A blade clamping device for a microtome is provided. The blade clamping device includes: a base part; a pressure plate rotatably connected to the base part via a rotation shaft; a clamping pin received in the base part, and configured to extend out of the base part and push the pressure plate to rotate, so as to clamp a blade between the base part and the pressure plate; and a drive unit received in the base part, connected to the clamping pin and configured to drive the clamping pin to extend out of the base part.

A device for holding in position a product to be processed includes a base connectable by magnetic interaction to a work surface of an apparatus for tumbling or polishing and comprising a first portion and a second portion movable along an operating direction mutually towards or away from a first and a second operating position. The device also includes a retaining support connected to the base and configured to hold in a stable position a product to be processed between a first and a second retaining element. Between the first and the second portion of the base an actuation member is interposed, configured to move the same portions between the first operating position and the second operating position. A method for holding in position a product to be processed is also disclosed.

A chuck unit includes a first pressure chamber and a second pressure chamber disposed on both sides of a piston for driving fingers. A valve unit includes a first output air flow path connected to one of the first and second pressure chambers, a second output air flow path connected to the other thereof, a first solenoid valve connected to the first output air flow path, and a second solenoid valve connected to the second output air flow path. The first solenoid valve connects the first output air flow path to an air supply source when energized and opens the first output air flow path to atmosphere when de-energized, and the second solenoid valve opens the second output air flow path to atmosphere when energized and connects the second output air flow path to the air supply source when de-energized.

A fixture assembly may include a housing, a clamp assembly, and a drive mechanism. The clamp assembly may be movably mounted to the housing and may include a first clamp member and a second clamp member. The first and second clamp members may be linearly movable relative to the housing toward and away from each other. The drive mechanism may be coupled to the clamp assembly and the housing and may drive the clamp assembly relative to the housing such that the first clamp member moves linearly toward the second clamp member at a first speed in a first direction and the second clamp member moves linearly toward the first clamp member at a second speed in a second direction that is opposite the first direction. The first speed may be different than the second speed.

A clamp assembly a fixed end support, a movable end support and a handle disposed in one end support or the other. The handle is rotated using an electric tool, such as a drill. A female receiver is disposed within a rearward end of the handle. A male driver is removably held within a chuck of the electric drill and is inserted into the receiver to rotate and then tighten or loosen the support end of the clamp. Alternatively, the clamp assembly has a male portion that is disposed at a rear portion of an end support and a female driver is used to rotate and then tighten or loosen the clamp from the wood pieces. The female receiver and male driver can be used with either a movable end support or a stationary end support of the clamp, as could the male portion and the female driver.

A vise assembly has a base and a pair of side walls extending from the base and providing guideways. A jaw is configured for guided movement by the guideways. An actuator is coupled to the jaw to cause movement of the jaw. A support supports at least a portion of the actuator. A biasing element is configured to urge the actuator to engage the support.

A fluid pressure vise actuator includes a housing and an inner bore of the housing. A piston is disposed in the housing, and the piston is configured to actuate based on a pressure increase in ports of the housing. A gear is also disposed in the inner bore of the housing, and a portion of the gear is adjacent to the piston such that an actuation of the piston is configured to rotate the gear. The gear includes a socket configured to interface with a vise and operate the vise based on a rotation of the gear. The housing also includes adjustable clamping blocks configured to engage with the vise to provide support for the housing during operation. An adjustment of the clamping blocks enables the fluid pressure vise actuator to interface with multiple types of existing vises.

A human-robot collaboration (HRC) workstation includes a robot having a robot controller and a robot arm comprising a plurality of joints and links connecting the joints. The joints are automatically adjusted by the controller to move or hold in space a tool or workpiece held by the robot arm by adjusting the joints. The (HRC) workstation further comprises a mounting device having a stationary base frame and a fixing device configured to hold in place a workpiece or a tool such that the workpiece and/or tool held on the mounting device may be assembled and/or machined in interaction with the robot arm. The mounting device includes a mechanical adjusting device and a triggering device controlled by the robot controller and the adjusting device is configured to automatically adjust the fixing device relative to the base frame from an operating position to a safety position when the triggering device is activated.
