Description

Technical Field

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

[0002] At present, grinding robots often use the self - gravity of their grinding parts to press and grind the grinding objects. However, since the connection between the grinding part and the main body is relatively fixed without the main body controlling the rise or fall of the grinding part, when grinding objects with too high hardness, it is impossible to use the connection between the grinding part and the main body to move and buffer to a certain extent. It can only continue to press the grinding object for grinding, resulting in a too violent grinding process, flying debris, and the grinding part shaking violently due to the excessive hardness of the grinding object, thus leading to unstable grinding, poor grinding effect of the grinding object, and even possible tipping over of the grinding robot due to the excessive hardness and large shaking of the grinding object. Content of the Utility Model

[0003] Aiming at the above - mentioned defects, the purpose of the utility model is to provide a grinding robot with stable grinding, which uses a buffer part to buffer and move to accommodate the shaking of the grinding part, making the grinding process more stable and the grinding effect better.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A grinding robot with stable grinding, comprising a grinding part, a connecting part, a transmission part, a main body and a buffer part; the grinding part is installed at the front of the connecting part, the rear of the connecting part is movably connected to the front of the main body, one end of the transmission part is movably connected to the front top of the main body, the other end of the transmission part is movably connected to the top of the buffer part, and the bottom of the buffer part is movably connected to the connecting part.

[0006] Further, the buffer part includes a fixing part and a buffer connecting part; the bottom of the fixing part is fixed to the connecting part, the top of the fixing part is axially connected to the bottom of the buffer connecting part, one end of the transmission part is axially connected to the front top of the main body, and the top of the buffer connecting part is axially connected to the other end of the transmission part.

[0007] Further, a first axial connection groove is formed from front to back at the top of the buffer connecting part, and a second axial connection groove is formed from front to back at the bottom of the buffer connecting part;

[0008] The other end of the transmission part is axially connected to the top of the buffer connecting part in the first axial connection groove;

[0009] The top of the fixing part is axially connected to the bottom of the buffer connecting part in the second axial connection groove.

[0010] Further, a limiting strip is provided in front of the shaft connection part in the second shaft connection groove.

[0011] Further, the connecting part includes a grinding mounting frame and a connecting rod; the grinding part is mounted on the front part of the grinding mounting frame, and an activity shaft and a transmission support are horizontally arranged at the rear part of the grinding mounting frame from left to right. The grinding mounting frame is axially connected to the front bottom part of the main body through the activity shaft. One end of the connecting rod is axially connected to the center of the activity shaft, the other end of the connecting rod is fixedly connected to the front top part of the main body, and the bottom of the fixing part is fixed to the center of the transmission support.

[0012] Further, the transmission support is arranged in front of the activity shaft.

[0013] Further, a limiting groove is provided at the bottom of the fixing part, a fixing rod is provided at the center of the limiting groove, and a through hole is provided on the transmission support corresponding to the fixing rod;

[0016] The technical solution provided by the present utility model may include the following beneficial effects: The main body can drive the transmission part to move, link the connecting part, and thus drive the grinding part to move. For example, when the transmission part is a pneumatic telescopic cylinder, it can drive the connecting part to rise and fall through pneumatic expansion and contraction, thereby driving the grinding part to rise and fall. On this basis, since a buffer part is connected between the transmission part and the connecting part, when the grinding part completes the lifting and lowering movement and presses the grinding object to start grinding, in order to maintain the pressing state on the grinding object, the transmission part basically remains stationary. At this time, if the hardness of the grinding object is too large and the grinding process is too intense, the grinding part will vibrate and be lifted by the grinding object, then the buffer part will move accordingly, so that the connecting part uses the buffer part to buffer and move within a certain range without the movement of the transmission part, thereby catering to the vibration of the grinding part, and further making the grinding process more stable, the grinding effect better, and the vibration will not be transmitted to the main body to avoid tipping over.

[0028] Combine the following Figures 1 to 6 , describing a grinding robot with stable grinding according to an embodiment of the utility model.

[0029] A grinding robot with stable grinding comprises a grinding part 1, a connecting part 2, a transmission part 3, a main body 4 and a buffer part 5; the grinding part 1 is installed on the front part of the connecting part 2, the rear part of the connecting part 2 is movably connected to the front part of the main body 4, one end of the transmission part 3 is movably connected to the front top of the main body 4, the other end of the transmission part 3 is movably connected to the top of the buffer part 5, and the bottom of the buffer part 5 is movably connected to the connecting part 2.

[0030] The utility model proposes a preferred embodiment of a grinding robot for stable grinding, such as Figures 1 to 6 As shown, the main body 4 can move by driving the transmission part 3, linking the connecting part 2, thereby driving the grinding part 1 to move; for example, the transmission part 3 is a pneumatic telescopic cylinder, which can be pneumatically extended and extended to link the connecting part 2 to rise and fall, thereby driving the grinding part 1 to rise and fall. On this basis, since a buffer part 5 is connected between the transmission part 3 and the connecting part 2, when the lifting and lowering movement of the grinding part 1 is completed, the grinding part 1 presses the grinding object to start grinding, in order to maintain the pressing state of the grinding object, the transmission part 3 basically remains motionless. At this time, if the hardness of the grinding object is too large and the grinding process is too intense, the grinding part 1 will shake and be lifted up by the grinding object, and the buffer part 5 will move accordingly, so that when the transmission part 3 is stationary, the connecting part 2 uses the buffer part 5 to buffer the movement within a certain range, thereby catering to the shaking of the grinding part 1, and then the grinding process is more stable, the grinding effect is better, and the shaking will not be transmitted to the main body 4 to avoid rollover.

