Embodiment
As shown in Figures 1 to 4, a kind of jewellery inlay firmness test device, including supporting table 1, in addition to dynamometer 4,
For clamping the fixture 9 of jewellery, fixed seat 10, support base 11, lifting structure 7 and screw mandrel 8 are finely tuned；Fixture 9 and the phase of fixed seat 10
To being arranged on the table top of supporting table 1, the both ends of screw mandrel 8 are rotatablely connected with fixed seat 10 respectively；Screw mandrel 8 is connected with support base 11, is used
Moved playing surface in control support base along supporting table 1；Fine setting lifting structure 7 is fixedly connected with support base 11, and dynamometer 4 rises with fine setting
The lifting axis connection of structure 7 drops.Screw mandrel 8 can be moved playing surface with the control support base 11 of continuous uniform along supporting table 1, therefore dynamometry
Meter 4 continuously and uniformly can apply active force to jewellery, improve push-pull effort firmness measuring accuracy；Thrust jail can be tested simultaneously
Degree or pulling force fastness；It is simple in construction.
As shown in figure 1, when test jewellery inlay firmness, fixture 9 clamps jewellery, and the end of dynamometer 4 is withstood on jewellery
Mosaic component, screw mandrel 8 controls support base 11 closer or far from fixture 9, when mosaic component and jewellery depart from, records dynamometer
The data of 4 displays, when the data of display are less than preset value, it is unqualified that jewellery inlay firmness, on the contrary qualified.Fine setting lifting knot
Structure 7 can adjust the relative altitude of dynamometer 4 so that the end of dynamometer 4 can correspond to the mosaic component withstood on jewellery.
As shown in figure 1, the table top upper surface of supporting table 1 is further fixed on universal angle plate 6, fixture 9 is fixed with universal angle plate 6 to be connected
Connect.Universal angle plate 6 can the table top of relative support platform 1 rotate, therefore the diverse location that can jewellery be inlayed with firmness is tested.
As shown in Figures 1 to 4, one end of dynamometer 4 is fixed with gauge head holder 12, and the free end of gauge head holder 12 is provided with can
The gauge head 5 of dismounting.One end of screw mandrel 8 is fixed with the handle 3 that control screw mandrel 8 rotates.
As shown in Figures 1 to 4, the both ends of fixed seat 10 are further fixed on the slide bar 2 parallel with screw mandrel 8, the support base 11
It is flexibly connected with slide bar 2, handle 3 controls support base 11 to be moved playing surface along supporting table by screw mandrel 8.
As shown in Figures 1 to 4, it is that the noble metal bracket of noble metal set jewelry is delayed that jewellery, which inlay firmness test device,
Slow at the uniform velocity to apply pulling force, whether test noble metal bracket separates with jewels and jade, and it is push-and-pull that value of thrust is recorded when separating
Power firmness F, unit N.
The utility model is exemplified by inlaying the jewels and jade of round bur type, as shown in Figure 1 to Figure 3.From the contact of jewelry girdle
Point A to jewelry girdle planar central B lines be girdle radius, now, the direction of pull and girdle of the gauge head 5 of the end of dynamometer 4
Diameter C is parallel.By test, edge pawl is pulled along direction of pull in stress point G, whether observation pawl separates with contact point, and records
Value of thrust is F.
As shown in Figures 1 to 4, tensile test step：
A) confirm that the electronic console of dynamometer 4 is shown as zero；
B) fixture 9 clamps jewellery, adjusts jewellery putting position, determines that tensile test direction is as shown in Figure 2；
C) gauge head 5 of the free end of dynamometer 4 catches on tested metal claw, rotational handle 3 so that dynamometer 4 is slowly at the uniform velocity remote
From fixture 9, the numerical value of the observation display of dynamometer 4；
If d) metal claw separates with jewels and jade contact point, when dynamometer 4 shows that numerical value is less than regulation F values, then the metal
Pawl pulling force firmness is unqualified；If metal claw does not separate with jewels and jade contact point, dynamometer 4 shows that numerical value is more than or equal to rule
Determine F values, then the metal claw and jewels and jade contact point are qualified, rotate universal angle plate 6, and another metal claw is tested with same method
It is whether qualified with jewels and jade contact point.
As shown in Figures 1 to 4, thrust testing procedure：
A) confirm that the electronic console of dynamometer 4 is shown as zero；
B) fixture 9 clamps jewellery, adjusts jewellery putting position, it is ensured that the gauge head 5 of the free end of dynamometer 4 can withstand tested pearl
Gem and jade bottom；
C) gauge head 5 of the free end of dynamometer 4 catches on tested metal claw, rotational handle 3 so that dynamometer 4 slowly at the uniform velocity leans on
Nearly fixture 9, the numerical value that observation dynamometer 4 is shown；
If d) metal claw separates with jewels and jade contact point, when dynamometer 4 shows that numerical value is less than regulation F values, then the metal
Pawl pulling force firmness is unqualified；If metal claw does not separate with jewels and jade contact point, dynamometer 4 shows that numerical value is more than or equal to rule
Determine F values, then the metal claw and jewels and jade contact point are qualified, rotate universal angle plate 6, and another metal claw is tested with same method
It is whether qualified with jewels and jade contact point.
Above is specific embodiment of the present utility model, it is noted that for those skilled in the art
For, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
