Description
Technical field
The utility model relates to a kind of automatic girth welding machine self-centering fixture.Belong to auto parts and components and make the field.
Background technology
The assembly shop can be found, dash weldering axle housing boxing stiffening ring, the boxing bonnet commissure phenomenon that leaks air, cause the reason of this kind situation to have by analysis: the diel wearing and tearing are excessive, cause the appearance and size at place, half shell Chinese lute hole less than normal, the stiffening ring cylindrical is greater than the appearance and size at place, axle housing Chinese lute hole, during the welding stiffening ring, cause mind-set axle housing limit skew in the welding, form the inclined to one side phenomenon of weldering, the self-centering fixture that the equipment that has carries only is applicable to welding 435 axle housings, there are not 457 axle housings, the self-centering fixture of 485 axle housings, the simple and easy pallet that the workshop is designed voluntarily is unreasonable because of locating, and often causes axle housing 360 degree rotations to change inclined to one side phenomenon, makes weld seam cause the inclined to one side phenomenon of weldering easily, reduced the welding performance of welding stiffening ring weld seam, made the commissure be easy to generate gas leakage.
Summary of the invention
At the deficiency of prior art, the utility model provides a kind of automatic girth welding machine self-centering fixture, has solved above-mentioned gas leakage and has welded problems such as inclined to one side.
Below introduce the utility model in detail, a kind of automatic girth welding machine self-centering fixture comprises the chassis, and described center chassis is provided with conical boss; Described conical boss is provided with the hydraulic pressure tensioning mechanism; Described chassis circumference is provided with some clamp mechanism, described clamp mechanism comprises end locating piece, locating piece one end of the described end connects deep groove ball bearing, described deep groove ball bearing is connected with conical boss, the end locating piece other end connects clamp, described clamp connects locating piece, and described locating piece connects the assist location piece; Described each locating piece is respectively equipped with two spring reference columns, and described spring reference column is provided with spring, and the described spring other end is connected on the spring reference column that is arranged on the chassis.
Optimize, described automatic girth welding machine self-centering fixture, described chassis and clamp mechanism position contacting are provided with gathering sill.
Optimize, described automatic girth welding machine self-centering fixture is connected by the bearing reference column between described deep groove ball bearing and the clamp mechanism.
Optimize, be connected by bolt between the described automatic girth welding machine self-centering fixture, described assist location piece and locating piece.
The utility model is the girth welding machine self-centering fixture, Design Orientation hole on the self-centering fixture of girth welding machine, welding 457, during 485 axle housing stiffening rings, by changing locating piece, realize the purpose of quick-clamping, after new anchor clamps are installed and used, promptly improved the replacing speed of anchor clamps, reduced the weld seam weldering again partially, the gas leakage problem is by improvements over the prior art, 435, under the 457 and 485 axle housing location dimensions variation situation greatly, by improving the self-centering fixture of design lathe, realize the raising of axle housing boxing stiffening ring operation welding quality, avoided the welding weldering partially, weld defects such as gas leakage have improved the replacing speed and the intensity of each axle housing anchor clamps.
