However, existing automatic wire threading devices cannot accurately position the wire end (i.e., the end position of the electrode wire) inside the wire threading tube during the wire threading process, so it is difficult to ensure that the end of the electrode wire is accurately transported to the predetermined clamping position. Utility Model Content

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , Figure 2 As shown, an embodiment of this utility model provides an automatic wire cutting head position detection device, including a detection plate 1 and a drive mechanism 2. Both the detection plate 1 and the drive mechanism 2 are installed on the wire cutting device 5 of the wire cutting machine.
[0024] The wire threading device 5 is equipped with a wire threading tube 3, which has a guide channel 31 for the electrode wire to pass through. The detection plate 1 is movably inserted into the guide channel 31 and is used to connect to the electrical control system of the wire cutting machine. The drive mechanism 2 is connected to the detection plate 1 and is used to drive the detection plate 1 to reciprocate between the detection position and the yielding position.
[0025] The electrode wires in the detection plate 1 and guide channel 31 can be connected to the detection discharge module and detection power receiving module of the wire EDM machine's electrical control system, respectively. When the detection plate 1 moves to the detection position, the electrode wires in the guide channel 31 connect to the detection plate 1, activating the detection discharge module and detection power receiving module in the electrical control system used to detect the position of the electrode wire ends in the guide channel 31, thereby detecting and positioning the position of the electrode wire ends in the guide channel 31. Alternatively, a position sensor electrically connected to the wire EDM machine's electrical control system can be installed on the detection plate 1. The position sensor detects the position of the electrode wire ends in the guide channel 31 and transmits the detected position information to the wire EDM machine's electrical control system.
[0026] After the test is completed, the test plate 1 can be moved to a clearance position that does not obstruct the passage of the electrode wire, allowing the electrode wire to pass normally and ensuring that the end of the electrode wire can be accurately delivered to the predetermined clamping position. It can be understood that the test plate 1 and the drive mechanism 2 can be directly installed on the wire threading tube 3 (as shown in the embodiment of this utility model), or they can be set on the side of the wire threading tube 3, and the test plate 1 can be inserted or withdrawn by the drive mechanism 2 when testing or clearance is required.
[0027] Specifically, such as Figure 3 As shown, the threading tube 3 in this embodiment of the present invention includes a first tube segment 32 and a second tube segment 33 that are intermittently arranged. The first tube segment 32 and the second tube segment 33 are connected and conductive through a connector 34. The connector 34 has a socket for inserting a detection plate 1. The detection plate 1 is movably inserted between the first tube segment 32 and the second tube segment 33 through the socket.
[0028] Furthermore, a clearance hole 11 can be opened on the detection plate 1. When the detection plate 1 moves to the clearance position, the clearance hole 11 is aligned with the guide channel 31, which will not obstruct the passage of the electrode wire, but also fill the gap between the first tube segment 32 and the second tube segment 33, so as to avoid the electrode wire getting stuck when passing between the first tube segment 32 and the second tube segment 33.
[0029] As an optional implementation method, such as Figure 2 , Figure 3 As shown, the driving mechanism 2 in this embodiment of the present invention includes a guide 21, a limiting member 22, a moving member 23, a first force-applying member 24, and a second force-applying member 25.
[0030] One end of the guide member 21 is connected to the connector 34, and the limiting member 22 is installed at the other end of the guide member 21. The movable member 23 is slidably sleeved on the guide member 21, and the detection plate 1 is installed on the movable member 23. The first force-applying member 24 is used to apply a force to the movable member 23 to move the detection plate 1 toward the yielding position, and the second force-applying member 25 is used to apply a force to the movable member 23 to move the detection plate 1 toward the detection position. The movable member 23 can reciprocate under the action of the first force-applying member 24 and the second force-applying member 25, thereby driving the detection plate 1 to reciprocate between the detection position and the yielding position.
[0031] For reference, the first force-applying component 24 can be a spring or a magnetic assembly. When the first force-applying component 24 is a spring, one end of the spring is connected to the moving component 23, and the other end is connected to the connecting component 34 or the limiting component 22. When the first force-applying component 24 is a magnetic assembly, the magnetic assembly may include two attracting magnetic blocks or two repulsive magnetic blocks. The two attracting magnetic blocks can be respectively installed to the limiting component 22 and the moving component 23, and the two repulsive magnetic blocks can be respectively installed to the moving component 23 and the connecting component 34.
[0032] The wire threading tube 3 is equipped with a drive source 4 for driving it to reciprocate along its own length. Under the drive of the drive source 4, the wire threading tube 3 can reciprocate in a direction that is closer to or farther away from the winding drum (not shown in the figure) so as to deliver the end of the electrode wire to the clamping position on the outer wall of the winding drum for clamping.
[0033] As an optional implementation, in this embodiment of the present invention, a push plate is used as the second force-applying member 25. The push plate is arranged on one side of the moving member 23 along the length direction of the threading tube 3, so that when the threading tube 3 moves, the moving member 23 can reciprocate along with the connecting member 34 in the direction of approaching or moving away from the push plate, thereby causing the push plate to press against or separate from the moving member 23.
[0034] When the moving member 23 moves to press against the push plate, the push plate applies a force to the moving member 23, causing the detection plate 1 to move towards the detection position. When the moving member 23 moves to separate from the push plate, the push plate no longer applies force to the moving member 23, and the first force-applying member 24 applies a force to the moving member 23, causing the detection plate 1 to move towards the yielding position. By utilizing the displacement of the wire-threading tube 3 itself to automatically switch the detection plate 1 between the detection position and the yielding position, the driving program of the detection plate 1 can be effectively simplified.
[0035] Furthermore, a pressing part 231 for pressing and engaging with the pressing plate and a guide part 232 extending and guiding towards the pressing part 231 can be provided on the movable member 23 to facilitate the pressing of the pressing plate and the movable member 23.
[0036] It is understandable that the drive mechanism 2 can also adopt common reciprocating motion structures such as hydraulic cylinders, air cylinders, linear motors, cam mechanisms, gear and rack mechanisms, and linkage mechanisms, as long as it can drive the detection plate 1 to move back and forth between the detection position and the yielding position. Examples will not be given here.
[0037] Working process: In the initial state, the detection board 1 is in the position as follows: Figure 3 The detection position shown indicates that the detection plate 1, in cooperation with the electrical control system of the wire cutting machine, can detect the position of the electrode wire end in the guide channel 31, so as to accurately locate the position of the electrode wire end.
[0038] After the test is completed, the wire threading tube 3 moves towards the winding drum to a predetermined position under the drive of the drive source 4. The moving part 23 then moves away from the push plate until it separates from the push plate. The detection plate 1 automatically moves to the yielding position under the action of the first force application part 24, so that the end of the electrode wire can be accurately delivered to the clamping position on the outer wall of the winding drum through the wire threading tube 3 for clamping.

The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this utility model. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
