Description

Technical Field

[0001] This application relates to the technical field of motor processing, and in particular to a copper flat wire winding machine and its clamping device. Background Technology

[0002] In the motor manufacturing process, the winding of copper flat wire is a crucial step that must be carried out according to specific structural requirements. Common winding methods include circular spiral winding and waist-shaped spiral winding.

[0003] A significant issue during the winding of copper flat wire is the axial displacement that occurs as winding continues. However, the conveying path of the copper flat wire is generally fixed. This inevitably leads to some deviation during the transfer of the copper flat wire from the unloading station to the winding station.

[0004] To make efficient use of production space, motor manufacturing equipment is often designed to be compact, resulting in a relatively short distance between the unloading station and the winding station. In this case, the axial movement generated during the winding process will exert a lateral force on the copper flat wire at the unloading station, which can cause insertion damage and jamming of the copper flat wire. Utility Model Content

[0005] To alleviate the problems of abrasion and jamming of copper flat wire during the conveying process, this application provides a copper flat wire winding machine and its clamping device.

[0006] In a first aspect, this application provides a clamping device for a copper flat wire winding machine, which adopts the following technical solution: A clamping device for a copper flat wire winding machine includes a worktable, a clamping assembly for guiding and correcting the copper flat wire, a swing sliding assembly for sliding along a direction perpendicular to the copper flat wire conveying direction and swinging up and down in the height direction, and a limiting assembly for limiting the swing amplitude of the clamping assembly. The swing sliding assembly is mounted on the worktable, and the clamping assembly is mounted on the swing sliding assembly.

[0007] In one embodiment: the swing sliding assembly includes two bearing seats mounted on the worktable and two sliding shafts respectively movably mounted on the bearing seats, the two sliding shafts being coaxially arranged and both connected to the clamping assembly.

[0008] In one embodiment, the clamping assembly includes a clamping frame connected to two sliding shafts, and at least two clamping elements for guiding and straightening the copper flat wire, the clamping elements being mounted on the clamping frame.

[0009] In one embodiment: the clamping frame includes a guide plate, a mounting plate and a connecting plate, the connecting plate connects the guide plate and the mounting plate, the guide plate and the mounting plate are arranged parallel to each other, the two sliding shafts are respectively connected to the guide plate and the mounting plate, and the guide plate is provided with a plurality of mounting positions for clamping components.

[0010] In one embodiment: the clamping member includes a plurality of fastening bolts and locking nuts, two protective clamping plates for clamping copper flat wires, and a clamping plate for the fastening bolts to abut against, wherein the fastening bolts pass through the clamping plate, the two protective clamping plates and the guide plate in sequence and are connected to the locking nuts.

[0011] In one embodiment: the guide plate is further provided with a primary correction component, the primary correction component includes two primary correction plates installed on the guide plate, the two primary correction plates are arranged in parallel and spaced apart, and the distance between the two primary correction plates is 1 to 1.1 times the thickness of the copper flat wire.

[0012] In one embodiment: the initial correction plate is a wheel, each wheel is connected to the guide plate through a limiting bearing, and the outer edge of each wheel abuts against the limiting bearing of the other turntable.

[0013] In one embodiment, the limiting component includes a limiting rod mounted on the worktable and a limiting hook mounted on the guide plate, the limiting rod being located within the opening of the limiting hook.

[0014] Secondly, this application provides a copper flat wire winding machine, which adopts the following technical solution: A copper flat wire winding machine includes a winding device and a clamping device. The winding device includes a winding disc, a drive motor for driving the winding disc to rotate, and a winding assembly mounted on the winding disc.

[0015] In one embodiment: the winding assembly includes two adjusting rollers fixedly mounted on the winding reel, a rectangular spring sleeved on the adjusting rollers, an adjusting shim for adjusting the misalignment of the rectangular springs, and an adjusting baffle for adjusting the compression of the rectangular springs. The helical directions of the rectangular springs on the two adjusting rollers are the same, and the adjusting shim is sleeved on the adjusting rollers.

[0016] In summary, this application has the following beneficial effects: 1. For the waist-shaped spiral winding structure, the displacement of the copper flat wire during the winding process is compensated by the swing sliding component. That is, when axial displacement occurs at the winding station, the clamping component will also move axially. When the height of the copper flat wire changes during the winding process, the clamping component can swing to compensate, effectively avoiding scratches and jamming of the copper flat wire on the clamping component. 2. The clamping assembly can guide the copper flat wire. At the same time, through the setting of the clamping parts and the initial straightening assembly, the copper flat wire can be straightened so that it is in a straight state when it is sent to the winding station.

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] A copper flat wire winding machine, such as Figure 1As shown, the device includes a winding device 10 and a clamping device 20. The winding device 10 includes a winding disc 30, a drive motor 40 for driving the winding disc 30 to rotate, and a winding assembly 50 mounted on the winding disc 30.

[0022] This embodiment uses a waist-shaped spiral winding as an example for illustration, referring to... Figure 2 and Figure 3 The winding assembly 50 includes two adjusting rollers 51 fixedly mounted on the winding reel 30, a rectangular spring 52 sleeved on the adjusting rollers 51, an adjusting shim 53 for adjusting the misalignment of the rectangular spring 52, and an adjusting baffle 54 for adjusting the compression of the rectangular spring 52.

