Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Elaborate a lot of detail in the following description so that fully understanding this utility model, but this practicality is new
Type can also use other to be different from alternate manner described here to implement, and those skilled in the art can be without prejudice to this reality
Doing similar popularization in the case of novel intension, therefore this utility model is not limited by following public specific embodiment.
As it is shown in figure 1, the utility model discloses a kind of angled end-face sample hardness test auxiliary device, including base 1, erect
To being arranged on four hollow columns 2 of base 1 upper surface and being fixedly mounted on the support means in the middle part of base 1, described hollow vertical
The endoporus of post 2 is screwed hole, and installation hold-down bolt 6(supporting with screwed hole sees accompanying drawing 2), hollow column 2 top is additionally provided with borrows
Helping the fixing pressing plate 7 of hold-down bolt 6, described support means top is by means of spherical pair connecting trays 5；Described four hollow vertical
Post 2 is relative to the square laying in base 1 center, and described support means is fixedly mounted on base 1 center；Described support fills
Put and include cylindrical support 3 and adjustment plate 4, axial threaded hole, described adjustment plate 4 following table are set in the middle part of described cylindrical support 3
Face arranges screw rod, and described screw rod coordinates with axial threaded hole.
The described adjustment plate 4 axially mounted vertical rod of upper surface, rod end fixed installation steel ball 8(sees accompanying drawing 3), described torr
