Description

Technical Field

[0001] The utility model relates to the technical field of grinding robots, in particular to a grinding robot with flexible counterweight. Background Art

[0002] When a grinding robot is operating, the weight distribution of its various parts may be uneven, resulting in unnecessary vibrations or tilts during operation. The counterweight block helps achieve grinding stability during grinding work by increasing the weight of the grinding part of the robot, and avoids the imbalance of the whole machine caused by vibrations.

[0003] At present, the counterweight blocks of grinding robots are usually fixedly arranged at the grinding part, and the counterweight blocks cannot be moved, so flexible counterweight of the grinding part cannot be achieved. This will cause that when the grinding object is too hard and the grinding part is pushed upward, since the grinding part is pressed by the counterweight block and cannot move upward, there is no buffer room, which will break the connecting part between the grinding part and the main body; the fixed arrangement of the counterweight block at the grinding part will also cause the grinding robot to be unable to lift the grinding part to a high enough position during movement, so that the grinding part will rub against the ground during movement, greatly accelerating the wear speed of the grinding parts of the grinding part and reducing the service life of the grinding parts. Summary of the Utility Model

[0004] Aiming at the above defects, the purpose of the utility model is to provide a grinding robot with flexible counterweight, in which the counterweight part can flexibly counterweight the grinding part and the main body, extend the service life of the grinding parts, and effectively avoid the breakage or damage of the connecting part.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] A grinding robot with flexible counterweight, comprising a grinding part, a connecting part, a main body and a counterweight part; the front parts of the grinding part and the main body are movably connected through the connecting part, one end of the counterweight part is movably connected with the main body, and the other end of the counterweight part freely moves between the connecting part and the main body;

[0007] When the other end of the counterweight part abuts against the connecting part, the other end of the counterweight part is in sliding contact with the connecting part and restricts the movement of the grinding part.

[0008] Furthermore, the number of the counterweight parts is two, and the two counterweight parts are respectively arranged on the left and right sides of the main body. One end of the counterweight part is axially connected with the left or right side of the main body, and the other end of the counterweight part swings back and forth between the top surface of the connecting part and the main body.

[0009] Furthermore, sliding parts are respectively arranged on the left and right sides of the connecting part corresponding to the counterweight parts; the sliding parts are used for abutting against the other ends of the counterweight parts.

[0010] Further, the sliding member is a roller that rolls back and forth.

[0011] Further, the counterweight portion includes a swing rod and a gravity block; one end of the swing rod is axially connected to the left or right side of the main body, the other end of the swing rod is fixedly connected to the gravity block, and the gravity block swings back and forth between the top surface of the connecting portion and the main body.

[0012] Further, load-bearing strip stoppers are respectively provided on the left and right sides of the main body corresponding to the gravity block, and the gravity block swings back and forth between the top surface of the connecting portion and the top surface of the load-bearing strip stoppers.

[0013] Further, the gravity block is also provided with a swing pull ring.

[0014] Further, the connecting portion includes a grinding mounting frame, load-bearing brackets are respectively provided on the left and right sides of the grinding mounting frame, and the sliding member is arranged on the load-bearing brackets.

[0015] The technical solution provided by the present utility model may include the following beneficial effects: The grinding portion and the front part of the main body are movably connected through the connecting portion, so that the main body can control the grinding portion to perform moving actions through the connecting portion, such as raising the grinding portion or lowering the grinding portion; then, one end of the counterweight portion is movably connected to the main body, so that the other end of the counterweight portion freely moves between the connecting portion and the main body; when the other end of the counterweight portion abuts against the connecting portion, the other end of the counterweight portion is in sliding contact with the connecting portion, and the weight of the counterweight portion itself is used to press the connecting portion tightly, so that the movable connection relationship of the connecting portion is restricted and cannot move randomly, thereby restricting other moving actions of the grinding portion during the grinding work, such as being lifted by the object to be ground, shaking along with the grinding action, etc., improving the grinding stability; and because the other end of the counterweight portion freely moves between the connecting portion and the main body, and the other end of the counterweight portion is in sliding contact with the connecting portion, when the hardness of the grinding object is too high and the upward lifting force exceeds the gravity of the counterweight portion on the connecting portion, the other end of the counterweight portion will be appropriately lifted, but still maintain the pressing state on the connecting portion, thereby using the counterweight portion to flexibly press the grinding portion, effectively avoiding the connecting portion from being broken or damaged due to the excessive hardness of the grinding object and being unable to move.

