Description

Technical Field

[0001] This utility model relates to the technical field of automated drilling and milling machine for bakelite, and in particular to automated drilling and milling machine for bakelite. Background Technology

[0002] Plywood, also known as phenolic resin board, is made by gluing together multiple layers of the same or different types of wood under hot pressure. This gluing process improves its waterproof, deformation-resistant, and bending-resistant properties, while also increasing wood utilization and reducing costs. Processing often involves drilling or milling. However, due to the internal glue, the wood chips produced after cutting pose a significant health hazard (they cannot be metabolized after entering the respiratory tract and have high formaldehyde content). Traditional drilling and milling machines generally do not have wood chip handling devices. Even if they do, the suction port is usually kept at a certain distance from the processing position to avoid interfering with the high-speed rotating drill bit. However, because the high-speed rotating drill bit has high kinetic energy, the chance of wood chips flying is high. Faced with this situation, some people allow a small amount of wood chips to fly out in order to reduce costs. Others increase the power of the fan to increase the negative pressure of the suction and improve the absorption rate of wood chips. However, this method increases equipment costs and energy consumption, and the high-powered fan greatly increases noise, which is another health hazard.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] The automated drilling and milling machine for bakelite includes a three-axis machine tool, wherein the three-axis machine tool includes a slide table driven by a lead screw and a motor, bakelite is fixed on the slide table and moves therewith, and a drilling and milling motor is equipped on the Z-axis moving part of the three-axis machine tool, the drilling and milling motor drives a drill bit or a milling head to perform operations;

[0005] It also includes a follow-up chip cleaner, which is disposed on the lower end face of the drilling and milling motor and fitted outside the drill bit or milling head. The follow-up chip cleaner has a downward-opening cavity, which is connected to a suction fan through a suction hose. A negative pressure suction is formed in the cavity to clean up the wood chips generated by drilling or milling.

[0006] Preferably, the follow-up chip collector includes a sliding base sleeve and a suction guide sleeve, wherein a guide rod is fixedly provided on the suction guide sleeve, the guide rod is slidably inserted into the lower flange of the sliding base sleeve, a spring is sleeved outside the guide rod and its two ends respectively abut against the upper end face of the suction guide sleeve and the lower end face of the sliding base sleeve, and a limiting end is fixedly provided at the upper end of the guide rod. The sliding base sleeve is fixed to the lower end face of the drilling and milling motor, so that the suction guide sleeve can move up and down relative to the sliding base sleeve, which facilitates the movement of the drill bit or milling head when it is feeding downwards, and the cavity is located inside the suction guide sleeve.

[0007] Preferably, the suction guide sleeve is provided with a negative pressure suction chamber, and the side of the suction guide sleeve is provided with a threaded pipe joint. The end of the suction hose is connected to the threaded pipe joint in an airtight threaded connection, and negative pressure is generated in the negative pressure suction chamber under the action of the suction fan.

[0008] Preferably, the lower inner wall of the suction guide sleeve is a downwardly flared conical surface. This design facilitates the formation of a larger suction coverage area and better suction. Suction ports are provided at circumferential intervals on the conical surface, and the suction ports are connected to the negative pressure suction chamber.

[0009] Preferably, the lower end of the suction guide sleeve is provided with a circumferentially spaced ventilation wedge, and the ventilation wedge and the air intake are staggered. This design is highly aerodynamic, ensuring good airflow even when the suction guide sleeve is attached to bakelite. The wind pressure at the ventilation wedge impacts the wood chips on the board. Since the lower inner wall of the suction guide sleeve is constricted upwards, when air enters quickly through the narrow opening of the ventilation wedge, its kinetic energy picks up the wood chips, which are then quickly sucked away under the negative pressure difference at the air intake. This structural design effectively utilizes the kinetic energy of the wind, improving its dust collection efficiency. Compared with existing technologies, this structure is more scientific and reasonable.

[0010] The advantages and positive effects of this utility model are:

[0011] Employing a unique structural design, it is fitted around the drill bit during operation. When wood chips fly, the annular surrounding structure of the suction guide sleeve can block large wood chips. Furthermore, the design of the suction guide sleeve concentrates the airflow more near the cutting position, effectively increasing the probability of absorbing wood chips compared to existing technologies. This reduces the requirements for selecting a matching dust extraction fan.

[0012] Furthermore, the suction guide sleeve can move up and down relative to the drilling and milling motor, thus avoiding interference during the drilling process where the drill bit extends from top to bottom, while ensuring that the lower end face of the suction guide sleeve abuts against the upper end face of the bakelite.

[0021] It also includes a follow-up chip cleaner 13, which is disposed on the lower end face of the drilling and milling motor 11 and fitted outside the drill bit or milling head. The follow-up chip cleaner 13 has a downward-opening cavity, which is connected to a suction fan through a suction hose. A negative pressure suction is formed in the cavity to clean up the wood chips generated by drilling or milling.

[0022] Preferably, the follow-up chip collector 13 includes a sliding base sleeve 14 and a suction guide sleeve 17, wherein a guide slide rod 15 is fixedly provided on the suction guide sleeve 17, the guide slide rod 15 is slidably inserted into the lower flange of the sliding base sleeve 14, a spring 16 is sleeved on the outside of the guide slide rod 15 and its two ends respectively abut against the upper end face of the suction guide sleeve 17 and the lower end face of the sliding base sleeve 14, and a limiting end is fixedly provided at the upper end of the guide slide rod 15. The sliding base sleeve 14 is fixed to the lower end face of the drilling and milling motor 11, so that the suction guide sleeve 17 can move up and down relative to the sliding base sleeve 14, which facilitates the movement of the drill bit or milling head when it is feeding downwards, and the cavity is located inside the suction guide sleeve 17.

[0023] Preferably, the suction guide sleeve 17 is provided with a negative pressure suction chamber 18, and the suction guide sleeve 17 is provided with a threaded pipe joint 19 on its side. The end of the suction hose is connected to the threaded pipe joint 19 in a threaded airtight connection.

[0024] Preferably, the lower inner wall of the suction guide sleeve 17 is a downwardly flared conical surface. This design facilitates the formation of a larger suction coverage area and better suction.

[0025] Preferably, a ventilation wedge 21 is provided at an annular interval at the lower end of the suction guide sleeve 17, and the ventilation wedge 21 and the suction port 20 are staggered. This design is very aerodynamic, which can ensure good air circulation when the suction guide sleeve 17 is attached to bakelite. The wind pressure at the ventilation wedge 21 impacts the wood chips on the board. Since the inner wall of the lower end of the suction guide sleeve 17 is narrowed upward, when the air enters quickly through the narrow opening of the ventilation wedge 21, its kinetic energy rolls up the wood chips and they are quickly sucked away under the negative pressure difference at the suction port 20.
