Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of transformer manufacturing, and particularly relates to a wire clamping device and a coil winding device. Background Art
[0002] The coil is the core part of the transformer operation, and its operation reliability and safety are particularly important.
[0003] During the coil winding process, the winding tightness will also affect the impedance characteristics of the transformer. The impedance is the sum of the resistance and inductive reactance presented by the transformer under the action of an alternating voltage, which directly affects the load capacity and efficiency of the transformer.
[0004] Secondly, the tightness of the coil also directly affects the mechanical strength of the coil. Different electrodynamic forces will be generated at different positions of the coil during operation. Only when the coil is wound tightly enough can the stable operation of the coil be ensured.
[0005] Therefore, in a production environment where the wire reel placement rack cannot provide stable and effective pulling force, in the prior art, an electromagnetic wire tensioning device is usually added before the electromagnetic wire enters the winding die to ensure the coil winding quality. A large force caliper is used on-site to clamp the upper cover plate, but such an operation is likely to cause excessive clamping force, resulting in the locking of the tensioning device and the wire. Summary of the Utility Model
[0006] The technical problem to be solved by the utility model is to provide a wire clamping device and a coil winding device in view of the above deficiencies existing in the prior art. By using the wire clamping device, the clamping force on the wire can be flexibly adjusted, making the adjustment of the clamping force smoother and avoiding the situation of locking of the workpiece to be clamped.
[0007] In a first aspect, an embodiment of the present utility model provides a wire clamping device, which includes a body, a clamping member, and a pressure adjustment assembly. The body includes a U-shaped seat and a top plate. The U-shaped seat and the top plate enclose a lead channel with two open ends, and the lead channel is used to accommodate the clamping member. First through holes are provided in the top plate corresponding to the positions of the two side plates of the U-shaped seat. The clamping member is arranged in the lead channel. The clamping member has a clamping channel with two open ends, and the clamping channel communicates with the lead channel. The clamping member is connected to the top plate, and the clamping member can support the top plate so that there is a gap between the top plate and the two side plates of the U-shaped seat in the vertical direction. The clamping member is used to clamp a workpiece to be clamped passing through the clamping channel, and can adjust the clamping force on the workpiece to be clamped under the action of an external force. The pressure adjustment assembly includes a first bolt and a compression spring. The first bolt is correspondingly arranged with the first through hole, and after passing through the first through hole, the first bolt is threadedly connected to the side plate of the U-shaped seat. The compression spring is sleeved outside the first bolt, one end of the compression spring abuts against the head of the first bolt, and the other end abuts against the upper surface of the top plate. When the first bolt is rotated, by adjusting the compression amount and elastic force of the compression spring, the pressure applied by the compression spring on the top plate and the pressure applied by the top plate on the clamping member are adjusted, and then the clamping force on the workpiece to be clamped is adjusted through the clamping member.
[0008] In some embodiments, the clamping member includes a first clamping plate and a second clamping plate. In the vertical direction, the first clamping plate and the second clamping plate are opposite and spaced apart. The first clamping plate is connected to the top plate and is used to clamp the upper surface of the workpiece to be clamped. The second clamping plate is connected to the bottom plate of the U-shaped seat and is used to clamp the lower surface of the workpiece to be clamped. At least one of the first clamping plate and the second clamping plate can slide relative to the body in the vertical direction to adjust the size of the clamping channel in the vertical direction.
[0009] In some embodiments, the wire clamping device further includes a first driving assembly. The first driving assembly is configured to drive the first clamping plate to slide in the vertical direction, and the first clamping plate is connected to the top plate through the first driving assembly. The first driving assembly is configured to drive the second clamping plate to slide in the vertical direction, and the second clamping plate is connected to the bottom plate of the U-shaped seat through the first driving assembly.
[0010] In some embodiments, the clamping member further includes a third clamping plate and a fourth clamping plate. In a first direction, the third clamping plate and the fourth clamping plate are opposite and spaced apart, and the first clamping plate, the second clamping plate, the third clamping plate, and the fourth clamping plate together define the clamping channel; wherein the first direction is a direction perpendicular to the extending direction of the clamping channel in a horizontal plane. The third clamping plate and the fourth clamping plate are respectively connected to two side plates of the U-shaped seat for clamping two sides of the workpiece to be clamped. At least one of the third clamping plate and the fourth clamping plate is capable of sliding relative to the body in the first direction to adjust the size of the clamping channel in the first direction.
