Description
Technical field
The utility model relates to instrument of surveying and mapping verifying attachment field; Lens barrel outside diameter measurement mechanism before total powerstation specifically.
Background technology
Front lens barrel is a strength member on total powerstation, and its function is the light path part in total powerstation, and the degree of accuracy of front lens barrel outside diameter has determined spirit-leveling instrument center focal length image quality.Because front lens barrel cylindrical is larger and wall thickness is less (1.5mm), right alignment 0.02, cannot measure accurately and easily cause deformation of mirror cylinder with general measurer (as milscale), therefore need a kind of special measurement device.
Utility model content
The purpose of this utility model is to solve the test problems of the important accuracy requirement of part.
For realizing above object, the technical solution adopted in the utility model is:
Thin-walled cylindrical workpiece excircle measuring device, is characterized in that: by base; Dial framework; Dial gauge; Table block is formed; Wherein take base as matrix, and dial framework is vertically contained in the center of base one end, and dial gauge is contained in the corresponding aperture of dial framework and tightens up; A set of to table block in addition, for determining dial gauge; Described dial framework is contained on base by holding screw; Described is comprised of 1-10 piece table block.
The utility model has the advantages that: measuring error very little (about 0.01mm), can meet drawing requirement completely.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation front view.Wherein: 1 base; 2 dial frameworks; 3 holding screws; 4 dial gauges; 5 pairs of table blocks.
Fig. 2 is the utility model structural representation vertical view.Wherein: 1 base; 2 dial frameworks; 3 holding screws; 4 dial gauges; 5 pairs of table blocks.
Embodiment:
Referring to accompanying drawing 1, Fig. 2, thin-walled cylindrical workpiece excircle measuring device, by base 1; Dial framework 2; Dial gauge 4; Table block 5 is formed; Wherein take base 1 as matrix, and dial framework 2 is vertically contained in the center of base 1 one end, and dial gauge 4 is contained in the corresponding aperture of dial framework and tightens up; A set of to table block in addition, for determining dial gauge.
Described dial framework 2 is vertically contained in the center of base 1 one end by holding screw 3.
Described is comprised of 1-10 piece table block; Diameter with corresponding different product.
During use, will be placed on base 1 table block 5, and by dial gauge 4, withstand and be adjacent on to table block 5, the reading of dial gauge 4 will be set to zero, and take off table block, then measured piece is placed on base, Dui Hao center, the reading of dial gauge is exactly the actual diameter error numerical value of tested part like this.
