Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
Primary structure of the present utility model is comprised of the two large divisions: the accompanying drawing 1 of instructions, the B1 in the accompanying drawing 2 are that digital display meter and B2 grating scale are existing mature technologies, these two parts are linked to each other (omitting among the figure) by data line, and grating scale B2 wins 1 and be connected with platform 4 among the A by screw 2 in succession by two grating scales.The A measuring mechanism is principal character of the present utility model, its special character is that it is to support basic platform 4 by the supporting leg 3 among Fig. 3, bearing shaft the first bearing 7 and the second bearing 13 are housed on the platform 4, these two seat supports two axis of guides 5, two axis of guides 5 are equipped with in the linear bearing 28(accompanying drawing 5), linear bearing 28 is contained in the slide 6, and the upper plane of C1 of the upper plane of the C2 of this slide and the second bearing 13 is contour, so just forms a contour reference plane.The second bearing 13 is fixed on the platform 4 and belongs to fixture, slide 6 can be done rectilinear motion along the axis of guide 5, the second bearing 13 is equipped with respectively datum plate 12 and measurement plate 11 with slide 6 and surveys in the post 23(accompanying drawing 4), like this can be similar with slide calliper rule, but such as the stiff end with the part analogy slide calliper rule of the second bearing more than 13, but with the vernier part of slide part analogy slide calliper rule more than 6, the B1 digital display meter is the sighting target district, obviously so just forms a surveying instrument.The second stop means that is formed by adjusting handle 8, the first stop means that is made of lasso 14 and screw 15 limit the measurement range of slide 6, two risers 9 in accompanying drawing 2 and the accompanying drawing 3,16 and dull and stereotyped 10 are reference for installation plates, there is a benchmark to rely on when being mainly used in changing datum plate 12 and measuring plate 11, is convenient to quick-replaceable.
In order to make dynamometry constant, make measured value stable, the utility model draft force apparatus adopts the weight 21 in the accompanying drawing 4, traction rope 20, traction rope 20 is walked around pulley 17, and links to each other with web member 22 on being fastened on slide 6, and the size of dynamometry depends on the quality of weight 21 fully like this.Pulley 17 is supported by pulley spindle 18 and pulley bracket 19.
Accompanying drawing 6 is Quick Measurement mode views of the present utility model;
Measured workpiece 29 can directly be put between the two survey posts 23 can read the actual value that the measured workpiece race is striden bulb diameter, one week of rotary work piece can record the circularities that race is striden bulb diameter again, this function can make the measurement quality of belt pulley be able to further raising, can directly have influence on the transient equilibrium of belt wheel and the life-span of belt because race is striden the circularities of bulb diameter.When changing product specification, the survey post 23 that only needs to change difformity and size according to design drawing gets final product.Measuring the belt wheel external diameter only needs belt wheel is lain on the plane of datum plate 12, measures plate 11 by two and records the external diameter value, and rotary work piece also can record the circularities of external diameter, sees accompanying drawing 7.
