The present disclosure provides a cleaning machine that simplifies the structure around a turn table. The cleaning machine (10) of the present disclosure comprises a cleaning table (31), a rotation mechanism (40), and a first flow path (5a˜5e). The rotation mechanism includes a motor (42), a first bevel gear (44), a reducer (50) having an output shaft (52) and an input shaft (51), a second bevel gear (56), a first swivel housing (60) inserted into the input shaft (51), a first swivel shaft (61) arranged inside the first swivel housing, and a first flange (62). The first flow path includes a first annular path (63a˜63e), a first upstream flow path (64a˜64e), and a first downstream flow path (65a˜65e) arranged inside the first swivel shaft and connected to the first upstream flow path via the first annular path.

The present disclosure includes a part hold-down assembly for retaining an oversized part. The part hold-down assembly is aligned along a central force axis and applies a downward force onto the part. The part-hold down assembly includes a top plate, a bottom plate, and a compression assembly extending between the top and bottom plates. The compression assembly includes two, parallel biasing assemblies that extend along compression axes that are parallel to but offset from the central force axis. Each biasing assembly including an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The parallel biasing assemblies are positioned on opposite sides from each other about the central force axis, and may be spaced away from the central force axis an equal distance.

A machining system configured to reduce spring back following machining operations comprising a machining tool and a spring back control system. The spring back control system comprises a number of force generators and a number of force loaded members coupled to the number of force generators, each force loaded member of the number of force loaded members comprising a material contact surface. The material contact surface is a roller, wherein the machining tool is independently moveable relative to the spring back control system.

A fixture to hold a workpiece comprising, among other things, a housing having a passage opening into which a clamping pin is inserted for supporting the workpiece; a driving ring mounted in the housing; and at least two locking pins facing the axis of the opening, mounted radially in the housing so as to be able to move, wherein the clamping pin is locked in the opening of the housing when the locking pins are moved toward the axis, and released from the passage opening of the housing when the locking pins are moved away from axis; wherein, a control surface with at least two different pitches is worked onto an inside of the driving ring, and a contact surface is worked onto an inner wall of the driving ring so as to permit movement of the locking pins by rotation of the driving ring.

A clamp to retain a block of material on a machining table including a body having a first face, a first front face oriented toward the machining table and the block of material when in use, a nose projecting relative to the first front face having a second front face parallel to the first front face, first and second edges connecting the first and second front faces, and at least one internally threaded hole opening at least partly at the level of the second front face with an axis forming a non-zero angle with the first face and the second front face, at least one grub screw screwed into the internally threaded hole having a pointed free end configured to penetrate into the block of material when in use when screwing in the grub screw, and a connecting system to demountably connect the clamp to the machining table.

The purpose of the present invention is to facilitate bonding between a jig and a plate-shaped workpiece and to suitably support the workpiece. A support device is provided with: a jig that has a bent support surface for supporting a plate-shaped workpiece; a first abutment that abuts against one end of the workpiece mounted on the support surface; and a second abutment that is disposed so as to face the first abutment across the support surface and that abuts against the other end of the workpiece mounted on the support surface. The first and second abutments move toward each other and apply a load, in the tangential direction load of the support surface, with respect to the workpiece mounted on the support surface.

An adjustable clamp for the retention of a vice or work piece onto a slotted worktable. The clamp has a raised rear foot that both spans the standard width of a slot in a slotted worktable regardless of the angle the clamp is secured to the worktable, and generates an increased gripping force at both contact points of the clamp. Its nose accommodates a cylindrical pin recess to accommodate a cylindrical pin to allow the vice to clamp to a vice with a raised peripheral lip. The 30 degree beveled front edge allows the clamp a substantial planar contact surface with the vice or work piece, enhancing stability.

A machining system configured to reduce spring back following machining operations comprising a machining tool and a spring back control system. The spring back control system comprises a number of force generators and a number of force loaded members coupled to the number of force generators, each force loaded member of the number of force loaded members comprising a material contact surface.
