Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a coil unified clamping clamp. Background Art

[0002] An electromagnet is a device that generates electromagnetism when electricity is applied. A conductive winding that matches its power is wound around the outside of the iron core. This coil with current flowing through it has magnetism like a magnet, and it is also called an electromagnet. We usually make it into a bar or hoof shape to make the iron core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately when the power is turned off, we often use soft iron or silicon steel materials that demagnetize quickly to make it. Such an electromagnet is magnetic when electricity is applied, and the magnetism disappears when the power is turned off. Electromagnets are extremely widely used in our daily lives, and their invention has also greatly improved the power of generators.

[0003] After the existing electromagnet is wound with a coil, the coil needs to be pressed and glued to prevent the straight part of the coil from being deformed. For example, Chinese patent announcement No. CN207009288U discloses a "flat coil shaping device", which includes a downward pressing shaping mechanism and a plurality of coil clamps; the downward pressing shaping mechanism includes a base, a support frame mounted on the base, and a downward pressing power member fixed on the support frame, and a space for placing the coil clamp is formed between the base and the support frame. Through the downward pressing shaping mechanism and the plurality of coil clamps, the shaping of multiple flat coils can be completed at one time;

[0004] However, in actual use, the existing device needs to additionally be equipped with a power component to provide power for the device. Since the weight of the power component and the device itself, as well as the connected circuits and pipelines, will limit the movement of the device, when the coil is compressed and glued, it is necessary to take the coil out of the device and then transport it to the glue coating mechanism. During this process, the coil compressed in the coil clamp is prone to loosen and deform again. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the weight of the power component and the connected circuits and pipelines will limit the movement of the device, and the coil clamp and the coil removal and gluing will easily cause the coil to loosen and deform, and a unified coil clamp is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A unified coil clamping fixture is designed, comprising a base and an electromagnet, wherein the base is provided with a guide groove, the electromagnet is placed on the guide groove, and a clamping structure is provided at the upper end of the base;

[0008] The electromagnet comprises an iron core and a plurality of coils, and a pressing portion matching with the plurality of coils is fixedly provided at the output end of the clamping structure;

[0009] The clamping structure includes a connecting component, a force applying component and an output component;

[0010] The output assembly includes an output arm and an output shaft. A fixing assembly is arranged between the output shaft and the output arm. The output shaft is fixedly connected to the pressing portion.

[0011] Furthermore, an adjusting slot is provided on the output arm, and the output shaft is movably plugged into the adjusting slot.

[0012] Furthermore, the fixing assembly includes two nuts threadedly connected to the output shaft, the two nuts are respectively arranged at the upper and lower ends of the output arm and clamp the output arm, the output shaft is provided with two gaskets respectively arranged at the upper and lower ends of the output arm, and guide parts cooperating with the output arm are fixedly arranged on both sides of the gasket.

[0013] Furthermore, the connecting assembly includes a supporting seat detachably connected to the base, a supporting frame is provided on the supporting seat, and the output arm is rotatably connected to the supporting frame.

[0014] Furthermore, the force-applying assembly includes a handle rotatably connected to the support frame, and a connecting plate that cooperates with the output arm is rotatably provided on the handle.

[0015] Furthermore, the connecting plate is provided with a slot corresponding to the output arm.

[0016] The coil unified clamping fixture proposed by the utility model has the beneficial effects of:

[0017] In the utility model, a clamping structure is provided on the base to clamp the coil, and multiple coils can be compressed at the same time during the clamping process. The compressed coil will not loosen under the clamping of the clamping structure. The clamp and the compressed coil are simultaneously transported to the gluing mechanism for gluing, which effectively prevents the coil from loosening and deforming.

[0018] Secondly, in the utility model, the clamping structure has its own force-applying component, which drives the connecting plate to rotate by pulling the handle manually, controls the position of the output arm and the output shaft, compresses the coil, and prevents excessive compression by setting a card slot. When the card slot contacts the output arm, the force-applying component reaches a balanced state, and the position of the output arm is fixed, thereby fixing the state of the coil.
