Description

Technical Field

[0001] This invention relates to the field of milling equipment technology, specifically to a milling device for aluminum cast end caps of explosion-proof motors. Background Technology

[0002] Explosion-proof motors are core power equipment in flammable and explosive environments such as petroleum and chemical industries. The aluminum cast end caps of explosion-proof motors are an important component of the motor, usually made of aluminum alloy and divided into front and rear end caps. Their core functions include fixing the rotor, stator, rectifier, and brush assembly, while also providing functions such as heat dissipation, preventing magnetic leakage, and reducing overall weight. After casting, the aluminum cast end caps need to be precision machined by milling to achieve precision control, machine the sealing structure, and enhance the functionality of the end caps. The edge of the end cap is usually equipped with multiple sets of connecting lugs to achieve the fixed assembly of the motor. Milling equipment is required when machining the lugs on the edge of the end cap.

[0003] Currently, the processing of these connecting lugs largely relies on ordinary CNC milling machines or manual drilling machines, which has the following drawbacks: 1. Low processing efficiency: Existing equipment mostly uses single-tool processing, requiring operation on each lug individually. Since the connecting lugs of aluminum cast end caps are often set in even numbers, processing time is long for end caps with multiple sets of lugs (e.g., a milling and turning processing device disclosed in patent CN114700742B, including a rotary table, milling cutter, turning tool, rotary module, compensation module, first lifting module, second lifting module, and transfer module. The rotary table drives the workpiece to rotate). 2. Poor adaptability: Explosion-proof motor end caps come in many specifications, with significant differences in diameter between different models, and significant differences in the number and spacing of lugs. Existing equipment has a long adjustment time and cannot quickly switch processing specifications. 3. Limited functionality and fragmented processes: Existing equipment is mostly dedicated to single processes; drilling requires a dedicated drilling machine, surface milling requires a dedicated milling machine, and completing the processing of one end cap requires different processes.

[0004] Therefore, there is an urgent need for a milling machine for aluminum cast end caps of explosion-proof motors that can improve processing efficiency. Summary of the Invention

This application does not specifically limit its structure in this embodiment, nor is its specific structure within the scope of protection claimed in this application. In this embodiment, a drill bit is mounted on the tool chuck 535.

[0122] Working principle: The aluminum cast end cap of the explosion-proof motor that needs to be drilled for the connecting lug is clamped and fixed by the pneumatic clamp 240. When the connecting lug is being drilled, the telescopic end of the pneumatic cylinder 230 extends into the shaft seat 210 to lock the reinforced rotating shaft 220.

[0123] The extension length of the swing arm structure of the adjustable milling tool holder 500 is adjusted according to the diameter of the aluminum cast end cap. For example, if the diameter of the aluminum cast end cap is greater than the distance between the two sets of milling parts 530, and the drill bit installed on the tool holder 535 cannot be aligned with the connecting lug on the edge of the aluminum cast end cap, the telescopic end of the pneumatic telescopic rod 513b retracts, pulling the push-pull connecting end 512c of the first swing arm 512, causing the first swing arm 512 to rotate counterclockwise. This causes the connecting sleeve end 512b of the first swing arm 512 to move away from the central mounting part 511a. When the first swing arm 512 rotates counterclockwise, it drives the second swing arms 522 at both ends to rotate as well. When the drill bit installed on the tool holder 535 can be aligned with the connecting lug on the edge of the aluminum cast end cap, the telescopic end of the pneumatic telescopic rod 513b stops retracting, completing the adjustment.

[0124] After adjustment, turn on the drive motor 533, which will drive the drill bit installed on the tool holder 535 to rotate. The extension end of the pneumatic cylinder 330 will extend and push the lead screw slider 320, causing the rotating adjustment table 400 installed on the lead screw slider 320 to move closer to the pneumatic chuck 240, so that the drill bit can perform drilling operations on the connecting lug block at the edge of the aluminum cast end cap.

