Description

Technical Field

[0001] The present invention relates to the technical field of milling processing, and in particular to processing equipment for a self-lubricating bearing structure. Background Art

[0002] With the rapid development of modern industry, the speed requirements for bearings are increasing, especially for large bearings. The rolling element and cage components of large bearings are very heavy. Under high-speed rotation, the cage is severely worn, even wearing away copper or iron chips. These fallen copper or iron chips cause great wear on the entire bearing, causing the bearing to fail prematurely due to severe wear, thus reducing the service life of the bearing. The materials of large bearing solid cages are mainly formed of brass and steel structures, and are available in three forms: inner diameter guide, outer diameter guide, and rolling element guide. The guide surface contacts other bearing components with very small clearances, making it difficult to achieve adequate lubrication under high-speed rotation, resulting in the wear of iron chips and rapid scrapping.

[0003] The prior art provides a milling device for bearing rings with ribs, with application number CN201911076702.7, comprising a workbench, a shelf for placing bearing rings, a positioning assembly for stabilizing at least two vertically stacked bearing rings on the shelf, and a forming tool capable of simultaneously processing ribs on two adjacent bearing rings on the shelf, wherein the shelf, the positioning assembly, and the forming tool are all disposed on the workbench. The invention provides a milling device for bearing rings with ribs, which can simultaneously mill ribs on vertically stacked bearing rings through the cooperation of the shelf, the positioning assembly, and the forming tool, thus avoiding processing one piece at a time and greatly improving processing efficiency.

[0004] However, the existing technology, especially this solution, still has the following problems: the milling device has a single processing type and cannot simultaneously process internal and external milling operations. In addition, the continuous production of processing equipment for bearing ring milling operations in the existing technology is limited, and there is a bottleneck in improving efficiency.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0019] The invention provides Figures 1 to 8 As shown, a processing equipment for a self-lubricating bearing structure is used to process a bearing ring 11, wherein circular lubrication gaps 12 are provided on the inner and outer walls of the bearing ring 11, and multiple groups of lubrication grooves 13 are provided on the outer and inner walls of the shaft along the lubrication gaps 12. The lubrication grooves 13 on the outer and inner walls are aligned, and a through hole is provided between the lubrication grooves 13 on the outer and inner walls. The lubricant for lubricating the inner and outer walls of the bearing ring 11 can enter the interior of the bearing ring 11 through the through hole, and the lubricant is distributed on the inner and outer walls of the bearing ring 11 for lubricating the bearing balls.

[0020] like Figure 1 and Figure 2 As shown, the provision of the lubricating gap 12 and the lubricating groove 13 allows the lubricant to exist for a longer period of time in the inner wall and the outer wall of the bearing ring 11. Specifically, the lubricant is provided as lubricating powder or lubricating oil.

[0021] The processing equipment includes a conveyor belt 26 and two sets of positioning cylinders 22. Two sets of positioning clamping wheels 24 are installed at the ends of the two sets of positioning cylinders 22. The two sets of positioning cylinders 22 position the bearing ring 11 on the conveyor belt 26 through the positioning clamping wheels 24. The positioning clamping wheels 24 are in contact with the outer wall of the bearing ring 11 and support the bearing ring 11 from the outside. Support rod 1 32 and two sets of slotting mechanisms, the slotting mechanism includes a milling tool for slotting operation, one side of support rod 1 32 is also connected to support rod 2 33 which rises and falls synchronously, and the bottom of support rod 2 33 is connected to a positioning cylinder 34 for internal support of the bearing ring 11; one set of slotting mechanisms is arranged at the bottom of support rod 1 32 and rises and falls with support rod 1 32, and performs inner wall milling and slotting operations on a bearing ring 11 positioned by the positioning clamping wheel 24, and the other set of slotting mechanisms performs outer wall milling and slotting operations on another bearing ring 11 supported by the positioning cylinder 34.

[0022] Working principle: Double-station parallel processing, station one is for inner wall processing: the positioning cylinder 22 drives the positioning clamping wheel 24 to clamp the outer wall of the bearing ring 11 to provide external support, and the milling tool at the bottom of the support rod 1 32 drops synchronously to mill and groove the inner wall of the bearing ring 11. Station two is for outer wall processing: support rod 2 33 drives the positioning cylinder 34 to insert into the inner hole of another bearing ring 11 to provide internal support, and another set of milling tools synchronously mills and grooves its outer wall. Synchronicity: support rod 1 32 and support rod 2 33 rise and fall in linkage to achieve strict synchronization of the processing actions of the two stations. Collaborative positioning mechanism, external positioning: the positioning clamping wheel 24 clamps the bearing ring 11 from both sides to limit radial displacement. Internal positioning: the positioning cylinder 34 is inserted into the inner hole of the bearing ring 11 to resist the radial force of milling and form a complementary constraint with the external clamping.

