技术领域 FIELD

[0001] 本发明涉及一种将附件连接到动力驱动器上的工具卡盘,特别涉及一种具有卡爪的工具卡盘,该卡盘能由驱动器传输的动力致动。 [0001] The present invention relates to a method of connecting an accessory to the power tool chuck on the drive, in particular, relates to a tool chuck having jaws, the chuck can be actuated by a power drive transmission.

背景技术 Background technique

[0002] 本申请要求在2005年8月31日提交的第60/712,403号美国临时专利申请的优先权,兹将该申请所公开的全部内容结合到本文中以作参考。 [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 712,403 on August 31, 2005, filed, the entire contents of which is hereby disclosed herein is incorporated herein by reference.

[0003] 将2005年4月19日提交的第60/672,503号('503申请),名称为“T00LCHUCKWITH POWER TAKE OFF AND DEAD SPINDLE FEATURES”的美国申请,结合到本文中以作参考。 [0003] The April 19, 2005, filed No. 60 / 672,503 ( '503 application), entitled "T00LCHUCKWITH POWER TAKE OFF AND DEAD SPINDLE FEATURES" US application, incorporated herein by reference. '503申请通过示例介绍了在不同的模式其中包括卡固模式下可选择地运行的动力驱动器。 '503 application describes by way of example comprises a power drive in different modes in which the retaining selectively operating mode. 在卡固模式下,启动驱动器继而运行(如打开和关闭)工具卡盘。 In the latching mode, then start the drive operation (opening and closing) of the chuck. 卡固过程中,卡盘体和卡爪不旋转。 Trim process, the chuck body and the pawl does not rotate. 由于使用者不容易受到(或观察到)任何旋转部件的影响,这就称为所谓“静轴”特征。 Since the user is not susceptible to (or observe) any rotating member, characterized in this so-called "dead axle."

[0004] 工具卡盘供有滑动套筒,滑动套筒可被选择地安装(即旋转固定)在动力驱动器的机壳上。 [0004] The tool chuck for a sliding sleeve, the sliding sleeve may be selectively mounted (i.e., rotationally fixed) to the casing of the power drive. 当套筒安装完毕,驱动器启动直到致动工具卡盘。 When the sleeve is installed, the actuator drive starts until the tool chuck. 在一些情况下,套筒可选择地将卡盘体安装在动力驱动器的机壳上。 In some cases, the sleeve selectively mounted on the chuck body housing the power drive. 这里,在卡盘致动过程中,卡盘体和卡爪不发生旋转,从而影响静轴特征。 Here, the chuck actuation process, the chuck body and the pawl does not rotate, thereby affecting the characteristics of static axis.

[0005] 传统的滑动套筒工具卡盘通常认为能提供可以达到的性能。 [0005] The conventional sliding sleeve tool chuck generally believed to provide performance can be achieved. 然而,如果卡盘体是可选择地安装在动力驱动器的机壳上,同时电机向前运转直到卡爪紧固到附件上,那么此时就会导致电机停转。 However, if the chuck body is selectively mounted on the housing power drive, while the motor is running forward until the attachment is fastened to the jaw, then the time will stop motors. 当工具卡盘被驱动至达到完全打开的状态时,电机也有可能停转。 When the tool chuck is driven to its fully open state, the motor may also be stalled. 电机停转有可能毁坏电机,破坏传输和/或造成紧固转矩的不稳定。 Motor stops may damage the motor, transmission damage and / or cause tightening torque instability.

[0006] 为了克服上述缺点作了大量工作。 [0006] In order to overcome the above drawbacks done a lot of work. 例如,动力驱动器可配有电动离合器。 For example, a power driver may be equipped with an electric clutch. 这里,当滑动套筒可选择地与动力驱动器的机壳接合时,电动离合器能将其施加的转矩限制在一个期望的紧固转矩(在卡固启动过程中)范围内。 Here, when the sliding sleeve is selectively engageable with the housing power drive, an electric clutch which can limit the torque applied to a desired tightening torque (at startup trim) range. 或者,通常用在钻孔/驱动模式下以限制施加的转矩的动力驱动器的机械式离合器,也可应用以将施加的转矩限制在一个期望的紧固转矩(在卡固启动过程中)范围内。 Alternatively, commonly used in drill / driving mode clutch mechanically imposed limit power drive torque can be applied to limit the torque applied to a desired tightening torque (at startup trim ) within the range.

[0007] 上面所述的电动和机械式离合器都并非没有缺点。 [0007] The above electric and mechanical clutches are not without disadvantages. 比如,动力驱动器需要配备多重操作速度。 For example, with multiple power drive required operating speed. 如果电子设备不能确定和校正所选的操作速度,那么电子离合器传送的转矩在卡盘启动过程中就会改变。 If the electronic device can determine and correct the selected operating speed, the electronic clutch torque transmitted will change chuck startup. 当动力驱动器的机械式离合器用作卡盘启动过程中限制施加的转矩在一个期望的紧固转矩时,也会出现同样的状况。 When used as a mechanical clutch torque starting power drive chuck during a limitation imposed upon the desired tightening torque, the same situation will appear.

