Description
Technical field
This utility model belongs to Machining Technology field, is specifically related to clamp art during bar cutting processing.
Background technology
Round metal bars is cut, milling, boring etc. add man-hour, its clamping mode generally adopts two V-arrangement faces, two halves disc or three-jaw chuck clamping, and the processing technology of its clamping element is more complicated, and cost is too high, and loads and unloads cumbersome.Especially for germanium, aluminum, this kind of light metal of stannum, cutting force is less, and required clamping force is also only small, and during processing, handling are frequently, thus require that clamp structure is simple, and clamping and release are convenient, and traditional clamp structure does not adapt to the process requirements of this kind of metal.
Summary of the invention
The purpose of this utility model is the conventional brace structure Problems existing in order to solve light metal processing, and provides a kind of and can improve working (machining) efficiency and clamping face has the folder of certain protective role enter device.
The technical scheme realizing this utility model purpose is as follows:
A kind of bar processing clamping device, the straight-arm include the L-type locating piece being installed on work top by screw, being arranged at L-type locating piece is other and the screw rod being connected is fixed in the supporting seat that is fixed on work top, lower end with supporting seat, be set on screw rod to be placed in supporting seat spring, it is set on screw rod and the bottom of indentation is plugged in clamping block, be fitted to the nut of screw tip in supporting seat, described clamping block top is inclined-plane by the side of L-type locating piece straight-arm, and the inclined-plane of the straight-arm of L-type locating piece and clamping block coordinates clamping bar.
This utility model clamping block inclined-plane on equipped with soft ribbons.Described nut can be wing nut.Described spring can be butterfly spring.On the horizontal arm of L-type locating piece, processing has mounting hole, and L-type locating piece is installed on work top by screw through mounting hole.The top of described supporting seat is the cylinder with counterbore, and bottom is cuboid.Supporting seat can be bolted and be installed on work top.Clamp the contact point axle center higher than bar of the inclined-plane on block and bar.
Bar work to be processed is clamped on work top by the inclined-plane of the straight-arm of L-type locating piece and clamping block by this utility model, and L-type locating piece can change left and right adjusting according to bar diameter.By fastening nut, clamping block overcomes spring support force to clamp downwards workpiece, and when unclamping nut, clamping block under the action of the spring, moves upwardly off workpiece.Set spring can accurately calculate its pressure as required, it is prevented that excessively clamps the workpiece caused and scratches；The soft ribbons being arranged on clamping block inclined-plane can protect surface of the work.
This utility model is simple and reasonable, easy and simple to handle, and processing and assembling, without Special Equipment, are greatly improved work efficiency.
Of the present utility model content is expanded on further below in conjunction with Figure of description.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, bar of the present utility model processing clamping device, include the L-type locating piece 1 being installed on work top 10 by screw 9, the straight-arm side being arranged at L-type locating piece the supporting seat 8 being fixed on work top, the lower end screw rod 6 that be connected fixing with supporting seat 8, the spring 7 being set on screw rod to be placed in supporting seat, it is set on screw rod and clamping block 5 that the bottom of indentation is plugged in supporting seat, it is fitted to the nut 4 of screw tip, described clamping block 5 top is inclined-plane by the side of L-type locating piece straight-arm, equipped with soft ribbons 3 on this inclined-plane, soft ribbons material can adopt nylon or tetrafluoro.With clamping block 5 matched in clearance in the middle part of screw rod 6.The inclined-plane of the straight-arm of L-type locating piece 1 and clamping block 5 coordinates the bar 2 that clamping is to be processed.On the horizontal arm of L-type locating piece 1, processing has 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, it is simple to manual operations, it is possible to for other plain nuts, such 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 accurately calculate its pressure as required, it is prevented that excessively clamps the workpiece caused and scratches.The top of described supporting seat 8 is the cylinder with counterbore, and bottom is cuboid.Supporting seat can adopt bolt to be fixedly installed on work top, it is possible to fixes and is welded on work top.
During the work of this utility model device, bar 2 to be processed is positioned on work top 10 and is held between the straight-arm of L-type locating piece and the inclined-plane of clamping block, the inclined-plane of clamping block and the contact point (bite) of the bar axle center higher than bar, to guarantee stable holding.During fastening nut 4, clamping block 5 overcomes spring support force to move down clamping bar；When unclamping nut 4, clamping block 5, under spring 7 restoring force effect, moves upwardly off bar.During handling bar, clamping block 5 can rotate to an angle as required, is beneficial to quick despatch.
This utility model is verified in trial-production, test and trial production, and effect is obvious.This utility model is particularly well-suited to the processing clamping of light metal bar, it is also possible to the processing for other materials bar clamps.
