The X-axis supporting plate is provided with a material supporting and conveying mechanism, one end of the material supporting and conveying mechanism is close to the oblique feeding mechanism, and the other end of the material supporting and conveying mechanism of the numerical control lathe body is provided with a discharging mechanism. And the numerical control lathe body is also provided with a material pushing mechanism for pushing the product to be processed out of the discharge end of the feeding channel.

When feeding, the workpieces are transversely arranged in the feeding channel, the X-axis supporting plate moves to enable the material supporting frame of the material supporting and conveying mechanism to be opposite to the material pushing mechanism, then the workpieces located at the discharging end of the feeding channel are ejected by the material pushing mechanism and enter the fixing groove of the material supporting frame, the X-axis supporting plate drives the material supporting and conveying mechanism to move to enable the workpieces to be opposite to the rotating main shaft mechanism, the movable ejector pin of the tail frame jacking mechanism extends out to push the workpieces into the elastic chuck of the rotating main shaft mechanism, and the elastic chuck clamps the workpieces to finish feeding. When the processed workpiece is a polygonal bar stock, for example, a hexagonal bar stock, that is, a hexagonal prism bar stock, and an octagonal bar stock, that is, an octagonal bar stock, the collet chuck is often provided with a structure matched with the polygonal bar stock in shape and structure in order to clamp the workpiece stably, so that the collet chuck and the workpiece need to be circumferentially positioned during feeding.

In the feeding device, because the feeding channel is not provided with a structure for circumferentially positioning the workpieces, when the workpieces are stacked and arranged in the feeding channel, the side surface of the polygonal bar stock can be attached to the bottom surface of the feeding channel, and the edge of the polygonal bar stock can be attached to the bottom surface of the feeding channel. Although the workpieces have a downward sliding process, the circumferential angles of the workpieces cannot be kept consistent when the workpieces reach the discharge end of the feeding channel due to interference between the workpieces and adjacent workpieces. Therefore, after the material pushing mechanism pushes the workpiece out of the material discharging end of the material feeding channel and enters the material supporting frame of the material supporting and conveying mechanism, the circumferential angle of the workpiece is uncertain, and the circumferential angle of the elastic chuck is fixed, so that the workpiece cannot be pushed into the elastic chuck to complete automatic feeding.

For ease of description, the polygonal bar work piece is illustrated as a hexagonal bar. Before the machining is started, piston rods of the first air cylinder 7a and the second air cylinder 7b extend, and the horizontal pushing piece 12 drives the positioning piece 10 to move into a position between the feeding slide rail 8 and the baffle plate 9a, so that the positioning plate 10a is opposite to the positioning side plate 8 a. Then the hexagonal bar can be manually laid in the storage slideway 6, at the moment, the hexagonal bar in the storage slideway 6 is in a state with uncertain circumferential angle, the side surface of the hexagonal bar can be attached to the bottom surface of the storage slideway 6, and the edge of the hexagonal bar can be attached to the bottom surface of the storage slideway 6. When machining is started, the piston rod of the second air cylinder 7b retracts, the first hexagonal bar slides down and abuts against the piston rod of the first air cylinder 7a, then the piston rod of the second air cylinder 7b extends out, the first hexagonal bar and the second hexagonal bar are separated, then the piston rod of the first air cylinder 7a retracts, the first hexagonal bar slides out of the lower slideway 6a and enters the feeding slideway 8, and then the piston rod of the first air cylinder 7a extends out. The first hexagonal bar stock slides out of the feeding slide way 8 and enters the positioning groove 10b of the positioning piece 10, then the positioning piece 10 is pushed to the notch 13b of the positioning cylinder 13 by the horizontal pushing piece 12, the notch of the positioning groove 10b is opposite to the notch 13c of the positioning hole 13a, and the first hexagonal bar stock falls into the positioning hole 13a from the positioning groove 10 b.

After the first hexagonal bar stock is fed, the machine tool processes the first hexagonal bar stock, and in the process of processing, the second hexagonal bar stock is conveyed into the positioning piece 10 to wait for being pushed out. After the first hexagonal bar is processed, the swing cylinder 22 rotates to enable the receiving hopper 18 to swing to the position of the main shaft clamp 5, the first hexagonal bar fixed on the main shaft clamp 5 is located at the opening of the receiving hopper 18, the main shaft clamp 5 releases the first hexagonal bar, the first hexagonal bar falls into the receiving hopper 18, and then the sealing plate 23 moves to close the opening of the receiving hopper 18.

After the first hexagonal bar falls into the receiving hopper 18, the receiving cylinder 15 moves and is in butt joint with the positioning cylinder 13, and the feeding operation of the second hexagonal bar is continuously completed. Thus, the working process of automatic feeding and discharging is circularly and continuously carried out.

After separating hexagonal bar and adjacent hexagonal bar through dividing material subassembly 7 and separating, this hexagonal bar continues to follow glide slope 6a gliding, at the in-process of gliding, because this hexagonal bar does not receive the interference of other hexagonal bars, in order to keep balance, the side of hexagonal bar can paste and lean on the bottom surface at glide slope 6a, forms a location. When the hexagonal bar slides out of the storage slideway 6 and falls into the feeding slideway 8, the hexagonal bar rotates around the position abutting against the bottom surface of the storage slideway 6 under the action of gravity torque by utilizing the structural characteristics of the hexagonal bar, so that two opposite side surfaces of the hexagonal bar gradually tend to be vertical. The feeding end of the feeding slide rail 8 is transversely arranged at the discharging opening of the storage slide rail 6, and positioning side plates 8a are arranged on two sides of the feeding slide rail 8, so that hexagonal bars are longitudinally placed when entering the feeding slide rail 8, the side faces of two vertical states on the hexagonal bars are respectively opposite to the two positioning side plates 8a on the feeding slide rail 8, circumferential positioning is formed when the hexagonal bars fall on the feeding slide rail 8, and the hexagonal bars are kept to slide in the circumferential positioning state in the feeding slide rail 8. Therefore, the feeding device is arranged on the machine tool, and no matter what circumferential angle the hexagonal bar is in the storage slide way 6, automatic circumferential positioning can be achieved after the hexagonal bar slides out of the storage slide way 6 and enters the feeding slide way 8.

On the positioning piece 10, because the two positioning plates 10a can be respectively opposite to the discharge ends of the two positioning side plates 8a at the same time, when the hexagonal bar slides out of the feeding slideway 8 and enters the positioning groove 10b, the positioning plates 10a and the positioning side plates 8a generate the same positioning action, so that the workpiece 1 is moved to the positioning piece 10 from the feeding slideway 8 in the same circumferential positioning state; in the process that the positioning piece 10 drives the hexagonal bar to move and the process that the hexagonal bar is separated from the positioning piece 10, the two positioning plates 10a of the positioning piece 10 have a circumferential positioning effect on the hexagonal bar all the time, so that the hexagonal bar is prevented from rotating in the moving process, and the workpiece 1 is always kept in the same circumferential positioning state for feeding. The feeding device of the machine tool can position and feed polygonal bars such as hexagonal bars and the like, so that automatic feeding of the polygonal bars can be realized. The positioning piece 10, the positioning barrel 13 and the material receiving barrel 15 are arranged, so that the hexagonal bar can continuously keep a circumferential positioning state in the feeding process after automatic circumferential positioning, and the hexagonal bar can be automatically fed after automatic positioning.
