Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Accompanying drawing 1 is level schematic diagram of the present utility model.
Accompanying drawing 2 is vertical view of the present utility model.
In figure: 1-chuck type mill movement to be flipped, 2-cushion pad, 3-backing plate A, 4-L type resupination framework, 5-bearing, 6-upset base, 7-backing plate B, 8-upset hydraulic cylinder, 9-upset hydraulic cylinder bearing.
Detailed description of the invention
In Fig. 1, a kind of stiff mill turning device, comprises tumble card disc type rolling machine core 1, L-type resupination framework 4, drive unit, bearing 5;
Chuck type mill movement 1 to be flipped is fixed on described L-type resupination framework 4 by pad A3, pad B7, and chuck type mill movement 1 to be flipped has respectively vertical as-rolled condition and horizontal as-rolled condition in orthogonal direction;
Pad A3 is provided with pin-and-hole, and pin-and-hole engages with the alignment pin of the projection at chuck type mill movement to be flipped 1 edge;
L-type resupination framework 4 on-fixed tumble card disc type rolling machine core 1 walls are provided with cushion pad 2;
L-type resupination framework 4 is flexibly connected with bearing 5, and L-type resupination framework 4 is flexibly connected axle for being connected axis with bearing 5;
Drive unit comprises upset hydraulic cylinder 8, upset hydraulic cylinder bearing 9;
The hydraulic cylinder 8 that overturns is fixed on upset hydraulic cylinder bearing 9, and the frame angle of upset hydraulic cylinder 8 clutch ends and L-type resupination framework 4 is hinged, and upset hydraulic cylinder 8 moves back and forth and can drive L-type resupination framework 4 to rotate taking connection axis as axle.
Operation principle: be fixed on the bearing 9 and bearing 5 that are fixed with upset hydraulic cylinder on the upset base 6 on foundation of civil work, when L-type resupination framework 4 is connected with upset supporting base by a major axis, again and upset hinged between hydraulic cylinder 8, under the driving of upset hydraulic cylinder 8, L-type resupination framework 4 can do rotary movement as the center of circle taking the center of bearing 5.As shown in Figure 1, in the time that upset hydraulic cylinder 8 stretches out completely, now turning device just in time makes movement 1 in level; As shown in Figure 2, in the time that upset hydraulic cylinder 8 is retracted completely, now turning device just in time makes movement 1 in vertical state.
When turning device is during in level, backing plate B7 directly holds up movement, and wherein direct the and chuck type mill movement 1 to be flipped of backing plate B7 contacts, and backing plate B7 does corresponding design according to chuck type mill movement 1 understructure feature to be flipped; When turning device is during in vertical state, backing plate A3 directly holds up chuck type mill movement 1 to be flipped, and wherein backing plate A3 does corresponding noncircular pin hole according to chuck type mill movement 1 fore side locating pin structure feature to be flipped, guarantees the steadily of centre of gravity of movement.
The cushion pad 2 of L-type resupination framework 4, can play protection tumble card disc type rolling machine core 1 and avoid the effect of impacting.When turning device by flip horizontal to vertical or by vertical tilting during to level end, always there is center of gravity unstability, hydraulic cylinder 8 loads cause overturning, L-type resupination framework 4 can drop on upset base 6 with certain speed, bring very large impact can to like this tumble card disc type rolling machine core 1, cushion pad 2 can guarantee whole chuck type mill movement 1 steady, safe and reliable complete rotary movement.
Further choosing scheme, cushion pad 2 is provided with irregular projection, can strengthen cushion pad 2 impact resistance in switching process.
Structure in this example is only for for the illustrating and explaining of claim, so that popular reading comprehension should not be considered as the restriction for claim, scope and legal equivalent feature that protection domain of the present utility model should be recorded with claim be as the criterion.
