Description

Technical Field

[0001] The invention relates to the technical field of bearing processing equipment, and in particular to a bearing ring outer surface grinding equipment for bearing processing. Background Art

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. In the prior art, the application with publication number CN111300214A discloses a bearing ring outer surface grinding device for bearing processing and manufacturing. It is proposed that when the outer peripheral surface of the bearing outer ring is ground, the grinding efficiency and grinding quality are relatively unsatisfactory, and different types of bearing rings require different types of equipment for positioning and grinding, which brings inconvenience to actual production. For this reason, corresponding equipment is set up to cooperate in efficiently completing the processing of bearings of different specifications.

[0003] The deficiency of the above-mentioned prior art is that, in the prior device, the inner wall of the bearing ring is tightly pressed by a plurality of arc-shaped pressure blocks, thereby realizing the positioning of the bearing ring. When controlling the rotation feed of the bearing ring to cooperate with the grinding machine for grinding, the bearing ring is also driven to rotate with the help of a plurality of arc-shaped pressure blocks. However, the arc surface curvature of the arc-shaped pressure blocks is fixed, while the inner wall curvatures of different bearing rings are different. Although the positioning work can be completed by adjusting the position of the arc-shaped pressure blocks, due to the different curvatures, the arc-shaped pressure blocks cannot fit tightly on the inner walls of bearing rings of different specifications, and the driving feeding work cannot be completed stably.

[0004] At the same time, after completing the processing work, the staff is required to perform disassembly operations, so that the grinding work cannot be stopped in time, which is not conducive to the progress of the grinding work. In addition, when performing grinding operations on the outer rings of bearings of different specifications, the staff is required to manually adjust the relative position of the grinder, and the positioning work cannot be completed quickly and accurately, which is also inconvenient to use.

[0034] Here, the reciprocating screw 9 is controlled by the driving device 4 to drive the reciprocating wire block 10 to move, and the supporting sleeve 11 is pulled to move, so that the inner support clamping structure on the supporting sleeve 11 can approach the clamping ring 8 while completing the inner support work, and then cooperate with the clamping ring 8 to complete the clamping and fixing work of the bearing ring from the side, so that the bearing ring can stably rotate with the rotating frame 3, ensuring the stability of the rotary feeding work;

[0035] Reference Figure 6 and Figure 7 The inner support clamping structure includes a trapezoidal tube 16 and a reciprocating wire seat 17 which are slidably connected in the support sleeve 11. The trapezoidal tube 16 is connected to the reciprocating wire seat 17, and the reciprocating wire seat 17 is connected to the reciprocating screw 9. The support sleeve 11 is provided with a plurality of inner support clamping components matching the trapezoidal tube 16. The inner support clamping components include a lifting tube 18, an inner support round block 19, a clamping piece 20 and a lifting column 21. The lifting column 21 is slidably connected in the lifting tube 18, and the lifting column 21 and the lifting tube 18 are connected by a spring 22. The inner support round block 19 and the clamping piece 20 are both connected to the lifting tube 18. A lifting port 60 is provided on the support sleeve 11, and the lifting tube 18 is slidably connected in the lifting port 60. A lifting groove 23 is provided on the inner wall of the lifting port 60. A lifting block 24 is slidably connected in the lifting groove 23. The lifting block 24 is connected to the lifting tube 18, and the lifting block 24 and the lifting groove 23 are connected by a lifting spring 25.

[0036] Here, by means of the inclined surface feature of the trapezoidal tube 16, the inner support round block 19 can complete the support, positioning and fixing work of the bearing ring from the inside, and at the same time, by means of the clamping piece 20, the side clamping and fixing work can be completed;

[0037] Reference Figure 8 The control structure includes a threaded sleeve 26 connected to the reciprocating screw 9 and an external tube 27 connected to the driving shaft of the driving device 4. The side wall of the threaded sleeve 26 is provided with a plurality of slots 28 arranged at equal intervals.

The plurality of clamping blocks 32 are respectively connected to the plurality of triangular block 30. The plurality of clamping blocks 32 are connected to the plurality of clamping grooves 31 through a plurality of clamping springs 33.

[0038] The arrangement of the triangular clamp block 30 here enables the outer tube 27 to smoothly drive the threaded sleeve 26 and the reciprocating screw 9 to rotate, thereby completing the internal support and clamping work, so that the rotary feeding work can be carried out stably. At the same time, the inclined surface feature of the triangular clamp block 30 enables the outer tube 27 to rotate relative to the threaded sleeve 26, thereby preventing the rotary feeding work from interfering with the completed support and clamping work.

