Abstract
The utility model relates to a measurement device of the depth of a bore groove for mechanical products. The measurement device comprises a tool body (1), a dial indicator (3) mounted at the upper end of the tool body (1), and a measurement rod (2) mounted at the lower end of the tool body (1), wherein the lower end face of the tool body (1) is parallel to the lower end face of the measurement rod (2). The measurement device solves the difficult problems in measuring the key size, and can well ensure the quality of a guide part while improving the processing and assembly efficiency of the guide part, thereby providing a strong guarantee for the good operation of an entire oil pump and an air valve mechanism.
Description
Technical field
The utility model relates to a kind of survey instrument that is used for the endoporus groove depth of engineering goods, particularly a kind of survey instrument of endoporus groove depth of the guide that is used for marine diesel oil pump and valve train.
Background technology
In the oil pump and valve train of marine diesel, its strength member oil pump guide and air valve guide are when whole oil pump and valve train work operation, owing to constantly all be in intermittently ballistic motion state, so the quality of the processing of oil pump guide and air valve guide and assembling plays crucial effects to the good maintenance of oil pump and valve train motion state.In the small end endoporus of oil pump guide and air valve guide, upper side edge to ring groove is all quite high to the precision and the form and position tolerance accuracy requirement of the depth dimensions of endoporus bottom, it is critical size, because of the size at this place directly affects the whole motion state of two kinds of guides, therefore the measurement to this place's size just seems very important in processing and assembling process.Yet because this endoporus aperture is less, adopt the internal hole slot degree of depth of standard universal measurer to measure at present, it is extremely difficult to operate, and is easy to generate artificial measuring error, and the production efficiency and the quality assurance of guide part caused very big influence.
Summary of the invention
The purpose of this utility model be to provide a kind of can improve guide part production efficiency, quality assurance be used for process and assembling process detects the measurement mechanism of endoporus groove depth size.
The purpose of this utility model is achieved in that a kind of measurement mechanism of endoporus groove depth, it is characterized in that: this measurement mechanism comprises body of tool, be installed in the dial gauge and the sounding rod that is installed in described body of tool lower end of described body of tool upper end, the lower surface of described body of tool is parallel with the lower surface of described sounding rod.
Big end down cylindrical hole is set in above-mentioned body of tool, the sliding tray of the strip communicate with this macropore is set on the middle wall of described body of tool, the lower surface of described body of tool and this through hole axially perpendicular; This aperture that described body of tool upper end is passed in the measurement end of described dial gauge extend in this macropore, and at the dog screw of radially fixing described dial gauge of the setting on described body of tool top; The top transition fit of described sounding rod and is provided with the straight pin that is threaded with it in this macropore of described body of tool, stretch out outside the described sliding tray outer end of described straight pin; The lower part of described sounding rod is positioned at outside the lower surface of described body of tool, and is provided with the boss of vertical fixing connection with it.
The xsect of above-mentioned boss can be circle or rectangle, the equal rounding of its outer end corner angle.
The measurement mechanism that the utility model provides is when being used for the internal hole slot depth dimensions of engineering goods processing and assembling process and measuring, the little stomidium of tested guide is put in the bottom of the sounding rod that will match with body of tool earlier, the little transverse plane of body of tool lower surface and tested guide is in contact with one another, mobile straight pin, the lower surface of sounding rod is contacted with the baseplane, hole of tested guide, and transfer to zero-bit with the dial gauge reading this moment; Cylindrical pin with external thread then moves up, simultaneously the lower plane of body of tool is done parallel slowly moving under the situation near the little transverse plane of tested guide, the boss upper surface that makes sounding rod is with after the upper side of hole slot in the tested guide contacts, note the numerical value that dial gauge rotates, this numerical value and plane, sounding rod bottom apart from sum, are the value of desired measurement to the boss upper surface.The measurement mechanism that the utility model provides has solved the measurement difficult problem of critical size herein, in the processing and efficiency of assembling that improve the guide part, also well ensured the quality of guide part, for the good operation of whole oil pump and valve train provides strong assurance.
