Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a quick-disassembly protective cover for CNC machine tool guideways with automatic lubrication function. Background Technology

[0002] CNC machine tools mainly consist of a bed, spindle box, feed system, CNC system, and auxiliary system. The pre-programmed CNC system controls the machine tool's various motion axes and machining tools to achieve high-precision machining of workpieces. In daily use, the greatest damage to CNC machine tools is the corrosion of the guide rails caused by a humid working environment, affecting their service life. Currently, many CNC machine tools are equipped with protective covers for the guide rails to protect them and prevent dust or other debris from falling into the guide rails and affecting the normal operation of the machine tool.

[0003] Existing CNC machine tool guideway protective covers, installed on the side of the CNC machine tool, protect the internal guideways from dust. However, during the movement of the protective cover on the CNC machine tool, there is significant friction, causing wear on the bottom of the cover. Furthermore, sliding the cover is difficult and requires frequent lubrication, which is also time-consuming and inconvenient. Automatic lubrication of the cover's sliding position is not convenient. Moreover, after prolonged use on the CNC machine tool, the inner surface of the cover accumulates oil, dust, and debris from workpiece machining, making cleaning and maintenance on the CNC machine tool inconvenient. It is also difficult to quickly remove the protective cover from the CNC machine tool for cleaning and maintenance.

[0004] Therefore, a quick-release protective cover for CNC machine tool guideways with automatic lubrication function is proposed to solve the problems mentioned above. Utility Model Content

[0007] Preferably, the support bar is a long strip structure and is horizontally fixed to the top of the machine tool body. The inner side of the top of the protective cover slides over the top of the support bar, and the two ends of the support bar have connecting holes.

[0008] Preferably, the connecting hole is a threaded hole structure, the bottom end of the limiting bolt is threaded into the connecting hole, and a limiting groove is opened at the top of the protective cover and directly above the support bar.

[0009] Preferably, the length of the limiting groove is less than the length of the protective cover, the limiting bolt slides through the limiting groove, and a rubber pad is sleeved on the top of its surface, the rubber pad slidingly overlapping the top of the protective cover.

[0010] Preferably, both the sliding groove and the slide rail are elongated structures and are horizontally arranged. The outer side of the sliding groove has an installation groove. The inner end of the lubricating oil container is horizontally slidably inserted into the installation groove without protruding into the interior of the sliding groove. The top outer end of the lubricating oil container has an opening. A cover plate is installed at the top of the opening. Bolts for fastening the cover plate and the lubricating oil container are connected at the four corners of the top of the cover plate. An oil adding tube for adding lubricating oil is fixed at the middle of the top of the cover plate, located on the outer side of the machine tool body.

[0011] Preferably, the inner end of the lubricating oil container has an insertion groove, the inner end of the lubricating sponge is inserted into the insertion groove, its outer end protrudes into the sliding groove and contacts and lubricates the side of the slide rail, and the inner side of the lubricating sponge is connected to a snap-fit ​​plate, which is slidably snap-fitted into the interior of the lubricating oil container.

[0012] Preferably, the surface of the snap-fit ​​plate has uniformly opened lubricating oil flow holes, and a guide rod is fixed in the middle of the inside of the lubricating oil container and at the position on both sides of the insertion slot. The guide rod slides through the lubricating oil flow holes in the middle of the two sides of the snap-fit ​​plate, and a spring is sleeved on the surface of the guide rod at the position on the outside of the snap-fit ​​plate.

[0013] Preferably, a support plate is fixed on the outer side of the machine tool body and at the bottom of the outer side of the mounting groove. The surface of the support plate has a mounting hole. The positioning rod slides through the mounting hole, and a limit plate is fixed at its bottom end.

A lubricating oil collection box is installed on the outside of the sliding groove through the mounting groove and support plate. Inside the lubricating oil collection box, a snap-fit ​​plate is elastically installed through a guide rod and spring. A lubricating sponge is connected to the outside of the snap-fit ​​plate. The side of the lubricating sponge protrudes into the sliding groove. Therefore, during the sliding and pushing of the protective cover on the front of the machine tool body, the side of the slide rail contacts the lubricating sponge and pushes the lubricating sponge into the lubricating oil collection box. After the slide rail slides past the lubricating sponge, the spring bounces outward and the snap-fit ​​plate and lubricating sponge return to their original positions. Thus, the lubricating oil inside the lubricating oil collection box passes through the lubricating oil flow hole and wets the lubricating sponge. After the lubricating sponge is squeezed and pushed, it squeezes out the wetted lubricating oil, which adheres to the side of the slide rail and flows downward, thus wetting the sliding groove and reducing the frictional resistance of the slide rail and the protective cover. In this way, the slide rail can be automatically lubricated, which is convenient, keeps the protective cover sliding smoothly, and reduces wear.

