DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0028] like Figure 1 A schematic diagram of the three-dimensional structure of the metal cutting device is shown, which includes a frame 1, a tool 24 and a material clamping part 4, wherein the frame 1 includes a horizontal part 11 and a vertical part 12 arranged perpendicular to each other, the horizontal part 11 includes a accommodating cavity 11a with an open top, the top of the cavity is covered with a fixed plate 11b and a movable plate 11c arranged on both sides of the fixed plate 11b, the two ends of the movable plate 11c are rotatably connected to the side of the accommodating cavity 11a through a short shaft 11d, and the short shaft of the movable plate is connected through a gear or a pulley transmission. The device also includes a transmission mechanism 5 for driving the movable plate 11c to rotate, the tool 24 is installed on the vertical part 12 through a tool holder 23, and a hook-shaped body 3 is installed at the bottom of the tool holder 23, and the hook-shaped body 3 moves synchronously with the tool holder 23, and the material clamping part 4 is installed at the upper end of the fixed plate 11b for clamping metal parts.

[0029] When the tool holder 23 drives the hook-shaped body 3 to move synchronously, the transmission mechanism 5 is connected and the movable plate 11c is driven to rotate. After the movable plate 11c rotates, the cutting waste falls into the accommodating cavity 11a. The side of the movable plate 11c with cutting waste turns to the accommodating cavity 11a, and the other side turns to the outside of the accommodating cavity 11a. The present invention drives the movable plate 11c to rotate through the operation of the tool holder 23, so that the cutting waste on its surface falls into the accommodating cavity 11a, realizing the immediate cleaning of the cutting waste and avoiding the accumulation of the waste on the processing table. The present invention realizes the automatic cleaning of the cutting waste, greatly saves the labor cost, reduces the labor intensity of the workers, and improves the work efficiency. Since the cutting waste can be cleaned immediately, the pollution of the processing table and the influence on the processing accuracy of the workpiece by the waste are avoided, thereby improving the processing quality of the workpiece.

[0030] Specifically, the vertical part 12 is provided with an X-axis moving unit 21 and a Z-axis moving unit 22, the Z-axis moving unit 22 is installed on the movable part of the X-axis moving unit 21, the tool 24 is installed on the Z-axis moving unit 22 through the tool holder 23, the hook-shaped body 3 is installed on the bottom of the tool holder 23 near the side of the X-axis moving unit 21, and the tool 24 and the hook-shaped body 3 can interact in the X-axis and Z-axis directions. In addition, the fixed plate 11b is provided with a Y-axis moving unit 13, and the Y-axis moving unit 13 is connected to the material clamping part 4. The movement of the workpiece relative to the tool 24 in three axial directions is realized through the X-, Y-, and Z-axis moving units. Compared with the traditional complex automatic cleaning device, the structural design of the present invention is more concise and clear, which reduces the maintenance cost and failure rate of the whole machine.

[0031] Specific reference Figure 2 The transmission mechanism 5 includes a long rod 51 with teeth on one end and a short rod 52 vertically arranged at the other end of the long rod 51, and a gear Ⅰ53 arranged on one of the short shafts 11d close to the vertical part 12, the gear Ⅰ53 is meshed with the teeth on the long rod 51, and a slide rail 54 slidably matched with the long rod 51 and a straight hole Ⅰ121 slidably matched with the short rod 52 are provided on a back side of the vertical part 12, and the short rod 52 extends to the other side of the vertical part 12 through the straight hole Ⅰ121. During operation, the hook-shaped body 3 moves to the top or bottom of the short rod 52, and then drives the transmission mechanism 5 to move upward or downward as a whole through the short rod 52. At the same time, the teeth drive the gear I 53 to rotate, and the short rod 52 and the movable plate 11c rotate 180 degrees, and then the hook-shaped body 3 is separated from the short rod 52, so that the movable plate 11c is turned over. Of course, the movable plate 11c can also be turned over 360 degrees, or turned over 180 degrees clockwise and then turned over 180 degrees counterclockwise to restore (see Figure 3 ), which can also realize the falling of cutting waste into the accommodating cavity 11a. In addition, it should be noted that there can be multiple movable plates 11c. Specifically, in the present embodiment, gears II 14 are respectively provided on the short shafts 11d of the movable plate 11c close to the vertical portion 12, and two adjacent gears II 14 are meshed and connected.

