Description

Technical Field

[0001] The present invention relates to the technical field of steel component cutting, and in particular to a cutting mechanism of a fully automatic steel component welding device. Background Art

[0002] In the modern steel component manufacturing industry, welding is a key process for constructing complete steel components. As an important preparatory process before welding, the quality and efficiency of cutting have a decisive impact on the quality and production cycle of the final product. With the development of the demand for steel components in industries such as construction, bridges, and machinery manufacturing towards high precision, large scale, and diversification, fully automatic steel component welding devices have emerged to meet the requirements of efficient and stable production.

[0003] In the prior art, there are various cutting methods for steel components, and laser cutting and cutter cutting are relatively common. With its high-energy-density beam, laser cutting can achieve relatively fine and rapid cutting operations. However, when cutting tubular steel components, the high temperature generated during laser cutting will cause some steel to melt. Under the action of gravity and air flow, these molten substances are extremely likely to adhere to the inner wall of the tubular steel component to form slag. These slags are not only difficult to clean, but also affect the butt joint accuracy of the pipe during subsequent welding, reduce the weld quality, and may even cause defects such as pores and inclusions at the welding site, seriously affecting the cutting effect and the welding quality of the entire steel component.

[0004] During the cutting process of the cutter, due to direct contact and friction with the surface of the steel component, a large cutting force will be generated. This not only easily exacerbates the wear of the cutter, shortens the service life of the tool, increases production costs, but also causes large deformation at the cut surface of the cut steel component. Especially for some thin-walled or high-precision steel components, this deformation may exceed the allowable range, affecting the dimensional accuracy and surface quality of the steel component. Summary of the Invention

[0012] Preferably, the transmission rod includes two rotating sleeves and a sliding rod. The two rotating sleeves respectively penetrate through the two gears fixedly.

[0016] Preferably, the steel plate is in an "L" shape, and one side wall of the steel plate contacts the toothed ring. An anti-slip rubber sleeve is fixedly installed on the circumferential surface of the triangular chuck.

[0017] The present invention has at least the following beneficial effects:

[0018] 1. Adopt an advanced mode of collaborative operation of laser cutting and cutter cutting. In the initial stage, use laser cutting technology, keep the laser cutting position constant, and drive the tubular steel workpiece to rotate at a constant speed. During this process, the laser acts precisely on the surface of the tubular steel workpiece, gradually cutting off a circular part. When the cutting process is approaching the end, at the critical node where it is about to be completed but not fully cut off, quickly switch to cutter cutting. The cutter also performs circular cutting around the tubular steel workpiece. This unique process combination can effectively avoid the problem that slag is easily introduced into the interior of the tubular workpiece during traditional single laser cutting. Because when the laser cutting is nearly completed, the cutter intervenes in a timely manner, preventing excessive slag generated by the continuous action of the laser from entering the pipe wall and affecting subsequent welding operations, significantly reducing the risk of slag contaminating the interior of the workpiece and affecting subsequent processing.

[0019] 2. Adopt a rotational cutting method where the workpiece rotates and the cutting point is fixed. Compared with the traditional one-time cutting method, it can significantly improve the flatness and neatness of the cutting surface. During the rotation process, the cutting point always acts on the workpiece in a stable state, ensuring the consistency and coherence of the cutting path, effectively reducing cutting deviations caused by the movement of the cutting point or the instability of the workpiece, making the cut edge more neat and smooth, greatly improving the cutting quality of the tubular steel workpiece, and providing a better foundation for subsequent processing procedures.

[0020] 3. For plate-shaped workpieces, the processing method is also ingenious. Place the plate-shaped workpiece directly on the support plate evenly provided with rollers. The bottom of the plate-shaped workpiece is in good contact with the rollers, and the top is in contact with the triangular chuck with a high-friction rubber ring on its circumferential surface. When the triangular chuck rotates, relying on the friction of the anti-slip rubber sleeve, it can smoothly drive the plate-shaped workpiece to move, so as to perfectly cooperate with the cutting device for cutting. This design not only makes ingenious use of the driving function of the triangular chuck but also reduces the resistance of the plate-shaped workpiece during movement by means of the rollers, ensuring a smooth and stable cutting process. At the same time, this fixing and driving method expands the application range of the cutting process. Whether it is a tubular workpiece or a plate-shaped workpiece, it can achieve efficient and precise cutting in the mode of collaborative operation of laser cutting and cutter cutting, and laser cutting and cutter cutting can be used arbitrarily.

