Description
Technical field
The utility model relates to a kind of thin-walled blind hole cover parts honing fixtures.
Background technique
Thin-walled blind hole cover parts, because outer wall is relatively thin, poor rigidity is difficult to adopt conventional brace and is clamped to it, is adding
Working hour is easy clamping deformation, causes processing error, also easily part of damage or cutter.Currently, honing fixture is not in the prior art
But structure is complicated, manufacturing cost is high, and complicated for operation when clamping workpiece, clamping workpiece is time-consuming, and clamping speed is slow, work
Inefficiency, and by multifactor impacts such as material, pressure sizes, to ultra-thin part times, so there is part pinching deformations to ask
Topic,
A kind of fixture of thin-walled blind-hole parts, including branch are disclosed in the patent document of 207578154 U of Publication No. CN
Support, the chuck body on support frame, chuck body connect on the support frame, and chuck body includes accommodating thin-walled blind hole zero
The accommodation space of part, the circumferential direction set on accommodation space and the bottom positioned at accommodation space are opposite with the compacting portion of thin-walled blind-hole parts
The first clamping section that should be contradicted, the circumferential direction set on accommodation space and the sky with thin-walled blind-hole parts above the first clamping section
Second clamping section of the corresponding conflict of center portion, the first clamping section and compacting portion rigidly contradict, and the second clamping section and hollow part are flexible
It contradicts, to a certain extent which obviate because injuring caused by clamping to workpiece or cutter, but clamping workpiece is enterprising in fixture
When row processing, if the fixture can not provide well there are position deviation between honing knife access site and workpiece
Gap is swung, feed is caused to fail, cutter or workpiece damage are caused when serious, and workpiece installation and disassembly are inconvenient.

Journey is simple, does not need to borrow other dismantling devices, manually removable.
Further, 2 inner circumferential lower part of lock tube, which is formed with to match for the compacting portion with part 100, merges squeezing for clamping compacting portion
Pressure surface is additionally provided with for by the retaining mechanism of compacting portion locking opposite with compressive plane, retaining mechanism to include along lock tube on lock tube 2
2 circumferential half arc through slots 21 being provided with above compacting portion, the vertical through slot 22 extended downwardly by half arc through slot 21,
Thread screw mechanism for the opposite locking of the cell wall of vertical through slot 22 to be bonded.Rotary screw, by 22 liang of vertical through slot
The cell wall of side is close to each other, and the compressive plane of lock tube 2 is then fitted closely with compacting portion at this time, so that 100 fixed clamp of part be existed
Lock tube 2 is medium to be processed.
Fixture further includes guide sleeves 5 set on 2 upper end of lock tube, the limit that is limited from the lower section of lock tube 2 to part 100
Plate 6, the inner circumferential of guide sleeves 5 are formed with tapered guide face, and guide sleeves 5 are removable in such a way that bolt locks to be mounted on lock tube 2
Upper end, the settings of guide sleeves 5 make honing knife enter 100 inner hole of part more smooth convenient for being oriented to honing knife,
Avoid honing knife and 100 upper end of part very stiff and demanding, furthermore the guide sleeves 5 are installed in the upper end of lock tube 2, can be in lock tube 2
Part 100 play the role of upper end limit, avoid part 100 from moving up；Limit plate 6 is rotatably arranged, and is taking out zero
When part 100, rotary spacing plate 6 makes it not be blocked in 100 lower end of part.
To sum up, the thin-walled blind hole cover parts honing fixture of the utility model, by the setting of relocation mechanism so that honing
Cutter, can be when cutter and part axle center have alternate position spike in processing thin-wall sleeve parts, and part can be carried out effectively floating,
To avoid between cutter and part due to position is not overlapped caused by part, tool damage the problem of；The thin-walled of the utility model
Blind hole cover parts honing fixture, structure is compact to design, and rationally part floating effect is good, clamp speeds are fast, fastening safety can
It leans on, and the installing and dismounting of part is very convenient, the working efficiency greatly improved.
The utility model is described in detail above, its object is to allow the personage for being familiar with this field technology can be much of that
It solves the content of the utility model and is implemented, do not limit the protection scope of the present invention, it is all practical according to this
