Abstract
The utility model discloses an easy and movable measuring tool for large-size inner diameter of a workpiece which adopts the technical scheme as follows: a main pole penetrates in the through hole of the center of a transverse pole and then is arranged on a connecting block; a screw hole is arranged vertical to the through hole of the transverse pole; a locating bolt is screwed in the screw hole of the transverse pole; the two ends of the connecting block are hinged with two pieces of measuring poles; the two ends of two pieces of driving poles are respectively hinged on the two ends of the transverse pole and the two pieces of measuring poles. The easy and movable measuring tool for large-size inner diameter of the workpiece is convenient for implementing large-size inner diameter measuring on the workpiece under a heating or normal state, improves the measuring precision, avoids hidden safety troubles and guarantees the subsequent operation of the workpiece.
Description
Technical field
The utility model relates to the simple and easy movable survey instrument of a kind of workpiece large scale internal diameter.
Background technology
Workpiece large scale internal diameter needs accurately to measure its internal diameter data when making and keeping in repair the processing operation, satisfy technological requirement with the assurance internal diameter with being connected of counterpart.As the universal joint of roughing main shaft, this universal joint and main shaft are interference fit joint, when changing, need fully heat universal joint, so that its internal diameter obtains expanding, thus the dismounting of enforcement universal joint.In the face of the workpiece that heats, its surface temperature generally reaches about 400 ℃, close-in measurement exists difficulty and danger, during actual measurement, usually hold a length bar near the workpiece diameter reference measure by the workmen, therefore measuring accuracy is low, has had a strong impact on the dismounting operation of subsequent workpiece internal diameter and counterpart.Also there is certain degree of difficulty in the measurement of workpiece its large scale internal diameter under normal condition simultaneously.
Summary of the invention
Technical problem to be solved in the utility model provides the simple and easy movable survey instrument of a kind of workpiece large scale internal diameter, the convenient large scale inner diameter measurement of workpiece when heating or normal condition of implementing of this instrument, improve measuring accuracy, avoided potential safety hazard, guaranteed the subsequent job of workpiece.
For solving the problems of the technologies described above, the simple and easy movable survey instrument of the utility model workpiece large scale internal diameter comprises mobile jib, cross bar, contiguous block, bolt, two driving stems and two sounding rods, described cross bar and contiguous block parallel interval are provided with, described cross bar center has through hole, described mobile jib is vertical at described contiguous block after penetrating described cross bar through hole, the vertical described cross bar through hole of described cross bar is provided with screw, described bolt is twisted in the screw of described cross bar, described two sounding rod one ends are articulated in the two ends of described contiguous block respectively, one end of described two driving stems is articulated in the two ends of described cross bar respectively, and the other end of described two driving stems is articulated in respectively on described two sounding rods.
Be indication measurement data directly perceived, this survey instrument also comprises protractor, and described protractor comprises pointer and index dial, and described pointer is vertical at the hinged end of sounding rod and contiguous block, described index dial is located at described contiguous block one end, and described pointer is positioned at described index dial surface.
Because the simple and easy movable survey instrument of the utility model workpiece large scale internal diameter has adopted technique scheme, be to be located on the contiguous block after mobile jib penetrates the cross bar central through hole, vertical cross bar through hole has screw, be screwed into bolt in the screw of cross bar, hinged two sounding rods in the two ends of contiguous block, the two ends of two driving stems are articulated in respectively on cross bar two ends and two sounding rods; The convenient large scale inner diameter measurement of workpiece when heating or normal condition of implementing of this instrument improved measuring accuracy, avoided potential safety hazard, guaranteed the subsequent job of workpiece.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the simple and easy movable survey instrument of the utility model workpiece large scale internal diameter.
Embodiment
As shown in Figure 1, the simple and easy movable survey instrument of the utility model workpiece large scale internal diameter comprises mobile jib 1, cross bar 2, contiguous block 3, bolt 6, two driving stems 4 and two sounding rods 5, described cross bar 2 and contiguous block 3 parallel interval settings, described cross bar 2 centers have through hole, described mobile jib 1 is vertical at described contiguous block 3 after penetrating the through hole of described cross bar 2, described cross bar 2 vertical described cross bar 2 through holes are provided with screw, described bolt 6 is twisted in the screw of described cross bar 2, described two sounding rod 5 one ends are articulated in the two ends of described contiguous block 3 respectively, one end of described two driving stems 4 is articulated in the two ends of described cross bar 2 respectively, and the other end of described two driving stems 4 is articulated in respectively on described two sounding rods 5.
Be indication measurement data directly perceived, this survey instrument also comprises protractor, and described protractor comprises pointer 8 and index dial 7, and described pointer 8 is vertical at the hinged end of sounding rod 5 and contiguous block 3, described index dial 7 is located at described contiguous block 3 one ends, and described pointer 8 is positioned at described index dial 7 surfaces.The angle that protractor records sounding rod 5 changes, and can extrapolate measurement data, as establishes the long L of being of sounding rod 5 bars, and it is α that angle changes, then the data D=2cos α * L of Ce Lianging.
This survey instrument is when the measuring workpieces internal diameter, at first unscrew bolt, outside mobile mobile jib, contiguous block drives hinged two sounding rods and driving stem draws in, then this survey instrument is stretched in the endoporus of workpiece, move inward mobile jib, contiguous block drives hinged two sounding rods and driving stem expansion, touch the workpiece inner hole wall until two sounding rod free ends, the position of screwed in place bolt mobile jib this moment on cross bar, come this survey instrument of back rotation, judge whether two sounding rod free ends contact normally with endoporus, to guarantee to measure the most real internal diameter data.The numerical value of measurement can be directly read in the setting of throughput hornwork simultaneously.
After this survey instrument comes into operation,, realize measurement fully flexibly and comfortably, thereby can in time understand the variable quantity of heating back workpiece endoporus its internal diameter in the face of being in when adding the large-scale workpiece of pining for.The data of measuring are reliable, and error is little, can the anticipation workpiece whether reach the requirement of cooperation.And at the workpiece of different inner diameters, can realize simply, measure easily by this survey instrument, the more important thing is the potential safety hazard of having avoided the people to go to contrast internal diameter varies near heated parts.Guarantee security, practicality and reliability in the workpiece diameter measurement, guaranteed carrying out smoothly of workpieces in subsequent operation.
