Description
Technical field
It the utility model is related to detection technique field, and in particular to a kind of fixture for being used to clamp metallographic inlaying samples.
Background technology
Metallographic sample inlay refer to sample size it is too small or it is in irregular shape cause grinding and polishing difficult, just need to inlay
It is embedding, it can so make sample polishing convenient, improve operating efficiency and the accuracy of experiment.Inlay and be generally divided into cold edge and heat edge two
Kind.In metallographic sample mosaic process, typically metallographic inlaying samples are clamped using antimagnetic type tweezer, but due to metallic phase mounting
Embedding sample is cylindrical, and antimagnetic type tweezer head retaining part is straight, smaller with inlaying samples contact area, easily presss from both sides
Hold unstable situations such as even sample slides.In addition, antimagnetic type tweezer head is more sharp, sample is easily scratched in clamping process makes
Into destruction.
The content of the invention
The technical problems to be solved in the utility model is to overcome problem above existing for prior art, there is provided one kind is used for
The fixture of metallographic inlaying samples is clamped, the clamping sample that can stablize is simple in construction, easy to operate.
In order to solve the above technical problems, reaching above-mentioned technique effect, the utility model is achieved through the following technical solutions：
A kind of fixture for being used to clamp metallographic inlaying samples, including two clamping parts being oppositely arranged, two clampings
The one end in portion is connected by elastic joint part, and two clamping parts and elastic joint part cooperatively form U-shape structure, and the elasticity is even
Socket part is arcuate structure, and the other end of the clamping part has V-type clamping plate, and V-type groove is provided with the middle part of the V-type clamping plate.
Further, the radius of curvature of the elastic joint part is 5-10mm.
Further, hand-held cover is provided with two clamping parts, is provided between the hand-held cover and clamping part
Spring relief portion, one end of two hand-held covers are connected with rotating shaft assembly, the rotating shaft assembly and elastic joint part
Connection.
Further, the spring relief portion includes lead, and limiting plate, the lead are provided with the lead
One end is connected through clamping part with lock screw, and the limiting plate abuts with clamping part, and the lead other end passes through hand-held
Cover is connected with stop nut, and stage clip is arranged with the lead between the limiting plate and hand-held cover.
Further, avoid holes are provided with the hand-held cover, the lead is set through avoid holes, the lead
Diameter, which is less than, avoids bore dia, and the avoidance bore dia is less than stop nut diameter.
The beneficial effects of the utility model are:
The elastic joint part of arcuate structure can bend or bend outwards inwardly so that clamping diameter range is bigger, increases
Contact area is added, simple to operate, design V-type clamping plate is inlayed for clamping the metallographic of diameter within the specific limits in end
Sample, contact area is added, sample can be avoided to come off and destroy, particularly the V-type groove on its surface, it is possible to increase clamping connects
Contacting surface is accumulated, and improves clamping dynamics.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.Specific embodiment of the present utility model is shown in detail by following examples and its accompanying drawing.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding to of the present utility model, forms the part of the application,
Schematic description and description of the present utility model is used to explain the utility model, does not form to of the present utility model improper
Limit.In the accompanying drawings：
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the structural representation of another embodiment of the utility model；
Fig. 3 is part-structure enlarged diagram in the utility model Fig. 2.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
Shown in reference picture 1, a kind of fixture for being used to clamp metallographic inlaying samples, including two clamping parts 1 being oppositely arranged,
The one end of two clamping parts is connected by elastic joint part 2, and two clamping parts and elastic joint part cooperatively form U-shape structure,
The U-shape structure can be horn-like opening, and elastic joint part is arcuate structure, it is possibility to have the structure of coiling is formed, clamping
The other end in portion has V-type clamping plate 3, and V-type groove 4 is provided with the middle part of V-type clamping plate.When clamping sample, when nature lower clamp
When clamp structure opening size is more than sample diameter, fixture is entangled into sample, extruded by the elastic joint part of fixture to clamp
Sample, hold two clamping parts and clamping can be achieved.Size, which is opened, when nature lower clamp clamp structure is less than sample diameter
When, need first to open clamp structure, untill it can entangle sample, clamped after entangling by the elastic joint part return of fixture
Sample.Breadth Maximum is 50mm to above-mentioned fixture in its natural state, can directly clamp φ 30mm metallographic inlaying samples, therefore this folder
Tool can clamp the common specification of existing metallographic inlaying samples：φ 25mm, φ 30mm, φ 40mm etc..
The radius of curvature of above-mentioned elastic joint part is 5-10mm, is easy to have good elasticity, is also convenient for holding.
In clamping, particularly cylindric inlaying samples of metallographic, have and clamp the problems such as unstable, using can after this fixture
Stable clamping.
In another embodiment, as shown in Figures 2 and 3, hand-held cover 5 is provided with two clamping parts, holds cover and folder
Hold and spring relief portion 6 is provided between portion, one end of two hand-held covers are connected with rotating shaft assembly 7, rotating shaft assembly and bullet
Property connecting portion connection.Hand-held cover can provide more comfortable holding effect, and rotating shaft assembly can ensure two hands
Cover is held to fix and axle turnable, wherein spring relief portion can play good supporting role between hand-held cover and clamping part, when
