Ferrule cutting apparatus

Abstract

This invention relates to the field of bearing processing equipment technology, specifically a bearing ring cutting device. It includes a base and a right spindle box mounted on the base. This device features a dual-spindle design, with both spindles operating synchronously during cutting, effectively ensuring product parallelism and tool safety. Simultaneously, due to the synchronous operation of the dual spindles, the number of cutting tools can be reduced by 30% compared to ordinary tools, resulting in 14-15 more products per steel pipe, significantly improving enterprise benefits. Furthermore, external turning can generate additional revenue from iron filings; what previously required three to four passes on a centerless grinder can now be completed with just one pass. Additionally, ordinary cutting machines leave approximately 1mm of material at the end of each steel pipe, requiring manual cutting on another machine; this device can completely remove this material. To ensure the parallelism of the cut product at the end of the steel pipe, a "lifting mechanism" operates simultaneously when the steel pipe enters the right spindle, effectively guaranteeing product quality requirements.

Description

Technical Field

[0001] This invention relates to the field of bearing processing equipment technology, specifically bearing ring cutting equipment. Background Technology

[0002] Bearings, a key mechanical component, are widely used in various precision and heavy machinery devices. Their core components include bearing rings (inner and outer rings), rolling elements, and cages. The manufacturing of bearing rings begins with bearing steel tubes, which require a series of precise machining processes to be formed.

[0003] In the production process of bearing rings, the first step is to accurately select bearing steel tubes from the inventory area, and then transport them to a dedicated blanking machine through an efficient transportation system. On the blanking machine, the steel tubes must be cut into blanks of a specific length in strict accordance with the design requirements, which is the basis for forming bearing rings.

[0004] However, current bearing blanking equipment often faces a significant bottleneck after cutting steel pipes: it requires additional equipment for subsequent finishing processes, especially the turning of the outer diameter of the steel pipe. This process not only increases the complexity and difficulty of the production line, but also significantly reduces overall production efficiency and increases production costs.

[0005] The main reason for this is the limited functionality of existing material cutting equipment. They primarily focus on cutting operations while neglecting the connection and integration with subsequent finishing processes. In addition, insufficient compatibility between different equipment also leads to breakpoints and inefficiencies in the production process. Therefore, we propose a ring cutting device.

[0014] In some embodiments, the roller mechanism includes a movable roller rotatably connected to a material rack, a shaft rotatably connected to the material rack, a movable arm rotatably connected to the shaft rotatably, an adjustable positioning roller rotatably connected to one end of the movable arm rotatably, a movable arm rotatably connected to the shaft rotatably, an adjustable positioning roller rotatably connected to one end of the movable arm rotatably, and an adjustable mechanism provided on the material rack, wherein the adjustable mechanism, the movable arm rotatably connected to the adjustable positioning roller rotatably, and the adjustable mechanism, the movable arm rotatably connected to the adjustable positioning roller rotatably are respectively connected to the connecting rods via rotating shafts; Furthermore, the material rack is equipped with an adjustable bolt connected to the adjustable mechanism.

During the movement of the L-shaped clamp, the gear plate meshes with the rack, and the L-shaped clamp continues to move, causing the gear plate to roll along the rack, thereby causing the rectangular plate to rotate.

