Abstract
The utility model relates a centre frame for a rotary drum of a large-tonnage hoisting machine. The innovation of the center frame lies in that the centre frame comprises an annular supporting frame and a plurality of tightness mechanisms, wherein the annular supporting frame is arranged on a supporting seat and is formed by connecting two semicircular supports through bolts; the plurality of tightness mechanisms are uniformly distributed on the annular supporting frame and comprise outer sleeves, hollow expansion joints, threaded rods and hand wheels; the outer sleeves are fixed on the annular supporting frame; the hollow expansion joints which are in sliding fit with the outer sleeves are arranged inside the outer sleeves; rollers which are extended out of the outer sleeves are arranged at the top ends of the expansion joints; the threaded rods are arranged in the expansion joints and are in threaded connection with the expansion joints; and the hand wheels are arranged at the tail ends of the threaded rods. The supporting seat is arranged on a guide rail of a lathe to serve as a slider; the annular supporting frame is sheathed in the middle part of the rotary drum to be machined; and the hand wheels are rotated so that the threaded rods drive the hollow expansion joints to move forwards, the roller is propped against the rotary drum to realize the supporting, thereby the machining accuracy of the rotary drum is ensured.
Description
Technical field
The utility model relates to a kind of large-tonnage hoist engine cylinder processing tool, particularly a kind of large-tonnage hoist engine centre of the drum frame.
Background technology
In the man-hour that adds of carrying out large-tonnage hoist engine cylinder, all adopt lathe to carry out the machined of cylindrical, when the clamping cylinder, utilize thimble to fix.Because the volume of cylinder is big, Heavy Weight, thimble can't support preferably, is difficult to guarantee machining accuracy.
Summary of the invention
The technical problem that the utility model will solve provides a kind of large-tonnage hoist engine centre of the drum frame that guarantees machining accuracy.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of large-tonnage hoist engine centre of the drum frame, and its innovative point is: comprise that one is located at the ring holder on the supporting base, this ring holder is formed by connecting through bolt two semi-circular bracket; Several are evenly distributed on the degree of tightness mechanism on the ring holder; Said degree of tightness mechanism comprises outer sleeve, hollow telescopic joint, screw rod and handwheel; Said outer sleeve is fixed on the ring holder, and outer sleeve is built-in with the hollow telescopic joint that is slidingly matched with it, and said telescopic joint top is equipped with the roller that stretches out outer sleeve; Be provided with the screw rod that is threaded with it in the telescopic joint, the end of screw rod is equipped with handwheel.
The advantage of the utility model is: supporting base is installed on the guide rail of lathe, uses as slide block, and ring holder is sleeved on cylinder to be processed middle part; Rotation hand wheel; Make and make the hollow telescopic joint reach of screw drive roller prop up cylinder and realize supporting, thereby guarantee the machining accuracy of cylinder.
Description of drawings
Fig. 1 is the utility model large-tonnage hoist engine centre of the drum shelf structure sketch map.
Fig. 2 is a degree of tightness mechanism structure sketch map in the utility model.
The specific embodiment
As shown in Figure 1, comprise supporting base 1, semicircle bracing frame 2, bolt 3, degree of tightness mechanism 4.
Above-mentioned supporting base 1 is installed on the guide rail of lathe, can be used as the slide block that moves along guide rail.Supporting base 1 is provided with ring holder, and this ring holder is formed by connecting through bolt 3 two semi-circular bracket 2.
On ring holder, be evenly distributed with three degree of tightness mechanisms 4; As shown in Figure 2, this degree of tightness mechanism 4 comprises outer sleeve 41, hollow telescopic joint 42, screw rod 43 and handwheel 44, and outer sleeve 41 is fixed on the ring holder; Outer sleeve 41 is built-in with the hollow telescopic joint 42 that is slidingly matched with it; Telescopic joint 42 tops are equipped with the roller 45 that stretches out outer sleeve 41, are provided with the screw rod 43 that is threaded with it in the telescopic joint 42, and the end of screw rod 43 is equipped with handwheel 44.
During use, ring holder is sleeved on cylinder to be processed middle part, and rotation hand wheel 44 makes screw rod 43 drive hollow telescopic joint 42 reaches, makes roller 45 prop up cylinder and realizes supporting.
