Embodiment
The utility model is a kind of high rigidity, high-speed, stable and be easy to the testing machine framed structure of processing and installing, to be used for satisfying special material to the requirement of high-speed test (HST).
Below in conjunction with drawings and Examples the utility model is done specific descriptions.
Figure 1 shows that structural representation front view of the present utility model.
Figure 2 shows that the attached view of structural representation of the present utility model.
The utility model comprises 1 entablature, 2 leading screws, 3 risers, 4 guide rail slide blocks, 5 middle cross beams, 6 guide rails, 7 bearing pins, 8 locating pieces and 9 bases.
The relative position of described entablature 1 and base 9 is provided with mounting groove, riser 3 uses screw to be vertically fixed between base 9 and the entablature 1 by this mounting groove, the central axis that can guarantee riser 3 can overlap with both, improves the coupling stiffness of general frame, prevents riser 3 distortion that twists; During installation, the two ends of riser 3 snap onto in the mounting groove, and outside surface size and the mounting groove of riser 3 have certain clearance fit, and the fastening verticality of adjusting riser 3 and base 9 by set screw has guaranteed the fastness of three after connection.
For ease of adjust riser 3 when mounted with the verticality of base 9, riser 3 adopts trapezoidal design with the attachment screw of base 9, when finely tuning, the connected mode of trapezoidal design all can reach the effect of adjustment on all directions.
Between described riser 3 and the base 9 locating piece 8 is installed, prevent in transportation or be collided, when falling, riser 3 loses and the initial vertical precisions of installing of base 9.
Be processed with the vertical plane of accurate vertical precision on two joint faces of described locating piece 8, two joint faces are connected with base with riser 3 respectively and are connected, and guarantee in the course of work, and riser 3 is constant with the verticality of base 9.
Also be provided with guide rail 6 between described entablature 1 and the base 9, guide rail 6 is vertical state and is installed on the riser 3 with accurate vertical precision by screw, guide rail 6 radially, anti-radially, side direction all has certain load-bearing capacity, and rigidity is better, guide rail parameter by accurate Calculation, under the large load of crossbeam, high-speed cruising, still can guarantee crossbeam stable and vertical accurately.
For the central axis of assurance guide rail 6 and the dead in line of riser 3, on the described riser 3 bearing pin 7 is installed, guide rail 6 is by the periphery location of bearing pin 7; During installation, the side of guide rail 6 is abutted against on two bearing pins 7 on the riser 3, guarantee that guide rail 6 center lines and the center line of testing machine have certain coaxiality error, but improve stability and the load-bearing capacity of crossbeam operation, fastening bolt is finished the installation of guide rail 6 at last.
Also be provided with leading screw 2 between described entablature 1 and the base 9, leading screw 2 is connected with entablature by bearing and base 9 and is connected and fixing; When leading screw 2 was installed, its installation accuracy was to cooperate by the hole of its cylindrical with entablature 1 and base 9, thereby the central axis that guarantees leading screw 2 is parallel with the axis of guide rail 6.
Described leading screw 2 is provided with middle cross beam 5, is positioned at the hole at middle cross beam 5 middle parts and is connected with screw cylindrical on the leading screw 2, and connect by screw fastening; The rear end face of middle cross beam 5 is connected with guide rail slide block 4, and the hole at the rear end face of middle cross beam 5 and its middle part has strict tolerance in distance, thereby after guaranteeing middle cross beam 5 installations, the axis of the workplace of guide rail 6 and leading screw 2 has strict parallel accuracy.