[0023] The inner and outer wall grooving is performed simultaneously on adjacent bearing rings 11, which increases production capacity per unit time compared to serial processing. Precision is enhanced, with external clamping and internal support forming a bidirectional rigid constraint to suppress machining vibration and ensure the position accuracy of the lubrication groove 13. The structure is simple and efficient, with support rod 1 32 and support rod 2 33 mechanically linked. Only a single drive source is required to control two sets of machining actions, reducing equipment complexity and cost. The two sets of positioning clamps 24 are designed with four-point clamping to enhance external support stability; the internal support function of the positioning cylinder 34 naturally resists milling radial forces to avoid workpiece deformation; the synchronous operation of the two stations directly reduces the single-piece machining cycle and improves efficiency.

[0024] Specifically, the conveyor belt 26 is configured as an intermittently operated belt conveyor, and the positioning cylinder 22 clamps and positions the bearing ring 11 when the conveyor belt 26 is stopped. Here, the positioning cylinder 22 and the positioning clamping wheel 24 have a positioning function in clamping the bearing ring 11.

[0025] The processing equipment performs the grooving operations on the inner and outer walls of the bearing ring 11 simultaneously, that is, when the processing equipment performs the grooving operations on the inner and outer walls of the bearing ring 11, the bearing ring 11 is located at different positions on the conveyor belt 26. You can choose to groove the inner wall of the bearing ring 11 first, or you can choose to groove the outer wall of the bearing ring 11 first. The grooving operations on the inner and outer walls of the same bearing ring 11 are performed at different positions on the conveyor belt 26.

[0026] However, in order to ensure production and processing efficiency, among the two adjacent bearing rings 11, when one bearing ring 11 is performing the inner wall grooving operation, the other bearing ring 11 is performing the outer wall grooving operation. Due to the synchronization of the descending support of the positioning cylinder 34, the clamping of the positioning clamping wheel 24, and the grooving operation of the grooving mechanism, the two bearing rings 11 both obtain better positioning and clamping effects during the inner and outer wall grooving processes.

[0027] like Figure 5 As shown, a pressing member 311 is mounted at the bottom of the second support rod 33. A positioning cylinder 34 is connected to the bottom of the pressing member 311. While the positioning cylinder 34 provides internal support for the bearing ring 11, the pressing member 311 presses down on the bearing ring 11 to achieve better positioning. Furthermore, a transition fit is provided between the positioning cylinder 34 and the inner wall of the bearing ring 11. While providing internal support for the bearing ring 11, the positioning cylinder 34 can also smoothly rise and disengage from the bearing ring 11 without affecting the subsequent transport of the bearing ring 11 on the conveyor belt 26.

[0028] like Figure 5 As shown, the pressing member 311 is configured as a cross structure. When the pressing member 311 is pressed on the top surface of the bearing ring 11, it is the limit position for the positioning cylinder 34 to descend. In addition to providing downward force to the bearing ring 11, the pressing member 311 also serves as a position limiting structure for the descent of the positioning cylinder 34.

[0029] The processing equipment includes a driving structure for driving the support rod 1 32 to move up and down. The support rod 1 32 is also equipped with a connecting bracket 31 for connecting the support rod 2 33, thereby realizing the synchronous lifting and lowering operation of the slotting mechanism and the positioning cylinder 34.

[0030] like Figure 3 As shown, the processing equipment also includes a base 21, and two sets of positioning cylinders 22 are installed on the base 21 in a symmetrical arrangement with a conveyor belt 26. The two sets of positioning cylinders 22 are located on both sides above the conveyor belt 26, so that the bearing ring 11 is clamped from both sides of the bearing ring 11 through the positioning clamping wheel 24. Specifically, the ends of the positioning cylinders 22 are provided with mounting blocks 23 for mounting the positioning clamping wheel 24. Figure 7 As shown, two sets of positioning clamping wheels 24 are installed on the mounting block 23, and a clearance groove 25 for making way for the bearing ring 11 is provided on the mounting block 23.

[0031] Specifically, the milling cutter includes a first milling cutter 36 and a second milling cutter 312. Drivers 1 39 and 2 310 are also mounted on the bottom of the connecting bracket 31. Driver 1 39 drives the first milling cutter 36 axially, while driver 2 310 drives the milling cutter's horizontal rotation. A lifting drive is also provided at the bottom of the first support rod 32. These drive mechanisms collectively enable the milling cutter to perform slotting operations. Another slotting mechanism includes multiple sets of second milling cutters 312. These sets of second milling cutters 312 are fed while the conveyor belt 26 is stationary to mill and slot the exterior of the bearing ring 11.

[0032] Further, such as Figure 4 and Figure 5 As shown, an adjustment seat 35 for mounting a milling cutter 36 is mounted at the bottom of the support rod 1 32. The adjustment seat 35 is provided with a mounting bearing 37, which is configured as a linear bearing. With the mounting bearing 37, the milling cutter can precisely move in the axial direction. Furthermore, the adjustment seat 35 is mounted to the bottom of the support rod 1 32 via a mounting seat 38. The adjustment seat 35 is rotatably mounted on the mounting seat 38.

