Description

Technical Field

[0002] In the machinery manufacturing industry, bearings, as key components in rotating machinery, directly affect the operating quality and lifespan of mechanical equipment. The bearing ring is one of the core components of a bearing, and its accuracy and flatness have a crucial impact on the working performance of the entire bearing. Therefore, during the production process of bearing rings, high-precision grinding of the outer diameter is a key step to ensure product quality.

[0003] The traditional bearing ring outer diameter grinding equipment mainly has the following problems: 1) In the traditional method, workers need to frequently load and unload workpieces, manually adjust the distance between the grinding wheel and the workpiece, and lack an effective limiting structure for the ring, which not only increases labor intensity but also restricts the improvement of production efficiency and processing quality; 2) Due to the large size differences among different types of bearing rings, traditional equipment can often only process products within a specific size range. When encountering new models or special requirements, it is necessary to redesign fixtures and adjust the process flow, resulting in insufficient flexibility; 3) With the increasingly obvious trend of the transformation of the manufacturing industry towards intelligence, some existing grinding equipment lacks sufficient automation functions and cannot meet the pursuit of efficient and stable production in modern factories, as well as the need to reduce interference from human factors.

[0032] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

It includes a bottom plate 1 and a mounting frame 10 fixedly installed thereon, and further includes:

A drive assembly for driving the drive shaft 30 to rotate is also installed on the mounting bracket 10.

[0036] An auxiliary clamping and transferring assembly is installed on the bottom plate 1. The auxiliary clamping and transferring assembly is used to sleeved the workpiece to be machined ring 36 on the bearing cylinder 5, assist in clamping it during the grinding process of the workpiece to be machined ring 36, and remove the workpiece to be machined ring 36 after grinding from the bearing cylinder 5.

[0037] In the embodiment of the present invention, through the setting of the auxiliary clamping and transferring assembly, it can sleeve the workpiece to be machined ring 36 on the bearing cylinder 5, assist in clamping it during the grinding process of the workpiece to be machined ring 36, and remove the workpiece to be machined ring 36 after grinding from the bearing cylinder 5. After the workpiece to be machined ring 36 is sleeved on the bearing cylinder 5, the control assembly is used to control the abutting and fixing assembly, so as to drive the abutting and fixing assembly to abut and fix the inner ring of the workpiece to be machined ring 36, realizing the central stability of the whole workpiece to be machined ring 36. Start the drive assembly to drive the drive shaft 30 to rotate. Using the transmission of the gears, the grinding wheel 14 and the bearing cylinder 5 rotate in the same direction, and the distance between the grinding wheel 14 and the outer surface of the workpiece to be machined ring 36 is adjusted through the distance adjusting assembly, realizing reliable control of the grinding. With the auxiliary clamping and transferring assembly driving the workpiece to be machined ring 36 to move, continuous grinding operations of multiple workpieces to be machined rings 36 can be realized, improving the processing efficiency. In addition, the diameters of the gear a9, gear b15, gear d43 and gear c29 can be changed as required, so as to adjust the relative speed of the grinding wheel 14 and the bearing cylinder 5, meeting the high-efficiency grinding requirements of different models of workpieces to be machined rings 36, and having a wide range of applications.

[0038] Such as Figure 1 、 Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, the abutting and fixing assembly includes a plurality of fixing plates 40 slidably arranged circumferentially and uniformly on the bearing cylinder 5.

A bushing 44 is also fixed on the inner side of the bearing cylinder 5, and the bushing 44 is slidably connected with the central rod 45 to improve the stability of the central rod 45. A stabilizing cylinder b47 slidably connected with the central rod 45 is fixed on the inner side of one end of the bearing cylinder 5 close to the fixing plate 40, and the stability of the central rod 45 is further improved through the stabilizing cylinder b47.

[0040] The control assembly includes a push-pull cylinder b4 coaxially arranged with the central rod 45. The end of the telescopic mandrel of the push-pull cylinder b4 is rotatably connected with one end of the central rod 45. The cylinder body of the push-pull cylinder b4 is also fixedly connected with the mounting frame 10 through a load-bearing frame a3. By controlling the expansion and contraction of the push-pull cylinder b4, the transmission of the central rod 45 and the power rod 46 can be utilized to drive the plurality of fixing plates 40 to expand and contract synchronously, so as to complete the centering and fixing of the workpiece to be machined, the sleeve 36, and the arrangement of the rolling balls a41 is beneficial to the installation and removal of the workpiece to be machined, the sleeve 36.

[0041] It should be noted that in order to enable the workpiece to be machined, the sleeve 36, to rotate with the bearing cylinder 5, the rolling balls a41 can be installed in a damping manner to ensure the grinding and moving performance of the workpiece to be machined, the sleeve 36. In addition, by using the abutting force of the fixing plate 40 on the workpiece to be machined, the sleeve 36, the transmission friction of the bearing cylinder 5, and the grinding friction of the grinding wheel 14, etc., the workpiece to be machined, the sleeve 36, can also be rotated to ensure the thoroughness of the grinding of the outer surface of the workpiece to be machined, the sleeve 36.

