Description

Technical Field

[0001] This utility model relates to the technical field of planar vertical lathe equipment, and in particular to a dual-station planar vertical lathe. Background Technology

[0002] A planar vertical lathe is a type of lathe where the spindle axis is perpendicular to the horizontal plane and the workpiece is mounted on a horizontal rotary worktable. The "planar" in its name emphasizes that the worktable is in a horizontal position, and together with "vertical," it reflects its core structural feature—solving the problem of clamping large workpieces on traditional horizontal lathes through a vertical spindle layout.

[0003] When manufacturing certain workpieces, milling machines are often used to cut their surfaces to ensure the flatness meets practical requirements. For example, workpieces like gear chambers for diesel engines require a certain level of stability and flatness during machining. Vertical lathes feature a vertical spindle and a horizontal disc-shaped worktable, with the workpiece directly fixed to the worktable surface. This design distributes the workpiece's weight evenly across the worktable guide rails or thrust bearings, preventing spindle bending and significantly improving rigidity and stability. In existing technology, to improve machining efficiency and save energy, dual-machining-platform vertical lathes have been designed and manufactured, capable of simultaneously machining two workpieces. However, these dual-machining-platform vertical lathes lack flexibility during startup, often only offering a single-station simultaneous operation mode. In scenarios requiring only individual workpiece machining, independent startup is difficult, leading to resource waste. Utility Model Content

[0004] This utility model addresses the technical problem of the lack of flexibility and inability to switch between single and double columns when operating a dual-station planar vertical lathe. It provides a dual-station planar vertical lathe, including a worktable base, a rotating worktable and a worktable fixing frame rotatably connected above the worktable base, and a rotary motor inside the worktable base to drive the rotating worktable to rotate.

[0005] It also includes a horizontal guide rail, with a support column fixedly connected to each end of the horizontal guide rail. The horizontal guide rail has a concave structure with a guide rail groove in the middle. A threaded rod is provided in the guide rail groove. The threads on the outer circumference of both ends of the threaded rod are symmetrically distributed. A variable frequency motor is provided at one end of the horizontal guide rail. The motor rotation shaft of the variable frequency motor is fixedly connected to one end of the threaded rod.

[0006] A first connecting slide and a second connecting slide are slidably connected to the horizontal guide rail. Both the first connecting slide and the second connecting slide are fixedly connected to a height-adjustable tool holder. The bottom of the height-adjustable tool holder is provided with a tool head, which is located above the rotary worktable.

[0007] The inner side of the second connecting slide is fixedly connected to a slide connecting block. The center of the slide connecting block is provided with an internal thread through hole that matches the threaded rod. The slide connecting block is sleeved on the outer periphery of the threaded rod.

[0008] The inner side of the first connecting slide is fixedly connected to a cooperating drive device to control the first connecting slide to move horizontally together with the rotation of the threaded rod.

[0009] Preferably, in the above technical solution, the co-drive device includes a sliding vane connecting cylinder, which is a hollow structure. An adjusting ring is fixedly connected to one side of the sliding vane connecting cylinder, and the outer periphery of one side of the adjusting ring is provided with an external thread and a matching threaded ring.

[0010] Preferably, in the above technical solution, a connecting ring is fixedly connected to one side of the adjusting ring, and at least four "T"-shaped grooves pointing to the center of the ring are evenly distributed on the outer side of the connecting ring.

[0011] Preferably, in the above technical solution, the co-driving device further includes four fan-shaped cones, each of which has a "T"-shaped protrusion at its top corresponding to the "T"-shaped groove, to ensure that each fan-shaped cone can move along the "T"-shaped groove toward the center of the ring.

[0012] Preferably, in the above technical solution, each of the fan-shaped cones has an internal thread matching the threaded rod on its inner arc surface, and each pair of adjacent fan-shaped cones has two corresponding spring grooves on their sides, with a spring fixedly connected between each pair of corresponding spring grooves.

[0013] Preferably, in the above technical solution, a threaded rod mounting bracket is provided at both ends of the horizontal guide rail and in the middle, and a bearing is provided in the middle of each threaded rod mounting bracket, and the threaded rod is fixedly connected to the inner ring of the bearing.

