Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and specifically relates to a novel electric wire drawing machine. Background Technology

[0002] With the rapid development of technology and continuous advancements in motor technology, new, high-efficiency, and energy-saving motors are constantly emerging. To improve efficiency and reduce energy consumption, a large number of old motors will be phased out and replaced with more advanced and energy-efficient ones. As a type of mechanical equipment, motors have a specific service life. Early-installed motors, after prolonged operation, experience severe wear and tear on components, performance degradation, and frequent malfunctions. Continued use poses safety hazards, therefore they are phased out once they reach their service life. Currently, the dismantling of retired motors is mainly done manually, which presents the following problems: Complex physical structure: The stator winding is a key component of the motor. The coils are tightly wound in the iron core slots and are impregnated and dried. They are difficult to disassemble manually and take a long time.

[0003] High safety risks: The slot wedges of the motor windings contain harmful substances such as asbestos, lead, and mercury. These substances may be released during disassembly, posing a health hazard to operators.

[0004] Personnel safety: Manual disassembly typically involves using an electric pick to remove the coil from the silicon steel sheet. This process is difficult and the tools used have a low safety factor, which can easily lead to injuries or fatalities.

[0005] Inconvenient operation: The dismantling process of retired motors is quite complicated and requires operators to have high professional skills and experience. This not only increases the difficulty of operation, but also takes a long time and reduces work efficiency. In actual operation, a slight mistake may lead to personal injury, which in turn affects the progress of motor dismantling.

[0006] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

A wire drawing operation handle 105 is fixedly connected to the upper left of the wire drawing pliers 104. An oil pipe 106 is fixedly connected to the right side of the wire drawing operation handle 105. (The hydraulic system 102 uses existing mature technology, which only needs to meet the requirements of this utility model and will not be described in detail here.)

[0027] A set of lifting guide grooves 108 are provided on both the left and right sides of the rear side of the lifting frame 107.

[0028] A set of roller seats 110 are fixedly connected to the four corners of the upper surface of the support frame 109. The roller seats 110 rotate the support roller 111. A lifting cylinder 112 is fixedly connected to the lower front end of the support frame 109. The lifting cylinder 112 drives the support frame 109 to move up and down before and after the motor stator winding is placed, and slides along the lifting guide slide 108 via the lifting guide slider to assist in the lifting movement.

[0029] An adjusting slide groove 121 is provided on the right side of the left end of the main box 101 of the wire drawing machine. An adjusting screw 122 is rotatably connected to the inner side of the adjusting slide groove 121, which is used to simultaneously drive the two sets of limit buffer seats 200 to move closer or further away and is powered by a motor. The outer side of the adjusting screw 122 has two sets of external threads with opposite directions in a front-rear structure.

[0030] The limiting buffer seat 200 also includes a set of adjusting sliders 201. The rear side of the adjusting slider 201 is provided with an adjusting screw hole 202. The adjusting slider 201 and the adjusting slide groove 121 are mutually movable and fitted. The adjusting screw 122 and the adjusting screw hole 202 are connected by a threaded fit. The right side of the adjusting slider 201 is fixedly connected to the support frame 203. The buffer spring 204 is sleeved and fixed to the outer side of the upper end of the support frame 203. When the wire puller 104 is disassembling the winding by moving it to the right, the right end of the motor stator winding is buffered and limited by the two sets of front and rear limit buffer seats 200.

[0031] Specifically, before disassembling the motor stator winding, the support frame 109 is positioned on the lower side and the motor stator winding is placed above the two sets of support rollers 111.

Then, the wire drawing hydraulic cylinder 103 is controlled to drive the wire drawing pliers 104 to move to the left, and the wire drawing operation handle 105 controls the wire drawing pliers 104 to clamp and release the winding. Next, during disassembly, the wire drawing hydraulic cylinder 103 moves to the right, and the right end is limited by the limit buffer seat 200. It can also drive the motor to rotate the adjusting screw 122 according to the motor specifications. The distance between the two sets of limit buffer seats 200 is adjusted under the threaded engagement with the limit buffer seat 200, thereby completing the disassembly and use of the motor stator winding.

A guide groove 115 is opened on the outer side of the pneumatic column 114 and is connected to the guide frame 118 in a movable fitting structure. A pneumatic conduit 119 is fixedly connected above the pneumatic column 114, and a foot pedal 120 is fixedly connected above the pneumatic conduit 119. During the disassembly process, the circumferential position of the motor stator winding is continuously adjusted. After the adjustment is completed, pressure is applied to the foot pedal 120, so that the compressed gas in the pneumatic conduit 119 drives the plunger to move down, so that the pressure seat 117 is pressed and fixed from above.

[0034] Based on the first embodiment described above, further, during the disassembly process, the operator needs to continuously adjust the circumferential position of the motor stator winding. After the adjustment is completed, pressure is applied to the foot pedal 120, causing the air pressure conduit 119 to compress the gas and drive the plunger to move down, so that the pressure holder 117 is pressed and fixed from above. During the lifting and lowering movement of the pressure holder 117, it moves up and down along the guide groove 115 via the guide frame 118, thereby assisting in disassembly and use.
