The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] like Figure 1-3 The wire mesh filter element 2 of the present invention is a wire feeding tool for winding a wire gap filter element of a CNC lathe, comprising a wire winding tool base 1, a wire feeding end 2, a tightening plug 3, a wire outlet end 5, a pin shaft 6, and a guide wheel 7; the wire feeding end 2 and the wire outlet end 5 are respectively arranged at two ends of the wire winding tool base 1 and are located on the same axis, ensuring that the wire inlet on the wire feeding end 2 and the wire outlet on the wire outlet end 5 are located on the same straight line. The wire inlet and the wire outlet axes coincide with each other to prevent the wire from having a force component during movement, ensuring that the wire is output smoothly. There are two tightening plugs 3, which are symmetrically arranged on the two second supports 11 of the wire winding tool base 1 near the wire feeding end 2, and there are two guide wheels 7, which are symmetrically arranged on one side of the wire winding tool base 1, and a floating adjustment structure is provided on the surface of the wire winding tool base 1 on the side opposite to the two guide wheels 7. The floating adjustment structure is located on the central axis of the two guide wheels 7, and the surface of the wire winding tool base 1 near the wire outlet end 5 is provided with two symmetrical floating adjustment structures.

[0036] The wire inlet end 2 and the wire outlet end 5 are fixed to the wire winding tool base 1 by tightening screws to ensure that the axis of the wire outlet and the wire inlet coincide, preventing the wire from having a force component during movement and ensuring smooth wire output.

[0037] like Figure 3 As shown, a base 8 for connecting to a CNC machine tool is provided at the bottom of the wire winding tool base 1.

[0038] like Figure 4 As shown, a first support 9 is provided at one end of the wire winding tool base 1, and a through hole is provided inside the first support 9. A wire feed end 2 is provided in the through hole of the first support 9 and fixed by screws. A wire inlet is provided inside the wire feed end 2. Two symmetrical second supports 11 are provided on the surface of the wire winding tool base 1 near the first support 1. Tightening plugs 3 are symmetrically mounted on the two second supports 11 by screws. The positions of the two tightening plugs 3 can be adjusted by the screws engaging the threaded holes on the second supports 11. The two tightening plugs 3 are aligned and leveled to play the role of smoothing, flattening and feeding the wire.

[0039] like Figure 1 As shown, one end of the guide wheel 7 is connected to the wire winding tooling base 1 through a thread, and the other end is a rotatable guide wheel body. A wire groove is set on the outer circle of the guide wheel body for the wire to pass through.

[0040] like Figure 4 As shown, the floating adjustment structure arranged on the side opposite to the two guide wheels 7 is installed on the wire winding tool base 1 through the third support 12, and the two floating adjustment structures close to the wire outlet end 5 are installed on the wire winding tool base 1 through the fourth support 14.

[0041] like Figure 1-2 As shown, the floating adjustment structure includes an adjustable screw 4, one end of the adjustable screw 4 cooperates with the threaded hole of the third support 12 or the fourth support 14, and is locked by a nut 15, and the other end is a U-shaped opening structure, and a bearing 16 is installed inside the U-shaped opening structure through a pin 6, and the outer cylindrical surface of the bearing 16 is in contact with the wire; a spring 17 is sleeved on the adjustable screw 4, one end of the spring 17 is in contact with the end face of the third support 12 or the fourth support 14, and the other end is in contact with the end of the U-shaped opening structure, and the spring 17 is in a compressed state. When the locking nut 15 is loosened, the adjustable screw 4 moves toward the wire under the action of the spring 17 force to control the smooth transmission of the wire.

[0042] The bearing 16 of the floating adjustment structure on the third support 12 is connected to the adjustable screw 4 through the pin 6. After the spring 17 is installed on the adjustable screw 4, it is connected and fixed to the wire winding tooling base 1 through the locking nut 15. The force of the spring 17 is used to achieve the "floating" functional requirement, effectively controlling the smooth transmission of the wire.

[0043] The two bearings 16 of the two floating adjustment structures on the fourth support 14 are respectively installed on the adjustable screw 4 through the pin 6. After the spring 17 is installed, it is connected to the wire winding tooling base 1 through the locking nut 15. The spring 17 is used to apply force for pre-adjustment and centering to ensure that it coincides with the axis of the wire outlet and the wire outlet tension is uniform, thereby ensuring that the wire winding pitch is uniform and the operation is simple and stable.

