Description

Technical Field

[0001] The utility model belongs to the technical field related to wire cutting machines, and particularly relates to a rapid positioning mechanism for wire cutting machines. Background Art

[0002] In modern manufacturing, accurate material positioning is crucial to improving production efficiency and cutting quality. Especially when using wire-cutting machines for high-precision cutting, ensuring stable workpiece positioning not only reduces machining errors but also effectively improves production efficiency. Traditional manual positioning methods are often time-consuming and labor-intensive, and it is difficult to ensure machining accuracy. Therefore, the development of efficient and rapid positioning mechanisms has become an important direction for improving the performance of wire-cutting machines.

[0003] The rapid positioning mechanism for wire-cutting machines is designed to enable fast and accurate workpiece positioning. This mechanism, through the combination of a track-mounted bracket and a movable positioning frame, enables rapid adjustment and fixation of the workpiece's position. The track-mounted bracket provides a stable reference surface, while the movable positioning frame, by aligning with the T-slot on the track-mounted bracket, enables precise horizontal movement of the positioning frame. This design allows the workpiece to be accurately placed and secured in place in a short period of time, significantly improving machining flexibility and efficiency. Furthermore, the internal adjustment screw holes and locking bolts further ensure positioning accuracy and stability.

[0004] However, the rapid positioning mechanism of the wire cutting machine is mainly used to position and fix the material that needs wire cutting. After the material is positioned and fixed by the rapid positioning mechanism, the positioned and fixed material can be wire-cut to avoid displacement and shaking of the material during wire cutting. However, when using the rapid positioning mechanism to position and fix the material, the material needs to be placed in the position where it needs to be positioned and fixed, and then the rapid positioning mechanism is operated to position and fix the material. In the process of positioning and fixing the material, the operator needs to maintain the position height and angle of the material with one hand, and the other hand needs to operate the rapid positioning mechanism to position and fix the material. This operation method is likely to cause position deviation when the material is finally positioned, and will also increase the operation steps and difficulty of the rapid positioning mechanism.

[0030] like Figure 1 、 Figure 6 and Figure 7As shown, when the plate-like material needs to be positioned and fixed by the quick positioning mechanism, in order to position and fix the plate-like material more quickly and readily, it is necessary to use the material pre-placing device 4 to place the plate-like material to the position where it needs to be positioned, so as to facilitate the operator to operate and use the positioning mechanism more accurately and quickly. Specifically, it is necessary to place the adjustment support bar 20 longitudinally on the right side of the L-shaped adjustment slide 19, and then directly slide the adjustment support bar 20 freely to the right into the L-shaped adjustment slide 19, and then determine the position where the plate-like material needs to be positioned, and slide the adjustment support bar 20 through the L-shaped adjustment slide 19 to the bottom of the position where the plate-like material needs to be placed, and then pull the adjustment support bar 20 back and forth to make the material pre-placing plate 22 at the top rear end of the adjustment support bar 20 fine-tune the position until the material pre-placing plate 22 is below the position where the plate-like material needs to be positioned and fixed, and then directly place the plate-like material on the material pre-placing plate 22 Then the operator can push the movable positioning frame A6 and the movable positioning frame B14 toward the plate material placed on the material pre-placing plate 22, until the movable positioning frame A6 and the movable positioning frame B14 are respectively positioned and clamped at both ends of the plate material, and then lock the movable positioning frame A6 and the movable positioning frame B14 to position and fix the plate material, and then slide the adjustment support bar 20 to the right until the adjustment support bar 20 slides out from the right end opening of the L-shaped adjustment slide 19, and then directly take out the adjustment support bar 20. After the plate material is placed on the material pre-placing plate 22, the operator does not need to pay attention to the plate material, but only needs to concentrate on sliding the two movable positioning frames and directly operate the movable positioning frames to clamp and position the plate material, so that there is no need to maintain the position and height of the plate material at all times when positioning and fixing the plate material, thereby making the rapid positioning mechanism faster, simpler and more accurate when operating.
