Technical Field
[0001] This utility model relates to the technical field of roll processing equipment, specifically to an online roll turning device for a CNC roll grinding machine. Background Technology
[0002] An automatic roll turning device is a device used to automatically flip the bearing box of a roll during the processing or maintenance of rolls. During the processing of rolls such as grinding, the shape of the bearing box may cause interference with the grinding wheel head and other components of the grinding machine. The automatic roll turning device can flip the bearing box at a certain angle to avoid interference, while ensuring the stability and accuracy of the roll during the processing. It can also eliminate the trouble of assembling and disassembling the bearing box for roll grinding, thus improving processing efficiency.
[0003] In practical use, arc-shaped guide rails and gears are usually used for transmission to drive the rolls to rotate 90° for adjustment. During the operation of the roll grinding machine, equipment vibration is inevitable. The gear and ring transmission is very sensitive to changes in the center distance between the two shafts. Even a slight change in the center distance may affect the normal meshing of the gears, leading to problems such as reduced transmission efficiency and increased noise. Secondly, the installation, maintenance and repair of gears and racks are complex and costly, and the entire maintenance process is time-consuming, which will affect the normal production of the equipment. In order to solve the above problems, the inventor proposes an online roll turning device for CNC roll grinding machines. Utility Model Content

A drive shaft is fixedly connected to the drive end of the helical gear reducer motor, and the drive shaft and the driven shaft are connected by a chain transmission group.
[0007] Preferably, the automatic lubrication assembly includes a cylinder and a crankshaft. The cylinder is fixedly installed at the bottom of the side frame, and the crankshaft is located above the cylinder and rotatably mounted on the side frame. A connecting rod is rotatably mounted on the protrusion of the crankshaft.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] 1. This utility model, by setting up a rotation adjustment component, enables the driven shaft to drive the sector-shaped arc plate and bearing housing to slide in an arc shape under the guidance of the arc-shaped guide rail and pulley block after secondary deceleration. This achieves the adjustment effect of the rotation of the bearing housing and its rolls during the production process. By adopting roller chain drive, the roller chain drive, with its unique structural characteristics, is minimally affected during the production process and can operate continuously and stably, ensuring the smooth progress of the entire production process, effectively reducing the equipment failure rate, and providing a solid guarantee for the efficiency and stability of production.
[0010] 2. This utility model, by setting up an automatic lubrication component, enables the bearing housing to rotate and adjust automatically without the application of an external drive source, thus achieving the effect of automatic unidirectional delivery of lubricant. This ensures good lubrication at the meshing points of the sprocket and roller chain, greatly reducing the coefficient of friction between components, reducing wear, effectively extending the service life of the equipment, and ensuring the stability and reliability of the equipment operation.

[0024] The automatic lubrication assembly 5 includes a cylinder 51 and a crankshaft 52. The cylinder 51 is fixedly installed at the bottom of the side frame 2.

[0027] By adopting the above technical solution, the sprocket 310 drives the fan-shaped arc plate 32 to slide through the roller chain 34.
[0028] The outer wall of the fan-shaped arc plate 32 is fixedly provided with an arc-shaped guide rail 37. The inner wall of the side frame 2 is provided with three pulley groups 38 that cooperate with the arc-shaped guide rail 37. The top of the machine base 1 is fixedly provided with a guide frame 6 on the side away from the side frame 2. The guide frame 6 is also provided with pulley groups 38, and the arc-shaped guide rail 37 makes rolling contact with each pulley group 38.
[0029] By adopting the above technical solution, the pulley block 38 provides precise guidance for the fan-shaped arc plate 32, enabling it to achieve stable and smooth rotation along a predetermined arc trajectory.
[0030] The drive end of the helical gear reducer motor 7 is fixedly connected to the drive shaft 311, and the drive shaft 311 and the driven shaft 39 are connected by a chain drive assembly.
[0031] By adopting the above technical solution, the drive shaft 311 drives the driven shaft 39 to rotate at a reduced speed through the chain drive assembly.
[0032] The drive shaft 311 is fixedly sleeved with a drive wheel 57 on its outer wall, and the crankshaft 52 is fixedly sleeved with a driven wheel 58 that cooperates with the drive wheel 57, and the drive wheel 57 and the driven wheel 58 are meshed together.
[0033] By adopting the above technical solution, the drive shaft 311 drives the drive wheel 57 to rotate intermittently.
[0034] An oil tank 55 is located directly below the sprocket 310 and is fixedly installed in the side frame 2.

[0038] Working principle: In practical applications of roll production, CNC roll grinding machines are used to grind and shape the rolls. When interference occurs between the bearing housing 4 and components such as the grinding wheel head of the grinding machine, such as... Figure 1 , Figure 2 As shown, the control turns on the helical gear reducer motor 7. The drive end of the helical gear reducer motor 7 drives the drive shaft 311 to rotate in the forward direction. The drive shaft 311 drives the driven shaft 39 to rotate at a reduced speed through the chain transmission group. The driven shaft 39 drives the bearing box 4 and its rollers to rotate stably and smoothly along a predetermined arc trajectory under the action of the arc guide rail 37 and the pulley group 38, so as to achieve the effect of adjusting the rotation angle of the rollers. When it is necessary to reset the driven bearing box 4, it is only necessary to control the helical gear reducer motor 7 to rotate in the reverse direction.
[0039] During the rotation of the drive shaft 311, the crankshaft 52 is driven to rotate intermittently through the drive wheel 57 and the driven wheel 58. One rotation of the drive shaft 311 causes the crankshaft 52 to rotate a quarter circumference. During the rotation of the crankshaft 52, the piston rod 54 is driven to move up and down in the cylinder 51 through the connecting rod 53. When the piston rod 54 moves upward, the pressure inside the cylinder 51 decreases, forcing the lubricant in the oil tank 55 to enter the cylinder 51. When the piston rod 54 moves downward, the pressure drop inside the cylinder 51 increases, forcing the lubricant in the cylinder 51 to be discharged into the oil drain pipe 56, and discharged to the meshing area of the sprocket 310 and the roller chain 34 through the oil drain pipe 56.
