Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a laser correction platform for saw blade straightness, including a test table 1, a sliding seat 2 fixedly connected to one side surface of the test table 1, a laser spotlight 3 slidably connected to the inner wall surface of the sliding seat 2, a base 4 fixedly connected to one side surface of the test table 1, a sliding groove 5 opened on one side surface of the base 4, an adjustment mechanism 6 provided on one side surface of the base 4, and a saw blade block 7 provided on one side surface of the adjustment mechanism 6. The adjusting mechanism 6 includes a cylinder 601, which is fixedly connected to one side surface of the base 4. A sliding frame 602 is fixedly connected to one side surface of the cylinder 601. A support platform 603 is fixedly connected to one side surface of the sliding frame 602. A guide rod 604 is fixedly connected to one side surface of the support platform 603. A threaded rod 605 is rotatably connected to one side surface of the support platform 603. A handle 606 is fixedly connected to one side surface of the threaded rod 605. A moving part 607 is threadedly connected to the outer wall surface of the threaded rod 605. A connecting plate 608 is fixedly connected to one side surface of the moving part 607. A main shaft 609 is rotatably connected to the upper surface of 602. A track 610 is slidably connected to the outer wall surface of the main shaft 609. A driven shaft 611 is slidably connected to the inner wall surface of the track 610. A straightening column 612 is fixedly connected to the upper surface of the driven shaft 611. A motor 613 is fixedly connected to the lower surface of the main shaft 609. The system is connected via a cylinder 601, a sliding frame 602, a support platform 603, a guide rod 604, a threaded rod 605, a handle 606, a moving part 607, a connecting plate 608, the main shaft 609, the track 610, the driven shaft 611, the straightening column 612, and the motor 613. In setting 13, during use, the threaded rod 605 is rotated by the handle 606. The threaded rod 605 engages with the threaded part 607, causing the moving part 607 to move up and down along the threaded rod 605 under the guidance of the guide rod 604. This adjusts the distance between the moving part 607 and the straightening column 612, ensuring it fits snugly against the saw blade block 7. Simultaneously, the connecting plate 608 moves accordingly, ensuring a more stable connection between the moving part 607 and the saw blade block 7. Next, the cylinder 601 drives the sliding frame 602 to slide within the groove 5 of the base 4, moving the sliding frame 602 and causing the straightening column 612 above the sliding frame 602 to move. The saw blade block 7 is better fitted with the straightening column 612 above the main shaft 609 and the driven shaft 611. The motor 613 is started, which drives the main shaft 609 to rotate. The main shaft 609 drives the driven shaft 611 to rotate through the track 610, thereby making the two straightening columns 612 rotate synchronously. Then, the control system controls the cylinder 601 to adjust the contact pressure and position between the straightening column 612 and the saw blade block 7 according to the saw blade straightness deviation data detected by the laser spotlight 3. The rotating straightening column 612 is used to squeeze and correct the saw blade. It can be compatible with a variety of different specifications and types of saw blades, greatly improving its applicability.

[0017] Furthermore, two slide grooves 5 of the same size are provided and are symmetrically distributed along the base 4. The inner wall size of the slide groove 5 is adapted to the outer wall size of the end of the sliding frame 602 near the cylinder 601. Through the setting of the slide groove 5, the symmetrically distributed double slide grooves 5 provide stable bidirectional guiding support for the sliding frame 602 during use, effectively dispersing the lateral pressure generated during the correction process, avoiding the sliding frame 602 from shifting or tilting, and improving the stability of the mechanism.

[0018] Furthermore, two sets of straightening columns 612 of the same size are provided, and each set has two identical columns. One set of straightening columns 612 is fixedly connected to the surface of the main rotating shaft 609 and the driven rotating shaft 611 away from the motor 613. The other set of straightening columns 612 is symmetrically distributed along the central axis of the sliding frame 602. With the setting of the straightening columns 612, during use, the main rotating shaft 609 and the driven rotating shaft 611 are driven by the motor 613 and rotate synchronously through the track 610, which drives the straightening columns 612 fixed on them to rotate. The two sets of straightening columns 612 symmetrically distributed ensure that the saw blade is subjected to uniform force, effectively avoiding deformation or damage caused by local stress concentration.

