The top of the lubrication box 111 is fixedly connected to the bottom of the connecting block 10, and a threaded rod 7 passes through the lubrication box 111 with a threaded connection at the penetration point. The rotating rod 112 passes through the lubrication box 111 and is rotatably connected at the penetration point. The inner wall of the rotating column 113 is fixedly connected to the outer wall of the rotating rod 112, and the outer wall of the rotating column 113 is attached to the inner wall of the machine tool 1. The outer wall of the impact column 114 is fixedly connected to the rotating rod 112. The outer wall of the L-shaped linkage column 117 is slidably connected to the inner wall of the lubrication box 111. The outer wall of the connecting column 116 is fixedly connected to the outer wall of the L-shaped linkage column 117. The top of the baffle 115 is fixedly connected to the bottom of the connecting column 116, and the bottom of the baffle 115 is attached to the inner wall of the lubrication box 111. The inner wall of the lubrication box 111 has an oil drain port 1110. The bottom of the moving block 118 is fixedly connected to the top of the L-shaped linkage column 117, and the outer wall of the moving block 118 is attached to the inner wall of the lubrication box 111. One end of the compression spring 119 is fixedly connected to the top of the moving block 118, and the other end is fixedly connected to the inner wall of the lubrication box 111.
[0018] The motor 6 is started, which drives the threaded rod 7 to rotate, allowing the threaded rod 7 to rotate in the lubrication box 111. By setting up the lubrication box 111, the rotating rod 112, the rotating column 113, the striking column 114, the baffle 115, the connecting column 116, the L-shaped linkage column 117, the moving block 118, the compression spring 119, and the oil drain port 1110, they cooperate with the threaded rod 7, allowing the lubricating oil in the lubrication box 111 to gradually flow out from the oil drain port 1110, thus solving the problem of the threaded rod 7 getting stuck during rotation due to long-term rotation.
[0019] In this embodiment, during operation: The motor 6 is started, driving the threaded rod 7 to rotate. The threaded rod 7 moves the lubrication box 111, causing the rotating column 113 to move along the inner wall of the machine tool 1. This causes the rotating rod 112 to rotate as well, causing the striking column 114 to move in a circular motion. The striking column 114 then contacts the inclined surface of the L-shaped linkage column 117, causing the L-shaped linkage column 117 to move upwards. This moves the moving block 118 upwards as well, causing the compression spring 119 to deform under the pressure of the moving block 118. Simultaneously, the connecting column 116 moves upwards along with the L-shaped linkage column 117, thereby moving the baffle 115 towards... The baffle 115 moves upward, moving away from the inner wall of the lubrication tank 111, allowing the lubricating oil in the lubrication tank 111 to slowly flow out from the drain port 1110. When the rotating rod 112 drives the striking column 114 away from the inclined surface of the L-shaped linkage column 117, the compression spring 119, which is in a compressed state, generates elastic force, thereby driving the moving block 118 to move downward to reset. The moving block 118 drives the L-shaped linkage column 117 to move downward to reset, and at the same time drives the connecting column 116 to move downward, so that the baffle 115 moves downward until the baffle 115 is in contact with the inner wall of the lubrication tank 111, preventing the lubricating oil from leaking out of the drain port 1110 and causing waste.
[0020] Please see Figures 1-6 Based on the above embodiments, in another embodiment of the present invention, the blowing device includes an air-gathering box 121, an L-shaped pressure rod 122, a sliding block 123, a piston plate 124, an air hole 125, and a moving spring 126; the outer wall of the air-gathering box 121 is fixedly connected to the outer wall of the lubrication box 111, and the threaded rod 7 passes through the air-gathering box 121 with a threaded connection at the penetration point; the outer wall of the L-shaped pressure rod 122 is fixedly connected to the side wall of the baffle 115; the sliding block 123 passes through the lubrication box 111 with a sliding connection at the penetration point, and the outer wall of the sliding block 123 is attached to the inner wall of the lubrication box 111; the outer wall of the piston plate 124 is fixedly connected to the outer wall of the sliding block 123, and the outer wall of the piston plate 124 is attached to the inner wall of the air-gathering box 121; one end of the moving spring 126 is fixedly connected to the outer wall of the moving spring 126, and the other end is fixedly connected to the outer wall of the lubrication box 111; the air hole 125 is opened on the outer wall of the air-gathering box 121.
