摘要:
The invention relates to an improved dental tool drive arrangement for a handpiece with a drive head, the tool drive arrangement permitting length adjustment of the tool in the drive head by concentrically supporting the tool in the drive head at any position from a fully inserted position to a maximum retracted position. The tool drive arrangement preferably includes a tool and a rotatable tool supporting element for concentrically supporting the tool from the fully inserted to the maximum retracted position, the tool preferably including a maximum retraction indicator for indicating to a user when the tool has been retracted to the maximum retraction position. This provides a significant advantage over the prior art by allowing a user to adjust the exposed length of a rotatable tool, preferably a dental bur, without exceeding safe operating limits. The invention also relates to an improved drive spindle which allows depth adjustment of a tool in a dental handpiece while maintaining efficient torque transfer and concentricity during high speed rotation.

Various embodiments of power tool and method of operating same are described. The power tool (10) may include a first position sensor (34.1), a second position sensor (34.2), a third position sensor (34.3), and a controller (80). The first, second, and third position sensors may each generate a signal indicative of a distance between the respective position sensor and a workpiece. The controller (80) may determine one or more angles of the power tool with respect to the workpiece based on the first, second, and third signal and present an indication as to whether the one or more angles are within a predetermined range. The controller (80) may further obtain a depth measurement based on the first signal, the second signal, and the third signal and generate, based on the obtained depth measurement, one or more control signals that control operation of the power tool.

摘要:
A method for providing haptic feedback is provided for a device that produces haptic noise, such as a power tool with an electric motor that produces noises and vibrations while in operation. An environmental condition of the device can be sensed while the device is being operated and generating haptic noise. A haptic noise characteristic of the device can be determined. A haptic drive signal based on the environmental condition and haptic noise characteristic can be generated. The haptic drive signal can be applied to a haptic output device associated with the device.
摘要:
A display structure of a drilling machine includes a digital display control assembly (20) which includes a liquid crystal control panel (21), a control circuit board (22), a displacement induction controller (23) and a battery seat (24). The liquid crystal control panel (21) is electrically connected with the control circuit board (22). The control circuit board (22) is electrically connected with the displacement induction controller (23). The control circuit board (22) is further electrically connected with the battery seat (24). The displacement induction controller (23) includes an engaging protrusion (230) to engage with a displacement control linking seat (11) of a feed guide body (10). The liquid crystal control panel (21) of the digital display control assembly (20) is adapted to input control signals, such as an initial point, a terminal point and a feed unit, and the control signals are sent to the displacement induction controller (23) via the control circuit board (22). The displacement induction controller (23) receives the signals and returns the signals to the control circuit board (22) for controlling the upward/downward movement of the feed guide body (10). After setting the digital display control assembly (20), the feed guide body (10) can carry out the same feed many times, controlling the feed depth and providing uniformity of drilling.
