In upper Fig. 1-4:
The specific embodiment
Core of the present invention is to provide a kind of pipe fitting positioning device, and the positioning precision of this device is higher.Another core of the present invention is to provide a kind of bonding machine with above-mentioned pipe fitting positioning device.
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As in Figure 2-4, the pipe fitting positioning device that the embodiment of the present invention provides comprises location body 21 and reinforcing portion, and location body 21 is for clamping pipe fitting 31, and reinforcing portion is used to pipe fitting 31 to provide spacing more reliably.The shape that the end of location body 21 has ，Gai location division, location division is generally set to the structures such as semicircle or half elliptic according to the structure of pipe fitting 31, its inner surface forms the locating surface 211 coordinating with pipe fitting 31.Reinforcing portion is connected in the end of location division, and this reinforcing portion comprises and connects body 221 and be arranged at the elastic spacing one connecting on body 221.The critical component of the pipe fitting positioning device providing as the embodiment of the present invention, elastic spacing one can be shell fragment, and it can be at the radial expansion connecting on body 221 along locating surface 211, and its stroke can enter location division for pipe fitting 31.
When pipe fitting 31 is installed, pipe fitting 31 is pushed from the openend of location division, now pipe fitting 31 will contact with elastic spacing one and exert pressure to elastic spacing one, elastic spacing one retraction is connected in body 221, along with pipe fitting 31 constantly approaches the locating surface 211 on location division, the active force that pipe fitting 31 puts on elastic spacing one will reduce, now elastic spacing one will stretch out and connect body 221, when welding wire 41 acts on pipe fitting 31, elastic spacing one can limit pipe fitting 31 to the skew of the openend of location division, thus the location of realizing pipe fitting 31.
Known by foregoing description, than the content of introducing in background technology, the pipe fitting positioning device that the embodiment of the present invention provides has increased reinforcing portion, elastic spacing one in this reinforcing portion can effectively prevent that pipe fitting 31 is to the openend skew of location division, prevent that pipe fitting 31 and location division from departing from, with this, increase its positioning precision to pipe fitting 31, and then improved welding quality and the production efficiency of pipe fitting 31.
Further, in technical scheme, the reinforcing portion that the embodiment of the present invention provides is symmetrical arranged about the median plane of locating surface 211.So, after pipe fitting 31 coordinates with locating surface 211, the contact site of itself and reinforcing portion will increase to some extent, make the skew of pipe fitting 31 be subject to more restriction, thereby further increase the positioning precision of pipe fitting 31.
In order to optimize technique scheme, the embodiment of the present invention is replaced the structure of elastic spacing one, particularly, this elastic spacing one comprises thimble 222 and resilient sleeve, the end of thimble 222 can be taper, and this end exposes to and connects body 221 inner sides, and resilient sleeve is connected in thimble 222 and is connected between body 221 inwalls.Generally, the tube-like piece that resilient sleeve can adopt plastic cement to make, its one end is sheathed on the end of thimble 222, the other end directly with the inwall butt that is connected body 221.When pipe fitting 31 is during through thimble 222, thimble 222 by be subject to active force and under the driving of resilient sleeve along the radial expansion of locating surface 211, with this, reach the object of restriction pipe fitting 31.
Further, in technical scheme, above-mentioned reinforcing portion also comprises the regulating part 224 that can move along the flexible direction of thimble 222, and regulating part 224 is arranged between the inwall and resilient sleeve that connects body 221, particularly, regulating part 224 be connected body 221 interference fit.Now, the inwall of connection body 221 has a plurality of for locating the step surface of thimble 222 and regulating part 224, the socket of the end of one end of resilient sleeve and thimble 222, the front end socket of the other end and regulating part 224.For different occasions, thimble 222 is put on the size requirements of the active force of pipe fitting 31, only need to knock the afterbody of regulating part 224, adjust the distance of itself and thimble 222.
In the concrete process of implementing, above-mentioned regulating part 224 can be replaced with and is threaded by interference fit with the connected mode that is connected body 221, in the time need to adjusting thimble 222 and put on the amount of force of pipe fitting 31, turn regulating part 224, change it and screw in the length connecting in body 221.By contrast, when this connected mode can reduce to operate regulating part 224, its suffered external force, reduces the possibility that regulating part 224 is damaged then, and operation more for convenience.
On the basis of such scheme, also can be in the afterbody process operation hole of regulating part 224, this handle hole is suitable for adopting turning tool to drive regulating part 224 synchronously to rotate, and its shape can be square or rhombus etc.Obviously, this handle hole is more conducive to operating personnel and rotates regulating part 224, has further improved the location efficiency of pipe fitting 31 when simplifying the operation.Preferably, aforesaid operations hole is hexagon ring 225, and the power that operation tool is acted on handle hole distributes more equably, avoids handle hole to occur crackle, extends the service life of above-mentioned pipe fitting positioning device.
In preferred technical scheme, the end of above-mentioned thimble 222 also can be spherical structure, and this structure is more conducive to pipe fitting 31 and to thimble 222, applies active force reposefully, vibration when reduction pipe fitting 31 enters location division.In addition, the resilient sleeve described in such scheme is preferably spring 223, and in view of spring 223 has good elastic deformability, its stationarity in motion process is better, and can play more reliable position-limiting action to pipe fitting 31.
Certainly, the structure that above-described each embodiment provides can be combined in the situation that eliminating is conflicting, has reached better effect.
Bonding machine provided by the invention comprises wire feeder and the pipe fitting positioning device being oppositely arranged with wire feeder, and this pipe fitting positioning device is the described pipe fitting positioning device of above-mentioned arbitrary scheme.Because above-mentioned pipe fitting positioning device has above-mentioned technique effect, the bonding machine with this pipe fitting positioning device also should have corresponding technique effect, no longer describes in detail herein.
Above pipe fitting positioning device provided by the present invention and applied bonding machine thereof are described in detail.Applied specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
