Abstract
The invention relates to the field of product detection and particularly provides a bottom outer diameter gauge. The bottom outer diameter gauge can detect the outer diameter of the bottom of a workpiece rapidly and accurately, and the bottom outer diameter gauge comprises a base. The bottom outer diameter gauge is characterized in that two laterally corresponding standard bases are arranged on the base, a measuring base is arranged on the outer side of the right standard base, a movable measuring rod is arranged on the measuring base, one end of the measuring rod is connected with the measuring head, the measuring head penetrates through the right standard base, the other end of the measuring rod is connected with a mechanical watch through a spring, and a detachable calibration member is arranged between the two standard bases.
Description
Technical field
The present invention relates to the product detection field, be 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 are also arranged, inconvenience when positioning.
Summary of the invention
In order to address the above problem, the invention provides a kind of bottom testing fixture for external diameter, 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, two reference seat of correspondence about being provided with on the described base, described right reference seat arranged outside has measuring seat, be provided with movably sounding rod on the 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 the described base, and described stem-winder is installed on the described gauge stand; Described calibrating device comprises datum plate and location-plate, on the described location-plate handle is installed.
After adopting structure of the present invention, corresponding two reference seat about being provided with on the base, right reference seat arranged outside has measuring seat, be provided with movably sounding rod on the 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.

Fig. 2 is structure vertical view of the present invention;
Fig. 3 is the calibrating device structural front view;
Fig. 4 is calibrating device structure vertical view.
Embodiment
See Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, it comprises base 1, two reference seat of correspondence, i.e. left reference seat 2 and right reference seat 3 about being provided with on the base 1, right reference seat 3 arranged outside have measuring seat 4, be provided with movably sounding rod 5 on the measuring seat 4, sounding rod 5 one ends connect measuring head 6, and 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 the right reference seat 3, be provided with gauge stand 9 on the base, stem-winder 8 is installed on the gauge stand 9, calibrating device 10 comprises datum plate 12 and location-plate 11, and handle 13 is installed on the 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 the 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 the right reference seat 3 positions, no matter workpiece 14 bottoms are the plane whether, because the bottom does not contact base 1, workpiece 14 can both be positioned, measuring head 6 on the sounding rod 5 contacts with workpiece 14 bottom margins, by stem-winder 8 readings, judges whether up to specification; Handle 13 is installed on the location-plate 11 is convenient to operation calibration part 10.
