Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 3: an automatic bar feeding and discharging device for a grinding machine comprises a support frame 2 arranged on the grinding machine 1, wherein one end of the support frame 2 is provided with a feeding box 3 which is distributed in an inclined way, the bottom of the support frame 2 is provided with a feeding cylinder 4, the working end of the feeding cylinder 4 is connected with a positioning clamping seat 5 which is connected on the support frame 2 in a sliding way, the positioning clamping seat 5 is positioned at an outlet at the bottom end of the feeding box 3), the other end of the support frame 2 is provided with a receiving box 6 which is distributed in an inclined way, the feeding box 3 and the receiving box 6 are respectively positioned at two ends of a pair of grinding rollers 7,

The utility model discloses automatic upper and lower bar device's for grinding machine working process as follows: a worker puts a bar 14 to be processed into the feeding box 3, and the feeding box 3 is integrally distributed in an inclined manner, so that the bar 14 automatically rolls downwards along the feeding box 3 under the action of self weight, and in an initial state, the positioning clamping seat 5 is positioned at an opening at the bottommost end of the feeding box 3, and thus one bar 14 is bound to fall into the positioning clamping seat 5; when the surface treatment of the bar 14 is needed, the device is started, a control system of the device firstly controls a feeding cylinder 4 to work, the feeding cylinder 4 drives a positioning clamping seat 5 and the bar 14 on the positioning clamping seat to move upwards together, and when the positioning clamping seat 5 stops moving, the bar 14 just moves to a feeding height;

the control system can also control the electric push rod 8 to drive the lifting cylinder 9 to move in the horizontal direction, at the moment, the first mechanical arm 11 and the second mechanical arm 12 move along with the lifting cylinder 9, and as the distance between the positioning clamping seat 5 and the grinding roller 7, the distance between the grinding roller 7 and the material receiving box 6 and the distance between the first mechanical arm 11 and the second mechanical arm 12 are all L, when the electric push rod 8 moves to one end of the stroke, the first mechanical arm 11 is just positioned right above the bar 14, and the second mechanical arm 12 is positioned right above the processing stations of the pair of grinding rollers 7; at the moment, the control system sends an instruction to the lifting cylinder 9, the lifting cylinder 9 drives the connecting seat 10 and the two manipulators to descend together, and after the lifting cylinder 9 acts to reach the extending limit stroke, the first manipulator 11 acts to grab the bar 14 on the positioning clamping seat 5; in the process, the second manipulator 12 is in idle gripping;

after the first mechanical arm 11 finishes acting, the lifting cylinder 9 drives the connecting seat 10 to ascend and return to an initial position, then the electric push rod 8 drives the lifting cylinder 9 to move to the other end of the stroke, at the moment, the first mechanical arm 11 is positioned right above the processing station of the grinding roller 7, the second mechanical arm 12 is positioned above the material receiving box 6, the control system controls the lifting cylinder 9 to act again to drive the two mechanical arms to descend, the first mechanical arm 11 descends and then places a bar material 14 to be processed on the processing station of the grinding roller 7, and the grinding roller 7 can polish the surface of the bar material 14 in the rotating process; in this process, the second manipulator 12 is empty;

after the first bar 14 is taken away, the feeding cylinder 4 drives the positioning clamping seat 5 to descend, after the positioning clamping seat 5 returns to the bottom opening of the feeding box 3 again, the second bar 14 falls onto the positioning clamping seat 5, then the feeding cylinder 4 drives the positioning clamping seat 5 to ascend, and the second bar 14 is conveyed to the feeding height, so that the first manipulator 11 can take materials in the next step;

the lifting cylinder 9 drives the two manipulators to ascend again, the control system controls the electric push rod 8 to move, the first manipulator 11 returns to the position right above the second bar 14, after the processing time is up, the device repeats the operation, and the first manipulator 11 grabs the second bar 14; while the first manipulator 11 acts, the second manipulator 12 also descends and grabs the first processed bar 14, then the two manipulators ascend together, the electric push rod 8 acts to enable the first manipulator 11 to move to the position above the processing station, and the second manipulator 12 moves to the position above the material receiving box 6; the first mechanical arm 11 descends, a second bar material 14 is placed on the processing station, the second mechanical arm 12 descends, the processed first bar material 14 is placed on the material receiving box 6, and the first bar material 14 can roll down to the lower end of the material receiving box 6 under the action of self gravity;

go on according to above-mentioned process repeatedly, can realize the automatic feeding of a plurality of bars 14, processing and get the material operation, can use manpower sparingly work greatly, improve work efficiency, the staff only need in time take out when the material receiving box 6 is full of bars 14, in time the replenishment when the bars 14 in last magazine 3 consume.
