Description

Technical Field

[0001] The utility model relates to the technical field of roller processing equipment, in particular to a roller double-end surface processing system. Background Art

[0002] High-end roller bearings are the core basic components of major technical equipment in key areas. High-precision rollers are the most core components of high-end roller bearings. The circular runout of the end face to the reference is an important precision indicator of the roller, which directly affects the distribution characteristics of the bearing lubricating medium and the life of the cage, and further affects the bearing temperature rise and rotational stability. Therefore, it is particularly important to achieve high-precision processing of the two end faces of the roller.

[0003] The clamping of rollers is the premise to ensure the machining accuracy of the two end faces of the rollers. For rollers made of ferromagnetic materials, different clamping methods are usually used in different processing methods and processes, mainly including fixed clamping and free clamping. Fixed clamping mainly includes three-jaw chuck clamping and electromagnetic clamping, which are commonly used in processing methods and processes such as turning single end face and grinding single end face; free clamping mainly places the roller in a specific fixture in a free state, which is commonly used in processing methods and processes such as double end face grinding and double end face grinding. The three-jaw chuck clamping method uses the rolling surface of the roller as the reference. One clamping can only realize the processing of a single end face of a roller. It is difficult to ensure the clamping accuracy. The secondary clamping will seriously affect the processing accuracy of the end face. It is impossible to realize the batch continuous processing of the two end faces of the roller, and the processing efficiency is low. When the electromagnetic clamping method is used, the two end faces of the roller are mutually referenced, and the single end faces of several rollers can be processed simultaneously. The processing of the other end face requires secondary clamping, which has higher requirements for clamping accuracy and electromagnetic platform accuracy. The processing efficiency is slightly higher than the three-jaw chuck clamping, and it is also impossible to realize the batch continuous processing of the two end faces of the roller. The free clamping processing method and process can realize the simultaneous processing of the two end faces of multiple rollers according to the size of the fixture, but the requirements for the fixture material, the matching accuracy of the fixture and the roller, the processing parameters and the processing accuracy of the equipment are extremely high. The processing accuracy of the two end faces of the roller with a large aspect ratio is extremely difficult to ensure. When non-magnetic materials such as engineering ceramics become a main material for bearing rollers, the limitations of the above clamping method are more prominent.

[0004] The core goal is to achieve high-efficiency, high-precision and consistent batch and integrated processing of the two end faces of the roller. The precision processing of the two end faces of the roller usually requires two processing steps: grinding and lapping. In the grinding process, double-end surface grinding is a processing method that can ensure the consistency of processing accuracy between end faces and batch accuracy between rollers, and can achieve batch processing of the two end faces of the roller in conjunction with automatic loading and unloading devices. However, this method has extremely high requirements on fixture accuracy, equipment accuracy and processing process parameters. At the same time, it is necessary to regularly adjust the accuracy of the grinding wheel to ensure the processing efficiency and processing accuracy of the two end faces of the roller. The time cost and economic cost of processing are extremely high. During the grinding process, double-plane grinding is a processing method that can further improve the processing accuracy between roller end faces and the batch accuracy consistency between rollers. This method can realize intermittent processing of two end faces of a certain number of rollers, but is affected by the roller material, roller size specifications and equipment processing principles. Special clamping tools and more precise control of processing parameters are required, otherwise it will cause the two end faces of the roller to "tilt", seriously damaging the processing accuracy of the two end faces; at the same time, if a more economical free abrasive processing form is adopted, the abrasive particles entering the gap between the rolling surface of the roller and the clamping tool will destroy the processing quality of the rolling surface; if a more economical fixed abrasive processing form is adopted, although the above situation is improved, it is necessary to regularly dress the fixed abrasive grinding disc, which has high time and economic costs.

[0005] Therefore, how to achieve high-efficiency, high-precision and consistent batch and integrated processing of the two end faces of bearing rollers of various materials and sizes has become a technical problem that needs to be solved urgently. Utility Model Content

[0076] Fig.15 FIG. 1 is an example diagram of the application principle of the roller double-end surface machining system according to an exemplary embodiment of the utility model, as shown in FIG. Fig.15 As shown, the application principle of the roller double-end surface machining system of this embodiment is as follows:

