SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is a great deal of drawback of the general feed mechanism of current bearing ring, provides special lasso supply apparatus of bearing for this reason.
The technical scheme of the utility model is that: the utility model provides a special lasso feed arrangement of bearing, it includes the feed inlet, settle in the one-level that is used for connecing the draw work piece by the feed inlet and holds the material mechanism, settle in the second grade that the one-level held the material mechanism below and hold the material mechanism, the one-level holds the material mechanism and includes the horizontal flitch of depositing that is located the workstation to and perpendicular push pedal, wherein is fixed with the flitch on the perpendicular push pedal, but the flitch is by driving actuating cylinder drive horizontal migration, but the second grade holds the material mechanism and including settling the conveyer belt at long-pending flitch rear, settles the second grade that holds the material mechanism.
In the scheme, the feed inlet is provided with a round inverted opening.
The improvement of the scheme is that the guide rail of the secondary material storage mechanism is provided with a tablet pressing sensor linked with the driving cylinder.
In the scheme, the vertical push plate is fixed on the support frame through a bolt, and the support frame is fixedly connected to the side edge of the driving cylinder.
The beneficial effects of the utility model are that to be arranged by lathe feed inlet exhaust work piece neatly in second grade holding mechanism, after second grade holding mechanism row is full, be located the preforming sensor on the second grade holding mechanism and to driving actuating cylinder signaling, drive actuating cylinder and reply original station, push pedal stop work, bearing ring is not being pushed to the conveyer belt by the propelling movement. And when the number of the workpieces of the secondary material storage mechanism is reduced, the tabletting sensor does not send a signal any more, the driving cylinder recovers to work, the workpieces continue to be pushed, and the feeding is completed. The device can be suitable for batch collection of long and thin cylindrical workpieces, workpieces with center holes and sleeve workpieces, and has the advantages of rapid and neat feeding and low energy consumption.
FIG. 1 is a schematic view of a pre-job material string of the present invention;
FIG. 2 is a schematic view of the working state of the present invention;
in the figure, the device comprises a feed inlet 1, a feed inlet 2, a material accumulating plate 3, a driving cylinder 4, a vertical push plate 5, a material feeding plate 6, a workpiece 7, a conveying belt 8, a secondary material storage mechanism guide rail 9, a tabletting sensor 10 and a workbench.
The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments of the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, a special bearing ring supply device comprises a feed port 1, a first-stage material storage mechanism arranged beside the feed port and used for receiving and guiding a workpiece 6, and a second-stage material storage mechanism arranged below the first-stage material storage mechanism, wherein the first-stage material storage mechanism comprises a horizontal material accumulation plate 2 positioned on a workbench 10, and a vertical push plate 4, wherein a material feeding plate 5 is fixed on the vertical push plate through bolts, the material feeding plate is driven by a driving cylinder 3 to move horizontally, the second-stage material storage mechanism comprises a conveying belt 7 arranged behind the material accumulation plate, and a second-stage material storage mechanism guide rail 8 arranged below the conveying belt.
Example 1: the universal bearing ring feeding mechanism comprises a feeding hole 1, a first-stage material storage mechanism for guiding a workpiece is arranged below the feeding hole, a feeding plate 5 is fixed on a vertical pushing plate 4 through a bolt, the pushing plate is driven by a driving cylinder 3 to move horizontally, the pushing plate is fixed on the cylinder, and two steel bars are added on two side edges to increase supporting rigidity. As shown in the figure, the lowest end of the material accumulating plate 2 is located right below the upper material plate, and the material accumulating plate is mainly used for bearing a workpiece.
Example 2: as shown in fig. 2, the difference from embodiment 1 is that a feed sensor 9 linked with a drive cylinder is provided on the machine tool behind the feed mechanism. The feeding sensor is positioned above a guide rail of the secondary material storage mechanism, and when the feeding sensor senses a workpiece, the secondary material storage mechanism is full, and the driving cylinder needs to stop working continuously.
Example 3: the difference with embodiment 2 lies in that material loading sensor and driving cylinder signal connection, give driving cylinder start signal again after about 3 seconds for driving cylinder start signal when material loading sensor, drive driving cylinder drive material loading board and promote the work piece along the horizontal direction, until the work piece falls into secondary and holds the material mechanism.
