Description

TECHNICAL FIELD

[0001] The utility model belongs to the rim, spoke processing technical field especially relates to a rim, spoke welding device. BACKGROUND

[0002] The rim and spoke are the core mechanism of the whole structure of the hub, specifically, the spoke is located at the center of the hub, and the rim is welded on the spoke. The rim with a cylindrical structure is supported by the spoke to maintain stable load bearing of the vehicle during the working process.

[0003] The spoke has a plurality of spoke arms welded on the inner side wall of the rim, so during the welding process, the spoke arms on the spoke need to be fully welded to the rim. The common hub for tires on the market often has five spoke arms.

[0004] Therefore, each spoke arm needs to be welded to the rim during the welding process. In the actual welding process, the current welding method is to weld each spoke arm to the hub of the tire by using a single welding gun. The disadvantage of this welding method is that due to the one-by-one welding of the spoke arms, the connection strength of each spoke arm welded to the rim is different due to the stress of the material after welding, that is, the separate welding of the spoke arms easily leads to uneven stress after welding.

[0005] Therefore, all spoke arms need to be welded synchronously during the actual working process, and the existing welding device cannot perform synchronous welding. In the actual working process, synchronous welding can only be performed by multiple operators.

[0006] This welding method not only has low efficiency, but also has high labor cost for welding the spoke and the rim.

[0007] Therefore, during the actual working process, if an automatic welding device is used to synchronously weld all spoke arms of the spoke to the rim, not only the welding efficiency is greatly improved, but also the connection strength of all spoke arms after welding is uniform due to the automatic synchronous welding method, and the quality of the spoke welding is greatly improved.

[0044] Example 1

[0045] like Figures 1-5 As shown, a rim and spoke welding device includes a welding mechanism 24, which improves the welding mechanism 24 to enable the simultaneous welding of multiple spoke arms on the spokes to the inner wall of the rim.

[0046] The specific structure of the welding mechanism 24 is as follows:

[0047] The welding mechanism 24 includes a welding table 241. To facilitate the positioning of the rim, a clamp 244 for limiting and releasing the rim is fixedly connected to the top of the welding table 241. The clamp 244 has an annular cross-sectional shape, and the rim is limited to the outside of the clamp after being released. The robotic arm grabs the rim and releases it onto the clamp 244 until the rim is fitted and limited on the clamp 244.

[0048] The welding platform 241 is provided with a welding frame. Specifically, the welding frame comprises an upper frame base 242, the bottom of the upper frame base 242 is fixedly connected with a plurality of frame rods 2421 (for support), and the frame rods 2421 penetrate through the welding platform 241.

[0049] The welding frame is provided with a welding assembly 243, the welding assembly 243 comprises a lifting cylinder 2433, and the cylinder barrel of the lifting cylinder 2433 is fixedly installed at the top center of the upper frame base 242. Meanwhile, the lifting cylinder 2433 is provided with a lifting rod 24332, and the bottom of the lifting rod 24332 is provided with a welding gun structure 2434.

[0050] Specifically, the piston rod of the lifting cylinder 2433 is fixedly connected with a lifting seat 24331 (the piston rod of the lifting cylinder 2433 is slidingly connected with the upper frame base 242), and the lifting rod 24332 is fixedly installed at the bottom of the lifting seat 24331.

[0051] Meanwhile, the top of the lifting seat 24331 is fixedly connected with a plurality of slide guide rods which are slidingly connected with the upper frame base 242. The slide guide rods are used to improve the stability during lifting.

[0052] Meanwhile, the welding gun structure 2434 comprises a welding gun mounting seat 24344 which is fixedly installed at the bottom of the lifting rod 24332, and a plurality of welding gun parts are fixedly connected with the welding gun mounting seat 24344.

[0053] During welding, each welding gun part corresponds to the connection part between a spoke arm and a rim on a spoke to realize synchronous welding.

[0054] Specifically, the welding gun part comprises a welding gun fixing seat 24343 which is fixedly connected with the welding gun mounting seat 24344 (a adjusting short rod 243432 is slidingly connected with the welding gun fixing seat 24343, the adjusting short rod 243432 is fixedly connected with the welding gun mounting seat 24344, in this way, the positions of all welding gun heads 24342 can be adjusted during actual work, the adjusting mode is sliding adjustment, and in order to adjust the position, a bolt for extruding and positioning the welding gun head is threadedly connected with the welding gun fixing seat 24343 according to the existing mode), a welding gun clamping seat 243431 is fixedly connected with the side wall of the welding gun fixing seat 24343, and a welding gun head 24342 is fixedly connected in the welding gun clamping seat 243431.

[0055] The welding gun head 24342 is a welding head used in conventional welding equipment disclosed in the prior art, and the top of the welding head is electrically connected through connected wires, which is the same as the existing welding head.

[0056] During the operation, after the spokes and rims are loaded, the entire welding gun structure 2434 is lowered under the drive of the lifting cylinder 2433, and the connection between the spoke arm and the rim is welded synchronously through each welding gun head 24342.

[0057] Because the above method is used to achieve synchronous welding, not only is the welding efficiency greatly improved, but the synchronous welding process also ensures that the connection strength between each spoke arm and the rim is the same after welding, which greatly improves the welding quality and effectively increases the welding quality of the wheel hub.

[0058] Example 2

[0059] like Figures 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, during the welding process, a large number of welding sparks fly upwards, which can easily cause the wires connected to the welding torch head 24342 to catch fire and damage the equipment. Therefore, a welding spark block 24341 is fixedly connected to the bottom of the welding torch mounting base 24344, and the welding torch head 24342 is confined within the welding spark block 24341. During the welding process, the flying sparks are blocked by the welding spark block 24341 and fly downwards to the ground.

[0060] Similarly, to protect the welding torch tip 24342, the aforementioned welding spark block 24341 is provided with several limiting port structures 243411 for limiting the welding torch tip 24342.

The welding torch tip 24342 is protected by the limiting port structures 243411, which have a certain depth.

[0061] The bottom of the welding head 24342 is the welding end, which penetrates through the bottom of the elliptical through hole 2434111.

[0062] Example 3

[0063] like Figures 1-5 As shown, in this embodiment, based on the structure of Embodiment 2, a slag removal mechanism is fixedly connected to the aforementioned frame rod 2421. The slag removal mechanism removes slag during the welding process and simultaneously cools the welding area.

[0064] Specifically, the slag removal mechanism includes a plurality of slag removal pipes 245, each slag removal pipe 245 including a straight pipe section, the straight pipe section being integrally formed with a bent pipe section, the bent pipe section facing the welding table 241.

[0065] According to the existing welding blowing cooling mode, the above-mentioned welding slag blowing pipe 245 is communicated on the external pumping pipe. The external pumping pipe is communicated to the gas source, so that the cooling gas flow such as nitrogen is blown to the workpiece during welding, and the welding slag is removed and the temperature is reduced.

[0066] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
