Description

Technical Field

[0001] This utility model belongs to the technical field and relates to a tangential adjustment mechanism, particularly a tangential adjustment mechanism for a metal sawing machine. Background Technology

[0002] A band saw metal cutting machine is a machine tool used for cutting metal materials. It uses a circular saw band tensioned on two saw wheels to drive the cutting motion. The motor in the metal cutting machine drives the worm and worm wheel in the worm gear box via pulleys and V-belts, causing the drive wheel to rotate, which in turn drives the saw blade wound around the rims of the drive and driven wheels to perform the cutting rotation. After the machine tool is placed, the metal needs to be clamped and fixed. However, adjusting the tangential direction after fixing requires disassembly and reassembly, resulting in low work efficiency. Therefore, a tangential adjustment mechanism is needed for metal cutting machines.

[0003] A search revealed a Chinese patent document disclosing a simple cutting machine tool for adjusting the cutting direction [Application No.: CN201620747014.4; Publication No.: CN205733870U]. This simple cutting machine tool uses a cylinder piston rod to push a rack, which in turn drives the teeth to rotate the shaft. The cutting machine rotates with the shaft, thereby adjusting the cutting direction.

[0004] Although the cutting machine tool disclosed in this patent achieves the adjustment of the cutting direction, the cutting machine tool changes the angle by means of a rack and tooth meshing. During the cutting process, a lot of metal debris gets stuck in the teeth, causing wear on the parts and making tangential adjustment inconvenient. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a tangential adjustment mechanism for metal sawing machines. The technical problem this utility model aims to solve is: how to achieve a relative change in the angle between the clamped metal part and the band saw blade, thereby changing the tangential direction, without disassembling the clamped metal part, thus improving work efficiency and reducing the amount of debris stuck in the equipment.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A tangential adjustment mechanism for a metal sawing machine includes a machine body. A clamping and steering mechanism is mounted on the machine body. The clamping and steering mechanism includes a first motor bolted to the machine body. A linear slide rail is fixed to the output end of the first motor. A clamping part is provided within the linear slide rail. A ball bearing is rolled between the linear slide rail and the machine body. The fixed end of the ball bearing is fixed to the bottom left of the linear slide rail. A placement platform is fixed to the front end of the linear slide rail. A connecting rod is fixed to the bottom of the placement platform. An arc-shaped baffle is fixed to the connecting rod. An arc-shaped slide rail is fixed to the machine body. Through slots are provided on both the left and right sides of the arc-shaped slide rail, and the arc-shaped baffle passes through the two through slots.

[0008] The working principle of this utility model is as follows: A first motor drives the linear slide rail to rotate from the bottom. A ball bearing at the other end of the bottom of the linear slide rail rolls on the worktable of the machine tool body, following the linear slide rail's rotation. A connecting rod moves within the arc-shaped slide rail, following the placing platform. An arc-shaped baffle slides within the through-hole of the arc-shaped slide rail, following the connecting rod. The arc-shaped baffle always blocks the top of the arc-shaped slide rail, preventing metal debris generated during sawing from entering the arc-shaped slide rail, keeping it clean and preventing metal debris accumulation that could cause wear. The ball bearing supports the linear slide rail, making it more stable, and reduces friction through its rotation. By directly driving the clamping part to rotate, the angle of the clamped metal part can be adjusted, achieving tangential adjustment without repeatedly removing the metal part from the clamping part, thus improving production efficiency. The first motor, ball bearing, and connecting rod provide three-point support for the linear slide rail and the bottom of the placing platform, ensuring stability.

[0009] The bottom of the connecting rod is rotatably connected to a roller, which rolls within an arc-shaped slide rail.

[0010] With the above structure, when the connecting rod rotates, the roller rotates with the connecting rod in the arc-shaped slide rail, reducing friction and indirectly providing support to the connecting rod from the machine tool body's worktable, thus improving the stability of metal parts clamping and placement.

[0011] The clamping part includes a second motor fixed to the right side of the linear slide rail by bolts, a threaded rod fixed to the output end of the second motor, a slider threadedly connected to the threaded rod, a movable clamping plate fixed to the top of the slider, and a fixed clamping plate fixed to the left side of the linear slide rail.

