Detailed Description
The following describes embodiments of the present utility model in further detail with reference to FIGS. 1-7.
According to the first embodiment, the technical scheme is that when the utility model is used, the clamping device can fix the rectifier shell 28 on the workbench 1, and the width of the polishing sand paper 8 arranged on the polishing roller 7 is larger than that of the rectifier shell 28, so that the polishing sand paper 8 can polish a larger area along with one stroke of the transverse reciprocating device along with the movement of the transverse reciprocating device, and the polishing efficiency is greatly improved. The screw rod 4 that clockwise rotation was equipped with can drive mounting bracket 5 downwardly moving, and then adjusts the interval of polishing roller 7 and rectifier shell 28, can adjust polishing roller 7 through screw rod 4 after polishing abrasive paper 8 has the loss, reduces the interval of polishing roller 7 and rectifier shell 28, and then guarantees the contact degree of polishing abrasive paper 8 and rectifier shell 28, guarantees the effect of polishing. Support legs 27 are provided to support the device.
In the second embodiment, based on the first embodiment, the present utility model uses the clamping device to clamp the rectifier shell 28, the rectifier shell 28 is placed between the clamping devices on the workbench 1, the clamping motor 26 on the support plate 18 is started to rotate forward, the clamping motor 26 drives the rotating shaft 20 to rotate forward, the rotating shaft 20 is integrally and coaxially provided with two threaded portions 21 with opposite rotation directions, so that the rotating shaft 20 rotates forward to drive the two clamping blocks 22 to move relatively along the longitudinal rod 19 through the threaded portions 21 thereon, and then the abutting rod 24 on the clamping blocks 22 moves near the side edge of the rectifier until the anti-slip pad 25 on the abutting rod 24 abuts against the side edge of the rectifier shell 28, and the fixing of the rectifier shell 28 is completed at this time, so that the longitudinal channel 23 is provided for facilitating the movement of the clamping blocks 22. Correspondingly, when the clamping motor 26 is started to rotate reversely, the clamping motor 26 of the clamping device drives the rotating shaft 20 to rotate reversely, and the rotating shaft 20 drives the two clamping blocks 22 to move away relatively along the longitudinal axis through the threaded part 21 on the rotating shaft, so that the fixation of the rectifier shell 28 is released.
In the third embodiment, after the rectifier shell 28 is fixed by the clamping device, the polishing motor 9 and the traversing motor 17 of the transverse reciprocating device can be started to polish, the polishing motor 9 is started to drive the polishing roller 7 rotatably mounted on the mounting frame 5 to rotate, and the polishing sand paper 8 on the polishing roller 7 rotates along with the polishing roller to polish the rectifier shell 28.
