[0002] In the processing of wooden furniture, the edges and corners need to be rounded. Rounding is generally done using a milling cutter. Most existing milling cutter devices rely on manual measurement and cutting or use complex mechanical equipment for measurement, cutting, and fabrication. Manual fabrication suffers from low precision and low production efficiency. To address this, Chinese Patent Publication No. CN204687003U discloses a milling cutter device for rounding the edges of wooden furniture. This structure includes a blade, a fastener, and a lifting rod. The blade has an arc-shaped cutting edge and is fixed to the furniture by the fastener. On the aforementioned lifting rod, one end of the lifting rod passes through the through groove and is connected to the output end of the motor, while the other end of the lifting rod is a free end; for example, Chinese Patent Publication No. CN104742213B discloses a device for making antique-style furniture, which includes a wooden tenon processing device and a rounded corner trimming milling cutter device. The rounded corner trimming milling cutter device is used to trim the sharp corners of the wood; the above two structures can improve processing efficiency, but when the existing milling cutter device is working, it is necessary to actively adjust the tilt angle between the board and the milling cutter head, and it is not possible to perform standardized rounded corner processing on the corners of the board. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a rounded corner milling cutter device for wooden furniture, which can perform standardized rounded corner processing on the corners of boards with high processing efficiency.

[0004] This utility model relates to a milling cutter device for rounding corners of wooden furniture, comprising: A milling cutter support, which is fixed to the side of the machining table; A rotary worktable, which is fixed to the top surface of the milling cutter support and is located on the side away from the machining table; A first electric slide is fixed to the rotating surface of a rotary worktable; a concave bracket is connected across the top of the first electric slide, the bracket is fixed to the slider of the first electric slide, and a guide rod is movably inserted through the bracket outside the first electric slide, with both ends of the guide rod fixed to a guide seat; An outer support arm, which is fixed to the outside of the mounting base by bolts; A lifting electric slide, wherein the lifting electric slide is fixed to the end of the outer support arm; A rounded corner swing unit, wherein the rounded corner swing unit is fixed on the slider of the lifting electric slide table; The milling cutter unit includes a front support, which is fixed to the swing end of the rounded corner swing unit; a cutter holder is fixed on the front support, a milling cutter is rotatably mounted on the cutter holder, and a milling cutter motor that is rotatably connected to the milling cutter is fixed on the front support.

[0005] When the rounded corner milling cutter device for wooden furniture is in operation, the rotary table can be adjusted according to the requirements of milling rounded corners at the ends of a batch of wooden profiles. The linear sliding direction of the first electric slide is aligned with the starting position of the rounded corner to be processed. Then, the wooden profile to be processed is placed on the processing table and locked. Next, the first electric slide is controlled to move, and the lifting electric slide drives the outer support arm to slide, thereby synchronously driving the rounded corner swing unit to slide synchronously, so that the milling cutter unit moves towards the processing position at the end of the wooden profile. After reaching the position, the first electric slide stops, the milling cutter motor starts, and drives the milling cutter to rotate synchronously at high speed. At the same time, the rounded corner swing unit synchronously drives the milling cutter to rotate and swing, realizing rapid rounded corner processing at the end of the wooden profile. After processing is completed, the rounded corner swing unit and the milling cutter motor stop, and the first electric slide moves backward to wait for a new wooden profile to be processed to be placed on the processing table.

[0006] Furthermore, the rounded corner swing unit includes a swing fixing seat fixed on the slider of the lifting electric slide table. A swing reducer assembly is fixed on the swing fixing seat. A disc base is selectively fixed on the swing reducer assembly. A semi-cylindrical slot is opened at the upper front end of the disc base. The front support is fixed to the front side of the slot. When the milling cutter unit performs rounded corner processing, the rounded corner swing unit is opened synchronously. The disc base is driven to rotate by a set angle through the swing reducer assembly. The rotation angle can be positioned by the rotary encoder built into the swing reducer assembly. When the disc base rotates, it can synchronously drive the front support on the slot to rotate and swing. When rotating and swinging, the milling cutter rotates synchronously, which can perform standardized rounded corner processing on the edges and corners of furniture profiles.

[0007] Furthermore, a pressure transmitter is fitted into the slot; a hole is formed outside the pressure transmitter in the slot, and a threaded hole is formed inside the hole. An adjusting bolt is movably fitted on the front support, and the adjusting bolt is screwed into the threaded hole. A spring body is provided inside the adjusting bolt and the hole. Under normal conditions, a gap is provided between the front support and the slot due to the action of the spring body. When the milling cutter unit abuts against the fillet to be processed, the spring body is compressed. At this time, the front support applies pressure to the pressure transmitter. After the pressure transmitter obtains the set pressure value, the pressure transmitter triggers the first electric slide to stop through the controller of the whole machine and triggers the milling cutter unit to open, realizing the rounding of the furniture corner.

[0008] Furthermore, a backing plate is fixed to the side of the processing table, and a profile end limiting block is provided at the front end of the table; the side of the furniture profile is attached to the backing plate, and the furniture profile is pushed forward so that the furniture profile abuts against the profile end limiting block, which can press the furniture profile firmly in place, and then the rounded corners can be processed by the milling cutter unit.

[0009] Furthermore, the front end of the table is provided with multiple dovetail grooves spaced apart, and the bottom surface of the inner side of the dovetail grooves is provided with locking teeth. The profile end limiting block is provided with multiple countersunk holes, and multiple tightening bolts are screwed into the countersunk holes. The tightening bolts are movably engaged with the locking teeth. The profile end limiting block can slide in the dovetail grooves, which can adjust the gap between the profile end limiting block and the end of the table. When the furniture profile is placed on the table, the middle part of the end face of the furniture profile abuts against the profile end limiting block, and the side of the furniture profile fits against the backing plate, so that the end face of the furniture profile is in a hollow state, which facilitates the milling cutter device to perform rounding processing on the hollow end.

[0010] Furthermore, the milling cutter is an I-shaped grinding wheel with a sloping top and bottom on the inner side; by oscillating and grinding the corners of the wood with the grinding wheel, the corners of the wood can be quickly rounded.

[0011] Compared with the prior art, the rounded corner milling cutter device for wooden furniture of this utility model can quickly position the board through the backing plate and the end limiting block of the profile, and the positioning position is standardized. The milling cutter processing position and the board processing position can be accurately positioned, so that the corners of the board can be processed in a standardized manner. During processing, there is no need to repeatedly adjust the tilt angle between the board and the milling cutter, and the rounded corner processing efficiency of wooden furniture is high.
