Description

Technical Field

[0001] This invention relates to the field of steel bar milling, specifically a steel bar surface milling apparatus. Background Technology

[0002] In the field of machining, surface milling of steel bars is a common and critical process, and its processing quality directly affects the performance and lifespan of the steel bars in subsequent use. Traditional steel bar surface milling equipment has many shortcomings in the feeding, milling, and recycling stages.

[0003] Regarding feeding, many devices rely on manual placement of steel bars, which is not only inefficient but also prone to affecting product quality in subsequent processing. During the feeding process, the feeding mechanism of some devices cannot stably and accurately push the steel bars, resulting in uneven milling and reduced surface finish. Traditional devices have fixed milling cutter positions and angles, allowing only unidirectional milling of the steel bar surface. For steel bars with complex shapes or high surface quality requirements, this is insufficient, easily leading to dead corners or substandard surface roughness. Finished steel bars often pile up haphazardly, hindering subsequent sorting and handling and potentially causing surface damage due to collisions and compression. As the machining industry's demands for production efficiency, product quality, and automation continue to increase, traditional steel bar surface milling devices are no longer adequate for modern production needs. Therefore, a new steel bar surface milling device needs to be designed to solve this problem. Summary of the Invention

A power component is installed in the power box, and a power shaft is installed at the output end of the power component. The end of the power shaft away from the power component passes through the top wall of the power box.

[0007] As a further embodiment of the present invention: the pushing assembly includes a dial, which is fixedly mounted on a power shaft. A lever is eccentrically mounted on the dial. A rotating shaft is rotatably mounted on the base. A conveying disc is fixedly connected to the end of the rotating shaft away from the base. A grooved wheel is fixedly mounted on the rotating shaft.

A guide plate is fixedly mounted on the end of the connecting frame away from the push block, and the connecting frame passes through the limiting groove. A guide groove is formed on the guide plate. A guide rod is eccentrically mounted on the conveying disc. The end of the guide rod away from the conveying disc extends into the guide groove, and the guide rod slides against the inner wall of the guide groove.

[0008] As a further embodiment of the present invention: the milling assembly includes a rotating groove, the inner wall of the mounting groove is provided with a rotating groove, a rotating block is slidably disposed in the rotating groove, a gear ring is fixedly installed on one side of the rotating block, the mounting plate is fixedly connected to the side of the gear ring away from the rotating block, a drive shaft is rotatably mounted on the vertical plate, one end of the drive shaft is connected to a connecting unit, the other end of the drive shaft is mounted with a drive gear, the drive gear meshes with the gear ring, and the end of the connecting unit away from the drive shaft is connected to a power shaft.

[0009] As a further embodiment of the present invention: the feeding and recycling assembly includes a driven shaft, one end of which extends into the receiving hopper and is fixedly connected to the side wall of the receiving cylinder; a driven bevel gear is mounted on the other end of the driven shaft; the driven shaft is rotatably connected to the side wall of the receiving hopper; a rotating rod is rotatably mounted on the base; a half-bevel gear is mounted on the end of the rotating rod away from the base; the half-bevel gear intermittently meshes with the driven bevel gear; a connecting mechanism is mounted on the power shaft; the end of the connecting mechanism away from the power shaft is connected to the rotating rod; an intermittent mechanism is mounted on the driven shaft; the end of the intermittent mechanism away from the driven shaft is connected to the feeding block.

