Description

Technical Field

[0001] This utility model relates to the field of saw blade welding technology, and in particular to an alloy tooth saw blade welding machine. Background Technology

[0002] In the process of band saw blade welding, band saw blade welding machines are widely used to weld various metal band saw blades. A band saw blade consists of a tough, sharp-toothed blade tensioned in a frame and is used to cut metal and other shaped materials. As the band saw blade is used for a long time, the cutting edge of the band saw blade gradually becomes dull, or the saw teeth are lost due to external forces, which may lead to the band saw breaking. Therefore, it is necessary to weld the band saw blade.

[0003] Chinese Patent No. CN220921126U discloses an alloy toothed saw blade welding machine, including a worktable. A fixing plate is fixedly connected to the center of the front end of the top of the worktable. Second cylinders are fixedly connected to the center of the left and right sides of the rear end of the fixing plate. Extrusion plates are fixedly connected to the output ends of the two second cylinders. A fixing box is fixedly connected to the center of the rear end of the top of the worktable. A placement cavity is provided through the bottom upper part of the front end of the fixing box. Support legs are fixedly connected to the four corners of the top of the worktable. In this invention, the first cylinder retracts, and the second cylinder extends to clamp the saw blade, avoiding the reduction in yield due to saw blade misalignment caused by ineffective fixation. The third cylinder extends and pushes the plate, pushing the fixing column to press against the saw blade, allowing the saw blade to advance. The next saw tooth can be welded without manual operation.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing alloy tooth saw blade welding machine cannot clamp saw blades of different widths during use, and cannot completely limit the saw blade during the clamping process, which may cause the saw blade to slip during the welding process, thus affecting the welding effect. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it is impossible to fully limit the movement of saw blades of different widths, and to propose an alloy tooth saw blade welding machine.

[0006] The technical solution of this utility model: an alloy toothed saw blade welding machine, including a mounting platform and an operating table disposed on top of the mounting platform; further comprising:

[0007] The clamping and limiting mechanism is located on the top of the mounting platform. There are two clamping mechanisms symmetrically arranged about the mounting platform. They are used to clamp saw blades of different widths and limit the front and rear positions of the saw blades during the clamping process.

[0008] The first clamping platform is mounted on the clamping and limiting mechanism. The first clamping platform has a sliding groove, on which a limiting plate is slidably mounted. The bottom of the first clamping platform has a second clamping platform, on which a slot is mounted. The limiting plate is divided into two parts: the left limiting plate is a vertical plate, and the right limiting plate is a serrated plate, which is used to cooperate with the two sides of the saw blade for limiting. The slot and the limiting plate correspond one to one. The first clamping platform is pressed down by the clamping and limiting mechanism to clamp the saw blade. At the same time, the limiting plate and the slot are connected.

[0009] Preferably, the clamping and limiting mechanism includes a cylinder, a fixed frame, and a push rod;

[0010] The mounting bracket is located on the top of the mounting platform, the cylinder is located on the top of the mounting bracket, the push rod is located at the output end of the cylinder, the bottom of the push rod is connected to the top of the clamping platform, the side of the limiting plate is provided with a threaded rod, the end of the threaded rod away from the limiting plate is provided with a power rod, and the outer side of the threaded rod is threaded with a fixing block.

[0011] Preferably, a connecting plate is slidably provided on the side of the fixed frame, a welding machine is provided on the top of the connecting plate, and a welding head is provided at the output end of the welding machine.

[0012] Preferably, it also includes an intermittent pushing mechanism, which includes a positioning component and a pushing component;

[0013] The positioning component is located on the side of the clamping table 2 and is used to push the pushing component so that it is located directly below the saw teeth side of the saw blade;

[0014] The push component is set on the positioning component and is used to intermittently and automatically push the saw blade forward.

[0015] Preferably, the positioning assembly includes slide rail one, slide rail two, vertical plate and insert rod;

[0016] Slide rail one is located on the side of clamping platform two, slide rail two is slidably located on slide rail one, vertical plate is located on the top of slide rail two, insertion rod is slidably located on vertical plate, spring is provided on the outside of insertion rod, pull rod is provided at the end of insertion rod, and insertion hole is provided on the side of clamping platform two.

