Description

Technical Field

[0001] This utility model relates to the field of iron core processing technology, and in particular to a high-performance motor iron core sample processing structure. Background Technology

[0002] Wire EDM is a precision machining process that cuts metal materials using the principle of electrical discharge. Its core principle is to utilize the high temperature generated by the electrical discharge to locally melt or vaporize the workpiece material, thereby achieving material removal and cutting. Wire EDM typically uses fine metal wires (such as molybdenum or copper wires) as electrodes, powered by a pulsed power supply, and uses a working fluid (such as a saponifying solution) for cooling and chip removal. Therefore, it is widely used in high-precision manufacturing fields such as aerospace, medical, mold making, and electronics. Existing silicon steel sheets are usually shaped using wire EDM. During the wire EDM process, iron slag waste is generated to varying degrees. This iron slag waste adheres to the silicon steel sheet, making it impossible to clean completely. This creates a conductive connection between the iron slag waste and the silicon steel sheet, preventing separation and magnetic insulation, increasing eddy current losses, and thus affecting the machining quality. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a high-performance motor core sample processing structure.

A glue dispensing machine is disposed on the side of the machine base. The stacking assembly includes a first clamping plate, a second clamping plate spaced apart from the first clamping plate, and fasteners disposed between the first clamping plate and the second clamping plate. The first clamping plate is provided with a through hole so that the workpiece to be processed can be accommodated between the first clamping plate and the second clamping plate, and the position between the first clamping plate and the second clamping plate is pressed and locked by the fasteners.

[0005] Preferably, the fastener includes a fastening bolt and a fastening nut disposed on the fastening bolt, wherein the fastening bolt passes through the second clamping plate and the first clamping plate in sequence and is threadedly connected to the fastening nut.

[0006] Preferably, the machine tool is provided with a conveying channel, which is arranged along the length of the machine tool, and the second clamping plate is slidably connected in the conveying channel.

[0007] Preferably, positioning components are provided on both sides of the machine tool.

Detailed Implementation

[0014] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] like Figures 1 to 2As shown, a high-performance motor core sample processing structure of the present invention includes a machine base 1 and a stacking assembly 2 disposed on the machine base 1. A glue dispensing machine 3 is disposed on the side of the machine base 1. The stacking assembly 2 includes a first clamping plate 21, a second clamping plate 22 disposed at a distance from the first clamping plate 21, and a fastener 23 disposed between the first clamping plate 21 and the second clamping plate 22. The first clamping plate 21 is provided with a through hole 24 so that the workpiece to be processed is accommodated between the first clamping plate 21 and the second clamping plate 22, and is pressed and locked between the first clamping plate 21 and the second clamping plate 22 by the fastener 23.

[0017] During operation, multiple stacked silicon steel sheets are placed between the first clamping plate 21 and the second clamping plate 22, and then fastened and locked in place by fasteners 23. This strengthens the clamping of the stacked silicon steel sheets between the first clamping plate 21 and the second clamping plate 22, making it difficult for the stacked silicon steel sheets to loosen or fall off. Next, the dispensing machine 3 is started to inject epoxy resin into the through hole 24. Since the through hole 24 is set through the first clamping plate 21, the epoxy resin penetrates downward along the through hole 24 and permeates into each silicon steel sheet. Because the surface of each silicon steel sheet is coated with a layer of epoxy resin... The epoxy resin adhesive allows iron slag generated during subsequent wire EDM processes to adhere to the adhesive, effectively separating the iron slag from the silicon steel sheets and significantly reducing eddy current losses. Furthermore, during the disassembly and cleaning of the first clamping plate 21 and the second clamping plate 22 after wire EDM, the silicon steel sheets release stress during disassembly, which could lead to increased stacking coefficients or cracking. The adhesive properties of the epoxy resin ensure even stress distribution between adjacent silicon steel sheets, preventing cracking due to uneven stress during disassembly, reducing the stacking coefficient, and ensuring the structural stability of multiple stacked silicon steel sheets. This invention, by injecting epoxy resin, prevents iron slag from adhering to multiple stacked silicon steel sheets during wire EDM, effectively reducing eddy current losses and improving processing quality.

[0018] The fastener 23 in this embodiment includes a fastening bolt 25 and a fastening nut 26 disposed on the fastening bolt 25. The fastening bolt 25 passes through the second clamping plate 22 and the first clamping plate 21 in sequence and is threadedly connected to the fastening nut 26. Specifically, the fastening bolt 25 passes through the second clamping plate 22 and the first clamping plate 21 from bottom to top and is then threadedly connected to the fastening nut 26, which can complete the position fixing operation between the first clamping plate 21 and the second clamping plate 22. The operation is simple and convenient, and the fastening effect is good.

[0019] In this embodiment, the machine base 1 is provided with a conveying channel 11, which is arranged along the length direction of the machine base 1. The second clamping plate 22 is slidably connected in the conveying channel 11. Specifically, the conveying channel 11 is arranged along the length direction of the machine base 1 so that the second clamping plate 22 can slide into the machine base 1 along the conveying channel 11 and move accordingly to the bottom of the dispensing machine 3, so that the dispensing machine 3 can inject epoxy resin into the laminated assembly 2.

[0020] In this embodiment, positioning components 4 are provided on both sides of the machine base 1. Each positioning component 4 includes a positioning plate 41 and positioning screws 42 disposed on the positioning plate 41. A hinge shaft 43 is provided at the connection between the positioning plate 41 and the machine base 1. The machine base 1 is provided with a fixing hole 12 so that the positioning screws 42 pass through the positioning plate 41 and connect with the fixing hole 12. The positioning plate 41 presses against the second clamping plate 22. Specifically, the positioning plate 41 rotates around the machine base 1 via the hinge shaft 43. When the second clamping plate 22 slides along the conveying channel 11 to the bottom of the dispensing machine 3, the positioning plate 41 rotates around the hinge shaft 43 and accurately presses against the second clamping plate 22. Then, the positioning screws 42 pass through the positioning plate 41 and connect with the fixing hole 12, thereby fixing the position of the rotated positioning plate 41 so that the stacked components 2 can be placed stably on the machine base 1 with excellent positioning effect.

[0021] In this embodiment, multiple through holes 24 are provided, and the multiple through holes 24 are arranged in a rectangular array. Specifically, the multiple through holes 24 are arranged in a rectangular array on the first clamping plate 21. When the dispensing machine 3 injects epoxy resin into the laminated assembly 2, the epoxy resin will flow through the multiple through holes 24 and be injected onto the multiple stacked silicon steel sheets. The injection speed is fast, so that the epoxy resin completely covers and penetrates the multiple stacked silicon steel sheets.