[0021] 4. The triangular chuck and the auxiliary components cooperate with each other to enable the plate-shaped workpiece to move in one direction, and at the same time, the entire mounting seat can move in another direction perpendicular to it, providing diversity and convenience for the cutting of the plate-shaped workpiece.

[0022] 5. After the tubular workpiece is cut, the two sections of the workpiece can be moved away from each other, causing the entire sliding arm to move downward until the two grinding discs are located between the two sections of the workpiece. Then, the two sections of the workpiece are moved closer again, so that the two cutting surfaces come into contact with the two grinding discs, facilitating the grinding operation. During the grinding process, the grinding discs are driven by the fourth motor, and at the same time, the workpiece rotates on the triangular chuck by means of transmission parts, so that the entire port can be evenly ground, improving the grinding effect.

[0040] Referring to Figures 1-10 , a cutting mechanism of a fully automatic steel component welding device, comprising a base 1, a vertical rod 2 fixedly installed on the surface of the base 1, a sliding arm 4 slidably connected to the surface of the vertical rod 2. The vertical rod 2 is fixedly installed on the surface of the base 1, forming a stable structural connection with the base 1. The sliding of the sliding arm 4 on the surface of the vertical rod 2 is realized by a specific sliding connection structure between the two. The power source is an external first electric telescopic rod 3, which is installed at the top of the vertical rod 2. When the first electric telescopic rod 3 is started to extend or contract, the output end pushes or pulls the sliding arm 4, so that it moves axially up and down along the vertical groove opened on the side wall of the vertical rod 2; a cutting system 12, the cutting system 12 is arranged on the surface of the sliding arm 4, the cutting system 12 includes a turntable 121, a cutting tool 125 and a laser cutting gun 124. The turntable 121 is rotatably connected to the surface of the sliding arm 4. The cutting tool 125 and the laser cutting gun 124 are respectively installed at both ends of the circumferential surface of the turntable 121. The turntable 121 is rotatably connected to the surface of the sliding arm 4. When cutting a tubular steel component, first drive the turntable 121 to switch the laser cutting gun 124 to the working position. The laser cutting gun 124 emits a laser beam with a high energy density, and the tubular steel component can rotate automatically, cutting along the circumference of the tubular steel component, so that the surface material of the steel component is instantly melted or vaporized. When the tubular steel component is about to be completely cut open and only a small part is left connected, drive the turntable 121 again to switch the cutting tool 125 to the working position. The cutting tool 125 performs the final cutting on the part that has been laser cut but not completely separated by rotating at high speed; a mounting seat 5, the mounting seat 5 is arranged on the surface of the base 1, and a mounting component 8 is arranged on the surface of the mounting seat 5. The mounting component 8 includes two mounting plates 83. Both of the two mounting plates 83 are slidably connected to the surface of the mounting seat 5. A second driving mechanism 11 for driving the two mounting plates 83 to move relatively is arranged on the surface of the mounting seat 5. The second driving mechanism 11 can drive the two mounting plates 83 to move relatively, so that the cut steel components can move away from each other by a certain distance, and then the cutting ends of the two steel components can be in contact with the grinding disc 123 for grinding operation. Triangular chucks 81 are arranged on one side of the two mounting plates 83 close to each other. The purpose of fixing the tubular steel component can be achieved through the triangular chucks 81. A transmission member 9 for driving the triangular chuck 81 to rotate is arranged on the surface of the mounting plate 83. The purpose of slowly rotating the fixed tubular steel component is realized by using the transmission member 9, so as to facilitate the uniform cutting of the position to be cut of the steel component at the bottom of the cutting system 12; an auxiliary component 10, the auxiliary component 10 is in two groups and is respectively arranged on the surfaces of the two mounting plates 83 for cooperating with the two triangular chucks 81 to fix and move the plate-shaped steel component. The use of the auxiliary mechanism can enable the device to fix and cut the plate-shaped steel component, improving the functionality.

