Abstract
A groove measuring apparatus comprises a workpiece (1), a support plate (2), a measuring rod (3), a spring (4), a central taper shaft (5), a sleeve (6), a microdrum (7) and a block pin (8). The apparatus is characterized in that the workpiece (1) is a to-be-measured workpiece and the right groove of the workpiece is a to-be-measured groove, the support plate (2) is arranged to the left of the sleeve (6), the measuring rod (3) is arranged in the upper and lower holes of the sleeve (6), the lower end of the measuring rod (3) is a conical surface smaller than or equal to 134 degrees, the spring (4) is arranged on the measuring rod (3), the central taper shaft (5) is arranged in the center of the sleeve (6), the conical surface (46 degrees) of the central taper shaft (5) contacts the lower conical surface of the measuring rod (3), the microdrum (7) is arranged on the right end of the central taper shaft (5), and the block pin (8) is arranged on the lower right portion of the sleeve (6) and has a limiting function.
Description
Technical field
The present invention relates to a kind of groove measurement mechanism, belong 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, object of the present invention, just in order to solve above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of groove measurement mechanism.
For solving the problem, the present invention is achieved by 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 invention has the beneficial effects as follows: 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 present invention with better enforcement, so it is not intended to limiting the invention, and all technical schemes taking equivalent replacement or equivalent transformation to obtain, all drop in protection scope of the present invention.
