The technical scheme adopted by the utility model is as follows: the product to be tested is placed in the base module, when the product to be tested is used, the product to be tested in the base module is pressed by the lower pressing die bottom group, the lower pressing module comprises a pressing block, a pressing plate and a plurality of pressing head assemblies, the pressing plate is connected with the pressing block through a plurality of connecting pieces, and the pressing head assemblies are all arranged in the pressing plate.

Further, the base module includes support plate, faller, tail faller and bottom plate, the support plate sets up on the faller, the faller with the tail faller is connected, the tail faller with the bottom plate is connected, the product that awaits measuring sets up on the faller.

Further, a plurality of the one end of pressure head subassembly all is connected with the spring, the spring sets up the pressure head subassembly with between the briquetting, the pressure head subassembly float connect in the briquetting.

Furthermore, two groups of waist-shaped holes are symmetrically arranged on the pressing block.

Further, still be provided with spacing post on the briquetting, the one end of spacing post with the clamp plate is connected, the other end of spacing post with the base module is connected.

Further, the base is provided with a plurality of reference columns, and a plurality of reference columns are connected with an external fixing mechanism in a matched mode.

The utility model has the beneficial effects that: the utility model adopts the design of multi-pressure head floating connection, realizes one-to-one accurate pressing of products to be tested, has simple structure, convenient disassembly, is suitable for products with different specifications, has accurate stress point, and reduces the overproof stress caused by the clearance avoidance of the bottom plate; and add spacing post design, set up the biggest pressfitting limit of pushing down the module, avoid the dependent stress of pushing down to surpass the product and bear the scope, lead to the product to damage.

Detailed Description

As shown in fig. 1 to 3, in this embodiment, the present invention includes a base module 1 and a pressing module 2, a product 3 to be tested is placed in the base module 1, when in use, the pressing module 2 presses the product 3 to be tested in the base module 1, the pressing module 2 includes a pressing block 4, a pressing plate 5 and a plurality of pressing head assemblies 6, the pressing plate 5 is connected with the pressing block 4 through a plurality of connecting members 14, the plurality of pressing head assemblies 6 are all disposed in the pressing plate 5, and the plurality of connecting members 14 all use equal-height screws. The design that adopts many pressure heads to float and connect realizes the accurate pressfitting of one-to-one of awaiting measuring product 3, and simple structure dismantles conveniently, is applicable to the product of different specifications.

In this embodiment, the base module 1 includes a carrier plate 7, a needle plate 8, a tail needle plate 9 and a bottom plate 10, the carrier plate 7 is disposed on the needle plate 8, the needle plate 8 is connected with the tail needle plate 9, the tail needle plate 9 is connected with the bottom plate 10, and the product 3 to be tested is disposed on the needle plate 8.

In this embodiment, a plurality of the one end of pressure head subassembly 6 all is connected with the spring, the spring setting is in pressure head subassembly 6 with between the briquetting 4, pressure head subassembly 6 float connect in briquetting 4, pressure head subassembly 6 sticiss the end and be provided with multiple size. The design that adopts many pressure heads to float to connect avoids pressure head subassembly 6 rigidity to push down and leads to the product to damage, and the many sizes pressure head realizes that one-to-one sticiss completely, has better flexibility.

In this embodiment, two sets of kidney-shaped holes are symmetrically disposed on the pressing block 4. The waist-shaped hole is connected with the external linear motion mechanism, so that the working efficiency is improved, and the fatigue strength of workers is reduced.

In this embodiment, the pressing block 4 is further provided with a limiting column 12, one end of the limiting column 12 is connected with the pressing plate 5, and the other end of the limiting column 12 is connected with the base module 1. Adopt spacing post 12 design, set up the biggest pressfitting limit of pushing down module 2, avoid the dependent stress of pushing down to surpass the product and bear the scope, lead to the product to damage.
