The utility model discloses a realize above-mentioned purpose through following technical scheme:
this a hydraulic means for numerical control lathe tailstock comprises tailstock, flange, hydro-cylinder, tailstock sleeve, the cover seat that rises, the cover and the nut that rises, and the tailstock passes through the fix with screw on the lathe bed, its characterized in that: the right end of the tailstock is fixedly provided with an oil cylinder through a connecting flange; the left end part of the tailstock is provided with an expansion sleeve seat, and an expansion sleeve is arranged in the expansion sleeve seat; the inside of tailstock installs the tailstock sleeve, and the telescopic right-hand member of tailstock is connected with the piston rod of hydro-cylinder through the nut, and the telescopic left end suit of tailstock is in the cover that rises.
The tailstock sleeve ensures centering precision by adjusting the fit clearance between the tailstock sleeve and the expansion sleeve.
The piston rod of the oil cylinder is controlled to stretch out and draw back by a numerical control system of the numerical control lathe, and when the piston rod stretches out, the oil cylinder drives the tailstock sleeve to stretch out by a nut; when the piston rod of the oil cylinder retracts, the oil cylinder drives the tailstock sleeve to retract through the nut.
Compared with the prior art, the utility model beneficial effect lie in:
this a hydraulic means for numerical control lathe tailstock promotes the telescopic centering precision of tailstock through the adjustment of cover and tailstock sleeve fit clearance that rises, even the tailstock sleeve appears wearing and tearing, also can adjust through the cover that rises, ensures the running accuracy of tailstock. The oil cylinder is controlled to be incorporated into a numerical control system of the numerical control lathe, and the action of the oil cylinder is controlled to realize the automatic extension and retraction of the tailstock sleeve; and the operation is quick and convenient, the time and the labor are saved, and the production efficiency is improved. The problems that the conventional manual hand wheel rotates to drive the tailstock sleeve to stretch out, retract and lock are troublesome in operation, time and labor are wasted, the production efficiency is low, and the running precision is difficult to guarantee are solved.
Drawings
Fig. 1 is a schematic structural diagram of a hydraulic device for a tailstock of a numerically controlled lathe.
In the figure: 1. the tailstock comprises a tailstock, 2, a connecting flange, 3, an oil cylinder, 4, a tailstock sleeve, 5, an expansion sleeve seat, 6, an expansion sleeve, 7, a nut, 8 and a lathe bed.
Detailed Description
The embodiment of the hydraulic device for the tailstock of the numerically controlled lathe is further described in detail in the following with reference to the attached drawings:
this a hydraulic means for numerical control lathe tailstock comprises tailstock 1, flange 2, hydro-cylinder 3, tailstock sleeve 4, cover seat 5 rises, cover 6 and nut 7 rise, tailstock 1 passes through the fix with screw on lathe bed 8, the right-hand member of tailstock 1 is equipped with hydro-cylinder 3 through flange 2 is admittedly, cover seat 5 rises is equipped with to the left end of tailstock 1, it installs cover 6 to rise in the cover seat 5, the internally mounted of tailstock 1 has tailstock sleeve 4, the right-hand member of tailstock sleeve 4 is connected with the piston rod of hydro-cylinder 3 through nut 7, the left end suit of tailstock sleeve 4 is in cover 6 rises. The tailstock sleeve 4 ensures centering precision by adjusting the fit clearance between the tailstock sleeve and the expansion sleeve 6. The piston rod of the oil cylinder 3 is controlled to stretch out and draw back by a numerical control system of the numerical control lathe, and when the piston rod stretches out, the oil cylinder 3 drives the tailstock sleeve 4 to stretch out through the nut 7; when the piston rod of the oil cylinder 3 retracts, the oil cylinder 3 drives the tailstock sleeve 4 to retract through the nut 7 (see the attached figure 1).
This a hydraulic means for numerical control lathe tailstock is on the basis of original ordinary tailstock, demolishs lead screw and hand wheel on the original tailstock, through changing dress flange 2, hydro-cylinder 3, tailstock sleeve 4, the cover seat 5 that rises, the cover 6 and the nut 7 that rises, uses the existing hydraulic pressure station of numerical control lathe and numerical control system simultaneously, increases hydraulic circuit all the way again, can realize the hydraulic drive of ordinary tailstock. An added hydraulic circuit is controlled by a numerical control system; the machining process of the tailstock sleeve 4 is automatically completed through programming.
The working principle of the hydraulic device for the tailstock of the numerically controlled lathe is as follows:
when a numerical control system sends an extending instruction to the tailstock sleeve 4, the electromagnetic directional valve of the hydraulic station acts, the oil cylinder 3 acts, the piston rod of the oil cylinder 3 extends out, the tailstock sleeve 4 is driven to extend out through the nut 7, and the action of tightly pushing a workpiece is completed. Similarly, when the numerical control system sends a tailstock sleeve 4 retraction instruction, the hydraulic station electromagnetic directional valve is reversed, the oil cylinder 3 acts, the piston rod of the oil cylinder 3 retracts at the moment, the tailstock sleeve 4 is driven to retract through the nut 7, and the workpiece is loosened.
After the tailstock sleeve 4 extends out, when the positioning concentricity is reduced, the expansion sleeve 6 is properly compressed, so that the fit clearance between the expansion sleeve 6 and the tailstock sleeve 4 is reduced, and the concentricity can be improved.
This a hydraulic means for numerical control lathe tailstock realizes the action automation of tailstock sleeve 4, brings numerical control system control through hydraulic system, and labour saving and time saving has improved production efficiency greatly, and the operation is swift convenient. The structure adjustment of the expansion sleeve 6 changes the clearance fit between the expansion sleeve and the tailstock sleeve 4, the running precision of the tailstock is powerfully guaranteed, and even if the tailstock sleeve 4 is worn, the precision can be adjusted through the expansion sleeve 6.