[0017] This invention has at least the following beneficial effects: This device features a dual-spindle design, with the left and right spindles operating synchronously during cutting, effectively ensuring the parallelism of the product and the safety of the cutting tool. Meanwhile, because it is a dual-spindle synchronous operation, the number of cutting tools can be reduced by 30% compared to ordinary cutting tools, resulting in fourteen or fifteen more products per steel pipe, which significantly improves the company's efficiency. At the same time, external turning can generate additional revenue for enterprises from iron filings. Originally, centerless grinders required three to four passes, but with this equipment, only one pass is needed. Meanwhile, ordinary cutting machines leave about 1 mm of material at the end of each steel pipe, which needs to be cut manually on another machine. This machine can cut all of it. Meanwhile, in order to ensure the parallelism of the cut product at the end of the steel pipe, when the steel pipe enters the right spindle, the "lifting mechanism" works simultaneously, which effectively guarantees the product quality requirements. Meanwhile, to facilitate product replacement, the roller mechanism on the material rack is designed with a self-returning principle, which can be easily and quickly completed with just one "adjustable bolt"; Meanwhile, since it is a fully automatic device, the steel pipes on the rack may be of different lengths or be misaligned. To solve this problem, a "pre-feeding mechanism" has been designed to deliver the steel pipes that are not in place to the designated position. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Example 1 Please see Figures 1-9 The present invention provides a technical solution: a ring cutting device, including a base 1, and further comprising: The right spindle box 2 is mounted on the base 1, and the right spindle box 2 is equipped with a cutting head mechanism 3 for cutting the material head. The cutting head operation is performed on only one side of a steel pipe. The outer diameter support plate 4 is set on the right spindle box 2 and is used to turn the outer diameter of the steel pipe. The outer diameter turning can generate additional revenue for the enterprise from iron filings. The original centerless grinder required three to four cuts, but this equipment only requires one cut. The left spindle box 5 is mounted on the base 1 and is coaxial with the right spindle box 2. The left spindle box 5 is equipped with a cutting tray 6 for cutting steel pipes. The clamping mechanism 7 is installed on the left spindle box 5 and the right spindle box 2 to clamp the steel pipe; The feeding tailstock 8 is set on one side of the base 1, and the feeding tailstock 8 is equipped with a feeding mechanism 9 for moving the steel pipe; Specifically, this device features a dual-spindle design, with the left and right spindles operating synchronously during cutting, effectively ensuring the parallelism of the product and the safety of the cutting tool. Meanwhile, because it is a dual-spindle synchronous operation, the number of cutting tools can be reduced by 30% compared to ordinary cutting tools, and each steel pipe can produce fourteen or fifteen more products, resulting in significant benefits for the enterprise. At the same time, external turning can generate additional revenue for enterprises from iron filings. Originally, centerless grinders required three to four passes, but with this equipment, only one pass is needed. Meanwhile, ordinary cutting machines leave about 120mm of material at the end of each steel pipe, which needs to be cut manually on another machine. This machine can cut all of it. Meanwhile, in order to ensure the parallelism of the cut product at the end of the steel pipe, the "lifting mechanism 29" works simultaneously when the steel pipe enters the right spindle, which effectively guarantees the product quality requirements. Meanwhile, to facilitate product replacement, the roller mechanism 39 on the material rack 31 is designed with a self-returning principle, which can be easily and quickly completed with just one "adjustable bolt 59"; Meanwhile, since it is a fully automatic device, the steel pipes on the material rack 31 may be of different lengths or uneven. To solve this problem, a "pre-feeding mechanism 32" is designed to deliver the steel pipes that are not in place to the designated position.

[0022] A synchronous shaft 21 is rotatably connected to the base 1 via bearings. Synchronous pulleys 22 are fixedly connected to both ends of the synchronous shaft 21. A synchronous pulley 22 is also connected to one side of the left spindle box 5, and a synchronous pulley 22 is also connected to one side of the right spindle box 2. The synchronous pulleys 22 and the synchronous pulleys 22 on the synchronous shaft 21 are connected by a synchronous belt. A main motor 23 is fixedly connected to the base 1. The main motor 23 is connected to the synchronous shaft 21. When the main motor 23 is started, it drives the synchronous shaft 21 to rotate. In turn, the synchronous pulley 22 and the synchronous belt work together to drive the main shaft in the left spindle box 5 and the right spindle box 2 to rotate, thereby driving the steel pipe to rotate.

[0023] The feeding mechanism 9 includes an L-shaped plate 24 slidably mounted on the feeding tailstock 8. A U-shaped frame 25 is fixedly connected to the L-shaped plate 24. L-shaped clamping plates 26 are symmetrically arranged on the U-shaped frame 25 and are slidably connected to the U-shaped frame 25. A tailstock clamping cylinder is mounted on the L-shaped plate 24 and is connected to the two L-shaped clamping plates 26. Activating the tailstock clamping cylinder drives the two L-shaped clamping plates 26 to move towards each other, thereby clamping the steel pipe. A feeding motor 27 is mounted on the feeding tailstock 8 and is connected to the L-shaped plate 24. Activating the feeding motor 27 drives the L-shaped plate 24 to move, thereby moving the steel pipe.

