Abstract
Description
Technical Field
[0001] The utility model belongs to the field of wire mesh weaving, and particularly relates to a multi-axis wire winding machine. Background Art
[0002] In the current technology, coiled wires and straight wires are stored in a wire threading tube for weaving. To achieve the mechanized preparation of wires, Patent 2014203894181 (an eight-axis linkage wire mesh winding machine) provides a wire winding device.
[0003] To improve the operation speed, a method of driving eight rotating shafts by one motor is adopted, and the clutch between the motor output shaft and the rotating shaft is achieved by moving one end of the rotating shaft. It is found in practice that when one end of the rotating shaft moves, there is a situation where the other end of the rotating shaft rotates in the horizontal direction, resulting in slight elastic deformation of the rotating shaft. Therefore, the bearing at the other end of the rotating shaft frequently bears the vertical axial force, and the bearing here frequently receives the lateral force, which is easy to cause damage and may affect the subsequent clutch between the rotating shaft and the motor output shaft and the normal rotation of the rotating shaft.
[0004] In addition, the rotation angle of the rotating shaft directly affects the length of the wound wire, which affects the subsequent wire mesh weaving. Therefore, it is necessary to count the rotation angle of the rotating shaft. Summary of the Utility Model
[0005] To overcome the defects in the above related technologies, the utility model provides a multi-axis wire winding machine, which has the functions of being more stable during clutch operation and counting the rotation angle of the rotating shaft.

At least one compression spring is fixed between the side of the rotating shaft support close to the output gear and the first frame. The adjusting screw is arranged on the side of the first frame away from the output gear, and the end of the adjusting screw abuts against the rotating shaft support. When the adjusting screw rotates, it has the function of pressing the rotating shaft support to move towards the output gear and making the moving gear mesh with the corresponding output gear.

A transmission mechanism is arranged inside the first support frame 11, and the transmission mechanism includes a plurality of output gears 111. An activity frame 121 is arranged inside the second support frame 12, and the activity frame 121 has a tendency to rotate around its vertical axis.

Each wire winding shaft 21 is coaxially and fixedly connected to a corresponding output gear 111. The other end of the wire winding shaft 21 is arranged inside the activity frame 121. When the moving gear 22 meshes with or disengages from the output gear 111, the other end of the wire winding shaft 21 has a tendency to rotate around the vertical axis of the activity frame 121.
[0025] In some examples, as Figure 4 shown, the second support frame 12 can be a square frame, the activity frame 121 is a vertical frame. Both the upper and lower ends of the activity frame 121 are provided with central shafts, and the central shafts are connected to the second support frame 12 through bearings. A plurality of bearings are arranged on the activity frame 121 from top to bottom in sequence. The other end of the wire winding shaft 21 is connected to the activity frame 121 through a bearing.
[0026] Preferably, the inside of the first support frame 11 further includes: a first frame 112, a rotating shaft bracket 113, a compression spring 114, and an adjustment screw 116. Among them, the first frame 112 is of a square frame structure, and the plurality of output gears 111 are arranged inside the first frame 112 from top to bottom in sequence. The rotating shaft bracket 113 is movably arranged inside the first frame 112. A plurality of the moving gears 22 are arranged inside the rotating shaft bracket 113 from top to bottom in sequence, and the moving gears 22 have a tendency to rotate around their center lines relative to the rotating shaft bracket 113. At least one compression spring 114 is fixed between the rotating shaft bracket 113 close to the output gear 111 and the first frame 112. The adjustment screw 116 is arranged on the side of the first frame 112 away from the output gear 111, and the end of the adjustment screw 116 abuts against the rotating shaft bracket 113. When the adjustment screw 116 rotates, it has the effect of pressing the rotating shaft bracket 113 to move towards the output gear 111 and making the moving gear 22 mesh with the corresponding output gear 111.
[0027] Preferably, the transmission mechanism includes: a motor 23 and a moving gear 22. Among them, the motor 23 is fixedly connected to the first frame 112. The moving gear 22 is coaxially and fixedly connected to the output shaft of the motor 23. Two adjacent output gears 111 among the plurality of output gears 111 mesh with each other, and the moving gear 22 meshes with at least one output gear 111 among the plurality of output gears 111.
[0028] In some embodiments, the multi-axis steel wire winding machine further includes a screw press 3 and a wire press guide wheel 5 , the screw press 3 is fixed between the first support frame 11 and the second support frame 12 , and the screw press 3 is parallel to the wire winding shaft 21 .
[0029] like Figure 5 As shown, the wire pressing guide wheel 5 comprises: a sleeve 51, a lower pressure rod 52, an input guide wheel 53 and an output guide wheel 54. The sleeve 51 is movably sleeved on the wire winding shaft 21. The lower pressure rod 52 is fixed on the side wall of the sleeve 51.

The output guide wheel 54 is also fixed on the side wall of the sleeve 51, and the center line of the output guide wheel 54 is parallel to the center line of the sleeve 51. The angle between the connecting line between the output guide wheel 54 and the sleeve 51 and the lower pressure rod 52 is 120°~150°. The input guide wheel 53 is arranged on the side of the lower pressure rod 52 close to the output guide wheel 54.
[0030] When in use, the steel wire is passed through the input guide wheel 53 and wound around the output guide wheel 54 , and then wound from above the output guide wheel 54 onto the side wall of the winding shaft 21 . To improve the relative fixity between the steel wire and the winding shaft 21 , one end of the steel wire may be fixedly connected to the winding shaft 21 .
[0031] By turning the adjusting screw 116, the rotating shaft bracket 113 moves toward the first frame 112 until the output gear 111 can mesh with the moving gear 22. When the wire winding shaft 21 rotates, the wire is naturally wound, and at the same time, the wire drives the sleeve 51 to rotate, so that the lower pressing rod 52 contacts the wire pressing rod 3. At the same time, the sleeve 51 is pushed to run along the wire pressing slide rod 4 when the wire is wound.
[0032] After the wire winding is completed, the adjusting screw 116 is turned, and the compression spring 114 pushes the first frame 112 to move away from the output gear 111, that is, the driving gear 22 is separated from the output gear 111. Then, the above process of winding the wire onto the winding shaft 21 is repeated to perform a new round of wire winding.
