Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding, in particular to a transformer winding mould. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. In the production process of the transformer, winding is one of the more important steps. When winding the transformer, a corresponding winding mold is required. The winding mold is a winding machine. The winding machine is a device that winds a linear object onto a specific workpiece. It is usually used for copper wire winding. Most electrical products need to be wound into an inductor coil with enameled copper wire (enameled wire for short). Winding can be used. The winding machine completes one or more processes, for example: various motors, hollow cup motors, rotors, stators, pin inductors, chip inductors, transformers, solenoid valves, single-word inductors, resistors, ignition coils, RFID, mutual inductors, audio coils, IC card high and low frequency coils, focusing coils, etc. There are many types of winding machines, which can be divided into general and special types according to their uses; the general type is suitable for winding machines for a variety of products, and it can correspond to the processing of different products by replacing the corresponding molds and instructions. The special type is a winding machine for a specific product. The transformer winding mold refers to the winding equipment for winding the transformer wire.

[0003] According to the announcement number: CN219677051U, a new transformer winding mold is disclosed, which relates to the technical field of transformer winding molds. The utility model includes a mounting plate, a mounting frame is welded on the upper surface of the mounting plate, a rotating sleeve is welded on one side of the mounting frame, and a power shaft is installed on one side of the rotating sleeve. The utility model installs a threaded rod, controls the handle to rotate, and drives the threaded rod to rotate through the rotating shaft. The threaded rod and the moving block are connected by bolts, and the limit groove and the limit rod are slidably matched to limit the position of the moving block so that it can only move left and right. When the threaded rod rotates forward or reversely, the moving block can be driven to move left and right. The sliding devices with the same structure are installed on both sides of the threaded rod, but the threads on both sides of the threaded rod are opposite. When in use, the control handle rotates forward to gather the moving blocks on both sides to the middle, and at the same time drive the winding block. However, when the handle is rotated in the reverse direction, its moving blocks are spread out to both sides, and the adjustable winding block is set to adjust according to needs.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem in the prior art that the winding mold structure is fixed and a single winding mold can only correspond to winding a coil of one specification, when the coil size needs to be adjusted, the winding mold needs to be replaced, which is not only time-consuming and labor-intensive, but also increases the cost of use.

[0005] However, in actual use, it was found that when winding the wire, since there is no winding traction structure, manual control of the wire direction is required. However, the efficiency of manual traction is usually low because it depends on the operator's skills and speed, which may become an efficiency bottleneck when producing large quantities of products. Manual traction is also difficult to ensure the consistency and accuracy of each winding, because human factors may cause slight differences in the coils wound each time, which is not conducive to products requiring high precision. Summary of the invention

[0006] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a transformer winding mold, which has the advantages of traction and solves the problem that there is no winding traction structure during winding, and thus manual control of the direction of the wire is required. However, the efficiency of manual traction is usually low because it depends on the operator's skills and speed, which may become an efficiency bottleneck when producing large quantities of products. In addition, manual traction is difficult to ensure the consistency and accuracy of each winding because human factors may cause slight differences in the coils wound each time.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer winding mold, comprising a base, a power device and a winding group, the power device is fixedly installed on the left side of the top of the base, the winding group is movably connected to the top of the right side of the power device, the left side of the rear side of the top of the base is fixedly connected to a driving motor, the output end of the driving motor is fixedly connected to a reciprocating screw, the surface of the reciprocating screw is threadedly connected to a moving block, the back of the moving block is fixedly connected to a traction assembly, the front of the moving block is fixedly connected to an adjustment mechanism, and the bottom of the moving block is fixedly connected to a limiting assembly.

[0010] As a preferred embodiment of the utility model, the limit assembly includes a limit block, the limit block is fixedly connected to the bottom of the moving block, and the interior of the limit block is slidably connected to the limit rod via a through hole.

[0011] As a preferred embodiment of the present invention, the fixing assembly includes a threaded hole, the threaded hole is opened on the front side of the mounting block, the threaded hole is connected to the adjustment slot, and the internal thread of the threaded hole is connected to a screw rod.

[0012] As a preferred embodiment of the utility model, the left and right sides of the surface of the reciprocating screw rod are movably connected to support plates via bearings, and the bottom of the support plate is fixedly connected to the base.

[0013] As a preferred embodiment of the present invention, the left end and the rear side of the limit rod are fixedly connected to the support plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a driving motor, a reciprocating screw, a moving block and a traction assembly. The driving motor drives the reciprocating screw to rotate, and then the rotating reciprocating screw drives the moving block to move, so that the moving block drives the traction assembly to move, and then the traction assembly drives the copper wire to traction and winding, thereby ensuring the uniformity and convenience of winding. When the moving block moves to the end point of the reciprocating screw, the moving block will change the moving direction through the internal crescent pin, so as to realize reciprocating winding, and solves the problem that when winding, there is no winding traction structure, and thus manual control of the direction of the wire is required. However, the efficiency of manual traction is usually low because it depends on the skills and speed of the operator, which may become an efficiency bottleneck when producing large quantities of products, and manual traction is difficult to ensure the consistency and accuracy of each winding because human factors may cause slight differences in the coils wound each time, thereby achieving the traction effect.

[0016] 2. The utility model uses a traction assembly. When the operator needs to control the winding direction through the reciprocating screw rod, the operator passes the copper wire through the inside of the traction ring. When the reciprocating screw rod rotates to drive the moving block to move, the moving block drives the support rod and the traction ring to move, so that the traction ring can drive the copper wire to move, thereby ensuring that the copper wire can move with the moving block.