[0044] like Figure 9 As shown, a plane is machined on the outer cylindrical surface of the adjustable screw 4, and the plane cooperates with the end of the limit screw vertically set in the top threaded hole on the third or fourth support 14 to prevent the adjustable screw 4 from rotating.

[0045] like Figure 12-14 As shown, the wire outlet end 5 includes two oppositely arranged semicircular copper sleeve structures, which are in close contact with each other, and semicircular grooves 13 at the same position are arranged on the contact surface, and the two semicircular grooves 13 form a wire outlet hole.

[0046] The following is a detailed introduction to each component:

[0047] 1. Wire winding tooling base 1

[0048] The entire wire winding tooling base has a size of 174×76×68, which is compact. According to the rotating cutter head structure, it is fixed on the tool holder of the CNC lathe using the external cylindrical tool connection method. Figure 4 As shown, the inlet ① of the first support 9 is mounted with the wire feed end 2, the outlet ④ of the fourth support 14 is mounted with the wire outlet end 5, the threaded ends ② of the two second supports 11 are fixed with hexagon socket screws to the top plug 3, the three optical holes ③ of the third support 12 and the two fourth supports 14 are mounted with adjustable screws 4, and the threaded ends ⑤ are mounted with the guide wheel assembly 32*31. The overall structure ensures that the axis of the wire outlet and the wire inlet coincide, and the wire outlet is consistent with the center of the X-axis of the CNC lathe. The layout is reasonable to prevent clamping interference.

[0049] 2. Wire feed end 2

[0050] like Figure 7 As shown, the wire feed end 2 adopts an integrated structure made of SFBN material, and the small hole for threading the wire plays a flexible role in correcting the left and right swing of the wire when it enters, and is fixed to the first support 9 on the wire winding tooling base 1 by a tightening screw.

[0051] 3. Tighten the plug 3

[0052] The two top tightening plugs 3 are made of SFPN or PFI material, and are connected to the second support 11 on the wire winding tool base 1 through the hexagon socket screws and aligned and leveled, which plays the role of wire drawing, flattening and wire feeding. The outer circle is knurled for easy installation. Figure 8 shown.

[0053] 4. Adjustable screw 4

[0054] like Figure 9-11 As shown, the adjustable screw 4 is a "U-shaped" structure, and the bearing 16 is installed at the end of the "U-shaped" structure through the pin 6. After the spring 17 is installed at one end of the screw, it is connected and fixed to the third and fourth supports 14 on the wire winding tooling base 1 through the locking nut 15. After the spring 17 is installed, it is connected and fixed to the wire winding tooling base 1 through the locking nut 15. The force of the spring 17 realizes the "floating" functional requirement. The straight edge of the adjustable screw 4 is tightened with a tightening screw to ensure angular stability when adjusting the floating structure, effectively controlling the smooth transmission of the wire.

[0055] 5. Wire end 5

[0056] like Figure 12-14 The wire outlet end 5 adopts a two-petal copper sleeve structure. The two petals are in close contact and are fixed to the fifth support 18 on the wire winding tooling base 1 by tightening screws to ensure that the wire at the wire outlet end is horizontal and stable with the X-axis, thereby ensuring the quality of the wire winding of the parts.

[0057] Tooling operation steps:

[0058] 01. The on-site technicians will separately deliver the wire winding tooling base 1, wire inlet end 2, tightening plug 3, adjustable screw 4, wire outlet end 5, and pin 6 to the site, and collect the bearing assembly, guide wheel assembly 32*31 and a few tightening screws.

[0059] 02. The on-site technicians respectively install the wire inlet end 2 and the wire outlet end 5 on the first support 9 and the fifth support 18 of the wire winding tooling base 1 through the tightening screws to ensure that the axis of the wire outlet and the wire inlet coincide; connect the two tightening ends 3 to the two second supports 11 on the wire winding tooling base 1 through the hexagon socket screws and align and level them; connect the bearing to the adjustable screw 4 through the pin 6, and after the adjustable screw 4 is installed with the spring 17, it is connected and fixed to the third support 12 on the wire winding tooling base 1 through the locking nut; install the other two bearings 16 on the adjustable screw 4 through the pin 6, and after installing the spring 17, connect them to the fourth support 14 on the wire winding tooling base 1 through the locking nut 15, and use the force of the spring 17 to pre-adjust and center.

[0060] 03. The operator installs the assembled tooling and wire wheel on the tool holder of the CNC lathe, inserts the wire and adjusts the alignment of each structure and smooth transmission.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should all be included in the protection scope of the present invention.
