DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-Figure 2 The roller assembly installation system includes a mounting plate 1, and two support seats 2 are fixed on the top of the mounting plate 1 by welding or bolting. The two support seats 2 are designed to support and position the subsequent bearing seat 3 and the rotating shaft 4.

[0020] Two bearing seats 3 are arranged inside each support seat 2. The two bearing seats 3 are opposite to each other, and the distance between them is determined according to the length of the rotating shaft 4. A bearing body 15 is installed in each bearing seat 3, and these bearing bodies 15 jointly support and allow the rotating shaft 4 to rotate.

[0021] The rotating shaft 4 passes through the two bearing seats 3 and realizes stable rotation through the bearing body 15. A roller 8 is sleeved on the rotating shaft 4. The roller 8 is a key component for the cold rolling process, and a cold rolling groove 12 with a gradually changing diameter is opened on its surface. This design allows the material to be gradually compressed and shaped during the cold rolling process.

[0022] In order to firmly fix the roller 8 on the rotating shaft 4, a set of limiting mechanisms is designed. The set of limiting mechanisms includes a limiting cover 9, and a convex block 10 is provided on one side of the limiting cover 9. A groove 11 matching the convex block 10 is provided at one end of the roller 8. When the roller 8 is sleeved on the rotating shaft 4, the convex block 10 of the limiting cover 9 can be aligned with the groove 11 of the roller 8, so that the convex block 10 will be stuck in the groove 11, so that the roller 8 can be driven to rotate through the convex block 10 and the groove 11 during the rotation of the rotating shaft 4.

[0023] In addition, a movable cover 13 is also designed. The movable cover 13 is threadedly sleeved on the rotating shaft 4 to limit the position of the roller 8, and at least two fastening bolts 14 are penetrated at one end of the movable cover 13. One end of these fastening bolts 14 is threadedly connected to the roller 8. By tightening these fastening bolts 14, the roller 8 can be further fixed on the rotating shaft 4 to prevent it from moving in the radial direction.

[0024] At the outer end of the bearing seat 3, the end cover 5 is fixedly connected to the bearing seat 3 by a plurality of second bolts 7. The end cover 5 is designed to protect the bearing body 15 from damage by the external environment. At the same time, the end cover 5 is fixedly connected to the support seat 2 by a plurality of first bolts 6 to ensure the stability and firmness of the entire structure.

[0025] Example 2: Reference Figure 1-Figure 10 The roller production grinding equipment is used in the field of roller processing, and includes a workbench 16, and a rotating disk 17 is rotatably provided at the top center of the workbench 16, and the rotating disk 17 is used to support the roller 8 to be processed. A motor is fixedly provided at the bottom of the workbench 16, and the output end of the motor is fixedly connected to the rotating disk 17. When the motor is started, it drives the rotating disk 17 and the roller 8 thereon to rotate together.

[0026] A positioning platform 44 and two positioning pins 43 are fixedly provided on the top of the rotating disk 17. The positioning platform 44 is located at the center and is used to position the roller 8, while the two positioning pins 43 are distributed on both sides of the positioning platform 44 and are used to be inserted into the threaded holes on the roller 8 to ensure the stability of the roller 8 during the processing.

[0027] Two guide rods 18 are fixedly provided on the top of the workbench 16, and a lifting frame 20 is slidably sleeved on the outer wall of the two guide rods 18. An electric push rod 19 is also fixedly provided through the top of the workbench 16, and the output end of the electric push rod 19 is fixedly connected to the lifting frame 20. When the electric push rod 19 is started, it drives the lifting frame 20 to move up and down along the guide rods 18.

[0028] At the bottom of the lifting frame 20, a moving seat 21 is slidably provided, and a first grinding roller 22 is rotatably provided in the moving seat 21. A first motor 31 is fixedly provided at the top of the moving seat 21, and the output end of the first motor 31 is connected to the first grinding roller 22 through a transmission mechanism. The specific structure of this transmission mechanism includes: a worm 28 that is rotatably provided in the moving seat 21, one end of the worm 28 is fixedly connected to the output end of the first motor 31, and a synchronous wheel 29 is fixedly sleeved on the outer wall of the other end of the worm 28 and the rotating shaft of the first grinding roller 22, and the outer walls of the two synchronous wheels 29 are transmission-connected with a synchronous belt 30. When the first motor 31 is started, it will drive the worm 28 to rotate, and then drive the first grinding roller 22 to rotate through the synchronous wheel 29 and the synchronous belt 30.

