Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see the appendix Figure 1-12 This application provides the following technical solutions.

[0019] Example 1 A feeding mechanism for a servo feeding device includes a feeding platform 1. Two baffles are vertically and symmetrically arranged on both sides of the upper end of the feeding platform 1. Several support plates 2 are vertically and symmetrically arranged between the two baffles on the upper end of the feeding platform 1. A feeding groove is inclinedly opened on one side of the upper end of each support plate 2. A constraint guide plate 4 is provided at the upper end of the feeding groove. A push-and-place box 5 is horizontally arranged on one side of each support plate 2. A first limiting block is inclinedly arranged on the side of the feeding groove near the push-and-place box 5. A feeding adaptation area 3 is sandwiched between the first limiting block and the constraint guide plate 4. A flip-top connecting shaft 6 is horizontally and rotatably arranged on the lower end of the side of the support plate 2 away from the constraint guide plate 4. A first fixed sleeve is fixedly sleeved on the side of shaft 6 near the support plate 2. The upper and lower ends of the first fixed sleeve are respectively provided with a pressing rod 7 and a first pushing rod 8. The pressing rod 7 has an arc-shaped structure. The upper ends of several pressing rods 7 are horizontally provided with a protective cover plate 9. The protective cover plate 9 is horizontally covered on the upper end of the push placement box 5. The lower end of the first pushing rod 8 is horizontally moved over the bottom of the push placement box 5. The metal rod is stored in the feeding groove. Under the action of the inclined structure, when there is one less rod at the bottom, the rod at the top automatically moves down. The constraint guide plate 4 can limit the misalignment of the rods and maintain single-layer placement. The up and down adjustment can adapt to metal rods of different diameters. A feeding assembly is set up to lift and push the metal rods in the feeding groove into the placement box 5. The feeding assembly includes a feeding connecting shaft 10 and several feeding push plates 15. The feeding push plates 15 are respectively inclined and slidably disposed on one side of several supporting uprights 2 located in the feeding adaptation area 3. The feeding push plates 15 are perpendicular to the feeding groove of the supporting uprights 2. A lifting pin 16 is horizontally provided on one side of the lower end of the feeding push plate 15. A second fixing sleeve is provided on the side of the feeding connecting shaft 10 near the lifting pin 16. A first keyway is provided on one side of the second fixing sleeve. The first keyway of the second fixing sleeve is movably sleeved with the lifting pin 16 of the feeding push plate 15. The feeding connecting shaft... A second push rod 11 is horizontally fixedly sleeved on the side of the second fixed sleeve. The push placement box 5 and the second push rod 11 are staggered. The feeding platform 1 is horizontally movable with a feeding control plate 13 on the side of the first push rod 8. The upper end surface of the feeding control plate 13 on the side of the first push rod 8 is inclined. The first push rod 8 and the second push rod 11 are both provided with a rotating wheel sleeve 12 on the side corresponding to the feeding control plate 13. When the feeding control plate 13 moves horizontally, it first contacts the rotating wheel sleeve 12 of the first push rod 8, and then contacts the rotating wheel sleeve 12 of the second push rod 11. In addition, the flip-top connecting shaft 6 and the feeding connecting shaft 10 are both provided with arc-shaped downward pressure springs on one side of the support plate 2. In the natural state, the upper end of the feeding push plate 15 is lower than the lower end of the feeding groove of the support plate 2, and the protective cover plate 9 covers the upper end of the push placement box 5.

