Description

Technical Field

[0001] The utility model relates to the field of positioning of thin-walled annular parts, in particular to a positioning device applied to thin-walled annular parts. Background Art

[0002] Large-diameter, thin-walled annular parts are relatively large, typically measuring φ1484±5 or larger, and typically have thin walls less than 32.5mm. These parts require a fixed position when sawing. Existing sawing machines, however, struggle with this because the blanks are typically elliptical rather than circular. This results in a smaller contact area between the clamping block and the fixture, resulting in weak clamping force and a tendency for the part to shift or slide during sawing. Furthermore, this shifting and sliding of the blank during sawing can lead to uneven force on the saw blade, which can easily break if the force exceeds a certain limit. Utility Model Content

[0028] In this embodiment, by providing the first protrusion 422 and the second protrusion 425, the thin-walled ring part positioning device can increase the contact area between the locking module 42 and the large-diameter thin-walled ring part 50 when positioning the large-diameter thin-walled ring part 50, thereby increasing the friction force and making the positioning more secure, thereby solving the problem of loose fixation of the large-diameter thin-walled ring part 50 during sawing in the prior art.

[0029] In some embodiments, as Figure 1 As shown, the sliding assembly 30 is detachably connected to the base 10 in a circumferential array.

[0030] In this embodiment, by detachably connecting the sliding components 30 to the base 10 in a circumferential array, the large-diameter thin-walled annular component 50 can be subjected to more uniform force when positioning the large-diameter thin-walled annular component 50 .

[0045] In this embodiment, by setting the included angles between the first support module 21, the second support module 22, and the third support module 23 to be equal, the force applied to the large-diameter thin-walled annular component 50 during support can be more uniform, resulting in a better support effect.

[0046] The working principle of this utility model is:

[0047] Place the large-diameter thin-walled ring part 50 on the base 10, and make each locking module 42 located in the annular cavity of the large-diameter thin-walled ring part 50, control the sliding assembly 30 to drive each locking module 42 to move toward the inner wall of the large-diameter thin-walled ring part 50, so that the first protrusion 422 and the second protrusion 425 lock the position of the large-diameter thin-walled ring part 50.

[0048] In the above, the sliding assembly 30 can be an electric cylinder, the first positioning module 31 can be the fixed end of the electric cylinder, and the sliding module 32 can be the sliding end of the electric cylinder.
