Abstract
The utility model discloses an efficient special hole boring machine for a stern sheave, and relates to a special machine capable of boring shaft holes for the stern sheave used on a ship. The efficient special hole boring machine comprises a base, a sliding workbench and a feeding lead screw arranged on the base, wherein, the feeding lead screw is connected with a feed motor through a reduction gearbox; a guiding rail is arranged at the upper end of the base; a cycloidal speed reducer and a boring bar motor are arranged at the upper part of the sliding workbench, wherein, the cycloidal speed reducer and a universal joint coupling are connected; a feeding nut matched with the feeding lead screw is arranged at the lower part of the sliding workbench; and the sliding workbench is driven by the feeding lead screw so as to move along the guiding rail. The efficient special hole boring machine is easy to control when processing the shaft holes of a screw shaft, reduces the processing time, lowers the processing cost, and achieves an ideal using effect.
Description
Affiliated technical field
The utility model relates to a kind of boring machinery, refers more particularly to a kind of to the used special-purpose machinery of the used stern wheel boring axis hole of boats and ships.
Background technology
On various boats and ships, the stern wheel is the big machinery of using always, it is to guarantee to allow it rotate with hawser in the process of upper and lower hawser, the stability that keeps upper and lower cable operation, therefore, the overall performance of the structure of stern tube shaft is had relatively high expectations, generally require wheel body when operation, the jerk value of self should be greater than ± 2mm, does not lay particular stress on guaranteeing.In order to reach this requirement,, all have higher requirement to stern wheel wheel body integral body and processing and fabricating method thereof.Especially the difficulty of processing to the stern axle hole is bigger relatively, past is after integral body is finished welding, go up large-scale lathe, axle head, wheel body cylindrical, but the machined into expense is excessive, and the duration is long, and waste of material is many, and the head and the tail of the stern tube shaft after processing axis hole axiality becomes excessive, has influence on the assembly quality of bearing and stern tube shaft.
Summary of the invention
It is a kind of simple in structure that the utility model provides in order to address the above problem just, not the efficient stern wheel special boring machine of ideal processing effect.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of efficient stern wheel special boring machine, comprise the feed screw that is provided with on support, sliding table and the support, it is characterized in that, described feed screw is connected with the feeding motor by reduction box, the support upper end is provided with guide rail, and described sliding table top is provided with pin pendulum reductor and boring spindle motor, and wherein pin pendulum reductor is connected with universal joint, the sliding table bottom is provided with the feed nut that matches with feed screw, and through the feed screw drive sliding table integral body is moved along guide rail.
Pin pendulum reductor is connected with the boring axle by universal joint in the utility model, when the boring axle is done rotary work by pin pendulum reductor, drive feed screw by the feeding motor by reduction box, drive sliding table through feed nut again and move, the boring axle is played the effect of feeding along track.In order to reach the desirable effect that feeds, pin pendulum reductor also can be connected frequency modulator with reduction box in the utility model, regulates motor speed by frequency modulator, obtains the input of giving of needs.
Though the utility model is simple in structure, the result of use ideal is controlled in that the stern tube shaft axis hole is added man-hour easily, has shortened machining period, has reduced processing cost, has reached the purpose of this utility model.
Figure of description
Below in conjunction with accompanying drawing the utility model is specified:
Fig. 1 is the utility model structural representation.
Among the figure: 1. support; 2. sliding table; 3. pin is put reductor; 4. boring spindle motor; 5. reduction box; 6. feeding motor; 7. guide rail; 8. feed screw; 9. feed nut; 10. universal joint; 11. boring axle.
The specific embodiment
By accompanying drawing 1 as can be known, the utility model comprises the feed screw 8 that is provided with on support 1, sliding table 2 and the support 1, described feed screw 8 is connected with feeding motor 6 by reduction box 5, be provided with guide rail 7 in support 1 upper end, be provided with pin pendulum reductor 3 and boring spindle motor 4 on described sliding table 2 tops, wherein pin pendulum reductor 3 is connected with universal joint 10, sliding table 2 bottoms are provided with the feed nut 9 that matches with feed screw 8, and through feed screw 8 drives sliding table 2 integral body are moved along guide rail 7.
During work, pin pendulum reductor 3 is connected with boring axle 11 by universal joint 10, and does rotary work by pin pendulum reductor 3.Pin pendulum reductor 3 also can be connected the frequency modulator (not shown) with reduction box 5 in the utility model, regulates motor speed by frequency modulator, obtains the input of giving of needs.