[0033] The conveyor belt 26 is configured as a step-driven belt conveyor, and a positioning member for limiting the bearing ring 11 is provided on the conveyor belt. When the bearing ring 11 is placed on the conveyor belt, the positioning member fixes the position of the bearing ring 11 to prevent the bearing ring 11 from being displaced during the conveying process or falling off the conveyor belt 26, thereby affecting subsequent processing steps.

[0034] Specifically, such as Figure 7 and Figure 8 As shown, milling cutter 1 36 and milling cutter 2 312 define only two sets of lubrication grooves 13 on the inner and outer walls of bearing ring 11. Furthermore, positioning members on conveyor belt 26 can rotate bearing ring 11, enabling milling cutter 1 36 and milling cutter 2 312 to define multiple sets of lubrication grooves 13 on the inner and outer walls of bearing ring 11. After the first round of grooving of the inner and outer walls is completed, the positioning members can be used to rotate the bearing ring 11 90 degrees and then intermittently conveyed again via conveyor belt 26 for a second round of grooving of the inner and outer walls.

[0035] In summary, the present invention has the following comprehensive effects: The parallel processing mechanism uses intermittent stepping conveyor belt 26 to position adjacent bearing rings 11 at the inner wall processing station and outer wall processing station, respectively. At station one, the positioning cylinder 22 drives the positioning clamping wheel 24 to clamp the outer wall of the bearing ring 11 for external support, while the inner wall slotting mechanism's milling tool 1 36 creates a lubrication groove 13 on the inner wall. At station two, the positioning cylinder 34 is inserted into the inner hole of the bearing ring 11 for internal support, while the lower pressure member 311 compresses the top of the bearing ring 11. The outer wall slotting mechanism's milling tool 2 312 creates a lubrication groove 13 on the outer wall. Simultaneous positioning and processing: Positioning synchronization: The clamping action of the positioning clamping wheel 24, the lowering support of the positioning cylinder 34, and the feeding action of the slotting mechanism are performed simultaneously. The lower pressure member 311 compresses the top of the bearing ring 11 when the positioning cylinder 34 descends to its limit, enhancing stability. Slotting synchronization: Inner and outer wall milling are performed simultaneously, enabling parallel processing of adjacent bearing rings 11. Multiple sets of grooves are machined in stages, with only one set of lubrication grooves 13 being machined each time. After the initial machining, the positioning member of the conveyor belt 26 rotates the bearing ring 11 90 degrees. Through multiple cycles, multiple sets of lubrication grooves 13 are created on the inner and outer walls. Precision motion control: Inner wall grooving mechanism: Milling tool 1 36 achieves precise axial feed via linear bearings. Horizontal rotation is controlled by driver 2 310, with support rod 1 32 providing lift drive. Outer wall grooving mechanism: Multiple sets of milling tools 2 312 are fed synchronously to ensure efficient outer wall grooving.

[0036] Processing efficiency is significantly improved. Grooving of the inner and outer walls is performed simultaneously at adjacent workstations, eliminating the waiting time associated with traditional serial processing and doubling production capacity per unit time. The stepper drive of conveyor belt 26 is strictly aligned with the processing program, enabling continuous production. Positioning accuracy and stability are optimized with a dual positioning design: the outer locating clamp 24 provides multi-point clamping, while the inner locating cylinder 34 provides transitional support, creating internal and external rigid constraints. The cross-shaped structure of the lower pressure piece 311 provides vertical pressure to suppress processing vibration. Clamping errors are reduced: the transitional fit between the locating cylinder 34 and the bearing ring 11 ensures support stability while facilitating separation, preventing scratches on the workpiece. Consistent processing quality is guaranteed. Linear bearings ensure axial feed accuracy of the milling tool, preventing depth deviations in the lubrication grooves 13. The bearing ring 11 rotates precisely via the positioning element, achieving uniform distribution of multiple lubrication grooves 13 and ensuring consistent lubricant flow. Equipment compatibility and flexibility allow users to freely choose whether to process the inner or outer wall first to meet different process requirements. The adjustable seat 35 can be rotated to facilitate fine-tuning of the tool angle to accommodate bearing rings 11 of varying sizes. Production is highly automated. Positioning components on the conveyor belt 26 automatically secure and rotate the workpiece, reducing manual intervention. Positioning, supporting, and slotting operations are fully automated and performed simultaneously, reducing operational complexity. This equipment utilizes an innovative parallel processing architecture and collaborative positioning system to ensure machining accuracy while maximizing production efficiency. It is particularly suitable for mass production of self-lubricating bearing rings 11, which require multiple, repetitive processes.

[0037] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
