Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-5This utility model provides a wire cutting machining positioning device, including a positioning base 1. The inner wall of the positioning base 1 has a through groove, and a positioning device 3 is installed in the through groove. The positioning device 3 passes through the positioning base 1 and is connected to a motor 2. The motor 2 is installed on the side wall of the positioning base 1. A rotating shaft 7 is rotatably installed on the inner wall of the base 1. A connecting block 4 is fixedly installed at the lower end of the rotating shaft 7. The connecting block 4 is connected to the main body of the equipment. A snap-fit ​​structure 5 is fixedly installed on the inner wall of the connecting block 4. Through holes 6 are symmetrically opened on the upper and lower sides of the positioning base 1. The two through holes 6 are located on both sides of the rotating shaft 7, and the snap-fit ​​structure 5 is snap-fitted to one of the through holes 6. A vacuum suction cup 8 is fixedly installed on the surface of the positioning base 1. An air valve 9 is fixedly connected to the lower side wall of the vacuum suction cup 8, and the air valve 9 passes through the positioning base 1.

[0016] The connecting block 4 is connected to the main body of the wire cutting equipment, facilitating the connection of the positioning base 1. The rotating shaft 7 allows the positioning base 1 to rotate, and the locking structure 5, in conjunction with the through hole 6, fixes its position, thus determining whether to use the positioning device 3 or the vacuum suction cup 8. The positioning device 3, in conjunction with the motor 2, allows for fine-tuning of its horizontal position, ensuring a wide range of applicability. It also optimizes the clamping force distribution by employing multi-point uniform clamping, avoiding localized stress concentration and facilitating the disassembly and replacement of fixtures of different specifications, further ensuring its applicability. The vacuum suction cup 8, in conjunction with the air valve 9 (which connects to an external air passage), is suitable for thin sheet materials, ensuring effective adsorption and positioning while minimizing workpiece deformation. It is convenient to use and highly practical.

[0017] The positioning device 3 includes an adjusting block 31, which is inserted into the through groove in the inner wall of the positioning base 1. A screw 32 is screwed onto the inner wall of the adjusting block 31. One end of the screw 32 is rotatably connected to the inner wall of the positioning base 1, and the other end of the screw 32 passes through the positioning base 1 and is connected to the motor shaft of the motor 2. A mounting base 33 is mounted on the surface of the adjusting block 31 by screws, and a pneumatic positioning clamp 34 is fixedly mounted on the surface of the mounting base 33.

[0018] When the positioning device 3 is needed, first turn on the motor 2 as needed to drive the screw 32 to rotate. Based on the screw connection between the screw 32 and the adjusting block 31, and the limiting effect of the adjusting block through the through groove in the inner wall of the positioning base 1, the adjusting block 31 will move horizontally as the screw 32 rotates. After adjusting to the appropriate position, use the pneumatic positioning fixture 34 to clamp the workpiece to ensure multi-point uniform clamping and avoid local stress concentration. At the same time, the mounting base 33 can be removed with screws to replace the fixture, which has a wide range of applications.

[0019] The snap-fit ​​structure 5 includes a hydraulic cylinder 51, which is fixedly mounted on the inner wall of the connecting block 4. The piston rod end of the hydraulic cylinder 51 is fixedly mounted with an insert rod 52, which is inserted into one of the through holes 6.

[0020] Once the position of the positioning base 1 is determined, the hydraulic cylinder 51 is activated to control the piston rod to move upward and drive the insertion rod 52 to be inserted into the corresponding through hole 6, thereby completing the restriction and fixation of the positioning base 1.