[0017] Preferably, the pushing component includes a sliding table, a first rotating rod, a second rotating rod, and a rotating shaft;

[0018] The sliding table is slidably mounted on the slide rail 2. Rotating rod 1 is rotatably mounted at the bottom of the sliding table. Rotating rod 2 is rotatably mounted at the end of rotating rod 1 away from the sliding table. Rotating shaft is mounted at the end of rotating rod 2 away from rotating rod 1. A motor is mounted at the end of rotating shaft away from rotating rod 2. A sliding frame is mounted on the outside of the motor. The outside of the sliding frame is slidably connected to the mounting platform. A connecting block is mounted on the top of the sliding table. A pushing component is rotatably mounted on the inside of the connecting block.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] 1. By setting up a clamping and limiting mechanism, the position of the limiting plate can be adjusted to accommodate saw blades of different widths. The cylinder drives clamping platform one and clamping platform two to clamp the saw blade. During the clamping process, the limiting plate limits both sides of the saw blade. This can precisely control the position of the saw blade during the welding process, ensure the accuracy of the welding point, avoid welding defects caused by saw blade deviation, reduce errors caused by human operation, and improve the consistency and stability of welding. At the same time, it can clamp saw blades of different widths, making the welding machine more versatile and able to meet different production needs.

[0021] 2. With the intermittent pushing mechanism, the motor drives the sliding table to move back and forth. When the sliding table moves to the left, it pushes the saw blade forward, and when it moves to the right, the position of the saw blade remains unchanged. This enables continuous and stable welding operations, reduces manual intervention, improves production efficiency, and allows for precise control of the pushing distance and position of the saw blade, ensuring that the position of each weld is consistent and avoiding welding deviations caused by human operation. At the same time, when used in conjunction with the cylinder, the cylinder pushes the saw blade again when it releases the saw blade, reducing rigid damage to the saw blade.

[0028] Example 1

[0029] like Figures 1-3 As shown, the alloy toothed saw blade welding machine proposed in this utility model includes a mounting platform 1, an operating platform 2 disposed on the top of the mounting platform 1, a clamping and limiting mechanism, and a clamping table 304.

[0030] The clamping and limiting mechanism is located on the top of the mounting platform 1. There are two clamping mechanisms symmetrically arranged about the mounting platform 1. They are used to clamp saw blades of different widths and limit the front and rear positions of the saw blades during the clamping process.

[0031] A clamping platform 304 is mounted on a clamping and limiting mechanism. A sliding groove is provided on the clamping platform 304, and a limiting plate 308 is slidably mounted on the sliding groove. A second clamping platform 309 is provided at the bottom of the clamping platform 304, and a slot 310 is provided on the second clamping platform 309. The limiting plate 308 is divided into two parts: the left limiting plate 308 is a vertical plate, and the right limiting plate 308 is a serrated plate, which is used to cooperate with the two sides of the saw blade for limiting. The slot 310 and the limiting plate 308 correspond one-to-one. The clamping platform 304 is pressed down by the clamping and limiting mechanism to clamp the saw blade. At the same time, the limiting plate 308 and the slot 310 cooperate and connect.

[0032] The clamping and limiting mechanism includes a cylinder 301, a fixed frame 302, and a push rod 303. The fixed frame 302 is located on the top of the mounting platform 1, the cylinder 301 is located on the top of the fixed frame 302, the push rod 303 is located at the output end of the cylinder 301, the bottom of the push rod 303 is connected to the top of the clamping platform 1 304, a threaded rod 306 is provided on the side of the limiting plate 308, and a power rod 307 is provided at the end of the threaded rod 306 away from the limiting plate 308. A fixing block 305 is connected to the side thread. The outer side of the fixing block 305 is connected to the bottom of the clamping table 304. Rotating the power rod 307 causes the limiting plate 308 to slide on the clamping table 304 via the threaded rod 306. After adjusting to the size suitable for the saw blade, the rotation of the power rod 307 is stopped. Then, the cylinder 301 is started. The cylinder 301 drives the push rod 303 to move. The push rod 303 drives the clamping table 304 to press down, thereby completing the intermittent clamping of the saw blade.

[0033] A connecting plate 501 is slidably mounted on the side of the fixed frame 302. A welding machine 502 is mounted on the top of the connecting plate 501. A welding head 503 is mounted on the output end of the welding machine 502. The connecting plate 501 is moved so that the welding machine 502 is positioned directly above the saw blade. The welding machine 502 is started, and the welding machine 502 performs welding processing on the saw blade through the welding head 503.

[0034] Example 2

[0035] like Figures 4-5 As shown, this utility model proposes an alloy toothed saw blade welding machine. Compared with Embodiment 1, this embodiment details the structure of the intermittent pushing mechanism.