[0029] 例如,工具卡盘50配备有“推进器”式卡爪(图中未示出)。 [0029] For example, the tool chuck 50 is provided with a "pusher" type pawl (not shown). 这里,卡盘驱动轴55的前端设有径向向内面螺纹58。 Here, the front end of the chuck shaft 55 is provided with threads 58 faces radially inwardly. 与'503申请中所述的结构相似,径向向内面螺纹58与卡盘致动螺钉(图中未示出)的径向向外面螺纹相互作用,卡盘致动螺钉可以支撑卡爪。 And the '503 application, the structure is similar to the threaded surface 58 radially inwardly and the chuck actuating screw (not shown) to the outside of the radial threads interacting, the chuck actuating screw may support the jaws. 卡盘驱动轴55的螺纹58与卡盘致动螺钉的螺纹之间的相互作用可以使卡爪相对于卡盘体52沿轴向前进和后退。 The interaction between the chuck shaft 55 of the screw 58 and the chuck actuating screw thread can jaws relative to the chuck body 52 is axially advanced and retracted. 可以看出,卡盘致动螺钉和卡盘体52可以通过卡爪旋转地锁定在一起。 As can be seen, the chuck actuating screw and the chuck body 52 can be locked together by rotation pawl.

[0030] 套筒60和卡盘体52具有配合特征,藉此套筒60和卡盘体52能在轴向相互运动以及旋转锁定在一起。 [0030] The sleeve 60 and the chuck body 52 having a mating feature, whereby the sleeve 60 and the chuck body 52 can be together in mutual axial movement and rotation lock. 例如,套筒60具有向前(forward)花键63 (如图8所示)用于与卡盘体52的花键53相互作用。 For example, the sleeve 60 has a forward (Forward) splines 63 (FIG. 8) for the spline 53 of the chuck body 52 interacts. 套筒60具有向后(rearward)花键66 (如图7所示)用于与卡盘驱动轴55的花键56可选择地接合。 Sleeve 60 having rearwardly (rearward) splines 66 (shown in FIG. 7) for selectively engaging the drive shaft 56 and chuck 55 splines. 套筒60具有套筒凸耳68用于与端盖94的凹穴98可选择地接合。 Sleeve 60 has a sleeve lug 68 to selectively engage the recesses 98 of the end cap 94.

[0031] 动力驱动器包括机壳90。 [0031] The power drive includes a housing 90. 机壳90包括装配在一起的主体92和端盖94。 The housing 90 includes a body 92 and an end cap assembly 94 together. 在可替换实施例中,主体92和端盖94可为一个整体,即一体结构。 In an alternative embodiment, the body 92 and end cap 94 may be integral, i.e. unitary structure. 机壳90可支撑输入轴10、输出轴30和锤击机构70。 The housing 90 may support the input shaft 10, output shaft 30 and the hammer mechanism 70.

[0032] 输入轴10旋转安装在主体92上。 [0032] The input shaft 10 rotatably mounted on body 92. 可以配设轴承2 (如滚针轴承)用以易于输入轴10和主体92之间的相对旋转。 2 may be disposed bearing (e.g. a needle bearing) and the main body 10 for easy relative rotation between the input shaft 92. 输入轴10与动力驱动器传动装置的输出相连接(图中未示出)。 The input shaft 10 and the output gear is connected to a power driver (not shown). 可以适当地应用本领域中众所周知的多种不同的动力驱动器传动装置。 A plurality of different power drive transmission means known in the art may be appropriately applied. 输入轴10的前端包括盲孔12。 The front end of the input shaft 10 includes a blind bore 12. 盲孔12可以容纳输出轴30的一端。 Blind bore 12 may receive end 30 of the output shaft. 输入轴10包括凸缘14。 The input shaft 10 includes a flange 14. 输入轴10的一个轴向向前的面上具有驱动凸耳16(如图2所示)。 An input shaft 10 axially forward surface having a drive lug 16 (FIG. 2). 驱动凸耳16具有逐渐变细斜面的末端(如图8所示)。 Driving lug 16 having a beveled tip tapers (Figure 8).

向。 to.

[0034] 锤击机构70包括旋转棘齿72、旋转固定棘齿74和凸轮环76。 [0034] The hammer 70 includes a rotation ratchet mechanism 72, rotation of the ratchet teeth 74 and the fixed cam ring 76. 如图I所示,旋转棘齿72和输入轴10可为一个整体即一体结构。 As shown in FIG. I, the ratchet teeth 72 and the rotation of the input shaft 10 as a unitary structure that is integral. 在可替换的实施例中,旋转棘齿72和输入轴10为两个可被固定在一起的分离和不同的部件。 In an alternative embodiment, rotation of the ratchet teeth 72 and the input shaft 10 may be secured together two separate and distinct parts. 旋转固定棘齿74相对于机壳90的主体92旋转地固定并可轴向运动。 74 rotationally fixed relative to the ratchet body 92 is rotatably and axially fixed to the housing 90 of the movement. 旋转固定棘轮74具有中心孔,输入轴10可通过该孔延伸。 Rotationally fixed ratchet 74 has a central bore, the input shaft 10 may extend through the aperture. 凸轮环76包括使用者可操作的控制杆或套筒,以可选择地将棘轮72、74接合。 The cam ring 76 includes a user operable lever or sleeve, 72, 74 to selectively engage the ratchet.

