    A very stiff mounting device, particularly for a machine tool or measuring instrument, is constructed from six rod-like members the ends of which are rigidly coupled together to form a tetrahedral structure and mounting means comprising a rigid member fixedly coupled to three of said rod-like members said three rod-like members not being co-planar.

    专利说明:

    The invention relates to mechanical engineering and can be used in the field of metrology and in precision machine tools.
    The purpose of the invention is to increase the degree of rigidity of the device by reducing the effect of destabilizing forces.
    FIG. 1 shows a tetrahedral mounting device for a machine, a partially broken-out plan view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a cross-section of the FIG. 3; in fig. 6 - the connection of the t-shaped elements by means of pins; in fig. 7 - the same. by welding; in fig. 8 - damping elements used in connecting the mt-like elements; in fig. 9 is a device with additional stiffening elements, a plan view.
    The tetrahedral installation structure includes six tons of similar elements 1. Each element contains tubular external compressive elements (spacers) 2, inside which stretch rods 3 are located along the entire length 3. There is a floor at each vertex of the tetrahedral design sphere 4. Each sphere contains a pair of conjugated hemispheres 5 and 6. Half of the hemispheres are held together by threaded bolts 7.

    Each sphere abuts against the outer compressive elements 2 of the three docked tri-shaped elements and is pressed against them by means of screws 8 connected to the ends of the corresponding tensile rod 3 enclosed in the tubular element. At a distance from the base, on the tongue-like elements, a tool holder 9 of the machine tool is mounted. The tool holder 9 is pressed to t-like elements with the help of threaded bolts 10 and gasket blocks 11. The tool holder has a hole 12 aligned with the main axis 13 of the machine through which the drive shaft 14 carries the rotating spindle 15 on the air lubricant and the grinding tool 16. On T-shaped base elements are mounted by a V-shaped guide 17, carrying the workpiece holder 18, to impart a linear movement of the workpiece 19 under the grinding tool 16. The guide has a hollow section 20, the wall thickness of which pae.ia wall thickness of other structural elements. The floor of the sphere 4, remote from the base, contains an opening 21 through which the drive shaft 14 passes.
    The ends of the tensile rod 3 do not abut spheres 4. This allows them to be tuned to resonance by adjusting the screws 8 so that they differ from the resonant frequency from the compression tube elements 2.
    According to the embodiment (Fig. 6), instead of the spheres in the vertices, the hinged joints in the form of pins 22 are used to join the two like-elements 1.
    According to another embodiment (Fig. 7), instead of spheres at the vertices, a common connection 23 is used.
    The gap between the rods 3 and the tubular elements 2 may contain a viscous fluid 24 (Fig. 8) for damping.
    Preferably, all the elements of the device are made of a material with the same expansion coefficient and the same cross section to balance the thermal response rates.
    All t-shaped elements are preferably of the same size. It is possible that t-like elements of g & oh groups (forming the base and faces of the tetrahedron) are made of different sizes. In that case will take place
    equilateral construction, not equilateral.
    The machining (or other operation) is performed near the main axis of the machine in order to minimize the deformation effect.
    Other forms of guide may be used.
    The linear motion guide and the means for fastening the sample are connected to the driving means.
    Additional rigidity can be given to t-like base elements 1 with the help of an additional pipe 25 screwed on or mounted on the underlying side of the elements (Fig. 9).
    It is advantageous to create vibration damping with the help of Means 26 at the assembly points of the connection of t-like support elements.
    The use of installation devices is not limited to processing machines. They can be used in any field, for example in metrology, where a high degree of rigidity and strength is required.