[0014] Preferably, in the above technical solution, the two sides of the horizontal guide rail extend vertically inward with slide bars, and both sides of the first connecting slide and the second connecting slide are provided with sliding grooves that match the slide bars, so that the first connecting slide and the second connecting slide can move horizontally along the slide bars.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes a variable frequency motor to drive a threaded rod with symmetrically distributed threads at both ends, enabling a single variable frequency motor to achieve horizontal displacement of a dual-station planar vertical lathe. This saves on production costs and reduces the number of machines in operation, thereby lowering energy consumption.

[0017] This invention features a co-driving device located inside the first connecting slide. By rotating the threaded ring, it presses down on the four sector-shaped cones, causing them to retract inward until they stably contact the threaded rod, thus enabling simultaneous operation at two workstations. Conversely, by rotating the threaded ring in the opposite direction until it releases pressure on the four sector-shaped cones, the cones, under the elastic force of the springs, expand outward and disengage from the threaded rod, thus achieving single-workstation operation. This controllable switching between single and double column operation modes enhances the flexibility of the dual-workstation planar vertical lathe. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] like Figures 1-8 As shown, this utility model discloses a dual-station planar vertical lathe, including a worktable base 1. A rotary worktable 11 and a worktable fixing frame 12 are rotatably connected above the worktable base 1. A rotary motor 13 is installed inside the worktable base 1 to drive the rotary worktable 11 to rotate. The worktable is in a horizontal position, making it easier to clamp and correct heavy and large workpieces. No complex clamping devices are needed; the workpiece can be directly placed on the worktable and fixed, effectively improving clamping efficiency and reducing auxiliary time. It also includes a horizontal guide rail 3, with support columns 2 fixedly connected to each end of the horizontal guide rail 3. The support columns 2 are positioned behind the rotary worktable 11 to avoid affecting its normal operation. The horizontal guide rail 3 has a concave structure with a guide rail groove 31 in the middle. The guide rail groove 31 is fixed in the horizontal direction. A threaded rod 4 is provided in the guide rail groove 31. The threaded rod 4 is parallel to the horizontal guide rail 3. The threads on the outer circumference of both ends of the threaded rod 4 are symmetrically distributed. A variable frequency motor 5 is provided at one end of the horizontal guide rail 3. The motor rotation shaft 51 of the variable frequency motor 5 is fixedly connected to one end of the threaded rod 4. The variable frequency motor 5 can drive the threaded rod 4 to rotate together.

[0030] In this embodiment, a first connecting slide plate 6 and a second connecting slide plate 7 are slidably connected to the horizontal guide rail 3, and the first connecting slide plate 6 and the second connecting slide plate 7 are distributed symmetrically on the horizontal guide rail 3. Both the first connecting slide plate 6 and the second connecting slide plate 7 are fixedly connected to a height-adjustable tool holder 9. The bottom of the height-adjustable tool holder 9 is provided with a tool head 91, which is located above the rotary worktable 11. The height-adjustable tool holder 9 is used to adjust the processing height of the tool head 91. A slide plate connecting block 72 is fixedly connected to the inner side of the second connecting slide plate 7. The slide plate connecting block 72 extends into the guide rail groove 31. The center of the slide plate connecting block 72 is provided with an internal threaded through hole 73 that matches the threaded rod 4. The slide plate connecting block 72 is sleeved on the outer periphery of the threaded rod 4. When the variable frequency motor 5 rotates, the threaded rod 4 is simultaneously driven to rotate, and the slide plate connecting block 72 moves horizontally along the thread direction under the thrust of the thread. The inner side of the first connecting slide 6 is fixedly connected to a cooperating drive device 61, which connects and controls the first connecting slide 6 to move horizontally together with the rotation of the threaded rod 4. The cooperating drive device 61 can realize two states: following and stopping, thereby realizing the conversion of different working modes of the dual-station planar vertical lathe.

