A gear 116 meshing with the first rack 1141 and the second rack 1151 is rotatably connected to the center position of the upper surface of the workbench 100. By driving the gear 116 to rotate through the movement of the first clamping plate 114 in cooperation with the first rack 1141, power is provided for the second rack 1151 through the gear 116, so that the second clamping plate 115 is driven to move through the second rack 1151, facilitating the first clamping plate 114 and the second clamping plate 115 to move closer to the middle simultaneously, facilitating the clamping and fixing of furniture, and facilitating subsequent grinding of the furniture;

[0036] Exemplarily, a through groove is formed on the surface of the workbench 100. A connecting block 1142 sleeved on the inner wall of the through groove is fixedly connected to the lower surface of the first clamping plate 114. The connecting block 1142 is fixedly connected to the telescopic rod 1131. The first clamping plate 114 is driven to move through the telescopic rod 1131 in cooperation with the connecting block 1142, providing power for the first clamping plate 114, and facilitating the clamping of furniture in cooperation with the second clamping plate 115;

[0037] Exemplarily, the grinding assembly 120 includes a fixed frame 121 located above the workbench 100. A second motor 122 is fixedly installed at one end of the fixed frame 121.

The second threaded rod is installed and used through the fixed frame 121. The second motor 122 is started, and the second threaded rod is driven to rotate through the second motor 122. The second air cylinder 123 is driven to move on the outer wall of the second threaded rod through the acting force of the second threaded rod, facilitating the adjustment of the position of the grinding wheel 1242 on the second air cylinder 123, and facilitating the multi-directional grinding of furniture, with high flexibility;

[0038] Exemplarily, a third motor 124 is fixedly connected to the bottom end of the second air cylinder 123. The output end of the third motor 124 is connected to a grinding wheel 1242 through a coupling. The grinding wheel 1242 is driven to rotate through the use of the third motor 124, and the furniture is ground and processed through the grinding wheel 1242;

[0039] Exemplarily, a connecting sleeve 1241 is fixedly connected to the bottom end of the third motor 124 and sleeved on the outer wall of the top end of the grinding wheel 1242. A sleeve block 125 is fixedly connected to the bottom end of the connecting sleeve 1241. The outer wall of the sleeve block 125 is movably sleeved with a dust suction hood 126. The dust suction hood 126 is installed by using the mutual cooperation of the connecting sleeve 1241 and the sleeve block 125. The dust suction hood 126 adsorbs and collects the debris and dust generated when the grinding wheel 1242 grinds the furniture, preventing the debris and dust from damaging the physical health of the staff.

[0040] In some examples, refer to Figure 1 、 Figure 2 、 Figure 4 The lower surface of the workbench 100 is symmetrically and fixedly connected with multiple groups of first support columns 110, and the multiple groups of first support columns 110 are used to support the workbench 100.

[0041] Exemplarily, a limiting plate 111 is fixedly connected to the upper surface of the rear side of the workbench 100, and a placement plate 1121 located above the gear 116 is fixedly connected to the upper surface of the workbench 100. When furniture needs to be processed, first place the furniture on the upper surface of the placement plate 1121, and position the furniture by abutting one end of the furniture against the limiting plate 111, facilitating the subsequent clamping of the furniture by the first clamping plate 114 and the second clamping plate 115.

[0042] In some examples, refer to Figure 1 and Figure 4 Two groups of limiting strips 112 are symmetrically and fixedly connected to the upper surface of the workbench 100. The first clamping plate 114 and the second clamping plate 115 are both provided with sliding grooves matching the limiting strips 112. The first clamping plate 114 and the second clamping plate 115 are limited by using the mutual cooperation of the limiting strips 112 and the sliding grooves, so that the first clamping plate 114 and the second clamping plate 115 can only move parallel, thus facilitating the clamping of the furniture.

[0043] In some examples, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, a first threaded rod 117 is rotatably connected to the front surface of the workbench 100. One end of the first threaded rod 117 is connected by a coupling to a first motor 1171 fixedly installed on the workbench 100. The rear surface of the workbench 100 is fixedly connected to a slide rod 118. Two groups of connecting rods 1212 are symmetrically and fixedly connected to the lower surface of the fixed frame 121. One group of connecting rods 1212 is threadedly sleeved on the first threaded rod 117, and the other group of connecting rods 1212 is movably sleeved on the slide rod 118. By starting the first motor 1171 to drive the first threaded rod 117 to rotate, the fixed frame 121 is driven to move through the cooperation of the first threaded rod 117 and the connecting rods 1212. The fixed frame 121 is limited by the cooperation of the slide rod 118 and the connecting rods 1212, so as to facilitate the adjustment of the position of the grinding wheel 1242, with high flexibility and convenient for grinding multiple positions of the furniture.

