Description

Technical Field

[0001] This utility model relates to the field of base technology, and in particular to a vertical machining center base with a spiral chip removal groove. Background Technology

[0002] The base of a vertical machining center, as a core load-bearing component, is mainly used to support the worktable, install the chip removal system, and stabilize the overall machine structure. The base is the fundamental support component of the machine tool, bearing both static and dynamic loads to ensure machining accuracy and stability.

[0003] However, traditional vertical machining centers typically use horizontal chip removal troughs, relying on the driving force of a screw for chip removal. This single-function design leads to chip accumulation within the trough. Traditional screw blades are mostly flat, resulting in rigid collisions with chips and high frictional resistance. Furthermore, the sharp edges of traditional blades easily snag long, thin chips, causing entanglement and jamming. The large gap between the blades and the trough allows small chips to easily get stuck, requiring frequent machine stops for cleaning and resulting in long maintenance times. Simultaneously, the lack of a dedicated chip interception and guidance structure on the worktable allows chips to easily scatter outside the equipment, resulting in low collection efficiency, impacting the machining environment, and causing machining interruptions due to poor chip removal, thus reducing equipment operating efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vertical machining center base with a spiral chip removal groove, which aims to improve the problems of poor chip removal, low chip collection rate and low maintenance efficiency of traditional bases.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical machining center base with a spiral chip removal groove, comprising an inclined rail, a base fixedly connected to the outer wall of the inclined rail, a dust cover fixedly connected to the outer wall of the base, multiple first motors fixedly connected to the inner wall of the base, a drive shaft fixedly connected to the output end of each first motor, a chip removal groove fixedly connected to the inner wall of the base, multiple spiral rods slidably connected to the inner wall of the chip removal groove, a limit block fixedly connected to the outer wall of the chip removal groove, a worktable slidably connected to the inner wall of the chip removal groove, a housing fixedly connected to one side of each worktable, a second motor fixedly connected to the inner wall of the housing, a drive rod fixedly connected to the output end of each second motor, multiple gears fixedly connected to the outer wall of the drive rod, racks meshing with the tooth ends of the gears, and a quick-release assembly provided on the inner wall of the spiral rod.

[0006] Preferably, the quick-release assembly includes a slide rod, the outer wall of which slides and engages with the inner wall of the base, one end of which is fixedly connected to a slide piece, the outer wall of which is fixedly connected to a connecting rod, the outer wall of which is slidably connected to a limit rod, the outer wall of which is sleeved with a spring, and one end of which is fixedly connected to a limit piece.

[0007] Preferably, the outer wall of the limiting piece is fixedly connected to the inner wall of the spiral rod, and the spring is disposed on the inner wall of the spiral rod.

[0008] Preferably, the outer wall of the connecting rod is slidably connected to the inner wall of the screw rod, and the outer wall of the sliding plate is slidably connected to the outer wall of the screw rod.

[0009] Preferably, the outer wall of the slide rod slides and engages with the inner wall of the drive shaft.

[0010] Preferably, the outer wall of the drive shaft is rotatably connected to the inner wall of the base and the chip removal groove, and the outer walls of the plurality of racks are fixedly connected to the outer wall of the base.

[0011] Preferably, the outer wall of the transmission rod is rotatably connected to the inner wall of the multiple worktables and the housing.

[0012] Preferably, the outer walls of the plurality of worktables are provided with a plurality of guide grooves, and baffles are fixedly connected to the outer walls of the plurality of worktables.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the inclined design of the ramp assists in chip removal. The second motor is started and drives multiple gears to rotate on the rack via the transmission rod, thereby moving the worktable within the chip removal groove. When the parts on the worktable are being die-cast, the worktable baffle and guide groove cooperate to ensure that the chips accurately enter the chip removal groove. At the same time, the first motor is started and drives the spiral rod to rotate within the chip removal groove via the transmission shaft. The arc-shaped inclined blades of the spiral rod can reduce the rigid collision and friction of the chips, and the rounded edges of the blades can prevent chips from getting caught. The wear-resistant scraper of the blades can not only prevent small chips from getting stuck, but also scrape off the residue on the groove wall, achieving efficient and concentrated collection of chips, improving the smoothness and efficiency of chip removal, reducing jamming failures, and lowering maintenance costs.