[0011] In some embodiments, the wire clamping device further includes a second driving assembly. The second driving assembly is configured to drive the third clamping plate to slide in the first direction, and the third clamping plate is connected to a side plate of the U-shaped seat through the second driving assembly. The second driving assembly is configured to drive the fourth clamping plate to slide in the first direction, and the fourth clamping plate is connected to the other side plate of the U-shaped seat through the second driving assembly.
[0012] In some embodiments, first comb-like structures are formed on both sides of the first clamping plate that are opposite and spaced apart in the first direction, second comb-like structures are formed on both sides of the second clamping plate that are opposite and spaced apart in the first direction, third comb-like structures are formed on both sides of the third clamping plate that are opposite and spaced apart in the vertical direction, and fourth comb-like structures are formed on both sides of the fourth clamping plate that are opposite and spaced apart in the vertical direction. The first comb-like structures on both sides of the first clamping plate are in clearance fit with the third comb-like structures on one side of the third clamping plate and the fourth comb-like structures on one side of the fourth clamping plate respectively, and the second comb-like structures on both sides of the second clamping plate are in clearance fit with the third comb-like structures on the other side of the third clamping plate and the fourth comb-like structures on the other side of the fourth clamping plate respectively.
[0013] In some embodiments, the third clamping plate and the fourth clamping plate have the same shape. In the direction from the inlet of the clamping channel to the outlet of the clamping channel, the heights of the third comb-like structure of the third clamping plate and the fourth comb-like structure of the fourth clamping plate gradually decrease, and the first clamping plate and the second clamping plate gradually approach each other so that the height of the clamping channel gradually decreases.
[0014] In some embodiments, an elastic material layer is provided on the surface of at least one of the first clamping plate, the second clamping plate, the third clamping plate, and the fourth clamping plate facing the clamping channel. Chamfered edges are provided at the edges of the first clamping plate, the second clamping plate, the third clamping plate, and the fourth clamping plate.
[0015] In some embodiments, the wire clamping device further includes a first wire combing frame and a second wire combing frame. The first wire combing frame is fixed at the inlet of the lead channel, and the second wire combing frame is fixed at the outlet of the lead channel for supporting and combing the workpiece to be clamped.
[0016] In some embodiments, the wire clamping device further includes a telescopic support rod and a fixing ring. The telescopic support rod has a base at the bottom, and the top end of the telescopic support rod is fixedly connected to the bottom plate of the U-shaped seat. The fixing ring is fixed on the telescopic support rod, and an external strap passes through the fixing ring and is fixed on the fixing ring to fix the telescopic support rod through the strap.
[0017] Thus, in the wire clamping device provided by the embodiment of the present invention, by forming a lead channel with two open ends by the U-shaped seat and the top plate, and arranging a clamping member in the lead channel, the workpiece to be clamped can pass through the clamping channel of the clamping member, and the clamping member can clamp the workpiece to be clamped. By connecting the clamping member to the top plate and enabling the clamping member to support the top plate, a gap can be formed between the top plate and the two side plates of the U-shaped seat in the vertical direction, so there is no mutual force between the U-shaped seat and the top plate; after setting the first bolt and the compression spring, by passing the first bolt through the first through hole of the top plate and threadedly connecting it to the side plate of the U-shaped seat, one end of the compression spring abuts against the head of the first bolt, and the other end abuts against the upper surface of the top plate, the elastic force exerted by the compression spring on the top plate can be transmitted to the clamping member through the top plate; at the same time, due to the supporting effect of the clamping member on the top plate, the relative position between the top plate and the U-shaped seat remains fixed. Therefore, when the first bolt is rotated, the distance between the head of the first bolt and the top plate will change, so that the compression amount and elastic force of the compression spring will change, the pressure of the compression spring on the top plate will change, and the pressure exerted by the top plate on the clamping member will change, thereby adjusting the external force applied to the clamping member, and the clamping member can adjust the clamping force on the workpiece to be clamped under the action of the external force. That is, by rotating the first bolt, the elastic force of the compression spring can change smoothly to flexibly adjust the clamping force of the clamping member on the workpiece to be clamped, making the adjustment of the clamping force smoother and avoiding the situation of locking the workpiece to be clamped due to excessive clamping force.
