Abstract
The utility model provides a hydraulic locking mechanism for accurately positioning a circle-shear rotating cutter rest, comprising a base, a driving mechanism and a cutter rest which are mutually connected. The hydraulic locking mechanism is characterized in that the cutter rest is arranged on a rotating bottom plate, the driving mechanism is arranged on the base, the rotating bottom plate and a revolving support bearing are fixedly connected and are arranged on the base, an upper guiding sleeve is arranged on the rotating bottom plate and rotates with the rotating bottom plate, a lower guiding sleeve is arranged on the base, abush is arranged into the lower guiding sleeve, a locking head is connected with a hydraulic cylinder which is fixed on the base, and the inner surface of the upper guiding sleeve is in a conical shape and is matched with the locking head. The hydraulic locking mechanism is also characterized in that a chamfer angle of 30 degrees is processed on the head of the upper guiding sleeve, which is matched with the locking head. The utility model has the beneficial effect that the locking mechanism is simple in structure and convenient to regulate, shortens time for fixing the rotating cutter rest and increases the production efficiency.
Description
Technical field:
The utility model relates to rotary shear equipment technical field in the cold-reduced sheet finishing production line, particularly relates to the pinpoint retaining mechanism of circle shear double-pole head rotating knife rest.
Background technology:
Rotary shear equipment technical field in cold-reduced sheet finishing production line, the pinpoint retaining mechanism of swivelling tool-holder are the pinpoint important mechanism of double-pole head rotary frame, and can knife rest accurately locate and lock and directly have influence on the quality of edges of shearing steel plate.201020127361.x the utility model patent specification provides a kind of positioning tie bar and locking nut to come to be circle shear knife rest positioning and locking, this upper and lower shear shank is connected by positioning tie bar, adjusting device I is installed on the positioning tie bar, adjusting device II is installed on the last shear shank.The adjusting device of this utility model is simple in structure, and is flexible to operation, and still, this location locking mechanism also is not suitable for the circle shear of double-pole head rotating frame, at present, also is not applicable to the pinpoint retaining mechanism of double-pole head swivelling tool-holder circle shear.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, easy to adjust, production efficiency is high and be applicable to the pinpoint retaining mechanism of circle shear double-pole head swivelling tool-holder of cold rolling finishing production line.
The scheme that its technical problem that solves the utility model adopts is: the pinpoint hydraulic locking of a kind of circle shear swivelling tool-holder mechanism is provided, comprise interconnective base, driving mechanism, knife rest, it is characterized in that: knife rest is installed on the rotation base plate, driving mechanism is installed on the base, the rotation base plate is fixedlyed connected with slewing bearing, they all are installed in above the base, upper guide bush is installed on the rotation base plate, rotatablely move with the rotation base plate, following guide pin bushing is installed in above the base, and lining is installed in down in the guide pin bushing, locking head is connected with hydraulic cylinder, hydraulic cylinder is fixed on the base, and the upper guide bush inner face is a tapered shape, is complementary with locking head; Its feature also is: the head that upper guide bush and locking head are complementary is processed with 30 ° of chamferings.
The beneficial effects of the utility model are: this circle shear swivelling tool-holder hydraulic locking mechanism structure is simple, easy to adjust, has shortened the fixedly time of swivelling tool-holder, has improved production efficiency.
Description of drawings
Fig. 1 is the pinpoint hydraulic locking of a kind of circle shear swivelling tool-holder of a utility model embodiment mechanism front view.
Fig. 2 is the M position enlarged drawing of Fig. 1.
In the accompanying drawing: 1. rotate base plate; 2. slewing bearing; 3. upper guide bush; 4. descend guide pin bushing; 5. lining; 6. locking head; 7. hydraulic cylinder; 8. base; 9. driving mechanism; 10. knife rest.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.As Fig. 1, the pinpoint hydraulic locking of a kind of circle shear swivelling tool-holder mechanism shown in Figure 2, comprise base 8, driving mechanism 9, knife rest 10, it is characterized in that: knife rest 10 is installed on the rotation base plate 1, driving mechanism 9 is installed on the base 8, rotation base plate 1 is fixedlyed connected with slewing bearing 2, they all are installed in above the base 8, upper guide bush 3 is installed on the rotation base plate 1, rotatablely move with rotation base plate 1, following guide pin bushing 4 is installed in above the base 8, and lining 5 is installed in down in the guide pin bushing 4, locking head 6 is connected with hydraulic cylinder 7, hydraulic cylinder 7 is fixed on the base 8, and upper guide bush 3 inner faces are a tapered shape, are complementary with locking head 6.Operation principle of the present utility model is: when circle shear need be changed cutter head, driving mechanism 9 drives slewing bearing 2 rotations, knife rest on the driven rotary base plate 1 10 rotations simultaneously, the cutter head of working position is rotated to the inoperative position to be overhauled, when rotation base plate 1 by after being installed in sense switch on the base 8 and detecting knife rest and be rotated in place, hydraulic cylinder 7 is being with locking head 6 from reaching in the upper guide bush 3 in the guide pin bushing 4 down, and locking head 6 and upper guide bush 3 inwalls are closely cooperated, and will rotate base plate locking.Upper guide bush 3 heads are processed with 30 ° of chamferings, are convenient to locking head 6 and insert locking smoothly.
