The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design, manufacturing is simple, easy to use, setting accuracy is high omnipotent blade processing positioning tool anchor clamps are provided.
The utility model addresses the above problem the technical scheme that is adopted: these omnipotent blade processing positioning tool anchor clamps comprise base plate, at least one hydraulic jack and at least two vanes fixed devices; Said hydraulic jack is fixed on the base plate; Said vanes fixed device comprises fixed head, strengthens gusset and at least one bracing or strutting arrangement; Said fixed head is fixed on the base plate; Said reinforcement gusset is fixed on the base plate, and said fixed head links to each other with the reinforcement gusset, and said bracing or strutting arrangement is installed on the fixed head.This use is novel because more than one hydraulic jack and more than one fixed head are arranged, and the position of support plate is different big or small to process on the position that can easily regulate hydraulic jack and the fixed head, difform blade.And hydraulic jack can hold on the very big blade of weight.
The said bracing or strutting arrangement of the utility model comprises gripper shoe and welding block, and welding block is fixed on the gripper shoe.Hydraulic jack is weldingly fixed on the base plate, and hydraulic jack can be regulated the blade of different height with the support different model, and is dismountable.The position that so can move hydraulic jack can adapt to the blade of different model.
The said fixed head of the utility model is provided with several draw-in grooves; Be provided with holddown groove in said each draw-in groove, this holddown groove is the groove structure, and said gripper shoe is provided with regulating tank; This regulating tank is a groove, and said gripper shoe is fixed on the fixed head through bolt cross-under regulating tank and holddown groove.Said bolt cross-under is in regulating tank and holddown groove.Adjustable gripper shoe can be slided in the holddown groove of fixed head, and blade slides in holddown groove so that with bolt back-up block is fixed on needed height through gripper shoe in process, so that welding block and blade welding are fixing.
At least be connected with one on the said fixed head of the utility model and strengthen gusset.Add that strengthening gusset can make fixed head more firm, reduce the vibrations of blade, help improving machining accuracy.It is more firm that fixed head is fixed on the base plate, can bear the pressure of omnipotent blade and the distortion in the process.
The utility model compared with prior art has the following advantages and effect: 1, gripper shoe can be free to slide in the fixed head holddown groove, can conveniently regulate the height of welding block, can process the blade of different model.2, the shape of draw-in groove and gripper shoe match, and are for gripper shoe can not move at left and right directions like this, reduce the vibrations of gripper shoe, improve machining accuracy.3, the holddown groove quantity on the fixed head can increase or reduce as required, can select to put into the combination of different fixed groove to gripper shoe, realizes the fixing of different blades or identical blade different gestures.4, jack can support blade, even make blade posture that also can keep under great stress in process constant.
Generally speaking, the utility model is simple in structure, easy for installation, applied widely.

Fig. 2 is the plan structure sketch map of Fig. 1.
Fig. 3 is the side-looking structural representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify, following examples are to the explanation of the utility model and the utility model is not limited to following examples.
Embodiment:
Referring to Fig. 1-Fig. 3; Omnipotent blade processing positioning tool anchor clamps in the present embodiment comprise base plate 1, four hydraulic jack 2 and three vanes fixed devices; The number of hydraulic jack 2 can be adjusted as required in the utility model; Generally the number of hydraulic jack 2 is at least one, and the number of vanes fixed device also can be adjusted as required, and generally the number of vanes fixed device is at least two.
The vanes fixed device comprises fixed head 5, bracing or strutting arrangement and reinforcement gusset 9; Bracing or strutting arrangement comprises gripper shoe 3 and welding block 4; Fixed head 5 is provided with nine draw-in grooves 8, is provided with holddown groove 6 in each draw-in groove 8, and this holddown groove 6 is the groove structure; On gripper shoe 3, be provided with regulating tank 10, this regulating tank 10 also is the groove structure.The number of draw-in groove 8 can be adjusted according to actual needs on the fixed head 5.Fixed head 6 is connected through bolt 7 with support plate 3.
Four hydraulic jack 2 are weldingly fixed on the base plate 1, and can dismantle, and change the position.Hydraulic jack 2 can be regulated height, to adapt to the blade of different model.Hydraulic jack 2 plays the supporting role to blade at device in the use, balance that can also adjusting vane.
