Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Embodiment 1
As shown in Figure 1, a kind of plunger grinding clamp, becomes I-shaped shape, comprises the sheet base plate 2 and top board 4 that be arranged in parallel, and the column connecting portion 6 of connecting bottom board 2 and top board 4, top board 4 is provided with 6-12 accommodating hole 8 of circumference distribution or 6-12 storage tank of circumference distribution.
Concrete, top board 4 and base plate 2 are respectively circular, and top board 4 diameter and base plate 2 equal diameters, connecting portion 6 diameter is the 1/3-2/5 of top board 4 diameter.Certain base plate 2 diameter also can, slightly larger than top board 4 diameter, make fixture entirety more stable, and such as base plate 2 diameter is 1.1 times of top board 4 diameter.Preferred top board 4 is provided with 6-12 accommodating hole 8,9 optimums of circumference distribution, can increase work efficiency, can ensure Grinding Quality again.
Preferred base plate 2 is also provided with some pits 12 of circumference distribution, the quantity of pit 12 is equal with accommodating hole 8 quantity on top board 4, accommodating hole 8 one_to_one corresponding of pit 12 on the distributing position and top board 4 of base plate 2, the opening diameter of pit 12 equals plunger base 14 diameter.The bottom surface of pit 12 can be plane or arcwall face, coordinates difform plunger base 14 bottom end face.Such as pit 12 can be hemispherical or cylindric.
Connecting portion 6 can be open tubular column, i.e. cannula-like, is convenient to be set on the shaft-like keeper of workbench, and arranges some fixing holes (not shown) and workbench on a base plate 2 and located by screw.Can further on the top plate 4 middle part offer through hole 16, be uniformly distributed three fixing holes 18 around through hole 16, the diameter of through hole 16 is less than connecting portion 6 internal diameter, can be 0.9 times of connecting portion 6 internal diameter.This fixture is set in after on above-mentioned keeper, and keeper top props up top board 4 bottom, and with through hole 16 EDGE CONTACT, keeper and top board 4 are threaded fixing by fixing hole 18 further.
In the present embodiment, accommodating hole 8 diameter equals plunger base 14 diameter, and top board 4 bottom and base plate 2 top spacing are less than plunger base 14 axial length, and top board 4 top and base plate 2 top spacing are greater than plunger base 14 axial length.Direct people's grasped fixture connecting portion 6 or after fixture is fixed on workbench, directly above fixture, plunger base 14 can be inserted accommodating hole 8 down, bottom 14 is positioned in pit 12, carries out attrition process subsequently.
Accommodating hole 8 also can be replaced with storage tank by the top board 4 of the present embodiment, and the storage tank degree of depth at least equals plunger base 14 axial length, and without the need to arranging pit 12 on base plate 2, plunger is directly plugged in storage tank.
Embodiment 2
As in Figure 2-4, a kind of plunger grinding clamp, is with the difference of embodiment 1:
Accommodating hole 8 diameter is greater than plunger head 22 diameter, and is less than plunger base 14 diameter.
Base plate 2 comprises substrate 28, the groove being located at substrate 28 upper surface and the connecting plate 32 be embedded in a groove, and connecting plate 32 and connecting portion 6 one, connecting plate 32 and substrate 28 screw thread removably connect.
Preferred fixture also comprises the snap ring 24 that can be contained in accommodating hole 8, snap ring 24 circumferential sides is provided with breach 26, is circumferentially with external screw thread, and the external diameter of snap ring 24 equals accommodating hole 8 internal diameter, internal diameter is more than or equal to plunger neck 34 diameter, is provided with the internal thread matched with snap ring 24 external screw thread in accommodating hole 8.
Now, connecting plate 32 need be separated with substrate 28, below top board 4, plunger head 22 is upwards inserted accommodating hole 8, during insertion, snap ring 24 is snapped in plunger neck 34 by breach 26, together insert accommodating hole 8, simultaneously by snap ring 24 by screw thread precession accommodating hole 8, non-movable piston neck 34 prevents radial direction from rocking.Subsequently connecting plate 32 is embedded substrate 28, plunger base 14 is located and pit 12, and namely screw thread fixed connecting plate 32 and substrate 28 complete the installation of plunger.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to right.
