The present invention relates to the technical field of wheel grinding, and specifically, to a device for cleaning burrs after wheel machining.
After wheel machining, burrs on the front side are mainly at the rim and the cap section. In the presence of an annular circle of burrs, much difficulty is brought to removal, and the existing burr removing process hardly guarantees the roundness and concentricity of the cap section and the rim. Besides, the removing efficiency is low, the effect is poor, and the burrs are unlikely to clean thoroughly, so a device for automatically removing wheel front burrs is urgently needed in production.
The present invention is aimed at providing a device for automatically cleaning burrs at the rim and the cap section of the front side of a wheel, wherein the device can be used for automatic production, thereby improving the production efficiency and improving the burr removing effect.
In order to fulfill the above aim, the present invention adopts the technical solution: a wheel front burr cleaning device is composed of a rack, a lifting cylinder, a support frame, guide posts, guide sleeves, a lifting table, a brush, bearing seats, bearings, a turnover platform, a servo motor I, a coupling, guide rails, a left sliding plate, a right sliding plate, a gear rack structure, a servo motor II, clamping wheels, a clamping cylinder, a feeding roller bed, a working roller bed, a discharge roller bed, a cutter system support frame, a rim burr cutter adjusting cylinder, a rim burr cutter feeding cylinder, a left sliding table, a rim burr cutter, a cap section burr cutter feeding cylinder, a right sliding table, adjusting guide rails, a cap section burr cutter and a cap section burr cutter adjusting cylinder.

The lifting cylinder controls ascending and descending of the lifting table to realize upward feeding and downward reset of the brush.
The servo motor I is fixed on the side of the rack, the output end of the motor is connected with the turnover platform via the coupling, the middle part of the turnover platform is a cuboid, circular shafts are arranged on the left side and right side of the turnover platform, and the shafts are matched with the bearings.

The servo motor II is installed on the left sliding plate, the clamping wheels are installed on the shaft connected with the output end of the motor, two clamping wheels are installed on each of the left sliding plate and the right sliding plate, and the clamping cylinder is connected with the left sliding plate. When the clamping cylinder drives the left sliding plate to move, the right sliding plate moves synchronously with the left sliding plate under the action of the gear rack structure, and the four clamping wheels can clamp a wheel. When the servo motor II drives the clamping wheels to rotate, low-speed rotation of the wheel in the clamped state can be realized. The structures above and below the turnover platform are completely consistent, and wheel positioning clamping rotating systems are distributed symmetrically. The servo motor I controls the turnover platform to rotate 180 degrees every time, thereby realizing cyclic switching of the positioning clamping systems above and below the turnover platform.
The cutter system support frame is installed at the edges of the feeding roller bed rack and the discharge roller bed rack. The two adjusting guide rails are symmetrically installed at the top of the cutter system support frame, and the left sliding table and the right sliding table are respectively installed on the adjusting guide rails.
The rim burr cutter feeding cylinder is installed on the left sliding table, the rim burr cutter is installed at the output end of the cylinder, and the rim burr cutter is used for removing burrs at the rim of the wheel. The rim burr cutter adjusting cylinder is installed on the left upper part of the cutter system support frame, the output end of the cylinder is connected with the left sliding table, and the position of the rim burr cutter can be adjusted by left and right sliding of the left sliding table, so that the rim burr cutter is suitable for removing burrs on wheels having different outer diameters.
The cap section burr cutter feeding cylinder is installed on the right sliding table, the cap section burr cutter is installed at the output end of the cylinder, and the cap section burr cutter is used for removing burrs at the cap section of the wheel. The cap section burr cutter adjusting cylinder is installed on the right upper part of the cutter system support frame, the output end of the cylinder is connected with the right sliding table, and the position of the cap section burr cutter can be adjusted by left and right sliding of the right sliding table, so that the cap section burr cutter is suitable for removing burrs on wheels having different cap section diameters.

After the burrs are removed from the wheel above the turnover platform and the burrs are brushed from the wheel below the turnover platform, the servo motor I is started to drive the turnover platform to rotate 180 degrees, at the moment, the wheel from which the burrs are brushed is switched to the upper part, the clamping wheels loosen the wheel, the working roller bed rotates to feed the wheel into the discharge roller bed, then next wheel is prepared to be positioned and clamped, the wheel from which the burrs are removed is switched to the lower part, and burrs are prepared to be brushed. Burrs are removed and then brushed for all wheels, and so on.
When the outer diameter of the wheel or the diameter of the cap section is changed, correspondingly adjusting the positions of the burr cutters is enough.
