Abstract
The invention provides cold welding tongs with extreme eccentric jaw structures. The cold welding tongs comprise a tong seat, a fixed tong head, a movable tong head and a push shaft which is used for pushing the movable tong to move towards the fixed tong head, the tong seat is in a jaw shape, the opposite sidewalls in the jaw are respectively provided with the fixed tong head and the movable tong head coaxially, one side of the tong seat of the movable tong head is provided with a channel, and a drive end of the push shaft is arranged in the channel and is connected to the movable tong head. Jaws of the fixed tong head and movable tong head are both in extreme eccentric jaw structures. The cold welding tongs are capable of cutting off an exhausting pipe of an electronic component after evacuated exhausting is finished and allowing the residual tail to be extremely short, assembly of the electronic component is facilitated, appearance is attractive, and usage is more reasonable.
Description
Technical field
The invention belongs to cold welding tong field, relate in particular to a kind of cold welding tong of limit eccentric tongs mouth structure, this cold welding tong be mainly used in to exhaust nozzle, need the exhaust nozzle of the electronic device of vacuum exhaust to carry out the sealed-off pinch off (cold welding) of vacuum seal level.
Background technology
At present, there is a very large problem in conventional cold welding tong technology, is that the metal tail mouth after pinch off is oversize, in some cases such as for miniaturized electronic devices, this length is the installation that affects very much product, and not attractive in appearance, also unreliable, because oversize tail mouth is more easily damaged.
Causing the reason that tail mouth is grown is mainly because conventional cold welding tong binding clip is thicker, and jaw is (the non-eccentricity formula) that occupy center, but in actual application, binding clip must have enough thickness, can produce distortion otherwise binding clip is stressed, thereby cold welding effect can not ensure; The jaw of this layout placed in the middle, the tail mouth length after pinch off will be subject to the restriction of binding clip thickness, must be not less than the half of binding clip thickness, and binding clip is thicker, and this tail mouth length must be longer, and so the cold welding tong of current structure, tail mouth length cannot be accomplished the shortest.
Summary of the invention
The object of the present invention is to provide a kind of cold welding tong of limit eccentric tongs mouth structure, be intended to solve existing cold welding tong and process the longer problem of tail mouth residue after electronic device.
The present invention realizes like this, a kind of cold welding tong of limit eccentric tongs mouth structure, comprise clamp block, fixed pliers head, movable binding clip, for promoting the impeller-hub that described movable binding clip moves to fixed pliers head direction, described clamp block is tiger's jaw shape, on two relative direction sidewalls in described tiger's jaw, be respectively equipped with described fixed pliers head and movable binding clip, described clamp block is provided with the first side of adjustable clamp and is provided with passage, the drive end of the built-in impeller-hub of described passage, the drive end of described impeller-hub is connected with movable binding clip, the jaw of described fixed pliers head and movable binding clip is limit eccentric type shape and structure, so after pinch off, the residue tail mouth length of blast pipe can have nothing to do with clamp block thickness and be short to the limit.The core place of the eccentric jaw cold welding tong of the outstanding limit of the present invention that Here it is.
Preferably, the jaw of described fixed pliers head, movable binding clip is circular arc projection and is positioned at same plane, and the first sidewall of described fixed pliers head and adjustable clamp is all tangent with its jaw circular arc.
Than the shortcoming and defect of prior art, the present invention has following beneficial effect: the present invention can not be subject under self jaw body thickness affects, and the residue tail mouth that electronic device exhaust pipe clamp is had no progeny is short to the limit, has both facilitated the installation of electronic device, and shape is attractive in appearance, use more reliable.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figures 1 to 4, wherein, Fig. 1 is the top view of cold welding tong one embodiment of limit eccentric tongs mouth structure of the present invention; Fig. 2 is the lateral plan of the cold welding tong of limit eccentric tongs mouth structure in Fig. 1; Fig. 3 is the shape and structure view of fixed pliers head in Fig. 1; Fig. 4 is the shape and structure view of movable binding clip in Fig. 1.
A kind of cold welding tong of limit eccentric tongs mouth structure, comprise clamp block 1, fixed pliers head 2, movable binding clip 3, for promoting the impeller-hub 4 that described movable binding clip 3 moves to fixed pliers head 2 directions, described clamp block 1 is provided with tiger's jaw (omitting label in figure), on two relative direction sidewalls in described tiger's jaw, be respectively equipped with described fixed pliers head 2 and movable binding clip 3, described clamp block 1 is provided with movable binding clip 3 one sides and is provided with passage, the drive end of the built-in impeller-hub 4 of described passage, the drive end of described impeller-hub 4 is connected with movable binding clip 3, the equal limit eccentric setting of jaw of the jaw circular arc of described fixed pliers head 2 and movable binding clip 3.
More specifically, the jaw of described fixed pliers head 2, movable binding clip 3 is circular arc 21,31 projections and is positioned at same plane, and described fixed pliers head 2 one sidewalls 22 are tangent with its jaw circular arc 21, and described movable binding clip 3 one sidewalls 32 are tangent with its jaw circular arc 31.
In actual application of the present invention, by electronic device, (especially yardstick is very little, such as the electronic device 10 millimeters of magnitudes) blast pipe be placed between fixed pliers head 2 and movable binding clip 3, now, electronic device can abut on sidewall 32 and sidewall 22, the blast pipe of electronic device can farthest be deep between fixed pliers head 2 and movable binding clip 3, and can not be subject to the restriction of fixed pliers head 2 and movable binding clip 3 self thickness, drive after impeller-hub 4, by movable binding clip 3 to fixed pliers head 2 directions move and the most at last electronic device blast pipe cut off and automatically by hermetic cold welding of target exhaust pipe.The present invention can make the residue tail mouth after electronic device pinch off be short to the limit, has both facilitated the installation of electronic device, and attractive in appearance.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
