Description
Technical field
The invention belongs to Machining Technology field, be specifically related to clamp art during bar cutting processing.
Background technology
Cutting round metal bars, milling, boring etc. adds man-hour, and its clamping mode adopts two V-arrangement faces, two halves disc or three-jaw chuck clamping usually, and the manufacture craft of its clamping element is more complicated, and cost is too high, and handling comparatively bother.Especially for germanium, aluminium, this kind of light metal of tin, cutting force is less, and required clamping force is also very little, and during processing, handling are frequent, and thus require that clamp structure is simple, clamping and release are convenient, and traditional clamp structure can not adapt to the process requirements of this metalloid.
Summary of the invention
The object of the invention is the conventional brace structure Problems existing in order to solve light metal processing, and provide a kind of and can improve working (machining) efficiency and have the folder of certain protective role to enter device to clamping face.
The technical scheme realizing the object of the invention is as follows:
A kind of bar processing clamping device, include the L-type locating piece be installed on by screw on work top, to be arranged at the straight-arm of L-type locating piece other and be fixed on supporting seat on work top, screw rod that lower end is fixedly connected with supporting seat, be set on screw rod and be placed in spring in supporting seat, be set on screw rod and the bottom of indentation is plugged in clamp in supporting seat, is fitted to the nut of screw tip, described clamp top is inclined-plane by the side of L-type locating piece straight-arm, and the straight-arm of L-type locating piece and the inclined-plane of clamp coordinate clamping bar.
The present invention is equipped with soft ribbons on the inclined-plane of clamp.Described nut can be wing nut.Described spring can be butterfly spring.The horizontal arm of L-type locating piece is processed with mounting hole, and L-type locating piece is installed on work top through mounting hole by screw.The top of described supporting seat is the cylinder of band counterbore, and bottom is cuboid.Supporting seat is fixedly installed on work top by bolt.Inclined-plane on clamp and the contact point of bar are higher than the axle center of bar.
Bar work to be processed is clamped on work top by the straight-arm of L-type locating piece and the inclined-plane of clamp by the present invention, and L-type locating piece can change left and right adjusting according to bar diameter.By fastening nut, clamp overcomes the downward clamping work pieces of spring support force, and when unclamping nut, clamp under the action of the spring, moves up and leaves workpiece.Set spring can calculate its pressure as required more exactly, prevents excessively clamping the workpiece caused and scratches; The soft ribbons be arranged on clamp inclined-plane can protect surface of the work.
The present invention is simple and reasonable, easy and simple to handle, and processing and assembling need not Special Equipments, can greatly increase work efficiency.
Content of the present invention is set forth further below in conjunction with Figure of description.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, bar processing clamping device of the present invention, include the L-type locating piece 1 be installed on by screw 9 on work top 10, other and the supporting seat 8 be fixed on work top of the straight-arm being arranged at L-type locating piece, the screw rod 6 that lower end is fixedly connected with supporting seat 8, to be set on screw rod and the spring 7 be placed in supporting seat, be set on screw rod and the bottom of indentation and be plugged in clamp 5 in supporting seat, be fitted to the nut 4 of screw tip, described clamp 5 top is inclined-plane by the side of L-type locating piece straight-arm, this inclined-plane is equipped with soft ribbons 3, soft ribbons material can adopt nylon or tetrafluoro.With clamp 5 matched in clearance in the middle part of screw rod 6.The bar 2 that the straight-arm of L-type locating piece 1 and the inclined-plane of clamp 5 coordinate clamping to be processed.The horizontal arm of L-type locating piece 1 is processed with mounting hole, and L-type locating piece is installed on work top 10 through mounting hole by screw 9, can carry out the position of left and right adjusting L-type locating piece according to bar diameter change.For a collection of bar of same diameter, the position dimension of L-type locating piece is fixing.Described nut 4 can be wing nut, is convenient to manual operations, also can be other plain nuts, as six-sided nut, is beneficial to use torque spanner.Described spring 7 can use butterfly spring, and the pressure of disk spring is determined by its material, thickness and sheet number, can calculate its pressure more exactly as required, prevents excessively clamping the workpiece caused and scratches.The top of described supporting seat 8 is the cylinder of band counterbore, and bottom is cuboid.Supporting seat can adopt bolt to be fixedly installed on work top, also can fixedly be welded on work top.
During apparatus of the present invention work, bar 2 to be processed to be positioned on work top 10 and between the straight-arm being held on L-type locating piece and the inclined-plane of clamp, the inclined-plane of clamp and the contact point (bite) of bar higher than the axle center of bar, to guarantee stable holding.During fastening nut 4, clamp 5 overcomes spring support force and moves down clamping bar; When unclamping nut 4, clamp 5, under the effect of spring 7 restoring force, moves up and leaves bar.During handling bar, clamp 5 can rotate to an angle as required, is beneficial to quick despatch.
The present invention is verified in trial-production, test and trial production, successful.The present invention is specially adapted to the processing clamping of light metal bar, also may be used for the processing clamping of other materials bar.
