[0037] 当触发器162按下时,马达120将通过电机轴122带动行星齿轮系内的行星轮、行星架等旋转。 [0037] When the trigger 162 is pressed, the motor 120 is rotated in the planetary gear train of the planetary gear, a planetary carrier shaft 122 by a motor and the like. 最后由第三行星架133将运动输出出去。 Finally, the third planet carrier 133 will move output out. 第三行星架133相对与其通过花键齿148a配合的转接盘148转过一定角度,第三行星架133上的支脚133a将随着第三行星架133转过一定角度。 The third carrier 133 relative thereto by spline teeth 148a mating adapter plate 148 is rotated a certain angle, the leg 133a on the third planetary carrier 133 as the third planet carrier 133 is rotated a certain angle. 其中,当支脚133a转动一定角度后,其将抵靠在滚柱147上。 Wherein, when the angle the legs 133a, which abuts against the roller 147. 由于滚柱147从固定盘143和转接盘148之间的空隙形成的锲面的小端向大端运动,所以滚柱147能被第三行星架133的支脚133a推动,从而跟随第三行星架133转动,直至第三行星架133的中心孔上的凹槽与转接盘148上的花键齿148a相抵靠(可参考图4),这时第三行星架133将带动转接盘148 -起转动。 Due to the small end of the wedge surface 147 is formed from a roller gap between the fixed plate 148 and adapter plate 143 to the movement of the big end, so that the roller 147 can be a third carrier 133 of the leg 133a driven so as to follow the third planetary frame 133 is rotated until the third carrier spline teeth 148a abut against (refer to FIG. 4) on the central hole 133 of the groove 148 and the adapter plate, the third carrier 133 at this time will drive the adapter plate 148 - starting rotation. 转接盘148将进一步带动主轴140旋转。 Adapter plate 148 will further drive shaft 140 is rotated. 最后由主轴140带动夹头150旋转。 Finally, driven by the rotation of the spindle 140 chucks 150.

[0038] 此处定义该钻类工具100正常工作时夹头150的旋转方向为正方向,夹头150沿着正方向的逆方向旋转时的方向为反方向。 [0038] When the drill is defined herein class 100 work tool rotational direction as the positive direction collet 150, collet 150 rotates the direction along the positive direction is a reverse direction in the opposite direction. 当触发器162松开时,该钻类工具100将不再输出旋转运动。 When the trigger 162 released, the drill tool 100 class, no more rotational movement. 此时如果夹头150沿着反方向旋转一定的角度,主轴140也将随着夹头150旋转一定的角度。 At this time, if the cartridge 150 is rotated a certain angle in the opposite direction, the spindle 140 with the collet 150 is rotated a certain angle. 固定在主轴140上的转接盘148也将随着主轴140产生相应的旋转。 Adapter plate 148 is fixed on the spindle 140 will also have a corresponding rotation with the spindle 140. 此时的滚柱147将向该钻类工具100正常工作时的运动方向的反方向运动。 Movement in the opposite direction when the moving direction of the roller 147 at this time will be the class of the drill tool 100 to work. 由于滚柱147从固定盘143和转接盘148之间的空隙形成的锲面的大端向小端运动,固定盘143、转接盘148 和滚柱147之间将会被挤紧,从而达到相互间无运动产生。 Because of the large end face of roller 147 forming wedge from the gap between the fixed plate 148 and adapter plate 143 to the small end of the movement, the fixed plate 143, the adapter plate between the rollers 148 and 147 will be squeezed tight, so that achieved without mutual movement generated. 由于固定盘143是固定在机壳110上,主轴140将不能再继续沿着此方向转动,即主轴140进行了自动锁定,同时转接盘148也将不能将旋转运动传递给第三行星架133。 Since the fixed plate 143 is fixed to the casing 110, the spindle 140 will not continue to rotate in this direction, i.e., the automatic spindle lock 140, while adapter plate 148 will not be able to transmit a rotational movement to the third planetary carrier 133 . 由于自动锁定结构的设置,操作者可以选择手动旋转,这样当夹头150上安装相应的螺丝刀进行拧螺丝时可以进行手动操作。 Since the automatic locking structure is provided, the operator can select manually rotated, so that when the cartridge 150 is mounted on a respective screwdriver can be manually screwing operation. 尤其适用于当该钻类工具100将螺丝拧至基本到位的情况时,可以选择关掉该钻类工具100,进行手动操作。 Particularly suitable when the drilling tool 100 to the class to the basic screw in place, the class may be selected to turn off the drill tool 100, manual operation. 这样可以避免该钻类工具1〇〇采用电动拧螺丝出现过拧而导致螺丝滑牙。 This avoids the use of an electric drill type tool 1〇〇 appeared screwing the screw threaded leading to slip teeth.