[0010] Compared with the prior art, the beneficial effects of this invention are as follows: Through the ingenious design of the feeding bin, conveying chamber, feeding block, and feeding trough, combined with the power transmission of the feeding and recovery assembly, the steel bar can automatically fall into the feeding trough under gravity and achieve automatic feeding as the feeding block rotates, reducing the tedious operation of manual feeding, saving labor costs, and improving feeding efficiency; under the drive of the power assembly, the material assembly converts the continuous rotation of the power shaft into the intermittent reciprocating linear motion of the push block, enabling the push block to push the steel bar stably and accurately according to the set rhythm, ensuring the stability of the steel bar's posture during milling, and gradually moving towards the milling cutter side, providing a reliable motion basis for subsequent milling processing, and avoiding manual feeding. The instability and error of the feeding process improve the continuity and efficiency of the processing. The feeding and recovery assembly drives the receiving cylinder to rotate intermittently. The rotation of the receiving cylinder is used to orderly transport the processed steel bars to the recovery port, realizing the centralized recovery of the steel bars. This facilitates subsequent handling or processing in the next process, further improving the automation and efficiency of the entire processing flow. The milling assembly, through a series of transmission structures, enables the milling cutter to move circumferentially around the steel bar in the milling cavity, and to mill the surface of the steel bar from multiple angles. This avoids the uneven milling problem caused by processing in a single direction, effectively improving the processing quality of the steel bar surface, making the steel bar surface flatter and smoother, and meeting higher processing accuracy requirements.

[0022] 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.

[0023] Please see Figures 1 to 11As an embodiment of the present invention, a steel bar surface milling device includes a base 1, on which a vertical plate 2 is fixedly installed. A milling table 3 is fixedly installed on one side of the vertical plate 2. The milling table 3 has a feeding bin 4, a conveying cavity 5, and a milling cavity 6. The bottom of the feeding bin 4 is connected to the conveying cavity 5, and the bottom wall of the conveying cavity 5 is connected to the milling cavity 6. A feeding block 30 is rotatably arranged in the conveying cavity 5, and a plurality of feeding grooves 31 are opened on the feeding block 30. A push block 7 is arranged in the milling cavity 6, and the push block 7 slides with the inner wall of the milling cavity 6. A receiving platform 25 is fixedly installed on the base 1. A receiving bin 43 is opened in the receiving platform 25, and a recovery port 26 is opened at the bottom of the receiving bin 43. A receiving cylinder 28 is connected to the rotating part of the milling cavity 6. The receiving cylinder 28 is located on one side of the milling cavity 6. An installation groove 9 is provided on the vertical plate 2. A through hole 10 is provided on the installation groove 9 and communicates with the milling cavity 6. An installation plate 14 is provided on one side of the installation groove 9. A telescopic component 15 is fixedly installed at the bottom of the installation plate 14. A milling cutter 16 is fixedly installed at the end of the telescopic component 15 away from the installation plate 14. A power assembly is installed on the base 1. A pushing assembly, a milling assembly, and a feeding and recovery assembly are connected to the power assembly. The end of the pushing assembly away from the power assembly is connected to the pushing block 7. The end of the milling assembly away from the power assembly is connected to the installation plate 14. The end of the feeding and recovery assembly away from the power assembly is connected to the receiving cylinder 28 and the feeding block 30, respectively.

[0024] In this embodiment, when performing surface milling on the steel bar, the steel bar to be processed is first placed in the feed bin 4 of the milling table 3. Since the bottom of the feed bin 4 is connected to the conveying chamber 5, the steel bar enters the conveying chamber 5 under its own gravity and falls into the feed trough 31 provided on the feed block 30. After the power assembly is started, the power assembly serves as the power source for the entire machine, transmitting power to the pushing assembly, the milling assembly, and the feed recovery assembly. Driven by the power assembly, the feed recovery assembly drives the feed block 30 to rotate within the conveying chamber 5, causing the feed trough 31 to periodically rotate to the position where the bottom of the conveying chamber 5 connects with the milling chamber 6. When the feed trough 31 carrying the steel bar rotates to this position, the steel bar falls from the feed trough 31 into the milling chamber 6 under gravity, realizing automatic feeding of the steel bar. Simultaneously, the power assembly transmits power to the pusher assembly, which drives the pusher block 7 to slide linearly in the horizontal direction within the milling cavity 6. The pusher block 7 slides against the inner wall of the milling cavity 6, providing stable pushing and positioning for the steel strip entering the milling cavity 6 during its movement. This gradually pushes the steel strip into the processing area of ​​the milling cutter 16 and maintains the stability of the steel strip's posture during the milling process. The power assembly also drives the milling assembly, which in turn causes the mounting plate 14 to rotate relative to the vertical plate 2. Since the milling cutter 16 is fixedly mounted on the telescopic member 15 at the bottom of the mounting plate 14, the milling cutter 16 can perform milling processing on the surface of the steel strip under the drive of the milling assembly. The telescopic component 15 can adjust the height or position of the milling cutter 16 in real time according to the specifications of the steel strip and processing requirements, so that the milling cutter 16 maintains a suitable contact state with the surface of the steel strip, thereby achieving stable and continuous milling of the steel strip surface, improving processing accuracy and surface quality. After milling is completed, the pusher block 7 continuously pushes the steel strip to move in the discharge direction of the milling cavity 6, so that the processed steel strip enters the receiving bin 43. The feeding and recycling component transmits power to the receiving cylinder 28, driving the receiving cylinder 28 to rotate in the receiving bin 43. The rotation of the receiving cylinder 28 is used to orderly transport the processed steel strip to the recycling port 26, realizing the centralized recycling of the steel strip, which is convenient for subsequent handling or processing in the next process.

