Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.

Referring to fig. 1 to 7, the embodiment provides an industrial robot protection device, which can protect the joint between a mechanical arm and a dust cover, and meanwhile, continuous research is still needed to avoid paint falling due to abrasion of the mechanical arm.

Including the dust cover 30, the outside of arm is located in the cover of dust cover 30 is used for sheltering from the rotation junction of two arms, the cross sectional shape of dust cover 30 is the U type, and dust cover 30 can dismantle with the arm and be connected, still including the lining cloth 10 that is used for wrapping up the arm, in the course of the work, lining cloth 10 is located between the interior anchor ring of dust cover and the arm, be equipped with on the lining cloth 10 and be used for the restriction dust cover 30 is at the spacing subassembly of the axial displacement in the arm outside, be equipped with dull polish face 12 on the lateral surface of lining cloth 10, be equipped with on the medial surface of lining cloth 10 and be used for connecting the hook hair face 11 of dull polish face 12, still be equipped with attached piece 13 that is used for connecting the arm on the medial surface of lining cloth 10, for avoiding attached piece 13 to damage the outer lacquer of arm, be convenient for separating simultaneously and attach piece 13 and arm, attached piece 13 is preferred to be electrostatic subsides.

When in use: attaching the attaching piece 13 to the mechanical arm near the joint of two adjacent mechanical arms, manually stretching the lining cloth 10 to enable the lining cloth 10 to be tightly wound on the outer side of the mechanical arm due to the attaching piece 13 attached to the mechanical arm, and then connecting the hook rough surface 11 and the sanding surface 12; repeating the above operations, winding the lining cloth 10 on the outer sides of the two adjacent mechanical arms, and fixing the lining cloth 10 on the outer sides of the two adjacent mechanical arms;

install a plurality of dust covers 30 in the outside of lining cloth 10, because lining cloth 10 wraps up in the outside of arm this moment, the arm rotates the in-process, because the piece 13 that attaches is attached on the arm, lining cloth 10 is fixed for the arm, and the interior anchor ring face of dust cover and lining cloth 10 rotate the friction relatively, and then has protected the arm, has effectively prevented the unnecessary wearing and tearing of arm.

As shown in fig. 1 and 4, in order to reduce the abrasion between the dust cover 30 and the lining cloth 10, the ends of both sides of the U-shape of the dust cover 30 are folded outward to form the ring part 31.

When in use: due to the arrangement of the annular part 31, the contact area between the dust cover 30 and the lining cloth 10 is increased, and under the premise that the mass of the dust cover 30 is not changed, the pressure between the dust cover 30 and the lining cloth 10 is reduced, and the abrasion degree between the dust cover 30 and the lining cloth 10 is weakened.

Referring to fig. 2, 3 and 4, in order to limit the axial movement of the dust cover 30 at the outer side of the robot arm, the limiting assembly includes a blocking strip 20 fixed on the side edge of the lining cloth 10 for limiting the axial movement of the dust cover 30, the height of the blocking strip 20 is greater than the thickness of the lining cloth 10, and the side edge where the hook burr 11 and the attachment piece 13 are located is adjacent to the side edge where the blocking strip 20 is located.

When in use: the lining cloth 10 wraps the mechanical arm, the barrier strip 20 is located on the inner side of the U-shaped dust cover 30, the inner ring surface of the dust cover 30 is abutted to the lining cloth 10, and due to the fact that the height of the barrier strip 20 is larger than the thickness of the lining cloth 10, in the rotating process of the mechanical arm, the dust cover 30 can only rotate on the outer side of the mechanical arm, and cannot move axially on the outer side of the mechanical arm.

As shown in fig. 4 and 7, in order to prevent the end-to-end connection of the barrier strip 20 from being loosened, a plurality of ratchets 23 are arranged inside the connecting groove 21, a push rod 24 is arranged on the connecting strip 22, the push rod 24 is slidably connected with the connecting strip 22, an elastic ball 27 for driving the push rod 24 to be located between the adjacent ratchets 23 is further arranged on the connecting strip 22, a stopper 25 is fixedly arranged on the push rod 24, a sliding groove 26 is arranged on the connecting strip 22, the stopper 25 is slidably connected with the sliding groove 26, and the elastic ball 27 is arranged inside the sliding groove 26 and used for applying a driving force to the stopper 25.

When in use: the utility model discloses a manual pulling push rod 24, push rod 24 drives dog 25 and removes, elastic ball 27 compresses, manual removal blend stop 20 makes connecting strip 22 slide in inside spread groove 21, after connecting strip 22 is convoluteed completely in the outside of arm, release push rod 24, elastic ball 27 resets, elastic ball 27 passes through dog 25 drive push rod 24 and gets into between two adjacent ratchets 23, when annular cover rotates for the arm, annular cover and blend stop 20 can take place the friction, because ratchet 23 is to the restriction of push rod 24, connecting strip 22 can't slide in the inside of spread groove 21, thereby effectively avoided annular cover to drive the separation of blend stop 20 and arm and make it can't continue to carry on spacingly to annular cover at the rotation in-process.

As shown in fig. 4 and 7, in order to further prevent the end-to-end connection of the barrier strip 20 from being loosened, the ratchet 23 is wedge-shaped, the ratchet 23 includes a sliding guide part for pushing the push rod 24 to slide vertically and a limiting part for limiting the push rod 24 to slide laterally, and the sliding guide part and the limiting part are oppositely arranged in the length direction of the barrier strip 20.

When in use: because an acting force along the radial direction of the mechanical arm is applied to the connecting bar 22 when the push rod 24 is pulled manually, a gap exists between the connecting bar 22 and the mechanical arm, so that a gap exists between the connecting bar 22 and the mechanical arm when the push rod 24 is released, the ratchets 23 are set to be wedge-shaped, when the barrier bar 20 is moved manually, the connecting bar 22 slides upwards under the action of the guide sliding part of the ratchets 23 in the internal sliding process of the connecting bar 22, when the push rod 24 moves to a position between two ratchets 23 again, the elastic ball 27 resets, the stopper 25 drives the push rod 24 to re-enter between two adjacent ratchets 23 under the action of the elastic ball 27, and due to the limitation of the limiting part on the push rod 24, the reverse sliding of the connecting bar 22 under the action of the elastic force of the stopper 22 is avoided, so that the connecting bar 22 is tightly attached to the mechanical arm, and in the rotating process of the annular cover, the connecting bar 22 only absorbs the kinetic energy of the unidirectional rotation of the annular cover, so that the annular cover 22 is tightly attached to the mechanical arm, and the annular cover cannot be continuously limited.

The above is only the typical example of the utility model, in addition, the utility model discloses can also have other multiple detailed implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall on the utility model discloses the scope of requiring protection.
