    Abstract: A clamping assembly to hold a woodworking knife (324) in place in a woodworking machine. The clamping assembly comprises a first clamping component (306), a second clamping component (308) and an actuator (310). The first clamping component has three descrete contact positions distributed thereon: 1) a fulcrum (326) located generally at one end, 2) a first knife abutting portion (325) located generally at the other end, and 3) a bearing surface (330) located elsewhere. The second clamping component includes a surface defining a second knife abutting portion for engaging a surface on said one or more knives that is opposite the surface thereof engaged by the first knife abutting portion of the first clamping component to clamp said one or more knives between the clamping components; and a substantially planar contact surface located to engage the bearing surface of said first clamping component. The actuator is for applying a clamping force to the first clamping component towards the second clamping component along a clamping axis (328) located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis. According to the invention the first clamping component has a larger length in cross section than the second clamping component, such that when positioning the first clamping component against the second clamping component such that the clamping axis of the first and second clamping components are aligned and the bearing surface and the contact surface abut, the fulcrum of the first clamping component is located a distance outside of the second clamping component.

    Abstract translation: 用于将木工刀（324）保持在木工机器中的夹紧组件。 夹紧组件包括第一夹紧部件（306），第二夹紧部件（308）和致动器（310）。 第一夹紧部件具有分布在其上的三个描述接触位置：1）大致位于一端的支点（326），2）大致位于另一端的第一刀对接部分（325），以及3）支承表面（330） ）位于其他地方 第二夹紧部件包括限定第二刀对接部分的表面，用于接合与所述一个或多个刀具相对的表面，所述刀具与第一夹紧部件的第一刀对接部分接合的表面相对，以将所述一个或多个刀夹在 夹紧部件; 以及基本平坦的接触表面，其定位成与所述第一夹紧部件的支承表面接合。 所述致动器用于沿着位于所述刀抵接部分和所述支点之间的夹紧轴线（328）向所述第二夹紧部件施加夹紧力至所述第二夹紧部件。 支点是具有与夹紧轴线成一角度的法线的表面。 根据本发明，第一夹紧部件具有比第二夹紧部件更大的横截面长度，使得当将第一夹紧部件定位在第二夹紧部件上时，使得第一和第二夹紧部件的夹紧轴线对准，并且 轴承表面和接触表面邻接，第一夹紧部件的支点位于第二夹紧部件外侧的距离处。

    Abstract: A clamping assembly to hold a woodworking knife in place in a woodworking machine. The clamping assembly comprises a clamping component comprising a body and an actuator. The body has three discrete contact positions distributed thereon: 1) a fulcrum located generally at one end, 2) a knife abutting portion located generally at the other end, and 3) a bearing surface located elsewhere. The actuator is for applying a clamping force to the body along a clamping axis located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis. The bearing surface is a surface wherein a line normal to the bearing surface intersects the line normal to the fulcrum at a position outside of the clamping component at a location farther askew of the clamping axis than the fulcrum.

    Abstract: A self-aligning knife clamping assembly (10) and machine incorporating the same are disclosed. In one embodiment there is provided a knife clamping assembly (10) having an outer clamping component (22), an inner clamping component (24) and a fastening device (14), such as a bolt, therebetween, to permit the clamping components to be releasably clamped together onto a knife element (50) having a knife edge. Positioned between the knife element (50) and the clamping assembly is a biasing element (60), which urges the knife element to enter, or remain in, a preferred position prior to the knife element being immovably clamped into place. In the preferred embodiment the biasing element is in the form of an elastomeric strip.
