Abstract
The utility model relates to the field of product detection, in particular to a bottom outer diameter gauge which can detect the bottom outer diameter rapidly and accurately. The bottom outer diameter gauge comprises a base and is characterized in that two left-right corresponding reference bases are arranged on the base. A measuring base is arranged on the outer side of the right reference base, a movable measuring rod is arranged on the measuring base, a measuring head is connected to one end of the measuring rod and penetrates through the right reference base, the other end of the measuring rod is connected with a mechanical watch through a spring, and a detachable calibration element is arranged between the two reference bases.
Description
Technical field
The utility model relates to the product detection field, is specially a kind of bottom testing fixture for external diameter.
Background technology
Some round-disk shape workpieces, its bottom is generally the cylindrical of inside indentation, because it is highly lower, can't measure it during normal the placement, it generally all needing when external diameter detects bottom-up measurement the after its upset to be carried out, when this workpiece can not carry out rotary movement, just can't detect its external diameter, it is not the plane that some workpiece bottoms is also arranged, inconvenience when positioning.
Summary of the invention
In order to address the above problem, the utility model provides a kind of bottom testing fixture for external diameter, and it can detect the external diameter of workpiece bottom rapidly and accurately.
Its technical scheme is as described below: it comprises base, it is characterized in that, be provided with two reference seat corresponding to left and right on described base, described right reference seat arranged outside has measuring seat, be provided with movably sounding rod on described measuring seat, described sounding rod one end connects measuring head, and described measuring head passes described right reference seat, the described sounding rod other end connects stem-winder by spring, is provided with dismountable calibrating device between described two reference seat.
It is further characterized in that, is provided with gauge stand on described base, and described stem-winder is installed on described gauge stand; Described calibrating device comprises datum plate and location-plate, on described location-plate, handle is installed.
After adopting structure of the present utility model, be provided with the reference seat of corresponding two of left and right on base, right reference seat arranged outside has measuring seat, be provided with movably sounding rod on measuring seat, sounding rod one end connects measuring head, measuring head passes right reference seat, the sounding rod other end connects stem-winder by spring, first calibrating device is put stem-winder is calibrated, then tested workpiece is positioned on two reference seat and positions, need not workpiece is overturn, namely available sounding rod is measured, and detects rapidly and accurately the external diameter of workpiece bottom by the stem-winder reading.

Embodiment
see Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, it comprises base 1, be provided with two reference seat corresponding to left and right on base 1, be left reference seat 2 and right reference seat 3, right reference seat 3 arranged outside have measuring seat 4, be provided with movably sounding rod 5 on measuring seat 4, sounding rod 5 one ends connect measuring head 6, measuring head 6 passes right reference seat 3, sounding rod 5 other ends connect stem-winder 8 by spring 7, be provided with dismountable calibrating device 10 between left reference seat 2 and right reference seat 3, be provided with gauge stand 9 on base, stem-winder 8 is installed on gauge stand 9, calibrating device 10 comprises datum plate 12 and location-plate 11, handle 13 is installed on location-plate 11.
Its testing process is as described below: the location-plate 11 of calibrating device 10 is positioned on left reference seat 2 and right reference seat 3, sounding rod 5 stretches out, measuring head 6 and datum plate 12 edge contact, stem-winder 8 is calibrated, take calibrating device 10 away, tested workpiece 14 is positioned on left reference seat 2 and right reference seat 3 positions, no matter whether workpiece 14 bottoms are planes, because the bottom does not contact base 1, workpiece 14 can be positioned, measuring head 6 on sounding rod 5 contacts with workpiece 14 bottom margins, by stem-winder 8 readings, judges whether up to specification; Handle 13 is installed on location-plate 11 is convenient to operation calibration part 10.