[0039] 请参考图2,该钻类工具100还包括限制前轴承142沿主轴140滑动的限位圈145。 [0039] Please refer to FIG 2, the drill tool 100 further comprises a class restriction 142 in the spindle bearing before the stopper rings 145,140 slides. 主轴140上设有限位槽149,限位圈145固定于限位槽149中。 Limiting groove 140 is provided on the spindle 149, the stopper 145 is fixed to the stopper ring groove 149. 这样,当将前轴承142固定在主轴140上时,限位圈145与限位槽149相配合就可以防止前轴承142沿着主轴滑动。 Thus, when the front bearing 142 is fixed on the spindle 140, the stopper ring 145 engaged with the stopper grooves 149 prevent the front bearing 142 can be slid along the major axis.

[0040] 该钻类工具100将后轴承144部分架空在第三行星架133上部分支撑在支撑圈146,第三行星架133通过转接盘148间接的支撑在主轴140上的,支撑圈146直接支撑在主轴140。 [0040] The drilling tool 100 class rear bearing portion of the trolley 144 on the third carrier 133 supported on a support ring portion 146, the third carrier 133 is supported by the indirect transfer tray 148 on the spindle 140, the support ring 146 the spindle 140 is directly supported. 相对于常用的钻类工具分别将前轴承142和后轴承144均支撑在主轴140上的方式,该钻类工具100可以省去后轴承144与第三行星架133相重叠的那部分长度,从而缩短该钻类工具100的长度。 With respect to the commonly used drilling tool class 142, respectively, of the front bearing and the rear bearing 144 are supported manner on the spindle 140, the tool type drill 100 may be omitted after the third bearing 144 and the carrier 133 that overlaps part of the length, so that the shortened length of the tool 100 to drill class. 另外,后轴承144的位置向马达120方向移动,这样该钻类工具100可以在保证主轴140旋转时不剧烈晃动的情况下缩短主轴140的长度,从而缩短该钻类工具100的长度。 Further, the bearing 144 moves the position of the direction of the motor 120, so that the drill tool class can shorten the length of the spindle 100 in the case 140 is not shaken vigorously to ensure the rotation of the spindle 140, thereby shortening the length of the drill tool 100 class. 因此,该钻类工具200具有体积较小的优点。 Thus, the drilling tool 200 having a smaller type size advantages.

[0041] 上述钻类工具将后轴承一部分支撑在支撑圈上,另一部分架空在其它部件上,并且将后轴承的位置向马达方向移动,相对于常用的钻类工具分别将前轴承和后轴承全部支撑在主轴上的方式,该钻类工具可以省去后轴承与其它部件相重叠的那部分长度以及缩短主轴的长度,从而缩短该钻类工具的长度,使该钻类工具具有体积较小的优点。 [0041] The drill-based tool to the rear bearing support portion, another portion of the trolley, and the rear bearing moves the position of the motor direction in the other member on a support ring, with respect to the commonly used drilling Tools are front and rear bearings all supporting manner on the shaft, the bearing may be omitted after the tool type drill with the other member overlapping length is shortened and the length of that portion of the main shaft, thereby shortening the length of the drill type tool, so that the drilling tool has a smaller volume-based The advantages.