[0016] More importantly, when the grinding robot does not need to perform grinding work, the other end of the counterweight portion can be moved to the main body for placement, so that the grinding portion can be lifted off the ground by a certain height through the connecting portion, avoiding the grinding member of the grinding portion from rubbing against the ground during the movement of the grinding robot, reducing the service life of the grinding member, and at the same time, because the other end of the counterweight portion is placed on the main body, the weight of the main body is increased, which can ensure that the main body will not lose balance and tilt forward due to the elevation of the grinding portion; thus, the counterweight portion can flexibly balance the grinding portion and the main body.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.

[0026] The following will describe a grinding robot with flexible counterweight according to an embodiment of the present utility model in conjunction with Figures 1 to 4 ,

[0027] A grinding robot with flexible counterweight includes a grinding part 1, a connecting part 2, a main body 3, and a counterweight part 4; the front part of the grinding part 1 and the main body 3 are movably connected through the connecting part 2, one end of the counterweight part 4 is movably connected to the main body 3, and the other end of the counterweight part 4 freely moves between the connecting part 2 and the main body 3;

[0028] When the other end of the counterweight part 4 abuts against the connecting part 2, the other end of the counterweight part 4 is in sliding contact with the connecting part 2 and restricts the movement of the grinding part 1.

[0029] In a preferred embodiment of the grinding robot with flexible counterweight proposed by the present utility model, as Figures 1 to 4 shown, the front part of the grinding part 1 and the main body 3 are movably connected through the connecting part 2, so that the main body 3 can control the grinding part 1 to perform movement actions through the connecting part 2, such as raising the grinding part 1 or lowering the grinding part 1; then, one end of the counterweight part 4 is movably connected to the main body 3, so that the other end of the counterweight part 4 freely moves between the connecting part 2 and the main body 3; when the other end of the counterweight part 4 abuts against the connecting part 2, the other end of the counterweight part 4 is in sliding contact with the connecting part 2, and the weight of the counterweight part 4 itself is used to press the connecting part 2 tightly, so that the movable connection relationship of the connecting part 2 is restricted and cannot move freely, thereby restricting other movement actions of the grinding part 1 during the grinding work, such as being lifted by the object to be ground or shaking during the grinding action, improving the grinding stability; and because the other end of the counterweight part 4 freely moves between the connecting part 2 and the main body 3, and the other end of the counterweight part 4 is in sliding contact with the connecting part 2, when the hardness of the grinding object is too high and the upward lifting force exceeds the gravity of the counterweight part 4 on the connecting part 2, the other end of the counterweight part 4 will be appropriately lifted, but still keep pressing the connecting part 2, so as to apply flexible pressure to the grinding part 1 by the counterweight part 4, effectively avoiding the connecting part 2 from being broken or damaged due to the too large hardness of the grinding object and being unable to move.

[0030] More importantly, when the grinding robot does not need to perform grinding work, the other end of the counterweight part 4 can be moved to the main body 3 for placement, so that the grinding part 1 can be lifted off the ground by a certain height through the connecting part 2, avoiding the friction between the grinding parts of the grinding part 1 and the ground during the movement of the grinding robot, reducing the service life of the grinding parts. At the same time, because the other end of the counterweight part 4 is placed on the main body 3, the weight of the main body 3 is increased, ensuring that the main body 3 will not lose balance and tilt forward due to the elevation of the grinding part 1; thus, the counterweight part 4 can flexibly counterweight the grinding part 1 and the main body 3.

[0031] Furthermore, the number of the counterweight parts 4 is two, and the two counterweight parts 4 are respectively arranged on the left and right sides of the main body 3. One end of the counterweight part 4 is axially connected to the left or right side of the main body 3, and the other end of the counterweight part 4 swings back and forth between the top surface of the connecting part 2 and the main body 3.

