Description
Technical field
The present invention relates to a kind of floating type locking mechanism, particularly the stepless locking mechanism of the locking in a kind of situation that is applicable to exist part tolerance or overproof or thicker side plate.
Background technique
Common floating type locking mechanism comprises lock shaft, friction plate, movable pulley, spline pin, locking wrench, reel cage side plate and carriage side plate, rotation by locking wrench drives lock shaft and moves, rely on friction plate with the arc board clamping on the reel cage, thereby realize the unsteady stepless locking on the height direction.
Traditional locking mechanism is by lock shaft the side plate of reel cage to be drawn distortion, thereby makes the reel cage side plate be close to carriage, realizes thus locking.The deficiency of this locking mode is: if the reel cage side plate is thicker, then amount of deformation will diminish relatively; Perhaps, reel cage side plate, carriage side plate are owing to poor reason on business in course of working, will cause the reel cage side plate mutually far short of what is expected with respect to the Theoretical Design value with the gap between the carriage side plate, therefore in the time of locking, even locking wrench can not rotate again, but because of gap between the two, it is unreliable still can to cause locking or locking.
Summary of the invention
The present invention proposes for the above-mentioned deficiency that solves prior art just.The object of the present invention is to provide a kind of floating type locking mechanism, it is applicable to exist the locking in the situation of part tolerance or overproof or thicker side plate.
According to a first aspect of the invention, floating type locking mechanism, comprise: lock shaft (1), a pair of friction plate (2), reel cage side plate (3), movable pulley (4), carriage side plate (6) and locking wrench (7), lock shaft (1) passes friction plate (2), reel cage side plate (3), friction plate (2), movable pulley (4) and carriage side plate (6) successively, and locking wrench (7) is fixed on the outer end of lock shaft (1); Wherein, between movable pulley (4) and the lock shaft (1) for being threaded, so that when rotation lock mandrel (1), movable pulley (4) is axially feeding along lock shaft (1) by the engagement of screw thread, thereby compressing friction plate (2), so that a pair of friction plate (2) clamps reel cage side plate (3).
According to a second aspect of the invention, in the floating type locking mechanism of a first aspect of the present invention, spline pin (5) is fixed on the carriage side plate (6), and spline hole (41) is set in movable pulley (4), and spline pin (5) inserts in the spline hole (41).
According to a third aspect of the invention we, the outer end of lock shaft (1) is the regular hexagon shape in the floating type locking mechanism of a first aspect of the present invention, two mutually regular hexagon shapes of stack are arranged, so that the outer end of lock shaft (1) cooperates with multi-angle with locking wrench (7) in locking wrench (7).
The present invention locks the reel cage side plate by the relative movement between lock shaft and the movable pulley, on business the locking that causes of poor reason is unreliable can to compensate part, the requirement to the machining accuracy of part can be greatly reduced again, and the locking in the thicker reel cage side plate situation can be solved.In addition, because the combination of the multi-angle between lock shaft and the locking wrench, for the operator provides better operating experience.

Embodiment
Below, in connection with accompanying drawing, floating type locking mechanism of the present invention is elaborated.
Figure 1A is that floating type locking mechanism of the present invention is in the structural representation under the locking state.Shown in Figure 1A, along lock shaft (1) axially, floating type locking 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), carriage side plate (6) and locking wrench (7).A pair of friction plate (2) is installed in respectively the both sides of reel cage side plate (3).Spline pin (5) is installed on the carriage side plate (6).Between movable pulley (4) and the lock shaft (1) for being threaded, so that when rotation lock mandrel (1), movable pulley (4) is axially feeding along lock shaft (1) by the engagement of screw thread, under spline pin (5) spline effect, compressing friction plate (2) moves axially, so that a pair of friction plate (2) clamps reel cage side plate (3).
Lock shaft (1) passes friction plate (2), reel cage side plate (3), friction plate (2), movable pulley (4) and carriage side plate (6) successively.In addition, shown in Fig. 3 A and 3B, be provided with spline hole 41 (being illustrated as two) at movable pulley (4), insert in the spline pin (5) in spline hole 41, be used at movable pulley (4) movable pulley (4) being led and spline during the movement of lock shaft (1).
Shown in Fig. 2 A, lock shaft (1) is T section roughly.Shown in Fig. 2 A to 3B, between movable pulley (4) and the lock shaft (1) for being threaded, thereby so that when rotation lock mandrel (1), movable pulley (4) is axially feeding along lock shaft (1) by the engagement of screw thread.Shown in Figure 1A, when movable pulley (4) along lock shaft (1) axially, towards the direction that reel cage side plate (3) is installed (in Figure 1A, be the left side) when moving, will near and final compressing friction plate (2), thereby realize the purpose of locking reel cage side plate (3).Otherwise, when movable pulley (4) along lock shaft (1) axially, when mobile towards the direction that locking wrench (7) are installed (in Figure 1A, being the right side), to discharge the compression to friction plate (2), thereby unclamp reel cage side plate (3).
The operation of floating type locking mechanism of the present invention is as follows: operator rotation is fixedly installed on the end of lock shaft (1) (shown in Figure 1A, the other end relative with that end that a pair of friction plate (2) and reel cage side plate (3) are installed of lock shaft (1), be the miner diameter end of the lock shaft (1) in T-shaped cross section) locking wrench (7), will drive lock shaft (1) and rotate.The rotation of lock shaft (1) causes movable pulley (4) to relatively move along lock shaft (1) with respect to reel cage side plate (3) by the engagement of screw thread, thereby compressing friction plate (2), so that a pair of friction plate (2) clamps reel cage side plate (3).Like this, just realized the locking of reel cage side plate (3) with respect to carriage side plate (6).
Below, the fit system of locking wrench (7) and lock shaft (1) will be described.
Shown in Fig. 2 B, the outer end of lock shaft (1) is the regular hexagon shape.Shown in Fig. 4 B, in locking wrench (7) inside, two mutually regular hexagons of stack are arranged.As shown in Figure 1B, the inner regular hexagon of locking wrench (7) can be nested in the outer end that is the capable lock shaft of positive hexagon (1).After reel cage side plate (3) is in locking state, can pass through lock shaft (1) outer end and cooperate with the multi-angle of locking wrench (7) inside, locking wrench (7) is installed in the convenient desired angle of handling, convenient so that operation to be provided to the operator.
The simple structure of floating type locking mechanism utilization of the present invention, by the both sides at the reel cage side plate a pair of friction plate is set, and so that movable pulley be subjected to displacement along lock shaft by the engagement of screw thread, thereby the compressing friction plate, realized the reliable locking of reel cage side plate with respect to the carriage side plate.
Above, describe the present invention with reference to embodiment.But it will be understood by those skilled in the art that in the scope that does not deviate from spirit of the present invention, can make various improvement to form of the present invention and details, and not depart from protection scope of the present invention.For example, also two overlapped regular hexagon shapes can be set in the outer end of lock shaft (1), and in locking wrench (7) inside a regular hexagon be set, and the two can be cooperatively interacted.
