Description

TECHNICAL FIELD

[0001] The utility model belongs to hub processing technical field, especially related to a rim and spoke welding production line. BACKGROUND

[0002] The core components of the hub include the rim and the spokes welded on the inner side of the rim, and the tire is subsequently installed on the rim of the hub.

[0003] In the production and processing process, after the rim welding process is completed, the rim and the spoke need to be welded into an integrated structure. During the welding process, the rim and the spoke need to be fed to the welding equipment respectively. However, since the rim and the spoke belong to different production lines, the current welding method is to feed the rim unloaded from the rim production line to the welding equipment, and then unload the spoke from the spoke production line and feed it to the welding production line.

[0004] The current way of unloading the spoke and the rim from the production line is very different in shape, so it can only be unloaded by manual feeding, and the spoke is unloaded after the rim is unloaded. Since the two belong to different production lines, the manual feeding and unloading method cannot be synchronized with the production speed of the equipment in the actual processing process. The manual operation method cannot be adjusted according to the production line product.

[0005] At the same time, the manual feeding method cannot be synchronized with the production line speed, which seriously affects the production process from the production line. During the process of manually feeding the rim and the spoke to the welding equipment, the spoke needs to be placed in the rim. Although the welding table of the welding equipment is equipped with a clamp, in the actual working process, there is still a mismatch between the rim and the spoke due to human error (such as the spoke not being completely clamped into the clamp), and the hub product formed after welding can only be treated as waste.

[0006] Therefore, it is obvious that the efficiency of the current manual operation method in the workshop is too low, and the waste rate of the processed products is high. INVENTION CONTENTS

[0045] As Figs. 1-6As shown, a kind of rim, spoke welding production line, including the rim mechanical arm 23 for grabbing rim and the spoke conveying mechanism for transmitting spoke B, and the spoke mechanical arm 23 for grabbing spoke in the position of spoke conveying mechanism discharge end location.Rim, spoke welding production line also includes welding mechanism 24 (specifically same as the welding device of prior art welding rim, spoke B, welding mechanism 24 includes welding table, and welding machine is installed on the welding table, same as the welding device of prior art welding rim, spoke B, welding table is installed with the clamp of spoke B feeding rim, spoke B)

[0046] During operation, first, the rim mechanical arm 23 is first grabbed and placed on the welding table, then the spoke conveying mechanism is transmitted to the discharge end position, then the spoke mechanical arm 23 is grabbed and fed to the welding table and put into the rim, then the welding equipment on the welding mechanism 24 is welded.

[0047] In order to realize the rim grabbing, the above-mentioned rim mechanical arm 23 includes a rim mechanical arm body 231 (the rim mechanical arm body 231 is a conventional mechanical arm for prior art industrial production), and a rim grabbing structure 232 for grabbing the rim is installed on the rim mechanical arm body 231. The rim grabbing structure 232 is used to grab the cylindrical structure of the rim, and the grabbed rim is kept flat on the clamp on the welding table.

[0048] Specifically, the rim grabbing structure 232 includes a grabbing support 2321 (in the shape of a frame structure, the left end of which is a mounting portion 23211 mounted on the rim mechanical arm body 231) mounted on the rim mechanical arm body 231, a cylinder 2326 is mounted on the grabbing support 2321, and a first grabbing arm 2323 is fixedly connected to the piston rod of the cylinder 2326; the grabbing support 2321 is fixedly connected with a second grabbing arm 2322 cooperating with the first grabbing arm 2323.

[0049] The first grabbing arm 2323 and the second grabbing arm 2322 are the same shape, specifically, the first grabbing arm 2323 and the second grabbing arm 2322 are integrally formed with a grabbing arm rod 2324 (the grabbing arm rod 2324 has sufficient extension length to stably grab the cylindrical structure of the rim) grabbed on the rim. In order to better clamp the rim, an arc-shaped notch is formed on the inner side wall of the grabbing arm rod 2324.

[0050] Meanwhile, in order to increase the stability of the movement of the first grabbing arm 2323, two spaced apart slide rods 2325 are fixedly connected between the first grabbing arm 2323 and the second grabbing arm 2322, and the slide rods 2325 are slidingly connected to the grabbing support 2321; the front end of the slide rod 2325 is fixedly connected with a blocking end seat 23251 blocking the first grabbing arm 2323 (to avoid the first grabbing arm 2323 from coming off).

[0051] During the operation, firstly, driven by the rim robotic arm body 231, the first gripping arm 2323 on the rim gripping structure 232 extends towards the second gripping arm 2322 to the outside of the rim. Then, driven by the cylinder 2326, the first gripping arm 2323 approaches the second gripping arm 2322 until the first gripping arm 2323 cooperates with the second gripping arm 2322 to clamp the rim between the gripping arm rods 2324. Subsequently, the rim robotic arm body 231 sends the gripped rim onto the worktable of the welding equipment.

[0052] The above method enables the handling of wheel rims that are difficult to grasp using a robotic arm, and allows the wheel rim robotic arm body 231 to cooperate with the wheel spoke robotic arm body 251. The wheel rim robotic arm body 231 and the wheel spoke robotic arm body 251 can then cooperate with the production line, greatly improving the smoothness of production and ensuring efficient material handling and welding operations.

[0060] In order to realize the cooperation of the spoke B at the discharging end with the spoke mechanical arm 23 to be grabbed, the discharging end of the above-mentioned conveyor is provided with a spoke upending structure 22 cooperating with the spoke mechanical arm 23.

[0061] That is, the spoke B is corrected in shape and upended by the spoke upending structure 22, specifically, the spoke upending structure 22 comprises an upending clamping plate 221 for clamping the spoke B.

[0062] At the same time, the upending clamping plate 221 is provided with a bayonet 222 (towards the feeding end of the belt), and after the spoke B is transmitted to the discharging end position on the transmission belt, the spoke B is clamped into the bayonet 222 (the shape of the bayonet 222 is V-shaped).

[0063] Specifically, when the spoke B encounters the V-shaped bayonet 222, at this time, under the guidance of the bayonet 222, the spoke B is clamped into the V-shaped bayonet 222, and in this process, because the spoke B is limited in the bayonet 222, at this time, the spoke B limited in the bayonet 222 is automatically corrected to be vertical state with the upending of the following upending cylinder, facilitating the mechanical arm to grab.

[0064] Specifically, the upending cylinder 223 is installed at the bottom of the upending clamping plate 221. Specifically, the upending cylinder 223 is installed at both sides of the bottom of the upending clamping plate 221, and the bottom of the upending cylinder 223 is provided with a cylinder bracket 2231, and the cylinder bracket 2231 is installed on the conveyor rack 261.

Then, the spoke B is corrected to be vertical after being lifted, and the mechanical arm can easily grab the spoke B in the correct position. In this way, the accuracy of the mechanical arm grabbing is greatly improved, and the spoke B can be placed into the rim in the correct posture.
