Description

Technical Field

[0002] In the wood processing industry, four-sided saws are an important cutting equipment and are widely used in the precise cutting of various boards. With the rapid development of the manufacturing industry, the requirements for board processing accuracy and efficiency are increasing. Board positioning is a key link in the four-sided saw processing process, and its accuracy directly affects the quality and production efficiency of the final product.

[0003] Deficiencies of existing technology:

[0004] At present, when positioning the plate, traditional four-sided saw equipment usually relies on the staff to lift the plate onto the four-sided saw fixture and adjust it manually or mechanically to achieve the desired positioning effect. However, this method has many disadvantages. First, because the plate needs to be processed on all four sides, the clamping position of the fixture can often only be set on the upper and lower end surfaces of the plate. This makes it difficult for the staff to judge the positioning of each edge of the plate during positioning, and the lack of intuitive positioning reference increases the difficulty of positioning. Secondly, due to the heavy weight of the plate, especially when processing large plates, the staff needs to frequently move and repeatedly calibrate the plate edge during positioning, which will consume a lot of physical strength and time of the staff. Not only is it inefficient, but it also poses certain safety hazards. Utility Model Content

[0034] See also Figure 1-6As shown, the utility model provides a technical solution for a four-sided saw that is convenient for positioning a plate: a four-sided saw that is convenient for positioning a plate, comprising a base 1 and a cutting portion 2 mounted on the base 1, a double-layer mounting frame 3 is mounted on the upper end surface of the base 1, an auxiliary positioning mechanism 4 for positioning the plate is mounted on one side of the upper end surface of the base 1, a clamping assembly 5 is symmetrically mounted on the double-layer mounting frame 3, and a driving mechanism 6 for driving the plate to move is mounted on one side of the double-layer mounting frame 3. The auxiliary positioning mechanism 4 comprises a fixed support frame 401 and a positioning groove 404. The fixed support frame 401 is mounted on the upper end surface of the base 1, a slide rail 402 is mounted on the upper end surface of the base 1 on one side of the fixed support frame 401, a movable support frame 403 is slidably connected to the slide rail 402, and the cross-sectional shapes of the fixed support frame 401 and the movable support frame 403 are both L-shaped. The positioning groove 404 is provided at the feeding end of the fixed support frame 401 and the moving support frame 403, and an electromagnet block 405 is installed on the inner side of the positioning groove 404, and a positioning block 406 is slidably connected to the positioning groove 404, and a permanent magnet block 407 matching the electromagnet block 405 is installed in the positioning block 406. When the staff needs to load the plate for cutting, first slide the moving support frame 403 according to the width of the plate to be processed, adjust the distance between the moving support frame 403 and the fixed support frame 401, and ensure that the plate can be stably supported. Then set the position of the clamping assembly 5 on the Y axis so that the clamping part of the clamping assembly 5 is located between the fixed support frame 401 and the moving support frame 403. Then control the electromagnet block 405 to be energized, and the electromagnet block 405 generates a repulsive force on the permanent magnet block 407, thereby driving the positioning block 406 to slide upward out of the positioning groove 404. At this time, the staff will place the plate table on the fixed support frame 401 and the movable support frame 403, and the edge of the plate will fit with the fixed support frame 401 and the positioning block 406. At this time, the predetermined position calibration of the plate is completed. The clamping assembly 5 is moved horizontally to the upper and lower sides of the plate to clamp it, and then the electromagnet block 405 is powered off, and the drive mechanism 6 drives the clamping assembly 5 to drive the plate to feed horizontally along the X-axis. Through the auxiliary positioning mechanism 4, the staff only needs to align and fit the edge of the plate with the fixed support frame 401 and the positioning block 406 when loading the material, which reduces the difficulty of positioning. Compared with the traditional need to accurately install and position the plate on the fixture, it does not require repeated calibration, is faster, and has higher efficiency, especially for large plates.

