Description

Technical Field

[0001] The present invention relates to the technical field of parts processing, in particular to a burr removal device for bearing processing. Background Art

[0002] In bearing manufacturing, burr removal and chamfering are critical post-processing steps that impact product quality. Burrs are created during pre-processing processes like turning and grinding. If not thoroughly removed, they can lead to abnormal wear, noise, and premature bearing failure. Precise chamfering, on the other hand, eliminates stress concentration at the edges, improves bearing fatigue resistance, and ensures smooth entry of rolling elements into the raceways.

[0003] Currently, the industry generally adopts a step-by-step processing method, whereby deburring and chamfering processes are completed sequentially using independent equipment. However, this traditional model has significant drawbacks. First, step-by-step processing requires multiple clamping and positioning steps, which is not only time-consuming, but also easily introduces cumulative positioning errors during long-distance workpiece transportation, resulting in reduced processing accuracy. Second, existing double-sided processing equipment often uses a rigid linkage structure in which hydraulic push rods synchronously drive the tools on both sides. However, this design is difficult to adapt to the thickness tolerances of bearings of different specifications. When dealing with thin-walled bearings or high-precision products, the rigid linkage can easily lead to over-cutting or under-processing, directly affecting the bearing's assembly compatibility and service life.

[0004] Driven by the trend toward intelligent manufacturing and automated production, the bearing industry is increasingly in need of high-efficiency, high-precision, and multi-specification processing equipment. The shortcomings of existing technologies not only restrict the flexible upgrade of production lines but also constitute a technical bottleneck hindering the domestic substitution of high-end bearings. Therefore, a new solution that can address these shortcomings is urgently needed to overcome the efficiency and precision limitations of traditional processes and promote the development of intelligent and high-precision bearing manufacturing.

[0007] In a preferred embodiment of the present invention, the processing unit on the mounting base on one side includes, in sequence along the circumferential motion direction of the annular clamping unit: a deburring wheel for removing burrs from the bearing end surface; an angle grinding wheel for chamfering the deburred bearing end surface;

[0010] In a preferred embodiment of the present invention, the angle grinding wheel includes: a second connecting plate, an outer edge angle grinding ring fixedly connected to the second connecting plate, and an inner edge angle grinding ring.

[0011] In a preferred embodiment of the present invention, the annular clamping unit includes: a base shell rotatably connected to the rotating shaft, a connecting rod in a circumferential array on the outside of the base shell, a clamping assembly arranged at the end of the connecting rod, and several hydraulic pumps arranged on the side of the base shell away from the second drive motor and used to drive the clamping assembly to clamp or release the bearing to be processed.

[0012] In a preferred embodiment of the present invention, the clamping assembly includes: a hydraulic rod arranged at the output end of the hydraulic pump and slidingly connected to the connecting rod, two first driving rods rotatably connected to both sides of the end of the hydraulic rod, and two bearing clamps rotatably connected to the two first driving rods respectively; the middle section of the bearing clamp is rotatably connected to the connecting rod, and when the hydraulic rod telescopically slides relative to the connecting rod, the two first driving rods drive the clamping ends of the two bearing clamps to move closer or farther away from each other to achieve clamping and loosening of the bearing.

[0013] In a preferred embodiment of the present invention, a rubber pad is bonded to the clamping surface of the clamping claw.

[0014] In a preferred embodiment of the present invention, the clamping assembly further comprises: a pressure sensor provided at the clamping ends of the two bearing clamping jaws, and an overload protection module electrically connected to the pressure sensor; when the clamping pressure exceeds a set threshold, the overload protection module controls the hydraulic pump to release pressure and trigger an alarm.

[0015] In a preferred embodiment of the present invention, a limit track is provided on the upper end of the mounting bracket, and a limit slider matching the limit track is fixedly connected to the upper end surface of the mounting base facing the limit track.

