Abstract
The utility model relates to holding forceps, belongs to the technical field of holding tools, and particularly discloses a pair of metallographic specimen grinding and polishing holding forceps, which mainly comprises a handheld main body round pipe, a balancing air bubble, and a holding mouth, wherein the handheld main body round pipe is positioned in the middle, the balancing air bubble is connected to the upper end of the handheld main body round pipe, and the lower end of the handheld main body round pipe is connected with the holding mouth. The holding mouth and the handheld main body round pipe adopt a one-piece concentric round pipe, an elastic circular arc-shaped steel plate for pressing the metallographic specimen is arranged on the inner side of the housing mouth, the upper end of the elastic circular arc-shaped steel plate is fixed on the inner wall of the handheld main body round pipe, the lower end of the elastic circular arc-shaped steel plate is clung to a threaded hole at the holding mouth and is in the same length as the holding mouth, and a tightening screw is arranged at the threaded hole. The holding forceps can enable an experimenter to grind and polish metallographic specimens conveniently, easily and safely, can guarantee the smoothness on the grinding and polishing surface of the metallographic specimens and improve the processing precision, and is simple in structure, low in cost, and simple in operation.
Description
Technical field
The utility model relates to a kind of gripper clamp, and especially a kind of metallographic specimen grinding and polishing gripper clamp belongs to the clamping device technical field.
Background technology
At present when manufacturing metal material to controllable quality and research, perhaps during the experiment of university's metal material subject, all need carry out metallographic examination, therefore usually need prepare the metallographic specimen sample that can be used for the microscopic observation check.Mainly include steps such as corase grind, fine grinding, metallurgical polishing in the preparation process of metallographic specimen; And all lean on experimenter's manual operations in these a few step operations; The experimenter need pinch operations such as metallographic specimen is polished repeatedly, polishing with finger, yet because the metallographic specimen individuality is smaller, experimenter's finger tends to very tired; Be affectedly bashful shakiness; One gives the preparation of metallographic specimen because of the action of finger easily brings deviation, is difficult to guarantee the smooth of metallographic specimen surface, and two come also very likely to make finger to be frayed by metallographic specimen grinding and polishing machine.
Therefore, can design the special-purpose clamping device of a kind of metallographic specimen grinding and polishing to overcome above-mentioned defective, for those skilled in the art have opened up brand-new thinking.
The utility model content
The utility model aims to provide and a kind ofly can grasp the metallographic specimen grinding and polishing gripper clamp that metallographic specimen is polished, polished; Both can guarantee the smooth of metallographic specimen grinding and polishing surface, and can make the experimenter when polishing, polishing metallographic specimen, avoid the tired or damage of pointing again.Its technical scheme that adopts is following:
This metallographic specimen grinding and polishing gripper clamp mainly comprises hand-held main body pipe, balance bubble and jaw; Wherein, said hand-held main body pipe mediates, and its upper end connects said balance bubble; The lower end connects said jaw; Said hand-held main body pipe and jaw are the concentric pipe of an one, and the inboard of said jaw has elasticity circular arc steel disc, and said elasticity circular arc steel disc upper end is fixed on the inwall of said hand-held main body pipe; Screw hole place on the said jaw and long together with the jaw end is close in the lower end, has parbuckle screw on the screw hole.
Preferably, said parbuckle screw is a flat head screw.
Preferably, the horizontal equilibrium setting that said balance bubble is liquid and bubble is comprising balance bubble liquid and balance bubble air.
Preferably, the inboard of said jaw is provided with circular arc rubber inwall, and is provided with jaw inwall frosted layer.
Compared with prior art, the utlity model has following advantage:
Can make the experimenter convenient, easily, safely metallographic specimen is polished, polished, guarantee the smooth of metallographic specimen polishing, polished surface, improve machining precision; And it is simple in structure; With low cost, simple to operate, can be equipped in application places such as laboratory in a large number.

Embodiment
Below in conjunction with accompanying drawing and instance the utility model is described further:
An embodiment of the utility model is as illustrated in fig. 1 and 2; This metallographic specimen grinding and polishing gripper clamp 1 mainly comprises hand-held main body pipe 2, balance bubble 3 and jaw 4, and hand-held main body pipe 2 mediates, and its upper end connects balance bubble 3; The lower end connects jaw 4; Hand-held main body pipe 2 and jaw 4 are the concentric pipe of an one, and the inboard of jaw 4 has the elasticity circular arc steel disc 5 of pressing metallographic specimen, and elasticity circular arc steel disc 5 upper ends are fixed on the inwall of handing main body pipe 2; Screw hole place on the jaw 4 and long together with the jaw end is close in the lower end, has parbuckle screw 6 on the screw hole.
Friction force during for the clamping of increase metallographic specimen, the inboard of jaw 4 is provided with circular arc rubber inwall, and is provided with jaw inwall frosted layer 7.
When the experimenter operates, outward winding the parbuckle screw 6 at jaw 4 places counterclockwise, will inlay good metallographic specimen and be put into jaw 4, make the outer wall applying jaw inwall frosted layer 7 of metallographic specimen, can make metallographic specimen like this is parallel with integral body.Parbuckle screw 6 is screwed clockwise, parbuckle screw 6 withstands the elasticity circular arc steel disc 5 in the jaw inward again, and deformation take place elasticity circular arc steel disc 5, will pressing lives the outer wall of metallographic specimen, so just can vise metallographic specimen fully; The experimenter metallographic specimen is polished, when polishing; Grasp the hand-held main body pipe 2 of metallographic specimen grinding and polishing pincers; Through the angle of adjustment top balance bubble 3, make the metallographic specimen cylinder keep vertical, to guarantee the smooth of metallographic specimen surface with polishing, surface polishing; Through adjustment bubble 3; Make balance bubble air 9 in the middle of, keep whole balance, thereby guarantee the smooth of metallographic specimen grinding and polishing surface, and whole polishing, polishing process can reach the purpose of protection experimenter finger.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes done based on the utility model or modification all belong to the utility model and require the scope protected.