[0125] After drilling the connecting lugs on the aluminum cast end cap of the explosion-proof motor, simply drive the connecting shaft 430 to rotate via the second drive motor 420, so that the adjustable milling cutter holder 500 rotates accordingly. Align the drill bits of the two sets of milling parts 530 with the connecting lugs of the other set, and then repeat the drilling steps of the previous set to complete the drilling operation of the connecting lugs on the aluminum cast end cap of the explosion-proof motor, thus shortening the processing time.

[0126] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0127] In this embodiment, a milling cutter is mounted on the tool holder 535.

[0128] When surface machining is performed on the aluminum cast end cap of the explosion-proof motor, the cutting tool on the tool holder 535 of a set of milling parts 530 is replaced with a milling cutter, and the push-pull connection end 512c of the swing arm 512 is pulled by the retraction end of the pneumatic telescopic rod 513b, causing the swing arm 512 to rotate counterclockwise, thereby moving the connecting sleeve end 512b of the swing arm 512 away from the central mounting part 511a, and extending the milling part 530 with the milling cutter installed outward; the other set of milling parts 530, through the extension end of the pneumatic telescopic rod 513b, pushes the push-pull connection end 512c of the swing arm 512, causing the swing arm 512 to rotate clockwise, thereby moving the connecting sleeve end 512b of the swing arm 512 closer to the central mounting part 511a, and pulling the milling part 530 of this set back inward.

[0129] The position of the rotary adjustment table 400 is adjusted by the lead screw slider 320 so that the cutting tool axis of the milling workpiece 530 with the milling cutter is aligned with the axis of the aluminum cast end cap of the explosion-proof motor. During the machining operation, the telescopic end of the pneumatic cylinder 230 extends into the bearing seat 210 to lock the reinforcing shaft 220. The drive motor 533 of the milling workpiece 530 is started, and then the telescopic end of the pneumatic cylinder 330 extends to push the lead screw slider 320, so that the rotary adjustment table 400 mounted on the lead screw slider 320 moves towards the end of the pneumatic clamp 240, so that the milling cutter can perform machining operation on the surface of the aluminum cast end cap. The radial position of the milling cutter is adjusted by the pneumatic push-pull component 513 driving the swing arm 512, which, together with the lateral movement of the lead screw slider 320, realizes the milling feed of the milling cutter from the axis of the aluminum cast end cap to the edge.

[0130] Example 3: This is the third embodiment of the present invention, which is based on the previous two embodiments.

[0131] In this embodiment, a turning tool is mounted on the tool holder 535.

[0132] When machining the aluminum cast end cap of the explosion-proof motor, the cutting tool on the tool holder 535 of a set of milling parts 530 is replaced with a turning tool. The telescopic end of the pneumatic telescopic rod 513b is retracted, which pulls the push-pull connection end 512c of the first swing arm 512, causing the first swing arm 512 to rotate counterclockwise. This causes the connecting sleeve end 512b of the first swing arm 512 to move away from the central mounting part 511a, extending the milling part 530 with the turning tool outward. The other set of milling parts 530 is pushed by the telescopic end of the pneumatic telescopic rod 513b, which pushes the push-pull connection end 512c of the first swing arm 512, causing the first swing arm 512 to rotate clockwise. This causes the connecting sleeve end 512b of the first swing arm 512 to move closer to the central mounting part 511a, pulling the milling part 530 of this set back inward.

[0133] The position of the rotary adjustment table 400 is adjusted by the lead screw slider 320 so that the tool axis of the milling workpiece 530, on which the turning tool is mounted, is aligned with the axis of the aluminum cast end cap of the explosion-proof motor. During machining, the drive motor 533 of the milling workpiece 530 is not started. Instead, the drive motor 250 is started to rotate the pneumatic clamp 240, causing the aluminum cast end cap mounted on the pneumatic clamp 240 to rotate. Then, the telescopic end of the pneumatic cylinder 330 extends and pushes the lead screw slider 320, causing the rotary adjustment table 400 mounted on the lead screw slider 320 to move closer to the pneumatic clamp 240, allowing the turning tool to perform turning operations on the aluminum cast end cap.
