Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of punching sheet positioning and separation, in particular to a stator punching sheet inner hole positioning and separation core shaft. Background Art
[0002] The blanks of the punching robot need to be stored in advance and stacked to a certain height before loading. Because the surface of the punch is smooth, the weight of the stacked blanks causes a large adsorption force between the two adjacent blanks. When the robot takes the blanks, adhesion often occurs. To solve this problem, four positioning mandrels are generally used to position the blanks in the early days. A long groove is milled on the head of the mandrel 5, and a magnetic steel 8 is installed to separate the two blanks by magnetic force. Figure 1 As shown, at the tangent point between the outer circle of the core shaft 5 and the inner hole of the punching sheet 6, there are two corners of the magnet that hinder the positioning of the punching sheet, so the two corners will be polished after the installation of the magnet. After polishing, the magnetism of the magnet will be weakened. The effect is acceptable for separating small-sized stator sheets, but the effect will disappear when the size of the punching sheet becomes larger, which is not conducive to the positioning and separation of the punching sheet. Summary of the invention
[0003] The utility model aims to solve the above technical problems and provide a stator punching inner hole positioning and spreading core shaft, which can adapt to the spreading of stator punchings of various sizes and has a significant spreading effect.
[0004] In order to achieve the above-mentioned technical purpose and meet the above-mentioned technical requirements, the technical solution adopted by the utility model is: a stator punching inner hole positioning and spreading core shaft, including a positioning shaft body, characterized in that: a magnetic ring sleeve is arranged on the positioning shaft body, a magnetic ring assembly is arranged in the magnetic ring sleeve, an aluminum pressure plate is arranged on the magnetic ring assembly, and screws pass through the aluminum pressure plate, the magnetic ring assembly, the magnetic ring sleeve and are connected to the positioning shaft body.
[0005] Preferably, the magnetic ring assembly comprises a plurality of magnetic rings, and a plastic spacer is provided between two adjacent magnetic rings.
[0006] Preferably, a positioning hole is provided at the top end of the positioning shaft body, and a positioning boss is provided at the bottom end of the magnetic ring sleeve, and the positioning boss cooperates with the positioning hole for positioning.
[0007] Preferably, the outer circle of the magnetic ring sleeve is in the same position as the outer circle of the positioning shaft body.
[0008] Compared with the traditional structure, the utility model has the following beneficial effects: simple structure, good sheet separation effect, using the magnetic force of the magnetic ring to separate two adjacent punching sheets, ensuring that the robot only takes one punching sheet when taking the material, and is no longer limited by the size of the punching sheet.

[0013] The utility model is further described below.
[0014] Refer to the attached Figure 2-3 A stator punching inner hole positioning and spreading core shaft comprises a positioning shaft body 4, a stainless steel magnetic ring sleeve 1 is arranged on the positioning shaft body 4, a magnetic ring assembly 3 is arranged in the stainless steel magnetic ring sleeve 1, an aluminum pressing plate 2 is arranged on the magnetic ring assembly 3, and screws pass through the aluminum pressing plate 2, the magnetic ring assembly 3, the stainless steel magnetic ring sleeve 1 and are connected with the positioning shaft body 4.
[0015] In this preferred embodiment, the magnetic ring assembly 3 includes a plurality of magnetic rings 31 , and a plastic spacer 32 is provided between two adjacent magnetic rings 31 .
[0016] In this preferred embodiment, a positioning hole is provided at the top end of the positioning shaft body 4 , and a positioning boss 11 is provided at the bottom end of the stainless steel magnetic ring sleeve 1 , and the positioning boss 11 cooperates with the positioning hole for positioning.
[0017] In this preferred embodiment, the outer circle of the stainless steel magnetic ring sleeve 1 is in the same position as the outer circle of the positioning shaft body 1 .
[0018] In specific implementation, the positioning shaft body 4 is the installation base of the entire split part. A positioning hole is processed at the top, which cooperates with the positioning boss 11 below the stainless steel magnetic ring sleeve 1 to ensure that the outer circle positions of the stainless steel magnetic ring sleeve 1 and the positioning shaft body 4 are consistent. The magnetic ring 31 is placed in the inner hole of the magnetic ring sleeve 1, and the magnetic rings 31 are separated by plastic spacers 32. To ensure that the magnetic force is not affected, the wall thickness of the magnetic ring sleeve 1 is only 0.5mm. After the magnetic ring 31 is installed in the magnetic ring sleeve 1, it is tightened with an aluminum pressure plate 2 and stainless steel screws.
[0019] The punching sheets are fixed in position at the circumscribed circles of the four positioning and separating mandrels. When the top punching sheet reaches the stainless steel magnetic ring sleeve 1, the magnetic force of the magnetic ring 31 will separate the two adjacent punching sheets, and the topmost punching sheet will be suspended to ensure that only one punching sheet is taken when taking the material.
[0020] After verification and long-term actual use, the above processing dimensions, material usage and assembly methods have achieved significant sheet separation effects and are no longer limited by the size of the punched sheets.
