According to at least one embodiment, a gravity assist system comprises a plurality links and a means for holding at least one tool, wherein the plurality links are configured to permit a user to reposition the at least one tool within a work envelope.

A modular machine tool processing jig includes a base body having at least a positioning device and a movement adjusting device; at least a clamping positioning seat fixed on the base body through the positioning device and having at least a positioning clamping face, by which providing an efficient and accurate positioning effect; and at least a clamping adjusting seat disposed on the base body through the movement adjusting device, so as to adjust the interval between the clamping adjusting seat and the clamping positioning seat along an axial direction for different workpiece sizes. Therein, the clamping adjusting seat has at least a clamping assembly having at least a clamping face. The clamping assembly adjusts the interval between the clamping face and the positioning clamping face for clamping a to-be-processed workpiece.

A printing system for printing substrates, in particular printed circuit boards, includes a printing device having at least one printing table and a printing template assigned to the printing table. The printing system further includes a first pair of first slide elements and a second pair of second slide elements for aligning a substrate on the printing table. The first pair of first slide elements can be displaced counter to one another along a first axis. The second pair of second slide elements can be displaced counter to one another along a second axis, which differs from the first axis. A drive device is assigned to each pair for simultaneously displacing the slide elements thereof.

A self-adjusting static pressured plane guide rail consists of a base, slider provided on the base and an upper pressing plate corresponding to the shoulders on both sides of the slider; wherein: each upper pressing plate's outer edge contacts the base to form a fulcrum and the upper pressing plate's inner edge acts as the force portion and a upper pressing block is set between force portion and the slider's shoulder and a metal wire is set between the upper pressing block's top surface and the force portion's bottom surface of upper pressing plate along the slider's sliding direction; the upper pressing plate is provided with pre-tightening bolt to connect the base in a fixed way. When vibration frequency changes during operation, the oil film gap changes accordingly due to pre-tightening bolt's elasticity of the mutual function and the metal wire's elasticity to always maintain oil film layer's rigidity function.

A woodworking jig to hold lumber may include a central column; a chainsaw support assembly to slidably connected to the central column; an angle grinder support assembly to slidably connect to the central column; and a vertical log support to support the lumber positioned alongside of the central column.

A movement-guiding device that includes a moving rail having a rolling element rolling surface; a first block that engages with the rolling element rolling surface of the moving rail via a plurality of rolling elements; a fixed rail including a rolling element rolling surface; a second block that engages with the rolling element rolling surface of the fixed rail via a plurality of rolling elements; and a joint member. The joint member is formed in a plank shape and connects the moving rail and the fixed rail by having the first block mounted on one surface and having the second block mounted on the other surface. The joint member is formed having a height difference.

A worktable for tile cutter with water drainage assembly includes a movable platform and a pivotable guiding member. The movable platform has a drainage channel defined therein. The guiding member has a diversion channel defined therein and communicated with the drainage channel. The guiding member has a first diversion opening and a second diversion opening respectively located on two ends thereof. When the movable platform is in a first position, the first diversion opening is inclined downwards such that the diversion channel guides the water from the drainage channel through the first diversion opening to a water collection tank located under the movable platform. When the movable platform is in a second position, the second diversion opening is inclined downwards such that the diversion channel guides the water from the drainage channel to the water collection tank. Therefore, the draining worktable can provide a good drainage effect.

A system to adjust extension lengths of slats of a work platform relative to a workpiece includes sensors to collect first data associated with a position of an outer surface of the workpiece at a height of the slats. The system includes actuators configured to extend or retract the slats. The system also includes a controller coupled to the sensors and to the actuators. The controller is configured to receive the first data and second data associated with rotation of the workpiece. The controller is configured to provide signals to the actuators of the work platform based on the first data and the second data. The signals cause the actuators to adjust or maintain extension lengths of the slats of the work platform to maintain separation distances between ends of the slats and the outer surface of the workpiece within a separation distance range as the workpiece rotates.

A tool assembly for attaching to two carriages of a carriage guide rail system; wherein the two carriages are movable along the carriage guide rail relative to one another, the tool assembly having a base and a linear actuator movable relative to the base; wherein the base has a first connector for attaching to one of the two carriages; wherein the linear actuator has a second connector for attaching to the other one of the two carriages; wherein the base has a first base portion attaching to the first connector; wherein the first base portion is arranged between at least a part of the linear actuator and the two connectors in a direction perpendicular to the carriage guide rail.