[0016] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0017] (1) The present application significantly improves the axial movement stability and accuracy of the mounting base plate by setting a matching structure of a planetary roller nut and a first threaded screw in the processing device, and combining the guiding function of a limit slider and a limit rail; the planetary roller nut forms a point contact transmission with the first threaded screw through a torsion-resistant keyway structure, efficiently converting the rotational motion into pure axial displacement; the sliding cooperation of the limit slider and the limit rail further constrains the displacement trajectory of the mounting base plate, avoiding the offset problem caused by mechanical clearance or external disturbance; the design achieves millimeter-level positioning accuracy of the processing unit along the axial direction, enabling the processing unit to accurately approach or move away from the bearing on the clamping device, thereby ensuring the depth consistency of burr removal and chamfering processing; in traditional technology, axial adjustment relies on manual or low-precision drive mechanisms, which are prone to processing deviations due to operational errors or mechanical wear, while the present application effectively solves this problem through the coordinated control of planetary roller transmission and limit slider; in addition, the high-precision characteristics of axial adjustment enable the processing unit to maintain a stable processing posture under complex working conditions, significantly improving the processing accuracy of bearing end face burr removal and chamfer thickness, and providing reliable technical support for the production of high-precision bearings.

[0018] (2) The present application arranges the deburring wheel and the angle grinding wheel in sequence along the circumferential motion direction of the annular clamping unit, and ensures that the annular distribution trajectory of the processing unit is coaxial with the circumferential motion trajectory of the annular clamping unit, thereby realizing a continuous process of completing end face burr removal and chamfering processing of the bearing after one clamping and positioning; specifically, when the clamping device drives the bearing to rotate, the bearing passes through the processing stations of the deburring wheel and the angle grinding wheel in sequence, without the need to adjust the clamping position or replace the equipment; this layout not only shortens the processing cycle of a single bearing, but also significantly improves production efficiency through the mode of simultaneous double-sided processing; in traditional technology, double-sided processing needs to rely on multiple independent devices to complete separately, which has the problems of large equipment space occupation and repeated clamping that easily introduces errors; while the present application uses a coaxial trajectory design to make the motion trajectory of the processing unit and the clamping device highly matched, ensuring that the bearing is always in the best processing position during the rotation process, thereby avoiding surface quality fluctuations caused by clamping eccentricity or uneven processing displacement; in addition, the modular design of the annular processing unit supports multi-station collaborative operation, further improving the equipment's large-scale production capacity and process flexibility.

[0019] (3) The present application arranges a deburring wheel and an angle grinding wheel on a single-sided mounting base in sequence, and performs targeted processing on the outer and inner rings of the bearings respectively through the outer edge scraper and inner edge scraper of the bearing on the deburring wheel, and the outer edge angle grinding ring and inner edge angle grinding ring on the angle grinding wheel; the scraper contacts the end face of the bearing through high-speed rotation, and removes burrs by using rigid contact force, while the angle grinding ring realizes chamfering processing through flexible grinding; the processing devices at both ends can process both sides of the bearing simultaneously, forming a double-sided synchronous processing process mode; this design not only reduces the repeated clamping steps in the processing process, It also avoids the stress concentration problem caused by single-sided processing through double-sided simultaneous processing, thereby improving the overall strength and surface finish of the bearing; in traditional technology, double-sided processing needs to rely on multiple devices to complete it in sequence, which is prone to inconsistent processing quality due to parameter differences or clamping errors between devices; and this application ensures the consistency of processing parameters on both sides through the collaborative design of double-sided processing units, significantly improving the stability of processing quality; in addition, the combined structure of the scraper and the angle grinding ring can flexibly adjust the processing depth and angle according to different bearing specifications, further enhancing the adaptability of the device. (4) The clamping device of the present application realizes adaptive clamping and dynamic monitoring of the clamping force of the bearing through the linkage structure of the hydraulic rod, the first drive rod and the clamping claw, combined with the rubber pad to enhance the friction force, and integrates the pressure sensor and the overload protection module; the clamping claw is driven by the hydraulic rod and linked through the first drive rod to ensure the smoothness and controllability of the clamping action; the pressure sensor monitors the clamping force in real time, and triggers the hydraulic pump to release pressure and alarm when the clamping force exceeds the set threshold through the overload protection module, effectively preventing the deformation or damage of the bearing caused by over-tightening; traditional clamping devices mostly adopt a fixed clamping force design, which is difficult to adapt to the clamping requirements of bearings of different specifications, and lacks an overload protection function, which is easy to cause the workpiece to be scrapped due to improper clamping; and the present application uses an adaptive clamping and pressure feedback mechanism to not only improve the reliability of clamping, but also significantly reduce the risk of production accidents caused by clamping failure; in addition, the rubber pad design on the surface of the clamping claw further enhances the clamping stability, avoids the bearing offset problem caused by sliding, and provides a stable basic condition for high-precision processing. (5) This application realizes efficient processing of bearings of various specifications through a three-axis linkage structure of a double processing device and a single clamping axis, combined with the layout of modular processing units; the axial displacement of the mounting base plate is synchronously controlled in the double processing device, so that the processing units on both sides can process both sides of the bearing at the same time, significantly shortening the single processing cycle; in addition, the modular design supports the rapid replacement and parameter adjustment of the processing units, so that it can adapt to the processing requirements of bearings of different diameters; traditional equipment mostly adopts a single-station or fixed structure design, which is difficult to meet the batch processing requirements of bearings of various specifications, and the equipment adjustment takes a long time; and this application not only improves the versatility of the equipment through multi-axis collaboration and modular architecture, but also optimizes the processing efficiency through parametric control.

