Description

Technical Field

[0001] This application relates to the field of gear processing, and in particular to a processing equipment and method for a main reduction gear wheel. Background Art

[0002] In industrial manufacturing, between automation and precision control devices, a speed reducer (or power transmission device) is usually used to reduce and transmit the high-load rotational speed transmitted by the drive shaft of a power source (such as an electric motor, a servo motor, etc.). In the production of speed reducers, multiple sets of reduction gear wheels with different specifications are required.

[0003] When the existing reduction gear wheels are processed, they need to go through multiple processing procedures such as milling and grinding. Usually, it is necessary for workers to install them on a processing machine tool. After one processing procedure of the reduction gear wheel is completed, it is disassembled and then installed on another processing machine tool for processing until all the procedures of the reduction gear wheel are completed.

[0004] Regarding the above related technologies, the inventor found the following defects: By workers installing the reduction gear wheel on a processing machine tool for processing, during the processing, the reduction gear wheel rotates at a high speed. When the installation of the reduction gear wheel is unstable, it is easy to fall off, thus causing potential safety hazards. Summary of the Invention

[0005] In order to improve the stability of the reduction gear wheel during processing, this application provides a processing equipment and method for a main reduction gear wheel.

[0006] A processing equipment for a main reduction gear wheel provided by this application adopts the following technical scheme:

[0007] A processing equipment for a main reduction gear wheel includes a processing machine tool. A plurality of processing bases for processing the reduction gear wheel are arranged on the processing machine tool. The equipment further includes a clamping mechanism and a robotic arm for driving the clamping mechanism to move. The clamping mechanism includes a rotating disk and a clamping component for clamping the reduction gear wheel. The rotating disk is rotatably arranged on the robotic arm. The clamping component is arranged on the side of the rotating disk away from the robotic arm. The robotic arm is used to drive the reduction gear wheel to be installed on the processing base.

[0008] By adopting the above technical scheme, the clamping component can clamp the reduction gear wheel. After being clamped, the reduction gear wheel can rotate synchronously with the rotating disk. The robotic arm drives the rotating disk to move so that the reduction gear wheel is installed on the processing base. The reduction gear wheel is processed on the processing base. When the reduction gear wheel rotates during processing, the turntable rotates with the reduction gear wheel to limit the reduction gear wheel, thereby improving the stability of the reduction gear wheel during processing and having better safety.

[0009] Optionally, two sets of rotating disks and clamping assemblies are provided. The rotation axes of the two sets of rotating disks are perpendicular to each other, and a position-changing assembly for exchanging the positions of the two sets of rotating disks is provided on the robotic arm.

[0010] By adopting the above technical solution, the position-changing assembly can drive the two sets of rotating disks to exchange positions. After the clamping assembly on one set of rotating disks clamps the reduction gear, the positions of the rotating disks are exchanged, so that two sets of reduction gears can be clamped and moved simultaneously. After one set of reduction gears is processed, the positions of the rotating disks are exchanged again to process the other set of reduction gears, improving the processing efficiency of the reduction gears.

[0011] Optionally, the position-changing assembly includes a rotating block and a rotating motor. The rotating block is fixedly connected to the output shaft of the rotating motor. Two mutually perpendicular mounting surfaces are provided on the rotating block, and the rotation axis of the rotating disk is perpendicular to the mounting surface.

[0012] By adopting the above technical solution, when the rotating motor drives the rotating block to rotate, the positions of the two mounting surfaces can be changed, thereby realizing the position exchange between the two sets of rotating disks. The operation is simple and convenient, and the movement is more stable. Moreover, the space occupied during the rotation of the rotating block is small, saving space.

[0013] Optionally, the clamping assembly includes a connecting cylinder, a connecting disk and clamping claws. The connecting cylinder is coaxially and fixedly connected to the side of the rotating disk away from the robotic arm. The connecting disk is coaxially and fixedly connected to the end of the connecting cylinder away from the rotating disk. At least two sets of clamping claws are provided. A chute perpendicular to the axis direction of the connecting disk is provided on the circumferential side of the connecting disk. The clamping claws are slidably adapted to the chute, and a driving member for driving multiple sets of clamping claws to approach or move away from the connecting cylinder simultaneously is provided on the connecting disk.

[0014] By adopting the above technical solution, when clamping the reduction gear, one side of the reduction gear abuts against the connecting disk, and the clamping claws abut against the circumferential side of the reduction gear, so as to realize stable clamping of the reduction gear, making the reduction gear more stable during movement and having a better processing effect.

[0015] Optionally, the driving member includes a rotating motor, a gear and a rack. The rotating motor is coaxially arranged inside the connecting cylinder. The gear is coaxially arranged on the output shaft of the rotating motor. The rack is rotatably connected to the clamping claw. The rotation axis of the rack is parallel to the axis of the connecting disk. A through hole for the rack to pass through is provided on the connecting cylinder, and the rack meshes with the gear.

