In aforesaid a kind of belt wheel tensioning and quick replacement device, handwheel is set in screw mandrel front end and this handwheel is positioned at outside frame.
In aforesaid a kind of belt wheel tensioning and quick replacement device, it is fixed with screw gear in screw mandrel front portion, the frame of screw mandrel side arranges locking and controls axle, the working end controlling axle in locking is fixedly installed locking control shaft gear, this locking controls shaft gear and engages with screw gear, and the locking controlling axle and frame junction in locking controls to arrange on axleProfile shaft, controls to arrange in the axle frame with frame junction in lockingType hole, shouldProfile shaft withType hole connects and coordinates, and makes device have good self-locking performance.
In aforesaid a kind of belt wheel tensioning and quick replacement device, the two ends controlling to be cased with on axle return spring and this return spring in locking control with locking to hold out against inside shaft gear and inside frame respectively, for controlling the position of axle.
In aforesaid a kind of belt wheel tensioning and quick replacement device, handle is set in the front end of locking control axle and this handle is positioned at outside frame.
Owing to have employed technique scheme, compared with prior art, the present invention is moved on slide rail by screw mandrel drive motor support, thus realizing the belt between motor and machine being carried out stretch-draw pretension or unclamping replacing, simultaneously by allowing screw gear control engaging or separating of shaft gear with locking, realize screw mandrel is controlled, present configuration is simple, easy to operate, there is good auto-lock function, it is possible to the easily tensioning of real belt, and the quick change of belt can be realized between different machines, this device can be directly installed on existing machine simultaneously, economical and practical.

Accompanying drawing 2 is the upward view of the present invention；
Accompanying drawing 3 is that in accompanying drawing 1, locking controls the partial schematic diagram of A amplifier section during axle pull-out；
Accompanying drawing 4 is that in accompanying drawing 1, locking controls the partial schematic diagram of A amplifier section when axle resets.
Detailed description of the invention
Embodiments of the invention: a kind of belt wheel tensioning and quick replacement device, as shown in drawings, including frame 1, at frame 1 top, machine 7 is set, in both sides, frame 1 bottom, guide rail 13 is set, electric machine support 4 across on guide rail 13 and this electric machine support 4 can move along guide rail 13, motor 5 is fixed on electric machine support 4 and connects machine 7 by belt 6, screw mandrel 3 is set immediately below electric machine support 4, electric machine support 4 lower surface arranges electric machine support nut 14, screw mandrel 3 realizes screw mandrel 3 drive motor support 4 move through electric machine support nut 14 and the mode that is threaded connection, these screw mandrel 3 two ends are placed in frame 1, and bearing 2 is set in screw mandrel 3 and frame 1 junction.
Wherein handwheel 9 is set in screw mandrel 3 front end and this handwheel is positioned at outside frame 1, it is fixed with screw gear 8 in screw mandrel 3 front portion, the frame 1 of screw mandrel 3 side arranges locking and controls axle 11, the working end controlling axle 11 in locking is fixedly installed locking control shaft gear 12, this locking controls shaft gear 12 and engages with screw gear 8, and the locking controlling axle 11 and frame 1 junction in locking controls to arrange on axle 11Profile shaft 15, controls to arrange in the axle 11 frame 1 with frame 1 junction in lockingType hole 16, shouldProfile shaft 15 withType hole 16 connects and coordinates, and controls with locking respectively to hold out against inside shaft gear 12 and inside frame 1 locking the two ends controlling to be cased with return spring 10 and this return spring 10 on axle 11, arranges handle 17 in the front end of locking control axle 11 and this handle 17 is positioned at outside frame 1.
The present embodiment is further described by tensioning and quick change principle below by way of this device:
Original state, the locking control gear that the screw gear in lead screw shaft controls with locking on axle keeps engaging under the effect of return spring tension force, and as described in Figure 4, meanwhile, locking controls on axleProfile shaft is just in frameIn type hole, now locking controls axle and loses the degree of freedom of rotation, thus also limit the rotation of lead screw shaft, makes electric machine support be maintained at fixing position.
When belt is carried out tensioning or replacing by needs, as long as pulling locking to control axle by handle, and rotate and make it be stuck in frame, as shown in Figure 3, now two gears are separated from each other, and lead screw shaft obtains the degree of freedom of rotation, if the bracelet on rotating threaded shaft axle, just can change the position of motor, the tensioning of belt can be realized when making motor position away from machine；When making motor position near machine, it is possible to achieve the quick change of belt.
This belt tension and fast replacing device simple in construction, easy to operate, there is good auto-lock function, it is possible to the easily tensioning of real belt, all very practical when a machine and multiple machine, this device can be directly installed on existing machine simultaneously, economical and practical.
The description of such scheme is the invention being understood that for ease of those skilled in the art and using.Embodiment obviously easily can be made various amendment by person skilled in the art.Therefore, the invention is not restricted to above-mentioned solid yardage case, those skilled in the art's the method according to the invention, the improvement made without departing from scope and amendment all should within protection scope of the present invention.
