Abstract
The invention provides a clamp for a square-section rod piece of an electric vehicle. The clamp comprises a bottom plate, a fixed clamping plate, a movable clamping plate, connecting shafts and a screw rod. The two ends of the fixed clamping plate, the two ends of the bottom plate and the two ends of the movable clamping plate are connected together in series through the connecting shafts respectively. The fixed clamping plate is fixed to the connecting shafts. The screw rod is connected with the movable clamping plate and can drive the movable clamping plate to move forwards or backwards relative to the fixed clamping plate, and thus a workpiece placed on the bottom plate is clamped by the fixed clamping plate and the movable clamping plate. The opposite faces of the fixed clamping plate and the movable clamping plate are provided with first V-shaped grooves, wherein the openings of the first V-shaped grooves of the fixed clamping plate are opposite to the openings of the first V-shaped grooves of the movable clamping plate. The included angle of each first V-shaped groove is 90 degrees. Cutting grooves are formed in the fixed clamping plate, the movable clamping plate and the bottom plate. Compared with the prior art, the V-shaped grooves are formed in the bottom plate and the clamping plates, so that the square workpiece has a larger stress area and smaller deformation when clamped.

Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present invention and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As Figure 1-5, the fixture of a kind of electric motor car square-section rod member, comprises base plate 1, strap 2, ambulatory splint 3, connecting axle 4, screw mandrel 5, baffle plate 6, Y shape transmission rod 7, first V-shaped groove 8, second V-shaped groove 9.The two ends of strap 2, base plate 1, ambulatory splint 3 have been horizontally disposed with through hole respectively perpendicular to the y direction of strap 2, base plate 1, ambulatory splint 3, strap 2, base plate 1, ambulatory splint 3 are set on two connecting axles 4 successively, to make the horizontal parallel setting successively of strap 2, base plate 1, ambulatory splint 3.Base plate 1 is longer than strap 2 and ambulatory splint 3.Strap 2 is fixed on the end of connecting axle 4.Base plate 1, ambulatory splint 3 can do advance relative to fixed base plate 2 or setback on connecting axle 4.Horizontally disposed Y shape transmission rod 7 comprises the first summit, the second summit, the 3rd summit, and wherein the first summit and the second summit are fixed on the outer wall of ambulatory splint 3, and the 3rd summit is connected with screw mandrel 5.Screw mandrel 5 drives ambulatory splint 3 to do advance relative to strap 2 or setback by Y shape transmission rod 7, realizes workpiece and to be fixed the object that clamping plate 2 and ambulatory splint 3 clamp.Y shape transmits bar 7 and the top power of screw mandrel 5 can be delivered on ambulatory splint 3 uniformly, make the chucking power of strap 2 and ambulatory splint 3 pairs of workpiece evenly, reduce the probability that is out of shape because local pressure is excessive of workpiece.Vertical and the base plate 1 of baffle plate 6 is arranged on base plate 1 in order to limit the processing length of workpiece.The first V-shaped groove 8 that strap 2 is relative with the opposite face of ambulatory splint 3 being provided with respectively opening.The angle of the first V-shaped groove 8 is 90 degree, to realize more firmly holding workpiece.
Certainly, because workpiece to be processed is square-section, because quadrangle is unstable, be easily out of shape in cutting process, the V-arrangement angle that can arrange second V-shaped groove 9, second V-shaped groove on base plate 1 is 90 degree.First V-shaped groove 8, second V-shaped groove staggers 90 degree of settings.
As shown in Figure 3, the centre position of strap 2, ambulatory splint 3 and base plate 1 is provided with cutting groove, to cut used.
In specific works, the screw mandrel 5 not front ambulatory splint 3 of work is in free state.First workpiece to be cut is placed on base plate 1, baffle plate 6 is withstood in one end, to determine Cutting Length, then screw mandrel 5 is started, by Y shape transmission rod 7, make the top power of screw mandrel 5 be delivered on ambulatory splint 3 uniformly, under the common cooperation of strap 2, base plate 1, ambulatory splint 3 and baffle plate 6, complete the location to workpiece and clamping.
As shown in Figure 2, when base plate 1 not being arranged the second V-shaped groove 9, when placing square section workpiece, first be placed in the first V-shaped groove 8 of strap 2 by square-section workpiece right-angle side, by coordinating of strap 2 and base plate 1, square shaped cross section is carried out spacing for the first time, and then start screw mandrel 5 ambulatory splint 3 is advanced, to make another right-angle side of square-section workpiece spacing by the first V-shaped groove 8 of ambulatory splint 3, so far, the holder for square-section workpiece completes.
As shown in Figure 1, when base plate is provided with the second V-shaped groove 9, so when placing square-section workpiece, should first by spacing in the second V-shaped groove 9 for workpiece right-angle side, then, after starting screw mandrel 5, the both sides straight flange of workpiece is spacing by the first V-shaped groove 8 of clamping plate 2 and ambulatory splint 3 respectively.Three-point fix is more firm.And cut from right angle, one, top, some incision is simply more convenient.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