[0018] In a second aspect, the embodiment of the present invention further provides a coil winding device, which includes a wire reel, the wire clamping device in the first aspect, and a winding device. The wire clamping device is used to clamp the wire in the wire reel. The winding device is used to wind the wire. The wire in the wire reel passes through the clamping channel of the clamping member in the wire clamping device and then enters the winding device for winding.
[0019] The coil winding equipment provided by the embodiment of the present utility model has the same beneficial effects as the above-mentioned wire clamping device, which will not be elaborated herein. Description of the Drawings

[0032] To enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the drawings and embodiments.
[0033] Embodiment 1:
[0034] As Figure 1 、 Figure 2 and Figure 3 shown, an embodiment of the present utility model provides a wire clamping device, which is applied to the winding process of a transformer winding.
[0035] As Figure 4 shown, the wire clamping device includes a body, a clamping member 5 and a pressure adjustment assembly. The body includes a U-shaped seat 1 and a top plate 2. The U-shaped seat 1 and the top plate 2 enclose a lead channel 1A with two open ends, and the lead channel 1A is used to accommodate the clamping member 5. First through holes are provided on the top plate 2 corresponding to the positions of the two side plates of the U-shaped seat 1. The clamping member 5 is arranged in the lead channel 1A. The clamping member 5 is arranged in the lead channel 1A; the clamping member 5 has a clamping channel 5A with two open ends, and the clamping channel 5A communicates with the lead channel 1A. The clamping member 5 is connected to the top plate 2, and the clamping member 5 can support the top plate 2 so that there is a gap between the top plate 2 and the two side plates of the U-shaped seat 1 in the vertical direction; the clamping member 5 is used to clamp the workpiece to be clamped 6 passing through the clamping channel 5A, and can adjust the clamping force on the workpiece to be clamped 6 under the action of an external force.
[0036] The body is used to support and fix the internal clamping member 5.
[0037] Exemplarily, the U-shaped seat 1 is formed by welding Q235 steel plates.
[0038] After the clamping channel 5A communicates with the lead channel 1A, the workpiece to be clamped 6 can enter and exit the clamping channel 5A of the clamping member 5 through the openings at both ends of the lead channel 1A.
[0039] Exemplarily, the workpiece to be clamped 6 can be a single wire or multiple wires.
[0040] Combined with Figure 1 、 Figure 4 and Figure 5 , the pressure adjustment assembly includes a first bolt 3 and a compression spring 4. The first bolt 3 is correspondingly arranged with the first through hole. After the first bolt 3 passes through the first through hole, it is threadedly connected to the side plate of the U-shaped seat 1. The compression spring 4 is sleeved on the outside of the first bolt 3. One end of the compression spring 4 abuts against the head of the first bolt 3, and the other end abuts against the upper surface of the top plate 2. When the first bolt 3 is rotated, by adjusting the compression amount and elastic force of the compression spring 4, the pressure applied by the compression spring 4 on the top plate 2 and the pressure applied by the top plate 2 on the clamping member 5 are adjusted, and then the clamping force applied to the workpiece to be clamped 6 is adjusted through the clamping member 5.
[0041] Exemplarily, the number of the first through holes at the positions of the top plate 2 corresponding to each side plate of the U-shaped seat 1 can be one or more. The number of the first bolts 3 is the same as that of the first through holes. Threaded holes (such as ordinary coarse-thread M12 threaded holes) adapted to the first bolts 3 are provided at the positions of each side plate of the U-shaped seat 1 corresponding to the first through holes. After the first bolts 3 extend into the threaded holes, they are threadedly connected to the side plates of the U-shaped seat 1.
[0042] As Figure 4 shown, in the vertical direction, there is a gap between the top plate 2 and the two side plates of the U-shaped seat 1. Therefore, there is no interaction force between the U-shaped seat 1 and the top plate 2, and the elastic force exerted on the top plate 2 by the compression spring 4 can be transmitted to the clamping member 5 through the top plate 2.
[0043] It can be understood that, as Figure 4 shown, due to the supporting effect of the clamping member 5 on the top plate 2, the relative positions of the top plate 2 and the U-shaped seat 1 are kept fixed. Therefore, when the first bolt 3 is rotated, the distance between the head of the first bolt 3 and the top plate 2 will change, so that the compression amount and elastic force of the compression spring 4 can be changed, the pressure of the compression spring 4 on the top plate 2 can be changed, and the pressure exerted by the top plate 2 on the clamping member 5 can be changed, thus adjusting the external force exerted on the clamping member 5, and enabling the clamping member 5 to adjust the clamping force on the workpiece to be clamped 6 under the action of this external force, realizing the adjustment of the clamping force on the workpiece to be clamped 6.
