Description

Technical Field

[0001] This utility model relates to the field of wheel and axle processing technology, specifically a high-precision grinding processing equipment for the traveling wheel and axle of an aircraft bomb-carrying vehicle. Background Technology

[0002] Aircraft munition loading vehicles are one of the core pieces of equipment in military airport ground support systems, used for the safe and efficient loading and transport of aviation munitions. Their axles, as key load-bearing components, must withstand heavy loads, impacts, and complex operating conditions; therefore, they have extremely high requirements for dimensional accuracy, surface roughness, geometric tolerances, and material strength. According to CN219005496U, a grinding platform for online machining of roller shafts is disclosed. This technology discloses "a grinding platform for online machining of roller shafts, relating to the field of roller shaft technology; the present invention includes a lathe, a pair of support frames fixedly mounted on the upper surface of the lathe, a placement table fixedly mounted on the upper end of the support frames, a pair of rotating wheels rotatably mounted on the placement table, a roller shaft mounted on the rotating wheels, a connecting groove opened at the end of the roller shaft, a rotating mechanism on the lathe, the rotating wheels fitting against both ends of the roller shaft, and the connecting groove located at the center of the roller shaft." This technology offers the following advantages: "The roller shaft is placed on the rotating wheels, and a connecting rod is inserted into the connecting groove on the roller shaft. The rotating mechanism drives the roller shaft to rotate along the rotating wheels. A grinding device then fits against the roller shaft to grind it, achieving the required performance. This lathe is lightweight and easy to carry and install." Significant technological limitations still exist in existing automated wheel and axle grinding equipment. Although an automated conveying system is used to load workpieces, the traditional clamping mechanism limits the equipment to processing only one wheel and axle at a time. This single-piece operation mode severely restricts production efficiency and makes it difficult to meet the needs of the aerospace manufacturing industry for mass production. Utility Model Content

Positioning component 32 is mounted on machining table 1 and used for workpiece positioning; Grinding assembly 33 is mounted on machining table 1 and used for workpiece grinding.

[0017] In this embodiment, the rotation of the shaft 313 drives the finger cylinder 314 to flip to the right to a horizontal position. The finger cylinder 314 drives the clamping plate 315 to cooperate with the clamping groove 316 to clamp a row of wheel axles in the pallet 4. Then, it flips to the left to a horizontal position, thereby placing a row of wheel axles into the positioning component 32. Through batch clamping, the workpiece is quickly transferred, significantly improving the material handling efficiency.

[0018] Specifically, the gear 317 includes a guide rail 3181 fixed to the top of the mounting base 311, a rack 3182 slidably mounted in the guide rail 3181, a first cylinder 3183 fixed to the front end of the top of the mounting base 311, and a connector 3184 fixed between the output end of the first cylinder 3183 and the right end of the rack 3182.

[0019] In this embodiment, the output end of the first cylinder 3183 drives the connector 3184 to drive the rack 3182 to slide along the guide rail 3181. The rack 3182 drives the shaft 313 to rotate through the gear 317. The left and right flipping is controlled by the extension and retraction of the output end of the first cylinder 3183.

[0020] Specifically, the positioning component 32 includes a Y-axis electric slide 321 mounted on the top of the processing table 1. A base 322 is fixed on the slider of the Y-axis electric slide 321. A positioning seat 323 is fixed on the top of the base 322. Several positioning slots 324 are opened inside the positioning seat 323. A positioning plate 325 is slidably mounted on the front end of the positioning seat 323. A second cylinder 326 is mounted on the front end of the base 322 and is used to drive the positioning plate 325 to move.

[0021] In this embodiment, after the wheel axle held by the pick-and-place component 31 is placed into the positioning groove 324 on the positioning seat 323, the positioning plate 325 is driven by the second cylinder 326 to fix the wheel axle, so as to avoid shaking and position displacement during subsequent grinding.

[0025] In this embodiment, by placing unprocessed axles in the pallet 4 and conveying the pallet 4 intermittently by the conveyor 2, the pick-and-place component 31 can pick up an entire row of axles from the pallet 4 each time.

[0026] Specifically, the contact surface of the positioning plate 325 is machined with anti-slip texture to increase friction with the wheel axle.

[0027] In this embodiment, additional anti-slip fixing force is provided when the second cylinder 326 drives the positioning plate 325 to press the wheel axle.

[0028] The working principle and usage process of this utility model are as follows: First, the unprocessed wheel axles are placed in the pallet 4 and conveyed intermittently by the conveyor 2; then, the output end of the first cylinder 3183 drives the connector 3184 to drive the rack 3182 to slide along the guide rail 3181. The rack 3182 drives the shaft 313 to rotate through the gear 317. The rotation of the shaft 313 drives the finger cylinder 314 to flip to the right to the horizontal. The finger cylinder 314 drives the clamping plate 315 to cooperate with the clamping groove 316 to clamp a whole row of wheel axles in the pallet 4. Then, it flips to the left to the horizontal, thereby placing a whole row of wheel axles into the positioning component 32. After the wheel axle held by the pick-and-place assembly 31 is placed into the positioning groove 324 on the positioning seat 323, the positioning plate 325 is driven by the second cylinder 326 to fix the wheel axle, so as to prevent the position from shifting during subsequent grinding; then the positioning assembly 32 is driven to move backward as a whole by the Y-axis electric slide 321. Finally, the grinding machine 334 is driven by the X-axis electric slide 332 and the Z-axis electric slide 333 to perform grinding on the wheel shaft.
