Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, and in particular to a precision lathe for processing bearings of humanoid robot reducers. Background Technology
[0002] Precision reducers and bearings are among the most valuable components in humanoid robots, and also represent areas with high manufacturing barriers. The difficulty lies in the dimensional and positional accuracy of these parts. Robot operation demands high transmission accuracy, and the machining precision of key components (such as bearing raceways and crankshafts) typically needs to reach the micrometer level. The continuous working capability (wear resistance + precision retention + lifespan) of reducers directly impacts the cost of humanoid robots, thus placing high demands on the machining of reducer and bearing components.
[0003] Therefore, it is necessary to improve the rigidity of the lathe, reduce machining deformation, and improve the machining accuracy of the bearing parts of the humanoid robot reducer. Utility Model Content
[0004] The purpose of this invention is to provide a precision lathe for machining bearings of humanoid robot reducers, in order to solve the problem of insufficient machining accuracy of existing precision lathes for machining bearings of humanoid robot reducers.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a precision lathe for machining bearings of a humanoid robot reducer, comprising a machine tool and an adjustment structure;
[0006] The machine tool has a dust collection chamber inside its top end. A fixed structure is installed on one side of the top end of the machine tool, and an adjustment structure is installed on one side of the fixed structure. The adjustment structure includes a first guide rail fixed to the top end of the machine tool, a second guide rail fixed to one side of the first guide rail, a first electric push rod fixed to the top end of the machine tool between the first and second guide rails, a sliding seat installed at the top end of the first and second guide rails, a controller installed at the top end of the sliding seat, a reducer fixed to one side of the controller, a mounting block installed at one end of the controller, a cutting tool installed on the outer side of the mounting block, a slide rail fixed to the top end of the sliding seat, a sliding plate fixed to the bottom end of the controller at the top end of the slide rail, and a second electric push rod fixed to one side of the sliding seat.
[0007] Preferably, the fixing structure includes a fixed base mounted on the top of the machine tool, a motor is fixed at one end of the fixed base, a rotating block is mounted at the other end of the fixed base, a three-jaw chuck is mounted at one end of the rotating block, and a bearing is installed inside the three-jaw chuck.
[0008] Preferably, reinforcing ribs are evenly fixed on the outer side of the fixed base, a rotating shaft is fixed to one end of the motor, one end of the rotating block is fixedly connected to the rotating shaft, and the three-jaw chuck is fixedly connected to the rotating block by bolts.
[0009] With the above structure, the three-jaw chuck can clamp the bearing during use, and the rotating block drives the three-jaw chuck to rotate, which facilitates the high-speed rotation of the bearing for processing. This helps to reduce deformation and vibration caused by uneven force, thus helping to achieve high-precision machining.
[0010] Preferably, the first guide rail and the second guide rail are symmetrically distributed at the bottom end of the sliding seat, the sliding seat is slidably connected to the first guide rail and the second guide rail respectively, and the output end of the first electric push rod is fixedly connected to one side of the sliding seat.
[0011] With the above structure, during use, the sliding seat is moved laterally by the first electric push rod, which makes it easy to adjust the tool according to the thickness of the bearing and facilitates processing.
[0012] Preferably, the controller is electrically connected to the reducer, and mounting holes are evenly provided on the outer side of the mounting block, with the cutter and the mounting block forming a locking structure through the mounting holes.
[0013] The above structure makes it easier to install the cutting tool on the mounting block during use, facilitating its replacement.
[0014] Preferably, the slide rails are symmetrically distributed at the bottom of the slide plate, the slide rails are slidably connected to the slide plate, one side of the sliding seat is inclined, and the output end of the second electric push rod is fixedly connected to one side of the slide plate.
[0015] With the above structure, during use, the second electric push rod drives the slide plate to slide downward, so that one side of the cutter comes into contact with the outer side of the bearing, which makes it easier to adjust the cutter according to the diameter of the bearing.
[0016] The present invention provides a precision lathe for machining bearings in a humanoid robot reducer, which has the following advantages:
[0017] By setting a fixed structure, the bearing is clamped by a three-jaw chuck, which makes the clamping force on the bearing evenly distributed. It can adapt to bearings of different sizes and ensure the stability of the bearing during the processing. The three-jaw chuck drives the bearing to rotate at high speed for processing, ensuring that the force on the bearing is more even. This helps to reduce deformation and vibration caused by uneven force, thus helping to achieve high-precision processing.