[0042] As Figures 1-3 As shown, as a preferred embodiment of the present invention, the distance adjusting assembly includes a push-pull cylinder c13 hinged to one end of the rocker arm 28 away from the stabilizing cylinder a12. The end of the cylinder body of the push-pull cylinder c13 is hinged with a load-bearing frame c11. One end of the load-bearing frame c11 is fixedly connected with the mounting frame 10. By controlling the expansion and contraction of the push-pull cylinder c13, the rocker arm 28 can be driven to rotate around the stabilizing cylinder a12, and the transmission between the gear b15 and the gear c29 is not affected, which is stable and reliable.

[0043] The driving component includes a load-bearing frame b8 fixed to the mounting frame 10. An electric motor a6 and a transmission 7 are respectively fixed on the load-bearing frame b8. The output end of the electric motor a6 is fixedly connected to the input end of the transmission 7, and the output end of the transmission 7 is fixedly connected to one end of the drive shaft 30. By driving the electric motor a6 and shifting gears by the transmission 7, the drive shaft 30 can be stably driven to rotate.

[0044] Regarding the detachable fixing structure of the grinding wheel 14, specifically: a fixing disk 33 is fixed on the grinding shaft 16 on the side of the grinding wheel 14 close to the gear b15. A movable disk 32 is slidably arranged on the grinding shaft 16 on the other side of the grinding wheel 14. A fixing nut 31 threadedly connected to the grinding shaft 16 is further arranged on the side of the movable disk 32 away from the grinding wheel 14. By tightening the fixing nut 31, the grinding wheel 14 can be locked and fixed by the cooperation of the movable disk 32 and the fixing disk 33, which is convenient for the disassembly, maintenance, replacement, etc. of the grinding wheel 14.

[0045] Such as Figure 1 、 Figure 3 、 Figure 4 and Figure 6As shown, as a preferred embodiment of the present invention, the auxiliary clamping and transferring assembly includes a middle plate 23 slidably arranged on the bottom plate 1, and a push-pull cylinder a2 for driving the middle plate 23 to move is also fixed on the bottom plate 1; a plurality of push-pull cylinders d22 are fixed on the upper side of the middle plate 23, and the end of the telescopic core shaft of the push-pull cylinder d22 is fixed with an upper plate 21, and two adjustment plates 27 are slidably arranged on the upper side of the upper plate 21, and a bidirectional lead screw a39 is threadedly connected to the middle part of the two adjustment plates 27, and a load-bearing frame e25 is rotatably installed at both ends of the bidirectional lead screw a39, and the load-bearing frame e25 is fixed on the upper plate 21, and one of the load-bearing frames e25 is also fixed with a motor c24 that is transmission-connected to the bidirectional lead screw a39; an installation box 37 is fixed on the upper end of the adjustment plate 27, and the side where the two installation boxes 37 are close to each other is an open structure, and a bidirectional lead screw b48 is rotatably arranged on the inner side of the installation box 37, and an end gear 3 is fixed to one end of the bidirectional lead screw b48 8. A clamping plate 42 is threadedly connected to both sides of the bidirectional lead screw b48, and a ball b49 is installed on the end of the two clamping plates 42 that are close to each other. The two clamping plates 42 are used to clamp the two end surfaces of the ring 36 to be processed; two load-bearing frames d19 are also fixed on the upper plate 21, and a long shaft gear 17 is rotatably installed between the two load-bearing frames d19, and a motor b18 that is transmission-connected to the long shaft gear 17 is also fixed on one of the load-bearing frames d19, and the long shaft gear 17 is meshingly connected with the two end gears 38; a supporting plate 35 with a concave arc in the middle is also provided between the two adjusting plates 27, and push-pull cylinders e34 are fixed on the lower sides of both ends of the supporting plate 35, and the lower ends of the push-pull cylinders e34 are fixed on the upper plate 21, and the ring 36 to be processed is supported by the supporting plate 35, which is conducive to reliable loading and unloading. During grinding, the supporting plate 35 is separated from the ring 36 to be processed, and does not affect the grinding operation of the ring 36 to be processed.

[0046] Among them, the teeth of the end gear 38 (also called the end face gear) are not distributed along the axis direction, but are located in a plane perpendicular to the rotation axis. This gear is mainly used to realize the power transmission between two non-parallel and non-intersecting axes, usually one of which is vertical and the other is horizontal, which will not be described in detail. When the mounting box 37 rotates, the two end gears 38 rotate in opposite directions, which can be satisfied by only arranging the threads of the two bidirectional lead screws b48 in a corresponding manner. The motion states of the two sets of clamping plates 42 are consistent, which will not be described in detail.

