Description

Technical Field

[0001] This utility model belongs to the field of winding tooling technology, and in particular, relates to a winding machine rotating sleeve and a winding machine. Background Technology

[0002] Large couplings are required for torque testing of large motors, especially ultra-large motors (such as those used in large ships). The specific working principle is as follows: The coupling is heated in a high-temperature furnace, causing its bore to expand and increase in size. The heated coupling is then fitted onto the output shaft of the motor under test in a tight fit. A key is forcefully inserted into the corresponding keyways on the output shaft and the coupling. After cooling, the coupling is tightly fitted onto the output shaft. The motor shaft of the test motor is connected to the coupling to perform the torque test. After the test, the coupling needs to be removed from the output shaft of the tested motor. Because the coupling is fitted onto the output shaft with a near-interference fit, it is impossible to remove it using a strong pulling device. Therefore, it is necessary to heat it before pulling to increase its bore size. Obviously, it is impossible to heat the coupling in a high-temperature furnace at this point.

[0003] Existing winding fixtures are too complex to be used on marine motors. Workers evenly wind wire around the outer circumference of the coupling sleeve to form a heating electromagnetic coil, which then uses a strong current to electromagnetically heat the coupling. Because large couplings have long sleeve diameters, one turn of the wire can be two meters long, typically requiring 20 to 40 turns, totaling 40 to 100 meters of wire. This necessitates at least two workers repeatedly winding and dragging the wire at a height of nearly 2 meters above the ground for an extended period, which is time-consuming, labor-intensive, and inefficient.

[0004] A patent with publication number CN103474229A discloses a winding fixture for high-power, high-current inductor coils, including a motor. The output end of the motor is connected to a winding shaft via a coupling. The winding shaft is connected to a screw via a transmission mechanism. The screw is threaded to the two side walls of a mounting base. A guide rod is also installed between the two side walls of the mounting base. A fixing block is installed on the guide rod. A first fixing plate and a second fixing plate are fixed to two mutually perpendicular sides of the fixing block, respectively. One end of a pressure plate is hinged to the middle of the first fixing plate, and the other end of the pressure plate is fixed to the screw. One end of the screw is threaded to a connecting plate, and the connecting plate is hinged to a pressure plate turntable. The fixture structure disclosed in this patent is relatively complex and its size is too large to be used on marine motors. Utility Model Content

[0005] This invention addresses the problem that existing winding fixtures are too complex and unsuitable for use on marine motors. Workers uniformly wind wire around the outer circumference of the coupling sleeve to form a heating electromagnetic coil, which then uses a strong current to electromagnetically heat the coupling. Because large couplings have long sleeve diameters, one turn of the wire can be up to two meters long, typically requiring 20-40 turns, totaling 40-100 meters of wire. This necessitates at least two workers repeatedly winding and dragging the wire from a height of nearly 2 meters above the ground for an extended period, resulting in time-consuming, labor-intensive, and inefficient work. This invention provides a winding device and a winding mechanism.

[0006] To address the aforementioned technical problems, the technical solution of this utility model is as follows:

[0007] A winding coil sleeve is mounted on the outer circumference of a coupling bushing and is rotatable relative to the bushing; the winding coil sleeve is composed of half sleeve one and half sleeve two; the inner sides of half sleeve one and half sleeve two are provided with flange one and flange two, which are joined together to form a flange.

[0008] Furthermore, one side of the first half-set is hinged to one side of the second half-set via a hinge shaft, and the other side of the first half-set is bolted to the other side of the second half-set, so that the first half-set and the second half-set can rotate and open around the hinge shaft.

[0009] Furthermore, the hinge shaft is located between one side of flange flange one and one side of flange flange two, and the bolt is located between the other side of flange flange one and the other side of flange flange two.

[0010] Furthermore, flange one and flange two form a semi-circular shape, and flange one and flange two are arranged symmetrically.

[0011] Furthermore, the length of the winding device's rotating sleeve is less than the length of the bushing tube.

[0012] Furthermore, the outer circumference of the winding device is provided with a sleeve and a limiting member. The limiting member consists of an insert rod and an L-shaped outer stop post, which is used to restrict the electrical wires on the winding device during the winding process.

[0013] Furthermore, the inner side of the sleeve is provided with radially outward inner baffles.

[0014] Furthermore, the inner end of the insertion rod is close to the flange edge, and a gap of at least one wire diameter is left between the inner end of the sleeve and the flange edge. The inner end of the insertion rod is exposed at this gap, and a groove is provided on the surface of the exposed part.

[0015] Furthermore, a pressure post is provided on the flange edge located on the side of the winding machine sleeve. The inner end of the pressure post is fixed on the flange edge, and the outer end extends axially by a distance equal to the diameter of an electrical wire. The distance between the pressure post and the winding machine sleeve is greater than the diameter of the electrical wire, and there is an axial gap between the pressure post and the sleeve.

[0016] A winding device, comprising the winding device sleeve described above.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The winding sleeve of this utility model is installed on the outer circumference of the bushing tube of the coupling and can rotate relative to the bushing tube. The winding sleeve consists of half sleeve one and half sleeve two. Flange one and flange two are provided on the inner sides of half sleeve one and half sleeve two, which are joined to form flanges. This utility model relates to a large coupling, which has a bushing tube with a connecting flange at one end. The electrical wire is broken into a connecting section and a winding section. The broken end of the winding section (end one) and the broken end of the connecting section (end two) are detachably connected. The broken end of the winding section (end one) is fixed on the winding sleeve already fitted around the bushing tube. The electrical wire is wound on the bushing tube by rotating the winding sleeve. The winding time is only a few minutes, eliminating the need for several people to repeatedly wind tens of meters of electrical wire on the bushing tube, increasing work efficiency by tens of times and greatly reducing the labor intensity of workers. The winding mechanism of this utility model is simple and easy to manufacture. Attached Figure Description

[0033] Example 1

[0034] like Figures 1 to 8 As shown, a winding sleeve 1 is used to wind electrical wires to form a heating electromagnetic coil on a large coupling. The winding sleeve 1 is installed on the outer circle of the bushing tube 41 of the coupling 4 and can rotate relative to the bushing tube 41. The winding sleeve 1 is composed of half sleeve one 11 and half sleeve two 12. The inner sides of half sleeve one 11 and half sleeve two 12 are provided with flange one 131 and flange two 132, which are joined together to form flanges.