[0029] At the same time, a sleeve rod 27 is rotatably provided on one side of the inner wall of the movable seat 21, and a reciprocating screw 26 is provided on the inner thread of the sleeve rod 27. The reciprocating screw 26 is fixedly provided in the lifting frame 20. A worm wheel 33 meshing with the worm 28 is fixedly provided on the outer wall of the sleeve rod 27. When the worm 28 rotates, it also drives the sleeve rod 27 to rotate through the worm wheel 33, and then drives the reciprocating screw 26 to reciprocate in the sleeve rod 27 through the threaded engagement, and finally drives the movable seat 21 and the first grinding roller 22 to reciprocate.

[0030] Next is the design of the grinding assembly. Two sliding blocks 23 are slidably provided on the top of the workbench 16, and a sliding frame 25 is slidably provided inside the two sliding blocks 23. A second grinding roller 34 is rotatably provided through the inner wall of the sliding frame 25, and a second motor 35 is fixedly provided on one side of the sliding frame 25, and the output end of the second motor 35 is fixedly connected to the second grinding roller 34. The two second grinding rollers 34 are relatively set and used to grind the cold rolling groove 12 on the rolling roller 8. Two connecting rods 24 are rotatably provided between the sliding block 23 and the lifting frame 20. When the lifting frame 20 is lifted and moved, the two sliding blocks 23 and the sliding frame 25 are driven to approach or move away from the rolling roller 8 through the connecting rods 24.

[0031] In order to drive the second grinding roller 34 to move, a toothed ring 41 is fixedly sleeved on the outer wall of the rotating disk 17, and a rack 36 meshing with the toothed ring 41 is fixedly sleeved on the inner side of one of the sliding frames 25. At the same time, two limit bars 45 are fixedly sleeved on the top of the workbench 16, and a socket 46 for use with the limit bars 45 is opened on one side of the sliding frame 25. In this way, when the sliding frame 25 moves, the rack 36 will mesh with the toothed ring 41, and the socket 46 will be disengaged from the limit bar 45. On the contrary, the rack 36 will be disengaged from the toothed ring 41, and the limit bar 45 will be inserted into the socket 46, ensuring that the moving trajectory of the sliding frame 25 is accurate and stable. In addition, two sliding rods 47 are fixedly sleeved on one side of one of the sliding frames 25, and the other sliding frame 25 is slidably sleeved on the two sliding rods 47, so that the two sliding frames 25 can move forward and backward at the same time, further enhancing the grinding effect.

[0032] Finally, the design of the chamfering assembly is described. A mounting frame 37 is fixedly provided on the top of the sliding block 23, and a knife handle 38 is slidably provided on the top of the mounting frame 37. A scraper 40 for chamfering the inner wall of the roller 8 is fixedly provided at the bottom of the knife handle 38. A spring 39 is sleeved on the outer wall of the knife handle 38, and the two ends of the spring 39 are respectively fixedly connected to the outer wall of the knife handle 38 and the top of the mounting frame 37, providing a reset power for the knife handle 38. The top of the knife handle 38 is connected to the rotating shaft of the first grinding roller 22. Specifically, a cam 32 used in conjunction with the two knife handles 38 is fixedly sleeved on the rotating shaft of the first grinding roller 22. When the first grinding roller 22 rotates, the cam 32 will drive the two knife handles 38 to move downward respectively, and then drive the scraper 40 to chamfer the inner wall of the roller 8. When the cam 32 rotates in the opposite direction, the spring 39 will drive the knife handle 38 and the scraper 40 to reset, and drive the other knife handle 38 to move downward.

[0033] In addition, in order to protect the gear ring 41 from damage, a protective ring 42 is rotatably sleeved on the outer wall of the rotating disk 17 and is located above the gear ring 41 . The bottom of the protective ring 42 is fixedly connected to the workbench 16 .