[0017] 3. The utility model sets an adjustment mechanism, and performs the winding work by passing the copper wire through the traction ring and the adjustment ring in sequence. When the operator needs to adjust the winding tension, the operator moves the adjustment plate upward or downward, and then the adjustment plate drives the adjustment ring to move. When the adjustment ring is lower than the height of the traction ring, the copper wire will increase the inflection point angle, thereby increasing the copper wire tension. When the adjustment ring is higher than the height of the traction ring, the copper wire will reduce the inflection point angle, thereby reducing the copper wire tension, thereby improving the convenience of the operator in adjusting the winding tension.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] As a technical optimization solution of the utility model, through the traction component 7, when the operator needs to control the winding direction through the reciprocating screw rod 5, the operator passes the copper wire through the inside of the traction ring 72. When the reciprocating screw rod 5 rotates to drive the moving block 6 to move, the moving block 6 drives the support rod 71 and the traction ring 72 to move, so that the traction ring 72 can drive the copper wire to move, thereby ensuring that the copper wire can move with the moving block 6.

An adjustment ring 84 is fixedly connected to the top of the adjustment plate 83. A fixing component 85 is provided on the front side of the mounting block 81.

[0028] As a technical optimization scheme of the utility model, by setting the adjustment mechanism 8, the copper wire is passed through the traction ring 72 and the adjustment ring 84 in turn to perform the winding work. When the operator needs to adjust the tension of the winding, the operator moves the adjustment plate 83 upward or downward, and then the adjustment plate 83 drives the adjustment ring 84 to move. When the adjustment ring 84 is lower than the height of the traction ring 72, the copper wire will increase the inflection point angle, thereby increasing the tension of the copper wire. When the adjustment ring 84 is higher than the height of the traction ring 72, the copper wire will reduce the inflection point angle, thereby reducing the tension of the copper wire, thereby improving the convenience of the operator to adjust the winding tension.

[0029] refer to Figure 3 The limiting assembly 9 includes a limiting block 91, which is fixedly connected to the bottom of the moving block 6, and a limiting rod 92 is slidably connected to the interior of the limiting block 91 through a through hole.

[0032] As a technical optimization solution of the utility model, by setting a fixing component 85, when the operator moves the adjustment plate 83, the operator turns the screw 852, so that the screw 852 presses the adjustment plate 83 through the threaded groove, thereby ensuring the stability of the adjustment plate 83 after movement.

[0033] refer to Figure 2 The left and right sides of the surface of the reciprocating screw rod 5 are movably connected to support plates 10 through bearings, and the bottom of the support plate 10 is fixedly connected to the base 1.

[0034] As a technical optimization solution of the utility model, a support plate 10 is provided so that the support plate 10 and the base 1 are fixedly installed, and then the reciprocating screw rod 5 is movably installed on the support plate 10 through a bearing, so that the support plate 10 supports the reciprocating screw rod 5, thereby enabling the reciprocating screw rod 5 to rotate stably.

[0035] refer to Figure 2 The left end and the rear side of the limiting rod 92 are fixedly connected to the supporting plate 10 .

[0036] As a technical optimization solution of the present invention, by fixing the limit rod 92 and the support plate 10 , the support plate 10 can support the limit rod 92 , thereby providing necessary conditions for the use of the limit rod 92 .

[0037] The working principle and use process of the utility model are as follows: during use, when the operator needs to perform winding work, the operator inserts the workpiece into the winding group 3, and the operator sequentially passes the copper wire through the traction ring 72 and the adjustment ring 84, and then fixes one end of the copper wire on the workpiece, and the operator starts the power device 2 and the drive motor 4, so that the power device 2 drives the workpiece on the surface of the winding group 3 to rotate and wind the wire. While winding the wire, the drive motor 4 will also drive the reciprocating screw rod 5 to rotate through the bearing and the support plate 10, and the rotating reciprocating screw rod 5 will drive the moving block 6 to move through the limit rod 92 and the limit block 91, and then the moving moving block 6 drives The traction ring 72 and the adjustment ring 84 on the surface move, so that the traction ring 72 and the adjustment ring 84 drive the copper wire to move, so as to pull the winding direction of the copper wire and ensure the uniformity of the winding. When the operator needs to adjust the tension of the winding, the operator moves the adjustment plate 83 upward or downward, and then the adjustment plate 83 drives the adjustment ring 84 to move. When the adjustment ring 84 is lower than the height of the traction ring 72, the copper wire will increase the inflection point angle, thereby increasing the tension of the copper wire. When the adjustment ring 84 is higher than the height of the traction ring 72, the copper wire will reduce the inflection point angle, thereby reducing the tension of the copper wire, thereby improving the convenience of the operator to adjust the winding tension.

[0038] To sum up: this transformer winding mold, by setting a driving motor 4, a reciprocating screw 5, a moving block 6 and a traction assembly 7, the driving motor 4 drives the reciprocating screw 5 to rotate, and then the rotating reciprocating screw 5 drives the moving block 6 to move, so that the moving block 6 drives the traction assembly 7 to move, and then the traction assembly 7 drives the copper wire to traction winding, ensuring the uniformity and convenience of winding. When the moving block 6 moves to the end point of the reciprocating screw 5, the moving block 6 will change the moving direction through the internal crescent pin, so as to realize reciprocating winding, which solves the problem that when winding, there is no winding traction structure, and thus manual control of the direction of the wire is required. However, the efficiency of manual traction is usually low because it depends on the operator's skills and speed, which may become an efficiency bottleneck when producing large quantities of products, and manual traction is difficult to ensure the consistency and accuracy of each winding because human factors may cause slight differences in the coils wound each time.
