Description

Brake disc sorting gripper

Technical Field

The invention relates to the technical field of brake disc production equipment, in particular to a brake disc sorting gripper.

Background

The brake disc, simply a round disc, rotates as the vehicle travels. The brake calipers clamp the brake disc to generate braking force, and when the brake is stepped on, the brake calipers clamp the brake disc to play a role in decelerating or stopping. The brake disc has good braking effect and is easier to maintain than drum brake.

When the brake disc is produced, finished products are stacked in the storage bin, and the positions of the finished products are disordered. When the brake disc is processed, a single workpiece is required to be placed into a clamp of a machine tool according to the required gesture of the machine tool, so that the brake disc is required to be taken out of a material frame, however, because the position of the brake disc in a storage bin is not fixed, the brake disc is not easy to grasp by using a mechanical arm, and the grasping efficiency is low and unsafe.

The technical problems to be solved by the invention are as follows: in order to overcome the defects in the prior art, the invention provides a brake disc sorting gripper.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a brake disc letter sorting tongs, includes frame, electro-magnet and locates buffer assembly between frame and the electro-magnet, be equipped with a plurality of cameras that are used for shooing the brake disc in the frame, be equipped with proximity switch in the frame, buffer assembly includes spring, guide arm and response piece, electro-magnet, guide arm and response piece are upwards connected gradually from the bottom, the guide arm upper end passes the frame towards proximity switch direction extends, the spring housing is located on the guide arm, the spring both ends respectively with frame and electro-magnet are connected, the response piece is used for being close to under the drive of electro-magnet and guide arm proximity switch and with proximity switch cooperation.

The frame is used for bearing the electromagnet and the camera, the random stacking of brake disc is in the feed bin, the camera is used for shooting the position and the state of brake disc in the feed bin, so that the frame on the robot drives the electromagnet to move to the brake disc top to be sorted, the electromagnet is used for sucking out the brake discs in the feed bin one by one after being electrified, the spring is used for connecting the electromagnet on the frame, when the frame drives the electromagnet to descend just approaching the brake disc, because the contact area of the electromagnet and the brake disc is smaller, the electromagnet attracts little to the brake disc, the attraction is not firm, the position of the electromagnet needs to be continuously lowered, the contact area of the electromagnet and the brake disc is increased, in order to prevent the electromagnet and the brake disc from being rigidly collided to cause equipment damage, the contact area of the electromagnet and the brake disc is ensured to be sufficiently large, the equipment is prevented from being rigidly collided to cause damage, on the one hand, the guide rod is used for supporting the spring, the bending deformation is prevented, on the other hand, when the contact area of the electromagnet and the brake disc is sufficiently large, the electromagnet is driven by the frame, the electromagnet is driven by the electromagnet to descend to approach switch, the proximity switch, the electromagnet is used for attracting the electromagnet when the proximity switch is close to the contact area of the electromagnet, the electromagnet is normally attracted, and other objects are not normally attracted, and the attraction of the electromagnet is normally opened, and the attraction process is prevented.

Further, in order to prevent that the electro-magnet from being overweight from drawing the spring and warp, still include spacing subassembly, spacing subassembly includes fixed cover and even axle, even the axle is located the spring with between the electro-magnet, the sleeve cover is located even the axle outside with even axle sliding connection, sleeve upper end with frame fixed connection, be equipped with at least one waist circular through-hole along vertical direction setting on the sleeve lateral wall, even be equipped with on the axle with waist circular through-hole complex gag lever post. The limiting rod moves up and down in the kidney-shaped through hole and represents the movable range of the electromagnet in the vertical direction, when the limiting rod is arranged on the lower side of the kidney-shaped through hole, the spring is in elastic deformation, deformation cannot occur, and when the limiting rod is arranged on the upper side of the kidney-shaped through hole, the sensing block is just close to the proximity switch.

Further, in order to prevent two or more brake discs from being sucked simultaneously on the electromagnet, the device also comprises a weighing sensor arranged at the upper end of the frame. The preset value on the weighing sensor is the weight of only one brake disc on the electromagnet, when the measured value on the weighing sensor exceeds the preset value, the weighing sensor controls the electromagnet to be powered off, and then the electromagnet works again to attract the brake disc to sort.

The beneficial effects of the invention are as follows: according to the brake disc sorting gripper provided by the invention, the buffer component is arranged on the electromagnet, so that the contact area of the electromagnet and the brake disc is ensured to be large enough, the brake disc can be sucked out, and the damage caused by the rigid collision between equipment and the brake disc can be prevented.
