Description

Technical Field

[0001] This utility model relates to a cutting device, specifically a flexible cutting device for saw blade substrate. Background Technology

[0002] During the manufacturing process of the saw blade substrate, the plate needs to be laser-cut to create a saw blade substrate with serrations.

[0003] Traditional laser cutting platforms have many support bars with several sharp ends at the top. The plate material of the saw blade base is then placed on the support bars, forming many point contacts to ensure that the plate material is level.

[0004] In existing technologies, when support bars on laser cutting platforms are used for extended periods, the laser cuts the sheet metal from top to bottom, causing some support points on the support bars to be cut by the laser. This makes the support bars prone to wear and laser burn-out, resulting in instability in supporting the saw blade sheet metal. Timely replacement is necessary to ensure the stability of the support for the saw blade sheet metal. However, some support points on the support bars remain intact because they are not burned by the laser. Furthermore, the horizontal position of the sheet metal is not always consistent, and the damaged position of the support bar will also change each time. Replacing the entire support bar directly would be wasteful, have high maintenance costs, and be laborious. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible cutting device for saw blade substrate, which solves the problems of laborious replacement and high maintenance cost in the existing technology.

[0006] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: a flexible cutting device for saw blade substrate, including a worktable, a three-axis robotic arm on the top surface of the worktable, a support platform on the adjacent side of the three-axis robotic arm, a laser cutting head at the end of the three-axis robotic arm corresponding to the support platform, a fixed cavity on the top of the support platform, a plurality of staggered support blocks with their tips pointing upwards in the fixed cavity, a fixed seat at the bottom of the fixed cavity, a fixed groove on the fixed seat that cooperates with the support blocks and limits the support blocks on both sides, two symmetrically arranged side support rods that can limit the support blocks laterally and a locking block that can limit the support blocks longitudinally and is located on the top of the side support rods and can reciprocate toward the support blocks.

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] like Figure 1-3As shown, a flexible saw blade substrate cutting device includes a worktable 1, a three-axis robotic arm 2 on the top surface of the worktable 1, a support platform 3 adjacent to the three-axis robotic arm 2, and a laser cutting head 21 at the end of the three-axis robotic arm 2 corresponding to the support platform 3. This three-axis robotic arm is existing technology and can drive the laser cutting head to move along the X, Y, and Z axes. The laser cutting head is also existing technology and will not be described in detail here. This allows for flexible and efficient cutting of the saw blade plate placed on the support platform, forming multiple saw blade substrates. The top of the support platform 3 has a fixed cavity 31, within which are several staggered support blocks 32 with their tips pointing upwards. The support blocks are evenly and staggered within the fixed cavity, with their tips pointing upwards to provide point support for the plate. The bottom of the fixed cavity 31 has a fixed seat 33, which is fixed to the fixed cavity. The fixed seat 33 has a fixing groove 331 that cooperates with the support blocks 32 and limits their movement on both sides. The fixing groove is formed in the fixed seat. The upper part has a horizontally penetrating and upward-opening structure. The fixing groove 331 contains two symmetrically arranged side support rods 34 that laterally limit the support block 32, and a locking block 35 located on top of the side support rods 34 that longitudinally limits the support block 32 and can reciprocate toward the support block 32. The two side support rods are symmetrically arranged on both sides of the fixing groove, and the two locking blocks are located on top of the two side support rods respectively. When the support block is fixed in the fixing groove, the two sides of the support block in the width direction abut against the two sides of the fixing groove, and the two sides of the support block in the length direction abut against the side walls of the side support rods, achieving lateral limitation. The locking blocks move toward the support block from the top of the side support rods and abut against the top of the support block, longitudinally limiting the top of the support block, thereby fixing the support block and ensuring the stability of the support block in supporting the plate, ensuring stability and reliability when cutting the plate. Simultaneously, by moving the locking blocks, damaged support blocks can be removed individually and replaced with intact ones, making replacement and maintenance simpler and more convenient, effectively reducing maintenance costs.

