Description

Technical Field

[0001] This utility model relates to the field of transformer winding, and more particularly to a spindle device and a winding bushing machine. Background Technology

[0002] A wire winding sleeve machine is a device that sleeves copper wire and winds copper wire and insulating tape onto a frame.

[0003] During the winding process, crossover is required. Crossover refers to winding one end of the copper wire on the circumference of the bobbin to the pin of the bobbin. However, the pin and the copper wire that need to be crossed are not on a vertical straight line on the same horizontal plane. In traditional winding operations, customers do not have requirements in this regard, so the copper wire involved in the crossover is relatively inclined on the bobbin. However, at this stage, we have received requirements from customers that the copper wire involved in the crossover part should not be inclined relative to the bobbin, but should be vertical. The current equipment lacks the ability to adjust the wire, which makes it impossible to align the copper wire. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a spindle device and a winding sleeve machine, aiming to solve the problem of the inability to adjust the tilt of the copper wire.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a spindle device, comprising a spindle mechanism, characterized in that it further comprises a wire pressing mechanism, the spindle mechanism comprising a spindle seat, the wire pressing mechanism being disposed on the spindle seat, the wire pressing mechanism comprising a wire pressing fixture and a linear movement mechanism that enables the wire pressing fixture to have multi-dimensional changes, the wire pressing fixture having a bottom that abuts against the copper wire, and at least two mutually perpendicular guide sides.

[0006] The beneficial effects of this utility model are:

[0007] This utility model features a novel design for the spindle mechanism, specifically designed for use on the spindle mechanism. The output end of the wire pressing mechanism, also known as the wire pressing fixture, is designed based on the linear movement mechanism that serves as the drive source on the spindle mechanism and the copper wire. The calibration and alignment of the copper wire is achieved by pressing the wire end of the ribbon cable with the bottom of the wire pressing fixture, and then pulling the part of the copper wire used to wrap around the pin, forcing the part of the copper wire corresponding to the cross-wire to be attached to several guide sides, thereby obtaining a vertical cross-wire part.

[0008] Furthermore, the bottom surface is composed of two clamping platforms with a height difference. The copper wire needs to be fully wound on the winding section. The winding section should not only have many turns of copper wire, but also many layers of overlapping copper wire. For example, it takes ten turns of copper wire to fully wind one layer. After the tenth turn, the eleventh turn is wound on top of the first turn of copper wire. At the same time, the eleventh turn is the starting point for the second layer of winding. Alternatively, if the customer requires only two layers of copper wire, then after the fifteenth turn of copper wire in the second layer is wound, the first clamping platform and the second clamping platform abut against the surfaces of the first and second layers, respectively. Moreover, the first clamping platform abuts against the outer periphery of the fifteenth turn of copper wire. It is not difficult to see that the first clamping platform and the second clamping platform are both used to constrain the entire second layer for future cross-line alignment.

[0009] It should be noted that the two ends of the copper wire are in two separate devices: one end is in the wire spool, and the other end is in the guide needle mechanism. Therefore, only the portion of the copper wire other than the two ends is wound around the winding part of the bobbin. Thus, when the guide needle mechanism drags the cross-wire portion after the eleventh turn, the second layer of copper wire is compacted and will not arch or come off the coil. The cross-wire portion dragged by the guide needle mechanism can only move along and against the guide side. After the copper wire is dragged on two mutually perpendicular guide sides, the cross-wire portion on the bobbin is in the shape of a "┐" (viewed from above).

[0010] The linear motion mechanism is existing technology, and its structure will not be described in detail.

[0011] The output end of a traditional spindle mechanism is a rotating rod, which is directly inserted into the frame to drive the frame to rotate. The rotating rod has ball bearings embedded in it, and the spring inside the rotating rod constantly pushes against the ball bearings, so that the surface of the ball bearings protrudes outside the rotating rod. After the frame jumps over the ball bearings, the frame is locked to the rotating rod by the ball bearings. However, this locking method is not secure. If the rotation speed is too high, the frame may be thrown off the rotating rod.

