When encountering new models or special requirements, it is necessary to redesign the fixture and adjust the process flow, resulting in insufficient flexibility; 3) As the trend of manufacturing industry transformation towards intelligence becomes increasingly obvious, some existing grinding equipment lacks sufficient automation functions and cannot meet the modern factory's pursuit of efficient and stable production, as well as the need to reduce interference from human factors.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1-Figure 5 As shown, a bearing ring grinding processing equipment provided by an embodiment of the present invention is mainly used for grinding the outer diameter of the ring 36 to be processed, that is, grinding the outer surface of the ring 36 to be processed to ensure the accuracy and flatness of the outer diameter size, including a base plate 1 and a mounting frame 10 fixed thereon, and also including: The bearing cylinder 5 is rotatably mounted on the mounting frame 10.

A grinding wheel 14 for grinding the outer surface of the processing ring 36 can be detachably fixed on the grinding shaft 16. A distance adjustment component is also installed between the mounting frame 10 and the rocker arm 28. The distance adjustment component is used to adjust the distance between the grinding wheel 14 and the outer surface of the processing ring 36; a gear a9 is also fixed on the end of the driving shaft 30 away from the gear c29, and a gear d43 meshing with the gear a9 is fixed on the bearing cylinder 5; a driving component for driving the driving shaft 30 to rotate is also installed on the mounting frame 10; The auxiliary clamping and transferring assembly is installed on the base plate 1, and is used to sleeve the ring 36 to be processed on the supporting tube 5, and to assist in clamping the ring 36 to be processed during the grinding process, and to remove the ring 36 to be processed from the supporting tube 5 after grinding.

[0025] In the embodiment of the present invention, by setting the auxiliary clamping and transferring assembly, the ferrule 36 to be processed can be sleeved on the carrier tube 5, and the ferrule 36 to be processed can be auxiliary clamped during the grinding process, and the ferrule 36 to be processed can be removed from the carrier tube 5 after grinding. After the ferrule 36 to be processed is sleeved on the carrier tube 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 ferrule 36 to be processed, so as to achieve the centering and stability of the ferrule 36 to be processed as a whole. The driving assembly is started to drive the driving shaft 30 to rotate, and the grinding wheel 14 and the carrier tube 5 rotate in the same direction by the transmission of the gears, and the distance between the grinding wheel 14 and the outer surface of the ferrule 36 to be processed is adjusted by the distance adjusting assembly, so as to achieve reliable control of grinding, and the auxiliary clamping and transferring assembly is used to drive the ferrule 36 to be processed to move, so as to achieve continuous grinding of multiple ferrules 36 to be processed, thereby improving the processing efficiency. In addition, the diameters of gear a9, gear b15, gear d43 and gear c29 can be changed as needed, thereby adjusting the relative speed of the grinding wheel 14 and the carrier tube 5 to meet the efficient grinding requirements of different models of the processing rings 36, and the application is wide.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, as a preferred embodiment of the present invention, the abutment fixing assembly includes a plurality of fixing plates 40 circumferentially and evenly distributed and slidably arranged on the supporting tube 5, a plurality of rolling balls a41 are evenly installed on the outer surface of the fixing plate 40, a center rod 45 is provided in the middle of the inner side of the supporting tube 5, and a plurality of power rods 46 are hinged between the center rod 45 and the fixing plate 40.

[0027] Preferably, multiple power rods 46 are arranged in parallel and evenly distributed, which is conducive to the movement of the center rod 45 and stably drives the fixed plate 40 to extend and retract through the power rod 46; a shaft sleeve 44 is also fixed to the inner side of the bearing tube 5, and the shaft sleeve 44 is slidably connected to the center rod 45 to improve the stability of the center rod 45; a stabilizing tube b47 slidably connected to the center rod 45 is fixed to the inner side of one end of the bearing tube 5 close to the fixed plate 40, and the stability of the center rod 45 is further improved by the stabilizing tube b47.

[0028] The control component includes a push-pull cylinder b4 coaxially arranged with the center rod 45, the telescopic core shaft end of the push-pull cylinder b4 is rotatably connected to one end of the center rod 45, and the cylinder body of the push-pull cylinder b4 is also fixedly connected to the mounting frame 10 through the load-bearing frame a3. By controlling the extension and retraction of the push-pull cylinder b4, the transmission of the center rod 45 and the power rod 46 can be utilized to drive multiple fixed plates 40 to extend and retract synchronously, thereby completing the centering fixation of the ring 36 to be processed, and the arrangement of the rolling ball a41 is conducive to the installation and removal of the ring 36 to be processed.

[0029] It should be noted that, in order to enable the ferrule 36 to be processed to rotate with the bearing tube 5, the ball a41 can be installed in a damping manner to ensure the grinding and moving performance of the ferrule 36 to be processed. In addition, the ferrule 36 to be processed can also be rotated by utilizing the abutment force of the fixed plate 40 on the ferrule 36 to be processed, the transmission friction of the bearing tube 5 and the grinding friction of the grinding wheel 14, thereby ensuring the thoroughness of the grinding of the outer surface of the ferrule 36 to be processed.

