Description

Technical Field

[0001] The utility model relates to the technical field of wheel welding, in particular to a protective component for double-wire welding of a tubeless wheel assembly. Background Art

[0002] The wheel assembly is a circular rotating component installed on the vehicle axle. It is usually composed of structures such as the rim and spokes. Together with the tire, it supports the vehicle, transmits driving and braking forces, absorbs road impacts, and ensures smooth and safe driving of the vehicle. The wheel assembly is usually processed by welding, and the wheel spokes and rim are welded together by double wire welding to complete the assembly.

[0003] During the welding process of the wheel assembly, welding slag and other spatters are easily generated. These spatters have a high temperature. If they fall on the spokes and rims, they are likely to form spots, bumps and other defects, which will increase the difficulty of subsequent processing and cleaning, and may even require additional grinding, polishing and other processes to remove them, increasing production costs. Utility Model Content

[0004] The purpose of the utility model is to provide a protective component for double-wire welding of a tubeless wheel assembly, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0006] A protective assembly for twin-wire welding of a tubeless wheel assembly comprises a U-shaped frame, the upper surface of which is mounted an electric push rod. A lifting plate is mounted at the telescopic end of the electric push rod. A first telescopic rod is mounted on either side of the lower surface of the lifting plate. A fixing ring is mounted at both ends of the two first telescopic rods, and a rim cover is rotatably mounted on the inner wall of the fixing ring. A second telescopic rod is mounted in the middle of the lower surface of the lifting plate, and a spoke cover is rotatably mounted at the end of the second telescopic rod. A twin-wire welding gun is mounted on the lower surface of the lifting plate, with the gun tip of the twin-wire welding gun aligned with the gap between the rim cover and the spoke cover.

[0007] It can be seen that the lifting plate is driven down by the electric push rod, so that the rim cover can be covered on the rim, and the spoke cover is covered on the spoke. The welding point between the rim and the spoke corresponds to the gap between the rim cover and the spoke cover. Therefore, the connection between the two can be welded by a double-wire welding gun, and the welding slag and other spatters generated by the welding fall on the rim cover and the spoke cover, thereby avoiding the formation of spots, bumps and other defects on the spokes and rims due to falling spatters, reducing the subsequent processing and cleaning steps, and thus reducing production costs.

[0008] Furthermore, a fan is installed on the upper surface of the lifting plate, the suction end of the fan is connected to a suction pipe, the outer surface of the double-wire welding gun is provided with a suction ring, and the end of the suction pipe is connected to the suction ring, and an activated carbon filter is installed at the output end of the fan.

[0009] Furthermore, a first spring is sleeved on the outer surface of the first telescopic rod, and the two ends of the first spring are respectively in contact with the lifting plate and the fixing ring; a shoulder is provided on the outer surface of the second telescopic rod, and a second spring is sleeved on the outer surface of the second telescopic rod, and the two ends of the second spring are respectively in contact with the lifting plate and the shoulder.

[0010] Furthermore, two grooves are provided on the upper surface of the spoke cover, a collecting tray is provided inside the groove, and a handle is installed on the upper surface of the collecting tray.

[0011] Furthermore, the lower surfaces of the rim cover and the spoke cover are both provided with rubber pads, and the outer surfaces of the rubber pads are provided with anti-slip grooves.

[0012] Furthermore, the inner walls on both sides of the U-shaped frame are provided with limiting sliding grooves, the interior of the limiting sliding grooves is provided with limiting sliders, and the ends of the limiting sliders are connected to the lifting plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0014] 1. The utility model drives the lifting plate to descend through an electric push rod, so that the rim cover plate can cover the rim, and the spoke cover plate covers the spokes. The welding point between the rim and the spoke corresponds to the gap between the rim cover plate and the spoke cover plate. Therefore, the connection between the two can be welded by a double-wire welding gun, and the welding slag and other spatters generated by the welding fall on the rim cover plate and the spoke cover plate, thereby avoiding the formation of spots, protrusions and other defects on the spokes and rim due to falling spatters, reducing the steps of subsequent processing and cleaning, and thus reducing production costs.

[0015] 2. The utility model uses the suction force generated by the fan to act on the bottom of the suction ring, so the smoke generated during the welding process can be directly inhaled and discharged after purification and filtration through the activated carbon filter, thereby ensuring the working environment on site and protecting the health of the workers.

Therefore, the terms "first" and "second" may explicitly or implicitly include one or more of the features.