[0041] Furthermore, the cutting system 12 further includes a fourth motor 122 and a mounting shaft 126. One end of the sliding arm 4 is of an "I" - shaped structure, and an installation groove is formed on its surface. The mounting shaft 126 rotatably penetrates through the installation groove. The turntable 121 is rotatably connected to the surface of the mounting shaft 126. Grinding discs 123 are fixedly installed on both sides of the turntable 121 on the surface of the mounting shaft 126. The fourth motor 122 is fixedly installed on the side wall of the sliding arm 4, and the output shaft port of the fourth motor 122 is fixedly connected to the mounting shaft 126. A first driving mechanism 7 for restricting the rotation of the turntable 121 is arranged on the surface of the sliding arm 4. When it is necessary to perform a grinding operation on the tubular steel member after cutting, first, the two steel members are moved away from each other, the entire sliding arm 4 is lowered, so that the grinding discs 123 are located between the two end steel members. Then, the two steel members are moved closer to contact the two grinding discs 123. The fourth motor 122 is started, and the output shaft of the fourth motor 122 rotates to drive the mounting shaft 126 to rotate in the installation groove. When the mounting shaft 126 rotates, the grinding discs 123 mounted on its surface also rotate accordingly, and the grinding discs 123 can grind the cutting part. The first driving mechanism 7 is used to precisely control the rotation of the turntable 121. When it is necessary to switch the cutting mode, the power source in the first driving mechanism 7 is started, and the power is transmitted to the turntable 121, so that the turntable 121 rotates around the axis of the mounting shaft 126, and the cutting knife 125 and the laser cutting gun 124 are switched to the required working positions.

[0042] Furthermore, the first driving mechanism 7 includes a first motor 73 and a transmission shaft 71. The first motor 73 is fixedly installed on the surface of the sliding arm 4, the transmission shaft 71 is rotatably connected to the surface of the sliding arm 4, the output shaft port of the first motor 73 is fixedly connected to one end of the transmission shaft 71, a worm 72 is fixedly installed on the surface of the transmission shaft 71, a worm gear 74 is fixedly sleeved on the surface of the turntable 121, and the worm 72 meshes with the worm gear 74. The first driving mechanism 7 is used to precisely control the rotation of the turntable 121. When it is necessary to switch the cutting mode, the first motor 73 is started. The first motor 73 is fixed on the surface of the sliding arm 4, and its output shaft drives the transmission shaft 71 fixedly connected thereto to rotate. Since the transmission shaft 71 is rotatably connected to the surface of the sliding arm 4, it can rotate smoothly. The worm 72 fixedly installed on the surface of the transmission shaft 71 rotates accordingly. Also, because the worm 72 meshes with the worm gear 74 fixedly sleeved on the surface of the turntable 121, the worm gear 74 will rotate with the rotation of the worm 72, and then drive the turntable 121 to rotate around the axis, realizing the position switching of the cutting knife 125 and the laser cutting gun 124. At the same time, the transmission mode between the worm gear 74 and the worm 72 has a self - locking effect, so it can be stably maintained at a fixed angle after rotation.

[0043] Furthermore, movable plates 127 are slidably connected to the bottoms of both ends of the "I"-shaped structure of the sliding arm 4. Receiving grooves are formed on the sides of the two movable plates 127 facing each other, and grooves are provided at the bottoms of the receiving grooves. Felt 128 is pasted on the inner walls of the receiving grooves. When the cutting knife 125 cuts the workpiece, debris will bounce out along with the cutting knife 125. The movable plates 127 can be used to block the debris. The relatively soft felt 128 can prevent the debris from rebounding after splashing onto it, so that the debris will fall into the grooves. The movable plates 127 can be inserted into the sliding arm 4. Therefore, even if the sliding arm 4 slides downward, it will not be affected by the movable plates 127.

[0044] Furthermore, the transmission member 9 includes a second motor 93, two gears 94 and a transmission rod. The two gears 94 are fixedly installed on the surface of the transmission rod. Ring gears 82 are rotatably connected to the sides of the two mounting plates 83 facing each other. The triangular chuck 81 is fixedly connected to the ring gear 82. The two gears 94 are respectively engaged with the two ring gears 82. Starting the second motor 93 can make the transmission rod rotate. The transmission rod drives the two gears 94 to rotate. The two gears 94 drive the two ring gears 82 to rotate. The two ring gears 82 drive the two triangular chucks 81 to rotate synchronously, so as to rotate the tubular steel member, which is convenient for keeping the cutting system 12 stationary and automatically rotating the steel member for cutting. This cutting method can perform circumferential cutting on the cutting workpiece, with high cutting neatness and conforming to the way of mutual cooperation of the two cutting methods in this application.

