The above-mentioned device still includes: a shield.
Compared with the prior art, the utility model discloses a scheme has following advantage:
the movable support bracket is arranged to position and compress the rim, so that abnormal deformation of the rim can not occur in the welding process, the roundness of the rim is guaranteed, and the machining precision is improved.
Drawings
The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
fig. 1 is a schematic view of the overall structure of the present invention.
FIG. 2 is a cross-sectional view of the rim.
In the figure: 1. the welding machine comprises a welding machine, 2 parts of a horizontal pushing cylinder, 3 parts of a frame body, 4 parts of a bottom bearing platform, 5 parts of a side bearing platform, 6 parts of a supporting rod, 7 parts of a downward pressing cylinder, 8 parts of a downward pressing platform, 9 parts of a lifting cylinder and 10 parts of a wheel ring.
Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in figure 1, the utility model comprises a welding machine 1 arranged at the bottom, two supporting brackets arranged above the welding machine and a pressing mechanism fixed on the supporting brackets, wherein,
the two bearing brackets are opposite in position, one of the two bearing brackets is fixedly arranged, the outer side of the other bearing bracket is connected with a horizontal pushing cylinder 2, and the two bearing brackets are pushed by the horizontal pushing cylinder to move horizontally towards the fixedly arranged bearing brackets;
the supporting bracket comprises a bracket body 3, a bottom supporting platform 4 connected to the bottom end of the bracket body, and a side supporting platform 5 connected to the upper part of the bracket body;
the mechanism pushes down including connect in the bracing piece 6 of support body, connect in the air cylinder 7 that pushes down on bracing piece top and with the platform 8 that pushes down that the air cylinder expansion end is connected pushes down, the drive of pushing down the air cylinder push down the platform orientation the end bearing platform removes.
The support bar may be L shaped, with the bottom end of L shaped to connect to the bottom pallet and the top end of L shaped to connect to the top pallet.
For convenience of description, the support bracket fixedly disposed is hereinafter referred to as a first support bracket, and the bottom support table, the side support table, and the pressing table on the first support bracket are referred to as a first bottom support table, a first side support table, and a first pressing table, respectively. And recording a bearing bracket connected with the movable end of the horizontal pushing cylinder as a second bearing bracket, and recording a bottom bearing platform, a side bearing platform and a lower pressing platform on the second bearing bracket as a second bottom bearing platform, a second side bearing platform and a second lower pressing platform respectively.
The first pressing platform is opposite to the first bottom bearing platform in position, and the second pressing platform is opposite to the second bottom bearing platform in position, so that the pressing platform can be matched with the bottom bearing platform to press the lower part of the rim when pressing down.
The second bottom bearing platform, the second side bearing platform and the second pressing platform move along with the pushing of the horizontal pushing cylinder, so that the opening of the rim is extruded, and finally becomes a joint.
After the rim is placed, the two side bearing platforms can be respectively positioned at the positions of two sides of the rim which are inclined downwards.
Before welding, the translation cylinder drives the second support bracket to be far away from the first support bracket so as to put the rim 10 to be welded in, and in use, the bottom of the placed rim is contacted with the two bottom support platforms, the side surfaces of the placed rim are close to the two side support platforms, and the position of the welding seam of the rim is positioned between the two bottom support platforms. Then, the translation cylinder and the pressing cylinder move simultaneously, so that the second bearing bracket is close to the first bearing bracket, the two pressing tables press the inner side of the wheel rim and are matched with the bottom bearing table to press the lower part of the wheel rim, and the two side bearing tables act oppositely to press the two sides of the wheel rim to press the wheel rim.
After the whole rim is pressed, the joint of the rim is pressed and attached, and the welding machine can weld the joint. After the welding is finished, the translation cylinder and the pressing cylinder reset, and the welded rim can be conveniently taken out.
The utility model discloses in, the cross-section schematic diagram of the wheel rim of waiting to cut is shown in fig. 2, pushes down a bearing surface and a wheel rim internal surface shape and suits, end bearing platform with the bearing surface and the wheel rim external surface shape of side bearing platform suit to in compressing tightly the wheel rim.
And a lifting cylinder 9 is arranged on the lower side of the welding machine and used for driving the welding machine to lift. During welding, the welding machine can be driven by the lifting cylinder to move upwards, so that the welding gun can move to the position of the joint to be welded, and can be lowered after the welding is finished.
Optionally, a protective cover can be arranged to avoid splashing of welding slag in welding, and gas generated in welding can be collected to avoid pollution.
The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
