Description
Technical field
The present invention relates to a kind of floating type retaining mechanism, the stepless locking mechanism of particularly a kind of locking when being applicable to exist part tolerance or overproof or thicker side plate.
Background technology
Common floating type retaining mechanism comprises lock shaft, friction plate, movable pulley, spline pin, locking wrench, reel cage side plate and bracket side plate, lock shaft is driven to move by the rotation of locking wrench, rely on friction plate by the arc board clamping on reel cage, thus realize the floating stepless locking on height direction.
Traditional retaining mechanism is, by lock shaft, the side plate of reel cage is drawn distortion, thus makes reel cage side plate be close to bracket, realizes locking thus.The weak point of this locking mode is: if reel cage side plate is thicker, then deflection will diminish relatively; Or, reel cage side plate, bracket side plate due in process because of tolerance reason, the gap between reel cage side plate with bracket side plate will be caused mutually far short of what is expected relative to Theoretical Design value, therefore when locking, even locking wrench can not rotate again, but because of gap between the two, it is unreliable still to cause locking or to lock.
Summary of the invention
The present invention is just in order to the above-mentioned deficiency solving prior art proposes.The object of the present invention is to provide a kind of floating type retaining mechanism, locking when it is applicable to exist part tolerance or overproof or thicker side plate.
According to a first aspect of the invention, floating type retaining mechanism, comprise: lock shaft (1), a pair friction plate (2), reel cage side plate (3), movable pulley (4), bracket side plate (6) and locking wrench (7), lock shaft (1) is successively through friction plate (2), reel cage side plate (3), friction plate (2), movable pulley (4) and bracket side plate (6), and locking wrench (7) is fixed on the outer end of lock shaft (1); Wherein, for being threaded between movable pulley (4) with lock shaft (1), make when rotation lock mandrel (1), movable pulley (4) is fed along the axis of lock shaft (1) by the engagement of screw thread, thus compressing friction plate (2), make a pair friction plate (2) clamping reel cage side plate (3).
According to a second aspect of the invention, in the floating type retaining mechanism of a first aspect of the present invention, spline pin (5) is fixed on bracket side plate (6), in movable pulley (4), arrange spline hole (41), spline pin (5) inserts in spline hole (41).
According to a third aspect of the invention we, in the floating type retaining mechanism of a first aspect of the present invention, the outer end of lock shaft (1) is regular hexagon shape, in locking wrench (7), there are two regular hexagon shapes mutually superposed, the outer end of lock shaft (1) is coordinated with multi-angle with locking wrench (7).
The present invention locks reel cage side plate by the relative motion between lock shaft and movable pulley, on business the locking that causes of poor reason is unreliable can to compensate part, greatly can reduce again the requirement of the machining accuracy to part, and the locking in thicker reel cage side plate situation can be solved.In addition, due to the multi-angle combination between lock shaft and locking wrench, for operator provides better operating experience.

Detailed description of the invention
Below, will by reference to the accompanying drawings, floating type retaining mechanism of the present invention is described in detail.
Figure 1A is the structural representation under floating type retaining mechanism of the present invention is in locking state.As shown in Figure 1A, along the axis of lock shaft (1), floating type retaining mechanism of the present invention comprises successively: lock shaft (1), friction plate (2), reel cage side plate (3), another friction plate (2), movable pulley (4), spline pin (5), bracket side plate (6) and locking wrench (7).A pair friction plate (2) is arranged on the both sides of reel cage side plate (3) respectively.Spline pin (5) is arranged on bracket side plate (6).For being threaded between movable pulley (4) with lock shaft (1), make when rotation lock mandrel (1), movable pulley (4) is fed along the axis of lock shaft (1) by the engagement of screw thread, under spline pin (5) spline effect, compressing friction plate (2) moves axially, and makes a pair friction plate (2) clamping reel cage side plate (3).
Lock shaft (1) is successively through friction plate (2), reel cage side plate (3), friction plate (2), movable pulley (4) and bracket side plate (6).In addition, as shown in figs.3 a and 3b, movable pulley (4) is provided with spline hole 41 (being illustrated as two), spline hole 41 is inserted in spline pin (5), for movable pulley (4) along lock shaft (1) movement during, movable pulley (4) is led and spline.
As shown in Figure 2 A, lock shaft (1) is roughly T section.As shown in Fig. 2 A to 3B, for being threaded between movable pulley (4) with lock shaft (1), thus make when rotation lock mandrel (1), movable pulley (4) is fed along the axis of lock shaft (1) by the engagement of screw thread.As shown in Figure 1A, when movable pulley (4) is along the axis of lock shaft (1), towards being provided with the direction of reel cage side plate (3) (in figure ia, for left side) mobile time, will near and finally oppress friction plate (2), thus realize locking reel cage side plate (3) object.Otherwise, when movable pulley (4) is along the axis of lock shaft (1), towards being provided with the direction of locking wrench (7) (in figure ia, for right side) mobile time, by the compression of release to friction plate (2), thus unclamp reel cage side plate (3).
The operation of floating type retaining mechanism of the present invention is as follows: operator rotate be fixedly installed in lock shaft (1) one end on (as shown in Figure 1A, the other end relative with that one end being provided with a pair friction plate (2) and reel cage side plate (3) of lock shaft (1), the i.e. miner diameter end of the lock shaft (1) in T-shaped cross section) locking wrench (7), lock shaft (1) will be driven to rotate.The rotation of lock shaft (1) causes movable pulley (4) along lock shaft (1), relative movement to occur relative to reel cage side plate (3) by the engagement of screw thread, thus compressing friction plate (2), make a pair friction plate (2) clamping reel cage side plate (3).Like this, the locking of reel cage side plate (3) relative to bracket side plate (6) is just achieved.
Below, the fit system of locking wrench (7) and lock shaft (1) will be described.
As shown in Figure 2 B, the outer end of lock shaft (1) is regular hexagon shape.As shown in Figure 4 B, inner at locking wrench (7), there are two regular hexagons mutually superposed.As shown in Figure 1B, the regular hexagon that locking wrench (7) is inner can be nested in the outer end of the lock shaft (1) capable in positive hexagon.After reel cage side plate (3) is in locking state, the multi-angle inner with locking wrench (7) by lock shaft (1) outer end coordinates, locking wrench (7) is arranged on the convenient desired angle handled, to provide operation convenient to operator.
Floating type retaining mechanism of the present invention utilizes simple structure, by arranging a pair friction plate in the both sides of reel cage side plate, and movable pulley is subjected to displacement along lock shaft by the engagement of screw thread, thus compressing friction plate, achieve the reliable locking of reel cage side plate relative to bracket side plate.
Above, describe the present invention with reference to detailed description of the invention.But it will be understood by those skilled in the art that in the scope not deviating from spirit of the present invention, various improvement can be made to form of the present invention and details, and not depart from protection scope of the present invention.Such as, two overlapped regular hexagon shapes also can be set in the outer end of lock shaft (1), and a regular hexagon is set in locking wrench (7) inside, and make the two cooperatively interact.
