The artificial manual wire threading method has the following problems: low wire threading work efficiency, low automation degree of the wire threading process, and high labor cost. Summary of the Utility Model

The wire storage cylinder automatic wire threading device of this application includes a swing conduit and a driving component. The driving component can drive the swing conduit to move, so that the first end of the swing conduit can abut against the outer side wall of the wire storage cylinder. In this way, the electrode wire passing through the inner cavity of the swing conduit can penetrate between the outer side wall of the wire storage cylinder and the wire pressing member and be pressed by the wire pressing member, thus realizing the automatic wire threading operation of the machine tool, improving the wire threading work efficiency and reducing the labor cost.

The driving component can drive the swinging conduit to move, so that the first end of the swinging conduit can abut against the outer side wall of the wire storage cylinder, and can also separate the first end of the swinging conduit from the outer side wall of the wire storage cylinder. In this way, when the driving component drives the first end of the swinging conduit to abut against the outer side wall of the wire storage cylinder, the electrode wire passing through the first end of the swinging conduit and extending towards one side of the wire storage cylinder can penetrate between the outer side wall of the wire storage cylinder and the wire pressing member and be pressed and fixed to the outer side wall of the wire storage cylinder by the wire pressing member, thereby realizing the automatic wire threading operation of the device.

[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0022] Please refer to the Figures 1 to 7 schematic diagram of the structure of the automatic wire threading device for the wire storage cylinder according to the embodiment of the present application shown. As Figure 1 shown, the automatic wire threading device for the wire storage cylinder according to the embodiment of the present application includes a wire storage cylinder 1, a swing conduit 2 and a driving assembly 3. Among them, the wire storage cylinder 1 is used for winding the electrode wire 4, and a wire pressing member 5 is provided on the outer side wall of the wire storage cylinder 1. The wire pressing member 5 can press the electrode wire 4 that penetrates between the outer side wall of the wire storage cylinder 1 and the wire pressing member 5; the swing conduit 2 includes a first end 21 and a second end 22 that are oppositely distributed. The first end 21 is arranged close to the outer side wall of the wire storage cylinder 1, and the second end 22 is located at one end of the swing conduit 2 away from the wire storage cylinder 1. The inner cavity of the swing conduit 2 is used for the electrode wire 4 to pass through; the driving assembly 3 is connected to the swing conduit 2 and can drive the swing conduit 2 to move, so that the first end 21 can be switched between a state of being in contact with and separated from the outer side wall of the wire storage cylinder 1.

[0023] Specifically, the wire pressing member 5 can be set in the structural form of a pressing plate with a spring or a fastener, etc. The wire pressing member 5 is movably connected to the outer side wall of the wire storage cylinder 1. The wire pressing member 5 is in an open state when not pressing the electrode wire 4. When the electrode wire 4 is inserted between the outer side wall of the wire storage cylinder 1 and the wire pressing member 5, the wire pressing member 5 moves towards the outer side wall of the wire storage cylinder 1 so that the wire pressing member 5 presses and fixes the electrode wire 4 to the outer side wall of the wire storage cylinder 1. In the wire storage cylinder automatic wire threading device of the embodiment of the present application, a driving assembly 3 and a swinging catheter 2 are provided. The driving assembly 3 can drive the swinging catheter 2 to move, so that the first end 21 of the swinging catheter 2 can abut against the outer side wall of the wire storage cylinder 1 and can also separate the first end 21 of the swinging catheter 2 from the outer side wall of the wire storage cylinder 1. In this way, when the wire storage cylinder 1 rotates to a preset position, the wire pressing member 5 is in an open state relative to the wire storage cylinder 1. At this time, the driving assembly 3 drives the first end 21 of the swinging catheter 2 to abut against the outer side wall of the wire storage cylinder 1, so that the electrode wire 4 passing through the first end 21 of the swinging catheter 2 and extending towards one side of the wire storage cylinder 1 can penetrate between the outer side wall of the wire storage cylinder 1 and the wire pressing member 5 and be pressed by the wire pressing member 5, thereby realizing the automatic wire threading operation of the device. Through the automatic wire threading operation, the working efficiency of the wire threading process can be improved, the automation level of the wire threading process can be improved, and the labor cost can be reduced. Since the first end 21 of the swinging catheter 2 can be in close contact with the outer side wall of the wire storage cylinder 1 in a mutually abutting manner, and at the same time the swinging catheter 2 has a guiding effect on the electrode wire 4, the wire threading success rate of the wire storage cylinder automatic wire threading device of the present application is relatively high.

