Description
Technical field
The utility model is related to a kind of wheel rims to process auxiliary equipment, specifically a kind of wheel rim welding hydraulic pressure separating formula
Welding fixture.
Background technology
Wheel rim main body is a kind of workpiece of tubular, and wheel rim main body is made of in the axial direction the splicing of three-stage structure part.Traditionally,
Usually all it is that welding forms one after needing to splice three-stage structure part well by the way of welding for wheel rim, it is existing
Wheel rim in the welding process, it is positioned without a kind of suitable mode, therefore can only be positioned using manual type, by
This brings the problems such as positioning accuracy is poor, cannot be guaranteed that three sections keep coaxial in welding in final welding process, in addition, also going out
Some positioners that welding positioning can be carried out to wheel rim are showed, but its structure design is unreasonable, holds in the welding process
Easily there is deformation, and operating process very complicated, operating pressure are big.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of welding positioning accuracy height, reliable welding quality, manufacturing procedures
Simple wheel rim welding hydraulic pressure separating formula welding fixture.
In order to solve the above-mentioned technical problem, wheel rim welding of the invention hydraulic pressure separating formula welding fixture is filled including driving
It puts, guider and the arc formwork for being pressed in wheel rim external peripheral surface, driving device include support base and support base
The hydraulic cylinder of upper fixed installation, guider are set including being both provided with fixed guide rail below hydraulic cylinder, fixing on guide rail
That puts is capable of the stent of the forepart fixed installation of the sliding block and sliding block of horizontal slip, the placement direction of fixed guide rail and hydraulic oil
The telescopic direction of cylinder is consistent, and the telescopic end of hydraulic cylinder is hinged on arc formwork, and stent is fixedly mounted on arc formwork.
It is provided with mounting hole in the middle part of the support base, the fixing end of the hydraulic cylinder is through passing through installation after mounting hole
Flange is fixedly mounted.
The pedestal of the support base is provided with bearing, and support base is installed by seat supports.
Spot welding preformed hole is placed on the arc formwork.
Dovetail groove is provided on the sliding block, the guide surface with dovetail groove cooperation is provided on the fixed guide rail.
After above-mentioned structure, due to the driving device of setting, guider and for being pressed in wheel rim outer circle weekly form
The arc formwork in face, flexible from there through hydraulic cylinder move back and forth arc formwork, at the same time so that guider into
Row is oriented to, and when reaching position to be welded, carries out spot welding splicing to wheel rim by the weld seam preformed hole on arc formwork, significantly
Welding positioning accuracy is improved, thus can ensure the concentricity of three sections of wheel rim, while reduces welding deformation, and alleviates work
People's operating pressure, and moving radially for arc formwork is driven by hydraulicdriven mode, i.e., suitable for various model wheel rims
Welding, and can realize automation, reduce artificial loss；Arc formwork has larger axial dimension, can wrap wheel
Three sections of rim ensure that the concentricity of three sections of wheel rim to be spliced, ensure that welding quality.
Description of the drawings
Fig. 1 is the stereoscopic-state structure diagram of wheel rim welding hydraulic pressure separating formula welding fixture of the present invention；
Fig. 2 is the main view status architecture schematic diagram of wheel rim welding hydraulic pressure separating formula welding fixture of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, to the present invention wheel rim welding hydraulic pressure separating formula welding fixture make into
One step is described in detail.
As shown in the figure, the wheel rim welding hydraulic pressure separating formula welding fixture of the present invention, including driving device 1, guider 2
And the arc formwork 3 for being pressed in wheel rim external peripheral surface, spot welding preformed hole is placed on arc formwork 3, and driving device 1 is wrapped
The hydraulic cylinder 5 being fixedly mounted on support base 4 and support base is included, wherein, the middle part of support base 4 is provided with mounting hole, hydraulic pressure
The fixing end of oil cylinder 5 is fixedly mounted after passing through mounting hole by mounting flange 9, it is possible thereby to not only so that positioning is reliable, and
Position of the hydraulic cylinder 5 in support base can be adjusted, meets the demand of adjusting, guider 2 is included under hydraulic cylinder
Side is both provided with fixed guide rail 6, fixes the forepart fixation peace for being capable of the horizontal sliding block 7 slided and sliding block set on guide rail 6
The stent 8 of dress, the placement direction of fixed guide rail 6 is consistent with the telescopic direction of hydraulic cylinder 5, and the telescopic end of hydraulic cylinder 5 is cut with scissors
It is connected on arc formwork 3, stent 8 is fixedly mounted on arc formwork 3.
Further, the pedestal of described support base 4 is provided with bearing 10, and support base 4 is supported by bearing 10 and installed, institute
Dovetail groove is provided on the sliding block 7 said, the guide surface with dovetail groove cooperation is provided on fixed guide rail 6, by dovetail groove and is led
It can be designed so that guide-localization is accurate to face, improve the reliability used.
At work, the hydraulic oil in hydraulic cylinder 5 is reduced so that the piston rod of hydraulic cylinder 5 resets, will be to be spliced
