The purpose of this utility model is to provide an abrasive belt grinder for the external polishing of annular workpieces in view of the above-mentioned problems. The clamping device can clamp annular workpieces of different specifications, the clamping is stable and reliable, and only one set of drive system is needed to realize the workpiece Simultaneously driven with the abrasive belt machine, low investment cost and good energy saving effect. the

Above-mentioned purpose realizes by following technical scheme:

A belt grinder for external polishing of annular workpieces, including a driving motor, the driving motor is connected to the driving gear through a reducer, the driving gear is meshed with the driven gear, and the shaft of the driving gear is evenly distributed and installed in the axial direction A set of cylinder bases, each cylinder base is equipped with a cylinder, the piston rod end of the cylinder is equipped with a top block, the top block is fitted with a workpiece, and the shaft of the driven gear is equipped with an abrasive belt The abrasive belt is installed on the abrasive belt wheel to bypass the workpiece, and a tensioning wheel is also arranged between the driving gear and the driven gear. the

In the abrasive belt grinder for external polishing of the annular workpiece, the transmission ratio of the driving gear and the abrasive belt wheel must not be equal to 1. the

The abrasive belt grinder for external polishing of the annular workpiece also includes a mounting plate, the driving gear and the driven gear are mounted on the back side of the mounting plate, and the cylinder seat, abrasive belt wheel, and tensioning wheel are mounted on the On the face side of the plate, the shaft of the driving gear and the shaft of the driven gear pass through the mounting plate. the

In the abrasive belt grinder for external polishing of the annular workpiece, a tensioning wheel track is arranged on the mounting plate, and a spring seat is arranged inside the tensioning wheel track, and one end of the spring is installed in the spring seat, and the other end Connect the top block two, the axle of the tension wheel is installed in the inside of the tension wheel track and is compressed by the top block two. the

In the abrasive belt grinder for external polishing of the annular workpiece, a friction pad is arranged between the top block 1 and the workpiece. the

In the abrasive belt grinder for external polishing of the annular workpiece, there are 3-8 cylinder seats. the

Beneficial effect:

1. The utility model adopts a set of driving device, the active gear drives the workpiece to rotate, and the passive gear drives the abrasive belt to move, thus realizing the relative frictional movement between the abrasive belt and the workpiece, so that only one set of driving system is needed to realize the workpiece and the abrasive belt. Simultaneous drive with the machine, low investment cost and good energy saving effect. At the same time, the utility model adopts a group of cylinders to evenly tighten the workpiece from the inside to the outside, and the clamping is stable. At the same time, the elongation of the cylinder can be adjusted according to the size of the inner diameter of different workpieces, which is convenient for clamping workpieces of different sizes, and has strong versatility. Wide range of applications. the

2. Since when the transmission ratio of the driving gear and the passive gear is equal to 1:1, the linear speed of the workpiece and the abrasive belt will be equal, resulting in slippage, and the effect of polishing and grinding cannot be achieved. Therefore, the utility model has been precisely designed. It is found through calculation and experimental verification that the transmission ratio of the driving gear and the abrasive belt wheel must not be equal to 1. the

3. The utility model is equipped with a tensioning wheel, which not only makes the installation of the abrasive belt more convenient, but also overcomes the deformation margin generated during the working process of the abrasive belt, making the abrasive belt work more reliable. the
