Description

Technical Field

[0001] This utility model relates to the technical field of milling cutter processing equipment, and in particular to an inverted milling machine. Background Technology

[0002] Traditional milling equipment commonly employs a "top-mounted" layout, where the milling cutter spindle is positioned above the workpiece and the fixture platform below. In this layout, loading and unloading milling operations must be performed sequentially at the same station. During loading and unloading operations, milling must be completely stopped, waiting for the material change before restarting. This working mode results in significant unproductive downtime, especially when handling complex workpieces, leading to particularly low efficiency. Furthermore, the top-down machining motion in traditional layouts causes chips to accumulate on the workpiece surface and fixture, negatively impacting machining accuracy and surface quality. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an inverted milling machine with a simple structure that effectively improves work efficiency.

[0004] The main contents of this utility model include: a material loading module, which includes a carrier plate and a rotary drive mechanism; the carrier plate has a front and a back, and clamping components are provided on both the front and the back for clamping workpieces; the rotary drive mechanism is used to drive the carrier plate to rotate so that the front and the back alternately face the processing position; The machining module is located below the carrier plate. The machining module includes at least one milling cutter unit, a lifting drive module for driving the milling cutter unit to move up and down along the Z-axis, and a traversing drive module for driving the milling cutter unit to move laterally along the Y-axis. The lateral drive module is configured to drive the milling cutter unit to move between a machining position and a clearance position. In the machining position, the milling cutter unit is located directly below the carrier plate to mill the workpiece clamped on the carrier plate. In the clearance position, the milling cutter unit moves to one side of the carrier plate to avoid the rotation of the carrier plate.

[0005] Preferably, the rotary drive mechanism includes a first rotary disk and a second rotary disk connected to both sides of the carrier plate along the X direction. A rotary drive component is connected to one side of the first rotary disk to drive the first rotary disk to rotate, and a drive bracket is connected to the bottom of the first rotary disk. A disc tail seat is connected to one side of the second rotary disk, and a tail seat bracket is connected to the bottom of the disc tail seat.

[0006] Preferably, the clamping assembly includes multiple reference blocks, multiple first clamping units, and multiple second clamping units. The reference blocks are used for initial positioning of the workpiece, and the first and second clamping units are used for clamping the workpiece from different positions.

[0007] Preferably, the first clamping unit includes a support fixed on the carrier plate and a rotating pressing member disposed on one side of the support, the rotating pressing member rotatably pressing the workpiece.

[0008] Preferably, the second clamping unit includes a lifting member fixed on the carrier plate and a flipping pressing member disposed on one side of the lifting member, the flipping pressing member being able to flip and press the workpiece.

[0009] Preferably, the milling cutter unit includes a milling cutter and a milling cutter drive unit for driving the milling cutter to rotate, and the machining end of the milling cutter is arranged vertically upward.

[0010] Preferably, the machining module includes multiple milling cutter units, which are staggered to correspond to different machining positions.

[0011] Preferably, each milling cutter unit is independently provided with the lifting drive module to independently drive each milling cutter unit to move up and down along the Z-axis.

[0012] Preferably, at least two of the milling cutter units are mounted on the same lifting drive module so as to be driven by the same lifting drive module to move up and down along the Z-axis.

[0013] The beneficial effects of this invention are as follows: By adopting a flip-up double-sided carrier plate and an inverted milling cutter design, the machining and loading / unloading processes are completely parallel in time. When one side of the carrier plate is being milled from below, the operator can simultaneously perform loading / unloading operations on the other side, eliminating the waiting time for changing materials in traditional equipment and effectively improving work efficiency. During machining, the chips from the inverted milling cutter naturally fall downwards under the action of gravity, preventing them from accumulating on the workpiece or carrier plate, effectively avoiding machining quality problems caused by chip residue on the workpiece surface, and effectively improving machining accuracy.

[0015] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, this application proposes an inverted milling machine, which includes a loading module 1 and a processing module 2. Specifically, the loading module 1 is located at the top, and the processing module 2 is located at the bottom. The loading module 1 includes a carrier plate 11 and a rotary drive mechanism 12 for driving the carrier plate 11 to rotate. The carrier plate 11 has a front and a back, and clamping components 13 are provided on both the front and back for clamping workpieces. By flipping the carrier plate 11 180° so that its front and back face the processing module alternately, it is possible to load and unload materials on the front of the carrier plate 11 while milling the clamped workpieces on its back. The two processes are performed simultaneously, which can effectively reduce the waiting time of the equipment and improve work efficiency.