[0044] In some examples, refer to Figure 5 , Figure 6 , Figure 7 , two groups of limiting grooves 1253 are symmetrically formed on the outer wall of the sleeve block 125. Two limiting blocks 1262 matching the limiting grooves 1253 are symmetrically and fixedly connected to the two side surfaces of the inner wall of the dust suction hood 126. The dust suction hood 126 is limited by the mutual cooperation of the limiting blocks 1262 and the limiting grooves 1253, so that the dust suction hood 126 can only move up and down, thus facilitating the contact between the dust suction hood 126 and the surface of the furniture to adsorb the dust and debris generated during processing;

[0045] Exemplarily, four groups of symmetric balls 1261 are movably installed at the bottom end of the dust suction hood 126. The balls 1261 installed at the bottom end of the dust suction hood 126 facilitate the movement of the dust suction hood 126 on the surface of the furniture, so as to facilitate the dust suction of multiple positions of the furniture in cooperation with the grinding wheel 1242.

[0046] In some examples, refer to Figure 5 and Figure 7 , fixed blocks 1251 are symmetrically and fixedly connected to the outer walls on both sides of the sleeve block 125. Springs 1252 are fixedly connected to the bottom ends of the fixed blocks 1251, and the bottom ends of the springs 1252 are fixedly connected to the upper surface of the dust suction hood 126.

[0047] When it is necessary to use the grinding wheel 1242 to grind the furniture, the second cylinder 123 drives the dust suction hood 126 to descend. After the dust suction hood 126 contacts the surface of the furniture, at this time, there is still a certain distance between the grinding wheel 1242 and the furniture. The grinding wheel 1242 continues to descend, and the sleeve block 125 cooperates with the dust suction hood 126 to squeeze the spring 1252, driving the sleeve block 125 to move. When the grinding wheel 1242 contacts the surface of the furniture, the dust suction hood 126 is in close contact with the surface of the furniture, thus facilitating dust suction.

[0048] In some examples, refer toFigure 1 , Figure 2 , Figure 4 , on one side surface of the workbench 100, a dust suction box 127 is fixedly connected. On the upper surface of the dust suction box 127, a corrugated pipe 1271 is fixedly connected. One end of the corrugated pipe 1271 away from the dust suction box 127 is fixedly connected to the outer wall of the dust suction hood 126. The corrugated pipe 1271 is communicated with the dust suction hood 126. Dust suction is carried out through the dust suction hood 126. Dust and debris are sucked into the interior of the dust suction box 127 through the corrugated pipe 1271 for collection, thereby preventing the staff from inhaling dust into the lungs, reducing the impact of debris on the staff, and facilitating the grinding and processing of furniture;

[0049] Exemplarily, a second support column 1272 is fixedly connected to the bottom end of the dust suction box 127, and the dust suction box 127 is supported by the second support column 1272.

[0050] The working principle of the present utility model is as follows: When in use, the item to be ground is placed on the upper surface of the placement plate 1121, and the item to be ground is limited by the limiting plate 111. The first cylinder 113 is started, and the first cylinder 113 drives the connecting block 1142 to move in cooperation with the telescopic rod 1131. The connecting block 1142 drives the first clamping plate 114 to move, the first clamping plate 114 drives the first rack 1141 to move, and the first rack 1141 drives the gear 116 to rotate. By the rotation of the gear 116, the second rack 1151 is driven to move, so that the first clamping plate 114 and the second clamping plate 115 can be simultaneously driven to move closer to the center, thereby limiting and clamping the item to be clamped;

[0051] The first motor 1171 is started, and the first motor 1171 drives the first threaded rod 117 to rotate. The first threaded rod 117 drives the fixed frame 121 to move left and right through the connecting rod 1212. By starting the second motor 122, the second motor 122 drives the second cylinder 123 to move on the fixed frame 121 in cooperation with the second threaded rod, so that the position of the grinding wheel 1242 can be adjusted, thereby facilitating the processing of the item to be ground;

[0052] The second cylinder 123 drives the grinding wheel 1242 to descend. Through the mutual cooperation of the spring 1252 and the fixed block 1251, the dust suction hood 126 is in close contact with the item to be ground. The item to be ground is processed by the grinding wheel 1242. Dust and debris generated during the grinding process are sucked into the interior of the dust suction box 127 through the mutual cooperation of the dust suction hood 126 and the corrugated pipe 1271, and the debris and dust are collected by the dust suction box 127, thereby preventing the debris and dust from damaging the health of the staff.
