Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1, accompanying drawing 2 pairs of this utility model.
As shown in Figure 1, this moment of torsion is adjustable bone drill, comprise housing 1, be installed on the handle 2 of housing 1 rear end, be installed on the switch 3 on handle 2 and be installed in housing 1 and be connected to the motor 4 of switch 3, also comprise the power transmission shaft 6 being connected to motor 4 output shaft, power transmission shaft 6 along the circumferential direction and axis is provided with some spring leafs 11, housing 1 inwall is provided with some blocks 10 corresponding with spring leaf 11 position, power transmission shaft 6 outboard end is fixed with drill chuck 9, when also comprising torque adjusting device for regulating power transmission shaft 6 to rotate, spring leaf 11 from the amoeboid movement of block 10 curving to block 10 opposite side produce the torque adjusting device of torsion.Clamp drill bit by drill jig 9 during use, after the switch 3 on fixed handle 2, motor 4 rotates, thus drives power transmission shaft 6 to rotate.Because power transmission shaft 6 spring leaf 11 in the process of rotating constantly contacts with block 10, make it occur bending and deformation, could pass through from block 10 after flexural deformation.Owing to regulating suitable moment of torsion by torque adjusting device, from block 10 process after spring leaf 11 flexural deformation, the torsion sum produced when now each spring leaf 11 bends is the moment of torsion that power transmission shaft 6 exports.Can torsion needed for the flexural deformation of regulating spring sheet 11 by torque adjusting device, therefore achieve the object that moment of torsion is determined in the convenient adjustment of same bone drill, facilitate doctor according to different situations rotation torque, save purchase cost.
As shown in Figure 2, torque adjusting device can be following structure, it comprises and is fixed on spline housing 5 in motor 4 rotating shaft and by the end cap 7 of threaded engagement in housing 1 head end, end cap 7 internal fixtion has bearing 8, power transmission shaft 6 is plugged in spline housing 5 through the spline arranged by tail end after bearing 8, power transmission shaft 6 is provided with some slideways, and each spring leaf 11 root is provided with the slide rail 12 corresponding with slideway size, and spring leaf 11 is plugged in slideway by slide rail 12.End cap 7 is backed out from housing 1, afterwards power transmission shaft 6 is extracted out, according to demand, the spring leaf 11 of different-thickness specification is inserted in the slideway of power transmission shaft 6 by slide rail 12.After installing, then power transmission shaft 6 is inserted in spline housing 5, and end cap 7 is tightened onto on housing 1.Thickness difference due to spring leaf 11 will cause its bending force to vary in size, and therefore achieves the object solving torque adjustment according to different torque demand by changing spring leaf 11.
As shown in Figure 3, torque adjusting device also can be following structure, it comprises the rotating ring 15 of rotary setting outside housing 1, is arranged at the some chutes 14 on housing 1 and is positioned at chute 14 and is fixed on the adjustable ring 13 of the annular of rotating ring 15, block 10 slides and is arranged in chute 14, block 10 is wedge structure, upper surface is provided with external screw thread 16, the endoporus of adjustable ring 13 is taper thread hole, the tapering of its tapering and block 10 upper surface matches, and block 10 is screwed in the taper thread hole with adjustable ring 13 by external screw thread 16.By rotating rotating ring 15, adjustable ring 13 can be driven to rotate, adjustable ring 13 rotates through screw drive block 10 and moves along chute 14, because block 10 is wedge structure, therefore its height that it exposes within the case 1 in the process moved horizontally also changes thereupon, and therefore spring leaf 11 changes with the contact area of block 10.By adjustment contact area, achieve the object of the torsion that regulating spring sheet 11 flexural deformation is, therefore achieve the adjustment determining moment of torsion, adjustment structure is simply convenient, improves service efficiency.
