Description
Technical field
The utility model relates to a kind of support equipment of pressure testing machine, is specifically related to a kind of pressure testing machine top board bulb auxiliary structure.
Background technology
Pressure testing machine is the important tests equipment of material mechanical performance test, and function is that sample is applied and presses to load and measure the mechanical property of sample material under test load.Upper lower platen as pressure part is very important, because specimen surface has processing irregularity, causes the uneven situation of bearing surface, so must adopt bulb pressure plate structure.Consider compact conformation, be convenient to load and unload sample, finishing face keeps the factor such as clean, generally ball head is divided and be arranged on top board part.
As shown in Figure 1, existing structure is for to be fixed on ball-and-socket 201 on main frame, on described ball-and-socket, there are two sections of arc surfaces, be ball-and-socket spherical outside surface 201a and ball-and-socket Internal Spherical Surface 201b, on boatswain chair, there is the cambered surface identical with ball-and-socket spherical outside surface, ball-and-socket Internal Spherical Surface 201b presses and puts on bulb pressing plate 205, between boatswain chair and bulb pressing plate, by screw 206, connect, between boatswain chair and ball-and-socket spherical outside surface 201a, be formed with gap 301, between boatswain chair and bulb pressing plate, be formed with gap 302, this structure has been fixed to top board bulb pressure plate structure, if in calibration process, the inner existing ball head device of proving ring, just easily produce nominal data unstable, the result of power value misalignment, therefore, single pressure plate structure cannot meet the various testing requirementss of client.If design a kind of upper bulb pressing plate, can select whether use ball head structure according to actual operation requirements, will greatly increase use flexibility ratio like this, also guaranteed the precision of complete machine power value.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pressure testing machine top board bulb auxiliary structure, can, according to actual tests needs, in bulb pressing plate and fixation clip, freely switch.
The technical scheme that the utility model addresses the above problem is as follows:
A pressure testing machine top board bulb auxiliary structure, comprises ball-and-socket, boatswain chair and bulb pressing plate, and described ball-and-socket has ball-and-socket spherical outside surface and ball-and-socket Internal Spherical Surface,
Described ball-and-socket Internal Spherical Surface is pressed on bulb pressing plate, described boatswain chair is pressed on ball-and-socket spherical outside surface, between boatswain chair and ball-and-socket spherical outside surface, is formed with the first gap, between boatswain chair and bulb pressing plate, is formed with the second gap, between boatswain chair and bulb pressing plate, be connected with screw, it is characterized in that:
Described ball-and-socket periphery is provided with set nut, and between described ball-and-socket and set nut, for being threaded, the height of set nut is less than set nut upper surface to the distance between boatswain chair upper surface.
Further, in order to facilitate rotational lock nut, the two ends of described set nut are provided with handle.
Further again, when set nut upper surface is concordant with ball-and-socket upper surface, the gap length between described set nut lower surface and boatswain chair is preferably 5mm.
Principle of work of the present utility model is, when needs are used bulb pressure plate structure, by rotating handles, to make to have between set nut and boatswain chair the gap of 5mm.Like this, can allow boatswain chair to have certain inclined spaces, form top board ball head device; When needs fixation clip structure, by rotating handles, make set nut be close to boatswain chair.Like this, there is not inclined spaces in boatswain chair, and bulb pressing plate is fixed.
Compare with existing top board bulb auxiliary structure, the beneficial effects of the utility model are as follows: this utility model can be carried out different tests as required, expanded the use function of top board bulb auxiliary structure, guaranteed the precision of complete machine power value.