[0018] By incorporating an adjustment structure, the cutting tool can be moved to one side of the bearing according to its size, facilitating the machining of bearings of different sizes and ensuring the accuracy of the cutting depth. Furthermore, the tool is rotated by the mounting block, enabling a feed rate of up to 40 m / min and a repeatability of 0.003 mm, thus ensuring the accuracy of the feed rate. This allows the mounting block to drive the tool to precisely shape the complex curved surfaces of the bearing, enabling the lathe to machine high-precision dimensions and shapes that meet the requirements of humanoid robot reducer bearings.

[0026] Please see Figure 1-5 The present invention provides a precision lathe for machining bearings of reducers for humanoid robots, comprising a machine tool 1 and an adjustment structure 4.
[0027] Reference Figures 2-4As shown, a dust collection chamber 2 is provided inside the top of the machine tool 1. A fixing structure 3 is installed on one side of the top of the machine tool 1. The fixing structure 3 includes a fixing seat 301 installed on the top of the machine tool 1. A motor 302 is fixed at one end of the fixing seat 301. A rotating block 303 is installed at the other end of the fixing seat 301. A three-jaw chuck 304 is installed at one end of the rotating block 303. A bearing 305 is installed inside the three-jaw chuck 304. Reinforcing ribs are evenly fixed on the outer side of the fixing seat 301. A rotating shaft is fixed at one end of the motor 302. One end of the rotating block 303 is fixedly connected to the rotating shaft. The three-jaw chuck 304 is fixedly connected to the rotating block 303 by bolts.
[0028] The bearing 305 is clamped by the three-jaw chuck 304, which makes the clamping force on the bearing 305 evenly distributed, and can adapt to bearings 305 of different sizes. This ensures the stability of the bearing 305 during the processing. Then, by starting the motor 302, the rotating block 303 drives the three-jaw chuck 304 to rotate, which facilitates the high-speed rotation of the bearing 305 for processing. This ensures that the force on the bearing 305 is more uniform, which helps to reduce deformation and vibration caused by uneven force, thus helping to achieve high-precision processing.
[0029] Reference Figures 1-5 As shown, an adjustment structure 4 is installed on one side of the fixed structure 3. The adjustment structure 4 includes a first guide rail 401 fixed to the top of the machine tool 1, a second guide rail 402 fixed to one side of the first guide rail 401, a first electric push rod 403 fixed to the top of the machine tool 1 between the first guide rail 401 and the second guide rail 402, a sliding seat 404 installed at the top of the first guide rail 401 and the second guide rail 402, a controller 405 installed at the top of the sliding seat 404, a reducer 406 fixed to one side of the controller 405, a mounting block 407 installed at one end of the controller 405, a cutting tool 408 installed on the outer side of the mounting block 407, a slide rail 409 fixed to the top of the sliding seat 404, a slide plate 410 fixed to the bottom end of the controller 405 at the top of the slide rail 409, and a slide... A second electric push rod 411 is fixed to one side of the moving seat 404. The first guide rail 401 and the second guide rail 402 are symmetrically distributed at the bottom of the sliding seat 404. The sliding seat 404 is slidably connected to the first guide rail 401 and the second guide rail 402 respectively. The output of the first electric push rod 403 is fixedly connected to one side of the sliding seat 404. The controller 405 is electrically connected to the reducer 406. Mounting holes are evenly arranged on the outer side of the mounting block 407. The cutter 408 and the mounting block 407 form a locking structure through the mounting holes. The slide rail 409 is symmetrically distributed at the bottom of the slide plate 410. The slide rail 409 is slidably connected to the slide plate 410. One side of the sliding seat 404 is set with an inclined surface. The output end of the second electric push rod 411 is fixedly connected to one side of the slide plate 410.
[0030] By activating the first electric push rod 403, the sliding seat 404 slides horizontally on the first guide rail 401 and the second guide rail 402. Similarly, by activating the second electric push rod 411, the sliding plate 410 slides on the slide rail 409. This facilitates the movement of the tool 408 to one side of the bearing according to its size, enabling the machining of bearings of different sizes and ensuring accurate cutting depth. By mounting the tool 408 on the mounting block 407, and then activating the controller 405 via the reducer 406 to rotate the mounting block 407, the tool feed speed reaches 40m / min, with a repeatability of 0.003mm, ensuring accurate feed speed. This allows the mounting block 407 to drive the tool 408 to precisely shape the complex curved surface of the bearing, enabling the lathe to machine high-precision dimensions and shapes required for the bearings of the humanoid robot reducer.
