The traditional method is to use an ordinary drilling machine to drill, chamfer, and tap one by one. The disadvantage is that the operation is complicated and the work efficiency is too low. Utility Model Content
[0003] This invention addresses the problem of low work efficiency when using ordinary drilling machines to process mounting holes for electric vehicle wheel hubs by providing a six-station drilling, chamfering, and tapping machine.
[0004] The technical solution of this utility model is a special machine for processing wheel hub mounting holes of two-wheeled electric vehicles. Its special feature is that a hydraulic dividing table is installed in the middle of the flat worktable, and a flat disc-shaped turntable is installed on the hydraulic dividing table. Six sets of three-star positioning blocks are evenly distributed on the outer periphery of the turntable, and circumferential positioning columns are installed on the outer side of the positioning blocks.
[0005] A drilling machine frame is mounted on the rear left side of the turntable on the workbench. A drilling head protrudes inward from the top of the drilling machine frame. A drilling multi-spindle is mounted below the drilling head. Two vertical drilling guide pillars are mounted on the outer edge of the drilling multi-spindle. The lower ends of the drilling guide pillars are fixed to the workbench. A horizontal guide plate is mounted below the drilling multi-spindle. The guide plate is slidably connected to the drilling guide pillars. Two spring shafts are mounted between the guide plate and the inside of the drilling multi-spindle. A center positioning block is mounted below the guide plate. Guide holes corresponding to the number of holes required for the hub are opened around the center positioning block.
[0006] The front left side of the turntable on the workbench is equipped with an upper chamfering frame, the upper part of which is equipped with a chamfering head that protrudes inward, and the lower part of the chamfering head is equipped with a chamfering multi-spindle.

The upper part of the drilling cylinder frame is bent backward into a longitudinal direction. The front end of the upper part of the drilling cylinder frame is equipped with a vertical drilling cylinder. The lower end of the drilling cylinder is equipped with a horizontal drilling air blowing plate. The drilling air blowing plate has vertical through holes corresponding to the number of holes required for the hub.

[0010] During operation, first, install the drill bits, chamfering tools, and taps corresponding to the required number of holes in the hub under the drilling multi-spindle, chamfering multi-spindle, and tapping multi-spindle respectively. Place the center hole of one hub onto the outer periphery of the first positioning block on the turntable, ensuring the hub's valve hole is aligned with the circumferential positioning post. Start the hydraulic dividing table, causing the turntable, positioning blocks, and hub to rotate clockwise. Stop when the first positioning block with the hub is inside the drilling frame. The drilling head starts and moves downwards, pushing the drilling multi-spindle and guide plate downwards via the drilling guide post and spring shaft, so that the guide plate rests against the hub. The center positioning block of the guide plate enters the center hole of the hub, and the drilling head drives the drill bit on the drilling multi-spindle to drill a hole in the hub. At this point, install the hub on the second positioning block.
[0011] After drilling is completed on the hub of the first positioning block, the drilling head drives the multi-spindle and guide plate to rise and reset. The hydraulic dividing table starts, causing the turntable to continue rotating. The hub on the first positioning block rotates to the inside of the chamfering frame and stops. The chamfering head drives the chamfering device under the chamfering multi-spindle to chamfer the drilled hole on the hub. At this time, the hub is installed on the third positioning block, while the hub on the second positioning block is being drilled.
[0012] After the hub on the first positioning block is chamfered, the hydraulic dividing table starts, driving the turntable to continue rotating. The hub on the first positioning block rotates to the inside of the drilling cylinder frame and stops. The drilling cylinder starts, pushing the drilling air blower plate down close to the hub. The air source is activated, and air is supplied through the drilling air pipe and the drilling air nozzle to blow away debris from the chamfered hole. At this time, the hub is installed on the fourth positioning block, the hub on the third positioning block is being drilled, and the hub on the second positioning block is being chamfered.
[0013] After the hub on the first positioning block is drilled and chipped, the hydraulic dividing table starts, driving the turntable to continue rotating. The hub on the first positioning block rotates to the inside of the tapping machine frame and stops. The tapping head drives the tap under the multi-spindle tapping head to tap the chipped hole on the hub. At this time, the hub is installed on the fifth positioning block, the hub on the fourth positioning block is being drilled, the hub on the third positioning block is being chamfered, and the hub on the second positioning block is being blown to remove chips.
[0014] After the hub on the first positioning block is tapped, the hydraulic dividing table starts, driving the turntable to continue rotating. The hub on the first positioning block rotates to the inside of the tapping cylinder frame and stops. The tapping cylinder starts, pushing the tapping air blower plate down close to the hub. The air source is activated, and air is supplied through the tapping air guide tube and the tapping air nozzle to blow air and remove chips from the tapped hole. At this time, the hub is installed on the sixth positioning block, the hub on the fifth positioning block is being drilled, the hub on the fourth positioning block is being chamfered, the hub on the third positioning block is being blown air to remove chips, and the hub on the second positioning block is being tapped.
[0015] After the wheel hub on the first positioning block is tapped and chipped, the hydraulic dividing table starts, driving the turntable to continue rotating. The wheel hub on the first positioning block stops at the starting position, and the machined wheel hub is removed and replaced with the wheel hub to be machined. At this time, the wheel hub on the sixth positioning block is being drilled, the wheel hub on the fifth positioning block is being chamfered, the wheel hub on the fourth positioning block is being drilled and chipped, the wheel hub on the third positioning block is being tapped, and the wheel hub on the second positioning block is being tapped and chipped, and so on in a cycle.
