Compared with the prior art, the tailstock has the beneficial effects that: 1) the disk spring is used for counteracting thermal expansion deformation caused by overheat of a workpiece during welding, so that the stretching amount of the tip of the tailstock is adjusted automatically, and the axial straightness of the welded workpiece is guaranteed; 2) the conductive rod and the incoming panel are in surface contact, so that a conductive area is increased, the conductive performance of the tailstock is improved, and the welding effect is further enhanced; and 3) due to the disk spring behind the incoming panel, the contact area of the incoming panel is increased; and when the incoming panel is abraded, a good conductive effect can also be kept.
Description
Technical field
The utility model relates to the automatic welding device field, the particularly a kind of tailstock that can offset axial thermal expansion automatically.
Background technology
At present in the Machine Manufacturing Technology on the automatic welding equipment during rotating welding axial workpiece; The tailstock centre mechanism of generally indiscriminately imitating engine lathe supports and holds out against; Only according to simple parameters such as the diameter of workpiece, length, according to lathe designing requirement design, it is no problem being made in like this on mechanical strength and the rigidity; But in welding process, workpiece is wanted expanded by heating (comprising the heat radiation to workpiece of thermal output and the external heat of welding gun).The tailstock structure of engine lathe has good self-lock ability, and the part of workpiece expanded by heating can't discharge, and shaft-like workpiece will occur bending and deformation.
Because the conduction problem is not considered in the design of the tailstock of general lathe class, tailstock centre contact area too small (some contact) so the electric conductivity from the workpiece to the tailstock is unsatisfactory, influences welding effect in addition.
Summary of the invention
The purpose of the utility model provides a kind of tailstock that can offset axial thermal expansion automatically, overcomes the deficiency on the prior art, solves the technical barrier that the distortion of workpiece expanded by heating can't be offset automatically on welding equipment, improves the electric conductivity of tailstock.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Can offset the tailstock of axial thermal expansion automatically; It is characterized in that comprise cylinder body, screw mandrel, screw, dish spring, incoming panel, fairlead, conducting rod and top, screw mandrel is located at the cylinder body afterbody; Screw mandrel is threaded with screw in the cylinder body; The dish spring is housed between screw and the fairlead, fairlead successively with incoming panel, conducting rod, top being connected, be provided with rotary sleeve between fairlead and the conducting rod.
Be provided with stage clip between said fairlead and the incoming panel.
The tailstock that can offset axial thermal expansion automatically that also has other a kind of structure; It is characterized in that; Comprise tailstock case, locating support, spring damping, locating support is arranged on the tailstock case rear side rail through positioning pressuring plate, is provided with spring damping between tailstock case and the locating support.
Compared with prior art, the beneficial effect of the utility model is: 1) utilize spring force automatically to offset that workpiece in the welding process is heated and the swollen distortion of rising of axial heat that produces, realized that the tailstock centre stroke adjusts automatically, guaranteed the surperficial glacing flatness of weldment.2) conducting rod is that face contacts with incoming panel, and the conductive area increase has improved workpiece at the fixing electric conductivity of tailstock, and then has improved welding effect.3) stage clip behind the incoming panel can also be strengthened the stressed of incoming panel contact-making surface, also can compensate automatically after the wearing and tearing, keeps the favorable conductive effect.

Among the figure: the top 12-tailstock of 1-cylinder body 2-handwheel 3-screw mandrel 4-screw 5-dish spring 6-stage clip 7-incoming panel 8-fairlead 9-rotary sleeve 10-conducting rod 11-housing 13-scroll wheel 14-locking pressure plate 15-locating support 16-spring damping 17-positioning pressuring plate
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Seeing Fig. 1, is tailstock embodiment one structural representation that the utility model can be offset axial thermal expansion automatically, comprises cylinder body 1, screw mandrel 3, screw 4, dish spring 5, incoming panel 7, fairlead 8, conducting rod 10 and top 11; Screw mandrel 3 is located at cylinder body 1 afterbody, and cylinder body 1 out screw rod 3 links to each other with handwheel 2, and screw mandrel 3 is threaded with screw 4 in the cylinder body 1; Be provided with dish spring 5 between screw 4 and the fairlead 8; Fairlead 8 is connected with stage clip 6, incoming panel 7, conducting rod 10, top 11 successively, and top 11 also can replace to chuck, are provided with rotary sleeve 9 between fairlead 8 and the conducting rod 10; Cylinder body 1 is located at the top of tailstock housing 12; Tailstock housing 12 lower ends are provided with scroll wheel 13, are linked to each other with the automatic welding device guide rail by locking pressure plate 14 during use, and tailstock housing 12 relies on scroll wheel 13 to support and move.
During card engaging workpiece; Rotation hand wheel 2 transmits and withstands workpiece through screw mandrel 3, screw 4, dish spring 5, fairlead 8, stage clip 6, incoming panel 7, conducting rod 10, top 11, in this process; Dish spring 5 receives force compresses with stage clip 6; Incoming panel 7 contacts well with conducting rod 10, has bigger contact area, effectively raises the electric conductivity of tailstock.In this process, electric current is transmitted to the source of welding current with electric current through cable through the binding post that is installed in incoming panel 7 at last from top 11 to conducting rod 10.
In welding process; Behind the workpiece expanded by heating; Expansive force transmits from top 11, conducting rod 10, incoming panel 7, stage clip 6, fairlead 8, dish spring 5, screw 4, because the latching characteristics of screw 4, so expansive force is mainly absorbed by the stress deformation of dish spring 5; Thereby realize the top stroke of adjustment automatically, offset the thermal expansion that workpiece is heated and produces axially.
See Fig. 2; The utility model also has other a kind of structure; Comprise tailstock case 12, locating support 15, spring damping 16, locating support 15 is arranged on tailstock case 12 rear side rail through positioning pressuring plate 17, is provided with spring damping 16 between tailstock case 12 and the locating support 15; Dish spring 5 is identical with stage clip 6 among the effect of spring damping 16 and the embodiment one, is used to offset the thermal expansion that workpiece is heated and produces axially.