[0024] Two guide rollers 28 are longitudinally arranged on one side of the L-shaped clamp 26. Both guide rollers 28 are rotatably connected to the L-shaped clamp 26. When the L-shaped clamp 26 is moved, the guide rollers 28 contact and press the steel pipe. With this design, when rotating, the L-shaped clamp 26 can still use the guide rollers 28 to clamp the pipe without interfering with the normal rotation of the pipe. Furthermore, a lifting mechanism 29 is provided on the feeding tail frame 8 to lift the tail end of the steel pipe to ensure the concentricity of the pipe fitting. A material rack 31 is provided on one side of the feeding tail frame 8 for stacking steel pipes, and a pre-feeding mechanism 32 is provided on the material rack 31 for sending the steel pipes between the L-shaped plates 24.

[0025] The lifting mechanism 29 includes a support frame 33 fixedly connected to the feeding tailstock 8. The support frame 33 is fixedly connected to a lifting cylinder 34 for lifting lever 38. A movable plate 35 is fixedly connected to the extended end of the lifting cylinder 34 for lifting lever 38. A robot arm 36 is mounted on the movable plate 35, and a robot arm clamping cylinder 37 is mounted on the movable plate 35 to drive the robot arm 36 to close. Furthermore, a lifting bar 38 is clamped on the robotic arm 36. One end of the lifting bar 38 is located inside the steel pipe to support the tail end of the steel pipe. The lifting bar 38 can be replaced according to different pipe fittings.

[0026] The material rack 31 includes multiple sets of roller mechanisms 39 to support the unprocessed portion of a single steel pipe without interfering with the rotation of the pipe. Furthermore, a pipe material storage area 41 is provided on the material rack 31 for storing multiple pipe materials, and a pipe material waiting area 42 is provided on the material rack 31 for storing a single layer of pipe materials. A first lifting mechanism 43 is provided between the pipe material storage area 41 and the pipe material waiting area 42 for lifting the pipe fittings into the pipe material waiting area 42. A second lifting mechanism 44 is provided between the pipe material waiting area 42 and the roller mechanism 39 for lifting a single pipe fitting into the roller mechanism 39.

[0027] The pre-feeding mechanism 32 includes an L-shaped slide plate that is slidably connected to the material rack 31. A fixed clamp 46 is fixedly connected to the L-shaped slide plate, and a movable clamp 47 is rotatably connected to the L-shaped slide plate via a rotating shaft. A clamping cylinder 48 is rotatably connected to the L-shaped slide plate via a rotating shaft. The extended end of the clamping cylinder 48 is rotatably connected to the movable clamp 47. When the clamping cylinder 48 is activated, it drives the movable clamp 47 to deflect, thereby cooperating with the fixed clamp 46 to clamp the pipe fitting. Furthermore, a sliding cylinder 49 is fixedly connected to the material rack 31. The extended end of the sliding cylinder 49 is fixed to the L-shaped slide plate, which drives the L-shaped slide plate to move, thereby driving the pipe clamped by the movable clamp 47 to move and sending the pipe between the L-shaped clamps 26.

[0028] The roller mechanism 39 includes a movable roller 51 rotatably connected to the material rack 31, a shaft 2 rotatably connected to the material rack 31, a movable arm 53 rotatably connected to the shaft 2, an adjustable positioning roller 54 rotatably connected to one end of the movable arm 53, a movable arm 55 rotatably connected to the shaft 2, an adjustable positioning roller 56 rotatably connected to one end of the movable arm 55, and an adjustable mechanism 57 is provided on the material rack 31. The adjustable mechanism 57, the movable arm 53, and the adjustable positioning roller 56 are respectively rotatably connected by a connecting rod 58 through a rotating shaft. Furthermore, an adjustable bolt 59 connected to the adjustable mechanism 57 is provided on the material rack 31. By rotating the adjustable bolt 59, the distance between the movable roller 1 51, the adjustable positioning roller 1 54, and the adjustable positioning roller 2 56 can be adjusted to accommodate different pipe fittings.

