[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A continuous feeding device for machining mechanical parts comprises a base 1, a connecting plate 2 is arranged above the base 1, two reciprocating screws 3 are rotatably arranged between the base 1 and the connecting plate 2, an equipment slot 4 is arranged on the base 1, a power mechanism connected to one of the reciprocating screws 3 is arranged in the equipment slot 4, the two reciprocating screws 3 are connected by a rotating mechanism, a screw sleeve 10 is threadedly sleeved on the two reciprocating screws 3, and rotating rods 12 are rotatably arranged on the outer walls of both sides of the screw sleeve 10 through a torsion spring, a rotating frame 8 is installed on the two rotating rods 12, and two placement grooves are arranged on the rotating frame 8, a rack 13 is installed on the bottom wall of the connecting plate 2, and the rotating rod 12 cooperates with the rack 13 through a transmission mechanism.

[0022] The power mechanism includes a drive motor 5 arranged in the equipment slot 4. The end of the reciprocating screw 3 rotates through the upper end surface of the base 1 and extends into the equipment slot 4. The output shaft of the drive motor 5 is fixedly connected to the end of the reciprocating screw 3. The drive motor 5 is the power device in this scheme. Its arrangement on the base 1 increases the weight of the base 1, ensuring the stability of the overall device placed on the ground, and the installation height is low, which is also convenient for inspection and maintenance.

[0023] The rotating mechanism includes two transmission pulleys 6 rotatably arranged on the upper end surface of the connecting plate 2. The ends of the two reciprocating screws 3 rotate through the connecting plate 2 and are fixedly connected to the transmission pulleys 6. The two transmission pulleys 6 are connected by a connecting belt 7. With the help of the above-mentioned transmission pulleys 6 and the connecting belt 7, power transmission is achieved. When the driving motor 5 drives one of the reciprocating screws 3 to rotate, the synchronous rotation of the other reciprocating screw 3 can be achieved.

[0024] The transmission mechanism includes a gear 14 fixedly arranged on the outer wall of the rotating rod 12, and the gear 14 is meshed with the rack 13. When the gear 14 follows the screw sleeve 10 and the rotating rod 12 to rise to a certain height, it will mesh with the rack 13. In the subsequent rising process of the screw sleeve 10, due to the setting of the rack 13, the gear 14 will drive the rotating frame 8 to rotate with the help of the rotating rod 12, so as to facilitate the tilting and pouring out of the rod-shaped parts in the placement groove on the rotating frame 8.

[0025] The screw sleeves 10 on the outer walls of the two reciprocating screws 3 are initially distributed up and down, and the rotating frame 8 is initially in an inclined state. As shown in the figure, the up and down distribution allows the two rotating frames 8 to move up and down, one at a high place to unload materials, and the other at a low place to wait for materials to be put in.

[0026] A limit rod 9 is provided between the base 1 and the connecting plate 2, and a sliding sleeve 11 is fixedly provided on the outer wall of the screw sleeve 10. The sliding sleeve 11 is slidably sleeved on the limit rod 9. The above-mentioned limit rod 9 is vertically arranged and parallel to the reciprocating screw 3, which realizes the limitation of the screw sleeve 10 to prevent it from rotating with the reciprocating screw 3.

[0027] When the utility model is used, when the outer wall of the rod-shaped part needs to be polished, it needs to be polished with the help of a polishing machine. The rod-shaped part can be lifted in turn by the continuous feeding device of the present solution and finally poured into a placement platform of a polishing machine with a certain height to wait for subsequent polishing. Specifically:

[0028] Two rod-shaped parts are placed in the two placement grooves on the rotating frame 8 at the lower position. Since it is tilted backward, the rotating frame 8 can effectively avoid the occurrence of the above-mentioned rod-shaped parts slipping during the rising process. Starting the drive motor 5 will drive the reciprocating screw 3 directly connected to it to rotate. When the reciprocating screw 3 rotates, the screw sleeve 10 on its outer wall will drive the rotating frame 8 to rise with the help of the rotating rod 12. When the rotating frame 8 rises to a certain height, the gear 14 will mesh with the rack 13 and rotate during the subsequent rising process of the screw sleeve 10, so that the notch of the placement groove on the rotating frame 8 is tilted forward, so that the rod-shaped parts therein will slip and fall on the placement platform of the polishing machine to wait for being picked up for processing.

[0029] This solution is provided with two rotating frames 8. In the initial state, one is at a high position and the other is at a low position. As the reciprocating screw 3 rotates, the high position will descend and the low position will rise. The high position is in an unloading state and the low position is in a waiting state for loading, thereby ensuring the continuity and convenience of loading.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
