Description
Technical field
The utility model is related to vehicle exhaust after-treatment device production technical fields, and in particular to a kind of welding fixture letter
Easy centering machine.
Background technology
Vehicle exhaust after-treatment device is the necessary device that current vehicle discharge meets laws and regulations requirement, and pipe fitting is welded as it
The important procedure of production.In the prior art, there are two kinds of situations for the welding positioning of pipe fitting：1st, fixture does not position, only
The positioning to pipe fitting is realized using the cooperation of workpiece；2nd, fixture positions pipe fitting using centering machine.
Described two situations all have deficiency, and if do not positioned, then pipe fitting and other workpiece gaps are uneven, are susceptible to void
The weld defects such as weldering, solder skip, burn-through；It is preferable using centering machine effect；Localization process is such as done, how complicated centering machine is,
And manufacture is of high cost, the cycle is also grown, and cost performance is not high.
Utility model content
The technical problems to be solved in the utility model is to have overcome the deficiencies of the prior art and provide a kind of welding fixture letter
Easy centering machine can quickly realize pipe fitting and other work pieces mate gap uniformities, so that firm welding is reliable, weld seam is beautiful
It sees, the weld defects such as no rosin joint, solder skip, burn-through；It is simple in structure, processing cost is low, the manufacturing cycle is short, the scope of application is big, cost
It is low.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of simple centering machine of welding fixture,
Including pedestal, positioning column, centering component and flange fixation kit；Positioning column is vertically fixed on pedestal, and centering component is arranged on
On positioning column, flange fixation kit is arranged on pedestal；The centering component includes outer barrel, centering ball and spring, the spring
It is fixed in outer barrel, the centering ball is arranged on one end of spring.
Further improved as the utility model, the flange fixation kit includes driving sliding block, driven sliding block, connection
Bar and positioning pin, the driven sliding block are linked together by connecting rod and driving sliding block, and the positioning pin is arranged on driven cunning
On block；The driving sliding block is arranged in the driving sliding slot of pedestal, and the driven sliding block is arranged in the driven sliding slot of pedestal.
Further improved as the utility model, the driven sliding block is equipped with positioning pin installation screw.
Further improved as the utility model, the driving sliding slot is deep gouge, and the driven sliding slot is straight slot.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
It can quickly realize pipe fitting and other work pieces mate gap uniformities, so that firm welding is reliable, weld seam is beautiful, nothing
The weld defects such as rosin joint, solder skip, burn-through；It is simple in structure, processing cost is low, the manufacturing cycle is short, the scope of application is big, at low cost.