[0023] The winding reel 30 is mounted on the shaft of the drive motor 40. Multiple mounting holes are provided on the winding reel 30. The adjusting roller 51 passes through the mounting holes. By mounting it to different mounting holes, the waist length can be adjusted.

[0024] The rectangular springs 52 on the two adjusting rollers 51 have the same helical direction. The rectangular spring 52 refers to a spring with a rectangular cross-section. Adjusting shims 53 are fitted onto the adjusting rollers 51. By adjusting the number of adjusting shims 53 at both ends of the rectangular springs 52, the two rectangular springs 52 are misaligned.

[0025] The end of the adjusting roller 51 passes through the adjusting baffle 54 and is connected to the nut. The compression of the rectangular spring 52 can be adjusted by adjusting the nut.

[0026] During winding, the copper flat wire is guided by two interlaced rectangular springs 52, so that the winding disc 30 automatically forms a spiral winding structure of the copper flat wire during rotation.

[0027] like Figure 4 and Figure 5 As shown, the clamping device 20 includes a worktable 100, a clamping assembly 200 for guiding and correcting the copper flat wire, a swing sliding assembly 300 for the clamping assembly 200 to slide along the direction perpendicular to the copper flat wire conveying direction and swing up and down in the height direction, and a limiting assembly 400 for limiting the swing amplitude of the clamping assembly 200.

[0028] The drive motor 40 is also mounted on the worktable 100. The swing sliding assembly 300 includes two bearing seats 310 mounted on the worktable 100 and two sliding shafts 320 respectively movably mounted on the bearing seats 310. The two sliding shafts 320 are coaxially arranged and are both connected to the clamping assembly 200.

[0029] The clamping assembly 200 includes a clamping frame 210 connected to two sliding shafts 320, at least two clamping elements 220 for guiding and correcting the copper flat wire, and a primary correction assembly 230 for guiding the copper flat wire. The clamping elements 220 are mounted on the clamping frame 210.

[0030] The clamping frame 210 includes a guide plate 211, a mounting plate 212, and a connecting plate 213. The connecting plate 213 connects the guide plate 211 and the mounting plate 212. The guide plate 211 and the mounting plate 212 are arranged in parallel and spaced apart, so that the copper flat wire can pass through the space between the guide plate 211 and the mounting plate 212. Two sliding shafts 320 are respectively connected to the guide plate 211 and the mounting plate 212. The guide plate 211 is provided with multiple mounting positions for the clamping components 220 to be installed.

[0031] In this embodiment, two clamping members 220 are used as an example. Each clamping member 220 includes multiple fastening bolts 221 and locking nuts 222, two protective clamping plates 223 for clamping copper flat wires, and a clamping plate 224 for the fastening bolts 221 to abut against. The fastening bolts 221 pass through the clamping plate 224, the two protective clamping plates 223, and the guide plate 211 in sequence and are connected to the locking nuts 222. In use, the copper flat wire passes between the two protective clamping plates 223, and the distance between the two protective clamping plates 223 can be adjusted by adjusting the locking nuts 222.

[0032] In use, along the conveying direction, the distance between the two protective clamps 223 on the two clamping members 220 is gradually reduced. The distance between the two protective clamps 223 on the first clamping member 220 can be slightly greater than or equal to the thickness of the copper flat wire, while the distance between the two protective clamps 223 on the second clamping member 220 is slightly less than the thickness of the copper flat wire. That is, the first clamping member 220 does not clamp the copper flat wire, while the second clamping member 220 needs to clamp the copper flat wire. This setting makes the copper flat wire straightened on the two clamping members 220.

[0033] In addition, the protective clamping plate 223 is preferably made of smooth plastic material to avoid damage to the surface of the copper flat wire, while the clamping plate 224 is made of metal material to make the stress distribution as uniform as possible after clamping.

[0034] The primary correction assembly 230 is located in front of the two clamping members 220. The copper flat wire passes through the primary correction assembly 230 and then through the two clamping members 220. The primary correction assembly 230 includes two primary correction plates 231 mounted on the guide plate 211. The two primary correction plates 231 are arranged in parallel and spaced apart, and the distance between the two primary correction plates 231 is 1 to 1.1 times the thickness of the copper flat wire.

[0035] The primary correction plate 231 is a wheel, and each wheel is connected to the guide plate 211 through a limit bearing 232. The wheel is fixedly installed on the limit bearing 232. The thickness of the limit bearing 232 is greater than the thickness of the primary correction plate 231, and the outer edge of any wheel abuts against the limit bearing 232 of the other wheel.

[0036] The limiting bearing 232 is fixedly installed on the guide plate 211 by bolts. The guide plate 211 is provided with an adjustment groove into which the limiting bearing 232 can be inserted. The distance between the two primary correction plates 231 can be adjusted by bolts through the setting of the adjustment groove.

[0037] The limiting component 400 includes a limiting rod 410 and a limiting hook 420. The limiting rod 410 is installed on the worktable 100 and located below the guide plate 211. The limiting hook 420 is installed below the guide plate 211, and the limiting rod 410 is located in the opening of the limiting hook 420. The swing amplitude of the guide plate 211 is limited by the contact between the limiting rod 410 and the limiting hook 420.

[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
