[0002] The wire electrical discharge machine is a common electro - machining mechanical equipment, which is often used for the processing of stamping dies and the cutting of metals. When the wire electrical discharge machine cuts metal plates, it is necessary to position the plates. The traditional positioning method is to install a pressing plate on the crossbeam in the working area of the wire cutting machine with bolts. When positioning, the plate to be cut is placed on the crossbeam, and then the bolts are tightened so that the pressing plate clamps on one side edge of the plate. During the wire cutting process, the plate is very easy to deflect, resulting in cutting misalignment and wasting the cut plate.
[0003] Therefore, we design a wire cutting positioning device here. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4 , in this implementation: The wire cutting positioning device includes a rectangular frame 1, which is fixedly installed on the crossbeam of the working area of the wire cutting machine. A crossbeam 2 is fixedly installed between the left and right inner sidewalls of the rectangular frame 1. A pair of transverse sliding rails 3 are installed on the front and rear sidewalls of the crossbeam 2. Two U-shaped sliders 4 are slidably installed on the sliding rails 3. The two U-shaped sliders 4 are symmetric about the midline of the crossbeam 2. Clamping structures 5 are installed on the tops of the two U-shaped sliders 4. A second threaded rod 6 is rotatably installed between the left and right inner sidewalls of the rectangular frame 1. Two threaded sleeves 7 are sleeved on the second threaded rod 6. The two threaded sleeves 7 are respectively fixed to the two U-shaped sliders 4. The thread directions of the left and right halves of the second threaded rod 6 are opposite. The two threaded sleeves 7 are respectively matched with the threads of the left and right halves of the second threaded rod 6. By rotating the second threaded rod 6 forward or backward, through the cooperation of the second threaded rod 6 and the two threaded sleeves 7, the two U-shaped sliders 4 can be controlled to move towards the middle or towards both sides at the same time, so as to control the two clamping structures 5 to approach or move away from each other. By controlling the two clamping structures 5 to approach each other, the to-be-cut plate can be limited from both sides. The cross-section of the crossbeam 2 is an inverted U shape. The second threaded rod 6 and the threaded sleeves 7 are both located in the U-shaped groove at the bottom of the crossbeam 2. By hiding the second threaded rod 6 and the threaded sleeves 7 inside the crossbeam 2, it is possible to prevent debris from falling onto the second threaded rod 6 during the operation of the wire cutting machine, which may affect the cooperation between the second threaded rod 6 and the threaded sleeves 7.
[0021] Please refer to Figure 3 , the right end of the second threaded rod 6 passes through the sidewall of the rectangular frame 1 and is installed with a worm gear 8. A worm 9 is rotatably installed on the right sidewall of the rectangular frame 1 through a bearing seat. The worm 9 is matched with the worm gear 8. A protective cover 10 is installed on the right side of the rectangular frame 1. The worm gear 8 and the worm 9 are both located inside the protective cover 10. The front end of the worm 9 passes through the sidewall of the protective cover 10 and is fixedly installed with a second knob 11. By rotating the second knob 11 forward or backward, through the cooperation of the worm gear 8 and the worm 9, the second threaded rod 6 can be driven to rotate forward or backward. The protective cover 10 can play a protective role for the worm gear 8 and the worm 9, preventing dust or debris from falling onto the worm gear 8 and the worm 9, which may affect the cooperation between the two.
[0022] Please refer to Figure 4, the clamping structure 5 includes a U-shaped plate 5-1, a pressing plate 5-2, a first threaded rod 5-3 and a first knob 5-4. The U-shaped opening of the U-shaped plate 5-1 faces the side. The U-shaped plate 5-1 is fixedly installed on the top of the U-shaped slider 4. The pressing plate 5-2 is located between the upper cross plate and the lower cross plate of the U-shaped plate 5-1. A threaded through hole is provided on the upper cross plate of the U-shaped plate 5-1. The first threaded rod 5-3 is matched with the threaded through hole. The bottom end of the first threaded rod 5-3 is rotatably installed on the top of the pressing plate 5-2. The first knob 5-4 is fixedly installed on the top end of the first threaded rod 5-3. By rotating the first knob 5-4, through the cooperation of the first threaded rod 5-3 and the threaded through hole on the U-shaped plate 5-1, the up and down movement of the pressing plate 5-2 can be controlled. Through the cooperation of the pressing plate 5-2 and the lower cross plate of the U-shaped plate 5-1, the to-be-cut plate is clamped and fixed. The U-shaped openings of the U-shaped plates 5-1 in the two clamping structures 5 face each other. Anti-slip patterns are provided on the top of the lower cross plate of the U-shaped plate 5-1 and the bottom of the pressing plate 5-2.
[0023] The working principle and usage process of the present utility model: When using this wire cutting positioning device, rotate the second knob 11. Through the cooperation of the worm gear 8 and the worm 9, drive the second threaded rod 6 to rotate. Then, through the cooperation of the second threaded rod 6 and the threaded cylinder 7, control the two clamping structures 5 to approach each other until the distance between the vertical plates of the U-shaped plates 5-1 in the two clamping structures is slightly larger than the width of the to-be-cut plate. Insert the plate between the U-shaped openings of the U-shaped plates 5-1 on both sides. Then continue to rotate the second knob 11 until the vertical plates of the U-shaped plates 5-1 on both sides clamp on both sides of the to-be-cut plate, thereby limiting the plate and preventing the plate from shifting during the subsequent cutting process. Finally, rotate the first knobs 5-4 of the two clamping structures 5. Through the cooperation of the pressing plate 5-2 and the lower cross plate of the U-shaped plate 5-1, the to-be-cut plate is clamped and fixed.
[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
