TECHNICAL FIELD

The present application relates to the field of burr removal, specifically to a device for removing burrs at a wheel flange.

BACKGROUND ART

A flange weight reduction pit is often designed on the flange face of an aluminum alloy wheel in order to reduce the weight, flange drainage channels are designed on two sides of the flange weight reduction pit, the inner drainage channel communicates with the weight reduction pit and a central hole, and the outer drainage channel communicates with the weight reduction pit and the outer edge of the flange. The surface of the flange is machined and turned, and the flange weight reduction pit and the flange drainage channels are cast, so after machining, many burrs remain at the handover positions of casting and machining at the edges of the weight reduction pit and the drainage channels; these burrs need to be cleaned manually one by one, and there are a lot of irregular weight reduction pits and drainage channels, so the burrs are difficult to remove and easily missing to scrape, and the removal efficiency is low.

In order to fulfill the above aim, the present application adopts the following technical solution: a wheel flange burr brushing device comprises a frame, a lifting cylinder, lifting guide rails, a lifting platform, a support, a feeding cylinder, outer travel switches, a left feeding sliding plate, a left clamping cylinder, clamping guide rails, a left clamping sliding plate, burr brushes, clamping rollers, a right clamping sliding plate, clamping roller motors, a right clamping cylinder, inner travel switches, a right feeding sliding plate, an upper rack, a gear, a lower rack, a feeding guide rail, belt pulleys, driving belts, rotating shaft supports and servo motors.

The left clamping cylinder is connected with the left clamping sliding plate, the right clamping cylinder is connected with the right clamping sliding plate, the left clamping sliding plate and the right clamping sliding plate are respectively mounted on the clamping guide rails, a wheel can be positioned and clamped when the left clamping cylinder and the right clamping cylinder move synchronously, the four clamping roller motors are symmetrically mounted on the clamping sliding plates, the output ends of the clamping roller motors are connected with the clamping rollers to control rotation of the clamping rollers, and the wheel can be driven to rotate by the rotation of the clamping rollers, so that rotation of the wheel in the clamped state is realized.

The four lifting guide rails are symmetrically mounted on the lateral surfaces of the frame, the lifting cylinder is located in the center of the bottom of the frame, and the output end of the lifting cylinder is connected with the lifting platform to control ascending and descending of the lifting platform.

The feeding guide rail and the support are mounted on the lifting platform, the left feeding sliding plate and the right feeding sliding plate are mounted on the feeding guide rail and connected with each other via a gear rack structure, the feeding cylinder is mounted on the support, the output end of the feeding cylinder is connected with the left feeding sliding plate, and when the feeding cylinder drives the left feeding sliding plate to move left and right, the right feeding sliding plate moves synchronously with the left feeding sliding plate under the engagement effect of the gear and the racks. The outer travel switches and the inner travel switches are symmetrically mounted on the feeding guide rail; when the sliding plates touch the outer travel switches, the output end of the feeding cylinder extends; when the sliding plates touch the inner travel switches, the output end of the feeding cylinder retracts; thus, synchronous reciprocating motion of the left feeding sliding plate and the right feeding sliding plate within the fixed distance is realized.

The rotating shaft supports are symmetrically and fixedly mounted on the left feeding sliding plate and the right feeding sliding plate, the servo motors are mounted on the rotating shaft supports, the belt pulleys and the burr brushes are fixedly mounted on rotating shafts of the rotating shaft supports, the output ends of the servo motors are connected with the belt pulleys by the driving belts, and the servo motors can drive the burr brushes to rotate synchronously when driving the belt pulleys to rotate.

In an initial state, the output end of the feeding cylinder extends, the burr brush on the left feeding sliding plate rotates clockwise, and the burr brush on the right feeding sliding plate rotates anticlockwise, i.e., both of the burr brushes brush burrs from the outer side of a flange to a central hole; and when the sliding plates touch the inner travel switches, a signal is fed back to the servo motors, the servo motors reverse, the burr brush on the left feeding sliding plate rotates anticlockwise, and the burr brush on the right feeding sliding plate rotates clockwise, i.e., both of the burr brushes brush burrs from the central hole to the outer side of the flange. When the sliding plates touch the outer travel switches, a signal is fed back to the servo motors, the servo motors reverse, the initial state is restored, i.e., the burr brush on the left feeding sliding plate rotates clockwise, and the burr brush on the right feeding sliding plate rotates anticlockwise, both of the burr brushes brush burrs from the outer side of the flange to the central hole, the burr brushes reverse again till the sliding plates touch the inner travel switches, and recycling like this. Burrs are removed from the radial direction of the wheel flange by cyclic reversal of the burr brushes, and burrs on all weight reduction pits and drainage channels in the flange face of the wheel can be removed under the cooperation of rotation of the wheel. In this process, burrs at the wheel flange are thoroughly cleaned in all directions due to radial cyclic reversal torque and circumferential rotating force.

The working process of the wheel flange burr brushing device is as follows: after feeding, the left clamping cylinder and the right clamping cylinder move synchronously first to clamp the wheel; next, the clamping roller motors are started to drive the wheel to rotate; then the lifting cylinder is started to drive the lifting platform to ascend, meanwhile, the feeding cylinder is started to drive the left feeding sliding plate and the right feeding sliding plate to reciprocate, and the servo motors are started to drive the burr brushes to reverse cyclically; and the lifting cylinder stops moving when the burr brushes contact the flange face, the burr brushes begin brushing burrs, the lifting cylinder retracts after the burrs are brushed, the lifting platform descends and is reset, the clamping rollers loosen the wheel, the roller bed conveys the wheel to next procedure and receives next wheel having burrs to be removed, and recycling like this.

The present application may remove burrs from the edges of drainage channels and weight reduction pits of a wheel flange, effectively improve the burr removing effect and improve the burr removing efficiency; and the device is efficient, practical and flexible in operation, and may clean burrs at the flange in all directions and meet automatic continuous production.
