Embodiment Construction

[0007] The present invention is in order to solve the above-mentioned defect that prior art exists, the technical scheme of the present invention, such as Figure 1-2 As shown, the base body 6 is provided with a transverse hole slidingly matched with the measuring shaft 7. A bushing 8 is provided in the transverse hole. The measuring shafts are left and right measuring shafts. The left and right measuring shafts A spring 5 is arranged between the shafts, and the connecting plate 3 is connected with the right measuring shaft by a screw 2. A pin shaft 16 is respectively provided at the front and rear of the outside of the connecting plate, and a steel ball 17 is provided at the end of the pin shaft, and the left measuring shaft The outer end surface of the base body is a hemispherical surface. In order to ensure the accuracy of the measurement, the plane where the center of the two steel balls of the above connecting plate and the center of the spherical surface of the outer end ...

Abstract

The invention discloses an aperture measurement tool. A measurement gauge comprises measurement shafts, a base body and a measurement rod, wherein the measurement shafts comprise a left measurement shaft and a right measurement shaft which are equipped in transverse holes of the base body in a sliding mode, a spring is arranged between the left measurement shaft and the right measurement shaft, a connection board is connected with an outer end of the right measurement shaft, front and back portions of the connection board are provided with holes in tight matching with pins, outer end heads of the pins are provided with steel balls, an outer end surface of the left measurement shaft is a semi-spherical surface, a right upper surface of the base body is provided with a positioning board, a lower surface of the positioning board is parallel with a plane which front and back steel ball centers on the connection board and a center of the semi-spherical surface at the outer end of the left measurement shaft are on, a right upper surface of the base body is provided with a handle, a gauge frame is fixed on an upper surface of a left end of the base body, a lower portion of the measurement rod is arranged in a transverse long hole at an upper portion of the base body, and a lower end column of the measurement rod is in interference fit with a radial hole of the left measurement shaft.

Description

technical field [0001] The invention relates to a measuring tool, especially an aperture measuring tool. Background technique [0002] When high-precision hole parts are processed on a special machine tool, the size of the part hole needs to be measured several times during the trial processing of the first part until the hole size meets the design requirements, and then the hole diameters of multiple parts are processed in this state After the size is stable, batch processing can be carried out. Due to the high precision of the hole diameter of the parts, the measurement in the first part processing should be measured on the machine tool to avoid errors caused by the clamping of the parts. However, the length of the existing conventional internal diameter measuring gauge is too long and cannot be measured due to the limitation of the space of the machine tool. Special measurement tools need to be designed. Contents of the invention [0003] The purpose of this inventi...