[0015] 2. By fixing a support plate to the bottom of the outer side of the mounting groove, and elastically installing a positioning rod at the bottom of the support plate via a tension spring, after the inner end of the lubricating oil container is inserted into the mounting groove, the tension spring pulls the positioning rod upward, causing the top of the positioning rod to insert into the positioning groove, thereby positioning and stably installing the lubricating oil container, and facilitating quick disassembly, replacement and maintenance of the lubricating oil container.

[0016] 3. By fixing a support bar at the top of the machine tool body and opening a limiting groove at the top of the protective cover, a limiting bolt that slides through the limiting groove is threaded to both ends of the support bar to limit the movement of the protective cover and prevent it from moving off the machine tool body. Moreover, after removing the limiting bolt, the protective cover can be slid out from both ends of the machine tool body and removed, which is convenient and quick. After removing the protective cover from the machine tool body, it is easy to thoroughly clean the dust and oil stains adhering to the inside of the protective cover. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example:

[0020] Please see Figure 1 - Figure 6This embodiment of a CNC machine tool guide rail quick-disassembly protective cover with automatic lubrication function includes a machine tool body 1. A protective cover 4 is slidably installed on the front of the machine tool body 1. A support bar 5 is provided between the top of the protective cover 4 and the top of the machine tool body 1 for sliding movement of the top of the protective cover 4. Limiting bolts 2 are connected to the two ends of the top of the support bar 5 to limit the movement of the protective cover 4. A sliding groove 9 is provided between the bottom of the protective cover 4 and the bottom of the outer side of the machining table of the machine tool body 1. A slide rail 6 is fixed to the bottom of the protective cover 4 and slides into the sliding groove 9. A lubricating oil container 8 is installed on the outer side of the sliding groove 9. A lubricating sponge 14 for lubricating the side of the slide rail 6 is connected to the inner end of the lubricating oil container 8. A positioning rod 18 is elastically provided at the bottom of the lubricating oil container 8.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, both the sliding groove 9 and the slide rail 6 are elongated structures and are horizontally arranged. The outer side of the sliding groove 9 has an installation groove 12. The inner end of the lubricating oil container 8 is horizontally inserted into the installation groove 12 without protruding into the interior of the sliding groove 9. The top outer end of the lubricating oil container 8 has an opening 23. A cover plate 10 is installed at the top of the opening 23. Bolts 16 for fastening the cover plate 10 and the lubricating oil container 8 are connected at the four corners of the top of the cover plate 10. An adding tube 15 for adding lubricating oil is fixed at the middle of the top of the cover plate 10 and located on the outer side of the machine tool body 1.

[0022] It should be noted that the inner end of the lubricating oil container 8 has an insertion groove 26, the inner end of the lubricating sponge 14 is inserted into the insertion groove 26, its outer end protrudes into the sliding groove 9, and contacts and lubricates the side of the slide rail 6. The inner side of the lubricating sponge 14 is connected to a snap-fit ​​plate 25, which is slidably snap-fitted into the inside of the lubricating oil container 8.

[0023] It should be noted that the surface of the snap-fit ​​plate 25 is evenly provided with lubricating oil flow holes 24. Inside the lubricating oil container 8, in the middle and on both sides of the insertion slot 26, there is a guide rod 22. The guide rod 22 slides through the lubricating oil flow holes 24 in the middle on both sides of the snap-fit ​​plate 25. A spring 21 is sleeved on the surface of the guide rod 22 at the position on the outside of the snap-fit ​​plate 25.

[0024] During the sliding and pushing process of the protective cover 4 on the front of the machine tool body 1, the side of the slide rail 6 contacts the lubricating sponge 14 and pushes the lubricating sponge 14 into the lubricating oil container 8. After the slide rail 6 slides past the lubricating sponge 14, the spring 21 bounces outward and the locking plate 25 and the lubricating sponge 14 are reset.

[0025] The lubricating oil inside the lubricating oil container 8 passes through the lubricating oil flow hole 24 and soaks the lubricating sponge 14. When the lubricating sponge 14 is squeezed and pushed, it squeezes out the soaked lubricating oil, so that the squeezed lubricating oil adheres to the side of the slide rail 6 and flows downward, thereby soaking the lubricating groove 9, reducing the frictional resistance of the slide rail 6 and the protective cover 4. In this way, the slide rail 6 can be automatically lubricated, which is more convenient, keeps the protective cover 4 smoothly pushed and pulled, and reduces wear.

[0026] like Figure 3 , Figure 5 and Figure 6 As shown, a support plate 7 is fixed on the outer side of the machine tool body 1 and at the bottom of the outer side of the mounting groove 12. The surface of the support plate 7 has a mounting hole 13. The positioning rod 18 slides through the mounting hole 13, and a limit plate 19 is fixed at its bottom end. A tension spring 17 connecting the limit plate 19 and the support plate 7 is sleeved on the surface of the positioning rod 18. A positioning groove 20 is opened at the bottom end of the lubricating oil container 8. The top end of the positioning rod 18 slides vertically into the positioning groove 20.