[0030] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the distance adjustment assembly includes a push-pull cylinder c13 hinged to the end of the rocker arm 28 away from the stabilizing cylinder a12, and the cylinder end of the push-pull cylinder c13 is hinged with a load-bearing frame c11, and one end of the load-bearing frame c11 is fixedly connected to the mounting frame 10. The rocker arm 28 can be driven to rotate around the stabilizing cylinder a12 by controlling the extension and retraction of the push-pull cylinder c13, and the transmission between the gear b15 and the gear c29 is not affected, which is stable and reliable.

[0031] The driving assembly includes a load-bearing frame b8 fixed on the mounting frame 10, and a motor a6 and a transmission 7 are respectively fixed on the load-bearing frame b8. The output end of the 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 driving shaft 30. Through the drive of the motor a6 and the speed change of the transmission 7, the driving shaft 30 can be stably driven to rotate.

[0032] As for the detachable fixing structure of the grinding wheel 14, specifically: a fixed plate 33 is fixed on the grinding shaft 16 on the side of the grinding wheel 14 close to the gear b15, and a movable plate 32 is slidably provided 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 also provided on the side of the movable plate 32 away from the grinding wheel 14. By locking the fixing nut 31, the grinding wheel 14 can be locked and fixed by the cooperation of the movable plate 32 and the fixed plate 33, which is convenient for disassembly, maintenance and replacement of the grinding wheel 14.

[0033] like 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.

[0034] 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.

[0035] 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.

[0036] Preferably, a plurality of guide rails b26 perpendicular to the supporting tube 5 are fixed on the upper plate 21, and the lower end of the adjustment plate 27 is slidably connected to the guide rail b26; the bidirectional lead screw a39 is arranged parallel to the guide rail b26, and when the bidirectional lead screw a39 rotates, the two adjustment plates 27 approach or move away from each other.

[0037] Preferably, the clamping plate 42 is also slidably connected to the inner cavity of the installation box 37 and its open end. In order to further improve the stability of the clamping plate 42, a guide rod 50 is also 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 screw b48 is parallel to the supporting tube 5, and when the bidirectional screw b48 rotates, the two clamping plates 42 thereon approach or move away from each other.

[0038] In specific applications, the push-pull cylinder a2 and the push-pull cylinder d22 can transfer the upper plate 21 horizontally and in height. The horizontal transfer is beneficial for the processing ring 36 to enter and exit the supporting tube 5, and the height transfer enables the rolling ball b49 to correspond to different models of processing rings 36, thereby improving the reliability of clamping; the two-way screw a39 is driven by the motor c24 to rotate, and the distance between the two adjustment plates 27 is adjusted, so that the clamping plate 42 is more matched with the processing ring 36; the long shaft gear 17 is driven by the motor b18 to rotate, thereby driving the end gear 38 to rotate, and the cooperation between the long shaft gear 17 and the end gear 38 can adapt to the distance change of the two adjustment plates 27 to ensure continuous meshing transmission; the rotation of the two two-way screws b48 can enable the two sets of clamping plates 42 to clamp the end face of the processing ring 36, which is beneficial for the transfer of the processing ring 36 and the limiting and movement during grinding.

[0039] The above embodiment of the present invention provides a bearing ring grinding processing device, and the working principle is as follows: The processing ring 36 is first brought to the carrier tube 5 by the auxiliary clamping transfer assembly and smoothly sleeved onto the carrier tube 5. After that, the control assembly is activated, and the push-pull cylinder b4 pushes the center rod 45 to move, and drives the multiple fixing plates 40 to expand outwards through the power rod 46, so as to abut and fix the inner ring of the processing ring 36, and ensure that the processing ring 36 is centered and stable on the carrier tube 5.

[0040] The motor a6 in the driving assembly is started, and the speed is adjusted by the transmission 7 to drive the driving shaft 30 to rotate. The gear c29 on the driving shaft 30 meshes with the gear b15 on the grinding shaft 16 to rotate the grinding wheel 14; at the same time, the gear a9 on the driving shaft 30 meshes with the gear d43 on the bearing cylinder 5 to rotate the bearing cylinder 5 in the same direction, thereby achieving the same-direction differential rotation of the grinding wheel 14 and the bearing cylinder 5.

[0041] 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 processing ring 36 to meet different grinding requirements and ensure grinding accuracy. The grinding wheel 14 is close to the outer surface of the processing ring 36 while rotating to perform grinding operations. The auxiliary clamping transfer assembly can continue to provide additional support and stability for the processing ring 36 during the grinding process to ensure the grinding effect.

[0042] After completing the grinding of a group of to-be-processed rings 36, the auxiliary clamping and transferring assembly will remove the ground rings from the carrier tube 5 and prepare the next group of to-be-processed parts to support continuous production.

[0043] In addition, by replacing or adjusting the diameter of the gears (gear a9, gear b15, gear c29, gear d43), the relative rotation speed of the grinding wheel 14 and the carrier cylinder 5 can be changed to meet the efficient grinding requirements of different types of rings 36 to be processed.

[0044] The whole system is designed to improve grinding efficiency and precision and to adapt to various sizes of rings to be processed 36, while ensuring ease of operation.

[0045] The control of each component can be carried out by a PLC controller disclosed in the prior art, and the model and circuit connection of each component are not specifically limited, and can be flexibly set in actual application. For example, the push-pull cylinder a2, the push-pull cylinder b4, the push-pull cylinder c13, the push-pull cylinder d22 and the push-pull cylinder e34 can be hydraulic cylinders or electric telescopic cylinders.

[0046] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
