A dust collection device for an electric power tool includes a main body case that includes an air exhaust port and is attachable to a hammer drill, a dust box provided therein with a filter, and a tubular sliding portion that has a base end connected to a connection port provided on the main body case, that includes a suction port at its front end, and that is slidable in a front-rear direction, and includes therein a dust collection path formed to pass from the suction port through the filter to the air exhaust port. The connection port is provided on a side surface of the main body case, and connected to a flexible hose serving as a base end of the sliding portion, and a side surface of the dust box is provided with an inlet port communicating with the connection port.

In an example, a clamp foot for a clamp assembly includes a housing having a distal end for engaging a workpiece, an aperture in the distal end of the housing, and a cavity in the housing extending proximally from the aperture. The clamp foot also includes a flapper in the cavity and adjacent to the distal end. The clamp foot further includes a pneumatic port in the cavity configured to direct a pneumatic force from a pneumatic source to the flapper, and a vacuum port in the cavity for coupling the cavity to a vacuum source. Responsive to the pneumatic force, the flapper is movable within the cavity to separate debris from the workpiece. The vacuum port is configured to remove from the cavity, via a vacuum force from the vacuum source, the debris separated from the workpiece by the flapper.

A power tool system includes a power tool and a dust collector operable to collect debris generated during operation. The power tool includes a housing, a working end, and a tool bit extending from the working end. The dust collector includes a mounting base seated against the working end, a tether coupled to the mounting base, and a shroud extending from the mounting base. The mounting base defines an aperture through which the tool bit extends. The tether is wrapped around a portion of the housing to secure the dust collector to the power tool. The shroud has a first end adjacent the mounting base, a second end operable to contact a workpiece, a sleeve extending between the first end and the second end, and a spring biasing the second end away from the first end. The second end is movable relative to the first end against the spring.

A drilling end effector may include a motor operative to drive a drilling member, a housing surrounding the motor, and a vacuum shroud coupled to the housing and surrounding the drilling member, wherein the vacuum shroud has a variable length.

A method for processing a drilling location in a confined area of a workpiece along a drilling axis A using an end effector is disclosed. The method comprises positioning the end effector relative to the drilling location of the workpiece, clamping the workpiece between a clamp of the end effector and a pressure foot of the end effector, wherein the pressure foot supports the clamp movable relative to the pressure foot, and drilling the workpiece with a flat angle drill of the end effector.

A cutting machine waste extraction apparatus is provided for a cutting machine that cuts a plate where the cutting machine waste extraction apparatus is supported adjacent a cutting area at a cutting table. The cutting machine produces waste at the cutting area during the cutting of the plate where the apparatus includes a ducting system having a first duct that receives the waste from the plate, and a second duct that receives the waste from the first duct. The first duct is movable along the length of the second duct and the second duct includes a lengthwise opening which is sealed by a flexible belt. The flexible belt is deformable from sealed contact with the second duct, adjacent a junction apparatus, where the junction apparatus provides a fluid connection between the first duct and the second duct.

Apparatus and methods for performing and controlling the sequence of steps in a multi-step machining process utilizing a plurality of drilling units, where each drilling unit is configured to perform at least one step of the multi-step machining process. Air pressure sensors in each drilling unit measure air pressures at the surface of a workpiece where the cutting tool of the drilling unit is engaged, which measured air pressures indicate air flow at the surface. These air flows in turn indicate the state of the machining at the surface of the workpiece, and based on the state of the machining, a machine control system will determine whether a drilling unit can perform its particular machining operation in the proper sequence on the workpiece.

A power tool includes a drilling tool and a dust collector configured to be removably attached to the drilling tool. The dust collector includes a dust collector body, a passage part provided in the dust collector body and having elasticity, and a storing part configured to be removably attached to the dust collector body and to store dust. The passage part includes a drilling tool mounting port part configured to be connected to the drilling tool while pressing a specified region of the drilling tool, and a storing part mounting port part configured to be connected to the storing part while pressing a specified region of the storing part. Air containing the dust is led through the dust collector body to the storing part, and the air from which the dust has been separated in the storing part is led through the passage part into the drilling tool.

One example of the present disclosure relates to an apparatus for processing a workpiece along a drilling axis, the apparatus comprising an end effector. The end effector comprises a pressure foot, a clamp linearly movable relative to the pressure foot along the drilling axis, and a flat angle drill linearly movable relative to the pressure foot along the drilling axis.

A suction extraction device has a fan, a suction head, a channel leading from the suction head to the fan, a dust filter and a collection container to hold the dust that has been deposited on the dust filter. The suction head has a tubular cavity that is arranged around the working axis and that serves to accommodate the connection section of the suction drill bit. Arranged in the cavity is a flow sensor that has a sensor surface facing the working axis and that serves to emit a measuring signal that is indicative of the air flow that is striking the sensor surface. An evaluation unit emits an error signal in response to the measuring signal if the measuring signal is lower than a threshold value for at least a prescribed period of time, whereas it suppresses the error signal if the measuring signal exceeds the threshold value during the prescribed period of time. A signaling unit displays the error signal to a user.