[0035] like Figure 1 and Figure 3 As shown, the length of the winding sleeve 1 is less than the length of the bushing 41, so that the winding sleeve 1 can only be fitted onto a section of the bushing 41. Its function is to transfer the pre-wound coil 212 wound on the winding sleeve 1 to the left blank section 411, so that the winding sleeve 1 can be removed. One end of the bushing 41 is provided with a connecting flange 42.

[0036] like Figure 1As shown, one side of half-set 11 and one side of half-set 2 12 are hinged together by hinge shaft 14, and the other side of half-set 11 and the other side of half-set 2 12 are fastened together by bolts 15. Removing bolts 15 allows half-set 11 and half-set 2 12 to rotate and open around hinge shaft 14, facilitating easy mounting and disassembly from coupling 4. The inner ends of half-set 11 and half-set 2 12 have symmetrical semi-annular flanges 131 and 132, which together form flange 13. The flange 13 increases the structural strength of the entire winding sleeve 1 and facilitates the installation of some load-bearing components. Hinge shaft 14 is located between one side of flange 131 and one side of flange 2 132, and bolts 15 are located between the other side of flange 131 and the other side of flange 2 132.

[0037] like Figures 1 to 5 As shown, a sleeve 16 with a rectangular tube hole is axially arranged on the outer circle of the winding coil 1. A limiting member 17, consisting of an insert rod 172 and an outer stop post 171 in an L-shape, is provided to restrict the pre-wound coil 212 on the winding coil 1 during the winding process. The insert rod 172 has a rectangular cross-section, allowing it to be inserted into the sleeve 16 for fixation and to be pulled out of the sleeve 16 after being released from fixation. In application, the outer stop post 171 extends radially outward from the outer end of the winding coil 1. The inner end of the insert rod 172 is close to the flange edge 13, and a gap of at least one conductor diameter is left between the inner end of the sleeve 16 and the flange edge 13. The inner end of the insert rod 172 is exposed at this gap, and a groove 1721 is provided on the surface of the exposed part. A pressure post 18 is provided on the flange 13 on the side of the winding coil 1. The inner end of the pressure post 18 is fixed to the flange 13, and the outer end extends axially by the diameter of a wire 2. There is at least one wire 2 diameter between the pressure post 18 and the winding coil 1. There is an axial gap between the pressure post 18 and the sleeve 16. In application, the end 211 of the winding section 21 is pressed between the pressure post 18 and the winding coil 1. The wire 2 wound for the first turn is radially pressed into the groove 1721 provided at the inner end of the insertion rod 172, thus axially fixing the insertion rod 172. An inner stop post 161 is provided radially outward at the inner end of the sleeve 16, so that the first turn of the pre-wound coil 212 is located between the flange 13 and the inner stop post 161, and the rest is wound between the inner stop post 161 and the outer stop post 171.

[0038] The term "inner end" refers to the end of the winding coil 1 that is close to the flange edge 13, while "outer end" refers to the end of the winding coil 1 that is close to the blank section 411 of the bushing tube.

[0039] Example 2

[0040] like Figures 5 to 8As shown, in this embodiment, before the winding operation, the electrical conductor 2 is first disconnected into a connecting segment 22 and a winding segment 21. The disconnected end 211 of the winding segment 21 and the disconnected end 221 of the connecting segment 22 are configured as a detachable movable connection. In this way, the electrical conductor can be disconnected during winding and reconnected to provide power after winding is completed.

[0041] The principle of using the winding device of this application to wind electrical wires on large couplings is as follows:

[0042] S1, such as Figure 3 As shown, the manufactured winding sleeve 1 is detachably fitted onto the outer circle of one end of the bushing tube 41, leaving the other end of the bushing tube 41 as a blank section 411;

[0043] S2, such as Figure 4 , 5 As shown, the end 211 of the wire winding section 21 is fixed on the winding machine sleeve 1, and the winding machine sleeve 1 is rotated to make the winding section 21 be wound on the winding machine sleeve 1 into a pre-wound coil 212 that meets the set number of turns.

[0044] S3, such as Figure 6 As shown, the pre-wound coil 212 wound on the winding machine sleeve 1 is pulled to the blank section 411 of the bushing tube 41, so that the winding machine sleeve 1 is exposed; and the winding machine sleeve 1 is removed from the bushing tube 41.

[0045] S4, such as Figure 7 and Figure 8 As shown, the pre-wound coil 212, which was pulled to the blank section 411 of the bushing 41, is rearranged on the entire bushing 41 and the pre-wound coil 212 is tightened to form a qualified electromagnetic coil 213.

[0046] Example 3

[0047] like Figure 1 As shown, multiple radially outward rotating grips 19 are provided on the outer periphery of the flange edge 13. When winding the wire, the winding sleeve 1 can be easily rotated simply by turning the rotating grips 19. The insertion rod 172 can also be fixed to the sleeve 16 with screws.

[0048] Obviously, the above-described embodiments of this utility model are merely examples for clearly illustrating this application and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