[0025] Furthermore, the telescopic component 15 can be an electric telescopic rod or an electric push rod, etc., which will not be described in detail here.

[0026] Please see Figures 1-3 As an embodiment of the present invention, the power assembly includes a power box 44, which is mounted on the base 1. A power component is installed in the power box 44, and a power shaft is installed at the output end of the power component. The end of the power shaft away from the power component passes through the top wall of the power box 44.

[0027] In this embodiment, after the power component (not shown in the figure, installed in the power box 44) is started, its output end drives the power shaft to rotate. The power shaft, as the core of power transmission of the entire device, transmits power to the pushing component, the milling component and the feeding and recycling component respectively, so that each component works according to the set motion law.

[0028] Furthermore, the power component can be a stepper motor or a servo motor, etc., which will not be described in detail here.

[0029] Please see Figures 1-10 As an embodiment of the present invention, the pushing assembly includes a dial 32, which is fixedly mounted on a power shaft. A lever is eccentrically mounted on the dial 32. A rotating shaft 33 is rotatably mounted on the base 1. A conveying disc 37 is fixedly connected to the end of the rotating shaft 33 away from the base 1. A grooved wheel 34 is fixedly mounted on the rotating shaft 33. A plurality of radial grooves 35 matching the lever are opened on the grooved wheel 34. A limiting groove 8 is opened on the bottom wall of the milling cavity 6. A connecting frame 36 is installed at the bottom of the push block 7. A guide plate 38 is fixedly mounted on the end of the connecting frame 36 away from the push block 7, and the connecting frame 36 passes through the limiting groove 8. A guide groove 40 is opened on the guide plate 38. A guide rod 39 is eccentrically mounted on the conveying disc 37. The end of the guide rod 39 away from the conveying disc 37 extends into the guide groove 40, and the guide rod 39 slides against the inner wall of the guide groove 40.

[0030] In this embodiment, during device operation, the power component drives the power shaft to rotate, and the rotation of the power shaft causes the dial 32 fixedly mounted on it to rotate synchronously. Since the lever is eccentrically mounted on the dial 32, it moves periodically along a circumferential trajectory during the rotation of the dial 32. When the lever moves to the radial groove 35 of the grooved wheel 34, the lever inserts into the radial groove 35 and exerts a pulling action on the grooved wheel 34, causing the grooved wheel 34 to rotate intermittently by a predetermined angle. The grooved wheel 34 is fixedly mounted on the rotating shaft 33; therefore, the intermittent rotation of the grooved wheel 34 causes the rotating shaft 33 to rotate intermittently synchronously, thereby driving the conveyor disc 37, which is fixedly connected to the rotating shaft 33, to produce a corresponding intermittent rotational motion. During the rotation of the conveyor disc 37, the guide rod 39, eccentrically mounted on the conveyor disc 37, moves circumferentially with the conveyor disc 37. Since one end of the guide rod 39 extends into the guide groove 40 on the guide plate 38, and the guide rod 39 slides against the inner wall of the guide groove 40, the circular motion of the guide rod 39 is converted into the reciprocating linear motion of the guide plate 38 under the constraint of the guide groove 40. The guide plate 38 is fixedly connected to the push block 7 via a connecting frame 36, and the connecting frame 36 passes through the limiting groove 8 set on the bottom wall of the milling cavity 6. Under the guidance and limiting action of the limiting groove 8, the connecting frame 36 is only allowed to move in a predetermined direction, thereby ensuring that the reciprocating linear motion of the guide plate 38 can be stably and reliably transmitted to the push block 7. With the cooperation of the above mechanism, the continuous rotation of the power shaft is converted into the intermittent reciprocating linear motion of the push block 7 in the milling cavity 6, so that the push block 7 can push the steel bar located in the milling cavity 6 gradually towards the side of the milling tool according to the set rhythm, thereby realizing the stable feeding and precise pushing of the steel bar in the milling process, providing a reliable motion basis for subsequent milling processing.

