Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for machining, and in particular to a reversible double-center alignment device. Background Technology

[0002] In machining processes, some parts require multiple machining steps or have multiple machined surfaces. To ensure the uniformity of angles and machining accuracy of various parts, a aligning device is needed to determine a unified positive datum auxiliary line for each machining step or machined surface. In practical applications, the aligning device has only one center head, requiring repeated alignment of two points to ensure the datum auxiliary line is vertical or horizontal. Furthermore, existing aligning devices have poor versatility. On vertical machine tools, the tool holder clamping center head points downwards, making it difficult to align the part vertically; on horizontal machine tools, the tool holder clamping center head points are horizontal, making it difficult to align the part horizontally.

[0036] like Figure 4 As shown, the second center base I consists of an integrally connected center seat I1 and a limiting shaft I2.

Figure 5 and Figure 4As shown, the limiting shaft I2 of the second center base I can extend and retract along the axial direction of the horizontal rotating rod D according to the size of the part, and the first center base B can rotate freely from 0 to 90° along the first shaft hole A3 of the reference handle A, thereby realizing the alignment of the tapered surface and the irregular plane.

[0041] like Figure 1 , Figure 2 and Figure 5 As shown, a first limiting bolt B8 can be installed in the first limiting threaded hole B6 and / or a second limiting bolt B9 can be installed in the second limiting threaded hole B7, depending on the processing requirements. The limiting principle of the first limiting bolt B8 and the second limiting bolt B9 is that when the horizontal rotating rod limiting surfaces D5 on both sides of the rotating bushing D1 of the horizontal rotating rod D move to the corresponding limiting bolt positions, the horizontal rotating rod limiting surfaces D5 are blocked by the first limiting bolt B8 and / or the second limiting bolt B9, thereby achieving the limiting.

[0042] The reversible double-center alignment device of this embodiment employs a combination structure of two centers, enabling rapid and accurate alignment of multiple planes, significantly saving alignment auxiliary time. It is convenient and quick to operate, suitable for alignment of multiple planes, and avoids the waste of auxiliary time when using auxiliary tools with a single center to align drawing references. The device of this embodiment is applicable to both horizontal and vertical machine tools, allowing for simultaneous horizontal and vertical line drawing and alignment on different machines.

[0043] In this embodiment of the reversible dual-center alignment device, the first center F and the second center J can be used in combination or individually. When only the first center F needs to be used, the horizontal rotating rod D and related components of the second center J can be disassembled.

[0044] like Figure 6 As shown, in practical applications, an angle reference line B10 is set on the first top base B, and an angle scale line D6 is set on the rotating bushing D1 of the horizontal rotating rod D. The angle reference line B10 and the angle scale line D6 are used together to achieve precise control and positioning of the rotation angle of the horizontal rotating rod D.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