[0024] Moreover, after the wire pressing member 5 presses the electrode wire 4, the wire storage cylinder 1 can perform the operation of winding the electrode wire 4. At this time, the driving assembly 3 can drive the swinging catheter 2 to move, so that the first end 21 of the swinging catheter 2 can be separated from the outer side wall of the wire storage cylinder 1, thereby avoiding the swinging catheter 2 interfering with the wire storage operation of the wire storage cylinder 1.

[0025] In an exemplary embodiment, as Figures 1 to 7 shown, the wire storage cylinder automatic wire threading device further includes a bracket 6. The driving assembly 3 is installed on the bracket 6. The driving assembly 3 is configured to be able to drive the swinging catheter 2 to perform a swinging motion.

[0026] Specifically, the bracket 6 is used to support and connect the driving assembly 3. When the driving assembly 3 drives the swinging catheter 2 to perform a swinging motion, the first end 21 of the swinging catheter 2 can be swung to abut against the outer side wall of the wire storage cylinder 1 for performing the automatic wire threading operation, and after the wire threading action is completed, the first end 21 of the swinging catheter 2 can be swung to be separated from the outer side wall of the wire storage cylinder 1.

[0027] It can be understood that the driving assembly 3 can also be set to drive the swinging catheter 2 to perform other forms of motion, so that the first end 21 of the swinging catheter 2 can move between approaching and departing from the outer side wall of the wire storage cylinder 1, and the automatic wire threading operation can also be realized.

[0028] In an exemplary embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the driving assembly 3 includes a joint bearing 31, a cylinder 32, a first support seat 33, a first bearing 34 and a first support shaft 35. The joint bearing 31 is mounted to the bracket 6, the rod end of the joint bearing 31 is connected to the cylinder 32 so that the cylinder 32 is rotatably connected to the bracket 6, the output end of the cylinder 32 is connected to the first support seat 33, the telescopic movement of the cylinder 32 drives the first support seat 33 to move, the outer ring of the first bearing 34 is fixed to the first support seat 33, the inner ring of the first bearing 34 is sleeved on one end 351 of the first support shaft 35, and the other end 352 of the first support shaft 35 is connected to the swing guide tube 2.

[0029] Specifically, the end of the cylinder 32 facing away from the output end is rotatably connected to the bracket 6 via the joint bearing 31, and the output end of the cylinder 32 is rotatably connected to the swing guide tube 2 via the first support seat 33, the first bearing 34 and the first support shaft 35. In this way, when the output end of the cylinder 32 performs a telescopic movement, it can drive the swing guide tube 2 to swing.

[0030] exist Figure 1 In the embodiment shown, when the output end of the cylinder 32 is retracted, the cylinder 32 can swing relative to the bracket 6 and drive the first end 21 of the swing guide tube 2 to swing toward the outer side wall of the wire storage barrel 1. When the output end of the cylinder 32 is extended, the cylinder 32 can swing relative to the bracket 6 and drive the first end 21 of the swing guide tube 2 to swing away from the outer side wall of the wire storage barrel 1.

[0031] In an exemplary embodiment, Figure 6 As shown, the spherical plain bearing 31 is configured as a self-lubricating rod end spherical plain bearing.

[0032] like Figure 7 As shown, a support member 36 is provided at one end of the first support shaft 35 away from the first bearing 34 , and the support member 36 is provided with a first through hole 361 , and the swing guide tube 2 passes through the first through hole 361 .

[0033] Specifically, the self-lubricating rod end joint bearing is commonly known as the fisheye joint, which is a kind of joint bearing. The self-lubricating rod end joint bearing can withstand a large load. Since the self-lubricating rod end joint bearing is inlaid with a composite material on the outer spherical surface of its inner ring, the bearing can produce a self-lubricating effect during operation.

