Abstract
The utility model relates to a measuring tool, concretely to a hole depth measuring instrument, which is characterized by comprising a connecting seat, a steel ball core rod inserted from the bottom of the connecting seat, a position stopping bolt inserted into the side wall of the connecting seat, a position return spring sleeved on the steel ball core rod, and an indicating gauge inserted from the connection seat and bearing against the upper end surface of the steel ball core rod, wherein a notch is arranged at the outer circle of the steel ball core rod, the end part of the position stopping bolt enters the internal of the connecting seat and is positioned in the notch of the steel ball core rod, one end of the position return spring contacts the bottom of the connecting seat, and the other end contacts the end part of the position stopping bolt. Compared with the hole depth measuring instrument in the prior art, the hole depth measuring instrument of the utility model has the following characteristics that the indicating gauge is proofread to zero, then the steel ball core rod is inserted into the deep hole of a part, the depth value of the hole can be immediately displayed on the indicating gauge, the operation is simple, and the disadvantage of low precision of a central hole during a product processing procedure can be solved.
Description
Technical field
The utility model relates to a kind of measurer, is exactly a kind of hole depth measuring instrument specifically.
Background technology
In present industry, the big or small degree of depth of traditional part center pit is always by kind of calliper, and not only measuring speed is slow to adopt the hole depth that this mode measures, and low precision.For the more fast and accurate big or small degree of depth of measuring center pit, need provide a kind of novel measuring equipment.
Summary of the invention
The utility model provides a kind of hole depth measuring instrument in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of hole depth measuring instrument, it is characterized in that: comprise Connection Block, and the steel ball plug that inserts from the Connection Block bottom, offer notch on the cylindrical of steel ball plug, also comprise the stop bit screw that inserts the Connection Block sidewall, the end of stop bit screw enters Connection Block inside, be positioned at the notch of steel ball plug, also comprise the retracing spring that is set on the steel ball plug, an end of spring contacts with the bottom of Connection Block, and the other end contacts with the end of stop bit screw, also comprise a dial gauge, the thimble of dial gauge inserts the upper surface of withstanding the steel ball plug from the top of Connection Block.
The utility model is compared with prior art, as long as the check and correction dial gauge is inserted into the steel ball plug in the deep hole of part to zero-bit then, the depth value in its hole can show at dial gauge at once, easy and simple to handle, solve product and added the not high shortcoming of center pit precision in man-hour.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1,1 is Connection Block; 2 is the steel ball plug; 3 is notch; 4 is the stop bit screw; 5 is retracing spring; 6 is dial gauge; 7 is calibrated bolck.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises Connection Block 1, and the steel ball plug 2 that inserts from the Connection Block bottom, offer notch 3 on the cylindrical of steel ball plug 2, also comprise the stop bit screw 4 that inserts Connection Block 1 sidewall, the end of stop bit screw 4 enters Connection Block 1 inside, be positioned at the notch 3 of steel ball plug 2, also comprise the retracing spring 5 that is set on the steel ball plug 2, one end of spring contacts with the bottom of Connection Block 1, the other end contacts with the end of stop bit screw 4, also comprises a dial gauge 6, and the thimble of dial gauge 6 inserts the upper surface of withstanding steel ball plug 2 from the top of Connection Block 1.
Specific operation process is as follows.
Prepare a calibrated bolck 7 that has deep hole earlier in advance, and record the degree of depth in its hole, steel ball plug 2 with dial gauge 6 inserts in the deep hole of its calibrated bolck 7 then, then dial gauge 6 is proofreaded to zero-bit, in the deep hole that is inserted into part with its dial gauge 6, the depth value in its hole can accurately show on dial gauge 6 again.Not only easy and simple to handle, and solved product and add the not high shortcoming of center pit precision in man-hour.
