Preferably, the top of the base is provided with an installation groove, and the clamp is arranged in the installation groove; the clamp comprises a bearing seat, a rocker and a movable clamping piece; the two bearing blocks are arranged in the mounting groove, and the rocker is arranged in the middle of the bearing blocks; the rocker comprises a rotating handle and a bidirectional screw rod, and the rotating handle is connected with the bidirectional screw rod; the two ends of the bidirectional screw are respectively provided with a movable clamping piece, and the middle of each movable clamping piece is provided with a thread corresponding to the bidirectional screw.
Preferably, sliding grooves are formed in two side edges of the mounting groove; the two ends of the movable clamping piece are provided with positioning sliding blocks, and the positioning sliding blocks extend into the sliding grooves.
Preferably, the bearing seat is fixed in the mounting groove by screws.
Preferably, the top of the base is provided with a plurality of first positioning holes distributed on two sides of the clamping device.
The using process of the utility model is as follows:
firstly, the base is fixed on a machine tool through bolts.
And secondly, punching a positioning hole at the specified position of the blank, putting the positioning pin into the first positioning hole, and putting the blank on the base so that the positioning pin enters the positioning hole of the blank.
And thirdly, shaking the rotating handle to drive the bidirectional screw to rotate, so that the two movable clamping pieces move towards the middle until the blank is clamped tightly, and fixing the x axis and the y axis of the blank on a plane is completed.
And fourthly, machining the blank at the upper part by utilizing a machining tool to manufacture the formed part.
And fifthly, reversely shaking the rotating handle to enable the movable clamping piece to move towards two sides and then taking out the part.
In the second step, blanks with different lengths can be positioned by using first positioning holes at different positions, and the longer blank is positioned by using a positioning hole which is farther away from the clamping device; the locating pin is fixed with pressing from both sides the dress with the blank, forms a triangle-shaped on the plane, and the locating pin is put into more far away first locating hole and just can be guaranteed that the area of triangle-shaped is big more, and is fixed more firmly.
The utility model has the beneficial effects that: the blank only needs to beat a locating hole, the cooperation locating pin is fixed a position the blank, carry on spacingly to blank x axle direction simultaneously again on the plane, the first movable clamp plate of rethread carries out the centre gripping with the second movable clamp plate to the blank, carry on spacingly to blank y axle direction on the plane, accomplish the fixed of blank, can process the blank, need not the processing machinery of high accuracy and beat the locating hole in a plurality of positions, the processing cost is reduced, and the process time of blank earlier stage has been reduced, the production efficiency is improved.