[0012] Using the above structure, the metal part is placed between the movable clamping plate and the fixed clamping plate, and simultaneously placed on the linear slide rail and the placement platform. The second motor drives the threaded rod to rotate, and the front and rear sides of the slider are fitted into the linear slide rail. The inner wall of the linear slide rail limits the slider, preventing the slider from rotating with the threaded rod. A threaded transmission is formed between the slider and the threaded rod, enabling the slider to move left and right in a linear motion. The movable clamping plate moves left and right in a linear motion with the slider, clamping the metal part between the movable clamping plate and the fixed clamping plate, achieving flexible clamping of metal parts of different specifications.

[0013] A linear baffle is fixed on the left side of the movable clamping plate, and a square groove is opened on the left side of the linear slide rail, with the linear baffle passing through the square groove.

[0014] With the above structure, when the movable clamping plate moves, the linear baffle slides in the square groove of the linear slide rail along with the movable clamping plate, blocking the top of the linear slide rail, reducing the amount of chips entering the linear slide rail during the sawing process, preventing chips from contacting the threaded rod and causing wear, and extending the service life of the equipment.

[0015] Both the rear end of the linear slide rail and the front end of the placement platform are fixed with connecting corner pieces. A base is fixed on the opposite side of the two connecting corner pieces. A viewing cover is hinged on the base. Square holes are opened at both the front and rear ends of the viewing cover. The material of the viewing cover is quartz glass.

[0016] Using the above structure, after clamping the metal part, a viewing cover is placed on top. The square holes in the viewing cover are used to prevent the metal part from preventing the viewing cover from closing. The metal part passes through two square holes. When the linear slide rail and the placement platform rotate, the viewing cover rotates with the linear slide rail through the connecting corner pieces and the base, so that tangential adjustment can still be made after the viewing cover is closed. The viewing cover is used to reduce the contact between metal chips and air during the sawing process, reduce the possibility of operators coming into contact with chips, improve the environmental quality of the production workshop, and ensure the production safety of operators.

[0017] A circular hole is provided on the right side of the visible cover, and a waste suction machine is connected to the flange on the right side of the circular hole.

[0018] With the above structure, a waste suction machine is connected to the inside of the viewing enclosure. During the sawing process, the waste suction machine operates to suck up metal scraps. The viewing enclosure reduces the range of scrap splashing, improves the suction efficiency of the waste suction machine, and accelerates the air circulation inside the viewing enclosure, which helps to cool down the machine and prevent frictional heat generation and overheating of the equipment during sawing.

[0019] The waste suction machine is connected to the visible cover via a corrugated pipe.

[0020] By adopting the above structure and utilizing the deformable characteristics of the bellows, the bellows can maintain the connection between the waste suction machine and the visible cover during the opening and closing process, reducing the number of times the flange is disassembled and improving work efficiency.

[0021] Compared with existing technologies, the tangential adjustment mechanism for metal sawing machines has the following advantages:

[0022] 1. By setting up an arc-shaped baffle to always cover the top of the arc-shaped slide rail, metal shavings generated during sawing are prevented from entering the arc-shaped slide rail, keeping the inside of the arc-shaped slide rail clean and preventing metal shavings from accumulating inside the equipment and causing wear. The ball bearings support the linear slide rail, making it more stable, and the rotation of the ball bearings reduces friction. By directly driving the rotation of the clamping part, the angle of the clamped metal part can be adjusted, thereby achieving tangential adjustment. There is no need to repeatedly remove the metal part from the clamping part, improving production efficiency. The first motor, ball bearings, and connecting rod provide three-point support for the linear slide rail and the bottom of the placement platform, which has stability.

[0023] 2. By clamping metal parts between the movable clamping plate and the fixed clamping plate, it is possible to clamp metal parts of different specifications. It is flexible. When the movable clamping plate moves, the linear baffle slides in the square groove of the linear slide rail with the movable clamping plate, which blocks the top of the linear slide rail, reduces the amount of chips entering the linear slide rail during the sawing process, avoids chip contact with the threaded rod and causes wear, and extends the service life of the equipment.

[0024] 3. The viewing cover rotates along the linear slide rail via connecting corner pieces and the base, allowing for tangential adjustment even when the cover is closed. The viewing cover reduces contact between metal scraps and air during sawing, minimizing operator contact with scraps and improving the environmental quality of the production workshop while ensuring operator safety. A scrap suction machine is connected inside the viewing cover and operates during sawing to suck up metal scraps. The viewing cover also reduces the scrap splash range, improving the suction machine's efficiency. Furthermore, the scrap suction machine accelerates airflow within the viewing cover, cooling the equipment and preventing frictional heat generation and overheating during sawing.

