Description
Technical field
The present invention relates to measurement mechanism technical field, particularly relate to the measurement mechanism of workpiece circular arc centre to end.
Background technology
Participate in as shown in Figure 1, the upper end of workpiece is with circular arc; When needing to measure center of arc to the distance H of workpiece bottom, adopting common survey instrument, there is following shortcoming: 1) because workpiece upper end is that circular arc is difficult to find benchmark to measure, adding the difficulty of measurement; 2) measuring process is comparatively complicated, and measuring error is comparatively large, reduces measuring accuracy.
Summary of the invention
The object of this invention is to provide a kind of raising measuring accuracy, the measurement mechanism of the workpiece circular arc centre to end of simplified measurement process.
Realize technical scheme of the present invention as follows:
The measurement mechanism of workpiece circular arc centre to end, comprises the amount seat be made up of transverse slat and riser; Described riser right-hand member is provided with groove, and riser top is provided with cover plate; Described cover plate is provided with the screw rod run through; Stretch into bottom described screw rod in groove, cover plate is stretched out at top; Screw rod in described conduit is arranged with " V " type locating rack that can move up and down along screw rod; The screw rod surface of revolution in described conduit is provided with external thread, described " V " type locating rack and screw rod contact position be provided with external thread with the use of internal thread.
Described " V " type locating rack front end and rear end are equipped with baffle plate.By baffle plate, the forward and backward position of " V " type locating rack is fixed, make it more firmly on the amount of being fixed on seat, and prevent it from forward and backwardly to rock.
Screw rod above described cover plate is arranged with rotating scale sleeve, this rotating scale sleeve axle journal is evenly equipped with scale mark.Be convenient to utilize scale to finely tune " V " type locating rack.
Described measurement mechanism also comprises gauge block.For proofreading clock gauge.
The invention has the beneficial effects as follows: because screw rod adopts with " V " type locating rack the mode be threaded, the height of convenient fine setting " V " type locating rack; By " V " type locating rack moved up and down along screw rod, the arc tips of part is blocked, conveniently carries out relative measurement, make measuring process easy, and adopt clock gauge relative measurement measuring accuracy high.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is the first embodiment structural representation of the present invention;
Fig. 2 is the first embodiment of the present invention structure B-B cut-open view;
Fig. 3 is that the first embodiment of the present invention C is to schematic diagram;
Fig. 4 is design of part schematic diagram of the present invention;
Fig. 5 is the second embodiment structural representation of the present invention;
In accompanying drawing, 1 is transverse slat, and 2 is riser, and 3 is amount seat, and 4 is groove, and 5 is cover plate, and 6 is screw rod, and 7 is " V " type locating rack, and 8 is baffle plate, and 9 is rotating scale sleeve, and 10 is iron block, and 11 is part, and 12 is gauge block, and 13 is annular knurl handwheel.
Embodiment
Shown in Fig. 1-Fig. 3, the measurement mechanism of workpiece circular arc centre to end, comprise the amount seat 3 of " L " type be made up of transverse slat 1 and riser 2, described riser right-hand member is provided with groove 4; Described riser top is provided with cover plate 5; Described cover plate 5 is provided with the screw rod 6 its (cover plate) run through; Stretch into bottom described screw rod in groove, top is stretched out cover plate and is arranged with annular knurl handwheel 13; Screw rod in described conduit is arranged with " V " type locating rack 7 that can move up and down along screw rod; The screw rod surface of revolution in described conduit is provided with external thread, described " V " type locating rack and screw rod contact position be provided with external thread with the use of internal thread.Screw rod above described cover plate is arranged with rotating scale sleeve 9 (microdrum), this rotating scale sleeve axle journal is evenly equipped with scale mark.Described measurement mechanism also comprises gauge block.
Before measurement, use hand rotating screw bolt, drive V by screw rod, nut body " type locating rack moves up and down.Pitch due to screw rod is 0.5mm, and rotating scale sleeve axle journal carves 50 mean lines, so every lattice are 0.01mm, so just can when measuring, the amount of moving up and down of fine setting V-arrangement locating piece, allows two V-arrangement faces contact evenly with the arc surface of tested part, thus improves measuring accuracy.
During measurement, be placed on by workpiece on platform, adjustment V-arrangement locating rack and amount seat, make two V-arrangement faces contact with workpiece circular arc face, and roughly coplanar with axis of workpiece, by light slit, can be observed its contact situation.If contact bad, can fine tuning screw rod, V-arrangement locating rack two sides is contacted with workpiece circular arc evenly, now can think the V-arrangement center co-planar of center of arc and V-arrangement locating rack.
Combined gauges is of a size of L=H+h; In formula, L is the size of gauge block, and H is the distance of workpiece circular arc center to bottom surface, and h is the distance of V-arrangement locating piece center to measuring basis.Finally compare and measure with clock gauge.First proofread clock gauge with gauge block, make its pointer to zero, then measure the measurement datum of V-arrangement locating piece, its reading value had both been the difference of workpiece circular arc center to bottom surface distance.
Due to " V " type locating rack thinner thickness, forward and backwardly can rock during measurement, cause measuring error; Preferably, described " V " type locating rack front end and rear end are equipped with baffle plate 8.By baffle plate, the forward and backward position of " V " type locating rack is fixed, make it more firmly on the amount of being fixed on seat, and prevent it from forward and backwardly to rock.
Because weight is comparatively large on amount seat riser, easily causes crank during measurement and tilt, producing measuring error; Or encountered will topple over by hand in measuring process, need again operator to remeasure; For the problems referred to above, the second embodiment of the present invention, shown in Figure 5; Circular iron block 10 is embedded with bottom described transverse slat; Because transverse slat is embedded with the weight that iron block 10 increases transverse slat, not only ensure that precision during measurement, and also not easily topple in the process of hand collision, prevent the trouble of duplicate measurements process, saved Measuring Time.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
