Definitions

• the present invention relates to a portable workbench, intended to facilitate the practice of various mechanical and similar operations in various locations, for example, at the foot of a construction or similar work.
• the new workbench consists of a frame of great solidity and, at the same time, of remarkable portability, which allows its easy transfer in a vehicle.
• SUBSTITUTE SHEET RULE 26 non-limiting, a case of realization of a portable workbench, according to the principles of the claims.
• Figure 1 is an overall and exploded view of the new workbench, and Figure 2 is a detail of the clamping device.
• Figure 3 is a side elevational view of a variant of the bench, mounted in use arrangement.
• the supporting structure 1, of great strength and resistance constituted by a frame 11 of preferably rectangular shape, defined by a vertical perimeter 12 and a horizontal plane frame 13 on which the tabletop 2 of the table will rest immediately, and four support legs 14, made of an angular profile, foldable by articulation or detachable from the frame and possibly slightly inclined in divergence to the ground.
• the assembly will advantageously be made of sheet steel of the appropriate thickness.
• the table 13 has a hole 15 on its back side intended for the firm anchoring of a clamping arm of the pieces to be machined.
• Worktop 2 has a shape and dimensions adjusted to those inside the perimeter 12 of the frame of the frame. It can be of one or several pieces, with the condition of being of great resistance to deformation, and its upper surface will be smooth, but with some roughness to prevent unwanted sliding of parts and tools.
• the board 2 will be made of hard wood or of a light metal, and will have means of fixing to the frame 1, removable for the purpose of transport and storage. At its rear it presents a hole 21 in correspondence with the hole 15 of the frame of the frame.
• the vertical axis 3 forms a support for the clamping device of the parts to be treated and consists of a rod, preferably of carbon and tempered steel, of suitable shape and diameter to give it a high resistance, taking into account the efforts to be made. put up with. It has a threaded section 31 on its foot, intended to be inserted in holes 15 of frame 13 and 21 of the board 2, with the interposition of a washer 32 and final fixing (removable) by means of a nut 33 with its washer or equivalent element.
• the coil spring 34 is arranged externally and axially to the rod 3 and serves to release, at the desired time, the part that is machined on the work board.
• the clamping device of the pieces comprises an articulation block 5, orthopedically, provided with a vertical perforation 51, intended for the insertion of the vertical bearing rod 3, and two parallel perforations for the passage, with the possibility of sliding, of two rods 6 of horizontal movement. These are attached to a second orthopedic block 7, provided with a rectangular recess 71 on one of its vertical faces and a transverse perforation 72.
• the block 7 is a carrier of a rod 73 for fixing an eccentric 8, preferably circular.
• the clamping of the pieces is carried out by means of a lever or arm 9 that has an L-shaped line. Its smaller section 91 is intended to be placed in the recess 71 of the block 7, as indicated in Figure 2, and has a hole 92 that will correspond to the transverse perforation 72, allowing the insertion of a pin 10.
• the above elements define an arm horizontal that essentially constitutes the support and fastener of the pieces to be machined, in which three fundamental movements are possible: a) vertical of the horizontal arm, parallel to itself, on the vertical axis 3; b) rotating the horizontal arm, in its plane, with respect to the axis 3 itself, and c) horizontal of the arm, in its plane, by sliding the rods 6 with respect to the block 5.
• the eccentric 8 is cylindrical and has a side arm 81 for its operation that facilitates the tightness of the retained parts. Determine the effort made on the lever 9 and the latter on the part retained at all times for machining.
• the components of the described device will be suitably sized to be able to withstand and transmit considerable efforts, according to the auxiliary operations that are planned for its realization on the workbench.
• Figure 3 shows a portable workbench whose configuration presents some structural variants with respect to the embodiment of Figures 1 and 2, but maintaining the general idea of a supporting frame 1, a support that can adopt a vertical position 94 and a horizontal position 95, mobile according to the arrows, with the possibility of having the three fundamental movements indicated above for the desired clamping and orientation device 96 of the pieces.