[0020] In this embodiment, when the unloading control plate 13 moves horizontally, the unloading control plate 13 first contacts the self-rotating wheel sleeve 12 of the first push rod 8 through the inclined surface, pushing the first push rod 8 to control the flip cover connecting shaft 6 to rotate. At this time, the flip cover connecting shaft 6 controls several pressing rods 7 to flip, so that the protective cover plate 9 moves away from the push placement box 5. Then the unloading control plate 13 moves further. When the unloading control plate 13 contacts the self-rotating wheel sleeve 12 of the second push rod 11 through the inclined surface, the second push rod 11 drives the unloading connecting shaft 10 to rotate. Then the unloading connecting shaft 10 pulls the unloading push plate 15 to rise through the unloading swing arm 14. At this time, the unloading push plate 15 is slidably connected through the guide groove. The unloading push plate 15 will not rotate due to the rotation of the unloading swing arm 14, but will only be lifted. Then several unloading push plates 15 simultaneously lift up the metal rods in the unloading adaptation area 3 and slide them into the push placement box 5, waiting to be sent to the machine tool for processing.

[0021] Example 2 Based on Embodiment 1, an adjustment component is provided to adjust the width of the material feeding adaptation area 3. The adjustment component includes an adjustment connecting shaft 18 and several adjustment movable plates 17. The several adjustment movable plates 17 are slidably disposed on one side of several support uprights 2. A second limiting block is provided on one side of the adjustment movable plate 17, and the second limiting block is correspondingly disposed with the first limiting block. A second keyway is provided on the side of the adjustment movable plate 17 near the adjustment connecting shaft 18. A third fixing sleeve is provided on the side of the adjustment connecting shaft 18 near the adjustment movable plate 17. A pulling pin is provided on one side of the third fixing sleeve, and the pulling pin is movably inserted into the second keyway of the adjustment movable plate 17. When the adjustment connecting shaft 18 rotates, the adjustment connecting shaft 18 pulls the adjustment movable plate 17 to slide through the adjustment swing arm 19 and the second keyway. When the second limiting block of the adjustment movable plate 17 is misaligned with the first limiting block of the support upright 2, the width of the material feeding adaptation area 3 changes and can be adjusted according to the diameter of the metal rod.

[0022] Example 3 Based on Embodiment 2, an adaptive control component is set to adaptively control the feeding coupling 10. The adaptive control component is movably mounted on one side of the baffle. The adaptive control component includes a traction adjustment block 20, an internal threaded sleeve 22, and a swing sleeve 23. One side of the adjusting coupling 18 movably passes through the baffle. The traction adjustment block 20 is fixedly sleeved on the side of the adjusting coupling 18 that passes through the baffle. The lower end of the internal threaded sleeve 22 is movably connected to the traction adjustment block 20. The swing sleeve 23 is movably mounted on one side of the baffle via a rotation shaft. The lower end of the internal threaded sleeve 22 is provided with a connecting lug 21, which is movably connected to one side of the traction adjustment block 20 via a pin. A rotating block 24 is rotatably mounted inside the swing sleeve 23. A control rod 35 is vertically installed at the center of the lower end of the swing sleeve 23. Several assembly slots are symmetrically opened on the outer periphery of the lower end of the control rod 35. Each assembly slot is equipped with a combined threaded block 38 by bolts. The lower end of the control rod 35 is threaded into the upper end of the internal threaded sleeve 22 through several combined threaded blocks 38. When the rotating block 24 rotates, the rotating block 24 controls the insertion length of the control rod 35 and the internal threaded sleeve 22. Since the swing sleeve 23 can only rotate, when the length of the lower end of the control rod 35 inserted into the internal threaded sleeve 22 changes, the connecting ear 21 pulls and drives the adjusting block 20 to rotate the feeding shaft 10, which can realize the synchronous adjustment control of multiple adjusting movable plates 17. The upper end of the swing sleeve 23, which is fitted onto the rotating block 24, is symmetrically provided with several actuating grooves 25. The rotating block 24 is provided with a horizontal telescopic groove 26 on the side near the actuating groove 25. A piston groove 29 is provided inside the rotating block 24 on the side near the telescopic groove 26. An oil storage chamber is provided inside the rotating block 24. The piston groove 29 is connected to the oil storage chamber. A spring rod is horizontally and movably inserted between the telescopic groove 26 and the piston groove 29. A push block 27 and a pressure piston 30 are respectively provided on the side of the spring rod located inside the telescopic groove 26 and the piston groove 29. One side of the push block 27 extends out of the telescopic groove 26 and is inserted into the actuating groove 25. Both sides of the actuating groove 25 and both sides of the push block 27 are inclined surfaces. A reciprocating spring 28 is fitted on the side of the spring rod located inside the telescopic groove 26. When the rotating block 24 rotates, the push block 27 controls the pressure piston 30 to reciprocate. A wrench groove 31 is provided at the center of the upper end of the rotating block 24. A release rod 32 is inserted into the oil storage cavity through a sealing ring at the center of the wrench groove 31. A guide frame is horizontally provided at the upper end of the oil storage cavity of the rotating block 24. The lower end of the release rod 32 is movably inserted into the center of the guide frame. Several constraint rods are horizontally and symmetrically provided above the guide frame in the oil storage cavity. A reset spring 34 is sleeved between the constraint rods and the guide frame. A retaining rod 33 is vertically provided at the upper end of one constraint rod. A sealing guide groove is provided through the lower end of one side of the piston groove 29. The upper end of the retaining rod 33 is movably inserted through the sealing guide groove. A retaining groove is provided at the lower end of one side of the pressurizing piston 30. The upper end of the retaining rod 33 is movably inserted into the retaining groove through the sealing guide groove. When the release rod 32 is pressed down, the retaining rod 33 disengages from the retaining groove but does not leave the sealing guide groove, thus preventing the release rod 32 from rotating out of position and preventing air from overflowing from the oil storage cavity. The control lever 35 has a diversion groove 36 in the oil storage chamber connected to the rotating block 24. The upper end of the diversion groove 36 is connected to several assembly grooves and has several drip grooves 37. A one-way valve is provided on the side of the diversion groove 36 connected to the oil storage chamber. The detachable connection of several combined threaded blocks 38 can reduce thread damage after long-term use without replacing the swing sleeve 23 and the rotating block 24. The maintenance cost is low and the operation is simple and convenient.