[0019] Furthermore, the main shaft 609 and the driven shaft 611 have the same outer wall dimensions and are symmetrically distributed along the side of the support platform 603 away from the base 4. Two moving parts 607 of the same size are provided and are distributed in parallel. Through the arrangement of the main shaft 609 and the driven shaft 611, in use, the main shaft 609 and the driven shaft 611, through the design of the outer wall of the same size and the symmetrical layout, ensure that the tension of the track 610 is uniform during transmission. After the power of the motor 613 is transmitted through the main shaft, it drives the driven shaft 609 to rotate synchronously through the track 610, so that the two sets of straightening columns 612 maintain the same speed, which greatly improves the stability of the mechanism.

[0020] Furthermore, the central axis of the threaded rod 605 is symmetrically distributed with the central axis of the guide rod 604. The guide rod 604 is connected to the moving part 607. Through the arrangement of the threaded rod 605 and the guide rod 604, in use, the threaded rod 605 and the guide rod 604 form a stable parallel double-rail structure through the symmetrical central axis layout. When the handle 606 rotates to drive the threaded rod 605 to rotate, the moving part 607 is constrained by the guide rod 604 and translates along the axial direction of the threaded rod 605 to avoid radial deflection caused by threaded transmission.

[0021] Furthermore, the movable component 607 has a rectangular groove, and the inner wall dimension of the rectangular groove matches the outer wall dimension of the end of the straightening column 612 near the motor 613. The movable component 607 also has a rotating hole, and the inner wall dimension of the rotating hole matches the outer wall dimension of the end of the straightening column 612 near the motor 613. With the movable component 607, the straightening column 612 passes through the rotating hole to achieve axial positioning during use, so that the straightening column 612 can rotate with the rotating shaft and the distance between it and the saw blade block 7 can be adjusted by the translation of the movable component 607, which is highly practical.

[0022] Furthermore, the connecting plate 608 has two of the same size and is arranged in parallel. The test platform 1 has an "L" shaped cross section. With the test platform 1, during use, the test platform 1 with the "L" shaped cross section forms a vertical and horizontal double working surface. The horizontal platform is used to place the saw blade block 7 for straightness detection. The laser spotlight 3 slides and scans along the sliding seat 2 on the horizontal surface, effectively reducing errors.

[0023] Working Principle: When this laser straightness correction platform for saw blades is in operation, firstly, the saw blade block 7 is placed on the test table 1, and the laser spotlight 3 slides along the sliding seat 2 to detect the straightness of the saw blade block 7. The detection data is then fed back to the control system. Next, the saw blade block 7 is placed on the adjustment mechanism 6. By rotating the threaded rod 605 through the handle 606, the threaded rod 605 engages with the moving part 607, causing the moving part 607 to move up and down along the threaded rod 605 under the guidance of the guide rod 604. This adjusts the distance between the moving part 607 and the straightening column 612, making it fit the saw blade block 7. At the same time, the connecting plate 608 moves accordingly to ensure that the moving part 607 and the saw blade block 7 are more stable. Then, the cylinder 601 drives the sliding frame 602 to slide in the sliding groove 5 of the base 4, moving the sliding frame 602 and causing the sliding... The straightening column 612 above the frame 602 better fits the saw blade block 7 with the main rotating shaft 609 and the straightening column 612 above the driven rotating shaft 611. The motor 613 is started, driving the main rotating shaft 609 to rotate. The main rotating shaft 609 drives the driven rotating shaft 611 to rotate through the track 610, thereby making the two straightening columns 612 rotate synchronously. Then, the control system controls the cylinder 601 to adjust the contact pressure and position between the straightening column 612 and the saw blade block 7 according to the saw blade straightness deviation data detected by the laser spotlight 3. The rotating straightening column 612 squeezes and corrects the saw blade. Through repeated detection and correction processes, the straightness of the saw blade is gradually improved until the predetermined standard is reached. The model of the motor 613 is YE2-132S-4. This completes the use process of a laser correction platform for saw blade straightness.
