Description

Technical Field

[0001] This utility model relates to the field of adapter tube tooling technology, specifically a workpiece positioning adapter tube tooling. Background Technology

[0002] The stator is assembled using a press-fit method, but different stator models have different diameters and stack thicknesses. This necessitates changing different positioning fixtures when assembling workpieces for different products to enable automatic stator clamping by the equipment. The stator positioning fixtures are heavy, relatively complex in structure, and result in lengthy changeover times and extended processing cycles. Therefore, finding a solution for quickly and conveniently switching between positioning fixtures for different products has become an urgent problem to solve.

[0003] To address this, a positioning adapter tooling was specially designed between the stator and the positioning fixture. This tooling not only meets the positioning requirements of the stator but also allows for quick switching between different stator models, thus satisfying the production needs of multiple varieties in small batches. Utility Model Content

[0004] The purpose of this utility model is to provide a workpiece positioning adapter tooling, which solves the technical problems of the current stator positioning tooling being heavy, relatively complex in structure, taking a long time to change over, and having a long processing cycle. It achieves the goal of shortening the changeover time and improving production efficiency by reducing the number and complexity of positioning tooling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a workpiece positioning adapter fixture, including a central hole, comprising a positioning fixture limiting groove, a positioning fixture mating surface, a stepped surface one, a stator limiting groove, a stepped surface two, and a stator radial limiting surface. Through the precise cooperation of these components, the workpiece is accurately positioned and stably fixed during the processing, thereby significantly improving the processing efficiency and accuracy of the workpiece and ensuring the stability of the processing quality; the central hole is used to avoid the stator crown.

[0006] The positioning fixture's limiting groove is used for circumferential limiting with the positioning fixture. The positioning fixture also has a limiting groove at the corresponding position. After aligning with the positioning fixture's limiting groove, a cylindrical pin is inserted, thus completing the axial limiting. The diameter of the positioning fixture's mating surface is clearance-fitted with the positioning fixture's hole, with a clearance of 0.08mm, satisfying the radial limiting of this fixture and the positioning fixture.

[0007] The first step surface is used to fit with the step surface corresponding to the positioning fixture to satisfy the axial limiting of the fixture relative to the positioning fixture.

[0008] The stator limiting groove is used to align the stator core outer diameter limiting groove with the stator limiting groove when the stator is installed into this tooling, thereby realizing the circumferential limiting of the stator relative positioning tooling;

[0009] The second step surface is used to support the stator core, thereby achieving axial positioning of the stator relative positioning fixture;

[0010] The stator radial limiting surface is used to achieve a clearance fit between the outer diameter of the stator core and the corresponding diameter of the stator radial limiting surface, with a clearance of 0.08mm, thereby realizing the radial limiting of the stator relative positioning fixture.

[0011] Preferably, the positioning fixture limiting groove is provided on the positioning fixture mating surface, and the stepped surface is formed on the positioning fixture mating surface. The positioning fixture mating surface, through precise mating with the workpiece, ensures the precise positioning and stable fixation of the workpiece during the processing. The mating of the intermediate hole avoids the stator crown, thereby preventing damage to the stator crown during processing, further improving the safety of processing and the yield of the workpiece.

[0012] Preferably, the stator limiting groove is disposed on the stator radial limiting surface, and the second stepped surface is formed on the stator radial limiting surface. Under the combined action of the stator limiting groove and the stator radial limiting surface, the stator core is stably clamped and accurately positioned.

[0013] This utility model provides a workpiece positioning adapter sleeve tooling. It has the following beneficial effects:

[0014] (1) This utility model achieves rapid positioning between the stator and the positioning tooling through a specific design of the workpiece positioning adapter tube tooling, which greatly shortens the changeover time and improves the assembly efficiency. The limiting groove and stepped surface design of the workpiece positioning adapter tube tooling ensures high-precision assembly effect.

[0015] (2) The workpiece positioning adapter tooling of this utility model will not cause any damage to the stator crown during the processing, thus avoiding the risk of processing failure. Furthermore, through precise matching design, it ensures the safety and stability of the processing process and greatly improves the overall quality of the product. Attached Figure Description