[0031] Furthermore, the buffer part 5 includes a fixing part 51 and a buffer connecting part 52; the bottom of the fixing part 51 is fixed to the connecting part 2, the top of the fixing part 51 is axially connected to the bottom of the buffer connecting part 52, one end of the transmission part 3 is axially connected to the front top of the main body 4, and the top of the buffer connecting part 52 is axially connected to the other end of the transmission part 3.

[0032] In this embodiment, the grinding part 1 of the grinding robot is usually only driven to move up and down. Therefore, the fixing part 51, the buffer connecting part 52, the transmission part 3 and the main body 4 are sequentially connected by shafts to meet the requirements of the lifting movement. And when there is grinding jitter, only the buffer connecting part 52 can make the fixing part 51 and the transmission part 3 move out of position, realizing buffer movement and catering to the jitter of the grinding part 1.

[0033] Further, a first shaft connection groove 521 is formed in the top of the buffer connecting part 52 from front to back, and a second shaft connection groove 522 is formed in the bottom of the buffer connecting part 52 from front to back.

[0034] The other end of the transmission part 3 is shaft-connected to the top of the buffer connecting part 52 in the first shaft connection groove 521.

[0035] The top of the fixing part 51 is shaft-connected to the bottom of the buffer connecting part 52 in the second shaft connection groove 522.

[0036] In this embodiment, in order to make the buffering effect of the buffer connecting part 52 better and the other end of the transmission part 3 and the top of the fixing part 51 have sufficient rotation space, both the top of the buffer connecting part 52 and the bottom of the buffer connecting part 52 are set as groove bodies, and rotation is carried out by using the space in the groove, so that the misalignment amplitude between the other end of the transmission part 3 and the top of the fixing part 51 is larger.

[0037] Further, a limiting strip 523 is provided in front of the shaft connection in the second shaft connection groove 522.

[0038] In this embodiment, to avoid the misalignment direction of the other end of the transmission part 3 and the top of the fixing part 51 being incorrect, resulting in the other end of the transmission part 3 and the top of the fixing part 51 moving forward out of position, and pressing the grinding part 1 down further by the connecting part 2, which has a counterproductive effect, a limiting strip 523 is provided in front of the shaft connection in the second shaft connection groove 522.

[0039] Further, the connecting part 2 includes a grinding mounting frame 21 and a connecting rod 22; the grinding part 1 is mounted on the front part of the grinding mounting frame 21. A movable shaft 211 and a transmission bracket 212 are horizontally arranged from left to right at the rear part of the grinding mounting frame 21. The grinding mounting frame 21 is shaft-connected to the front bottom of the main body 4 through the movable shaft 211. One end of the connecting rod 22 is shaft-connected to the center of the movable shaft 211, the other end of the connecting rod 22 is fixedly connected to the front top of the main body 4, and the bottom of the fixing part 51 is fixed to the center of the transmission bracket 212.

[0040] In this embodiment, the grinding mounting frame 21 is connected to the front bottom shaft of the main body 4 through the movable shaft 211. One end of the connecting rod 22 is pivotally connected to the center of the movable shaft 211, and the other end of the connecting rod 22 is fixedly connected to the front top of the main body 4, providing support for the grinding part 1 mounted on the front of the grinding mounting frame 21. Then, the bottom of the fixing member 51 is fixed to the center of the transmission bracket 212, enabling the transmission part 3 to be linked to the connecting part 2 to drive the grinding part 1 to move.

[0041] Furthermore, the transmission bracket 212 is arranged in front of the movable shaft 211.

[0042] In this embodiment, by arranging the transmission bracket 212 in front of the movable shaft 211, the grinding mounting frame 21, the connecting rod 22, the fixing member 51, and the buffer connecting member 52 form an approximate triangular relative position relationship, providing better support for the grinding part 1 mounted on the front of the grinding mounting frame 21. At the same time, it is more convenient for the transmission part 3 to be linked to the connecting part 2 to drive the grinding part 1 to move.

[0043] Furthermore, a limiting groove 511 is provided at the bottom of the fixing member 51, and a fixing rod 512 is provided at the center of the limiting groove 511. The transmission bracket 212 is provided with a through hole corresponding to the fixing rod 512.

[0044] The limiting groove 511 is sleeved on the transmission bracket 212, and the fixing rod 512 passes through the through hole and cooperates with the fixing block 513 to fix the fixing member 51.

[0045] In this embodiment, the limiting groove 511 is sleeved on the transmission bracket 212, making it not easy for the top of the fixing member 51 to shift during the forward and backward transmission. Then, the fixing rod 512 (such as a screw) passes through the through hole and cooperates with the fixing block 513 (such as a wrench block with a nut in the center) to fix (such as cooperate and tighten) the fixing member 51, forming a firm fixing relationship between the fixing member 51 and the transmission bracket 212.

[0046] Furthermore, the grinding part 1 is provided with a sensor for detecting the height of the grinding part 1 from the ground.

[0047] In this embodiment, for the grinding stability of the grinding robot, the wear degree of the grinding parts of the grinding part 1 also needs to be considered. To avoid damage to the grinding part 1 caused by continuous grinding when the grinding parts are consumed, a sensor (such as a distance sensor) can be used to detect the height of the grinding part 1 from the ground, thereby obtaining the wear condition of the grinding parts. The more severely worn, the smaller the height of the grinding part 1 from the ground, and the grinding stops when the preset threshold height is reached.
