Abstract

The invention specifically refers to a universal rotating mechanism of a stone surface renovation machine. The lower part of the frame gearbox is fixed with a shaft seat, which is sleeved on the planetary shaft, and a cutout is processed on the shaft seat. A floating ball mechanism and an upper arc tray are sequentially installed on the bottom of the planetary shaft from top to bottom. And the planetary disc of the gearbox, the floating ball mechanism includes an inner ring, floating balls, cage and outer ring, and a pit for the floating ball is provided on the side wall of the inner ring, and the inner ring is fixed on the planetary shaft. The outer ring is fixed on the planetary disk of the gearbox and is connected with the transmission gear set through bearings. A fixed seat is fixed on the upper part of the outer ring. There is a movable gap between the fixed seat and the planetary shaft. On the planetary disk of the gearbox A lower arc tray matched with the upper arc tray is provided, and a blocking piece matched with the notch on the shaft seat is arranged above the fixed seat. After adopting the technical solution, the entire planetary disc of the gear box can be properly floated according to the condition of the floor, effectively reducing the grinding resistance and reducing the wear of the grinding head.

Description

The Universal Turning Mechanism of the Stone Surface Restoration Machine

Technical field:

The invention relates to the technical field of decoration engineering, in particular to a universal rotating mechanism of a stone surface renovation machine.

Background technique:

At present, more and more ground decorations use stone floors. During the decoration, the floor must be polished and polished. Its planetary disks are all flat-rotating. When encountering uneven floors, they will only grind hard without floating, which will increase the grinding resistance and accelerate the wear of the grinding head.

Invention content:

The object of the present invention is to provide a universal rotation mechanism of a stone surface renovation machine in order to overcome the above-mentioned deficiencies in the prior art.

In order to achieve the above object, the technical solution provided by the present invention is: the universal rotation mechanism of the stone surface renovation machine, including the planetary shaft, the planetary disc of the gearbox, the gear box of the frame, and the transmission gear set placed in the planetary disc. The lower part of the frame gearbox is fixed with a shaft seat, which is sleeved on the planetary shaft, and they are connected by bearings. There are notches processed on the shaft seat, and the floating ball mechanism is sequentially installed on the bottom of the planetary shaft from top to bottom. The upper arc tray and the planetary disc of the gearbox, the floating ball mechanism includes an inner ring, a floating ball, a cage and an outer ring. On the planetary shaft, the outer ring is fixed on the planetary disk of the gearbox and is connected with the transmission gear set through bearings. A fixed seat is fixed on the upper part of the outer ring. There is a movable gap between the fixed seat and the planetary shaft. A lower arc tray matched with the upper arc tray is arranged on the box planetary disk, and a blocking piece matched with the notch on the shaft seat is arranged above the fixed seat.

After adopting the technical solution, the entire planetary disk can be properly floated according to the condition of the floor, effectively reducing the grinding resistance and reducing the wear of the grinding head.

Detailed ways:

As shown in attached drawings 1 to 4, the universal rotation mechanism of this stone surface refurbishment machine includes a planetary shaft 1, a planetary disc 2 in a gear box, a gear box 4 in a frame, and a transmission gear placed in a planetary disc 2 in the gear box. Group 3, a shaft seat 5 is fixed on the lower part of the frame gearbox 4, and the shaft seat 5 is set on the planetary shaft 1, and they are connected by bearings 6, and a notch 7 is processed on the shaft seat 5, and the planetary shaft The bottom of 1 is fitted with a floating ball mechanism, an upper arc tray 8 and a planetary disc 2 of the gearbox in sequence from top to bottom. The floating ball mechanism includes an inner ring 9, a floating ball 10, a cage 11 and an outer ring 12. The inner ring The side wall of 9 is provided with a pit 13 for the floating ball 10 to be moved. The inner ring 9 is fixed on the planetary shaft 1, and the outer ring 12 is fixed on the planetary disc 2 of the gearbox and is connected to the transmission gear set 3 through a bearing. 18 connection, a fixed seat 14 is fixed on the upper part of the outer ring 12, and a movable gap 15 is provided between the fixed seat 14 and the planetary shaft 1, and a lower circle that matches the upper arc tray 8 is provided on the planetary disk 2 of the gear box. The arc tray 16 is provided with a stopper 17 on the top of the fixed seat 14 to cooperate with the notch 7 on the shaft seat 5 .

After the above structure is commonly used, the gear box planetary disc assembly can realize the universal floating function by using the cooperation of the floating ball mechanism and the upper and lower arc trays.
