[0029] A buffer 41 is provided at the end of the Z-axis platform 24 to match the side of the motor bracket 25 .

[0030] The working process of the automatic end face milling device of the embodiment of the present invention is as follows: first, a plurality of workpieces to be subjected to end face milling are placed in the vibrating loader 39, and the vibrating loader 39 is started. Under the action of the vibrating loader 39, the plurality of workpieces enter the feeding chute 40 one by one until the first workpiece enters the feeding position at the end of the feeding chute 40.

[0031] When the device is working, the turntable motor 8 in the feeding turntable mechanism 1 works, driving the turntable 9 to perform a step-by-step rotation action (i.e., it rotates a fixed angle at a certain time interval), so as to drive the workpiece on its receiving ring 13 to move between multiple workstations in sequence; during the movement, the status indication shaft 10 will be linked with the turntable 9, that is, there is a certain corresponding relationship between the rotation states of the two, and each time the turntable 9 rotates one circle, the status indication sensor 12 will be triggered once by the cam 11, that is, the status indication sensor 12 can determine the current working state of the turntable 9 by detecting the cam 11; so that the control system of the device can monitor the working state of the device;

[0032] When the loading mechanism 2 is working, the Z-axis loading cylinder 14 drives the loading plate 17 downward, allowing the suction nozzle 18 at one end of the loading plate 17 to contact the workpiece on the feeding position, and then the control system will control the air circuit control system to operate, the suction nozzle 18 adsorbs the workpiece, and then the Z-axis loading cylinder 14 drives the loading plate 17 upward. After the movement is in place, the loading motor 16 works to drive the loading plate 17 to rotate 180°, and then the Z-axis loading cylinder 14 drives the loading plate 17 downward. At this time, the workpiece is placed in the receiving ring 13 at the loading station on the turntable 9, and the air circuit control system disconnects the air circuit of the current suction nozzle 18, and the workpiece falls into the corresponding receiving ring 13, completing a loading operation;

[0033] The feeding mechanism 2 operates repeatedly according to the above process to achieve continuous feeding operation;

[0034] After the loading mechanism 2 completes a complete loading action, the turntable 9 stops after rotating a certain angle, and the workpiece is transported to the milling station. After the turntable 9 finishes the action, the control system controls the clamping cylinder 21 to work, driving the clamping head 22 downward, and the clamping head 22 presses on the top of the workpiece to provide a counter-force for the workpiece during the processing; the control system also controls the Z-axis lifting cylinder 42 to work, pushing the Z-axis platform 24 to a predetermined height, and then the X-axis cylinder 28 works to drive the motor bracket 25 to move along the X-axis direction. During this process, the milling motor 26 drives the milling cutter 27 to rotate at a high speed. Since the bottom end of the workpiece (the end being processed) interferes with the horizontal motion trajectory of the milling cutter 27, when the motor bracket 25 moves, the milling cutter 27 will mill the bottom end of the workpiece;

[0035] After the milling mechanism 3 finishes working, the turntable 9 rotates again. When the workpiece after milling processing is transported to the material picking mechanism 4, the turntable 9 stops moving, and the control system controls the pneumatic clamping mechanism 30 to operate. The upper clamping jaw 31 and the lower clamping jaw 32 in the pneumatic clamping mechanism 30 move toward each other, and the two respectively contact the upper end surface and the lower end surface of the material receiving ring 13 located at the material picking station. At this time, the first feeding channel 33 and the second feeding channel 34 are connected to each other, and the air path control system blows high-pressure gas in the direction of the first feeding channel 33 through the second feeding channel 34. Under the action of air pressure, the workpiece enters the material receiving box 35 along the first feeding channel 33 and falls into the workpiece container 36 through the opening at the bottom of the material receiving box 35; a material receiving box 35 is provided at the end of the first feeding channel 33, which can allow the workpiece to first contact the baffle or the inner wall of the material receiving box 35 provided in the material receiving box 35, thereby reducing the falling speed of the workpiece and preventing the workpiece from falling quickly into the workpiece container 36 and causing damage;

[0036] After the material taking operation is completed, the turntable 9 rotates again at a certain angle and then stops. The sensor 38 detects whether there is a workpiece in the material receiving ring 13 at the detection station below it. If there is a workpiece, the control system will control the sound and light warning mechanism connected to it to work, reminding the staff to deal with it in time. If there is no workpiece, the device works normally.

[0037] The turntable 9 rotates again, and the idle receiving ring 13 returns to the loading station, waiting for the loading mechanism to perform the next loading operation.
