Abstract
The utility model discloses a heavy rim welding jig. It includes the base and installs the supporting disk on the base, and have the lift cylinder of vertical setting on the base, the addendum cone is installed on lift cylinder's telescopic link top, is provided with radial guide way of arranging on the male cone (strobilus masculinus) of addendum cone, and the voltage -sharing has the gyro wheel in every guide way, and every gyro wheel is installed respectively on radial array's guide bar, and the guide bar can be radially flexible through the uide bushing of installing on the supporting disk, and the end of guide bar is installed to prop and is grabbed, props the outside terminal surface of grabbing and has the holding surface. After adopting foretell structure, make rim barrel three -section keep coaxial when the welding, concentricity when having guaranteed the welding has effectively improved vehicle operation balance quality, has reduced to move to carry and has strikeed, has improved life, not only make things convenient for the welding, made welding precision high moreover, do not needed to carry on again lathe work after welding simultaneously is good, optimized production processes, improved machining efficiency to the processing cost has been reduced.
Description
Technical field
This utility model relates to a kind of automobile component welding appurtenance, specifically a kind of heavy wheel rim weld jig.
Background technology
Wheel rim main body is the workpiece of a kind of tubular, wheel rim main body is made up of three-stage structure part in the axial direction, and for wheel rim main body, it is the most all that after needing to be spliced by three-stage structure part by the way of employing is welded well, welding forms one, but in splicing welding process, the most commonly used manual type positions, thus bring the problems such as positioning precision difference, it cannot be guaranteed that wheel rim circularity in welding process, the most also need lathe process to ensure dimensional accuracy, this processing mode is time-consuming, and the low precision of the wheel rim main body concentricity produced.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of heavy wheel rim weld jig of concentricity after can being accurately positioned and ensure to weld.
In order to solve above-mentioned technical problem, heavy wheel rim weld jig of the present utility model, including base and the support plate being arranged on base, there is on base the hoist cylinder being vertically arranged, the expansion link top of hoist cylinder is provided with addendum cone, the gathering sill of radial arrangement it is provided with on the male cone (strobilus masculinus) of addendum cone, roller all it is pressed with in each gathering sill, each roller is separately mounted on the guide post of arranged radially, guide post can be by being arranged on the fairlead radial expansion on a support plate, the end of guide post is provided with support and grabs, the supporting surface that the inner face shape of the wheel rim main body that the end face outside that support is grabbed is formed after having and splicing adapts.
Two fairleads it are separately installed with, the back-moving spring every guide post being all cased with between two fairleads on every described guide post.
Described support plate is arranged on base by column.
Being provided with pilot sleeve on the upper surface of described base, the expansion link of described hoist cylinder stretches out outside pilot sleeve.
After using above-mentioned structure, supportted, from the addendum cone of oil cylinder pushing and being provided with of coordinating with addendum cone, the guide post grabbed due to arrange, on the inner face of the wheel rim main body that thus can be formed after being supported on splicing by the supporting surface that support is grabbed in welding process, hydraulic oil cylinder driving addendum cone action is so that support grips in different azimuth and synchronizes to hold out against wheel rim main body, wheel rim cylinder three sections is made to keep coaxial when welding, ensure that concentricity during welding, it is effectively increased vehicle operation balance quality, reduce dynamic load impact, improve service life；Not only facilitate welding, and make welding precision high, need not after welding simultaneously is good carry out turnery processing again, optimize production process, improve working (machining) efficiency, thus reduce processing cost.

Fig. 1 is the cross-sectional view of this utility model heavy type wheel rim weld jig；
Fig. 2 is the plan structure schematic diagram of this utility model heavy type wheel rim weld jig；
Fig. 3 is the perspective view of single location support section in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, heavy wheel rim weld jig of the present utility model is described in further detail.
nullAs shown in the figure，Heavy wheel rim weld jig of the present utility model，Including base 1 and the support plate 2 being arranged on base，Propping up support plate 2 is to be arranged on base 1 by column 11，There is on base 1 hoist cylinder 3 being vertically arranged，On hoist cylinder 3, there is expansion link，The expansion link top of hoist cylinder 3 is provided with addendum cone 4，Pilot sleeve 12 is installed on the upper surface of base 1，The expansion link of hoist cylinder 3 stretches out outside pilot sleeve 12，The gathering sill 5 of radial arrangement it is provided with on the male cone (strobilus masculinus) of addendum cone 4，There is figure visible，Addendum cone top is the frustum of a cone，The V-shaped groove uniformly arranged in 12 roads it is uniformly provided with along generatrix direction on the frustum of a cone conical surface，Roller 6 all it is pressed with in each gathering sill 5，Each roller 6 is separately mounted on the guide post 7 of arranged radially，Guide post 7 is thus made to be contacted with the V-shaped groove of addendum cone by roller，Guide post 7 can be by being arranged on the fairlead radial expansion on a support plate 2，The end of guide post 7 is provided with support and grabs 8，Wheel rim main body is by superposed A section wheel rim，The B section wheel rim being positioned at middle part and the C section wheel rim being positioned at bottom are constituted，That is need A section wheel rim during welding、B section wheel rim and C section wheel rim weld，Support grab the end face outside of 8 have with splicing after the supporting surface 9 that adapts of inner face (at the wheel rim solder joint) shape of wheel rim main body that formed，During work, the two ends up and down of the supporting surface that support is grabbed tightly are propped up wheel rim and are treated inwall at boxing，Then under the effect of addendum cone and guide post, hold out against fixing welding.
Further, described guide post 7 being separately installed with two fairleads, two fairleads are arranged on a support plate, and every guide post is all cased with the back-moving spring 10 between two fairleads.
During use, when addendum cone moves upward under the driving of the expansion link of oil cylinder, and the guide post driving radially even distribution is protruding, thus reach the purpose held round；When addendum cone moves downward, guide post relies on action of reset spring power to regain.