[0077] Step 1: Adjust the position of the movable bracket J21 as needed and fix the movable bracket J21 on the crossbeam J14 through multiple locking mechanisms J22; lift the tensioning bracket J31 by actuating the tensioning height adjustment cylinder J33, driving the tensioning wheel J323 in the tensioning angle adjustment mechanism J32 to tension the processing belt J5 for the first time; by axially moving the tensioning control part J324 in the direction of the tensioning wheel J323, the end of the tensioning control part J324 pushes the lower end of the second hinge J321 to rotate, so that the tensioning wheel J323 rotates synchronously with the lower end of the second hinge J321, and the processing belt J5 is fully tensioned;

[0078] Step 2: First, take the second fixed hole J232 on the longitudinal inclination adjustment plate J23 as the center of the circle, adjust the longitudinal inclination of the longitudinal inclination adjustment plate J23 as needed, and then lock and assemble the first arc groove J231 and the first locking hole J212 through the first locking member J233, and assemble the longitudinal inclination adjustment plate J23 at one end of the movable bracket J21 at the required longitudinal inclination. The longitudinal inclination adjustment plate J23 drives the clamp body J261 of the clamp J26 to present a certain longitudinal inclination. Then, take the third fixed hole J252 on the transverse inclination adjustment plate J25 as the center of the circle, adjust the transverse inclination of the clamp J26 as needed, and then lock and assemble the second arc groove J251 and the third locking hole 264 through the second locking member J265. The clamp connection part J262 drives the clamp body J261 to present a certain transverse inclination. At this point, the transverse inclination α and longitudinal inclination β of the processing belt J5 are adjusted;

[0079] Step 3: Start the clamping device to complete the high-precision, batch-based, and flexible clamping of the workpiece H. Then, the two drive motors K31 drive the processing devices J on the two processing device mobile platforms K to move toward each other. When the processing belts J5 of the two processing devices J are in micro-contact with the end surface of the workpiece H, the two processing device mobile platforms K stop moving, and the double-end surface processing system completes the tool setting.

[0080] Step 4: The driving motor J41 drives the driving wheel J44 to rotate through the transmission wheel group J42, and the fully tensioned processing belt J5 rotates towards each other at high speed. The workpiece H enters the processing area in turn under the drive of the clamping assembly A. The two processing belts J5 rotate towards each other to drive the workpiece H to rotate around its own axis, and the two end faces of the workpiece H are processed; thereafter, the processing belt J5 on one side is fixed, and the processing belt J5 on the other side is fed as needed, and the distance between the two processing belts J5 is shortened; after the processing belt J5 is fed once, it can be fed again only when the two end faces of all the workpieces H have been processed, until the length of the workpiece H reaches the required dimensional accuracy requirement, thereby realizing high-precision and consistent batch processing of the two end faces of the workpiece H.

[0081] The roller double end surface processing system of the utility model has the following beneficial technical effects through comprehensive structural design:

[0082] 1. Taking the extremely high-precision rolling surface of the roller as the reference, the clamping accuracy can be significantly improved; the roller is centered and pressed on the first and second clamping wheels by the third clamping wheel, and the roller is fixed in the radial direction, but can rotate around its own axis, realizing flexible clamping between fixed clamping and free clamping; through multiple clamping mechanisms set on the rotating base plate, continuous batch clamping of the roller is realized; in summary, high-precision, batch, and flexible clamping of bearing rollers of various materials and specifications is realized;

[0083] 2. The clamping plates of the processing device form a "wide front and narrow back" and "wide top and narrow bottom" arrangement in the horizontal and vertical directions. With the high-precision, batch-production, and flexible clamping device, when the processing belts used by the processing device move toward each other in the processing area, the rollers entering the processing area can be driven to rotate around their own axes in turn, so as to achieve high-precision processing of the two end faces of the rollers. After the processing device is fed once, it can be fed again only after the two end faces of all rollers are processed until the required dimensional accuracy is achieved, so as to achieve high-precision and consistent batch processing of the two end faces of the rollers.

[0084] 3. The processing belt used for processing has the characteristics of low cost and high processing efficiency. When the processing accuracy of the two end faces of the roller cannot meet the requirements, there is no need to trim the processing belt. Only by adjusting the processing position of the two end faces of the roller on the processing belt, the unused area on the processing belt can be used; if there is no unused area on the processing belt, a new processing belt can be replaced; thus, high-efficiency processing of the two end faces of the roller can be achieved;

[0085] 4. The processing accuracy of different processing steps of the two end faces of the roller can be achieved by replacing processing belts with different granularities. High-efficiency, high-precision and consistent batch and integrated processing of the two end faces of the roller can be achieved on this processing system.

[0086] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
