The invention is intended to provide a kind of structure simple, step up effective, that production efficiency is high presser type floating clamp.
For achieving the above object, base case of the present invention is as follows: presser type floating clamp, comprises fixed mechanism and clamp system, and described fixed mechanism comprises stepped pedestal and the projection for clamping work pieces, described pedestal comprises top base and bottom base, and described projection is arranged on top base, described clamp system is arranged on bottom base, described clamp system comprises locating piece, for the clamping limb of clamping work pieces, for the pressing plate of clamping work pieces, for supporting the gripper shoe of pressing plate and passing pressing plate, gripper shoe is arranged at the bolt in locating piece, described clamping limb away from one end of clamping work pieces and bottom base hinged, described locating piece is fixedly connected with bottom base, the first hole and the second hole is provided with in described locating piece, described first hole is vertical with the second hole and communicate, the first push rod is provided with in described pressing plate, described first push rod is slidably connected in the first hole, the second push rod is provided with in described second hole, the end face that described first push rod and the second push rod offset is set to the conical surface matched, the other end of described second push rod is relative with clamping limb, described bolt sleeve is connected to nut, described nut is arranged at the top of pressing plate, spring part is provided with between described gripper shoe and locating piece.
The principle of base case and advantage: during operation, be first fixedly connected with locating piece with bottom base, and one end and the bottom base of clamping limb are hinged, and bolt is arranged in locating piece through pressing plate, gripper shoe; Then workpiece is positioned in projection, right-hand member and the top base of workpiece offset, tightening nuts presses down one end of pressing plate and workpiece offsets, first push rod moves down in the first hole simultaneously, conical surface one end that conical surface one end of first push rod extrudes the second push rod drives the second push rod to move right, second push rod crushing clamp gripping arm rotates around pin joint and one end of clamping limb and workpiece is offseted, and now spring part is impaction state; The clamping to workpiece is realized finally by one end of one end of pressing plate, clamping limb, projection and top base.When unscrewing nut, spring part promotes pressing plate and moves upward, and drive the first push rod to move upward, the second push rod unclamps clamping limb, makes one end of one end of platen clamp workpiece and clamping limb clamping work pieces all unclamp workpiece, can take out workpiece.This programme realizes the clamping to workpiece mainly through one end of one end of pressing plate, clamping limb, projection and top base, its overall structure is simple, and clamping effect is good, and workpiece is to add man-hour more stable, workpiece quality compliance rate after processing is increased, effectively raises production efficiency.
Preferred version one: based on the preferred version of scheme, described top base is connected with screw, by above-mentioned setting, screw is connected with the sidewall thread of top base, screw replaces the sidewall of top base to clamp workpiece, add the service life of pedestal, and screw is convenient for assembly and dismounting, has effectively saved cost.
Preferred version two: based on the another preferred version of scheme; described bolt is also socketed with packing ring; described packing ring is arranged between nut and pressing plate; by above-mentioned setting; packing ring has certain elasticity; the surface of pressing plate can be protected not to be subject to the wearing and tearing of nut, to add the service life of pressing plate, effectively save cost.
Preferred version three: based on the another preferred version of scheme, described spring part is stage clip, and by above-mentioned setting, stage clip has very strong compression capability, and when tightening nuts, gripper shoe extruding stage clip, makes stage clip be impaction state; When unscrewing nut, stage clip gives gripper shoe one to lifting force, saves time and manpower.
Preferred version four: based on the another preferred version of scheme, one end of described clamping limb by bearing pin and bottom base hinged, by above-mentioned setting, by above-mentioned setting, more stable when bearing pin makes clamping limb rotate around pin joint, and convenient for assembly and dismounting.