[0035] 弹簧6设置在旋转、固定棘轮74和输入轴10的凸缘14之间。 [0035] The spring 6 is disposed between the flange rotation, the ratchet wheel 74 fixed to the input shaft 10 and 14. 弹簧6可影响旋转固定棘轮74轴向向前的运动以及与凸轮环76的操作接合。 Effect of the spring 6 may be fixed to the rotational movement of the ratchet wheel 74 axially forward and the operation ring 76 engages with the cam. 旋转固定棘轮74的轴向向后的运动受到凸轮环76的限制。 Axially rearward movement of the ratchet wheel 74 is stationary by rotating the cam ring 76 is restricted. 弹簧6也会影响输入轴10 (并因此影响可旋转棘轮72)的轴向前向的运动。 Also affect the spring 6 of the input shaft 10 (and therefore affect the rotatable ratchet 72) prior to movement of the axial direction. 输入轴10的轴向前向的运动受到连接部20的限制。 Before the input shaft 10 to the axial movement of the connecting portion 20 is restricted.

[0036] 销8滑动安装在端盖94圆周周围的各个轴向孔上(图中未示出)。 [0036] The pin 8 slidably mounted in the axial bore around the circumference of each end cap 94 (not shown). 销8的前端延伸入端盖94的凹穴98内。 The pin 8 extends into the distal end cap 94 of the pocket 98. [0037] B.操作 [0037] B. Operation

[0038] 工具卡盘50的操作根据以下因素而不同:(I)旋转固定棘轮74的轴向位置;(2)套筒60的轴向位置。 [0038] The operation of the tool chuck 50 is different depending on the following factors: (I) a fixed axial position of the rotation of the ratchet wheel 74; axial position (2) of the sleeve 60. 不同的操作模式包括(但并非局限于)钻孔/驱动模式、锤击模式和卡固模式。 Different modes of operation including (but not limited) drill / driving mode, the hammer mode and a latching mode.

[0039] 图1、2所示为卡盘系统无偏压下的钻孔/驱动模式。 [0039] Figure 1 is a chuck system without drill / driving mode bias. 如图所示,旋转固定棘轮74处于轴向向后的位置(且与旋转棘轮72脱离),因此锤击机构70处于停止状态。 As shown, the ratchet wheel 74 is rotationally fixed in the axial rearward position (and out of engagement with the ratchet wheel 72 rotation), so the hammer mechanism 70 is in a stopped state. 同时,套筒60位于轴向向前位置。 Meanwhile, the sleeve 60 is located axially forward position. 在这种情况下,卡盘驱动轴55的花键56 (如图7所示)与套筒60的后向花键66接合,这样卡盘体52、卡盘驱动轴55和套筒60就能够旋转锁定在一起,并且作为一个单元一起旋转。 In this case, the chuck shaft 55 of the key 56 (FIG. 7) and the rear sleeve 60 engages the spline 66, so that the chuck 52, the chuck 55 and the sleeve 60 on the drive shaft rotatably locked together, and rotate together as a unit. 由于卡盘体52和卡盘驱动轴55旋转锁定在一起,工具卡盘50在操作中就不会松动。 Since the chuck 52 and chuck 55 rotation of the drive shaft are locked together, the tool chuck 50 will not become loose during operation.

[0040] 然后使用者启动驱动器以旋转驱动输入轴10,使其相对于旋转固定棘轮74旋转。 [0040] The user then starts to drive the rotary drive input shaft 10, it is fixed with respect to rotation of the ratchet wheel 74 to rotate. 输入轴10通过驱动凸耳16和从动凸耳26之间的接合来旋转驱动输出轴30。 The input shaft 10 by the driving lug 16 to rotate the output drive and the driven lugs 26 engagement between the shaft 30. 在弹簧6的作用下,驱动凸耳16的逐渐变细斜面超过从动凸耳26的逐渐变细斜面而插入到连接部20内。 Under the action of the spring 6, the driving lug inclined surface 16 tapers over the driven lug is tapered chamfer 26 is inserted into the connector portion 20. 这种状态下,将提供转矩联结,在该转矩联结中,输入轴10的所有转矩传输到输出轴30上。 In this state, the coupling providing a torque, the torque coupling, all the torque of the input shaft 10 is transmitted to the output shaft 30. 输出轴30旋转驱动工具卡盘50。 Output shaft 30 rotationally driving the tool chuck 50.

[0041] 图3、4所示与图1、2所示相似,均为钻孔/驱动模式,不同的是卡盘系统处于偏置状态。 [0041] FIG similar to that shown in FIG. 3 and 4 and 1 and 2 are drill / driving mode, except that the chuck system in a biased state. 比如,当使用者将附件(如钻头)压靠在工件上时,偏压(或者外力)就发生了。 For example, when a user attachment (e.g., a drill) is pressed against the workpiece, a bias (or force) occurs. 如图所示,偏压会克服输出轴30的凸缘34与轴承4之间的弹簧(图中未示出)的影响,在相对于机壳90的轴向向后的方向上移动工具卡盘50 (并因此移动输出轴30和输入轴10)。 Shown, will overcome the bias of the flange 34 of the output shaft 30 and the bearing spring FIG Effect (not shown) between 4, with respect to the axial direction of the housing 90 rearward movement of tool-engaging plate 50 (and thus movement of the output shaft 30 and the input shaft 10).

[0042] 输出轴30 (并因此工具卡盘50)的轴向向后运动受到压靠轴承4的凸缘34的限制。 [0042] The output shaft 30 (and thus the tool chuck 50) by rearward axial movement of the bearing 4 is pressed against the limiting lip 34. 这样,由于偏压所致的组件的轴向向后运动就受到了限制,因此旋转棘轮72保持远离旋转固定棘轮74 (也就是锤击机构70保持停止),并且套筒60保持远离端盖94。 Thus, due to the axial rearward movement of components due to the bias has been limited, so that the rotation of the ratchet 72 is held away from the ratchet wheel 74 rotationally fixed (i.e., holding the hammer mechanism 70 is stopped), and the sleeve 60 is held away from the end cap 94 . 当偏压去除后,组件就会回到图1、2所示的状态。 When the bias is removed, the component will return to the state shown in FIGS.

