[0034] The clamping fixture 21 is provided with a ejecting device 24 which can reciprocate with it. The movable part on the ejecting device 24 which moves laterally is convenient for automatically ejecting the workpiece clamped on the clamping station 201, thereby improving the discharge efficiency of the equipment, speeding up the production rate of the equipment, eliminating the complex structure of the manipulator, saving the space occupied by the manipulator, and making the interior of the equipment more compact.

The clamping fixture 21 is eccentrically fixed on the turntable 222, and the clamping station 201 is set close to the edge of the turntable 222. Through the operation of the divider 221, the clamping fixture 21 can be accurately rotated to the first position, the second position, or the third position, and the action is fast, thereby improving the processing efficiency.

[0039] Through the three-dimensional motion device 33 of the above structure, the drilling assembly 31 and the tapping assembly 32 can be flexibly moved, which is convenient for processing workpieces of different specifications or drilling and tapping at different positions of the workpiece. The drilling assembly 31 and the tapping assembly 32 are driven and fed by two independent groups of front and rear motion components 333, so that the drilling assembly 31 and the tapping assembly 32 can move back and forth and then work in turns, thereby avoiding the workpiece and reducing interference with each other.

[0041] The driving assembly includes a driving motor, a coupling, a screw shaft and a screw nut. The output end of the driving motor is connected to one end of the coupling, the screw shaft is connected to the other end of the coupling, the screw nut is sleeved on the screw shaft, the screw nut of the left and right movement assembly 331 is connected to the fixed frame of the up and down movement assembly 332, the screw nut of the up and down movement assembly 332 is connected to the fixed frame of the front and back movement assembly 333, the drilling assembly 31 and the tapping assembly 3 are fixed on the screw nuts of the front and back movement assembly 333 (the driving assembly belongs to the prior art and will not be explained or marked here).

[0042] The slide rail assembly includes a second fixed slide rail and a second movable slider, the second fixed slide rail is fixedly arranged on each fixed frame, and the second movable slider is arranged on the fixed frame of the adjacent motion assembly, and the left and right motion assemblies 331, the up and down motion assemblies 332 and the two groups of front and rear motion assemblies 333 achieve mutual sliding cooperation through the second fixed slide rail and the second movable slider (the slide rail assembly belongs to the prior art and will not be explained or marked here).

[0043] The drilling assembly 31 and the tapping assembly 32 both include an axle box 341, and the two axle boxes 341 are arranged side by side up and down. An output spindle 342 is fixedly connected to each axle box 341, and the two output spindles 342 are respectively connected to a drilling head 343 and a tapping head 344, and the drilling head 343 is arranged directly above the tapping head 344;.

[0044] Or in other embodiments, the drilling head 343 is disposed directly below the tapping head 344 .

[0045] The machine platform is also provided with an automatic conveyor belt 4, which is arranged beside the clamping fixture 21 in the third position; after the workpiece is processed and pushed away from the clamping station 201 by the ejection device 24, the automatic conveyor belt 4 can hold the workpiece and quickly transport the workpiece to the discharge end.

[0046] The turntable motion device 23 includes a first fixed slide rail 231, a first movable slide rail 232 and a driving cylinder 233. The first fixed slide rail 231 and the driving cylinder 233 are fixed on the machine platform 1. The first movable slide rail 232 is fixed to the bottom surface of the indexer 221 and is slidably connected to the first fixed slide rail 231. The telescopic shaft 234 of the driving cylinder 233 is connected to the indexer 221. Through the above structure, the workpiece can be moved from the loading position to the processing position.

[0047] In combination with the above structure, the working principle of the profile double-end surface drilling and tapping mechanism is as follows:

[0048] The turntable motion device 23 drives the indexer 221 to slide to the loading position. During this process, the indexer 221 rotates the clamping clamp 21 to make the clamping station 201 in the first position. After the equipment puts the workpiece into the clamping station 201, the clamping cylinder 213 works to make the pressure plate 24 move downward and clamp the workpiece. At this time, the clamped workpiece is in the first position of the clamping clamp 21.

[0049] Processing the first situation: when only the double end faces (A face and B face marked in the figure) of the workpiece are processed, the turntable motion device 23 drives the indexer 221 to slide directly toward the drilling and tapping module 3 to the processing position, and the three-dimensional motion device 33 of the drilling and tapping module 3 works to drive the drilling assembly 31 and the tapping assembly 32 to perform drilling and tapping processing on the A face of the workpiece in sequence. After the processing of the A face is completed, the indexer 221 rotates the clamping fixture 180°, and the clamping fixture 21 drives the clamped workpiece to rotate to the third position. Thereafter, the drilling and tapping module 3 moves from the first position to the third position following the workpiece, and performs drilling / tapping processing on the B face of the workpiece on the side of the A face;

[0050] Processing the second situation: when only the outer side surface (surface C marked in the figure) of the workpiece is processed, the indexer 221 rotates the clamping fixture 90°, and the clamping fixture 21 drives the clamped workpiece to rotate to the second position. At the same time, the turntable motion device 23 drives the indexer 221 to slide toward the drilling and tapping module 3 to the processing position, and the three-dimensional motion device 33 of the drilling and tapping module 3 works to drive the drilling assembly 31 and the tapping assembly 32 to drill and tap the outer side surface of the workpiece in turn. Then the indexer 221 rotates the clamping fixture 90° again, and the clamping fixture 21 drives the clamped workpiece to rotate to the third position.

[0051] The third processing situation: when the workpiece is processed on both end faces and a single side face, the difference is that the drilling assembly 31 and the tapping assembly 32 perform drilling and tapping processing on the A side of the workpiece in turn, and after the A side is processed, the indexer 221 rotates the clamping fixture 90°, and the clamping fixture 21 drives the clamped workpiece to rotate to the second position, and the drilling assembly 31 and the tapping assembly 32 perform drilling and tapping processing on the outer side of the workpiece in turn, and after the outer side is processed, the indexer 221 rotates the clamping fixture 90° again, and the clamping fixture 21 drives the clamped workpiece to rotate to the third position, and the drilling assembly 31 and the tapping assembly 32 perform drilling / tapping processing on the B side of the workpiece on the A side in turn.

[0052] Drilling / tapping is performed on the B surface on the side of the A surface; after the B surface or the outer surface of the workpiece is processed, the clamping cylinder 213 drives the pressing plate 214 to release the workpiece, and then the ejecting cylinder 241 works, driving the ejecting shaft 242 to quickly extend into the clamping station 201 and push the workpiece, so that the workpiece leaves the clamping station 201 and slides into the automatic conveyor belt 4, and then the workpiece is sent out of the equipment.
