Utility model content
The purpose of this utility model is for prior art high temperature or tests for a long time the poor technical problem of effect of heat insulation, a kind of water-cooling type high temperature vibration test fixture is provided, by the mode of the external cooling water pipeline of portion within it, undertaken cooling, realize and continue temperature with high efficiency, avoid result of the test to exert an influence.
The technical scheme that realizes the utility model object is as follows:
A water-cooling type high temperature vibration test fixture, comprises and arranges the upper surface of cooling water channel, the lower surface being connected with vibration table surface and the sidewall that connects upper and lower end face; On upper surface and lower surface, be equipped with a plurality of installing holes, the installing hole of upper surface is for installation test part, and the installing hole of lower surface is used for installing shake table; Inside, upper surface arranges many cooling water channels.
On described sidewall, edge is circumferentially evenly provided with the reinforcement of one or more connections upper surface and lower surface.
Described reinforcement and upper surface, lower surface cohesive position are all provided with knuckle, and the diameter of knuckle is for being more than or equal to 10mm, and the quantity of reinforcement is 8.
The thickness of described upper surface and lower surface and the proportionate relationship of Rib Thickness are 6:5:4.
The shape of described upper surface and the shape of testpieces adapt; The shape of lower surface and the shape of shake table adapt.
Middle part, described upper surface and sidewall middle part have circular hole.
The beneficial effects of the utility model are: water cooling high-temperature vibrating test fixture of the present utility model adopts the mode at upper surface internal placement cooling water channel to realize the cooling to frock, avoids result of the test to exert an influence.The external cooling water pipe of cooling water channel of inside, upper surface, can continue by mobile cooling water to take away efficiently the heat that testpieces conducts, and has improved heat exchanger effectiveness; And, due to cooling water channel is built-in, the advantage such as it is simple that the technical solution of the utility model also has pipeline structure, easy to operate.Hot test part is connected with shake table by water-cooled high-temperature vibrating test fixture of the present utility model, can effectively stop the heat transmission of hot test part to shake table in process of the test, guarantees the normal work of shake table.Meet the requirement of high temperature-vibration test completely.On the upper surface and basis, lower surface of the present embodiment, the fixture above of other size of can also transferring, to complete the vibration test of other products.

In figure: 1-upper surface, 2-lower surface, 3-sidewall, 4-reinforcement, 5-shake table, 6-testpieces, 7-cooling water channel.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
The present embodiment provides a kind of water-cooling type high temperature vibration test fixture, and its structure as shown in Figure 1, comprises and arranges the upper surface 1 of cooling water channel, the lower surface 2 being connected with shake table 5 table tops and the sidewall 3 and the reinforcement 4 that connect upper and lower end face;
On upper surface 1 and lower surface 2, be equipped with a plurality of installing holes, the installing hole of upper surface 1 is for installation test part 6, and the installing hole of lower surface 2 is used for installing shake table 5; On sidewall 3, edge is circumferentially evenly provided with the reinforcement 4 of one or more connections upper surface 1 and lower surface 2; The length and width of upper surface 1 are of a size of 1136*450mm, and wall thickness is 30mm; Lower surface 2 external diameters are 640mm, and thickness is 25mm; Reinforcement 4 thickness 20mm; The thickness of upper surface 1 and lower surface 2 and the proportionate relationship of Rib Thickness are about 6:5:4.
Reinforcement 4 is all provided with knuckle with upper surface 1, lower surface 2 cohesive positions, and the diameter of knuckle is for being more than or equal to 10mm, and the quantity of reinforcement 4 is 8.
1 inside, upper surface arranges many cooling water channels 7, and it distributes as shown in Figure 2, and the internal diameter of cooling water channel is 10mm.In use, cooling water channel inside passes into cooling water, and cooling water is taken away the heat that testpieces 6 passes to high-temperature vibrating test fixture, keeps its temperature below 200 ℃.
The shape of the shape of upper surface 1 and testpieces 6 adapts, and is the semicircle shape that adds supported on both sides plate in the present embodiment; The shape of the shape of lower surface 2 and shake table 5 adapts, and is circular in the present embodiment.1 middle part, upper surface and sidewall 3 middle parts have circular hole, for drawing sensor measurement wire, also for lifting operation, provide the hole of binding suspender belt simultaneously.