[0034] The method for using the roller production grinding equipment comprises the following steps; S1. First, place the roller 8 on the rotating disk 17, then start the electric push rod 19 to drive the first grinding roller 22 to move downward, and at the same time start the first motor 31 to drive the first grinding roller 22 to move back and forth to grind the groove 11 on the roller 8; S2, after the grinding is completed, the electric push rod 19 is started to drive the first grinding roller 22 to move upward, and the two second grinding rollers 34 are driven to approach the roller 8, and at the same time, the second motor 35 is started to drive the second grinding rollers 34 to rotate to grind the cold rolling groove 12 on the roller 8, and during the grinding process, the motor under the workbench 16 is started to drive the roller 8 to rotate and the second grinding rollers 34 to move until the grinding of the cold rolling groove 12 is completed; S3, while the second grinding roller 34 moves, it can drive the scraper 40 to move to the top of the roller 8, and then start the first motor 31 to drive the cam 32 to rotate, which can drive the scraper 40 to contact the inner wall of the top of the roller 8. At this time, the roller 8 rotates to cooperate with the scraper 40 for chamfering; S4. After the processing is completed, the electric push rod 19 is started to retract and drive the two second grinding rollers 34 away from the roller 8, and then the upper and lower materials are ground in sequence.

[0035] In this embodiment, first, the roller 8 is placed on the rotating disk 17, and then the electric push rod 19 is started to drive the lifting frame 20 to move downward. The lifting frame 20 moves downward and can drive the first grinding roller 22 to move downward through the moving seat 21. At the same time, the first motor 31 is started to drive the worm 28 to rotate. During the rotation of the worm 28, the worm wheel 33 can be driven to rotate. The rotation of the worm wheel 33 can drive the sleeve rod 27 to rotate on the reciprocating screw 26. Due to the threaded connection, the sleeve rod 27 can move on the reciprocating screw 26 and drive the first grinding roller 22 to reciprocate. During the rotation of the worm 28, the first grinding roller 22 can also be driven to rotate through the synchronous wheel 29 and the synchronous belt 30. While moving downward, the groove 11 on the roller 8 can be polished by reciprocating movement. After the grinding is completed, the cam 32 is horizontal, and the electric push rod 19 is started to drive the lifting frame 20 to move upward. The upward movement of the lifting frame 20 can drive the first grinding roller 22 to move upward, and at the same time, the two sets of connecting rods 24 can drive the sliding blocks 23 on both sides to approach each other, and can drive the two sliding frames 25 to approach each other, thereby driving the two second grinding rollers 34 to approach the roller 8, and at the same time, the second motor 35 is started to drive the second grinding rollers 34 to rotate to grind the cold rolling groove 12 on the roller 8, until the two second grinding rollers 34 move into place, the rack 36 is meshed with the gear ring 41, and the socket 46 is disengaged from the limit strip 45, and then the workbench 16 is started. The motor at the bottom drives the rotating disk 17 to rotate. During the rotation of the rotating disk 17, the roller 8 can be driven to rotate through the two positioning pins 43. While the rotating disk 17 rotates, the rack 36 can be driven to move through the gear ring 41. The movement of the rack 36 can drive the sliding frame 25 to move. The movement of the sliding frame 25 on one side can drive the other sliding frame 25 to move through the two sliding rods 47. The movement of the sliding frame 25 can drive the second grinding roller 34 to move, so that the gradual cold rolling groove 12 can be ground. When the second grinding roller 34 moves into place, the motor at the bottom of the workbench 16 is started to rotate in the reverse direction to continue reverse grinding until the grinding of the cold rolling groove 12 is completed. During the movement of the sliding block 23, the knife handle 38 can be driven to move through the mounting frame 37 until the knife handle 38 moves to the top of the roller 8. At this time, the top ends of the two knife handles 38 move to the bottom of the cam 32, and then the first motor 31 is started to drive the cam 32 to rotate, which can drive the scraper 40 to contact the inner wall of the top end of the roller 8. At this time, the rotation of the roller 8 can cooperate with the scraper 40 to chamfer. During the reverse rotation of the roller 8, the first motor 31 is started to rotate in the reverse direction, driving the cam 32 to rotate in the reverse direction to make the other scraper 40 contact the roller 8, so as to chamfer the other half of the roller 8. After the processing is completed, the electric push rod 19 is started to retract and drive the two second grinding rollers 34 away from the roller 8, and then the loading and unloading grinding is carried out in sequence.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric push rod 19, the first motor 31 and the second motor 35 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.
