In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.
[0031] The technical scheme of the utility model will be further explained below in combination with the drawings and through specific embodiments.
[0032] As Figures 1 to 3As shown, the embodiment provides a machining tool, which comprises a machining table 1 and a dust removal device 2. The machining table 1 is provided with a tool relief groove 11 and a clamping device 14. The upper surface of the machining table 1 is used for placing a part 10 to be machined. When the part 10 is placed on the machining table 1, the part 10 will cover the tool relief groove 11. Then the part 10 is fixed by the clamping device 14 to avoid the movement of the part 10 relative to the machining table 1. Then the part 10 can be cut by a tool. The tool relief groove 11 is used for avoiding the position of the tool. When the part 10 is cut, a large amount of dust will be generated, and cutting heat will also be generated, which will cause the temperature of the dust to rise. If the high-temperature dust is not cleaned in time, the high-temperature dust falling on the surface of the part 10 may damage the part 10. In addition, too much dust will also affect the machining environment. In order to solve this problem, the machining table 1 is provided with a plurality of dust removal grooves 12. The plurality of dust removal grooves 12 are arranged at intervals and are connected with the tool relief groove 11. The dust removal device 2 comprises a plurality of dust removal pipes 21 and a dust collector 22. One end of the plurality of dust removal pipes 21 is connected with the plurality of dust removal grooves 12 one by one. The other end of the plurality of dust removal pipes 21 which is not connected with the dust removal grooves 12 is connected with the dust collector 22. The dust collector 22 can suck the dust on the machining table 1 through the dust removal pipes 21.
[0033] In specific implementation, as shown in the drawings, Figure 2 The tool relief groove 11 is arranged according to the cutting position of the part 10. The length of the tool relief groove 11 is generally long. One end of the dust removal groove 12 is connected with the tool relief groove 11, and the other end penetrates through the side edge of the machining table 1, so that the dust removal pipe 21 and the tool relief groove 11 can be connected. According to different cutting positions, the distance between the dust generation position and a certain fixed tool relief groove 11 is different. The arrangement of the plurality of dust removal grooves 12 can make the distance between the dust generation position and at least one tool relief groove 11 be the minimum distance. The dust removal pipe 21 connected with the dust removal groove 12 closest to the dust generation position can be selected for dust removal. When the part 10 is cut, a cutting groove will be formed on the part 10, which makes a large area above the tool relief groove 11 directly connected with the atmosphere. At this time, the negative pressure drop is obvious, the negative pressure influence area is reduced, and only the dust near the dust removal groove 12 can be sucked, but the dust cannot be sucked through the channel formed by the tool relief groove 11 and the lower surface of the part 10. However, by arranging a plurality of dust removal pipes 21, the dust removal pipe 21 connected with the dust removal groove 12 in front of or at the machining position is opened, so that the negative pressure influence area can be expanded to the vicinity of the machining point, and the dust removal effect is better. The dust removal rate can be effectively improved, and a large amount of high-temperature dust can be prevented from accumulating on the tool relief groove 11 and the part 10, and the surface of the part 10 can be prevented from being damaged due to long-time contact with high-temperature dust.
[0034] Optionally, a control valve 211 is installed on the dust collection pipe 21, and a position sensor is installed on the processing table 1. The position sensor is signal-connected to the control valve 211 and is used to detect the processing position of the part 10. In specific implementation, since the tool moves to cut the part 10, the position sensor can be set to detect the position of the tool cutting the part 10, that is, the position of the tool is identified as the processing position of the part 10. The number of position sensors is the same as the number of dust collection tanks 12, and one position sensor corresponds to one dust collection tank 12. When a position sensor detects that the tool has entered the preset dust collection range, it controls the control valve 211 on the dust collection pipe 21 connected to the dust collection tank 12 to open, while the other control valves 211 are closed, so that the dust is sucked into the dust collector 22 through the dust collection pipe 21. Alternatively, when a position sensor detects that the tool has entered a preset range, the control valve 211 on the dust removal pipe 21 connected to the dust removal tank 12 is opened, while the other control valves 211 are closed after a preset time, so as to avoid the dust removal component 2 reducing the suction force of dust during the switching of control valves 211.
[0035] In this embodiment, as Figure 3 As shown, the dust collection tank 12 has a V-shaped structure. The V-shaped design means that the cross-sectional area of the dust collection tank 12 gradually decreases from top to bottom. According to the principle of fluid continuity, for the same flow rate, the smaller the area, the faster the airflow velocity, and the faster the airflow velocity, the better the dust collection effect. In addition, the V-shaped structure design can increase the negative pressure influence area. The V-shaped structure helps to form a larger negative pressure area near the opening of the dust collection tank 12, which is beneficial for dust collection. Furthermore, the gravity of the dust at the opening can provide a component force in the direction of dust flow, promoting the dust removal process.
