Description

Technical Field

[0001] This utility model relates to the field of gearbox turbine housings, and more specifically, it relates to a device for machining threaded holes in gearbox turbine housings. Background Technology

[0002] As the core component of the reducer, the turbine housing needs to be bolted to the housing shell, bearing end cover, input and output shafts and other parts through threaded holes to form a complete transmission cavity. The accuracy of the threaded holes directly affects the coaxiality and sealing of the assembly of each component, preventing lubricating oil leakage or foreign matter intrusion. Therefore, in the manufacturing process of the reducer turbine housing, threaded hole machining is one of the key processes, and its machining accuracy and efficiency directly affect the assembly quality and production cycle of the turbine housing.

[0003] Currently, turbine box thread hole machining equipment requires manual tool changing, which is cumbersome and time-consuming, resulting in low machining efficiency. This problem is particularly prominent in small-batch, multi-specification production scenarios. In addition, manual tool changing is prone to positioning deviations, affecting the machining accuracy of thread holes. Furthermore, frequent operations increase the labor intensity of workers. Although some automated equipment can achieve tool changing, it relies on complex tool changing arm structures, resulting in high equipment costs and difficult maintenance.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a device for machining threaded holes in a gearbox turbine housing. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for machining threaded holes in a gearbox turbine housing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gearbox turbine housing thread hole processing device, comprising a clamping mechanism for fixing the gearbox turbine housing, wherein a processing mechanism for processing the thread hole of the gearbox turbine housing fixed on the clamping mechanism is mounted on the back of the clamping mechanism; The machining mechanism includes a worktable and a robotic arm mounted on the worktable. A machining spindle is mounted on the robotic arm, and a threading tool is detachably connected to the machining spindle via an electric quick-release assembly. A tool placement table is also mounted on the worktable, through which various threading tools are placed for replacement of the machining spindle.

[0007] Preferably, the electric quick-release assembly connects the machining spindle and the thread cutting tool by magnetic attraction.

[0008] Preferably, the electric quick-release assembly includes a circular groove seat mounted on the drive end of the machining spindle, and a circular block fixed to the head of the threading tool and capable of being inserted into the circular groove seat. An electromagnetic chuck is installed on the inner top wall of the circular groove seat, and a steel block is installed on the top of the circular block.

[0009] Preferably, the clamping mechanism includes a fixed platform, with vertical plates fixedly connected to both sides of the top of the fixed platform, and electric telescopic rods installed on opposite surfaces of the vertical plates, with clamping plates fixedly connected to the transmission parts of the electric telescopic rods.

[0010] Preferably, a limiting groove for placing the reducer turbine housing is provided at the middle of the top of the fixed platform.

[0011] Preferably, an electric turntable is installed at the bottom of the robotic arm, and the tool placement platform is located on the back of the robotic arm.

[0012] Preferably, both the worktable and the fixed platform are made of cast iron.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves rapid tool replacement and precise positioning through the coordinated work of the multi-axis motion of the robotic arm and the electric quick-release component, avoiding the tediousness and errors of manual operation, significantly improving processing efficiency and accuracy. At the same time, the structure is simple, reducing equipment complexity and maintenance costs, thus solving the problems in the background technology. 2. In this utility model, both the workbench and the fixed platform are made of cast iron. Cast iron has a high density and is heavier than ordinary materials for the same volume, which can stably support the device. 3. In this utility model, the tool placement table is set on the back of the robotic arm. The back of the robotic arm is usually a non-primary working area. Placing the tool placement table here can avoid it occupying the space in front of or to the side of the machining spindle, reducing the overall footprint of the equipment and making the worktable layout more compact. This is especially suitable for production workshops with limited space. On the other hand, the electric turntable can drive the robotic arm to rotate flexibly. When changing tools, the robotic arm only needs to rotate a specific angle to quickly align the machining spindle with the tool placement table. There is no need for complex lateral or longitudinal movements, which shortens the tool changing path and improves the tool changing efficiency. Attached Figure Description

[0016] like Figure 1-5 As shown, this utility model provides a gearbox turbine box thread hole processing device, including a clamping mechanism 1 for fixing the gearbox turbine box, and a processing mechanism 2 for processing the thread hole of the gearbox turbine box fixed on the clamping mechanism 1 is installed on the back of the clamping mechanism 1. The machining mechanism 2 includes a worktable 201 and a robotic arm 202 mounted on the worktable 201. A machining spindle 203 is mounted on the robotic arm 202, and a thread cutting tool 205 is detachably connected to the machining spindle 203 via an electric quick-release assembly 204. A tool placement table 206 is also mounted on the worktable 201, through which various thread cutting tools 205 are placed for replacement of the machining spindle 203.

