One pair of the brackets is fixed on the transverse beams, and the other pair of the brackets is connected with the nuts arranged on the screw rod arranged in the notches of the transverse beams. A handle is arranged on one end of the screw rod, and a plurality of jacks are respectively arranged on the two brackets. One to two pairs of the hammer-shaped jaws are chosen for inserting into corresponding jacks according to the shape, the size, and the length of the holding workpiece. When the utility model is in use, the handle is cranked and the tong plate is moved by the screw rod, so the workpiece can be clamped by the jaws arranged on the tong plate. The utility model can clamp long large and irregular shaped workpieces, having the advantages of foldable structure, light weight, and convenience.

Description

Foldable working bench for benchwork

The utility model relates to a kind of collapsible fitter's bench, the especially fitter's bench of being made up of folding rack and nipper.

When people move into the new home, or when in the room, needing to improve, repair, increase the function of use of some facility, can't do without metalwork, timber, working of plastics are done some processing, this just needs a kind of clamping device of energy clamping processing work, so that firmly finish the processing operation on clamping device.Existing special-purpose clamping device vice is commonly called as bench vice, and it is at processing work, when finishing operation such as cutter, saw, file, boring, fraising, screw thread processing and assembling, must firmly be installed in solid work edge of table.Bench vice utilizes screw rod or other mechanism, and two jaws of bench vice are relatively moved and clamping work pieces.This fitter's bench specificity is strong, firm solid, but its thick heaviness, should not move, the a pair of jaw that is used for holding workpiece on the bench vice, length, big or erose workpiece clamp are held bigger limitation, and workpiece easily produces displacement and rocks in process, be not suitable for family or non-professionality ground and use.

The purpose of this utility model provide a kind of lightly, folding fitter's bench easily, can fold reduced volume when not only standby, and length, big, irregularly shaped workpiece firmly can be clamped in use.

For reaching above-mentioned purpose, folding fitter's bench of the present utility model is made up of the nipper that folding stand and screw rod move.Four pin of folding stand are movably connected in respectively on two downward grooved crossbeams of notch, put strut and pole between two pin on the same crossbeam, on the crossbeam between the pin of same position, be connected and fixed with the crosspiece of double as tool rack, the bending pole can make pin draw in.Respectively have one and screw rod in the groove of grooved crossbeam, screw handle is positioned at an end of grooved crossbeam, one nut is arranged on the screw rod, nut extends upward bolt, bolt passes the slotted hole on the crossbeam, with can be connected with the carriage that nut moves on the crossbeam, fix another carriage on the crossbeam, have a pair of plate of a plurality of diagonal angles or the jack that is arranged in parallel, be fastened on respectively on two analog brackets and the Movable bracket, hammer shape jaw is according to the size of holding workpiece shape, insert in the corresponding jack selectively, shake handle, two nippers relatively move, and the jaw in the jack on the nipper is clamped workpiece.

After adopting such structure, owing between folding two pairs of pin of stand strut and pole are set, four heel braces are split into splayed during work, firmly the processing operation on the support table can collapse stand when standby, dwindles shared space of fitter's bench and ground location, conform to family and amateur instructions for use, light, can receive the characteristics that engaged position is little by exoergic; Again because direct two pairs of jaws of holding workpiece, can be by workpiece irregularly shaped or length, on nipper, insert jack selectively.Shake handle during work, the screw rod top nut drives Movable bracket relatively moves the nipper that is fastened on the carriage, the two pairs of jaws just can the while clamping work pieces tightly.

The drawing explanation:

Fig. 1 is the front section view of the folding fitter's bench of the utility model.

Fig. 2 is the side sectional view of the folding fitter's bench of the utility model.

Fig. 3 is the vertical view of the folding fitter's bench nipper of the utility model.

Fig. 4 is Figure 1A-A ' face cutaway view

Below in conjunction with drawings and Examples the utility model is described in further detail.

Folding fitter's bench shown in Figure 1, on the downward grooved crossbeam 1 of notch, flexibly connect two pin 2 respectively, bipod is splayed configuration and struts, 2 on pin flexibly connects strut 3 and pole 4, the crosspiece 6 of fixedly connected double as tool rack between the corresponding pin on two crossbeams 1, the groove of crossbeam 1 is built-in with screw rod 7, nut 8 is arranged on the screw rod 7, extend bolt 11 on the nut 8, one end rotating shaft of screw rod 7 is connected an end of grooved crossbeam, handle 9 is installed in the rotating shaft, on the grooved crossbeam 1 of one end of nearly handle 9, with securing member fastening bracket 10, have slotted hole 12 on the other end frid of trough girder, bolt 11 passes slotted hole 12, carriage 13 is fastened on the bolt, respectively fixing nipper 14 on carriage 10 and carriage 13 with hard solid wood system.Have a plurality of jacks 5 on the nipper 14, jack becomes diagonal or is arranged in parallel, and hammer shape jaw 15 inserts jack, and jaw can adopt resilient engineering plastics or poly-ammonia goods.

During use, four heel braces of folding fitter's bench are opened, make four pin firmly support ground, shake two handles, make the translation laterally of movable nipper, according to the workpiece of desire processing operation, with a pair of or two pairs hammer the shape jaw into shape selectively in the corresponding jack of insertion activity nipper and fixing nipper.Workpiece is positioned in the jaw, shakes handle, movable nipper is moved to the inside, till jaw clamps workpiece.

Claims (2)

1, a kind of folding fitter's bench, form by folding stand and nipper, it is characterized in that: four pin 2 of folding stand are movably connected in respectively below the downward grooved crossbeam 1 of notch, put strut 3 and pole 4 between two pin under the same crossbeam, the pin of same position connects with the crosspiece 6 of double as tool rack on two crossbeams, screw rod 7 is arranged in the groove of crossbeam 1, nut 8, screw rod connects handle 9 in the groove end, extends bolt 11 on the nut, and the slotted hole 12 that bolt passes on the crossbeam is connected with carriage 13, carriage 10 is fastened on the crossbeam, the a pair of nipper 14 that a plurality of jacks 5 are arranged is fastened on respectively on carriage 13 and the carriage 10, and hammer shape jaw 15 inserts in the jack.
