Abstract
The utility model relates to a hand-operated and automatic-opening self-locking positioning device and belongs to the technical field of tools. The self-locking positioning device comprises a hand-operated mechanism and an air-operated mechanism, wherein the air-operated mechanism comprises a single ejection rod air cylinder; a piston rod of the air cylinder is connected with a connector; a connecting rod in the air cylinder transversely penetrate through the connector; a hand-operated connecting rod mechanism adopts a handle, through which a first connecting rod and a second connecting rod are connected in sequence; the first connecting rod is fixedly connected to a support block through a first connecting rod pin; the second connecting rod is fixedly connected to the connecting block through a third connecting rod pin; the first connecting rod and the second connecting rod are connected through a second connecting rod pin; the handle is pulled to enable the force bearing points of the three connecting pins to be in the same straight line, so that self-locking of the device can be realized. The hand-operated and automatic-opening self-locking positioning device ensures the mounting precision of a workpiece and the quality of products; when the single ejection rod receives backward force, the piston rod drives the connecting rods to move backwards, so that the force bearing points of the three connecting pins are not in the same straight line to realize air-operated unlocking, the risk that workers' hands are clamped when assembling and disassembling the workpiece is avoided, the safety is improved, the operational procedures are simple, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of automatic locking positioning device that manually puts in place and automatically open, and it belongs to frock technical field.
Background technology
In domestic automobile gas extraction system frock, the location of workpiece is generally with using hand clamp or cylinder to connect locating piece at present; Using locating piece that hand clamp connects after welding completes, to need during workman's pickup each clamp of workman to go to open could pickup, and handling part is loaded down with trivial details, affects production efficiency; Use the locating piece that cylinder connects to have again the risk that clips to workman's hand when workpiece is installed, security is not high.
Summary of the invention
The problem existing in order to overcome prior art, the utility model provides a kind of automatic locking positioning device that can manually put in place and automatically open, this device adopts manual link mechanism and the pneumatic opening mechanism mode that combines, and makes workman when producing workpiece, enhances productivity and security.
The technical solution adopted in the utility model is: a kind of automatic locking positioning device that manually puts in place and automatically open, it comprises a man-operated mechanism and a pneumatic mechanism.Described pneumatic mechanism adopts a single rod cylinder, and the piston of single rod cylinder is connected with connector by piston rod, and connecting rod is horizontally through connector; Described man-operated mechanism connects first connecting rod by handle, described first connecting rod is fixed on back-up block by first connecting rod pin, first connecting rod is connected with second connecting rod by second connecting rod pin again, the upper end of second connecting rod is connected with contiguous block by third connecting rod pin, and the bottom of second connecting rod contacts with connecting rod inner side; The top and bottom of described contiguous block respectively connect an axle mobile in guide pin bushing and linear bearing, and the outer end of described axle is provided with baffle plate.
Described automatic locking positioning device is arranged on mechanism's connecting plate.
The beneficial effects of the utility model are: this automatic locking positioning device comprises man-operated mechanism and pneumatic mechanism.Pneumatic mechanism comprises a single rod cylinder, and its piston rod is connected with connector, and in connector, has connecting rod to be horizontally through.Man-operated mechanism adopts handle to connect successively first connecting rod and second connecting rod, and first connecting rod is fixedly attached to back-up block by first connecting rod pin, and the second contiguous block is fixedly attached to contiguous block by third connecting rod pin, connects between the two by second connecting rod pin.Pull handle makes first connecting rod pin, second connecting rod pin and 3 stress points of third connecting rod pin on same straight line, realizes the self-locking of this device.Guarantee the precision that workpiece is installed, guaranteed the quality of product.When single rod cylinder is received power backward, by piston rod, drive connecting rod to move backward, make first connecting rod pin, second connecting rod pin and 3 stress points of third connecting rod pin not on same straight line, and contiguous block is left need to determine bit position, realize pneumatic release.While making workman load and unload part, avoided clipping to the risk of workman's hand, improved security, and operation is simple, significantly improved production efficiency.

The specific embodiment
Fig. 1 and Fig. 2 show a kind of pair of guide rod self-locking cylinder device, and it comprises a man-operated mechanism and a pneumatic mechanism.Pneumatic mechanism adopts a single rod cylinder 14, and the piston 16 of single rod cylinder 14 is connected with connector 7 by piston rod 17, and connecting rod 8 is horizontally through connector 7.Man-operated mechanism connects first connecting rod 4 and the second connecting rod 5 by handle 3, first connecting rod 4 is fixed on back-up block 2 by first connecting rod pin, the upper end of second connecting rod 5 is connected with contiguous block 6 by third connecting rod pin 6a, first connecting rod 4 is connected by second connecting rod pin 5a with second connecting rod 5, and the bottom of second connecting rod 5 contacts with connecting rod 8 inner sides.The top and bottom of contiguous block 6 respectively connect an axle 10 mobile in guide pin bushing 12 and linear bearing 15, and its outer end is provided with for spacing baffle plate 11.
While adopting technique scheme work, the piston of single rod cylinder 14 is released, the piston rod 17 of single rod cylinder 14 is connected with connector 7, connector 7 is connected with connecting rod 8, connecting rod 8 is contacted with contiguous block 6, now make first connecting rod pin 4a, second connecting rod pin 5a and tri-stress points of third connecting rod pin 6a on same straight line, realize self-locking.At this process axis 10, play the effect of guiding.When single rod cylinder 14 is subject to power backward, pull connecting rod 8 to move backward, while first connecting rod pin 4a, second connecting rod pin 5a and tri-stress points of third connecting rod pin 6a being departed from be less than 180 ° on same straight line.Single rod cylinder 14 continues stressed, and connecting rod 8 is contacted with contiguous block 6, and contiguous block 6 is left need to determine bit position, to realize, open self-locking state.
