Description

Technical Field

[0001] This invention relates to the field of mechanical processing equipment technology, specifically to a multi-axis four-station automatic processing machine for decorative ring wheels. Background Technology

[0002] Traditionally, drilling and tapping of decorative ring wheels relies primarily on conventional machining centers. After clamping, manual positioning is required, followed by drilling and tapping one hole at a time using drills and taps. Currently, the number of decorative holes ranges from approximately 12 to 36. The more holes, the slower the process, and the short lifespan of drills and taps makes it difficult to guarantee drilling and tapping quality. Manual cleaning is also required after drilling, but the quality of this cleaning is inconsistent, potentially hindering subsequent installation. Therefore, a multi-axis, four-station automated machining center for decorative ring wheels needs to be designed to simultaneously drill and tap multiple holes, significantly improving production efficiency while automatically completing the cleaning process.

[0029] The working principle of this invention is as follows: When the automatic loading and unloading door 12 is opened, the wheel is placed on the sliding plate 21. The pneumatic clamping block 22 and the axial positioning block 25 are fixed to different positions on the sliding plate 21 by bolts to accommodate wheels of different sizes. The clamping cylinder drives the clamping block 29 to descend, and the wheel is clamped by the clamping block 29. The radial positioning block 23, the axial positioning block 25, and the circumferential positioning block 24 achieve accurate positioning of the product, while ensuring that the wheel will not rotate or deviate. The automatic loading and unloading door 12 is then closed.

[0030] After the wheel is positioned, the indexing motor 72 drives the indexing screw to rotate, and the indexing screw drives the movable base 26 to slide on the slide rail 71, so that the positioning clamping mechanism moves to the bottom of the drilling mechanism. Then, the drilling spindle motor 36 drives the drilling screw to rotate, and the drilling screw drives the drilling slider to descend, and the drilling mechanism moves downward. At the same time, the drilling guide column 34 and guide column 28 ensure the accuracy of the movement, and the drilling template 31 ensures the stability of the drill bit. The drill bit 32 drills the wheel, and the operation is completed after drilling to the specified depth. The drilling mechanism is then lifted as a whole.

[0031] After drilling is completed, the indexing motor 72 drives the positioning and clamping mechanism to move to the cleaning mechanism. The cylinder 43 drives the nozzle plate 42 to descend, and the nozzles 41 on the nozzle plate 42 start blowing air to clean the drilled holes. After a fixed cleaning time, the cylinder 43 drives the nozzle plate 42 to lift up, completing the cleaning work.

[0032] After the cleaning operation is completed, the indexing mechanism drives the positioning and clamping mechanism to the tapping mechanism. Then, the tapping spindle motor 53 drives the tapping screw to rotate, the tapping screw drives the tapping slide to descend, and the tapping slide drives the tapping spindle 54 and the tapping multi-spindle device 52 to descend. At the same time, the tapping guide post 51 and the guide post 28 ensure the accuracy of the movement. The tap 55 taps the wheel. After tapping to the specified depth, the tapping operation is completed. The tapping mechanism is then lifted as a whole to complete the tapping operation.

[0033] After the tapping operation is completed, the indexing mechanism drives the positioning and clamping mechanism to the cleaning mechanism. The cylinder 43 drives the air nozzle plate 42 to move downward, and the air nozzle 41 starts to blow air to clean the tapped hole. After cleaning, the cylinder 43 drives the air nozzle plate 42 to lift up, completing the post-tapping cleaning operation.

[0034] After the cleaning operation is completed, the indexing mechanism drives the positioning and clamping mechanism to move to the initial position, the automatic loading and unloading door 12 opens, and the wheels are taken out.
