Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, and more specifically to a multi-barrel mounting and locking structure for a roller of a large-capacity planetary roller polishing machine. Background Art

[0002] Existing centrifugal roller polishing machines all use a simple planetary motion mechanism, which decomposes the rotation of the motor into a process in which the roller loaded with the polishing parts both revolves and rotates in the opposite direction, so that the polishing parts and the abrasives and grinding fluids grind against each other to achieve the purpose of polishing. The axis of the roller coincides with the axis of rotation, and the rotation and revolution are in opposite directions, so that the workpiece and the abrasives in the roller flow in two dimensions, and produce extrusion, friction, collision and other effects under the action of centrifugal pressure to achieve the polishing and grinding of the workpiece surface. However, the existing polishing machines generally have only multiple rollers. Although different types of workpieces can be put into the rollers, after polishing, the workpieces need to be sorted again, which is inconvenient. In addition, the rollers are not easy to disassemble, and it is cumbersome to take and put the workpieces.

[0003] Therefore, it is necessary to propose a multi-barrel mounting locking structure for a large-capacity planetary roller polishing machine drum to solve the above problems. Utility Model Content

The specific mounting method is the prior art and will not be described again. A plurality of round tubes 3 are distributed in a circumferential array on the outer edge of the roller 1, and an opening 5 for mounting a barrel 7 is reserved, that is, a plurality of barrels 7 are installed in the roller 1 at one time through the opening 5, and the end cover of the barrel 7 can be opened to fill the grinding The inner side surface of the circular tube 3 is fixedly connected with an inner baffle 6, and a plurality of depressions for cooperating with the installation of the barrel 7 are arranged on the inner baffle 6, which is in the shape of a petal as a whole. The locking mechanism arranged at the opening 5 squeezes the barrel 7 at the opening 5 so that the barrel 7 squeezes other barrels 7 and all barrels 7 are temporarily fixed in the depression, thereby realizing the fixation of the plurality of barrels 7, wherein the barrels 7 have six rows, and each row is provided with two barrels 7, i.e., there are two columns of barrels 7 in total, and the locking mechanism is arranged accordingly for each column of barrels 7.

[0023] Specifically, the locking mechanism includes an extrusion assembly for extruding the barrel 7 at the opening 5 and a locking assembly for locking the extrusion assembly. The extrusion assembly is hinged on a first mounting plate 8 fixedly connected to the circular tube 3 at one end of the opening 5, and the locking assembly is arranged on a second mounting plate 16 on the circular tube 3 at the other end of the opening 5.

The extrusion block 23 is a rubber pad, which is elastic and has sufficient friction. It is arranged on the side of the extrusion plate 22 facing the barrel 7. The extrusion plate 22 is fixed on the side of the arc-shaped clamping member 9 facing the barrel 7. The extrusion block 23 facilitates the arc-shaped clamping member 9 to clamp the barrel 7 at the opening 5, and realizes temporary fixation of the barrel 7 by mutual extrusion between the barrels 7.

[0025] Specifically, the extrusion compensation mechanism includes an eccentric shaft 10 eccentrically rotatably connected to the middle part of the arc-shaped clamping member 9, a connecting plate 11 rotatably connected to both ends of the eccentric shaft 10, and a connecting shaft 12 rotatably connected to the end of the connecting plate 11 away from the eccentric shaft 10.