[0024] See also Figure 1-Figure 4The present invention provides a protective assembly for double-wire welding of a tubeless wheel assembly, comprising a U-shaped frame 100. An electric push rod 101 is mounted on the upper surface of the U-shaped frame 100. A lifting plate 102 is mounted at the telescopic end of the electric push rod 101. A first telescopic rod 103 is mounted on both sides of the lower surface of the lifting plate 102. A fixing ring 104 is mounted at the ends of the two first telescopic rods 103. A rim cover 105 is rotatably mounted on the inner wall of the fixing ring 104. A second telescopic rod 106 is mounted in the middle of the lower surface of the lifting plate 102. A spoke cover 107 is rotatably mounted at the end of the second telescopic rod 106. A double-wire welding gun 108 is mounted on the lower surface of the lifting plate 102. The welding gun head of the double-wire welding gun 108 is aligned with the gap between the rim cover 105 and the spoke cover 107.

[0025] When in use, the rim and the spoke are first placed on a rotating table (not shown in the figure). The rotating table can drive the rim and the spoke to rotate and fix them by a clamp (not shown in the figure). Then, the electric push rod 101 is started. The electric push rod 101 drives the lifting plate 102 to descend, and the rim cover plate 105 is covered on the rim, and the spoke cover plate 107 is covered on the spoke. At this time, the welding gun head of the double-wire welding gun 108 passes through the gap between the rim cover plate 105 and the spoke cover plate 107 and is aligned with the welding point of the rim and the spoke. Then, the rotating table is started to drive the rim and the spoke to rotate. During the rotation, the connection between the two can be welded by the double-wire welding gun 108, and the spatter such as welding slag generated by the welding falls on the rim cover plate 105 and the spoke cover plate 107, thereby avoiding the formation of spots, protrusions and other defects on the spoke and rim due to falling spatter, reducing the steps of subsequent processing and cleaning, and thus reducing production costs.

[0026] Specifically, a fan 200 is installed on the upper surface of the lifting plate 102, and the suction end of the fan 200 is connected to the suction pipe 201. The outer surface of the double-wire welding gun 108 is provided with a suction ring 202, and the end of the suction pipe 201 is connected to the suction ring 202. An activated carbon filter 203 is installed at the output end of the fan 200. During the welding process, the fan 200 can be started, and the suction force generated by the fan 200 acts on the bottom of the suction ring 202. Therefore, the smoke generated during the welding process can be directly inhaled and discharged after purification and filtration by the activated carbon filter 203, thereby ensuring the working environment on site and protecting the health of the staff.

[0027] Specifically, the outer surface of the first telescopic rod 103 is provided with a first spring 300, and the two ends of the first spring 300 are respectively in contact with the lifting plate 102 and the fixing ring 104, and the outer surface of the second telescopic rod 106 is provided with a shoulder 301, and the outer surface of the second telescopic rod 106 is provided with a second spring 302, and the two ends of the second spring 302 are respectively in contact with the lifting plate 102 and the shoulder 301. Through the arrangement of the first spring 300, the rim cover 105 can be pressed against the rim, increasing the friction between the two, so that the rotating table can drive the rim cover 105 to rotate synchronously during the rotation process. Through the arrangement of the shoulder 301 and the second spring 302, the friction between the spoke cover 107 and the spokes can be increased, so that the rotating table can drive the spoke cover 107 to rotate synchronously. Therefore, it can be avoided that during the rotation of the rotating table, the rim cover 105 and the spoke cover 107 rotate asynchronously with the rim and the spokes, resulting in friction, thereby affecting the appearance.

[0028] Specifically, two grooves 400 are provided on the upper surface of the spoke cover 107, and a collection tray 401 is provided inside the groove 400. A handle 402 is installed on the upper surface of the collection tray 401. After the welding slag generated during the welding process falls into the collection tray 401, it can be taken out through the handle 402, which makes it easier to clean the welding and improves the portability of use.

[0029] Specifically, the lower surfaces of the rim cover plate 105 and the spoke cover plate 107 are both provided with rubber pads, and the outer surfaces of the rubber pads are provided with anti-slip grooves. The setting of the rubber pads and the anti-slip grooves can prevent the rim cover plate 105 and the spoke cover plate 107 from causing damage to the rim and the spokes, play a buffering and protective role, and further increase the friction between the two to avoid the occurrence of asynchronous rotation.

[0030] Specifically, limiting grooves are provided on the inner walls on both sides of the U-shaped frame 100, and limiting sliders are arranged inside the limiting grooves, and the ends of the limiting sliders are connected to the lifting plate 102. By setting the limiting grooves and the limiting sliders, the stability of the lifting plate 102 during lifting can be improved, and the welding quality can be improved.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
