The specific embodiment

At conventional grinding machine 1 shown in Fig. 1.This grinding machine provides the motor that is used for by grinding machine and drives the grinding stone 2 to be rotated.Grinding machine 1 provides the cylindrical shape support bar 3 that is called general supporter, and its rotating shaft with grinding stone 2 is parallel.The position that can adjust general supporter adapts to different purpose during with the grinding carrying out difference at grinding stone 2 the sword instrument is arranged.

Installation is used for the clamp 4 of straight flange instrument 5 to be used for laterally moving with rotation on the conventional supporter 3.Can be plane iron, firmer chisel and spokeshave by the example that grinding machine 1 comes grinding or sharpening and is attached at the instrument in the clamp 4.Be attached under the situation in the anchor clamps 4 at as directed instrument 5, instrument is engaged with grindstone 2 and it laterally moved on grinding stone by means of the anchor clamps 4 that can on general supporter 3, slide.

Conventional or known clamp have been shown in Fig. 2.These anchor clamps consist essentially of base 6 and clamp 7.

Base 6 have two legs 6 ', each provides the circular port 6 that is used on general supporter 3, being slidingly installed " (Fig. 3).With its side of leg 6 ' relative on, base provides two hold-down screws 8 (wherein, in Fig. 2, have only of the left side visible).The scotch 9 that is used to make instrument 5 to aim at is disposed in the either side of base 6, is clamp 7 slot millings between it.

Clamp 7 has two holes corresponding to screw 8.Screw knob 10 is attached to the screw 8 on clamp 7.Instrument 5 is abutted against scotch 9 and is placed between base 6 and the clamp 7, and can it be clamped to the fixed position by means of screw 8.In its flat machining side (being called face) or a side relative with the inclined-plane to the situation held instrument 5 of clamp 7, so that obtain grinding geometry shown in Figure 1.

In order to obtain accurate 90 ° of grindings of blade, adjoin clamp 7 instrument 5 face or in other words clamp 7 surface that is parallel to general supporter 3 and grinding stone 2 therefore be vital.The manual setting of two knobs 10 is depended in the position of clamp 7.Experience shows that the desired locations of clamp 7 is very difficult to obtain, and therefore, can't obtain accurate 90 ° of grindings of blade usually.For example tighten among Fig. 2 left handle knob 10 or with instrument 5 be very natural at a distance of the knob of certain distance (it is harder than of right side), cause the situation shown in Fig. 2, between base 6 and clamp 7, have angle α.Instrument 5 (it is parallel to clamp 7) therefore will be not parallel to grinding stone 2, cause being different from 90 ° tool point angle.

With reference now to the Fig. 4 that illustrates according to the clamp of the utility model.These anchor clamps have the chief component identical with conventional anchor clamps shown in Figure 2, i.e. base 15 and clamp 16.Clamp 16 has two fixing screws 17 to extend through the respective aperture in the base 15.Knob 18 and each screw 17 carry out that screw thread engages so that confirm the distance between base 15 and the clamp 16.Can be at each screw 17 arranged around compression spring 19 so that base 15 and clamp 16 be setovered separately.

Base 15 have two legs 15 ', each provides the circular hole of slidably installing 15 that is used on the general supporter 3 " (Fig. 5).

In its side in the face of general supporter 3, base provides the stayed surface that is preferably plane 15A.It is parallel with general supporter, and promptly two distance B equate.Abut against the situation held instrument 5 of this stayed surface 15A in its face relative with its inclined-plane or flat machine side, thus, instrument 5 is clipped on the appropriate location by floating holder 16, and is operated by knob 18.

Right side in Fig. 4, surperficial 15A finishes with the shoulder 15B in the base 15.This shoulder 15B is perpendicular to the longitudinal direction of base 15 with general supporter 3 therefore.

Use this design, will always come guiding tool 5 by base 15, its surperficial 15A and shoulder 15B be in the tram that is used for grinding (and therefore be used to obtain to expect 90 ° of tool point angles), and the position of Tube vice 16 is not how.This is shown in Fig. 4, and wherein, clamp 16 has no in the tram to instrument 5 under the situation of negative effect and forms angle β with susceptor surface 15A.

The positive characteristic of another of the utility model appears in the comparison between Fig. 3 and Fig. 5.Fig. 3 illustrates conventional anchor clamps, and wherein, the clamping surface of base 6 and clamp 7 is planes and parallel, this means, if instrument has as directed cone shape, then it is only clamped shown in arrow, causes more unsettled clamping.Reach as shown in Figure 5 on the other hand; In the anchor clamps according to the utility model, the clamping surface of clamp 16 can be that vertical inclined-plane is arranged, and this causes the clamping preferably of the conical instrument 5 of possibility; Indicated like arrow, the face of instrument carries out smooth contacting with susceptor surface 15A.

Shown in Fig. 1 according to another feature of the grinding machine of the utility model.In conventional grinding machine 1, clamp can freely slide along general supporter 3.The instrument 5 in the clamp 4 of this means can leave its grinding with grinding stone 2 and engage, and possibly cause the injury to operator's finger.

Yet,, can two safe scotch 20,21 be provided for general supporter 3 according to the utility model.The scotch 20 on the right side in Fig. 1 is fixed and can has the form of the screw in the screw thread axial hole in the end of general supporter 3.It is that the shoulder 15B that instrument 5 abuts against left side in the drawings has the fixed position with the reason that is fixed.Another scotch 21 in left side in the drawings is adjustable: can adjust its position on general supporter according to the width of instrument 5, the instrument that makes can not leave its grinding with grinding stone 2 and engage.Scotch 21 can have the form of screw operation clamp.