[0043] 图5、6所示为卡盘系统偏压的锤击模式。 As shown in [0043] Figures 5 and 6 is a bias chuck system hammer mode. 使用者可以操作凸轮环76使旋转固定棘轮74在轴向向前的方向上移动并克服弹簧6的影响以实现锤击模式。 The user can operate the rotation of the cam ring 76 and the fixed ratchet 74 is moved against the influence of the spring 6 to achieve a hammer mode in the forward axial direction. 由于卡盘系统被偏压,输出轴30 (依靠连接部20),在轴向向后的方向上移动输入轴10 (并因此移动旋转棘轮72)和克服弹簧6的影响。 Since the chuck is biased system, the output shaft 30 (by virtue of the connection portion 20) in a direction axially rearward movement of the input shaft 10 (and thus the rotational movement of the ratchet wheel 72) and against the influence of the spring 6. 在这种状态下,旋转固定棘轮74与旋转棘轮72接合。 In this state, the rotation of the fixed ratchet 74 engages the ratchet wheel 72 rotating. 可以理解,当从卡盘系统去除偏压后,弹簧6会使旋转棘轮72 (并且输入轴10和输出轴30)运动到轴向向前的位置,这可使得棘轮72、74脱离。 It will be appreciated, when the bias is removed from the chuck system, the spring 6 causes rotation of the ratchet 72 (and the input shaft 10 and the output shaft 30) to position axially forward, the ratchet wheel 72, which may cause detachment.

[0044] 然后使用者启动驱动器,以旋转驱动输入轴10 (和旋转棘轮72 —起),而输入轴10将相对于旋轮固定棘轮74旋转。 [0044] The user then starts the drive to rotate the drive input shaft 10 (and the rotating ratchet 72-- onwards), the input shaft 10 and the knob 74 is rotated relative to the fixed ratchet wheel. 假如卡盘系统保持偏压,那么棘轮72、74之间的相对旋转就导致输入轴10、输出轴30和工具卡盘50相对于机壳90发生相对移位,从而产生往复的轴向运动。 If the system maintains the chuck bias, then the relative rotation between the ratchet wheel 72 to cause the input shaft 10, output shaft 30 and the tool chuck 50 with respect to the housing 90 occurs relative displacement, thereby producing a reciprocating axial movement. 例如,如图所示,旋转棘轮72和旋转固定棘轮74均具有各自的齿。 For example, as shown in FIG, 72 and the rotatable ratchet rotationally fixed ratchet 74 has a respective tooth. 当旋转棘轮72的齿骑在旋转固定棘轮74的齿之上的时候,旋转棘轮72沿轴向远离旋转固定棘轮、74。 When the rotatable ratchet teeth to ride over the teeth 72 of the ratchet wheel 74 is rotationally fixed when rotating the ratchet wheel 72 in the axial direction away from the ratchet wheel rotationally fixed, 74. 当齿彼此经过时,施加在卡盘系统上的偏压使旋转棘轮72回到如图5、6所示的轴向位置。 When each other through the teeth, the bias applied to the chuck of the rotating ratchet system 72 back to the axial position shown in FIG. 5 and 6. 这样,当驱动器启动后,工具卡盘50将旋转以及轴向往复。 Thus, when the driver is powered up, the tool chuck 50 rotation and axial reciprocating.

[0045] 图7、8所示为卡固模式。 [0045] Figure 7-8 is a latching mode. 仅仅作为示例,动力驱动器可在卡盘系统非偏压时(如图所示)处于卡固模式下操作。 By way of example only, a power driver may (as shown) fastened in the operating mode when the chuck system is unbiased. 旋转固定棘轮74处于轴向向后位置(并且脱离旋转棘轮72),以使锤击机构70停止。 Rotationally fixed ratchet 74 is in the axial rearward position (and rotation from the ratchet wheel 72), so that the hammer mechanism 70 is stopped. 同时,使用者可将套筒60移动至轴向向后位置。 Meanwhile, the user may move the sleeve 60 to the axially rearward position. 在该轴向运动过程中,套筒60的后向花键66与卡盘驱动轴55的花键56脱离(因而卡盘驱动轴55相对于卡盘体52旋转),并且套筒凸耳68能够进入端盖94的凹穴98中(因而套筒60和卡盘体52能够旋转安装在动力驱动器的机壳90上)。 In this axial movement, the rear sleeve 60 splined shaft 56 from the splines 55 of the chuck 66 (and thus the chuck 55 of the drive shaft 52 is rotated relative to the chuck body), and the sleeve lugs 68 the end cap 94 to enter recesses 98 (and thus the sleeve 60 and the chuck 52 is rotatably mounted on the housing of the power drive 90).