[0021] Motor 6 drives threaded rod 7 to rotate, causing lubrication box 111 to move. When baffle 115 moves upward, the threaded rod 7 is cleaned by the cooperation of air collection box 121, L-shaped pressure rod 122, sliding block 123, piston plate 124, air hole 125, and moving spring 126 before it rotates. This solves the problem that dust on threaded rod 7 can cause damage to threaded rod 7 and lubrication box 111 due to prolonged rotation.
[0022] It also includes a clamping device for transporting materials. The clamping device is set on the worktable 9 and includes a support plate 131, an extrusion block 132, a movable pad 133, a tension spring 134, a return spring 135, and an L-shaped extrusion column 14. The bottom of the support plate 131 is fixedly connected to the top of the worktable 9, the bottom of the extrusion block 132 is slidably connected to the top of the worktable 9, the outer wall of the movable pad 133 is slidably connected to the inner wall of the extrusion block 132, and the outer wall of the movable pad 133 is in contact with the inner wall of the extrusion block 132. One end of the return spring 135 is fixedly connected to the outer wall of the movable pad 133 and the other end is fixedly connected to the inner wall of the extrusion block 132. One end of the tension spring 134 is fixedly connected to the outer wall of the support plate 131 and the other end is fixedly connected to the side wall of the extrusion block 132. The outer wall of the L-shaped extrusion column 14 is fixedly connected to the side wall of the machine tool 1.
[0023] When the lubrication box 111 moves, it drives the connecting block 10 and the worktable 9 to move together towards the center position. Through the cooperation of the support plate 131, the extrusion block 132, the moving pad 133, the tension spring 134, the return spring 135, and the L-shaped extrusion column 14, the clamping force is always kept in the same state, so that the material is always clamped and concentrated, which solves the problem of material deviation and shaking during processing.
[0024] In this embodiment, when the baffle 115 moves upward along with the L-shaped linkage column 117, the baffle 115 drives the L-shaped pressure rod 122 to move upward as well. This causes the L-shaped pressure rod 122 to press against the inclined surface of the sliding block 123, moving the sliding block 123 into the gas-gathering box 121. Consequently, the sliding block 123 drives the piston plate 124 to move into the gas-gathering box 121, allowing the piston plate 124 to discharge the gas in the gas-gathering box 121 through the air hole 125. Simultaneously, the piston plate 124 drives the moving spring 126 to move into the gas-gathering box 121. Inward movement; when the baffle 115 moves downward together with the L-shaped linkage column 117 to reset, the baffle 115 drives the L-shaped pressure rod 122 to move downward together, so that the L-shaped pressure rod 122 moves away from the inclined surface of the sliding block 123. At this time, the moving spring 126 in the compressed state generates a pulling force to drive the piston plate 124 to move and reset towards the lubrication box 111, so that the gas in the air is drawn into the gas collection box 121 from the air hole 125, thereby causing the piston plate 124 to drive the sliding block 123 to move and reset towards the lubrication box 111.
[0025] The motor 6 is started, driving the threaded rod 7 to rotate, which in turn moves the lubrication box 111 towards the material processing area. The lubrication box 111, along with the connecting block 10, moves towards the material processing area, and moves the worktable 9 together. This causes the L-shaped extrusion column 14 to press the inclined surface of the extrusion block 132, moving the extrusion block 132 towards the center position. When the material is clamped by the two sets of extrusion blocks 132, the material presses the moving pad 133, causing the moving pad 133 to move inward towards the extrusion block 132. After the material is processed, the threaded rod 7 rotates in the opposite direction, causing the lubrication box 111 to move towards the outer wall of the machine tool 1 to reset, and also causing the connecting block 10 to move towards the outer wall of the machine tool 1. This causes the worktable 9 to move towards the outer wall of the machine tool 1, moving the L-shaped extrusion column 14 away from the inclined surface of the extrusion block 132. At this time, the tension spring 134 generates tension, causing the extrusion block 132 to move towards the outer wall of the machine tool 1 to reset. The reset spring 135, which is in a compressed state, generates elasticity, causing the moving pad 133 to move towards the outer wall of the extrusion block 132 to reset.
