In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
Referring to fig. 1 and 2, fig. 1 is a front view illustrating a structure of an online polishing apparatus according to an embodiment of the present invention; fig. 2 is a top view of the swing assembly of fig. 1.
In a specific embodiment, the online polishing device provided by the invention comprises a bracket 11 and a controller (not shown in the figure) which are arranged at the side part of a cooling roller 21, wherein a main guide rail 111 extending along the axial direction of the cooling roller 21 is arranged on the bracket 11, a feeding assembly 12 is arranged on the main guide rail 111, a feeding guide rail 121 extending along the radial direction of the cooling roller 21 is arranged on the feeding assembly 12, a swinging assembly 13 is arranged on the feeding guide rail 121, the swinging assembly 13 comprises a shaft seat 131 capable of swinging in a fixed shaft and a polishing wheel 132 which is linked with the shaft seat 131 and can rotate in a fixed shaft way, and the axial direction of the shaft seat 131 and the radial direction of the polishing wheel 132 are consistent with the radial direction of the cooling roller 21; the bracket 11 is provided with a main driving device 112 capable of driving the feeding assembly 12 to reciprocate along the main guide rail 111, and the feeding assembly 12 is provided with a feeding driving device (not shown) capable of driving the swinging assembly 13 to reciprocate along the feeding guide rail 121.
In the running process of the equipment, the feeding assembly 12 and the swinging assembly 13 are driven by the main driving device 112 to axially move to corresponding stations matched with the cooling roller 21 along the cooling roller 21, then the swinging assembly 13 is driven by the feeding driving device to radially move to a proper position along the cooling roller 21 so as to enable the polishing wheel 132 to be in contact with the outer peripheral surface of the cooling roller 21, then the corresponding contact position of the outer peripheral surface of the cooling roller 21 is polished by utilizing the rotation of the polishing wheel 132, and meanwhile, the polishing wheel 132 is driven by the reciprocating swing of the shaft seat 131 to correspondingly reciprocate around the radial direction of the cooling roller 21, so that the contact angle between the polishing wheel 132 and the cooling roller 21 and the polishing working surface range are changed (the actual working surface position of the polishing wheel 132 can refer to 211 in fig. 1), thereby the polishing uniformity and polishing efficiency are effectively improved, defects such as pits or lines on the surface of the cooling roller 21 caused by fixed working surface polishing are effectively avoided, corresponding defects of products caused by the surface defects of the cooling roller 21 are avoided, and the quality of products is ensured.
It should be noted that, in particular, in practical application, in order to realize high-precision polishing operation to ensure polishing effect, the pivot angle value of the shaft seat can be determined according to process requirements, corresponding parameter information is input into the controller, and then control signals are transmitted to each driving device and each actuating mechanism by the controller according to the preset parameters so as to control the final polishing operation effect.
Further, the reciprocating swing angle of the shaft seat 131 is within ±50°. The swing angle range can meet the basic polishing operation requirement, but in the actual operation process, the staff can flexibly adjust the swing angle range of the shaft seat 131 according to the working condition requirement, and in principle, the swing angle range can meet the actual use requirement of the online polishing device.
Furthermore, after the actual polishing work is completed, the effect is generally achieved that the outer peripheral surface of the cooling roller 21 has a finish ra=0.05 to 0.4, and in principle, the operator can adjust the final finish value according to the actual need, but should be able to meet the actual work demand of the cooling roller 21 in principle.
More specifically, the swinging assembly 13 further includes a swinging driving device 133 that can drive the shaft seat 131 to swing reciprocally, and a polishing driving device 134 that can drive the polishing wheel 132 to spin on its fixed shaft. In the polishing operation, the swing driving device 133 cooperates with the polishing driving device 134 to enable the end polishing operation surface of the polishing wheel 132 to meet the polishing requirement of the cooling roller 21.
The swing drive device 133 and the polishing drive device 134 are each one of a motor drive mechanism, a rack and pinion mechanism, and a worm and gear mechanism.