[0044] Moreover, by rotating the first bolt 3, the elastic force of the compression spring 4 can be changed smoothly. Therefore, the clamping force of the clamping member 5 on the workpiece to be clamped 6 can be adjusted flexibly, making the adjustment of the clamping force smoother and avoiding the situation of the workpiece to be clamped 6 being locked.
[0045] Therefore, the wire clamping device provided by the embodiment of the present utility model forms a lead channel 1A with two open ends by the U-shaped seat 1 and the top plate 2, and a clamping member 5 is arranged in the lead channel 1A, so that the member to be clamped 6 can pass through the clamping channel 5A of the clamping member 5, and the member to be clamped 6 is clamped by the clamping member 5. By connecting the clamping member 5 to the top plate 2 and enabling the clamping member 5 to support the top plate 2, a gap can be formed between the top plate 2 and the two side plates of the U-shaped seat 1 in the vertical direction. Therefore, there is no mutual force between the U-shaped seat 1 and the top plate 2; after the first bolt 3 and the compression spring 4 are arranged, by passing the first bolt 3 through the first through hole of the top plate 2 and then threadedly connecting it to the side plate of the U-shaped seat 1, one end of the compression spring 4 abuts against the head of the first bolt 3, and the other end abuts against the upper surface of the top plate 2, the elastic force applied by the compression spring 4 on the top plate 2 can be transmitted to the clamping member 5 through the top plate 2; at the same time, due to the supporting effect of the clamping member 5 on the top plate 2, the relative positions of the top plate 2 and the U-shaped seat 1 are kept fixed. Therefore, when the first bolt 3 is rotated, the distance between the head of the first bolt 3 and the top plate 2 will change, so that the compression amount and elastic force of the compression spring 4 will change, the pressure of the compression spring 4 on the top plate 2 will change, the pressure applied by the top plate 2 on the clamping member 5 will change, and thus the external force applied to the clamping member 5 is adjusted. And the clamping member 5 can adjust the clamping force on the member to be clamped 6 under the action of the external force. Therefore, the clamping member 5 can adjust the clamping force on the member to be clamped 6 under the action of this external force. That is, by rotating the first bolt 3, the elastic force of the compression spring 4 can change smoothly, so as to flexibly adjust the clamping force of the clamping member 5 on the member to be clamped 6, make the clamping force smoother during adjustment, and avoid the situation that the member to be clamped 6 is locked due to excessive clamping force.
[0046] In some examples, such as Figure 6A and 6B shown, the material of the compression spring 4 is 65Mn steel, the wire diameter d = 1.6 mm, the spring index C = 8. After calculation, the mean coil diameter D = 12.8 mm, the effective number of turns n = 6, the two ends of the spring are ground flat, the total number of turns of the spring n1 = n + 2.5, the pitch of the spring P = 3 mm, the total height of the spring H0 = P×n + d = 21.2 mm, the inner diameter of the spring D1 = 11.2 mm. After calculation, when the member to be clamped 6 is eight horizontally arranged side-by-side wires, the clamping member 5 can provide a pressing force of 50 N for each wire. At the same time, by rotating the first bolt 3, a certain range of change in the pressing force can be provided on the basis of the pressing force of 50 N.
[0047] In some embodiments, such as Figure 4As shown, the clamping member 5 includes a first clamping plate 7 and a second clamping plate 8. In the vertical direction, the first clamping plate 7 and the second clamping plate 8 are opposite and spaced apart. The first clamping plate 7 is connected to the top plate 2 and is used to clamp the upper surface of the workpiece 6 to be clamped; the second clamping plate 8 is connected to the bottom plate of the U-shaped seat 1 and is used to clamp the lower surface of the workpiece 6 to be clamped. At least one of the first clamping plate 7 and the second clamping plate 8 can slide relative to the machine body in the vertical direction to adjust the size of the clamping channel 5A in the vertical direction.
[0048] The first clamping plate 7 is connected to the top plate 2. Therefore, the first clamping plate 7 can support the top plate 2, and the pressure applied by the compression spring 4 on the top plate 2 can be transmitted to the first clamping plate 7 and converted into a clamping force on the workpiece 6 to be clamped through the first clamping plate 7.
