302 the second groove 422.Further, clamping piece 310 includes the first clamp 316 and is mutually perpendicular to the first clamp 316 or closely
Like the second vertical clamp 318, the first clamp 316 connect with the second mounting portion 216 and is horizontally arranged at interval with connector 120,
Second clamp 318 is equipped with clamping section 302, thus can be staggered with the workpiece that need to be polished, and avoids interfering in bruting process.
As shown in Figures 1 to 3, in the present embodiment, which further includes antitorque component 400, antitorque component 400
Including the extension spring 410 being arranged with 210 longitudinal gap of guide rod and adjusting screw rod 420, one end of extension spring 410 and clamping piece
310 are fixedly connected, the other end is fixedly connected with adjusting screw rod 420, and adjusting screw rod 420 is set on connector 120, connector
120 are equipped with the third connecting hole 126 matched with adjusting screw rod 420；Thus by adjusting the elastic force of extension spring 410,
The torque that fixture self weight generates is compensated, while keeping frictional force when moving between guide rod 210 and linear ball bearing 124 small, no
It will appear stuck phenomenon (while reducing the mutual abrasion between guide rod 210 and linear ball bearing 124), and then make grinding wheel float
It polishes smooth, guarantees stability when polishing.Elasticity of the coefficient of elasticity of the extension spring 410 less than the first compressed spring 230
The coefficient of elasticity of coefficient and the second compressed spring 240, it is preferred that the drawing force of extension spring 410 is less than the first compressed spring 230
And second compressed spring 240 pretightning force.
As shown in figure 4, a kind of polishing process of the present invention, applied to above-mentioned floating workpiece polishing mechanism, including it is as follows
Step:
The pre-pressing force of first compressed spring and the second compressed spring is set according to the material of workpiece and polishing surplus；
The floating workpiece polishing mechanism is mounted on the operating head or manipulator of robot by interconnecting piece and is installed and is beaten
Grinder tool, makes the bistrique for stating the milling tools contact the normal pressure direction generated and the first compressed spring with the workpiece surface
Impact direction and second compressed spring Impact direction is parallel or less parallel；
The workpiece is detached from the milling tools, and first compressed spring and second compressed spring automatically return to initially
Position.
The floating workpiece polishing mechanism is mounted on the operating head or manipulator of robot by interconnecting piece and installs polishing
Tool makes the bistrique for stating the milling tools contact the normal pressure direction and the first compressed spring generated with the workpiece surface
The Impact direction and Impact direction of second compressed spring is parallel or less parallel, and then it is avoided that milling tools and workpiece
Between rigid collision, and motion profile is generated by teaching or off-line editing, realizes Flexible Manufacture, improve polishing workpiece at
Product rate.
In this implementation, the precompressed of the first compressed spring and the second compressed spring is set according to the material of workpiece and polishing surplus
It further include the stroke for adjusting extension spring when clamp force；And then it can compensate for offsetting mechanism self gravity to guide rod and straight-line ball
The torque of bearing keeps guide rod movement more steady, reduces and wear between guide rod and the first mounting portion because of the radial force of generation.
The coefficient of elasticity of the extension spring is less than the coefficient of elasticity of the first compressed spring and the coefficient of elasticity of the second compressed spring, preferably
, the drawing force of extension spring is less than the first compressed spring and the pretightning force of the second compressed spring.
In preferred embodiment:
S1, the first pressure that unlike material, different geometric parameter are selected according to different workpiece materials, different polishing surpluses
The pretightning force of contracting spring and the second compressed spring, the harder needs of the material of workpiece is bigger, the bigger needs of polishing surplus of workpiece
Pretightning force is bigger；
S2, first compressed spring and second compressed spring are pre-compressed and are mounted in floatation element；
Torsion of the mechanism self gravity to guide rod and linear ball bearing is offset in S3, the drawing force for adjusting extension spring, compensation
Square；
S4, operating head or the free end that floating workpiece polishing mechanism is mounted on to robot by the interconnecting piece of installation part are generated
During motion profile, the bistrique of the milling tools is made to contact the normal pressure direction generated and the first pressure with the workpiece surface
The Impact direction of the contracting spring and Impact direction of second compressed spring is parallel or less parallel, is milling tools and workpiece
Between elastic contact pressure is provided, amount of spring compression is bigger, and contact pressure is bigger；
S5 simultaneously generates motion profile by teaching or off-line editing, carries out Flexible Manufacture, when workpiece is detached from milling tools
Afterwards, first compressed spring and second compressed spring automatically return to origin-location under the effect of initial precompression.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
