[0027] See also Figure 1-4 The utility model provides a technical solution: a clamping device for polishing wooden furniture, comprising:

[0028] The equipment body 1 has a panel 2 fixedly mounted on the surface of the equipment body 1;

[0029] A polishing assembly is arranged on the top of one end of the equipment body 1, and the polishing assembly moves along one end of the equipment body 1 to the other end at the top of the equipment body 1, so as to evenly polish the wood;

[0031] A clamping assembly is arranged at the other end of the equipment body 1, and the clamping assembly is used to clamp wood of different shapes. The clamping assembly includes two first drive shafts 18 rotatably connected to the top of one end of the equipment body 1 and the top of the second movable seat 17 through bearings, one of the first drive shafts 18 is driven by a servo motor, and a clamping tube 19 is fixedly installed at one end of the opposite surface of the two first drive shafts 18, and the inner wall of the clamping tube 19 is a conical structure. The surface of the first drive shaft 18 is rotatably connected to a movable arm 20 through a bearing, and a movable groove 21 is opened in the middle of the movable arm 20.

A first screw rod 23 is rotatably connected, and the first screw rod 23 is threadedly connected to the middle part of the slider 22. The slider 22 is an I-shaped structure, and the size of the middle part of the slider 22 is adapted to the size of the movable groove 21. One end of the slider 22 corresponding to the position of the clamping tube 19 is rotatably connected to two squeezing rollers 24 through a bearing, and the center of the two squeezing rollers 24 forms an isosceles triangle structure with the circle of the clamping tube 19. The surfaces of the squeezing rollers 24 and the clamping tube 19 are respectively roughened. A worm gear groove is provided on the surface of one end of the movable arm 20, and a worm gear 25 is meshed on the surface of the worm gear groove. A positioning frame 26 is rotatably connected to the surface of the worm gear 25 through a bearing, and the positioning frame 26 is fixedly mounted on the top of the device body 1.

[0032] When the above structure is in use, the two ends of the cylindrical wood are placed in the middle position of the two clamping tubes 19. At this time, the second movable seat 17 is driven by the hydraulic rod to move, and the second movable seat 17 drives one of the clamping tubes 19 to move toward one end of the other clamping tube 19 until the two clamping tubes 19 clamp the cylindrical wood. Since the inner wall of the clamping tube 19 is a conical structure, the clamping tube 19 can clamp cylindrical wood of various sizes.

[0033] When it is necessary to clamp the board-shaped wood, the distance between the squeezing roller 24 and the clamping tube 19 is adjusted to match the thickness of the board-shaped wood. At this time, the board-shaped wood is placed between the two squeezing rollers 24 and the clamping tube 19, and the two squeezing rollers 24 cooperate with the clamping tube 19 to clamp the board-shaped wood. The first driving shaft 18 is driven to rotate by the servo motor, and the first driving shaft 18 drives the clamping tube 19 to rotate, so as to transport the board-shaped wood, so that the board-shaped wood is evenly polished under the operation of the polishing assembly.

[0034] The polishing assembly includes a first movable seat 3, which is movably arranged on the top of the equipment main body 1. One end of the first movable seat 3 is fixedly installed with a mounting cover 4, and both ends of the mounting cover 4 are respectively rotatably connected with a driving roller 5 and a transmission roller 6 through bearings. The surfaces of the driving roller 5 and the transmission roller 6 are respectively传动连接 with a polishing belt 7, so that when the polishing belt 7 is传动, it will polish the wood attached to its surface. A driving motor 13 is fixedly installed on the top of the first movable seat 3. The surfaces of the output shaft of the driving motor 13 and one end of the central shaft of the driving roller 5 are respectively fixedly installed with a first transmission wheel 14, and the surfaces of the two first transmission wheels 14 are respectively传动连接 with a first transmission belt 15. One end of the mounting cover 4 corresponding to the middle position of the polishing belt 7 is fixedly installed with a fixed seat 8. A plurality of adjusting frames 9 are movably inserted in the middle of the fixed seat 8. The adjusting frame 9 is in a U-shaped structure. The bottom of the adjusting frame 9 is rotatably connected with an adjusting roller 10, and the adjusting roller 10 is rotatably connected with the inner wall of the polishing belt 7. A positioning rod 11 is fixedly installed on the inner wall of the adjusting frame 9, and the positioning rod 11 movably penetrates and extends to both ends of the fixed seat 8. An adjusting spring 12 is fixedly installed at the bottom of the adjusting frame 9 corresponding to the position of the positioning rod 11, and the adjusting spring 12 is fixedly installed on the top of the fixed seat 8.

[0035] When the above structure is in use, the driving motor 13 is powered on to drive the first transmission wheel 14 to rotate, and the first transmission wheel 14 cooperates with the first transmission belt 15 to drive the driving roller 5 to rotate. Then, the polishing belt 7 is传动 on the surfaces of the driving roller 5, the transmission roller 6 and the adjusting roller 10, and polishes the wood attached to the surface of the polishing belt 7. During the attachment process, the polishing belt 7 will drive the adjusting roller 10 and the adjusting frame 9 to move upward, and stretch the adjusting spring 12 through the adjusting frame 9, so that the polishing belt 7 can be adaptively adjusted according to the shape of the wood.

