However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0029] This application discloses a wire cutting automatic wire clamping device. By means of the pressing mechanism, the first clamping piece is installed on the wire winding cylinder, and the problem in the prior art that the space is small when the clamping piece and the outer wall of the wire winding cylinder are separated, and it is easy to fail in clamping the electrode wire is solved.

[0030] As Figure 1 shown, the wire cutting automatic wire clamping device 3 is installed on the wire winding cylinder 1 and is arranged on one side of the wire feeding device 2.

[0031] In the first embodiment, as Figure 2 shown, the wire cutting automatic wire clamping device 3 includes: a pressing mechanism 31 and a first clamping piece 32.

[0032] The pressing mechanism 31 is installed on the wire winding cylinder 1, and the first clamping piece 32 is installed on the pressing mechanism 31.

[0033] The pressing mechanism 31 is used to apply a force towards the wire winding cylinder 1 to the first clamping piece 32, so that the first clamping piece 32 and the wire winding cylinder 1 are in a pressed state.

[0034] As Figure 2 and 3 shown, when the wire feeding device 2 extends to a predetermined position between the first clamping piece 32 and the wire winding cylinder 1, the first clamping piece 32 and the wire winding cylinder 1 are in a separated state.

[0035] Regarding the first clamping piece 32, as Figure 3 shown, the first clamping piece 32 is provided with a first guiding portion, and the position of the first guiding portion is matched with the wire feeding device 2. The first guiding portion can be an inclined surface structure or an arc surface structure. As Figure 2 and 3 shown, the first guiding portion is an inclined surface structure.

[0036] By the cooperation of the first guiding portion and the arc surface of the wire winding cylinder 1, the wire feeding device 2 can enter between the first clamping piece 32 and the wire winding cylinder 1 more smoothly.

[0037] As Figure 2 and 3 shown, the first clamping piece 32 further includes: a stopping portion 321.

[0038] The stopping portion 321 extends a predetermined distance from the first clamping piece 32 towards the wire winding cylinder 1, and it is used to stop the electrode wire 4 within a predetermined area. As Figure 1 shown, the wire cutting automatic wire clamping device 3 is arranged at one end of the outer wall of the wire winding cylinder 1, and the stopping portion 321 is arranged at the position of the other end of the first clamping piece 32 close to the outer wall of the wire winding cylinder 1 to prevent the electrode wire 4 from entering the cutting area of the wire winding cylinder 1.

[0039] As Figure 2 and 3 shown, the stopping portion 321 is a plate-like structure arranged on one side of the first clamping piece 32. Two plate-like stopping portions 321 can also be arranged on both sides of the first clamping piece 32, and the wire winding cylinder 1 is provided with through holes matched with the guiding member 311, the acting member 312 and the stopping portion 321.

[0040] Regarding the pressing mechanism 31, as Figure 3 shown, the pressing mechanism 31 includes: a guiding member 311, an acting member 312, a power element 313 and a limiting member 314.

[0041] The guiding member 311 is installed on the wire winding cylinder 1, the acting member 312 is installed on the guiding member 311 and passes through the wire winding cylinder 1, the first clamping piece 32 is installed at one end of the acting member 312, the limiting member 314 is installed at the other end of the acting member 312, one end of the power element 313 is connected to the guiding member 311 or the wire winding cylinder 1, and the other end of the power element 313 is connected to the limiting member 314.

[0042] Through the cooperation of the guiding member 311, the power element 313 and the limiting member 314, the actuating member 312 transmits the elastic force of the power element 313 to the first clamping piece 32 to form a pressing force between the first clamping piece 32 and the wire winding cylinder 1 or the second clamping piece 33.

[0043] As Figure 1 shown, two pressing mechanisms 31 are provided. When the second clamping piece 33 is provided, one end of the guiding member 311 and / or the power element 313 can be connected to the second clamping piece 33.

[0044] By arranging the actuating member 312 to pass through the wire winding cylinder 1, the guiding member 311, the power element 313 and the limiting member 314 can be arranged inside the wire winding cylinder 1, greatly reducing the volume of the wire clamping device 3 outside the wire winding cylinder 1 and reducing the eccentricity distance of the wire clamping device 3.

[0045] In this embodiment, the power element 313 is a spring or a magnetic assembly.

[0046] When the power element 313 is a magnetic assembly, the magnetic assembly includes a first magnetic block and a second magnetic block. The first magnetic block is connected to the guiding member 311 or the wire winding cylinder 1, the second magnetic block is connected to the limiting member 314, and the first magnetic block and the second magnetic block are arranged in a mutually repulsive manner.

