FIG. 1 is the structural schematic diagram of the utility model relates to an aluminum alloy is anchor clamps for precision finishing.

As shown in the figure: 1. the anti-slip device comprises a clamping plate, 2, an opening, 3, an anti-slip pin, 4, a spiral spring, 5, a base plate, 6, a consumable plate, 7, a pin sleeve, 8, a magnetic base, 9, an iron pin, 10 and a screw.

Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Example, see figure 1:

a clamp for precision machining of aluminum alloy comprises two oppositely-arranged clamping plates 1, wherein the two clamping plates 1 move relatively to clamp a workpiece between the two clamping plates 1, so that subsequent machining is carried out.

The clamping plate 1 comprises a base plate 5 and a consumable plate 6, the consumable plate 6 is detachably and fixedly arranged on the front end face of the base plate 5, a plurality of pin sleeves 7 are fixedly arranged on the periphery of the base plate 5, the four pin sleeves 7 are uniformly distributed on the periphery of the base plate 5, the center shafts of the pin sleeves 7 are parallel to the center shaft of the base plate 5, magnetic force seats 8 are fixedly arranged on the pin sleeves 7, the magnetic force seats 8 are fixedly arranged at the rear ends of the pin sleeves 7, the adsorption ends of the magnetic force seats face the interior of the pin sleeves 7, a plurality of iron pins 9 are fixedly arranged on the periphery of the consumable plate 6, the iron pins 9 correspond to the pin sleeves 7 one by one, the iron pins 9 are inserted into the pin sleeves 7 and matched with the magnetic force seats 8, the iron pins 9 are inserted into the pin sleeves 7, the rear ends of the iron pins are abutted to the adsorption ends of the magnetic force seats 8, the iron pins 9 are firmly adsorbed after the magnetic force seats 8 are opened, so that the rear end face of the consumable plate 6 is tightly attached to the front end face of the base plate 5, the time consuming plate 6 and the base plate 5 form a whole, namely the clamping plate 1, and the structure can avoid replacing the whole clamping plate 1 and reduce the use cost of the clamping plate 1.

The clamping surface of the clamping plate 1 is provided with a plurality of uniformly distributed open pores 2, when the clamping plate 1 is installed, the clamping plate 1 needs to be installed on a rotating shaft, the joint of the rotating shaft and the clamping plate 1 is positioned at the center of the clamping plate 1, the open pores 2 are uniformly distributed on the clamping plate 1 except the center to avoid the clamping plate 1 from being installed on the rotating shaft, the open pores 2 are arranged on the base plate 5 and penetrate through the consumable plate 6, the central axis of the open pores 2 is parallel to the central axis of the base plate 5, the open pores 2 are slidably inserted with the anti-slip pins 3, the length of the anti-slip pins 3 is smaller than the depth of the open pores 2 and can be integrally slid into the open pores 2, the spiral springs 4 are fixedly installed between the rear ends of the anti-slip pins 3 and the hole bottoms of the open pores 2, the open pores 2 penetrate through the base plate 5, the rear ends of the open pores 2 are threadedly provided with the screws 10, and the spiral springs 4 are fixedly installed between the screws 10 and the anti-slip pins 3, the front end of the antiskid pin 3 extends out of the open hole 2 through the spiral spring 4, the front end of the antiskid pin 3 is pushed out of the open hole 2 and extends out of the consumable plate 6 under the action of the spiral spring 4, the antiskid pin 3 retracts into the open hole 2 when pushed by a workpiece, at the moment, the spiral spring 4 is compressed, and the workpiece is abutted against the consumable plate 6.

When processing, at first through removing two splint 1 relative movement, until pressing from both sides the machined part tight, the machined part is at the tight in-process of clamp, and it conflicts the part on the splint 1 antiskid round pin 3, along with the removal of splint 1, this part antiskid round pin 3 then is pushed into corresponding trompil 2, and the antiskid round pin 3 that all the other are not contacted with the machined part then keeps stretching out the state, takes place to sideslip in the machined part course of working, and the antiskid round pin 3 that this part stretches out has then played the effect of blockking, avoids the machined part to break out from splint 1 and leads to equipment and personnel's damage.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto.
