Description
Technical field
The utility model relates to a kind of locking device of machine tool guideway, relates in particular to a kind of oblique contract supercharging locking device for machine tool guideway.
Background technology
At present the track locking device that uses is directly to exert pressure to latching ram by pressure medium such as compressed air or pressure oil, make it compress track, realize locking function, pressure and stability requirement to pressure source are higher, and the pressure that guide rail obtains is limited, the integral rigidity of lathe in working angles is relatively poor, influences product quality.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, under not change condition of pressure source, improves the chucking power of guide rail, guarantees pressure and the stability of pressure source, can strengthen the oblique contract supercharging locking device of the integral rigidity in the machine cut process.
The technical solution of the utility model is a kind of oblique contract supercharging locking device, it comprises machine tool guideway 1, it is characterized in that: at described machine tool guideway 1 slide 2 is installed, in described slide 2 and on the top of described machine tool guideway 1, be provided with piston cavity 3, be provided with piston rod 4 in the described piston cavity 3, left end at described piston rod 4 is provided with oil-in or the air inlet that is connected with described piston cavity 3, be provided with the interface channel 5 that is connected with described machine tool guideway 1 in the described piston cavity 3, being provided with inclined groove 8, one inclination latching rams 6 in the bottom of described piston rod 4 is arranged in the described interface channel 5 and the inclined planes of described latching ram 6 closely contact with the inclined plane of described groove 8.
The technical solution of the utility model can also be to be provided with spring 7 between the end plug 9 of the left end of described piston rod 4 and described piston cavity 3.
The beneficial effects of the utility model are by at described machine tool guideway 1 slide 2 being installed, in described slide 2 and on the top of described machine tool guideway 1, be provided with piston cavity 3, be provided with piston rod 4 in the described piston cavity 3, left end at described piston rod 4 is provided with oil-in or the air inlet that is connected with described piston cavity 3, be provided with the interface channel 5 that is connected with described machine tool guideway 1 in the described piston cavity 3, being provided with inclined groove 8, one inclination latching rams 6 in the bottom of described piston rod 4 is arranged in the described interface channel 5 and the inclined planes of described latching ram 6 closely contact with the inclined plane of described groove 8; During use, under not change condition of pressure source, piston rod 4 displacement to the right in the piston cavity 3, owing to be provided with inclined groove 8 in the bottom of piston rod 4, one inclination latching ram 6 is arranged in the described interface channel 5 and the inclined plane of described latching ram 6 closely contacts with the inclined plane of described groove 8, that is to say: the inclined ramp by piston rod 4 closely contacts with the inclined ramp of latching ram 6, amplified the power that acts on the machine tool guideway 1, its mechanics principle N=1/tan θ, θ is the angle of inclination of groove 8, like this, realized under not change condition of pressure source, improve the chucking power of guide rail, guarantee pressure and the stability of pressure source, can strengthen the effect of the integral rigidity in the machine cut process.
