Abstract

The utility model relates to a rotatory oil tank buffer for a rotatory worktable, which comprises a rack, a front end cover and a tail end cover of the oil tank and a limit bolt. The limit bolt is connected with the front and tail end covers of the oil tank. The utility model is characterized in that damper rods are provided respectively on the front and tail end cover of the oil tank, with a damping hole provided on the limit bolt. A centerline of the damping hole, an axial lead of the end cover, an axial of the damp rod and an axial lead of the rack are in the same line. The utility model has the advantages of that the axiality between the damp rod and the outer circle of the rack is easily assured, which reduces the difficulty and cost during process as well as makes the control of the gap between the damping hole and the damp rod easier. The center of the limit bolt is coincident with the center of the rack, which increases the force-summing ability and reduces the abrasion. When the gap between the damping hole and the damp rod increases to a certain degree due to the abrasion, what needs to do is to replace the limit bolt, which causes a low cost.

Description

The angling cylinder buffer gear of rotary table
Technical field
The utility model relates to a kind of angling cylinder buffer gear that turns round the rotary table, particularly a kind of rotary table of the use of class multi-station machine tool.
Background technology
Rotary table is the indexing means of revolution class multi-station machine tool.During work, workpiece is installed on the table surface by anchor clamps, realizes the circular index location, thus the processing component that makes each station of lathe at a high speed, stable, finish the manufacturing procedure of each face of workpiece exactly.Angling cylinder is the actuator cylinder of table revolving movement, and it is a hydraulic jack.The piston rod of oil cylinder is provided with tooth bar, drives workbench by travelling gear and rotates.For preventing that tooth bar from producing impulsive force when moving forward and backward, two ends of oil cylinder are provided with buffer gear.Its buffer gear comprises stop screw, damper rod and the damping hole of tooth bar and oil cylinder two ends.Existing cylinder buffer mechanism as shown in Figure 1, the front and back ends that screw is located at oil cylinder respectively covers, preceding screw is provided with damper rod.Damping hole is located on the front end face of tooth bar, and the rear end face of tooth bar is a planar ends, the undamped hole, and back stop screw does not have damper rod, is planar end surface.The deficiency that this buffer gear exists: the one,, back stop screw does not have buffer gear, although the inertia that tooth bar retreats when resetting is little, impulsive force is also little, to some Precision Machining, still can affect to machining accuracy.The 2nd,, have damper rod on the front limit screw, and preceding damping hole is located on the tooth bar, owing to add the man-hour hole axiality of tooth bar cylindrical be cannot say for sure card, be easy to be obstructed when causing damper rod to insert damping hole or insert not advance, influence finishing of spacing action; If excesssive gap, then the back pressure in the damping hole is too small, does not have the effect of buffering again, thus the damage of aggravation components and parts.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes above-mentioned the deficiencies in the prior art, and a kind of angling cylinder buffer gear of rotary table is provided.
Technical solution of the present utility model is, the forward and backward end cap and the stop screw that comprise tooth bar, oil cylinder, stop screw is connected in front and back ends and covers, and it is characterized in that: be respectively equipped with damper rod on the front and rear end of tooth bar, as a whole of this damper rod and tooth bar; Stop screw is provided with damping hole, and the center line of its damping hole and the axial line of end cap are point-blank.
The axial line of the center line of damping hole and the axial line of end cap, damper rod and the axial line of tooth bar are all on same straight line.
The advantage that the utility model is compared with prior art had is:
(1) realized effective buffering to angling cylinder terminal point and original position two ends;
(2) have the front and back damper rod on the tooth bar, damper rod is easy to guarantee to the axiality of tooth bar cylindrical, has reduced the difficulty and the cost of processing, also is easy to control the gap of damping hole and damper rod, thereby guarantees buffering effect.
(3) center of stop screw overlaps with the center of tooth bar, and stress performance is good, no extra moment loading between damping hole and the bar, and it is little to wear and tear.
(4) when the gap between damping hole and the damper rod is increased to a certain degree because of wearing and tearing, only need to change stop screw and get final product, cost is very little.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 structural representation of the present utility model.
Number in the figure: 1-end cap, 2-stop screw, 3-damping hole, 4-damper rod, 5-tooth bar.
Specific implementation method
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Comprise the forward and backward end cap 1 and the stop screw 2 of tooth bar 5, oil cylinder, stop screw 2 is connected on the forward and backward end cap 1, it is characterized in that: be respectively equipped with damper rod 4 on the front and rear end of tooth bar 5, this damper rod 4 and 5 as a whole of tooth bars; Stop screw 2 is provided with damping hole 3, and the axial line of the center line of its damping hole 3 and end cap 1 point-blank.
The axial line of the axial line of the axial line of the center line of damping hole 3 and end cap 1, damper rod 4 and tooth bar 5 is all on same straight line.
During work, when tooth bar 5 advances near terminal point or retreats near original position, damper rod 4 inserts in the damping hole 3, oil in the damping hole 3 sees through slit very little between damper rod 4 and the damping hole 3 and overflows, thereby in damping hole 3, form back pressure, moving forward and backward of tooth bar 5 produced very big resistance, in very short distance, reduce the speed that tooth bar 5 advances or retreats rapidly.Stop screw 2 carries out when spacing before and after the step of tooth bar 5 bumps against, the percussion that can slow down 5 pairs of screws 2 of tooth bar, thus the relevant components and parts of protection are not damaged, and guarantee the high manufacturing accuracy of rotary table.All be threaded on the stop screw 2 of front and back, can regulate spacing position, nut is used for fixing spacing position.

Claims (2)

1, the angling cylinder buffer gear of rotary table, the forward and backward end cap and the stop screw that comprise tooth bar, oil cylinder, stop screw is connected in front and back ends and covers, and it is characterized in that: be respectively equipped with damper rod on the front and rear end of tooth bar, as a whole of this damper rod and tooth bar; Stop screw is provided with damping hole, and the center line of its damping hole and the axial line of end cap are point-blank.
2, the angling cylinder buffer gear of rotary table as claimed in claim 1 is characterized in that: the axial line of the center line of damping hole and the axial line of end cap, damper rod and the axial line of tooth bar are all on same straight line.