[0031] Furthermore, during the intermittent pushing of the steel bar 42 by the pusher block 7, the length pushed each time is no greater than the transverse milling range of the milling cutter 16.

[0032] Please see Figures 1-10 As an embodiment of the present invention, the milling assembly includes a rotating groove 11. The rotating groove 11 is provided on the inner wall of the mounting groove 9. A rotating block 12 is slidably disposed in the rotating groove 11. A gear ring 13 is fixedly installed on one side of the rotating block 12. The mounting plate 14 is fixedly connected to the side of the gear ring 13 away from the rotating block 12. A drive shaft 18 is rotatably mounted on the vertical plate 2. One end of the drive shaft 18 is connected to a connecting unit 41. A drive gear 17 is installed on the other end of the drive shaft 18. The drive gear 17 meshes with the gear ring 13. The end of the connecting unit 41 away from the drive shaft 18 is connected to a power shaft.

[0033] In this embodiment, when the pusher 7 intermittently pushes the steel bar 42, which has fallen into the milling cavity 6, to one side of the milling cutter 16, the rotation of the power shaft is transmitted to the transmission shaft 18 through the connecting unit 41, causing the transmission shaft 18 to rotate stably around its axis. Since the drive gear 17 is fixedly mounted on the transmission shaft 18, the rotation of the transmission shaft 18 can synchronously drive the drive gear 17 to rotate. During the rotation of the drive gear 17, the gear ring 13 rotates accordingly under meshing action. The rotation of the gear ring 13 can directly drive the rotating block 12 to move circumferentially within the rotating groove 11. The rotating block 12 is guided and limited by the rotating groove 11, thereby ensuring the stability and controllability of the movement process of the rotating block 12. Since the mounting plate 14 is fixedly connected to the side of the gear ring 13 away from the rotating block 12, the rotation of the gear ring 13 will synchronously drive the mounting plate 14 to rotate. The rotation of the mounting plate 14 further drives the milling cutter fixedly mounted at its bottom to rotate, enabling the milling cutter to move circumferentially around the steel strip within the milling cavity 6. Through the above transmission relationship, the milling cutter can change the milling angle while maintaining a stable milling posture, thereby enabling multi-angle milling of different surfaces of the steel strip, avoiding the uneven milling problem caused by single-direction processing, and improving the surface processing quality of the steel strip.

[0034] Furthermore, the connecting unit 41 can be a gear set or a worm gear and worm wheel combination, which will not be described in detail here.

