Description

TECHNICAL FIELD

[0001] The utility model belongs to the rim polishing technical field especially, relate to a rim polishing slag removal transmission device. BACKGROUND

[0002] The rim is the supporting mechanism on the hub, and is the core structure of the hub as the load bearing structure between the tire and the spoke. In the production and processing process, the aluminum alloy material for producing the rim needs to be welded after being formed by winding. The welding forms a closed cylindrical structure, and the welding slag on the inner and outer sidewalls of the rim blank needs to be removed.

[0003] The inner and outer sidewalls of the rim are kept smooth after the welding slag is removed. In the production and processing process, the welding slag removal method of the rim is affected by the limitation of the cylindrical structure. The welding slag on both sides can only be removed separately during the removal process (specifically, the rim is locked on the tooling, and a handheld polishing device is used for polishing. The welding seam on the inner sidewall of the rim is difficult to polish conveniently due to the secret position and the influence of the structure shape of the rim). Therefore, this method leads to low welding slag removal efficiency and cannot match the high-speed production line.

[0004] At the same time, after the welding slag of the rim is removed in the production and processing process, the rim needs to enter the subsequent processing procedure, such as the detection procedure (detection of welding). The current production method is that the rim is manually fed to the feeding end of the belt conveyor after polishing is completed, and then the rim is placed on the detection table of the detection procedure equipment at the discharging end.

[0005] In addition, the low polishing efficiency of the rim seriously affects the overall hub production efficiency due to the low efficiency of the initial stage of the rim production and processing.

[0006] Therefore, a production equipment with high-efficiency polishing, high-efficiency feeding, and high-efficiency grabbing and detection can not only improve the production efficiency, but also greatly reduce the manual labor in the production process, which is very important for providing production capacity benefits.

[0046] Example 1

[0047] like Figures 1-7 As shown, a wheel rim grinding and slag removal conveying device includes a conveying mechanism 12, a grinding and slag removal mechanism 11 disposed at the feed end of the conveying mechanism 12, and a robotic arm mechanism 13 disposed at the discharge end of the conveying mechanism 12.

[0048] During operation, the slag removal mechanism 11 quickly removes the slag from the weld seams on the inner and outer walls of the wheel rim, then rapidly pushes it to the conveying mechanism 12 for transport to the discharge end. The robotic arm mechanism 13 then quickly grabs the material and loads it onto the worktable of subsequent equipment, such as the testing equipment. This integrated grinding, conveying, and unloading process significantly increases production efficiency.

[0049] The specific structure of the grinding and slag removal mechanism 11 is as follows:

[0050] The grinding and slag removal mechanism 11 includes a worktable 111, on which a pushing component for pushing the wheel rim onto the transmission mechanism 12 is mounted and connected.

[0051] Specifically, the pushing assembly includes a pushing cylinder 112 installed at the top of the workbench 111 (the cylinder barrel of the pushing cylinder 112 is fixedly installed at the top of the workbench 111 via a cylinder barrel base), a pushing seat mounting base 1121 is fixedly connected to the piston rod of the pushing cylinder 112, and a pushing platform 113 with a pushing wheel rim is fixedly assembled and connected to the pushing seat mounting base 1121 (the two are fastened by bolts).

[0052] Meanwhile, the push platform 113 is provided with an arc-shaped limiting groove that matches the shape of the wheel rim A. During the process of pushing the wheel rim A, the wheel rim A is limited and engaged in the arc-shaped limiting groove, which increases the stability of the push.

[0053] The aforementioned slag removal and grinding mechanism 11 also includes a slag removal and grinding assembly. Specifically, the slag removal and grinding assembly simultaneously removes slag from the weld seams on the inner and outer walls of the rim A.

[0054] Specifically, the grinding slag removal assembly includes a grinding cylinder 116 installed at the bottom of the workbench 111 (the cylinder barrel of the grinding cylinder 116 is fixedly installed at the bottom of the workbench 111 through a cylinder barrel mounting seat, which is the same as the existing mode), and a grinding rod 115 is connected to the grinding cylinder 116.

[0055] Specifically, the piston rod of the grinding cylinder 116 is fixedly connected with a grinding rod mounting seat 1161, and the grinding rods 115 are fixedly installed on the top of the two sides of the grinding rod mounting seat 1161. The distance between the grinding rods 115 corresponds to the thickness of the rim A.

[0056] Correspondingly, a sliding port is formed on the workbench 111 and matched with the grinding rods 115, and the grinding rods 115 are slidingly connected with the sliding port.

[0057] During the working process, under the driving of the grinding cylinder 116, at this time, the grinding rods 115 are quickly lowered due to the contact on the weld, and the grinding rods 115 along the upper end to the lower end of the weld quickly remove the slag on the weld.

[0058] This mode realizes synchronous grinding of the welds on the inner and outer sidewalls of the rim A, and effectively solves the technical defect that the weld on the inner side of the rim A is not easy to grind due to the secret position. The synchronous grinding on both sides greatly improves the grinding efficiency.

[0059] The above grinding rod 115 is a conventional grinding rod capable of grinding metal materials disclosed in the prior art, which has a rough structure for rubbing the slag on the grinding rod 115.

[0060] In order to realize the working process, keep the rim A from loosening during the grinding process, and ensure that the grinding rods 115 grind neatly along the weld, the above grinding slag removal assembly further includes a plurality of rod structures for abutting against the outer sidewall of the rim A. Specifically, the rod structure includes a pair of rods for abutting against the positions on both sides of the outer sidewall of the rim A.