[0046] 当套筒凸耳68进入凹穴98时,套筒凸耳68沿轴向向后方向驱动销8 (并因此驱动输入轴10)和克服弹簧6的影响。 [0046] When the sleeve 68 into the lug recesses 98, the lugs 68 of the sleeve 8 the drive pin in the axial rearward direction (and thus drive the input shaft 10) and against the influence of the spring 6. 输出轴30 (并因此连接部20)在凸缘34和轴承4之间的弹簧(图中未示出)的作用下,保持在轴向向前位置。 Output shaft 30 (and therefore the connecting portion 20) at the bearing flange 34 and between the spring 4 (not shown) role in maintaining the axial forward position. 由此,输入轴10的轴向向后移动将导致驱动凸耳16部分地离开连接部20的从动凸耳26,以使驱动凸耳16的逐渐变细斜面能够在圆周方向面对从动凸耳26的逐渐变细斜面(如图8所示)。 Thus, the axial movement of the input shaft 10 rearwardly will cause the lug 16 away from the drive part connected to the driven portion 20 of the lug 26, so that the inclined surface tapering from the drive lug 16 can be driven in a circumferential direction to face lug tapering inclined surface 26 (FIG. 8).

[0047] 使用者可以启动驱动器来旋转驱动输入轴10。 [0047] The user may activate the input drive shaft 10 is rotationally driven. 输入轴10通过驱动凸耳16和从动凸耳26的接合来旋转驱动输出轴30。 The input shaft 10 by engaging the driven lug 16 and the lug 26 of the drive shaft 30 to rotate the drive output. 输出轴30相对于卡盘体52 (通过套筒60旋转安装到机壳90上)旋转驱动卡盘驱动轴55。 Output shaft 30 relative to the chuck body 52 (rotatably mounted to the housing 90 through the sleeve 60) rotationally driven chuck shaft 55. 如'503申请所述,卡盘驱动轴55和卡盘体52之间(并因此卡盘致动螺钉和卡爪)的相对旋转将致动工具卡盘50 (也就是根据动力驱动器的操作方向来打开和/或关闭卡爪)。 The '503 herein, the chuck shaft 55 and the chuck body 52 (and thus the chuck actuating screw and jaw) rotated relative to the chuck actuating tool 50 (i.e. the direction of operation of the power drive according to to open and / or close the jaws). 此外,在卡盘致动期间,卡盘体和卡爪不发生旋转。 In addition, during actuation of the chuck, the chuck body and the pawl does not rotate. 由于使用者不容易受到(或观察到)任何旋转部件的影响,这就称为所谓“静轴”特征。 Since the user is not susceptible to (or observe) any rotating member, characterized in this so-called "dead axle."

[0048] 在卡盘致动过程中,当工具卡盘50没有完全打开或关闭(例如当卡爪仍正在打开或关闭时),输入轴10可通过驱动凸耳16和从动凸耳26之间的相互作用旋转地驱动输出轴30。 [0048] In the chuck actuation process, when the tool chuck 50 is not fully opened or closed (e.g., when the jaws are still being opened or closed), the input shaft 10 by driving the driven lugs 16 and the lugs 26 interaction between the rotationally drive the output shaft 30. 当工具卡盘50完全关闭(有或没有插入的附件)或完全打开时,驱动凸耳16作用到从动凸耳26上的旋转力将加大。 When the tool chuck 50 is fully closed (with or without insertion of the accessory) or fully opened, the drive lugs 16 to effect driven rotation force on the lug 26 will increase. 该旋转力增加到一阈值,在此凸耳16、26的逐渐变细斜面相配合以在轴向向后方向上驱动输入轴10并克服弹簧6的影响,因此驱动凸耳16滑过从动凸耳26的末端。 The rotational force is increased to a threshold, here inclined surface tapering lugs 16, 26 cooperate to drive in the axial direction of the input shaft 10 and rearward against the influence of the spring 6, the drive lugs 16 slides over the follower projection ear tip 26. 在这种情况下,驱动凸耳16和从动凸耳26能够提供一离合特征,用来限制卡盘致动过程中所施加的转矩。 In this case, the drive lugs 16 and the driven lugs 26 can be provided wherein a clutch for limiting the chuck torque applied during actuation.

[0049] 可以理解,在轴向向后的方向上驱动输入轴10所需的旋转力的值受到如凸耳16、26的逐渐变细斜面的倾斜角度和/或弹簧6的弹簧常数的影响。 [0049] It will be appreciated, the value of rotational force required to drive the input 10 in the axial direction of the shaft rearwardly tapered as affected by the lugs 16, 26 and the inclination angle of the inclined surface of fine spring constant and / or spring 6 . 此外,通过适当设计逐渐变细斜面的外形,可使紧固工具卡盘50的转矩阈值小于松开工具卡盘50的转矩阈值,反之亦然。 Further, by appropriate design of the inclined surface tapering shape allows torque threshold fastening tool chuck 50 is smaller than the release torque threshold tool chuck 50, and vice versa.

[0050] 在图9-14所描述的实施例中,图9-14示意性地描述了一示例性而非限制性的工具卡盘150。 [0050] In the embodiment depicted in FIG. 9-14, the Figure 9-14 schematically depicts an exemplary and non-limiting tool chuck 150. 该工具卡盘可应用于以上部分所描述的卡盘系统中。 The tool chuck may be applied to the chuck system described in the above section. 如图9-14所示,工具卡盘150可移动地接收附件105的柄。 As shown in Figure 9-14, the tool chuck 150 may removably receive the handle 105 attachment.

