Embodiment

See also Fig. 1 to Fig. 4, person shown in the figure is the structure of the selected embodiment of the utility model, and this only uses for explanation, is not subjected to the restriction of this kind structure in patented claim.

Rotating disc type workpiece two dimension machined surface measuring equipment of the present utility model comprises:

One board 1, it generally is a rectangular box, left and right two sides of this board 1 have leader 11 respectively, the top of this board 1 has one by behind the forward direction and the top board 12 of the predetermined angular that is inclined upwardly, be penetrated with a circular containing hole 121 on this top board 12, the apical margin of this containing hole 121 is formed with a large-diameter portion 122.

Two sides of this containing hole 121 have a location screw 13 respectively, this two positioning screw hole 13 is respectively with the fixing supporter 15 of bolt 14, having elongated slot 16 on this two supporter 15 passes for bolt 14, and the end of this two supporter 15 is respectively equipped with the guide wheel 17 of a parallel top board, moreover, the rearward position of this top board 12 is pivoted with a side direction and pushes against member 18, in this example, this side direction pushes against and is provided with a torsionspring 181 between member 18 and the top board 12, and the free ending pivot that this side direction pushes against member 18 is provided with one second guide wheel 19.

One rotating mechanism 2, it has an annular and is fixed in lining 21 in the containing hole 121, these lining 21 apical margins have an articulated section 211 than large diameter, the bottom of this articulated section 211 has splendid true Pingdu, the bottom of this lining 21 is fixed with the positioning disk 22 of a circle, the bottom of this positioning disk 22 then fix one be positioned at board 1 gear motor 23, this gear motor 23 has a rotating shaft 24 that is upward through positioning disk 22,24 of this rotating shafts link unification driving gear 25, and this driving gear 25 is that a scallop 27 that is incorporated into a rotating disk 26 bottoms rotates for driving rotating disk 26, and the top of this rotating disk 26, the bottom surface has the splendid depth of parallelism.

One two-dimentional measurement group 3 has one and supplies to measure the first measurement group 31 and of the dimension that is parallel to rotating disk 26 end faces for the second measurement group 32 of amount perpendicular to the dimension of rotating disk 26 end faces.

This first measurement group 31 has first pole 311 of being located at board 1 top board 12 front sides, this first pole 311 is to extend from bottom to top, and on this first pole 311 in conjunction with first cross bar 312 of a usable rotational direction and high and low position, then articulate on this first cross bar 312 in conjunction with one first scale 313, this first scale 313 is protruding with one first gauge head 314.

This second measurement group 32 has second pole 321 of being located at board 1 top board 12 rear sides, this second pole 321 is to extend from bottom to top, and on this second pole 321 in conjunction with second cross bar 322 of a usable rotational direction and high and low position, then in conjunction with one second scale 323, this second scale 323 is protruding with one second gauge head 324 on this second cross bar 322.

The using method of the utility model measuring equipment is as described below, see also Fig. 4, the workpiece 4 of circle is placed on the rotating disk 26 with its plane, and the position, axle center that makes this workpiece 4 and rotating disk 26 is on same axis, adjust this two supporter 15 again, make this two guide wheel 17 can support two sides of workpiece 4, again this two bolt 6 is screwed, make supporter 15 fixing, and this side direction pushes against elastic force effect meeting that member 18 is subjected to torsionspring 181 and pivots and be butted on workpiece 4 by second guide wheel 19 towards workpiece 4, makes 3 clamp position of this second guide wheel 19 and 4 formation of 17 pairs of workpiece of two guide wheels.

The desire that then first gauge head 314 of first scale 313 of the first measurement group 31 is adjusted to contact workpiece 4 end faces measures the position, and first scale 313 is made zero; The desire that again second gauge head 324 of second scale 323 of the second measurement group 32 is adjusted to contact workpiece 4 peripheries measures the position, and second scale 323 is made zero.

Last start and deceleration motor 23 makes this driving gear 25 drive rotating disk 26 and rotates synchronously, and this moment, this workpiece 4 was also followed rotation.The angle because the top board 12 of this board 1 tilts, and this side direction pushes against member 18 and can be subjected to the elastic force effect of torsionspring 181 and push against workpiece 4 by second guide wheel 19, so, workpiece 4 can move down and be held on by two guide wheels 17 of two supporters 15, and the bottom surface of this workpiece 4 is smooth end faces in rotating disk 26.The more important thing is: the bottom of the articulated section 211 of this lining 21 can be smooth with the bottom surface of rotating disk 26, forms very smooth-going rotation, so can drive workpiece 4 rotations as reference field by the end face with rotating disk 26 and carry out the two dimension measurement.

Therefore, when this workpiece 4 rotates, first gauge head 314 of first scale 313 of the first measurement group 31 can measure on the same circumference of workpiece 4 end faces, so can find out the peak and the extreme lower position of workpiece 4 easily, judges the not parallel direction of bottom surface, workpiece 4 top with this; Moreover when workpiece 4 rotated, second gauge head 324 of second scale 323 of the second measurement group 32 can measure in the periphery of workpiece 4, to measure the eccentric degree of workpiece 4 circumference.Especially carry out at high proportion and during a large amount of QC testing, the user only needs workpiece 4 is put rotating disk 26 one by one, promptly can two dimension measure the parallelism error value and the eccentric error value of structure group 3 measuring workpiece, so just can significantly save the time of QC testing.
