In order to keep the following explanation of the utility model embodiment to understand and concise, known function is omitted in the utility model
With the detailed description of known elements.
Shown in Figure 1, the utility model embodiment provides a kind of fixture comprising ontology 1 and multiple clamping pieces 2,
Wherein, the top of ontology 1 has the positioning plane for being used to support object to be clamped, and multiple clamping pieces 2 are surrounded for placing wait be clamped
The space of object；Regulating part 3 is connect with ontology 1 and clamping piece 2 respectively, for driving clamping piece 2 to apply chucking power to object to be clamped,
So that multiple clamping pieces 2 clamp object to be clamped.
The utility model is illustrated so that the object to be clamped is diamond compact as an example in the present embodiment, in use,
Diamond compact is placed in the space that multiple clamping pieces 2 surround, and makes diamond compact against on the positioning plane,
Clamping piece 2 is driven to apply chucking power to diamond compact by regulating part 3, so that multiple clamping pieces 2 be made to clamp the diamond
Composite sheet.The fixture structure is simple, is connected firmly after engaging, has been able to solve in the prior art through adhesive bonding diamond
Composite sheet be easy because temperature increase due to loosens, production efficiency is lower and be easy to cause mirror surface pollute etc. technical problems.It needs to illustrate
, it is somebody's turn to do object to be clamped and is not limited only to diamond compact, that is to say, that and the fixture is not limited only to clamping diamond compact,
Suitable for clamping other structures part.
Further, the ontology 1 is cylinder in the present embodiment, and a bottom surface of ontology 1 forms positioning plane, the clamping piece
2 can be arc.Since ontology 1 is cylinder, then positioning plane is formed by as circle, the shape of clamping piece 2 by its bottom surface
It can mutually agree with the shape of the periphery of the positioning plane, it is multiple can firmly to clamp the diamond being supported in positioning plane
Close piece.Certain ontology 1 is not limited only to cylinder, can also be for example triangular prism shaped, four prism type or other shapes, the clamping piece
2 also do not see arc, can also be such as linear, L shape or other shapes.
Further, multiple clamping pieces 2 in the present embodiment are around positioning uniform plane distribution, by multiple around positioning plane
Equally distributed clamping piece 2 clamps diamond compact, can make diamond compact stress equalization, and then keep diamond compound
Piece is firmly clamped, and diamond compact is avoided to slip because of discontinuity equalization.For example, being provided with three in the present embodiment
A clamping piece 2, then on the positioning plane central angle at interval of 120 ° of settings, one clamping piece 2.
Further, the clamping piece 2 in the present embodiment includes that the interconnecting piece positioned at 1 side of ontology is put down with positioning is protruded from
The clamping part in face, regulating part 3 are connect with the interconnecting piece, to drive clamping piece 2 to apply to diamond compact by the interconnecting piece
Chucking power.By taking the clamping piece 2 of the cylindrical ontology 1 and arc in the present embodiment as an example, then a part of the clamping piece 2 is located at
The side of ontology 1 forms interconnecting piece, and another part protrudes from positioning plane and forms clamping part, and the clamping piece 2 is to close to ontology 1
The mobile chucking power for being then applied to diamond compact of axis direction becomes larger, axis direction of the clamping piece 2 to the separate ontology 1
Chucking power that is mobile then being applied to diamond compact becomes smaller, until discharging the diamond compact completely.Using the above structure,
The fixture can be made respectively to form part-structure simple, it is easy to process, it is beneficial to improve production efficiency, reduces production cost.
Further, the regulating part 3 is connected to the middle part of clamping piece 2 in the present embodiment, and the regulating part 3 is made to be applied to clamping
The active force of part 2 acts on the middle part of the clamping piece 2, and the clamping piece 2 is indirectly made to act on the effect on diamond compact
Power is balanced, avoids the active force biasing that clamping piece 2 is applied to because of regulating part 3, and it is compound to cause clamping piece 2 that can not clamp diamond
The phenomenon that piece.
Specifically, the regulating part 3 can be bolt, the first radially arranged screw hole can be equipped on the side of ontology 1,
The middle part of clamping piece 2 is equipped with the second screw hole through it, so that the bolt is passed through the second screw hole and is connected in the first screw hole, passes through
The distance that the axle center of the clamping piece 2 away from ontology 1 is adjusted in the bolt is adjusted, so that it is compound to drive the clamping piece 2 to clamp diamond
Piece discharges the diamond compact.Certainly, which is not limited only to bolt, can also be other structures, as long as being capable of band
Dynamic clamping piece 2 applies chucking power to object to be clamped.
Cooperate Fig. 1, Fig. 2 shown in, the utility model additionally provides a kind of pressing device comprising body 4 and as described above
Fixture 9, body 4 be equipped with retractable top pressure device and the installation pedestal 8 opposite with retractable top pressure device, fixture 9 install
In installation pedestal 8, so that retractable top pressure device can press object to be clamped and be bonded it with positioning plane.
When installing such as diamond compact waiting clamping object on fixture 9, to keep diamond compact close
The fixture 9 on the positioning plane, can be mounted in the installation pedestal 8 of the pressing device, be pressed by the retractable top by fitting
Top set pressure diamond compact fits closely it with positioning plane, and then adjusting bolt again keeps the clamping diamond of clamping piece 2 multiple
Piece is closed, so that the diamond compact can be firmly clamped on the fixture 9.
Further, to enable the fixture 9 to be stably mounted in installation pedestal 8, retractable top is avoided to be pressed top set
The fixture 9 slides when pressing diamond compact, is equipped with limited block in the present embodiment on ontology 1, and in installation pedestal 8
Equipped with limiting slot, limited block is connected in limiting slot and can be connected to installation pedestal 8 for what the fixture 9 consolidated when installation
On, it can prevent fixture 9 from sliding by limited block and limiting slot cooperation.The limited block may also be arranged on clamping piece 2, only
It can engage for fixture 9 to be fixed in installation pedestal 8 with limiting slot.
Further, the retractable top pressure device in the present embodiment includes sequentially connected cylinder 6, pneumatic operated valve 7 and gas source
Interface, gas source interface with external air source for connecting, the extension end face fixture 9 of cylinder 6.In use, by gas source interface and example
Such as the gas source piping connection of factory, to control the flexible of cylinder 6, the extension end of cylinder 6 can be pressed on fixture 9 for example
Diamond compact waits clamping object.
As a preferred embodiment, air gauge 5 can be also set between cylinder 6 and pneumatic operated valve 7, in order to which operator can
To check air pressure at any time, and accurately control the press dynamics of cylinder 6.It, can be by pneumatic operated valve 7 by gas for example, in actual use
Pressure is adjusted to 2MPa, so that cylinder 6 can sufficiently compress diamond compact and positioning plane.Herein it should be noted that
The retractable top pressure device can also be the device such as hydraulic stem, electric pushrod.
The fixture and pressing device of the utility model embodiment, structure is simple, and pressing device can make object to be clamped and determine
Bit plane fits closely, and can firmly clamp object to be clamped by the fixture.