[0032] In this embodiment, in order to facilitate the operation of the counterweight part 4 and keep the center of gravity of the grinding robot centered after the counterweight part 4 is set, a counterweight part 4 is respectively arranged on the left and right sides of the main body 3, and one end of the counterweight part 4 of the main body 3 is axially connected to the left or right side of the main body 3. Thus, the other end of the counterweight part 4 of the main body 3 can rotate through the shaft and swing back and forth between the top surface of the connecting part 2 of the main body 3 and the main body 3 to realize counterweight for the grinding part 1 or the main body 3.

[0033] Furthermore, sliding parts 21 are respectively arranged on the left and right sides of the connecting part 2 corresponding to the counterweight parts 4; the sliding parts 21 are used for abutting against the other end of the counterweight part 4.

[0034] In this embodiment, in order to enable the connecting part 2 and the other end of the counterweight part 4 to be in sliding contact, sliding parts 21 are respectively arranged on the left and right sides of the connecting part 2 corresponding to the counterweight parts 4. When the other end of the counterweight part 4 abuts against the sliding parts 21, if the force in the horizontal direction exceeds the gravity applied by the other end of the counterweight part 4, by using the slidable characteristic of the sliding parts 21 themselves, the other end of the counterweight part 4 and the connecting part 2 can slide relative to each other, avoiding the connecting part 2 from being broken or damaged due to excessive force in the horizontal direction.

[0035] Furthermore, the sliding parts 21 are rollers that roll back and forth.

[0036] In this embodiment, during the grinding work and movement of the grinding robot, more forces are received in the front and back directions. Therefore, the sliding parts 21 are preferably rollers that roll back and forth.

[0037] Furthermore, the counterweight part 4 includes a swing rod 41 and a gravity block 42; one end of the swing rod 41 is axially connected to the left or right side of the main body 3, the other end of the swing rod 41 is fixedly connected to the gravity block 42, and the gravity block 42 swings back and forth between the top surface of the connecting part 2 and the main body 3.

[0038] In this embodiment, the counterweight part 4 should concentrate the weight on the part applied to the connecting part 2, so it is composed of a swing rod 41 and a gravity block 42. One end of the swing rod 41 is axially connected to the left or right side of the main body 3, and the other end of the swing rod 41 is fixedly connected to the gravity block 42. The gravity block 42 swings back and forth between the top surface of the connecting part 2 and the main body 3, applying pressure to the top surface of the connecting part 2 respectively to press the grinding part 1, and applying pressure to the main body 3 to increase the weight of the main body 3.

[0039] Further, load-bearing strip stoppers 11 are respectively provided on the left and right sides of the main body 3 corresponding to the gravity block 42, and the gravity block 42 swings back and forth between the top surface of the connecting part 2 and the top surface of the load-bearing strip stoppers 11.

[0040] In this embodiment, in order for the main body 3 to better bear the weight of the gravity block 42 and to prevent the gravity block 42 from swinging excessively and contacting the bottom surface, load-bearing strip stoppers 11 are respectively provided on the left and right sides of the main body 3 corresponding to the gravity block 42, and the gravity block 42 swings back and forth between the top surface of the connecting part 2 and the top surface of the load-bearing strip stoppers 11.

[0041] Further, a swing pull ring 43 is also provided on the gravity block 42.

[0042] In this embodiment, the swing of the counterweight part 4 is usually manually operated. In order to facilitate the operator to move the gravity block 42 to achieve swinging, a swing pull ring 43 is provided on the gravity block 42.

[0043] Further, the connecting part 2 includes a grinding mounting frame 22. Load-bearing brackets 23 are respectively provided on the left and right sides of the grinding mounting frame 22, and the sliding member 21 is arranged on the load-bearing brackets 23.

[0044] In this embodiment, in order for the connecting part 2 to better bear the weight of the gravity block 42 and apply pressure to the grinding part 1, it is preferably to respectively provide load-bearing brackets 23 on the left and right sides of the grinding mounting frame 22 for mounting the grinding part 1, and then arrange the sliding member 21 on the load-bearing brackets 23. Thus, when the sliding member 21 contacts the gravity block 42, pressure is applied to the grinding part 1 through the load-bearing brackets 23.

[0045] For other components and operations of the grinding robot with flexible counterweight according to the embodiments of the present invention, etc. are known to those of ordinary skill in the art, and will not be described in detail here.

[0046] In the description of this specification, the description with reference to terms such as "embodiment", "example", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
