According to a longitudinal split type clamping manner, the device is easy to debug and has the advantages of simple structure, concise appearance and reliable performance at the same time.
Description
Technical field
The utility model belongs to the auxiliary equipment technical field of metallurgical equipment cold-rolling mill, is specifically related to a kind of split type spindle holder device.
Background technology
When the cold rolled sheet milling train was changed roll, the universal-joint spindle of using as transmission was opened the roll gap action with roll and is moved up and down respectively to the roll change position, at this moment needs a device that universal-joint spindle is fixed, and then the work of extracting out and advancing roller.Will cause relatively difficulty even be stuck in situation in the spindle of roller turnover if the universal-joint spindle fixed position is improper.Traditional spindle holder device upper and lower roll clamp is an overall structure, will cause like this debugging of spindle position suitable after, when adjusting another one spindle position, the position of originally adjusting changes again, and brings great inconvenience to debug process.In addition, the clamp of traditional round arc shape can't be adjusted when the clamped position with needs has deviation up and down, has increased the difficulty of debugging.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of split type spindle holder device, debugging easily, have simultaneously simple in structure, outward appearance succinct, the advantage of dependable performance.
In order to achieve the above object, the technical solution taked of the utility model is:
A kind of split type spindle holder device, comprise bearing 1, oil cylinder 2, L-type pressing plate 3, T-shaped pressing plate 4, cambered surface oil cylinder head 5, slide block 6 and clamping plate 7, two oil cylinders 2 are fixed on up and down on the bearing 1 symmetrically, two other oil cylinder 2 is fixed on up and down on another bearing 1 symmetrically, each oil cylinder 2 is connected with a slide block 6 by cambered surface oil cylinder head 5, four slide blocks 6 are relative in twos, L-type pressing plate 3, T-shaped pressing plate 4 constrains in each slide block 6 on the bearing 1, and slide block 6 can only move along the cylinder rod axis direction, clamping plate 7 are fixed on the slide block 6, and 6 of clamping plate 7 and slide blocks are provided with shim pack.
It is V-structure that described slide block 6 clamps the position.
Because this device adopts two-piece unit formula clamping mode, debugging easily, have simultaneously simple in structure, outward appearance succinctly, the advantage of dependable performance.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
See figures.1.and.2, a kind of split type spindle holder device, comprise bearing 1, oil cylinder 2, L-type pressing plate 3, T-shaped pressing plate 4, cambered surface oil cylinder head 5, slide block 6 and clamping plate 7, two oil cylinders 2 are fixed on up and down on the bearing 1 symmetrically, two other oil cylinder 2 is fixed on up and down on another bearing 1 symmetrically, each oil cylinder 2 is connected with a slide block 6 by cambered surface oil cylinder head 5, four slide blocks 6 are relative in twos, L-type pressing plate 3, T-shaped pressing plate 4 constrains in each slide block 6 on the bearing 1, and slide block 6 can only move along the cylinder rod axis direction, clamping plate 7 are fixed on the slide block 6, and 6 of clamping plate 7 and slide blocks are provided with shim pack.
It is V-structure that described slide block 6 clamps the position.
Operation principle of the present utility model is:
Whole device is fixed on the milling train by two bearings 1, and when universal-joint spindle 8 was in working position, oil cylinder 2 was in retracted mode; During roll change, top roll lifts, lower roll falls to separately on the track, and upper and lower spindle is moved thereupon, is parked in respectively on the roll change position, and at this moment oil cylinder 2 stretches out, and universal-joint spindle 8 is held tightly, and then carried out the roll change action, and oil cylinder 2 was retracted after roll change finished.
When debugging this device, at the inscribed circle center of four clamping plate of clamped condition need to the spindle center superposition.Two oil cylinders in the left side are positional cylinder in four oil cylinders 2, and oil cylinder two oil cylinders in the right are clamping cylinder, and left side oil cylinder piston diameter is larger than the right oil cylinder piston diameter.When debugging, at first to harmonize the clamped position that positional cylinder drives really like this.
The inscribed circle center of four clamping plate and universal-joint spindle 8 centers relatively have following state during debugging: take back in the inscribed circle center, the inscribed circle center takes over, several on the inscribed circle center deviation, under the inscribed circle center deviation and in the comprehensive above-mentioned situation.At this moment just need to adjust pad with several situations above corresponding.
As shown in Figure 3, size Δ c is that pad need to be adjusted thickness, and Δ a is the bias of inscribed circle horizontal direction, and Δ b is the bias of inscribed circle vertical direction.
Among the figure between each size trigonometric function close and to be
Δc=Δa×sinβ
Δc=Δb×cosβ
Like this, when take back in the inscribed circle center, two pads that need simultaneously the left side to be located increase thickness simultaneously; When the inscribed circle center took over, two pads that need simultaneously the left side to be located reduced thickness simultaneously; In the time of on the inscribed circle center deviation, in two pads that need simultaneously the left side to be located, upper square washer increases thickness, and lower square washer reduces thickness; In inscribed circle center deviation lower time, need simultaneously in two pads with location, the left side, and upper square washer reduces thickness, and lower square washer increases thickness, and adjustment amount calculates according to above-mentioned formula.Adjust accordingly clamping the side pad after adjusting location one side position, so that oil cylinder when stretching out, universal-joint spindle 8 can be accurately and firmly is positioned on the roll change position after adjusting again, and roller can pass in and out smoothly.
Because this device adopts two-piece unit formula clamping mode, therefore an other universal-joint spindle 8 also needs to carry out a debugging by above-mentioned steps again, and can not have influence on the good universal-joint spindle of original debugging 8 positions, final so that two universal-joint spindles 8 can both be positioned at correct position when roll change.