[0061] The abutting of the rods on both sides realizes the keeping of the rim A during the grinding process, which greatly improves the accuracy of the grinding.

[0062] Embodiment 2

[0063] As shown in the drawings, Figures 1-7 On the basis of the structure of embodiment 1, the above transmission mechanism 12 includes a belt machine, wherein the belt machine is a conventional transmission belt machine disclosed in the prior art, and the main structure thereof is the same as that of the existing belt machine, including a rack 121, and a belt cylinder is installed at both ends of the rack 121. The transmission belt 122 (the same as the existing belt machine, the motor installed on the belt cylinder drives the rotation of the belt cylinder, and then the belt transmits the material) is installed between the belt cylinders.

[0064] In order to keep the wheel rim A in a supporting transmission mode during the work process, facilitate the posture correction of the wheel rim A during the transmission process, the transmission belt 122 is integrally formed with elastic ribs 1221 arranged at both sides (the bottom of the wheel rim A straddles the elastic ribs 1221) during the transmission process of the transmission belt 122, and the wheel rim A is supported between the tops of the elastic ribs 1221. The elastic ribs 1221 are made of elastic material and thus move synchronously with the belt.

[0065] Since the wheel rim A is supported on the elastic ribs 1221, the supporting surface is small, and thus it is easier to move during the posture correction.

[0066] Specifically, the front and rear sides of the rack 121 are respectively fixedly provided with a plurality of guide rod structures for guiding the wheel rim A (the guide rod structures are symmetrically distributed in the front-rear direction), and the transmission posture of the wheel rim A is corrected through the guide rod structures.

[0067] Specifically, when the posture of the wheel rim A approaches the front side, the moving wheel rim A abuts against the guide rod structure 124 on the front side, and the posture of the wheel rim A is corrected under the pushing of the guide rod structure 124. In this way, the posture correction of the wheel rim A is facilitated, and the precise grabbing of the subsequent mechanical arm is prepared.

[0068] Specifically, the guide rod structure 124 includes a pair of guide rod frames 1241 fixedly installed on the rack 121 (the bottom of the guide rod frame 1241 is fixedly connected with a base table, and the base table is fixedly connected with the rack 121), and a pair of horizontally arranged guide rods 1242 are respectively installed between the guide rod frames 1241. Specifically, the two ends of the horizontal guide rod 1242 are respectively fixedly connected with guide rod seats, the guide rod seats are respectively fixedly connected with longitudinal connecting rods, and the guide rod seats are fixedly connected with the longitudinal connecting rods on the guide rod frame 1241.

[0069] During the work process, the deviated wheel rim A abuts against the horizontal guide rod 1242, and under the abutting and pushing of the horizontal guide rod 1242, the wheel rim A moves on the elastic ribs 1221 and abuts against the horizontal guide rod 1242 on the other side, and then the posture of the wheel rim A is corrected under the guidance of the horizontal guide rods 1242 on both sides. In this way, the technical defect that the posture of the wheel rim A is easily corrected in time after the posture of the wheel rim A is changed during the feeding and transmission process is effectively solved.

[0070] The discharge end of the rack 121 is fixedly connected with a baffle 123 for blocking the wheel rim A, which is used to prevent the wheel rim A from falling off the transmission belt 122.

[0071] Embodiment 3

[0072] As Figures 1-7As shown, the embodiment is based on the structure of embodiment 2, in order to realize automatic grabbing of the discharge end position rim A, further improve the production efficiency of the rim A, the above-mentioned mechanical arm mechanism 13 includes a mechanical arm 131 (wherein the mechanical arm 131 is a conventional industrial production mechanical arm 131 disclosed in the prior art).

[0073] In order to match the rim A grabbing, the above-mentioned mechanical arm 131 is provided with a grabbing tool 132 for grabbing the rim A; the grabbing tool 132 corresponds to the shape of the rim A.

[0074] Specifically, the grabbing tool includes a tool mounting bracket 1321 mounted on the mechanical arm 131, and a grabbing cylinder 1322 mounted on the tool mounting bracket 1321; the piston rod of the grabbing cylinder 1322 is fixedly connected with a grabbing plate 1323 (specifically, the piston rod of the grabbing cylinder 1322 is fixedly connected with a grabbing plate mounting seat 13221, and the grabbing plate 1323 is mounted on the grabbing plate mounting seat 13221); the tool mounting bracket 1321 and the grabbing plate 1323 are respectively fixedly connected with grabbing pressure seats 1324 on the side walls facing each other.

[0075] Through the grabbing tool, one side of the rim A can be grabbed during the grabbing process, and the other side of the rim A is the position of the weld, therefore, after grabbing one side, the mechanical arm 131 loads the rim A onto the detection table of the detection equipment, and this grabbing method can ensure that the weld is fully directed to the detection equipment such as a camera on the detection table.

[0076] Specifically, during the grabbing process, the mechanical arm 131 drives the tool mounting bracket 1321 to descend to the rim A, which is clamped into the gap between the grabbing plate 1323 and the end of the tool mounting bracket 1321, at this time, the grabbing cylinder 1322 works, drives the grabbing plate 1323 to close to the tool mounting bracket 1321, and then the grabbing pressure seats 1324 on both sides are pressed on the rim A, realizing full and stable grabbing of the rim A.

[0077] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples, and the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the present application should also belong to the protection scope of the present application.
