When polishing, a sanding belt with a certain width is often used only for a circle surrounded by a partial width, and when the partial width is worn, the unused part (width) needs to be fully utilized. The general operation process is that the polishing equipment is stopped, the driven wheel is manually lifted to enable the abrasive belt to move up or down around the part arranged on the driving wheel, and the unused (fully used) part of the abrasive belt can be used after the machine is restarted.
Chinese patent CN 211073047U discloses a polishing mechanism suitable for abrasive belt, wherein an auxiliary wheel is connected to a lifting motor and driven by the lifting motor to lift, the lower end of the lifting motor is fixed on a lifting motor base, the upper end of the lifting motor is connected to the auxiliary wheel through a lifting platform, a guide shaft is arranged on the lifting motor base, and the lifting platform is arranged on the guide shaft through a guide bearing. The auxiliary wheel is driven by the lifting motor to axially move up and down, so that the abrasive belt part wound on the driving wheel moves up and down on the outer surface of the driving wheel, and the workpiece to be processed is polished.
The patent solves the defect that the position change operation mode of the abrasive belt of the prior polishing equipment is very complicated and is not beneficial to the full utilization of the abrasive belt.
But be provided with the guiding axle on its lift motor cabinet, the design that the elevating platform wore to establish on the guiding axle through guide bearing is too loaded down with trivial details, simultaneously, the lifter circumference swing range that leads to when the abrasive band auxiliary wheel rotates is too big not good control, influences the stable efficiency of auxiliary wheel.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a lifting mechanism of an auxiliary abrasive belt wheel of a polishing mechanism, which mainly solves the technical problems in the prior art and can solve the problems that the lifting rod in the prior art has large circumferential amplitude in the lifting process and the auxiliary abrasive belt wheel has unstable efficacy.
The technical scheme of the utility model is as follows:
a lifting mechanism of an abrasive belt auxiliary wheel of a polishing mechanism comprises a lifting motor, a lifting motor base and a lifting rod, wherein the lifting motor is arranged on the lifting motor base; a back plate is arranged above the lifting motor base; and a sliding device and a holding mechanism which enables the lifting rod to further reduce the swing amplitude are arranged between the back plate and the lifting rod, and the lifting rod is fixedly connected with the sliding device.
The sliding device comprises a sliding block connected to the lifting rod and a sliding rail arranged on the back plate; the sliding block is in sliding fit with the sliding rail, and the lifting motor is connected with and drives the sliding block.
The holding mechanism comprises a driving device and a holding connecting piece, and the driving device is arranged at the upper end of the back plate.
The driving device is a cylinder or an oil cylinder.
The part of the holding connecting piece corresponding to the lifting rod is a circular arc concave surface matched with the surface of the lifting rod.
The top end of the lifting rod 7 is connected with the auxiliary wheel of the abrasive belt through a bearing.
By the technical scheme, the utility model has the following advantages:
1. when the lifting device is used, the lifting rod is connected to the sliding block, so that the stability of the lifting rod during lifting can be kept.
2. According to the utility model, the holding connecting piece in the holding device is close to and clings to the lifting rod when the lifting rod rises to a set height, and meanwhile, the groove design of the contact surface of the connecting piece and the lifting rod can well surround the lifting rod, so that the swinging amplitude of the lifting rod caused by the rotation of the auxiliary wheel of the abrasive belt is further reduced.