[0036] In this embodiment, the tool groove 11 is an annular groove. The structure of the tool groove 11 is determined by the machining path of the part 10. On the one hand, while meeting the requirements of the machining path, the annular tool groove 11 can also prevent dust from accumulating at a certain end of the tool groove 11, making the dust suction faster.
[0037] Optionally, the machining table 1 is further provided with a through groove 13, one end of the through groove 13 is communicated with the tool relief groove 11, and the other end penetrates the side edge of the machining table 1. In the embodiment, the dust collector 22 forms a negative pressure cavity at the dust removal groove 12 by suction, so as to realize dust suction. When the dust generated by the machining of the part 10 diffuses to the tool relief groove 11 and the surface of the part 10, the negative pressure generated by the dust collector 22 can suck the dust into the storage box of the dust collector 22 through the dust removal groove 12 and the dust removal pipe 21, so as to complete the rapid collection and treatment of the dust. The through groove 13 can avoid that, in the initial stage of machining the part 10, that is, when the tool relief groove 11 is basically or entirely covered by the part 10, the vacuum power of the dust collector 22 is too high, so that the tool relief groove 11 and the dust removal groove 12 reach a vacuum environment. The through groove 13 is used to communicate the tool relief groove 11 and the atmosphere. As the cutting of the part 10 continues, the cut part 10 can no longer cover the tool relief groove 11, so it is not necessary to rely on the through groove 13 to communicate the tool relief groove 11 and the atmosphere.
[0038] Optionally, the clamping piece 14 includes a base, a pressing rod and a connecting rod, the base is arranged on the machining table 1, one end of the pressing rod is rotationally connected with the base, and the middle segment of the pressing rod is detachably connected with the machining table 1 through the connecting rod, so that the other end of the pressing rod presses against the part 10 on the machining table 1. The clamping piece 14 is used to press the edge excess material of the part 10, so that the middle part and the edge excess material of the part 10 can be close to the upper surface of the machining table 1, the negative pressure leakage can be reduced, the negative pressure can be transmitted along the tool relief groove 11, and the dust suction capacity of the machining tooling is improved. In specific implementation, since one end of the pressing rod can be rotationally connected with the machining table 1, different thicknesses of the part 10 can be adapted by adjusting the included angle between the pressing rod and the machining table 1. When the other end of the pressing rod abuts against the part 10, the connecting rod connected with the pressing rod can be connected with the machining table 1, so that the pressing rod and the machining table 1 are fixed. After the middle segment of the pressing rod is disconnected with the machining table 1, the pressing rod can be rotated around the base, so that the other end of the pressing rod is away from the machining table 1, and the part 10 clamped between the pressing rod and the machining table 1 can be taken out.
[0039] Optionally, the pressing rod is provided with a mounting groove, one end of the connecting rod is arranged in the mounting groove, and the other end of the connecting rod is detachably connected with the machining table 1. In the embodiment, the connecting rod is a long rod nut, the machining table 1 is provided with a mounting hole, the mounting hole is provided with an internal thread, the long rod nut is arranged in the mounting groove, the nut part of one end of the long rod nut is located on the side of the pressing rod away from the machining table 1, and the threaded part of the other end of the long rod nut is threadedly connected in the mounting hole.
[0040] Optionally, the upper surface of the machining table 1 comprises a machining area and a fixing area, the fixing area is arranged around the outer periphery of the machining area, the knife groove 11 is arranged in the machining area, one end of the clamping piece 14 is arranged in the fixing area, and the other end of the clamping piece 14 can be moved to the machining area to press the part 10 to be machined on the machining table 1. In particular, the part 10 is located in the machining area, and the connection position of the clamping piece 14 and the machining table 1 is in the fixing area. The annular fixing area arranged around the outer periphery of the machining area can increase the arrangement area of the clamping piece 14, so that the clamping piece 14 can be arranged multiple along the outer periphery of the part 10, thereby enhancing the stability of the part 10.
[0041] In the embodiment, the upper surface of the machining area is an arc surface, and the arc surface is in contact with the outer surface of the part 10 to be machined. In other embodiments, the upper surface of the machining area can be adjusted according to the shape of the part 10 to be machined, so that the part 10 can be placed stably in the machining area.
[0042] Optionally, the machining tooling further comprises a supporting leg 3 arranged below the machining table 1, and the supporting leg 3 is used to make the machining table 1 located at a predetermined height. In particular, the length of the supporting leg 3 in the vertical direction can be adjusted, so that the machining table 1 can be located at a height convenient for the operator to operate.