[0035] Please see Figures 3 to 10 As an embodiment of the present invention, the feeding and recycling assembly includes a driven shaft 29, one end of which extends into the receiving hopper 43 and is fixedly connected to the side wall of the receiving cylinder 28. A driven bevel gear 22 is mounted on the other end of the driven shaft 29. The driven shaft 29 is rotatably connected to the side wall of the receiving hopper 43. A rotating rod 20 is rotatably mounted on the base 1. A half-bevel gear 21 is mounted on the end of the rotating rod 20 away from the base 1. The half-bevel gear 21 intermittently meshes with the driven bevel gear 22. A connecting mechanism 19 is mounted on the power shaft, connecting... Mechanism 19 is connected to the rotating rod 20 at the end away from the power shaft. An intermittent mechanism is installed on the driven shaft 29. The end of the intermittent mechanism away from the driven shaft 29 is connected to the feeding block 30. The intermittent mechanism includes a sector gear 24, which is installed on the driven shaft 29. A rotating shaft 27 is rotatably installed on the receiving platform 25. One end of the rotating shaft 27 extends into the conveying chamber 5 and is fixedly connected to the feeding block 30. The other end of the rotating shaft 27 is connected to a mating gear 23. The sector gear 24 and the mating gear 23 mesh intermittently.

[0036] In this embodiment, the power shaft drives the rotating rod 20 to rotate via the connecting mechanism 19. The half-bevel gear 21 on the rotating rod 20 rotates accordingly. When the half-bevel gear 21 meshes with the driven bevel gear 22, it drives the driven bevel gear 22 to rotate. The driven bevel gear 22 drives the receiving cylinder 28 to rotate at a certain angle via the driven shaft 29. When the half-bevel gear 21 disengages from the driven bevel gear 22, the receiving cylinder 28 stops rotating, thus achieving intermittent rotation of the receiving cylinder 28. During a single meshing process of the bevel gear 22, the half bevel gear 21 can drive the driven bevel gear 22 to rotate one revolution, causing the driven shaft 29 connected to the driven bevel gear 22 to drive the receiving cylinder 28 to rotate one revolution and reset. During the rotation of the receiving cylinder 28, when the receiving cylinder 28 is rotated 180 degrees, the steel bar 42 that has entered the receiving cylinder 28 will fall off the receiving cylinder 28 and eventually fall through the recycling port 26 at the bottom of the receiving bin 43, thus facilitating the sorting and recycling of the processed steel bar 42.

[0037] During the rotation of the driven shaft 29, the sector gear 24 is driven to rotate. The sector gear 24 meshes with the mating gear 23 during this rotation. As the sector gear 24 rotates one revolution, its meshing with the mating gear 23 causes the mating gear 23 to drive the rotating shaft 27 to rotate at a certain angle. Each rotation of the rotating shaft 27 ensures that each feeding slot 31 on the feeding block 30 rotates in an orderly manner to the bottom of the feeding bin 4 for receiving material and to the upper side of the milling cavity 6 for feeding. This allows for precise control of the feeding rhythm of the steel bars 42, avoiding material accumulation or interference caused by continuous feeding.

[0038] Furthermore, each rotation of the receiving cylinder 28 is synchronized with the rotation of the feeding block 30, so that while the receiving cylinder 28 is unloading material, the feeding block 30 is also feeding material into the milling cavity 6.

[0039] Furthermore, during the process of the pusher block 7 intermittently pushing the steel strip 42 that has fallen into the milling cavity 6 toward the side of the milling cutter 16, the semi-bevel gear 21 and the driven bevel gear 22 are disengaged, thereby ensuring that the processed steel strip 42 can stably enter the receiving cylinder 28.

[0040] Furthermore, the connecting mechanism 19 can be a gear set or a pulley set, etc., preferably a pulley set, which will not be described in detail here.