[0012] Currently, a positioning fixture is provided to replace the rotating rod. This positioning fixture includes a body and a lever. The body has a mounting groove, and the lever is embedded in the mounting groove and assembled into the mounting groove via a rotating shaft. The end of the lever corresponding to the pressing platform is the first end, and the end opposite to the first end is the second end. The first end has a groove. When the first end is raised, the groove actively cooperates with the frame to position the frame. The body is also fitted with an unlocking sleeve. The unlocking sleeve slides on the body and has two states: covering the second end and not covering the second end. When covering the second end, the second end is sunk into the mounting groove, and the corresponding first end is naturally raised. When the unlocking sleeve is misaligned with the second end, in its natural state, the first end is sunk into the mounting groove, and the second end is raised.

[0013] The positioning fixture also includes an adjusting nut and a spring. The adjusting nut is threaded to the main body. The unlocking sleeve has an annular groove inside that matches the outer circumference of the adjusting nut. The unlocking sleeve is fitted onto the adjusting nut through the annular groove. The spring is set in the annular groove. The adjusting nut prevents the spring from disengaging from the annular groove. Under the action of the spring, a force is continuously applied that pushes the unlocking sleeve toward the skeleton. In other words, unlocking is achieved passively by the spring, reducing the secondary use of the drive source and reducing energy consumption. At the same time, the spring's response is relatively timely.

[0014] It also includes a pin, and the unlocking sleeve has a limiting groove. The pin is set on the main body and located in the limiting groove. The distribution at both ends of the limiting groove corresponds to the sliding direction of the unlocking sleeve.

[0015] The aforementioned driving source consists of an existing linear moving mechanism, an unlocking plate, and a mounting block. The unlocking plate has a groove that adapts to the shape of the outer ring surface of the unlocking sleeve. At the same time, an extension is provided on the outer ring surface of the unlocking sleeve. The unlocking plate is set on the output end of the linear moving mechanism through the mounting block, and the unlocking plate and the extension are corresponding. By pushing the extension, the entire unlocking sleeve slides. This provides a mechanical pushing method to realize the movement of the release sleeve. Attached Figure Description

[0027] A winding sleeve machine includes a spindle assembly, which includes a spindle mechanism 1. The machine is characterized by further including a wire pressing mechanism 2. The spindle mechanism 1 includes a spindle seat 100. The wire pressing mechanism 2 is disposed on the spindle seat 100. The wire pressing mechanism 2 includes a wire pressing fixture 200 and a linear movement mechanism that allows the wire pressing fixture 200 to have multi-dimensional changes. The wire pressing fixture 200 has a bottom that abuts against a copper wire 3, and at least two mutually perpendicular guide sides 201.

[0028] The beneficial effects of this utility model are:

[0029] This utility model features a novel design on the spindle mechanism 1, specifically designed for use on the spindle mechanism 1. The output end of the wire pressing mechanism 2, namely the wire pressing fixture 200, is designed based on the linear moving mechanism on the spindle mechanism 1 that serves as the drive source, and the copper wire 3. The calibration and alignment of the copper wire 3 is achieved by pressing the end of the cable with the bottom of the wire pressing fixture 200, and then pulling the part of the copper wire 3 used to wrap around the pin, forcing the part of the copper wire 3 corresponding to the crossover point to be attached to several guide sides 201, thereby obtaining a vertical crossover point 300.

[0030] Furthermore, the bottom surface is composed of two clamping platforms with a height difference. The copper wire 3 needs to be fully wound on the winding part. The winding part should not only have many turns of copper wire 3, but also many layers of overlapping copper wire 3. For example, it takes ten turns of copper wire 3 to fully wind one layer. After the tenth turn, the eleventh turn is wound above the first turn of copper wire 3. At the same time, the eleventh turn is the starting point for the second layer of winding. For example, if the customer requires only two layers of copper wire 3, then after the fifteenth turn of copper wire 3 in the second layer is wound, the first clamping platform 202 and the second clamping platform 203 respectively abut against the surfaces of the first layer and the second layer. Moreover, the first clamping platform 202 also abuts against the outer periphery of the fifteenth turn of copper wire 3. It is not difficult to see that the first clamping platform 202 and the second clamping platform 203 are both used to constrain the entire second layer for future cross-line alignment.

