Description
Technical field
The utility model relates to a kind of riveting device, and particularly a kind of energy uses the riveting device with the screw of any screw terminal.
Background technology
The current cap riveting tool that draws needs to arrange in pairs or groups " tooth rod (MANDREL) ", and then drawing cap clockwise twist lock on tooth rod, then user exerts all one's strength in instrument again and tooth rod is walked backward, reaches the object that riveted draws cap.The post-tensioning cap that riveted completes can be fixed on workpiece, needs inverse clock to turn tooth rod, to be separated tooth rod and to draw cap.Current market pull-up cap instrument all adopts special tooth rod, and that is each producer has the tooth rod design of oneself.Draw the screw thread specification of cap because tooth rod needs to coordinate, the tooth causing sometimes instrument to be arranged in pairs or groups rod be not suitable for user on hand draw cap.The most obvious example be exactly the instrument collocation of user be the tooth rod of metric system, but the cap that draws of user is screw thread specification made in Great Britain.If the fracture of tooth rod, user needs the tooth rod looking for former producer, and sometimes local importer is not stocked up.
Above situation is also a kind of trouble to producer, because screw thread specification is very many, tooth rod needs again to coordinate the screw thread specification of drawing cap, become can in stock with the problem of quantity when manufacturing.The terribly cold door of some specifications, may sell the tooth rod less than 50 these specifications for 10 years, but must produce in a large number when manufacturing.Sometimes user directly contact producer can inquire tooth rod, because freight charges and international remittance service charge problem, allows both sides perplex all very much and not calculate.There is pneumatic cap-drawing machine to have on the market and adopt existing screw as the way of tooth rod, but at present on the market interior hexagonal cylindrical head screw (Hexagon socket head cap screw) can only be used as tooth rod.As shown in Figure 1, the size of guide pin bushing 10 changes according to the diameter of screw 12.Lock member 14 be in order to allow screw 12 and the part in instrument do collective synchronization rotate required for.Manually drawing cap riveting tool, the wherein part that will be fixed in instrument of tooth rod, user rotates this part makes tooth rod do positive reverse rotation, and that is tooth rod and this part must synchronous rotaries.Because when using, also have rotating gripper rod that tooth rod is produced from drawing cap drawing cap to be first locked on tooth rod and after riveted.The pneumatic cap riveting tool that draws also is the same, and just this part is rotated by air motor.In order to prevent, screw 12 is freely independent to be rotated in design current on the market, adopts this way of lock member 14, but this has a very large trouble.First is that user can only use interior hexagonal cylindrical head screw as tooth rod.Second is the in different size of the hexagon ring of the interior hexagonal cylindrical head screw of each size.That is, the interior hexagonal cylindrical head screw of each size needs to arrange in pairs or groups the lock member 14 of oneself.If special lock member 14 cannot be provided, then specific interior hexagonal cylindrical head screw is had to use.
Therefore, the utility model, for above-mentioned puzzlement, proposes a kind of riveting device, to solve existing produced problem.

Detailed description of the invention
Refer to Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, riveting device of the present utility model comprises guide pin bushing 20, outer bush 22, clasp 24, driver 26, outer pillar 28 and an inner protective tube 30 in push rod 16, screw 18, wherein push rod 16 is metal pushrod, screw 18 is metal screws, using as tooth rod (MANDREL), the shape of this screw 18 is not limited, and interior guide pin bushing 20 is guide pin bushing in metal, outer bush 22 is metal outer bush, and clasp 24 is metal clasp.At this driver 26 for manual actuator, as hand handle, and be combined with each other fixing with interior guide pin bushing 20.Interior guide pin bushing 20 has the second space 34 of one first space 32 and second space 34, first space 32 circle segment be interconnected.The sidewall of the bar head of push rod 16 has the first screw thread, and the sidewall of second space 34 has the second screw thread, and push rod 16 utilizes the first screw thread and the second screw thread and interior guide pin bushing 20 to screw togather mutually, to be inserted in the first space 32 with second space 34.
The inner peripheral of one end of outer bush 22 has a first surface 36, and the other end is then arranged in the first space 32, and the second space 34 of circle segment, to be sheathed on interior guide pin bushing 20.Clasp 24 has second surface 38 and one the 3rd surface 40 be oppositely arranged.Clasp 24 is positioned at outer bush 22, to utilize second surface 38 near first surface 36, clasp 24 with its near one end of outer bush 22 be all arranged in the first space 32.Outer bush 22 plugs for screw 18 with clasp 24, and the screw body of this screw 18 exposes from outer bush 22, to draw cap 42 to screw togather with one.The screw terminal of screw 18 is arranged in the first space 32, and be close proximity between the 3rd surface 40 and push rod 16, and the end face of this screw terminal is provided with a groove 44, push rod 16 is inserted in groove 44, with near this screw terminal, and utilize push rod 16, clasp 24 and outer bush 22 fixed screw 18.In order to effectively prevent, screw 18 is independent to rotate, and for example, clasp 24 is designed to conical ring, but not as limit, first surface 36 is be first conical surface of gradually-reducing shape by the Inside To Outside of outer bush 22, and second surface 38 is second conical surface of the first corresponding conical surface, and the 3rd surface 40 is plane.When push rod 16 utilizes the first screw thread and the second screw thread and interior guide pin bushing 20 to screw togather mutually, screw 18 pushes away forward by push rod 16, when screw 18 pushes away forward, clasp 24 meeting clamping screw 18, because the gradient of second conical surface can diminish along the gradient of first conical surface, and clasp 24 is because the toughness of metal, can along gradient, screw 18 be pushed backward on the contrary, its principle is the same with collet chuck (collet).Push mutually because such and friction between metal, the part group making push rod 16, screw 18, interior guide pin bushing 20, outer bush 22 and clasp 24 form synchronous collective to operate.Because the utility model utilizes push rod 16, outer bush 22 and clasp 24 fixed screw 18, therefore the groove 44 of the screw terminal being subject to screw 18 can be avoided in size or restriction in shape, and the screw 18 with various screw terminal can be used.Driver 26 utilizes interior guide pin bushing 20 to drive interior guide pin bushing 20, push rod 16, outer bush 22, clasp 24, screw 18 synchronously to move forward and backward on driver 26 with drawing cap 42, draws cap 42 with riveted.
The part of outer pillar 28 is arranged in the first space 32, and to be sheathed on outer bush 22, and between outer bush 22 and interior guide pin bushing 20, outer pillar 28 worn by the screw of screw 18, and exposes from outer pillar 28.The part of inner protective tube 30 is sheathed on the madial wall of outer pillar 28, and inner protective tube 30 worn by screw 18, and exposes from inner protective tube 30, to screw togather with drawing cap 42.
The end face of the screw terminal of above-mentioned screw 18 can not be provided with groove yet, and this end face is a plane.As long as push rod 16 is near the end face of this screw terminal, and utilize push rod 16, clasp 24 and outer bush 22 fixed screw 18, do not need the appearance design of misgivings screw terminal.
Driver 26, except realizing with manual actuator, also can hydraulic type driver, electrodynamic type driver or pneumatic type driver realize.Refer to Fig. 8 and Fig. 9, its display is arranged on push rod 16, screw 18, interior guide pin bushing 20, outer bush 22 and clasp 24 on pneumatic type driver, in this, guide pin bushing 20 can present detachable combination with pneumatic type driver, therefore interior guide pin bushing 20 and push rod 16 all can be replaced.
In sum, the utility model utilizes interior guide pin bushing 20, clasp 24 and push rod 16 to fix screw 18, to avoid being subject to screw terminal restriction in shape.
