Embodiment：
A kind of flat thimble jig structure for grinding machine, reference picture 3 and Fig. 4, it includes being used for the electromagnetism for supporting flat thimble 6
Sucker 11, magnechuck 11 are located in the frame 1 of grinding machine；Emery wheel 12 in frame 1 is located at the top of magnechuck 11, for
Flat thimble 6 is ground.
Reference picture 3 and Fig. 4, fixed plate 3 are provided with magnechuck 11, magnechuck 11 is consolidated fixed plate 3 by magnetic force
Live calmly；The side wall of fixed plate 3 is provided with fixed groove 31, for flat thimble 6 insert it is embedding；When flat thimble 6 is inserted embedded in fixed groove 31
When interior, two side walls of the two relative madial walls of fixed groove 31 simultaneously with the flat thickness direction of thimble 6 fit.Fixed plate 3
Thickness be less than the flat width dimensions of thimble 6, flat thimble 6 is higher than fixed plate 3, so that emery wheel 12 can be to the flat width of thimble 6
The side wall in direction is ground.
Reference picture 3 and Fig. 4, fix length direction of the length direction perpendicular to fixed plate 3 of groove 31；In fixed fixed plate
When 3, keep the length direction of fixed plate 3 consistent with the length direction of magnechuck 11, so that emery wheel 12 is to the flat thickness side of thimble 6
To vertical stress, prevent flat thimble 6 from fixing the length direction of groove 31 in the fixed interior edge of groove 31 and producing movement.
Reference picture 3 and Fig. 4, the quantity of fixed groove 31 is several, all fixes groove 31 along the length direction of fixed plate 3
Set gradually；More flat thimble 6 can be fixed in fixed plate 3 simultaneously, emery wheel 12 is ground to more flat thimble 6 simultaneously,
Improve grinding efficiency.
Reference picture 5 and Fig. 6, spigot surface 32 is provided between the lateral wall of fixed plate 3 and the fixed madial wall of groove 31；When flat top
When in the fixed groove 31 of the insertion of pin 6, spigot surface 32 is oriented to flat thimble 6, in order to which flat thimble 6 inserts fixed groove 31
It is interior；Spigot surface 32 is in circular arc type, to weaken the scratch to flat thimble 6.
Reference picture 5 and Fig. 6, fixed 31 one of madial wall of groove are provided with mounting groove 33, the flat top of the interior edge of mounting groove 33
The sliding of the thickness direction of pin 6, which is provided with, abuts block 4, abuts and is connected with a spring, spring conduct between block 4 and the madial wall of mounting groove 33
Elastic component 5；Spring, to promote abutting block 4 to slide, is offseted with flat thimble 6 so as to abut block 4, further improved to flat by elastic force
The fixed effect of thimble 6.
Abutting block 4 and the sidewall edge that flat thimble 6 offsets is provided with anti-scratch face 41, anti-scratch face 41 is in circular arc type, with
Avoid the lateral wall of the flat thimble 6 of scratch.Because anti-scratch face 41 is in circular arc type, when flat thimble 6 is fashionable to the fixed interpolation of groove 31,
Flat thimble 6 offsets with anti-scratch face, is pushed into so as to abut block 4 automatically in mounting groove 33.
The lateral wall of fixed plate 3 is provided with resigning groove 34, and resigning groove 34 communicates with mounting groove 33；The inner side of resigning groove 34
Wall is welded with plugging plate 341, to block resigning groove 34；When needing to install spring, spring is put into peace by resigning groove 34
In tankage 33；And the both ends of spring are respectively welded on the madial wall of mounting groove 33 and abutted on block 4；Finally by plugging plate 341
It is welded on the madial wall of resigning groove 34, is entered with reducing iron filings in mounting groove 33.Outside the lateral wall of plugging plate 341 and fixed plate 3
Side wall is flush, when flat thimble 6 offsets with plugging plate 341, to prevent the flat thimble 6 of the scratch of plugging plate 341.
Operation principle is as follows：
When needing to be ground a side wall of the flat width of thimble 6, fixed plate 3 is placed on electromagnetism first and inhaled
On disk 11, and flat thimble 6 is inserted in fixed groove 31 one by one；Then move fixed plate 3, make the length direction of fixed plate 3 with
The length direction of magnechuck 11 is consistent.Start magnechuck 11, magnechuck 11 adsorbs flat thimble 6 and fixed plate 3 simultaneously.
Now start emery wheel 12, emery wheel 12 is ground to flat thimble 6 whole in fixed plate 3；Due to the flat thickness of thimble 6
Two side walls in direction are bonded two relative madial walls of fixed groove 31 simultaneously, therefore flat thimble 6 is relatively fixed with fixed plate 3,
Even if fixed plate 3 is slided, flat thimble 6 also will not be crooked, improves the grinding accuracy of the flat width side wall of thimble 6.
Then another side wall of the flat width of thimble 6 is ground in aforementioned manners, so as to ensure cutting for flat thimble 6
Face is rectangular, effectively improves the machining accuracy of flat thimble 6.
