Detailed description of the invention
Fig. 1 is appearance schematic diagram of the invention;
Fig. 2 is positive structure schematic of the invention;
Fig. 3 is side structure schematic diagram of the invention.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings of the specification.
As shown in Figure 1 to Figure 3, real axis straightness check tool provided by the invention, the bracket 6 including a cuboid frame shape, Bracket 6 has four vertical supporting legs, and the bottom of each supporting leg rotates respectively is equipped with a castor 7 easy to remove, adjacent It is connected with a horizontally disposed square steel between the lower part of two supporting legs, and is welded and fixed by square steel.
Supporting leg is respectively that two front leg struts and two rear support legs, four supporting legs are distributed in the quadrangle of bracket 6 along the longitudinal direction, And front leg strut is 50mm higher than rear support leg, keeps pedestal 5 skewed in the front is high and the back is low, and real axis to be measured rolls automatically when convenient for detection It is dynamic, it is not necessarily to manual rotation, pedestal 5 is welded on the top of bracket 6, and pedestal 5 is by four channel steel head and the tail welding rectangularities, pedestal The bottom on 5 two sides in front and back bears against on the top of foreleg and the top of back leg and is welded and fixed.
There are two slideways 4 along the front-rear direction arranged for interval of pedestal 5, a measurement is respectively disposed with along every slideway 4 Sliding rail 3, the cross section of measurement sliding rail 3 are semicircular arc protruding upward, and measure sliding rail 3 and protrude from the upper surface of slideway 4 simultaneously It is fixedly connected, a crossbeam 1 is provided with right above the left and right directions of pedestal 5, the middle part underhung of crossbeam 1 has a survey Gauge block 2, measuring block 2 arrange that two slideways 4 respectively symmetrically are arranged in the left and right of 2 lower section of measuring block along the front-rear direction of pedestal 5 Two sides make the rolling symmetery of part to be measured, are not in biggish measurement error.
Difference in height between the bottom of measuring block 2 and the top for measuring sliding rail 3 is set in advance as the standard of straightness 0.3mm Whether the diameter of real axis, real axis to be measured can freely roll and can check whether to comply with standard by the difference in height.
It is further preferred that being bolted to connection a fixing sleeve 9 on the downside of the middle part of crossbeam 1, divide on fixing sleeve 9 It does not open up there are three perforative through-hole 8 in left-right direction, each through-hole 8 is uniformly arranged along the front-rear direction of fixing sleeve 9, along fixing sleeve A groove is offered in the middle part of 9 bottom surface, groove is arranged along the longitudinal direction, and the adaptation sliding of measuring block 2 is set in groove, and is surveyed The bottom of gauge block 2 protrudes from groove, and measuring block 2 is equipped with the mounting hole being adapted to through-hole 8, and mounting hole can be logical with any one Hole 8 is fixedly connected to adjust the position of measuring block 2, to adapt to different operating condition and part size.
The material of crossbeam 1, slideway 4 and pedestal 5 is channel steel, and channel steel upper and lower surface is the plane to polish flat.The material of supporting leg Matter is square steel, the specification of channel steel are as follows: C10,6M, the specification of square steel are as follows: 50 × 50,10M.Measurement sliding rail 3 heat treatment hardness be Then HRC48-52 is ground, be fixed on slideway 4 finally by being bolted.
In the use of the present invention, the difference in height of measuring block 2 and measurement sliding rail 3 is diameter+straightness of standard real axis 10 (21.8+0.3=22.1mm), as soon as surface is such as passed through when real axis to be measured rolling circumferential distance on measuring sliding rail 3 Straightness is qualified, complies with standard the identical requirement of real axis 10, otherwise blocks motionless straightness with regard to overproof, test failure, in this way The cost and trouble for opening up central axis are eliminated significantly, saves process, can not only be realized quickly sorting detection straightness, may be used also To avoid occurring the overproof problem of centre bore concentricity in the past.
The present invention, structure is simple, swift to operate, saves the process and cost of both ends aperture, and it is straight quickly to sort detection Dimension, and the problem for avoiding centre bore concentricity overproof.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn that the knots made under the inspiration of the present invention Structure variation, the technical schemes that are same or similar to the present invention are fallen within the scope of protection of the present invention.
