Detailed Description
Deep hole step height measurement device (fig. 3) comprises copper sheathing 1, body 2, measuring staff 3, percentage table 4, holding screw 5, spring 6 and stop screw 7. The dial indicator is used for amplifying the dimensional tolerance, the measuring rod 3 is extended into the measuring part, and the height difference is transmitted to the measuring head of the dial indicator 4 for measurement.
The measuring rod 3 is a stepped shaft and is positioned in the body 2, and the lower end part of the stepped shaft is parallel to the plane of the body 2 and is vertical to the axis;
a spring is arranged at the upper end of the stepped end surface of the measuring rod 3,
the copper bush 1 is positioned in the upper section of the body 2, the upper end and the lower end of the spring are respectively propped against the stepped end faces of the copper bush 1 and the measuring rod 3,
the limit screw 7 is positioned in the groove at the outer side of the large end of the measuring rod 3 and fixed on the body 2, and the limit screw 7 can move up and down relative to the measuring rod 3 in the groove to limit the up-down moving range of the measuring rod 3.
The opening structure of the copper sleeve 1 can clamp the shell of the dial indicator 4, and the copper sleeve 1 and the shell of the dial indicator 4 are fixed through the set screw 5.
The measurement mode is as follows (fig. 4):
after the device is assembled, the zero setting work is firstly carried out, the dial indicator 4 is moved up and down, the pointer of the dial indicator 4 has a certain reading number, the measuring head of the dial indicator 4 is attached to the upper surface of the measuring rod 3, the set screw 5 is fixed, the lower surface of the body 2 and the lower surface of the measuring rod 3 are attached to the platform, the dial indicator 4 is adjusted, the dial scale line '0' is overlapped with the pointer of the dial indicator 4, and at the moment, the zero setting of the whole device is finished. D, inserting the body 2 into the deep hole, wherein the lower surface of the body 2 and the workpiece 8 are in contact with each other1Surface fitting, due to the action of the spring 6, the measuring rod is pushed3 moving downwards, measuring rod 3 lower surface and workpiece 8D2The surface is attached and stops moving, and the reading of the pointer of the dial indicator 4 is read at the moment, so that whether the reading is within the tolerance range or not is judged.