[0051] A.结构 [0051] A. Structure

[0053] 驱动套筒120可以轴向固定到卡盘体152上。 [0053] The drive sleeve 120 may be axially fixed to the chuck body 152. 将轴承107 (如滚珠轴承)放入到驱动套筒120和卡盘体152之间,以利于组件120和152之间的相对旋转。 The bearing 107 (e.g., ball) placed in the drive sleeve 120 and between the chuck body 152, the relative rotation between 120 and 152 facilitate assembly. 轴承107通过(例如)托架连接或它们可以松开。 Bearings 107 (e.g.) or they may be releasably connected to a bracket. 轴承107可以在由卡盘体152和驱动套筒120分别提供的环形凹槽151、121(如图10所示)之间保持。 Bearing 107 may be maintained between the annular grooves 151,121 by the chuck body 152 and the drive sleeve 120 are provided (FIG. 10). 驱动套筒120设有径向向内面螺纹128。 The drive sleeve 120 is provided with a threaded surface 128 radially inwardly. 径向向内面螺纹128与卡盘致动螺钉180的径向向外面螺纹188相互作用。 Radially inwardly threaded surface 128 of the chuck actuating screw 180 to a radially outer thread 188 interacting. 这样,驱动套筒120就可以螺纹连接到卡盘致动螺钉180。 Thus, the drive sleeve 120 can be screwed to the chuck actuating screw 180.

[0054] 弹簧106保持在卡盘体152和衬套110 (牢固连接到输出轴130上)之间。 [0054] The spring 106 held between the chuck body 152 and the bushing 110 (130 securely attached to the output shaft). 弹簧106在轴向后向方向上影响卡盘体152(并因此驱动套筒120)。 Effect of the spring 106 in the axial direction of the chuck body 152 (and thus the drive sleeve 120). 卡盘体152的轴向后向运动受到压靠衬套110的离合表面112的驱动套筒120的离合表面122的限制。 After the chuck body 152 is axially limited by the liner 110 is pressed against the clutch surface of the drive sleeve 112 of the clutch 122 to the surface 120 of the movement.

[0055] 卡盘致动螺钉180包括径向通道186,卡爪101可分别经由这些通道滑动。 [0055] The chuck actuating screw 180 includes a radial channel 186, 101 are provided for sliding the pawl via these channels. 径向通道186将卡盘致动螺钉180旋转固定到卡爪101上。 The radial channels 186 of the chuck actuating screw 180 rotatably secured to the pawl 101. 螺纹128和188之间的相互作用引起卡盘致动螺钉180相对于卡盘体152在轴向上前进或后退。 The interaction between threads 128 and 188 cause the chuck actuating screw 180 relative to the chuck body 152 forward or backward in the axial direction.

[0056] 卡盘体152的前端牢固地支撑凸头部140和爪固定器145。 [0056] The front end of the chuck body 152 is firmly supported the nosecone 140 and the claw holder 145. 凸头部140为锥形,并围绕爪固定器145。 Projection head 140 is tapered and surrounds fixed jaw 145. 爪固定器145具有倾斜槽147 (如图10所示),卡爪101可以分别经过这些槽滑动。 A fixed jaw 145 having an inclined groove 147 (Figure 10), pawl 101 can slide through the slots, respectively. 卡爪101具有能沿着爪固定器145的逐渐变细外轮廓滑动的突片103。 The pawl having a tab 101 to slide along the tapered outer profile of the fixed jaw 145 103. 凸头部140的径向向内的表面压靠突片103的径向向外表面,以防止卡爪101从爪固定器145的槽147上移开。 Projecting radially inwardly facing surface of the head 140 against the tab 103 radially outward surface, in order to prevent pawl 101 away from the jaw of the fixed slot 147,145. 可以理解,卡盘致动螺钉180、凸头部140和爪固定器145能够通过卡爪101旋转锁定在一起。 It will be appreciated, the chuck actuating screw 180, the head 140 and projecting jaw holder 145 can be locked together by a pawl 101 rotates.

[0057] 套筒160可以通过配合特征安装在卡盘体152上,通过配合特征组件152、160可以相互轴向运动并且旋转锁定在一起。 [0057] The sleeve 160 may be mounted by mating feature 152 on the chuck body, characterized by blending the components 152,160 axially movable and rotation locked together mutually. 例如,套筒160具有前向花键163 (如图10所示),前向花键163与卡盘体152的花键153 (如图10所示)相互作用。 For example, the sleeve 160 having a forward spline 163 (FIG. 10), 152 spline 153 (FIG. 10) to the interaction of the precursor spline 163 and the chuck. 套筒160具有凹穴168 (如图11所示),用以可选择地与机壳190的凸耳198接合。 Sleeve 160 having a recess 168 (FIG. 11), to selectively engage with the lugs 190 of the housing 198.

[0058] 套筒160 (相对于卡盘体152)的轴向位置受锁销157的影响。 [0058] The sleeve 160 (relative to the chuck body 152) affected by the axial position of the lock pin 157. 在变化的实施例中,设置有多个锁销157。 In a variant embodiment, a plurality of lock pin 157 is provided. 锁销157由弹簧159沿径向向外偏压。 The lock pin 157 biased radially outwardly by a spring 159. 锁销157和弹簧159容纳在卡盘体152的凹穴中。 The lock pin 157 and a spring 159 received in the chuck body 152 in a pocket. 锁销157与套筒160的凹槽167的相互作用,以便影响套筒160的轴向位置,下面将详细叙述。 The lock pin 157 interacts with the recess 167 of the sleeve 160, in order to influence the axial position of the sleeve 160, as will be described in detail.

