The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment is shown in Fig. 1-11: a kind of 4 balance positioning clamping devices that are used for processing automobile clutch bonnet, side at frock base plate 1 is provided with the first stationary positioned seat A and hold down gag 5 and second stationary positioned seat B and with it the supporting hold down gag 5 supporting with it, have the bearing 2 of groove structure in the opposite side setting of frock base plate 1, balance weight 4 be arranged in bearing 2 groove and with groove movingly.One end of bearing 2 is provided with coaxial circular hole 10 and screw 11, and circular hole 10 and screw 11 total center lines are parallel to frock base plate 1; The other end of bearing 2 is provided with and bearing pin 9 through hole 12 movingly, and the center line of described through hole 12 and described circular hole 10 and screw 11 total center lines are parallel to frock base plate 1 and contour with frock base plate 1; Sleeve 8 is installed in the circular hole 10 movingly.One end of balance weight 4 is provided with and bolt 3 waist hole 7 movingly, and the other end of balance weight 4 is provided with and bearing pin 9 pin shaft hole 6 movingly; Lateral aperture between waist hole 7 and the pin shaft hole 6 equates apart from P with lateral aperture between screw 11 and the through hole 12 apart from L.Bearing pin 9 inserts in through hole 12 and the pin shaft hole 6, and bolt 3 inserts in sleeve 8 and the waist hole 7, the screw thread of the termination of bolt 3 and screw 11 engagements.The described first stationary positioned seat A or the second stationary positioned seat B are vertically welded on the frock base plate 1, and described bearing 2 is fixed on the frock base plate 1 by the bolt perpendicular positioning; Tighted a bolt 3 o'clock, bolt hexagonal end face promotes sleeve 8 and clamps balance weight 4.
After described bearing 2, sleeve 8 and balance weight 4 assembled by bolt 3 and bearing pin 9, the plane of balance weight 4 one sides upper end was the 3rd positioning seat C, and the plane of balance weight 4 opposite sides upper end is the 4th positioning seat D; The outside of the 3rd positioning seat C or the 4th positioning seat D is provided with hold down gag 5.
One side of automobile clutch bonnet is by first contour stationary positioned seat A and second stationary positioned seat B supporting, and opposite side is by the 3rd positioning seat C and the 4th positioning seat D supporting that are positioned on the balance weight 4.When hold down gag 5 compresses, if the blank anchor point on the workpiece has height error (to be generally 0.1～0.5mm), because balance weight 4 can be around 9 swings of the bearing pin in the bearing 2, the 3rd positioning seat C and the 4th positioning seat D can be close to the blank anchor point that is stamped height error behind the automobile clutch automatically, realize four anchor points of automobile clutch bonnet are compressed from dynamic(al) correction; Accurate positioning, reliable clamping.Anchor point A, the B of 4 balance positioning clamping devices, C, 4 height with respect to the frock base plate of D are corresponding with part to be processed respectively, after the adjustment, lock-screw 3, to reach 4 applyings of A ', B ', C ', D ' that anchor point A, B, C, D contact with part to be processed, avoid wherein any point to cross the location and produce the gap; Last rotation manual reversal valve, the corner cylinder of hold down gag 5 drives the pressing plate clamping work pieces; Because part to be processed A ', B ', 4 of C ', D ' locate under nature, the pressing plate clamping force can not cause the part to be processed distortion.The baseplane flatness of automobile clutch bonnet reaches 0.03～0.04mm, meets the specification requirement flatness 0.05 of workpiece fully, and each PRECISION HOLE aperture size and position degree thereof all can meet the requirements of technical conditions.
