Abstract
The utility model provides a clamping bolt of a workpiece clamp of a barrier-free rapidly clamping machine tool, aiming at providing a clamping bolt with simple structure and rapid and convenient mounting and dismounting. The clamping bolt is provided with a screw holder for connecting a screw rod; the width of positioning surfaces at two sides of a rectangular body of the screw holder is smaller than that of a T-shaped groove of a machine tool working table; the diagonals of the positioning surfaces at two sides of the screw holder are provided with circular arc chamfer angles; the rectangular body of the screw holder slides into the T-shaped groove of the machine tool working table and is fixedly locked into the T-shaped groove through 90-degree rotation of the circular arc chamfer angle. The clamping bolt of the workpiece clamp of the barrier-free rapidly clamping machine tool is mainly applied to the connection of T-shaped mounting grooves of machine tool equipment such as mechanical processing equipment, pressure equipment and the like; when the clamping bolt is used, the screw holder is put into any position of the T-shaped groove of the machine tool and then automatically locks after clockwise rotating for 90 degrees; when the clamping bolt releases, the whole pressure equipment can be directly taken out by rotating a screw cap for one lap and clockwise rotating the screw holder for 90 degrees; and the clamping bolt realizes rapid barrier-free mounting.
Description
Technical field
The utility model relates to a kind of securing member that the machine tool mounting groove fixes to clamp workpiece that is mainly used in.
Background technology
At present, be used for fastening bolt, usually by forming with the screw rod of above-mentioned T type groove shape, big or small essentially identical bolt block and connecting bolt seat by platen T type groove holding workpiece and pressing plate.Because its bolt block is consistent with platen T type groove size, before the installation, just can squeeze into T type groove with pressure device, during dismounting, remove smear removal interference in the T type groove, therefore to install, demounting procedure is loaded down with trivial details, labour intensity is big, inefficiency.
The utility model is the further improvement to above-mentioned prior art.
Summary of the invention
The purpose of this utility model is that the inefficient defective of clamping provides a kind of simple in structure, installing/dismounting fastening bolt quickly and easily at above-mentioned prior art dismounting inconvenience.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of fastening bolt of accessible quick clamping Machinetool workpiece anchor clamps, screw base with a connecting screw rod, it is characterized in that, the longitudinal length of screw base cuboid is less than or equal to the width of platen T type groove, on the diagonal of screw base two side-locating faces, be shaped on circular arc chamfering, the screw base cuboid slips in the platen T type groove, and 90 ° of rotations by above-mentioned circular arc chamfering are locked in the T type groove.
The present invention has following beneficial effect than prior art.
Easy to use, because it is very light that less than the throat width of platen T type groove, therefore install the screw base both sides, fast and efficient high, do not have interference region obstacle and interference region to hide stopping of face, turn 90 degrees around dextrorotation and can be automatically locked in the workbench T type groove.When dismounting.Only need screw pine one circle, the screw base counter-rotating just can all be removed whole pressure device for 90 °.
Description of drawings
Further specify the utility model below in conjunction with drawings and Examples.
Fig. 1 is the schematic top plan view of the utility model fastening bolt in platen T type groove is installed.
Fig. 2 is the utility model use principle schematic diagram.
The specific embodiment
Consult Fig. 1.The screw base 2 of connecting screw rod 1 is that both sides have locating surface 5, and longitudinal length is less than or equal to the cuboid of platen 7T type groove 3 width, rotates to be suitable so that it can do 90 ° along its length in platen T type groove 3.The transverse width of described cuboid is less than T type groove 3 width.Its transverse width can be slightly larger than or less than the width of platen T type notch 4, so both can enter from the notch of T type groove 3 terminations, also can during less than T type groove 3 notches, vertically enter T type groove 3, import platen 7T type groove 3 with convenient the slip at transverse width.For making things convenient for screw base 2 in above-mentioned T type groove 3 notches, to rotate and locking, on the diagonal of 2 liang of side-locating faces of screw base, be shaped on circular arc chamfering 6.Circular arc chamfering 6 on cuboid two side-locating faces 5 is help chamfering circular arcs along the diagonal angle rotation direction unanimity of a direction rotation.The cuboid of screw base 2 slips into or puts into the T type groove 3 of a workbench 7, and to half-twist, screw base 2 promptly is locked in the T type groove 3 laterally in the cavitys along the arc of diagonal angle chamfering circular arc.Also be shaped on the screwed hole step post 12 of connecting screw rod on the rectangle plane of screw base 2.Be rotation and the location that makes things convenient for fastening bolt, on polished rod outer round surface below the part that is threaded, be shaped on the annular knurl of convenient rotation.
Consult Fig. 2.Fastening bolt enters T type groove 3 by screw base 2 widths along the length direction of platen T type groove 3.Screw base 2 is put into lathe T type groove 3, and the cuboid termination of bolt screw seat 2 is slided into the appropriate location, then, turns clockwise by the direction of circular arc chamfering on the diagonal 6, can lock it in automatically in the T type groove 3.If the rotation direction of the circular arc chamfering on the diagonal 6 is counter-clockwise rotation directions, then can inhour revolve and turn 90 degrees, lock it in the T type groove 3.Screw rod 1 passes workpiece 8 pressing plates 9, by the screwed hole of centre connection of the screwed hole step post 12 on the screw base 2.Under its jack 11 effects, fastening by nut 10, just workpiece 8 can be clamped on the platen 7.When unclamping, only nut 10 need be revolved and turn around, screw base 2 is rotated counterclockwise 90 degree, just can directly unclamp whole grip device and workpiece.And, realize quick accessible installation and removal along T type groove 3 taking-up fastening bolts.Save the loaded down with trivial details step of conventional screw seat installation and removal, remove the pressure device of interfering.
