Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a robotic arm with positioning function. Background Technology

[0002] In construction projects, there is a need to move construction materials and equipment. With the development of technology, robotic arms are now used to replace manual labor in moving operations, which greatly improves the efficiency and safety of moving work.

[0003] Traditional robotic arms typically consist of a fixed base, a lifting mechanism, and a gripping device, enabling basic material handling. However, during unloading, because the direction and position of the robotic arm are fixed, operators need to frequently move the entire device to adapt to different unloading directions and positions, resulting in low work efficiency. Therefore, we propose a robotic arm with positioning function. Utility Model Content

[0004] This invention solves the problem of low work efficiency caused by operators having to frequently move the entire equipment to adapt to different unloading directions and positions. Therefore, it provides a robotic arm with positioning function.

[0005] This utility model is achieved using the following technical solution: a robotic arm with positioning function, including a base plate, a universal wheel fixedly connected to the bottom of the base plate, a rotating assembly provided at the upper end of the base plate, a lifting assembly provided at the upper end of the rotating assembly, an adjusting assembly provided at the right end of the lifting assembly, a hydraulic rod fixedly connected to the top of the base plate, the output end of the hydraulic rod penetrating the base plate and fixedly connected to a fixing plate, a limit rod fixedly connected to the top of the fixing plate, and an annular groove formed on the upper surface of the base plate;

[0006] The rotating assembly includes a top plate, a support rod fixedly connected to the bottom of the top plate, a U-shaped plate fixedly connected to the bottom of the support rod, ball bearings fixedly connected to the inner wall of the U-shaped plate, a fixed column fixedly connected to the bottom of the top plate, a driven gear fixedly connected to the surface of the fixed column, a driving gear meshing with the inner wall of the driven gear, a transmission rod fixedly connected to the inner wall of the driving gear, and a first motor fixedly connected to the bottom of the transmission rod.

[0007] Through the above technical solution, the first motor drives the transmission rod to rotate, causing the drive gear to rotate. Since the drive gear and the driven gear mesh with each other, the fixed column rotates, which in turn drives the top plate to rotate, adjusting the position of the adjustment component. This facilitates unloading in different directions, improving work efficiency. Furthermore, when the top plate rotates, the balls on the inner wall of the U-shaped plate slide along the annular groove, providing support and limiting for the top plate, thus improving stability when adjusting the direction.

[0008] As a further improvement to the above solution, the surface of the ball is slidably connected to the inner wall of the annular groove, the bottom of the fixed column is rotatably connected to the inner wall of the base plate, the bottom of the first motor is fixedly connected to the top of the base plate, and the surface of the limiting rod is slidably connected to the inner wall of the base plate.

[0009] The above technical solution incorporates four support rods, four U-shaped plates, and four ball bearings, which improves the limiting effect and support stability. The limiting rods also limit the position of the fixed plate, ensuring the accuracy of adjustment.

[0010] As a further improvement to the above solution, the lifting assembly includes a fixed frame, a second motor is fixedly connected to the top of the fixed frame, a lead screw is fixedly connected to the output end of the second motor, and a mounting base is threaded onto the surface of the lead screw.

[0011] The above technical solution involves using a second motor to drive a lead screw to rotate, which in turn moves the mounting base, thereby adjusting the height of the adjustment component.

[0012] As a further improvement to the above solution, the bottom of the fixing frame is fixedly connected to the top of the top plate, the two ends of the lead screw are rotatably connected to the inner wall of the fixing frame, and the surface of the mounting base is slidably connected to the inner wall of the fixing frame.

[0013] Through the above technical solution, the mounting base is slidably connected to the inner wall of the fixed frame, thereby limiting the mounting base and ensuring the stability of the mounting base when it moves.

[0014] As a further improvement to the above solution, the adjustment component includes an extension plate, a mounting bracket slidably connected to the surface of the extension plate, a third motor fixedly connected to the front end of the mounting bracket, a fixing rod fixedly connected to the output end of the third motor, a gear fixedly connected to the surface of the fixing rod, a rack fixedly connected to the bottom of the extension plate, a mounting plate fixedly connected to the bottom of the mounting bracket, an electric push rod fixedly connected to the bottom of the mounting plate, and a robotic arm fixedly connected to the output end of the electric push rod.

[0015] Through the above technical solution, the fixed rod is driven to rotate by the third motor, which in turn causes the gear to rotate. Since the gear meshes with the rack, the mounting frame moves along the extension plate, adjusting the position of the robot arm. This facilitates the clamping of materials in different positions and improves the flexibility of use. The robot arm is composed of a motor, a lead screw, and a clamping plate.

[0016] As a further improvement to the above solution, the left end of the extension plate is fixedly connected to the right end of the mounting base.

[0017] With the above technical solution, since the extension plate is fixedly connected to the mounting base, the extension plate will be raised and lowered when the mounting base moves.

[0018] As a further improvement to the above solution, the surface of the fixing rod is rotatably connected to the inner wall of the mounting bracket, and the gear and rack mesh with each other.

[0019] The above technical solution uses a fixed rod to support the gear. Since the rack is fixedly connected to the top of the extension plate, the extension plate will slide and adjust along the mounting frame when the gear rotates.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) By setting a rotating component, specifically by driving the transmission rod to rotate through the first motor, the driving gear rotates. Since the driving gear and the driven gear mesh with each other, the fixed column rotates, driving the top plate to rotate, adjusting the position of the adjustment component, which facilitates unloading in different directions and improves work efficiency. When the top plate rotates, the balls on the inner wall of the U-shaped plate slide along the annular groove, which supports and limits the top plate, improving the stability when adjusting the direction.

