Description

Technical Field

[0001] The utility model relates to the technical field of screw rod guide rail protection devices, and more specifically to a chip cleaning device for a mechanical processing machine tool. Background Art

[0002] In metal machining, machine tools are often used to perform operations such as drilling, grinding, planing and milling on metals. During these processes, a large amount of chips will be generated. These chips have value for reuse, so the chips will be collected.

[0003] Most of the existing chip collection devices install a collection bucket under the screw guide rail and use gravity to collect the chips. However, the chips left on the machine tool guide rail and the screw surface cannot be collected in time, and will also damage the machine tool's screw guide rail and other transmission parts. In view of this, we propose a chip cleaning device for machining machine tools. Utility Model Content

[0021] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] This embodiment provides a chip cleaning device for a machining machine tool, referring to Figure 1 , including a screw nut 6. When the linear module of the machining machine tool adopts a screw slide with a guide rod 8, in order to ensure that the rotation of the screw 7 can smoothly drive the screw nut 6 to move horizontally, a chip guard plate 1 is installed at the two ends of the screw nut 6, and the two chip guard plates 1 each include a plate body 11. The plate body 11 has a second smooth hole 14 corresponding to the position of the screw nut 6 to ensure the smooth passage of the screw 7. At the same time, the plate body 11 is provided with a screw sleeve 2 at the second smooth hole 14. The screw sleeve 2 is sleeved on the outside of the screw 7 and fits the outer wall of the screw 7. , effectively reducing the gap between the guide rod 7 and the screw rod 7, preventing the chips from being stuck in the joint between the screw rod 7 and the screw nut 6. Similarly, due to the setting of the guide rod 8, a smooth hole 13 is opened at the lower part of the plate body 11 for the guide rod 8 to pass through, and a guide rod sleeve 4 is installed at the smooth hole 13 of the plate body 11. The guide rod sleeve 4 is sleeved on the outside of the guide rod 8 to prevent debris from entering the gap between the guide rod 8 and the plate body 11. When receiving chips, it can effectively prevent the chips from entering the joint position of the linear module of the machine tool, and can push the chips away to ensure the stable operation of the screw slide.

[0023] Reference Figure 2 In the working state, the guide rod 8 will be installed through the smooth hole 13. When in use, the outer wall of the guide rod 8 will slide in contact with the inner wall of the guide rod sleeve 4. The close sliding contact method can effectively reduce the phenomenon of fine and broken chips entering between the outer wall of the guide rod 8 and the inner wall of the guide rod sleeve 4, and a graphite copper sleeve can be embedded in the inner wall of the guide rod sleeve 4 to achieve sliding self-lubrication and ensure long-term stable operation of sliding contact.

[0024] Reference Figure 2 The guide rod sleeve 4 is fixedly installed with an end ring 5 at one end facing the plate body 11. A through hole is provided at the edge of the end ring 5 for installing bolts. The end ring 5 is connected to the plate body 11 by bolts. A blind hole is provided at the corresponding position of the plate body 11, and a threaded groove is provided. The end plate 5 can be detachably installed on the vertical side wall of the plate body 11, and can be replaced separately after wear, which is convenient for maintenance. In addition, the guide rod sleeve 4 adopts an annular structure and has a reduced diameter at one end away from the end ring 5, which can play a role in pushing materials. When contacting the chips, the conical end face of the guide rod sleeve 4 can push the chips away from the position of the guide rod 8 and move them in all directions, thereby ensuring that the chips are smoothly pushed away from the guide rod 8.

[0025] Reference Figure 3A screw rod 7 is installed through the screw nut 6, and the screw rod 7 is arranged horizontally. The screw sleeve 2 is coaxially arranged with the screw rod 7, wherein the screw sleeve 2 includes a ring body 21, which is sleeved on the outside of the screw rod 7, and a spiral ridge 23 meshing with the screw rod 7 is installed on the inner wall of the ring body 21. Because the outer wall of the screw rod 7 has a threaded groove, the spiral ridge 23 is installed inside the ring body 21, which meshes and screws with the threaded groove on the outer wall of the screw rod 7. The spiral ridge 23 can further block the gap between the screw sleeve 2 and the screw rod 7, and can effectively seal the fine and broken chips from entering between the screw nut 6 and the screw rod 7. While cleaning the chips from the surface of the screw rod 7 for collection, it can prevent the chips from affecting the smooth operation of the screw nut 6 and the screw rod 7.

[0026] Reference Figure 4 A lug 12 is installed on the plate body 11 at the circumferential position of the smooth hole 14. The lug 12 adopts an arc structure with a radius greater than the smooth hole 14, and multiple sections of the lug 12 are arranged in a ring array. In addition, a mounting hole 15 for threading the wire 3 is opened in the lug 12. The plate body 11 can be connected to the end face of the screw nut 6 for detachable installation, which is convenient for expansion on the basis of the original screw slide and also convenient for subsequent replacement and maintenance.

[0027] Reference Figure 4 A bracket 22 is installed at the edge of the outer wall of the ring body 21, and the bracket 22 is used to install the ring body 21. At the same time, the end of the bracket 22 extends toward the plate body 1 and extends into the mounting hole 15. In addition, one end of the bracket 22 located in the mounting hole 15 is provided with a through hole that cooperates with the threading 3. During installation, the threading 3 can press the ring body 21 against the end face of the plate body 11 and connect it with the screw nut 6. The threading 3 is used to fix the ring body 21 and the plate body 11 at the same time, which reduces the disassembly and assembly steps and facilitates installation.

[0028] Reference Figure 4 The mounting hole 15 is in the shape of an arc strip, and the mounting hole 15 is provided with a baffle on the inner wall of the long side, and the length of the baffle is less than the length of the mounting hole 15. When the threading 3 is installed but not tightened, the plate body 11 can be rotated to adjust the position of the plate body 11 to facilitate adapting to different installation position relationships of the screw rod 7 and the guide rod 8. When adjusting, there is no need to completely remove the threading 3. The thickness of the baffle is equal to half the depth of the mounting hole 15, and the adjustment is convenient and quick.
