[0019] Figure 1 It is a coil unwinding device provided by an embodiment of the present utility model. Detailed Embodiment
[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0021] Please refer to Figure 1 ,like Figure 1 As shown, an embodiment of the utility model provides a coil unwinding device for unwinding a failed electromagnetic coil, and the coil unwinding device comprises: a bracket 10, a winding mechanism and a driving mechanism 50, wherein the bracket 10 is used to support the winding mechanism, that is, the winding mechanism is rotatably arranged on the bracket 10; the driving mechanism 50 is transmission-connected with the winding mechanism, and the driving mechanism 50 is used to drive the winding mechanism to rotate, and then the winding mechanism will wind up the wire unwound from the coil.
[0022] Specifically, the winding mechanism in this embodiment includes a first clamping assembly and a second clamping assembly, wherein the first clamping assembly includes a first main shaft 21 and a first clamping block 22 fixedly arranged at one end of the first main shaft 21, and the second clamping assembly includes a second main shaft 31, a second clamping block 32 clamped at one end of the second main shaft 31, and an elastic assembly 33 arranged on the second main shaft 31, wherein the elastic assembly 33 can push the second clamping block 32 to move along the axial direction of the second main shaft 31 so that the second clamping block 32 is abutted and fixed with the first clamping block 22. Among them, the first main shaft 21 and the second main shaft 31 are coaxially arranged, the ends of the first clamping block 22 and the second clamping block 32 are concave-convex matched, and a winding groove 40 is formed between the first clamping block 22 and the second clamping block 32.
[0023] Thus, the first main shaft 21 and the second main shaft 31 are rotatably connected to the bracket 10, and the first clamping block 22 on the first main shaft 21 and the second clamping block 32 on the second main shaft 31 are matched in a concave-convex manner, and a holding force is applied by the elastic component 33 so that the second clamping block 32 and the first clamping block 22 are held and fixed, and a winding groove 40 for accommodating the wire withdrawn from the coil is formed between the first clamping block 22 and the second clamping block 32.
[0024] In this embodiment, when winding is required, the coil can be inserted into a fixed shaft. The coil can rotate around the fixed shaft. Then, the second clamping block 32 is pushed away from the first clamping block 22, causing the elastic component 33 to contract. Next, the wire head of the coil is inserted between the first clamping block 22 and the second clamping block 32. After that, the second clamping block 32 is released, so that the second clamping block 32 is pushed by the elastic force of the elastic component 33 to abut and fix against the first clamping block 22. Finally, the driving mechanism 50 drives the winding mechanism to rotate, and the wire unwound from the coil is gradually wound into the winding groove 40 formed between the first clamping block 22 and the second clamping block 32. When the winding is completed, the second clamping block 32 is pushed away from the first clamping block 22, so that the first clamping block 22 and the second clamping block 32 are separated, and the wire wound between them can be detached and removed, which is convenient and fast.
[0025] Therefore, in the present utility model, by using the elastic component 33 to push the second clamping block 32 to abut and fix against the first clamping block 22 to form the winding groove 40, and the driving mechanism 50 drives the winding mechanism to rotate, efficient winding can be achieved. After the winding is completed, the second clamping block 32 is pushed away from the first clamping block 22, and the wound wire can be taken out. The disassembly is convenient.
[0026] In some embodiments, optionally, the elastic component 33 includes a stop block 332 and an elastic member 331. Among them, the stop block 332 is fixedly arranged on the outer periphery of the main shaft, and the elastic member 331 is arranged between the second clamping block 32 and the stop block 332. One end of the elastic member 331 is connected to the side of the second clamping block 32 facing away from the first clamping block 22, and the other end of the elastic member 331 is connected to the stop block 332. The method of using the elastic member 331 to fix the second clamping block 32 can not only conveniently clamp the wire head, but also quickly take out the wound wire by pushing the second clamping block 32 after the winding is completed, and the disassembly is convenient.