[0049] Exemplarily, when the height of the workpiece 6 to be clamped is relatively large, at least one of the first clamping plate 7 and the second clamping plate 8 can be moved in a direction away from each other so that the distance between the first clamping plate 7 and the second clamping plate 8 can accommodate the workpiece 6 to be clamped; when the height of the workpiece 6 to be clamped is relatively small, at least one of the first clamping plate 7 and the second clamping plate 8 can be moved in a direction closer to each other so that the distance between the first clamping plate 7 and the second clamping plate 8 becomes smaller to clamp the workpiece 6 to be clamped.
[0050] Through the above settings, the distance between the first clamping plate 7 and the second clamping plate 8 can be flexibly adjusted according to the height of the workpiece 6 to be clamped to clamp workpieces 6 to be clamped with different heights.
[0051] In some embodiments, as Figures 1-4 shown, the wire clamping device further includes a first driving assembly 9. The first driving assembly 9 is configured to drive the first clamping plate 7 to slide in the vertical direction, and the first clamping plate 7 is connected to the top plate 2 through the first driving assembly 9.
[0052] Exemplarily, as Figure 4 shown, the first driving assembly 9 is fixed on the top plate 2. One end of the first driving assembly 9 extends into the lead channel 1A and is connected to the first clamping plate 7. By adjusting the size of the first driving assembly 9 located in the lead channel 1A, the first clamping plate 7 can be driven to slide in the vertical direction.
[0053] Exemplarily, the first driving assembly 9 is an adjusting screw. A threaded hole is provided on the top plate 2, and the adjusting screw extends into the threaded hole on the top plate 2. By rotating the adjusting screw, the size of the adjusting screw extending into the lead channel 1A can be adjusted to drive the first clamping plate 7 to slide in the vertical direction.
[0054] Exemplarily, the material of the adjusting screw is Q235-B steel.
[0055] In other examples, as Figure 4As shown, the first driving component 9 is configured to drive the second clamping plate 8 to slide in the vertical direction, and the second clamping plate 8 is connected to the bottom plate of the U-shaped seat 1 through the first driving component 9.
[0056] Exemplarily, as Figure 4 shown, the first driving component 9 is fixed on the bottom plate of the U-shaped seat 1. One end of the first driving component 9 extends into the lead channel 1A and is connected to the second clamping plate 8. By adjusting the size of the first driving component 9 located in the lead channel 1A, the second clamping plate 8 can be driven to slide in the vertical direction.
[0057] Exemplarily, the first driving component 9 is an adjusting screw. A threaded hole is provided on the bottom plate of the U-shaped seat 1. The adjusting screw extends into the threaded hole on the bottom plate of the U-shaped seat 1. By rotating the adjusting screw, the size of the adjusting screw extending into the lead channel 1A can be adjusted to drive the second clamping plate 8 to slide in the vertical direction.
[0058] Through the above settings, the distance between the first clamping plate 7 and the second clamping plate 8 can be flexibly adjusted through the first driving component 9 to clamp workpieces 6 of different heights.
[0059] In some embodiments, as Figure 4 shown, the clamping member 5 further includes a third clamping plate 10 and a fourth clamping plate 11. In the first direction X, the third clamping plate 10 and the fourth clamping plate 11 are opposite and spaced apart, and the first clamping plate 7, the second clamping plate 8, the third clamping plate 10, and the fourth clamping plate 11 jointly enclose a clamping channel 5A. Wherein, the first direction X is a direction perpendicular to the extending direction of the clamping channel 5A in the horizontal plane. The third clamping plate 10 and the fourth clamping plate 11 are respectively connected to the two side plates of the U-shaped seat 1 for clamping two sides of the workpiece 6. At least one of the third clamping plate 10 and the fourth clamping plate 11 can slide relative to the machine body in the first direction X to adjust the size of the clamping channel 5A in the first direction X.
[0060] Figure 3 is a top view of the wire clamping device. The workpiece 6 ( Figure 3 not shown) passes through the wire clamping device in a direction perpendicular to the first direction X. Here, the moving direction of the workpiece 6 passing through the wire clamping device is defined as the second direction Y. The first direction X and the second direction Y are two mutually perpendicular directions in the same horizontal plane.