[0015] 2. In this utility model, by pushing the sliding plate, the connecting rod slides simultaneously on the outer wall of the limiting rod and the inner wall of the spiral rod, and compresses the spring, so that the sliding rod is separated from the base and the transmission shaft, realizing the quick disassembly of the spiral rod; during installation, it is quickly positioned according to the positioning groove of the base and the sliding groove of the transmission shaft, reducing the installation difficulty, so that the sliding rod is snapped and fixed on the inner wall of the base and the transmission shaft, which facilitates the quick replacement of worn blades, improves maintenance efficiency, reduces maintenance costs, and extends the service life of the equipment.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-4This utility model provides an embodiment of a vertical machining center base with a spiral chip removal groove, including an inclined rail 1, a base 2 fixedly connected to the outer wall of the inclined rail 1, a dust cover 3 fixedly connected to the outer wall of the base 2, multiple first motors 6 fixedly connected to the inner wall of the base 2, a transmission shaft 7 fixedly connected to the output end of the first motors 6, a chip removal groove 20 fixedly connected to the inner wall of the base 2, multiple spiral rods 9 slidably connected to the inner wall of the chip removal groove 20, a limit block 14 fixedly connected to the outer wall of the chip removal groove 20, a worktable 4 slidably connected to the inner wall of the chip removal groove 20, a housing 5 fixedly connected to one side of the multiple worktables 4, a second motor 10 fixedly connected to the inner wall of the housing 5, a transmission rod 11 fixedly connected to the output end of the second motor 10, multiple gears 12 fixedly connected to the outer wall of the transmission rod 11, a rack 13 meshing with the tooth ends of the gears 12, and a quick-release assembly provided on the inner wall of the spiral rods 9.

[0025] Specifically, the second motor 10 is started to drive the transmission rod 11 to rotate, and the transmission rod 11 then drives the gear 12 to mesh with the rack 13, so that the gear 12 rotates on the rack 13, thereby limiting the inner wall of the sliding chip removal groove 20 of the worktable 4 by the limiting block 14. At the same time, the first motor 6 is started to drive the screw rod 9 to rotate on the inner wall of the chip removal groove 20 through the transmission shaft 7. The outer wall of the worktable 4 is fixedly connected to a baffle. When the part is processed, the chips generated are intercepted by the baffle of the worktable 4. At the same time, the dust cover 3 prevents the chips from flying out. The chips then fall into the chip removal groove 20 through the guide groove opened on the worktable 4. The blades carry the debris forward to the collection groove on the inner wall of the base 2 for centralized collection. By designing the blade cross-section of the spiral rod 9 as arc-shaped and inclined, the rigid collision between the debris and the blade is reduced. At the same time, the arc-shaped surface guides the chips to slide along the blade surface, reducing the frictional resistance between the debris and the blade. Secondly, the edges of the blades are rounded to prevent sharp edges from snagging the chips. Wear-resistant scrapers are set on the side where the blades contact the groove, which not only prevents small chips from getting stuck in the gap, but also scrapes off the chips adhering to the groove wall, reducing residue, improving the smoothness and efficiency of chip removal, reducing jamming failures, and lowering maintenance costs.

[0026] Reference Figure 2 , Figure 4 and Figure 5The quick-release assembly includes a slide rod 19, the outer wall of which slides and engages with the inner wall of the base 2. One end of the slide rod 19 is fixedly connected to a slide piece 8, and the outer wall of the slide piece 8 is fixedly connected to a connecting rod 15. The outer wall of the connecting rod 15 is slidably connected to a limiting rod 16, and the outer wall of the limiting rod 16 is fitted with a spring 17. One end of the limiting rod 16 is fixedly connected to a limiting piece 18. The outer wall of the limiting piece 18 is fixedly connected to the inner wall of the spiral rod 9, and the spring 17 is disposed on the inner wall of the spiral rod 9. The outer wall of the connecting rod 15 is slidably connected to the inner wall of the spiral rod 9, and the outer wall of the slide piece 8 is slidably connected to the outer wall of the spiral rod 9. The outer wall of the slide rod 19 slides and engages with the inner wall of the drive shaft 7.

[0027] Specifically, pushing the slider 8 causes the connecting rod 15 to slide against the limiting rod 16 on the inner wall of the spiral rod 9, while simultaneously compressing the spring 17. The limiting piece 18 then provides a stop. At the same time, the slider 8 causes the sliding rod 19 to slide out from the inner wall of the base 2 and the drive shaft 7, releasing the direct lock between the spiral rod 9 and the base 2 and drive shaft 7, allowing for quick removal of the spiral rod 9. During installation, pushing the slider 8 causes the connecting rod 15 to compress the spring 17, and then the positioning groove of the base 2 and the sliding groove of the drive shaft 7 are used for quick positioning, reducing installation difficulty. After aligning the spiral rod 9, the slider 8 is released. Under the restoring force of spring 17, the connecting rod 15 is pushed to slide and reset, thereby driving the slide bar 19 to slide and engage with the inner wall of the base 2 and the drive shaft 7 through the slide plate 8, quickly locking and completing the installation; the quick-release component achieves the effect of rapid disassembly and installation, solving the cumbersome problem of traditional bolt connection, improving efficiency, facilitating quick replacement after blade wear, reducing equipment downtime for maintenance, lowering maintenance costs, and extending equipment service life; at the same time, the elasticity of spring 17 ensures that the slide bar 19 is firmly engaged, preventing the screw rod 9 from loosening during operation and ensuring chip removal stability.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The outer wall of the drive shaft 7 is rotatably connected to the inner wall of the base 2 and the chip removal groove 20, and the outer walls of the multiple racks 13 are fixedly connected to the outer wall of the base 2; the outer wall of the drive rod 11 is rotatably connected to the inner wall of the multiple worktables 4 and the outer shell 5.

