Description
Technical field
The utility model relates to the purifying vehicle exhaust field, the fixture while specifically referring to the prewelding clarifier.
Background technology
Ternary catalyzing unit, be mounted in most important outer purifier in automobile exhaust system, and the pernicious gases such as CO, the HC that it can be discharged vehicle exhaust and NOx change harmless carbon dioxide, water and nitrogen into by oxidation and reduction.Because this catalyst converter can be converted into innocuous substance by the harmful substances that mainly contains in waste gas simultaneously.Along with the harshness day by day of environmental protection requirement, increasing automobile has been installed exhaust gas catalytic converter and oxygen sensor device.It is arranged in the exhaust pipe of engine, and by redox reaction, carbon dioxide and nitrogen, therefore be referred to as again three-way catalytic converter.
The operations such as reel, loading, binding, reducing, welding are generally passed through in ternary catalyzing unit production.In the production of catalyst converter cylindrical case, most enterprises adopt steel plate are rolled into to tubular, and then the reducing processing is carried out in the shell two ends, operation in its whole operation is comparatively simple, but need large-scale apparatus to carry out reducing processing, the steel plate of reducing place is easy to break, and cost is higher; Minority enterprise adopts pre-Welding, but lacks effective clamping device, and working (machining) efficiency is not high.
The utility model content
The fixture of the utility model when the prewelding clarifier is set, the problem such as when solving traditional clarifier and manufacturing cost is higher, reach the purpose that improves welding efficiency, reduces costs.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises base, mast, supporting mechanism, arc bayonet socket, press mechanism, described base is connected with mast is vertical, supporting mechanism is arranged on base, the arc bayonet socket is arranged at the middle part of mast, the top of mast is provided with press mechanism, and the axial line of described supporting mechanism, arc bayonet socket and press mechanism overlaps.The semi-finished product steel plate that completes the reel operation is placed on base under the supporting role of supporting mechanism, by the arc bayonet socket on mast, is positioned, and under the fixation of last press mechanism, by manually starting welding, completes the manufacture of finished product clarifier shell.
Further, described supporting mechanism comprises support column and a plurality of gripper shoe, described a plurality of gripper shoe circular array formulas be distributed in support column around.The effect that is arranged on the middle support column of gripper shoe is that the semi-finished product steel plate of guiding reducing accurately is placed on welding position, and the gripper shoe of surrounding is fixing by steel plate itself, avoids being subjected to displacement and affecting welding effect when welding at the semi-finished product steel plate of reducing.
Further, described gripper shoe top also is provided with projection.The projection of gripper shoe bottom, play spacing effect, when welding, can bump with the semi-finished product steel plate of reducing unavoidably, and projection can be limited to the semi-finished product steel plate of reducing between gripper shoe and support column well, prevents that it is subjected to displacement.
Further, described press mechanism comprises down-pressed pole, cylindrical shell and handle, and cylindrical shell is fixed on mast top, and described down-pressed pole slides and is arranged in cylindrical shell, has chute on cylindrical shell, and described handle is connected with down-pressed pole through chute.When the semi-finished product steel plate of two ends reducing and middle steel plate reel welding, swinging handle moves down in chute, drives down-pressed pole and glides in cylindrical shell, and last down-pressed pole runs through whole clarifier shell and contacts with support column, then by manually carrying out last welding.
Further, as preferably, described chute is the S type.The chute of S type can make handle fix in upper and lower two positions, is convenient to moving up and down and fixing of down-pressed pole.
Further, as preferably, the material of described mast and base is cast iron.The mast of cast iron quality and base have higher intensity and larger weight, can effectively prevent during welding that it is subjected to displacement, and guarantee the stability of welding job.
The utility model compared with prior art, there is following advantage and beneficial effect:
1, the utility model comprises base, mast, supporting mechanism, arc bayonet socket, press mechanism, described base is connected with mast is vertical, supporting mechanism is arranged on base, the arc bayonet socket is arranged at the middle part of mast, the top of mast is provided with press mechanism, and the axial line of described supporting mechanism, arc bayonet socket and press mechanism overlaps.Only the semi-finished product steel plate after reel need be placed in supporting mechanism, in the time of can fast and effeciently be welded.
2, described chute of the present utility model is the S type, and the chute of S type can make handle fix in upper and lower two positions, is convenient to moving up and down and fixing of down-pressed pole.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, the parts title that Reference numeral is corresponding is as follows:
1-base, 2-mast, 3-gripper shoe, 4-support column, 5-projection, 6-arc bayonet socket, 7-down-pressed pole, 8-handle, 9-chute, 10-cylindrical shell.
The specific embodiment
Embodiment 1
As shown in Figure 1, the present embodiment comprises base 1, mast 2, supporting mechanism, arc bayonet socket 6, press mechanism, described base 1 is connected with mast 2 is vertical, supporting mechanism is arranged on base 1, arc bayonet socket 6 is arranged at the middle part of mast 2, the top of mast 2 is provided with press mechanism, and the axial line of described supporting mechanism, arc bayonet socket 6 and press mechanism overlaps.The semi-finished product steel plate that completes the reel operation is placed on base 1 under the supporting role of supporting mechanism, by the arc bayonet socket 6 on mast 2, is positioned, and under the fixation of last press mechanism, by manually starting welding, completes the manufacture of finished product clarifier shell.