[0061] Exemplarily, in combination with Figure 4, when the size (width) of the workpiece 6 to be clamped in the first direction X is relatively large, at least one of the third clamping plate 10 and the fourth clamping plate 11 can be moved in a direction away from each other so that the distance between the third clamping plate 10 and the fourth clamping plate 11 can accommodate the workpiece 6 to be clamped; when the size (width) of the workpiece 6 to be clamped in the first direction X is relatively small, at least one of the third clamping plate 10 and the fourth clamping plate 11 can be moved in a direction closer to each other so that the distance between the third clamping plate 10 and the fourth clamping plate 11 becomes smaller to clamp the workpiece 6 to be clamped.
[0062] Through the above settings, the distance between the third clamping plate 10 and the fourth clamping plate 11 can be flexibly adjusted according to the size (width) of the workpiece 6 to be clamped in the first direction X, so as to adapt to workpieces 6 of different sizes in the first direction X, and cooperate with the first clamping plate 7 and the second clamping plate 8 to clamp workpieces 6 of different sizes.
[0063] In some embodiments, as Figure 4 shown, the wire clamping device further includes a second driving assembly 12. The second driving assembly 12 is configured to drive the third clamping plate 10 to slide along the first direction X, and the third clamping plate 10 is connected to a side plate of the U-shaped seat 1 through the second driving assembly 12.
[0064] Exemplarily, as Figure 4 shown, the second driving assembly 12 is fixed on a side plate of the U-shaped seat 1 close to the third clamping plate 10, and one end of the second driving assembly 12 extends into the lead channel 1A to be connected to the third clamping plate 10. By adjusting the size of the second driving assembly 12 located in the lead channel 1A, the third clamping plate 10 can be driven to slide along the first direction X.
[0065] Exemplarily, the second driving assembly 12 is an adjusting screw. A threaded hole is provided on a side plate of the U-shaped seat 1 close to the third clamping plate 10.

By rotating the adjusting screw, the size of the adjusting screw extending into the lead channel 1A can be adjusted to drive the third clamping plate 10 to slide along the first direction X.
[0066] In some other examples, the second driving assembly 12 is configured to drive the fourth clamping plate 11 to slide along the first direction X, and the fourth clamping plate 11 is connected to the other side plate of the U-shaped seat 1 through the second driving assembly 12.
[0067] Exemplarily, the second driving assembly 12 is fixed on a side plate of the U-shaped seat 1 close to the fourth clamping plate 11, and one end of the second driving assembly 12 extends into the lead channel 1A to be connected to the fourth clamping plate 11.

[0069] Through the above settings, the distance between the third clamping plate 10 and the fourth clamping plate 11 can be flexibly adjusted by the second driving component 12 to clamp workpieces 6 of different sizes in the first direction.
[0070] In some embodiments, in combination with Figure 4 and Figure 7 , first comb-like structures are formed on both sides of the first clamping plate 7 that are opposite and spaced apart along the first direction X, and second comb-like structures are formed on both sides of the second clamping plate 8 that are opposite and spaced apart along the first direction X. In combination with Figure 4 and Figure 8 , third comb-like structures are formed on both sides of the third clamping plate 10 that are opposite and spaced apart in the vertical direction, and fourth comb-like structures are formed on both sides of the fourth clamping plate 11 that are opposite and spaced apart in the vertical direction. The first comb-like structures on both sides of the first clamping plate 7 are in clearance fit with the third comb-like structures on one side of the third clamping plate 10 and the fourth comb-like structures on one side of the fourth clamping plate 11 respectively, and the second comb-like structures on both sides of the second clamping plate 8 are in clearance fit with the third comb-like structures on the other side of the third clamping plate 10 and the fourth comb-like structures on the other side of the fourth clamping plate 11 respectively.
[0071] In combination with Figure 4 , Figure 7 and Figure 8 , when the positions of the third clamping plate 10 and the fourth clamping plate 11 remain unchanged and the first driving component 9 is adjusted to move the first clamping plate 7 and / or the second clamping plate 8 in the vertical direction, the third comb-like structure on the side of the third clamping plate 10 close to the first clamping plate 7 and the fourth comb-like structure on the side of the fourth clamping plate 11 close to the first clamping plate 7 can guide and limit the movement of the first clamping plate 7, and the third comb-like structure on the side of the third clamping plate 10 close to the second clamping plate 8 and the fourth comb-like structure on the side of the fourth clamping plate 11 close to the second clamping plate 8 can guide and limit the movement of the second clamping plate 8.
