Accompanying drawing explanation
Fig. 1 is the front section view of the present invention.
Fig. 2 be the pilot pin group quantity of the present invention be the pilot pin group structure chart during situation of three.
Fig. 3 be the pilot pin group quantity of the present invention be the pilot pin group structure chart during situation of two.
Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2, Fig. 3, connected mode and the detailed description of the invention of the present invention are illustrated, the invention is not restricted to following this kind of connected mode and detailed description of the invention.
Below in conjunction with Fig. 1, the connected mode of the present invention is illustrated.
A kind of for connecting rod and the accurate positioning device of shell part, including positioning sleeve device, hydraulic means, set inner driver, pilot pin device, described set inner driver one end is connected with pilot pin device, and the other end is connected with hydraulic means through rear from positioning sleeve device inside.
Positioning sleeve device includes that positioning sleeve 11 and guide 12, described positioning sleeve 11 are arranged on outside guide 12, and guide is between set inner driver and positioning sleeve.Positioning sleeve outer surface can arrange cylindrical seam, is used for positioning with clamp body etc..Meanwhile, the length of positioning sleeve 11 and guide 12 can be adjusted as required, such as the most fixing pilot pin device, can install the positioning sleeve 11 of lengthening, is arranged on positioning sleeve 11 by pilot pin device.
Hydraulic means includes that oil cylinder 21, piston rod, oil path block 23, described piston rod are connected with set inner driver.In the present embodiment, piston rod is directly connected with the blind rivet on set inner driver.
Set inner driver includes pull bar 31 and blind rivet 32, and on described pull bar 31, there is T-slot the one end near hydraulic means, and T-slot is connected with hydraulic means built with blind rivet, blind rivet;Equally distributed dovetail oblique groove is had on the other end of pull bar;In the present embodiment, blind rivet is directly connected with the piston rod of hydraulic means.
Pilot pin device includes the most equally distributed multiple pilot pin group 41, and each pilot pin group includes pilot pin 411, set screw 412;One end, side of described pilot pin 411 is the oblique tongue of dovetail, and shape size is consistent with dovetail oblique groove, and the inner opposite end of pilot pin extends to overlap the axle center of inner driver;Having flat screw thread on the lateral ends of pilot pin, set screw is arranged on flat screw thread.Location plane described in the present embodiment refers in particular to organize the circular flat at pilot pin group place more, and this plane is with pull bar central point as the center of circle, and the plane that plane is vertical with pull bar edge, pilot pin is connected to edge from the center of circle.At this under design, when the oblique tongue of dovetail on pilot pin is combined with the dovetail oblique groove on pull bar, the up and down motion of pull bar can be transformed into the reciprocating motion of pilot pin, i.e. pull bar and move upward, and pilot pin is protruding;Pull bar moves downward, and pilot pin is inwardly retracted.
The quantity of pilot pin group 41 can be set to two groups or three groups.When being set to three groups, being equivalent to the straight pin of routine, alternative straight pin uses;When being set to two groups, being equivalent to the rhombus pin of routine, alternative rhombus pin uses.
In pilot pin group 41 can mounting and adjusting circle 414, can be fixed on flat screw thread.Adjust circle and can be utilized for fine setting, it is ensured that set screw is consistent to the location planar central point i.e. distance of pull bar centrage.
Also can install guide pin bushing in pilot pin group additional, guide pin bushing needs to be fixed on the outside of pilot pin, in i.e. pilot pin is arranged on guide pin bushing.Guide pin bushing play fixing pilot pin position, it is to avoid long-time use pilot pin after produce deviation.
Can install guide cover 42 on pilot pin device, guide cover 42 is positioned at the top of pilot pin device.Guide cover can make to be screwed, and plays guide function during clamping workpiece, prevents various chip from entering into inside positioner simultaneously.
During work, form location with the cylinder seam on positioning sleeve and clamp body, then rely on oil cylinder to control hydraulic pressure and control the up and down motion of pull bar, thus control the flexible of pilot pin and workpiece is positioned.When the quantity of pilot pin group is three groups, using method is identical with straight pin;When the quantity of pilot pin group is two groups, using method is identical with rhombus pin.
