Description

Aperture measuring tool
Technical Field
The present invention relates to a measuring tool, in particular an aperture measuring tool.
Background
When the high-precision hole part is machined by a special machine tool, the size of the part hole is required to be measured for multiple times in the first part trial machining process until the size of the hole reaches the design requirement, and then the batch machining can be performed after the sizes of the hole diameters of the parts are machined in the state to be stable. However, the length of the conventional internal diameter measuring gauge is too long to be measured due to the limitation of machine tool space. Special measuring tools need to be designed.
Disclosure of Invention
The invention aims to design an aperture measuring tool which has high precision and can measure on a machine tool.
The technical scheme for realizing the purpose of the invention comprises a dial indicator and a measuring gauge, and is characterized in that: the measuring gauge comprises a measuring shaft, a base body and a measuring rod, wherein the measuring shaft is respectively arranged in a transverse hole in the base body in a sliding mode, a spring is arranged between the left measuring shaft and the right measuring shaft, a connecting plate is connected with the outer end of the right measuring shaft, holes tightly matched with a pin are formed in the front portion and the rear portion of the connecting plate, a steel ball is arranged at the outer end of the pin, the outer end face of the left measuring shaft is a hemispherical face, a locating plate is arranged on the right upper surface of the base body, the centers of the front steel ball and the rear steel ball on the connecting plate are parallel to the plane where the centers of the hemispherical faces of the outer ends of the left measuring shaft are located, a handle is arranged on the right upper surface of the body, a meter frame is fixed on the upper surface of the left end of the base body, a transverse long hole is formed in the upper portion of the base body between the handle and the meter frame and is opposite to the left measuring shaft, the lower portion of the measuring rod is arranged in the transverse long hole in the upper portion of the base body, and the lower end column of the measuring rod is in interference fit to the radial hole of the left measuring shaft.
Compared with the prior art, the invention has the remarkable advantages of measuring accuracy, convenience and rapidness in measurement and capability of carrying out measurement on a machine tool.
Drawings
FIG. 1 is a schematic diagram of the structure of the present invention; fig. 2 is a top view of fig. 1.
Detailed Description
In order to solve the above-mentioned defect existing in the prior art, the technical scheme of the invention, as shown in fig. 1-2, there is a transverse hole in the basal body 6 that slides and matches with measuring shaft 7, there is a bush 8 in this transverse hole, said measuring shaft is two measuring shafts of left, right, there are springs 5 between two measuring shafts of this left, connecting plate 3 connects with right measuring shaft through the screw 2, the front, back of outside of this connecting plate has the round pin axle 16, the end of the round pin axle has steel balls 17, the outer end of the left measuring shaft is hemispherical, in order to guarantee the precision of measurement, the plane that the spherical center of the outer end of two steel balls and left measuring shaft of the above-mentioned connecting plate is horizontal, at the same time, fix a locating plate 15 through the screw 14 on the upper surface of basal body, the lower surface of this locating plate 15 is parallel with the plane that the spherical center of the two steel balls and left measuring shaft end is located. The handle 13 is fixed above the right part of the basal body through a screw, so that the operation is convenient. A measuring rod 12 is arranged above the left part of the basal body, and penetrates through a transverse long hole on the basal body to be in interference fit with a vertical hole on the left measuring shaft. The gauge stand 11 is fixed at the left end of the base body, the dial gauge 9 is fixed on the gauge stand, and the measuring head of the dial gauge is opposite to the measuring rod.
The measuring method of the invention firstly makes a pair of gauge members 1 with the same aperture as that of the part hole to be measured, after the dial indicator is zeroed, the measuring tool can be held by hand, and the steel balls and the spherical surfaces on the left measuring shaft and the right measuring shaft are placed in the hole of the measured part, thus the diameter size of the part hole can be measured.
The measuring tool has the advantages of high dimensional accuracy of the aperture measured by the measuring tool, convenience in measurement and high efficiency.
