[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 4As shown, this utility model embodiment provides a surface polishing device for bamboo and wood products, including a frame 1, a moving mechanism 2, a moving frame 3, a lifting mechanism 4, a mounting arm 5, a swing arm 61, a swing push rod 62, a grinding wheel 7, a rotating mechanism 8, and a lifting and rotating clamp 9.

The moving mechanism 2 is used to drive the moving frame 3 to move horizontally along the frame 1. The mounting arm 5 is movably connected to the moving frame 3 through a first rotating shaft 51. The lifting mechanism 4... The movable end of the lifting mechanism 4 is hinged to the bottom of the mounting arm 5 and is mounted on the movable frame 3. The lifting mechanism 4 is used to drive the mounting arm 5 to swing up and down around the first rotating shaft 51. The swing arm 61 is movably connected to the mounting arm 5. The push rod of the swing arm 61 is mounted on the mounting arm 5 and its movable end is connected to the swing arm 61.

The rotating mechanism 8 is mounted on the mounting arm 5 and is connected to the grinding wheel 7 through a transmission to drive the grinding wheel 7 to perform rotary polishing on the bowl-shaped bamboo and wood products in the lifting and rotating clamp 9. The lifting and rotating clamp 9 is used to stably clamp the bowl-shaped bamboo and wood products, and adjusts the workpiece to a suitable polishing position through its lifting function. At the same time, it uses the rotation function to rotate the workpiece, thereby polishing different positions of the workpiece. The moving mechanism 2 can drive the moving frame 3 to move along the horizontal direction of the frame 1, so that the grinding wheel 7 can perform polishing operations on both sides of the workpiece. Through the action of the lifting mechanism 4, the mounting arm 5 can swing up and down around the first rotating axis 51 to adjust the height and angle of the grinding wheel 7 so that it fits the surface of the bamboo and wood products in different parts. The swing push rod 62 can drive the swing arm 61 to swing flexibly, so that the grinding wheel 7 can better adapt to the processing requirements of complex shapes on the surface of the workpiece. The rotating mechanism 8 can drive the grinding wheel 7 to rotate at high speed, so that the grinding wheel 7 can achieve stable polishing.

[0036] like Figure 4As shown, the lifting and rotating clamp 9 further includes a clamping plate 91, a lifting cylinder 92, a connecting shaft 93, a rotating bushing 94, a rotating assembly 95, and a limiting pressure plate 96. The clamping plate 91 has multiple supporting blocks 911 along its circumference.

The first driving pulley 952 and the first driven pulley 953 are connected by the first transmission belt. When the first motor 951 is started, it can drive the chuck 91 to rotate through the rotating bushing 94, thereby rotating the position of the bowl-shaped bamboo and wood product to meet the needs of the polishing operation.

[0038] like Figure 4 As shown, the supporting inclined surface 912 is further provided with a flexible pressure strip 913. The flexible pressure strip 913 is made of polyurethane material, which has the characteristics of soft material, and can provide a certain buffering effect when the bowl-shaped bamboo and wood products come into contact with the outer wall of the support block 911, so as to avoid surface indentation or scratches caused by rigid contact.

When the second motor 81 is started, the bidirectional pulley 83 can be driven to rotate through the cooperation of the second driving pulley 82 and the second transmission belt. The rotating bidirectional pulley 83 can then drive the second driven pulley 84 to rotate via the third transmission belt, thereby achieving high-speed rotation of the grinding wheel 7.

[0041] like Figure 3 As shown, the moving mechanism 2 further includes a third motor 21, a lead screw 22, a threaded seat 23, a slide rail 24, and a slider 25. The two slide rails 24 are respectively located on both sides of the frame 1. The bottom of the moving frame 3 is movably connected to the slide rails 24 via the slider 25. The third motor 21 is located on the frame 1, and the output shaft of the third motor 21 is connected to the lead screw 22. The third motor 21 is used to drive the lead screw 22 to rotate. The threaded seat 23 is sleeved on the lead screw 22 and connected to the bottom of the moving frame 3. The threaded seat 23 is used to push the moving frame 3 to move along the extension direction of the slide rail 24 as the lead screw 22 rotates, thereby realizing the back-and-forth movement of the grinding wheel 7, so that the grinding wheel 7 polishes specific parts of the workpiece.
