Description

Technical field:

[0001] The utility model relates to the technical field of woodworking processing equipment, and more specifically to a woodworking router with a dust suction structure. Background technology:

[0002] Woodworking milling machine is a woodworking machine tool that uses a high-speed rotating milling cutter (see woodworking tool) to slot, tenon and process wood into a formed surface. Woodworking milling machines are divided into three types: vertical single-axis woodworking milling machines, wood mold milling machines and router milling machines.

[0003] In the existing woodworking milling machines, the processing tool (milling cutter) is above the top surface of the top plate of the frame, and the top surface of the milling machine is a horizontal plane, and there are no other mechanisms, so that the operator can bring the material to be milled close to the processing tool for processing. A large amount of cutting powder will be generated during the processing, which will float in the air and affect the surrounding air pollution. At the same time, it will fall to the ground and accumulate, and will also pollute the ground environment. Therefore, dust collection is generally installed in the entire operating workshop to vacuum the air, but its effect is limited. For the operator who directly operates the machine, it is still easy to absorb the dust. Generally, the operator can only wear a mask and other equipment to operate, but there is too much dust, and the mask needs to be replaced in time after a certain period of use, and the effect is not ideal. Utility model content:

[0004] The purpose of the utility model is to address the deficiencies of the prior art and to provide a woodworking router with a dust suction structure, which has a fan-shaped block on the top plate of the router body that can rotate along the milling tool, so that it can meet the needs of different wood processing. The chips and dust generated by the processing can be adsorbed and processed through the adsorption holes of the fan-shaped block to reduce the impact on the surrounding space. Moreover, the fan-shaped block can be rotated so that it will not block the rotation operation along the milling tool during wood processing.

[0005] The technical solutions of the utility model are as follows:

[0006] A woodworking router with a dust suction structure comprises a router body, a central through hole is formed in the middle of a top plate of the router body, an upper part of a main shaft extends out of the central through hole and a milling tool is fixed thereon, an annular groove is formed on the top surface of the top plate of the router body along the outer side of the central through hole, a plurality of annular guide rails are installed on the bottom surface of the annular groove, a sector block is located on one side of the milling tool, an arc-shaped connecting plate is fixed on the bottom surface of the sector block, a plurality of plastic elastic guide blocks are fixed on the bottom surface of the arc-shaped connecting plate, an arc-shaped groove is formed in the middle of the bottom surface of the plastic elastic guide block, and the annular guide rails are nested in the corresponding arc-shaped grooves;

[0007] The fan-shaped block has an inner cavity formed inside, and a plurality of adsorption holes are formed on the inner wall of the fan-shaped block facing the milling cutter, the adsorption holes are connected to the inner cavity, and the middle of the outer wall of the fan-shaped block is connected to a suction connector, which is connected to the inner cavity.

[0008] A plurality of vertical through holes extending downward are formed on the bottom edge of the annular groove.

[0009] An annular shell is fixed to the bottom surface of the top plate of the milling machine body, the bottom ends of all vertical through holes are communicated with the inner cavity of the annular shell, and the side wall of the annular shell is connected with a second air suction connector.

[0010] The beneficial effects of the utility model are:

[0011] The fan-shaped block on the top plate of the router body can rotate along the milling tool, so that it can meet the needs of different wood processing. The chips and dust generated by the processing can be adsorbed and processed through the adsorption holes of the fan-shaped block to reduce the impact on the surrounding space. Moreover, the fan-shaped block can be rotated so that it will not block the rotation operation along the milling tool during wood processing. Description of the drawings:

[0015] Example: See Figures 1 to 3 As shown, a woodworking router with a dust suction structure includes a router body 10, a center through hole is formed in the middle of the top plate of the router body 10, the upper part of the main shaft 11 of the router body 10 extends out of the center through hole and is fixed with a milling tool 12, and the milling tool 12 is located above the top surface of the top plate of the router body 10. This structure is the same as the existing publicly available router structure that can be directly purchased, and will not be described in detail here.

[0016] The top plate of the milling machine body 10 is formed with an annular groove 13 on the top surface along the outer side of the central through hole, and a plurality of annular guide rails 14 (two annular guide rails 14 in this embodiment) are installed on the bottom surface of the annular groove 13. The top of the annular guide rail 14 does not extend out of the top of the annular groove 13. The cross section of the annular guide rail 14 is circular, and a plurality of lower legs are fixed on the bottom surface of the annular groove 13. The fan-shaped block 20 is located at one end of the milling tool 12. On the side, an arc-shaped connecting plate 21 is fixed to the bottom surface of the sector block 20, and a plurality of plastic elastic guide blocks 22 (which are polytetrafluoroethylene self-lubricating blocks) are fixed to the bottom surface of the arc-shaped connecting plate 21. An arc-shaped groove extending upward is formed in the middle of the bottom surface of the plastic elastic guide block 22, and an arc-shaped groove with a circular cross-section is formed on the top surface of the arc-shaped groove. The annular guide rail 14 is inserted into the arc-shaped groove, and the lower support leg is inserted into the arc-shaped groove; so that the plastic elastic guide block 22 can move along the annular guide rail 14.

[0017] An inner cavity is formed inside the fan-shaped block 20, and a plurality of adsorption holes 23 are formed on the inner wall of the fan-shaped block 20 facing the milling cutter 12, and the adsorption holes 23 are communicated with the inner cavity. An air suction connector 24 is fixed in the middle of the outer wall of the fan-shaped block 20, and the air suction connector 24 is communicated with a through hole on a side wall of the inner cavity, and the air suction connector 24 is communicated with the inner cavity.

[0018] The suction connector 24 is connected to an external dust collection device through a connecting pipe, and the dust collection device is operated to achieve constant adsorption. The dust collection device can adopt existing industrial known vacuum cleaners and other equipment. It is a known structure and will not be described in detail here.

[0019] Furthermore, a plurality of vertical through holes 1 extending downward are formed on the bottom edge of the annular groove 13 .

[0020] Furthermore, an annular shell 30 is fixed to the bottom surface of the top plate of the milling machine body 10 , the bottom ends of all vertical through holes 1 are connected to the inner cavity of the annular shell 30 , and a second air suction connector 31 is connected to the side wall of the annular shell 30 .

[0021] Furthermore, the annular housing 30 is formed by splicing two semi-arc housings, which facilitates disassembly and installation.

[0022] The second air suction connector 31 of this embodiment is also connected to the external dust suction equipment through the connecting pipe. The dust suction equipment is operated to achieve constant adsorption. The dust suction equipment can adopt existing industrial well-known vacuum cleaners and other equipment. It is a well-known structure and will not be described in detail here.

[0023] When this embodiment is in use, it can place the wood on the top plate of the milling machine body 10, and then move the part that needs to be cut close to the milling tool 12 for milling. During the processing, the waste chips or dust will fall into the annular groove 13, enter the annular shell 30 through the vertical through hole 1 and be sucked away, and some will be adsorbed through the adsorption through hole 23 of the fan-shaped block 20, enter the inner cavity of the fan-shaped block 20, and finally be sucked away for processing, which greatly reduces the surrounding dust and makes it difficult for operators to adsorb dust. In particular, the use time of the mask they wear can be increased, which greatly reduces the number of dust particles around, and the effect is good.

[0024] Moreover, when in use, when the wood rests on the extension plates extending from the outer walls at both ends of the sector block 20, the sector block 20 can be rotated along the annular groove 13 without blocking the wood processing. The wood can be processed along the rotation direction of the milling tool 12, and the use effect is good.