[0020] like Figure 2-4As shown, the support block 32 includes a support portion 321 with a pointed tip and a fixing portion 322 connected to the fixing seat 33. The support portion is located on the upper side to support the saw blade plate, and the fixing portion is located on the lower side, placed in the fixing groove. When the support block is fixed in the fixing groove, the fixing portion 322 can abut against the side walls of the fixing groove 331 on both sides, and the other two sides of the fixing portion 322 can abut against the side walls of the two symmetrical side support rods 34. The top of the fixing portion 322 can abut against the locking block 35, forming a lateral limit on the support block and maintaining the stability of the support block. The fixing groove 331 is open at both ends. The top of the side support rod 34 is provided with a guide block 341, and the bottom of the locking block 35 is provided with a guide groove 351 that cooperates with the guide block 341 and is arranged along the moving direction of the locking block 35. The setting of the guide block and the guide groove is to facilitate the positioning of the locking block, maintain the stability of the locking block position, and guide the movement of the locking block. To maintain stability during the movement of the locking block, the locking block can be moved to longitudinally limit the support block or separate from the support block, thereby locking and unlocking the support block. The bottom outer side of the locking block 35 is provided with a groove 352. The groove is designed to facilitate the operator to pull the locking block, making the operation easier. The bottom of the locking block 35 is provided with a fixing plate 353 corresponding to the outer side of the side support rod 34. The side wall of the side support rod 34 is provided with a first receiving groove 342 corresponding to the fixing plate 353. The first receiving groove 342 is provided with a first telescopic spring 343 connected to the fixing plate 353. The fixing plate is connected to one end of the first telescopic spring, and the other end of the first telescopic spring is connected to the first receiving groove. This allows the locking block to automatically move upward towards the fixed part through the action of the first telescopic spring, maintaining the locked state of the support block. At the same time, pulling the locking block in the opposite direction can release the locking state of the locking block on the support block.

[0021] like Figure 3As shown, the bottom end of the side support rod 34 is rotatably connected to the side wall of the fixing groove 331 via a rotating shaft 344. A bottom support rod 36, perpendicular to the side support rod 34 and capable of abutting against the bottom of the fixing part 322, is provided on the side wall of the rotating shaft 344. The contact surfaces of the side support rod and the bottom support rod with the fixing part are perpendicularly arranged to ensure a tight fit with the side wall and bottom of the fixing part, guaranteeing reliable and stable fixing of the support block and preventing the support block from shifting or loosening, thus ensuring stable support for the saw blade plate. Both the side support rod and the bottom support rod rotate around the rotating shaft as the rotation center. A second receiving groove 332 is provided at the bottom of the fixing groove 331 corresponding to the area below the bottom support rod 36. A second telescopic spring 333 is provided in the second receiving groove 332. A limiting block 334, located on the rotation path outside the side support rod 34, is provided in the fixing groove 331. When the support block is inserted into the fixing groove, the bottom of the fixing part abuts against the top surface of the bottom support rod and presses down on the bottom support rod. At this time, the side wall of the fixing part slides and presses against the locking block. The locking block moves outward until the bottom support rod is fully in place and abuts against the bottom of the fixing groove. At this point, the second telescopic spring retracts into the second receiving groove, and the side wall of the side support rod abuts against the side wall of the fixing part. The tops of both sides of the fixing part are located below the locking block. The locking block automatically moves towards the top of the fixing part under the action of the first telescopic spring until it abuts against the top of the fixing part, thus locking the support block and quickly fixing the support block to the fixing seat. When it is necessary to remove and replace the support block, pull the locking blocks on both sides at the same time to make the locking blocks leave the top of the fixing part. At this time, the second telescopic spring acts to automatically pop up the bottom support rod, causing the bottom support rod to drive the support block to pop up. At this time, the support block can be removed, realizing the quick removal of the support block. The operation is simple, more labor-saving and convenient. The setting of the limit block can limit the maximum outward tilt angle of the side support rod, avoiding excessive outward tilt of the side support rod, which would cause the bottom support rod to rotate too much and make it impossible for the support block to press down on the bottom support rod, affecting the installation efficiency of the support block.

[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