[0041] The working principle of this invention is as follows: When milling the surface of the steel bar 42, the steel bar 42 to be processed is first placed in the feed bin 4. Then, the power unit is started, and its output end drives the power shaft to rotate. The rotation of the power shaft first drives the dial 32 to rotate, and the lever on the dial 32 then makes a circular motion. When the lever enters the radial groove 35 of the grooved wheel 34, it drives the grooved wheel 34 to rotate at a certain angle. The grooved wheel 34 drives the conveyor disc 37 to rotate through the rotating shaft 33. When the conveyor disc 37 rotates, the guide rod 39 on it slides in the guide groove 40 of the guide plate 38. Because the guide rod 39 is eccentrically installed, the guide plate 38 makes an intermittent reciprocating linear motion under the restriction of the limiting groove 8. The guide plate 38 drives the push block 7 to make an intermittent reciprocating linear motion in the milling cavity 6 through the connecting frame 36. At this time, the steel bar 42 stored in the feed bin 4 falls into the feeding groove 31 on the feeding block 30 under the action of gravity (the power of the feeding block 30 comes from the power transmitted by the power shaft through the feeding recovery component). As the feeding block 30 continues to rotate, the feeding trough 31 carrying the steel strip 42 rotates to the position where the bottom wall of the conveying chamber 5 connects with the milling chamber 6, and the steel strip 42 slides into the milling chamber 6. The pusher block 7 intermittently reciprocates to push the steel strip 42 to one side of the milling cutter 16, and the pushing length each time does not exceed the transverse processing range of the milling cutter 16, ensuring that the steel strip 42 is stably within the processing range; while the pusher block 7 pushes the steel strip 42, the power shaft drives the transmission shaft 18 to rotate through the connecting unit 41, and the drive gear 17 on the transmission shaft 18 rotates accordingly. Since the drive gear 17 meshes with the gear ring 13, the drive gear 17 drives the gear ring 13 to rotate, and the gear ring 13 achieves stable rotation by sliding in the rotating groove 11 through the rotating block 12, thereby driving the mounting plate 14 to rotate. The milling cutter 16, which is fixed on the telescopic member 15 at the bottom of the mounting plate 14, rotates accordingly. The telescopic member 15 can adjust the height and position of the milling cutter 16 according to actual needs, so that the milling cutter 16 can mill the steel strip 42 from multiple angles. The milling cutter maintains a stable milling posture while changing its angle, enabling multi-angle milling of different surfaces of the steel bar. This avoids uneven milling caused by processing in a single direction, improving the surface finish of the steel bar. After milling, the steel bar 42 rotates as the power shaft drives the rotating rod 20 through the connecting mechanism 19. The half-bevel gear 21 on the rotating rod 20 rotates accordingly. When the half-bevel gear 21 meshes with the driven bevel gear 22, it drives the driven bevel gear 22 to rotate. The driven bevel gear 22 then drives the receiving cylinder 28 to rotate by a certain angle through the driven shaft 29. When the half-bevel gear 21 disengages from the driven bevel gear 22, the receiving cylinder 28 stops rotating, achieving intermittent rotation. In a single engagement of the half-bevel gear 21 and the driven bevel gear 22, the half-bevel gear 21 drives the driven bevel gear 22 to rotate one revolution, causing the driven shaft 29 to rotate one revolution and reset the receiving cylinder 28.During one rotation of the receiving cylinder 28, when it rotates 180 degrees, the steel bars 42 entering the receiving cylinder 28 will fall off and eventually fall through the recovery port 26 at the bottom of the receiving bin 43 for easy sorting and placement. The rotation of the driven shaft 29 will also drive the sector gear 24 to rotate, and the sector gear 24 will mesh with the mating gear 23 during rotation. One rotation of the sector gear 24, through meshing with the mating gear 23, causes the mating gear 23 to drive the rotating shaft 27 to rotate at a certain angle. Each rotation of the rotating shaft 27 ensures that each feeding slot 31 on the feeding block 30 rotates in an orderly manner to receive material at the bottom of the feeding bin 4 and to feed material to the upper side of the milling cavity 6, precisely controlling the feeding rhythm of the steel bars 42 and avoiding feeding chaos. Furthermore, each rotation of the receiving cylinder 28 is synchronized with the rotation of the feeding block 30. When the receiving cylinder 28 discharges material, the feeding block 30 feeds material into the milling cavity 6. During the intermittent pushing of the steel strip 42 by the pusher block 7 to the side of the milling cutter 16, the half bevel gear 21 and the driven bevel gear 22 are in a disengaged state, ensuring that the steel strip 42 after milling is completed enters the receiving cylinder 28 stably, and the entire milling process is completed in an orderly and efficient manner.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
