Technical field
The utility model is related to a kind of cohesion device, and in particular to a kind of hot finisher main shaft cohesion device.
Background technology
Main transmission equipment is one of key equipment of hot finisher unit, and main transmission equipment is typically by motor, main
Joint, main gear reducer, herringbone gear, universal-joint spindle etc. reach the purpose for driving roll.After rolling a period of time, working roller abrasion
Need to be changed, and with the raising of hot finisher high speed and automaticity, work roll changing number of times is also increasingly frequent,
Thus require that roll changing time is more short better.Further, since the roll centre absolute altitude of milling train differs with the absolute altitude of herringbone gear shaft
Cause, upper and lower two transmission connecting shafts of milling train are both needed to incline an angle, size and roll gap opening of this angle with roll dressing amount
Change the need for degree, thus transmission main shaft just must use universal-joint spindle, universal-joint spindle can swing certain angle so as to
Meet the requirement of working roll change in location, the position of universal-joint spindle does not know, therefore it is universal to realize that fast roll changing must just make
Spindle is in fixed roll change position.It is such but conventional operation roller changing rig is generally telescopic and C-shaped hook formula changing rig
Changing rig equipment is simple, small investment, easy to operate, but device is difficult to meet fixed needs, and roll change position is inaccurate, causes to change
The roller time is long, seriously reduces production efficiency.
Patent floating type axle head enclasping device (application number：200820030223.2) disclose one kind and realize that Hot Rolling Mill is changed
The floating type axle head enclasping device of roller, sets vertical guide rail on the transmission side window of the rolling mill body left and right sides, and guide rail is provided with mark
Chi, then be installed on part is held tightly on vertical guide rail, the position specified by scale, part is held tightly by spindle nose by Driven by Hydraulic Cylinder
Hold tightly, the cohesion device can realize that new roller shaft head is smoothly docked with universal-joint spindle, but operation is more complicated, and automaticity is not
It is high.
Therefore it is badly in need of a kind of fixing intensity of offer high, makes working roll replacing construction short, accurate, safety, high degree of automation,
Mitigate the hot finisher main shaft cohesion device of operative employee's labour intensity.
Utility model content
The purpose of this utility model is directed to existing cohesion device and fixes loosely, causes that roll change is inaccurate, time-consuming, automatic
Change the shortcoming of low degree, there is provided a kind of fixing intensity is high, makes working roll replacing construction short, accurate, safety, high degree of automation,
Mitigate the hot finisher main shaft cohesion device of operative employee's labour intensity.
The utility model provides following technical scheme：
Hot finisher main shaft cohesion device, including bearing, the bearing are connected with one end of hydraulic cylinder, the hydraulic cylinder
The other end be connected with one end of swinging support arm, the other end of the swinging support arm is provided with peace in axle sleeve, the axle sleeve
Equipped with the first bearing pin, the swinging support arm is connected by the axle sleeve and first bearing pin with the bearing, and described
One bearing pin can be rotated in the axle sleeve, so as to realize the holding of the swinging support arm and open, the swinging support arm
Liner plate is additionally provided with the one end connected with the hydraulic cylinder.
Preferably, the bearing is formed by the second bearing pin with the hydraulic cylinder and is hinged.
Preferably, the hydraulic cylinder is formed by the 3rd bearing pin with the swinging support arm and is hinged.
Preferably, the liner plate is located in the opposite of the swinging support arm with the 3rd bearing pin, and the liner plate leads to
Cross screw to be fixed on the swinging support arm, the liner plate acts on universal-joint spindle.
Preferably, the working face of the liner plate is in arcuation, and arc structure can be such that liner plate is fully contacted with universal-joint spindle, institute
State working face and be provided with friction groove, the frictional force between liner plate and universal-joint spindle can be increased, prevent in the course of work liner plate with
There is relative displacement in universal-joint spindle, increase fixing intensity.
The beneficial effects of the utility model are：The hot finisher main shaft cohesion device fixing intensity that the utility model is provided
Height, makes working roll replacing construction short, and accurate, safety, high degree of automation alleviates the labour intensity of operative employee.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, hot finisher main shaft cohesion device, including bearing 1, bearing 1 and hydraulic cylinder 2
One end is connected, and the other end of hydraulic cylinder 2 is connected with one end of swinging support arm 3, and the other end of swinging support arm 3 is provided with axle sleeve
8, the first bearing pin 5 is installed in axle sleeve 8, the first bearing pin 5 can be rotated in axle sleeve 8, and swinging support arm 3 is by axle sleeve 8 and the
One bearing pin 5 is connected with bearing 1, and liner plate 4 is additionally provided with one end that swinging support arm 3 connects with hydraulic cylinder 2.
As shown in Figure 1 and Figure 4, bearing 1 is formed by the second bearing pin 6 with hydraulic cylinder 2 and is hinged.
As shown in Figure 1 and Figure 5, hydraulic cylinder 2 is formed by the 3rd bearing pin 7 with swinging support arm 3 and is hinged.
As shown in figure 1, the bearing pin 7 of liner plate 4 and the 3rd is located in the opposite of swinging support arm 3, liner plate 4 is fixed by screw
On swinging support arm 3, liner plate 4 acts on universal-joint spindle 9.
As shown in fig. 6, the working face of liner plate 4 is in arcuation, arc structure can be such that liner plate 4 is fully contacted with universal-joint spindle 9,