[0027] Optionally, the elastic member 331 is a spring. The spring can be sleeved outside the second main shaft 31 to ensure that an axial pushing force is provided and it is not easy to generate offset.
[0028] In some embodiments, optionally, the second clamping block 32 is clamped on one end of the second main shaft 31 through a positioning key 34, and the second clamping block 32 can move axially along the second main shaft 31. Exemplarily, the positioning key 34 and the second main shaft 31 are in interference fit, and the second clamping block 32 is clamped with the second main shaft 31 through the positioning key 34. The second clamping block 32 has a certain range of movement, that is, the second clamping block 32 can move in the axial direction of the second main shaft 31, so as to approach or move away from the first clamping block 22.
[0029] In some other embodiments, optionally, the bracket 10 includes a first upright column 11 and a second upright column 12. Among them, a first bearing is provided at the top of the first upright column 11, and a second bearing is provided at the top of the second upright column 12. One end of the first main shaft 21 away from the first clamping block 22 is rotatably connected to the first bearing, and one end of the second main shaft 31 away from the second clamping block 32 is rotatably connected to the second bearing. Thus, the rotatable connection between the first main shaft 21 and the second main shaft 31 and the bracket 10 can be conveniently realized, that is, the winding mechanism can rotate on the bracket 10, thereby facilitating winding.
[0030] In some embodiments, optionally, the driving mechanism 50 includes a motor 51 and a transmission mechanism 52. The motor 51 is in transmission connection with the second main shaft 31 through the transmission mechanism 52. Exemplarily, the transmission mechanism 52 can be a belt. By means of driving by the motor 51, the automatic rotation of the winding mechanism can be realized, and then the automatic winding function can be realized, without manual winding, which greatly improves the efficiency of wire unwinding and rewinding. Of course, in specific implementation, the transmission mechanism 52 can also be connected to the first main shaft 21, and this embodiment does not specifically limit it.
[0031] In some other embodiments, optionally, the driving mechanism 50 includes a hand crank and a belt. The hand crank is in transmission connection with the second main shaft 31 through the belt. By rotating the hand crank to wind the winding mechanism, while improving the winding efficiency, the winding condition of the wire in the winding groove 40 can be adjusted in real time and conveniently, so as to avoid the problem of excessive winding on one side.
[0032] In some embodiments, optionally, at least one of the first clamping block 22 and the second clamping block 32 is made of rubber. That is to say, the first clamping block 22 and / or the second clamping block 32 can be rubber blocks. The rubber blocks are lighter in weight, which can prevent the first main shaft 21 and the second main shaft 31 mainly subjected to axial forces from bearing too much longitudinal force. Moreover, the first clamping block 22 and the second clamping block 32 made of rubber fit more closely, and can better clamp the wire head.
[0033] In some embodiments, optionally, the end face of the first clamping block 22 facing the second clamping block 32 is provided with a central groove, and the end face of the second clamping block 32 facing the first clamping block 22 is provided with a central protrusion, and the central protrusion coincides with the central groove. Thus, the abutting and fixing between the first clamping block 22 and the second clamping block 32 can be realized, and the longitudinal displacement between the two can be avoided. The concave-convex mating surfaces of the two can also be used to conveniently clamp the wire head. A wire hole or a wire groove can be provided on the groove wall of the central groove, so that the wire head can extend into the central groove through the wire hole or the wire groove. When the central protrusion is inserted into the central groove, the wire head extending into the central groove can be fixed, which is convenient for winding the wire.
[0034] In some embodiments, optionally, the first clamping block 22 is fixedly connected to the first main shaft 21 in an interference fit. The interference fit method does not require additional fixing parts, making the overall structure simpler and lighter.
[0035] In summary, in the present utility model, by using the elastic component to push the second clamping block to abut and fix with the first clamping block to form a winding groove, and the driving mechanism drives the winding mechanism to rotate, efficient winding can be achieved. After winding is completed, the second clamping block is pushed away from the first clamping block, and then the coil can be taken out, and the disassembly is convenient.