[0059] B.操作 [0059] B. Operation

[0060] 工具卡盘150根据套筒160轴向位置的不同能够以不同模式操作。 [0060] The tool chuck 150 may operate in different modes according to the different axial positions of the sleeve 160. 这些不同操作模式包括(但并非限于)钻孔/驱动模式、装配模式和卡固模式。 These different modes of operation including (but not limited to) the drill / driving mode and a latching mode assembly mode.

[0061] 图12所示为钻孔/驱动模式。 [0061] FIG. 12 is a drill / driving mode. 如图所示,套筒160定位在相对于卡盘体152的轴向中间位置。 As shown, the sleeve 160 is positioned axially intermediate position relative to the chuck body 152. 在这种状态下,锁销157位于凹槽167中配设的两个斜面161、162之间。 In this state, the lock pin 157 is located between the two inclined surfaces 161, 162 disposed in the recess 167. 套筒160的轴向位置在使用中会发生偏移。 The axial position of the sleeve 160 of the shift will occur in use. 当这种偏移期间,斜面161、162和弹簧加载的锁销157相互作用,以影响套筒160回到所示的轴向中间位置。 When this offset period, the ramp 161 and a spring-loaded latch pin 157 interact to influence the axial position of the intermediate sleeve 160 back to the FIG.

[0062] 此外,衬套110的花键116与套筒160的后向花键166接合,致使卡盘体152、卡盘驱动轴155 (包括衬套110和驱动套筒120)以及套筒160旋转地锁定在一起,并且作为一个单元旋转。 [0062] In addition, splines 116 of the bushing 110 and the sleeve 160 engages the splines 166, 152 so that chuck body, the chuck shaft 155 (including the drive sleeve 120 and the liner 110) and a sleeve 160 rotationally locked together and rotate as a unit. 这样,工具卡盘150在工作中不会松动。 In this way, the tool chuck 150 is not loosened at work.

[0063] 使用者启动驱动器,旋转驱动输出轴130,驱动输出轴130依次又旋转驱动工具卡盘150和附件105。 [0063] The user starts the drive, the rotary drive output shaft 130, in turn, drives the output shaft 130 rotationally driving the tool chuck 150 and accessory 105.

[0064] 图13所示为装配模式。 [0064] Figure 13 shows the assembly mode. 使用者移动套筒160到轴向前向位置,以实现装配模、式。 Before the user moves to a position axially to the sleeve 160, to achieve loaded module formula. 在这种轴向运动中,凹槽167的斜面161在径向向内方向上驱动锁销157,并克服弹簧159的影响。 In such axial movement, the inclined surface 161 167 recess in the radially inward direction to drive the locking pin 157 and against the influence of the spring 159. 套筒160活动地保持在轴向前向位置,致使衬套110的一部分能暴露出来。 Sleeve 160 axially movably held in the forward position the front, so that a portion of the liner 110 can be exposed.

[0065] 衬套110的暴露部分可被工具抓持,以允许将工具卡盘150装配到动力驱动器的输出轴130上,或者将其从输出轴130上卸下。 Exposure [0065] The liner 110 may be part of the tool holding catch, to allow the tool chuck 150 is fitted to the power drive output shaft 130, or to remove it from the output shaft 130. 一旦释放活动保持时,斜面161和弹簧加载的锁销157就能够相互作用,以使套筒160回到如图12所示的轴向中间位置。 Once the release of an active hold, the ramp 161 and a spring-loaded lock pin 157 can interact, so that the sleeve 160 back to the neutral position shown in FIG. 12 axially.

[0066] 图14所示为卡固模式。 [0066] FIG. 14 is a retaining mode. 在此,使用者可将套筒160移到轴向后向位置。 After this, the user can move the sleeve 160 to axially position. 在该初始轴向移动时,凹槽167的斜面162在径向向内方向上驱动锁销157,并克服弹簧159的影响。 When the initial axial movement, the inclined surface 162 of the recess 167 in the radially inward direction to drive the locking pin 157 and against the influence of the spring 159. 在进一步的轴向移动中,锁销157 (在弹簧159的作用下)沿径向向外方向移动,并跨过斜面164。 In a further axial movement of the lock pin 157 moves radially outward direction (the action of the spring 159), and across the inclined surface 164.

[0067] 此外,套筒160的后向花键166脱离衬套110的花键116,以使卡盘驱动轴155 (包括衬套110和驱动套筒120)能够相对卡盘体152旋转。 [0067] Further, the rear sleeve 160 from sleeve 110 splined to splines 116 of 166 to the chuck shaft 155 (including the drive sleeve 120 and the liner 110) 152 capable of rotating relative to the chuck body. 端盖194的凸耳198进入到套筒160的凹穴168中。 Lugs 198 of the end cap 194 into the pocket 168 of sleeve 160. 在这种状态下,套筒160、卡盘体152、凸头部140、爪保持器145和卡爪101能旋转地安装在动力驱动器的机壳190上。 In this state, the sleeve 160, the chuck body 152, the convex head 140, the claw 145 and the claw holder 101 rotatably mounted on the casing 190 of the power drive.

