Description

A kind of groove measurement mechanism
Technical field
The utility model relates to a kind of groove measurement mechanism, belongs to Machining Technology field.
Background technology
In Machining Technology, measure usual vernier caliper to the groove of some parts and measure, the dimensional accuracy measured like this is poor, carries out measuring the requirement just not reaching precision for high-precision part vernier caliper.Therefore a kind of groove measurement mechanism is designed very necessary.
Summary of the invention
For solving the problem, the purpose of this utility model is just in order to solve above-mentioned the deficiencies in the prior art, and the purpose of this utility model is to provide a kind of groove measurement mechanism.
For solving the problem, the utility model is achieved through the following technical solutions: a kind of groove measurement mechanism, be made up of workpiece 1, supporting plate 2, sounding rod 3, spring 4, the center axis of cone 5, sleeve 6, microdrum 7 and backing pin 8, it is characterized in that: described workpiece 1 is measured workpiece, its right groove is tested groove, described supporting plate 2 is installed on the left side of sleeve 6, and described sounding rod 3 is installed in the upper lower opening of sleeve 6, sounding rod 3 lower end is the conical surface≤134 0, described spring 4 is installed on sounding rod 3, and the described center axis of cone 5 is installed on sleeve 6 center, its conical surface is 46 0and with the lower taper-face contact of sounding rod 3, described microdrum 7 is installed on the right-hand member of the center axis of cone 5, and described backing pin 8 is installed on the right lower quadrant of sleeve 6, plays position-limiting action.Screw microdrum 7 during work, drive the center axis of cone 5 to be moved to the left, make the lower conical surface of the taper-face contact sounding rod 3 of the center axis of cone 5, make sounding rod 3 upwards contact the groove of workpiece 1, thus measure the degree of depth of groove.
The beneficial effects of the utility model are: a kind of groove measurement mechanism, the advantages such as structure is simple, measuring accuracy is high, easy to operate, cost is low, safe and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of groove measurement mechanism structural representation.
Embodiment
As shown in Figure 1, a kind of groove measurement mechanism, be made up of workpiece 1, supporting plate 2, sounding rod 3, spring 4, the center axis of cone 5, sleeve 6, microdrum 7 and backing pin 8, it is characterized in that: described workpiece 1 is measured workpiece, its right groove is tested groove, described supporting plate 2 is installed on the left side of sleeve 6, and described sounding rod 3 is installed in the upper lower opening of sleeve 6, sounding rod 3 lower end is the conical surface≤134 0, described spring 4 is installed on sounding rod 3, and the described center axis of cone 5 is installed on sleeve 6 center, its conical surface is 46 0and with the lower taper-face contact of sounding rod 3, described microdrum 7 is installed on the right-hand member of the center axis of cone 5, and described backing pin 8 is installed on the right lower quadrant of sleeve 6, plays position-limiting action.Screw microdrum 7 during work, drive the center axis of cone 5 to be moved to the left, make the lower conical surface of the taper-face contact sounding rod 3 of the center axis of cone 5, make sounding rod 3 upwards contact the groove of workpiece 1, thus measure the degree of depth of groove.
Below disclose the utility model with better enforcement, so itself and be not used to limit the utility model, allly take equivalent replacement or technical scheme that equivalent transformation obtains, all drop in protection domain of the present utility model.