[0031] In this embodiment, the cooperative drive device 61 includes a sliding vane connecting cylinder 611, which has a hollow structure, allowing the threaded rod 4 to pass through the sliding vane connecting cylinder 611 without contact. An adjusting ring 616 is fixedly connected to one side of the sliding vane connecting cylinder 611. The outer periphery of one side of the adjusting ring 616 is provided with an external thread 612 and a matching threaded ring 613. A connecting ring 614 is fixedly connected to one side of the adjusting ring 616. At least four "T"-shaped grooves 6141, all pointing towards the center of the ring, are evenly distributed on the outer surface of the connecting ring 614. The cooperative drive device 61 also includes four fan-shaped truncated cones 615. When the four fan-shaped truncated cones 615 converge towards the center, they form a hollow truncated cone shape. The top of each fan-shaped truncated cone 615 is provided with a "T"-shaped protrusion 6154 corresponding to the "T"-shaped groove 6141, ensuring that each fan-shaped truncated cone 615 can move towards the center of the ring along the "T"-shaped groove 6141. Each of the fan-shaped cones 615 has an internal thread 6152 on its inner arc surface that matches the threaded rod 4. Each pair of adjacent fan-shaped cones 615 has two corresponding spring grooves 6151 on their sides, and a spring 6153 is fixedly connected between each pair of corresponding spring grooves 6151. During operation, when the co-drive device 61 needs to move along with the rotation of the threaded rod 4, the threaded ring 613 is rotated to move towards one side of the fan-shaped cones 615 until it contacts the four fan-shaped cones 615. The threaded ring 613 is then rotated to press against the conical surface formed by the four fan-shaped cones 615, simultaneously pushing the fan-shaped cones 615 along the "T"-shaped groove 6141 on the connecting ring 614 towards the center of the ring until the internal thread 6152 on the inner arc surface of the fan-shaped cone 615 contacts and engages with the threaded rod 4. At this point, the co-drive device 61 can move along with the rotation of the threaded rod 4. If the cooperating drive device 61 is not under the rotation control of the threaded rod 4, the threaded ring 613 is rotated in the opposite direction to release it from the pressure on the four sector cones 615. At this time, the springs 6153 between the four sector cones 615 move towards the outer edge of the connecting ring 614 under the action of elastic force, and the internal threads 6152 on the inner side of the arc surface of the sector cones 615 move away from the threaded rod 4, so that the cooperating drive device 61 can be released from the rotation control of the threaded rod 4.

[0032] In this embodiment, as Figure 1 , 7As shown in Figure 8, each end edge and the middle of the horizontal guide rail 3 is provided with a threaded rod mounting bracket 32. Each threaded rod mounting bracket 32 ​​has a bearing 33 in the middle, and the threaded rod 4 is fixedly connected to the inner ring of the bearing 33. The bearings 33 in the three threaded rod mounting brackets 32 can stably fix the threaded rod 4 in the horizontal guide rail 3, avoiding vibration and shaking at the end when the variable frequency motor 5 drives it to rotate, thus affecting the smoothness of the movement of the first connecting slide 6 and the second connecting slide 7. The two sides of the horizontal guide rail 3 have vertically extending slide bars 35. The two sides of the first connecting slide 6 and the second connecting slide 7 are provided with sliding grooves 71 that match the slide bars 35, and the first connecting slide 6 and the second connecting slide 7 can move horizontally along the slide bars 35. The slide bar 35 of the horizontal guide rail 3 can cooperate with the sliding groove 71 on the first connecting slide 6 and the second connecting slide 7 to further stably install the first connecting slide 6 and the second connecting slide 7 on the horizontal guide rail 3 and provide a certain support, thereby increasing the stability of the first connecting slide 6 and the second connecting slide 7 during the movement process, and thus improving the stability of the tool holder during cutting.

[0033] This invention utilizes a variable frequency motor to drive a threaded rod with symmetrically distributed threads at both ends, enabling horizontal displacement of a dual-station planar vertical lathe with a single variable frequency motor. This saves on production costs and reduces the number of operating devices, thereby lowering energy consumption and reducing production costs. The invention also features a co-drive device located inside the first connecting slide. By rotating the threaded ring, four sector-shaped cones are compressed, causing them to retract inward until they stably contact the threaded rod, thus achieving simultaneous dual-station operation. Conversely, by rotating the threaded ring in the opposite direction until it releases the compression from the four sector-shaped cones, the cones expand outward under the spring force, disengaging from the threaded rod, thus achieving single-station operation. This invention solves the technical problem of lack of flexibility and inability to switch between single and dual-column operation in dual-station planar vertical lathes, achieving a controllable switchable operation mode between single and dual columns, improving the flexibility of dual-station planar vertical lathes, and broadening their application range.

[0034] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