[0045] Furthermore, the transmission rod includes two rotating sleeves 92 and a sliding rod 91. The two rotating sleeves 92 respectively penetrate through the two gears 94 fixedly. The two gears 94 are respectively rotatably connected to the mounting plates 83 through the rotating sleeves 92. One end of the sliding rod 91 is fixedly connected to the rotating sleeve 92 and the other end slidably penetrates through the other rotating sleeve 92. The distance between the two mounting plates 83 needs to be adjusted during use. Therefore, the sliding rod 91 in the transmission rod can slide in the transmission sleeve, which can not only achieve power transmission but also adjust the distance between the two.

[0046] Furthermore, the second driving mechanism 11 includes a third motor 112 and a lead screw 111. Two sliding grooves are formed on the surface of the mounting base 5. Two mounting plates 83 are respectively slidably connected inside the two sliding grooves. The lead screw 111 is rotatably connected inside the sliding groove and the lead screw 111 is provided with two sections of opposite threads with its midpoint as the demarcation line. The two mounting plates 83 are respectively threadedly connected to both ends of the lead screw 111. The third motor 112 is fixedly installed at the end of the mounting base 5. The output shaft port of the third motor 112 is fixedly connected to the lead screw 111. By driving the lead screw 111 to rotate through the third motor 112, the two mounting plates 83 are driven to slide relatively. And the triangular chuck 81 is arranged on the mounting plate 83. Therefore, the distance between the two can be adjusted. Furthermore, when grinding the cut steel member, it is convenient to first move the two away from each other to leave a space for the two grinding discs 123 to be in the middle, and then move closer to make the cutting end contact the grinding disc 123. At the same time, the movement between the two can also adapt to the use of the auxiliary component 10 for plate-shaped steel members of different sizes.

[0047] Furthermore, a vertical groove is formed on the side wall of the vertical rod 2. The sliding arm 4 is slidably connected inside the vertical groove. The top of the vertical rod 2 is fixedly installed with a first electric telescopic rod 3. The output end port of the first electric telescopic rod 3 is fixedly connected to the sliding arm 4. The first electric telescopic rod 3 is used to drive the sliding arm 4 to move in the vertical direction, so that the cutting system 12 is located at a suitable position for normal operation. A horizontal groove is formed on the surface of the base 1. A fixed block is fixedly installed at the bottom of the mounting base 5. The mounting base 5 is slidably connected to the horizontal groove through the fixed block and a second electric telescopic rod 6 is fixedly installed on the inner wall of the horizontal groove. The output end port of the second electric telescopic rod 6 is fixedly connected to the fixed block. The steel member is fixed on the mounting base 5. The mounting base 5 can be adjusted in position by using the second electric telescopic rod 6, which further facilitates the actual operation. The second electric telescopic rod 6 is mainly applied to the cutting of plate-shaped steel members. During use, the plate-shaped steel member is fixed by the cooperation of the mounting component 8 and the auxiliary component 10, so that the cutting line of the plate-shaped steel member is flush with the telescopic direction of the second electric telescopic rod 6 and is located at the bottom of the cutting system 12. Then, the entire mounting base 5 is slid to cooperate with the laser cutting gun 124 in the cutting system 12 to achieve cutting.

[0048] Furthermore, the auxiliary component 10 includes a screw rod 101, a steel plate 102 and a roller 103. A rectangular groove is formed in the surface of the mounting plate 83 near the mounting seat 5. The steel plate 102 is slidably connected to the rectangular groove. The rollers 103 are evenly rotatably connected to the surface of the steel plate 102. The screw rod 101 is rotatably inserted into the interior of the rectangular groove from the top of the mounting plate 83 and is threadedly connected to the steel plate 102. The auxiliary component 10 is mounted on the surface of the mounting plate 83, and its working principle is based on the coordinated operation of the screw rod 101, the steel plate 102 and the roller 103. When it is necessary to fixedly cut the steel plate 102, first place the plate-shaped steel member on the steel plate 102 so that its bottom contacts the roller 103, and adjust the height of the steel plate 102 by rotating the screw rod 101. Since the screw rod 101 is rotatably inserted into the rectangular groove from the top of the mounting plate 83 and is threadedly connected to the steel plate 102, according to the principle of screw drive, when the screw rod 101 rotates, the steel plate 102 will slide up and down in the rectangular groove in the vertical direction until the top of the plate-shaped steel member contacts the circumferential surface of the triangular chuck 81. At this time, the plate-shaped steel member is clamped on the auxiliary components 10 at both ends. By rotating the triangular chuck 81, the plate-shaped steel member can be moved under the action of friction, and then it is cut by the cutting system 12. The roller 103 can make the plate-shaped steel member slide more easily.