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figures 1-6 As shown, the tangential adjustment mechanism for a metal sawing machine includes a machine body 1. A clamping and turning mechanism 2 is provided on the machine body 1. The clamping and turning mechanism 2 includes a first motor 201 fixed inside the machine body 1 by bolts. A linear slide rail 202 is fixed to the output end of the first motor 201. A clamping part is provided inside the linear slide rail 202. A ball bearing 203 is rolled between the linear slide rail 202 and the machine body 1. The fixed end of the ball bearing 203 is fixed to the bottom left of the linear slide rail 202. A placement platform 205 is fixed to the front end of the linear slide rail 202. A connecting rod 211 is fixed to the bottom of the placement platform 205. An arc-shaped baffle 212 is fixed on the connecting rod 211. An arc-shaped slide rail 213 is fixed on the machine body 1. Through slots are opened on both the left and right sides of the arc-shaped slide rail 213. The arc-shaped baffle 212 passes through the two through slots.

[0034] In this embodiment, both the first motor 201 and the machine tool body 1 are existing technologies. The first motor 201 drives the linear slide rail 202 to rotate from the bottom. The ball bearing 203 at the other end of the bottom of the linear slide rail 202 rolls on the worktable of the machine tool body 1 along with the linear slide rail 202. The placement platform 205 rotates with the linear slide rail 202. The connecting rod 211 moves within the arc-shaped slide rail 213 along with the placement platform 205. The arc-shaped baffle 212 slides within the through hole of the arc-shaped slide rail 213 along with the connecting rod 211. The arc-shaped baffle 212 always blocks the top of the arc-shaped slide rail 213 to prevent sawing activities from occurring. Metal scraps enter the arc-shaped slide rail 213, keeping the inside of the arc-shaped slide rail 213 clean and preventing metal scraps from accumulating inside the equipment and causing wear. The ball bearings 203 support the linear slide rail 202, making it more stable. At the same time, the rotation of the ball bearings 203 reduces friction. By directly driving the clamping part to rotate, the angle of the clamped metal part can be adjusted, thereby achieving tangential adjustment. There is no need to repeatedly remove the metal part from the clamping part, improving production efficiency. The first motor 201, ball bearings 203, and connecting rod 211 provide three-point support for the linear slide rail 202 and the bottom of the placement platform 205, which has stability.

[0035] A roller 214 is rotatably connected to the bottom of the connecting rod 211. The roller 214 rolls within the arc-shaped slide rail 213. In this embodiment, when the connecting rod 211 rotates, the roller 214 rotates with the connecting rod 211 within the arc-shaped slide rail 213, reducing friction and indirectly providing support to the connecting rod 211 from the worktable surface of the machine tool body 1, thereby improving the stability of the metal parts clamping and placement.

[0036] The clamping part includes a second motor 204 fixed to the right side of the linear slide rail 202 by bolts. A threaded rod 206 is fixed to the output end of the second motor 204, and a slider 207 is threadedly connected to the threaded rod 206. A movable clamping plate 208 is fixed to the top of the slider 207, and a fixed clamping plate 209 is fixed to the left side of the linear slide rail 202. In this embodiment, the second motor 204 is existing technology. The metal part is placed between the movable clamping plate 208 and the fixed clamping plate 209, and simultaneously placed on the linear slide rail 202 and the placement platform 205. Motor 204 drives threaded rod 206 to rotate. The front and rear sides of slider 207 are fitted into linear slide rail 202. The inner wall of linear slide rail 202 limits slider 207 to prevent slider 207 from rotating with threaded rod 206. Threaded transmission is formed between slider 207 and threaded rod 206, enabling slider 207 to move left and right linearly. Movable clamping plate 208 moves left and right linearly with slider 207, clamping metal parts between movable clamping plate 208 and fixed clamping plate 209, achieving flexible clamping of metal parts of different specifications.

[0037] A linear baffle 210 is fixed to the left side of the movable clamping plate 208. A square groove is provided on the left side of the linear slide rail 202, and the linear baffle 210 passes through the square groove. In this embodiment, when the movable clamping plate 208 moves, the linear baffle 210 slides with the movable clamping plate 208 in the square groove of the linear slide rail 202, blocking the top of the linear slide rail 202, reducing the entry of debris into the linear slide rail 202 during the sawing process, preventing debris from contacting the threaded rod 206 and causing wear, and extending the service life of the equipment.