[0023] In this embodiment: when the hexagonal wrench is inserted into the wrench slot 31, the hexagonal wrench pushes the release lever 32 to compress the reset spring 34, and the retaining lever 33 disengages from the retaining slot of the pressure piston 30. At this time, the rotating block 24 rotates, and the pushing block 27, under the elastic force of the reciprocating spring 28 and the action of the inclined surfaces on both sides, reciprocates into several actuating slots 25. Then, the pressure piston 30 reciprocates in the piston slot 29. At this time, the rotating block 24 rotates one revolution, and the pressure piston 30 reciprocates multiple times, continuously pressurizing the air inside the rotating block 24, thus pressurizing the air inside the rotating block 24. The lubricating oil passes through the one-way valve and is sent into the diversion groove 36. Then, under the dripping action of the oil dripping groove 37, it drips into the assembly groove of the control rod 35 to lubricate several combined threaded blocks 38. After use, the hexagonal wrench is removed, the release rod 32 is raised, and if the retaining rod 33 is slightly misaligned with the retaining groove, the self-rotating block 24 is gently twisted to make the pushing block 27 stably inserted into the actuating groove 25. Under the action of the return spring 34, the retaining rod 33 is automatically inserted into the retaining groove to limit the rotation of the self-rotating block 24 and improve the stability of the feeding coupling 10 after adjustment. In addition, the one-way valve is a small, low-pressure liquid one-way valve commonly used in the prior art. This one-way valve can be replaced with a one-way dripping diaphragm. When the pressurizing piston 30 does not increase the pressure on the oil storage chamber of the rotating block 24, the lubricating oil is in a static and leak-free state. When the rotating block 24 rotates, it can lubricate the connecting threads of the combined threaded block 38 and the internal threaded sleeve 22, thereby improving the service life of the device.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
