The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1, the bone sawing machine of present embodiment, comprise frame 1 and be arranged on the saw band tightening in frame 1, described saw band tightening comprises saw band 2, determine belt wheel 3, movable belt pulley 4 and movable belt pulley bearing 5, described frame 1 is provided with rail plate 6, described movable belt pulley bearing 5 is arranged on described rail plate 6 and can slides up and down along rail plate 6, one end that described movable belt pulley bearing 5 matches with rail plate 6 is provided with screwed hole 50, on described rail plate 6, longitudinally offer more than one through hole 60, one hold-down screw 7 is arranged in described screwed hole 50 and one of them through hole 60 is interior that described movable belt pulley bearing 5 and rail plate 6 are fixed, between the bottom of described movable belt pulley bearing 5 and frame 1, be provided with spring assembly 8, in the frame 1 at described movable belt pulley bearing 5 tops, be provided with screw mandrel 9, one end of described screw mandrel 9 leans the top at movable belt pulley bearing 5, the other end is connected with a handwheel 10.
Operation principle of the present utility model is as follows:
When needs tension saw band 2, first the hold-down screw 7 of outwarding winding, movable belt pulley bearing 5 can be slided up and down along rail plate 6, then 9 pairs of movable belt pulley bearings 5 of turn screw mandrel apply a downward pressure downwards, compression spring assembly 8 makes movable belt pulley bearing 5 along rail plate 6 down slidings, thereby the spacing that increases movable belt pulley 4 and determine between belt wheel 3 makes saw band 2 tensionings, after rate of tension meets the requirements, stop turn screw mandrel 9, by hold-down screw 7 aim at screwed holes 50 and now through hole 60 on the other side screw in, movable belt pulley bearing 5 is fixed on rail plate 6 firmly, thereby prevent it from process, rocking and affect machining accuracy, reach sawing process steadily reliable, mechanical oscillation are little, noise is low, effectively guarantee the object of processing stability and machining accuracy.In addition, in adjustment process, can determine the size of tensile force according to the matched position of screwed hole 50 and through hole 60, thereby reach tensile force, stablize controlled object.
When needs relax saw band 2, first the hold-down screw 7 of outwarding winding, movable belt pulley bearing 5 can be slided up and down along rail plate 6, then turn screw mandrel 9 makes progress, the bottom of 8 pairs of movable belt pulley bearings 5 of spring assembly applies a spring restoring force, make movable belt pulley bearing 5 along rail plate 6 upward slidings, thereby the spacing of dwindling movable belt pulley 4 and determining between belt wheel 3 makes saw band 2 lax, after rate of tension meets the requirements, stop turn screw mandrel 9, by hold-down screw 7 aim at screwed holes 50 and now through hole 60 on the other side screw in, movable belt pulley bearing 5 is fixed on rail plate 6 firmly.
In the above-described embodiments, in order to prevent that spring assembly 8, because of the inefficacy saw band 2 that cannot relax, is provided with the second screw mandrel in the frame 1 of described movable belt pulley bearing 5 bottoms, one end of described the second screw mandrel leans in the bottom of movable belt pulley bearing 5, and the other end is connected with a handwheel.When spring assembly 8 lost efficacy, operating personnel can be by regulating the second screw mandrel by movable belt pulley bearing 5 jack-up upwards, thereby the relaxation of realization avoids production process interrupt and cause damage, the follow-up normal operation that can recover bone sawing machine by changing spring assembly 8.
In the above-described embodiments, in order to reduce the wearing and tearing of machine, improve service life, on described rail plate 6, be coated with one deck lubricant, described movable belt pulley bearing 5 is provided with wearing layer with one end that rail plate 6 matches.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
