Abstract
The invention relates to an ejecting and supporting device for a long and thin shaft. The ejecting and supporting device comprises a machine tool body, three-jaw chucks arranged at the two ends of the machine tool body in the long shaft direction, a jacking device and supporting devices. A pair of guide rails is arranged at the upper end of the machine tool body in the long shaft direction. The jacking device comprises a supporting column and a clamping cover. The bottom end of the supporting column is matched with the guide rails in an embedded manner, and the clamping cover is fixed to the upper end of the supporting column. The clamping cover is in the shape of a circular platform, and a circular-platform-shaped cavity is formed in the middle of the clamping cover. The supporting devices comprise stand columns fixed between the guide rails, and arc blocks at the top ends of the stand columns. The arc blocks are in one quarter arc shapes, and the bottom ends of the arc blocks are welded to the upper ends of the stand columns. The ejecting and supporting device has the beneficial effects that the clamping cover with the circular-platform-shaped cavity is adopted in the jacking device of the ejecting and supporting device for the long and thin shaft, the shaft stretches into the clamping cover by a certain depth according to the diameter of the shaft, complete clamping is not needed, and it can be guaranteed that the shaft cannot swing during rotating; and meanwhile the supporting devices support rod pieces, whether the shaft is bent or not can be effectively judged, and it can be avoided that the shaft is fractured or bent to a certain degree.
Description
Technical field
The present invention relates to a kind of slender axles and hold out against bracing or strutting arrangement, belong to mechanical equipment technical field.
Background technology
In machinery production process, the main working shaft-like part of lathe, and the production and processing of thin and long shafts part in lathe is relative difficulty.
The processing of traditional thin and long shafts part adopts one end to clamp, the mode that one end holds out against, and can not judge owing to holding out against intensity, is easy to fracture or bending occur, unreasonable structure in process; Simultaneously traditional mode that holds out against adopts top, holds out against inconvenience for thin and long shafts part, is therefore badly in need of development a kind of rational in infrastructure and hold out against slender axles easily and hold out against bracing or strutting arrangement, through retrieval, does not find the same or analogous technical scheme with the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rational in infrastructure and hold out against slender axles easily and hold out against bracing or strutting arrangement.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of slender axles hold out against bracing or strutting arrangement, and its innovative point is: comprise machine body, be arranged on the scroll chuck at machine body long axis direction two ends and holding device, be arranged on bracing or strutting arrangement between scroll chuck and holding device;
Described machine body upper end edge long axis direction arranges pair of guide rails;
Described holding device comprises support column, point to the card cover of scroll chuck perpendicular to support column; Described support column bottom coordinates with pair of guide rails is embedded, the fixing card cover in upper end; Described card cover is in circular platform type, and there is a circular platform type cavity at middle part, and cavity axis and scroll chuck axis place on the same line, and are parallel to pair of guide rails;
Described bracing or strutting arrangement comprises the arc block being fixed on the middle column of pair of guide rails, column top; Described arc block is 1/4 circular arc, and bottom is welded on column upper end.
Further, described column arranges an arrangement for adjusting height.
Further, described bracing or strutting arrangement arranges 2 ~ 3.
The invention has the advantages that:
1) slender axles hold out against bracing or strutting arrangement and mainly comprise scroll chuck, holding device and bracing or strutting arrangement, holding device adopts the card cover with circular platform type cavity, extend into according to the diameter of axle in the certain depth of card cover, do not need to clamp completely, do not shake when also can ensure that axle rotates; Bracing or strutting arrangement supports rod member simultaneously, effectively can differentiate whether axle bends, and also can avoid axle that fracture or bending occurs to a certain extent;
2) column is arranged an arrangement for adjusting height, carry out the lifting of stem height according to the change of the diameter of axle, simultaneously leave microscopic spaces between the arc block of column upper end and cylinder to be processed, vibrational power flow is reasonable;
3) whether bracing or strutting arrangement arranges 2 ~ 3, produce bend and can effectively differentiate axle various piece.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of slender axles of the present invention hold out against bracing or strutting arrangement.
Fig. 2 is the structural representation that a kind of slender axles of the present invention hold out against the bracing or strutting arrangement of bracing or strutting arrangement.
Detailed description of the invention
As depicted in figs. 1 and 2, the invention discloses a kind of slender axles and hold out against bracing or strutting arrangement, comprise machine body 1, be arranged on the scroll chuck 3 at machine body 1 long axis direction two ends and holding device, be arranged on bracing or strutting arrangement between scroll chuck 3 and holding device.
Machine body 1 upper end edge long axis direction arranges pair of parallel guide rail 2.
Holding device comprises support column 4, point to the card cover 5 of scroll chuck perpendicular to support column 4; Support column 4 bottom coordinates with pair of guide rails 2 is embedded, and card cover 5 is fixed in upper end; Card cover 5 is in circular platform type, and there is a circular platform type cavity 6 at middle part, and cavity 6 axis and scroll chuck 3 axis place on the same line, and are parallel to pair of guide rails 2.
Bracing or strutting arrangement comprises the arc block 8 being fixed on the middle column 9 of pair of guide rails 2, column 9 top; Column 9 sidewall is arranged an arrangement for adjusting height 10, arc block 8 is in 1/4 circular arc, and bottom is welded on column 9 upper end, and this bracing or strutting arrangement arranges 2 ~ 3 between scroll chuck 3 and holding device.
When slender axles hold out against bracing or strutting arrangement use, be clamped in scroll chuck 3 by slender axles 7 one end, one end is arranged in card cover 5, and moves holding device along pair of guide rails 2, and card cover 5 does not need to hold out against slender axles 7 completely, can stay certain space; Simultaneously according to the diameter of slender axles 7, utilize the height of arrangement for adjusting height 10 fine adjustments bracing or strutting arrangement.
More than show and describe general principle of the present invention and principal character.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
