Description

Technical Field

[0001] The present application relates to the technical field of stator core processing, and in particular to a stator core pressing ring tooling for a CNC lathe. Background Art

[0002] During the stator production process, burrs may appear on the outer edge of the stator core due to the influence of cutting, stamping, stretching and other processing techniques. If these burrs are not handled in time, they will not only affect the appearance of the stator, but may also cause problems in subsequent assembly and use. For example, burrs will increase the friction between the stator and the rotor or other components, resulting in increased wear. Burrs may pierce the insulation layer, causing short circuits or electrical failures.

[0003] In order to eliminate the burrs on the outer edge of the stator, lathe processing is generally used. Lathe processing requires pre-fixing of the stator core pressing ring blank. In the prior art, the stator core pressing ring blank is usually fixed by a pressing ring tool. The general fixing method of the pressing ring tool is to clamp the stator core pressing ring blank on the lathe mounting part, fix it by the mounting part against the inner diameter of the stator core pressing ring blank, and then rotate the core pressing ring blank.

[0004] With regard to the above-mentioned related technologies, the inventors believe that during high-speed rotation, it is difficult to stably fix the stator core pressure ring blank by relying solely on the friction force between the mounting portion and the stator core pressure ring blank on one side. The stator core pressure ring blank may become loose or otherwise not tightened, thus affecting the lathe processing effect. Utility Model Content

[0005] The purpose of the present application is to provide a stator core pressing ring tooling for a CNC lathe, so as to improve the problem that during the high-speed rotation of the chuck, it is difficult to stably fix the stator core pressing ring blank only by relying on the friction force between the chuck and the stator core pressing ring blank, and the stator core pressing ring blank may become loose and not tightened, thereby affecting the processing effect of the lathe.

[0006] The present application provides a stator core pressing ring tooling for a CNC lathe, which adopts the following technical solution:

[0007] A stator core pressing ring tool for a numerically controlled lathe comprises a plurality of chuck blocks, wherein the chuck blocks are in an arc shape and can be spliced ​​together to form a full circle, a placement groove for clamping and placing a stator core pressing ring blank is provided on the arc edge of the chuck block, the placement groove and the chuck block are in a stepped manner, and a pressing plate for cooperating with the placement groove to clamp and fix the stator core pressing ring blank is provided on one side of the chuck block.

[0008] By adopting the above technical scheme, a chuck block is provided to cooperate with and fix the stator core pressure ring blank, and a placement groove is provided to improve the fixing tightness of the stator core pressure ring blank, thereby improving the processing stability; the stator core pressure ring blank is pressed and fixed by providing a pressing disk, so that the stator core pressure ring blank is clamped and fixed, and the fixing tightness is improved, thereby reducing the loosening and looseness of the stator core pressure ring blank during the rotation processing, thereby improving the processing quality.

[0009] Optionally, the pressing plate includes a pressing plate and a fixing plate, the pressing plate is in the shape of an arc concentric with the chuck block, and the fixing plate is fixedly arranged at the center of the arc of the pressing plate and is bolted to the chuck block.

[0010] By adopting the above technical solution, the arc-shaped pressure plate is provided to increase the contact area between the pressure plate and the stator core pressure ring blank, thereby improving the pressing and fixing effect; the pressure plate is fixed by bolts to improve the stability of the pressure plate itself and improve the effect of pressing the stator core pressure ring blank.

[0011] Optionally, the chuck block is provided with a plurality of mounting holes arranged along the center line direction of the circular arc edge of the chuck block corresponding to the fixing plate, and the chuck block is provided with an adjusting waist hole along the direction of the mounting holes corresponding to the fixing plate.

[0012] By adopting the above technical solution, the pressing plate is stably fixed by setting the mounting holes and the matching bolts, and the adjusting waist holes are set to facilitate the fixing of the pressing plate and the adjustment of the fixing position of the pressing plate, that is, to adjust the contact area between the pressing plate and the stator core pressing ring blank, so that the position of the pressing plate can be adjusted according to the width of the stator core pressing ring blank, and the fixing capacity of the pressing plate can be maximized without affecting the processing of the stator core pressing ring blank.

[0013] Optionally, a mounting groove is provided on one side of the pressure plate close to the chuck block, and a rubber pad that can abut against the stator core pressure ring blank is provided in the mounting groove.

[0014] By adopting the above technical solution, the rubber pad is installed by setting the installation groove, and the friction between the pressing plate and the stator core pressing ring blank is increased by setting the rubber pad. By increasing the friction between them, the stator core pressing ring blank is fixed more stably.

[0015] Optionally, a cushion block is provided on a side of the chuck block away from the pressing plate, and the chuck block is fixed to the lathe mounting part by bolts penetrating the cushion block.

[0016] By adopting the above technical solution, the pad is used to increase the distance between the chuck block and the lathe mounting part. If the distance between the chuck block and the lathe mounting part is too small, the strip-shaped and spiral chips cut out during the processing will be drawn into the gap between the tooling body and the lathe chuck, which is not conducive to cleaning. By setting the pad to increase the distance between the chuck block and the lathe mounting part, it is convenient to clean the chips in the gap.

[0017] Optionally, the chuck block is provided with a through groove for hollowing out.

[0018] By adopting the above technical solution, the raw materials of the chuck block are reduced by setting the through groove, thereby reducing the production cost of the chuck block and reducing the weight of the chuck block, which is beneficial to processing and improves processing efficiency.

[0019] Optionally, the placement slot width is smaller than the width of the stator core pressing ring blank.

[0020] By adopting the above technical solution, the width of the placement slot is smaller than the width of the stator core pressing ring blank, so that during the process of turning the outer side of the stator core pressing ring blank on the lathe, the turning tool is prevented from contacting the chuck block, damaging the turning tool and the chuck block, and causing unnecessary economic losses.

[0021] Optionally, an arc-shaped opening groove concentric with the placement groove is provided in the placement groove.

[0022] By adopting the above technical solution, the open groove reduces the contact area between the placement groove and the stator core pressing ring blank, avoiding the metal surface being too smooth. After the processing is completed, the stator core pressing ring blank and the placement groove are too tightly fitted and difficult to separate. The placement groove is provided to facilitate the disassembly of the stator core pressing ring blank.

[0023] In summary, the present application includes at least one of the following beneficial technical effects of a stator core pressing ring tooling for a CNC lathe:

[0024] 1. The stator core pressing ring blank is fixed by setting a chuck block, and the fixing tightness of the stator core pressing ring blank is improved by setting a placement groove, thereby improving the processing stability; the stator core pressing ring blank is clamped and fixed by setting a pressing plate, thereby clamping and fixing the stator core pressing ring blank, improving the fixing tightness, reducing the loosening and loosening of the stator core pressing ring blank during the rotation processing, and improving the processing quality;

[0025] 2. The pressing plate is stably fixed by setting mounting holes and bolts, and the adjusting waist holes are set to facilitate fixing the pressing plate and adjusting the fixing position of the pressing plate, that is, adjusting the contact area between the pressing plate and the stator core pressing ring blank, so as to adjust the position of the pressing plate according to the width of the stator core pressing ring blank, maximizing the fixing capacity of the pressing plate without affecting the processing of the stator core pressing ring blank;

[0026] 3. The rubber pad is installed by setting the installation groove, and the friction between the pressing plate and the stator core pressing ring blank is increased by setting the rubber pad. By increasing the friction between them, the stator core pressing ring blank is fixed more stably. BRIEF DESCRIPTION OF THE DRAWINGS
