Abstract
The utility model provides a disc type spring locking device, which has low manufacturing cost and stable working performance. The disc type spring locking device comprises a fixing seat (1), a cylinder fastener (2), an end cap fastener (3), an end cap (4), a plurality of disc type springs (5), a piston (6) with an inclined surface, a cylinder (7) and a sealing ring (8) and is characterized in that the cylinder fastener (2) is fixed on the fixing seat (1), the upper side and the lower side of the end cap (4) are respectively provided with a row of disc type springs (5), and the disc type springs (5) on the upper side are connected with the piston (6) with the inclined surface. The disc type spring locking device has a simple structure and lower cost and can be easily manufactured. The locking purpose needs to be achieved only depending on elastic forces produced by the disc type springs (5), and no additional components are needed. Since the main working part of the disc type spring locking device adopts a mechanical structure, the disc type spring locking device has high reliability and can be easily maintained.
Description
Technical field
The utility model relates to the locking device of using on a kind of bar mill, particularly a kind of disk spring locking device.
Background technology
Bar mill can have the trend of tumbling under the effect of tilting moment in the operation of rolling.Because the roll line of production line of bar is changeless; Have some passes side by side on the roll of bar mill simultaneously; So for live pass can be alignd with roll line; Require the bar mill can be along axially the moving of roll, the device of therefore resisting tilting moment must have the characteristic that not only can firmly lock but also can be easy to open.The locking device of current widespread usage is a hydraulic locking apparatus, and when oil-in I led to hydraulic oil, the hydraulic cylinder shaft moved to the indentation direction, reaches the purpose of opening thereby shaft inclined-plane A is disengaged with the part that is locked; When the logical hydraulic oil of oil-in II, the hydraulic cylinder shaft moves to stretching out direction, thereby shaft inclined-plane A is contacted with the part that is locked being used for producing a certain size vertical component, and then the balance tilting moment, reaches the purpose of locking.The locking duty of locking device is a normality.The hydraulic cylinder of existing hydraulic locking apparatus belongs to precision part, and manufacturing cost is high; When hydraulic locking apparatus is in locking during duty, need remain certain working pressure with hydraulic oil in the cavity that oil-in II is communicated with, this just need realize through the mode of increase hydraulic control one-way valve, has increased input; There is the possibility of seepage in hydraulic system, safeguards and gets up to have inconvenience more.
Summary of the invention
According to above technical problem; The utility model provides the disk spring locking device of a kind of low cost of manufacture, stable work in work; Piston (6), cylinder body (7), sealing ring (8) by holder (1), cylinder body securing member (2), end cap securing member (3), end cap (4), disk spring (5), band inclined-plane are formed; It is characterized in that the cylinder body securing member is fixed on the holder, end cap both sides up and down respectively has row's butterfly spring, and the butterfly spring of upside is connected with the piston on band inclined-plane.
The beneficial effect of the utility model is: the utility model substitutes hydraulic locking apparatus with the disk spring locking device; Said disk spring locking device is consistent with hydraulic locking apparatus on operation principle; Be to realize that through the shaft on rotating band inclined-plane is flexible the power that when locking state, promotes shaft is that disk spring provides, and is simple in structure; Be easy to processing and manufacturing, cost is lower; When the disk spring locking device will reach the locking purpose, only lean on the elastic force that disk spring produced to accomplish, need not extra element input, the main working portion of disk spring locking device is a frame for movement, reliability is high, is easy to safeguard.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
According to shown in Figure 1, the utility model is further specified:
Cylinder body (7) is fixed on the holder (1) through cylinder body securing member (2); Cylinder interior is equipped with disk spring (5) between the piston (6) of being with the inclined-plane and end cap (4); End cap (4) is fixed on the cylinder body (7) through end cap securing member (3), has sealing ring (8) to prevent the hydraulic fluid seepage between the piston (6) on cylinder body (7) and band inclined-plane.Because disk spring (5) always is in compressive state between the piston (6) of being with the inclined-plane and end cap (4); So disk spring (5) always gives (6) one in piston to the power of stretching out direction; Thereby the inclined-plane B on the piston (6) of being with the inclined-plane is contacted with the part that is locked; To be used for producing a certain size vertical component, come the balance tilting moment, reach the purpose of locking.When oil-in led to hydraulic oil, the piston (6) on band inclined-plane moved to the direction of indentation under the effect of oil pressure, thereby made the inclined-plane B and the part disengaging that is locked on the piston (6) of being with the inclined-plane, and reached the purpose of opening.
Claims (1)
1. disk spring locking device; Piston (6), cylinder body (7), sealing ring (8) by holder (1), cylinder body securing member (2), end cap securing member (3), end cap (4), disk spring (5), band inclined-plane are formed; It is characterized in that cylinder body securing member (2) is fixed on the holder (1); End cap (4) both sides up and down respectively has row's butterfly spring (5), and the butterfly spring of upside (5) is connected with the piston (6) on band inclined-plane.
