Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing and cutting, and in particular to a mechanical processing and cutting device. Background Art

[0002] Mechanical cutting is a type of mechanical processing that can achieve various processing effects on objects. Among them, the cutting methods are divided into knife cutting, wire cutting and laser cutting.

[0003] In the production process of some furniture, the wooden boards need to be cut and initially shaped. For those thicker boards, they are usually cut with a pattern saw. When cutting with a pattern saw, the wood needs to be cut by reciprocating up and down. The pattern saw is composed of a saw blade and a number of evenly distributed saw teeth. The pattern saw needs to be kept taut during cutting. Generally speaking, it has high rigidity and a certain width. This makes the pattern saw encounter the following problems when cutting: 1. Some board designs require more delicate curves, but the pattern saw is generally unable to cut curves with a smaller radius due to its own certain width. Some of them need to be cut and trimmed manually later, which increases the processing cycle and has certain limitations; 2. Some patterns require not only edge cutting, but also internal hollowing. When cutting, the pattern saw needs to start cutting from the edge of the wood and cannot directly hollow out the inside of the wood. It requires subsequent manual hollowing, which is inefficient.

The driving blocks correspond to the driving grooves one by one and are inserted into the corresponding driving grooves. The driving blocks conflict with the driving grooves, and the No. 1 motor 7 is placed on the top by driving the motor to rotate. When the clamping column 13 is separated from the rotating rotary cutting line 11, the No. 1 motor 7 and the two-way cylinder control can be used to control the drill bit 9 to punch holes in the cutting part of the wood first, so as to avoid cutting from the edge of the wood and causing waste of wood. After punching, the drill bit 9 is inserted into the slot 1301 and enters the locking slot 901 with the limiting clamping tooth 1303, so that the drill bit 9 can be fixed to the rotating rotary cutting line 11. At this time, the No. 2 motor 8 is placed on the top by driving the motor to rotate.Start the No. 1 motor 7 and the No. 2 motor 8 synchronously. The rotation speed of the No. 1 motor 7 and the No. 2 motor 8 are the same in structure and rotation speed, so that the rotation speed of the drill bit 9 and the rotating rotary cutting wire 11 are kept synchronous. The rotating rotary cutting wire 11 rotates and rubs on the hole wall after punching, which can produce a cutting effect on the wood, increase the cutting efficiency of the wood, reduce the roughness of the cut surface of the wood after cutting to a certain extent, and cut along the inner wall of the punched hole at the same time. Since the diameter of the rotating cutting wire 11 is small, the inside of the board can be hollowed out to a certain extent.

[0027] The inner wall of the clamping shaft 10 is provided with three clamping grooves 1001 evenly distributed along the inner wall thereof, and a plurality of evenly distributed clamping teeth 1002 are fixedly installed in the three clamping grooves 1001. The outer wall of the plug-in shaft 12 is provided with three evenly distributed extrusion grooves 1201, and the extrusion grooves 1201 correspond to the clamping grooves 1001 one by one. A rack 1202 is slidably connected in the extrusion groove 1201, and the rack 1202 extends out of the extrusion groove 1201 and is inserted into the corresponding clamping groove 1001, and the rack 1202 is meshed with the clamping teeth 1002. The meshing of the clamping teeth 1002 with the rack 1202 prevents the plug-in shaft 12 from being separated from the clamping shaft 10.

[0028] Three evenly distributed centrifugal grooves 1003 are provided on the outer wall of the clamping shaft 10, and the bottom of the centrifugal groove passes through the lower surface of the clamping shaft 10. A centrifugal slider 1004 is slidably connected in the centrifugal groove 1003. Three symmetrically arranged telescopic blocks 14 are hinged at the bottom of the clamping shaft 10, and the telescopic blocks 14 correspond to the centrifugal sliders 1004 one by one. One end of the telescopic block 14 close to the corresponding centrifugal slider 1004 is hinged to the bottom of the centrifugal slider 1004. Two mutually symmetrical springs are arranged in the centrifugal groove 1003, and the clamping shaft 10 is driven to rotate by the rotation of the No. 2 motor 8. Under the action of centrifugal force, the centrifugal slider 1004 will move to the other end of the centrifugal groove 1003, and cooperate with the telescopic block 14, so that the end of the telescopic block 14 away from the centrifugal slider 1004 will touch the bottom of the plug-in shaft 12 and squeeze the plug-in shaft 12, thereby avoiding the situation where the rotating cutting line 11 becomes loose due to wear during the rotary cutting process.

[0029] A number of evenly distributed fixing rods 15 are fixedly installed at the bottom of the clamping shaft 10, and a triangular-structured No. 1 blade 16 is fixedly installed at the bottom of the fixing rod 15. There are six fixing rods 15. Under the action of the rotation of the clamping shaft 10, the No. 1 blade 16 will rotate synchronously and generate a certain airflow, which can blow away the wood chips generated by cutting wood to a certain extent.

[0030] A triangular blade slot 1601 is provided at one end of the blade 16 close to the rotating cutting line 11, and a No. 2 blade 17 is slidably connected in the blade slot 1601. The blade slot 1601 extends out of the end of the No. 2 blade 17 away from the blade slot 1601. An auxiliary push rod 18 is fixedly installed on the outer wall of the telescopic block 14, and the auxiliary push rod 18 runs through the telescopic block 14. A linkage rod 19 is fixedly installed on the top of the No. 1 blade 16. The supporting shaft rotates to drive the telescopic block 14 to expand, so that the auxiliary push rod 18 contacts the linkage rod 19, so that the No. 2 blade 17 is close to the rotating cutting line 11, and the No. 1 blade 16 cooperates with the No. 2 blade 17 to increase the airflow.