[0029] Example:

[0030] This scheme proposes a Figure 1-Figure 3 The high-precision bearing deburring device shown here, based on planetary roller transmission and multi-axis collaboration, is designed to achieve efficient deburring and chamfering of bearing end faces and inner and outer rings through a modular design and dynamic adjustment mechanism. The device consists of three major components: a mounting bracket, a processing unit, and a clamping device. Through the synergy of precision mechanical transmission and a hydraulic clamping system, it can meet the needs of batch processing of bearings of various specifications.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, a burr removal device for bearing processing includes: a mounting bracket 1, two processing devices 2 symmetrically arranged at both ends of the mounting bracket 1, and a clamping device 3 arranged between the two processing devices 2 for clamping the bearing to be processed.

[0032] Specifically, the processing device 2 includes: two first support frames 21 fixedly connected to the mounting bracket 1 by bolts, a first drive motor 22 installed on the first support frame 21 near the outer side, a first threaded screw 23 axially parallel to the bearing clamping direction and fixedly connected to the output end of the first drive motor 22 and rotatably connected to the two first support frames 21, a planetary roller nut 24 sleeved on the first threaded screw 23, a mounting base plate 25 fixedly connected to the outer periphery of the planetary roller nut 24, and four processing units 26 arranged in a circumferential ring along the mounting base plate 25.

[0033] Based on the configuration of the above-mentioned processing device 2, when the first drive motor 22 is in operation, it drives the first threaded screw 23 to rotate, thereby driving the mounting base plate 25 to move along the axial direction of the first threaded screw 23 under the action of the planetary roller nut 24, thereby controlling the mounting base plate 25 to drive the processing unit 26 axially toward or away from the clamping device 3, thereby achieving processing posture adjustment and simultaneous processing of multiple bearings by multiple processing units 26. A limit track 11 is provided at the upper end of the mounting bracket 1, and a limit slider 12 matching the limit track 11 is fixedly connected to the upper end surface of the mounting base plate 25 facing the limit track 11 to stabilize the displacement trajectory of the mounting base plate 25.

