Description

Technical Field

[0001] This utility model relates to the field of positioning ring technology, and in particular to a manual positioning ring. Background Technology

[0002] In the field of metal and non-metal processing, especially in scenarios involving high-precision positioning of CNC pallets and substrates, existing CNC pallet positioners have the following drawbacks when using their positioning rings: Firstly, the fit accuracy between the existing positioning ring and the positioning pins / guiding pins is easily affected by manufacturing tolerances, making it difficult to eliminate dimensional errors in the positioning parts, resulting in low repeatability and failing to meet precision machining requirements. Secondly, during long-term use, wear on the positioning parts accumulates errors, severely affecting equipment stability and processing quality. Furthermore, errors in the mounting hole spacing accuracy and the thermal expansion and contraction effects caused by changes in ambient temperature can both increase the clearance between the positioning ring and the positioning pin, thus increasing the risk of positioning failure. Utility Model Content

[0003] The purpose of this invention is to provide a manual positioning ring to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a manual positioning ring, comprising a positioning sleeve, a conical sleeve, a gasket, a washer, and a retaining ring, wherein the conical sleeve is fitted inside the positioning sleeve, a gasket is provided at the top of the conical sleeve, a washer is provided at the top of the gasket, and a retaining ring is provided at the bottom of the conical sleeve, and the gasket, washer, and retaining ring are all fitted inside the positioning sleeve.

[0005] Preferably, the lower surface of the positioning sleeve has an installation hole, and the tapered sleeve, gasket, washer and retaining ring are all fitted into the installation hole.

[0006] Preferably, a positioning groove is provided in the mounting hole at the position corresponding to the washer, and the washer is disposed in the positioning groove; an annular groove is provided in the mounting hole at the position corresponding to the retaining ring, and the retaining ring is disposed in the annular groove.

[0007] Preferably, the upper surface of the positioning sleeve is provided with a threaded hole, and the threaded hole is connected to the mounting hole.

[0008] Preferably, the outer wall of the positioning sleeve has a frustum surface.

[0009] Preferably, the conical sleeve has a conical hole inside, and a through hole is provided on one side of the outer wall of the conical sleeve, and the through hole is connected to the conical hole.

[0010] Preferably, a stepped groove is provided on the conical sleeve at the position corresponding to the retaining ring, and the retaining ring is disposed in the stepped groove.

[0011] Preferably, the retaining ring has an opening.

[0012] The advantages of this utility model are as follows: A conical sleeve is provided inside the positioning sleeve. The up-and-down movement of the conical sleeve absorbs dimensional errors between the positioning pin or directional pin and the positioning part of the positioning sleeve, wear errors caused by long-term use, accuracy errors in the mounting hole spacing, and hole spacing errors caused by temperature changes. This effectively solves the problem of decreased accuracy due to accumulated errors in existing positioning sleeves, ensuring long-term stable operation of the positioning system, achieving reliable and high-precision repeatable positioning, providing a stable guarantee for precision machining, and significantly improving product processing quality and consistency.
