Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
In the present embodiment, as shown in Figure 1, floating installation provided by the invention, comprises base 1, sleeve 2, suspension seat 7, regulates spacing module 14, free floating module 15, cushions locating module 13 and the module 12 that fluctuates;
Wherein, described suspension seat 7 is arranged on the upside of described base 1; Described sleeve 2 is arranged on the outside of base 1 and suspension seat 7; Base 1 and suspension seat 7 described in the spacing model calling of described adjustment, for controlling the pendulum angle of suspension seat 7; Described free floating module installation between base 1 and suspension seat 7, for translation and the swing of the seat 7 that suspends; Described buffering locating module is arranged in the first endoporus on the sidewall of sleeve 2, for buffering location and the self-centering of the seat 7 that suspends; In the second endoporus that the module installation that fluctuates is arranged in the upper surface of suspension seat 7, for cushioning the active force to suspension seat 7 upper surface.
The spacing module of described adjustment comprises protective sleeve 4 and locking nut 3; Wherein, the bottom of protective sleeve 4 is threaded with base 1, and described suspension seat 7 is blocked on the top of protective sleeve 4; Locking nut 3 screws height for what limit protective sleeve 4 and base 1.Described free floating module comprises large steel ball 6 and little steel ball 5; The center of the upper surface of base 1 is provided with central recess, the circumferential direction of the upper surface of base 1 evenly to be arranged three little grooves; Described large steel ball 6 is arranged in central recess, and described little steel ball 5 is arranged in little groove.Buffering locating module comprises the first buffer spring 8 and protection screw 9; Wherein, uniform three the first endoporus running through the sidewall of sleeve 2 in the upper circumferentially direction of the sidewall of sleeve 2; First buffer spring 8 and protection screw 9 are installed in the first endoporus and the first buffer spring 8 is arranged between suspension seat 7 and protection screw 9.The module that fluctuates comprises the second buffer spring 10 and buffer stopper 11; Second buffer spring 10 and buffer stopper 11 are all arranged in the second endoporus, and buffer stopper 11 is arranged on the upside of the second buffer spring 10.Described sleeve 2 is threaded with between base 1; Being matched in clearance between described sleeve 2 and described suspension seat 7, providing headspace for realizing float function.The upper surface of described sleeve 2 offers relief hole.
Structural principle of the present invention and use procedure are: by the module that fluctuates, cushion locating module, regulate spacing module and free floating module, realize product float function in the course of the work.Four module implementation procedures are as follows: free floating functions of modules is contacted by the some face formed between suspension seat 7 bottom surface and the peak of large steel ball 6, realizes translation and the swing of suspension seat 7 in the course of the work, thus reaches the free floating function of project expection; And for rotating produced moment of torsion in the course of the work, little steel ball 5 serves the effect reduced friction.Meanwhile, in order to effectively control oscillating quantity and the pendulum angle of suspension seat 7, protective sleeve 4 structure is set; Adjustment protective sleeve 4 screws height with the little outer round thread of base 1, and carries out self-locking by locking nut 3, and restriction screws height, thus the oscillating quantity of control suspension seat 7 and pendulum angle, protect suspension seat 7 in the course of the work, finally play and regulate spacing module effect.Sleeve 2 outer wall circumferencial direction is evenly equipped with three threaded interior holes, for installing buffer spring 8 and protection screw 9, by the thread depth of respectively three, regulating circumferential direction protection screw 9 during prepackage, the workpiece and the frock axis that make to be positioned over suspension seat 7 inside meet axiality requirement; Suspension seat 7 in working order under, by free floating with regulate the acting in conjunction of spacing module, realize float function, and utilize the elastic shrinkage function of buffer spring 8 can play buffering location and self-centering function, finally play and cushion locating module effect.On the other hand, because workpiece exists size cumulative errors, may to damage baseplane in axial feed process to prevent from being arranged on plug on main shaft, suspension seat 7 upper surface circumferencial direction is evenly equipped with three circular holes, for installing buffer spring 10 and buffer stopper 11, wherein, buffer stopper 11 all belongs to matched in clearance with the circular hole of suspension seat 7, and its upper surface is a little more than the upper surface of suspension seat 7; When the active force produced to lower feeding is excessive, utilize the elastic shrinkage function of buffer spring 10, produce reaction force upwards, utilize the gap existed between the circular hole of buffer stopper 11 and suspension seat 7 simultaneously, finally realize fluctuating module effect.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