[0034] The core function of the processing device 2 is to achieve precise axial displacement and stable rotational drive of the processing unit 26. The first drive motor 22 serves as the power source, and its output end is fixedly connected to the first threaded screw 23, ensuring the stable transmission of rotational motion. The planetary roller nut 24 is mounted on the first threaded screw 23. Through its unique roller transmission structure, it efficiently converts the rotational motion of the threaded screw into linear motion, with the characteristics of high precision, high rigidity and low friction. The mounting base 25 is fixedly connected to the outer periphery of the planetary roller nut 24. As the planetary roller nut 24 moves axially, it drives the processing unit 26 to accurately approach or move away from the clamping device 3.

[0035] The provision of the limiting rail 11 and limiting slider 12 further enhances the stability and linearity of the displacement of the mounting base 25. The limiting rail 11 is fixed to the upper end of the mounting bracket 1, while the limiting slider 12 is fixed to the upper end surface of the mounting base 25 and mates with the limiting rail 11. As the mounting base 25 moves axially, the limiting slider 12 slides within the limiting rail 11, effectively preventing the mounting base 25 from shifting or shaking during movement, ensuring the precise displacement trajectory of the machining unit 26.

[0036] The clamping device 3 is responsible for stably clamping and rotating the bearing to be processed, ensuring that the bearing maintains a precise axial position and a stable rotational speed during processing. The second support frame 31 serves as the foundational structure of the clamping device 3, supporting the weight and forces of the entire clamping system. A rotating shaft 32 is mounted between the second support frames 31 and is driven by a second drive motor 33. An annular clamping unit 34 is fixedly connected to the rotating shaft 32 and rotates with it, driving the clamping assembly 343 and the bearing to be processed in a circular motion.

[0037] The annular clamping unit 34 comprises a base housing 341, connecting rods 342, a clamping assembly 343, and a hydraulic pump 344. The base housing 341 is rotatably connected to the rotating shaft 32 via bearings, forming the main structure of the clamping device 3. Connecting rods 342 are arranged in a circular pattern around the outside of the base housing 341, with the clamping assembly 343 located at their ends. The hydraulic pump 344 is fixed to the side of the base housing 341 away from the second drive motor 33. The hydraulic rod drives the clamping assembly 343 to clamp and release the bearing.

[0038] The clamping assembly 343 is a key component for achieving stable clamping of the bearing, and includes a hydraulic rod, a first drive rod, and a bearing clamp. The hydraulic rod is arranged at the output end of the hydraulic pump 344 and is slidably connected to the connecting rod 342. The first drive rod is rotatably connected to both sides of the end of the hydraulic rod, and the bearing clamp is rotatably connected to the other end of the first drive rod. The middle section of the bearing clamp is rotatably connected to the connecting rod 342 to form a lever mechanism. When the hydraulic rod telescopes and slides, the transmission of the first drive rod drives the clamping ends of the two bearing clamps to move closer or farther away from each other, thereby achieving the clamping and loosening of the bearing.

[0039] The clamping surface of the clamping claw is bonded with a rubber pad. This rubber pad has good elasticity, which can enhance the clamping force on the bearing while preventing damage to the bearing surface during the clamping process. In addition, the clamping assembly 343 is also equipped with a pressure sensor and an overload protection module. The pressure sensor monitors the clamping force in real time and feeds the data back to the control system. When the clamping force exceeds the set threshold, the overload protection module quickly controls the hydraulic pump 344 to release pressure and triggers an alarm to prevent deformation or damage to the bearing due to excessive clamping force.

[0040] The machining units 26 are arranged in a circular pattern around the mounting base 25. The machining units 26 on one side of the mounting base 25 include a deburring wheel 261 and an angle grinding wheel 262, arranged in the direction of the circumferential motion of the annular clamping unit 34. The deburring wheel 261 is used to remove burrs from the bearing end surface, while the angle grinding wheel 262 is used to chamfer the deburred bearing end surface.