[0036] The intermittent pushing mechanism includes a positioning component and a pushing component. The positioning component is located on the side of the clamping table 309 and is used to push the pushing component to position it directly below the saw teeth side of the saw blade. The pushing component is located on the positioning component and is used to intermittently and automatically push the saw blade forward. The positioning component includes a slide rail 401, a slide rail 402, a vertical plate 409, and a rod 410. The slide rail 401 is located on the side of the clamping table 309, the slide rail 402 is slidably mounted on the slide rail 401, the vertical plate 409 is located on the top of the slide rail 402, the rod 410 is slidably mounted on the vertical plate 409, a spring 412 is provided on the outer side of the rod 410, a pull rod 411 is provided at the end of the rod 410, and an insertion hole 413 is provided on the side of the clamping table 309. Located above slide rail 401, and with multiple insertion holes 413 evenly arranged on clamping platform 309, insertion holes 413 and insertion rods 410 can be connected together. Pulling the pull rod 411 causes the insertion rod 410 to disengage from the insertion hole 413. At this time, slide rail 402 can be controlled to slide on slide rail 401. After moving to directly below the saw teeth side of the saw blade, the pull rod 411 is released. Under the action of spring 412, the pull rod 411 rebounds and locks into the insertion hole 413 at that position, thereby fixing the position of slide rail 402.

[0037] Example 3

[0038] like Figures 4-5 As shown, this utility model proposes an alloy toothed saw blade welding machine. Compared with Embodiment 1 and Embodiment 2, this embodiment details the structure of the pushing component.

[0039] The pushing component includes a sliding table 403, a first rotating rod 404, a second rotating rod 405, and a rotating shaft 406. The sliding table 403 is slidably mounted on the second sliding rail 402. The first rotating rod 404 is rotatably mounted at the bottom of the sliding table 403. The second rotating rod 405 is rotatably mounted at the end of the first rotating rod 404 away from the sliding table 403. The rotating shaft 406 is located at the end of the second rotating rod 405 away from the first rotating rod 404. A motor 407 is mounted at the end of the rotating shaft 406 away from the second rotating rod 405. A sliding frame 408 is mounted on the outside of the motor 407. The outside of the sliding frame 408 is slidably connected to the mounting platform 1. A connecting block 414 is mounted on the top of the sliding table 403. A pushing component 415 is rotatably mounted on the inside of the connecting block 414. When the motor 407 is started, the motor 407 drives the second rotating rod 405 to rotate via the rotating shaft 406. 405 drives the first rotating rod 404 to rotate. The length of the first rotating rod 404 is greater than that of the second rotating rod 405. Therefore, the first rotating rod 404 drives the sliding table 403 to slide back and forth on the second sliding rail 402. During the sliding process, since the pusher 415 is set in an angle shape and one end abuts against the top of the sliding table 403, the position of the pusher 415 remains unchanged and can push the saw blade when the sliding table 403 moves to the left. When it moves to the right, there is no object abutting the right side of the pusher 415, so the pusher 415 can rotate without affecting the position of the saw blade. The cylinder 301 and the motor 407 work together. During the return stroke of the cylinder 301, the motor 407 drives the pusher 415 to push the saw blade to the left. During the downward output stroke of the cylinder 301, the motor 407 drives the sliding table 403 to return.

[0040] In summary, when using this utility model, the saw blade is placed on the two clamping platforms 309. The power rod 307 is rotated, and the power rod 307 drives the limiting plate 308 to slide on the clamping platform 304 via the threaded rod 306. After adjusting to the size suitable for the saw blade, the rotation of the power rod 307 is stopped. Then, the pull rod 411 is pulled to drive the insertion rod 410 to disengage from the insertion hole 413. The slide rail 402 is moved to directly below the saw teeth side of the saw blade, and then the pull rod 411 is released. Under the action of the spring 412, the pull rod 411 rebounds and locks into the insertion hole 413 at that position, thereby fixing the position of the slide rail 402. Then, the operation of the cylinder 301 and the motor 407 is set through the operating table 2, and the welding machine 502, cylinder 301 and motor 407 are started. The cylinder 301 drives the push rod 303 to move, and the push rod 303 drives the clamping platform 304 to press down, thereby completing the intermittent clamping of the saw blade. At this time, the limiting plates 308 on both sides and the two sides of the saw blade are connected to limit the position. When clamping, the welding machine 502 welds the saw blade through the welding head 503. After one saw tooth is welded, the motor 407 drives the rotating rod 405 to rotate through the rotating shaft 406. The rotating rod 405 drives the rotating rod 404 to rotate. The length of the rotating rod 404 is greater than that of the rotating rod 405. Therefore, the rotating rod 404 drives the sliding table 403 to slide back and forth on the sliding rail 402. When the sliding table 403 moves to the left, the position of the pusher 415 remains unchanged and pushes the saw blade. When it moves to the right, the position of the saw blade remains unchanged. The cylinder 301 and the motor 407 work together. When the cylinder 301 returns, the motor 407 drives the pusher 415 to push the saw blade to the left. When the cylinder 301 outputs downward, the motor 407 drives the sliding table 403 to return.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