[0047] Preferably, a plurality of guide rails a20 parallel to the supporting cylinder 5 are fixed on the base plate 1, and the lower side of the middle plate 23 is slidably connected to the guide rails a20; the cylinder body of the push-pull cylinder a2 is fixedly connected to the base plate 1, and the end of the telescopic core shaft of the push-pull cylinder a2 is fixedly connected to the middle plate 23.

[0048] Preferably, a plurality of guide rails b26 perpendicular to the bearing cylinder 5 are further fixed on the upper plate 21, and the lower end of the adjusting plate 27 is slidably connected to the guide rails b26; the bidirectional lead screw a39 is arranged parallel to the guide rails b26, and when the bidirectional lead screw a39 rotates, the two adjusting plates 27 approach or move away from each other.

[0049] Preferably, the clamping plate 42 is also slidably connected to the inner cavity and the open end of the installation box 37. To further improve the stability of the clamping plate 42, a guide rod 50 is fixed in the inner cavity of the installation box 37, and the two clamping plates 42 are both slidably connected to the guide rod 50; the bidirectional lead screw b48 is parallel to the bearing cylinder 5, and when the bidirectional lead screw b48 rotates, the two clamping plates 42 on it approach or move away from each other.

[0050] In specific applications, the push-pull cylinder a2 and the push-pull cylinder d22 can horizontally and vertically transfer the upper plate 21. The horizontal transfer facilitates the entry and exit of the to-be-processed ring 36 into and out of the bearing cylinder 5, and the vertical transfer enables the ball b49 to correspond to to-be-processed rings 36 of different models, improving the reliability of clamping; the rotation of the bidirectional lead screw a39 is driven by the motor c24, and the distance between the two adjusting plates 27 is adjusted, making the clamping plate 42 more suitable for the to-be-processed ring 36; the rotation of the long shaft gear 17 is driven by the motor b18, thereby driving the end gear 38 to rotate. The cooperation between the long shaft gear 17 and the end gear 38 can adapt to the distance change between the two adjusting plates 27, ensuring continuous meshing transmission; the rotation of the two bidirectional lead screws b48 can enable the two groups of clamping plates 42 to clamp the end face of the to-be-processed ring 36, facilitating the transfer of the to-be-processed ring 36 and the limiting and movement during grinding.

[0051] In the above embodiments of the present invention, a bearing ring grinding and processing device is provided, and the working principle is as follows:

[0052] The to-be-processed ring 36 is first brought to the bearing cylinder 5 by the auxiliary clamping and transfer assembly and is successfully sleeved onto the bearing cylinder 5. Then, the control assembly is started, and the push-pull cylinder b4 pushes the central rod 45 to move, driving a plurality of fixing plates 40 to expand outward via the power rod 46, abutting and fixing the inner ring of the to-be-processed ring 36 to ensure the centering and stability of the to-be-processed ring 36 on the bearing cylinder 5.

[0053] The motor a6 in the driving assembly is started, and after the speed is adjusted by the transmission 7, the driving shaft 30 is driven to rotate. The gear c29 on the driving shaft 30 meshes with the gear b15 on the grinding shaft 16, causing the grinding wheel 14 to rotate; at the same time, the gear a9 on the driving shaft 30 meshes with the gear d43 on the bearing cylinder 5, causing the bearing cylinder 5 to also rotate in the same direction, realizing the co-rotation with different speeds of the grinding wheel 14 and the bearing cylinder 5.

[0054] The push-pull cylinder c13 in the distance adjustment assembly controls the position change of the rocker arm 28, thereby adjusting the distance between the grinding wheel 14 and the outer surface of the to-be-machined ring 36 to adapt to different grinding requirements and ensure grinding accuracy. The grinding wheel 14 rotates and approaches the outer surface of the to-be-machined ring 36 for grinding operations. The auxiliary clamping and transfer assembly can continue to provide additional support and stability for the to-be-machined ring 36 during the grinding process to ensure the grinding effect.

[0055] After grinding a set of to-be-machined rings 36, the auxiliary clamping and transfer assembly will remove the ground rings from the carrier cylinder 5 and prepare the next set of to-be-machined parts to support continuous production.

[0056] In addition, by replacing or adjusting the diameters of the gears (gear a9, gear b15, gear c29, gear d43), the relative rotational speeds of the grinding wheel 14 and the carrier cylinder 5 can be changed to adapt to the high-efficiency grinding requirements of different models of to-be-machined rings 36.

[0057] The entire system design aims to improve grinding efficiency, accuracy, and adapt to to-be-machined rings 36 of various sizes and specifications, while ensuring the convenience of operation.

[0058] The control of each component can use the PLC controller disclosed in the prior art. The models and circuit connections of each component are not specifically limited and can be flexibly set during actual application. For example, the push-pull cylinders a2, b4, c13, d22, and e34 can use hydraulic cylinders or electric telescopic cylinders.

[0059] The circuits, electronic components, and modules involved are all prior art and can be fully realized by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as within the scope described in this specification.

[0061] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
