Description

Technical Field

[0001] The invention belongs to the technical field of furniture slotting, and in particular relates to a slotting vertical milling device for producing furniture. Background Art

[0002] Steel furniture is more durable due to its material properties and is widely used in various places. Steel pipe connectors are needed in the assembly process of steel furniture to support the entire steel furniture. The production process of steel furniture has many processes, and grooving of steel pipe connectors is one of the process steps. Vertical milling machines are needed in the grooving process.

[0003] In the prior art, a general vertical milling machine first clamps and fixes the steel pipe connector on the vertical milling machine, and drives the groove milling cutter to gradually move downward while controlling the rotation of the groove milling cutter, thereby completing the through-grooving of the steel pipe connector by the groove milling cutter. After the groove milling is completed, the steel pipe connector needs to be released from the clamping, and then a steel pipe connector to be grooved is re-clamped for another groove milling process.

[0004] However, the above-mentioned slotting method completely relies on the rotation and downward movement of the slotting cutter to complete the through slotting of the steel pipe connector. During the slotting process, the rotation and downward movement depth of the slotting cutter needs to be ensured. When the rotation and downward movement depth of the slotting cutter is insufficient, the steel pipe connector cannot be completely penetrated. At the same time, the efficient collection of the milling metal debris cannot be achieved during the slotting process. To this end, we provide a slotting vertical milling device for furniture production to solve the above-mentioned problems. Summary of the invention

[0014] The present invention has the following beneficial effects: 1. When the lifting control motor is started to control the bidirectional screw to rotate forwardly, the thread cooperation between the bidirectional screw and the corresponding ear plate is used to drive the upper and lower slotting assemblies to approach each other until the curved surface sealing covers on the upper and lower slotting assemblies are just fitted on the outer wall of the metal pipe. As the bidirectional screw continues to rotate forwardly, the sharp ends of the upper and lower slotting cutters are also pressed against the outer wall of the metal pipe. Subsequently, the bidirectional screw is continued to be controlled to rotate forwardly by the lifting control motor. At the same time, the slotting control motor is started to control the rotation of the slotting cutter. In the process of controlling the upper and lower annular mounting frames to approach each other again, the synchronous rotation of the upper and lower slotting cutters is used to gradually realize the slotting processing of the metal pipe until the sharp end of the slotting cutter drills through the outer wall of the metal pipe. At this time, the slotting processing of the metal pipe is completed. By using this slotting method, it is not necessary to ensure that the slotting cutter penetrates a deeper distance to complete the through slotting. While improving the slotting efficiency, the deflection of the metal pipe during the slotting process can be avoided by double-point slotting, which is helpful to improve the quality of the slotting processing of the metal pipe.

[0015] 2. The present invention controls the bidirectional screw to rotate in opposite directions through a lifting control motor, so that the upper and lower annular mounting frames gradually move away from each other until each annular mounting frame returns to the position where the curved sealed cover just fits the outer wall of the metal pipe fitting. At this time, each elastic element returns to its initial state. During this process, the pressure value detected by the second pressure sensor gradually decreases, and the sharp end of the milling cutter retracts into the corresponding vertical chip collecting barrel. At this time, the slot hole generated after milling is connected to the vertical chip collecting barrel, and the air flow input by the first guide pipe enters the vertical chip collecting barrel. The air flow entering the vertical chip collecting barrel blows the metal debris remaining in the vertical chip collecting barrel into the metal pipe fitting, thereby realizing the airflow sweeping and collection of the metal debris generated in the milling process.