[0034] In an exemplary embodiment, Figure 1 , Figure 2 , Figures 4 to 7As shown, the automatic wire threading device of the wire storage cylinder further includes a rotational connection assembly 7; the driving assembly 3 is disposed near the second end 22, the rotational connection assembly 7 is located on the side of the driving assembly 3 away from the wire storage cylinder 1, the rotational connection assembly 7 is provided with a rotational axis 71, the second end 22 is connected to the rotational connection assembly 7, and the swing conduit 2 swings around the rotational axis 71.

[0035] Specifically, the rotational connection assembly 7 is connected to the second end 22 of the swing conduit 2. When the swing conduit 2 swings under the driving force of the driving assembly 3, it swings around the rotational axis 71 of the rotational connection assembly 7. The rotational connection assembly 7 defines the rotational axis 71 of the swing movement of the swing conduit 2. The rotational connection assembly 7 cooperates with the driving assembly 3 to make the swing movement process of the swing conduit 2 more stable, so that the swing conduit 2 can stably abut against the outer side wall of the wire storage cylinder 1, thereby improving the success rate of the automatic wire threading of the device.

[0036] In an exemplary embodiment, as Figure 1 、 Figure 2 、 Figures 4 to 7 shown, the rotational connection assembly 7 includes a second bearing seat 72, a second bearing 73, and a second support shaft 74.

[0037] The axis of the second bearing 73 is the rotational axis 71.

[0038] Specifically, the second support shaft 74 can form a rotational connection with the bracket 6 through the second bearing 73, so that the second support shaft 74 can cooperate with the swing movement of the swing conduit 2.

[0039] In an exemplary embodiment, as Figure 6 and Figure 7 shown, the second support shaft 74 is provided with a second through hole 743 extending in its radial direction at the end away from the second bearing 73, and the second end 22 of the swing conduit 2 is inserted through the second through hole 743 and fixedly connected to the second support shaft 74.

[0041] In an exemplary embodiment, as Figure 1 、 Figure 2 、 Figures 4 to 7As shown, it further includes a guiding component 8, which is arranged on the side of the rotating connection component 7 away from the wire storage cylinder 1. The guiding component 8 includes a guide wheel 81 around which the electrode wire 4 bypasses. The guide wheel 81 can rotate around its own axis to guide and support the electrode wire 4.

[0042] Specifically, the electrode wire 4 needs to perform a wire feeding movement so that the electrode wire 4 can be wound around the outer wall of the wire storage cylinder 1 and released from the outer wall of the wire storage cylinder 1. The rotatable guide wheel 81 has a guiding effect on the moving electrode wire 4, making the wire feeding movement of the electrode wire 4 smoother.

[0043] Optionally, a guiding groove extending along the circumferential direction is provided on the outer wall of the guide wheel 81. The electrode wire 4 is connected and cooperated with the wall surface of the guiding groove of the guide wheel 81. The guiding groove has a limiting and guiding effect on the electrode wire 4, so that the wire feeding route of the electrode wire 4 can be more accurate and stable.

[0046] In an exemplary embodiment, as Figures 1 to 7 shown, it further includes a fixed conduit 9. The fixed conduit 9 is located on the side of the swing conduit 2 away from the wire storage cylinder 1. One end of the fixed conduit 9 is fixedly connected to the guide wheel seat 82.

[0047] The axes of the fixed conduit 9 and the swing conduit 2 are both tangent to the outer wall of the guide wheel 81. The electrode wire 4 passes through the inner cavity of the fixed conduit 9, then bypasses the outer wall of the guide wheel 81, and then enters the inner cavity of the swing conduit 2.

[0048] Specifically, the fixed conduit 9 has a guiding and leading effect on the wire feeding route of the electrode wire 4. Both the fixed conduit 9 and the swing conduit 2 can be set as rigid conduits.

[0049] As Figure 6 shown, a section of the electrode wire 4 is located between the fixed conduit 9 and the swing conduit 2. This section of the electrode wire 4 is exposed outside the conduit, which is convenient for later cleaning and maintenance operations.
