In 0.005mm, the positioning table may be configured as 0.5～6mm relative to the height of workpiece placed side, and the positioning table is put with workpiece
The perpendicularity for putting face ensures that the logical cave tolerance is bilateral+0.02～0.04mm, leads to cave upper surface and workpiece less than 0.01mm
Placed side distance is 8～12mm, and it is moderate to the magneticaction of workpiece that this distance can be effectively ensured strong magnets 2, the logical cave
Ensure 5～10mm with the both sides of conversion work platform 1 and bottom surface wall thickness, this distance not only proof strength can again ensure that magneticaction was suitable
In, the strong magnets 2 ensure peripheral dimension -0.02～0.04mm；Clamp connecting plate 5 is made up of Cr12mov materials, and quenching is hard
Spend for HRC52～58 degree, the top surface of clamp connecting plate 5 and bottom surface are equipped face, and needs are ground to and just can be carried out less than after Ra0.4
Connection, it is ensured that positioning precision.
The chuck 3, blind rivet 8 and benchmark fixture 4 composition chucking appliance system, the chucking appliance system requires that repetitive positioning accuracy is less than
0.002mm。
The principle of fine positioning magnetic conversion work platform is：Strong magnets 2 are placed into the logical cave arranged on conversion work platform 1
In, the workpiece placed side arranged on conversion work platform 1 in the presence of the magnetic force of strong magnets 2 produces magnetic, it would be desirable to polish
Workpiece 9 be mounted on conversion work platform 1 arrange positioning table side, workpiece 9 is adjusted to into drawing coordinate position and is located
On conversion work platform 1, take out conversion work platform 1 and workpiece 9 after strong magnets 2 and lose magnetism, by chuck 3 and benchmark fixture 4
Assemble, in process workpiece 9 will not cause secondary discharge because of the effect of magnetic force absorption electric discharge impurity, when workpiece 9 is processed
After the completion of directly workpiece 9, conversion work platform 1 and chuck 3 can be detected as integral demounting, such as need secondary operations direct
Work is added on benchmark fixture 4 using workpiece 9, conversion work platform 1 and chuck 3 as integral installation, it is to avoid 9 two centering cores of workpiece
To zero.
The beneficial effects of the utility model are：The height of the conversion work platform 1 in fine positioning magnetic conversion work platform can be with
According to the different height of the different selections of height of workpiece 9, solution cannot realize close electric spark shaping mill Z on routine work platform
Problem present in the processing of the precision workpiece of value stroke, using workpiece 9, conversion work platform 1 and chuck 3 as a whole detection
Avoid the secondary centering of workpiece 9 from checking zero with additional work and ensure that machining accuracy and the precision of workpiece 9, the workbench each group
Part low cost and the manufacturing cost, the simple and convenient operation of workbench assembling of reducing easy to process reduce the workload of operator
Improve production efficiency.
