Abstract
The utility model relates to a workbench with a floating support mechanism. The workbench comprises a workbench, a rotary table and a main body piston. The lower part of the workbench is connected with the rotary table. A slider seat is positioned under the rotary table. The center of the rotary table is provided with the main body piston with a piston cover. The inner side of the main body piston is provided with a rotary shaft. The rotary table positioned on the periphery of the rotary shaft is equidistantly and respectively provided with four floating support oil cylinders which are provided with split pistons. The split pistons are packaged in the floating support oil cylinders. The side faces of the split pistons are provided with limit pins. Needle roller bearings are positioned above the split pistons. The lower part of the floating support oil cylinders is connected with an oil pipe at the lower side. The workbench has the advantages that the floating support oil cylinders are used to increase the weight bearing ability of the workbench, namely, the workbench keeps fast rotation speed when being heavily loaded; as the four floating support oil cylinders and the main body piston are lifted at the same time, and the lifting heights are the same, no deflected swing is ensured to happen to the workbench.
Description
Technical field
The utility model relates to machine tool field, relates in particular to a kind of workbench with unsteady supporting mechanism.
Background technology
At present, rotating shaft in the middle of the support component of the workbench of lathe horizontal Machining centers mainly depends on is when workbench carrying workpiece is heavier, in the course of the work, workbench lifts rotation will produce the beat phenomenon, and rotary speed is slow, the damage of rotating shaft in the middle of permanent use can cause.
The utility model content
The purpose of this utility model provides a kind of workbench with unsteady supporting mechanism, to overcome auxiliary supporting mechanism of lacking of work on hand platform, easily to produce beat phenomenon, the rotary speed slower deficiency of workbench when bearing a heavy burden when workbench rotates.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of workbench with unsteady supporting mechanism, comprise workbench, turntable, main body piston, the workbench bottom connects turntable, the turntable below is provided with slide, and the center position of turntable is provided with the main body piston that has piston cap, and the inboard of main body piston is provided with rotating shaft, be with helical gear in the slide of main body piston outside, helical gear top is with fluted disc and lower tooth disk respectively, and the both sides of main body piston connect oil suction chamber, and oil suction chamber is communicated with the downside oil pipe; The turntable equal intervals of rotating shaft periphery is respectively equipped with four unsteady support cylinders, and unsteady support cylinder is positioned at the periphery of fluted disc and lower tooth disk; Each unsteady support cylinder is equipped with the split piston, described split piston is loaded on the support cylinder inside of floating, be with the O RunddichtringO between split piston and the unsteady support cylinder inwall, the side of split piston is provided with the spacer pin that is used to prevent its rotation, needle bearing is equipped with to guarantee turntable flexible rotation up in the top of split piston, the top of unsteady support cylinder is provided with straight pin, the front end of straight pin is equipped with gland, the top of unsteady support cylinder is fixed by lock screw, and the lower end of each unsteady support cylinder connects the downside oil pipe.
Beneficial effect with workbench of unsteady supporting mechanism described in the utility model is: set up the lifting capacity that the support cylinder that floats strengthens workbench, promptly workbench still can keep rotating speed faster when bearing a heavy burden; Four split pistons of periphery lift simultaneously with the main body piston, and the height unanimity of lifting, and can guarantee steady, the no beat phenomenon of workbench rotation.
