It is understood that the rotating arm motor 221 and clamping head motor 241 of workpiece fixed mechanism 200 can respectively by
Controller carries out intelligent control.The rotation of workpiece fixed mechanism 200 is driven using two motors, wherein 241 band of clamping head motor
Start building part pitch angle (perpendicular to the axial direction of workpiece) variation, rotating arm motor 221 control workpiece level angle (be parallel to workpiece
It is axial).Since the adjustment axis (the second rotary shaft 231) of workpiece pitch angle is installed on level angle adjustment axis (the first rotary shaft
211) on, therefore when carrying out level angle adjustment axis (the first rotary shaft 211) variation, the adjustment axis (second of pitch angle
Rotary shaft 231) as coupled relation changes, one reversed angular adjustment is exported to pitch axis by controller at this time
Instruction can offset two axis because of the brought pitch axis angle change of coupled relation.
Shown in Figure 5, grinding apparatus further includes multiple feed mechanisms 600, and feed mechanism 600 and grinding workpieces clamping fill
It sets and is arranged in a one-to-one correspondence.Feed mechanism 600 includes stock shelf 601 and feeding driving assembly 602, and stock shelf 601 passes through feeding
Frame mounting plate 603 is mounted in mounting base 500, and stock shelf 601 is used to temporarily fix to grinder part or ground finished piece(s).Feeding drives
Dynamic component 602 can be cylinder, and cylinder realizes the feeding of workpiece by back and forth movement and pushes back movement, and then send workpiece accurately
Up in the clamping head 230 of workpiece fixed mechanism 200, the folder of workpiece is realized in the gripper cylinder movement convenient for cooperating on clamping head 230
It holds.Meanwhile the cylinder of feed mechanism 600 can be retracted in time again, avoid and interfere between stock shelf 601 and rotating arm 210.
It is understood that feed mechanism 600 is fixed on the top of rotation arm assembly namely mounting base 500, pass through cylinder
It drives, work piece holder 604 is installed on the stock shelf 601 of feed mechanism 600, work piece holder 604 is processed according to workpiece configurations
It forms, workpiece, which is placed on work piece holder 604, can be kept fixed position.After the cylinder of feed mechanism 600 stretches out, workpiece is sent to rotation
230 position of clamping head of 210 end of pivoted arm, after gripper cylinder controls the clamping workpiece of clamping head 230, the rotation of rotating arm 210 makes work
Part leaves work piece holder 604, and work piece holder 604 then return back to waiting charging position under the drive of cylinder, completes feeding process.
When discharging, finished piece(s) can will have been ground by feed mechanism 600 and has been driven far from the movement of clamping head 230 in place, so that completion will have been ground
Part is disassembled from clamping head 230, naturally, the workpiece ground can also be directly dynamic by the gripper cylinder of clamping head 230
It falls in rack 800, realizes discharging.
Referring to shown in Fig. 8,11 or 13, multiple fast pulleys are also arranged at intervals on the abrasive belt mechanism of the present embodiment grinding apparatus
105, setting is spaced between multiple fast pulleys 105.It is understood that tensioning wheel 104 can also play the role of fast pulley, but