[0041] Deburring wheel 261 includes a first connecting disc, a bearing outer edge scraper, and a bearing inner edge scraper. The first connecting disc is fixed to the mounting base plate 25 via a flange connection. The bearing outer edge scraper and inner edge scraper are respectively fixed to the first connecting disc and are used to scrape burrs from the end faces of the bearing outer and inner rings. Angle grinding wheel 262 includes a second connecting disc, an outer edge angle grinding ring, and an inner edge angle grinding ring. The second connecting disc is also fixed to the mounting base plate 25 via a flange connection. The outer edge angle grinding ring and inner edge angle grinding ring are respectively fixed to the second connecting disc and are used to chamfer the edges of the bearing outer and inner rings.

[0042] The machining unit 26 also includes a third drive motor 263 for driving the deburring wheels 261 and the angle grinding wheels 262. Multiple third drive motors 263 can be provided, corresponding to the number of deburring wheels 261 and angle grinding wheels 262. Alternatively, a single third drive motor 263 can be provided, simultaneously driving multiple deburring wheels 261 and angle grinding wheels 262 via a conventional transmission chain. This design ensures that the machining unit 26 can perform efficient and precise deburring and chamfering on multiple bearings simultaneously.

[0043] Working principle:

[0044] Clamping Process: When clamping device 3 is activated, hydraulic pump 344 pushes the hydraulic rod to slide along connecting rod 342. Through the interlocking action of the first drive rod, the bearing jaws gradually clamp the bearing under real-time monitoring by the pressure sensor. Rubber pads on the clamping jaws enhance friction, ensuring the bearing remains stable during processing. If the clamping force exceeds the preset value, the overload protection module responds quickly, controlling hydraulic pump 344 to release pressure and triggering an alarm to prevent damage to the bearing due to over-clamping.

[0045] Machining posture adjustment: The first drive motor 22 rotates the first threaded screw 23. The planetary roller nut 24, constrained by the torsion-resistant keyway structure, converts this rotational motion into pure axial displacement. The mounting base 25, thanks to the precise coordination of the limit slider 12 and the limit rail 11, moves stably in the axial direction, driving the machining unit 26 to precisely approach or retreat from the bearing being machined, enabling fine-tuning of the machining posture. This process ensures the proper spacing between the machining unit and the bearing, ensuring efficient and accurate subsequent machining.

[0046] Deburring: The third drive motor 263 drives the deburring wheel 261 at high speed. The outer and inner scrapers contact the rotating outer and inner rings of the bearing, respectively, to remove burrs from the end faces. The deburring wheel's speed, material, and scraper shape are optimized for the bearing material and burr characteristics, ensuring efficient and thorough burr removal while minimizing damage to the bearing surface.

[0047] Chamfering: After deburring, the bearing rotates with the annular clamping unit 34 to the angle grinding wheel 262. The outer and inner angle grinding rings finely chamfer the edges of the bearing outer and inner rings. This chamfering process not only eliminates stress concentration at the edges, improving the bearing's fatigue resistance, but also ensures smooth entry of the rolling elements into the raceways, extending the bearing's service life.

[0048] Double-sided simultaneous machining: The machining units (2) at both ends of the device process both sides of the bearing simultaneously. This design significantly improves machining efficiency, reduces equipment footprint and the cumulative errors caused by repeated clamping, and ensures consistent machining quality on both sides of the bearing.

[0049] Throughout the entire machining process, the bearings sequentially pass through deburring and chamfering stations as the annular clamping unit 34 rotates. The circular trajectory of the machining unit 26 is coaxial with the circular trajectory of the annular clamping unit 34, enabling multiple bearings to be machined simultaneously at different positions. This layout enables automated processes, significantly shortens machining cycles, improves production efficiency, and meets the modern manufacturing industry's demand for efficient and precise machining. Furthermore, the automated process reduces human intervention, improves the stability of machining quality, reduces production costs, and enhances the company's market competitiveness in the bearing machining field.

[0050] To summarize, the present application realizes efficient and high-precision bearing burr removal and chamfering through the coordinated control of planetary roller transmission and limit slider 12, coaxial trajectory design of annular processing unit 26, modular layout of double-sided processing unit 26, adaptive clamping and pressure feedback mechanism, multi-axis collaboration and modular architecture and integration of intelligent protection system.