[0047] Among them, the guiding member 311 can be a linear bearing or a slider, etc., the actuating member 312 can be a connecting shaft or a connecting rod, etc., and the limiting member 314 can be a nut, a welding piece or a lateral convex structure of the actuating member 312. As Figure 3 shown, the guiding member 311 is a linear bearing, the actuating member 312 is a connecting shaft, the limiting member 314 is a nut, and the power element 313 is a spring.

[0048] Second embodiment, a second clamping piece 33 is provided on the basis of the first embodiment.

[0049] As Figure 2 and 3 shown, the wire cutting automatic wire clamping device 3 further includes: a second clamping piece 33.

[0050] The second clamping piece 33 is installed on the wire winding cylinder 1, and the second clamping piece 33 is arranged between the wire winding cylinder 1 and the first clamping piece 32.

[0051] The pressing mechanism 31 is used to apply a force to the first clamping piece 32 towards the second clamping piece 33, so that the first clamping piece 32 and the second clamping piece 33 are in a pressed state.

[0052] When the wire feeding device 2 extends to a predetermined position between the first clamping piece 32 and the second clamping piece 33, the first clamping piece 32 and the second clamping piece 33 are in a separated state.

[0053] In this embodiment, the adjacent sides of the first clamping piece 32 and the second clamping piece 33 are mating planar structures, arc-shaped structures, or toothed structures. For example, Figure 2 and 3 as shown in Figure 2 and 3 , the adjacent sides of the first clamping piece 32 and the second clamping piece 33 are mating planar structures.

[0054] Through the cooperation of the first clamping piece 32 and the second clamping piece 33, the surface shape for clamping the electrode wire 4 can be changed, so that the clamping surface is not limited to the arc-shaped structure of the wire winding cylinder 1, and the shape of the clamping surface can be set according to the actual application situation, thereby improving the clamping force on the electrode wire 4.

[0055] For example, Figure 2 and 3 as shown in Figure 2 and 3 , the second clamping piece 33 is provided with a second guiding portion, and the position of the second guiding portion cooperates with the wire feeding device 2.

[0056] The first guiding portion and the second guiding portion can be inclined plane structures or arc-shaped structures.

[0057] For example, Figure 3 as shown in Figure 3 , the cooperating positions of the first clamping piece 32 and the second clamping piece 33 with the wire feeding device 2. For example, Figure 2 and 3 as shown in Figure 2 and 3 , the first guiding portion is an inclined plane structure and the second guiding portion is an arc-shaped structure.

[0058] Through the cooperation of the arc surface of the second guiding portion and the first clamping piece 32, the wire feeding device 2 can enter more smoothly between the first clamping piece 32 and the wire winding cylinder 1 or between the first clamping piece 32 and the second clamping piece 33.

[0059] Working method: The driving member of the wire feeding device 2 extends the wire feeding tube between the first clamping piece 32 and the wire winding cylinder 1. When the wire feeding device 2 extends to a predetermined position between the first clamping piece 32 and the wire winding cylinder 1, the first clamping piece 32 and the wire winding cylinder 1 are in a separated state as shown in Figure 2 and 3 as shown in Figure 2 and 3 .

[0060] Then, as shown in Figure 2 the wire feeding device 2 transports the electrode wire 4 from the wire feeding tube between the first clamping piece 32 and the second clamping piece 33. Then the wire feeding tube exits between the first clamping piece 32 and the second clamping piece 33, leaving the electrode wire 4 between the first clamping piece 32 and the second clamping piece 33.

[0061] During the process of the wire feeding tube withdrawing from between the first clamping piece 32 and the second clamping piece 33, the pressing mechanism 31 drives the first clamping piece 32 to move towards the second clamping piece 33, so that the first clamping piece 32 and the second clamping piece 33 are in a pressed state, clamping the electrode wire 4 between the first clamping piece 32 and the second clamping piece 33. Through the cooperation of the pressing mechanism 31, the first clamping piece and the wire feeding device 2, automatic wire clamping is achieved. During this process, the space for clamping the electrode wire 4 between the first clamping piece 32 and the second clamping piece 33 can be adjusted by the outer diameter dimension of the wire feeding tube, greatly increasing the success rate of clamping the motor wire 4. Among them, the electrode wire 4 can be a wire cutting electrode wire such as a copper wire or a molybdenum wire.

[0062] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation to the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