[0039] Reference Figure 8 and Fig. 9 The inner screw of the threaded sleeve 26 is connected to the inner wall of the outer tube 27, one end of the plurality of slots 28 is fixedly connected with an annular groove 34, the plurality of triangular blocks 30 are respectively slidably connected in the plurality of slots 28, a telescopic slot 35 is provided on the driving shaft of the driving device 4, a telescopic column 36 is slidably connected in the telescopic slot 35, and the telescopic column 36 is connected to the outer tube 27;

[0040] The arrangement here allows the threaded sleeve 26 to be disconnected from the external tube 27, thereby removing the restriction on the threaded sleeve 26 and the reciprocating screw 9, allowing them to be reset and rotated, thereby releasing the clamping support state of the bearing ring, so that the bearing ring can be easily removed;

[0041] Reference Figure 4 , multiple penetration columns 15 are connected to the reciprocating wire block 10 through multiple connecting frames 37, and a through hole 38 is provided on the rotating frame 3. A through tube 39 is slidably connected in each of the multiple through holes 38. The multiple through tubes 39 are slidably connected to multiple through rods 40 through multiple springs 361. The multiple through rods 40 are respectively connected to the multiple connecting frames 37, and the multiple through tubes 39 are all connected to the clamping ring 8;

[0042] The arrangement here allows the clamping ring 8 to be movable. After the clamping work is completed, the bearing ring can be pushed away from the rotating frame 3 during the reset operation, making it easier for the staff to take the material.

[0043] Reference Figure 1 , Figure 2 and Figure 5A plurality of connecting frames 37 are provided with an annular guide rail 41, two reciprocating frames 42 are slidably connected to the annular guide rail 41, three reciprocating guide rails 43 are provided on the frame 1, reciprocating screw rods 59 are provided in the three reciprocating guide rails 43, the grinder 2 is arranged on one of the reciprocating guide rails 43, and positioning members are provided on the other two reciprocating guide rails 43. A base 44 is provided at the lower end of the frame 1, two basic frames 45 are provided on the base 44, ball screws 46 are slidably connected to the two basic frames 45, and ball screws 46 are provided on the two ball screws 46. The two ball screw blocks 47 are rotatably connected to the two basic frames 45. The inner cavities of the two ball screws 46 are slidably connected to spring rods 49 through spring four 48, and the two spring rods 49 are respectively connected to the reciprocating frame 42. The two ball screw blocks 47 are connected to bevel gear one 50, wherein the two reciprocating screw rods 59 are connected to bevel gear two 51, and the two bevel gear twos 51 are respectively meshed with the two bevel gear one 50, and the other reciprocating screw rod 59 is connected to bevel gear three 52, and the reciprocating guide rail 43 is rotatably connected to bevel gear four 53, and bevel gear four 53 is meshed with bevel gear three 52, and bevel gear four 53 and one of the bevel gear one 50 are connected through a transmission connecting rod 54;

[0044] The positioning member can be controlled to move to the outer wall of the bearing ring. The positioning member can be accurately moved to the specified position through the transmission connecting rod 54 and other structures, and then the grinding machine 2 can be matched with the bearing ring to complete the grinding work. The staff no longer needs to manually control and adjust. The reset operation is notified so that the grinding machine 2 can automatically move away from the bearing ring after the grinding is completed, so as to avoid accidents during disassembly.

[0045] Reference Figure 3 and Figure 4 , the inner walls of the plurality of through openings 12 and the plurality of through holes 38 are provided with limiting grooves 55, the plurality of limiting grooves 55 are slidably connected with limiting blocks 56, and the plurality of limiting blocks 56 are respectively connected to the plurality of through sleeves 13 and the plurality of through tubes 39;

[0046] At this time, the setting of the limit structure ensures the integrity of the device and avoids the occurrence of problems such as falling off and separation;

[0047] Reference Figure 1 The positioning member includes a positioning frame 57 connected to the reciprocating guide rail 43, and one end of the positioning frame 57 is rotatably connected to a positioning wheel 58;

[0048] The rotation setting of the positioning wheel 58 ensures that the positioning work is completed smoothly while the positioning wheel 58 does not interfere with the rotation feeding of the bearing ring.

[0049] During the use of the present invention, the bearing ring is firstly sleeved on the supporting sleeve 11 so that the bearing ring falls on a plurality of inner supporting round blocks 19, and then the driving device 4 and the grinder 2 are turned on. At this time, due to the effect of gravity, the bearing ring will fall to a lower place and will not directly contact the grinder 2 to cause accidental grinding problems. The driving device 4 can drive the external tube 27 to rotate when working. Since the clamping block 32 is pushed by the elastic force of the clamping spring 33 to push the triangular clamping block 30 into the bayonet 29, the triangular clamping block 30 can push the threaded sleeve 26 to rotate with the help of its own inclined surface. At this time, the threaded sleeve 26 rotates synchronously with the external tube 27 without relative lateral displacement. The sleeve 26 can drive the reciprocating screw 9 to rotate, and then drive the reciprocating wire block 10 and the reciprocating wire seat 17 to move horizontally. During the movement of the reciprocating wire seat 17, the trapezoidal tube 16 can be driven to slide, and then the inclined surface of the trapezoidal tube 16 can be used to push the lifting column 21 and the lifting tube 18 to overcome the elastic force of the lifting spring 25 to move, so that the inner support round block 19 contacts the inner wall of the bearing ring, and at the same time, the clamping piece 20 moves to the side of the bearing ring. Here, due to the presence of the second spring 22, the lifting column 21 can slide relative to the lifting tube 18, and then the lifting tube 18 can cooperate to complete the internal support work of the bearing rings with different inner diameters, and the support can be kept firm with the help of the elastic force;