[0072] In combination with Figure 4 , Figure 7 and Figure 8, when the positions of the first clamping plate 7 and the second clamping plate 8 remain unchanged, and the third clamping plate 10 and / or the fourth clamping plate 11 are moved along the first direction X by adjusting the second driving assembly 12, the first comb tooth structure on the side of the first clamping plate 7 close to the third clamping plate 10 and the second comb tooth structure on the side of the second clamping plate 8 close to the third clamping plate 10 can guide and limit the movement of the third clamping plate 10. The first comb tooth structure on the side of the first clamping plate 7 close to the fourth clamping plate 11 and the second comb tooth structure on the side of the second clamping plate 8 close to the fourth clamping plate 11 can guide and limit the movement of the fourth clamping plate 11.
[0073] Through the above arrangement, when one of the first clamping plate 7, the second clamping plate 8, the third clamping plate 10 and the fourth clamping plate 11 slides, the comb tooth structures of the two adjacent thereto can guide and limit it, so as to maintain the stability when the first clamping plate 7, the second clamping plate 8, the third clamping plate 10 and the fourth clamping plate 11 slide.
[0074] In some examples, the first clamping plate 7 and / or the second clamping plate 8 and / or the third clamping plate 10 and / or the fourth clamping plate 11 are multi-layer structures.
[0075] Exemplarily, in combination with Figure 1 and Figure 9 , at this time, the third clamping plate 10 and the fourth clamping plate 11 are multi-layer structures, that is, along the first direction X, the third comb tooth structures of the third clamping plate 10 are arranged in multiple rows, and the fourth comb tooth structures of the fourth clamping plate 11 are arranged in multiple rows.
[0076] In this case, in combination with Figure 4 , when the second driving assembly 12 is an adjusting screw, a push plate is arranged at the end of the adjusting screw close to the third clamping plate 10 / the fourth clamping plate 11, and the push plate is arranged between two adjacent rows of the multiple rows of comb tooth structures; when the adjusting screw drives the third clamping plate 10 / the fourth clamping plate 11 to move, a force can be applied to the third clamping plate 10 / the fourth clamping plate 11 through the push plate, increasing the contact area between the push plate and the third clamping plate 10 / the fourth clamping plate 11, and the acting force can be dispersed, which is beneficial to reducing or avoiding the damage to the third clamping plate 10 / the fourth clamping plate 11 caused by the acting force on the adjusting screw.
[0077] In some embodiments, as shown in Figure 10 and Figure 11 , the third clamping plate 10 and the fourth clamping plate 11 have the same shape. In the direction from the inlet of the clamping channel 5A to the outlet of the clamping channel 5A, the heights of the third comb tooth structure of the third clamping plate 10 and the fourth comb tooth structure of the fourth clamping plate 11 gradually decrease, and the first clamping plate 7 and the second clamping plate 8 gradually approach each other, so that the height of the clamping channel 5A gradually decreases.
[0078] It should be noted that Figure 10 and Figure 11The third clamping plate 10 and the fourth clamping plate 11 shown are both multi-layer structures.
[0079] Through the above settings, the clamping channel 5A is formed into a structure with a wide inlet and a narrow outlet. When the workpiece to be clamped 6 enters the inlet of the clamping channel 5A, the distance between the workpiece to be clamped 6 and the first clamping plate 7 and the second clamping plate 8 is relatively large, which can reduce the resistance when the workpiece to be clamped 6 enters the clamping channel 5A and reduce the wear on the workpiece to be clamped 6. During the process of the workpiece to be clamped 6 moving to the outlet of the clamping channel 5A, the height between the first clamping plate 7 and the second clamping plate 8 gradually decreases, so as to gradually increase the clamping force on the workpiece to be clamped 6 through the first clamping plate 7 and the second clamping plate 8 and maintain the pulling force of the wire clamping device on the workpiece to be clamped 6.
[0080] In some embodiments, at least one of the first clamping plate 7, the second clamping plate 8, the third clamping plate 10 and the fourth clamping plate 11 is provided with an elastic material layer on the surface facing the clamping channel 5A.
[0081] Exemplarily, the material of the elastic material layer is polytetrafluoroethylene.
[0082] Exemplarily, the first clamping plate 7, the second clamping plate 8, the third clamping plate 10 and the fourth clamping plate 11 are all Q235-B steel plates coated with polytetrafluoroethylene on the outside.