[0016] By adopting the above technical solution, the rotating motor drives the gear to rotate, thereby driving the racks on multiple groups of clamping claws to move, enabling the multiple groups of clamping claws to approach or move away from each other simultaneously, achieving the clamping or detachment of the reduction gear. The use of a single power component to enable the simultaneous movement of multiple groups of clamping claws saves the manufacturing cost of the device, and at the same time, the synchronous movement of the clamping claws results in a better clamping effect on the reduction gear.

[0017] Optionally, a clamping block is provided on the side of the connection disk away from the connection cylinder, and a clamping groove adapted to the clamping block is formed on the processing base.

[0018] By adopting the above technical solution, after the reduction gear is installed on the processing base, the clamping block on the connection disk is inserted into the clamping groove on the processing base, thereby connecting the connection disk and the processing base into a whole. When the processing base drives the reduction gear to rotate, it can simultaneously drive the connection disk to rotate stably, thereby improving the processing effect of the reduction gear.

[0019] Optionally, a driving mechanism is provided on the processing machine tool. The driving mechanism includes: an X-axis driving component and a Y-axis driving component for driving the robotic arm to move in the horizontal direction; a Z-axis driving component for driving the robotic arm to move in the vertical direction.

[0020] By adopting the above technical solution, the X-axis driving component, Y-axis driving component, and Z-axis driving component cooperate to enable the robotic arm to move in space, improving the stability of the robotic arm's movement and making the robotic arm more stable during the process of transporting the reduction gear.

[0021] Optionally, multiple groups of spray heads are provided on the processing machine tool. The spray heads face the corresponding processing bases. Solenoid valves are provided on the spray heads. A water pipe is connected between the multiple groups of spray heads, and the other end of the water pipe is connected to a water source.

[0022] By adopting the above technical solution, after the reduction gear is installed on the processing base and grinding processing is carried out, the solenoid valves on the spray heads at the corresponding positions are opened, and the water in the water pipe is sprayed out from the spray heads to cool the reduction gear, enabling the reduction gear to maintain an appropriate temperature during the processing, thereby improving the processing quality of the reduction gear.

[0023] Optionally, a drainage groove is provided on the processing machine tool, and the drainage groove is arranged below multiple groups of processing bases.

[0024] By adopting the above technical solution, the waste water flushed from the reduction gear by the spray heads falls into the drainage groove, enabling centralized collection and treatment of the waste water.

[0025] A method for a processing device of a main reduction gear provided by the present application adopts the following technical solution:

[0026] A method for a processing device of a main reduction gear includes the following steps:

[0027] Step 1: The X-axis drive, Y-axis drive, and Z-axis drive cooperate to drive the robotic arm to move in space. First, move the robotic arm to the loading area to pick up the reduction gear.

[0028] Step 2: The rotating motor drives the gear to rotate, which drives the rack to move, causing multiple groups of clamping claws to approach each other to clamp the reduction gear, and installing the reduction gear on the processing base.

[0029] Step 3: The clamping block on the connecting disk is clamped with the clamping groove on the processing base. When the processing base drives the reduction gear to rotate during processing, it drives the turntable to rotate.

[0030] Step 4: When the reduction gear is being processed, the solenoid valve on the corresponding position nozzle opens to spray water on the reduction gear for cooling, and the waste water is discharged through the drainage trough.

[0031] In summary, the present application includes at least the following beneficial technical effects:

[0032] The clamping assembly can clamp the reduction gear. After clamping, the reduction gear can rotate synchronously with the rotating disk. The robotic arm drives the rotating disk to move so that the reduction gear is installed on the processing base. The reduction gear is processed on the processing base. When the reduction gear rotates during processing, the turntable rotates with the reduction gear to limit the reduction gear, thereby improving the stability of the reduction gear during processing and having better safety.

[0033] The transposition assembly can drive the two groups of rotating disks to exchange positions. After the clamping assembly on one group of rotating disks clamps the reduction gear, the positions of the rotating disks are exchanged, so that two groups of reduction gears can be clamped and moved simultaneously. After one group of reduction gears is processed, the positions of the rotating disks are exchanged again to process the other group of reduction gears, improving the processing efficiency of the reduction gears.

[0034] The rotating motor drives the gear to rotate, thereby driving the racks on multiple groups of clamping claws to move, causing multiple groups of clamping claws to approach or move away from each other simultaneously, realizing the clamping or release of the reduction gear. The simultaneous movement of multiple groups of clamping claws is achieved by one power component, saving the manufacturing cost of the device, and at the same time, the clamping claws move synchronously, resulting in a better clamping effect on the reduction gear.