[0050] When the reciprocating wire block 10 moves laterally, the connecting frame 37 can drive the through column 15 and the through sleeve 13, and then pull the support sleeve 11. The clamping piece 20 is located on the support sleeve 11, and at this time, it is close to the clamping ring 8 on the rotating frame 3, so that the bearing ring can be clamped from the side smoothly. The clamping here cooperates with the internal support, and the two cooperate to firmly connect the rotating frame 3 and the bearing ring. When the driving shaft of the driving device 4 drives the rotating frame 3 to rotate through the meshing of the driving gear 5, the transmission gear 6 and the gear ring 7, the bearing ring can be made to rotate synchronously with the rotating frame 3, and then cooperate with the grinder 2 to complete the rotation feeding work, and the outer wall of the bearing ring can fully complete the grinding work. The elastic deformation of the spring 14 here allows the through sleeve 13 to move relative to the through column 15. With the help of this displacement, the clamping work can be completed for bearing rings of different widths without interfering with the internal support. At the same time, the clamping is kept firm with the help of elastic force.

[0051] When one of the spring 14 and the spring 22 reaches the limit position, that is, the relative displacement of the lifting tube 18 and the lifting column 21 or the relative displacement of the through sleeve 13 and the through column 15 reaches the limit position, the reciprocating screw 9 can no longer rotate. At this time, the triangular clamping block 30 can be pushed out of the bayonet 29 by means of its own inclined surface. The elastic deformation ability of the clamping spring 33 makes the pushing work free from interference. The cooperation of multiple triangular clamping blocks 30 can make the threaded sleeve 26 rotate relative to the external tube 27, and the threaded sleeve 26 cannot be reversely rotated and reset, so that the rotation feeding work and the clamping work do not interfere with each other, and both can be smoothly maintained;

[0052] Then, when the threaded sleeve 26 and the outer tube 27 rotate relative to each other, since the internal screw of the threaded sleeve 26 is connected to the outer tube 27, the threaded sleeve 26 will be relatively displaced laterally with the outer tube 27 under the action of the threaded connection. The sliding connection between the telescopic groove 35 and the telescopic column 36 makes the displacement free from interference. When the displacement reaches the designated position, the internal screw of the threaded sleeve 26 is separated, and the multiple triangular clamping blocks 30 move to the annular groove 34, and the restriction of the threaded sleeve 26 by the bayonet 29 is lost. The reciprocating screw 9 and other structures connected to the outside of the threaded sleeve 26 can be reset under the action of the above-mentioned spring elastic force, and the bearing ring loses the clamping and fixing state and can be easily removed.

[0053] When the connecting frame 37 pulls the through column 15 to perform the clamping work, the ball screw 46 will be pulled through the reciprocating frame 42, and then the ball screw block 47 will rotate. When the ball screw block 47 rotates, it can drive the bevel gear 1 50 and the meshing bevel gear 2 51 to rotate, and then the positioning frame 57 can be pushed by the reciprocating screw 59 to position the wheel 58 close to the bearing ring. The positioning wheel 58 contacts the bearing ring to complete the positioning work. At this time, although the reciprocating frame 42 continues to move with the reciprocating wire block 10, the positioning work can be maintained due to the setting of the spring four 48 and the spring rod 49. Then, as the reciprocating screw 9 no longer rotates during the above process, It will not affect the positioning work during the grinding process. When the positioning wheel 58 is positioned and moved with the help of structures such as bevel gear 1 50, the bevel gear 4 53 can be rotated synchronously with the bevel gear 1 50 with the help of the transmission connecting rod 54, and then the grinder 2 is moved synchronously with the positioning wheel 58 through structures such as bevel gear 3 52 and reciprocating screw 59, and then accurately moved to the specified position close to the bearing ring. Here, the positioning and fixing work of the grinder 2 is completed with the help of the positioning wheel 58, which is convenient for the staff to perform the grinding work. At the same time, when the above-mentioned resetting work is carried out, the grinder 2 can also be promptly raised away from the bearing ring to avoid accidents during disassembly.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