[0036] Two movable frames 28 are movably arranged on the top of the equipment main body 1 corresponding to the position of the first movable seat 3, and tracks are fixedly installed on the tops of the two movable frames 28. The bottom of the first movable seat 3 corresponding to the tracks is rotatably connected with track rollers, so that the first movable seat 3 moves along one end of the track to the other end through the track rollers. Both ends of the opposite surfaces of the two movable frames 28 are respectively rotatably connected with a second driving shaft 29 through a support seat, and a second transmission wheel 30 is fixedly installed on the surface of the second driving shaft 29. The surfaces of the two second transmission wheels 30 are传动连接 with a second transmission belt 31, and the middle of the second transmission belt 31 is fixedly installed with the bottom of the first movable seat 3. One end of the equipment main body 1 corresponding to the position of the first driving shaft 18 is fixedly installed with a positive and negative motor 16. One end of the output shaft of the positive and negative motor 16 is fixedly installed with a second lead screw 33, and the second lead screw 33 is threadedly connected with the middle of the movable frame 28. Guide rods 32 are movably inserted at both ends of the bottom of the movable frame 28, and the guide rods 32 are fixedly installed on the top of the equipment main body 1.

[0037] When the above structure is in use, the forward and reverse motors 16 cooperate with the second screw 33 to drive the movable frame 28 to move, thereby changing the distance between the movable frame 28 and the cylindrical wood, that is, changing the pressure between the polishing belt 7 and the cylindrical wood, thereby adjusting the polishing force of the cylindrical wood. At the same time, by rotating the worm gear 25, the worm gear 25 drives the movable arm 20 to rotate, that is, the movable arm 20 drives the squeezing roller 24 to rotate through the slider 22, and adjusts the inclination angle of the plate-shaped wood between the two squeezing rollers 24 and the clamping tube 19, that is, changing the pressure between the polishing belt 7 and the plate-shaped wood to adjust the polishing force of the plate-shaped wood.

[0038] The working principle corresponding to the above structure is: when in use, the utility model places the two ends of the cylindrical wood in the middle position of the two clamping tubes 19 when clamping the cylindrical wood. At this time, the hydraulic rod drives the second movable seat 17 to move, and the second movable seat 17 drives one of the clamping tubes 19 to move toward one end of the other clamping tube 19 until the two clamping tubes 19 clamp the cylindrical wood. Since the inner wall of the clamping tube 19 is a conical structure, the clamping tube 19 can clamp cylindrical wood of various sizes.

[0039] When it is necessary to clamp the plate-shaped wood, the first screw rod 23 is rotated at this time, and the first screw rod 23 drives the slider 22 to move on the inner wall of the movable groove 21, thereby changing the distance between the squeezing roller 24 and the clamping tube 19, so that the distance between the squeezing roller 24 and the clamping tube 19 is adapted to the thickness of the plate-shaped wood. At this time, the plate-shaped wood is placed between the two squeezing rollers 24 and the clamping tube 19, and the two squeezing rollers 24 cooperate with the clamping tube 19 to clamp the plate-shaped wood. At this time, the first driving shaft 18 is driven to rotate by the servo motor, and the first driving shaft 18 drives the clamping tube 19 to rotate, so as to transport the plate-shaped wood, so that the plate-shaped wood is evenly polished under the operation of the polishing assembly.

[0040] When cylindrical wood and plate-shaped wood need to be polished, the second screw rod 33 is driven to rotate by the forward and reverse motor 16, and the second screw rod 33 drives the movable frame 28 to move toward the wood under the guidance of the guide rod 32 until the polishing belt 7 fits the surface of the wood.

[0041] There are two states in which the polishing belt 7 is fitted with the wood surface. The first state is cylindrical wood, in which the polishing belt 7 is wrapped and fitted with the cylindrical wood. The other state is that the polishing belt 7 is flat and fitted with the plate-shaped wood. During the fitting process, the polishing belt 7 drives the adjusting roller 10 and the adjusting frame 9 to move upward, and the adjusting spring 12 is stretched by the adjusting frame 9, so that the polishing belt 7 can be adaptively adjusted according to the shape of the wood. At the same time, by setting the adjusting spring 12, when the wood is separated from the polishing belt 7, the adjusting roller 10 returns to the initial state.

[0042] When the polishing belt 7 is in contact with the wood, the driving motor 13 is energized to drive the first transmission wheel 14 to rotate, and the first transmission wheel 14 cooperates with the first transmission belt 15 to drive the driving roller 5 to rotate, so that the polishing belt 7 is transmitted on the surface of the driving roller 5, the transmission roller 6 and the adjusting roller 10, and the wood in contact with the surface of the polishing belt 7 is polished.

[0043] When it is necessary to adjust the polishing force of the plate-shaped wood, the worm gear 25 can be rotated to drive the movable arm 20 to rotate, that is, the movable arm 20 drives the squeezing roller 24 to rotate through the slider 22, and adjusts the inclination angle of the plate-shaped wood between the two squeezing rollers 24 and the clamping tube 19, that is, changes the pressure between the polishing belt 7 and the plate-shaped wood to achieve the adjustment of the polishing force of the plate-shaped wood, and when it is necessary to adjust the polishing force of the cylindrical wood, the forward and reverse motors 16 cooperate with the second screw 33 to drive the movable frame 28 to move, change the distance between the movable frame 28 and the cylindrical wood, that is, change the pressure between the polishing belt 7 and the cylindrical wood, thereby achieving the adjustment of the polishing force of the cylindrical wood.