[0083] Through the above settings, the wear of the first clamping plate 7, the second clamping plate 8, the third clamping plate 10 and the fourth clamping plate 11 on the workpiece to be clamped 6 can be reduced.
[0084] In some embodiments, the edges of the first clamping plate 7, the second clamping plate 8, the third clamping plate 10 and the fourth clamping plate 11 are provided with rounded corners.
[0085] Through the above settings, the scratching of the first clamping plate 7, the second clamping plate 8, the third clamping plate 10 and the fourth clamping plate 11 on the workpiece to be clamped 6 can be reduced or avoided.
[0086] In some embodiments, as Figure 2 and Figure 3 shown, the wire clamping device further includes a first wire combing frame 13 and a second wire combing frame 14. The first wire combing frame 13 is fixed at the inlet of the lead channel 1A, and the second wire combing frame 14 is fixed at the outlet of the lead channel 1A for supporting and combing the workpiece to be clamped 6.
[0087] Exemplarily, the materials of the first wire combing frame 13 and the second wire combing frame 14 are both polytetrafluoroethylene.
[0088] Exemplarily, comb teeth are provided on both the first wire combing frame 13 and the second wire combing frame 14. When the workpiece to be clamped 6 enters the lead channel 1A, the first wire combing frame 13 can support and comb the workpiece to be clamped 6. When the workpiece to be clamped 6 exits the lead channel 1A, the second wire combing frame 14 can support and comb the workpiece to be clamped 6, thereby preventing the workpiece to be clamped 6 from deforming due to gravity. When the workpiece to be clamped 6 is multiple wires, it can also prevent the multiple wires from crossing each other to protect the external insulation of the wires.
[0089] In some embodiments, as Figure 1 and Figure 2 shown, the wire clamping device further includes: a telescopic support rod 15 and a fixing ring 16. A base is provided at the bottom of the telescopic support rod 15, and the top of the telescopic support rod 15 is fixedly connected to the bottom plate of the U-shaped seat 1. The fixing ring 16 is fixed on the telescopic support rod 15, and an external strap passes through the fixing ring 16 and is fixed on the fixing ring 16 to fix the telescopic support rod 15 through the strap.
[0090] Exemplarily, the column body of the telescopic support rod 15 is a nested structure, so that the height of the telescopic support rod 15 is adjustable, enhancing the applicability of the wire clamping device.
[0091] Exemplarily, the base at the bottom of the telescopic support rod 15 is circular to increase the contact area with the ground, improve the stability of the telescopic support rod 15, and provide reliable support for the U-shaped seat 1 by the telescopic support rod 15. Three reinforcing ribs are provided between the base and the column body of the telescopic support rod 15 to enhance the mechanical strength of the telescopic support rod 15.
[0092] Exemplarily, the fixing ring 16 is welded to the column body of the telescopic support rod 15.
[0093] When using the wire clamping device, the position of the telescopic support rod 15 is fixed by an external strap passing through the fixing ring 16 to maintain the stability of the position of the wire clamping device and facilitate fixing the wire clamping device at different positions.
[0094] Through the above settings, the mechanical strength and stability of the wire clamping device can be enhanced, and the wire clamping device has the characteristic of being movable.
[0095] Embodiment 2:
[0096] The embodiment of the present utility model further provides a coil winding device for winding a wire into a coil of a transformer. The coil winding device includes a wire reel, the wire clamping device in Embodiment 1, and a winding device. The wire clamping device is used to clamp the wire in the wire reel. The winding device is used to wind the wire. After the wire in the wire reel passes through the clamping channel 5A of the clamping member 5 in the wire clamping device, it then enters the winding device for winding.
[0097] Exemplarily, the wire reel, the wire clamping device, and the winding device are fixedly arranged in sequence along a straight line.
[0098] The wire in the wire reel passes through the clamping channel 5A of the clamping member 5 in the wire clamping device and then enters the winding device. After the winding device rotates, it drives the wire to be wound. Since the clamping member 5 can apply pressure to the wire passing through the clamping channel 5A, therefore, when the winding device drives the wire to move, there will be a certain tensile force on the wire.
[0099] It can be understood that by adjusting the clamping force of the clamping member 5 on the wire, an appropriate tensile force can be provided for the wire according to the type of the wire, thereby improving the quality of the transformer coil wound by the winding device and avoiding the wire being stuck on the wire clamping device due to excessive clamping force.
[0100] It should be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