[0035] The driving mechanism 6 includes a mounting cover 601, two mounting shafts 603 and an inner gear 605. The mounting cover 601 is mounted on one side of the double-layer mounting frame 3, and a motor 602 is mounted on one end of the mounting cover 601. The two mounting shafts 603 are respectively movably mounted on the side wall of the double-layer mounting frame 3, located inside the mounting cover 601 and connected to the clamping assembly 5, and a transmission shaft 604 is rotatably connected to the side wall of the double-layer mounting frame 3 above the motor 602. The inner gear 605 is respectively fixedly mounted on the output shaft of the motor 602, the two mounting shafts 603 and one end of the transmission shaft 604 adjacent to the double-layer mounting frame 3, and an outer gear 606 is fixedly mounted on the output shaft of the motor 602 and the end of the transmission shaft 604 away from the double-layer mounting frame 3, and a transmission belt 607 is mounted on the inner gear 605 in the horizontal direction, and the transmission belt 607 is also connected to the outer gear 606. When the clamping assembly 5 needs to move horizontally along the X-axis, the external controller controls the motor 602 to start, and the motor 602 drives the internal gear 605 and the external gear 606 at its output end to rotate, and then the transmission shaft 604 starts to rotate synchronously with the output shaft of the motor 602 under the cooperation of the transmission belt 607 and the external gear 606. The internal gear 605 on the output shaft of the motor 602 and the transmission shaft 604 also rotates synchronously. Under the action of the transmission belt 607, the four internal gears 605 also rotate synchronously, thereby causing the upper and lower mounting shafts 603 to rotate synchronously, thereby driving the clamping assembly 5 at the upper and lower ends of the double-layer mounting frame 3. By controlling the number of revolutions of the motor 602, the position of the plate on the X-axis can be accurately controlled. Through the driving mechanism 6, the effect of synchronously driving the clamping assembly 5 to move horizontally along the X-axis is achieved, meeting the power requirements for accurate feeding of the plate along the X-axis.

[0036] The clamping assembly 5 includes a lead screw 501 and a telescopic rod 503. The lead screw 501 is symmetrically rotated up and down and connected to the inner side of the double-layer mounting frame 3. One end of the lead screw 501 is respectively connected to two mounting shafts 603. A horizontal frame 502 is threadedly connected to the lead screw 501, and both ends of the horizontal frame 502 are respectively slidably connected to the inner wall of the double-layer mounting frame 3. The telescopic rod 503 is respectively slidably connected to the adjacent side of the horizontal frame 502, and the adjacent end of the telescopic rod 503 is installed with a top block 504 for clamping the plate. When the staff needs to load the plate for cutting, first move the telescopic rod 503 along the Y axis and fix it to ensure that the top block 504 is located between the fixed support frame 401 and the movable support frame 403 when it moves to the top. Then start the motor 602 to drive the lead screw 501 to rotate through the two mounting shafts 603, and then drive the telescopic rod 503 to move horizontally along the X axis. Then, the telescopic rod 503 is started to retract and retract, and the plate is clamped and released through the top block 504.

[0037] A plurality of positioning holes 4021 are symmetrically provided on the slide rail 402, and positioning pins 4022 are movably installed in the positioning holes 4021 on both sides of the moving support frame 403. The positioning pins 4022 can be used to position the lower end of the moving support frame 403 to avoid shaking during loading.

[0038] A tensioning roller 6071 is movably mounted on the side wall of the double-layer mounting frame 3 below the transmission belt 607. The tensioning roller 6071 can keep the transmission belt 607 in a tensioned state to ensure the transmission effect.

[0039] A rubber pad is installed on the end surface of the top block 504, and the rubber pad improves the friction force of the end surface of the top block 504, which can better ensure the stability of the plate positioning.

[0040] The working principle of the utility model is as follows:

[0041] When a four-sided saw that is convenient for plate positioning in this embodiment is used, first, according to the width of the plate to be processed, the dynamic support frame 403 is moved to the specified position and the positioning pin 4022 is inserted to fix it, and the distance between the dynamic support frame 403 and the fixed support frame 401 is adjusted to ensure that the plate can be stably supported. Then, the telescopic rod 503 is moved and fixed along the Y axis to ensure that the top block 504 is located between the fixed support frame 401 and the dynamic support frame 403 when it moves to the top. Then, the electromagnet block 405 is controlled to be energized, and the electromagnet block 405 generates a repulsive force on the permanent magnet block 407, thereby driving the positioning block 406 to slide upward out of the positioning groove 404. At this time, the staff will place the plate table on the fixed support frame 401 and the dynamic support frame 403, and the edge of the plate is in contact with the fixed support frame 401 and the positioning block 406. At this time, the predetermined position calibration of the plate is completed. Then, the motor 602 is started to drive the two mounting shafts 603 at the upper and lower ends to rotate, and then the upper and lower lead screws 501 are driven to rotate synchronously, so that the telescopic rod 503 and the top block 504 move to the upper and lower sides of the plate and clamp the plate. Then, the electromagnet block 405 is powered off and the positioning block 406 is reset. At this time, the reverse motor 602 can drive the plate to feed horizontally along the X axis.