[0031] It should be noted that the two ends of the copper wire 3 are located in two separate devices: one end is in the wire coil, and the other end is in the guide needle mechanism 4. Therefore, only the portion of the copper wire 3, excluding the two ends, is wound around the winding section of the bobbin 5. Consequently, when the guide needle mechanism 4 moves the cross section 300 after eleven turns, the second layer of copper wire 3, being compacted, will not arch or come off the coil. The cross section 300 dragged by the guide needle mechanism 4 can only move along and against the guide side 201. After the copper wire 3 is dragged on two mutually perpendicular guide sides 201, the cross section 300 forms a "┐" shape on the bobbin 5. Figure 8 (View from above)

[0032] The linear motion mechanism is existing technology, and its structure will not be described in detail.

[0033] The output end of the traditional spindle mechanism is a rotating rod, which is directly inserted into the frame 5 to drive the frame 5 to rotate. The rotating rod has ball bearings embedded in it, and the spring inside the rotating rod constantly pushes against the ball bearings, so that the surface of the ball bearings protrudes outside the rotating rod. After the frame 5 jumps over the ball bearings, the ball bearings lock the frame 5 onto the rotating rod. However, this locking method is not secure. If the rotation speed is too high, the frame 5 may be thrown off the rotating rod.

[0034] Currently, a positioning fixture is provided to replace the rotating rod. This positioning fixture includes a body 61 and a lever 62. The body 61 has a mounting groove, and the lever 62 is embedded in the mounting groove and assembled into the mounting groove through a rotating shaft. The end of the lever 62 corresponding to the pressing platform is the first end, and the end of the lever 62 opposite to the first end is the second end. The first end has a groove 62-a. When the first end is raised, the groove 62-a actively cooperates with the frame 5 to position the frame 5 (specifically, the frame 5 is embedded in the groove 62-a). The body 61 is also fitted with an unlocking sleeve 63. The unlocking sleeve 63 is fitted on the body 61. When the unlocking sleeve 63 slides on the body 61, it has two states: covering the second end and not covering the second end. When covering the second end, the second end is sunk into the mounting groove, and the corresponding first end is naturally raised. When the unlocking sleeve 63 is misaligned with the second end, in its natural state, the first end is sunk into the mounting groove, and the second end is raised.

[0035] The positioning fixture also includes an adjusting nut 64 and a spring 65. The adjusting nut 64 is threadedly connected to the body 61. The unlocking sleeve 63 has an annular groove 63-a that matches the outer circumference of the adjusting nut 64. The unlocking sleeve 63 is fitted onto the adjusting nut 64 through the annular groove 63-a. The spring 65 is set in the annular groove 63-a. The adjusting nut 64 prevents the spring 65 from disengaging from the annular groove 63-a. Under the action of the spring 65, a force is continuously applied to push the unlocking sleeve 63 towards the skeleton 5. In other words, unlocking is passively achieved by the spring 65, reducing the secondary use of the drive source and reducing energy consumption. In addition, the response of the spring 65 is relatively timely.

[0036] It also includes a pin 64, and the unlocking sleeve 63 is provided with a limiting groove 65. The pin 64 is set on the body 61 and located in the limiting groove 65. The distribution of the two ends of the limiting groove 65 corresponds to the sliding direction of the unlocking sleeve 63. The use of the limiting groove 65 is to give the unlocking sleeve 65 the maximum travel position, and also to ensure that the unlocking sleeve 63 slides off the body 61.

[0037] The aforementioned driving source consists of an existing linear moving mechanism, an unlocking piece 71, and a mounting block 72. The unlocking piece 71 has a groove 71-a that adapts to the shape of the outer ring surface of the unlocking sleeve 63. At the same time, an extension 63-b is also provided on the outer ring surface of the unlocking sleeve 63. The unlocking piece 71 is set on the output end of the linear moving mechanism through the mounting block 72. By pushing the extension 63-b, the entire unlocking sleeve 63 slides. This provides a mechanical pushing method to realize the movement of the unlocking sleeve 63.
