Description

Technical Field

[0001] The utility model relates to the technical field of winding technology, and more specifically, to a winding tool for a micro special motor winding. Background Technique

[0002] A micro special motor refers to a motor with a diameter less than 160 mm or a rated power less than a certain value (such as 750 W), or having special performance and special uses. There are many types of micro special motors, which can generally be divided into 13 categories, such as DC motors, AC motors, self-aligning angle motors, stepping motors, rotary transformers, shaft angle encoders, AC-DC dual-purpose motors, tachogenerators, induction synchros, linear motors, piezoelectric motors, motor sets, and other special motors.

[0003] At present, due to the small volume of micro special motors, the diameter of the coils wound on their windings is usually relatively thin. Therefore, the coils are usually wound on the windings manually. During the manual winding process, due to the relatively thin diameter of the coils, the contact area between the coils and the hand is small when winding manually, which not only makes it difficult to control the coils, but also easily causes hand injuries. In view of this, we propose a winding tool for a micro special motor winding. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a winding tool for a micro special motor winding, so as to solve the technical problems that in the current manual winding process, due to the relatively thin diameter of the coils, the contact area between the coils and the hand is small when winding manually, which not only makes it difficult to control the coils, but also easily causes hand injuries.

[0005] To solve the above technical problems, the utility model provides the following technical solution: a winding tool for a micro special motor winding, including a support component with a winding component arranged inside;

[0006] The winding component includes a control component with swing arm components symmetrically and movably connected inside;

[0007] The support component includes a fixed seat with connecting arms symmetrically constructed on one side. Extension arms are constructed on both the upper surface and the lower surface of the connecting arms, and a shaft hole is opened inside the fixed seat;

[0008] The control component includes a grip with a connecting rod centrally constructed at one end. The connecting rod is rotatably installed in the shaft hole, and a lead screw is constructed and connected at the end of the connecting rod away from the grip. A sliding seat is movably engaged on the outer edge surface of the end of the lead screw, and a connecting shaft is rotatably arranged inside the sliding seat;

[0009] The rocker arm assembly includes a rocker arm body rotatably connected to the extension arm and a connecting rod structure rotatably connected to the connecting shaft, and a limiting clamping plate is fixedly arranged at the end of the rocker arm body.

[0010] By designing the support assembly, the control assembly and the rocker arm assembly, the present utility model clamps the coil through the limiting clamping plate in the rocker arm assembly, and by holding the grip and rotating eccentrically, the coil can be wound around the winding of the micro special motor, which is convenient for controlling the coil of the micro special motor. At the same time, holding through the grip can avoid hand injury during the cash-out process, realizing a stable winding effect on the winding of the micro special motor.

[0011] Preferably, limiting clamping grooves with different diameters are formed on the surface of the limiting clamping plate. The limiting clamping grooves are obliquely formed in the limiting clamping plate, and rounded corner structures are formed on the edges of the limiting clamping grooves and the edges of the limiting clamping plate.

[0012] Preferably, shaft seats are formed on both sides of the rocker arm body. A rotating shaft is fixedly arranged between the extension arms, and a slot hole one for rotatably installing the rotating shaft is formed inside the shaft seat and the rocker arm body.

[0013] Preferably, the connecting rod structure includes symmetrically arranged movable arms. One ends of the symmetrically arranged movable arms are respectively rotatably installed on both sides of the end of the rocker arm body, and a slot hole two for rotatably installing the connecting shaft is formed inside the other ends of the symmetrically arranged movable arms.

[0014] Preferably, a limiting ring is slidably fitted on the outer edge surface of the connecting rod, and magnetic adsorption insertion rods are fixedly arranged in an annular array inside the limiting ring.

