Abstract
The utility model relates to a roll radial-adjusting spindle locking device, relating to a telescopic coupling shaft for rolling mills. A step is processed on the adjusting nut of the roll radial-adjusting spindle; one to three rows are drilled on the step, and each row is provided with a plurality of uniformly distributed screw holes for locking; each row of screw holes are crossedly arranged; locking screws with cylindrical ends are arranged in the screw holes; simultaneously the surface of the spindle cooperated with the adjustment nut is uniformly distributed with two to four grooves axially. The nearest locking screw hole to the groove and the groove are aligned and screwed by locking screws. The utility model can effectively prevent the adjusting nut from loosing.
Description
The utility model relates to the locking device that the scalable coupling spindle of a kind of milling train, particularly roll adjustment connect axle, is applicable to the rolling cycle section profiled bar, as reinforcing bar.
Roll is radially adjusted and is connect axle and be made of guiding mechanism and locking device, and this axle that connects is realized fixing by the self-locking performance of screw thread after adjusting nut and finishing roll and radially adjust.But this fixed form has such problem, and after each adjustment finished adjustment nut location, vibration and rotation because of the roll running hours often made the adjustment nut loosening, connect the axle displacement, so usually influenced the quality of finished steel.
In order to address this problem, the common way of people is to increase by one again to pay nut after adjusting nut, strengthens its locking function.But with regard to connecing axle, be one and give rolling mill drive apparatus that in the continuous rotation of roll, what connect that axle born is a kind of time dependent loading, exists anti-loose problem equally with the transmission of torque of main motor.So, but realize that with this kind method the secure lock of transfer axle is very difficult.
The purpose of this utility model provides a kind of novel locking device, and it can guarantee finished steel in the deviation of its permission, prevents to adjust the loosening of nut effectively.
The purpose of this utility model is achieved in that at roll radially adjusts step of processing on the adjustment nut that connects axle, several equally distributed screws as locking are arranged being drilled with the every row of 1～3 row (best 2 row more than) on the step, and respectively arrange interlaced arrangement between the screw, the lock screw of band cylindrical end is housed in the screw; Simultaneously with adjust connecing that nut matches and be evenly distributed with 2～4 grooves on the surface vertically.After the radially adjustment of at every turn finishing roll, will align from groove nearest locking screw and groove, and the cylindrical end of lock screw screwed in the groove by screw tighten, thereby realize adjusting nut and the positive lock that connects axle.
The center line of adjusting two locking screws that row is adjacent together on the nut is 10～30 degree with adjusting the crossing angle that forms of nut center line, so that when guaranteeing safe and reliable locking, making has minimum locking error on the rolled piece.
Above-mentioned length of bench can be 20～40mm, and the aperture of screw can be 5～12mm, and the degree of depth of groove can be 5～10mm.
The utility model bores 1～3 row's screw because only need at the step of adjusting a 20～40mm of increase on the nut on step, need not to add again and pay nut, so relatively simple for structure; Simultaneously, the starting point of this locking is not the connecing on the axle of transfer motion power, so its abutment shaft intensity and material do not have specific (special) requirements; Because the locking screw can adopt the even interlaced arrangement of many rows, it is very little that per two screw correspondences connect the shaft centre line angle, thereby very little with respect to the scale error of finished product rolled piece, only is 0～0.10mm in addition; Moreover, during locking, require the screw cylindrical end is screwed in the groove that connects axle, so realize adjusting the locking purpose of nut easily.
Below in conjunction with drawings and the specific embodiments the utility model is further described:
Fig. 1 is adjustment nut of the present utility model and the cutaway view that connects axle,
Fig. 2 is adjustment nut of the present utility model and the vertical view that connects axle,
Fig. 3 is the vertical view that connects axle of band groove,
Fig. 4 is the A-A view of Fig. 3.
The utility model locking device comprises and connects axle 2, is arranged on the tooth cover 1 that connects axle 2 two ends and is installed in adjustment nut 3 and the lock nut 4 that connects axle 2 middle parts.In the outside of adjusting nut 3 step 6 is arranged, being drilled with 2 row's screws, 7, two row's screwhole positions on step 6 is interlaced arrangement, and every row's screw evenly distributes, and the corresponding angle of adjusting the nut center line of any two the adjacent screws of every row is 10～30 degree; Connect the axle 2 surfaces be evenly distributed with 4 grooves 8 vertically; Cylindrical end lock screw 5 is housed in each screw, will aligns with it from the nearest screw of groove 87, the cylindrical end of screw 5 is screwed in groove by this screw tighten then, the screw 5 among Fig. 1 is in latched position.
Operating process of the present utility model is: when the adjustment roll connects shaft position, at first unclamp lock screw 5, rotation is adjusted nut 3 to adjust, after adjustment finishes, select apart from the nearest screw of axle 2 upper grooves, make itself and groove 8 align and tighten, screw 5 forms contract cards with connecing axle 2 at this moment, thereby realizes the locking of adjustment nut.
Claims (3)
1. a roll is radially adjusted and is connect shaft lock device, comprise scalable or can radially adjust connect axle, adjust nut, lock nut, axle sleeve, it is characterized in that radially adjusting the adjustment nut (3) that connects axle (2) and go up step 6 of processing) at said roll, on step (6), be drilled with the every row of 1～3 row and have several equally distributed screws (7) as locking, and respectively arrange interlaced arrangement between the screw, the lock screw of band cylindrical end is housed in the screw (7), simultaneously with adjust connecing that nut (3) matches and be evenly distributed with 2～4 grooves (8) on the surface vertically, locking screw and the groove (8) nearest from groove align, and the cylindrical end of lock screw is screwed in the groove (8) by this screw and tightens.