[0029] The first lifting mechanism 43 includes a sliding cylinder 61 and a first lifting shaft 62 mounted on the material rack 31. The pipe is moved by the cooperation of the sliding cylinder 61 and the first lifting shaft 62. The second lifting mechanism 44 includes a sliding cylinder 63 and a second lifting shaft 64 mounted on the material rack 31. The pipe is moved by the cooperation of the sliding cylinder 63 and the second lifting shaft 64. In practical use, the entire bundle of steel pipes is hoisted to the "pipe storage area 41", then sent to the "pipe waiting area 42" by the first lifting mechanism 43, then sent to the "roller mechanism 39" by the "second lifting mechanism 44", then sent to the "tailstock clamping mechanism 7" by the "pre-feeding mechanism 32", and then sent to the main shaft of the right spindle box 2 by this mechanism. When the photosensitive switch at the spindle opening detects the steel pipe, the steel pipe is clamped and cut by the "cutting head mechanism 3". After completion, the "outer diameter plate 4" performs outer diameter turning. After completion, the main shaft of the left spindle box 5 moves to the right and clamps the turned steel pipe. At this time, the left and right spindles and the "feeding tailstock 8" work simultaneously to move the steel pipe to the left. After reaching the position, the "cutting plate 6" cuts the steel pipe. After completion, the main shaft of the left spindle box 5 moves to the right by one product position (which can be set); then the second product is cut; until the cutting between the two shafts is completed, the product is discharged from the center of the main shaft of the left spindle box 5 to the left, and then the above steps are repeated. This device also possesses the following characteristics; 1. Integrated electromechanical layout with a unique high-rigidity structural design.

[0030] 2) The main castings of this machine tool are all made of high-grade cast iron and have undergone two artificial aging treatments to ensure the stability and high rigidity of the machine tool body.

[0031] 3) All five guide rails of the left spindle box adopt high-precision HIWIN linear roller guide rails, which can bear large loads, have fast traverse speed, and have a long service life.

[0032] 4) The X / Z axis lead screws on the slide are all imported from THK, featuring high-precision, high-speed, and silent ball screws with zero backlash transmission, high rigidity, high precision, and long service life. This ensures the high motion rigidity and stability of the machine tool. The guide rails use brand-name high-precision cross-shaped guide rails, effectively guaranteeing the rigidity and precision requirements.

[0033] 5) Both spindles use short tapered roller bearings, which provide high speed and high rigidity. The right spindle adopts a belt pulley bypass design, making belt replacement very simple.

[0034] The 6-piece material rack 31 adopts a dual-shaft dual-lifting mechanism, which does not occupy other time. The main steel pipe support frame is a three-bearing self-centering design. When adjusting the size of the steel pipe, only one bolt needs to be tightened. Each rolling bearing can be freely adjusted in a centripetal state, which is fast and stable.

[0035] 7) It adopts an independent movable blade holder, which can be freely adjusted according to the size of the pipe material and the height of the product, and has good stability.

[0036] 8) It adopts a full-function CNC system, which is feature-rich and reliable. High-performance servo motors are used in the servo drive system to ensure stable mechanical movement during rapid traverse.

A rectangular plate 66 is fixedly connected to one end of the shaft 65. Two guide rollers 28 are rotatably connected to the rectangular plate 66 via a rotating shaft. A one-way linkage 67 is provided between the shaft 65 and the U-shaped frame 25. When the two L-shaped clamping plates 26 are moved and opened, the one-way linkage 67 drives the shaft 65 and the L-shaped clamping plate 26 to rotate 180 degrees, thereby actively replacing the two guide rollers 28 on one side of one L-shaped clamping plate 26. This allows the two guide rollers 28 to exchange positions, thus distributing wear and extending the service life of the device while improving the positioning effect. The one-way linkage 67 includes a worm gear 68 fixedly connected to one end of shaft three 65, shaft four 69 rotatably connected to L-shaped clamp plate 26, a worm 71 fixedly connected to one end of shaft four 69 and meshing with worm gear 68, a sliding groove 72 opened on U-shaped frame 25, one end of shaft four 69 passing through L-shaped clamp plate 26 and located in sliding groove 72 and slidably connected to its inner wall, and a gear plate 73 provided at one end of shaft four 69, a rack 74 fixedly connected to the inner wall of sliding groove 72, and a ratchet and ratchet assembly 75 provided between shaft four 69 and gear plate 73. During the movement of L-shaped clamp plate 26, after driving gear plate 73 to mesh with rack 74, the L-shaped clamp plate 26 continues to move, so as to drive gear plate 73 to roll along rack 74, thereby driving shaft four 69 to rotate, which in turn drives worm 71 to rotate, thereby driving worm gear 68 to rotate, and then driving shaft three 65 to rotate, so as to drive rectangular plate 66 to rotate. A self-locking motor is fixedly connected to the bottom of the U-shaped frame 25, and a gear plate 73 is also fixedly connected to the output shaft of the self-locking motor.