[0016] The two-way screw is then controlled by the lifting and lowering motor to rotate forward until the curved sealing covers on the upper and lower milling groove assemblies just fit on the outer wall of the metal pipe. Then, the electromagnet is controlled to be energized and magnetized again so that the propulsion gear moves upward and fits on the bottom of the positioning plate. The two-way screw is controlled to rotate in the opposite direction again so that the upper and lower milling groove assemblies continue to move away from each other. In this process, the rotation of the propulsion gear is used to drive the horizontal gear seat to move horizontally, thereby realizing that the entire airflow guiding mechanism moves the metal pipe to the front end of the vertical milling control frame, and then the clamped metal pipe is pushed forward a certain distance again, thereby realizing the milling groove processing at the next position.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The slot milling component includes a slot milling cutter 101, and a vertical chip collecting barrel 102 is slidably sleeved on the slot milling cutter 101. A curved surface sealing cover 103 is fixedly arranged at one end of the vertical chip collecting barrel 102. The inner wall of the curved surface sealing cover 103 is provided with a slot milling opening connected to the corresponding vertical chip collecting barrel 102. The diameter of the slot milling opening is larger than the diameter of the slot milling cutter 101, which can ensure that the metal debris generated during the slot milling process enters the metal pipe 3 along the slot milling opening. The metal pipe 3 and the curved surface sealing covers 103 on both sides thereof are in contact with each other. During the slot milling process, the curved surface sealing cover 103 is tightly attached to the side surface of the metal pipe 3, which can effectively prevent the metal debris from falling to the outside of the metal pipe 3. The upper air outlet of the first air guide component is connected to the corresponding vertical chip collecting barrel 102, and the lower air outlet of the first air guide component is connected to the corresponding vertical chip collecting barrel 102. The first air guide component, the vertical chip collecting barrel 102, the metal pipe 3 and the second air guide component are connected in series in sequence to form an airflow chip collecting channel. After the milling groove is completed, the metal debris remaining in the vertical chip collecting barrel 102 during the milling groove process can be discharged and collected by the air flow flowing through the airflow chip collecting channel.

[0031] In this embodiment of the present invention, the vertical milling control mechanism 1 also includes a vertical milling control frame 104, a connecting member 105 is fixedly arranged on one side of the vertical milling control frame 104, and the connecting member 105 is fixedly installed on the external frame. A vertical guide rod 106 and a bidirectional screw 107 are respectively arranged inside the vertical milling control frame 104, the vertical guide rod 106 is fixedly arranged inside the vertical milling control frame 104, and the bidirectional screw 107 is rotatably arranged inside the vertical milling control frame 104, and the vertical guide rod 106 and the bidirectional screw 107 are arranged oppositely, and the output end of the lifting control motor 108 fixedly installed on the top of the vertical milling control frame 104 is connected to the bidirectional screw 107; The milling slot assembly also includes an annular mounting frame 109 arranged inside the vertical milling control frame 104, a milling slot control motor 110 is fixedly installed inside the annular mounting frame 109, the output end of the milling slot control motor 110 is fixedly connected to the corresponding milling slot cutter 101, the curved surface sealing cover 103 is connected to the corresponding annular mounting frame 109 through an elastic element 111, ear plates are fixedly arranged on opposite sides of the annular mounting frame 109, the vertical guide rod 106 is slidably connected to the corresponding ear plate, and the bidirectional screw 107 is connected to the corresponding ear plate. Plate thread cooperation; when the lifting control motor 108 is started to control the bidirectional screw 107 to rotate forward, the thread cooperation between the bidirectional screw 107 and the corresponding ear plate is utilized to drive the upper and lower milling groove assemblies closer to each other until the curved surface sealing covers 103 on the upper and lower milling groove assemblies just fit against the outer wall of the metal pipe 3. As the bidirectional screw 107 continues to rotate forward, the sharp ends of the upper and lower milling groove cutters 101 are also pressed against the outer wall of the metal pipe 3, thereby completing the preparation work before milling grooves.

[0032] Subsequently, the bidirectional screw 107 is controlled to rotate forwardly through the lifting control motor 108. At the same time, the milling control motor 110 is started to control the rotation of the milling cutter 101. In the process of controlling the upper and lower annular mounting frames 109 to approach each other again, the synchronous rotation of the upper and lower milling cutters 101 is used to gradually realize the milling of the metal pipe 3 until the sharp end of the milling cutter 101 drills through the outer wall of the metal pipe 3. At this time, the milling of the metal pipe 3 is completed. This milling method does not require the milling cutter 101 to penetrate a deeper distance to complete the through grooving. While improving the milling efficiency, the double-point milling can avoid the deflection of the metal pipe 3 during the milling process, which helps to improve the quality of the milling of the metal pipe 3.

