Description

Technical Field

[0001] The invention relates to the field of grinding and polishing, and in particular to a grinding and polishing system for automobile wheel hubs. Background Art

[0002] The car wheel hub is a cylindrical metal part that supports the tire with the axis as the center of the inner contour of the car tire. It is the foundation of the tire. The shape of the wheel hub determines the heat dissipation efficiency of the brake system, so it is critical to choose a wheel hub with a reasonable shape. While considering heat dissipation and aesthetics, you should also pay attention to the service life of the wheel hub. If there are too few supporting strips, the anti-twisting, anti-impact ability and strength will be poor, and the service life of the wheel hub will be shortened. In order to ensure the service life and aesthetics of the car wheel hub at the same time, repairing and polishing the wheel hub is an essential step.

[0003] After the die-cast blank of the wheel hub is turned by the machine tool, it will produce many irregular burrs and flashes, with many arc shapes. The burrs at the wheel hub window are the most obvious. It is difficult to polish manually, and it is necessary to change the tool for polishing many times. The labor intensity is high, the efficiency is low, the dust is large, and the polishing is uneven and the consistency is poor. The on-site work is labor-intensive, the environmental noise is high, and the dust is generated, which directly affects the health of the operators. In addition, when workers polish some parts of the wheel hub (the inside of the wheel hub, grooves, gaps, etc.), the small working space greatly affects the polishing efficiency and polishing effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a vehicle wheel hub grinding and polishing system in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an automobile wheel hub grinding and polishing system, characterized in that it includes: a material table for placing the wheel hub, a polishing machine for polishing the wheel hub, a sanding machine for polishing the wheel hub, a belt winding polishing device for polishing the inner side of the wheel hub, an inner seam polishing device for polishing the groove of the wheel hub, an insertion polishing device for polishing the fine groove of the wheel hub, and an automatic clamping device for clamping the wheel hub and cooperating with the polishing machine, the sanding machine, the belt winding polishing device, the inner seam polishing device, and the insertion polishing device, the automatic clamping device includes an industrial robot and a clamping tool detachably connected to the industrial robot, the clamping tool includes a connector connected to the end of the industrial robot, a clamping seat fixed on the connector, two clamping plates arranged opposite to each other on the clamping seat, and a clamping device for driving The driving clamping assembly of the clamping plate moving on the clamping seat, the clamping plate is provided with a plurality of clamping wheels that abut against the wheel hub, and a clamping space for fixing the wheel hub is formed between the clamping wheels. The driving clamping assembly includes a sliding connection structure arranged between the clamping seat and the clamping plate, and the clamping plate is provided with staggered racks on one end facing the clamping seat, and a gear that can rotate on the clamping seat is provided at one end of the clamping seat corresponding to the rack, and the gear is arranged between the two racks and meshes with the racks at both ends. The clamping seat is provided with at least one driving cylinder connected to the clamping plate, and the driving cylinder drives the clamping plate to move forward or reverse on the clamping seat, and then the wheel hub is clamped by the clamping tooling, and then the wheel hub is polished in cooperation with the polishing machine, the sanding machine, the belt winding polishing device, the inner seam polishing device, and the insertion polishing device through the industrial robot.

[0006] By adopting the above technical solution, the wheel hub includes a tire bead seat, an inner wheel rim and an outer wheel rim protruding at both ends of the tire bead seat, and the inner side, grooves, and gaps of the outer surface of the wheel hub. When the wheel hub is polished and polished, it is only necessary to place the wheel hub on the material table, and the industrial robot will automatically work through the clamping tooling, wherein one end of the clamping seat of the clamping tooling is connected to the industrial robot through a connector, and the other end drives the clamping plate to move by driving the clamping assembly, so that the clamping wheel fixes and clamps the inner wheel rim of the wheel hub, wherein the clamping plate is moved on the clamping seat through a sliding connection structure without falling, and the clamping plate is connected to the inner wheel rim of the wheel hub by the sliding connection structure. A gear is arranged in the clamping seat, and a staggered rack is arranged on each clamping plate. Both ends of the gear are meshed with the rack. When the driving cylinder drives one clamping plate to move, the rack drives the other clamping plate to move in the opposite direction through the gear, so that the clamping plate moves forward or backward on the clamping seat, thereby adjusting the size of the clamping space. That is, when the wheel hub needs to be fixed, it is only necessary to place the wheel hub in the clamping space, and then drive the driving cylinder to drive a clamping plate to move, so that the clamping space can be reduced and the wheel hub can be quickly and tightly fixed on the clamping fixture, wherein the clamping wheel forms a tapered portion with a gradually decreasing diameter toward one end of the mounting shaft. , because the wheel hub includes a bead seat and an inner rim and an outer rim protruding at both ends of the bead seat, the outer rim needs to face outward during grinding, so the clamping tool mainly clamps the inner rim part, and the structure of the inner rim part is a hump and an inner lip with an outer diameter gradually increasing from the bead seat to the inner rim. Therefore, by setting a tapered part with a gradually decreasing diameter at the clamping wheel, it can just clamp the inner rim part with an outer diameter gradually increasing, and the wheel hub is stably fixed on the clamping tool, thereby improving the stability during clamping and grinding, and then the clamped wheel hub is polished by a preset program on a polishing machine, a sanding machine, or a winding machine through an industrial robot.

Among them, an angle grinder or an output motor is arranged on the insertion grinding component, so that the angle grinder outputs through grinding. The wheel rotates, and the grinding head synchronous belt drives the extended transmission wheel equipped with the grinding head to rotate and grind. The setting of the offset plate increases the distance between the grinding head and the extended mounting frame, so that more positions of the wheel hub can be under the extended transmission wheel, so that the small grinding head can grind some narrow grooves of the wheel hub and process some places that traditional grinding belts and grinding wheels cannot grind.

The grinder mounting table drives the angle grinder to swing through the angle adjustment shaft, and drives the angle adjustment swing arm through the angle adjustment cylinder to realize the angle adjustment of the angle grinder, so that when grinding corresponding to different wheel hub parts, the position of the grinding head of the angle grinder can be adjusted so that the grinding head can be extended into different grooves for grinding. By arranging a flexible adjustment screw on the angle grinder mounting table, the flexible adjustment screw can control the swing range of the angle grinder through thread adjustment, and the flexible grinding space can be adjusted, thereby controlling the swing amplitude of the angle grinder during grinding, so as to adapt to the strength of different wheel hub grooves, and then reset through its own gravity to avoid excessive grinding, thereby further improving the grinding accuracy.