[0029] Specifically, when the first motor 6 is started, it drives the transmission shaft 7 to rotate on the inner wall of the base 2 and the chip removal groove 20, thus limiting the transmission shaft 7; the base 2 limits the multiple racks 13, causing the gear 12 to rotate on the racks 13; when the second motor 10 is started, it drives the transmission rod 11 to rotate on the inner wall of the multiple worktables 4 and the outer shell 5, thus limiting the transmission rod 11.

[0030] Reference Figure 2 and Figure 3Multiple guide grooves are provided on the outer walls of multiple worktables 4, and baffles are fixedly connected to the outer walls of multiple worktables 4.

[0031] Specifically, when the parts on the workbench 4 are processed, debris is generated. The debris is then intercepted by the baffle on the outer wall of the workbench 4 to prevent it from falling outside the equipment and reducing the debris collection rate.

[0032] Working Principle: This utility model mainly consists of an inclined plane 1, a base 2, and a dust cover 3. The inclined plane 1 is an inclined surface, allowing the overall running direction of the equipment to be tilted at a certain angle. When using the equipment, the second motor 10 is started, driving the transmission rod 11 to rotate on the inner wall of multiple limit blocks 14, which in turn drives multiple gears 12 to mesh with the tooth ends of the rack 13. This causes the gears 12 to rotate on the rack 13, driving the limit blocks 14 to slide on the inner wall of the chip removal groove 20, thus moving the equipment. At this time, the die casting of the parts fixed on the worktable 4 begins. The chips are intercepted by the baffles on the outer wall of the worktable 4 and discharged into the inner wall of the chip removal groove 20 through multiple guide grooves on the outer wall of the worktable 4. At the same time, the second motor 10 is started, driving the transmission rod 11 to rotate on the inner wall of multiple limit blocks 14, which in turn drives multiple gears 12 to mesh with the rack 13. This causes the gears 12 to rotate on the rack 13, driving the limit blocks 14 to slide on the inner wall of the chip removal groove 20, thus moving the equipment. At this time, the die casting of the parts fixed on the worktable 4 begins. The chips are intercepted by the baffles on the outer wall of the worktable 4 and discharged into the inner wall of the chip removal groove 20 through multiple guide grooves on the outer wall of the worktable 4. The first motor 6 drives the transmission shaft 7 to rotate, which in turn drives the screw rod 9 to rotate on the inner wall of the chip discharge groove 20 through the quick-release assembly. The screw rod 9 drives the chips forward to the collection groove on the inner wall of the base 2 for centralized collection. By designing the blade cross-section of the screw rod 9 as arc and inclined, the rigid collision between the chips and the blade is reduced. At the same time, the arc surface guides the chips to slide along the blade surface, reducing the frictional resistance between the chips and the blade. Secondly, the edge of the blade is designed with rounded corners to avoid sharp edges from snagging chips. Wear-resistant scrapers are set on the side where the blade contacts the groove, which not only prevents small chips from getting stuck in the gap, but also scrapes off the chips adhering to the groove wall, reducing residue.

[0033] This invention utilizes a sliding plate 8 to drive the connecting rod 15 to slide against the outer wall of the limiting rod 16 and the inner wall of the spiral rod 9, compressing the spring 17. The limiting plate 18 then limits the movement, simultaneously causing the sliding rod 19 to slide out from the inner wall of the base 2 until it disengages. This releases one end of the spiral rod 9 from the base 2 and locks the base 2. Simultaneously, the other end of the spiral rod 9 is unlocked from the drive shaft 7, allowing for quick disassembly of the spiral rod 9 from the inner walls of the base 2 and drive shaft 7. During installation, the sliding plate 8 drives the connecting rod 15 to compress the spring 17, allowing for quick positioning through the positioning groove on the inner wall of the base 2 and the sliding groove on the inner wall of the drive shaft 7. This secures the sliding rod 19 to the inner walls of the base 2 and drive shaft 7, achieving rapid installation. In the event of wear during prolonged operation, the blades can be quickly disassembled and replaced, reducing maintenance costs, improving maintenance efficiency, and extending the equipment's lifespan.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
