[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A positioning structure of a slow wire cutting machine tool comprises a machine tool body 1, the top of the machine tool body 1 is provided with two positioning mechanisms 2 for clamping parts, and the bottom of the machine tool body 1 is provided with a collecting component 3 for collecting debris;

[0031] The positioning mechanism 2 includes a slide 201, a motor 202, a screw 203, a clamp 204, a cross plate 205, an electric cylinder 206 and a pressure plate 207. The slide 201 is opened at the top of the machine tool body 1, the motor 202 is bolted to the outer wall of the machine tool body 1, the screw 203 is fixedly connected to the output end of the motor 202, the clamp 204 is threadedly connected to the outside of the screw 203, the cross plate 205 is bolted to the outer wall of the clamp 204, the electric cylinder 206 is bolted to the outer wall of the clamp 204, the pressure plate 207 is fixedly connected to the output end of the electric cylinder 206, and one end of the screw 203 extends to the inside of the slide 201 and is rotatably connected to the slide 201.

[0032] Specifically, Figure 3 As shown, a plurality of baffles 4 are welded inside the slide groove 201 to reduce the probability of debris contacting the screw rod 203 , and one end of the baffle 4 passes through the clamping plate 204 and is welded to the side wall of the slide groove 201 .

[0033] Specifically, Figure 3 As shown, a chip removal groove 5 is provided at the bottom of the machine tool body 1 to prevent debris from accumulating inside the chute 201 , and the chip removal groove 5 is communicated with the outside of the machine tool body 1 .

[0034] Specifically, Figure 3 As shown, a triangular plate 6 for cleaning debris is bolted to the outer wall of the clamping plate 204 , and the bottom of the triangular plate 6 is tightly fitted with the top of the machine tool body 1 .

[0035] Specifically, Figure 3 As shown, a collecting cavity 7 for collecting debris is provided on the outer wall of the triangular plate 6, and the number of the collecting cavities 7 is several and evenly distributed.

[0036] Specifically, Figure 3 As shown, a protective pad 8 is bonded to the top of the horizontal plate 205 to prevent the parts from being deformed.

[0037] When in use, connect the motor 202 to the external power supply, and then start the motor 202. The motor 202 drives the screw rod 203 to rotate. When the screw rod 203 rotates, it will drive the clamping plate 204 to move to one side. When the clamping plate 204 moves to the appropriate position, the part can be placed on the cross plate 205, and then the electric cylinder 206 is started. The electric cylinder 206 drives the pressure plate 207 to descend, thereby positioning the part. At this time, the protective pad 8 can protect the part to prevent the part from deformation. When the clamping plate 204 moves, the clamping plate 204 will slide along the slide groove 201 and the baffle 4. At this time, the baffle 4 can reduce the probability of debris entering the inside of the slide groove 201. If debris accidentally enters the inside of the slide groove 201, the debris will also be discharged from the chip discharge groove 5, and then the triangle plate 6 will also move with the clamping plate 204. The triangle plate 6 can scrape up the debris on the top of the machine tool body 1, thereby cleaning the top of the machine tool body 1.

[0038] Specifically, Figure 3 and Figure 5 As shown, the collecting component 3 includes a connecting groove 301, a convex groove 302 and a collecting frame 303. The connecting groove 301 is opened at the top of the machine tool body 1, the convex groove 302 is opened at the bottom of the machine tool body 1, and the collecting frame 303 is slidably connected to the inside of the convex groove 302. The connecting groove 301 is connected to the collecting frame 303.

[0039] Specifically, Figure 4 As shown, a first magnet 9 is bonded to the bottom of the machine tool body 1 , a second magnet 10 is bonded to the outer wall of the collection frame 303 , and the second magnet 10 is magnetically connected to the first magnet 9 .

[0040] When the clamp 204 drives the triangular plate 6 to move, the triangular plate 6 will push the debris into the connecting groove 301, and then fall into the collection frame 303. Then, when the interior of the collection frame 303 is full, the collection frame 303 can be pulled out, and then the debris inside it can be taken out, and then the collection frame 303 can be pushed in again, and then the second magnet 10 and the first magnet 9 are adsorbed to fix the collection frame 303.

[0041] By adopting the above technical solution, the problem that the positioning structure of an existing wire-cutting machine tool is solved, in which the two clamping plates 204 are moved in opposite directions by the bidirectional screw 203 during use, thereby clamping the parts, but this method can only clamp the parts in the central part of the bidirectional screw 203, which has certain limitations.

[0042] Working principle: When in use, connect the motor 202 to an external power source, and then start the motor 202. The motor 202 drives the screw rod 203 to rotate. When the screw rod 203 rotates, it drives the clamping plate 204 to move to one side. When the clamping plate 204 moves to a suitable position, the part can be placed on the cross plate 205, and then the electric cylinder 206 is started. The electric cylinder 206 drives the pressure plate 207 to descend, so as to position the part. At this time, the protective pad 8 can protect the part to prevent the part from deformation. When the clamping plate 204 moves, the clamping plate 204 will slide along the slide groove 201 and the baffle 4. At this time, the baffle 4 can reduce the probability of debris entering the slide groove 201. If any debris accidentally enters the interior of the slide groove 201, the debris will also be discharged from the chip discharge groove 5, and then the triangular plate 6 will also move with the clamping plate 204. The triangular plate 6 can scrape up the debris on the top of the machine tool body 1, thereby cleaning the top of the machine tool body 1. When the clamping plate 204 drives the triangular plate 6 to move, the triangular plate 6 will push the debris into the interior of the connecting groove 301, and then fall into the interior of the collection frame 303. Then, when the interior of the collection frame 303 is full, the collection frame 303 can be pulled out, and then the debris inside it can be taken out, and then the collection frame 303 can be pushed in again, and then the second magnet 10 and the first magnet 9 are adsorbed, so that the collection frame 303 is fixed.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
