The specific embodiment

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

As shown in Figure 2, the disclosed a kind of boring anchor clamps of the utility model comprise base 1, supporting base 2, and described supporting base 2 is fixedly connected on the base 1, and its fixedly connected mode can be one of the forming, also can be for by bolt fixed mode etc.Wherein, these boring anchor clamps also comprise mandrel 3, bushing plate 8 and backing plate 7, and described mandrel 3 is fixed on the supporting base 2, and its fixedly connected mode can be one of the forming, and also can be mode of being threaded etc.In the figure present embodiment, with surely a mandrel dish 5 being arranged, this mandrel dish 5 has screw on the described mandrel 3, has on described supporting base 2 and the base 1 and the corresponding screw of the screw of mandrel dish 5, by bolt 6 three is fixed.

Also be fixed with a mandrel tube 4 on the mandrel 3 of described mandrel dish 5 upper ends.The center of described bushing plate 8 offers a mandrel hole 13, is provided with mandrel hole lining 14 in this mandrel hole 13, fixes with mandrel hole 13 interference fit.Described bushing plate 8 is sheathed on above-mentioned mandrel tube 4 movably by this mandrel hole 13.

And seeing also Fig. 4, its center of described backing plate 7 edge is to being outside equipped with an opening 19, mandrel 3 places that described backing plate 7 inserts the upper side that is arranged at described bushing plate 8 by this opening 19.In addition, mandrel 3 upper ends have one be threaded with mandrel 3 tighten parts 11, tighten parts 11 described backing plates 7 and bushing plate is limited on the mandrel 3 by this.The internal diameter in above-mentioned mandrel hole 13 is greater than the described maximum outside diameter of tightening parts 11; The internal diameter of above-mentioned mandrel hole lining 14 is greater than the described maximum outside diameter of tightening parts 11.In the present embodiment, the described parts 11 of tightening are preferably hexagon nut with flange.

Have at least one boring 15 on the described bushing plate 8, and seeing also Fig. 1 and Fig. 3, in the present embodiment, described boring 15 is preferably four, because the number of the boring 15 of processing work 20 required processing is four, so it is just enough to have four borings 15 on bushing plate 8.Simultaneously, in order to prevent that cutter causes damage to bushing plate 8 in the processing work process, in described four borings 15, all be provided with boring lining 16, with boring 15 interference fit.

As Fig. 2, Fig. 3 and shown in Figure 4, also have at least one support holes 10 on the described bushing plate 8, in the present embodiment, described support holes 10 is preferably four, in any one support holes internal thread connection or interference fit one supporting nail 9 is arranged, be preferably the connected mode of interference fit.The enlarged head of this supporting nail 9 is tightened described backing plate 7 and bushing plate 8 when being limited on the mandrel 3 tightening parts 11, bushing plate 8 is played certain supporting role, can not make bushing plate run-off the straight owing to unbalance stress, make simultaneously between bushing plate 8 and the workpiece 20 to keep certain clearance, making boring add the waste material that cuts man-hour can discharge from this gap smoothly.

Can also be fixed with a rhombus pin 17 on the described mandrel dish 5, insert with rhombus pin-and-hole 18 on the bushing plate 8 and cooperate, this rhombus pin 17 is used for fixing bushing plate 8, guarantees the location in a circumferential direction, installation site of bushing plate 8.

Described boring anchor clamps can also include an alignment pin 12, and described alignment pin 12 is inserted in the boring 15 of described bushing plate 8 movably.When after processing first screw on the processing work 20, the boring 15 that this alignment pin 12 inserts above-mentioned bushing plate, simultaneously, also be inserted in first hole on the processing work 20, so just, processing work 20 is played the effect of location, make between bushing plate 8 and the processing work 20 relative displacement can not occur, make machining accuracy more accurate.

Operation principle: as shown in figures 1 and 3, when clamping processing work 20, the parts 11 of tightening that will be threaded with mandrel 3 are earlier unscrewed a little and are got final product, the backing plate 7 that will have opening 19 takes off from mandrel 3, because the internal diameter of the mandrel hole lining 14 of described bushing plate 8 is greater than the described maximum outside diameter of tightening parts 11, this bushing plate 8 passes tightens parts 11 from mandrel 3 taking-ups.At this moment, processing work 20 is placed on the supporting base 2, this supporting base 2 just is embedded in the circular hole on the processing work 20, and processing work 20 is played positioning action.Then, bushing plate 8 is inserted on the mandrel tube 4 of mandrel 3, backing plate 7 is inserted in mandrel 3 places of the upper side of described bushing plate 8 by its opening 19, tighten after the parts 11, just can process bore operation by the boring on the bushing plate 8 15.When after processing first hole on the processing work 20, insert alignment pin 12 first hole on above-mentioned boring 15 and processing work 20, so just, processing work 20 is played the effect of location, make between bushing plate 8 and the processing work 20 relative displacement can not occur, make ensuing processing bore operation more accurate processing work 20.After finishing all processing boring work, in the time of need being discharged into processing work 20, only needing to tighten parts 11 unscrews a little and gets final product, backing plate 7 is taken off from its opening 19 of mandrel 3 upper edges, again bushing plate 8 is passed and tighten parts 11 from mandrel 3 taking-ups, at this moment, just can take off the workpiece 20 that processes from supporting base 2, entire work process is promptly finished.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