[0027] After the inner end of the lubricating oil container 8 is inserted into the mounting groove 12, the tension spring 17 pulls the positioning rod 18 upward, so that the top end of the positioning rod 18 is inserted into the positioning groove 20, thereby positioning and stably installing the lubricating oil container 8, and facilitating quick disassembly, replacement and maintenance of the lubricating oil container 8.

[0028] like Figure 3 and Figure 4 As shown, the support bar 5 is a long strip structure and is horizontally fixed to the top of the machine tool body 1. The inner side of the top of the protective cover 4 is slidably connected to the top of the support bar 5. The two ends of the support bar 5 have connection holes 11.

[0029] It should be noted that the connecting hole 11 is a threaded hole structure. The bottom end of the limit bolt 2 is threaded into the connecting hole 11. The top of the protective cover 4 and the position directly above the support bar 5 are provided with a limit groove 3.

[0030] It should be noted that the length of the limiting groove 3 is less than the length of the protective cover 4. The limiting bolt 2 slides through the limiting groove 3, and a rubber pad 27 is sleeved on the top of its surface. The rubber pad 27 slides and overlaps the top of the protective cover 4.

[0031] A limiting bolt 2 is threaded through both ends of the support bar 5 and slides through the limiting groove 3 to limit the movement of the protective cover 4, preventing the protective cover 4 from moving and falling off the machine tool body 1. Moreover, after removing the limiting bolt 2, the protective cover 4 can be slid out from both ends of the machine tool body 1 and removed, which is convenient and quick. In addition, after removing the protective cover 4 from the machine tool body 1, it is easy to thoroughly clean the dust and oil stains adhering to the inside of the protective cover 4.

[0032] The working principle of the above embodiments is as follows: A sliding groove 9 is provided at the bottom of the outer side of the machining table of the machine tool body 1. The slide rail 6 at the bottom of the protective cover 4 is slidably inserted into the sliding groove 9. A lubricating oil container 8 is installed on the outside of the sliding groove 9 through the mounting groove 12 and the support plate 7. Moreover, a snap-fit ​​plate 25 is elastically slidably installed inside the lubricating oil container 8 through the guide rod 22 and the spring 21. A lubricating sponge 14 is connected to the outside of the snap-fit ​​plate 25, and the side of the lubricating sponge 14 protrudes into the sliding groove 9.

[0033] Therefore, during the sliding and pushing process of the protective cover 4 on the front of the machine tool body 1, the side of the slide rail 6 contacts the lubricating sponge 14 and pushes the lubricating sponge 14 into the lubricating oil container 8. After the slide rail 6 slides past the lubricating sponge 14, the spring 21 bounces outward and the locking plate 25 and the lubricating sponge 14 are reset.

[0034] Therefore, the lubricating oil inside the lubricating oil container 8 passes through the lubricating oil flow hole 24 and soaks the lubricating sponge 14. When the lubricating sponge 14 is squeezed and pushed, it squeezes out the soaked lubricating oil, so that the squeezed lubricating oil adheres to the side of the slide rail 6 and flows downward, thereby soaking the lubricating groove 9, reducing the frictional resistance of the slide rail 6 and the protective cover 4. In this way, the slide rail 6 can be automatically lubricated, which is more convenient, keeps the protective cover 4 smoothly pushed and pulled, and reduces wear.

[0035] By fixing the support plate 7 to the bottom outer side of the mounting groove 12, and elastically installing the positioning rod 18 at the bottom of the support plate 7 via the tension spring 17, after the inner end of the lubricating oil container 8 is inserted into the mounting groove 12, the tension spring 17 pulls the positioning rod 18 upward, so that the top end of the positioning rod 18 is inserted into the positioning groove 20, thereby positioning and stably installing the lubricating oil container 8, and facilitating quick disassembly, replacement and maintenance of the lubricating oil container 8.

[0036] By fixing a support bar 5 at the top of the machine tool body 1 and opening a limiting groove 3 at the top of the protective cover 4, a limiting bolt 2 that slides through the limiting groove 3 is threaded to both ends of the support bar 5 to limit the movement of the protective cover 4 and prevent the protective cover 4 from moving and falling off the machine tool body 1. Moreover, after removing the limiting bolt 2, the protective cover 4 can be slid out from both ends of the machine tool body 1 and removed, which is convenient and quick. Furthermore, after removing the protective cover 4 from the machine tool body 1, it is easy to thoroughly clean the dust and oil stains adhering to the inside of the protective cover 4.

[0037] 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.