[0031] The outer side of the clamping shaft 10 is provided with a funnel-shaped wind catcher 20, which is fixedly mounted on the movable arm through a bracket, and the rotating cutting line 11 passes through the wind catcher 20. A filter tube is provided on the outer wall of the wind catcher 20 for filtering wood chips and inhaling air flow. The air flow flows out through the air holes at the bottom of the wind catcher 20, which increases the flow rate and pressure of the air flow to a certain extent, enhances the effect of blowing away the wood chips, and at the same time can cool the cut surface of the wood to a certain extent, avoiding excessive temperature due to friction of the rotating cutting line 11.

[0032] A stabilizing groove 2001 of an annular structure is provided on the inner wall of the wind catcher 20, and the end of the centrifugal slider 1004 away from the rotating cutting line 11 is rotatably connected to a stabilizing roller 21. When the clamping shaft 10 rotates to make the centrifugal slider 1004 approach the stabilizing groove 2001, the stabilizing roller 21 will resist the inner wall of the stabilizing groove 2001, which to a certain extent stabilizes the three centrifugal sliders 1004 and prevents the clamping shaft 10 from shaking during rotation.

[0033] A limit block 22 with an arrow-shaped structure is fixedly installed at one end of the No. 2 blade 17 close to the rotating cutting line 11, and a limit column 23 is fixedly installed on the outer wall of the rotating cutting line 11. A plurality of limit slots 2301 are opened on the outer wall of the limit column 23. The limit slots 2301 correspond to the limit blocks 22 one by one. The linkage rod 19 is pushed by the auxiliary push rod 18 to make the limit block 22 inserted into the limit slot 2301, thereby enhancing the stability of the No. 2 blade 17 and avoiding vibration when the No. 2 blade 17 rotates.

[0034] The specific working principle and use method of the present invention are explained in detail below: when in use, first remove the extrusion rod, slightly contract the two telescopic ends of the bidirectional cylinder, so that the rotating cutting line 11 is not in a straight state, at this time, start the No. 1 motor 7 and the No. 2 motor 8 synchronously, so that both run at a lower speed, at this time, the limit clamping tooth 1303 is separated from the locking groove 901 under the action of centrifugal force, and then the clamping column 13 is separated from the drill bit 9; By driving the motor to rotate, the No. 1 motor 7 is placed at the top. When the clamping column 13 is separated from the rotating cutting line 11, the No. 1 motor 7 and the two-way cylinder control can be used to control the drill bit 9 to first punch holes in the cutting part of the wood. The diameter of the hole is slightly larger than the diameter of the clamping column 13, so that the clamping column 13 can pass through the cutting hole and be fixed to the drill bit 9, avoiding cutting from the edge of the wood and causing wood waste; After drilling, the drill bit 9 is inserted into the slot 1301, and then the extrusion rod is inserted into the extrusion hole. At this time, the extrusion rod will hit the inclined surface of the limiting clamping tooth 1303, and the end of the limiting clamping tooth 1303 away from the extrusion rod will be squeezed into the locking groove 901 in the drill bit 9, so that the drill bit 9 and the clamping column 13 are locked. At this time, the drill bit 9 is fixed to the rotating cutting line 11; At this time, the two-way cylinder is started to move its two telescopic ends away from each other, and the rotating rotary cutting line 11 is initially tightened. The driving motor is rotated until the No. 2 motor 8 is at the top, and the No. 1 motor 7 and the No. 2 motor 8 are started synchronously. The rotation speed of the No. 1 motor 7 and the structure and rotation speed of the No. 2 motor 8 are the same, so that the rotation speed of the drill bit 9 and the rotating rotary cutting line 11 are kept synchronous. The rotating rotary cutting line 11 rotates and rubs on the hole wall after drilling, which can produce a cutting effect on the wood, thereby increasing the cutting efficiency of the wood and reducing the roughness of the cut surface of the wood after cutting; At the same time, the second motor 8 drives the support shaft to rotate at a high speed, so that the centrifugal slider 1004 moves the centrifugal slide 1003 away from one end of the plug shaft 12 under the action of centrifugal force. At this time, the end of the telescopic block 14 away from the centrifugal slider 1004 generates a large squeezing force on the bottom of the plug shaft 12, so that the rotating cutting line 11 is in a completely straight state, and the rotating cutting line 11 is rotated and cut along the inner wall of the cutting hole by moving the wood; By swinging the telescopic block 14, the auxiliary push rod 18 pushes the linkage rod 19, and the limit block 22 is further inserted into the limit groove 1302, thereby enhancing the stability of the No. 2 blade 17 and avoiding vibration when the No. 2 blade 17 rotates. The airflow generated by the rotation of the No. 1 blade 16 and the No. 2 blade 17 flows out through the bottom of the wind catcher 20, which plays a role in blowing away the cut wood chips and has a cooling effect to a certain extent. A cutting thread of a certain length is provided on the outer wall of the rotating rotary cutting line 11 to enhance the cutting efficiency. At the same time, a rough structure of a certain length is provided on the outer wall of the rotating rotary cutting line 11, so that the cut surface of the wood can be polished after cutting.

[0035] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
