Abstract
The utility model relates to a damping material supporting device. The damping material supporting device comprises a base which is connected with a tool guiding rail and a support which is fixedly arranged on the base, an oil cylinder is arranged on the support, a connecting plate which is connected through a guiding rod and the cylinder body of the oil cylinder is arranged on the upper end face of a piston rod of the oil cylinder, a groove hole is formed in the piston rod, a drivepipe and a shaft are placed in the groove hole, and a damping wheel is arranged on the upper end of the shaft. When tight supporting workpieces at a material supporting position is machined through the motion of a piston, the damping material supporting device utilizes a guiding effect of a cylindrical spiral compressing spring and the guiding rod and endured friction of rotation of the damping wheel along with the workpieces, thereby effectively balancing radial cutting force, resisting curvature and vibration of the workpieces in the process of turning, and guaranteeing machining precision of the workpieces. The damping material supporting device has the advantages of being simple in structure, reasonable, suitable for machining thin and long shaft type parts on a numerical control tool, capable of swiftly and conveniently adjusting the journey of the oil cylinder, and meeting requirements of machining the shaft type workpieces with multiple kinds of specifications.
Description
Technical field
The utility model relates to a kind of damping material-supporting device of lathe Auxiliary Functioning Unit structure, particularly a kind of controlled stroke.
Background technology
General numerically controlled lathe is when processing thin and long shafts part, because part poor rigidity, in the turning process, be easy to generate vibrations and crooked, the machining deformation phenomenon can take place inevitably, often occur phenomenons such as warpage, tapering be excessive during turning, make precision that workpiece can not obtain to expect and surface roughness and scrap.
Usually in the middle of machine tool accessories, centre frame is that processing is than the requisite selection of farm labourer's part.Adopt centre frame as supplemental support, but work in-process active balance radial cutting force, resist the crooked and vibrations of workpiece in turning process, increase the rigidity of workpiece and the stability of cutting, guarantee part processing precision, be a kind of effective way of processing thin and long shafts part, but often also be that processing cost is higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective of the prior art, a kind of crooked and vibrations that prevent in the turning process are provided, guarantee the machining accuracy of part, can realize the processing of thin and long shafts part on numerically controlled lathe, reduce the cost of Digit Control Machine Tool functional part, improved the damping material-supporting device of the processing characteristics of lathe greatly.
The purpose of this utility model is to realize by following technical proposals:
A kind of damping material-supporting device, it is characterized in that: comprise hard-wired support on a base that is connected with machine tool guideway and the base, on the described support oil cylinder is installed, the piston rod upper surface of this oil cylinder is equipped with the connecting plate that is connected with the cylinder body of oil cylinder by guide post, piston rod has slotted eye, lay sleeve and axle in the described slotted eye, the axle upper end is equipped with the damping wheel.
Between described sleeve and the axle cylindroid helical-coil compression spring is installed.
On the described piston rod inductance loop is installed, being connected near switch on this inductance loop and the support.
Damping material-supporting device of the present utility model adds man-hour pushing it to retainer position holder clamping of workpieces with piston motion, utilize guide effect and the damping wheel of guide post and cylindroid helical-coil compression spring to rotate the frictional force of bearing with workpiece, thereby active balance radial cutting force, resist the crooked and vibrations of workpiece in turning process, guaranteed the machining accuracy of workpiece.Of the present utility model simple and reasonable for structure, be applicable to the processing of thin and long shafts part on the numerically controlled lathe, and can satisfy the processing of plurality of specifications shaft-like workpiece by regulating the stroke of oil cylinder quickly and easily.Application of the present utility model can reduce the input of machine tool functional component, improves the workpiece machining accuracy, thereby brings certain economic benefits for manufacturing industry.
Description of drawings
Fig. 1 is the structural representation of the utility model damping material-supporting device.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is described.
As shown in Figure 1, damping material-supporting device of the present utility model comprises a base that is connected with machine tool guideway 1, and this base 1 is fastened on the lathe by wedge 14.Support 2 is welded on back processing on the base 1, connects cylinder body 3 by screw on the support 2.Be installed in piston rod 4 in the cylinder body 3 and upper flange 11, the lower flange 12 in cylinder body 3 outsides and form an oil cylinder with cylinder body 3.Piston rod is equipped with connecting plate 5 on 4 upper surfaces, and this connecting plate 5 is connected with cylinder body 3 by guide post 10.Have slotted eye on the end face of piston rod 4, sleeve 6 and axle 7 are installed in this slotted eye, axle 7 is installed in the sleeve 6 by axle and bearing block, and sleeve 6 and axle 7 be equipped with cylindroid helical-coil compression spring 9 each other, is used for back shaft and plays guide effect.Sleeve 6 is fixedlyed connected with connecting plate 5.Damping wheel 8 is installed in the upper end of axle 7, is used for carrying, holder clamping of workpieces.When piston rod 4 during in the limit inferior position, clamping workpiece, piston rod 4 moves to the retainer position, and damping material-supporting device holder clamping of workpieces begins processing.In process, the guide effect that the cylindroid helical-coil compression spring 9 in the sleeve 6 and the guide post 10 on the connecting plate 5 all can play the damping material-supporting device, damping wheel 8 rotates with workpiece, can bear bigger frictional force.Be equipped with on the support 2 adjustable position near switch 13, inductance loop 15 is installed on the piston rod 4, inductance loop 15 be connected near switch 13.Piston rod 4 optional position in stroke range all can be stopped by controlling standard near switch 13 and inductance loop 15, in order to satisfy the retainer scope of other specification axial workpieces.
