Abstract
The utility model discloses a row pitch checking tool of fixed ball ring locating holes. The row pitch checking tool can rapidly and accurately check whether the row pitch of locating holes on a fixed ball ring accords with demands or not by the aid of the checking tool. The checking tool comprises a taper measuring head, wherein the lower end of the taper measuring head is connected with a connecting part, and the connecting part is fixedly connected on a meter pin of an inner diameter measuring instrument.
Description
Technical field
The utility model relates to and is used to detect the instrument of deciding pitch-row between the last pilot hole of Zhu Quan.
Background technology
When pearl circle product was decided in production, the pilot hole that processes was the benchmark of road, back brill, hinge, boring and milling operation, and the precision of pilot hole influences product quality.The means of general check pilot hole pitch-row are to use kind of calliper, and kind of calliper speed is slow, the size reflection is not directly perceived, measuring error is big, and the slide calliper rule cutting edge is easy to wear.Can measure two pilot hole pitch-rows whether in tolerance by means of internal diameter measuring instrument, whether meet the requirements to judge the pilot hole pitch-row.But the table leg structure of existing internal diameter measuring instrument is not suitable for deciding the pilot hole of Zhu Quan.
The utility model content
Technical problem to be solved in the utility model provides a kind of pitch-row cubing of deciding the pearl circle hole, can detect to decide whether the pilot hole pitch-row meets the requirements on the Zhu Quan quickly and accurately by means of this cubing.
The utility model comprises conical measuring head, connects a junction in the lower end of described conical measuring head, and described connecting portion is fixedly connected on the table pin of internal diameter measuring instrument.
Connect above-mentioned pilot hole cubing respectively on two table pin of internal diameter measuring instrument, two conical measuring heads are on same straight line, and are in one line.During detection, at first use and decide the zero-bit that pearl circle standard component is aimed at internal diameter measuring instrument, then two pilot holes of Zhu Quan to be determined are enclosed within respectively on the gauge head of two cones of internal diameter measuring instrument, the downward force a little at two measurement point edges, reading on the internal diameter measuring instrument is the tolerance value of two pilot hole pitch-rows, judges that thus two pilot hole pitch-rows are whether in margin tolerance.Because measuring head is cone shape,, decide whether the pilot hole pitch-row meets the requirements on the Zhu Quan thereby can detect quickly and accurately so can measure to the pearl circle hole of deciding in different apertures.
Preferably, described connecting portion is cylindrical.
Preferably, be connected by screw retention between the table pin of described columniform connecting portion and internal diameter measuring instrument.
Figure of description
Fig. 1 is the structural representation of pilot hole cubing;
Fig. 2 is that A among Fig. 1 is to view.
Embodiment
As depicted in figs. 1 and 2, pilot hole cubing in the present embodiment comprises conical measuring head 1, connect a columniform connecting portion 2 in the lower end of described conical measuring head 1, described columniform connecting portion 2 is fixedly connected on the table pin 4 of internal diameter measuring instrument by screw 3.
Connect above-mentioned pilot hole cubing respectively on two table pin of internal diameter measuring instrument, two conical measuring heads are on same straight line, and are in one line.During detection, at first use and decide the zero-bit that pearl circle standard component is aimed at internal diameter measuring instrument, then two pilot holes of Zhu Quan to be determined are enclosed within respectively on the gauge head of two cones of internal diameter measuring instrument, the downward force a little at two measurement point edges, reading on the internal diameter measuring instrument is the tolerance value of two pilot hole pitch-rows, judges that thus two pilot hole pitch-rows are whether in margin tolerance.
Claims (3)
1. pitch-row cubing of deciding the pearl circle hole is characterized in that: comprise conical measuring head, connect a junction in the lower end of described conical measuring head, described connecting portion is fixedly connected on the table pin of internal diameter measuring instrument.
2. pitch-row cubing of deciding the pearl circle hole according to claim 1, it is characterized in that: described connecting portion is cylindrical shape.
3. pitch-row cubing of deciding the pearl circle hole according to claim 2 is characterized in that: be connected by screw retention between the table pin of the connecting portion of described cylindrical shape and internal diameter measuring instrument.