[0049] Furthermore, the steel plate 102 is of an "L" shape, and one side wall of the steel plate 102 contacts the toothed ring 82, so that the plate-shaped steel member can be restricted from moving left and right and can only move under the drive of the triangular chuck 81. An anti-slip rubber sleeve 104 is fixedly installed on the circumferential surface of the triangular chuck 81, so that the sliding efficiency of the plate-shaped steel member is higher and cutting is more convenient.

[0050] In summary, an advanced mode of collaborative operation of laser cutting and cutting tool 125 cutting is adopted. In the initial stage, laser cutting technology is used to keep the laser cutting position constant and drive the tubular steel workpiece to rotate at a uniform speed. During this process, the laser acts precisely on the surface of the tubular steel workpiece, gradually cutting off a circular part. When the cutting process is approaching the end, at the critical node where it is about to be completed but not fully cut off, it is quickly switched to cutting with cutting tool 125. The cutting tool 125 also performs circumferential cutting around the tubular steel workpiece. This unique process combination can effectively avoid the problem that slag is easily introduced into the interior of the tubular workpiece during traditional single laser cutting. Because when the laser cutting is nearly completed, the cutting tool 125 intervenes in a timely manner, avoiding excessive slag generated by the continuous action of the laser, and greatly reducing the risk of slag contaminating the interior of the workpiece and affecting subsequent processing. At the same time, the rotary cutting method with the workpiece rotating and the cutting point fixed can significantly improve the flatness and neatness of the cutting surface compared with the traditional direct one-time cutting method of the workpiece. During the rotation process, the cutting point always acts on the workpiece in a stable state, ensuring the consistency and coherence of the cutting path, effectively reducing cutting deviations caused by the movement of the cutting point or the instability of the workpiece, making the cut edge neater and smoother, and greatly improving the cutting quality of the tubular steel workpiece, providing a better basis for subsequent processing operations.

[0051] In the cutting system 12, grinding discs 123 are arranged on both sides of the surface of the mounting shaft 126 located on both sides of the turntable 121 and are driven by the fourth motor 122. After the cutting is completed, by adjusting the position of the mounting plate 83, the two steel components are moved away from each other, the sliding arm 4 moves downward, so that the grinding discs 123 are located between the two steel components, and then the steel components are moved closer to the grinding discs 123. The fourth motor 122 is started to drive the grinding discs 123 to rotate, realizing the grinding of the cutting part, reducing the subsequent manual grinding process, and improving the production efficiency.

[0052] For plate-shaped workpieces, the processing method is also ingenious. The plate-shaped workpiece is directly placed on the support plate evenly provided with rollers 103. The bottom of the plate-shaped workpiece is in good contact with the rollers 103, and the top is in contact with the triangular chuck 81 with a high-friction anti-slip rubber sleeve 104 on the circumferential surface. When the triangular chuck 81 rotates, relying on the friction of the anti-slip rubber sleeve 104, it can smoothly drive the plate-shaped workpiece to move, so as to perfectly cooperate with the cutting device for cutting. This design not only makes ingenious use of the driving function of the triangular chuck 81, but also reduces the resistance when the plate-shaped workpiece moves by means of the rollers 103, ensuring a smooth and stable cutting process. At the same time, this fixing and driving method expands the applicable range of the cutting process. Whether it is a tubular workpiece or a plate-shaped workpiece, it can achieve efficient and precise cutting in the mode of collaborative operation of laser cutting and cutting tool 125 cutting, and laser cutting and cutting tool 125 cutting can be used arbitrarily. At the same time, the plate-shaped workpiece can also be moved by only driving the mounting seat 5 to drive the plate-shaped workpiece to move for cutting, improving the practicability.
