4, be the web joint connection above the balance staff case, rigidity is relatively poor;
5, left and right sides balance staff case separate machined, the precision that the hole of balance staff is installed is difficult to guarantee.
For growing science and technology, the structure of traditional Charpy impact machine tester can not adapt to the demand of especially big energy impact test.
The utility model content
The utility model is unreasonable in order to solve existing Charpy impact machine tester structural design, can not bear the technical matters of especially big energy impact test, and the Charpy impact machine tester of a kind of reasonable in design, rigidity height, easily manufactured especially big energy is provided.
For addressing the above problem, the technical solution of the utility model is the Charpy impact machine tester of a kind of especially big energy of structure, and it comprises mainframe, is located at the balance staff case and the balance staff on mainframe top, hangs on the pendulum on the balance staff, drive unit, the anvil device of being located at the mainframe bottom that the driving balance staff rotates, the extension pendulum device of being located at mainframe top.Described mainframe comprises base plate and is located at a pair of chevron shaped column of being made by section bar on the base plate that described balance staff case is " ∩ " type structure that one designs and produces.
Preferred version of the present utility model, the base plate between described two columns are provided with the retracting device of collecting the incomplete sample after testing.
One side of described balance staff case is provided with the moving brake gear that stops of the described balance staff of may command.
The other end of the balance staff case that links to each other with described drive unit is provided with display device, also is provided with before this heel post corresponding to the sample conveying device of described anvil device and the control box of accessory drive motion.
Be provided with protective cover between described two columns.
The utility model adopts section bar to manufacture chevron shaped column, makes testing machine structure simple, is particularly useful for the testing machine of large scale structure; Base plate and column can adopt the material of varying strength and rigidity, so that can reduce material cost; Base plate, column, balance staff case are separately made, and are convenient to processing, and precision guarantees easily; Each visible surface of base plate, column, balance staff case all can be processed, specious easy assurance; The making that is the integrated design of balance staff case, rigidity height, the machining precision that the hole of balance staff is installed guarantee easily; Each part can install earlier in advance on ground in the balance staff case, and integral hoisting is convenient to install to column again.It is unreasonable that the utility model has overcome existing Charpy impact machine tester structural design effectively, can not bear the technological deficiency of especially big energy impact test.
