Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
after the data measurement is finished, the automatic three-coordinate flexible measurement tool clamp b releases parts, the AGV cooperative robot a takes away the workpiece, and the next positioning, clamping and measuring link is waited.
The automatic three-coordinate flexible measurement tool clamp comprises a bottom plate 1, wherein two groups of rod workpiece positioning assemblies and one group of shaft workpiece positioning assemblies are symmetrically arranged on the bottom plate 1 along the center.
The rod-type workpiece positioning assembly comprises a first pressing finger 4 and a first supporting block 7 which are in driving connection through a first rotary clamping cylinder 20, wherein two groups of first measuring tool eccentric columns 11 are arranged on one side of the first pressing finger 4, and one group of measuring tool concentric columns 12 and a second measuring tool eccentric column 15 are arranged on the other side of the first pressing finger 4;
the first measuring tool eccentric column 11 and the second measuring tool eccentric column 15 are both installed on the bottom plate 1 through bolts and nuts, and can rotate around a vertical axis to change the distance between the first supporting block 7 and the measuring tool eccentric column 12.
Further, a first rotary clamping cylinder 20 is mounted to the base plate 1 through a cylinder coupling seat 10.
In order to improve the flexibility of installing the tool clamp, a plurality of bottom plate cushion blocks 14 are arranged at the bottom of the bottom plate 1 to correspondingly adjust the vertical height of the three-coordinate measuring machine c.
In order to realize that the workpiece can not be damaged when the rod-type workpiece is clamped, a compression nylon pad 5 can be arranged at the bottom of the front end of a first compression finger 4, and based on the same design principle, a first nylon stopper 6 can be respectively arranged at the top ends of a measurement tool concentric column 12 and a second measurement tool eccentric column 15, and a fourth nylon stopper 19 can be arranged at the top end of the first measurement tool eccentric column 11.
The two sets of rod-like workpiece positioning assemblies have substantially the same structural design, and are only slightly different in the surface shape of the second support block 8 and the arrangement direction of the second rotary clamping cylinder 21, so that the two sets of rod-like workpiece positioning assemblies simultaneously position and clamp the first swing arm idle rod 23 and the second swing arm idle rod 24 along the centrosymmetric direction.
Taking the example of positioning and clamping the first swing arm idler bar 23,
initially, the first rotary clamping cylinder 20 drives the first pressing finger 4 to swing out, that is, the first pressing finger 4 is located outside the whole rod-like workpiece positioning assembly, so as to leave a sufficient space for placing a workpiece;
firstly, a first swing arm idle rod 23 is placed on a first damping head 6 at the top ends of a first supporting block 7 and a measuring tool concentric column 12 through an AGV cooperative robot a, and the first supporting block 7 and the measuring tool concentric column 12 limit the movement of a workpiece in the Z-axis (vertical) direction and the X-axis (longitudinal) direction;
the distances between the first measuring tool eccentric column 11 and the second measuring tool eccentric column 15 which are screwed on the bottom plate 1 and the first supporting block 7 and the distance between the first measuring tool eccentric column and the second measuring tool eccentric column 12 are changed, and then a fourth damping tap 19 of the first measuring tool eccentric column 11 and a first damping tap 6 of the second measuring tool eccentric column 15 respectively contact and clamp a workpiece from two sides so as to limit the movement of the workpiece on a Y axis (transverse direction);
then, the first rotary clamping cylinder 20 rotates first and then linearly drives the first pressing finger 4 to move, the pressing nylon pad 5 at the bottom of the front end of the first rotary clamping cylinder directly presses on the upper surface of the first swing arm idle rod 23, and only the pressing nylon pad 5 presses down on the upper surface of the first swing arm idle rod 23;
therefore, the positioning assembly for the group of rod type workpieces realizes reliable and stable positioning and clamping on the first swing arm idle rod 23 in the three-axis directions of X, Y and Z axes.
Because the first pressing finger 4 is used for pressing the nylon pad 5 to be smaller in contact surface with the workpiece when clamping the workpiece, the whole measurement size of the work can be exposed, and the purpose that the workpiece can be measured to obtain all data by one-time clamping is achieved.
After the first swing arm idle rod 23 is clamped and positioned, the three-coordinate measuring machine c starts to measure, after the measurement is finished, the first rotary clamping cylinder 20 drives the first pressing finger 4 to loosen the workpiece in a linear and rotary mode, and the measured workpiece is taken away by the AGV cooperative robot a.
The positioning and clamping operations of the other group of rod-like workpiece positioning assemblies in the three-axis directions of the X, Y and Z axes of the second swing arm idle rod 24 are the same, and are not described herein again.
The shaft workpiece positioning assembly is used for positioning and clamping shaft workpieces such as a first non-adjustable supporting rod 25, a second non-adjustable supporting rod 26, a third non-adjustable supporting rod 27 and a fourth non-adjustable supporting rod 28.
The shaft workpiece positioning assembly comprises a second pressing finger 2 and a third pressing finger 3 which are respectively in driving connection with a first rotary clamping cylinder 20 and a second rotary clamping cylinder 21, and two sets of shaft placing connecting blocks 13 and two sets of shaft supporting and adjusting columns 16 which are arranged on a tooling block plate 9.
Wherein, frock bed hedgehopping board 9 passes through screw and bottom plate 1 fixed connection, and the connecting block 13 is placed to the axle type passes through screw and frock bed hedgehopping board 9 fixed connection, and 16 spiro unions of axle type support adjustment column are in frock bed hedgehopping board 9.
Furthermore, a second damping tap 17 and a third damping tap 18 are respectively installed at the top ends of the two sets of shaft support adjusting columns 16.
By applying the shaft workpiece positioning assembly, the shaft placing connecting block 13 is used for placing a workpiece and limiting the movement and rotation of the workpiece along the Z-axis (vertical direction) and the X-axis (longitudinal direction); the shaft support adjusting column 16 provided with a second damping faucet 17 and a third damping faucet 18 at the top end is used for supporting the workpiece and limiting the rotation of the workpiece around the X axis;
the first rotary clamping cylinder 20 and the second rotary clamping cylinder 21 respectively drive the second pressing finger 2 and the third pressing finger 3 to press the upper surface of the workpiece, so that the workpiece is pressed to obtain stable and reliable positioning.
In order to improve the compatibility of the positioning and pressing operations of the workpiece, the shaft-type placing connecting block 13 is provided with a V-shaped profile groove 31 or a rectangular profile groove 32, so that different profile structures can be positioned to prevent the structures from rotating around an X axis or a Y axis.
As above, the embodiments given in connection with the drawings are only preferred for achieving the objects of the present invention. Those skilled in the art can now appreciate that other alternative configurations consistent with the present invention may be readily devised. Other structural features thus obtained are also intended to be within the scope of the present invention.