[0017] This invention first uses a clamping mechanism 1 to fix the turbine housing, ensuring stable positioning during processing. When threaded hole processing is required, the robotic arm 202 mounted on the worktable 201 operates according to a preset program. Its movable end, the machining spindle 203, automatically connects the required threading tool 205 from the tool placement table 206 with the assistance of the electric quick-release assembly 204. The robotic arm 202 moves the machining spindle 203 to the turbine housing's processing position, and the machining spindle 203 drives the threading tool 205 to rotate and be fed by the robotic arm 202, completing the threaded hole processing. If the threading tool 205 needs to be replaced, the robotic arm 202 returns the current threading tool 205 to the tool placement table 206, reconnects the new tool, and repeats the above processing steps. The entire process, through the multi-axis motion of the robotic arm 202 and the coordinated work of the electric quick-release assembly 204, achieves rapid tool replacement and precise positioning, avoiding the tediousness and errors of manual operation, significantly improving processing efficiency and accuracy. Simultaneously, the simple structure reduces equipment complexity and maintenance costs.

[0018] The electric quick-release assembly 204 connects the machining spindle 203 and the thread cutting tool 205 by magnetic attraction. The electric quick-release assembly 204 includes a circular groove seat 2041 installed on the transmission end of the machining spindle 203, and a circular block 2042 fixed to the head of the thread cutting tool 205 and able to be inserted into the circular groove seat 2041. An electromagnetic chuck 2043 is installed on the inner top wall of the circular groove seat 2041, and a steel block 2044 is installed on the top of the circular block 2042.

[0019] In use, the turbine housing is first fixed by the clamping mechanism 1 to ensure stable positioning during machining. When a threaded hole needs to be machined, the robotic arm 202 operates according to a preset program, driving the machining spindle 203 to move above the tool placement table 206, aligning the circular groove seat 2041 with the circular block 2042 of the corresponding thread machining tool 205. At this time, the electromagnetic chuck 2043 is energized to generate a magnetic field, attracting the steel block 2044 at the top of the circular block 2042, inserting the circular block 2042 of the tool head into the circular groove seat 2041 to complete the magnetic connection. The robotic arm 202 then drives the machining spindle 203 to move to the turbine housing's machining position, and the machining spindle 203 drives... The cutting tool rotates, and at the same time, the robotic arm 202 controls the machining spindle 203 to feed axially to achieve thread cutting. When changing tools, the robotic arm 202 moves the thread cutting tool 205 back to the tool placement table 206, the electromagnetic chuck 2043 is de-energized and demagnetized, and the magnetic connection is released. Then the above process is repeated to connect the new tool. The whole process uses the power on and off control of the electromagnetic chuck 2043 to achieve quick tool disassembly and assembly (quick replacement). Combined with the multi-axis motion of the robotic arm 202 for precise positioning (precise positioning of machining position and tool change position), it avoids the tediousness and error of manual tool changing, and simplifies the tool changing components through the magnetic structure, reducing equipment complexity and maintenance costs.

[0020] The clamping mechanism 1 includes a fixed platform 101. Vertical plates 102 are fixedly connected to both sides of the top of the fixed platform 101, and electric telescopic rods 103 are installed on the opposite surfaces of the vertical plates 102. The transmission parts of the electric telescopic rods 103 are fixedly connected to clamping plates 104. The fixed platform 101 serves as a basic support component, providing a stable placement plane for the turbine box. When it is necessary to fix the turbine box, the electric telescopic rods 103 on both sides of the vertical plates 102 are started synchronously. The extension amount of the telescopic rods is controlled by the electronic control system, which drives the clamping plates 104 to move towards the turbine box. As the clamping plates 104 contact the two sides of the turbine box, the electric telescopic rods 103 continuously apply thrust until the clamping plates 104 on both sides tightly clamp the turbine box in the middle, thereby fixing the turbine box.

[0021] Furthermore, firstly, both the worktable 201 and the fixed table 101 are made of cast iron. Cast iron has a high density and is heavier than ordinary materials for the same volume, providing stable support for the device. Secondly, the fixed table 101 has a limiting groove 1011 at the top center for placing the reducer turbine housing. The shape of the limiting groove 1011 matches the bottom contour of the turbine housing (e.g., a rectangular groove is suitable for a square housing). This physical limiting allows for quick determination of the workpiece's reference position, avoiding orientational deviations when manually placed on the fixed table 101, which would affect the subsequent thread hole machining effect. Finally, the bottom of the robotic arm 202 is equipped with an electric turntable 3, and a cutting tool... The tool placement table 206 is located on the back of the robotic arm 202. The back of the robotic arm 202 is usually a non-primary working area. Placing the tool placement table 206 here avoids it occupying the space in front of or to the side of the machining spindle 203, reducing the overall footprint of the equipment and making the layout of the worktable 201 more compact, which is especially suitable for production workshops with limited space. On the other hand, the electric turntable 3 can drive the robotic arm 202 to rotate flexibly. When changing tools, the robotic arm 202 only needs to rotate a specific angle (180°) to quickly align the machining spindle 203 with the tool placement table 206 without complicated lateral or longitudinal movements, shortening the tool changing path and improving tool changing efficiency.
