Description

Technical Field

[0001] The invention relates to the technical field of devices for sawing machines, in particular to an auxiliary locking and positioning structure for materials on sawing machines. Background Art

[0002] A sawing machine is a kind of equipment widely used in the metal processing industry. It is mainly used for cutting metal materials. Its working principle is to use a saw blade or saw blade to cut the workpiece. The cutting of the material is completed by moving the sawing machine's worktable or the movement of the saw blade / saw blade. The types of sawing machines include band sawing machines, circular sawing machines, etc. The corresponding sawing machine type is selected according to different processing needs. During the operation of the sawing machine, the auxiliary locking and positioning structure plays a vital role. Its main function is to ensure that the material to be processed can be accurately and firmly fixed on the sawing machine before cutting, so as to avoid cutting errors or safety accidents caused by material movement during the cutting process. The structure usually includes a clamping device, a moving mechanism and an adjustment component to adapt to the processing of materials of different sizes and shapes. Demand; Although the existing auxiliary locking and positioning structures of sawing machines can meet the needs of industrial production to a certain extent, they generally have some significant disadvantages. First, the design of many auxiliary locking and positioning structures is too complicated, including multiple moving parts and adjustment mechanisms, which not only increases the manufacturing cost of the equipment, but also increases the difficulty of maintenance. At the same time, the complex structure is more prone to failure. Secondly, after the traditional auxiliary locking and positioning structure clamps the object for one cutting, if the object needs to be pushed forward for another cutting, the operation process is cumbersome, and the position of the object needs to be adjusted through multiple steps, and it takes a long time to complete the positioning. This inefficient operation method greatly reduces the overall production efficiency, which is not conducive to the modern industrial requirements of rapid production. Summary of the invention

[0029] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0030] The second motor 75 is turned off, and the rotation of the worm gear 73 and the worm gear 76 can be used to prevent the rotating ring 72 from rotating, thereby preventing the clamping force on the workpiece from being reduced. The third slider 15 is pulled upward, and the upward sliding of the third slider 15 can drive the second clamping block 16 to move upward and squeeze the spring 14 to generate a rotation. The second block 16 is elastically deformed until the second block 16 is completely out of the inner cavity of the positioning groove 2, and the blocking plate 11 is slid forward and backward according to the scale line on the outer wall of the guide rod 4 until the blocking plate 11 is slid to an appropriate distance from the front side of the positioning cylinder 71, and the third slider 15 is released. The second block 16 can be pushed to move into the inner cavity of the positioning groove 2 under the elastic force of the spring 14, so that the blocking plate 11 can be positioned by the cooperation between the second block 16 and the first block 3 to prevent the blocking plate 11 from sliding forward, and the first motor 5 is started. The output end of the first motor 5 drives the screw 6 to rotate. The rotational force generated by the rotation of the screw 6 can prompt the push plate 9 to move forward until the front side of the push plate 9 contacts the rear end of the workpiece, so that the push plate 9 can push the workpiece forward. While the workpiece moves forward, the rubber roller 710 can be prompted to rotate until the front end of the workpiece contacts the rear side of the blocking plate 11, so that the workpiece can be prevented from moving forward and backward during cutting, so that the workpiece can be cut by the sawing machine.

[0031] In summary, the device is simple in design and the operation process is simplified accordingly, which reduces the skill requirements of operators, reduces training costs and reduces the manufacturing cost of equipment, while reducing maintenance difficulty and failure rate. In addition, the device can quickly and accurately fix the materials to be processed, avoiding cumbersome operation processes, thereby improving overall production efficiency.
