Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a positioning device for boring holes of special-shaped parts. Background Art

[0002] Boring refers to the further processing of forged, cast or drilled holes. Boring can enlarge the hole diameter, improve accuracy, reduce surface roughness, and better correct the deviation of the original hole axis. When processing special-shaped parts, it is necessary to accurately position the processed parts. However, due to the complex shape of special-shaped parts, the traditional clamping method is slow and positioning is prone to deviation.

[0003] The existing authorized Chinese utility model announcement number is CN217344591U, and the publication date is 2022-09-02. It discloses a boring and positioning device for special-shaped parts, which connects the base plate suitable for the special-shaped parts through the detachable connection between the mounting seat and the base plate, so that only the base plate needs to be replaced for different special-shaped parts, reducing processing costs. At the same time, the two sets of positioning columns on the base plate quickly position the special-shaped parts, and then quickly fix and lock them through the ball head locking pin, which not only makes the workpiece positioning accurate and rapid, the clamping stable and reliable, and ensures the processing quality of the workpiece, but also reduces the clamping time and improves the processing accuracy and efficiency.

[0004] In the above scheme, the mounting seat and the base plate are separately arranged, so that different special-shaped parts can be positioned, but the mounting seat and the base plate are fixed by locking bolts, and the removal and installation of the locking bolts require external tools, which makes it time-consuming to replace the base plate, and easily causes delays in subsequent positioning and boring time, so further improvement and optimization are needed.

[0029] Specifically, the predetermined groove 3 is a transverse groove with a cross-shaped cross-section. One end of the predetermined groove 3 penetrates through the bottom plate 2. The shape of the predetermined plate 9 is adapted to the predetermined groove 3 and is also cross-shaped. The predetermined plate 9 is slidably connected to the predetermined groove 3.