[0015] Preferably, magnetic adsorption holes for magnetically adsorbing and inserting the magnetic adsorption insertion rods are formed in an annular array on one side of the fixed seat.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By designing the support assembly, the control assembly and the rocker arm assembly, the present utility model clamps the coil through the limiting clamping plate in the rocker arm assembly, and by holding the grip and rotating eccentrically, the coil can be wound around the winding of the micro special motor, which is convenient for controlling the coil of the micro special motor. At the same time, holding through the grip can avoid hand injury during the cash-out process, realizing a stable winding effect on the winding of the micro special motor, and solving the problems that in the process of manual winding, due to the relatively thin diameter of the coil, the contact area between the coil and the hand is small during manual winding, it is not easy to control the coil, and at the same time, it is easy to cause hand injury.

[0018] 2. The present utility model also forms a 405 obliquely in the limiting clamping plate. Since the 405 is obliquely arranged, when the coil is placed in the 405 and wound around the winding, it can generate a certain resistance to the discharge of the coil, thereby ensuring that the coil can be tightly wound around the winding. At the same time, during the winding process, with the assistance of hand force, the smooth discharge of the coil can also be realized, thus improving the use effect of the tool during the winding process of the winding.

The winding assembly 1 includes a control assembly 3 with swing arm assemblies 4 symmetrically and movably connected inside. The support assembly 2 includes a fixed seat 201 with connecting arms 203 symmetrically constructed on one side. Extension arms 204 are formed on both the upper and lower surfaces of the connecting arms 203. A shaft hole is formed inside the fixed seat 201. The control assembly 3 includes a grip 301 with a connecting rod 302 centrally constructed at one end. The connecting rod 302 is rotatably installed in the shaft hole, and a lead screw 303 is constructed and connected to the end of the connecting rod 302 away from the grip 301. A sliding seat 304 is movably engaged on the outer edge surface of the end of the lead screw 303. A connecting shaft 305 is rotatably arranged inside the sliding seat 304. The swing arm assembly 4 includes a swing arm body 401 rotatably connected to the extension arm 204 and a connecting rod structure rotatably connected to the connecting shaft 305. A limiting clamping plate 404 is fixedly arranged at the end of the swing arm body 401.

[0028] In an embodiment of the present utility model, as Figure 6 shown, limiting clamping grooves 405 with different diameters are formed on the surface of the limiting clamping plate 404. The limiting clamping grooves 405 are obliquely formed inside the limiting clamping plate 404, and rounded corner structures are formed on the edges of the limiting clamping grooves 405 and the edges of the limiting clamping plate 404.

[0029] In an embodiment of the present utility model, as Figures 2-5 shown, shaft seats 402 are constructed on both sides of the swing arm body 401. A rotating shaft 205 is fixedly arranged between the extension arms 204. A slot one for rotatably installing the rotating shaft 205 is formed inside the shaft seats 402 and the swing arm body 401. The connecting rod structure includes symmetrically arranged movable arms 403. One ends of the symmetrically arranged movable arms 403 are respectively rotatably installed on both sides of the end of the swing arm body 401, and a slot two for rotatably installing the connecting shaft 305 is formed inside the other ends of the symmetrically arranged movable arms 403.

[0030] In an embodiment of the present utility model, as Figure 2 and Figure 5 shown, a limiting ring 306 is slidably fitted on the outer edge surface of the connecting rod 302.

[0031] Working principle: This embodiment provides a winding tool for the winding of a special micro-motor. When in use, first pull the limit ring 306 to move on the outer edge surface of the connecting rod 302, so that the magnetic suction plug 307 disengages from the magnetic suction hole 202. Then, fix the position of the support seat assembly 2 with one hand, and hold the handle 301 with the other hand and rotate it. Then, the connecting rod 302 and the lead screw 303 can be rotated. Under the active meshing action of the lead screw 303 and the sliding seat 304, it drives the sliding seat 304 to move axially. Thus, the rocker arm body 401 is driven to contract through the link structure, and the position of the coil is adjusted, so that the coil is clamped and restricted in the limit clamping groove 405. Then, push the limit ring 306, so that the magnetic suction plug 307 is inserted into the magnetic suction hole 202 to realize the limit of the movement of the sliding seat 304. Then, hold the handle 301 and make an eccentric rotation movement, and the coil can be driven to wind around the winding of the special micro-motor, realizing the winding work of the winding.