[0032] like Figure 4A schematic diagram of one state of the material clamping part 4 is shown. Specifically, the material clamping part 4 includes a bottom support 41, a linear rail 42 and a material panel 43. The bottom support 41 is arranged at the upper end of the fixed plate 11b. Two linear rails 42 are arranged in parallel along the top of the bottom support 41. The slider of the linear rail 42 is connected to the movable end of the Y-axis moving unit 13. Two material panels 43 are symmetrically arranged, namely a left half panel 43a and a right half panel 43b. The left and right half panels are respectively hingedly connected to the sliders on the two linear rails 42. The left and right half panels can be opened or gathered along the hinge point. The ends of the two half panels that are close to each other are embedded and connected by a serrated structure. In addition, it should be noted that the serrated structure is non-through, which can limit the two half panels to be in a horizontal state when they are gathered together. In addition, a guide column 44 is provided on one side of the left and right half panels close to the vertical part 12, and an arc-shaped guide groove 122 is provided on the side of the vertical part 12 to cooperate with the guide column 44. The material clamping part 4 also includes a push rod mechanism 45 for lifting the left and right half panels. The push rod mechanism 45 includes a vertical rod 451, the lower end of the vertical rod 451 is provided with a lifting portion 452 extending to the bottom of the left and right half panels, and the upper end is provided with a cross bar 453 perpendicular to it. The side of the vertical part 12 is provided with a straight hole II 123 that slides with the vertical rod 451. This structure can allow the cutting waste left on the material panel 43 during the processing to fall to the movable plate 11c, thereby achieving cleaning. It should be noted that when using this structure, it is necessary to remove the processed workpiece and drive the material panel 43 to move toward one end of the vertical part 12 through the Y-axis moving unit 13, so that the two guide columns 44 are respectively inserted into the corresponding arc-shaped guide grooves 122. When the hook-shaped body 3 pulls the cross bar 453 upward, it drives the push rod to lift up the sides of the left and right half panels that are close to each other, and the left and right half panels turn from horizontal to tilt, and the cutting waste on their surfaces falls onto the movable plate 11c. Then the movable plate 11c is flipped again to collect the waste chips into the accommodating cavity 11a. Similar to the transmission mechanism 5, the hook-shaped body 3 can drive the push rod mechanism 45 upward or downward. In another preferred embodiment, a sliding rod is provided in the length direction of the straight hole II 123, and the vertical rod 451 is sleeved on the sliding rod, and a return spring is sleeved on the sliding rod, one end of the return spring abuts against the top of the straight hole II 123, and the other end abuts against the top of the vertical rod 451. The reset of the push rod mechanism 45 can also be achieved by the return spring. It should be particularly noted that, in a preferred embodiment, a return spring is also provided in the circular arc guide groove 122, and the return spring in the circular arc guide groove 122 can drive the guide column 44 to reset along the circular arc guide groove 122, thereby realizing the left and right half panels to return to a horizontal state. In addition, since the hinge point is close to the side of the left and right half panels, the weight of the side close to each other is much greater than the other side, and it can also be restored to a horizontal state by its own weight.

[0033] like Figure 5As shown, the inner bottom surface of the accommodating cavity 11a is inclined, and its inclination angle is preferably 15 to 30 degrees. After the cutting waste enters the accommodating cavity 11a, the waste together with the cutting fluid mixture moves downward along the inclined surface of the bottom surface. The inner surface of the accommodating cavity 11a near the bottom edge is provided with a guide groove 15, which is conducive to the rapid condensation of the cutting waste fluid. The lower side of the inclined surface of the accommodating cavity 11a is connected to a filter part 6, and the filter part 6 is connected to the inside of the accommodating cavity 11a. The filter part 6 is divided into two upper and lower areas by a horizontally arranged filter plate 61. The filtrate enters the lower area and the filter residue remains in the upper area. In this way, the mixture can be screened. In order to enable the mixture to move smoothly downward along the inclined surface of the accommodating cavity 11a, a vibration motor 8 is also provided on the outer bottom surface of the accommodating cavity 11a.

[0034] The X-axis moving unit 21, the Z-axis moving unit 22 and the Y-axis moving unit 13 in the present invention can all adopt a linear slide structure, or a linear motor structure, etc. Each electrical structure is controlled by an integrated PCL control center (not shown in the figure).

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
