Abstract

The utility model relates to a fast clamping universal bench clamp. The drift bolts of a clamp seat pass through the straight long holes of an upper and a lower plates and the oblique long holes of a central disc. A handle on the edge of the central disc can drive the central disc to rotate, accordingly, the drift bolts and the clamp seat can move together to realize the purpose of clamping quickly. The utility model can quickly clamp the work piece with various shapes. Besides, the utility model has the advantages of simple structure, good manufacturability, low manufacturing cost and simple and convenient repair.

Description

Fast squeezing universal bench clamp

The utility model relates to a kind of bench vice, specifically a kind ofly can clamp fast, bench vice that can clamping different shape object.

The jaw of existing bench vice mostly is the plane, thereby produces difficulty for the clamping of garden shape, ellipse garden shape, asymmetric polygonal and irregular-shaped objects, promptly is difficult for stable holding, makes the gripped object body deformability again easily because of bite is too small.

Existing bench vice mostly is leading screw and regulates the jaw grip objects, when the jaw size is regulated significantly, can not finish clamping work fast, easily.

The purpose of this utility model is to provide a kind of bench vice of can the clamping different shape and clamping fast.

In the utility model, drift bolt under the pedestal passes the oblique slotted hole of straight slotted hole of upper and lower core and mid-game, the mid-game of changeing makes the lap position change of straight slotted hole with the oblique slotted hole of mid-game of upper and lower dish, thereby makes the drift bolt that slides in slotted hole and pedestal advance or move back to the bench vice center.

Concrete structure of the present utility model and function will further specify by example to closing accompanying drawing.

Fig. 1 is the utility model perspective view.

Fig. 2 is a plan structure schematic diagram of the present utility model.

Fig. 3 is a main TV structure schematic diagram of the present utility model.

In the accompanying drawings, the pincers seat 1 with jaw 2 is connected with drift bolt 17, and drift bolt 17 passes straight slotted hole 11, the oblique slotted hole 12 of mid-game 15 and the straight slotted hole 13 of lower wall 14 of dish 16.Pivot pin 18 is by the upper, middle and lower center hole, and nut 9 is spun on pivot pin 18 upper ends.Slip ring 8 can be enclosed within the lower wall outer rim with rotating freely, tooth bar 4 and blend stop 6 are housed on it, have a plurality of grades of grooves on the shelves bar 6, tooth bar 4 and worm gear 3 engagements that are installed on the lower wall, the handle 7 that connects by hinge 19 is installed on mid-game 15 edges, and handle 7 can be put into arbitrary grade of groove location on grade bar 6.Support 10 on the lower wall 14 is fixed on stylobate or the workbench.

In use, workpiece is placed on the jaw place, handle 7 is moved to the direction of needs, make mid-game 15 rotations, thereby change the lap position of the oblique slotted hole of the straight slotted hole of upper and lower dish and mid-game, thus changed the drift bolt 17 that can in slotted hole, slide and on the position of pincers seat 1, thereby clamp workpiece; And then, handle being placed in the shelves groove on the shelves bar 6 of handle below this moment, rotation worm gear crank 5 makes worm gear 3 drive tooth bars 4 and drives slip rings 8, further moves handle 7, clamping work pieces.

After work is finished, the shelves of handle 7 from shelves bar 6 are lifted in the groove, move, make upper, middle and lower dish and drift bolt towards the opposite direction motion during of pincers seat with the folder position to the direction of loosening, thus the relieving workpiece.

The oblique slotted hole of mid-game of the present utility model also can be bent tiltedly slotted hole.

The utility model can clamp the workpiece of various shapes fast, and simple in structure, and good manufacturability is keeped in repair easyly, and cost is low.

Claims

1, a kind of omnipotent fast clamping table vise, have jaw and pincers seat, it is characterized in that said omnipotent fast clamping table vise has the upper and lower dish that has straight slotted hole, have the mid-game of oblique slotted hole, pass the upper, middle and lower dish slotted hole heart and clamp a drift bolt that is connected and be installed in the handle that middle plate edge has, slip ring with tooth bar and shelves bar can freely rotate in the lower wall outer rim, tooth bar and the worm gear engagement that is installed in lower wall, and pivot pin is by the upper, middle and lower center hole.

2, according to the said omnipotent fast clamping table vise of claim 1, it is characterized in that the oblique slotted hole in the said mid-game can be straight tiltedly slotted hole, also can be bent tiltedly slotted hole.
