The technical problem to be solved in the present invention is to provide fine positioning magnetism conversion work platforms, solve the nothing on routine work platform
Method realizes the processing close to the precision workpiece of electric spark shaping mill Z value stroke, guarantees workpiece size and shape need, to guarantee
The required precision of precision die.
The technical scheme is that：Fine positioning magnetism conversion work platform, structure include：Conversion work platform 1, strong magnetic
Iron 2, collet 3, benchmark fixture 4, clamp connecting plate 5, nut 6, electric spark fibrous gypsum platform 7, blind rivet 8 and workpiece 9；Fine positioning magnetism turns
The platform connection relationship that changes jobs is：Strong magnets 2 are slidably matched with 1 face contact of conversion work platform, collet 3 and 1 face of conversion work platform
Contact is locked by bolt；Benchmark fixture 4 is locked with 5 face contact of clamp connecting plate by bolt, and nut 6 and electric spark are managed
7 clearance fit of Shitai County is connected by hanging platform, and clamp connecting plate 5 is locked with 7 face contact of electric spark fibrous gypsum platform by bolt.
1 peripheral shape of conversion work platform is rectangular, material selection SKD11 or Cr12mov, and quenching hardness guarantees
HRC50-58 degree, lengthwise dimension range are 600~900mm, and width direction size range is 600~900mm, height side
To 20~100mm of size range；Workpiece placed side, bottom surface, positioning table and logical cave are provided on the conversion work platform 1, it is described
Workpiece placed side surface guarantees roughness Ra 0.1 hereinafter, the workpiece placed side should be less than with bottom surface straightness or flatness
0.005mm, the positioning table are set as 0.5~6mm, the positioning table and workpiece placed side relative to the height of workpiece placed side
Verticality guarantee be less than 0.01mm, the logical cave tolerance is bilateral+0.02~0.04mm, leads to cave upper surface and workpiece and places
For identity distance from for 8~12mm, it is moderate to the magneticaction of workpiece that this distance can be effectively ensured strong magnets 2, the logical cave with turn
Change jobs 1 two sides of platform and bottom surface wall thickness guarantees 5~10mm, this distance can not only guarantee magneticaction be moderate again for proof strength, institute
It states strong magnets 2 and guarantees peripheral dimension -0.02~0.04mm；Clamp connecting plate 5 is made of Cr12mov material, and quenching hardness is
HRC52~58 degree, the top and bottom of clamp connecting plate 5 are equipped face, need to be ground to less than the just company of can be carried out after Ra0.4
It connects, guarantees positioning accuracy.
The collet 3, blind rivet 8 and benchmark fixture 4 form chucking appliance system, which requires repetitive positioning accuracy to be less than
0.002mm。
The principle of fine positioning magnetism conversion work platform is：Strong magnets 2 are placed into the logical cave being arranged on conversion work platform 1
In, the workpiece placed side being arranged on conversion work platform 1 under the action of 2 magnetic force of strong magnets generates magnetism, will need to finish
Workpiece 9 be mounted on the positioning table side being arranged on conversion work platform 1, workpiece 9 is adjusted to drawing coordinate position and is located
Conversion work platform 1 and workpiece 9 lose magnetism after on conversion work platform 1, taking out strong magnets 2, by collet 3 and benchmark fixture 4
Assembly, workpiece 9 will not adsorb electric discharge impurity because of the effect of magnetic force and cause secondary discharge in process, when workpiece 9 is processed
Directly workpiece 9, conversion work platform 1 and collet 3 can be dismantled as a whole after the completion and detected, it can be direct if you need to secondary operation
Workpiece 9, conversion work platform 1 and collet 3 are mounted on benchmark fixture 4 additional work as a whole, avoid 9 two centering cores of workpiece
To coordinate origin.
The beneficial effects of the invention are as follows：The height of conversion work platform 1 in fine positioning magnetism conversion work platform can basis
The height difference of workpiece 9 chooses different height, and solution is cannot achieve on routine work platform close to electric spark shaping mill Z value row
Workpiece 9, conversion work platform 1 and collet 3 are detected and are chased after as a whole by the problem of processing of the precision workpiece of journey
Processing, which avoids the secondary centering of workpiece 9 from checking coordinate origin, ensure that 9 precision of machining accuracy and workpiece, each component of the workbench at
This it is low and it is easy to process reduce manufacturing cost, the workbench assemble it is simple and convenient operate reduce operator workload raising
Production efficiency.
