A workholding system includes a quarter turn fastener used in workholding applications to quickly hold and release objects, such as tooling, parts, and plates. In one embodiment, a T-slot fastener facilitates the creation of an entire workholding system that facilitates the rapid installation of studs into receiving members. The compact design also makes possible the ability to insert the quarter turn fastener into a device that can fit into a T-slot and still have considerable holding power. The system is lower in cost than other solutions.

An improved anchor bar for isolating an adjustment force applied to the bar to result in an expansion force directed primarily outward to the sides of the anchor bar and to improve frictional contact with a work surface groove or slot.

The present invention relates to a clamping mechanism that is configured to securely hold a workpiece in a machine tool, such as, but not limited to a vertical machining center, or a horizontal machining center, etc. More specifically, the clamping mechanism is configured as a modular soft jaw. A multiplicity of clamping mechanisms can be used to cooperatively secure large workpieces. Furthermore, a multiplicity of clamping mechanisms can be incorporated into a job set-up so a multiplicity of workpieces can be processed concurrently. The present invention's clamping mechanism can be secured in orientations such as, but not limited to a machine tool table bed, a fixture plate, a tombstone, etc. The present invention's modular, soft jaw clamping mechanism can be used in conjunction with other work holding equipment, such as, but not limited to jigs, fixtures, tools, vises, clamps, etc.

The adaption device is fastened to a workstation, and fixtures may be conveniently and reliably joined or detached from the adaption device. The adaption device mainly includes a main member having a number of sockets on a front side for mounting a fixture. Inside the main member, there are specifically-shaped blocks in an indentation of the main member, a shaft with dual sets of threads of opposite directions driving the blocks to move away from or towards each other, and rods in radially directional ducts driven by the blocks to move along the ducts into the sockets to lock the fixture 30 and automatically restored by elastic elements. A fixture as such may be conveniently, reliably, and precisely installed on a workstation through the adaption device, and the adaption device allows the manufacturing of products of large varieties to be conducted economically and efficiently.

A grid-type workpiece carrier includes parallel strip-type first grid elements having recesses, and strip-type second grid elements arranged transverse to the first grid elements and having recesses, wherein the recesses of the first and second grid elements engage in one another in such a way that the crossing first and second grid elements form a grid, wherein the first grid elements are mechanically securely fixed to second grid elements that are arranged in an edge region on opposing sides of the grid.

A cutting device includes a box, a workbench disposed on the box, and a cutting assembly disposed on the box, where the workbench includes a platen for carrying a workpiece, and the platen is provided with a first cutting slot along a first direction; the platen is slidably connected to the box along the first direction, and when the platen slides towards the cutting assembly, the cutting assembly penetrates through the first cutting slot so that the cutting assembly cuts the workpiece on the platen, where a slide stroke of the platen is greater than a cutting stroke of the workpiece.

A work holding fixture manufactured out of one single block of metal, usually aluminum. The size of the block may vary according to the size and weight of the workpiece to be held. A dovetail shape cut with female characteristics is machined on the top face of the fixture, the dimension of this dovetail shape cut also vary according to the size of the workpiece. Two more cuts are added to the fixture to make the fixture somewhat flexible. One of these cuts is machined on the center of the fixture and perpendicular to the dovetail shape cut and the other cut parallel to the dovetail shape cut. To hold the workpiece in the work holding fixture: The same size dovetail shape must be machined on one of the faces of the blank. The dovetail shape cut must have the same dimension as the dovetail shape cut on the work holding fixture but have male characteristics. Once the dovetail shape cut is machined the blank slides easily in the work holding fixture. The blank is tightened with 10-32 screws. At this point the blank is ready to be applied to the desired manufacturing process.

A squeezer holder device for the holding a hand rivet squeezer on a bench top for improved part control and squeezer operation. The squeezer holder device also provides convenient storage for a hand squeezer and associated dies. The central feature of the invention is the simple slot and die holders designed into a single block. The squeezer holder device allows the user to position a squeezer on any benchtop at a user selected orientation. The squeezer holder device enables accurate control of parts with one hand throughout squeezer operation by using the table surface to operate the lower squeezer lever. The squeezer holder device can be easily slid around a benchtop with the squeezer and dies between operations. When squeezer use is completed the squeezer holder device holds the squeezer in an upright space saving position with associated dies.

A T-Nut for use in a machine tool having a tooling plate with an inverted T-shaped channel. The T-Nut comprises a central body having oppositely inclined faces each including an opening forming a cavity extending through the central body, and first and second wedges in slideable communication with the central body inclined faces. Each of the wedges have wings extending laterally beyond the central body to engage upper surfaces of the channel lower wide portion and include a clearance hole extending through a length of the wedge. A rotatable actuation member abuts the first wedge at an end opposite the first wedge mating surface and is internally threaded for a distance from one end thereof. An externally threaded cylindrical shaft is engaged with the internal threads of the actuation member and extends through the first and second wedge clearance holes, the shaft being secured to and non-rotatable with the second wedge. In operation, when tooling is secured to the top surface of the central body and the actuation member is rotated, the first and second wedges are slideably moved symmetrically along the central body inclined faces until the first and second wedge wings engage upper surfaces of the channel lower wide portion while the tooling is simultaneously urged in the direction of the tooling plate until the tooling mounting surface bears against the tooling plate top surface, thereby removably securing the tooling to the tooling plate.

An improved tooling, including: a base housing having an interior and tooling holes, the tooling holes being configured to receive alignment studs attached to a tooling fixture; a first clamping fixture and a second clamping fixture fit inside hollowed regions within the base housing; a shaft having a length and an axis along the length of the shaft, the shaft situated inside the base housing and the shaft having a first threaded region and a second threaded region to connect the first clamping fixture and the second clamping fixture, whereby rotation of the shaft causes the first clamping fixture and the second clamping fixture to move towards and away from each other along the axis of the shaft; each of the first clamping fixture and the second clamping fixture comprising one or more securing mechanisms configured to: engage and disengage the alignment studs based upon rotation of the shaft.