[0068] 然后使用者启动驱动器以旋转驱动输出轴130。 [0068] The user then starts the driver drive the output shaft 130 to rotate. 输出轴130可旋转驱动衬套110。 The output shaft 130 is rotatably driven bushing 110. 衬套110通过离合面112和122之间的接合而旋转驱动驱动套筒120。 By the engagement between the bushing 110 and 122 of the clutch face 112 is driven to rotate the drive sleeve 120. 驱动套筒120相对于卡盘致动螺钉180旋转,其(通过卡爪101、凸头部140、爪保持器145、卡盘体152和套筒160)保持在机壳190上。 The drive sleeve 120 relative to the chuck actuating screw 180 rotates, (via pawl 101, the convex head 140, the pawl holder 145, the chuck body 152 and sleeve 160) held on the housing 190. 这种相对旋转导致卡盘致动螺钉180通过径向向内面螺纹128和径向向外面螺纹188之间的相互作用,沿轴向方向上前进或后退(根据驱动套筒120的旋转方向)。 This relative rotation causes the chuck actuating screw 180 threaded through the radially inward face 128 and radial, forward or backward to the outside of the interaction between threads 188 in the axial direction (the direction of rotation of the drive sleeve 120). 卡盘致动螺钉180的这种移动能够推或拉卡爪101 (由爪保持器145上的倾斜槽147导引),以使其张开或闭合。 Such movement of the chuck actuating screw 180 can pull or push the pawl 101 (held by the pawl 145 on the inclined guide groove 147), so as to open or closed.

[0069] 在卡盘致动期间,套筒160、卡盘体152、凸头部140、爪保持器145、卡爪101和卡盘致动螺钉180保持旋转地安装在机壳190上,同时卡盘致动螺钉180可相对卡盘体152在轴向上移动(通过驱动套筒120的旋转运动),以张开或闭合卡爪101。 During the [0069] chuck actuation, the sleeve 160, the chuck body 152, the convex head 140, the retainer pawl 145, pawl 101 and the chuck actuating screw 180 held rotatably mounted on the casing 190, while a chuck actuating screw 180 may be moved relative to the chuck body 152 (by the rotational movement of the drive sleeve 120) in the axial direction to open or closed pawl 101. 由于使用者不容易受到(或观察到)任何旋转部件的影响,这就被称为所谓“静轴”特征。 Since the user is not susceptible to (or observe) any rotating member, characterized in which a so-called "dead axle."

[0070] 输出轴30相对于卡盘体52 (其通过套筒60旋转地安装在机壳90上)旋转驱动卡盘驱动轴55。 [0070] The output shaft 30 relative to the chuck body 52 (through the sleeve 60 which is rotatably mounted on the casing 90) rotatably driven chuck shaft 55. 如'503申请所述,卡盘驱动轴55和卡盘体52 (并因此卡盘致动螺钉和卡爪)之间的相对旋转可致动工具卡盘50 (也就是根据动力驱动器的操作方向张开和/或闭合卡爪)。 The '503 herein, the chuck shaft 55 and the chuck body 52 (and thus the chuck actuating screw and the jaw) may be relative rotation between the chuck actuating tool 50 (i.e. the direction of operation of the power drive according to opening and / or closing the jaws). 此外,在卡盘致动过程中,卡盘体和卡爪不旋转。 Further, the chuck actuation process, the chuck body and the pawl does not rotate.

[0071] 在卡盘致动过程中,当工具卡盘150没有完全打开或关闭时(比如卡爪101仍正在打开或关闭时),衬套110通过离合面112和122之间的相互作用旋转驱动驱动套筒120。 [0071] In the chuck actuation process, when the tool chuck 150 is not fully opened or closed (for example, the pawl 101 is still being opened or closed), the bush 110 the interaction between the 112 and the 122 of rotation by the clutch surface a drive sleeve 120. 当工具卡盘150完全关闭(有或没有插入的附件105)或完全打开时,衬套110施加到驱动套筒120上的旋转力可加大。 When the tool chuck 150 is fully closed (with or without insertion of the attachment 105) or fully opened, the liner 110 is applied to a rotational force on the drive sleeve 120 can be enlarged. 该旋转力增加到一阈值,在该阀值下离合面112和122就会让开(或滑动),以限制卡盘致动过程中施加的转矩。 The rotational force is increased to a threshold, the threshold at 112 and the clutch surface 122 so that it will open (or sliding), the chuck to limit the torque applied during actuator motion. 当离合面112和122滑动时,驱动套筒120 (与卡盘体152和套筒160 —起)将沿轴向向前方向被驱动并克服弹簧106的影响。 To be driven in the axial and forward direction against the influence of the spring 106 - when the clutch surface 112 and the slide 122, the drive sleeve 120 (since the chuck body 152 and sleeve 160). 然而,应该理解,这种轴向向前运动(发生在离合滑动时)不足以使端盖194的凸耳198脱离套筒160的凹穴。 However, it should be understood that forward axial movement (when the clutch sliding occurs) is not sufficient to cover the lugs 198 from the pocket 194 of sleeve 160.

[0072] 将可理解,在轴向向前方向上驱动驱动套筒120所需旋转力的值,受到如离合面112和122几何构造和/或弹簧106的弹簧常数的影响。 [0072] It will be appreciated, the desired value of the rotational driving force of the sleeve 120 in an axial forward direction, as affected by surface 112 and the clutch 122 and the spring constant geometry / or spring 106. 此外,通过适当设计离合面112和122的几何构造,使紧固工具卡盘150的转矩阈值小于松开工具卡盘150的转矩阈值,反之亦然。 Further, by appropriate design of the clutch faces 112 and 122 of the geometric configuration, the fastening tool chuck 150 is smaller than the torque threshold release torque threshold tool chuck 150, and vice versa. ,