[0033] In this embodiment of the present invention, a first guide tube 112 communicating with the inner cavity of the vertical chip collecting barrel 102 is fixedly provided on the peripheral side of the vertical chip collecting barrel 102, a pressure trigger disk 113 is connected to the bottom of the annular mounting frame 109 located below through a support rod, a first pressure sensor adapted to the position of the pressure trigger disk 113 is installed at the bottom of the vertical milling control frame 104, a second pressure sensor is installed on the inner wall of the curved surface sealing cover 103, an electromagnet 114 coaxial with the bidirectional screw 107 is installed at the bottom of the vertical milling control frame 104, a first connecting frame 115 (the first connecting frame 115 is configured as a retractable structure) is fixedly provided on the side of the annular mounting frame 109 away from the first guide tube 112, an arc-shaped support plate 116 is fixedly provided at one end of the first connecting frame 115, a positioning disk 117 close to the electromagnet 114 is fixedly provided on the peripheral side of the bidirectional screw 107, and a limited position guide portion 118 is fixedly provided on the side of the vertical milling control frame 104 relative to the connecting member 105.

[0034] In the initial state, the upper and lower groove milling assemblies are in positions far away from each other, and the upper and lower arc-shaped support plates 116 are also in positions far away from each other. After the metal pipe 3 is clamped and fixed between the first guide assembly and the second guide assembly, the bidirectional screw 107 is controlled to rotate forward so that the upper and lower groove milling assemblies are close to each other until the curved sealed covers 103 on the upper and lower groove milling assemblies just fit against the outer wall of the metal pipe 3, and the upper and lower arc-shaped support plates 116 also synchronously fit against the outer wall of the metal pipe 3. At this time, the controller receives the pressure signal transmitted from the second pressure sensor, and continues to control the bidirectional screw 107 to rotate forward so that the rotating groove milling cutter 101 completes the groove milling processing of the metal pipe 3. During this process, the elastic element 111 is gradually compressed, so that the curved sealed cover 103 fits more closely with the outer wall of the metal pipe 3, and the pressure value detected by the second pressure sensor gradually increases.

[0035] Subsequently, the bidirectional screw 107 is controlled by the lifting control motor 108 to start rotating in the opposite direction, so that the upper and lower annular mounting frames 109 gradually move away from each other until each annular mounting frame 109 returns to the position where the curved sealed cover 103 just fits the outer wall of the metal pipe 3. At this time, each elastic element 111 returns to its initial state (that is, the elastic element 111 returns to its original length). During this process, the pressure value detected by the second pressure sensor gradually decreases, and the sharp end of the milling cutter 101 retracts into the corresponding vertical chip collecting barrel 102. At this time, the slot hole generated after milling is connected to the vertical chip collecting barrel 102, and the air flow input by the first guide pipe 112 enters the vertical chip collecting barrel 102. The air flow entering the vertical chip collecting barrel 102 blows the metal debris remaining in the vertical chip collecting barrel 102 into the metal pipe 3, thereby realizing the airflow sweeping and collection of the metal debris generated during the milling process.

The air flow entering the vertical chip collecting barrel 102 blows the metal debris inside it into the metal pipe 3, and under the action of the air flow, the metal debris is transported to the rear end of the metal pipe 3.

In the process of transporting metal debris to the rear end of the metal pipe 3 under the action of the air flow, the air flow mixed with the metal debris enters the second guide plate 206 through the flow pipe 208, and then enters the air outlet duct 207 from the second guide plate 206. The air outlet duct 207 is connected to an external chip collection device through a connecting pipe, and the air flow discharged through the air outlet duct 207 realizes efficient collection of metal debris.

Under the action of the threaded cooperation between the control shaft 212 and the positioning seat 209, the positioning seat 209 is driven to slide along the horizontal support frame 210, thereby adjusting the horizontal distance between the first guide plate 201 and the second guide plate 206. Through this structure, after one end of the metal pipe 3 is pressed against the elastic material on the surface of the first guide plate 201, the second guide plate 206 is gradually driven close to the metal pipe 3 until the elastic material on the surface of the second guide plate 206 is tightly pressed against the other end of the metal pipe 3, thereby the metal pipe 3 can be tightly clamped between the first guide plate 201 and the second guide plate 206.
