Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, the utility model provides a kind of hanging bar special fixture, comprises connecting plate 110, hanger connecting rod 120 and fixture 130.Connecting plate 110 is in horizontally disposed, and fixture 130 is fixed to connecting plate 110 by hanger connecting rod 120.Be fixed with multiple fixture 130 at a connecting plate 110, and described fixture 130 is evenly arranged along connecting plate 110 length direction, the axis of fixture 130 is vertical with described connecting plate 110 length direction.A connecting plate 110 is connected with many group fixtures 130, the multiple rod member to be clamped of clamping can be carried out simultaneously, be convenient to the operation of streamline, substantially increase production efficiency.
As shown in Figure 2, described fixture 130 comprises clamping body 131 and sleeve 132.As shown in Figure 6, clamping body 131 front end is provided with jaw 133, is provided with centre bore in the middle part of jaw 133, and rod member to be clamped is inserted into clamping body 131 from centre bore, is clamped by rod member to be clamped by described jaw 133.Sleeve 132 is arranged on outside described clamping body 131, and described sleeve 132 front end coordinates with the jaw 133 of described clamping body 131 front end, drives described jaw to apply or release clamping force.
As shown in Fig. 5 Fig. 6, in another embodiment, the manual special fixture of hanging bar also comprises clamping body connector 134, and described clamping body connector 134 one end is fixedly connected with described hanger connecting rod 120, and the other end is fixedly connected with described clamping body 131.Preferred as one, described clamping body connector 134 front end is provided with internal thread 135, the rear end of clamping body 131 is provided with external screw thread 136, described internal thread 135 and external screw thread 136 match, and are secured together by internal thread 135 and external screw thread 136 by clamping body 131 with clamping body connector 134.
In another embodiment, pass during described hanger connecting rod 120 one end is interior from the installing hole described connecting plate 110, and by nut 121, hanger connecting rod 120 and connecting plate 110 are fixed together, as shown in Figure 2.
As shown in Fig. 3, Fig. 4, Fig. 6, Fig. 7, in another embodiment, the jaw 133 of described clamping body 131 front end is arranged to the jaw of fFour piece type, namely by offering a criss-cross deep trouth on bottom surface, jaw is divided into equal-sized pintongs, and Excircle machining becomes the conical surface and through fine grinding process, makes it have good roughness.Circular hole is processed, for clamping rod member inside four jaws 133.Sleeve 132 front end is set to bellmouth 137, and the jaw 133 of taper matches with bellmouth 137, and bellmouth 137 is same through fine grinding process, thus improves the quality of fit of the jaw 133 of bellmouth 137 and taper.
Described sleeve 132 rear end is connected with described clamping body connector 134 by screw thread, and described sleeve 132 relatively clamping body 131 moves, backward for jaw 133 applies clamping force.
Preferred as one, described jaw 133 adopts elastic metallic material, can produce radial deformation under external force, can automatically reply original state when external force disappears, thus release clamping force.
During assembling, rod member to be clamped is inserted in the middle centre bore of jaw 133, load onto sleeve 132 threaded together clockwise simultaneously, sleeve 132 is moved backward relative to clamping body 131, now the bellmouth 137 of sleeve 132 front end coordinates with the jaw 133 of taper, jaw 133 is radially moved, implements to be fixedly clamped to rod member.Due to the latching characteristics of screw thread, this clamping force can not reduce automatically.
Only need the screw thread loosening sleeve 132 counterclockwise when needing to unclamp rod member, the radial forces that the conical surface produces disappears, and elasticity jaw 133 recovers distortion automatically, unclamps rod member to be clamped, now rod member to be clamped can be taken out.
For the rod member to be clamped of different-diameter, only need change clamping body 131 and the sleeve 132 of different size, namely respectively clamping body 131 and sleeve 132 are pulled down from clamping body connector 134, then change corresponding clamping body 131 and sleeve 132, make the diameter of diameter slightly larger than rod member to be clamped of the centre bore in the middle of clamping body 131.
The utility model structure is simple, and part is few, workable, can realize manual quick-clamping and unclamp, operating efficiency is high, for the clamping rod member of different-diameter, can change the clamping body of respective diameters, clamping body technique is simple, is easy to processing, suitable rod member mass operation.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