[0038] Both the rear end of the linear guide rail 202 and the front end of the placement platform 205 are fixed with connecting corner pieces 301. A base 302 is fixed to the opposite side of the two connecting corner pieces 301. A viewing cover 303 is hinged to the base 302. Square holes are provided at both the front and rear ends of the viewing cover 303. The viewing cover 303 is made of quartz glass. In this embodiment, after clamping the metal part, the viewing cover 303 is covered. The square holes in the viewing cover 303 are used to prevent the metal part from damaging the viewing cover 303. 3. The cover cannot be closed. The metal parts are inserted into the two square holes. When the linear slide rail 202 and the placement platform 205 rotate, the visible cover 303 rotates with the linear slide rail 202 through the connecting corner piece 301 and the base 302. This allows the visible cover 303 to be closed while still being tangentially adjustable. The visible cover 303 is used to reduce the contact between metal chips and air during the sawing process, reduce the possibility of operators coming into contact with chips, improve the environmental quality of the production workshop, and ensure the production safety of operators.

[0039] A circular hole is provided on the right side of the viewing cover 303. A waste suction machine 4 is connected to the flange on the right side of the circular hole. In this embodiment, the waste suction machine 4 is the prior art. The waste suction machine 4 is connected to the inside of the viewing cover 303. During the sawing process, the waste suction machine 4 is operated to suck up metal scraps. The viewing cover 303 reduces the range of scrap splashing, improves the suction efficiency of the waste suction machine 4, and accelerates the air circulation inside the viewing cover 303, which plays a role in cooling down and preventing frictional heat generation and overheating of the equipment during the sawing process.

[0040] The waste suction machine 4 is connected to the visible cover 303 by a corrugated pipe. In this embodiment, by utilizing the deformable characteristics of the corrugated pipe, the corrugated pipe can maintain the connection between the waste suction machine 4 and the visible cover 303 during the opening and closing process, thereby reducing the number of times the flange is disassembled and improving work efficiency.

[0041] The working principle of this utility model is as follows: A metal part is placed between a movable clamping plate 208 and a fixed clamping plate 209, and simultaneously placed on a linear slide rail 202 and a placement platform 205. A second motor 204 drives a threaded rod 206 to rotate. The front and rear sides of a slider 207 are fitted into the linear slide rail 202. The inner wall of the linear slide rail 202 limits the slider 207, preventing it from rotating with the threaded rod 206. A threaded transmission is formed between the slider 207 and the threaded rod 206, allowing the slider 207 to move left and right linearly. The movable clamping plate 208 moves left and right linearly with the slider 207, clamping the metal part between the movable clamping plate 208 and the fixed clamping plate 209. When the movable clamping plate 208 moves, a linear baffle 210 slides within the square groove of the linear slide rail 202, blocking the top of the linear slide rail 202. After clamping the metal part, a viewing cover 303 is placed over it, making the metal part visible. The square holes in the cover 303 are designed to prevent metal parts from preventing the cover 303 from closing. The metal parts pass through the two square holes. When the linear slide rail 202 and the placement platform 205 rotate, the cover 303 rotates with the linear slide rail 202 via the connecting corner piece 301 and the base 302, allowing tangential adjustment to be made even after the cover 303 is closed. The first motor 201 drives the linear slide rail 202 to rotate from the bottom of the linear slide rail 202. The ball bearing 203 at the other end rolls on the worktable of the machine tool body 1 following the linear slide rail 202. The placement platform 205 rotates with the linear slide rail 202. The connecting rod 211 moves within the arc-shaped slide rail 213 following the placement platform 205. The arc-shaped baffle 212 slides within the through hole of the arc-shaped slide rail 213 following the connecting rod 211. The arc-shaped baffle 212 always blocks the top of the arc-shaped slide rail 213. During the sawing process, the waste suction machine 4 is operated to suck up metal chips.

[0042] In summary, by setting up a clamping and steering mechanism, the relative angle between the clamped metal part and the band saw blade can be changed, altering the tangential direction, without needing to disassemble the clamped metal part, thus improving work efficiency and reducing the amount of debris stuck in the equipment.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