[0022] (2) By setting an adjustment component, specifically by driving the fixed rod to rotate through the third motor, the gear rotates. Since the gear meshes with the rack, the mounting frame moves along the extension plate, adjusting the position of the robot arm, which facilitates clamping materials at different positions and improves the flexibility of use.

An annular groove 9 is provided on the upper surface of the base plate 1.

[0033] The rotating assembly 3 includes a top plate 301, a support rod 302 fixedly connected to the bottom of the top plate 301, a U-shaped plate 303 fixedly connected to the bottom of the support rod 302, a ball bearing 304 fixedly connected to the inner wall of the U-shaped plate 303, a fixed column 305 fixedly connected to the bottom of the top plate 301, a driven gear 306 fixedly connected to the surface of the fixed column 305, a driving gear 307 meshing with the inner wall of the driven gear 306, a transmission rod 308 fixedly connected to the inner wall of the driving gear 307, and a first motor 309 fixedly connected to the bottom of the transmission rod 308. When unloading in different directions is required, the first motor 309 is started, which drives the transmission rod 308 to rotate, causing the driving gear 307 to rotate. Since the driving gear 307 and the driven gear 306 mesh with each other, the fixed column 305 rotates, driving the top plate 301 to rotate, adjusting the position of the adjusting assembly 5, facilitating unloading in different directions, and improving work efficiency.

[0034] The surface of the ball bearing 304 is slidably connected to the inner wall of the annular groove 9, the bottom of the fixed column 305 is rotatably connected to the inner wall of the base plate 1, the bottom of the first motor 309 is fixedly connected to the top of the base plate 1, the surface of the limiting rod 8 is slidably connected to the inner wall of the base plate 1, and when the top plate 301 rotates, the ball bearing 304 on the inner wall of the U-shaped plate 303 will slide along the annular groove 9, which will support and limit the top plate 301, thus improving the stability when adjusting the direction.

[0035] The lifting assembly 4 includes a fixed frame 401, a second motor 402 is fixedly connected to the top of the fixed frame 401, a lead screw 403 is fixedly connected to the output end of the second motor 402, and a mounting base 404 is threadedly connected to the surface of the lead screw 403. The second motor 402 drives the lead screw 403 to rotate, causing the mounting base 404 to slide along the inner wall of the fixed frame 401, thereby adjusting the height of the adjusting assembly 5.

[0036] The bottom of the fixed frame 401 is fixedly connected to the top of the top plate 301, the two ends of the screw 403 are rotatably connected to the inner wall of the fixed frame 401, and the surface of the mounting base 404 is slidably connected to the inner wall of the fixed frame 401.

[0037] The adjustment assembly 5 includes an extension plate 501, a mounting bracket 502 slidably connected to the surface of the extension plate 501, a third motor 503 fixedly connected to the front end of the mounting bracket 502, a fixed rod 504 fixedly connected to the output end of the third motor 503, a gear 505 fixedly connected to the surface of the fixed rod 504, a rack 506 fixedly connected to the bottom of the extension plate 501, a mounting plate 507 fixedly connected to the bottom of the mounting bracket 502, an electric push rod 508 fixedly connected to the bottom of the mounting plate 507, and a robot arm 509 fixedly connected to the output end of the electric push rod 508. When the position of the robot arm 509 needs to be adjusted, the third motor 503 is started, which drives the fixed rod 504 to rotate, causing the gear 505 to rotate. Since the gear 505 meshes with the rack 506, the mounting bracket 502 moves along the extension plate 501, adjusting the position of the robot arm 509, which facilitates the clamping of materials at different positions and improves the flexibility of use.

[0038] The left end of the extension plate 501 is fixedly connected to the right end of the mounting base 404.

[0039] The surface of the fixing rod 504 is rotatably connected to the inner wall of the mounting bracket 502, and the gear 505 meshes with the rack 506.

[0040] The implementation principle of a robotic arm with positioning function in this application embodiment is as follows: when in use, the whole body is moved to the use position by the universal wheel 2, and then the hydraulic rod 6 is activated. The output end of the hydraulic rod 6 pushes the fixed plate 7 to move downward. The fixed plate 7 contacts the ground to increase the friction force, avoid the whole body from moving accidentally, achieve the positioning effect, and ensure the stability during use.

[0042] When the position of the robotic arm 509 needs to be adjusted, the third motor 503 is started. The third motor 503 drives the fixed rod 504 to rotate, causing the gear 505 to rotate. Since the gear 505 meshes with the rack 506, the mounting frame 502 moves along the extension plate 501 to adjust the position of the robotic arm 509, which facilitates the clamping of materials in different positions and improves the flexibility of use. When clamping materials, the robotic arm 509 is pushed downward by the electric push rod 508 to clamp the materials.

[0043] When unloading is required in different directions, the first motor 309 is started. The first motor 309 drives the transmission rod 308 to rotate, which causes the drive gear 307 to rotate. Since the drive gear 307 and the driven gear 306 mesh with each other, the fixed column 305 rotates, which drives the top plate 301 to rotate, adjusting the position of the adjustment component 5. This facilitates unloading in different directions, improves work efficiency, and when the top plate 301 rotates, the ball bearings 304 on the inner wall of the U-shaped plate 303 slide along the annular groove 9, which supports and limits the top plate 301, improving stability when adjusting the direction.
