Abstract
The utility model provides a dual self-locking rapid clamp, which is used for solving the problems that the rapid clamp has low self-locking reliability and is inconvenient for remote operation. The dual self-locking rapid clamp has the technical scheme that the dual self-locking rapid clamp comprises a compressing rapid clamp mechanism, a locking rapid clamp mechanism and a base, wherein a driven piece of the locking rapid clamp mechanism is connected with a driving piece of the compressing rapid clamp mechanism; a pressure head is arranged on a driven piece of the compressing rapid clamp mechanism; an operating handle is arranged on a driving piece of the locking rapid clamp mechanism; and the compressing rapid clamp mechanism and the locking rapid clamp mechanism arrive at a dead point position at the same time. The dual self-locking rapid clamp has the advantages that the drawback of poor self-locking performance of the ordinary rapid clamp is eliminated, and the difficult problem of remote operation of the rapid clamp is solved; and since the operating handle is far away from a compressing point, the problem of interference with work pieces in the clamping process can be avoided. By adopting the improvement, the use reliability of the rapid clamp is improved, and the applied range of the rapid clamp is extended.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly two active grabs is connected, and the double self locking active grab in order to the locking workpiece belongs to the hand-operated tools technical field.
Background technology
Active grab, is especially using aspect welding tooling, check frock, the machining in machinery, automobile industry extensive use in a large number as a kind of manual quick clamping mechanism.Self-locking is realized in dead-centre position that active grab constitutes when utilizing four-bar linkage connecting rod and driven member conllinear, has simple in structurely, and characteristics such as be swift in motion.Though active grab has above-mentioned advantage, also have following problems: 1. self-locking reliability is relatively relatively poor, and is bigger in vibration, occurs easily when the working time is longer that mechanism breaks away from the dead-centre position and the phenomenon become flexible; 2. be subjected to the structural limitations of active grab, be not easy to carry out operated from a distance,, operate very difficultly, cause operating efficiency low when running into when barrier being arranged in the middle of remote-controlled operation or the clamped workpiece; 3. be subjected to the restriction of workpiece shape bigger,, workpiece interference problem in the operating process can occur if it is improper that the position is set.
The utility model content
The utility model is used to solve the defective of above-mentioned prior art and a kind of two active grabs connections that utilize is provided, and improves the double self locking active grab of self-locking stability.
The alleged problem of the utility model solves by the following technical programs:
A kind of double self locking active grab, its special feature is: comprise in the formation compressing active grab mechanism, locked active grab mechanism and pedestal, wherein locked active grab mechanism driven member connects through coupling assembling and compresses active grab mechanism driving link, compress on the active grab mechanism driven member pressure head is set, setting operation handle on the locked active grab driving link describedly compresses active grab mechanism and locked active grab mechanism arrives the dead-centre position simultaneously.
Above-mentioned double self locking active grab, described coupling assembling comprises rocking bar, connecting rod, and the rocking bar middle part is hinged with the bearing that is fixed on the pedestal, the hinged driving link that compresses active grab of rocking bar one end, other end articulated linkage, the hinged locked active grab driven member joint of the connecting rod other end.
Above-mentioned double self locking active grab, described locked active grab mechanism driven member is done rectilinear motion, is provided with between itself and the locked active grab driven member joint and adjusts screw rod and locking nut.
The utility model is low at existing active grab self-locking reliability, be not easy to remote-operated problem improves, with the ingenious connection of the active grab of two different structures, make latter two active grab of clamping work pieces reach the dead point simultaneously by the length of adjusting screw rod, thereby realize the order of double self locking.The utility model has been eliminated the drawback of common active grab self-locking performance difference, has solved the remote-operated difficult problem of active grab, because operating grip away from compressing a little, can be avoided the interference problem of clamping process and workpiece.Above-mentioned improvement has improved the dependability of active grab, has enlarged the range of application of active grab.

The specific embodiment
Referring to Fig. 1, Fig. 3, the utility model is made up of two active grabs and pedestal 11, wherein by compressing active grab mechanism driving link 13, compress active grab mechanism driven member 9, compressing active grab mechanism rod 12 and form the rectilinear active grab that compresses; Form plug-type locked active grab by locked active grab mechanism driving link 1, locked active grab mechanism driven member 3, locked active grab mechanism rod 2.By coupling assembling with locked active grab mechanism driven member 3 with compress active grab mechanism driving link 13 and be connected.Compress on the active grab mechanism driven member 9 pressure head 8 is set, pressure head 8 workpiece pressings 17.Setting operation handle 1-1 on the locked active grab driving link 1, shown position is the compacted state of workpiece, when workpiece is compacted, compresses active grab mechanism and locked active grab mechanism arrives the dead-centre position simultaneously.
Referring to Fig. 2, Fig. 4, described coupling assembling comprises rocking bar 10 and connecting rod 7, the rocking bar middle part is hinged with the bearing 18 that is fixed on the pedestal 11 by rocking bar bearing pin 15, the hinged driving link 13 that compresses active grab of rocking bar one end, other end articulated linkage 7, the other end of connecting rod 7 and locked active grab driven member joint 3-1 are hinged.Locked active grab mechanism driven member 3 is done rectilinear motion under the constraint of slide 4, be provided with between itself and the locked active grab driven member joint 3-1 and adjust screw rod 5 and locking nut 6, by regulating the connection length of adjusting screw rod 5, can make two active grabs reach the dead-centre position simultaneously, thereby realize the purpose of double self locking, adjust the position of screw rod 5 and adjust the back by locking nut 9 lockings, stable with maintaining body.As seen from Figure 4, it is hinged by driving link bearing pin 14 and contiguous block 16 to compress active grab mechanism driving link 13, and contiguous block and pedestal 11 are fixing.Driving link bearing pin 14 is concentric with rocking bar bearing pin 15, and is smooth and easy, laborsaving to guarantee operation.
Referring to Fig. 1-4, when the utility model uses, operating grip 1-1 turns clockwise, 3 actions of locked active grab mechanism driven member, through 10 actions of connecting rod 7 drive rocker, rocking bar 10 drives and compresses the active grab mechanism action, compresses the pressure head 8 that is provided with on the active grab mechanism driven member 9 workpiece 17 is compressed.When being rotated counterclockwise operating grip 1-1, workpiece is released.The utility model can be realized long-range workpiece pressing by operating grip 1-1.After workpiece was compacted, two active grabs all were in the dead-centre position, therefore can avoid breaking away from the phenomenon that become flexible the dead-centre position because of extraneous factors such as vibrations make active grab.
