detects rapidly and accurately external diameter after by push rod workpiece being located automatically.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, it comprises U-shaped clamp 1, U-shaped clamp 1 inwall opening part one end is provided with fixation measuring head 2, the U-shaped clamp 1 inwall opening part other end is provided with the movable measuring head 3 of corresponding fixation measuring head 2, movable measuring head 3 connects stem-winder 4, movable measuring head 3 two ends are symmetrically arranged with mobilizable push rod 5, push rod 5 is connected with U-shaped clamp 1 by push rod spring 6, be provided with relocatable support bar 7 in the middle of U-shaped clamp 1 open bottom, stem-winder 4 is connected with clamp by gauge stand 8 and is connected U-shaped clamp 1, and support bar 7 connects U-shaped clamp 1 by support spring 10.
Its testing process is as described below: tested workpiece 11 is positioned in the U-shaped opening of U-shaped clamp 1, because movable measuring head 3 two ends are symmetrically arranged with mobilizable push rod 5, push rod 5 is connected with U-shaped clamp 1 by push rod spring 6, effect by spring force, the center of workpiece 11 can be automatically corresponding with the center of two push rods 5, be that fixation measuring head 2 and movable measuring head 3 just in time are positioned on the diameter of workpiece 11, reading by stem-winder 4 can quick and precisely detect external diameter, is provided with relocatable support bar 7 in the middle of U-shaped clamp 1 open bottom and plays a supporting role for workpiece 11.
