Description

Technical Field

[0001] This utility model relates to the field of machine tool devices, specifically a flow guide for a CNC machine tool. Background Technology

[0002] CNC machine tools control their movement and machining processes using digital information. Their working principle involves representing the machining process, process parameters, and tool trajectory information of the part using digital codes, and then inputting this digital information into the CNC system via an input device. The CNC system processes and calculates the input information, issuing various control signals to control the machine tool's servo system to drive the worktable, cutting tools, and other actuators to move along predetermined trajectories and speeds, thereby achieving the machining of the part.

[0003] When performing machining operations on multi-spindle, multi-channel CNC machine tools, a large amount of cutting fluid is often required. After the cutting fluid participates in the machining process, it needs to be filtered to remove the metal debris it contains. Existing multi-spindle, multi-channel machining tools have their own filtration mechanisms after each drainage channel. When sending the cutting fluid containing debris to the filtration mechanism, it is often necessary to guide it through an extended guide mechanism. However, the extended guide mechanism often extends directly above the filtration mechanism. When replacing or maintaining the filtration mechanism, the guide mechanism must be removed first, which is inconvenient for operation, installation, and use. Utility Model Content

[0004] The purpose of this invention is to provide a flow guide for a CNC machine tool to solve the problems mentioned in the background art.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see the appendix Figures 1-6 This application provides the following technical solutions.

[0025] A flow guide for a CNC machine tool includes a machine tool base 1. A filter table 2 is provided on one side of the machine tool base 1. Several machine tool drainage grooves 3 are formed on the side of the machine tool base 1 near the filter table 2. An extended flow guide 5 is provided on one side of each machine tool drainage groove 3 via an assembly assembly. A downward flow guide 6 is provided on one side of the extended flow guide 5. The lower end of the machine tool drainage groove 3 is inclined, and the side of the machine tool drainage groove 3 near the filter table 2 is lower than the other side. A flange plate is provided on the side of the extended flow guide 5 away from the machine tool base 1 for downward flow guidance. Three hanging ears 19 are provided on one side of the cover 6, and the three hanging ears 19 are respectively hung on the flange plate of the extension guide cover 5. When the machine tool is used for cutting, the cutting fluid flows through the bottom slope of the machine tool drain trough 3 towards the position of the extension guide cover 5. Since the cross-sectional area of ​​the extension guide cover 5 is larger than the cross-sectional area of ​​the machine tool drain trough 3, the waste liquid flowing down from the machine tool drain trough 3 is guided from the extension guide cover 5 to the filter table 2, and under the downward guiding action of the downward guide cover 6, it successfully falls into the filter table 2, and there will be no problem of splashing when the water flow is rapid.

[0026] The mounting assembly includes a reference plate 7, a mounting pull plate 10, and two L-shaped elastic mounting rods 15. The two L-shaped elastic mounting rods 15 are respectively mounted on the side of the machine tool base 1 near the machine tool drain trough 3. The reference plate 7 and the mounting pull plate 10 are respectively located on both sides of the extension guide shroud 5. The reference plate 7 is fixedly mounted on one side of the machine tool base 1. The reference plate 7 is fixed to the side of the machine tool base 1 near the machine tool drain trough 3 by bolts. A rotating connecting ear 8 is provided on one side of the reference plate 7. A pin connecting shaft 9 is provided on the side of the extension guide shroud 5 near the rotating connecting ear 8. The pin connecting shaft 9 is movably connected to the rotating connecting ear 8. After the extension guide shroud 5 is movably connected to one side of the machine tool base 1 through the reference plate 7, it can rotate along the rotating connecting ear 8 of the reference plate 7.

[0027] Two L-shaped elastic mounting rods 15 are respectively inserted into mounting pull plates 10 on one side. The machine tool base 1 has mounting grooves 12 on the side near the machine tool drain trough 3 and away from the reference plate 7. Assembly bolts 13 are horizontally inserted into one side of each mounting groove 12. Mounting pads 14 are fitted into the mounting grooves 12 to accommodate the assembly bolts 13. The horizontal sections of the two L-shaped elastic mounting rods 15 are inserted into the mounting grooves 12 and fitted with the assembly bolts 13. A fixing nut is fitted onto the side of the L-shaped elastic mounting rod 15 that is fitted with the assembly bolt 13. The side of the L-shaped elastic mounting rod 15 placed in the mounting groove 12 contacts the mounting pad 14. Hanging slots 11 are symmetrically provided on both sides of the mounting pull plate 10. The vertical ends of the two L-shaped elastic mounting rods 15 pass through the two hanging slots 11 respectively. Each of the slots 11 and the side near the extension guide shroud 5 is provided with a fastening block 16. One side of the fastening block 16 is in contact with the mounting pull plate 10, and the side of the fastening block 16 away from the mounting groove 12 is an inclined surface. When the extension guide shroud 5 is installed over the machine tool drain trough 3, the reference plate 7 is first fixedly connected to the machine tool base 1 with bolts. Then, the extension guide shroud 5 is rotated along the rotating connecting ear 8 so that the two slots 11 of the mounting pull plate 10 are respectively fitted with two L-shaped elastic mounting rods 15. At this time, when the mounting pull plate 10 contacts the L-shaped elastic mounting rod 15, the fastening block 16 of the L-shaped elastic mounting rod 15 is pushed by the inclined surface to bend and deform the L-shaped elastic mounting rod 15. When the mounting pull plate 10 passes over the slots 11, it elastically returns to its original position and fastens the mounting pull plate 10, so that the extension guide shroud 5 can be quickly installed and fixed.

[0028] The bent surface of the L-shaped elastic mounting rod 15 is provided with a reinforcing spring piece 17. The machine tool base 1 is provided with a compression sealing ring 18 on one side of the machine tool drain trough 3, and one side of the compression sealing ring 18 abuts against the extended guide shroud 5. The reinforcing spring piece 17 improves the elastic support strength of the L-shaped elastic mounting rod 15 and enhances the stability of the L-shaped elastic mounting rod 15 when it is attached to the extended guide shroud 5. After the mounting pull plate 10 is attached to the two fastening blocks 16, the compression sealing ring 18 is pressed and sealed against the side of the extended guide shroud 5. To prevent cutting fluid from overflowing from the joint between the extended guide shroud 5 and the machine tool base 1, the clamping force between the extended guide shroud 5 and the compression sealing ring 18 can be adjusted by selecting mounting grooves 12 of different thicknesses to install the L-shaped elastic mounting rod 15. When the mounting groove 12 is thinner, the fastening block 16 is closer to the machine tool base 1. In this case, if the mounting pull plate 10 wants the fastening block 16 to fasten the mounting pull plate 10, it can only further rotate the extended guide shroud 5 so that the end of the extended guide shroud 5 is further squeezed and sealed with the compression sealing ring 18.

[0029] When the filter mechanism on the filter table 2 needs to be disassembled, it is not necessary to remove the entire extension guide shroud 5 and the downward guide shroud 6. Simply move the two L-shaped elastic mounting rods 15 on one side to disengage the mounting pull plate 10 from the hook block 16, and then rotate the extension guide shroud 5 and the downward guide shroud 6 along the rotating connecting ear 8 until they are in a position that fits against the side of the machine tool base 1. This makes it easy to replace the filter mechanism on the filter table 2.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
