Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a grooved barrel shaft roller polishing machine. Background Art

[0002] The drum polisher is a mechanical device used for surface treatment, commonly used for polishing and grinding metal, wood, plastic and other materials. It usually consists of a large rotating drum and a corresponding drive system. The drum is filled with abrasives, and the surface is polished through rotation and friction. When the drum polisher polishes the grooved drum shaft, the grooved drum shaft is installed in the polisher and rotates with the drum. The polishing is achieved through the collision and friction between the abrasive and the grooved drum shaft.

[0003] A polishing machine is disclosed in a patent application document with publication number CN108115540A, comprising: a drum, an abrasive disposed in the drum, and a tray, wherein the tray is used to mount a workpiece to be polished, wherein the drum and the tray rotate in opposite directions, wherein the workpiece to be polished is pivotally connected to the tray, wherein the workpiece to be polished and the tray rotate in the same or opposite directions, wherein the drum is connected to a first driving device for driving the drum to rotate, wherein the workpiece to be polished and the tray are connected to a second driving device for driving both to rotate, wherein the drum, the workpiece to be polished and the tray all rotate around their own axes, wherein the drum and the tray rotate in opposite directions, thereby increasing the relative speed between the workpiece and the abrasive, thereby increasing the grinding speed and improving the polishing efficiency; in addition, the workpiece in the polishing machine can rotate by itself, and during the rotation of the workpiece, each surface of the workpiece can contact the abrasive in the drum, thereby allowing the abrasive to fully rub against and grind the workpiece, thereby improving the polishing efficiency while achieving uniform polishing of each polishing surface of the workpiece, thereby polishing the workpiece faster and more evenly.

[0004] However, the following problems still exist in this scheme: the relative position of the workpiece on the pallet is fixed and cannot be moved relative to the pallet during polishing. The relative speed between the workpiece and the abrasive is increased only by the reverse rotation of the drum and the pallet, and the increase in grinding force is small. In addition, the distribution of the abrasive in different areas of the drum is random. Since the relative position of the workpiece is fixed, each position of the workpiece can only be polished within a limited area. The area with more abrasive is polished faster, and the area with less abrasive is polished slower, resulting in poor uniformity in the polishing of the workpiece, which can easily lead to excessive differences in the polishing time of different areas on the workpiece, affecting the polishing effect. Summary of the invention

[0005] The present invention provides a grooved shaft drum polishing machine, aiming to solve the problem in the related art that the relative speed between the workpiece and the abrasive is increased only by the reverse rotation of the drum and the tray, the increase in grinding force is small, and it is easy to cause excessive differences in polishing time for different areas on the workpiece.

[0046] Abrasive is added to the polishing cylinder 10 and the opening 13 is closed by the insert plate 15. The polishing cylinder 10 is driven by the first motor 24 to rotate in the frame 20 to polish the groove cylinder shaft. When the polishing cylinder 10 rotates, the partition 11 pushes the slide plate 41 to move around the mounting seat 22, so that the connecting rod 42 slides along the guide rail 43. As the connecting rod 42 moves up and down along the mounting seat 22, the slide plate 41 is pushed to slide and rise in the slide groove 111 on the partition 11, and the mounting plate 31 is driven to reciprocate up and down during polishing.