[0017] like Figure 1-3 As shown, the clamping assembly 13 includes multiple reference blocks 131, multiple first clamping units, and multiple second clamping units. Reference blocks 131 are used for initial positioning of the workpiece to roughly determine its initial placement. Each first clamping unit includes a support 132 fixed to the carrier plate 11 and a movable rotating pressing member 133 (e.g., a rotating pressing cylinder). The rotating pressing member 133 is located on the side of the support 132 away from the workpiece clamping area. The bottom of the workpiece is placed on the support 132, and the rotating pressing member 133 rotates around an axis and presses against the upper surface of the workpiece to perform initial clamping action on its periphery. Each second clamping unit includes a lifting member 134 and a tilting pressing member 135 (e.g., a lever cylinder). The lifting member 134 can be a lifting cylinder; the upper end of the push rod of the lifting member 134 lifts upward to provide upward support force. The tilting pressing member 135 tilts downward from the side to further stabilize and clamp the periphery of the workpiece. The positions of the first and second clamping units can be arranged according to the outer contour of the workpiece and the position to be processed, so as to adapt to workpieces with different shapes and clamping requirements and ensure stability and accuracy during the processing.

[0018] like Figure 1-2As shown, the rotary drive mechanism 12 is connected to both sides of the vehicle plate 11 in the X direction. Specifically, it includes a first rotary disk 121 connected to one side of the vehicle plate 11 in the X direction and a second rotary disk 122 connected to the other side of the vehicle plate 11 in the X direction. A rotary drive component 123 (such as a servo motor) is connected to the outer side of the first rotary disk 121, and the bottom of the rotary drive component 123 is supported by a drive bracket 124. A disc tailstock 125 is connected to the outer side of the second rotary disk 122, and the bottom of the disc tailstock 125 is supported by a tailstock bracket 126. The rotary drive component 123 drives the first rotary disk 121 to rotate, thereby driving the entire vehicle plate 11 to rotate. The disc tailstock 125 provides auxiliary support to the other side of the vehicle plate 11 to improve the stability of the vehicle plate 11 during rotation. The rotary drive mechanism 12 is erected through the drive bracket 124 and the tailstock bracket 126 to provide clearance space for the rotation of the vehicle plate 11, which can rotate 180° around the X-axis.

[0019] like Figure 1-4 As shown, the machining module 2 includes at least one milling cutter unit 21, a lifting drive module 22 for driving the milling cutter unit 21 to move up and down along the Z-axis, and a traversing drive module 23 for driving the milling cutter unit 21 to move laterally along the Y-axis. The milling cutter unit 21 includes a milling cutter 211 and a milling cutter drive component 212 (such as a servo motor). The machining end of the milling cutter 211 is vertically upward, that is, it is aligned with the workpiece on the upper carrier plate 11 in an "inverted" posture. During machining, the chips generated by the inverted milling cutter 211 fall naturally downward under the action of gravity and will not accumulate on the surface of the workpiece or the carrier plate 11, which helps to ensure the cleanliness of the machined surface and the machining quality.

[0020] like Figure 1-4 As shown, the transverse drive module 23 moves the milling cutter unit 21 from the machining position directly below the carrier plate 11 to the side clearance position. When the carrier plate 11 needs to be flipped, the milling cutter unit 21 moves first, providing sufficient space for the rotation of the carrier plate 11, avoiding interference, and ensuring the continuity and safety of the equipment operation.

[0021] like Figure 1-4 As shown, in a specific embodiment, the processing module 2 is configured with multiple milling cutter units 21. These units can be staggered to simultaneously process different positions on the workpiece. Each milling cutter unit 21 can be independently configured with a lifting drive module 22. Each milling cutter 211 can be independently lifted and lowered according to the processing depth requirements of its corresponding position, offering high flexibility and suitability for complex situations where the workpiece surface has height differences or requires different processing depths. Preferably, for multiple positions where the processing surface is on the same plane or has the same processing depth, multiple milling cutter units 21 can be mounted on the same lifting drive module 22. This simplifies the structure, reduces manufacturing costs, and ensures height consistency across multiple processing points.

[0022] All of these lifting drive modules 22 are mounted on the same traverse drive module 23, thereby achieving synchronous traverse movement of all milling cutter units 21 and ensuring consistency in machining and avoidance actions.

[0023] In a specific embodiment, the lifting drive module 22 and the traversing drive module 23 may employ servo motors and lead screw modules.

[0024] Working principle: 1. In the initial state, the front of the carrier plate 11 faces upward, and the operator clamps the workpiece from the front. At this time, the milling cutter unit 21 of the machining module 2 is in the avoidance position.

[0025] 2. Start processing: The carrier plate 11 is rotated 180° under the drive of the rotary drive component 123, so that the back of the clamped workpiece is facing down and moved to the processing position. At the same time, the empty front is facing up, ready for the next loading.

[0026] 3. Milling: The transverse drive module 23 drives the milling cutter unit 21 to the machining position directly below the carrier plate 11. Then, the lifting drive module 22 drives the milling cutter 211 to rise and perform milling on the workpiece.

[0027] 4. Parallel operation: While processing is in progress, the operator loads materials onto the front of the carrier plate 11.

[0028] 5. Cycle Preparation: After the back side machining is completed, the milling cutter unit 21 descends and is moved to a clearance position by the transverse drive module 23. Then, the carrier plate 11 rotates 180° again, turning the machined workpiece to the front side for unloading, and turning the new workpiece that was just clamped on the front side to the back side, ready to enter the next machining cycle.
